technical field

The invention relates to the technical field of tower tube hoisting equipment, in particular to a tower tube hoisting tool.

Background technique

As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×10 ⁹ MW, of which the usable wind energy is 2×10 ⁷ MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. China's wind energy reserves are large and widely distributed. The wind energy reserves on land alone are about 253 million kilowatts. In 2015, my country's new installed capacity was 30,500 MW, accounting for 48.4% of the global new increase, and the total installed capacity of wind turbines in my country reached 145,000 MW. In theory, about 100 million tons of towers are needed for support. In the process of tower tube production, it is necessary to transport and hoist the finished and semi-finished tower tubes. The weight of each tower tube is generally about 15-40 tons. The traditional hoisting method is to use slings at the two ends of the tower tube at a distance of 200-400mm from the flange. Hoisting, during the hoisting process, because the sling will exert huge pressure on the paint surface and the sling will be elongated, causing damage to the paint on the surface of the tower tube. Before the next paint is sprayed or the product leaves the factory, personnel are arranged to repair the damaged paint surface. It consumes man-hours, wastes paint, and the effect of touch-up paint is very poor compared with the original paint surface. In addition, the use of slings for hoisting requires two cranes to lift at the same time. When the slings are hoisted, if they are not perpendicular to the tower or do not cooperate tacitly, the danger of the slings slipping will easily occur, and the consequences will be disastrous.

Contents of the invention

The invention solves the deficiencies of the prior art and provides a hoisting tool for tower tube hoisting that saves labor and time, is safe for hoisting, and does not damage the paint surface.

The technical scheme that the present invention solves its technical problem adopts is:

A tower hanger includes a hook and a hanging rope; a groove is provided on the hook, and a support reinforcement plate is arranged in the groove.

A support buffer pad is provided on the support reinforcement plate.

It also includes a U-shaped snap ring, a pin hole is provided on the U-shaped snap ring and the suspension hook, the pin shaft passes through the U-shaped snap ring and the pin hole of the suspension hook, and the U-shaped snap ring is connected with the suspension rope.

The width of the support reinforcement plate is greater than the width of the hook.

The support reinforcement board is an arc board.

An anti-off hook is arranged on the hook, and the shape of the hook is G type.

A buffer pad is arranged inside the hook.

The cushion pad is made of rubber.

The material of the supporting buffer pad is rubber.

Both sides of the hook are symmetrically provided with supporting reinforcement plates.

The beneficial effects of the present invention are:

1. A tower hanger, including a hook and a sling. A groove is provided on the hook, and a support reinforcement plate is provided in the groove. When lifting, the support reinforcement plate is attached to the flange plate, and the sling is no longer used for binding The tower tube will not cause damage to the tower tube body. A support buffer pad is provided on the support reinforcement plate. Reduce the impact of the support reinforcement plate on the flange during lifting.

2. The spreader for hoisting the tower also includes a U-shaped snap ring. A pin hole is set on the U-shaped snap ring and the hook. The pin shaft passes through the pin hole of the U-shaped snap ring and the hook. The U-shaped snap ring and the lifting rope connect. The U-shaped snap ring and sling type can be adjusted according to the hoisting weight. The width of the support reinforcement plate is greater than the width of the hook, and the support reinforcement plates are arranged symmetrically on both sides of the hook, so as to improve the support strength of the support reinforcement plate and make the hoisting more stable. The support reinforcement board is an arc-shaped board. Increase the bonding area between the support reinforcement plate and the tower tube.

3. An anti-off hook is set on the hook, and the shape of the hook is G type. Prevent decoupling during lifting and improve equipment safety. The inner side of the hook is provided with a buffer pad to prevent the hook from scratching the wall of the tower tube.

To sum up, the present invention reduces the damage to the flange, the hook is convenient, the painted surface is not lost after the tower is hoisted, painting is no longer required, and manpower and material costs are greatly saved. The equipment no longer uses slings and the slings are not easy to damage, which can reduce the amount of slings and save production costs.
