Description

A kind of hoist engine hanging method of small space inner structure
Technical field
The present invention relates to structure hoisting, more particularly to a kind of structure hoisting method of utilization hoist engine.
Background technology
At present, with the quickening of industrial process, increasing old factory building need to be transformed, but old old factory rehabilitation place is narrow Small, structural member needs to carry out to get to Hoisting Position using crane Secondary Transport mostly, and large lifting equipment, structural member can not Operation area is directly entered, material lifting need to be carried out using hoist engine or is put down to drag installation.Traditional construction method is in narrow field In the case of, a component will often be had bad luck back and forth can just be transported to installation site several times, and be needed when being lifted using hoist engine Want continuous traveling hoisting machine, but hoist engine its own heavier-weight, movement gets up to need crane to coordinate, inconvenient;Also Having hoist engine, often there is overlapping, crossing in steel wire rope in use, forms potential safety hazard.This method not only lost labor Machine cost, and often because control occurs not in time, steel wire rope is overlapping, crossing, influence lifting speed.
The content of the invention
It is contemplated that overcoming the defect of prior art, there is provided a kind of hoist engine hanging method of small space inner structure. The problems such as present invention efficiently solves small space component ground spelling, has bad luck, lifts.Hoist engine horizontal shift is also solved to be stranded It is difficult, it is to avoid steel wire rope is overlapping in hoist engine work, crossing, torsion be around can not only increase service life of steel wire rope, more improve Lift speed.
In order to solve the above-mentioned technical problem, a kind of hoist engine hanging method of small space inner structure, it includes following step Suddenly:
Step one, according to construction deployment and live place situation, component landline is planned;
Step 2, sets heavy steel member ground to have bad luck fixture;Fixture is had bad luck on the ground to be included being connected by a connecting rod Two channel-section steels together, two channel-section steel openings are set in the same direction, and its two ends that are open is each provided with a wheel clamp, two grooves The outside of steel back face two is each provided with block that is vertical, preventing steel member from moving left and right;
Step 3, has bad luck on ground and structure assembly is carried out on fixture;
Step 4, Hoisting Position is drawn to using hoist engine by component;
Step 5, irregular unit body carries out centre of gravity adjustment;
Step 6, lifting is in place;
Step 7, sets hoist engine auxiliary hoisting device;The auxiliary hoisting device includes base dolly, power supply box and elevator Machine is placed on base dolly, and dolly rear end sets bearing pin and is connected with earth anchor, and the dolly side in steel wire rope of windlass lead is set Have guide rod, guide rod is connected using bearing pin with base, and can above and below, swing, be oriented to rod end be provided with leading block;It is provided with The dolly side of guide rod side is provided with position block;
Step 8, small members lifting is carried out using hoist engine;
Step 9, adjustment welding completes structure hoisting.
The hoist engine hanging method of described small space inner structure, the step 8 includes:
Before lifting operation, the hoist engine of selection is fixed on dolly, three-level distribution box power supply is connected, dolly can utilize steel Cord is connected with earth anchor or structure;
According to lifting drum size, position block is adjusted, guide rod is swung amplitude control in wirerope-winding In pitch;
Lifting steel wire rope is connected along guide rod direction by leading block with playing heavy object;
During lifting, lifting drum rotates and tightens up steel wire rope, and now guide rod and roll-shaped are at a certain angle, once The angle of guide rod and reel is constant in hoisting process.The fixed pulley for being oriented to boom end plays the work for changing steel wire rope Impact direction With;
With the rotation of reel, the steel wire rope on reel leads lower marshalling in guide rod.
Fixture is had bad luck on the ground that the present invention is used, and completes small space component assembly, has bad luck work, saves large scale computer Tool takes, it is to avoid the destruction painted to steel member surface, it is ensured that the impression quality of finished product steel member.Hoist engine auxiliary hoisting device system Make simple, horizontal shift is convenient, it is not necessary to the cooperation of large lifting equipment;The design of guide rod and leading block, can be effective Control steel wire rope individual layer and multilayer crossing, turn round around playing a protective role.The design of hoist engine moving cart efficiently solves elevator Machine horizontal range is moved, and guide rod is cleverly designed with being oriented to fixed pulley, steel wire rope is hung down all the time with reel in the course of the work It is straight tangent, so as to serve the effect of protection steel wire rope.The present invention efficiently solve small space component ground spelling, have bad luck, The problems such as lifting.Also solve hoist engine horizontal shift difficult, it is to avoid steel wire rope is overlapping in hoist engine work, crossing, torsion around, Service life of steel wire rope can not only be increased, lifting speed is more improved.
