A kind of small-size hoisting machine be fixed on channel-section steel framework
Technical field:
The present invention relates to a kind of small-size hoisting machine be fixed on channel-section steel framework, be widely used in being fixed on upper and lower hanging device on channel-section steel framework, belong to substation equipment maintenance and repair site technology field.
Background technology:
Along with the development of electrical network intellectuality, automation, substation's enlarging, transformation and handling labor are increasing.In substation's enlarging, improvement project construction, need carrying, the larger equipment of a large amount of weight is installed, and it is all be fixed on the framework of high-altitude that these equipment have greatly, as the installation of the equipment such as current transformer, voltage transformer, need to carry out lifting operation, but be much mounted in indoor because above equipment has, narrow space, lack the restriction of the condition such as the strong point, cannot use big machinery, task difficulty is large.The mode of traditional operation is that manual chain hoist is hung on the firmly strong point, or at indoor setting support, the equipment hung on by jack on support lifts through row.This mode not only expends time in, waste of manpower, and there is certain security risk, easily causes safety misadventure.
Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of structure simple, easy to make, applied widely, save labour, save time, reduce labour intensity, raise the efficiency, safety factor is high, the small-size hoisting machine that what cost of manufacture was low be fixed on channel-section steel framework.
Object of the present invention can be reached by following measure: a kind of small-size hoisting machine be fixed on channel-section steel framework, it is characterized in that it comprises the lower iron plate in bottom, iron plate on bottom, bottom is descended on iron plate and bottom and iron plate is respectively equipped with corresponding bolt connecting hole, iron plate connects lower pillar stand in bottom, the both sides of lower pillar stand and bottom connect two pieces of iron plates between iron plate, the lower end of upper pillar stand is inserted in lower pillar stand, the upper end of upper pillar stand is connected with horizon bar and brace, the first strut bar is connected between upper pillar stand and horizon bar, the second strut bar is connected between upper pillar stand and brace, the 3rd strut bar is connected between horizon bar and brace, the upper end of brace connects pulley, small-sized electric cucurbit is connected under horizon bar, one end of connecting steel wire ropes on small-sized electric cucurbit, steel wire penetrating pulley, steel cord ends connecting shackle.
The present invention can produce following good effect compared with the prior art: the present invention can be fixed on channel-section steel framework, controlled the lifting of upper and lower equipment by the controller of small-sized electric cucurbit, avoid potential safety hazard, can labour be saved, save time, reduce labour intensity.It has:
1. structure is simple, easy to make.Bottom is fixed on channel-section steel framework a long way off by the upper and lower hanging device of controller.
2. applied widely.Be applicable to the upper and lower hanging device of all channel-section steel frameworks.
3. overhaul efficiency is high.Can safety be ensured, reduce test period, save labour, reduce labour intensity.
4. cost of manufacture is low.This dolly can be applicable to the upper and lower haulage equipment of channel-section steel framework, has promotional value.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention: the specific embodiment of the present invention is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of small-size hoisting machine (see Fig. 1) be fixed on channel-section steel framework, it comprises the lower iron plate 1 in bottom, iron plate 2 on bottom, bottom is descended on iron plate 1 and bottom and iron plate 2 is respectively equipped with corresponding bolt connecting hole 15, iron plate 2 is welded with lower pillar stand 4 in bottom, two pieces of iron plates 3 are welded on the upper iron plate 2 in bottom and lower pillar stand 4 reinforces its weight capacity, the lower end of upper pillar stand 14 is inserted in lower pillar stand 4, the upper end of upper pillar stand 14 is welded with horizon bar 7 and brace 13, the first strut bar 5 is welded with to add stiff stability between upper pillar stand 14 and horizon bar 7, the second strut bar 12 is welded with to add stiff stability between upper pillar stand 14 and brace 13, the 3rd strut bar 8 is welded with to add stiff stability between horizon bar 7 and brace 13, pulley 10 is equipped with in brace 13 upper end, horizon bar 7 fixes small-sized electric cucurbit 6, one end of connecting steel wire ropes 9 on small-sized electric cucurbit 6, steel rope 9 is through pulley 10 end connecting shackle 11.
During hanging device, being bolted hole, hole 15 with two cover bolts is fixed on channel-section steel framework by iron plate 1 under iron plate on bottom 2 and bottom, upper pillar stand 14 is inserted in lower pillar stand 4, equipment hoisting is on suspension hook 11, the position of suspension hook 11 is adjusted by rotating upper pillar stand 14, lifted up and down by the controller control convenience of small-sized electric cucurbit 6, reach saving labour power, improve the object of safety.
