Shield tunneling machine rear matching wheel set hydraulic dismounting system and using method

Abstract

The invention discloses a shield tunneling machine rear matching wheel set hydraulic dismounting system and a using method. The system comprises a preparation platform, a rubber pipe assembly, a hydraulic cylinder, an operation platform and a pumping source device, and the operation platform comprises a bottom platform, a rotary arm pin shaft, stand columns, rotary arm lugs, a rotary arm sleeve, a rotary arms a chain block and a limiting baffle. The preparation platform is placed on one side of the bottom platform. The stand columns are welded to the upper surface of the bottom platform. The two rotary arm lugs are welded on the stand columns, and the rotary arm sleeve is arranged between the two rotary arm lugs. One end of the rotary arm is welded at the center of the cylindrical surface of the rotary arm sleeve, and the other end of the rotary arm is welded to the limiting baffle. The chain block is installed on the rotary arm, and the pump source device is arranged on the preparation platform or the operation platform close to the position of a workpiece and connected with the hydraulic cylinder through the rubber pipe assembly. The shield tunneling machine rear matching wheel set hydraulic dismounting system is firm in structure, the hydraulic cylinder is used for disassembling a wheel set pin shaft, damage to parts is reduced, the maintenance efficiency is improved, the cost is reduced, and safety is improved.

Description

technical field [0001] The invention relates to a guide wheel for a rear supporting wheel set of a shield tunneling machine and a dismantling system for a pin shaft thereof and a method for using the same, belonging to the field of maintenance of the rear supporting wheel set of a shield tunneling machine. Background technique [0002] The shield machine is a special tunneling machine, which is widely used in tunnel projects such as subways, railways, highways, municipalities, and hydropower. The wheel set, as the wheel set for the movement and guidance of the shield machine trailer, is an important component of it. The following problems exist in the disassembly and maintenance of the existing wheel set devices: 1) After the construction is completed, a considerable part of the wheel set pins are rusted or slightly deformed, and it is difficult to take the pins out of the wheels by traditional manual knocking; 2) the traditional The disassembly method often needs to spray ...

AI Technical Summary

Problems solved by technology

The following problems exist in the disassembly and maintenance of the existing wheel set devices: 1) After the construction is completed, a considerable part of the wheel set pins are rusted or slightly deformed, and it is difficult to take the pins out of the wheels by traditional manual knocking; 2) the traditional The disassembly method often needs to spray rust remover on the junction of the pin shaft and the wheel to pretreat the rusted part, and the workpiece is easily damaged during the knocking of the pin shaft, which has a long cycle, low efficiency, and poor economy; 3) due to the The device cannot be effectively fixed, and it is easy to cause the workpiece to fall or shift during the disassembly process, causing safety risks
