Description

Technical Field

[0001] The invention relates to the technical field of belt conveyor deviation correction, in particular to a damping return protection device. Background Art

[0002] Belt deviation is a common phenomenon in belt conveyors. It can be caused by many factors such as improper installation of various parts of the belt conveyor, inefficient operation, and material impact direction. Belt deviation is not only easy to cause material spillage and belt wear, affecting its service life, but in severe cases it is also easy to cause safety hazards such as belt breakage.

[0003] In response to the above problems, a damping return protection device will be added to automatically correct the belt when it deviates and return the belt to the right position, so that the belt can stably transport materials. At present, the installation methods of the correcting roller and the limiting roller in the damping return protection device are mainly divided into fixed installation and adjustable installation. The fixed installation method has a simple structure and good stability, but it is difficult to provide the best support for belts with different bandwidths or different load conditions, which will limit the flexibility of the system. The adjustable installation can adjust the inclination angle of the correcting roller and the spacing of the limiting roller according to actual needs, and adapt to belts with different bandwidths and load conditions within a certain range. However, the existing adjustment method may require the removal of the fastening bolts one by one and then moving the angle of the correcting roller and the position of the limiting roller. After moving to the adjustment position, the fastening bolts are tightened again to fix it. The entire conveyor line includes multiple correcting rollers and limiting rollers, with low adjustment efficiency and large workload. Moreover, because the correcting rollers and limiting rollers are symmetrically distributed, it is difficult to ensure the consistency of the adjustment process. If a number of actuators such as electric pushers and hydraulic cylinders are set to adjust the positions of the correcting rollers and limiting rollers, the investment cost and the adjustment cost are higher. Summary of the invention

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0029] See also Figure 1 and Figure 2A damping return protection device includes a plurality of adjustment units 4, a control unit 5, a return unit and a connection unit 6. The return units are evenly distributed along the conveying direction of the conveyor belt 8. The adjustment units 4 and the return units correspond one to one. The control unit 5 corresponds one to one with the adjustment unit 4 and controls the adjustment unit 4 to complete the adjustment work. The connection unit 6 is respectively located between adjacent control units 5 and connects two adjacent control units 5 together to form a control system that is easy to operate uniformly. The return unit includes a roller 1, an inclined deviation correction roller 2 and a vertically set limit roller 3. The roller 1 is horizontally installed on a frame 7. The deviation correction roller 2 and the limit roller 3 are symmetrically distributed on the left and right, and the symmetrically distributed limit roller 3 is located on the front side of the roller 1, and the deviation correction roller 2 is located on the rear side of the roller 1. The conveyor belt 8 is transported from back to front, such as Figure 1 As shown, when the conveyor belt 8 deviates from the center, it will hit the vertical limiting roller 3 to generate friction damping and generate a reaction force on the conveyor belt 8. At the same time, the conical structure of the correcting roller 2 will automatically correct the conveyor belt 8, so that the conveyor belt 8 can quickly return to the center, ensuring the stability of the conveying of the conveyor belt 8. Among them, the control unit 5 controls the adjustment unit 4 to synchronously adjust the inclination angle of the correcting roller 2 and the distance between the symmetrical limiting rollers 3. The connecting unit 6 connects all the control units 5 together to form a control system that is easy to operate in a unified manner and synchronously controls all the adjustment units 4 to perform the adjustment work in a unified manner. Compared with the existing adjustment method, the efficiency of the adjustment process and the convenience of adjustment are effectively improved.

[0030] See also Figure 1 , Figure 2 and Figure 4 The adjustment unit 4 includes an adjustment component 1 for adjusting the tilt state of the deviation correction roller 2, an adjustment component 2 for adjusting the spacing of the limiting rollers 3, a first mounting seat 48 for mounting the adjustment component 1, and a second mounting seat 49 for mounting the adjustment component 2. The first mounting seat 48 and the second mounting seat 49 are both mounted on the frame 7. The adjustment component 1 and the adjustment component 2 both include a sliding seat 41 symmetrically arranged on the left and right, an adjustment screw 42 for controlling the synchronous reverse movement of the sliding seat 41, a fixing member 43 pressed against the sliding seat 41, and a control member 44 for controlling the pressing state of the fixing member 43. The fixing members 43 are symmetrically distributed and clamped against the sliding seat 41. The control member 44 is slidably arranged and controls the pressing state of the fixing member 43 by wedging with the fixing member 43. Figure 4As shown, the sliding seat 41 in the adjustment component 1 is slidably connected to the first mounting seat 48 left and right, and the stabilizing members 43 are symmetrically distributed front and back and slidably connected to the first mounting seat 48 front and back, and the stabilizing members 43 symmetrically distributed front and back are respectively located on both sides of the sliding seat 41. During the adjustment process, the stabilizing members 43 and the sliding seat 41 are not in a tightly pressed state, which is convenient for the smooth sliding of the sliding seat 41. After the adjustment is completed, the stabilizing members 43 are respectively pressed against the sliding seat 41 from the front and back sides to improve the stability of the position state of the sliding seat 41. A support member 46 is hinged on the sliding seat 41, and the support member 46 is hinged to the middle of the central axis of the deviation correcting roller 2. The end of the central axis of the deviation correcting roller 2 is hingedly mounted on the first mounting seat 48, and the corresponding adjusting screw 42 is rotatably connected to the first mounting seat 48 and is threadedly connected to the corresponding sliding seat 41. Figure 2 and Figure 4 As shown, by rotating the adjusting screw 42 , the symmetrical sliding seat 41 can be synchronously controlled to move in the opposite direction. The sliding seat 41 moves to adjust the angle of the deviation-correcting roller 2 through the supporting member 46 .

[0031] See also Figure 2 and Figure 3 The sliding seat 41 in the adjustment component 2 is slidably connected to the second mounting seat 49 left and right, and the stabilizing member 43 is symmetrically distributed up and down and slidably connected to the second mounting seat 49 up and down. The corresponding adjusting screw 42 is rotatably connected to the second mounting seat 49 and is threadedly connected to the sliding seat 41. The limiting roller 3 is fixedly mounted on the sliding seat 41. The adjusting screw 42 is rotated to control the symmetrical sliding seat 41 to slide synchronously in the opposite direction to adjust the spacing of the limiting rollers 3. Similarly, during the adjustment process, the stabilizing member 43 and the sliding seat 41 are not in a tightly pressed state, which facilitates the smooth adjustment of the sliding seat 41. After the adjustment is completed, the stabilizing member 43 rests on the sliding seat 41 from the upper and lower sides respectively to improve the stability of the sliding seat 41.

[0032] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The control member 44 includes a sliding frame 442 provided with a plurality of wedge-shaped blocks 441, the sliding frame 442 is a U-shaped frame structure, and the stabilizing member 43 is provided with a wedge-shaped groove 443, which is a groove body provided with an inclined surface (such as Figure 5 As shown), the wedge-shaped groove 443 corresponds to the wedge-shaped block 441 one by one, as shown Figure 5As shown, the wedge-shaped groove 443 and the wedge block 441 are provided with inclined surfaces that are wedged with each other, and the inclined surfaces gradually move away from the middle adjusting screw 42 from left to right, wherein the sliding frame 442 in the adjusting component one is slidably connected to the first mounting seat 48 left and right, and the sliding frame 442 in the adjusting component two is slidably connected to the second mounting seat 49 left and right. Taking the adjusting component two as an example, the sliding frame 442 slides to the left, and the wedge block 441 thereon moves and separates from the inclined surface of the wedge groove 443. At this time, the fixing member 43 can move up and down freely within a certain range, thereby releasing the clamping force applied by the fixing member 43 to the corresponding sliding seat 41, and the sliding frame 442 moves to the right, and the wedge block 441 gradually wedges with the wedge groove 443, so that the fixing member 43 moves toward the sliding seat 41 and presses against it. The control process of the control member 44 in the adjusting component two is the same. Therefore, it is only necessary to control the sliding frame 442 to slide left and right to control the pressing state of the fixing member 43.

[0033] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , an adjusting member 45 is threadedly connected to the sliding frame 442, and the control unit 5 includes a control component 1 for controlling the rotation of two adjusting screws 42 in the same adjusting unit 4, a control component 2 for controlling the rotation of two adjusting members 45 in the same adjusting unit 4, and a third mounting seat 53 for mounting the control component 1 and the control component 2. The control component 1 and the control component 2 both include a moving seat 52 provided with a rack 51, and the moving seat 52 is slidably mounted on the third mounting seat 53 forward and backward, and the number of racks 51 on the moving seat 52 is two. The left ends of the adjusting screw 42 and the adjusting member 45 are fixedly mounted with gears. Taking the control component 1 as an example, one of the racks 51 is meshed with the gear on the adjusting screw 42 in the adjusting component 2 (such as Figure 3 As shown), the rack 51 is located below the adjusting screw 42, and the other rack 51 is meshed with the gear at the end of the adjusting screw 42 in the adjusting assembly (as shown Figure 4 As shown), and the rack 51 is located above the adjusting screw 42, the movable seat 52 moves forward and backward to synchronously control the rotation of the two adjusting screws 42, and the same applies to the control component 2.

[0034] participate Figure 1 , Figure 2 , Figure 7 , Figure 8 , Fig. 9 and Fig.10The connecting unit 6 includes a connecting piece 62 with connecting ends 61 detachably connected at both ends. There are two connecting pieces 62 in one connecting unit 6, one of which is located between the moving seats 52 in the front and rear adjacent control components 1 and is used to fix the two front and rear moving seats 52 together, and the other connecting piece 62 is located between the moving seats 52 in the front and rear adjacent control components 2 and is used to fix the two front and rear moving seats 52 together. The connecting ends 61 at both ends of the connecting piece 62 are fixedly installed on the corresponding moving seats 52 respectively. When the return unit, the adjustment unit 4 and the control unit 5 are installed according to the preset positions, the connecting piece 62 is uniformly installed between the corresponding connecting ends 61 to form a control system that is easy to uniformly operate. During the adjustment process, it is only necessary to control the movement of the adjacent moving seats 52 from the front end or the rear end to synchronously control the movement of the moving seats 52 fixedly connected together for synchronous adjustment, and a unified control rod is threadedly connected to any one of the moving seats 52 at the front end or the rear end, and the unified control rod is rotatably installed on the frame 7. By rotating the unified control rod, the movement of the moving seat 52 can be controlled and the moving seat 52 can be instantly locked in the current position. Correspondingly, the corresponding sliding seat 41 can be instantly locked in the current position through the rack 51. Combined with the self-locking function of the adjustment screw 42 and the sliding seat 41 during the adjustment process, the overall structure has a high stability, and the limiting reinforcement of the sliding seat 41 by the stabilizing member 43 fully ensures the stability of the overall structure.

[0035] See also Figure 1 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 Taking the connecting piece 62 that fixes the moving seat 52 in the front and rear adjacent control components 1 as an example, the connecting piece 62 includes a rod body 621, the front end of the rod body 621 is fixedly connected to the limiting block 1 622, the rear end of the rod body 621 is slidably connected to the limiting block 2 623, the limiting block 2 623 and the limiting block 1 622 are both provided with an annular limiting slot 624, and the rear end of the rod body 621 is threadedly connected with a fastener 625, the fastener 625 is a fastening nut and the fastener 625 is located at the rear side of the limiting block 2 623, and the connecting end 61 includes a placement groove The connecting seat 612 of 611, the placement groove 611 is U-shaped, the connecting seat 612 is fixedly installed on the corresponding moving seat 52 and has an L-shaped structure, and a limit plug 613 with an arc structure is fixedly provided on the connecting seat 612. When the return unit, the adjustment unit 4 and the control unit 5 are all installed according to the preset position, it is only necessary to place the two ends of the rod body 621 from top to bottom in the placement groove 611 of the corresponding connecting seat 612, and then tighten the fastener 625 to fix the corresponding two connecting seats 612 together, which is very convenient and fast.
