Description

Technical Field

[0001] This utility model relates to the field of hydraulic filling pump technology, and in particular to an integrated hydraulic filling pump for use in overburden separation. Background Technology

[0002] After underground coal seam mining, the original rock stress in the overlying strata above the goaf and coal pillars is disrupted, leading to overlying strata movement, deformation, fracture, and even collapse, causing surface subsidence and serious hazards. During the movement of the rock strata, an abscission zone, composed of multiple delaminations, exists above the water-conducting fracture zone. This zone can be used for grouting. By drilling into the overlying strata from the surface and injecting grout into the abscission space, further damage to the rock mass above the abscission space can be inhibited. Traditional hydraulic grouting pump systems use a split structure between the pump station and the pump body. The pump station includes equipment such as oil pumps, motors, oil tanks, and coolers, while the pump body contains oil cylinders, grout cylinders, connecting boxes, and various valve groups. The large number of components and the large space occupied result in low system integration, complex installation and maintenance, high transportation costs, and poor on-site layout flexibility. Furthermore, traditional F-series mechanical pumps are large in size, operate at high reciprocating frequencies, and have poor reliability. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses an integrated hydraulic filling pump. The drive pump station and the working pump body are arranged in parallel and placed on the same base. The working pump body adopts a parallel arrangement of two oil cylinders, and the cooler and control box are integrated at both ends of the chassis. This solves the problems of large space occupation and poor equipment reliability of traditional hydraulic grouting pumps.

[0004] The specific technical solution is as follows:

[0005] An integrated hydraulic filling pump includes a base, a drive pump station, and a working pump body. The drive pump station and the working pump body are arranged on the left and right sides of the base. The drive pump station includes a motor, an oil pump, an oil tank, and two coolers arranged sequentially along the length of the base. The oil pump is driven by the motor and pumps the hydraulic oil in the oil tank to the working pump body. The two coolers are arranged vertically at one end of the base and are used to cool the hydraulic oil flowing back from the working pump body before it is input into the oil tank.

[0006] The working pump body includes, in sequence along the length of the base, two hydraulic cylinders, a reversing valve assembly, a water tank, a slurry cylinder, and a slurry suction / discharge valve assembly. Two hydraulic cylinders are horizontally distributed at one end of the base, and one end of each hydraulic cylinder is horizontally connected to a slurry cylinder. A water tank is located at the connection point between the two hydraulic cylinders and the two slurry cylinders. One end of each slurry cylinder is connected to a slurry suction / discharge valve assembly. The reversing valve assembly is mounted above the two hydraulic cylinders via a support.

[0007] A control box is also provided at the other end of the base, and the control box is mounted above one end of the oil cylinder via a bracket.

[0008] Preferably, one end of the reversing valve assembly is connected to two oil cylinders respectively through an oil supply circuit pipe, one side of the reversing valve assembly is connected to the output end of the oil pump through an oil inlet pipe, and the other side of the reversing valve assembly is connected to two coolers respectively through a return oil pipe.

[0009] Preferably, one end of the return oil line extends below the oil cylinder and from the bottom of the water tank and the impeller cylinder to the two coolers.

[0010] Preferably, the two coolers are connected to the return oil filter element on one side of the oil tank via pipelines, and the oil tank is provided with an oil suction filter element at one end, which is connected to the oil pump inlet end via pipelines.

[0011] Preferably, the two coolers are fixed to one end of the base by a mounting bracket and are arranged vertically.

[0012] Preferably, one end of each of the two suction and discharge valve groups is connected to a suction pipe port, and the other end of the two suction and discharge valve groups is connected to a discharge pipe port. A pressure stabilizing tank is installed on the top of the discharge pipe port.

[0013] Preferably, the control box has an operation panel at the end furthest from the cooler.

[0014] The beneficial effects of this utility model are reflected in:

[0015] (1) The hydraulic filling pump adopts an integrated design of pump station and pump body, with the drive pump station and working pump body on the same chassis; the working pump body and the power pump station are arranged in a long parallel strip, which reduces the width of the overall equipment; the air-cooled position is located at the front of the oil tank, and adopts a double air-cooled superimposed structure, which effectively reduces the width and length of the equipment.

[0016] (2) The working pump body adopts a parallel arrangement of two oil cylinders. The two oil cylinders work alternately, which reduces the reciprocating frequency, improves the equipment reliability, and avoids the disadvantage of the traditional double-outlet reciprocating oil cylinder having a long stroke, resulting in an excessively long pump body.

[0017] (3) Compared with the traditional connecting box, the oil cylinder and the slurry cylinder are connected by a water tank. The water tank is the connecting part, and it can also cool and lubricate the piston in the slurry cylinder. The seal can be replaced in the water tank.

[0018] (4) A pressure stabilizing tank is installed at the upper end of the slurry discharge pipe, which can effectively absorb the pulsation of the slurry and increase the slurry discharge stability of the equipment. Attached Figure Description

The reversing valve group 7 is set above the two hydraulic cylinders 6 through a support 71 and connected to the two hydraulic cylinders 6, so that the two hydraulic cylinders 6 work alternately, avoiding the disadvantage of the traditional double-rod reciprocating hydraulic cylinder 6 having a long stroke, which leads to an excessively long pump body.

[0031] A control box 12 is also provided at the other end of the base. The control box 12 is mounted above one end of the oil cylinder 6 via a bracket 121. An operation panel 122 is provided on the control box 12 at the end away from the cooler 5 for easy operation.

[0032] In this embodiment, one end of the reversing valve assembly 7 is connected to the two oil cylinders 6 via an oil supply circuit pipe 72 to form a circuit. The oil supply circuit pipe 72 is located above the oil cylinders 6 and is arranged along their length. One side of the reversing valve assembly 7 is connected to the output end of the oil pump 3 via an oil inlet pipe 73. The other side of the reversing valve assembly 7 is connected to the inlet ends of the two coolers 5 via a return oil pipe 74. One end of the return oil pipe 74 extends downward to below the oil cylinders 6 and extends from the bottom of the water tank 8 and the impeller cylinder 9 to the two coolers 5.

[0033] In this embodiment, the cooler 5 used is an air-cooled radiator. The outlet ends of the two coolers 5 are connected to the return oil filter element 42 on one side of the oil tank 4 through pipelines. One end of the oil tank 4 is provided with an oil suction filter element 41, which is connected to the inlet end of the oil pump 3 through pipelines.
