Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a deviation sensor for a mining belt conveyor. Background Art

[0002] Mining conveyor belts are a vital conveying device widely used in mining and industrial applications. They efficiently and efficiently transport large quantities of materials such as coal and ore, significantly improving production efficiency and reducing labor costs. To monitor belt deviation, deviation sensors are often installed at appropriate locations along the conveyor belt. When the conveyor belt deviates, one side of the belt pushes against the sensor's probe, causing the internal circuit to output a low-level signal, shutting off the power to the conveyor belt and providing protection against deviation.

[0003] Existing mining belt conveyor deviation sensors are usually installed by directly fixing them to the brackets set on the side of the belt conveyor with bolts. However, the bracket structure set on the side of the belt conveyor is fixed, so there are the following defects when installing the deviation sensor:

[0004] Since the bracket structure for installing the deviation sensor is fixed, the angle of the deviation sensor is fixed after it is installed on the bracket. However, when the bracket for installing the deviation sensor is fixed to the belt conveyor through welding or other means, the bracket angle may deviate. Or, due to various factors in the mine, the bracket may be collided, causing the bracket angle to deviate. As a result, after the deviation sensor is installed on the bracket, the probe rod of the deviation sensor is not parallel to the belt, and the angle of the deviation sensor is difficult to adjust, which affects the accuracy of the deviation sensor. Utility Model Content

[0005] The purpose of the present invention is to at least solve one of the technical defects described in the background technology.

[0006] To this end, one purpose of the present invention is to propose a deviation sensor for a mining belt conveyor, which aims to solve the problem in the prior art that the angle of the deviation sensor is difficult to adjust, thereby affecting the accuracy of the deviation sensor.

[0007] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the present utility model provides a mining belt conveyor deviation sensor, comprising a housing, an adjustment plate rotatably connected to the back of the housing, a support fixedly connected to the bottom of the adjustment plate, a positioning screw fixedly connected to the side of the support close to the housing, a positioning plate fixedly connected to the bottom of the housing, an arc-shaped groove formed on the side of the positioning plate, the positioning screw slidingly inserted in the arc-shaped groove, and a nut threadedly connected to the outer surface of the positioning screw;

[0008] The back side of the adjusting plate is slidably connected to a base, and the base is fixedly connected to two symmetrical connecting seats on one side close to the adjusting plate. Circular holes are provided on the sides of the two connecting seats, and adjusting screws are rotatably connected in the circular holes of the two connecting seats. One end of the adjusting screw is fixedly connected to a rotating head, and a threaded sleeve is fixedly connected to the back side of the adjusting plate. The threaded sleeve is threadedly connected to the outer surface of the adjusting screw, and fixing ears are fixedly connected to the four corners of the base.

[0009] The beneficial effect is: after the shell is fixed to the bracket on the side of the belt conveyor through the fixing ear on the base, the shell can be rotated through the rotating shaft to adjust the inclination angle of the probe rod above the shell, and then the inclination angle of the shell can be fixed by tightening the nut. By rotating the adjusting screw, the adjusting plate can slide relative to the base, so that the distance between the probe rod on the shell and the belt of the belt conveyor can be adjusted. Therefore, even if the angle of the side bracket of the belt conveyor deviates, the probe rod can be made parallel to the belt and maintain an appropriate distance through corresponding adjustment, thereby ensuring the accuracy of the deviation sensor.

[0010] Preferably, any of the above schemes is that a rubber pad is fixedly connected to the front side of the positioning plate, a gasket is sleeved on the outer surface of the positioning screw, and a convex strip is fixedly connected to one side of the gasket.

[0011] The beneficial effect is that when the nut is tightened, the nut presses the gasket, and the convex strips on the side of the gasket can sink into the rubber pad, thereby avoiding the problem of sliding of the positioning screw and improving the firmness.

[0012] Preferably, any of the above schemes is that the outer surface of the rotating head is sleeved with a positioning sleeve, the outer surface of the rotating head is provided with a first tooth groove, the inner wall of the positioning sleeve is fixedly connected with a rack, a side surface of a connecting seat located on one side of the rotating head is provided with a socket, and the inner wall of the socket is provided with a second tooth groove.

[0013] The beneficial effect is: after the shell is installed and adjusted, the positioning sleeve can be inserted into the socket by sliding it, so that the rack engages with the first tooth groove and the second tooth groove at the same time, so that the adjusting screw cannot rotate. Therefore, the vibration of the belt conveyor during operation will not cause the adjusting screw to rotate, thereby avoiding the problem of displacement of the shell due to vibration, and improving the reliability of the structure.
