Abstract
The utility model relates to a double-hook upside down type electric chain hoist, and solves problems that energy is wasted and the hoisting is instable due to the fact that a conventional hoist is required to be manually carried and fixed with a main hook and a chain is required to be inversed when secondary hoisting is performed. The double-hook upside down type electric chain hoist comprises a motor, a transmission mechanism, a reel and an iron chain, wherein the reel is mounted on a wall through a wall attaching support, and an upper fixing shaft and a lower fixing shaft are arranged on the reel and laterally staggered; the two ends of the iron chain are fixed on the upper fixing shaft and the lower fixing shaft respectively after the iron chain is wound around the reel in an S-shaped manner, and the reel can drive the iron chain to move; and an upper hook is arranged in an upper ring of the iron chain, and a lower chain is arranged in a lower ring of the iron chain. The iron chain is wound around the reel in an S-shaped manner; compared with conventional equipment, the construction height is higher; when a scaffold is required to be lifted higher, all that is required is to repeatedly lift the scaffold, the reel is not required to be carried independently, the iron chain is not required to be inversed and put down, a large number of auxiliary chains cannot be produced, and the construction cannot be influenced.
Description
Technical field
The utility model relates to lifting means, is specifically related to chain type elevator.
Background technology
Endless-chain electric hoist is the plant equipment of transporting by changing potential energy, it is a kind of small lifting equipment, mainly in various lifting applications, also be the normal a kind of lifting means using of attachment type raise scaffold, attachment type raise scaffold is the outer protective scaffold using in highrise building and construction of super highrise building.But existing endless-chain electric hoist, due to design and technical reason, can only unidirectionally promote, lifting false work is in lifting process, need a dead lift motor hoist to fix in the structure of high one deck, support body lifting need to remove motor hoist after putting in place and fixing, the floor that manually motor hoist is transported to higher level is fixed, and carries out the lifting of another scaffold after jack again.In decline process, need a dead lift electric block to fix in the structure of low one deck, support body decline need to remove motor hoist after putting in place and fixing, the floor that manually motor hoist is transported to lower one deck is fixed, and the support body that carries out again another time after jack declines.This operation of motor hoist is not only required great effort, and workman's labour intensity is large, and secondary chain can take segment space, has great potential safety hazard, the continuous dismounting of motor hoist simultaneously, and the equipment of giving has also brought loss.
As the application number utility model that is 201120194572.X, relate to a kind of lifting scaffold hoisting mechanism, it comprises electric block and the wall-attached supporting seat being arranged on main frame of lifting scaffold, the hook of electric block is arranged on upper lift ring, lower suspension hook is arranged on lower lift ring, and main hoisting hook is arranged on side suspension ring, and the guide rail top of main frame of lifting scaffold is fixedly installed assembly pulley, wire rope one end by assembly pulley is connected with hook, and the other end is connected with the movable pulley in counterweight.
Above-mentioned hoisting mechanism; adopt electric block to promote; in the process promoting; the secondary chain producing can take segment space; often can have influence on construction worker's construction, simultaneously because electric block is angled lifting, the stressed of scaffold disperseed; cause in lifting process, need larger power., if need to promote higher distance, need to support by longer chain meanwhile, be unfavorable for the reduction of construction cost.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art, it is a kind of to reach the effect of lifting heavy or rise elevator body by the positive and negative running of motor hoist that the utility model provides, and saves artificial, lifting freely, and this device materials consumption is few, and use cost is low, good stability.
The utility model solves the technical scheme that its technical problem adopts: double hook reversal of the natural order of things endless-chain electric hoist, comprise motor, transmission mechanism, reel and iron chains, reel is arranged on body of wall by wall-attached supporting seat, on reel, being provided with fixed axis and lower fixed axis, staggers in upper fixed axis and lower fixed axis left and right; Iron chains becomes S shape to walk around reel, and iron chains two ends are separately fixed on fixed axis and lower fixed axis, and reel can drive iron chains operation; In the ring of iron chains top, be provided with and rise to the bait, the mouth of hook of rising to the bait, is provided with lower hook in the ring of iron chains below upward; Rise to the bait and lower hook on be provided with the roller that allows iron chains to slide.
In order to prevent that hung article from coming off, described in rise to the bait and/or lower hook on be provided with bayonet lock.
The operating principle of hoisting scaffold: reel is vertically arranged on body of wall by wall-attached supporting seat, rises to the bait and catch on the top of scaffold, lower hook catches on the bottom of scaffold when selecting to catch on position, allows the whole iron chains be tension as far as possible.Remove the fastening devices of scaffold, allow scaffold be fixed by wall-attached supporting seat, starter motor, iron chains is pulled upward, and constantly shorten at the interval between lower hook and reel, upgrades scaffold, the iron chains that below is pulled is pulled to top, rise to the bait and reel between pitch enlargement, in whole process, rise to the bait and lower hook between distance remain unchanged.After lifting puts in place, scaffold is fixed on body of wall.
The operating principle that motor hoist reel promotes voluntarily: owing to rising to the bait and lower hook is fixed on scaffold, put in place when scaffold promotes, scaffold and body of wall are fixed, rises to the bait and lower hook has namely been fixed.Remove fixing between wall-attached supporting seat and body of wall, wall-attached supporting seat is separated with body of wall, and iron chains to be inactive state relatively become the rope that reel climbs, motor reversal, reel upwards climbs along iron chains.
After reel climbs and puts in place, by wall-attached supporting seat, reel is fixed on body of wall again, repeats hoisting scaffold process, so repeatedly, can realize repeatedly climbing of scaffold.The same lifting process of scaffold decline process, as long as required, the rotation direction that changes motor just can realize.
the utlity model has following beneficial effect:1. iron chains is S-shaped is looped around on reel, compares existing equipment, and construction height is higher, promote higher height, as long as repeatedly climb and just can use, does not need to carry separately after reel reversion again and puts down iron chains, can not produce a large amount of secondary chain impacts and construct.
2. rise to the bait and lower hook catches on respectively scaffold up and down, in whole use procedure, iron chains length is certain, and scaffold is more stable in lifting process.After scaffold promotes or has declined, as long as reel is pulled down from body of wall, just can self climbing or decline, do not need this equipment of dismounting again, just can realize the resettlement of lifting drum, minimizing labour intensity, operate more easy, reduction difficulty of construction.
3. this product is mainly used in the construction of engineering construction integral hoisting scaffold, and the handling, road and bridge construction and the equipment that also can be used for processing of stone industry are installed; Can reduce labor intensity, enhance productivity and safety.Product has compact conformation, volume is little, lightweight, efficiency is high, brake feature reliable, easy to use.
