Parallel-type spline falling-prevention device and application method thereof

Abstract

The invention provides a parallel-type spline falling-prevention device and an application method thereof. According to the parallel-type spline falling-prevention device, a movable force bearing device can drive rotation wedge blocks to be clamped into tooth grooves of a guide frame spline, the rotation wedge blocks have driving force for making the rotation wedge blocks rotate anticlockwise, andclamp blocks limit continuous anticlockwise rotation of the rotation wedge blocks when the rotation wedge blocks anticlockwise rotate to horizontal positions; when clamped into the tooth grooves of the guide frame spline respectively, the rotation wedge blocks can move upwards relative to the guide frame spline, the clamp blocks can prevent the rotation wedge blocks from moving downwards relativeto the guide frame spline, bite force between the rotation wedge blocks and the guide frame spline can provide high bearing capability, a falling prevention effect is achieved in a climbing stage ofa guide frame climbing working platform, operation safety of mechanical equipment is ensured, and the problems are solved that in a prefabricated building major structure construction stage of the guide frame climbing working platform, due to long-term electromagnetic braking of a motor, sufficient braking force can be caused, and a current locking device is high in manual intervention degree andlow in accuracy.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, and relates to a safety anti-drop device for rack and pinion climbing mechanical equipment. Background technique [0002] The guide frame climbing working platform is a kind of aerial work platform that is driven by a motor and adopts a rack and pinion method to climb. It is mainly used for maintenance, renovation, decoration and other construction operations of buildings and structures. Driven by my country's key strategy of accelerating the industrialization of construction, new prefabricated buildings have developed rapidly, and new prefabricated construction projects are increasing. More and more applications in prefabricated building construction. [0003] In the construction process of the prefabricated building, the guide frame climbing working platform mainly has two application stages: main structure construction and wall decoration. [0004] During the construction sta...

Problems solved by technology

[0007] The purpose of the present invention is to provide a row-type rack anti-falling device, which can fix the equipment through the engagement of the device and the rack when it stays at high altitude, which can provide a large load-bearing capacity, and can be used on the guide frame climbing working platform. In the climbing stage, it plays the role of anti-falling, guarantees the safety of mechanical equipment operation, and solves the problem of insufficient braking force that may occur in the long-term electromagnetic braking of the motor and the high degree of manual intervention of the existing locking device during the construction stage of the main structure of the prefabricated building. The problem of poor precision
