Description

A device for removing wall-attached tie rods of high-altitude tower cranes

technical field

The utility model relates to the field of large-scale engineering machinery, in particular to a device for removing a wall-attached tie rod of a high-altitude tower crane.

Background technique

With the gradual maturity of domestic high-rise building construction, tower cranes, as an indispensable construction equipment for high-rise and super high-rise buildings, play a pivotal role in building construction. The external tower cranes can be increased with the increase of building construction height. With the increase of the floor, the mechanical equipment can be jacked up after installing the wall-attached link system connected with the building structure. This type of equipment is widely used in high-rise building construction. Due to its design, the tower crane usually has a range of amplitude from 0m to the maximum range, but it cannot be hoisted at the balance arm (the balance arm is negative range). Before the main body of the building is capped, the tower crane can freely rotate 360 degrees because the height has always exceeded the height of the building, so there is no problem of hoisting difficulties in the construction of the wall-attached rod system. The crane is close to the building. At this time, the tower crane cannot move, and can only descend from the direction the boom is pointing. Therefore, it is difficult to remove the wall-attached rod at the balance arm at this time. Generally, the demolition workers use small hoisting hoists and wire ropes to remove it. Once the angle is unfavorable or the wall-attached rod is long, the conventional removal method appears to be stretched. If the lifting wire rope in the direction of the main hook is still used for the demolition operation, it must be tilted and tilted. This operation method violates the safety regulations in the "Ten Do Not Lift" of tower cranes. It is very easy to cause injury, and what is more, an accident of injury occurs. The removal of the wall-attached tie rods of the external tower crane is an important step in the removal of the lower section of the tower crane. The safety and progress of its removal are directly related to the progress of the subsequent removal of the tower crane.

At the same time, by adjusting the position of the fixed wire rope, the The demolition pole is well applied in the application of the demolition work of the wall-attached rods at different positions. At the same time, the application of fixing high-strength bolts can meet the connection requirements of structural beams or floors of different thicknesses. All structural parts can be used after use. After dismantling and reinstalling, the equipment can be recycled without loss. This device can have good and universal applicability on the basis of ensuring construction safety, and can reduce construction period consumption and avoid accident losses. It is worthy of vigorous promotion.
