Abstract
The invention discloses a lever block, and belongs to the technical field of design of hoisting devices. The lever block comprises an upper hoisting hook, a lever fixing end, a chain, a lower hoisting hook, a fixing cover, a locking buckle, a lever, a spring buckle and a sprocket box, wherein the upper hoisting hook is fixed to the top of the sprocket box; the whole device can be hung on a workshop truss through the upper hoisting hook; a sprocket is fixed inside the sprocket box, and a sprocket shaft extends out of the sprocket box; the lever is arranged on the sprocket shaft in a sleeving mode through the lever fixing end and fixed to the sprocket shaft through the fixing cover; and the chain winds around the sprocket in an inner cavity of the sprocket box, the lower hoisting hook is fixed to the bottom of the chain and used for hooking a weight when the weight is hoisted, and then the weight is conveyed to the needed position by rotating the lever. The lever block disclosed by the invention is simple in structure, convenient to operate, low in cost, good in safety and good in hoisting reliability. The lever fixing end is high in bearing capacity, is convenient to hold by hand and saves efforts during operation.
Description
Technical field
The present invention relates to chain sling design field, particularly relate to a kind of Lever Blocks.
Background technology
In the middle of mechanical industry and daily life, we it is frequently necessary to carry out at certain interval range
The carrying work of weight, too big due to the weight of weight in some cases, use traditional artificial
Mode can cause the labor intensity of workman greatly, and handling efficiency is low, and the weight used in the past played lifting
Put due to the existing defects when structure designs, cause weight that operation fiber crops can occur during transporting
Tired, efficiency is low, weight the most even can be occurred to drop suddenly during transporting, cause great
Safety problem, therefore a kind of simple in construction of design, easy to operate, low cost, and safety is good,
Lifting good reliability, the bearing capacity that end fixed by spanner is strong, and the Lever Blocks of rapid operation seems
The most necessary.
Summary of the invention
The purpose of the present invention is contemplated to overcome former weight boom hoisting troublesome poeration, efficiency
Low, the defect of poor stability, devises a kind of Lever Blocks, and simple in construction is easy to operate,
Low cost, safety is good, lifts by crane good reliability, and the bearing capacity that end fixed by spanner is strong, operation
Laborsaving.
Solve the technical problem that required by the present invention and can be achieved through the following technical solutions:
A kind of Lever Blocks, including hook, chain-wheel box, described hook is fixed on described chain
The top of roller box, whole device can be suspended on the truss of workshop by described hook, also include
Spanner fixes end, chain, lower suspension hook, fixing lid, tight locking button, spanner, snak link, sprocket wheel
Being fixed on the inside of described chain-wheel box, sprocket shaft stretches out from described chain-wheel box, and described spanner is by institute
State spanner fixed end cap on sprocket shaft, fixed with sprocket shaft by described fixing lid, described chain
Bar walks around sprocket wheel at the inner chamber of described chain-wheel box, the bottom of described chain be fixed with described under hang
Hook.
It is provided with described snak link on described lower suspension hook.
Described tight locking button it is provided with on described spanner.
The described spanner of described spanner fixing end width dimensions is big.
The operating side of described spanner is circular configuration, and size end more fixing than described spanner is little.
Owing to have employed above technical scheme, present invention have the advantage that
Use hook, chain-wheel box, chain, lower suspension hook, fixing lid, tight locking button, spanner,
Snak link combines designed Lever Blocks, and lower suspension hook is provided with snak link, and weight is in fortune
Being difficult to during sending drop, safety is good, and spanner is provided with tight locking button, can be by locking
Spanner is fixed by button, prevents during hoisting heavy the own wt due to weight to fall, lifting
Good reliability, safety is good, and the spanner of spanner fixing end width dimensions is big, beneficially spanner with
Fixing of sprocket shaft, during rotation, the bearing capacity that end fixed by spanner is strong, and the operating side of spanner is
Circular configuration, size end more fixing than spanner is little, and during work, hands grips convenient, rapid operation.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be prone to effect
Understand and understand, below in conjunction with being specifically illustrating, the present invention is expanded on further.
A kind of Lever Blocks, including hook 1, spanner fix end 2, chain 3, lower suspension hook 4,
Fixing lid 5, tight locking button 6, spanner 7, snak link 8, chain-wheel box 9, hook 1 is fixed on
The top of chain-wheel box 9, whole device can be suspended on the truss of workshop by hook 1, sprocket wheel
(being not drawn in figure) is fixed on the inside of chain-wheel box 9, and sprocket shaft stretches out from chain-wheel box 9, pulls
Hands 7 is enclosed within sprocket shaft by the fixing end 2 of spanner, is fixed with sprocket shaft by fixing lid 5, chain
Bar 3 walks around sprocket wheel at the inner chamber of chain-wheel box 9, and the bottom of chain 3 is fixed with lower suspension hook 4, rises
Being hooked by weight by lower suspension hook 4 during lift heavy thing, rotating spanner 7 can transport weight to required
Position, simple in construction, easy to operate, low cost.
It is provided with snak link 8 on lower suspension hook 4, when weight is hung to lower suspension hook 4, snak link
8 open conveniently, and after weight hangs up properly, the elastic force of snak link 8 can make snak link 8 rebound, will
Lower suspension hook 4 seals, and weight is difficult to drop during transporting, and safety is good.
Tight locking button 6 it is provided with on spanner 7, during rotating spanner 7 lifting heavy, as
