Description

Technical Field

[0001] The utility model relates to an anti-tearing device for a transport belt, belonging to the field of anti-tearing devices for belts. Background Art

[0002] In the mining industry, conveyor belts are indispensable machinery. During the mining process, mining belt conveyors can transport ore, slag and other materials from the mining site to the beneficiation plant, or transport the materials after beneficiation to various production workshops. However, in actual production, the conveyor belt is often torn by sharp ores and ironware, causing certain losses to production and increasing the workload of workers for maintenance. In order to detect belt tearing in time and reduce losses, a belt tear prevention device is made based on the phenomena before and after tearing, which can detect belt tearing in a short time. Traditional mechanical belt tear protection devices have poor reliability and stability, and are prone to misoperation under slight disturbances, affecting the normal operation of the conveyor belt. Utility Model Content

[0003] The purpose of the utility model is to solve the problems existing in the prior art and further provide a dust prevention device for the ventilation part of a hydraulic station.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A device for preventing the transport belt from tearing, belonging to the field of belt anti-tear devices. It includes: a support seat, a roller bracket, a roller, a magnetic induction proximity switch, an infrared induction switch and a jacking screw;

[0006] The roller is installed on the support seat, a roller bracket is installed on the roller shaft, a jacking screw is installed at the bottom of the support seat, and the position of the roller is adjusted by the jacking screw on the lower support seat. Two infrared sensing switches are installed on the support seat, and one end of the magnetic induction proximity switch is installed on the roller shaft, and the other end is installed on the support seat.

[0007] Furthermore, when the size of the rotating roller increases, the size of the supporting seat also increases accordingly.

[0008] Furthermore, the portion where the support seat is connected to the roller is two parallel slideways in the vertical direction, and the axis of the roller can move up and down through the slideways.

[0009] Furthermore, the roller bracket is an L-shaped iron plate, and two circular holes are provided on the long side of the roller bracket. The roller shaft passes through the circular hole above the roller bracket and is connected to the support seat, and the other circular hole is fixed to the roller bracket and the support seat with bolts.

[0010] Furthermore, the magnetic induction proximity switch is a device or apparatus having the function of converting a magnetic quantity signal into an electrical signal.

[0011] Furthermore, when installing, the roller should be adjusted to about 10 mm from the belt surface by lifting the screws.

[0012] The beneficial effects of the utility model are:

[0013] The utility model can detect the belt tearing and alarm at the first time when the belt is torn, and then stop the conveyor belt to check the cause and repair the belt, thereby reducing the large-area tearing of the belt caused by untimely detection, and reducing the maintenance cost and the workload of the staff.

[0014] The utility model has two alarm modes at the same time. One is based on the electrical control principle. When the belt is torn, the position of the torn belt protrudes outward to drive the roller to rotate. The magnetic induction proximity switch installed on the support seat will detect the rotation of the roller. The magnetic induction proximity switch is a device or apparatus that has the function of converting magnetic quantity signals into electrical signals. By utilizing the transformation relationship between magnetic quantities and other physical quantities and using the magnetic field as a medium, other non-electrical physical quantities can also be converted into electrical signals to send a signal alarm to the system or monitoring station. The second method is to install infrared sensing switches at both ends of the support seat groove. When the belt is torn, the material will fall out of the tear immediately, and the material will fall into the support seat groove, blocking the infrared rays, and then send a signal to the monitoring station or alarm.

[0019] The utility model will be further described in detail below in conjunction with the accompanying drawings: This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method is given, but the protection scope of the utility model is not limited to the following embodiments.

[0020] like Figure 1 As shown, a dust prevention device for ventilation of a hydraulic station according to this embodiment includes: a support seat 1, a roller bracket 2, a roller 3, a jacking screw 4, an infrared sensor switch 5 and a magnetic induction proximity switch 6;

[0021] The roller 3 is installed on the support base 1, and a roller bracket 2 is installed on the shaft of the roller 3. The position of the roller 3 is adjusted by the lifting screw 4 on the lower support base 1. Two infrared sensing switches 5 are installed on the support base 1, and one end of the magnetic induction proximity switch 6 is installed on the shaft of the roller 3, and the other end is installed on the support base.

[0022] Example 1

[0023] like Figure 1-3 As shown, according to the electrical control principle, a group of magnetic induction proximity switches 6 are installed at one end of the support seat 1 of the anti-tear device, and the other point is installed on the end face of the roller. Before use, the roller 3 is adjusted to about 10 mm away from the belt surface with the jacking screw 4. When the belt is torn, the position of the tear will be pressed down by the weight of the material, so that the position of the belt tear will protrude outward, and the protruding point will produce friction with the roller 3 of the anti-tear device, and the roller 3 will rotate. The magnetic induction proximity switch 6 installed on the support seat will detect the rotation of the roller. The magnetic induction proximity switch converts the magnetic quantity signal into an electrical signal. Through the prior art PLC programming, a red signal is issued when the roller 3 rotates one circle, the PLC system starts counting, and the time relay starts timing. The roller 3 is set to send a signal alarm to the system or monitoring station at the set rotation time to stop the belt. The utility model claims to protect a hardware configuration, which does not need to rely on software implementation, and only needs to judge the voltage conditions of each pin to achieve the purpose of the invention.

[0024] Example 2

[0025] like Figure 1-3 As shown, infrared sensing switches 5 are installed at both ends of the groove of the support seat 1. When the belt is torn, materials will fall out at the tearing point immediately, and the materials will fall into the groove of the support seat 1, blocking the infrared rays, and then send a signal to the monitoring station or alarm to stop the belt from running.

These specific embodiments are different implementations based on the overall concept of the present invention, and the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a technician familiar with the technical field within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
