Description

Technical Field

[0001] This utility model relates to the field of underground coal mining conveyor belt technology, and in particular to an anti-deviation device for underground coal mining conveyor belts. Background Technology

[0002] Underground mining refers to a mining method in coal mining that contrasts with open-pit mining. Compared to open-pit mining, underground mining technology is much more difficult. However, since most coal mines are buried underground, underground mining is necessary. In underground coal mining, conveyor belts are used to transport the coal, and these conveyor belts are limited by anti-deviation devices.

[0003] As shown in the reference case "Anti-deviation device for coal mine belt conveyor" announcement number "CN223238744U", by setting an output rod, specifically by a motor driving the output rod to rotate, the rotating roller five pulls the track to rotate, thus making the equipment run. The setting of the rotating roller five can ensure that the coal is smoothly transported at the track exit. Furthermore, the bottom rotating roller three supports the bottom of the track, which reduces the friction between the track and the cross plate after the track has been transported, thereby extending the service life of the track.

[0004] According to the above reference materials, in the above device, rotating the rotating ring in sequence causes the threaded rod to rotate, which in turn drives the sliding block to move up or down. As the sliding block moves upward, the support ear five on the left side rotates on the outer surface of the pin two, and then the support ear five is lifted, thereby increasing the angle between the rotating roller six and the horizontal plate. However, when transporting coal in the mine, the two adjusted rotating rollers six do not have an ideal limiting effect on both sides of the conveyor belt. The conveyor belt is prone to deviation when rotating, which affects the running stability of the conveyor belt and makes it inconvenient to limit and prevent deviation of the conveyor belt, thus reducing the effectiveness of the conveyor belt anti-deviation device. Utility Model Content

[0005] Therefore, it is necessary to provide a conveyor belt anti-deviation device for underground coal mining to address the problem of inconvenience in limiting and preventing conveyor belt deviation.

[0006] The device includes a mounting frame with several evenly arranged mounting plates on both sides of its top; an anti-deviation mechanism, which improves the anti-deviation effect of the conveyor belt, is located at the top of the mounting frame; the anti-deviation mechanism also includes a placement groove on one side of the mounting plate; a mounting block is slidably connected to the top of the inner wall of the mounting plate; two sets of rollers are rotatably connected to the bottom of the mounting block and the inner wall of the mounting plate, with two rollers in each set; the two sets of rollers are staggered with the other two sets of rollers; one side of each roller is located on the inner wall of the placement groove; and a limit component is provided at the top of the mounting frame.

[0007] In one embodiment, the anti-deviation mechanism further includes a threaded rod threaded to the top of the mounting plate, one end of which passes through the mounting plate and is rotatably connected to the top of the mounting block.

[0008] In one embodiment, a protective sleeve is fitted onto the outer wall of the threaded rod, one end of which is fixedly connected to the top of the mounting plate, and the other end of which is rotatably connected to the other end of the threaded rod.

[0009] In one embodiment, a number of evenly arranged rotating rods are rotatably connected to one side of the inner wall of the mounting plate.

[0010] In one embodiment, the rotating rod is disposed on one side of the roller.

[0011] In one embodiment, the limiting component includes a fixed frame fixedly connected to the top of the mounting bracket, the fixed frame being disposed at one end of the mounting plate, and a number of evenly arranged rollers being rotatably connected to the inner wall of the fixed frame, wherein two of the rollers are inclined.

[0012] In one embodiment, conveying rods are rotatably connected to both sides of the top of the fixed frame, and the two conveying rods are respectively disposed above two of the idler rollers.

[0013] In one embodiment, rollers are rotatably connected to both sides of the top of the mounting bracket, and the outer wall of the rollers is provided with several evenly arranged limiting grooves.

[0014] Beneficial effects 1. The above-mentioned anti-deviation device for underground coal mining conveyor belts has multiple mounting plates on both sides of the mounting frame that can limit the movement of the conveyor belt on both sides through placement grooves. Multiple sets of rollers are set on the inner wall of the placement grooves to guide the conveyor belt on both sides. The two sets of rollers at the upper and lower ends of the placement grooves are staggered. Rotating the threaded rod can drive the mounting block to move downwards. The mounting block drives two sets of rollers to move downwards and approach the other two sets of rollers, so that they can contact the upper and lower surfaces of the conveyor belt and limit the movement of the conveyor belt. Multiple rotating rods can limit and guide the movement of the conveyor belt on both sides, which can prevent the conveyor belt from deviating during operation and improve the stability of the conveyor belt for coal mine transportation. 2. Multiple idlers on the mounting frame can support the bottom of the conveyor belt. Two idlers are tilted to one side and cooperate with two conveyor rods to limit the conveyor belt and prevent it from deviating when rotating. Two rollers can limit the two ends of the conveyor belt to a certain extent through multiple limiting grooves on the roller surface, reducing the deviation of the conveyor belt and improving the anti-deviation effect of the conveyor belt.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figure 1 - Figure 5 This invention describes an anti-deviation device for underground coal mining conveyor belts.

[0020] In one embodiment, a conveyor belt anti-deviation device for underground coal mining includes a mounting frame 100, with several evenly arranged mounting plates 200 on both sides of the top of the mounting frame 100; an anti-deviation mechanism 300, which can improve the anti-deviation effect of the conveyor belt, is disposed at the top of the mounting frame 100; wherein, the anti-deviation mechanism 300 further includes a placement groove 310 opened on one side of the mounting plate 200, a mounting block 320 is slidably connected to the top of the inner wall of the mounting plate 200, and two sets of rollers 330 are rotatably connected to the bottom of the mounting block 320 and the inner wall of the mounting plate 200, each set of rollers 330 having two rollers, wherein the two sets of rollers 330 are interleaved with the other two sets of rollers 330, one side of the rollers 330 is disposed on the inner wall of the placement groove 310, and a limit component 370 is provided at the top of the mounting frame 100.

[0021] It should be noted that the underground coal mining conveyor belt of model "TD75" consists of: a belt, idler rollers 372, drums 374, drive unit, etc. The drive unit consists of an electric motor, a reducer, and a coupling, which provides power and regulates the speed and torque, and drives the conveyor belt through the roller 374. Idler roller 372 is designed to reduce running resistance and prevent misalignment. When using a conveyor belt to transport coal in a mine, the anti-deviation mechanism 300 guides the conveyor belt on both sides via the placement groove 310 on one side of the mounting plate 200. The roller 330 on one end of the mounting block 320 and roller 330 limits the upper and lower surfaces of the conveyor belt. It also works with the rotating rod 360 to limit the movement. The threaded rod 340 adjusts the distance between the roller 330 on the mounting block 320 and the roller 330 on the mounting plate 200. The limiting component 370 limits the conveyor belt via the idler roller 372 and two conveying rods 373. The two rollers 374 work with the limiting groove 375 to increase the resistance between them and the conveyor belt. The anti-deviation mechanism 300 and the limiting component 370 work together to prevent the conveyor belt from deviating, without affecting the normal use of the conveyor belt.

[0022] like Figure 2 and Figure 3 As shown, the anti-deviation mechanism 300 also includes a threaded rod 340 threaded to the top of the mounting plate 200. One end of the threaded rod 340 passes through the mounting plate 200 and is rotatably connected to the top of the mounting block 320. A protective sleeve 350 is sleeved on the outer wall of the threaded rod 340. One end of the protective sleeve 350 is fixedly connected to the top of the mounting plate 200, and the other end of the protective sleeve 350 is rotatably connected to the other end of the threaded rod 340. Several evenly arranged rotating rods 360 are rotatably connected to one side of the inner wall of the mounting plate 200. The rotating rods 360 are located on one side of the roller 330.

[0023] In this embodiment, when the two sides of the conveyor belt pass through the placement groove 310 on one side of the mounting plate 200, the threaded rod 340 is threadedly connected to the mounting plate 200 by rotating it. This causes the mounting block 320 to slide down along the inner wall of the mounting plate 200, which in turn causes two sets of rollers 330 to move closer to each other and come into contact with the upper and lower surfaces of the conveyor belt. This allows the conveyor belt to be conveyed in a limited manner. The two sides of the conveyor belt are also connected to multiple rotating rods 360 for further limiting. When the threaded rod 340 rotates, the protective sleeve 350 can extend and retract to protect the threaded rod 340, preventing the conveyor belt from deviating during operation and improving the effectiveness of the anti-deviation device.

[0024] like Figure 4 and Figure 5 As shown, the limiting component 370 includes a fixed frame 371 fixedly connected to the top of the mounting frame 100. The fixed frame 371 is disposed at one end of the mounting plate 200. Several evenly arranged rollers 372 are rotatably connected to the inner wall of the fixed frame 371, two of which are inclined. Conveying rods 373 are rotatably connected to both sides of the top of the fixed frame 371. The two conveying rods 373 are respectively disposed above two of the rollers 372. Rollers 374 are rotatably connected to both sides of the top of the mounting frame 100. Several evenly arranged limiting grooves 375 are opened on the outer wall of the rollers 374.

[0025] In this embodiment, the roller 374 cooperates with multiple limiting grooves 375 to stabilize the conveyor belt and drive it to rotate. When the conveyor belt passes the mounting plate 200, the bottom end of the conveyor belt contacts multiple idlers 372 on the fixing frame 371. Two of the idlers 372 are inclined to support and limit the conveyor belt. The two idlers 372 cooperate with two conveying rods 373 to limit the two sides of the conveyor belt, preventing the conveyor belt from deviating during rotation and improving the stability of the conveyor belt.

[0026] Working principle: Two rollers 374 are driven by an electric motor. The rollers 374 cooperate with multiple limiting grooves 375 on their surface to rotate the conveyor belt and transport the coal. The two sides of the conveyor belt pass through the placement grooves 310 on one side of the two mounting plates 200. Manually rotating the threaded rod 340, which is threaded to the mounting plate 200, can drive the two sets of rollers 330 at the bottom of the mounting block 320 to move downward, so that two sets of rollers 330 approach each other and contact the upper and lower surfaces of the conveyor belt respectively, which can limit the conveyor belt. The two sides of the conveyor belt are in contact with multiple rotating rods 360, which can prevent the conveyor belt from deviating. The conveyor belt then passes through idlers 372, two of which cooperate with the conveying rods 373 to guide the conveyor belt.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
