Embodiment Construction
[0011] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.
[0012] The present invention is a new type of roadheader specially designed to meet the increasing installed power under the premise that the overall size of the machine is basically unchanged due to the limitation of the roadway space, and is beneficial to solve the problem of insufficient space when the whole machine is installed and matched with other accessories. It is a compact device with high power and small volume integrated with hydraulic pump station and oil tank.
[0013] The device is mainly composed of motor 1, oil tank 2, elastic coupling 3, circular sleeve 8, double variable plunger pump 4, two shock absorber throats 5, flange butterfly valve 6, liquid level and temperature gauge 7, etc. (Such as figure 1 shown). The motor and the hydraulic pump are respectively installed on both sides of the fuel tank and the top of the fuel ta...

The invention belongs to the technical field of boom-type roadheader equipment in coal mine underground, in particular to an integrated compact high power hydraulic power unit for a novel heading machine, solving the problem that the conventional heading machine is globally restricted by tunnel space, and cannot fulfill the installed power which is gradually increased. The hydraulic power unit comprises a motor, an oil tank and a hydraulic pump, wherein the motor and the hydraulic pump are arranged on two sides of the oil tank respectively, and the top of the oil tank is used as an installation base; an independent space with two opening ends is arranged in the oil tank in the horizontal direction; and the motor and the hydraulic pump are connected through an elastic coupling which is built in the independent space in the oil tank. The integrated compact type high-power hydraulic power unit has the beneficial effects of small volume, high power, excellent oil absorption effect and high work reliability, can effectively reduce the space of the power unit and the oil tank in the whole machine, and solves the problem that the gradually increased installed power is fulfilled on the premise of basically unchanged appearance size of the machine, and the space is not sufficient when other accessories are installed in complete machine assembly.
Description
technical field [0001] The invention belongs to the technical field of cantilever-type roadheader equipment in coal mines, and in particular relates to an integrated compact high-power hydraulic pump station for cantilever-type roadheaders in fully mechanized mining working faces in coal mines. Background technique [0002] Traditional cantilever-type roadheaders, hydraulic pump stations and hydraulic oil tanks are generally arranged in splits. Along the side of the machine, they are strung together like candied haws, occupying a large space on the machine. With the increasing requirements for equipment development in the application field of roadheaders, the installed power is getting larger and larger, and the volume of the fuel tank and pumping station is also increasing accordingly. The characteristics and layout will bring great difficulties to the overall layout of the machine. When the installed power reaches a certain range, it will even become a factor that hinders ...
