Abstract
The utility model relates to an electric hoist with double hooks and chains, comprising a motor, chain wheels, a shaft, the chains, lift hooks. The utility model is provided with the left chain wheel and the right chain wheel which are connected with each other through the shaft or a shaft coupling, and the left chain wheel and the right chain wheel drive respective lift hooks to simultaneously move through the chains. For speed change and safety, a speed change device for a gear set and a safety protecting device for the gear set are arranged between the motor and the chain wheels, a locking device is arranged on the head of each lift hook, and limiting devices are arranged among the chains and the chain wheels. The utility model has the advantages of small size, steady lift, accurate position, good maneuverability, etc. is applied to an automation line for producing motor cars or other automated production lines.
Description
The utility model relates to the loop chain hoisting crane, relates in particular to the double hook Electric Chain Blocks.
Electric block in the hoisting crane generally can be divided into steel-wire rope type electric block and Electric Chain Blocks.The steel-wire rope type electric block volume is big, complex structure, and the suspension hook location is inaccurate; The Electric Chain Blocks volume is little, and is simple in structure, and accurate positioning is now just being used more and more widely.But the electric block that uses all is single hook structure now, hangs the development need that thing stability and accurate positioning can not be satisfied some industry.Along with the raising that lifting object stability is required, some enterprise has developed the double hook steel-wire rope type electric block.Yet because the defective that steel-wire rope type electric block itself exists makes that double hook steel-wire rope type electric block volume is big, easily move the location, can not satisfy the needs of market development.
The purpose of this utility model is to provide a kind of volume little, accurate positioning, synchronization-moving double hook Electric Chain Blocks.
The utility model double hook Electric Chain Blocks is made up of electrical motor, sprocket wheel, axle, chain and suspension hook, and sprocket wheel is a left and right sides sprocket wheel, connects by axle or coupler, and the chain that sprocket wheel drives separately makes two same moved further of suspension hook.This double hook Electric Chain Blocks manoevreability is good, applied widely, can be applicable on car production automation line or other automatic assembly line.
Fig. 1 always schemes for the utility model double hook Electric Chain Blocks.1 electrical motor among the figure, 2 right sprocket wheels, 3,4 coupler, 5 chains, 6 suspension hooks, 7 left sprocket wheels, 8 gear clusters slow down, 9 safety guards.
Below in conjunction with drawings and Examples the utility model is further described.
The double hook Electric Chain Blocks is made up of electrical motor, sprocket wheel, axle, chain and suspension hook.Electrical motor 1 drive sprocket, sprocket wheel are left sprocket wheel 7 and right sprocket wheel 2, about two sprocket wheels link up by axle 3, the length of axle is as inadequately, can pass through coupler 4 connections such as grade, left and right sides sprocket wheel is rotated synchronously, left and right sides sprocket wheel moves by chain 5 drives suspension hook 6 separately separately.Because left and right sides sprocket wheel is to rotate synchronously, the then mobile also synchronized operation of suspension hook separately.Left and right sides sprocket wheel also can by chain drive separately driven suspension hook synchronized operation again by movable sprocket.For the purpose of speed change and safety guard-safeguard, gear cluster deceleration 8 and safety guard 9 are arranged between electrical motor and sprocket wheel, on the suspension hook head, blocking device is arranged, on the chain or under the sprocket wheel inhibiting device is being arranged.Use the advantage of loop chain to be that the volume of whole double hook Electric Chain Blocks is compared greatly with double hook steel-wire rope type electric block of the same type and dwindle, and two suspension hook fixed distance of double hook loop chain.And the double hook steel rope is in operation two suspension hooks distance in constantly changing, this has brought influence to the stability of lifting object and the accuracy of location, and along with the increase of sling height, the also corresponding increase of the volume of steel-wire rope type electric block, this has also limited its field of application.
Embodiment: double hook Electric Chain Blocks; hoisting capacity is 1000 kilograms; hook is apart from 500 millimeters; double hook duplicate rows chain, left and right sides sprocket wheel is connected with coupler by axle, has gear cluster to slow down and safety guard between electrical motor and sprocket wheel; left and right sides sprocket wheel is driven separately suspension hook by chain drive by movable sprocket; make the same moved further of suspension hook, between chain and sprocket wheel inhibiting device is arranged, the suspension hook head has blocking device.
The utility model double hook Electric Chain Blocks has that volume is little, and it is steady to hang thing, accurate positioning, and characteristics such as manoevreability is good, applied widely, can be applicable on car production automation line or other automatic assembly line.
