Description

Technical Field

[0001] This patent application belongs to the technical field of belt conveyor equipment, and more specifically, relates to a linkage unloading vehicle braking device. Background Technology

[0002] Belt conveyors are commonly used material conveying facilities in industrial and mining enterprises, and unloading cars are important equipment for distributing materials from the belt to various equipment hoppers. They are widely used in industrial and mining enterprises due to their simple structure, low investment, and ease of operation. However, these unloading cars have certain drawbacks in the production process: firstly, the unloading car is heavy, has high inertia during movement, and results in an excessively long braking distance, making operation difficult; secondly, they lack safety devices, so when the drive wheel brake fails, the unloading car cannot brake, easily causing accidents or escalating existing ones.

The motor brake can brake the geared motor. The motor brake, driven wheel brake, and geared motor are all controlled by a remote control.

[0005] Furthermore, both the geared motor and the small sprocket are located on one side of the drive shaft, and the geared motor works in conjunction with the motor brake.

[0006] Furthermore, the limiter is a triangular steel plate.

[0007] Furthermore, the brake lever is a rod reinforced with tension bars.

[0008] Furthermore, the limit switch is located on the top of the side wall of the hopper.

[0009] Furthermore, the limit switch is an explosion-proof proximity switch.

[0010] The beneficial effects achieved by this utility model due to the adoption of the above technical solution are as follows: This device is easy to use, simple in structure and operation, requires little investment, has easily replaceable parts, and is highly practical. It can solve the problems of long braking distance of unloading vehicles and the inability of unloading vehicles to brake after the failure of the drive wheel brake, and has extremely high practical value.

[0014] The present invention will be further described in detail below with reference to the embodiments.

[0015] A linkage-type unloading vehicle braking device, such as Figure 1 , Figure 2 It includes an unloading trolley 12, a driven shaft 5 and a drive shaft 10 installed at the bottom of the unloading trolley 12, a drive wheel 4 installed on the driven shaft 5 and the drive shaft 10 respectively, a driven wheel brake 3 installed at both ends of the driven shaft 5, a chain 9 installed on one end of the drive shaft 10, a motor brake 11 connected to the chain 9, a large sprocket 8 installed on the other end of the drive shaft 10, a limit switch 2 installed on the track of the unloading trolley 12, a brake lever 13 installed at the head of the unloading trolley, a hopper 1 corresponding to the unloading trolley, a limit switch 14 installed on the side wall of the hopper 1 and corresponding to the brake lever 13, a driven wheel 15 installed on the driven shaft 5, and a track 16 for the movement of the unloading trolley 12.

[0016] In addition, it includes a geared motor 6 installed at the bottom of the unloading vehicle 12, a small sprocket 7 connected to the geared motor 6, and a large sprocket 8 connected to the small sprocket 7 via a chain 9. The motor brake 11 can brake the geared motor 6. The geared motor 6 and the small sprocket 7 are both located on one side of the drive shaft 10, and the geared motor 6 cooperates with the motor brake 11. The motor brake 11, the driven wheel brake 3, and the geared motor 6 are all controlled by a remote control.

[0017] In terms of design, the limit switch 2 is a triangular steel plate, and the brake rod 13 is a rod reinforced with tie rods. The limit switch 14 is located on the top of the side wall of the hopper 1, and the limit switch 14 is an explosion-proof proximity switch.

[0018] During the design and selection process, the materials and dimensions of the drive shaft 10 and driven shaft 5 are first determined based on the size and weight of the selected unloading vehicle 12. Then, a suitable brake (motor brake 11 / driven wheel brake 3) is selected based on the dimensions of the two shafts and the weight of the unloading vehicle 12. Next, a brake rod 13 of appropriate size and material is selected based on the limiting distance and weight of the unloading vehicle 12, and the brake rod 13 is reinforced. The brake (motor brake 11 / driven wheel brake 3) is then linked to the movement of the unloading vehicle 12. When the remote control button is pressed, the brake (motor brake 11 / driven wheel brake 3) does not work; when the button is released, the brake (motor brake 11 / driven wheel brake 3) performs a braking effect, reducing the braking distance of the unloading vehicle 12.

[0019] The method of use is as follows: The movement of the unloading car 12 is controlled by a remote control. The remote control is a commercially available standard product, and no specific requirements are specified; it can be selected according to the situation. When the move button is pressed on the remote control, the reduction motor 6 starts, driving the small sprocket 7 to transmit power to the large sprocket 8 through the chain 9. The large sprocket 8 drives the drive wheel 4 on the drive shaft 10 to move. When the desired position is reached, the move button is released on the remote control, and the motor brake 11 and the two driven wheel brakes 3 immediately start working. Through the friction of the brake blocks in the above-mentioned brakes, the inertia of the drive wheel 4 on the drive shaft 10 and the driven wheel 15 on the driven shaft 5 is counteracted, thereby achieving a fast and stable braking effect. When the unloading car 12 approaches the limit position, the braking distance of the unloading car 12 has been greatly reduced under the action of the above-mentioned brake. At this time, the limit switch 2 abuts against the driven wheel 4, which can bring the unloading car to a stop more quickly. If the remote control is not released in time due to an operational error, the brake lever 13 can push the limit switch 14 to make the motor brake 11 and the two driven wheel brakes 3 work, and stop the unloading car in time.
