Description

Technical Field

[0001] The invention relates to the field of chain bucket conveyors, and in particular to an anti-reversal device for chain bucket conveyors. Background Art

[0002] Bucket chain conveyor, also known as trough conveyor, is a device that uses a bucket running along a track to transport materials horizontally or obliquely. It is widely used in power stations, mines, coal and other industries to transport various loose materials.

[0003] The chain bucket conveyor is controlled by a motor. In the event of a sudden power outage, the motor may not be able to control the rotation of the gears, and reversal will occur. Moreover, after long-term use of the device, the device will wear out and reversal will also occur. After reversal, the materials on the chain bucket conveyor will spill, seriously endangering the personal safety of the workers.

[0004] Therefore, it is necessary to provide a new anti-reversal device for chain bucket conveyor to solve the above technical problems. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an anti-reversal device for a chain bucket conveyor.

[0006] The anti-reversal device of the chain bucket conveyor provided by the present invention comprises: Conveyor chains, with material frames for conveying materials fixedly installed equidistantly between two conveyor chains; Also includes: A fixed frame, the fixed frame is installed in the middle between the two conveyor chains; The deceleration structure is installed between the bottom of the material frame and the fixed frame. The deceleration structure is used to decelerate the material frame after the conveying chain is reversed; Positioning mechanism: The positioning mechanism is installed between the deceleration structure and the fixed frame, and is used to position the material frame after the conveying chain is reversed. The deceleration structure and the positioning mechanism are installed in coordination, and are used to first decelerate and then fix the material frame. When the device is in use, the conveying chain on the bucket chain conveyor is in the conveying device, which will also drive the material frame to move. When the bucket chain conveyor loses power and reverses, the deceleration structure will decelerate the material frame that is transported in the reverse direction due to the reversal, and at the same time, it will synchronously drive the positioning mechanism to move, thereby fixing the position of the material frame that is transported in the reverse direction due to the reversal, so as to prevent the bucket chain conveyor from reversing.

[0007] Preferably, the deceleration structure includes a first sliding hole, a first sliding column, a deceleration plate, a return spring, a triangular block and a deceleration slope. The top of the fixed frame is symmetrically provided with a first sliding hole, the first sliding column is slidably installed inside the first sliding hole, the top of the two first sliding columns is fixedly provided with a deceleration plate, the bottom outer side of the first sliding column is sleeved with a return spring, one end of the return spring is fixedly connected to the top inner wall of the fixed frame, and the other end of the return spring is fixedly connected to the bottom of the first sliding column, a triangular block is fixedly installed in the middle of the lower surface of the material frame, a deceleration slope is provided on one side of the deceleration plate, and the deceleration slope is extruded with the triangular block. When the chain bucket conveyor is reversed due to power failure, the material frame will be transported in the reverse direction, and the triangular block on the material frame will squeeze the deceleration slope on the deceleration plate, thereby driving the first sliding column to slide and descend inside the first sliding hole, and the return spring will be in an elongated state at this time, so the descending effect of the deceleration plate will be reduced by the return effect of the return spring, that is, the extrusion force of the triangular block on the deceleration plate is buffered, and the reverse conveying speed of the material frame is slowed down.

[0008] Preferably, the deceleration slope has the same inclination angle as the triangular block. When the material frame is transported in the reverse direction, the triangular block on the material frame is ensured to stably squeeze the deceleration plate.

[0009] Preferably, the other side of the deceleration plate away from the deceleration slope is provided with an extrusion slope, and the extrusion slope is extruded with the triangular block. When the material frame is normally conveyed, the triangular block will squeeze the extrusion slope to lower the fixed block for normal conveyance of the material frame.

[0010] Preferably, the first sliding hole and the first sliding post slide in close contact with each other, so as to achieve stable sliding of the first sliding post in the first sliding hole.

[0011] Preferably, the positioning mechanism comprises a second sliding hole, a second sliding post, a fixing block, a triangular clamping block, a triangular clamping groove, a transmission rod, a mounting bracket, a limiting rod, a limiting hole, a positioning rod and a positioning hole, the top of the fixing bracket is symmetrically provided with a second sliding hole at a position close to the first sliding hole, the second sliding post is slidably installed inside the second sliding hole, the tops of the two second sliding posts are fixedly installed with a fixing block, one side of the fixing block is fixedly installed with a triangular clamping block, the triangular clamping groove is provided on one side of the fixing block, the triangular clamping groove is clamped with the triangular clamping block, the bottom of the first sliding post is rotatably installed with the transmission rod through an axle pin, the top inner wall of the fixing bracket is fixedly installed with the mounting bracket corresponding to the position between the first sliding post and the second sliding post, the bottom of the mounting bracket is fixedly installed with a limiting rod, the middle of the transmission rod is provided with a limiting hole, the limiting hole is slidably connected with the limiting rod, the bottom of the second sliding post is fixedly installed with a positioning rod, and one end of the transmission rod away from the first sliding post is provided with a positioning hole, and the positioning hole is slidably connected with the positioning rod. After slowing down the reverse conveying speed of the material frame, one end of the transmission rod at the bottom of the first slide column will be driven to descend, and then the limit rod will be driven to slide inside the limit hole, and the positioning rod will also be driven to slide inside the positioning hole. Therefore, the transmission will drive the second slide column to slide up inside the second slide hole. After the bottom of the triangular block exceeds the speed reducer, the reset effect of the reset spring is slowly restored. At this time, the triangular clamping block on one side of the fixed block will be stuck in the triangular clamping groove at the bottom of the material frame being conveyed in the reverse direction, which is used to control the reverse conveying of the material frame and prevent the chain bucket conveyor from reversing.

[0012] Preferably, the limiting hole and the limiting rod slide tightly together to achieve stable sliding of the limiting rod inside the limiting hole.

[0013] Preferably, the positioning hole and the positioning rod fit tightly and slide smoothly, so that the positioning rod can slide stably inside the positioning hole.

[0014] Compared with the prior art, the anti-reversal device of the chain bucket conveyor provided by the present invention has the following beneficial effects: The present invention provides an anti-reversal device for a chain bucket conveyor. When the chain bucket conveyor reverses due to power failure, the deceleration structure will decelerate the material frame that is reversely transported due to the reversal, and at the same time, it will synchronously drive the positioning mechanism to operate. After the bottom of the triangular block exceeds the deceleration plate, the resetting effect of the resetting spring is slowly restored. At this time, the triangular clamping block on one side of the fixed block will be clamped in the triangular clamping groove at the bottom of the material frame that is reversely transported, so as to control the reverse transport of the material frame and prevent the chain bucket conveyor from reversing.

DETAILED DESCRIPTION

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0019] See also Figures 1 to 4 , an embodiment of the present invention provides an anti-reversal device for a chain bucket conveyor, the anti-reversal device for the chain bucket conveyor comprising: Conveyor chains 1, with material frames 2 for conveying materials fixedly installed equidistantly between two conveyor chains 1; Also includes: A fixed frame 3, wherein the fixed frame 3 is installed in the middle between the two conveyor chains 1; The deceleration structure 4 is installed between the bottom of the material frame 2 and the fixing frame 3. The deceleration structure 4 is used to decelerate the material frame 2 after the conveying chain 1 is reversed; Positioning mechanism 5, the positioning mechanism 5 is installed between the deceleration structure 4 and the fixing frame 3, and is used to position the material frame 2 after the conveying chain 1 is reversed. The deceleration structure 4 and the positioning mechanism 5 are installed in coordination, and are used to first decelerate and then fix the material frame 2. When the device is in use, the conveying chain 1 on the bucket chain conveyor is in the conveying device, which will also drive the material frame 2 to move. When the bucket chain conveyor is powered off and reversed, the deceleration structure 4 will decelerate the material frame 2 that is reversely transported due to the reversal, and at the same time, it will synchronously drive the positioning mechanism 5 to move, and then fix the position of the material frame 2 that is reversely transported due to the reversal, so as to prevent the bucket chain conveyor from reversing.

[0020] See also Figures 1 to 4The deceleration structure 4 includes a first sliding hole 41, a first sliding column 42, a deceleration plate 43, a return spring 44, a triangular block 45 and a deceleration slope 46. The top of the fixed frame 3 is symmetrically provided with a first sliding hole 41, and the first sliding column 42 is slidably installed inside the first sliding hole 41. The deceleration plate 43 is fixedly installed on the top of the two first sliding columns 42. The bottom outer side of the first sliding column 42 is sleeved with a return spring 44, one end of the return spring 44 is fixedly connected to the top inner wall of the fixed frame 3, and the other end of the return spring 44 is fixedly connected to the bottom of the first sliding column 42. A triangular block 45 is fixedly installed in the middle of the lower surface of the material frame 2, and a deceleration slope 46 is opened on one side of the deceleration plate 43. The deceleration slope 46 and the triangular block 45 are extruded. When the chain bucket conveyor loses power and reverses, the material frame 2 will be transported in the reverse direction, and the triangular block 45 on the material frame 2 will squeeze the deceleration slope 46 on the deceleration plate 43, thereby driving the first slide column 42 to slide down inside the first slide hole 41. At this time, the return spring 44 will be in an elongated state, so the return effect of the return spring 44 will reduce the descending effect of the deceleration plate 43, that is, the extrusion force of the buffer triangular block 45 on the deceleration plate 43 will be reduced, thereby slowing down the reverse conveying speed of the material frame 2.

[0021] See also Figures 1 to 4 The deceleration slope 46 has the same inclination angle as the triangular block 45. When the material frame 2 is conveyed in the reverse direction, the triangular block 45 on the material frame 2 is ensured to stably squeeze the deceleration plate 43.

[0022] See also Figures 1 to 4 The other side of the deceleration plate 43 away from the deceleration slope 46 is provided with an extrusion slope 6, which is extruded with the triangular block 45. When the material frame 2 is normally conveyed, the triangular block 45 will squeeze the extrusion slope 6 to lower the fixed block 53 for normal conveyance of the material frame 2.

[0023] See also Figures 1 to 4 The first sliding hole 41 and the first sliding column 42 slide closely together, so that the first sliding column 42 can slide stably inside the first sliding hole 41 .

[0024] See also Figures 1 to 4The positioning mechanism 5 includes a second sliding hole 51, a second sliding column 52, a fixing block 53, a triangular block 54, a triangular slot 55, a transmission rod 56, a mounting frame 57, a limiting rod 58, a limiting hole 59, a positioning rod 510 and a positioning hole 511. The top of the fixing frame 3 is symmetrically provided with a second sliding hole 51 near the first sliding hole 41. The second sliding column 52 is slidably installed inside the second sliding hole 51. The top of the two second sliding columns 52 is fixedly installed with a fixing block 53. A triangular block 54 is fixedly installed on one side of the fixing block 53. A triangular slot 55 is provided on one side of the triangular block 45. The triangular slot 55 is engaged with the triangular block 54, and a transmission rod 56 is rotatably installed at the bottom of the first slide post 42 through an axle pin. A mounting frame 57 is fixedly installed on the top inner wall of the fixing frame 3 corresponding to the position between the first slide post 42 and the second slide post 52. A limiting rod 58 is fixedly installed at the bottom of the mounting frame 57. A limiting hole 59 is provided in the middle of the transmission rod 56, and the limiting hole 59 is slidably connected to the limiting rod 58. A positioning rod 510 is fixedly installed at the bottom of the second slide post 52, and a positioning hole 511 is provided at one end of the transmission rod 56 away from the first slide post 42, and the positioning hole 511 is slidably connected to the positioning rod 510. After slowing down the reverse conveying speed of the material frame 2, one end of the transmission rod 56 at the bottom of the first slide post 42 will be driven to descend, and then the limiting rod 58 will be driven to slide inside the limiting hole 59, and the positioning rod 510 will also be driven to slide inside the positioning hole 511. Therefore, the transmission will drive the second slide post 52 to slide up inside the second slide hole 51. After the bottom of the triangular block 45 exceeds the speed reducer 43, the reset effect of the reset spring 44 is slowly restored. At this time, the triangular clamping block 54 on one side of the fixed block 53 will be stuck in the triangular clamping groove 55 at the bottom of the material frame 2 being conveyed in the reverse direction, so as to control the reverse conveying of the material frame 2 and prevent the chain bucket conveyor from reversing.

[0025] See also Figures 1 to 4 The limiting hole 59 and the limiting rod 58 are tightly fitted and slidable, so that the limiting rod 58 can slide stably inside the limiting hole 59.

[0026] See also Figures 1 to 4 The positioning hole 511 and the positioning rod 510 fit tightly and slide smoothly, so that the positioning rod 510 can slide stably inside the positioning hole 511.

[0027] When the device is in use, the conveying chain 1 on the chain bucket conveyor is in the conveying device, which will drive the material frame 2 to move. When the chain bucket conveyor is powered off and reversed, the material frame 2 will be transported in the reverse direction, and the triangular block 45 on the material frame 2 will squeeze the deceleration slope 46 on the deceleration plate 43, thereby driving the first slide post 42 to slide down inside the first slide hole 41. At this time, the return spring 44 will be in an elongated state, so the descending effect of the deceleration plate 43 will be reduced by the return effect of the return spring 44, that is, the squeezing force of the buffer triangular block 45 on the deceleration plate 43 will be reduced, thereby slowing down the reverse conveying speed of the material frame 2. During the process, one end of the transmission rod 56 at the bottom of the first slide post 42 will be driven to descend, and then the limiting rod 58 will be driven to slide inside the limiting hole 59, and the positioning rod 510 will also be driven to slide inside the positioning hole 511, so the transmission will drive the second slide post 52 to slide and rise inside the second slide hole 51. After the bottom of the triangular block 45 exceeds the deceleration plate 43, the reset effect of the reset spring 44 is slowly restored. At this time, the triangular clamping block 54 on one side of the fixed block 53 will be stuck in the triangular clamping groove 55 at the bottom of the material frame 2 for reverse conveying, so as to control the reverse conveying of the material frame 2 and prevent the chain bucket conveyor from reversing.
