Emergency reset system for combined type railway large-scale road maintenance machine

Abstract

The invention discloses an emergency reset system for a combined type railway large-scale road maintenance machine. The emergency reset system for the combined type railway large-scale road maintenance machine comprises a lampshade and a low-pressure pump, an internal shaft type oil pump special motor is installed in the lampshade, a high-pressure pump is installed under a connecting shaft, a first hydraulic pipeline is installed under a high-pressure pump oil outlet, a low-pressure pump oil outlet is formed in the surface of the low-pressure pump, a second hydraulic pipeline is installed below the low-pressure pump oil outlet, a low-pressure oil output pipe is installed below a low-pressure valve assembly integrated unit, and a first stop valve is arranged in the low-pressure valve assembly integrated unit. According to the emergency reset system for the combined type railway large-scale road maintenance machine, two sets of independent emergency systems commonly adopted in an original large machine are designed and combined into one system, the installation space is reduced, the emergency reset efficiency is improved, the emergency reset requirements of operating devices of various large-scale road maintenance machines are met, and the emergency start and reset requirements of the entire machine are met.

Description

technical field [0001] The invention relates to the technical field of railway maintenance equipment, in particular to a combined emergency reset system for large-scale railway maintenance machinery. Background technique [0002] As an efficient railway maintenance equipment, large-scale railway maintenance machinery is widely used in railway maintenance operations. However, due to its complex structure and harsh operating conditions, it is inevitable that there will be failures during construction or operation. Sudden failures of the engine, electrical system, or hydraulic system make the operating device unable to return to the operating position, resulting in the inability of the large machine to operate commercially. If these faults are not dealt with in time, it may affect the operation of subsequent vehicles, and even lead to accidents. If the machine cannot be reset in time after falling off the road, it will also cause serious consequences. At present, auxiliary powe...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a combined emergency reset system for large-scale railway maintenance machinery to solve the problem mentioned in the above background technology that auxiliary power equipment for emergency reset of operating devices is generally installed on general large machines, but the equipment can only meet the needs of its own operations. The needs of the device (the required pressure is low), when the vehicle falls off the road, the auxiliary power equipment cannot provide enough power (requires high pressure) for the vehicle to recover, and another system needs to be equipped to meet the requirements. requirements, this method is complex and inefficient
