Embodiment Construction

[0030] Specific embodiments of the present invention will be described below with reference to the drawings.

[0031] The hydraulic system of the rail welding car includes a hydraulic pump station for the rail welding car, which is used to provide a common pressure oil source for the outrigger hydraulic subsystem 16 and the crane hydraulic subsystem 17 of the rail welding car. For the sake of construction safety, the crane hydraulic subsystem 16 and the outrigger hydraulic subsystem 17 are not allowed to work at the same time, so setting up a public hydraulic pump station for them can not only improve safety and reduce costs, but also does not affect the actual use effect .

[0032] combine figure 1 , figure 2 with image 3 , the hydraulic pump station is a vertical structure, including a main body, the main body is provided with a fuel tank 1 and a main oil pump 2 connected to the fuel tank 1, and a main motor 3 is installed above the main body to provide power for the ma...

Abstract

The invention provides a hydraulic pump station for a rail welding vehicle. The hydraulic pump station comprises an oil tank, a main oil pump connected with the oil tank to pump oil outside, a main motor providing power for the main oil pump and an electromagnetic reversing valve communicated with the outside, wherein the electromagnetic reversing valve has an electromagnetic valve port A and an electromagnetic valve port B; the electromagnetic valve port A is communicated with an oil inlet of a crane hydraulic sub-system; the electromagnetic valve port B is communicated with an oil inlet of a support leg hydraulic sub-system; and the electromagnetic reversing valve starts one of the electromagnetic valve port A and the electromagnetic valve port B while closing the other one so as to realize that the electromagnetic valve port A and the electromagnetic valve port B are not started at the same time. The invention has the beneficial effects that: the crane hydraulic sub-system and the support leg hydraulic sub-system can share a hydraulic pump station to work, the structure of the hydraulic system of the rail welding vehicle is simplified, the cost is reduced, the potential safety hazard when the crane hydraulic sub-system and the support leg hydraulic sub-system work at the same time is eliminated, and the safety of the welding operation is greatly improved.

Description

technical field [0001] The invention relates to a hydraulic system of a rail welding car, in particular to a hydraulic pump station for a rail welding car. Background technique [0002] With the continuous development of my country's railway industry, railway construction began to advance on a large scale. The length of the rails completed in the factory is limited, while the construction and work of the outdoor rail welding station takes a long time and costs a lot. In order to improve the speed and efficiency of railway laying, rail welding cars are often used to complete the welding of each section of rails laid on the line. Due to mobile operations and other restrictions, non-self-propelled rail welding vehicles are often equipped with three sets of hydraulic systems, namely welding machine hydraulic system, crane hydraulic system and outrigger hydraulic system. All three sets of hydraulic systems need to be powered by hydraulic pump stations. In the prior art, three ...
