Safety cat ladder for building tower crane

Abstract

The invention discloses a safety cat ladder for a building tower crane, and belongs to the field of lifting devices. The technical scheme of the safety cat ladder is characterized by comprising a machine body, a connecting end and a gravity block, wherein the gravity block is connected in the machine body in a penetrating manner, the gravity block is arranged at the center of the machine body, four bending claws are connected to the periphery of the outer wall of the machine body in a penetrating manner, and the lower end of each bending claw is fixedly connected with a rubber foot pad througha bolt. The stability of the lifting device can be effectively improved, the problem that the lifting device needs to be moved repeatedly to meet the requirements of transporting a building workpiecein a multi-direction manner is solved, the use convenience of the lifting device is effectively improved, the problem that the machine body is prone to axially sliding is solved, the lifting qualityis effectively improved, the placement friction force of the building workpiece can be increased, the problem that the building workpiece is prone to slide is solved, the stability of bearing the workpiece is effectively improved, the problem of safety accidents caused by easily falling of a placing plate is avoided, and the safety of the lifting device is effectively improved.

Description

technical field [0001] The invention relates to the medical field, in particular to a safety ladder for building tower cranes. Background technique [0002] The construction tower crane safety ladder is a device that lifts construction workpieces in the vertical direction. It can transport construction workpieces in the vertical direction by lifting and lowering the lifting shaft, thereby effectively reducing the trouble of manual handling. However, the lifting device The stability of the machine is poor, and the lifting device needs to be moved repeatedly, the stability of the workpiece is poor, and the placement plate is easy to fall and cause a safety accident. [0003] A current building lifting device, but the stability of the lifting device is poor, including a bearing plate, a group of No. 1 circular grooves are processed on the upper surface of the bearing plate, and telescopic ends are provided on the inner and lower surfaces of a group of No. 1 circular grooves.

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a safety ladder for building tower cranes, which solves the problem that the lifting device is prone to displacement, effectively improves the stability of the lifting device, and solves the problem of repeatedly moving the lifting device. It satisfies the problem of multi-directional transportation of construction workpieces, effectively improves the convenience of using the lifting device, solves the problem that the body is prone to axial sliding, effectively improves the quality of lifting, and can increase the friction of placing construction workpieces. It solves the problem that the construction workpiece is easy to slide, effectively improves the stability of the workpiece, avoids the problem of safety accidents caused by the easy fall of the placement plate, and effectively improves the safety of the lifting device
