Embodiment Construction

[0022] The structure of the equipment group for replacing the faulty motor parts of the high-altitude operation tower crane according to the present invention will be described in conjunction with the accompanying drawings.

[0023] 1. Description of the components that make up the equipment group

[0024] Such as figure 1 , 2 , 3, the present invention is used to replace the equipment set of the faulty motor parts of the aerial work tower crane, the equipment set includes a triangular bracket 2, and the triangular bracket 2 is fixed on the balance arm of the tower crane. One side of the tower crane is fixed with a hoist 1, and the hoist 1 includes a motor 3, a reducer 4, a rope winding part 5, a steel wire rope 6, a base 7, and a counterweight 8, and the hoist is fixed on the ground through the counterweight 8. The hoist 1 provides power, and the triangular support 2 is used as an auxiliary support facility, which can realize hoisting the motor of the tower crane to the gro...

Abstract

The invention provides a device group for replacing a malfunctioning motor part of an aerial work tower crane. A triangle bracket of the device group is fixed to a balance arm of the tower crane. A winding engine is fixed on the ground at one side of the tower crane. The winding engine is connected with the triangle bracket on the balance arm of the tower crane through a steel wire rope. The device group contains the triangle bracket which is fixed to the balance arm of the tower crane with bolts through an Omega-shaped fixed jaw. The invention has the following effect: each component of the triangle bracket of the device is assembled through bolts and is convenient to detach and transport. It is convenient and fast to assemble the triangle bracket on a work platform, and stable operation can be guaranteed. The triangle bracket can be positioned in both horizontal and vertical directions, and the rotation axis can rotate 360 degrees. Each component of the device can be flexibly assembled and disassembled at the construction field and can be repetitively used in many projects.

Description

technical field [0001] In construction engineering, tower crane is the most critical mechanical equipment for vertical and horizontal transportation. If the motor components of the tower crane fail, the damaged motor needs to be replaced. The present invention relates to an equipment set for replacing motor parts that have failed in a high-altitude operation tower crane. Because the weight of the motor part of the tower crane is relatively large, the weight of the motor part of the general tower crane is between 350 and 500 kg, and it is difficult to replace the motor due to the high-altitude operation. larger. Background technique [0002] In construction engineering, the tower crane is the most critical mechanical equipment for vertical and horizontal transportation. The motor part of the tower crane works in an open-air environment, which is prone to failure. Tower cranes are working at high altitudes, and maintenance is difficult, and new motors are often replaced. ...
