Description

A new type of soft attachment device for tower cranes

technical field

The utility model relates to the technical field of tower cranes, in particular to a novel soft attachment device for tower cranes.

Background technique

Wire rope soft attachment is a tower crane attachment form suitable for structural construction such as cooling towers. Generally, cooling towers have a large diameter and a hyperbolic shape. In order to save mechanical costs, tower cranes are generally arranged near the middle of the cooling tower. As a result, the tower crane is far away from the outer wall of the cooling tower (about 40m or more), and conventional attachment cannot be realized.

Contents of the invention

The utility model aims at solving the above problems, and provides a novel soft attachment device for a tower crane.

In order to overcome the defects in the background technology, the technical solution adopted by the utility model to solve the technical problem is: a new type of soft attachment device for a tower crane, including a module ear seat, a shackle and a pre-installation device installed in the cooling tower wall. Embedded parts, embedded parts include special vertebral bodies, first high-strength bolts and embedded plates, one end of the embedded plate and the first high-strength bolts is fixed by welding, and the other end of the first high-strength bolts is sleeved with a special vertebral body , the module ear seat is connected to the special vertebral body through the second high-strength bolt, the shackle is fixed on the module ear seat through the third high-strength bolt, and the shackle can pass through the wire rope.

In a preferred embodiment of the present invention, the special vertebral body is a hollow structure, and the hollow part is provided with threads matching the first high-strength bolt and the second high-strength bolt, and the first high-strength bolt is screwed into the special vertebral body At one end of the vertebral body, the second high-strength bolt is screwed into the hollow structure at the other end of the special vertebral body.

In a preferred embodiment of the present utility model, the special vertebral body is cylindrical or inverted conical with a large top and a small bottom.

The beneficial effects of the utility model are: the device has a simple structure, is convenient to install and disassemble, and saves time and effort. Since the wall of the cooling tower is thin, the unit area cannot bear excessive tension, so the attachment adopts multi-layer and multi-point anchoring methods to wear around Soft attached wire rope. After use, the steel wire rope, the wall end shackle, the third high-strength bolt, the module lug seat and the second high-strength bolt can all be recycled to save resources.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

detailed description

As shown in Figures 1 to 3, a new type of soft attachment device for tower cranes includes module lugs 1, shackles 2 and embedded parts arranged in the wall of the cooling tower. The embedded parts include special vertebral body 3, the first A high-strength bolt 41 and a pre-embedded plate 5, one end of the pre-embedded plate 5 and the first high-strength bolt 41 are fixed by welding, and the other end of the first high-strength bolt 41 is provided with a special vertebral body 3, after the concrete strength meets the attachment requirements The module lug 1 is connected to the special vertebral body 3 through the second high-strength bolt 42, the shackle is fixed on the module lug 1 through the third high-strength bolt 43, and the shackle 2 can be used for the wire rope to pass through.

The special vertebral body 3 is a hollow structure, and the hollow is provided with threads matching the first high-strength bolt 41 and the second high-strength bolt 42, the first high-strength bolt 41 is screwed into 3 one ends of the special vertebral body, and the second high-strength bolt 42 is screwed into Into the hollow structure at the other end of the special vertebral body 3, through the above method, the installation between the special vertebral body and the first high-strength bolt and the second high-strength bolt is convenient, saving time and effort.

The specially made vertebral body 3 is cylindrical or inverted conical with a large upper part and a smaller lower part. It has a simple structure and is convenient for pre-embedding and installation.

The device has simple structure, convenient installation and disassembly, and saves time and effort. After use, the steel wire rope, wall end shackle, third high-strength bolt, module lug seat and second high-strength bolt can all be recycled to save resources.

It should be emphasized that: the above is only an embodiment of the utility model, and is not therefore limiting the patent scope of the utility model. Any equivalent structure or equivalent flow conversion made by using the specification of the utility model and the contents of the accompanying drawings, or directly Or indirectly used in other relevant technical fields, all are included in the patent protection scope of the present utility model in the same way.
