Mumotokari ine mabhureki emhepo, nzvimbo yekupaka uye yakasarudzika (kana yekubatsira) brake control kifaa inopihwa - bhuku repneumatic crane.Verenga zvese nezve kupaka mabhureki mavharuvhu, mhando dzawo, dhizaini uye misimboti yekushanda, pamwe nekusarudzwa kwakaringana nekutsiviwa kwemidziyo iyi muchinyorwa.
Chii chinonzi parking brake valve?
Parking brake valve (hand brake valve) - iyo inodzora chinhu cheiyo brake system ine pneumatic drive;crane yeruoko yakagadzirirwa kudzora midziyo yekuburitsa mota (spring energy accumulators) iri chikamu chekupaka uye spare kana yekubatsira braking masisitimu.
Iyo yekupaka uye yakasarudzika (uye mune dzimwe nguva anobatsira) mabhureki emotokari ane pneumatic braking masisitimu anovakwa pahwaro hwechirimo simba accumulators (EA).MaEA anogadzira simba rinodiwa kudzvanya mabhureki padhi padhiramu nekuda kwechirimo, uye disinhibition inoitwa nekupa mweya wakamanikidzwa kuEA.Iyi mhinduro inopa mukana wekubhureki kunyangwe pasina mweya wakamanikidzwa muhurongwa uye inogadzira mamiriro ekushanda kwakachengeteka kwemotokari.Mhepo inopihwa kuEA inodzorwa nemaoko nemutyairi achishandisa yakakosha yekupaka mabhureki valve (kana kungoti bhuku remhepo crane).
Iyo yekumisa brake valve ine akati wandei mabasa:
● Kupiwa kwemhepo yakamanikidzwa kune EA kuti isunungure motokari;
● Kusunungurwa kwemhepo yakamanikidzwa kubva kuEA panguva yekuputika.Zvakare, zvese zviri zviviri kubuda ropa kwemweya paunenge uchigadzika pabhureki rekupaka, uye chidimbu kana spare / yekubatsira brake iri kushanda;
● Kutarisa kushanda kwemabhureki ekupaka ezvitima zvomumugwagwa (matirakita ane turera).
Iyo parking brake crane ndeimwe yekutonga kukuru kwemarori, mabhazi nemimwe michina ine mabhureki emhepo.Kusashanda zvakanaka kwechishandiso ichi kana kuputsika kwayo kunogona kuve nemhedzisiro inosiririsa, saka crane ine mhosva inofanirwa kugadziriswa kana kutsiviwa.Kuti usarudze crane yakakodzera, unofanirwa kunzwisisa marudzi aripo emidziyo iyi, magadzirirwo avo uye musimboti wekushanda.
Mhando, dhizaini uye musimboti wekushanda kweiyo parking brake crane
Mavharuvhu ekumisa mabhureki anosiyana mukugadzira uye kushanda (nhamba yemapini).Nekugadzirwa, cranes ndeiyi:
● With swivel control knob;
● Nekudzora lever.
Parking brake valve ine swivel handle
Kupaka brake valve ine mubato wakatsauka
Kushanda kwemhando mbiri dze cranes kunoenderana nemisimboti yakafanana, uye misiyano iri mudhizaini yedhiraivha uye zvimwe zvekutonga - izvi zvinokurukurwa pazasi.
Panyaya yekushanda, cranes ndeiyi:
● Kudzora mabhureki emotokari imwe chete kana bhazi;
● Kudzora mabhureki echitima chemumugwagwa (tirakita ine turera).
Mune crane yerudzi rwekutanga, zvinobuda zvitatu chete zvinopihwa, mumudziyo wemhando yechipiri - ina.Zvakare mumacranes ezvitima zvemumugwagwa, zvinokwanisika kudzima kwenguva pfupi trailer brake system kuti utarise mashandiro eiyo parking brake yetirakita.
Ese mavharuvhu ekupaka mabhureki ane-chikamu, reverse chiito (sezvo achipa nzira yemhepo munzira imwe chete - kubva kune vanogamuchira kuenda kuEA, uye kubva kuEA kuenda kumhepo).Chigadzirwa chacho chinosanganisira vharuvhu yekudzora, piston-mhando yekutevera mudziyo, valve actuator uye huwandu hwezvinhu zvinobatsira.Zvikamu zvese zvinoiswa mukesi yesimbi ine matatu kana mana anotungamira:
● Kutengeswa kubva kune vanogamuchira (kupindwa kwemhepo yakamanikidzwa);
● Kubvisa kuEA;
● Sunungura mudenga;
Muma cranes ezvitima zvemumugwagwa, zvinobuda kune brake control valve yetirailer / semi-trailer.
Iyo crane drive, sezvataurwa pamusoro, inogona kuvakwa pahwaro hwechibatiso chinotenderera kana chibatiso chakatsauka.Muchiitiko chekutanga, chivharo chevhavha chinotungamirirwa ne screw groove yakagadzirwa mukati mevhavha yemuviri, iyo iyo inotungamira cap inofamba kana mubato watendeuka.Kana mubato wacho wakashandurwa newachi, chivharo pamwe chete netsinde chinodzikiswa, kana chichishandurwa neclockwise, inosimuka, iyo inopa kutonga kwevhavha.Panewo chivharo pachivharo chinotenderera, icho, kana mubato watenderedzwa, chinodzvanya chivharo chekuwedzera chebhureki.
Muchiitiko chechipiri, vharuvhu inodzorwa nekamera yeimwe chimiro chakabatana nemubato.Kana mubato watsauka munzira imwe kana imwe, kamera inodzvanya pahunde yevharuvhu kana kuiburitsa, ichidzora kuyerera kwemhepo.Muzviitiko zvose izvi, zvibato zvine nzira yekuvhara munzvimbo dzakanyanyisa, kubvisa kubva panzvimbo idzi kunoitwa nekukwevera mubato pamwe chete neaxis yayo.Uye mumacranes ane mubato wakatsauka, kutarisa kushanda kweiyo parking brake kunoitwa, pane zvinopesana, nekudzvanya mubato pamwe neaxis yayo.
Nheyo yekushanda kwevhavha yekupaka bhureki mune yakajairika kesi inotevera.Munzvimbo yakanyanyisa yakagadziriswa yekubata, inoenderana neyakavharwa kupaka bhureki, iyo valve inomisikidzwa nenzira yekuti mhepo kubva kune vanogamuchira inopinda zvakasununguka muEA, ichisunungura mota.Kana mabhureki ekupaka abatwa, mubato unoendeswa kunzvimbo yechipiri yakagadziriswa, vharuvhu inogoverazve kuyerera kwemhepo nenzira yekuti mhepo kubva kune vanogamuchira inovharwa, uye maEA anotaurirana nemhepo - kudzvanywa mavari kudonha, zvitubu zvinodzima uye zvinopa mabhureki emotokari.
Munzvimbo dzepakati pemubato, mudziyo wekutevera unouya mukushanda - izvi zvinogonesa kushanda kweiyo spare kana yekubatsira brake system.Nekutsauka kwechikamu chemubato kubva kuEA, imwe huwandu hwemhepo inoburitswa uye mapadhi anoswedera kune dhiramu rebhureki - iyo inodiwa braking inoitika.Kana mubato unomira panzvimbo iyi (inobatwa nemaoko), chigadziro chekutsvaga chinotanga, chinovhara mutsara wemhepo kubva kuEA - mhepo inorega kubuda uye kudzvinyirira muEE kunoramba kuripo.Nekumwe kufamba kwechibato munzira imwechete, mhepo kubva kuEA inobuda ropa zvakare uye kwakawedzera mabhureki.Kana mubato unofamba uchienda kune rumwe rutivi, mweya unopihwa kubva kune vanogamuchira kuenda kuEA, izvo zvinotungamira mukudzivirirwa kwemotokari.Saka, kusimba kwebhureki kwakaenzana nekona yekutsauka kwemubato, iyo inovimbisa kugadzikana kutonga kwemotokari kana paine yakashata service brake system kana mune mamwe mamiriro.
Mune cranes yezvitima zvemumugwagwa, zvinokwanisika kutarisa kupaka brake ye lever.Cheki yakadaro inoitwa nekufambisa mubato kunzvimbo yakakodzera ichitevera chinzvimbo chebhureki rakazara (kushandisa bhureki rekupaka), kana nekuitsikirira.Muchiitiko ichi, vheji yakakosha inopa kudzoreredzwa kwekumanikidza kubva kumutsara wekutonga weiyo brake system yetrailer / semi-trailer, inotungamira mukuburitswa kwayo.Nekuda kweizvozvo, tirakita inoramba yakabhurekidzwa chete neE zvitubu, uye semi-tirailer inovharirwa zvachose.Cheki yakadaro inokutendera kuti uongorore kushanda kweiyo parking brake yetirakita yechitima chemugwagwa paunenge uchipaka pamateru kana mune mamwe mamiriro.
Ivhavhavha yekupaka yakasungirirwa pa dashboard yemotokari kana pasi pekabhu padivi pechigaro chemutyairi (kurudyi), yakabatanidzwa kune pneumatic system nemapaipi matatu kana mana.Zvinyorwa zvinoshandiswa pasi pecrane kana pamuviri wayo kudzivirira kukanganisa mukutonga kweiyo brake system.
Nyaya dzekusarudza, kutsiva uye kugadzirisa kweiyo parking brake crane
Ivhavha yekupaka motokari panguva yekushanda kwemotokari inogara iri pasi pekumanikidzwa kwakanyanya uye inoratidzwa kune zvakasiyana-siyana zvakashata, saka kune mukana mukuru wekushaya simba.Kazhinji kazhinji, mavharuvhu, zvitubu uye zvikamu zvakasiyana-siyana zvekuisa chisimbiso zvinokundikana.Kusashanda kwecrane kunoonekwa nekusashanda kweiyo yese yekupaka system yemotokari.Kazhinji, kana kukanganisa kwechikwata ichi, hazvibviri kunonoka kana, zvakasiyana, kusunungura motokari.Mhepo inodonha kubva papombi inogoneka zvakare nekuda kwekuvharwa kwakashata kwekusangana kwematerminals nemapaipi, pamwe nekuumbwa kwekutsemuka uye kuputsika mudzimba.
Crane yakashata inobviswa kubva mumotokari, inoparadzaniswa uye inoiswa pasi pekuonekwa mhosva.Kana dambudziko riri muzvisimbiso kana muvharo, ipapo zvikamu zvinogona kuchinjwa - zvinowanzopiwa mumakiti ekugadzirisa.Kana pakaputsika zvakanyanya, crane inochinja pakuungana.Chishandiso chemhando imwechete uye modhi iyo yakaiswa pamotokari kare inofanira kutorwa kuti inotsiviwa.Hazvibvumirwi kuisa 3-lead cranes pamatirakita anoshandiswa nematirakita / semi-trailer, nekuti hazvigoneke kuronga kutonga kwetrailer brake system nerubatsiro rwavo.Zvakare, iyo crane inofanirwa kuenderana neyekare maererano nekumanikidza kwekushanda uye zviyero zvekuisa.
Kutsiviwa kwecrane kunoitwa zvinoenderana nemirairo yekugadziriswa kwemotokari.Munguva yekushanda kunotevera, chigadzirwa ichi chinogara chichiongororwa, kana zvichidiwa, zvisimbiso zvinotsiviwa mairi.Kushanda kwecrane kunofanirwa kuenderana nemaitiro akagadzwa nemugadziri wemotokari - chete munyaya iyi iyo yose braking system ichashanda nemazvo uye yakavimbika mumamiriro ese.
