Problems solved by technology

[0002] At present, the oil circuit in the electro-hydraulic switch machine is mostly connected by oil pipes and joints. Since this connection method has very high requirements on the machining accuracy and assembly process of the parts, it is difficult to ensure the pass rate of the whole machine assembly in mass production.
In addition, there is an unavoidable problem of hydraulic oil leakage. If it accumulates over time, the stroke of the main oil cylinder will be shortened, which will cause the action lever to pull the switch in place.
There are potential safety hazards that affect driving safety

Abstract

The invention relates to the technical field of point switches, in particular to a hydraulic oil road plate type connection structure for a point switch. The hydraulic oil road plate-type connection structure comprises an oil pump oil plate, a motor oil plate, an oil plate connection block, a main oil cylinder connector cushion block, a main oil cylinder connection valve and a clamp plate; the oilpump oil plate and the motor oil plate are installed on a bottom housing and a locking oil cylinder, the oil plate connection block is fixed between the oil pump oil plate and the motor oil plate, the main oil cylinder connector cushion block is installed at an oil plate notch, and the main oil cylinder connection valve is fixed between the oil pump oil plate, the motor oil plate and a main oil cylinder through the clamp plate. An oil road is processed inside an oil road plate, plate pieces are directly connected to an oil pump, the main oil cylinder and the locking oil cylinder to form a closed hydraulic circulation loop, all parts with oil pipelines are directly connected within a plane, and thus oil leakage is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of switch machines, in particular to a hydraulic oil circuit plate connection structure for a switch machine. Background technique [0002] At present, the oil circuit in the electro-hydraulic switch machine is mostly connected by oil pipes and joints. Since this connection method has very high requirements on the machining accuracy and assembly process of the parts, it is difficult to guarantee the pass rate of the whole machine assembly in mass production. In addition, there is an unavoidable problem of hydraulic oil leakage, and if it accumulates over time, the stroke of the main oil cylinder will be shortened, which will cause the actuation rod to not pull the switch in place. There are potential safety hazards that affect driving safety. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned technologies, and provide a hydraulic ...
