[0015] To make the above objects, features, and advantages of the present invention clearer, the following will describe specific embodiments of the present invention in detail while referring to the drawings of the specification.

[0016] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Next, as used herein, "an embodiment" or "embodiments" refer to specific features, structures, or characteristics that may be included in at least one embodiment of the present invention. The appearances of "in one embodiment" in different parts of this specification do not all refer to the same embodiment, nor are they mutually exclusive embodiments alone or selectively with other embodiments.

[0018] Furthermore, next, the present invention will be described in detail while referring to schematic diagrams. When describing embodiments of the present invention in detail, for the sake of facilitating the description, cross-sectional views showing the device structure are not partially enlarged according to a general ratio, and the schematic diagrams are merely illustrative and do not limit the protection scope of the present invention. Also, in actual manufacturing, three-dimensional spatial dimensions including length, width, and depth should be included.

[0019] Embodiment 1 Referring to Figures 1 to 6, these figures represent a first embodiment of the present invention, providing a ground hydraulic station for a car damper, which includes a hydraulic member 100 and a pipeline winding member 200. The hydraulic member 100 includes a protective case 101, a hydraulic pump 102 mounted inside the protective case 101, and a valve station 103 used in conjunction with the hydraulic pump 102. Both the hydraulic pump 102 and the valve station 103 are connected via a pipeline 104 to the hydraulic telescopic cylinder of the car damper and are used to control the operation of the car damper. The pipeline winding member 200 includes a plurality of winding assemblies attached to the hydraulic member 100 and removably mounted on the outer wall of the protective case 101, each winding assembly including a frame 201 and a winding wheel 202 attached to the frame 201 for automatically winding the pipeline 104, the winding wheel 202 being provided with a clamp 203 for gripping the pipeline 104 using centrifugal force.

[0020] Furthermore, the hydraulic component 100 includes a protective case 101, above which an oil tank 105 is provided. The oil tank 105 and the hydraulic pump 102 are connected via a pipeline 104 and an oil absorption assembly 106, and the oil tank 105 is fitted with a liquid level gauge, an air filter, a liquid level relay, and an oil return filter for control. The valve station includes a pressure gauge, a heater, an air cooler, a high-pressure filter, and a temperature transmitter, and is used to process and detect the hydraulic fluid and regulate its flow rate and pressure.

[0021] The specific operating process of the car damper's hydraulic system is as follows: The hydraulic pump 102 supplies hydraulic fluid, drawing it in from the oil tank 105 and generating the necessary hydraulic energy for the system through pressure. The hydraulic fluid enters the hydraulic valve, where its flow rate and pressure are controlled, transmitting the hydraulic energy to the actuator. The hydraulic valve controls the hydraulic energy, adjusting the flow rate and pressure of the hydraulic energy based on operator commands or signals from the automatic control system. The hydraulic energy is transmitted to the actuator. The hydraulic energy is transmitted to the operating members of the car damper, such as the car damper arm and the car damper bucket, via the actuator (hydraulic telescopic cylinder or hydraulic motor). The actuator operates, and based on the action of the hydraulic energy, the actuator completes the car damper's operating tasks, such as lifting or rotating the car damper arm, or lifting or tilting the car damper bucket. The hydraulic fluid returns to the oil tank 105, and the hydraulic fluid that has passed through the actuator returns to the oil tank 105 for recirculation and reuse.

[0022] In the overall operating process, the hydraulic pump 102, hydraulic valves, actuators, and hydraulic oil tank 105 are connected via hydraulic lines to form a single closed hydraulic system. The hydraulic pump 102 provides hydraulic energy. The hydraulic valves control the flow rate and pressure of the hydraulic energy. The actuators receive the hydraulic energy to complete the operating task. The oil tank 105 provides storage and cooling for the hydraulic fluid. With rational control and adjustment, the car damper's hydraulic system can achieve highly efficient and precise operation.

[0023] In this application, the hydraulic station of the car damper body is modified to move the hydraulic system of the car damper body from the body to nearby ground, and is installed in a sealed location. The specific modification includes the following steps: the pump station and valve station adopt an integrated structure and are mounted on the ground near the car damper body, and the car damper does not have an electromagnetic valve control box or hydraulic substation. The ground hydraulic station includes an oil tank, an oil tank with a volume of 1200L, an oil pump, a motor (22kW), an integrated block, various hydraulic valves, an oil filter, a balance cylinder, a hydraulic station base, etc. The hydraulic station adopts an integrated press beam, back plate, and hydraulic lock control circuit. The oil pump in the hydraulic station is a plunger pump, and the hydraulic station requires a fully sealed structure, is well sealed, and is waterproof and dustproof. The hydraulic pipeline (on-site lofting installation of the pipeline) in the car damper body is rearranged and installed, an on-machine hydraulic bracket and a rotating chain train are added, and the connection between the ground hydraulic station and the oil pipe of the car damper body is made on-machine using a high-pressure hose. To avoid wear due to interference friction between the high-pressure hose and the on-machine cable, an on-machine high-pressure hose guide groove must be installed inside the end ring of the vehicle outlet end of the car damper body. The high-pressure hose bracket is mounted on the ground outside the end ring of the vehicle outlet end of the car damper body, and the on-machine high-pressure hose is laid through the bracket in the guide groove inside the end ring of the vehicle outlet end of the car damper body. The control functions of the control panel are modified, and after modification, the control panel can monitor parameters such as the operating status of the hydraulic station motor and system pressure, and the operation of the system, so as to meet the requirements for safe operation on site. The power cable of the hydraulic station heater in the original car damper body is removed, and signal cables such as solenoid valves and oil temperature are removed. A new cable bridge will be laid from the hydraulic station to the power distribution room of the car damper, and a new cable bridge will be laid from the hydraulic station to the PLC control box.Depending on the actual site conditions, the power cable, control cable, and associated components will be laid again from the ground connection box (vehicle inlet end) of the car damper unit to the ground hydraulic station (vehicle exit end). The oil pump motor cable and circulation pump cable will be newly laid from the hydraulic station to the control box of the car damper unit, and the control cable from the hydraulic station to the PLC control box will be newly laid. The low-pressure distribution element will be installed inside the control box of the car damper unit, and the buttons and support lamps on the control panel will be installed. The power and control cables for the hydraulic station will be newly connected. The flexible cable for the rotating part of the car damper unit will be laid again and wired. The control logic of the hydraulic station of the car damper unit will be added and modified. Electrical wiring, hydraulic adjustment, and electrical adjustment will be performed on the modified hydraulic station. The entire modified car damper system will be adjusted.

[0024] This invention provides a novel system that ensures the absence of dust and water vapor, automatically controls the temperature, is easily and rationally positioned without spatial limitations, and facilitates inspection and repair. High-pressure hoses and drag chains are used to connect the ground-based oil source, valve group, and balance cylinder to the main hydraulic cylinder and hydraulic lock. A pipeline winding member 200 automatically winds and unwinds the pipeline 104 between the car damper body and the hydraulic member 100, adapting to the movement of the car damper body. This not only fulfills the functional needs but also improves the reliability and maintainability of the system, reducing maintenance and operating costs. This eliminates potential equipment damage and serious accidents that can occur in car dampers, lays a solid foundation for reliable and stable long-term operation of car damper systems in power generation companies, and reduces the company's maintenance costs.

[0025] Example 2 Referring to Figures 6 to 13, these figures represent a second embodiment of the present invention, which differs from the first embodiment in the following ways: it is a ground hydraulic station for a car damper, in which the frame 201 includes an intermediate bracket 201a and two side frames 201b provided symmetrically with respect to the intermediate bracket 201a, each side frame 201b includes a side plate 201b-1 and three insertion rods 201b-2 attached to the side plate 201b-1, with each insertion rod 201b-2 in the two side frames 201b corresponding one-to-one, and the intermediate bracket 201a includes two triangular plates 201a-1 and three rotating drums 201a-2 connecting the two triangular plates 201a-1, with the rotating drums 201a-2 fitted onto the insertion rods 201b-2 and corresponding one-to-one with each insertion rod 201b-2. The distribution of the rotating drums 201a-2 and insertion rods 201b-2 is in an inverted triangle, with the two upper rods symmetrically positioned relative to the lower rod, and the winding wheel 202 is positioned on the two upper rotating drums 201a-2. A gear 204 is attached to the lower rotating drum 201a-2, and a powerful spring 204a is provided inside the gear 204. The annular teeth 202c of the winding wheel 202 mesh with the gear 204 and are used to drive and rotate the winding wheel 202.

[0026] Furthermore, in the process of improving the movement of the hydraulic member 100 of the car damper, it is necessary to adapt to the situation in which the pipeline 104 between the hydraulic member 100 fixed to the ground and the moving car damper body is prone to entanglement or wear due to being pulled and moved. Therefore, a pipeline winding member 200 is provided for this part of the pipeline 104 to perform self-adaptive winding and unwinding, making it easier to cooperate with the operation of the car damper.

[0027] Furthermore, the reason for providing two symmetrical side frames 201b on both sides of the intermediate bracket 201a is that the side frames 201b can be assembled by simple insertion, and each time a winding wheel 202 is added, one side frame 201b and one intermediate bracket 201a must be added to one side of it to form the original other side frame 201b and one new frame 201. Rapid insertion and assembly enables the interlocking of multiple sets of winding assemblies to form a large winding member, thereby accommodating the needs of different numbers of pipelines 104.

[0028] Furthermore, three insertion rods 201b-2 are provided on each side frame 201b, and three rotating drums 201a-2 are provided on the intermediate bracket 201a, with one-to-one correspondence between the three insertion rods 201b-2 and the lower two being symmetrically positioned relative to the lower one. The reason for this is that the lower insertion rod 201b-2 and the rotating drum 201a-2 are used to support the gear 204 and the powerful spring 204a, and are used for the rotation of the gear 204, while the two upper insertion rods 201b-2 and the rotating drums 201a-2 support the winding wheel 202, and also wind the The eel 202 is used to define the gear, so that the annular teeth 202c in the winding wheel 202 mesh with the gear 204, so that when the pipeline 104 is pulled out, the winding wheel 202 drives the gear 204 to rotate, thereby driving the powerful spring 204a to contract, and conversely, when the pipeline 104 is left unwinding, the powerful spring 204a drives the gear 204 to rotate, further driving the winding wheel 202 to wind up the pipeline 104, thereby achieving self-adaptive winding and unwinding of the pipeline 104.

[0029] A symmetrical first rotating wheel 201a-3 is provided on one side of two triangular plates 201a-1, and a rectangular groove 201a-4 is provided on the other side. A trapezoidal block 201a-5 is slidably mounted within the rectangular groove 201a-4, and a first spring 201a-6 is provided between the trapezoidal block 201a-5 and the rectangular groove 201a-4 to drive and return the trapezoidal block 201a-5. The trapezoidal block 201a-5 has an upward-facing slope, and a second rotating wheel 201a-7 is provided on its side. A retractable wedge-shaped plate 201a-8 is provided within the trapezoidal block 201a-5, positioned above the second rotating wheel 201a-7. The first rotating wheel 201a-3 and the second rotating wheel 201a-7 are each inserted into position-limiting ring grooves 202d opened in the outer wall of the winding wheel 202.

[0030] Furthermore, the intermediate bracket 201a is provided with two symmetrical triangular plates 201a-1, two symmetrical first rotating wheels 201a-3 are attached to one of the triangular plates 201a-1, and a slidable and pressable trapezoidal block 201a-5 is attached to the other triangular plate 201a-1, and a second rotating wheel 201a-7 is provided on the trapezoidal block 201a-5. The first rotating wheels 201a-3 and the second rotating wheels 201a-7 engage and lock the winding wheel 202 and are used for positioning the winding wheel 202, as well as for locking the winding wheel 202. Furthermore, both the first rotating wheel 201a-3 and the second rotating wheel 201a-7 are inserted into the position-limiting ring groove 202d of the side baffle 202b of the winding wheel 202. In this way, when the winding wheel 202 rotates, the first rotating wheel 201a-3 and the second rotating wheel 201a-7 also rotate accordingly, without interfering with or affecting the rotation of the winding wheel 202.

[0031] Furthermore, a rectangular groove 201a-4 is provided in one of the triangular plates 201a-1, a trapezoidal block 201a-5 is slidably mounted within the rectangular groove 201a-4, an elongated hole is provided inside the trapezoidal block 201a-5, a slide rod is provided inside the rectangular groove 201a-4, and a first spring 201a-6 is provided inside the elongated hole so that the slide rod moves along the elongated hole and pushes the trapezoidal block 201a-5 forward. The reason the trapezoidal block 201a-5 has an upward-facing slope is that when the winding wheel 202 is positioned downwards, if the winding wheel 202 is positioned above the trapezoidal block 201a-5, it can push out the trapezoidal block 201a-5, preventing it from interfering with it. Furthermore, the action of the first spring 201a-6 pushes and moves the trapezoidal block 201a-5, pressing and locking the winding wheel 202.

[0032] Furthermore, the trapezoidal block 201a-5 is provided with a wedge-shaped plate 201a-8 that can be retracted inward, which is used to protect the second rotating wheel 201a-7 located below the wedge-shaped plate 201a-8, ensuring that the winding wheel 202 does not come into contact with the second rotating wheel 201a-7 when it is positioned downwards, and the second rotating wheel 201a-7 does not affect the downward movement of the winding wheel 202. When the winding wheel 202 has completely fallen onto the rotating drum 201a-2, the second rotating wheel 201a-7 is simultaneously inserted into the position-restricting ring groove 202d on the side of the winding wheel 202 by the action of the trapezoidal block 201a-5, and clamps the side of the winding wheel 202. At this time, the wedge-shaped plate 201a-8, by the action of its internal spring, has its front end in contact with the upper wall of the position-restricting ring groove 202d on the side of the winding wheel 202. Furthermore, a ball may be fitted to the front end of the wedge-shaped plate 201a-8, thereby the ball contacting the upper wall of the position-restricting ring groove 202d and reducing the frictional force between the wedge-shaped plate 201a-8 and the position-restricting ring groove 202d on the side of the winding wheel 202.

[0033] In this embodiment, first, each rotating drum 201a-2 of the intermediate bracket 201a is aligned one-to-one with each insertion rod 201b-2 of one of the side frames 201b, and the insertion rod 201b-2 is inserted into the rotating drum 201a-2. Then, the insertion rod 201b-2 on the other side is aligned with the rotating drum 201a-2 of the intermediate bracket 201a, and the insertion rod 201b-2 is inserted into the rotating drum 201a-2 of the intermediate bracket 201a, thereby completing the assembly of the frame 201.

[0034] Subsequently, when the winding wheel 202 is placed on the intermediate bracket 201a, and the winding wheel 202 is placed on the intermediate bracket 201a, and it is necessary to place the winding wheel 202 between the two triangular plates 201a-1 of the intermediate bracket 201a, first the winding wheel 202 is placed downwards, approaching one side of the triangular plate 201a-1 on which the trapezoidal block 201a-5 is provided, and the winding wheel 202 is then placed between the trapezoidal block 2 The inclined surface of 01a-5 is pressed, thereby causing the trapezoidal block 201a-5 to be pressed and move outward, simultaneously compressing the internal first spring 201a-6, and as the winding wheel 202 slides down from the inclined surface of the trapezoidal block 201a-5 and the upper surface of the wedge-shaped plate 201a-8, the trapezoidal block 201a-5 is positioned on the side of the winding wheel 202 and presses against the winding wheel 202 from the side, and at this time the wedge-shaped plate 201a- 8 is pressed and contracts inward, exposing and protruding the second rotating wheel 201a-7, which is inserted into the position limiting ring groove 202d on the side of the winding wheel 202. At the same time, the trapezoidal block 201a-5, pressed by the internal first spring 201a-6, presses the winding wheel 202 from the side, thereby pressing the other side of the winding wheel 202 against the first rotating wheel 201a-3, and inserting the first rotating wheel 201a-3 into the position limiting ring groove 202d of the other side baffle 202b, thereby achieving simple locking on both sides of the winding wheel 202. Furthermore, since an annular tooth 202c is provided on one side baffle 202b of the winding wheel 202, when the winding wheel 202 is positioned downward, the annular tooth 202c engages with the gear 204, thereby maintaining a meshed state between the winding wheel 202 and the gear 204.

[0035] The other components are the same as those in Example 1.

[0036] Example 3 Referring to Figures 6 to 13, these figures represent a third embodiment of the present invention, and the differences between this embodiment and the second embodiment are as follows: A ground hydraulic station for a car damper, wherein a through hole 202a is provided in the center of the winding wheel 202, a clamp 203 is provided on the through hole 202a and one of the side baffles 202b, an annular tooth 202c is provided on the other side baffle 202b, and position limiting ring grooves 202d are provided on the outer surfaces of both side baffles 202b. The clamp 203 includes a cavity 203a and a plurality of clamping plates 203b located in the cavity 203a, the plurality of clamping plates 203b distributed at equal intervals in an annular shape, a guide groove 203a-1 is provided on one surface of the inner wall of the cavity 203a, and a first bump 203b-1 is provided on one surface of the clamping plate 203b, the first bump 203b-1 is located in the guide groove 203a-1 As it moves along, a rotating disc 203c is provided within the cavity 203a, and the rotating disc 203c is positioned on the side away from the guide groove 203a-1 of the clamping plate 203b, a position limiting groove 203c-1 is provided in the rotating disc 203c, and a second bump 203b-2 is provided on the other surface of the clamping plate 203b, and the second bump 203b-2 slides along the position limiting groove 203c-1. Multiple ropes 203d are provided on the outer wall of the rotating disc 203c, and a weight ball 203e is provided at one end of each rope 203d.

[0037] In this embodiment, one end of the pipeline 104 is passed through the through hole 202a of the winding wheel 202, and this end is inserted into the hole of the side baffle 202b, after which the pipeline 104 is wound onto the outer wall of the winding wheel 202. When the pipeline 104 is pulled out and extended, the pipeline 104 drives the winding wheel 202 to rotate, and the winding wheel 202 tightens the powerful spring 204a by having its annular teeth 202c drive the gear 204 to rotate, while the rotation of the winding wheel 202 drives the weight ball 203e in the clamp 203 to rotate, and the weight ball 203e pulls the rope 203d outward, thereby pulling and rotating the turntable 203c, and the turntable 203c The rotation of the first bump 203b-1 is driven by the position limiting groove 203c-1 to rotate each second bump 203b-2, and the rotation of the second bumps 203b-2 drives the corresponding clamping plates 203b, causing the first bump 203b-1 to rotate along the guide groove 203a-1, so that each clamping plate 203b is brought together to clamp the pipeline 104 located therein, thus ensuring that when the pipeline 104 is pulled outward, only the pipeline 104 wound in the winding wheel 202 is pulled outward.

[0038] Conversely, when there is excess pipeline 104 that needs to be retrieved, the powerful spring 204a drives the gear 204 to rotate in the reverse direction and return it to its original position. The gear 204, via the annular teeth 202c, drives the winding wheel 202 to rotate in the reverse direction. The reverse rotation of the winding wheel 202 rewinds and retrieves pipeline 104, while simultaneously driving the weight ball 203e in the clamp 203 to rotate. The weight ball 203e drives the rope 203d to expand outward, thereby pulling the turntable 203c. The first bump 203b-1 rotates along the guide groove 203a-1, causing the first bump 203b-1 to rotate along the guide groove 203a-1, which in turn drives the second bumps 203b-2 to rotate, causing the second bumps 203b-2 to rotate along the guide groove 203a-1, which in turn brings the clamping plates 203b together to clamp the pipeline 104 located within them, thereby ensuring that when the pipeline 104 is recovered inward, only the excess pipeline 104 outside is recovered.

[0039] The winding wheel 202 rotates, generating centrifugal force. This centrifugal force causes the originally hanging weight ball 203e to rotate and move outwards, spreading outwards (similar to a "flying chair" in an amusement park). The rotation also pulls and rotates the turntable 203c, tightening and clamping it against the clamp 203, clamping the pipeline 104, and ensuring self-adaptive winding and unwinding of the excess pipeline 104. Conversely, when not rotating, each rope 203d and weight ball 203e automatically hangs down, reducing the clamping force against the clamp 203, making it easier to open the clamp 203 and further easier to attach the pipeline 104.

[0040] The other components are the same as those in Example 2.
