Description
Technical Field
[0001] This utility model relates to the field of coal mine transmission technology, and in particular to a transmission support roller for a coal preparation plant. Background Technology
[0002] Coal transportation in coal preparation plants is generally accomplished using belt conveyors. To improve the stability of the belt during operation, a series of idlers are usually installed under the belt for support, preventing the belt from tilting or even falling off.
[0003] In the prior art, a conveyor support roller for coal preparation plants disclosed in prior art patent application number CN202221749429.7 can be used to prevent the belt from falling off. The side roller assembly is driven to rotate around the hinge seat by the angle adjustment component, so that there is an inclination angle between the side roller assembly and the bottom roller assembly. The belt is laid on the surface of the bottom roller assembly and the side roller assembly, thereby forming a concave conveyor channel, making it difficult for coal to fall from both sides.
[0004] However, the above method requires rotating both threaded posts simultaneously for adjustment, resulting in low adjustment efficiency. Utility Model Content
[0005] The purpose of this utility model is to provide a transmission support roller for coal preparation plants, which aims to solve the technical problem that the adjustment efficiency is low because the existing technology requires simultaneous rotation of the threaded columns on both sides.
[0006] To achieve the above objectives, this utility model employs a conveyor support roller for a coal preparation plant, comprising a support frame, a flat roller, two side rollers, and an adjustment mechanism. The flat roller is mounted on the support frame. The adjustment mechanism includes a power assembly and two sets of adjustment components. Each adjustment component includes a sliding support unit, a force-bearing plate, multiple springs, a displacement plate, multiple insert rods, protrusions, connecting blocks, and a rotating unit. The support frame has two sliding grooves, two recesses, and multiple through holes. The two protrusions are slidably connected to their corresponding recesses. The rotating unit is rotatably connected to the support frame. The rotating unit is equipped with a corresponding side roller. The two ends of the connecting block are respectively hinged to the protrusion and the rotating unit. The protrusion has a slot. The two ends of the spring are respectively fixedly connected to the bracket and the displacement plate. One end of each of the multiple insertion rods is fixedly connected to the displacement plate. The other end of each of the multiple insertion rods passes through the corresponding through hole. The slot is adapted to the multiple insertion rods. The force plate is fixedly connected to the displacement plate. The sliding support unit is slidably connected to the slide groove. The power component is set on the bracket.
[0007] The power assembly includes a rotating rod and an elliptical plate. The rotating rod is rotatably connected to the bracket, and the elliptical plate is fixedly connected to the outer wall of the rotating rod. The outer wall of the elliptical plate is in contact with the two sliding abutment units.
[0008] The sliding support unit includes a slider, a follower plate, and a support component. The force-bearing plate has an inclined surface. The slider is slidably connected to the corresponding groove. The follower plate is fixedly connected to the slider. The support component is fixedly connected to the follower plate and is in contact with the inclined surface.
[0009] The supporting component includes a connecting plate and a supporting rod. The connecting plate is fixedly connected to the follower plate, and the supporting rod is fixedly connected to the connecting plate, and the supporting rod is in contact with the inclined surface.
[0010] The rotating unit includes a first support, a second support, and a circular shaft. The first support is rotatably connected to the bracket. The two ends of the circular shaft are fixedly connected to the first support and the second support, respectively. The circular shaft is connected to the corresponding side roller. The second support is hinged to the connecting block.
[0011] This utility model discloses a conveyor support roller for a coal preparation plant. In practical use, the flat roller and two side rollers support the belt, preventing it from tilting or even falling off. When the angle of the two side rollers needs to be adjusted, the power assembly drives two sliding abutment units to move relative to each other. The two sliding abutment units abut against two force plates, causing the two force plates to move downward. Simultaneously, the downward movement of the two force plates drives two displacement plates downward, which in turn drives multiple insertion rods downward, causing the insertion rods in the slots to move away from the slots. Then, two protrusions slide. As the protrusions slide, the angle of the side rollers can be adjusted through the connecting block. After adjustment, the power assembly is released, and the spring returns to its original position, causing the displacement plates to move upward, which in turn drives multiple insertion rods upward. The corresponding insertion rods are then inserted into the slots to limit the protrusions. This method solves the technical problem of low adjustment efficiency in the prior art, which requires simultaneous rotation of threaded columns on both sides for adjustment.

[0020] This utility model provides a transmission support roller for a coal preparation plant, including a bracket 101, a flat roller 102, two side rollers 103, and an adjustment mechanism. The adjustment mechanism includes a power component and two sets of adjustment components. Each adjustment component includes a sliding abutment unit, a force plate 104, multiple springs 105, a displacement plate 106, multiple insert rods 107, a protrusion 108, a connecting block 109, and a rotation unit. The power component includes a rotating rod 110 and an elliptical plate 111. The sliding abutment unit includes a slider 112, a follower plate 113, and an abutment component. The abutment component includes a connecting plate 114 and an abutment rod 115. The rotation unit includes a first support 116, a second support 117, and a round shaft 118. The aforementioned solution solves the technical problem in the prior art where adjustment requires simultaneous rotation of the threaded columns on both sides, resulting in low adjustment efficiency.
[0021] In this specific embodiment, the flat idler 102 is mounted on the bracket 101, and the belt is supported by the flat idler 102 and the two side idlers 103 to prevent the belt from tilting or even falling off.
[0022] The bracket 101 has two sliding grooves 119, two recesses 120, and multiple through holes 121. Two protrusions 108 are slidably connected to their corresponding recesses 120. The rotating unit is rotatably connected to the bracket 101 and is equipped with corresponding side rollers 103. The two ends of the connecting block 109 are hinged to the protrusions 108 and the rotating unit, respectively. The protrusions 108 have slots 122. The two ends of the spring 105 are fixed to the bracket 101 and the displacement plate 106, respectively. The system is fixedly connected, with one end of each of the multiple insertion rods 107 fixedly connected to the displacement plate 106, and the other end of each insertion rod 107 passing through the corresponding through hole 121. The slot 122 is adapted to the multiple insertion rods 107. The force plate 104 is fixedly connected to the displacement plate 106. The sliding support unit is slidably connected to the slide groove 119. The power assembly is mounted on the bracket 101. In actual use, the flat idler roller 102 and the two side idler rollers 103 support the belt to prevent it from slipping. If the two side rollers 103 tilt or even detach, and the angle of the two side rollers 103 needs to be adjusted, the power assembly drives the two sliding abutment units to move relative to each other. The two sliding abutment units abut against the two force plates 104, causing the two force plates 104 to move downward. Simultaneously, the downward movement of the two force plates 104 causes the two displacement plates 106 to move downward, which in turn causes the multiple insertion rods 107 to move downward, causing the insertion rods 107 in the slot 122 to move away from the slot 122. Then, the two side rollers 103 slide... When the protrusion 108 slides, the angle of the side roller 103 can be adjusted via the connecting block 109. After adjustment, the power assembly is released, and the spring 105 resets, thereby driving the displacement plate 106 to move upward, which in turn drives the multiple insertion rods 107 to move upward. The corresponding insertion rods 107 are inserted into the slot 122 to limit the protrusion 108. This method solves the technical problem of low adjustment efficiency caused by the need to rotate the threaded columns on both sides simultaneously for adjustment in the prior art.
[0023] Secondly, the rotating rod 110 is rotatably connected to the bracket 101, and the elliptical plate 111 is fixedly connected to the outer wall of the rotating rod 110. The outer walls of the elliptical plate 111 are in contact with both sliding abutment units. In actual use, by rotating the rotating rod 110, the rotating rod 110 drives the elliptical plate 111 to rotate, and the elliptical plate 111, in turn, drives the two sliding abutment units to move relative to each other.
[0024] Meanwhile, the force-bearing plate 104 has an inclined surface 123, the slider 112 is slidably connected to the corresponding groove 119, the follower plate 113 is fixedly connected to the slider 112, the abutting member is fixedly connected to the follower plate 113 and the abutting member contacts the inclined surface 123, the connecting plate 114 is fixedly connected to the follower plate 113, the abutting rod 115 is fixedly connected to the connecting plate 114 and the abutting rod 115 contacts the inclined surface 123. When the elliptical plate 111 rotates, it drives the follower plate 113 to move. The follower plate 113 drives the slider 112 to slide in the corresponding groove 119 and drives the connecting plate 114 to move. The connecting plate 114 drives the abutting rod 115 to slide on the inclined surface 123, thereby driving the force-bearing plate 104 to move downward.
[0025] In addition, the first support 116 is rotatably connected to the bracket 101, and the two ends of the round shaft 118 are fixedly connected to the first support 116 and the second support 117 respectively. The round shaft 118 is connected to the corresponding side roller 103. The second support 117 is hinged to the connecting block 109. When the connecting block 109 rotates, it drives the second support 117 to rotate. When the second support 117 rotates, it drives the first support 116 to rotate on the bracket 101 through the round shaft 118.
[0026] In a coal preparation plant, the conveyor support roller of this invention supports the belt using the flat roller 102 and two side rollers 103 to prevent the belt from tilting or even falling off. When the angle of the two side rollers 103 needs to be adjusted, the power assembly drives two sliding abutment units to move relative to each other. The two sliding abutment units abut against two force plates 104, causing the two force plates 104 to move downwards. Simultaneously, the downward movement of the two force plates 104 drives the two displacement plates 106 to move downwards, which in turn drives the multiple insertion rods 107 to move downwards. The insertion rod 107 in the slot 122 is moved away from the slot 122, and then the two protrusions 108 are slid. When the protrusions 108 slide, the angle of the side roller 103 can be adjusted through the connecting block 109. After the adjustment is completed, the power component is released. At this time, the spring 105 is reset and drives the displacement plate 106 to move upward, which in turn drives the multiple insertion rods 107 to move upward. The corresponding insertion rods 107 are inserted into the slot 122 to limit the protrusions 108. This method solves the technical problem of low adjustment efficiency caused by the need to rotate the threaded column on both sides at the same time in the prior art.
[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
