Description

Technical Field

[0001] This application relates to the technical field of forklift accessories, and in particular to a forklift brake auxiliary wheel. Background Technology

[0002] Forklifts are a type of machinery widely used in the industrial field, mainly for handling and stacking goods. Forklift brake auxiliary wheels are an important component of forklifts. Their main function is to provide auxiliary support when the forklift is braking, and to provide braking torque to the forklift through the steering shaft and connecting plate to enhance stability when lifting heavy loads.

[0003] During use, especially under harsh conditions such as working on muddy ground, existing forklift brake assist wheels are prone to mud adhesion. This mud adhesion not only affects the normal rotation of the rollers but also negatively impacts the braking effect of the entire braking system. When mud accumulates to a certain level, it increases the rolling resistance of the rollers, causing the brake assist wheel to respond more slowly and reducing the sensitivity of the braking system. When the driver needs to brake urgently, the brake assist wheel may not be able to function quickly and effectively due to the interference of mud, thus prolonging the braking distance and increasing the risk of accidents. In addition, mud may even completely cover parts of the rollers, rendering the brake assist wheel ineffective and, in severe cases, even causing brake failure, posing a serious safety hazard to the operator and the surrounding environment.

[0004] Therefore, in order to solve the above problems, this application provides a forklift brake auxiliary wheel.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0007] This application provides a forklift brake auxiliary wheel, including a wheel body and a roller shaft coaxially sleeved therewith. A braking part is installed on the roller shaft, and the braking part includes a brake and a connecting frame. The connecting frame is fixedly connected to the outer wall of the brake, and the connecting frame is mounted on the roller shaft through bearings. Cleaning parts are symmetrically distributed on both sides of the wheel body. A driving part located above the cleaning parts is installed on the braking part. A cleaning part and a water supply part are fixedly installed on the side of the driving part away from the braking part. The cleaning part includes a clamping plate, a cleaning brush plate, and a slider. The clamping plate is movably disposed at both ends of the wheel body and is movably penetrated by the roller shaft. A cleaning brush plate is fixedly installed on the inner side of the clamping plate, and the slider is fixedly installed on the top of the clamping plate.

[0008] Preferably, the drive unit includes a fixed block, a bidirectional lead screw, and a motor. The fixed block is fixedly installed on the brake and located directly above the cleaning unit. The motor is fixedly installed on the side wall of the fixed block, and the output shaft of the motor is fixedly installed with a bidirectional lead screw. The bidirectional lead screw is movably disposed inside the fixed block, and the sliders located on both sides of the wheel body are threaded through by the bidirectional lead screw.

[0018] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0019] Example 1: Refer to Figures 1-3 A forklift brake auxiliary wheel includes a wheel body 1 and a roller shaft 3 coaxially sleeved therewith. A braking part 2 is installed on the roller shaft 3. The braking part 2 includes a brake 201 and a connecting frame 202. The connecting frame 202 is fixedly connected to the outer wall of the brake 201. The connecting frame 202 is mounted on the roller shaft 3 through bearings. Cleaning parts 4 are symmetrically distributed on both sides of the wheel body 1. A driving part 5 is installed on the braking part 2 above the cleaning parts 4. A cleaning part 6 and a water supply part 7 are fixedly installed on the side of the driving part 5 away from the braking part 2. The cleaning part 4 includes a clamping plate 401, a cleaning brush plate 402 and a slider 403. The clamping plate 401 is movably disposed at both ends of the wheel body 1 and is movably penetrated by the roller shaft 3. The cleaning brush plate 402 is fixedly installed on the inner side of the clamping plate 401. The slider 403 is fixedly installed on the top of the clamping plate 401.

[0020] The drive unit 5 includes a fixed block 501, a bidirectional lead screw 502, and a motor 503. The fixed block 501 is fixedly installed on the brake 201 and located directly above the cleaning unit 4. The motor 503 is fixedly installed on the side wall of the fixed block 501, and the output shaft of the motor 503 is fixedly installed with the bidirectional lead screw 502. The bidirectional lead screw 502 is movably disposed inside the fixed block 501. The sliders 403, which are mirror-distributed on both sides of the wheel body 1, are threaded through by the bidirectional lead screw 502.

[0021] The cleaning unit 6 includes a water collection tank 601, a first nozzle 602 and a second nozzle 603. The water collection tank 601 is fixedly installed on the side wall of the fixing block 501, and the first nozzle 602 is fixedly installed at the bottom center of the water collection tank 601. The second nozzles 603 located on both sides of the first nozzle 602 are fixedly connected to the bottom sides of the water collection tank 601.

[0022] The water supply unit 7 includes a pump body 701 and a pipe 702, wherein the pipe 702 is connected to the inside of the water collection tank 601 through the pump body 701, and the pipe 702 is connected to the vehicle-mounted water supply tank.

[0023] The first nozzle 602 is directly facing the wheel body 1, and the second nozzle 603 is tilted and points towards the wheel body 1.

[0024] The implementation principle of a forklift brake auxiliary wheel in this application embodiment is as follows:

[0025] The output shaft of the control motor 503 drives the bidirectional lead screw 502 to rotate clockwise. The slider 403, which is threaded onto the bidirectional lead screw 502, will gradually move closer, further driving the clamping plate 401 and the cleaning brush plate 402 to move towards the wheel body 1, clamping the wheel body 1 located inside the cleaning brush plate 402. At the same time, the control pump 701 draws water from the vehicle water tank and adds water to the water collection tank 601 through the pipe 702. Then, the control first nozzle 602 and the second nozzle 603 spray the water in the water collection tank 601 onto the surface of the wheel body 1 so that the cleaning brush plate 402 attached to the wheel body 1 can scrub the wheel body 1, remove the mud on the wheel body 1, and avoid the mud on the wheel body 1 from having a negative impact on the braking effect of the braking system.

[0026] The output shaft of the control motor 503 drives the bidirectional lead screw 502 to rotate counterclockwise. The slider 403, which is threaded onto the bidirectional lead screw 502, will gradually move away, further driving the clamping plate 401 and the cleaning brush plate 402 to move away from the wheel body 1. This causes the cleaning brush plate 402 to no longer adhere to the surface of the wheel body 1. At this point, the cleaning part 4 returns to its initial state, ready for the next cleaning operation.
