Problems solved by technology

[0002] In general, the balance arm of a large tower crane is a multi-arm structure, and the arm sections are connected by tie rods. When the tie rod is connected to the upper chord of the balance arm arm section, the balance arm tie rod will be installed by a truck crane, which not only increases the cost, but also increases the installation cost. It is laborious and time-consuming, and it is easily affected by the wind, which makes the tie rod shake and is not easy to install; at the same time, it is easy to touch and damage other structures, resulting in safety accidents, and it cannot guarantee the stability of the tie rod during installation.

Abstract

The invention discloses a tower crane balance arm pull rod connecting and mounting device. The tower crane balance arm pull rod connecting and mounting device comprises a tower crane, a moving devicearranged on one side of the tower crane and pull rods connected to one side of the moving device, wherein a tower crane frame is arranged in the tower crane; a motor is arranged on one side of the topof the tower crane frame; a take-up reel is arranged on one side of the motor; a moving block is arranged in the moving device; a pair of connecting lugs is arranged on one side of the moving block;one side of each connecting lug is connected with the corresponding pull rod; a sliding block is arranged on one side of the moving block and slidably connected with the tower crane frame; and the sliding block is connected with the take-up reel through a lifting rope. According to the tower crane balance arm pull rod connecting and mounting device, the arranged motor rotates to drive the liftingrope to pull the moving block to move upwards, and thus the pull rods are driven to be mounted on the tower crane frame; and labor is saved, the mounting efficiency is improved, the resistance of windpower to mounting of the pull rods is reduced, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of tower cranes, in particular to a connection and installation device for a balance arm pull rod of a tower crane. Background technique [0002] In general, the balance arm of a large tower crane is a multi-arm structure, and the arm sections are connected by tie rods. When the tie rod is connected to the upper chord of the balance arm arm section, the balance arm tie rod will be installed by a truck crane, which not only increases the cost, but also increases the installation cost. It is also laborious and troublesome, and is easily affected by the wind, causing the pull rod to shake and not easy to install; at the same time, it is also easy to touch and damage other structures, resulting in safety accidents, and the stability during the installation process of the pull rod cannot be guaranteed. Contents of the invention [0003] The purpose of the present invention is to provide a tower crane balance ar...
