Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic pump station equipment, specifically a heat dissipation structure for a jack hydraulic pump station. Background Technology

[0002] A hydraulic pump station is a hydraulic power source device consisting of a hydraulic pump, a drive motor, an oil tank, and other parts. The hydraulic pump station uses hydraulic oil as the fuel, which is delivered by the drive motor through the hydraulic pump to regulate the direction, pressure, and flow rate, and is ultimately used by the entire system. The hydraulic oil is recycled, and after a period of use, the oil temperature may become too high, so heat dissipation is required.

[0003] Existing hydraulic pump stations rely on the hydraulic oil itself for heat dissipation during circulation, which is slow. Over time, this leads to a buildup of heat, and excessively rapid or forceful operation can cause the pump station to overheat, resulting in shutdowns and hydraulic oil leaks. Therefore, we propose a heat dissipation structure for jack-type hydraulic pump stations to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a heat dissipation structure for a hydraulic pump station for jacks, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation structure for a hydraulic pump station, including a support base.

[0006] A plurality of first brackets are fixedly connected to the upper right end of the support base. A first hydraulic cylinder is fixedly connected to the top of the first bracket. A second bracket is fixedly connected to the top of the first hydraulic cylinder. A first top plate is fixedly connected to the top of the second bracket. An electric telescopic rod is fixedly connected to the top of the first top plate. The electric telescopic rod extends downward and passes through the top of the first top plate and the first hydraulic cylinder. A first piston is fixedly connected to the lower end of the electric telescopic rod. The first piston is slidably connected to the inner wall of the first hydraulic cylinder.

[0007] Furthermore, a third bracket is fixedly connected to the upper left end of the support base, and a second top plate is fixedly connected to the top of the third bracket.

[0008] Furthermore, a second hydraulic cylinder is fixedly connected to the top of the second top plate, and a piston rod is slidably connected to the middle of the second hydraulic cylinder.

A first one-way valve is fixedly connected to the middle of the oil outlet pipe, and one end of the oil outlet pipe is connected to the bottom of the first oil cylinder.

[0010] Furthermore, the bottom of the first oil cylinder is connected to an oil inlet pipe, and a second one-way valve is fixedly connected to the middle of the oil inlet pipe. One end of the oil inlet pipe is connected to the bottom of the second oil cylinder.

[0011] Furthermore, a return pipe is connected to the bottom front end of the second cylinder, a control valve is fixedly connected to the middle of the return pipe, and the lower end of the return pipe is connected to the oil tank.

[0012] Furthermore, a cooling box is fixedly connected to the top center of the support base, and ventilation openings are provided on both the left and right sides of the cooling box. A blower is fixedly connected to the front end of the cooling box.

[0013] Furthermore, a water pump is connected to the bottom rear end of the cooling box, and a water pump is fixedly connected to the top end of the water pump. A water outlet pipe is fixedly connected to the output end of the water pump. One end of the water outlet pipe passes through the top of the cooling box, and a nozzle is threadedly connected to the other end of the water outlet pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By incorporating a blower, water pump, and nozzles, and employing a dual cooling mode of air cooling (forced convection by the blower) + water cooling (atomized spray), the limitations of traditional single cooling methods are overcome. This avoids the risk of system pressure leakage caused by the decrease in oil viscosity at high temperatures, effectively improving cooling efficiency. The nozzles and water outlet pipes are connected by threads, facilitating the cleaning of scale or replacement. The cooling box, water outlet pipe, water pump, and water extraction pipe facilitate the recycling of spray water, saving water resources. The first and second check valves prevent oil backflow and reduce the hydraulic shock failure rate. Attached Figure Description

An oil tank 12 is provided at the upper left end of the support base 1. An oil outlet pipe 24 is connected to the lower right end of the oil tank 12. A first check valve 13 is fixedly connected to the middle of the oil outlet pipe 24.

A second check valve 15 is fixedly connected to the middle of the oil inlet pipe 14. One end of the oil inlet pipe 14 is connected to... The bottom of the second oil cylinder 10 is connected to a return pipe 16, and a control valve 17 is fixedly connected to the middle of the return pipe 16. The lower end of the return pipe 16 is connected to the oil tank 12. A cooling box 18 is fixedly connected to the middle top of the support base 1.

[0027] When this utility model is in use, the retraction process of the electric telescopic rod during the oil intake stage is as follows:

[0028] The retraction of the electric telescopic rod 6 causes the first piston 7 to move upward, increasing the volume of the inner cavity of the first oil cylinder 3 and creating negative pressure.

[0029] Hydraulic oil in tank 12 enters the bottom of cylinder 3 through outlet pipe 24, opening first check valve 13. First check valve 13 opens and flows from tank to cylinder 3. Second check valve 15 closes to prevent backflow of oil in cylinder 3.

[0030] The extension procedure of the electric telescopic rod during the oil pressurization output stage:

[0031] The electric telescopic rod 6 extends → pushes the first piston 7 down → pressurizes the oil in the first cylinder 3.

[0032] High-pressure oil enters the second cylinder 10 through the inlet pipe 14, opening the second check valve 15 and pushing the piston rod 11 to lift the load. The valves function as follows: the first check valve 13 closes to prevent oil from returning to the tank; the second check valve 15 opens, and the flow direction is: first cylinder → second cylinder. Oil return control is optional. Opening the manual control valve 17 results in partially heated oil in the second cylinder 10 returning to the tank 12 via the return pipe 16 for recooling. The purpose is to accelerate heat exchange and prevent high-temperature oil from remaining in the actuator.

[0033] Working principle of heat dissipation system

[0034] Blower 19 starts → Forced airflow passes through the double-sided ventilation openings of cooling box 18 → directly blows onto the surface of oil tank 12 and oil pipes;

[0035] Water pump 21 starts → drawing cooling water from the bottom of cooling tank 18 → pressurizing and transporting it through water pumping pipe 20 → passing through water outlet pipe 22 → spraying out from threaded atomizing nozzle 23, the water mist evenly covers the surface of oil tank 12, oil pipe and hydraulic components → liquid water absorbs heat and evaporates → quickly removes heat from high-temperature components due to phase change heat absorption effect.
