Description

Technical Field

[0001] This utility model relates to the field of braking device technology, and in particular to a high-efficiency hydraulic braking device. Background Technology

[0002] Hydraulic braking systems are systems that use fluid to transmit pressure to achieve braking, and are widely used in vehicles and equipment such as automobiles, motorcycles, and construction machinery.

[0003] Existing hydraulic braking devices typically use an oil pump to deliver hydraulic oil to a telescopic boom, controlling its extension and retraction, which in turn controls the movement of the brake disc to brake the equipment. However, the hydraulic oil generates a significant amount of heat when operating the boom, leading to a rise in hydraulic fluid temperature. Since the braking device lacks a cooling system, the high-temperature hydraulic oil negatively impacts the braking effect, resulting in poor braking performance. Furthermore, the brake disc is usually fixed to a mounting plate with multiple bolts, requiring operators to remove these bolts with a wrench for replacement, which is inconvenient. Therefore, we propose a high-efficiency hydraulic braking device. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-4 A high-efficiency hydraulic braking device includes a base 1, a control cabinet 30 mounted on the top of the base 1, and a controller inside the control cabinet 30. The controller is one of a control motherboard, a host computer, or a PLC logic controller.

[0029] like Figure 1 and Figure 2As shown, two strip-shaped connecting seats 12 are symmetrically installed on the top of the base 1. Each strip-shaped connecting seat 12 has a mounting bracket 8 rotatably connected to both ends via a connecting shaft. A fixing block 6 is installed on the top of each mounting bracket 8. A hydraulic telescopic rod 7 is provided between the two fixing blocks 6. Both ends of the hydraulic telescopic rod 7 are fixed to the side of the corresponding fixing block 6 via hinge seats. In actual use, the hydraulic telescopic rod 7 can push the two mounting brackets 8 to rotate along the connecting shaft, thereby adjusting the distance between the two mounting brackets 8.

[0030] like Figure 1 and Figure 4 As shown, each mounting bracket 8 is equipped with a mounting plate 9. The adjacent surfaces of two mounting plates 9 are connected to a connecting plate 13 through an adjustment mechanism. The specific structure of the adjustment mechanism is as follows: the adjustment mechanism includes an adjustment screw 11 rotatably connected to the side of the connecting plate 13. One end of the adjustment screw 11 passes through the corresponding mounting plate 9, and the adjustment screw 11 is threadedly connected to the corresponding mounting plate 9. By rotating the adjustment screw 11, the horizontal movement of the connecting plate 13 can be controlled, and the distance between the two connecting plates 13 can be adjusted as needed.

[0031] It should be noted that, as Figure 1 and Figure 2 As shown, each connecting plate 13 has several guide rods 10 installed on its side edge. One end of each guide rod 10 slides through the side of the corresponding mounting plate 9. Through the cooperation of the guide rods 10 and the mounting plate 9, the connecting plate 13 can be limited so that the connecting plate 13 will not rotate with the adjusting screw 11.

[0032] like Figure 1 and Figure 4 As shown, each connecting plate 13 has several limiting grooves 15 on its side. Each limiting groove 15 has a strip-shaped limiting block 14 slidably connected inside it. One side of each strip-shaped limiting block 14 extends outside the limiting groove 15, and the sides of the strip-shaped limiting blocks 14 on the same side are connected by a brake disc 17. In actual use, by inserting the strip-shaped limiting block 14 into the corresponding limiting groove 15, the brake disc 17 can be connected to the connecting plate 13. The connection is convenient, and the brake disc 17 can be used to brake the external mechanism.

[0033] like Figure 4As shown, several second positioning holes 27 are provided on the top of the connecting plate 13. Each second positioning hole 27 passes through the limiting groove 15, and several first positioning holes 19 are provided on the top of each strip-shaped limiting block 14. When the strip-shaped limiting block 14 is located in the limiting groove 15, the first positioning holes 19 and the second positioning holes 27 are aligned. Each second positioning hole 27 is provided with a positioning rod 26 inside. The bottom of each positioning rod 26 slides through the corresponding first positioning hole 19 and second positioning hole 27. In actual use, after the strip-shaped limiting block 14 moves to the preset position inside the limiting groove 15, the operator inserts the positioning rod 26 into the corresponding first positioning hole 19 and second positioning hole 27 to fix the strip-shaped limiting block 14 in the limiting groove 15, which is convenient.

[0034] It should be noted that, as Figure 4 As shown, each connecting plate 13 has a receiving groove 16 on its top. Each receiving groove 16 has a strip fixing plate 18 inside. The tops of the positioning rods 26 on the same side are connected to the corresponding strip fixing plates 18. Multiple positioning rods 26 can be fixed together by the strip fixing plates 18. In this way, multiple positioning rods 26 can be moved synchronously by simply moving the strip fixing plates 18, which is convenient.

[0035] like Figure 1 and Figure 2 As shown, two second oil supply pipes 5 are installed on the side of the hydraulic telescopic rod 7. The two second oil supply pipes 5 are connected by a control valve 29, and one end of one of the second oil supply pipes 5 is connected to the oil supply mechanism. The oil supply mechanism includes an oil storage tank 2 fixed on the top of the base 1. The bottom side of the oil storage tank 2 is connected to the oil inlet of the oil pump 28 through a pipe. The oil pump 28 is fixed on the top of the base 1, and the oil outlet of the oil pump 28 is connected to the end of the second oil supply pipe 5. The control valve 29 and the oil pump 28 are both connected to the controller through wires. In actual use, the controller can control the control valve 29 to work, so that the oil pump 28 can deliver the hydraulic oil in the oil storage tank 2 to the hydraulic telescopic rod 7 through one of the second oil supply pipes 5, thereby controlling the operation of the hydraulic telescopic rod 7.

[0036] like Figure 1 and Figure 3 As shown, one end of the second oil supply pipe 5 is fixed to the top of the cooling box 4. The cooling box 4 is fixed to the top of the base 1, and a heat exchange pipe 25 is installed inside the cooling box 4. One end of the second oil supply pipe 5 is fixed to the end of the heat exchange pipe 25, and the other end of the heat exchange pipe 25 is connected to the top of the oil storage tank 2 through the first oil supply pipe 3. In actual use, the controller can, as needed, use the control valve 29 to transport the hydraulic oil in the hydraulic telescopic rod 7 to the heat exchange pipe 25 through the other second oil supply pipe 5.

[0037] like Figure 3As shown, a partition 23 is installed inside the cooling box 4. Several cooling plates 24 are installed on the side of the partition 23. The cold end of each cooling plate 24 passes through the partition 23 and extends to one side of the heat exchange tube 25. The cooling plate 24 is connected to the controller through wires. In actual use, the cold end of the cooling plate 24 can cool the heat exchange tube 25, so that the hydraulic oil in the heat exchange tube 25 cools down during the flow. This keeps the hydraulic oil at a low temperature and improves the braking effect.

[0038] It should be noted that, as Figure 3 As shown, the heat exchange tube 25 is arranged in an "S" shape, which increases the length of the heat exchange tube 25 in the cooling box 4, extending the flow time of the hydraulic oil in the heat exchange tube 25 and improving the cooling effect.

[0039] like Figure 2 and Figure 3 As shown, an air inlet 21 is provided on one side of the cooling box 4. A fan 22 is installed inside the air inlet 21. The fan 22 is connected to the controller through a wire. The fan 22 blows air towards the hot end of the cooling chip 24. Several heat dissipation slots 20 are provided on both sides of the cooling box 4. The heat dissipation slots 20 are located between the air inlet 21 and the hot end of the cooling chip 24. During the operation of the cooling chip 24, the operator can control the fan 22 to work. The fan 22 blows the outside air towards the hot end of the cooling chip 24 to dissipate the heat. The air is then discharged into the external environment through the heat dissipation slots 20, which allows the cooling chip 24 to maintain normal operation.

[0040] Specifically, in use, the operator controls the control valve 29 and oil pump 28 via the controller. The oil pump 28 delivers hydraulic oil from the oil tank 2 to the hydraulic telescopic rod 7 via one of the second oil supply pipes 5. This controls the operation of the hydraulic telescopic rod 7, which in turn rotates the two mounting brackets 8 along the connecting shaft, causing the brake disc 17 to move. The side of the brake disc 17 then contacts the external equipment, braking it. After braking, the hydraulic oil in the hydraulic telescopic rod 7, under the action of the control valve 29, is delivered to the heat exchange tube 25 via another second oil supply pipe. The controller then controls the operation of the cooling element 24 and fan 22. The cold end of the cooling element 24 cools the hydraulic oil in the heat exchange tube 25, while the fan 22 blows outside air towards the hot end of the cooling element 24. The system dissipates heat, and the cooled air is discharged through the heat dissipation slot 20. The cooled hydraulic oil is then transported to the oil storage tank 2 through the first oil supply pipe 3, which keeps the hydraulic oil at a low temperature and improves the braking effect. When the brake disc 17 needs to be replaced, the operator can move the strip fixing plate 18 upwards. The strip fixing plate 18 will drive the positioning rod 26 to move, so that the positioning rod 26 disengages from the first positioning hole 19 and the second positioning hole 27. Then, the brake disc 17 is pulled to move the strip limiting block 14 out of the corresponding limiting groove 15. The strip limiting block 14 on the brake disc 17 is then inserted into the preset position in the unique limiting groove 15, so that the first positioning hole 19 and the second positioning hole 27 are aligned. Then, the positioning rod 26 is inserted into the corresponding first positioning hole 19 and the second positioning hole 27 to complete the fixing of the brake disc 17, and the replacement can be completed. The replacement is convenient.

[0041] Furthermore, a heat insulation pad is provided on the side of the partition 23 near the hot end of the cooling chip 24. The heat insulation pad is made of aerogel felt material or other materials with heat insulation properties. The heat insulation pad can separate the heat of the hot end of the cooling chip 24 from the cold end of the cooling chip 24, so that the heat of the hot end of the cooling chip 24 will not hinder the cooling effect of the cold end of the cooling chip 24.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
