Description

Technical Field

[0001] This utility model belongs to the field of wheel washing machine technology, specifically relating to a pit-type roller wheel washing machine. Background Technology

[0002] A wheel washing machine is a specialized piece of equipment for cleaning engineering vehicles, primarily used in construction sites, mines, and other similar locations. It can thoroughly wash the tires, chassis, and other parts of the vehicle, effectively removing attached mud, dust, and debris. This prevents engineering vehicles from carrying mud onto the road, reducing road pollution and improving the quality of the urban environment. It boasts advantages such as high automation, ease of operation, and labor savings.

[0003] Pit-type roller washing machines are a type of engineering wheel washing machine widely used in various construction sites. However, existing pit-type roller washing machines have many shortcomings in roller braking. Traditional mechanical braking methods are relatively simple, and in emergency braking situations, they may not be able to ensure that the rollers can stop rotating quickly and reliably due to long-term wear. This not only increases safety hazards during equipment operation but may also lead to damage to equipment components due to untimely braking, affecting the normal service life and working efficiency of the washing machine.

[0004] Therefore, a simpler and more reliable way is needed to solve the above problems. Utility Model Content

[0005] This utility model provides a pit-type roller washing machine to solve at least one of the above-mentioned technical problems.

[0006] The technical solution adopted by this utility model is as follows: a pit-type roller wheel washing machine, including a pit frame, a machine body, a rotating mechanism for supporting and driving the rotation of vehicle tires, and side baffles located on both sides of the rotating mechanism. The rotating mechanism has a drive gear and a roller. A gear braking mechanism is provided on the drive gear, and an electromagnetic braking mechanism is connected to the roller. The gear braking mechanism includes a backstop block located below the drive gear. One end of the backstop block is connected to a backstop seat via a pin, and the other end of the backstop block is connected to a spring mechanism that can push and pull the backstop block to mesh with the drive gear. The backstop seat is fixedly connected to the machine body. The electromagnetic braking mechanism includes electromagnetic brake discs installed at both ends of the roller and electromagnetic brake clamps fixedly connected to the machine body and disposed opposite to the electromagnetic brake discs.

[0007] Preferably, the rebound mechanism includes a pressure rod and a housing. The housing has a guide hole for the pressure rod to slide along the housing. The housing contains a spring and a rotating column. The spring is sleeved on the pressure rod. One end of the pressure rod is connected to the stop block by a screw, and the other end of the pressure rod is connected to the rotating column. The rotating column has curved grooves and recesses, the rotating column is connected to a connecting rod, the connecting rod is connected to a rotary button, and the surface of the connecting rod has protrusions that can cooperate with the curved grooves and recesses.

[0008] Preferably, the end of the backstop block that contacts the drive gear is provided with a wear-resistant and anti-slip layer, and the wear-resistant and anti-slip layer is made of high-strength rubber or polyurethane material.

[0009] Preferably, the electromagnetic brake disc has a hollow structure, the surface of the electromagnetic brake disc is provided with heat dissipation fins, and the inner side of the electromagnetic brake clamp is provided with a high-temperature resistant and wear-resistant magnetic friction plate.

[0010] Preferably, the side baffle is arc-shaped or straight.

[0011] Preferably, the machine body is provided with a mounting bracket for installing the electromagnetic brake clamp, and the mounting bracket is connected to the machine body by detachable fixing bolts.

[0012] Preferably, the mounting bracket is provided with multiple adjustment holes for adjusting the distance between the electromagnetic brake clamp and the electromagnetic brake disc.

[0013] Preferably, a shock-absorbing rubber sleeve is provided between the hub and the roller of the drive gear.

[0014] Preferably, the roller surface is provided with anti-slip texture.

[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. This utility model, on the one hand, utilizes the cooperation of the electromagnetic magnetic disk and the electromagnetic brake disk. When energized, the electromagnetic brake clamp generates magnetic force to clamp the electromagnetic brake disk, causing the roller to stop rotating quickly and providing efficient braking. On the other hand, in case of emergency or power failure, the push-pull spring mechanism causes the backstop block to engage with the drive gear, effectively preventing the drive gear from reversing and providing mechanical braking protection. This dual braking mechanism significantly improves the reliability and stability of the roller braking in the wheel washing machine, effectively meeting various braking needs, while enhancing equipment operation safety and improving work efficiency.

[0016] 2. In a preferred embodiment of this utility model, the spring-loaded mechanism is a key component of the gear braking mechanism. The pressure rod is slidably connected to the machine body, ensuring the smoothness and guidance of the pressure rod's movement, allowing the backstop block to accurately engage with the drive gear. The pressure rod and the backstop block are connected by screws, facilitating installation and disassembly, and aiding in later maintenance and replacement. A spring sleeved on the pressure rod provides stable and adjustable elastic force, ensuring that the backstop block reliably engages with the drive gear under different working conditions. The rotary button allows the operator to apply external force to control the backstop block. The protrusion of the pressure rod cooperates with the curved groove and recess of the rotating column, enabling positioning and limiting of the pressing part to prevent excessive movement. By utilizing the elastic force of the spring, the backstop block can be pushed and pulled sensitively to engage or disengage with the drive gear. When braking is required, the spring force pushes the pressure rod, thereby causing the backstop block to quickly engage with the drive gear, achieving braking; when the brake is released, external force overcomes the spring force, causing the backstop block to disengage from the drive gear. The inclusion of a rebound mechanism can meet the diverse needs of wheel washing machines in terms of rebound mechanism performance, cost, and maintenance difficulty, thereby improving the adaptability and customizability of the wheel washing machine.

[0017] 3. In a preferred embodiment of this utility model, by providing a wear-resistant and anti-slip layer at the end of the backstop block that contacts the drive gear, and making it from high-strength rubber or polyurethane material, the friction between the backstop block and the drive gear can be greatly enhanced. This ensures that the backstop block and the drive gear can mesh tightly during braking, preventing slippage and thus improving braking performance. Simultaneously, the wear-resistant material effectively reduces the wear at the contact point between the backstop block and the drive gear, extending the service life of both the backstop block and the drive gear, reducing equipment maintenance and replacement costs caused by frequent wear, and improving the overall durability and stability of the wheel washing machine.

[0018] 4. In a preferred embodiment of this utility model, the electromagnetic brake disc adopts a hollow structure, which reduces its own weight while ensuring structural strength, thereby reducing the additional load on the roller and improving the flexibility and efficiency of roller rotation. Furthermore, the anti-slip texture on the roller surface increases the friction between the roller and the vehicle tire, ensuring stable rotation of the vehicle tire on the roller and preventing slippage. This improves the stability and reliability of the cleaning process, ensuring that the wheel washing machine can efficiently and stably complete the cleaning of engineering vehicles.

[0019] The electromagnetic brake disc features heat dissipation fins evenly distributed along its circumference, significantly increasing the heat dissipation area. This allows for rapid dissipation of heat generated during electromagnetic braking, effectively preventing performance degradation due to overheating, extending its service life, and ensuring long-term stable operation of the electromagnetic braking device. The high-temperature resistant and wear-resistant magnetic friction pads inside the electromagnetic brake clamp enhance the friction between the clamp and the disc, improving the braking effect. Their high-temperature and wear-resistant properties also ensure stable performance during frequent braking, reducing wear and replacement frequency and lowering maintenance costs.

[0020] 5. As a preferred embodiment of this utility model, the side baffle is designed to be either arc-shaped or straight, providing users with the flexibility to choose according to actual usage scenarios and needs. The arc-shaped side baffle can better guide the water flow generated during vehicle washing, concentrating it towards the washing area, improving washing efficiency, and reducing water splashing to the outside of the baffle, effectively maintaining a clean and tidy working environment. The straight side baffle is structurally simpler, easier to install, and lower in cost, suitable for scenarios where water flow guidance requirements are not high, but cost control and space layout are important. This diverse design meets the different needs of different engineering sites for wheel washing machine side baffles, improving the versatility of the wheel washing machine.

[0021] 6. As a preferred embodiment of this utility model, the mounting bracket provided on the machine body can be connected to the machine body by detachable fixing bolts, which greatly facilitates the installation, debugging and maintenance of the electromagnetic brake clamp. It can easily and quickly fix the electromagnetic brake clamp in a suitable position. If it is necessary to adjust the position or angle of the electromagnetic brake clamp, it can be easily disassembled for fine adjustment. If the electromagnetic brake clamp malfunctions or wears out, it can be quickly removed for repair or replacement, which effectively shortens the equipment maintenance time, reduces the maintenance difficulty, improves the maintainability of the wheel washing machine, and ensures that the equipment can operate continuously and stably.

[0022] Furthermore, the multiple adjustment holes on the mounting bracket enhance the flexibility and precision of the electromagnetic brake clamp installation. By adjusting the alignment of the adjustment holes with the fixing bolts, the distance between the electromagnetic brake clamp and the electromagnetic brake disc can be precisely adjusted to achieve the best braking effect. This allows operators to easily adjust the distance according to actual conditions, ensuring that the electromagnetic braking device always maintains good working condition and improving the adaptability and reliability of the wheel washing machine braking system.

[0023] 7. In a preferred embodiment of this utility model, a shock-absorbing rubber sleeve is provided between the hub of the drive gear and the roller, which can effectively reduce the vibration generated during braking transmitted to the roller. During braking, the drive gear generates a large impact force when it meshes with the backstop block. This impact force can easily cause vibration and be transmitted to the roller. Long-term accumulation may lead to damage to the roller and other components. The shock-absorbing rubber sleeve has good elasticity and cushioning performance, which can absorb and disperse this vibration energy, protect the roller and other connected components from vibration damage, extend the service life of various components of the equipment, reduce noise during equipment operation, and improve the stability and comfort of equipment operation.

[0025] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0027] Furthermore, it should be understood in the description of this utility model that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a pit-type roller washing machine has a body 2 welded above a pit frame 1. Side baffles 3 are installed on both sides of the body 2. The side baffles 3 are arc-shaped to better guide the water flow and reduce water splashing. A rotating mechanism 4 for supporting and driving the vehicle tires is installed above the body 2. The rotating mechanism 4 includes two grid plates 41 and eight rollers 42. The grid plates 41 are respectively provided with first rollers 421 and second rollers 422 on both sides. After the sensing device 106 senses the car entering, it drives the four wheels to rotate. The rollers 422 are mounted on the second rollers 422. Equipped with a drive gear 5, the chain 105 on the drive gear 5 can drive the rollers 42 to rotate. Electromagnetic brake discs 8 are fixedly connected to the eight rollers 42 to ensure that the electromagnetic brake discs 8 and the rollers 42 rotate synchronously. Electromagnetic brake clips 91 are installed on the body 2 opposite to the electromagnetic brake discs 8 via a mounting bracket 9. When the car enters or exits and the rollers 42 need to be braked, the electromagnetic brake clips 91 are energized to generate magnetic attraction to the electromagnetic brake discs 8. The magnetic friction pads 911 are tightly attached to the electromagnetic brake discs 8 to achieve rapid braking, save time, and improve braking efficiency.

[0031] In addition, a gear braking mechanism 6 is installed below the drive gear 5. The backstop block 61 is part of the gear braking mechanism 6. One end of the backstop block 61 is connected to the backstop seat 63 fixed on the machine body 2 through the pin 62, and the other end is connected to the spring mechanism 7, which can push and pull the backstop block 61 to mesh with the drive gear 5. When the electromagnetic braking cannot be performed due to faults such as system power failure or wear of the electromagnetic brake disc 8, the backstop block 61 and the drive gear 5 are quickly meshed under the push of the spring mechanism 7, which can simply, quickly and effectively perform emergency braking on the roller 42.

[0032] Example 2 like Figure 5 , Figure 6As shown, a pit-type roller washing machine, differing from Embodiment 1, includes a spring mechanism 7 comprising a cylindrical pressure rod 71, a spring 72, and a housing 73. One end of the pressure rod 71 passes through a guide hole 10 on the machine body 2, forming a sliding connection with the machine body 2. The end of the pressure rod 71 near the backstop block 61 is connected to the backstop block 61 by a screw 11. The spring 72 is sleeved on the pressure rod 71, with one end abutting against the machine body 2, providing a restoring force for the pressure rod 71. The other end of the spring 72 is connected to a rotating column 74. The rotating column 74 is hollow inside and has a curved groove 741 on its surface. The curved groove 741 has a groove 742 and is slidably connected to a connecting rod 75. The connecting rod 75 has a protrusion 751 that can cooperate with the groove 742 and the curved groove 741. The outer casing 73 is fitted over the pressure rod 71, spring 72, and rotating column 74 to protect the internal structure. A rotary button 76 is connected to the side of the connecting rod 75 facing away from the rotating column 74. Rotating the rotary button 76 allows the connecting rod 75 to slide along the curved groove 741 until the protrusion 751 engages with the groove 742. At this point, the spring 72 compresses and pushes out the pressure rod 71, thereby pushing the backstop block 61 to engage with the drive gear 5. The elastic deformation (compression and tension) of the spring 72 converts external force into elastic potential energy, and the energy is quickly released after the external force disappears, achieving automatic reset. This allows for effortless and quick precise control of the backstop block 61, thus achieving emergency braking.

[0033] Example 3 like Figure 7 As shown, the electromagnetic brake disc 8 and roller 42 of a pit-type roller wheel washer differ from those in Embodiment 1. The roller 42 has a diameter of 50mm and an anti-slip texture 423 on its surface, which increases the friction between the roller 42 and the vehicle tire, effectively preventing tire slippage and fixing the cleaning position to improve the cleaning effect. The electromagnetic brake disc 8 adopts a hollow structure design, with a circular hollow cavity 81 in the center of the disc body. The hollow cavity 81 and the roller 42 can be fitted with a clearance. The hollow cavity 81 is sleeved on the roller 42. Multiple circular flow holes 82 with a diameter of 10mm are evenly distributed around the hollow cavity 81 for air circulation and heat dissipation. On the outer surface of the electromagnetic brake disc 8, multiple heat dissipation fins 84 are evenly welded perpendicular to the disc body surface. Each heat dissipation fin 84 is composed of a metal sheet 841 with a thickness of 3mm, a height of 50mm, and a length of 100mm. The heat dissipation fins 84 are spaced 20mm apart and are radially and evenly distributed on the outer circumference of the brake disc, greatly increasing the heat dissipation area.

[0034] Specifically, on the inner side of the electromagnetic brake clamp 91, a layer of magnetic friction pad 911 is bonded with a high-temperature resistant and high-strength adhesive. This magnetic friction pad is made of iron-based powder metallurgy material, with a thickness of 8mm. Its surface undergoes a special wear-resistant treatment, exhibiting excellent high-temperature resistance, and is covered with fine embossed textures to enhance friction. The mounting frame 9 is an L-shaped steel plate structure. One end of the mounting frame 9 is fixed to the machine body 2 with bolts 83, and the other end is fitted with the electromagnetic brake clamp 91. Furthermore, the mounting frame 9 has multiple adjustment holes 92 arranged in a straight line at equal intervals. Each adjustment hole 92 is equipped with an adjustment bolt 93 to adjust the height, allowing for flexible adjustment of the distance between the electromagnetic brake clamp 91 and the electromagnetic brake disc 8 according to actual installation and usage requirements. This ensures that during the operation of the wheel washing machine, the brake pads of the electromagnetic brake clamp 91 and the electromagnetic brake disc 8 always maintain a suitable gap, guaranteeing both braking sensitivity and reliability, while preventing excessive wear of the brake pads and brake disc due to insufficient clearance, thus extending the service life of the electromagnetic braking device.

[0036] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0037] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
