Description

Technical Field

[0001] The utility model relates to the field of tear prevention, and in particular to an anti-tear protection device for a conveyor. Background Art

[0002] A conveyor is an industrial equipment used in mines. It uses mechanical power to automatically transfer materials, greatly improving production efficiency and logistics management. This equipment usually contains one or more conveying media, such as chains, belts, rollers or other similar mechanisms, which can move materials from one designated location to another.

[0003] Conveyors can not only improve the efficiency of material transportation and reduce labor costs, but also maintain stable operation in complex environments and ensure production safety. With the continuous improvement of industrial automation levels, the intelligence and networking of conveyors will also become a future development trend, further promoting the improvement of industrial production efficiency and the reduction of costs.

[0004] At present, in the production process of mines, most conveyors use rubber belts to transport materials. However, since mine conveyors often need to carry out long-distance and high-intensity work, they will cause great pressure and wear on the belts; during long-term operation, the belts are prone to tearing.

[0005] The tearing of the belt will not only affect the normal operation of the conveyor, resulting in a decrease in transportation efficiency, but also because the torn belt is not discovered in time and the conveyor is not stopped, the torn part may further expand, causing the entire belt to break, and may also cause damage to the conveyor, increasing production costs and the probability of safety hazards.

[0006] The spacing between the conveyor shafts on existing conveyors is usually fixed. Therefore, the pressure received by the conveyor belt itself cannot be adjusted by changing the spacing between the conveyor shafts, resulting in the conveyor belt being torn. When the belt is torn, the conveyor cannot be shut down in time to reduce the impact of the tearing by only manually inspecting and observing the conveyor.

[0007] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0026] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] According to an embodiment of the utility model, a conveyor anti-tear protection device is provided.

[0028] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 4 As shown, the conveyor anti-tear protection device according to the embodiment of the utility model includes a base plate 1, an adjusting component 2 is symmetrically arranged on the top of the base plate 1, a bracket 3 matched with the base plate 1 is arranged at the middle position of two groups of adjusting components 2, a conveying shaft 4 is arranged on the top of the bracket 3, a conveying belt 5 is arranged on the top of the two groups of conveying shafts 4, and a supporting component 6 matched with the two groups of brackets 3 is symmetrically arranged on the bottom end of the conveyor belt 5, and a detection part 7 matched with the bracket 3 is arranged on one side of the two groups of supporting components 6.

[0029] With the help of the above technical scheme, the utility model can detect the squeezing of the conveyor belt 5 on the support plate 601 in real time during the mining process under the action of the adjusting component 2, the supporting component 6 and the detecting component 7, and when the squeezing reaches a certain degree, adjust the spacing between the conveyor shafts 4, and at the same time, under the support of the supporting component 6, timely increase the supporting force of the conveyor belt 5, thereby avoiding the situation that the conveyor belt 5 is torn, and achieves the effect of preventing the conveyor belt 5 of the conveyor from being torn; under the action of the adjusting component 2, during the mining process, it is achieved that the spacing between the conveyor shafts 4 can be changed without manual work, so that the supporting force of the conveyor shaft 4 itself for the conveyor belt 5 can be adjusted, thereby improving the supporting effect of the conveyor shaft 4; under the action of the supporting component 6, during the mining process, it is ensured that after the conveyor belt 5 receives a certain pressure, it can increase the supporting force of the conveyor belt 5 under the support of the supporting plate 601, thereby reducing the pressure of the conveyor belt itself and improving the stability of the conveyor belt 5 itself.

[0030] In one embodiment, for the above-mentioned adjustment component 2, the adjustment component 2 includes a fixed plate 201 symmetrically arranged at the top of the base plate 1, a screw rod 202 is arranged between the two groups of fixed plates 201, a motor 203 matched with the fixed plate 201 is arranged at one end of the screw rod 202, and a limit plate 204 matched with the bracket 3 is arranged at the middle position of the screw rod 202; a limit groove 205 is symmetrically opened at the top of the base plate 1; the shape of the limit groove 205 is a hollow isosceles trapezoid; thereby, the spacing between the conveying shafts 4 can be adjusted.

[0031] The working principle of the adjustment component 2 is as follows: when the detection part 7 senses the support plate 601, the motor 203 is started, and the rotation of the output shaft of the motor 203 drives the screw rod 202 to rotate. Under the rotation of the screw rod 202, the limit plate 204 is driven to move horizontally along the screw rod 202. Under the movement of the limit plate 204, the bracket 3 is driven to move horizontally along the limit groove 205 through the limit bar 302. Under the movement of the bracket 3, the conveying shaft 4 is driven to move horizontally to reduce the spacing between the conveying shafts 4 until the supporting force required by the conveyor belt is reached, so that the detection part 7 cannot sense the support plate 601. Under the action of the detection part 7, the motor 203 is stopped, thereby stopping the change in the spacing between the conveying shafts 4.

[0032] In one embodiment, for the above-mentioned bracket 3, the bracket 3 includes a bracket frame 301 arranged at the top of the base plate 1, and a limiting strip 302 matching the limiting groove 205 is symmetrically arranged at the bottom end of the bracket frame 301, and a support rod 303 is arranged on one side of the bracket frame 301, and a rotating shaft 304 is arranged in the middle position of the support rod 303; the shape of the limiting strip 302 is an isosceles trapezoid; thereby ensuring the stability of the operation of the conveying shaft 4.

[0033] In one embodiment, for the above-mentioned support assembly 6, the support assembly 6 includes a support plate 601 arranged at the bottom end of the conveyor belt 5, and a rotating shaft 2 602 is symmetrically arranged at the bottom end of one side of the support plate, and the rotating shaft 2 602 and the bracket 3 are connected by a fixed rod 603; a rotating shaft 3 604 is arranged at the middle position of the other side of the support plate, and the rotating shaft 3 604 is movably connected with the rotating shaft 1 304 through a sleeve connecting rod 605, and a spring 606 is sleeved on the outer side of the circumference of the sleeve connecting rod 605; thereby increasing the supporting force on the conveyor belt 5.

[0034] In one embodiment, for the above-mentioned detection member 7, the detection member 7 includes a support rod 2 701 arranged on one side of the fixed rod 603, and an infrared sensor 702 cooperating with the support plate 601 is arranged at one end of the support rod 2 701; thereby, the state of the conveyor belt 5 squeezing the support plate 601 can be detected.

[0035] The working principle of the support assembly 6 and the detection member 7 is as follows: when the pressure on the conveyor belt 5 is too great, the squeeze support plate 601 rotates along the rotating shaft 2 602 toward the direction close to the adjustment assembly 2. Under the rotation of the support plate 601, the sleeve connecting rod 605 is squeezed through the rotating shaft 1 304 and the rotating shaft 3 604. Under the squeezing action on the sleeve connecting rod 605, the spring 606 is squeezed. When the support plate 601 rotates to the position where the infrared sensor 702 is located, the sleeve connecting rod 605 reaches the limit of the position that can be shortened, so that the support plate 601 begins to support the conveyor belt 5. At this time, the infrared rays emitted by the infrared sensor 702 are blocked by the support plate 601. The adjusting component 2 is blocked and sends a signal to the adjusting component 2. Under the action of the adjusting component 2, the supporting force of the conveying shaft 4 on the conveying belt 5 is increased by reducing the distance between the conveying shafts 4, so that the pressure of the conveying belt 5 on the supporting plate 601 is reduced. At the same time, under the resetting action of the spring 606, the sleeve connecting rod 605 is extended. Under the extension action of the sleeve connecting rod 605, the supporting plate 601 is driven to rotate along the rotating shaft 602 away from the adjusting component 2, so that the supporting plate 601 leaves the position where the infrared sensor 702 is located, ensuring that the infrared rays emitted by the infrared sensor 702 are not blocked. At this time, the infrared sensor 702 stops sending signals to the adjusting component 2, and the adjusting component 2 stops working.

[0036] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0037] In actual application, when the pressure on the conveyor belt 5 is too large, the squeeze support plate 601 is rotated along the rotating shaft 2 602 toward the direction close to the adjusting component 2. Under the rotation of the support plate 601, the sleeve connecting rod 605 is squeezed through the rotating shaft 1 304 and the rotating shaft 3 604. Under the squeezing action on the sleeve connecting rod 605, the spring 606 is squeezed. When the support plate 601 rotates to the position where the infrared sensor 702 is located, the sleeve connecting rod 605 reaches the limit of the position that can be shortened, so that the support plate 601 begins to support the conveyor belt 5. At this time, the infrared rays emitted by the infrared sensor 702 are blocked by the support plate 601, and a signal is sent to the motor 203 to start the motor 203. Under the rotation of the output shaft of the motor 203, the screw rod 202 is driven to rotate. Under the rotation of the screw rod 202, the limit plate 204 is driven to move horizontally along the screw rod 202. Under the movement of the limit plate 204, the bracket 3 is driven to pass through the limit bar 30 2 moves horizontally along the limit groove 205, and under the moving action of the bracket 3, the conveying shaft 4 is driven to move horizontally, reducing the spacing between the conveying shafts 4. By reducing the spacing between the conveying shafts 4, the supporting force of the conveying shaft 4 on the conveyor belt 5 is increased, so that the pressure of the conveyor belt 5 on the support plate 601 is reduced. At the same time, under the resetting action of the spring 606, the sleeve connecting rod 605 is extended. Under the extension action of the sleeve connecting rod 605, the support plate 601 is driven to rotate along the rotating shaft 2 602 in the direction away from the adjusting component 2, so that the support plate 601 leaves the position where the infrared sensor 702 is located, ensuring that the infrared rays emitted by the infrared sensor 702 are not blocked. At this time, the infrared sensor 702 stops sending signals to the motor 203, and the motor 203 stops working. Under the action of the motor 203 stopping working, the spacing between the conveying shafts 4 stops changing, and the stability of the conveyor belt 5 of the conveyor is detected in real time, so as to prevent the conveyor belt 5 of the conveyor from being torn.

[0038] The working principles of the adjustment component 2, the support component 6 and the detection component 7 are as described above.

[0039] In summary, with the aid of the above-mentioned technical scheme of the utility model, the utility model can detect the squeezing of the conveyor belt 5 on the support plate 601 in real time during mining under the action of the adjusting component 2, the supporting component 6 and the detecting component 7, and when the squeezing reaches a certain degree, adjust the spacing between the conveyor shafts 4, and at the same time, under the support of the supporting component 6, timely increase the supporting force of the conveyor belt 5, thereby avoiding the situation that the conveyor belt 5 is torn, and achieves the effect of preventing the conveyor belt 5 of the conveyor from being torn; under the action of the adjusting component 2, during mining, it is achieved that the spacing between the conveyor shafts 4 can be changed without manual labor, so that the supporting force of the conveyor shaft 4 itself for the conveyor belt 5 can be adjusted, thereby improving the supporting effect of the conveyor shaft 4; under the action of the supporting component 6, during mining, it is ensured that after the conveyor belt 5 receives a certain pressure, it can increase the supporting force of the conveyor belt 5 under the support of the supporting plate 601, thereby reducing the pressure of the conveyor belt itself and improving the stability of the conveyor belt 5 itself.
