Assembly and disassembly device and method for support roller of drum mixer

Abstract

The invention belongs to the field of an assembly and disassembly technology for a drum mixer, and in particular relates to an assembly and disassembly device and method for a support roller of a drum mixer. The device is characterized by comprising a base foundation, a base, a group of hydraulic jacks, a bracket, guide rods and a guide sleeve, wherein the base is connected with the base foundation; the group of hydraulic jacks are arranged on the base; the bracket is connected with the tops of the group of hydraulic jacks in a propping manner; the guide rods are arranged at the two sides of the bracket respectively; the guide sleeve is in slip connection with the guide rods; and one end of the guide sleeve is connected with the bracket. The upper surface of the bracket is of a concave arc shape and matched with the outer surface of the drum body of the drum mixer. The assembly / disassembly method comprises the following steps: starting the hydraulic jacks are started; utilizing the bracket to support the drum body to move upwards under the effect of the hydraulic jacks; after the drum body moves to a pre-set position, stopping the rise of the hydraulic jacks; disassembling or assembling the support roller so that the hydraulic jacks fall back; and utilizing the bracket to support the drum body to fall back to the original position under the effect of gravity. The device provided by the invention has a simple structure, is convenient to operate, safe, reliable, economical and practical, and ensures that the time and labor are saved once for all.

Description

technical field [0001] The invention belongs to the technical field of disassembling and assembling rollers of a cylinder mixer, and in particular relates to a disassembling device and a method for disassembling and disassembling a roller of a cylinder mixer. Background technique [0002] In the mixer, the roller device is an important part, its purpose is to support and maintain the normal operation of the mixer. When the idler roller needs to be overhauled or replaced, it is difficult to disassemble the idler roller. It is necessary to directly lift the cylinder with a jack. Due to the large diameter and length of the cylinder, the stability and safety of the jacking are poor. Simultaneously, this method is also limited to the idler roller on one side of the mixer at the same time. Contents of the invention [0003] The purpose of the present invention is to provide a simple structure, economical, practical, safe and reliable cylinder mixer roller disassembly device. ...

AI Technical Summary

Problems solved by technology

When the idler roller needs to be repaired or replaced, it is difficult to disassemble and assemble the idler roller. It is necessary to directly lift the cylinder with a jack. Due to the large diameter and long cylinder, the stability and safety of the jacking are poor.

At the same time, this method is also limited to the simultaneous disassembly and assembly of the rollers on one side of the mixer.
