Description

Balance hoisting frame for large sheet structure

Technical Field

The utility model belongs to the technical field of hoist and mount haulage equipment, concretely relates to balanced hoist and mount frame for large-scale sheet structure.

Background

In petrochemical engineering construction, in order to shorten the construction period, a plurality of large-scale equipment increase the factory prefabrication depth, the large-scale equipment enters the field in the form of semi-finished components, after the semi-finished components are folded by experience, the large-scale sheet structures are assembled on the field, and the integral hoisting construction process of a large crane is adopted. Therefore, under the condition, the balance beam is simple, practical, safe and reliable, and the problem of equipment hoisting under the construction condition is solved.

Disclosure of Invention

The utility model aims at providing a can effectively improve hoist and mount construction work efficiency, make hoist and mount construction safer sheet structure's balanced hoist and mount frame.

The utility model adopts the technical proposal that:

the utility model provides a balanced hoist and mount frame for large-scale lamellar structure, includes compensating beam, its characterized in that: the bottom surface is equipped with the lug on the compensating beam, be equipped with the lifting rope on going up the lug, go up the lifting rope interlude on last single round fixed tackle, the bottom surface is equipped with down the lug under the compensating beam, it has lower single round fixed tackle to have articulated on the lug down, it has lower lifting rope to interlude on the lower single round fixed tackle, be equipped with the guy rope on the lower single round fixed tackle.

Preferably, the angle α between the equalizer beam and the upper hoist rope is 60 °.

Preferably, the balance beam is of an H structure.

Preferably, the number of the upper lifting lugs is two, and the two upper lifting lugs are distributed on the upper bottom surface of the balance beam.

Preferably, the number of the lower lifting lugs is nine, and the lower lifting lugs are uniformly distributed on the lower bottom surface of the balance beam.

Preferably, the number of the guy cables is two, and the guy cables are distributed at two ends of the balance beam.

The utility model has the advantages that: the balance beam has the advantages of simple structure, convenience in operation, safety and reliability, solves the difficult problem of hoisting of the sheet structure, is simple to manufacture, clear in stress analysis, feasible in technology, safe and reliable, reduces aerial operation due to the adoption of ground assembly, better controls the installation quality and shortens the construction period.

1. The upper lifting lug is two pieces of balance for keeping the lifted equipment, and the sling is prevented from damaging the equipment.

2. The lower lifting lug is nine even fixed connections below the compensating beam, reduces the horizontal pressure that bears when equipment lifts by crane, avoids damaging equipment.

Detailed Description

The present invention will be described in detail with reference to the following embodiments:

1-4 a balanced hoist and mount frame for large-scale lamellar structure, including compensating beam 4, the welding of compensating beam 4 top surface has two to go up lug 3, upward wear to be equipped with lifting rope 2 on lug 3, go up lifting rope 2 and wear on last singly deciding coaster 1, and go up lug 2 and compensating beam one-tenth interior 60 contained angles, the welding of compensating beam 4 bottom surface has nine lugs 5 down, it has nine single round fixed coasters 6 down to hang on lug 5 down, lower lifting rope 7 wears to establish under on single round fixed coaster 6, be connected with cable wind rope 8 on the single round fixed coaster 6 down.

The materials are selected as follows: the balance beam is H-shaped, the specification is 250 multiplied by 9 multiplied by 14, the length L =18400mm, the number is 1,

the upper lifting lug 3 is made in the field with the diameter delta =14mm and is made of the same material as the H-shaped steel; the lower lifting lug 5 is manufactured on site by delta =10mm and is made of the same material as the H-shaped steel;

the model of the upper single-wheel fixed pulley 1 is HQLK1-2, is the same as that of the H-shaped steel, and is the same as that of the lower single-wheel fixed pulley 6;

the model of the upper lifting rope 2 is 6 multiplied by 37 plus FC phi 28mm L =20000mm, and the specification is the same as that of the 7 model of nine lower lifting ropes;

the lower lifting lug 5 is 6 multiplied by 37+ FC phi 16mm L =20000 mm.

The working principle is as follows: after the large-scale sheet-shaped structural parts are assembled, the large-scale sheet-shaped structural parts are flatly placed in a prefabricated yard, a large-scale crane lifts a balance beam of the large-scale sheet-shaped structure, an upper lifting rope drives the sheet-shaped object to slowly lift, meanwhile, a cable wind rope is manually controlled by a member not to rotate, the horizontal state of the equipment is changed into the vertical state along with the gradual increase of the lifting angle of the equipment, and the object can automatically find a balance point through the upper lifting rope penetrating through an upper single-wheel fixed pulley in the lifting process until the object is in the vertical state due to the influence of self; the 2 main hoisting points arranged on each stand column are uniformly stressed all the time, the hoisting points are balanced, the hoisting process is stable and smooth, after the equipment is stable in a vertical state, the large crane is rotated to drop the sheet object to the foundation in place, and after the object is in place, the wind cable is used for adjusting the verticality of the position of the sheet object.
