Description

Technical Field

[0001] The embodiments of this utility model belong to the field of car wash machine maintenance technology, and more specifically, relate to a disassembly tool for the brush group motor of a high-speed train car wash machine. Background Technology

[0002] In the daily operation and maintenance system of high-speed trains, the car wash machine plays a crucial role in maintaining the cleanliness of the train's exterior. Its brush motor, as the core power source driving the brushes for efficient washing, operates under high load and high frequency for extended periods in harsh environments, making it highly susceptible to failure due to wear, aging, and overload. If the brush motor malfunctions, such as failing to start, unstable speed, or excessive noise, it directly affects the efficiency of the car wash machine's brushes, resulting in poor cleaning of the high-speed train and potentially impacting the train's appearance and subsequent safe operation. Therefore, timely disassembly of faulty or maintenance-required brush motors for repair and parts replacement is crucial for ensuring the stable operation of the car wash machine and maintaining the high-speed train's good appearance and operational condition.

[0003] In existing technologies, the disassembly of the brush assembly motor of a high-speed train car wash typically involves a professional technician first developing a preliminary disassembly procedure based on the motor's model and structure. After implementing safety measures such as power disconnection and warning signs, conventional tools like screwdrivers and wrenches are used to sequentially disconnect the external wiring connecting the motor to the power supply, carefully marking the wiring to prevent confusion during subsequent installation. Next, the couplings and pulleys connecting the motor to the brush assembly transmission device are disassembled. For some tightly connected components, auxiliary tools such as pullers are required. Subsequently, the fastening bolts of the front and rear end covers of the motor are loosened, and attempts are made to separate the end covers from the motor body. If the end covers are tightly attached to the base, tools such as chisels and hammers are used to gently tap them to gradually detach the end covers. Finally, ensuring safety, the motor rotor is carefully extracted manually or with the aid of small lifting equipment.

[0004] However, existing disassembly techniques have many drawbacks. Firstly, the entire disassembly process relies heavily on manual operation, requiring highly experienced and skilled technicians. The process is cumbersome and time-consuming, significantly impacting the downtime for car wash machine maintenance and reducing overall equipment efficiency. Secondly, when disassembling tightly connected components such as couplings and end caps, traditional methods like hammering and prying with chisels can easily cause mechanical damage to precision components such as the motor housing, internal windings, and bearings due to improper force, further shortening the motor's lifespan and increasing maintenance costs. Utility Model Content

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a disassembly fixture for the brush assembly motor of a high-speed train car wash machine. The motor coupling is placed below a clamping plate, with the bottom surface of the plate in contact with the coupling. The position is then adjusted so that the brush shaft is placed in a U-shaped groove. A jack is used to push the brush shaft out of the coupling. At this point, the clamping plate vertically limits the coupling, and the base plate vertically limits the jack. Under the action of the jack, the brush shaft can quickly and smoothly detach from the coupling, thus completing the motor disassembly operation.

[0006] To achieve the above objectives, this utility model provides a disassembly tool for the motor of the brush assembly of a high-speed train car wash machine, comprising: a base plate and a clamping plate, wherein the base plate and the clamping plate are connected by a screw rod; The base plate is a square plate, and multiple lead screws are provided, with their bottom ends fixed to the four corners of the base plate, and their surfaces are threaded. The card plate is a square plate with the same specifications as the base plate. It has round through holes at its four corners corresponding to the position of the lead screw. It is fitted onto the lead screw through the round through holes and moves along the axial direction of the lead screw. The card plate is arranged parallel to the base plate, and the distance between it and the base plate can be adjusted by adjusting the nut; The side of the card plate has a U-shaped groove, and the base plate is also equipped with a jack.

[0007] Furthermore, the top surface of the card plate is also provided with a limiting plate to limit the position of the fixing plate.

[0008] Furthermore, the adjusting nut is located above the top surface of the clamping plate and is connected to the lead screw via a thread.

[0009] Furthermore, the U-shaped groove is configured in multiple stages with the width decreasing progressively from the edge of the card plate to the depth, and the center of each U-shaped groove is at the same position.

[0010] Furthermore, the four corners of the base plate are also provided with through holes corresponding to the positions of the lead screw. The lead screw passes through the through holes of the base plate in the opposite direction, and the bottom end of the lead screw is a bolt head, which is placed on the back of the base plate as a foot pad.

[0011] Furthermore, the lead screw is also provided with a fixing nut, which is located above the top surface of the base plate.

[0012] Furthermore, it also includes the top shaft block; The top shaft block is located at the output end of the jack, with its bottom end in contact with the jack and its top end in contact with the brush shaft.

[0013] Furthermore, the top shaft block has a three-section radius structure, with both the bottom and top ends being cylindrical structures, and the diameter of the bottom cylinder being larger than that of the top cylinder. The two cylinders are connected by a frustum of a cone.

[0014] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects: This utility model discloses a tooling for disassembling the motor of a car wash brush assembly. The motor coupling is placed below a clamping plate and in contact with the bottom surface of the clamping plate. The position is then adjusted so that the brush shaft is placed in a U-shaped groove. The brush shaft is then pushed out of the coupling using a jack. At this time, the clamping plate limits the vertical movement of the coupling, and the base plate limits the vertical movement of the jack. Under the action of the jack, the brush shaft can quickly and smoothly detach from the coupling, thereby completing the disassembly of the motor.

[0015] The utility model discloses a disassembly fixture for a car wash machine brush assembly motor. An adjusting nut is located above the top surface of the clamping plate and is connected to the lead screw via a thread. By adjusting the height of the adjusting nut on the lead screw, the upper limit of the clamping plate height can be changed, thereby adjusting the distance between the clamping plate and the base plate.

[0016] This utility model discloses a disassembly fixture for a car wash machine brush assembly motor. An adjusting nut is located above the top surface of the clamping plate. The large-radius cylinder at the bottom of the top shaft block is positioned at the output end of the jack, providing a large contact surface and ensuring the top shaft block is stably placed on the jack. The small-radius cylinder at the top of the top shaft block achieves a diameter change, allowing the jack's output force to be smoothly transmitted to the brush shaft, pushing it out. This avoids a situation where the jack's output diameter is larger than the brush shaft diameter, preventing the brush shaft from being pushed out. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] In the actual field environment, the motor 8 is horizontally fixed to the fixing plate 11. The output shaft of the motor 8 is connected to the brush shaft 10 of the brush disc 12 via a coupling 9. The coupling 9 transmits the power from the horizontally rotating output shaft of the motor 8 to the vertically rotating brush shaft 10, thereby driving the brush disc 12 to rotate. Brush heads are coiled on the brush disc 12. When the motor 8 starts, it drives the brush heads to rotate to clean the train body. When the motor 8 needs maintenance, it needs to be removed. Simply disconnecting the brush shaft 10 from the coupling 9 completes the overall disassembly of the motor 8 without damaging other components. This embodiment of the invention allows for the direct ejection of the brush shaft 10 from the coupling 9, thereby achieving a quick, efficient, and safe disassembly of the motor 8.

[0021] like Figure 1-4 As shown in the figure, this utility model embodiment provides a disassembly fixture for the brush assembly motor of a high-speed train car wash, including: a base plate 1 and a clamping plate 2, which are connected by lead screws 3. The base plate 1 is a square plate, and multiple lead screws 3 are provided, with their bottom ends fixed at the four corners of the base plate 1, and their surfaces are threaded. The clamping plate 2 is a square plate with the same specifications as the base plate 1, and its four corners have through holes corresponding to the positions of the lead screws 3. It is fitted onto the lead screws 3 through these through holes and moves along the axial direction of the lead screws 3. The clamping plate 2 is arranged parallel to the base plate 1, and the distance between it and the base plate 1 is adjusted by adjusting nuts 5. The side of the clamping plate 2 has a U-shaped groove 201, and the base plate 1 is also provided with a jack 6. In use, place the coupling 9 of the motor 8 below the clamping plate 2 and make it contact the bottom surface of the clamping plate 2. Then adjust the position so that the brush shaft 10 is placed in the U-shaped groove 201. Use the jack 6 to push the brush shaft 10 out of the coupling 9. At this time, the clamping plate 2 limits the coupling 9 in the vertical direction, and the base plate 1 limits the jack 6 in the vertical direction. Under the action of the jack 6, the brush shaft 10 can quickly and smoothly disengage from the coupling 9, thereby completing the disassembly of the motor 8.

[0022] As a further preferred embodiment, since the specifications of the motor 8 are different, the corresponding specifications of the coupling 9 and brush shaft 10 are also different. In order to enable the disassembly fixture of this utility model to adapt to the requirements of couplings 9 and brush shafts 10 of different specifications, the U-shaped groove 201 is set in multiple stages with the width decreasing from the edge of the clamping plate 2 to the depth, and the center of each U-shaped groove 201 is at the same position, ensuring that the coupling 9 can be clamped by the clamping plate 2 and the brush shaft 10 can pass smoothly through the U-shaped groove 201, so that this fixture can adapt to couplings 9 and brush shafts 10 of different sizes.

[0023] The top surface of the card plate 2 is also provided with a limiting plate 202 to limit the fixing plate 11 and prevent the brush shaft 10 from going too deep and scraping against the groove wall of the U-shaped groove 201, causing damage to the brush shaft 10.

[0024] The adjusting nut 5 is located above the top surface of the clamping plate 2 and is connected to the lead screw 3 by a thread. By adjusting the height of the adjusting nut 5 on the lead screw 3, the upper limit of the height of the clamping plate 2 can be changed, thereby adjusting the distance between the clamping plate 2 and the base plate 1.

[0025] Understandably, by adjusting the nut 5 to limit the upward movement of the clamping plate 2, the brush shaft 10 can be pushed upward smoothly, thus disengaging the brush shaft 10 from the coupling 9.

[0026] The base plate 1 has through holes at its four corners corresponding to the positions of the lead screw 3. The lead screw 3 passes through the through holes of the base plate 1 in the opposite direction. The bottom end of the lead screw 3 is a bolt head, which is placed on the back of the base plate 1 as a foot pad. When the base plate 1 is placed on the ground, it prevents any protrusions on the ground from interfering with the stability of the base plate 1. By adjusting the position of the base plate 1, all the foot pads are placed on the ground to support it, thus avoiding shaking when the motor 8 of the brush assembly is disassembled.

[0027] The lead screw 3 is also provided with a fixing nut 4, which is located above the top surface of the base plate 1. The base plate 1 is fixed by tightening the fixing nut 4 downwards.

[0028] like Figure 5 As shown in the figure, a disassembly fixture for the brush assembly motor of a high-speed train car wash according to an embodiment of the present invention also includes a top shaft block 7. The top shaft block 7 is a single unit located at the output end of the jack 6. Its bottom end is attached to the jack 6, and its top end is attached to the brush shaft 10, but it is not connected to the jack 6. The top shaft block 7 has a three-section structure with its bottom and top ends being cylindrical structures. The diameter of the bottom cylinder is larger than that of the top cylinder, and the two cylinders are connected by a frustum conical.

[0029] Understandably, the large-radius cylinder at the bottom of the top shaft block 7 is positioned at the output end of the jack 6, providing a large contact surface and ensuring the top shaft block 7 is stably placed on the jack 6. The small-radius cylinder at the top of the top shaft block 7 achieves a diameter change, allowing the output force of the jack 6 to be smoothly transmitted to the brush shaft 10, pushing the brush shaft 10 out. This avoids a situation where the diameter of the output end of the jack 6 is larger than the diameter of the brush shaft 10, preventing the brush shaft 10 from being pushed out.

[0030] The jack 6 is a separate ultra-thin hydraulic jack, including an electric drive, a hydraulic oil tank, a high-pressure oil pump, a control valve group, and a pressure gauge component: the electric drive high-pressure oil pump draws hydraulic oil from the oil tank, and after being pressurized by the pump, it forms high-pressure oil; the control valve group is responsible for regulating the pressure, flow direction, and on / off of the oil, limiting the maximum pressure through the relief valve to ensure safety, and controlling the direction of oil entering and leaving the actuator through the reversing valve to achieve lifting or lowering actions; the pressure gauge displays the system pressure in real time, making it convenient for operators to monitor the load status and avoid the risk of overload.

[0031] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
