One-way speed bump for slopes in coal mines

Abstract

The present invention relates to the technical field of underground transportation facilities in coal mines, and in particular to a speed bump, specifically a one-way speed bump used in slopes underground in coal mines. In order to solve the problem that the existing speed bump reduces the vehicle speed when going uphill, the present invention provides a new type of one-way speed bump used in slopes. It includes a speed bump body, a first guide rail, a second guide rail, a third guide rail, a block, a return spring and a damper. The present invention cleverly utilizes the linkage design of the mechanical structure and the effects of the damper and the return spring, so that when going uphill, the rubber-tyred trackless vehicle only needs to flatten the speed bump after the front wheels climb the slope, and the rear wheels can pass through the flattened speed bump without the need for the rear wheels to climb the slope again, thereby increasing the speed of the rubber-tyred trackless vehicle when going uphill, while also avoiding the bumps of the rear wheels when climbing the slope, and increasing the comfort of the driver when driving.

Description

Technical Field

[0001] The invention relates to the technical field of underground coal mine transportation facilities, in particular to a speed bump, specifically a one-way speed bump used in a slope underground in a coal mine. Background Art

[0002] In modern coal mines, many coal mines use trackless rubber-wheeled vehicles to transport personnel and materials. Compared with traditional transportation, the use of trackless rubber-wheeled vehicles for transportation improves transportation and production efficiency and reduces production accidents. Trackless rubber-wheeled vehicles will encounter sloping lanes during driving. For the safety of vehicles and pedestrians, speed bumps will be installed in sloping lanes to reduce the speed of trackless rubber-wheeled vehicles. When going downhill, speed bumps do play a role in reducing speed and improving safety. However, when going uphill, the vehicle speed is not very fast, and encountering speed bumps will further reduce the driving speed, which is easy to cause vehicle congestion, hindering the efficient coal mine transportation link and reducing production efficiency. Summary of the invention

[0003] In order to solve the problem that the existing speed reduction belt reduces the vehicle running speed when going uphill, the present invention provides a novel one-way speed reduction belt used in the slope of coal mine.

[0004] The present invention is implemented by adopting the following technical scheme: a one-way speed bump used in the slope of a coal mine, comprising a speed bump body, the speed bump body comprising an upslope plate, a downslope plate and a top plate, the upslope plate, the downslope plate and the top plate are all rectangular plates, the upper ends of the upslope plate and the downslope plate are respectively hinged to the two ends of the top plate, the two sides of the lower ends of the upslope plate and the downslope plate are respectively provided with a first guide rail parallel to the slope, the first guide rails are both placed on the slope ground and the upper surface of the first guide rails is flush with the slope surface, the first guide rails are both provided with a first slider sliding back and forth along the inclination direction of the slope, the two sides of the lower ends of the upslope plate and the downslope plate are respectively hinged to the first slider, the four corners of the lower surface of the top plate are hinged with a second guide rail for supporting the top plate, the bottom ends of the second guide rails are fixedly connected with a damper, and the damper and the second guide rail are located at The second guide rail is fixedly connected to the ground and is perpendicular to the slope. A return spring is placed in the ground on the downhill side of the second guide rail, and the placement direction of the return spring is perpendicular to the second guide rail. One end of the return spring contacts the second guide rail. The uphill side of the second guide rail is fixedly connected with a block placed on the ground. The second guide rail is provided with a second slider that slides back and forth along a direction perpendicular to the slope. A third guide rail placed along the slope direction is fixedly connected between every two second sliders that are directly opposite to each other in the direction of the slope. The third guide rail is provided with a third slider that slides back and forth along the direction of the slope. A trigger pedal is also provided on the outer side of the uphill plate, and the upper end of the trigger pedal is hinged to the uphill plate. The bottom ends of the front and rear sides of the trigger pedal are hinged with connecting rods and are hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the third slider.

[0005] During installation, first dig a first hole on the ground of the coal mine tunnel for placing a part of the second guide rail and the damper, the first hole is perpendicular to the slope and the hole width is greater than or equal to the width of the second guide rail and the length of the block in the slope direction, and a second hole perpendicular to the first hole is also opened on the downslope side of the first hole for placing a reset spring, and then place the first guide rail on both sides of the lower ends of the upper and lower slope plates, and fix it in the ground of the coal mine tunnel so that the upper surface of the first guide rail is flush with the slope surface. Working process: When going uphill, when the rubber-tyred trackless vehicle travels to contact with the trigger pedal, there is a thrust on the trigger pedal, so that the connecting rod drives the third slider to slide to the left on the third guide rail. When the third slider moves to the leftmost position of the third guide rail, the third slider pushes the second slider, and the second slider drives the second guide rail to move to the left. Due to the action of the return spring, the second guide rail drives the block to move to the left until the block is off the ground. At this time, when the front tire of the rubber-tyred trackless vehicle travels to the top plate, the rubber-tyred trackless vehicle applies a downward force to the top plate, so that the trigger pedal drives the connecting rod to slide to the right on the third guide rail until the trigger pedal The connecting rod is slowly flattened, and at the same time, the uphill and downhill plates drive the first slider to slide rightward and leftward on the first guide rail until the speed bump is slowly flattened. When the front wheel of the rubber-tyred trackless vehicle passes over the speed bump, the top plate will not be reset immediately due to the action of the damper. At this time, the rear wheel can quickly pass through the flattened speed bump, and then the damper is slowly reset, the reset spring is also reset, and the block is reset, so that the speed bump is slowly raised and restored to its original position; when going downhill, due to the action of the block, when the rubber-tyred trackless vehicle travels from the downhill plate to the top plate, the speed bump will not be flattened, so that the speed bump plays a certain deceleration role when going downhill.

[0006] The beneficial effects of the present invention are as follows: the present invention ingeniously utilizes the linkage design of the mechanical structure and the functions of the damper and the return spring, so that when the rubber-tyred trackless vehicle goes uphill, it only needs the front wheels to flatten the speed bump after climbing the slope, and the rear wheels can pass over the flattened speed bump without the need for the rear wheels to climb the slope again, thereby improving the driving speed of the rubber-tyred trackless vehicle when going uphill, and also avoiding the bumps of the rear wheels when climbing the slope, thereby increasing the comfort of the driver when driving.

One end of the return spring 11 contacts the second guide rail 6. The uphill side of the second guide rail 6 is fixedly connected with a block 14 placed on the ground. The second guide rail 6 is provided with a second slider 7 that slides back and forth in a direction perpendicular to the slope. A third guide rail 8 placed along the slope direction is fixedly connected between every two second sliders 7 that are directly opposite to each other in the slope direction. The third guide rail 8 is provided with a third slider 9 that slides back and forth in the slope direction. A trigger pedal 12 is also provided on the outer side of the uphill plate 1. The upper end of the trigger pedal 12 is hinged to the uphill plate 1, and the bottom ends of the front and rear sides of the trigger pedal 12 are hinged with a connecting rod 13 and are hinged to one end of the connecting rod 13, and the other end of the connecting rod 13 is hinged to the third slider 9.

[0011] During installation, first, a first hole is dug on the ground of the coal mine tunnel for placing a part of the second guide rail 6 and the damper 10. The first hole is perpendicular to the slope and the hole width is greater than or equal to the width of the second guide rail 6 and the length of the block 14 in the slope direction. A second hole perpendicular to the first hole is also opened on the downslope side of the first hole for placing the reset spring 11. Then, the first guide rail is placed on both sides of the lower ends of the upper and lower slope plates 1 and 2, and fixed in the ground of the coal mine tunnel so that the upper surface of the first guide rail 4 is flush with the slope surface. Working process: When going uphill, when the rubber-tyred trackless vehicle travels to contact with the trigger pedal 12, there is a thrust on the trigger pedal 12, so that the connecting rod 13 drives the third slider 9 to slide to the left on the third guide rail 8. When the third slider 9 moves to the leftmost position of the third guide rail 8, the third slider 9 pushes the second slider 7, and the second slider 7 drives the second guide rail 6 to move to the left. Due to the action of the return spring 11, the second guide rail 6 drives the block 14 to move to the left until the block 14 is off the ground. At this time, when the front tire of the rubber-tyred trackless vehicle travels to the top plate 3, the rubber-tyred trackless vehicle applies a downward force to the top plate 3, so that the trigger pedal 12 drives the connecting rod 13 to slide to the right on the third guide rail 8 until it contacts the trigger pedal 12. The starting pedal 12 and the connecting rod 13 are slowly flattened. At the same time, the uphill and downhill plates 1, 2 drive the first sliding block 5 to slide rightward and leftward on the first guide rail 4 until the speed bump is slowly flattened. When the front wheel of the rubber-tyred trackless vehicle passes over the speed bump, due to the effect of the damper 10, the top plate 3 will not be reset immediately. At this time, the rear wheel can quickly pass through the flattened speed bump. Then the damper 10 is slowly reset, the reset spring 11 is also reset, and the block 14 is reset, so that the speed bump is slowly raised and restored to its original position; when going downhill, due to the effect of the block 14, when the rubber-tyred trackless vehicle travels from the downhill plate 2 to the top plate 3, the speed bump will not be flattened, so that the speed bump plays a certain deceleration role when going downhill.

[0012] Brushes are fixedly connected to the front and rear sides of the guide groove of the first guide rail 4 to prevent large particles from entering the first guide rail 4 and affecting the use of the first guide rail 4, thereby playing a certain protective role for the first guide rail 4. The clamping block 14 is a wedge-shaped clamping block.
