Description

Technical Field

[0001] The utility model relates to the technical field of coal mine safety equipment, in particular to an integrated vehicle blocking device for inclined shaft mine vehicle transportation. Background Art

[0002] In the process of coal mining, inclined mine car transportation plays a vital role. It is responsible for transporting coal, gangue, materials and personnel to the designated location safely and efficiently. However, due to its special terrain conditions and complex operating environment, inclined transportation often faces many safety hazards, especially mine car loss of control or landslide accidents. Such accidents will not only lead to production interruptions, but may also cause serious casualties and property losses, posing a serious threat to the safe production and economic benefits of coal mines. When the mine car landslides or loses control, a car-blocking device is usually set to slow down the running speed of the mine car, so that the mine car stops and avoids accidents.

[0003] The existing inclined shaft mine car blocking device usually sets a buffer and a blocking plate in front of the mine car to block the mine car, increase the friction between the mine car and the track, and slow down the mine car. However, when blocking the mine car, most of them adopt a single braking method, which is difficult to adapt to the braking needs under different working conditions, especially in the complex and changeable inclined shaft transportation environment. It is impossible to fully absorb the kinetic energy of the mine car when it slides, and its braking effect is often difficult to guarantee.

[0004] Therefore, an integrated vehicle arresting device for inclined mine car transportation has been developed, which can effectively absorb the kinetic energy of the inclined mine car when it loses control due to landslide through multi-stage braking and deceleration, thereby ensuring the safe braking of the mine car. Utility Model Content

[0005] In order to overcome the shortcomings of existing inclined mine car arresting devices, most of which adopt a single braking method and are difficult to adapt to the braking requirements under different working conditions, especially in complex and changeable inclined shaft transportation environments, and are unable to fully absorb the kinetic energy of the mine car when it landslides, the utility model provides an integrated car arresting device for inclined mine car transportation that can effectively absorb the kinetic energy of the inclined mine car when it landslides out of control through a multi-stage braking and deceleration method to ensure the safe braking of the mine car.

[0006] The technical solution of the utility model is: an integrated car-blocking device for inclined shaft mine car transportation, including a base, a shock-absorbing shaft, a first spring, a second spring, a track frame, a fixed frame, a wheel-blocking plate, a third spring and a friction plate. The base has two front and rear bases, the left parts of the bases are slidably connected with the shock-absorbing shafts, the shock-absorbing shafts are connected to the first springs between the adjacent bases, the left parts of the shock-absorbing shafts are slidably connected with the track frame, the shock-absorbing shafts are connected to the second springs between the track frames, the upper left side of the track frame is connected with the fixed frame, the right side of the fixed frame is slidably connected with the wheel-blocking plate, the third spring is connected between the wheel-blocking plate and the fixed frame, and the friction plate is connected to the left side of the lower part of the wheel-blocking plate.

[0007] As a further preferred solution, a friction plate is provided on the baffle plate.

[0008] As a further preferred solution, it also includes a bidirectional screw and a limiting plate. The left side of the upper part of the wheel blocking plate is rotatably connected to the bidirectional screw. The front and rear parts of the bidirectional screw are both threadedly connected to the limiting plates. The limiting plates are slidably connected to the friction plates.

[0009] As a further preferred solution, a knob is provided on the bidirectional screw rod.

[0010] As a further preferred solution, it also includes fixing nails and sleeper blocks, and the ends of the base that are away from each other are connected to the left and right fixing nails, and the fixing nails are connected to the sleeper blocks.

[0011] As a further preferred solution, the sleeper blocks are all U-shaped.

[0012] The utility model has the following advantages: the utility model performs friction braking between the wheel block plate and the wheel of the mine car, and at the same time rubs the track through the friction plate to slow down the mine car, and further buffers and slows down the mine car under the action of the first spring, the second spring and the third spring, thereby achieving the effect of being able to effectively absorb the kinetic energy of the inclined shaft mine car when it lands out of control through multi-stage braking and deceleration, thereby ensuring the safe braking of the mine car.

[0020] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0021] An integrated vehicle blocking device for inclined mine vehicle transportation, such as Figure 1-Figure 6 As shown, it includes a base 1, a shock-absorbing shaft 2, a first spring 3, a second spring 4, a track frame 5, a fixing frame 6, a wheel blocking plate 7, a third spring 8, a friction plate 9, a bidirectional screw rod 10, a limiting plate 11, a fixing nail 12 and a sleeper block 13. The base 1 has two front and rear parts, the left part of the base 1 is slidably connected with the shock-absorbing shaft 2, the shock-absorbing shaft 2 is connected to the adjacent base 1 with the first spring 3, the left part of the shock-absorbing shaft 2 is slidably connected with the track frame 5, the shock-absorbing shaft 2 is connected to the track frame 5 with the second spring 4, the upper side of the left part of the track frame 5 is connected with the fixing frame 6, the right part of the fixing frame 6 is slidably connected with the wheel blocking plate 7, the A third spring 8 is connected between the wheel plate 7 and the fixed frame 6, a friction plate 9 is connected to the left side of the lower part of the wheel blocking plate 7, and a friction plate is provided on the wheel blocking plate 7 to increase the friction between the wheel blocking plate 7 and the wheel of the mine car. A two-way screw rod 10 is rotatably connected to the left side of the upper part of the wheel blocking plate 7, and the front and rear parts of the two-way screw rod 10 are both threadedly connected to limit plates 11, and the limit plates 11 are both slidably connected to the friction plate 9. A knob is provided on the two-way screw rod 10 for easy rotation, and two left and right fixing nails 12 are connected to the ends of the base 1 away from each other, and sleeper blocks 13 are connected to the fixing nails 12. The sleeper blocks 13 are all U-shaped for easy clamping and fixing of the sleepers.

[0022] When using the utility model, first place the base 1 on the mine car transport track so that the front and rear bases 1 are stuck on the edge of the transport track and the base 1 is fixed by the fixing nails 12. When there are sleepers on the transport track, the sleeper block 13 can be adjusted to engage with the sleepers of the track, thereby strengthening the fixing effect of the base 1. When the mine car moves to the position of the base 1, the wheels of the mine car contact the wheel blocking plate 7, and the wheels are decelerated and braked by the friction between the wheel blocking plate 7 and the wheels. At the same time, under the impact of the mine car, the wheel blocking plate 7 slides on the fixed frame 6, and the third spring 8 is squeezed and contracted to buffer the impact. When the wheel blocking plate 7 slides, the friction plate 9 is driven to slide on the track. The friction between the friction plate 9 and the track further decelerates and brakes the mine car. Under the impact of the mine car, the track frame 5 moves to the left at the same time. The sliding frame slides to the left, and the shock absorber shaft 2 is driven to slide to the left under the action of the second spring 4, so that the first spring 3 and the second spring 4 are squeezed and contracted, the impact of the mine car is buffered, and the mine car is decelerated and braked. When the wheel block plate 7 and the friction plate 9 perform friction braking on the wheels of the mine car, the limiting plates 11 are located on both sides of the wheels, and the wheels are limited while the wheels are frictionally decelerated to prevent the wheels from derailing. By rotating the bidirectional screw rod 10, the limiting plate 11 slides on the wheel block plate 7 under the action of the thread, and the distance between the two limiting plates is adjusted to adapt to the size of the wheel, which can adapt to the role of blocking the mine cars with wheels of different sizes, so that the kinetic energy of the inclined mine car when it loses control of the landslide can be effectively absorbed through multi-stage braking and deceleration, ensuring the safe braking of the mine car.
