Description

A manual reset device for preventing runaway vehicles in mining applications Technical Field

[0001] This utility model relates to the technical field of vehicle blocking devices, and in particular to a manual reset vehicle blocking device for preventing runaway vehicles in mining applications. Background Technology

[0002] A car stopper, also known as a parking device, is an important facility in the coal mine transportation system. It is a type of runaway prevention device, and its purpose is to quickly stop the mine car in an emergency to prevent it from sliding out of control.

[0003] A search revealed that the Chinese patent "A Track-Stopping Device for Mining" (authorization announcement number CN215663448U) includes a pair of axisymmetric track-stopping units. Each track-stopping unit comprises a track-stopping body and a fixed base. The track-stopping body is equipped with a track-stopping block, a track clamping groove, and a connecting block. The fixed base includes a track clamping plate slot, an outer connecting piece, and a connecting plate connecting the track clamping plate slot and the bottom of the connecting piece. The track clamping plate slot has opposing threaded holes on both sides, with fastening bolts passing through the opposing threaded holes. The connecting block of the track-stopping body and the connecting piece of the fixed base are connected by a pin, allowing the track-stopping body to rotate 180 degrees outward via the pin. This provides a track-stopping device for mining that offers good safety, effective braking, and eliminates the need for movement or handling. However, in practical use, this method has the following drawbacks: relying solely on the track-stopping block for rigid contact results in a generally poor stopping effect, and the track-stopping block is prone to deformation and damage during the stopping process, leading to cumbersome replacement procedures. Summary of the Invention

[0004] Therefore, it is necessary to provide a manual reset anti-runaway vehicle device for mining, which addresses the problems of mediocre anti-runaway effect and easy deformation and damage of the anti-runaway blocks.

[0005] A manual reset device for preventing runaway vehicles in mining applications includes a base plate and two runaway blocks mounted on its outer side, arranged symmetrically. It also includes a docking mechanism located on the outer side of the runaway blocks and used for quickly disassembling and replacing them. The docking mechanism includes a set of docking strips and a docking frame. The docking strips have a T-shaped cross-section, and the docking frame has a set of grooves for docking with the docking strips. The docking strips are fixedly installed on the outer side of the runaway blocks, and reinforcing bolts are provided between the docking strips and the docking frame.

[0006] In one embodiment, a vehicle-stopping pad is provided on one side of the vehicle-stopping block, a buffer is provided on the outer side of the vehicle-stopping pad, and a vehicle-stopping strip is provided at the bottom of the vehicle-stopping pad.

[0007] In one embodiment, the substrate is provided with two hinge seats, the docking frame is installed inside the hinge seats, and the substrate is provided with a mine car track.

[0008] In one embodiment, a connecting frame is provided between the vehicle blocking pad and the base plate, the connecting frame is slidably connected to the base plate, and the vehicle blocking strip is bolted to the connecting frame and contacts the outer side of the base plate.

[0009] In one embodiment, the buffer includes a support tube, a support rod, and a damping disk. The damping disk has a set of damping holes inside. The support tube is installed on the outside of the hinge seat. One end of the support rod passes through the support tube and is connected to the damping disk. The damping disk is slidably connected to the inside of the support tube.

[0010] In one embodiment, two T-shaped pads are provided between the docking frame and the vehicle blocking block.

[0011] In one embodiment, both sides of the hinge seat are provided with support plates mounted on the base plate, the support plates being used to support the vehicle stop block. Beneficial Effects

[0012] 1. By setting up docking bars and docking brackets, along with T-shaped pads and reinforcing bolts, the assembly and disassembly of individual vehicle blocking blocks can be completed quickly, making subsequent replacement convenient;

[0013] 2. By setting damping pads, damping strips and damping discs, multi-stage buffering can be performed on the vehicle blocking blocks before they are used for vehicle blocking operations, thereby improving the vehicle blocking effect and reducing the deformation and damage of the vehicle blocking blocks.

[0027] The following describes the manual reset device for preventing runaway vehicles in mining applications, in conjunction with Figures 1-5.

[0028] In one embodiment, a mine runaway prevention manual reset vehicle blocking device includes a base plate and two vehicle blocking blocks 100 mounted on its outer side. The number of vehicle blocking blocks 100 is two and they are arranged symmetrically. It also includes a docking mechanism 200, which is disposed on the outer side of the vehicle blocking blocks 100 and is used to quickly complete the disassembly and replacement of the vehicle blocking blocks 100. The docking mechanism 200 includes a set of docking strips 210 and a docking frame 220. The cross-section of the docking strips 210 is T-shaped. The docking frame 220 has a set of sliding grooves for docking with the docking strips 210. The docking strips 210 are fixedly installed on the outer side of the vehicle blocking blocks 100. A reinforcing bolt is provided between the docking strips 210 and the docking frame 220.

[0029] As shown in Figures 1, 3, 4 and 5, a vehicle blocking pad 110 is provided on one side of the vehicle blocking block 100, a buffer 300 is provided on the outer side of the vehicle blocking pad 110, and a vehicle blocking strip 111 is provided at the bottom of the vehicle blocking pad 110.

[0030] In this embodiment, during the vehicle blocking operation, the vehicle blocking pad 110 is pre-connected with the mine car wheel, and then the vehicle blocking pad 110 and the mine car slide synchronously. During the sliding process, the friction generated by the vehicle blocking strip 111 and the contact point achieves the vehicle blocking effect. After sliding a certain distance, the buffer 300 is compressed, and then auxiliary buffering is performed to further improve the vehicle blocking effect. After the buffering operation is completed, the vehicle blocking pad 110 will come into contact with the vehicle blocking block 100 to perform contact blocking treatment, thus completing the vehicle blocking of the mine car. If the vehicle blocking pad 110 or the vehicle blocking block 100 is deformed and damaged beyond repair after the vehicle blocking operation is completed, the user can remove the bolts at the corresponding points and then directly replace the vehicle blocking pad 110, or pull out the connecting strip 210 on the vehicle blocking block 100 along the connecting frame 220 for replacement.

[0031] It should be noted that if the vehicle blocking pad 110 and the vehicle blocking block 100 are slightly deformed, the user can make simple repairs. If it does not affect the vehicle blocking operation, it can be put into subsequent use directly.

[0032] The shape, thickness, and height of the car-stopping block 100 in this application can be pre-selected according to the usage environment and the specifications of the mine car track.

[0033] As shown in Figures 1 and 2, two hinge seats are provided on the base plate, and the docking frame 220 is installed inside the hinge seats. A mine car track is provided on the base plate.

[0034] The docking frame 220 is supported by a hinged seat;

[0035] It should be noted that the entire structure of this application is set on the base plate, and the corresponding setting position can be adjusted according to the gap of the mine car track before installation.

[0036] As shown in Figures 1 and 5, a connecting frame 112 is provided between the vehicle blocking pad 110 and the base plate. The connecting frame 112 is slidably connected to the base plate, and the vehicle blocking strip 111 is connected to the connecting frame 112 by bolts and contacts the outer side of the base plate.

[0037] The vehicle blocking strip 111 is used to improve the vehicle blocking effect of the vehicle blocking pad 110, and it adopts a detachable design, so users can replace the vehicle blocking strip 111 regularly according to the wear condition.

[0038] As shown in Figures 1, 3 and 4, the buffer 300 includes a support tube 310, a support rod 320 and a damping disk 330. The damping disk 330 has a set of damping holes inside. The support tube 310 is installed on the outside of the hinge seat. One end of the support rod 320 passes through the support tube 310 and is connected to the damping disk 330. The damping disk 330 is slidably connected to the inside of the support tube 310.

[0039] During the vehicle blocking process, the connecting frame 112 will move and come into contact with the support rod 320. Then the damping disc 330 will move. During its movement, the buffer oil in the support tube 310 will be discharged along the damping hole. The flow resistance of the buffer oil will be used for damping treatment to achieve the buffer blocking effect.

[0040] As shown in Figure 2, two T-shaped pads 221 are provided between the docking frame 220 and the vehicle blocking block 100.

[0041] By inserting a T-shaped pad 221 into the gap between the docking frame 220 and the vehicle blocking block 100, the structural strength of both is improved during the vehicle blocking process, providing auxiliary support and reducing the phenomenon that the corresponding side of the vehicle blocking block 100 shifts along the gap after being impacted.

[0042] As shown in Figure 1, both sides of the hinge seat are provided with support plates that are mounted on the base plate. The support plates are used to support the vehicle blocking block 100.

[0043] During the use and waiting period of the vehicle blocking block 100, it is supported by the corresponding support plate.

[0044] Working principle: When stopping a car, the user can push the car-stopping pad 110 onto the track, then flip the car-stopping block 100 to the outside of the track. The car-stopping pad 110 then makes pre-contact with the mine car wheel for buffering. Next, the buffer component 300 supports the connecting frame 112 for auxiliary buffering. Finally, the car-stopping block 100 makes hard contact with the car-stopping pad 110 to complete the final car-stopping process. After stopping the car, the user can manually reset the car-stopping pad 110, the buffer component 300, and the car-stopping block 100 in sequence for the next use.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
