Description

Technical Field

[0001] This utility model relates to the field of hydraulic pump station technology, and more specifically, to a portable hydraulic pump station. Background Technology

[0002] A hydraulic pump station is a device used to hydraulically drive hydraulically controlled components, such as hydraulic wrenches, hydraulic cylinders, and screw tensioners. Currently, commercially available hydraulic pump stations mainly consist of an oil tank, a support plate, a motor, a hydraulic pump body assembly, and a hydraulic valve block assembly. The support plate is sealed and fixed to the opening at the top of the oil tank. The motor and hydraulic valve block assembly are both fixed to the upper end of the support plate. The hydraulic pump body assembly is located inside the oil tank and fixed to the lower end of the support plate. The hydraulic pump body assembly is connected to the output shaft of the motor, and the hydraulic valve block assembly is connected to the hydraulic pump body assembly via a connecting pipe. In this structure, because the hydraulic pump station is equipped with a motor to drive the hydraulic pump body assembly, it suffers from a large size and weight, hindering miniaturization and making it inconvenient to carry when outdoor use is required. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a portable hydraulic pump station that can be driven by an electric drill, so that the hydraulic pump station does not need to be equipped with a motor for driving the hydraulic pump body components, thus achieving the purpose of small size and light weight, so as to facilitate the carrying of the hydraulic pump station.

[0004] This utility model provides a portable hydraulic pump station, including an oil tank, a support plate, a hydraulic pump body assembly, and a hydraulic valve block assembly. The support plate is sealed and fixed to the opening at the upper end of the oil tank. The hydraulic valve block assembly is fixed to the upper end of the support plate. The hydraulic pump body assembly is located inside the oil tank and fixed to the lower end of the support plate. The oil inlet end of the hydraulic valve block assembly is connected to the oil outlet end of the hydraulic pump body assembly through an oil inlet pipe. The portable hydraulic pump station also includes a reduction gear assembly. The reduction gear assembly is fixed to the upper end of the support plate. The rotating shaft of the hydraulic pump body assembly is drivenly connected to the output shaft of the reduction gear assembly. The input shaft of the reduction gear assembly is used for drively connecting to the output end of an electric drill.

[0005] By adopting the above-described structure, this utility model enables the hydraulic pump station to be driven by a hand drill, thereby eliminating the need for a separate motor to drive the hydraulic pump body components. This results in a small size and light weight, making the hydraulic pump station easy to carry. Furthermore, existing hand drills on the market all come with built-in lithium batteries, so the hydraulic pump station does not require an external power source when driven by the hand drill, offering the advantage of convenient use.

[0006] In one possible implementation, the reduction gear assembly includes a support sleeve and a reduction gear set connected inside the support sleeve; the lower end of the support sleeve is fixed to the upper end of the support plate, the upper end of the output shaft is driven to the output end of the reduction gear set, and the lower end of the input shaft is driven to the input end of the reduction gear set; by using this reduction gear assembly, when the input shaft is connected to the output end of the electric drill, and the electric drill drives the input shaft to rotate, the input shaft can drive the reduction gear set to rotate, and the reduction gear set can drive the output shaft to rotate. At this time, the output shaft can drive the rotating shaft in the hydraulic pump body assembly to rotate, that is, the hydraulic pump body assembly can pump oil, that is, the hydraulic pump body assembly can pump the hydraulic oil located in the oil tank to the hydraulic valve block assembly through the oil inlet pipe, so that the hydraulic valve block assembly supplies oil to the hydraulically controlled components.

[0007] In one possible implementation, the lower end of the output shaft is inserted into the upper end of the rotating shaft, and the output shaft is circumferentially limited and connected to the rotating shaft by a limiting key; with this structure, the lower end of the output shaft can be reliably connected to the rotating shaft, that is, when the output shaft rotates, it can reliably drive the rotating shaft to rotate synchronously, so as to drive the hydraulic pump body assembly.

[0008] In one possible implementation, the upper end of the input shaft is inserted into and circumferentially limited by the output end of the electric drill; with this structure, the upper end of the input shaft can be reliably connected to the output end of the electric drill, that is, the electric drill can reliably drive the output shaft to rotate, so as to drive the reduction gear assembly.

[0009] In one possible implementation, an annular protrusion is provided on the outer peripheral wall of the lower end of the support sleeve. The annular protrusion supports the support plate, and the support sleeve and the support plate are fastened by a number of bolts that are spaced apart around the circumferential direction of the support sleeve. The threaded part of each bolt is movably inserted in the annular protrusion and threadedly fastened to the support plate. With this structure, the lower end of the support sleeve can be reliably fixed to the support plate by a number of bolts, that is, the reduction gear assembly can be reliably fixed to the upper end of the support plate.

[0010] In one possible implementation, an annular boss is provided on the lower end face of the support sleeve, and an annular groove is provided on the upper end of the support plate. The annular boss is fitted into the annular groove from top to bottom, and the outer peripheral wall of the annular boss fits against the inner peripheral wall of the annular groove. With this structure, when the reduction gear assembly and the support plate are fixed, the positioning and limiting function of the support sleeve and the support plate can be achieved by the interlocking action of the annular boss and the annular groove. This facilitates the fixing of the reduction gear assembly and the support plate, improves the reliability of the reduction gear assembly and the support plate after fixing, and ensures the coaxiality of the output shaft in the reduction gear assembly and the rotating shaft in the hydraulic pump body assembly, so that the reduction gear assembly can reliably drive the hydraulic pump body assembly.

[0011] In one possible implementation, a number of shock-absorbing pads are fixed at the edge of the bottom of the oil tank in a circumferentially spaced manner. By fixing a number of shock-absorbing pads at a circumferentially spaced manner on the bottom of the oil tank, the vibration of the hydraulic pump station can be effectively reduced and the noise of the hydraulic pump station can be effectively eliminated when the electric drill drives the hydraulic pump body assembly through the reduction gear assembly.

[0012] In one possible implementation, an oil level indicator is connected to the side wall of the oil tank; by setting the oil level indicator, the user can conveniently observe the remaining amount of hydraulic oil in the oil tank, so that the user can replenish the hydraulic oil in the oil tank in a timely manner.

[0013] In one possible implementation, a drain plug is connected to the side wall of the oil tank and near the bottom of the oil tank. By setting the drain plug, when it is necessary to replace the hydraulic oil in the oil tank, the drain plug can be removed, and the hydraulic oil in the oil tank can be drained to facilitate the replacement of the hydraulic oil in the oil tank.
