Description

A new type of modular attachment frame for tower crane

technical field

The invention designs a novel modular attachment frame for a tower crane, which belongs to the technical field of crane mechanical equipment in building construction.

Background technique

Tower cranes are the most common construction hoisting machinery in construction. They are mainly responsible for vertical transportation of materials and horizontal hoisting and transportation of materials in construction projects. It is very common for the height of the tower crane to be over 100 meters. When the height of the tower crane exceeds the independent height, an attachment frame must be used to connect the tower body with the building, which can reduce the free height of the tower body, thereby reducing the internal force of the tower body and achieving maintenance The overall stability of the tower crane and the purpose of improving the lifting capacity. The attachment and foundation of the tower crane are like the "hands" and "feet" of the tower crane, which maintain the safety of the tower crane. Only the "feet" are firmly held firmly, and the "hands" are firmly held, so that the tower crane can stand firmly , there is safety at all. Therefore, whether the design and manufacture of the attachment frame of the tower crane is correct and reasonable directly affects the safety of the whole machine.

Contents of the invention

In view of the above problems, the purpose of the present invention is to provide a new modular attachment frame for tower cranes with simple structure, simple operation, low cost, high reliability and stability.

In order to achieve the above object, the technical solution adopted by the present invention is: a new type of modular attachment frame for tower cranes, the whole device consists of four parts: ear socket, adjustment device, modular attachment rod, and modular attachment frame. The ear seat has a pair, which is divided into a single ear seat and a double ear seat, and is connected with the building with high-strength bolts. The adjustment device is a threaded structure, which is threadedly connected with the attachment rod, and is used for adjusting the length within 100mm. The modular attachment rod is composed of a joint rod, an intermediate connecting rod and a connecting block rod. The modular attachment rod is threadedly connected to the adjustment device and the modular attachment frame, and the joint rod, the intermediate connecting rod and the connecting block rod are passed through Pin connection. The modular attachment frame and the tower body are fixed by bolts, and the two inner struts are also connected by bolts to the main chord of the tower body.

The ear seat is welded on a thick steel plate, and there are six threaded holes on the steel plate, which are connected with the wall by high-strength bolts.

The adjustment device is composed of an adjustment screw and a joint, and is connected with the connecting block rod of the modular attachment rod through the joint for adjusting the length within 100mm.

Said modularized attachment frame, the attachment frame is sleeved on the tower body, fastened to the tower body with bolts, and pre-tightened by bolt connection with the four main chords of the tower body through two inner struts.

The invention has simple structure, low cost, is beneficial to standard-attached production management, simple operation, reduces repetitive work, improves personnel working efficiency, and improves construction efficiency.

Reasonable structural layout, convenient for popularization and practicality; high reliability and stability.
