Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyor equipment, specifically relating to a belt misalignment adjustment device and a belt misalignment adjustment system. Background Technology

[0002] After crushing and screening, bauxite is transported to the stockpile via conveyor belts, with an average conveyor belt capacity of 800 tons per hour. After screening, the bauxite is fed onto the conveyor belt through funnels. Due to space constraints, there is a significant drop between the funnels and the conveyor belt, and ore tends to accumulate in the funnels, making collapses highly likely. Incomplete statistics suggest that collapses may occur up to four times per hour. The impact of these collapses causes the conveyor belt to deviate from its course. If the deviated belt is not adjusted promptly, ore may leak onto the back of the belt, creating a safety hazard. Utility Model Content

[0003] In view of the existing technical problems, the present invention aims to provide a belt misalignment adjustment device and a belt misalignment adjustment system, which can solve the technical problem of how to adjust a misaligned belt.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A belt misalignment adjustment device includes a belt conveyor frame, a belt tensioning roller, a force-applying rod, and two adjusting screws. Both adjusting screws are arranged along the length of the belt conveyor frame. Two sliders are symmetrically arranged along the width of the belt conveyor frame, and both sliders can slide along the length of the belt conveyor frame. The two ends of the belt tensioning roller are rotatably connected to the two sliders respectively. The two adjusting screws are threadedly connected to the two sliders respectively. The outer ends of the adjusting screws extend outwards towards the rear of the belt conveyor frame, and a wheel rudder disc is provided on the outer end of the adjusting screw. Multiple connecting rods are arranged circumferentially on the wheel rudder disc. One end of the force-applying rod has an inwardly facing receiving cavity, through which the force-applying rod is movably inserted into the outer end of the connecting rod.

[0006] In use, the belt misalignment device of this application involves wrapping the belt around the side wall of the belt conveyor tensioning roller, with the belt extending away from the tail of the belt conveyor frame. When the belt rotates, the tensioning roller rotates under the belt's influence. When belt misalignment requires adjustment, a force-applying rod is fitted onto the outer end of the connecting rod, and a force is applied to the force-applying rod. Under the external force of the force-applying rod, the connecting rod drives the wheel hub disc to rotate, thereby causing the adjusting screw to rotate. The screw rotates clockwise or counterclockwise, driving the slider to move along the length of the belt conveyor frame, thus adjusting the position of the belt conveyor tensioning roller and repositioning the misaligned belt. This belt misalignment adjustment device of this invention applies force to the connecting rod on the wheel hub disc via a force-applying rod, thereby adjusting the position of the belt conveyor tensioning roller and repositioning the misaligned belt. This extends the belt's service life and is suitable for use in belt conveyors transporting materials such as ores. The belt misalignment adjustment device of this utility model increases the leverage force of external forces by setting up a force-applying rod and a connecting rod, which can realize the adjustment of belt misalignment by a single person and reduce the labor intensity of the staff.

[0007] Specifically, the rudder disc has a through hole along its thickness direction, and the outer end of the adjusting screw is fixedly installed in the through hole.

[0008] Preferably, the through hole is located on the axial center line of the rudder disk.

[0009] Preferably, the length of the force-applying rod is greater than the length of the connecting rod.

[0010] Specifically, the receiving cavity of the force-applying rod extends along the length of the force-applying rod, and the depth of the receiving cavity is less than or equal to the length of the connecting rod.

[0011] Preferably, the depth of the cavity containing the force-applying rod is no greater than one-fifth of the length of the force-applying rod.

[0012] Specifically, multiple connecting rods are evenly distributed along the circumference on the side wall of the rudder disk.

[0013] Preferably, there are at least four connecting rods.

[0014] Specifically, both ends of the belt tensioning roller are connected to the slider via bearings.

[0015] Based on the same inventive concept, this application also provides a belt misalignment adjustment system, including a belt and the belt misalignment adjustment device as described above. The belt is wrapped around the side wall of the belt conveyor tensioning roller and tensioned by the belt conveyor tensioning roller. The belt extends in a direction away from the tail of the belt conveyor frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The belt misalignment adjustment device of this utility model applies force to the connecting rod on the wheel rudder disc through the force bar, thereby adjusting the position of the belt tensioning drum, so that the misaligned belt is reset and centered, which can extend the service life of the belt. It is suitable for use in belt conveyors for transporting materials such as ore.

[0018] 2. The belt misalignment adjustment device of this utility model increases the leverage force of external forces by setting up a force-applying rod and a connecting rod, which can realize the adjustment of belt misalignment by a single person and reduce the labor intensity of the staff.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0024] like Figure 1As shown, the belt misalignment adjustment device in this embodiment includes a belt conveyor frame 1, a belt tensioning roller 2, a force-applying rod 5, and two adjusting screws 3. Both adjusting screws 3 are arranged along the length of the belt conveyor frame 1. Two sliders 10 are symmetrically arranged along the width direction on the belt conveyor frame 1. The two adjusting screws 3 are respectively connected to the sliders 10 by threads, and the outer ends of the adjusting screws 3 are located on the outer side of the tail of the belt conveyor frame 1. Under the action of the adjusting screws 3, both sliders 10 can slide along the length of the belt conveyor frame 1. The belt tensioning roller 2 is transversely arranged on the belt conveyor frame 1, and both ends of the belt tensioning roller 2 are fixedly connected to the sliders 10 by bearings 9. A wheel rudder disc 4 is provided on the outer end of the adjusting screw 3. Both wheel rudder discs 4 are cylindrical structures cut from 20mm thick steel plates, and a through hole 8 is provided on the axial center line of the wheel rudder disc 4. The outer ends of the adjusting screws 3 are placed inside the through holes 8 and are fixedly connected by welding. Four connecting rods 7 are provided circumferentially on the wheel rudder disk 4, and the four connecting rods 7 are evenly arranged along the circumferential direction of the side wall of the wheel rudder disk 4. The force-applying rod 5 is made of DN50 galvanized pipe with a length of 1.2 meters. One end of the force-applying rod 5 is made into a flat shape, and the inner cavity of this end serves as a receiving cavity for the outer end of the connecting rod 7. The depth of the receiving cavity is one-fifth of the length of the force-applying rod 5, and the force-applying rod 5 is movably inserted into the outer end of the connecting rod 7 through the receiving cavity.

[0025] like Figure 2 As shown, the belt misalignment adjustment system of this embodiment includes a belt 6 and a belt misalignment device as described above. The belt 6 is wrapped around the side wall of the belt conveyor tension roller 2 and is tensioned by the belt conveyor tension roller 2. The belt 6 extends away from the tail of the belt conveyor frame 1. Material is conveyed onto the belt 6 through a funnel 11 located above the belt 6 and is conveyed outward by the belt 6.

[0026] In this embodiment, the belt misalignment adjustment device has two adjustment methods to reset the misaligned belt 6 to the center. The first adjustment method: Facing the tail of the conveyor frame 1, when the belt 6 deviates to the right (i.e., the right side of the belt 6 is slack), adjust the right adjusting screw 3; place the force rod 5 on the connecting rod 7 of the right adjusting screw 3, and rotate the wheel disc 4 clockwise. The wheel disc 4 drives the right adjusting screw 3 to rotate clockwise, causing the slider 10 on that side to move towards the tail of the conveyor frame 1, thereby driving the conveyor tension roller 2 to move backward, so that the deviated belt 6 is reset to the center; when the belt 6 deviates to the left (i.e., the left side of the belt 6 is slack), adjust the left adjusting screw 3; place the force rod 5 on the connecting rod 7 of the left adjusting screw 3, and rotate the wheel disc 4 clockwise. The wheel disc 4 drives the left adjusting screw 3 to rotate clockwise, causing the slider 10 on that side to move towards the tail of the conveyor frame 1, thereby driving the conveyor tension roller 2 to move backward, so that the deviated belt is reset to the center. The second adjustment method: Facing the tail of the conveyor frame 1, when the belt 6 deviates to the right (i.e., the right side of the belt 6 is slack), adjust the left adjusting screw 3; place the force rod 5 on the connecting rod 7 of the left adjusting screw 3, and rotate the wheel disc 4 counterclockwise. The wheel disc 4 drives the left adjusting screw 3 to rotate counterclockwise, causing the slider on that side to move away from the tail of the conveyor frame 1, thereby driving the belt tensioning roller 2 forward, so that the deviated belt 6 is reset and centered. 6. Tension during movement; when belt 6 deviates to the left (i.e., the left side of belt 6 is slack), adjust the right adjusting screw 3; put the force bar 5 on the connecting rod 7 of the right adjusting screw 3, rotate the wheel disc 4 counterclockwise, the wheel disc 4 drives the right adjusting screw 3 to rotate counterclockwise, so that the slider 10 on this side moves away from the tail of the belt conveyor frame 1, thereby driving the belt tensioning roller 2 to move forward, so that the deviated belt 6 is reset to the center, and belt 6 is tensioned during movement.
