Description

Technical Field

[0001] This utility model relates to the field of mine track transportation equipment technology, and in particular to a quick reset and correction device for mine car transportation after derailment. Background Technology

[0002] In underground rail transport systems such as mines and tunnels, derailment is a common and safety-affecting malfunction, especially for mine cars due to their heavy loads, frequent operation, and harsh working conditions. The causes of derailment are complex and include, but are not limited to: track subsidence or deformation caused by an unstable track foundation; excessive gaps or misalignment at track joints; insufficient turning radius at curves, causing wheel flanges to detach from the track due to centrifugal force; and vehicle instability, wheel wear, or sudden collisions.

[0003] Currently, the industry still widely uses traditional manual repositioning methods to handle derailed transport vehicles. These primarily include the jack lifting method and the chain hoisting method. The jack lifting method involves operators using hydraulic or mechanical jacks to slowly lift the frame or axle of the derailed vehicle until the wheels are above the track level. Then, multiple people work together to use pry bars and other tools to move the vehicle laterally, realigning the wheels with the track. This method not only requires carrying heavy jacks but also carries significant safety risks such as vehicle overturning and jack slippage during the lifting process, demanding extremely high levels of experience and teamwork from the operators. The chain hoisting method involves finding reliable anchor points in the tunnel roof, suspending a manual hoist, and then using chains to secure the vehicle body for lifting and lateral traction. This method is not only cumbersome and time-consuming to prepare, but also highly susceptible to secondary accidents such as chain breakage and anchor point detachment if the anchor points are unreliable or the operation is improper. Utility Model Content

[0004] Therefore, it is necessary to provide a quick reset and correction device for mine car derailment that addresses the above-mentioned technical problems. This device is simple to operate and takes little time.

[0005] This utility model provides a quick reset and correction device for mine car transportation after derailment, including a long plate-shaped main body, a herringbone-shaped adjustment groove track at the top, and an assembly groove through the bottom along the length direction that can be adapted to the mine car running track. The assembly slot is located in the middle of the bottom of the main body; The herringbone-shaped adjustment groove track includes a main groove track, a first branch groove track, and a second branch groove track. The main groove track is located in the middle of the top of the main body. The first branch groove track and the second branch groove track are symmetrically arranged on both sides of the main groove track. The first branch groove track and the second branch groove track are used to guide the derailed mine car to fall into the mine car running track after passing through the main groove track. Along the main groove track, from one end inside the main body towards the outside of the main body, the bottom of the main groove slopes downwards, and the inclined end is flush with the top of the assembly groove.

[0006] In one embodiment, the sections of the first branch groove track and the second branch groove track near the outer side of the main body are inclined downwards, with the inclined ends flush with the bottom of the main body.

[0007] In one embodiment, the length of the main groove track is greater than half the length of the main body, and the width of the main groove track is equal to the width of the assembly slot.

[0008] In one embodiment, multiple anti-slip studs are evenly distributed on the bottom of the main body, and the anti-slip studs are integrally connected to the main body.

[0009] The beneficial effects of this utility model are: (1) The herringbone-shaped adjustment groove track design is adopted. One set of devices can handle the situation where the mine car derails in either the inner or outer direction of the track, and it has strong versatility.

[0010] (2) The wheels of the derailed mine car can be naturally guided through the inclined inlet of the first branch groove track and the second branch groove track, and directly reset to the track along the main groove track. The whole process can be completed by simply pushing the vehicle. The operation is simple and does not require lifting the mine car, saving time and effort.

[0011] (3) The device can be stably mounted on the mine car track by the assembly slot at the bottom, preventing the device from shifting during the reset process and improving the stability and safety of operation. Attached Figure Description

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] It should be noted that in the description of this utility model, "upper," "lower," "top," "bottom," and orientation or positional relationship are based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the quick reset and correction device for mine car derailment in this embodiment includes a long plate-shaped main body 100, with a herringbone-shaped adjustment groove track 200 at the top and an assembly groove 300 that can be adapted to the mine car running track through the bottom along the length direction; the assembly groove 300 is located in the middle of the bottom of the main body 100.

[0017] The shape and width of the assembly slot 300 are matched with the track used for mine cars in the mine, so that the device can be stably mounted on the track through the assembly slot 300.

[0018] The herringbone-shaped adjustment groove track 200 includes a main groove track 210, a first branch groove track 220, and a second branch groove track 230. The main groove track 210 is located at the top center of the main body 100. The first branch groove track 220 and the second branch groove track 230 are symmetrically arranged on both sides of the main groove track 210. The first branch groove track 220 and the second branch groove track 230 are used to guide the derailed mine car to fall into the mine car running track after passing through the main groove track 210.

[0019] The ends of the first branch groove track 220 and the second branch groove track 230 away from the main groove track 210 are the entrances for the wheels of the track-adjusting mine cars.

[0020] Along the main groove track 210, located inside the main body 100, the bottom of the main groove slopes downwards towards the outside of the main body 100, with the inclined end flush with the top of the assembly groove 300. This design allows the wheel, guided from the branch groove track, to descend smoothly along the main groove track 210, eventually reaching the same height as the wheel on the track, achieving a stable reset.

[0021] In one embodiment, the sections of the first branch groove track 220 and the second branch groove track 230 near the outer side of the main body 100 are inclined downwards, with the inclined ends flush with the bottom of the main body 100, forming a gentle slope. This allows wheels that fall into different positions to easily roll into the groove track, avoiding the need to lift the mine car and reducing the workload of the operators.

[0022] In one embodiment, the length of the main groove track 210 is greater than half the length of the main body 100 to ensure sufficient length for smooth guidance; the width of the main groove track 210 is equal to the width of the mounting groove 300 to ensure continuity of wheel guidance.

[0023] In one embodiment, multiple anti-slip studs are evenly distributed on the bottom of the main body 100, and the anti-slip studs are integrally connected to the main body 100. When the device is placed on soft ground, the anti-slip studs can embed into the ground, effectively preventing the device from sliding under pressure.

[0024] The working principle of this utility model's rapid reset and correction device for mine car derailment is as follows: When the mine car derails to the outside of the right track, the device is placed in front of the wheel, so that the mounting groove 300 engages with the mine car's running track, and the entrance of the second branch groove track 230 is aligned with the derailed wheel. Pushing the mine car causes the wheel to roll along the second branch groove track 230. Guided and lowered by the main groove track 210, it finally smoothly enters and engages with the mine car's running track within the mounting groove 300, completing the reset. When the mine car derails to the inside of the track, the entrance of the first branch groove track 220 is aligned with the inside wheel, and the above operation is repeated.

[0025] 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 patent. 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.
