Construction rope telescopic hook

Abstract

The invention discloses a cable stretching hook for a building. The cable stretching hook comprises a stretchable rod, a barb is arranged at one end of the stretchable rod, a movable handle easily falling from the stretchable rod is arranged at the other end of the stretchable rod, and a supporting frame facilitating rotation of the stretchable rod is arranged at the bottom of the stretchable rod;and the stretchable rod is provided with a first rod section, a second rod section and a third rod section, the end of the first rod section is provided with a first driving motor for driving the barb to rotate, a positioning light source is arranged at the upper end of the first rod section, the second rod section is located between the first rod section and the third rod section, the third rodsection is provided with a second driving motor for driving the barb to achieve hook lifting or hook falling and an assistant positioning mirror, a first electric air cylinder and a second electric air cylinder for driving the first rod section and the second rod section to stretch out or draw back are arranged inside the third rod section, and a lithium battery and a plurality of control buttonsare arranged at the tail end of the third rod section. According to the cable stretching hook, a tower crane steel rope is locked with high accuracy, the visibility at night is good, the high altitudefalling accident rate is reduced, and the positioning guide and power traction stability is good.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a telescoping hook for a construction rope. Background technique [0002] At present, there are a lot of high-rise buildings. Taking residential commercial housing as an example, commercial housing is divided into low-rise, small high-rise and high-rise according to the height of the floor. For low-rise buildings, the concrete, bricks and other building materials used in the construction are basically transported to the built floors by hand. Most of the small high-rise and high-rise commercial buildings are moved by tower cranes. A steel rope is provided on the tower crane, and a spring hook is provided at the lower end of the steel rope. The construction materials are placed in the bucket box, and the bucket box is hooked with the spring hook, and the tower crane begins to pull up and move to the built floor. However, during the moving process of the tower crane,...

AI Technical Summary

Problems solved by technology

[0004] 1. The tower crane cannot accurately stretch and move building materials to the target building position. Outside the range of the arm, the construction worker needs to guide the tower crane to move to the target position, lacking positioning guidance and power traction equipment;

[0005] 2. The torque of the tower crane is relatively large. Within the range of the arm, the construction worker manually pulls the steel rope of the tower crane. Once the torque of the tower crane turns, the construction worker manually releases it in time, which is prone to high-altitude falling accidents;

[0006] 3. The torque of the tower crane is relatively large, and the pulling force of the steel rope is large. Although the construction workers can reach the steel rope within the arm range, they cannot pull the steel rope.
