Abstract

The utility model relates to a precast concrete T type roof beam hoisting accessory, characterized by: cutting two L-shaped lifting hooks and an adjustable limiting cross bar by using a steel plate, respectively drilling holes at the top, the neck and the waist of each L-shaped lifting hook, sequentially drilling holes at equal intervals on the adjustable limiting cross bar, enabling hook tips of the two L-shaped lifting hooks to be opposite, enabling the necks to be crossed and overlapped, and penetrating through the neck holes by using bolts to connect to form a scissor-shaped hook frame; determining the distance of an adjustable limiting cross rod according to the width of the T-shaped beam cover plate, aligning the adjustable limiting cross rod hole with two waist holes of the L-shaped lifting hook, and connecting the adjustable limiting cross rod hole with two waist holes of the L-shaped lifting hook through a limiting bolt to form a fixing bayonet; and installing a snap ring at the top hole of the L-shaped lifting hook, penetrating a steel wire rope into the snap ring, moving the lifting device to the gravity center position line of the T-shaped beam from one end of the T-shaped beam, and starting a crane to finish the lifting work of the prefabricated T-shaped beam.

Description

Concrete prefabricated T-shaped beam hoisting device

Technical Field

The utility model relates to a precast concrete T type roof beam hoisting accessory mainly applies to precast concrete component hoist and mount field.

Background

At the precast concrete factory, precast concrete's T type roof beam need the maintenance, transport and dispatch from the factory, prefabricated T type roof beam handling all adopts the mode of binding to go on in the past, often because the component dead weight is too big, the hoist cable is binded and is produced huge self-locking power and can be damaged T type roof beam bight, need fall the position at angle to the unfilled arris when dispatching from the factory and repair, and still need carry out the outward appearance inspection to the defect position after repairing the completion in addition, use such hoist and mount mode extravagant artifical promptly, shorten efficiency again, cost increase.

Disclosure of Invention

The utility model aims at solving the problem that the unfilled edge and the corner can not fall off in the process of lifting the prefabricated T-shaped beam, and the lifting device has simple operation, high efficiency and low cost.

The utility model aims at adopting following mode to realize:

cutting two L-shaped lifting hooks and an adjustable limiting cross bar by using a steel plate, respectively drilling holes at the top, the neck and the waist of each L-shaped lifting hook, sequentially drilling holes at equal intervals on the adjustable limiting cross bar, enabling hook tips of the two L-shaped lifting hooks to be opposite, enabling the necks to be crossed and overlapped, and penetrating through the neck holes by using bolts to connect to form a scissor-shaped hook frame; determining the distance of an adjustable limiting cross rod according to the width of the T-shaped beam cover plate, aligning the adjustable limiting cross rod hole with two waist holes of the L-shaped lifting hook, and penetrating a limiting bolt to form a fixing bayonet; and installing a snap ring at the top hole of the L-shaped lifting hook, penetrating a steel wire rope into the snap ring, moving the lifting device to the gravity center position line of the T-shaped beam from one end of the T-shaped beam, and starting a crane to finish the lifting work of the prefabricated T-shaped beam.

The utility model has the advantages that: by adopting the device, the adjustable limiting cross rod is utilized to enable the lifting device to form the fixed bayonet, the horizontal clamping force of the lifting device is offset, the phenomenon that the prefabricated T-shaped beam is unfilled with corners and falls off in the lifting process can be effectively prevented, the labor intensity of workers is reduced, the production efficiency is improved, and the cost is reduced.

Drawings

Fig. 1 is a usage state diagram of the present invention;

referring to fig. 1, the utility model discloses a include wire rope 1, snap ring 2, connecting bolt 3, spacing bolt 4, adjustable spacing horizontal pole 5, L type lifting hook 6, prefabricated T type roof beam 7.

Detailed Description

Cutting two L-shaped lifting hooks 6 and an adjustable limiting cross rod 5 by using a steel plate, respectively drilling holes at the top, the neck and the waist of each L-shaped lifting hook 6, sequentially drilling holes at equal intervals on the adjustable limiting cross rod 5, then enabling hook tips of the two L-shaped lifting hooks 6 to be opposite, enabling the necks to be crossed and overlapped, penetrating through neck holes by using connecting bolts 3 for connection, and forming a scissor-shaped hook frame; calibrating the distance between the adjustable limiting cross rod holes according to the width of the T-shaped beam cover plate, and connecting the adjustable limiting cross rod holes with the two waist holes of the L-shaped lifting hook through limiting bolts 4 to form a fixing bayonet; and (3) installing a snap ring 2 at the top hole of the L-shaped lifting hook 6, penetrating a steel wire rope 1 into the snap ring 2, moving the lifting device to the gravity center position line of the prefabricated T-shaped beam 7 from one end of the prefabricated T-shaped beam 7, and starting a crane to complete the lifting work of the prefabricated T-shaped beam 7.

Claims

1.
