Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pumps, and more specifically, to a stern anti-leakage hydraulic pump. Background Art

[0002] The stern hydraulic pump is an independent hydraulic device that supplies oil according to the requirements of the drive device and controls the direction, pressure and flow of the oil. It is suitable for various hydraulic machinery where the main engine and hydraulic device are separable. The hydraulic pump station uses hydraulic oil that meets the requirements of the hydraulic system as the medium. The motor pumps out hydraulic oil with a flow rate that meets the requirements for use in the system. The hydraulic oil is generally circulated. During use, if the oil pipe is damaged, it will cause a large amount of hydraulic oil leakage.

[0003] For example, CN219472475U discloses a leakage-proof hydraulic pump station, the key points of its technical solution are: it includes a hydraulic oil tank base, a hydraulic pump is fixed on the upper left side of the hydraulic oil tank base, an oil outlet pipe is threadedly connected to the outlet of the hydraulic pump, and an overflow valve and a pressure detector assembly are respectively installed on the outside of the oil outlet pipe; the upper right side of the hydraulic oil tank base is threadedly connected to an oil return line, and the inner side of the return line is threadedly connected to a one-way valve; it is mainly through the arrangement of a sealing connection shell, an electromagnetic valve, a push rod piston, a valve switch and a compression spring, which is conducive to detecting the pressure in the pipeline and sealing the oil circuit when the pressure drops instantly.

[0004] The above-mentioned stern anti-leakage hydraulic pump still has certain shortcomings: since the stern anti-leakage hydraulic pump does not have the function of wiring, once the motor connecting wires are entangled with other components, it will affect the subsequent maintenance work of the motor, thereby reducing the practicality of the device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a stern anti-leakage hydraulic pump. By setting a wiring harness assembly, before the hydraulic pump main body works, the second limit frame inside the wiring harness assembly is first pulled outward. After pulling a certain distance, one end of the connecting wire is passed through the interior of the two sets of wiring harness assemblies, and then the second limit frame is slowly loosened. At this time, the reset spring will restore the second limit frame to its original position, so that the first wiring harness wheel and the second wiring harness wheel will limit the position of the passing connecting wire, thereby avoiding the phenomenon of the connecting wire being entangled with other components, so as to facilitate later maintenance work and solve the problems existing in the prior art.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a stern anti-leakage hydraulic pump, comprising a hydraulic pump body, a motor is fixedly connected to one side of the upper surface of the hydraulic pump body, two wiring harness assemblies are fixedly connected to one side of the upper surface of the hydraulic pump body, the top of the motor is electrically connected to a connecting wire, and a moisture-proof assembly is embedded in the side wall of the hydraulic pump body.

[0007] The wiring harness assembly includes a base and a first limiting frame. The upper surface of the base is fixedly connected to the first limiting frame, and the lower surface of the base is connected to one side of the upper surface of the hydraulic pump body.

[0008] Two first bearings are symmetrically mounted on the surface of the first limiting frame along the center, a first cable pulley is fixedly sleeved inside the first bearing, and the top end of the first cable pulley is adapted to the surface of the connecting line.

[0009] The top of the first limiting frame is provided with a plurality of limiting holes in a rectangular array, the bottom ends of the limiting holes are fixedly connected to a telescopic rod, and a reset spring is fixedly sleeved on the surface of the telescopic rod.

[0010] Among them, the top end of the return spring is fixedly connected to a second limit frame, and two second bearings are symmetrically inlaid and installed on the surface of the second limit frame along the center. The interior of the second bearing is fixedly sleeved with a second wiring wheel, and the bottom end of the second wiring wheel is adapted to the surface of the connecting line.

[0011] Wherein, the moisture-proof component includes a dehumidifier and a connecting elbow, and the side wall of the dehumidifier is connected to the connecting elbow.

[0012] One end of the connecting elbow is connected to a processing box, a side wall of the processing box is connected to an air outlet pipe, and a heater is provided inside the processing box.

[0013] The beneficial effects of the above technical solution of the utility model are as follows:

[0014] 1. In the above solution, the stern anti-leakage hydraulic pump is provided with a moisture-proof component. When humid air enters the interior of the hydraulic pump body, the dehumidifier inside the moisture-proof component is started and put into operation. The dehumidifier then absorbs the humid air into the interior, and then the gas is transported to the interior of the treatment box for treatment through the connecting elbow. Because the interior of the treatment box is provided with a heater, the transported humid air can be heated, and finally the gas is discharged through the outlet pipe, thereby ensuring the quality of the internal parts of the hydraulic pump body and improving the working efficiency of the device;

[0015] 2. In the above scheme, the stern anti-leakage hydraulic pump is provided with a harness assembly. Before the main body of the hydraulic pump works, the second limit frame inside the harness assembly is first pulled outward. After pulling a certain distance, one end of the connecting wire is passed through the inside of the two sets of harness assemblies, and then the second limit frame is slowly loosened. At this time, the reset spring will restore the second limit frame to its original position, so that the first harness wheel and the second harness wheel will limit the position of the passing connecting wire, thereby avoiding the phenomenon of the connecting wire being entangled with other components, so as to facilitate later maintenance work.

DETAILED DESCRIPTION

[0022] In order to make the technical problems to be solved, technical solutions and advantages of the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0025] The harness assembly 3 includes a base 31 and a first limiting frame 32. The upper surface of the base 31 is fixedly connected to the first limiting frame 32. The lower surface of the base 31 is connected to one side of the upper surface of the hydraulic pump body 1. The surface of the first limiting frame 32 is symmetrically inlaid with two first bearings 33 along the center. The first bearing 33 is fixedly sleeved with a first harness wheel 34 inside. The top of the first harness wheel 34 is adapted to the surface of the connecting line 4. The top of the first limiting frame 32 is provided with a plurality of limiting holes in a rectangular array. The bottom end of the limiting hole is fixedly connected to a telescopic rod 35. The surface of the telescopic rod 35 is fixed. A return spring 36 is sleeved, and the top of the return spring 36 is fixedly connected to a second limit frame 37. Two second bearings 38 are symmetrically inlaid on the surface of the second limit frame 37 along the center. A second cable pulley 39 is fixedly sleeved inside the second bearing 38. The bottom end of the second cable pulley 39 is adapted to the surface of the connecting line 4. The moisture-proof component 5 includes a dehumidifier 51 and a connecting elbow 52. The side wall of the dehumidifier 51 is connected to the connecting elbow 52. One end of the connecting elbow 52 is connected to a processing box 53. The side wall of the processing box 53 is connected to an air outlet pipe 54. A heater is provided inside the processing box 53.

[0026] Benefits: By disposing the first bearing 33 and the second bearing 38 , sliding friction is used instead of static friction to reduce the friction force on the connecting wire 4 when the connecting wire 4 is pulled.

[0027] The working process of this utility model is as follows:

[0028] When the stern anti-leakage hydraulic pump is in use, in order to improve the working efficiency of the device, a moisture-proof component 5 is provided. When humid air enters the interior of the hydraulic pump body 1, the dehumidifier 51 inside the moisture-proof component 5 is started to work. Then the dehumidifier 51 will absorb the humid air into the interior, and then the gas will be transported to the interior of the processing box 53 for processing through the connecting elbow 52. Because a heater is provided inside the processing box 53, the transported humid air can be heated, and finally the gas is discharged through the outlet pipe 54, thereby ensuring the quality of the internal parts of the hydraulic pump body 1 and improving the working efficiency of the device.

[0029] In the above scheme, when the stern anti-leakage hydraulic pump is in use, a wiring harness assembly 3 is provided to facilitate subsequent maintenance work. Before the hydraulic pump main body 1 works, the second limit frame 37 inside the wiring harness assembly 3 is first pulled outward. After pulling a certain distance, one end of the connecting line 4 is passed through the inside of the two sets of wiring harness assemblies 3, and then the second limit frame 37 is slowly loosened. At this time, the reset spring 36 will restore the second limit frame 37 to its original position, so that the first wiring harness wheel 34 and the second wiring harness wheel 39 will limit the position of the passing connecting line 4, thereby avoiding the phenomenon of the connecting line 4 being entangled with other components, so as to facilitate subsequent maintenance work.
