Description

Technical Field

[0001] The invention relates to the technical field of coal mine safety, and in particular to an anti-collision alarm device for an underground transport vehicle. Background Art

[0002] In the mining operation environment, underground transport vehicles, as key equipment, undertake the important task of transporting materials, equipment, personnel, etc. However, due to the long and irregular underground tunnels, limited working space, and the large number of vehicles, underground transportation operations face many safety hazards, especially in cases of poor visibility, large blind spots, and driver fatigue driving. Collisions between vehicles occur from time to time, seriously threatening the safe production of mines and the lives of operators. Traditional underground transport vehicle operations often rely on the driver's experience and attention, but in the complex underground mine environment, this method seems to be inadequate. Minor safety hazards or driver negligence may cause serious collision accidents, resulting in equipment damage, production interruptions, and even casualties.

[0003] Therefore, an anti-collision alarm device for underground transport vehicles is now developed, which can give early warning of collision accidents of underground transport vehicles, and can also perform auxiliary braking and buffering to avoid or reduce the occurrence of collision accidents. Summary of the invention

[0004] In order to overcome the shortcomings that the operation of traditional underground transport vehicles often relies on the driver's experience and attention, but in complex underground mine environments, serious collision accidents may occur, resulting in equipment damage, production interruption and even casualties, the present invention provides an underground transport vehicle anti-collision alarm device that can warn of collision accidents of underground transport vehicles and can perform auxiliary braking and buffering to avoid or reduce the occurrence of collision accidents.

[0005] The technical solution is: an anti-collision alarm device for an underground transport vehicle, including a track, a transport vehicle, a monitoring mechanism, a buffer mechanism, a braking mechanism and an alarm mechanism. A transport vehicle is placed on the track. The transport vehicle is provided with a monitoring mechanism capable of monitoring obstacles ahead, the monitoring mechanism is provided with a buffer mechanism capable of buffering collision impacts, the monitoring mechanism is also provided with a braking mechanism capable of auxiliary braking, and the monitoring mechanism is also provided with an alarm mechanism capable of issuing alarm reminders.

[0006] As an improvement of the above scheme, the monitoring mechanism includes a mounting plate, an anti-collision base station and a camera. The mounting plates are connected to the front and rear sides of the transport vehicle, the anti-collision base stations are connected to the sides of the mounting plates that are away from each other, the cameras are connected to the sides of the mounting plates that are away from each other, and the cameras are located on the left side of adjacent anti-collision base stations. The anti-collision base station and the camera on the mounting plate are started to monitor the road conditions in front of the transport vehicle. The anti-collision base station monitors the obstacles in front through wireless pulses, and the camera is started at the same time to assist in monitoring the picture in front of the train.

[0007] As an improvement of the above solution, a plurality of mounting holes are provided on the mounting plate.

[0008] As an improvement of the above scheme, it also includes a buffer mechanism, which includes a damper, a connecting plate, a sliding rod, a contact plate and an extrusion block. Multiple dampers are connected on the side of the mounting plates that are away from each other, and a connecting plate is connected between the dampers on the same side. The left and right parts of the connecting plate are slidably connected with upper and lower sliding rods. A contact plate is connected between the sides of adjacent upper sliding rods that are away from each other, and a contact plate is also connected between the sides of adjacent lower sliding rods that are away from each other. An extrusion block is connected between the sides of adjacent left sliding rods that are close to each other, and a contact plate is also connected between the sides of adjacent right sliding rods that are close to each other. An obstacle contacts the contact plate, and the contact plate is extruded to move toward the rear of the transport vehicle's travel route, so that the sliding rod slides on the connecting plate, so that the deformation of the damper buffers the impact of the obstacle.

[0009] As an improvement of the above solution, the extrusion block is an oblique structure.

[0010] As an improvement to the above solution, the contact plate is an arc-shaped structure.

[0011] As an improvement of the above scheme, a braking mechanism is also included, which includes a fixed plate, a sliding frame, a spring, a pressure plate and a fixing nail. The fixed ends of the lower dampers on the same side are connected with fixed plates, and the left and right sides of the fixed plate that are away from each other are slidably connected with sliding frames. The sliding frames are press-fitted with adjacent extrusion blocks, and multiple springs are connected between the sliding frames and the adjacent fixed plates. The lower side of the sliding frames is connected with a pressure plate, and the lower side of the pressure plate is connected with a fixing nail. The extrusion block moves backward, and the extrusion block is extruded and fitted with the sliding frame, so that the sliding frame slides downward on the fixed plate, and the spring is squeezed and contracted, so that the pressure plate moves downward.

[0012] As an improvement to the above solution, a friction plate is provided on the lower side of the pressure plate.

[0013] As an improvement to the above solution, the fixing nail is a conical structure.

[0014] As an improvement of the above scheme, an alarm mechanism is also included, which includes a fixing part and an alarm. The fixing parts are connected to the left and right sides of the mounting plate, and the alarm is connected to the fixing parts. When the anti-collision base station or the camera detects that there is an obstacle ahead of the driving route of the transport vehicle, the alarm on the fixing part is controlled to be started to sound an alarm.

[0015] The present invention has the following advantages: 1. The present invention assists the driver in monitoring the road conditions through a monitoring mechanism, buffers the collision through a buffer mechanism, performs auxiliary braking through a braking mechanism, and reminds the driver through an alarm mechanism, thereby achieving the effect of being able to provide early warning of collision accidents of underground transport vehicles, and at the same time being able to perform auxiliary braking and buffering to avoid or reduce the occurrence of collision accidents.

[0016] 2. The present invention monitors the road condition ahead of the transport vehicle by starting the anti-collision base station and the camera on the mounting plate. The anti-collision base station monitors the obstacles ahead through wireless pulses, and at the same time starts the camera to assist in monitoring the image ahead of the train. This achieves the effect of being able to judge the road condition ahead of the transport vehicle with the assistance of the anti-collision base station and the camera, thereby reducing the risk of safety accidents.

[0017] 3. The present invention squeezes the contact plate through the obstacle to move it to the rear of the transport vehicle's travel route, so that the sliding rod slides on the connecting plate, and the damper deforms to cushion the impact of the obstacle, thereby achieving the effect of being able to cushion the impact of the obstacle through the damper, preventing the transport vehicle from directly colliding with the obstacle and causing a safety accident.

[0018] 4. The present invention enables the extrusion block to move backward, so that the sliding frame slides downward on the fixed plate. The spring is squeezed and contracts, so that the pressure plate moves downward, and the fixed pins penetrate into the track surface to assist the transport vehicle in braking. This achieves the effect of assisting the transport vehicle in braking when the contact plate collides with an obstacle in front, slowing down the travel speed of the transport vehicle and reducing the risk of accidents.

[0019] 5. When the anti-collision base station or camera detects that there is an obstacle ahead of the transport vehicle's driving route, the present invention controls the alarm on the fixed part to start the alarm and remind the driver or relevant staff to take emergency measures. This achieves the effect of being able to give an alarm in time when an obstacle is detected ahead of the transport vehicle, making it convenient for the driver to take emergency measures.

DETAILED DESCRIPTION

[0028] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0029] An anti-collision alarm device for underground transport vehicles, such as Figure 1 and Figure 2 As shown, it includes a track 1, a transport vehicle 2, a monitoring mechanism 3, a buffer mechanism 4, a braking mechanism 5 and an alarm mechanism 6. The transport vehicle 2 is placed on the track 1. The transport vehicle 2 is provided with a monitoring mechanism 3 capable of monitoring obstacles ahead, the monitoring mechanism 3 is provided with a buffer mechanism 4 capable of buffering collision impact, the monitoring mechanism 3 is also provided with a braking mechanism 5 capable of auxiliary braking, and the monitoring mechanism 3 is also provided with an alarm mechanism 6 capable of alarming reminders.

[0030] like Figure 1 and Figure 3As shown, the monitoring mechanism 3 includes a mounting plate 31, an anti-collision base station 32 and a camera 33. The mounting plates 31 are connected to the front and rear sides of the transport vehicle 2. Six mounting holes are opened on the mounting plate 31 for easy connection with the transport vehicle 2. The anti-collision base station 32 is connected to the side of the mounting plates 31 away from each other. The cameras 33 are connected to the side of the mounting plates 31 away from each other. The cameras 33 are all located on the left side of the adjacent anti-collision base stations 32.

[0031] When using the present invention, firstly, the track 1 is set up on the transportation route of the underground transport vehicle 2, so that the transport vehicle 2 travels on the track 1 to transport minerals or workers in the coal mine. When the transport vehicle 2 travels on the track 1, the anti-collision base station 32 and the camera 33 on the mounting plate 31 are started to monitor the road conditions in front of the transport vehicle 2. The anti-collision base station 32 monitors the obstacles in front through wireless pulses, and at the same time, the camera 33 is started to assist in monitoring the picture in front of the train, and the monitoring results are transmitted to the driver of the lower transport vehicle 2 to assist the driver in judging the obstacles in front of the track 1, thereby playing a role in being able to assist in judging the road conditions in front of the transport vehicle 2 through the anti-collision base station 32 and the camera 33, thereby reducing the risk of safety accidents.

[0032] like Figure 1 and Figure 4 As shown, a buffer mechanism 4 is also included, which includes a damper 41, a connecting plate 42, a sliding rod 43, a contact plate 44 and an extrusion block 45. Six dampers 41 are connected to the side of the mounting plate 31 that is away from each other, and a connecting plate 42 is connected between the dampers 41 on the same side. The left and right parts of the connecting plate 42 are slidably connected with upper and lower sliding rods 43. A contact plate 44 is connected between the sides of adjacent upper sliding rods 43 that are away from each other, and a contact plate 44 is also connected between the sides of adjacent lower sliding rods 43 that are away from each other. An extrusion block 45 is connected between the sides of adjacent left sliding rods 43 that are close to each other. The extrusion block 45 is an oblique structure. A contact plate 44 is also connected between the sides of adjacent right sliding rods 43 that are close to each other. The contact plate 44 is an arc-shaped structure, which can disperse and buffer the impact force.

[0033] The buffer mechanism 4 of the device can buffer the impact of the collision. When the transport vehicle 2 does not react in time and collides with an obstacle in front, the obstacle contacts the contact plate 44, squeezing the contact plate 44 to move rearward on the travel route of the transport vehicle 2, so that the sliding rod 43 slides on the connecting plate 42, causing the damper 41 to deform to buffer the impact of the obstacle, thereby reducing the impact on the transport vehicle 2, thereby playing a role in being able to buffer the impact of the obstacle through the damper 41, and preventing the transport vehicle 2 from directly colliding with the obstacle and causing a safety accident.

[0034] like Figure 1 , Figure 5 and Figure 6 As shown, a braking mechanism 5 is also included, and the braking mechanism 5 includes a fixed plate 51, a sliding frame 52, a spring 53, a pressure plate 54 and a fixing nail 55. The fixed ends of the lower dampers 41 on the same side are connected with the fixed plates 51, and the left and right sides of the fixed plate 51 that are away from each other are slidably connected with the sliding frames 52. The sliding frames 52 are press-fitted with adjacent extrusion blocks 45, and two springs 53 are connected between the sliding frames 52 and the adjacent fixed plates 51. The lower side of the sliding frames 52 is connected with a pressure plate 54, and the lower side of the pressure plate 54 is provided with a friction plate to increase the friction with the track 1 for auxiliary braking. The lower side of the pressure plate 54 is connected with a fixing nail 55, and the fixing nail 55 is a conical structure, which is convenient for piercing into the ground for braking.

[0035] The braking mechanism 5 of the device can be used to perform emergency braking on the transport vehicle 2. When the transport vehicle 2 collides with an obstacle in front, the sliding rod 43 will be squeezed to slide backward on the connecting plate 42, so that the squeezing block 45 moves backward. The squeezing cooperation between the squeezing block 45 and the sliding frame 52 makes the sliding frame 52 slide downward on the fixed plate 51, and the spring 53 is squeezed and contracted, so that the pressure plate 54 moves downward, so that the fixing nail 55 penetrates into the ground of the track 1, so that the fixing nail 55 assists in braking the transport vehicle 2, thereby playing the role of assisting the transport vehicle 2 in braking when the contact plate 44 collides with the obstacle in front, slowing down the travel speed of the transport vehicle 2 and reducing the risk of accidents.

[0036] like Figure 1 and Figure 7 As shown, an alarm mechanism 6 is also included. The alarm mechanism 6 includes a fixing member 61 and an alarm 62. The fixing members 61 are connected to both sides of the mounting plate 31, and the fixing members 61 are connected to the alarm 62.

[0037] The alarm mechanism 6 of the present device can sound an alarm when an obstacle is detected. When the anti-collision base station 32 or the camera 33 detects that there is an obstacle ahead of the driving route of the transport vehicle 2, the alarm 62 on the starting fixing part 61 is controlled to sound an alarm, reminding the driver or relevant staff to take emergency measures. This ensures that when an obstacle is detected ahead of the transport vehicle 2, an alarm can be sounded in time, making it convenient for the driver to take emergency measures.

Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
