A device for guiding and adjusting the deviation of a belt conveyor and a method of use

Abstract

This invention relates to a belt conveyor clamping and guiding device and its usage method. It includes a guide roller assembly located on one side of the conveyor belt and two clamping roller assemblies symmetrically positioned vertically relative to the conveyor belt. Each clamping roller assembly includes a vertically movable clamping roller bracket and a clamping spiral roller shafted onto the clamping roller bracket. The clamping spiral roller has spiral protrusions. The guide roller assembly includes a horizontally movable guide roller bracket and a guide roller shafted onto the guide roller bracket. The clamping roller bracket is connected to the guide roller bracket via a connecting rod assembly. When the conveyor belt deviates towards the guide roller, it pushes the guide roller and guide roller bracket away from the conveyor belt. The connecting rod assembly drives the two clamping spiral rollers to clamp the conveyor belt, causing them to rotate. The spiral protrusions on the clamping spiral rollers cause the conveyor belt to move in the opposite direction of the deviation, returning the conveyor belt to its normal track along the spiral direction, thus achieving the belt alignment operation.

Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, specifically to a belt conveyor clamping and guiding device and its usage method. Background Technology

[0002] Belt conveyors are widely used in the manufacturing industry to transport bulk materials such as coal and ore. Because belt conveyors use equipment such as stacker-reclaimers or unloading vehicles, a section of the conveyor belt is suspended and does not come into contact with the material. There is no good way to prevent this section of the conveyor belt from running off-track. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a belt-clamping and guiding device for belt conveyors and its usage method.

[0004] This invention is achieved through the following technical solution: a belt-clamping and guiding device for a belt conveyor is provided, comprising a guide roller assembly located on one side of the conveyor belt and two clamping roller assemblies symmetrically positioned above and below the conveyor belt. The clamping roller assembly includes a clamping roller bracket that moves vertically and a horizontal clamping spiral roller axially connected to the clamping roller bracket. The clamping spiral roller has spiral protrusions. The guide roller assembly includes a guide roller bracket that moves horizontally along the conveyor belt and a guide roller axially connected to the guide roller bracket. The clamping roller bracket is connected to the guide roller bracket via a connecting rod assembly. When the guide roller bracket moves away from the conveyor belt, the connecting rod assembly drives the clamping roller bracket to move towards the conveyor belt.

[0005] In this design, the conveyor belt is positioned between two clamping spiral rollers. When the conveyor belt deviates towards the guide roller, it pushes the guide roller and its support away from the conveyor belt. As the guide roller support moves away from the conveyor belt, it drives the clamping roller support to move towards the conveyor belt via a linkage assembly. This causes the two clamping spiral rollers to clamp the conveyor belt, thereby rotating the two clamping spiral rollers. The spiral protrusions on the clamping spiral rollers cause the conveyor belt to move in the opposite direction of the deviation, thus correcting the deviation and returning it to the normal track along the spiral direction.

[0006] As an optimization, the connecting rod assembly includes a fixed support shaft, an arc-shaped plate hinged to the support shaft, and a support wheel axially connected to the guide roller bracket. One end of the arc-shaped plate is hinged to the clamping roller bracket, and the support wheel is in contact with the other end of the arc-shaped plate. In this design, the support wheel on the guide roller bracket pushes the ends of the two arc-shaped plates outward, thereby causing the other end of the arc-shaped plate to move inward.

[0007] As an optimization, the support wheel is positioned on the side of the arc-shaped plate closest to the conveyor belt, and the center of the arc-shaped plate is located on the same side. In this design, the support wheel is positioned on the side of the arc-shaped plate closest to the conveyor belt, and the two arc-shaped plates are pushed outward by the support wheel.

[0008] As an optimization, a torsion spring is installed on the hinge shaft of the clamping roller bracket and the arc-shaped plate. In this design, the torsion spring presses the arc-shaped plate firmly against the support wheel.

[0009] As an optimization, a connecting rod is fixedly connected to the inner side of the arc-shaped plate, and the arc-shaped plate is hinged to the support shaft via the connecting rod. In this solution, the arc-shaped plate is hinged to the support shaft via the connecting rod.

[0010] As an optimization, an elastic reset mechanism is also included to push the guide roller bracket towards the conveyor belt. In this solution, the elastic reset mechanism pushes the guide roller bracket towards the conveyor belt, so that when the conveyor belt returns to its original position, the guide roller bracket also returns to its original position along with the conveyor belt.

[0011] As an optimization, the clamping spiral roller is rotatably connected to the spiral roller shaft, and the two ends of the spiral roller shaft are respectively slidably connected to the clamping roller bracket. Both ends of the spiral roller shaft are equipped with floating springs that press the ends of the spiral roller shaft together.

[0012] A method for using a belt conveyor clamping and guiding device includes the following steps:

[0013] a. The conveyor belt is between two clamping spiral rollers. When the conveyor belt deviates towards the direction of the guide roller, it pushes the guide roller and the guide roller bracket away from the conveyor belt.

[0014] b. The support wheels on the retaining roller bracket push the ends of the two arc-shaped plates outward, thereby causing the other end of the arc-shaped plates to move inward, which in turn drives the two clamping roller brackets to move inward, clamping the conveyor belt through the two clamping spiral rollers, thereby driving the two clamping spiral rollers to rotate.

[0015] c. The spiral protrusions on the clamping spiral roller cause the conveyor belt to move in the opposite direction of the deviation, thereby adjusting the deviation and returning it to the normal track along the spiral direction.

[0016] The beneficial effects of the present invention are as follows: The belt clamping and guiding adjustment device and its usage method for a belt conveyor of the present invention, when the conveyor belt deviates towards the direction of the guide roller, pushes the guide roller and the guide roller bracket to move away from the conveyor belt, and drives the clamping roller bracket to move towards the direction of the conveyor belt through the connecting rod assembly. The two clamping spiral rollers clamp the conveyor belt and drive the two clamping spiral rollers to rotate. The spiral protrusions on the clamping spiral rollers cause the conveyor belt to move in the opposite direction of the deviation, so that the conveyor belt returns to the normal track along the spiral direction, thereby realizing the belt adjustment operation.

[0023] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0024] like Figures 1-4 As shown, a belt conveyor clamping and guiding device of the present invention includes a guide roller assembly located on one side of the conveyor belt 9 and two clamping roller assemblies symmetrically arranged above and below the conveyor belt 9. The clamping roller assembly includes a clamping roller bracket 1 that moves up and down and a horizontal clamping spiral roller 2 axially connected to the clamping roller bracket 1. The rotation axis of the clamping spiral roller 2 is perpendicular to the conveying direction of the conveyor belt 9. Therefore, after the conveyor belt 9 is in contact with the clamping spiral roller 2, it drives the clamping spiral roller 2 to rotate. The clamping spiral roller 2 is provided with spiral protrusions, and the spiral protrusions of the two clamping spiral rollers 2 are symmetrically arranged above and below.

[0025] like Figure 3 As shown, when the clamping spiral roller 2 clamps the conveyor belt 9, the spiral protrusion drives the conveyor belt 9 to move to the right to achieve the deviation adjustment.

[0026] like Figure 2 , 3 As shown, the conveyor belt 9 tends to shift to the left in the figure, so the guide roller assembly is located on the left side of the conveyor belt 9.

[0027] The roller baffle assembly includes a roller baffle bracket 4 that moves in the left-right direction along the conveyor belt 9 and a roller baffle 5 that is axially connected to the roller baffle bracket 4. The roller baffle bracket 4 is a vertical shaft, and the roller baffle 5 is rotatably connected to the vertical shaft.

[0028] The clamping roller bracket 1 is connected to the guide roller bracket 4 via a connecting rod assembly. When the guide roller bracket 4 moves away from the conveyor belt 9, it drives the clamping roller bracket 1 to move towards the conveyor belt 9 via the connecting rod assembly.

[0029] Specifically, the linkage assembly includes a fixed support shaft 8, an arc plate 3 hinged to the support shaft 8, and a support wheel 6 axially connected to the guide roller bracket 4. The support shaft 8 is fixed in any position, and the arc plate 3 extends left and right. When the left end of the arc plate 3 swings upward, the right end of the arc plate 3 swings downward.

[0030] One end of the arc-shaped plate 3 is hinged to the clamping roller bracket 1, and the support wheel 6 is attached to the other end of the arc-shaped plate 3. The support wheel 6 is located on the side of the arc-shaped plate 3 near the conveyor belt 9, and the center of the arc-shaped plate 3 is located on the side of the arc-shaped plate 3 near the conveyor belt 9.

[0031] A torsion spring is installed on the hinge shaft of the clamping roller bracket 1 and the arc plate 3. The arc plate is pressed tightly against the support wheel.

[0032] A connecting rod 7 is fixedly connected to the inner side of the arc-shaped plate 3, and the arc-shaped plate 3 is hinged to the support shaft 8 through the connecting rod 7.

[0033] The clamping roller bracket 1 moves up and down, and the guide structure for its up and down movement is not limited. In this application, the up and down movement of the clamping roller bracket 1 does not mean that it must move up and down horizontally. In this embodiment, the clamping roller bracket 1 is also allowed to move left and right a certain distance to adapt to the trajectory of the hinge point with the arc plate 3.

[0034] For example, the clamping roller bracket 1 can be guided to move up and down through the structure of a vertical guide shaft and a guide sleeve, wherein the inner diameter of the guide sleeve is larger than the outer diameter of the guide shaft, so that the clamping roller bracket 1 can move left and right a certain distance.

[0035] For example, the clamping roller bracket 1 can also be connected by several parallel springs, with one end of the spring connected to the clamping roller bracket 1 and the other end fixedly connected to a fixed top plate or equipment. Thus, the clamping roller bracket 1 can move up and down by the extension and retraction of the springs.

[0036] The roller support 4 moves left and right along the conveyor belt 9. The limiting structure for the left and right movement of the roller support 4 is not limited, and the left and right guidance of the roller support 4 can be achieved by the slider rail.

[0037] It also includes an elastic reset mechanism that pushes the guide roller bracket 4 to move in the direction of the conveyor belt 9. In this embodiment, the elastic reset mechanism is a spring, which pushes the guide roller bracket 4 to move in the direction of the conveyor belt 9 to achieve the return to its original position.

[0038] The clamping spiral roller 2 is rotatably connected to the spiral roller shaft 10. Both ends of the spiral roller shaft 10 slide onto the clamping roller bracket 1, one above the other. Both ends of the spiral roller shaft 10 are equipped with floating springs 11 that press down on the ends of the spiral roller shaft 10. Specifically, as follows... Figure 4 As shown, the clamping roller bracket 1 has a vertical elongated hole. The end of the spiral roller shaft 10 is inserted into the elongated hole, so it can slide up and down. A floating spring 11 is installed between the lower end of the spiral roller shaft 10 and the lower end face of the elongated hole. A floating spring 11 is also installed between the upper end of the spiral roller shaft 10 and the upper end face of the elongated hole. Therefore, the clamping spiral roller 2 can have a certain vertical elasticity relative to the clamping roller bracket 1. As a result, the contact time between the clamping spiral roller 2 and the conveyor belt 9 is longer, and the adjustment effect is better.

[0039] How to use this invention:

[0040] The conveyor belt 9 is positioned between two clamping spiral rollers 2. When the conveyor belt 9 deviates towards the guide roller 5, it pushes the guide roller 5 and the guide roller bracket 4 away from the conveyor belt 9. The support wheel 6 on the guide roller bracket 4 pushes the ends of the two arc plates 3 outward, thereby causing the other end of the arc plates 3 to move inward, which in turn drives the two clamping roller brackets 1 to move inward. The two clamping spiral rollers 2 clamp the conveyor belt 9, thereby causing the two clamping spiral rollers 2 to rotate. The spiral protrusions on the clamping spiral rollers 2 cause the conveyor belt 9 to move in the opposite direction of the deviation, thus achieving deviation adjustment and returning to the normal track along the spiral direction.
