Embodiment Construction

[0010] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, the hydraulic drive system of a monorail locomotive provided by the present invention is suitable for the use of a monorail locomotive. The hydraulic drive system includes a two-way variable pump 1, a first relief valve 2, a second relief valve 3, a third relief valve 4, a hydraulic motor 5, a charge pump 6, a first one-way valve 7, a second one-way Valve 8, two-position three-way manual reversing valve 9, brake cylinder 10, two-position two-way hydraulic control reversing valve 11 and oil tank 12.

[0012] Port A of the two-way variable variable pump 1 is connected to port C of the hydraulic motor 5, and port B of the two-way variable variable pump 1 is connected to port D of the hydraulic motor 5, that is, the high-pressure oil output by the two-way variable variable pump 1 directly enters the hydraulic motor 5 I...

Abstract

The present invention relates to the technical field of monorail cranes, particularly to a monorail crane locomotive hydraulic drive system, which comprises a bidirectional variable capacity pump, a first overflow valve, a second overflow valve, a third overflow valve, a hydraulic motor, an oil supplementing pump, a first check valve, a second check valve, a two-position three-way manual reversingvalve, a braking cylinder, a two-position two-way hydraulic control reversing valve and an oil groove. According to the present invention, the bidirectional variable capacity pump drives the hydraulic motor to rotate forward and backward so as to achieve the front-back movement of the monorail crane locomotive; by using the closed loop, the structure is compact, the reliability is strong, the driving efficiency is substantially improved, and the energy is saved; by using the braking cylinder, the hydraulic motor can be braked, such that the monorail crane locomotive can be stable at the stationary state; and by using the two-position two-way hydraulic control reversing valve, the heat generation of the braking cylinder during the braking can be avoided so as to prolong the service life ofthe braking cylinder.

Description

technical field [0001] The invention relates to the technical field of monorail cranes, in particular to a hydraulic drive system of a monorail crane locomotive. Background technique [0002] The monorail locomotive plays an increasingly important role in the auxiliary transportation system of the mine, and it is used more and more widely. The research and development of the monorail locomotive equipment, at the same time, it is not affected by the condition of the floor, the transportation roadway is conveniently arranged to save space, and the transportation efficiency is high. The relocation and reverse work of the fully mechanized mining face, which could only be completed in the past month, can be completed within a week by using the hydraulic control system of the monorail locomotive, which greatly improves the efficiency of auxiliary transportation and thus improves the efficiency of all staff. However, the existing hydraulic drive systems for monorail locomotives oft...
