Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, in particular to a belt conveyor anti-deviation mechanism. Background Art

[0002] Conveyors are material handling machines that continuously transport materials along a certain route, also known as continuous conveyors. Conveyors can be used for horizontal, inclined, and vertical conveying. Belt deviation is the most common fault in the operation of belt conveyors, which is extremely harmful. When deviation occurs, the friction between the edge of the conveyor and the frame increases, which will wear or tear the conveyor belt and cause equipment accidents. Therefore, it is necessary to monitor it through an anti-deviation device.

[0003] Patent announcement number CN216548036U discloses a belt adjustment anti-deviation structure, including a fixed plate, at least two anti-deviation components and a belt, wherein the anti-deviation components are movably arranged at both ends of the fixed plate, the two anti-deviation components are arranged in parallel, and the belt is transmitted between the two anti-deviation components. The above-mentioned belt adjustment anti-deviation structure can adjust the belt deflection through the anti-deviation components, so that the belt is kept transmitting between the two anti-deviation components. When the belt deflects, one of the anti-deviation components deflects in the direction of the belt deflection, and the other anti-deviation component deflects in the opposite direction to the belt deflection direction, so that the belt is balanced in the running direction, ensuring that the belt will not deviate from the anti-deviation components during operation, and ensuring smooth and fluent operation.

[0004] Although the prior art CN216548036U has many benefits during use, it still has the following problems: it lacks a detection structure for the deviation angle of the conveyor belt, which results in the staff being unable to effectively maintain the conveyor belt in a timely manner. Utility Model Content

[0005] The utility model aims to provide a belt conveyor anti-deviation mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a belt conveyor anti-deviation mechanism, comprising a base plate, a support plate, a connecting block and a sleeve, support plates are installed on both sides of the outer wall of the upper end of the base plate, a sleeve is installed on the outer wall of one side of the support plate, equidistant and parallel transmission rollers are rotatably installed on the outer wall of the upper end of the base plate, a conveyor belt is arranged on the outer wall of the transmission roller, connecting blocks are installed on the outer walls on both sides of the conveyor belt, a slide groove is opened inside the connecting block, a slider is slidably installed inside the slide groove, a connecting rope is installed on the outer wall of one end of the slider, and a counterweight block is installed on the outer wall of one end of the connecting rope.

[0007] When using a belt conveyor anti-deviation mechanism in the present technical solution, the conveyor belt is driven to rotate by an external power structure, and the conveyor belt is supported by a transmission roller. The slider slides inside the slide groove to ensure the relative position stability of the connecting rope and the counterweight block, and prevent the counterweight block from moving with the connecting block. When the conveyor belt deviates, the gravity of the counterweight block drives the slider and the connecting rope to move with it, and the displacement sensor can detect the deviation angle of the conveyor belt.

[0008] Preferably, a displacement sensor is provided on one side of the lower end of the inner wall of the sleeve, and the displacement sensor does not contact the counterweight.

[0009] The displacement sensor detects the moving distance of the counterweight.

[0010] Preferably, both sides of the outer wall of the upper end of the support plate are installed with clamping sleeves, rollers are rotatably installed inside the clamping sleeves, and the connecting rope is located outside the rollers.

[0011] The connecting rope moves inside the roller to ensure smooth movement of the connecting rope.

[0012] Preferably, the size of the counterweight block is smaller than the inner wall size of the sleeve, and the counterweight block is located inside the sleeve.

[0013] Preferably, both sides of the conveyor belt are designed in an inclined shape, and the conveyor belt is in contact with the outer wall of the driving roller.

[0014] Preferably, the inner wall of the slide groove is designed in a stepped shape, and the outer wall of the connecting block is designed in a rectangular shape.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model achieves the effect of detecting the deviation angle of the conveyor belt by setting a connecting rope, a counterweight block and a displacement sensor. The conveyor belt is driven to rotate by an external power structure, and the conveyor belt is supported by a transmission roller. The slider slides inside the slide groove to ensure the relative position stability of the connecting rope and the counterweight block, and prevents the counterweight block from moving with the connecting block. When the conveyor belt deviates, the gravity of the counterweight block drives the slider and the connecting rope to follow the movement. The displacement sensor can detect the deviation angle of the conveyor belt, helping the staff to effectively maintain the conveyor belt in a timely manner, thereby improving the maintenance efficiency of the conveyor belt.
