Problems solved by technology

[0002] At present, the driving device on the cableway, especially the cableway in the coal mine, is that the motor drives the driving wheel through the gearbox. The disadvantages are: first, the volume is large, the parts are easy to wear, and the maintenance is large; second, it cannot be steplessly adjusted; third, it cannot be empty. Starting, the impact on the power grid and mechanical components is greater

Embodiment Construction

[0015] Such as figure 1 As shown, a mining cableway hydraulic drive system includes a motor 1, a closed pump 2, and a hydraulic drive system. The motor 1 is connected to the closed pump 2, and a filter 5 is arranged on the oil outlet pipe of the fuel tank 4. In the fuel tank 4 The oil return pipe is connected to the radiator 19, and the connection relationship of the hydraulic drive system is: the oil inlet S of the closed pump 2 is connected to the oil outlet pipe of the oil tank 4, and the closed pump 2 has a built-in charge pump oil outlet X3 and a damping valve block 7, the other end of the damping valve block 7 is respectively connected with the P port driving the explosion-proof three-position four-way electromagnetic reversing valve 8 and the explosion-proof proportional overflow valve 9, and the other end of the explosion-proof proportional overflow valve 9 is respectively connected with Drive the T port of the explosion-proof three-position four-way electromagnetic re...

Abstract

The invention discloses a hydraulic driving system for a ropeway for mines, which comprises a motor, a closed type pump, a gear pump, the hydraulic driving system, a hydraulic tension system and a hydraulic brake system. The hydraulic driving system for the ropeway for the mines has the following advantages: (1) the hydraulic driving system can realize stepless speed adjustment and positive and reverse rotation of the ropeway, and the ropeway can rotate positively or reversely at a low speed (which can be set freely) to check a steel wire rope; (2) no-load starting of the motor can be realized so as to prolong service life of the motor and electrical elements; (3) acceleration and deceleration properties of starting and stopping can be freely set (the time for starting acceleration and stopping deceleration can be set) so as to improve riding comfort; (4) the hydraulic tension system has the characteristics of compact volume, large tensile force and stepless adjustment, and simultaneously can display the tensile force on line to ensure realization of tension of constant tensile force under the condition of load changing; (5) the system is suitable for severe working environmental (dusty, damp and explosion-proof) conditions, hydraulic oil flow flows between the hydraulic pump and the motor circularly, and a main oil path is not contacted with air directly, so air suction cannot occur and the system is not easy to be polluted; and (6) because a flame-proof device (such as a flame-proof transducer) is not needed to adjust speed, the hydraulic system for adjusting speed is more safe in the underground gas environment due to no explosion danger factor.

Description

technical field [0001] The invention relates to a cableway hydraulic drive system. Background technique [0002] At present, the driving device on the cableway, especially the underground cableway in the coal mine, is that the motor drives the driving wheel through the gearbox. The disadvantages are that the volume is large, the parts are easy to wear, and the maintenance is large; the second is that it cannot be adjusted steplessly; the third is that it cannot be empty. Starting, the impact on the power grid and mechanical components is relatively large. Contents of the invention [0003] The object of the present invention is to provide a cableway hydraulic drive system with small volume, no-load start and stepless speed regulation. [0004] The purpose of the present invention is achieved in the following manner: a mining cableway hydraulic drive system, comprising a motor, a closed pump, a hydraulic drive system, the closed pump is connected to the motor, a filter is ...
