Abstract

The invention discloses an integrated hydraulic unit for an electro-hydraulic switch machine. The integrated hydraulic unit comprises a main oil cylinder (6) and an auxiliary oil cylinder (4) and further comprises a pump valve oil tank assembly (3), a motor (7), a left oil path connecting block (1), a right oil path connecting block (8) and an oil path connecting supporting plate (2). The auxiliary oil cylinder (4) and the main oil cylinder (6) are arranged side by side vertically and are fixed below the oil path connecting supporting plate (2). The auxiliary oil cylinder (4) is fixed to the main oil cylinder (6). The two sides of the oil path connecting supporting plate (2) are connected with the main oil cylinder (6) through the left oil path connecting block (1) and the right oil path connecting block (8). The pump valve oil tank assembly (3) is fixed above the oil path connecting supporting plate (2). The motor (7) is fixed above the oil path connecting supporting plate (2) and drives the oil pump (9) in the pump valve oil tank assembly (3) to work. The appearance size of the hydraulic unit is reduced, the whole hydraulic unit is integrated, the size of the whole machine is reduced, the disassembly and assembly are simple and convenient, and the reliability is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical and hydraulic transmission, in particular to an integrated hydraulic unit for an electro-hydraulic switch machine. Background technique [0002] The switch machine equipment is the executive mechanism of the switch control system. It is used for the switch lock and position state supervision of the switch. It is directly related to the driving safety, and the safety requirements of the switch machine equipment are extremely high. At present, the electro-hydraulic switch machine adopts the hydraulic transmission mode of the motor-driven oil pump to drive the oil cylinder to realize the switch conversion. The hydraulic transmission mode has the advantages of large output torque, stable transmission, self-lubrication, long life, etc., and can realize the expansion of auxiliary machines. [0003] The hydraulic unit of the existing electro-hydraulic switch machine, the hydraulic power part and the o...
