[0002] A hydraulic press is a machine that uses liquid as a working medium and is made according to Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: a machine body, a power system, and a hydraulic control system. The hydraulic control system is powered by an electric motor and uses a hydraulic pump to convert mechanical energy into pressure to push the hydraulic oil. By controlling various valves to change the flow direction of the hydraulic oil, the hydraulic cylinder is pushed to perform movements of different strokes and directions to meet the different movement needs of various equipment.

[0003] The existing hydraulic control device consists of a control cabinet and a hydraulic control system. Referring to a PLC-based hydraulic press control device with a reference to the announcement number CN211251467U, the patent can quickly take away the heat emitted by the control components during use by setting a through groove, a chassis, a bearing, a rotating shaft, a drive motor, a fan blade, a connecting pipe and a cover body to improve the heat dissipation efficiency. However, since the heat dissipation mechanism is located inside the control cabinet, when the heat dissipation mechanism is damaged, it is difficult to repair and replace it, which makes it inconvenient for people to use. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic control device with a simple structure and reasonable design in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A hydraulic control device includes a base plate, two support plates installed on the top of the base plate, and a control cabinet installed on the top of the two support plates. A heat sink with an opening on the top is installed on the top of the base plate through a moving mechanism. A heat dissipation mechanism and a refrigeration mechanism are installed inside the heat sink. A hydraulic control system is installed inside the control cabinet. The moving mechanism includes a strip groove opened on the top of the base plate, a threaded rod rotatably connected to the inside of the strip groove, a threaded sleeve threadedly connected to the outside of the threaded rod, and a rotating motor installed on one side of the base plate for driving the threaded rod to rotate. The top of the threaded sleeve is fixedly connected to the bottom of the heat sink.

[0007] As a further optimization scheme of the present invention, the heat dissipation mechanism includes a plurality of heat dissipation components rotatably connected to the inside of the heat dissipation box, the heat dissipation components include a rotating rod rotatably connected to the inner wall of the bottom of the heat dissipation box, and a plurality of rotating blades installed on the outside of the rotating rod, and a rotating mechanism for driving the rotating rod to rotate is installed inside the heat dissipation box.

[0009] As a further optimization scheme of the present invention, the refrigeration mechanism includes two mounting plates that can be detachably mounted inside the heat dissipation box, two connecting pipes mounted on the top of the two mounting plates, multiple refrigeration pipes mounted between the two connecting pipes, and a circulating pump and a refrigerator placed on the inner wall of the bottom of the heat dissipation box. Coolant is injected into the interior of the multiple refrigeration pipes, the inlet of the circulating pump is connected to one of the connecting pipes through a water inlet pipe, and the outlet of the circulating pump is connected to the inlet of the refrigerator through a water outlet pipe, and the outlet of the refrigerator is connected to the other connecting pipe through a connecting pipe.

[0010] As a further optimization solution of the present invention, a cover plate is installed on the top of the control cabinet by means of a plurality of bolts, and a plurality of heat dissipation holes are provided on the top of the cover plate and the bottom of the control cabinet.

[0011] As a further optimization solution of the present invention, two symmetrically arranged moving wheels are installed on one side of the bottom of the heat dissipation box, and two placement grooves for use with the moving wheels are opened on one side of the bottom plate.

[0012] The beneficial effect of the present invention is that when the heat dissipation mechanism needs to be repaired during use, the rotating motor can be started, and the rotating motor will drive the threaded rod to rotate. At this time, the threaded sleeve will move horizontally, thereby moving the heat dissipation box out from the bottom side of the control cabinet, thereby making it convenient for maintenance personnel to repair the heat dissipation mechanism inside the heat dissipation box and improving the maintenance efficiency.

[0020] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1 - Figure 6As shown, a hydraulic control device includes a base plate 1, two support plates 3 installed on the top of the base plate 1, and a control cabinet 4 installed on the top of the two support plates 3. A heat dissipation box 2 with an opening on the top is installed on the top of the base plate 1 through a moving mechanism. A heat dissipation mechanism is installed inside the heat dissipation box 2. The heat dissipation mechanism includes a plurality of heat dissipation components rotatably connected to the inside of the heat dissipation box 2. The heat dissipation component includes a rotating rod 17 rotatably connected to the inner wall of the bottom of the heat dissipation box 2, and a plurality of rotating blades 18 installed on the outside of the rotating rod 17. A rotating mechanism for driving the rotating rod 17 to rotate is installed inside the heat dissipation box 2. The rotating mechanism includes a driving motor 13 installed on the inner wall of the bottom of the heat dissipation box 2, a driving wheel 15 installed at the output end of the driving motor 13, and a driven wheel 16 installed on the outside of the rotating rod 17 and engaged with the driving wheel 15. A hydraulic control system 6 is installed inside the control cabinet 4. The moving mechanism includes an opening on the top of the base plate 1 The bar groove 8, the threaded rod 10 rotatably connected to the inside of the bar groove 8, the threaded sleeve 14 threadedly connected to the outside of the threaded rod 10, and the rotating motor 9 installed on one side of the base plate 1 for driving the threaded rod 10 to rotate, the top of the threaded sleeve 14 is fixedly connected to the bottom of the heat sink 2, the top of the control cabinet 4 is installed with a cover plate 5 by multiple bolts, the top of the cover plate 5 and the bottom of the control cabinet 4 are provided with multiple heat dissipation holes 7, and two symmetrical moving wheels 11 are installed on one side of the bottom of the heat sink 2. Two placement grooves 12 for use with the moving wheels 11 are provided on one side of the base plate 1. When the heat sink 2 is moved, one side of the heat sink 2 can be supported by the provided moving wheels 11, so that the heat sink 2 can be moved more smoothly. By opening the placement groove 12, when the heat sink 2 returns to its position, the base plate 1 is avoided from being obstructed, and the moving wheel 11 can be moved to the inside of the placement groove 12.

[0023] It should be noted that when this hydraulic control device is in use and the heat dissipation mechanism needs to be repaired, the rotating motor 9 can be started, and the rotating motor 9 will drive the threaded rod 10 to rotate. At this time, the threaded sleeve 14 will move horizontally, thereby moving the heat dissipation box 2 out from the bottom side of the control cabinet 4, so as to facilitate the maintenance personnel to repair the heat dissipation mechanism inside the heat dissipation box 2, thereby improving the maintenance efficiency. When the interior of the control cabinet 4 needs to be cooled, the drive motor 13 is started, and the drive motor 13 will drive the driving wheel 15 to rotate. With the cooperation of the driving wheel 15 and the multiple driven wheels 16, the multiple rotating rods 17 will rotate. Driven by the rotating rod 17, the multiple rotating blades 18 installed on the outside of the rotating rod 17 will rotate, thereby forming wind force, and the wind is blown into the interior of the control cabinet 4 through the multiple heat dissipation holes 7 opened at the bottom of the heat dissipation box 2, so that the hydraulic control system 6 can be cooled.

[0024] Example 2

[0025] like Figure 1 - Figure 6As shown, a hydraulic control device includes a heat sink 2, and a refrigeration mechanism is installed inside the heat sink 2. The refrigeration mechanism includes two mounting plates 19 that can be detachably installed inside the heat sink 2. Since the mounting plates 19 can be detachably installed inside the heat sink 2, it is not only convenient to replace the refrigeration mechanism when it is damaged, but also convenient to disassemble it when the heat sink mechanism needs to be repaired. There are two connecting pipes 20 installed on the top of the two mounting plates 19, multiple refrigeration pipes 21 installed between the two connecting pipes 20, and a circulating pump 22 and a refrigerator 23 placed on the inner wall of the bottom of the heat sink 2. Coolant is injected into the multiple refrigeration pipes 21, and the inlet of the circulating pump 22 is connected to one of the connecting pipes 20 through a water inlet pipe, and the outlet of the circulating pump 22 is connected to the inlet of the refrigerator 23 through a water outlet pipe, and the outlet of the refrigerator 23 is connected to the other connecting pipe 20 through a connecting pipe.

[0026] It should be noted that, when this hydraulic control device is in use and the heat dissipation mechanism is blowing air, the circulation pump 22 and the refrigerator 23 are started. Under the action of the circulation pump 22, the coolant inside the multiple refrigeration pipes 21 will be continuously cooled through the refrigerator 23, and the coolant after cooling will be continuously circulated inside the multiple refrigeration pipes 21. Since the refrigeration mechanism is located above the heat dissipation mechanism, when the heat dissipation mechanism is blowing air, the blown air will pass through the multiple refrigeration pipes 21. Under the action of the heat exchange of the refrigeration pipes 21, the blown air will become cold air, which can further effectively dissipate the heat of the hydraulic control system 6, improve the heat dissipation efficiency, and make it more convenient for people to use.

[0027] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
