Description

Technical Field

[0001] This utility model relates to the technical field of mining engineering, specifically to a mine vehicle stopper to prevent runaway vehicles. Background Technology

[0002] In the mining process, mining cars are often used to transport ore, rubble and other materials. Using mining cars as a means of transportation helps to achieve efficient production. However, during the use of mining cars, some emergency situations often occur, which require emergency stopping. According to the regulations for the operation of mining vehicles, wheel stops must be added to the wheels when the vehicle stops to prevent the vehicle from sliding and causing safety accidents.

[0003] However, most currently used anti-runaway components need to be fixed to the track. These devices are complex, costly, and inconvenient to carry, making it difficult to effectively prevent mine cars from sliding forward or backward in a timely manner after an emergency stop, posing a serious safety hazard. Therefore, we offer a mine car stopper to solve these problems. Utility Model Content

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, this anti-runaway mining vehicle stop has the following advantages:

[0017] I. This anti-runaway mine car stopper, through the cooperation of the clamping plate, the car stopper, the sliding rod, the fixing plate and the spring, allows for quick installation of the car stopper when an emergency stop is required. This solves the problem that most existing anti-runaway components need to be fixed to the rail, and the anti-runaway devices are complex in structure, costly and inconvenient to carry.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a mine car stopper to prevent runaway vehicles, including a track body 1, with two fixing plates 12 arranged on the outer surface of the track body 1. The two fixing plates 12 are symmetrically distributed, and rubber blocks are provided on the outer surface of the fixing plates 12 to increase the friction with the track body 1 and prevent the fixing plates 12 from sliding.

[0028] A clamping plate 2 is slidably connected to the upper surface of the track body 1. A sliding rod 11 is slidably connected to the outer surface of the clamping plate 2. A fixing plate 12 is fixedly connected to one end of the sliding rod 11, and a handle 13 is fixedly connected to the other end of the sliding rod 11. Two people need to operate at the same time, pulling all four handles 13 simultaneously. One person pulls two handles 13 to move the two fixing plates 12 in a set away from each other, clamping the fixing plates 12 onto the outer surface of the track body 1. Releasing the handles 13 allows the two car stoppers 3 to be installed simultaneously. A spring 14 is sleeved on the outside of the sliding rod 11. One end of the spring 14 is connected to the outer surface of the fixing plate 12, and the other end of the spring 14 is connected to the outer surface of the clamping plate 2. Releasing the handles 13 causes the spring 14 to drive the two fixing plates 12 to clamp the track body 1.

[0029] A car stopper 3 is fixedly connected to the upper surface of the clamping plate 2. An ear plate 15 is fixedly connected to the outer surface of the clamping plate 2. A pin 16 is slidably connected to the outer surface of the ear plate 15. The pin 16 is inserted into the gravel road or dirt road below the track body 1 to fix the car stopper 3. The car stopper 3 is arc-shaped. An anti-slip strip 4 is fixedly connected to the outer surface of the car stopper 3. The anti-slip strip 4 is made of rubber. Rubber has high elasticity and soft texture. When the mine car wheel comes into contact, it has a certain buffer. The anti-slip strip 4 is evenly distributed in the lower half of the car stopper 3. A connecting plate 5 is fixedly connected to the outer surface of the clamping plate 2. An adjusting plate 6 is snapped onto the outside of the connecting plate 5.

[0030] A support rod 7 is fixedly connected to the outer surface of the adjusting plate 6. A threaded plate 8 is fixedly connected to one end of the support rod 7. A threaded rod 9 is threadedly connected to the inside of the threaded plate 8. The threaded rod 9 is a bidirectional screw with opposite thread directions at both ends. When the threaded rod 9 rotates, the two threaded plates 8 will move closer or further apart, thereby adjusting the distance between the two wheel stops 3. A groove 17 is provided on the outer surface of the connecting plate 5. A concave plate 18 is fixedly connected to the outer surface of the adjusting plate 6. The outer surface of the concave plate 18 is slidably connected to the inner wall of the groove 17. The concave plate 18 can fit perfectly into the inside of the groove 17, thereby installing the two wheel stops 3 together through the threaded rod 9 and the threaded plate 8 and other distance adjustment components, which facilitates the adjustment of the distance between the two wheel stops 3.

[0031] There are two track bodies 1. Each track body 1 has a wheel stopper 3 on its top. The two wheel stopsper 3 can be used separately or in combination. The concave plate 18 can be slid out from the inner wall of the groove 17 to separate the two wheel stopsper 3 for individual use, which can meet various needs. One end of the threaded rod 9 is fixedly connected to a handle 10. The handle 10 is cross-shaped, which makes it easy to rotate the threaded rod 9.

[0032] Working Principle: When using this device, there are two operating modes: Mode 1: Overall Use. After an emergency stop, pull all four handles 13 simultaneously to move the two fixing plates 12 in one set away from each other, clamping the fixing plates 12 onto the outer surface of the track body 1. Release the handles 13, and the spring 14 will cause the two fixing plates 12 to clamp the track body 1, allowing for quick installation of the two wheel stops 3. Then, insert the pin 16 into the gravel or dirt road below the track body 1 to double-fix the wheel stops 3. When it is necessary to change the distance between the two wheel stops 3, rotate the handle 10, and the threaded rod 9 will rotate, adjusting the distance between the two threaded plates 8, and thus the distance between the two wheel stops 3. This allows for the use of two track bodies 1 at different distances, improving the practicality of the device. Mode 2: Individual Use. When using a wheel stop 3 individually, slide the concave plate 18 out from the inner wall of the groove 17 to remove the support rod 7, threaded rod 9, and threaded plate 8 separately, separating the two wheel stops 3 for individual use. This achieves the effects of simple operation, convenient installation, and meeting diverse needs.
