Saw blade dismounting and mounting device facilitating remote replacement operation

Abstract

The invention discloses a saw blade dismounting and mounting device facilitating remote replacement operation. The device comprises a saw cutting reduction gearbox and a saw cutting drive. The saw cutting drive is fixed to the saw cutting reduction gearbox, the saw cutting reduction gearbox comprises a saw cutting reduction gearbox output mechanism, and the saw cutting reduction gearbox output mechanism is fixed to the top end of the saw cutting reduction gearbox. The saw cutting reduction gearbox output mechanism is detachably connected with a saw blade assembly. According to the saw blade dismounting and mounting device facilitating remote replacement operation, a pressing nut on the saw cutting assembly is in nut connection with an output shaft in the middle of the saw cutting reduction gearbox output mechanism, the spiral tightening direction of threads of the pressing nut is opposite to the rotating direction of a saw blade in the saw cutting work process, and the contact face of the pressing face and the saw blade assembly is an annular section with the outer diameter being as large as possible. The enough large fastening torque for preventing the saw blade from loosening can be provided, the tedious steps of field operation are greatly simplified, meanwhile, the process of coarse positioning first and then fine positioning is completed step by step, and the installation requirement for high positioning precision can be met easily.

Description

technical field [0001] The invention belongs to the technical field of automation equipment, and in particular relates to a saw blade dismounting device for remote replacement operation. Background technique [0002] As we all know, circular saws are widely used in cutting materials such as stone, concrete, and metal. However, due to the sharp wear of the blade during cutting, the sharpness decreases rapidly, and the saw blade has to be replaced frequently to restore the cutting sharpness. Frequent replacement of the saw blade not only reduces the efficiency of production and processing, but also undoubtedly increases the cutting cost. In the case of large circular saws, the cost is higher, and often due to insufficient welding, the strength of the blade is not enough. [0003] When the reprocessing plant in the nuclear power plant is dealing with radioactive waste, in order to meet the principle of waste minimization, it is often necessary to cut and disassemble the equipm...

AI Technical Summary

Problems solved by technology

Solve the problem that the disassembly and assembly of existing saw blades involves high-precision installation and alignment, and the tightening of multiple fastening nuts, which often requires the cooperation of multiple people on site, which wastes manpower and material resources. If multiple people go to the site for installation, the nuclear pollution radiation on site will also Threats to human safety, etc.
