Description
Technical field
The utility model is related to a kind of chain block, belongs to crane gear.
Background technology
The chain block critical part of current market is all manufactured from steel material, has many between weight weight and two wallboards
Institutional part and functional features, pull chain and hoisting-chain and an open space are almost in body.And chain block
Substantially open field operation, use environment is more severe, and the body into after dust of intaking card chain easily occurs, jumps chain, climb chain, rub
Situations such as pad is skidded, easily causes any property loss and personal injury.And because the precision of plate stamping is not high, cause after assembling
Precision it is not high, finally show that the overall efficacy of cucurbit is relatively low.
Specific manifestation is as follows：
1. cucurbit vertical lifting.When quick pulling pulls chain, easily generation chain non-stress end, which is takeoff, is caught in bangle wheel
Between bangle wheel case.The lighter can then be adjusted to good working order by falling handle zip strip, severe one must be by special
Industry personnel can normally use after fixing a breakdown.
2. cucurbit is in horizontal plane（Certain angle）During traction, pull chain and easily form stuck with bangle wheel case
Point, it is not smooth to cause to pull chain operation, or even cisco unity malfunction.
Above-mentioned situation, if dealing with improperly, easily leads to a disaster once occurring under the situation of load.
Utility model content
The utility model is according to the above deficiency, there is provided a kind of chain block of integral housing, main housing is integrally pressed
Type casting moulding.
The technical solution of the utility model is：
A kind of chain block of integral housing, including：
Left outside wallboard；
Right outer wall plate；
Bangle wheel case；
Left outside wallboard and right outer wall plate is connected as a single entity through dowel, bangle wheel case and the left outside wallboard being connected as a single entity and the right side
Side fascia fixes the housing to form chain block by multiple bolts.
Further, the first upper protruding block, bottom are provided with the top of the left outside wallboard and are provided with the first lower protruding block, accordingly
The second upper protruding block, bottom are provided with the top of ground, the bangle wheel case and is provided with the second lower protruding block, and during installation, first is convex
Block is close to the second upper protruding block, the first lower protruding block and is close to the second lower protruding block, and the multiple bolt is each passed through the first upper protruding block and
The through hole of the through hole of two upper protruding blocks, the first lower protruding block and the second lower protruding block is fixed through nut.
The first guide chain groove is provided with described left outside wallboard, the bangle wheel case is provided with the second guide chain groove, first
Guide chain groove and the second guide chain groove are in arc-shaped, in addition to guide chain block, and the guide chain block is provided with two guide chain sliding blocks and guide chain hole, two
Guide chain sliding block is respectively embedded into the first guide chain groove and the second guide chain groove and can be along the first guide chain groove and the second guide chain groove circumferentially
Track is slided, and guide chain hole, which is penetrated, pulls chain.
Preferably, the excircle of the guide chain block is provided with guide chain projection, the guide chain hole passes through the guide chain projection.
Preferably, the guide chain hole is in cross, the shape adaptation with pulling chain.
The beneficial effects of the utility model are：Body is molded using integral die-cast, and the entirety for devising hoisting-chain chain is led
To mechanism, it is ensured that do not occur card chain phenomenon under any state；Enclosed construction is avoided because foreign object falls into sprocket wheel and chain simultaneously
Card chain phenomenon is caused between bar；This structure not only reduces assembly process, simplifies mounting process, and improves the steady of housing construction
The precision of qualitative and each gyroaxis.
