Description

Technical Field

[0001] This utility model relates to the field of safe operation technology of coal mine conveyor belts, and in particular to a belt pressing device at the tail of a conveyor belt. Background Technology

[0002] During belt operation, if the coal receiving plate at the tail end is too low, it can easily jam the belt buckle, leading to belt tearing, which greatly affects production and causes belt wear. Therefore, a physical clamping device is needed to prevent belt slippage or deviation during operation, thereby protecting the belt and belt buckle and reducing accidents such as belt breakage.

[0003] Therefore, to address the problem of the low coal receiving plate at the tail of the belt conveyor causing the belt buckle to easily get stuck, a device to prevent belt tearing can be designed. Utility Model Content

[0004] To overcome the problem that the coal receiving plate at the tail of the belt conveyor is too low and easily jams the belt buckle.

[0005] The technical solution of this utility model is as follows: a belt conveyor tail pressing device, including a shock-absorbing component, a left pressure roller and a right pressure roller; it also includes a left rotation adjustment component, a right rotation adjustment component and a lifting adjustment component; the shock-absorbing component includes a top plate and a bottom plate; a shock-absorbing pad and a steel plate are movably connected between the top plate and the bottom plate from top to bottom; a fixed seat is installed at the upper end of each of the two top plates; the lifting adjustment component is internally threaded to the fixed seat; the left rotation adjustment component and the right rotation adjustment component are respectively installed inside the two lifting adjustment components; the left rotation adjustment component includes a left rotation shaft; the left... An adjusting sleeve is fixedly connected to the right end of the rotating shaft; an annularly distributed limiting groove is provided on the inner side of the adjusting sleeve; a right rotating shaft is fixedly connected to the left end of the right rotating adjusting assembly; an adjusting block is fixedly connected to the left end of the right rotating shaft; an annularly distributed limiting protrusion is fixedly connected to the outer side of the adjusting block; a left pressure roller and a right pressure roller are respectively installed on the outer sides of the left and right rotating shafts; the lifting adjusting assembly includes an adjusting screw; the adjusting screw is threaded to the inner side of the upper end of the fixed seat; a screw base is fixedly connected to the lower end of the adjusting screw; a bearing is fixedly connected to the lower end of the screw base.

[0006] Preferably, based on the width of the belt conveyor, the left and right rotating shafts are pulled outwards simultaneously. The limiting protrusions on the outer side of the adjusting block move synchronously in the limiting groove on the inner side of the adjusting sleeve and stop at the desired position. The base plate is then fixed to the tail of the belt conveyor. The adjusting screw in the fixed seat is rotated, and the screw base converts the rotary motion into linear motion, driving the bearing downwards. The left and right pressure rollers move downwards synchronously, pressing down the tail belt and adjusting it to a suitable pressure. When the belt conveyor is working, it generates vibration, which is absorbed by the shock-absorbing pads and steel plates, thereby ensuring the stability of the left and right pressure rollers.

[0007] As a preferred option, multiple sets of shock-absorbing pads and steel plates are provided, and through holes are opened at the four corners of the shock-absorbing pads and steel plates; guide columns that are fixedly connected to the top plate and bottom plate are inserted into the through holes.

[0008] Preferably, the limiting groove and the limiting protrusion are engaged and connected; the surface of the limiting protrusion is provided with anti-slip texture.

[0009] Preferably, an adjusting handwheel is fixedly connected to the upper end of the adjusting screw; sliding blocks are fixedly connected to both ends of the bearing; and sliding grooves matching the sliding blocks are opened on the inner walls of both the front and rear sides of the fixed seat.

[0010] Preferably, a left rotating shaft and a right rotating shaft are installed in the two bearings respectively.

[0011] Preferably, the left and right pressure rollers are of the same specifications and are made of polyurethane.

[0012] The beneficial effects of this utility model are as follows: The overall structure is simple and sturdy. By pressing down the belt, the tail belt can transition better with the coal receiving plate, and the belt buckle will not get stuck. Therefore, the belt wear is reduced and the belt tearing is prevented. The height of the belt pressing device is adjustable, which makes it more compatible with the belt. The length is also adjustable, which allows it to press belts of different widths, which greatly improves the belt wear. Attached Figure Description

[0020] Please see Figures 3-4 In this embodiment, multiple sets of shock-absorbing pads 103 and steel plates 104 are provided. Through holes 105 are provided at the four corners of the shock-absorbing pads 103 and steel plates 104. Guide columns 106 that are fixedly connected to the top plate 101 and the bottom plate 102 are inserted into the through holes 105. The shock-absorbing pads are used to reduce vibration and improve the stability of the device. The limiting groove 203 and the limiting protrusion 303 are engaged. The surface of the limiting protrusion 303 is provided with anti-slip texture, which facilitates the adjustment of the length of the device and ensures the stability of the left pressure roller 4 and the right pressure roller 5 when rotating.

[0021] Please see Figure 1-Figure 2 and Figure 4 In this embodiment, an adjusting handwheel 702 is fixedly connected to the upper end of the adjusting screw 701; sliding blocks 9 are fixedly connected to both ends of the bearing 8; sliding grooves 10 matching the sliding blocks 9 are opened on the inner walls of both the front and rear sides of the fixed seat 6; as the sliding blocks 9 slide in the sliding grooves 10, the position of the bearing 8 is limited to prevent displacement; a left rotating shaft 201 and a right rotating shaft 301 are respectively installed in the two bearings 8; the left pressure roller 4 and the right pressure roller 5 are of the same specification, and the material of the left pressure roller 4 and the right pressure roller 5 is polyurethane, which is more durable and reduces the frequency of replacement.

[0022] During operation, the left rotating shaft 201 and the right rotating shaft 301 are pulled outward simultaneously according to the width of the belt conveyor.

The vibration is absorbed by the shock-absorbing pad 103 and the steel plate 104, thereby ensuring the stability of the left pressure roller 4 and the right pressure roller 5.

[0023] Through the above steps, by pressing down the belt, the tail belt transitions better with the coal receiving plate, preventing belt buckles from getting stuck. This reduces belt wear and prevents belt tearing. The height of the belt pressing device is adjustable, making it more compatible with belts. Its length is also adjustable, allowing it to press belts of different widths, thus solving the problem of the belt receiving plate at the tail of the belt conveyor being too low and easily getting the belt buckles stuck.
