Problems solved by technology

Such a scheme has many shortcomings: 1. The safety factor is not high, such as turning over before welding is easy to cause deformation of components
2. It will cause great damage to the base metal. 3. After the component is qualified and before shipment, the hoist must be removed, resulting in a lot of labor

Embodiment Construction

[0024] see figure 1 , the structural form of the oversized cross-section box-shaped member turning over spreader in this embodiment is: a "mouth"-shaped spreader is composed of an upper pole 1, a lower pole 2, and two left and right auxiliary poles 3; wherein, the upper pole 1, the lower pole The shoulder pole 2 is connected with the left and right auxiliary poles 3 through the pin shaft 6 and the pin shaft cap 7; the two ends of the upper pole 1 are respectively provided with the upper pole lifting holes 1a, and the two ends of the lower pole 2 are respectively provided with the lower pole Lifting hole 2a.

[0025] In specific implementation, the auxiliary shoulder pole 3 is composed of two splints 4 and a reinforcement 5 arranged between the two splints 4, and the splint 4 and the reinforcement 5 are welded as a whole; The shoulder pole 2 is clamped, and the structure of this splint makes the production of the auxiliary pole 3 more convenient. If a whole piece of steel plat...

Abstract

The invention discloses a box-type member turn-over lifting appliance with an oversized cross section and an application method thereof. The box-type member turn-over lifting appliance is characterized in that a mouth-shaped lifting appliance is formed by an upper shoulder pole, a lower shoulder pole, a left auxiliary shoulder pole and a right auxiliary shoulder pole, wherein the upper and lower shoulder poles are connected with the left and right auxiliary shoulder poles through a pin shaft and a pin shaft cap; upper shoulder pole lifting holes are respectively arranged at both ends of the upper shoulder pole; and lower shoulder pole lifting holes are respectively arranged at both ends of the lower shoulder pole. The lifting appliance is safe and convenient to use, is detachable, and can effectively prevent members from deforming.

Description

technical field [0001] The invention relates to a hoist and a using method thereof, more specifically to a turning hoist applied to a super-large cross-section box-shaped steel structure and a using method thereof. Background technique [0002] In the process of steel structure fabrication, when turning over a super-large box-shaped member, it is usually necessary to install a turning hoist. The specific installation position is to install two on both sides of the longitudinal surface of the box-shaped member, and weld them firmly. When turning over, hang two steel wire ropes with the big and small hooks of the vehicle, and lock them on the suspension horse with a shackle to turn over in the air. Such a scheme has several deficiencies: 1. The safety factor is not high, such as turning over before welding is easy to cause deformation of components. 2. It will cause great damage to the base metal. 3. After the component is qualified and before shipment, the hoisting horse mus...
