Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of belt conveyor alignment devices, specifically to a manual precision alignment device for belt conveyors. Background Technology
[0002] Belt conveyors are widely used in various sectors of social production for transporting materials. However, during operation, belt misalignment along the axial direction of the idlers is inevitable. This misalignment not only causes material spillage but also accelerates belt wear, severely impacting the belt's service life. Therefore, belt alignment devices are widely used on belt conveyors for correction. The lower side of the alignment device is mounted on the belt conveyor frame via a vertically arranged rotation center. The alignment device idler, along with the original idlers of the belt conveyor, supports the belt movement. When the belt misaligns, the friction between one edge of the belt and the alignment device idler increases. This friction causes the alignment device to deflect around the rotation center, causing the idler on that side to shift forward. This increases the lateral reaction force of the idler on that side on the belt, thus moving the belt in the opposite direction of the misalignment. When the belt moves to the center position, the alignment device stops deflecting.
[0003] However, in actual use, the aforementioned belt alignment device only achieves its correction function when the belt deviates to a significant extent and sufficient friction is generated between the belt edge and the alignment device's rollers to deflect the belt. The correction accuracy is poor, and the belt still experiences prolonged wear during this process. Furthermore, after correction, the alignment device cannot automatically return to its original position, and the correction time is even longer when the belt deviates to the other side.
[0004] In addition, in fields such as coal conveying systems, the working environment of the belt shifter is harsh and affected by dust. The rotation center of the belt shifter is prone to jamming. In this case, the friction required to make the belt shifter deflect is greater, the belt wear is more severe, and the belt cannot be corrected in time. Utility Model Content
[0005] The technical problem to be solved by this utility model is: how to correct belt deviation in a timely manner and improve the accuracy of deviation correction.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0007] This utility model provides a manual precision belt conveyor alignment device, including a belt conveyor, an alignment device on the belt conveyor, an alignment handle hinged to one end of the alignment device, the alignment handle being arranged along the running direction of the belt conveyor and being able to deflect up and down around its own hinge axis, a fastener being fixed on the frame of the belt conveyor and located below the alignment handle, the fastener being able to engage with the fastener when the alignment handle deflects down around its own hinge axis.
[0008] The beneficial effects of this utility model are:
[0009] This invention allows for timely belt correction when the belt deviates from its designated position. Operators can adjust the belt alignment by pushing or pulling the adjustment handle to rotate the belt around its center of rotation. The belt alignment does not rely on belt friction for operation, and can correct even minor belt deviations, improving accuracy and preventing prolonged belt wear before operation. After correction, the adjustment handle allows for timely return of the belt alignment to its original position. Furthermore, even if the belt alignment experiences jamming at its center of rotation, it does not affect timely control, extending its lifespan and reducing costs.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] Furthermore, the fastener is arranged vertically, with its lower end fixed to the frame of the belt conveyor and its upper end inclined away from the belt; when the adjustment handle deflects downward around its own hinge axis, it can be engaged on the side of the fastener facing the belt.
[0012] When the alignment device deflects, the alignment handle follows the deflection of the alignment device, thus moving closer to or further away from the fastener. When the alignment handle is close to the fastener, it can be engaged at the upper part of the fastener; when the alignment handle is far away from the fastener, it can be engaged at the lower part of the fastener. Thus, the operator can judge the status of the alignment device based on the height of the alignment handle, reducing the time required for personnel to monitor the device.
[0013] Furthermore, the buckle has multiple slots on the side facing the belt, and the multiple slots are distributed in the vertical direction; when the adjustment handle deflects downward around its own hinge axis, the lower edge of the adjustment handle can enter the slot and engage with the bottom of the slot.
[0014] The slot accommodates the lower edge of the adjustment handle, preventing the adjustment handle from sliding up and down due to a large gap in the connection, which would cause the angle of the adjuster to change and improve the stability of the adjustment handle connection.
[0015] Furthermore, the side of the buckle facing the belt is a flat plate structure, and the buckle groove is located at the edge of the flat plate structure.
[0016] The lower edge of the adjustment handle only needs a small gap to be snapped onto the flat structure, making it easy to process, easy to snap into, and with good stability.
[0017] Furthermore, the fastener is made of angle steel.
[0018] One flat plate structure of the angle steel is used to snap onto the adjustment handle, making snapping easy. The other flat plate structure is parallel to the adjustment handle and can withstand the force of the adjustment device's deflection, preventing deformation of the fasteners and improving stability.
[0019] Furthermore, the lower side of the adjustment handle is provided with multiple locking teeth.
[0020] When the adjustment handle is turned downwards, the locking teeth can engage with the locking element, ensuring high reliability.
[0021] Furthermore, the adjustment handle is machined from a sheet metal.
[0022] The sheet metal is easy to drill holes in, making it easy to hinge the adjustment handle and the adjustment device; at the same time, the locking teeth can be formed simply by cutting a groove on the underside of the adjustment handle with a grinding wheel, making the processing convenient.
[0023] Furthermore, one end of the adjustment handle is hinged to the adjustment device, and the other end is provided with an arc-shaped grip, with arc-shaped grooves on both sides of the grip.
[0024] The rounded grip and groove design prevent sharp structures from injuring your hands and make it easier to grip and use for leverage.
[0025] Furthermore, the adjuster is also provided with a hinge pad, and the hinge pad is provided with a hinge bolt. One end of the adjuster handle is provided with a hinge hole, and the hinge bolt and the hinge hole are fitted with a clearance fit.
[0026] The adjustment handle is hinged by bolts, which prevents it from coming off the belt. The clearance fit between the hinge bolt and the hinge hole reduces the rotational resistance of the adjustment handle and allows it to swing close to or away from the belt within a small range, thus avoiding structural interference.
[0027] Furthermore, the alignment device includes an alignment device bracket, a bearing plate is provided in the lower middle part of the alignment device bracket, and the bearing plate is connected to the frame of the belt conveyor; a horizontal idler and an inclined idler are provided on the upper side of the alignment device bracket, and the inclined idler is located on both sides of the horizontal idler and arranged in a V shape.
[0028] When the belt conveyor is working normally, the horizontal idler and the belt conveyor idler together support the belt movement. The inclined idler can support the edge of the belt or not contact the belt. When the belt runs off track, the tracker can be operated to rotate around the bearing plate. The inclined idler on the side of the belt that is running off track generates a lateral reaction force on the belt, which facilitates timely correction of the belt. The belt is connected to the frame of the belt conveyor through the bearing plate, resulting in low rotational resistance and preventing jamming. Attached Figure Description

[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0034] This utility model refers to Figure 1-2 .
[0035] This utility model provides a manual precision belt conveyor alignment device, including a belt conveyor, an alignment device on the belt conveyor, an alignment handle 3 hinged to one end of the alignment device, the alignment handle 3 is arranged along the running direction of the belt conveyor and can deflect up and down around its own hinge axis, a fastener 2 is fixed on the frame 1 of the belt conveyor and located below the alignment handle 3, the alignment handle 3 can be engaged with the fastener 2 when it deflects down around its own hinge axis.
[0036] principle:
[0037] When the belt slips off-center, the operator simply needs to grasp and lift the adjusting handle 3, disengaging it from the fastener 2. Then, by pushing or pulling the adjusting handle 3, the belt adjuster can be rotated around its center of rotation, increasing the lateral reaction force of the belt adjuster roller on the off-center side and causing the belt to move in the opposite direction of the slippage. When the belt moves to the center position, the adjusting handle 3 can be pushed or pulled back to its original position, reducing wear on the belt. During normal belt operation, if the belt adjuster needs to be fixed, the adjusting handle 3 is engaged with the fastener 2; if the belt adjuster needs to maintain its automatic adjustment function, the adjusting handle 3 can be rotated around its hinge axis to the side away from the fastener 2.
[0038] By employing this invention, when the belt deviates from its designated position, the operator can push or pull the adjustment handle 3 to rotate the belt adjuster around its center of rotation, thereby promptly correcting the belt's deviation. The belt adjuster does not rely on the belt's friction for operation, and can correct even minor belt deviations, improving correction accuracy and preventing prolonged belt wear before the adjuster's operation. After correction, the belt adjuster can be promptly returned to its original position via the adjustment handle 3. Furthermore, even if the belt adjuster's center of rotation experiences jamming, it does not affect timely control of the adjuster's operation, delaying its wear and tear and reducing costs.
[0039] Furthermore, the buckle 2 is arranged vertically, with its lower end fixed to the frame 1 of the belt conveyor and its upper end tilted away from the belt. When the adjustment handle 3 is deflected downward around its own hinge axis, it can be engaged with the buckle 2 on the side facing the belt.
[0040] When the alignment device deflects, the alignment handle 3 deflects along with the alignment device, thus moving closer to or further away from the fastener 2. When the alignment handle 3 is close to the fastener 2, it can be engaged at the upper part of the fastener 2; when the alignment handle 3 is far away from the fastener 2, it can be engaged at the lower part of the fastener 2. Thus, the operator can judge the status of the alignment device based on the height of the alignment handle 3, reducing the time required for personnel to monitor the device.
[0041] Furthermore, the buckle 2 has multiple slots 5 on the side facing the belt, and the multiple slots 5 are distributed in the vertical direction; when the adjustment handle 3 deflects downward around its own hinge axis, the lower edge of the adjustment handle 3 can enter the slot 5 and be engaged at the bottom of the slot 5.
[0042] The slot 5 accommodates the lower edge of the adjustment handle 3, preventing the adjustment handle 3 from sliding up and down due to a large gap in the connection, which would cause the angle of the adjuster to change and improve the stability of the connection of the adjustment handle 3.
[0043] Furthermore, the side of the buckle 2 facing the belt is a flat plate structure, and the slot 5 is located at the edge of the flat plate structure.
[0044] The lower edge of the adjustment handle 3 only needs a small gap to be snapped onto the flat structure, which is convenient to process, easy to snap onto, and has good stability.
[0045] Furthermore, the buckle 2 is made of angle steel.
[0046] One flat plate structure of the angle steel is used to snap onto the adjustment handle 3, which is easy to snap onto. The other flat plate structure is parallel to the adjustment handle 3 and can withstand the force of the adjustment device's deflection, preventing the buckle 2 from deforming and improving stability.
[0047] Furthermore, the lower side of the adjustment handle 3 is provided with multiple locking teeth 4.
[0048] When the adjustment handle 3 is turned downwards, the locking teeth 4 can engage with the locking piece 2, ensuring good reliability.
[0049] Furthermore, the adjustment handle 3 is machined from a sheet metal.
[0050] The plate is easy to drill holes, making it easy to achieve the hinge connection between the adjustment handle 3 and the adjustment device; at the same time, the tooth 4 can be formed simply by cutting a groove on the lower side of the adjustment handle 3 with a grinding wheel, which is convenient for processing.
[0051] Furthermore, one end of the adjustment handle 3 is hinged to the adjustment device, and the other end is provided with an arc-shaped grip 6, with arc-shaped grooves on both sides of the grip 6.
[0052] The rounded grip and groove design prevent sharp structures from injuring your hands and make it easier to grip and use for leverage.
[0053] Furthermore, the skew adjuster is also provided with a hinge pad 7, and a hinge bolt 8 is provided on the hinge pad 7. One end of the skew adjustment handle 3 is provided with a hinge hole, and the hinge bolt 8 is clearance-fitted with the hinge hole.
[0054] The adjustment handle 3 is hinged by bolts, and the bolt head can prevent the adjustment handle 3 from coming off. The hinge bolt 8 and the hinge hole are fitted with a clearance, which makes the rotation resistance of the adjustment handle 3 small and allows it to swing close to or away from the belt within a small range, thus avoiding structural interference.
[0055] Furthermore, the alignment device includes an alignment device bracket 9, and a bearing disk 10 is provided in the lower middle part of the alignment device bracket 9. The bearing disk 10 is connected to the frame 1 of the belt conveyor. A horizontal idler roller 11 and an inclined idler roller 12 are provided on the upper side of the alignment device bracket 9. The inclined idler roller 12 is located on both sides of the horizontal idler roller 11 and is arranged in a V-shape.
[0056] When the belt conveyor is working normally, the horizontal idler 11 and the belt conveyor idler 13 support the belt movement together. The inclined idler 12 can support the edge of the belt or not contact the belt. When the belt runs off-track, the belt adjuster can be operated to rotate around the bearing plate 10. The inclined idler 12 on the side of the belt running off-track generates a lateral reaction force on the belt, which facilitates timely belt correction. The belt is connected to the frame 1 of the belt conveyor through the bearing plate 10, resulting in low rotational resistance and preventing jamming.
