[0018] Embodiment 1:

[0019] As Figures 1 - 3 shown, a protection device for enhancing the safety of a rotary dumper includes a rotary dumper support base 7. The top end face of the rotary dumper support base 7 is respectively provided with a lifting scissor jack 13, a left displacement scissor jack 9, a right displacement scissor jack 12, a lifting base 11, a rack 14, a left adjustment bolt 10, a right adjustment bolt 17, a right displacement scissor jack 12, a right positioning table 15 and rollers 5. The number of rollers 5 is set to two groups and is arranged in a mirror image with the center point of the top surface of the rotary dumper support base 7 as the axis. The lifting scissor jack 13, the left displacement scissor jack 9, the right displacement scissor jack 12, the lifting base 11, the rack 14, the left adjustment bolt 10, the right adjustment bolt 17, the right displacement scissor jack 12 and the right positioning table 15 are all arranged between the two groups of rollers 5; The rotary dumper is provided with a support base 7, and an end disc 1 and a rotary dumper drive device 4 are respectively arranged on the outside of the rotary dumper. The gear of the rotary dumper drive device 4 meshes with the ring gear of the rotary dumper end disc 1. A trailer beam platform 3 is arranged between the rotary dumper end discs 1, and a railway open wagon 2 can be parked on the trailer beam platform 3. A protection device 6 is arranged on the rotary dumper support base 7, and the rack of the protection device 6 can mesh with the ring gear of the rotary dumper end disc 1.

[0020] At the top and the outside of the tipping machine support base 7, there are respectively arranged a tipping machine end plate 1 and a tipping machine driving device 4. The top of the tipping machine driving device 4 is connected to the bottom end of the tipping machine end plate 1. Inside the tipping machine end plate 1, there are arranged an open-top railway wagon 2 and a trailer beam platform 3. The open-top railway wagon 2 and the trailer beam platform 3 are connected. Outside the tipping machine end plate 1, there is a gear ring. At the connection between the tipping machine support base 7 and the tipping machine end plate 1, there is a protection device 6.

[0021] A tipping machine is a large mechanical device used to unload open-top railway wagons, and is used to unload coal, ore and other bulk materials carried by various standard-gauge open-top railway wagons. In order to better unload materials, the tipping machine is usually equipped with components such as a motor reducer to drive it to perform forward tipping from 0° to 175° and reverse tipping from 175° to 0°. At the same time, in order to protect the tipping machine from the situation that the center of gravity deviates and it rotates out of control, a brake is installed on the tipping machine; at the same time, in order to prevent the center of gravity of the tipping machine from deviating and it rotates out of control, or when the tipping machine stops, the brake can prevent the tipping machine from tipping, playing a protective role.

[0022] However, if the braking force adjusted by the brake is insufficient or the friction plate fails, the tipping machine will rotate and cause a safety accident. Then, an additional insurance measure needs to be added to the tipping machine to ensure the safe use of the tipping machine and increase the reliability of the tipping machine.

[0023] When the brake of the tipping machine is being overhauled or due to other faults for overhaul, or when the tipping machine stops and needs to be strengthened in protection, when it stops at any angular position, in order to prevent the brake from failing, the scissor jack can be manually lifted and lowered to longitudinally roughly align the fixed rack close to the gear ring of the tipping machine. If there is a deviation in the meshing of the teeth on the left side of the fixed rack and the gear ring, the scissor jack for left displacement is manually operated to push the fixed rack to move right for adjustment. If there is a deviation in the meshing of the teeth on the right side of the fixed rack and the gear ring, the scissor jack for right displacement is manually operated to push the fixed rack to move left for adjustment. After the teeth are aligned, the scissor jack is manually lifted and lowered to further engage with the gear ring. If the tipping machine flips, it will drive the rack to move left and right in the horizontal direction. The left and right adjustment bolts are turned to be in close contact with the rack, so that the rack cannot move left and right. The fixed rack in the vertical position cannot move downward because it is supported by the scissor jack, thereby locking the tipping machine end plate and preventing the tipping machine from rotating.

[0024] When the dumper is repaired or needs to be started for flipping, the anti-runaway rotation device needs to be unlocked. Loosen the left and right adjustment bolts, move them away from the fixed rack, manually lower the scissor jack, and disengage the fixed rack from the gear ring. When the fixed rack approaches the chute position, if there is a deviation on the left side when entering the chute, manually operate the left displacement scissor jack to push the fixed rack for right displacement adjustment. If there is a deviation on the right side when the fixed rack enters the chute, manually operate the right displacement scissor jack to push the fixed rack for left displacement adjustment. When the fixed rack can completely enter the chute, manually lower the scissor jack continuously to return the fixed rack to the safe original position.

[0025] The rack of the protection device can be engaged with the gear ring of the dumper end plate for locking, and there are two directions of displacement in the process: vertical displacement and horizontal displacement. The vertical displacement is driven by the lifting scissor jack, and the horizontal displacement is driven by the left displacement scissor jack and the right displacement scissor jack; after the rack and the gear ring of the dumper end plate are locked, they are limited by the left adjustment bolt and the right adjustment bolt.

[0026] It can prevent the dumper from rotating out of control. When the brake fails, it can lock the dumper at any angle. The structure of this device is simple, and it can provide a device for preventing the dumper from rotating out of control with complete functions, safety and reliability, low manufacturing cost, and simple operation and maintenance.

[0027] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to this. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art.
