Description

Technical Field

[0001] This invention belongs to the field of braking technology, specifically referring to a wheel-stopping device for pure electric remote-controlled vehicles. Background Technology

[0002] Most current mining and industrial vehicles lack wheel-stopping mechanisms. When parking, wheel chocks are manually placed on the tracks at both ends of the vehicle. This poses safety risks to mining and industrial enterprises, including injuries from molten metal splashes, falling objects from heights, and harsh parking environments, as well as safety hazards to railway transport workers. Furthermore, manually placing wheel chocks is extremely inefficient, consumes a significant amount of time, and requires frequent handling, greatly reducing locomotive operating efficiency. The manual placement of wheel chocks at both ends of the vehicle during parking also results in considerable labor intensity. Summary of the Invention

[0003] To address the issue that most current industrial and mining vehicles lack wheel-stopping mechanisms and prevent vehicle slippage accidents, the current practice involves manually placing wheel chocks on the tracks at both ends of the vehicle when parking. However, due to safety risks such as liquid metal splashes, falling objects from heights, and harsh parking environments in industrial and mining enterprises, this invention proposes a fully electric remote-controlled vehicle wheel-stopping device.

[0004] The technical solution adopted by the present invention is as follows: The present invention provides a wheel-stopping device for a pure electric remote-controlled vehicle, including a bogie, a drive wheel on the bogie, and a wheel-stopping assembly on the bogie.

[0005] Furthermore, the wheel stop assembly includes a support mounting base, which is detachably mounted on the upper end of the bogie. The upper end of the support mounting base is provided with a support seat, and one end of the support seat is provided with an electric push rod. The output end of the electric push rod is hinged to a brake lever. One end of the bogie is provided with a lever fixing support. One end of the brake lever is rotatably sleeved on the shaft of the lever fixing support. One end of the brake lever is rotatably inner sleeved with a custom pin. A brake shoe support is sleeved on the custom pin. A brake shoe block is provided on one side of the brake shoe support, and a horizontal tie rod is provided on one side of the brake shoe support.

[0006] Furthermore, the output end of the electric actuator is provided with multiple sets of holes.

[0007] Furthermore, the brake lever is provided with a brake shoe elevation angle adjustment assembly on its side wall.

[0008] Furthermore, the brake shoe elevation angle adjustment assembly includes a fixing member, which is disposed on the side wall of the brake lever. The fixing member is provided with a rotating screw, and the fixing member and the rotating screw are threadedly connected. The lower end of the rotating screw is provided with a bearing, one end of the rotating screw is disposed on the inner ring of the bearing, the outer ring of the bearing is provided with a hinge, the lower end of the hinge is provided with a fixed shaft, and one side of the fixed shaft is disposed on the side wall of the brake shoe support.

[0009] Furthermore, the electric actuator is wirelessly connected to a dial-up remote control, and the electric actuator is powered by a pluggable and rechargeable lithium battery.

[0010] Furthermore, the brake lever is made of elastic steel plate.

[0011] The beneficial effects achieved by the present invention using the above structure are as follows:

[0012] (1) The electric push rod is used to brake and release the wheels.

[0013] (2) The electric push rod uses a pluggable and rechargeable lithium battery power supply, which makes it convenient to use electricity when the vehicle is moving and easy to replace the battery.

Detailed Implementation

[0019] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] like Figures 1-2 As shown, the bogie includes a bogie 1, on which a drive wheel 12 is mounted. A wheel stop assembly is also mounted on the bogie 1. The wheel stop assembly includes a support mounting base 3, which is detachably mounted on the upper end of the bogie 1. A support seat 2 is located at the upper end of the support mounting base 3. An electric push rod 4 is located at one end of the support seat 2. The output end of the electric push rod 4 has multiple sets of holes. A brake lever 5 is hinged to the output end of the electric push rod 4. The brake lever 5 is made of elastic steel plate. A brake shoe elevation angle adjustment assembly 7 is located on the side wall of the brake lever 5. The brake shoe elevation angle adjustment assembly 7 includes a fixing member 13, which is located on the side wall of the brake lever 5. A rotating screw 14 is located on the fixing member 13. The fixing member 13 and the rotating screw 14 are threadedly connected. A bearing 17 is located at the lower end of the rotating screw 14. One end of lever 14 is located on the inner ring of bearing 17. A hinge 16 is located on the outer ring of bearing 17. A fixed shaft 15 is located at the lower end of hinge 16. One side of fixed shaft 15 is located on the side wall of brake shoe support 9. One end of bogie 1 is provided with lever fixing support 6. One end of brake lever 5 is rotatably sleeved on the shaft of lever fixing support 6. A custom pin 8 is rotatably sleeved on one end of brake lever 5. A brake shoe support 9 is sleeved on the custom pin 8. A brake shoe block 11 is located on one side of brake shoe support 9. A horizontal pull rod 10 is located on one side of brake shoe support 9. Electric push rod 4 uses a pluggable rechargeable lithium battery power supply. Electric push rod 4 has a self-locking function and can provide braking force for long-term parking. Electric push rod 4 is wirelessly connected to a dial remote control. The dial remote control is provided with a status indicator light.

[0021] In practical use, during the parking brake operation, the electric push rod 4 and the dial-up remote control are wirelessly connected, allowing multiple mining vehicles to be controlled with a single remote control. This is convenient for operators to carry. When a positive voltage is applied to the electric push rod 4, its output end extends, causing the upper end of the brake lever 5 to move outwards and the lower end to move inwards, thus causing the brake shoe support 9 to move inwards. When the brake shoe 11 contacts the drive wheel 12, the resistance gradually increases. When the thrust of the electric push rod 4 reaches the set value, the pressure of the brake shoe 11 reaches the design value. At this point, the current of the electric push rod 4 reaches the predetermined value, the circuit is de-energized, and the electric push rod 4 stops moving. The internal self-locking mechanism prevents the electric push rod 4 from retracting, and the parking brake remains engaged. When the parking brake is engaged, the electric push rod... When a reverse voltage is applied, the output end of the electric push rod 4 retracts. When the electric push rod 4 retracts to its limit, the limit switch sends a power-off signal to the circuit, the electric push rod 4 stops moving, and the parking brake is released. When the electric push rod 4 fails, the connection between the electric push rod 4 and the brake lever 5 can be manually released, at which point the parking brake is released. When the remote control system malfunctions and cannot be operated, the braking force can be manually released to release the parking state, allowing the vehicle to run normally and eliminating the impact of the malfunction on production operations. Rotating the lead screw 14 causes the bearing 17 and hinge 16 to move diagonally downwards. The movement of the hinge 16 causes the fixed shaft 15 to move, thereby causing the brake shoe support 9 to move, adjusting the contact surface between the brake shoe block 11 and the wheel. The above is the overall workflow of this invention. This step can be repeated for the next use.

[0022] As can be seen from the above embodiments, the beneficial effects of the present invention are as follows:

[0023] The electric push rod is used to brake and release the wheels. The electric push rod is powered by a plug-in rechargeable lithium battery, making it convenient to use electricity while the vehicle is moving and easy to swap batteries. When the electric push rod fails, the connection between the electric push rod and the brake lever can be manually released, at which point the parking brake is released.

[0024] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
