Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining equipment technology, and in particular to a device for preventing coal from falling. Background Technology
[0002] Belt conveyors are an essential piece of equipment in underground coal mines, used to transport mined coal to designated storage points. During the process of feeding coal at a large angle, coal can easily fall off the belt due to belt vibration, requiring manual labor to pick up the fallen coal.
[0003] The prior art CN217837135U discloses a coal mine inclined belt conveyor anti-coal-falling device, which includes a main component and a baffle component. The main component consists of a support plate, a connecting plate, a short suspension rod, a middle suspension rod, a long suspension rod, a mounting plate, a limiting groove, and a connecting groove. The baffle component consists of a rubber baffle, a counterweight plate, and a limiting block. The connecting plate, the rubber baffle, and the support plate cooperate with each other to form a protective cover to baffle the belt and prevent the coal transported on the belt from falling off due to vibration. The counterweight block, in conjunction with the rubber baffle, can increase the weight of the rubber baffle, stabilize the rubber baffle, and prevent it from moving arbitrarily due to collisions with transported coal, thus preventing a large gap from forming between the rubber baffle and the belt and causing coal to fall off.
[0004] However, in the above structure, when the inclination angle of the belt conveyor is large, the coal may slide down due to gravity during the conveying process, which may cause the coal to jump and thus damage the coal. In severe cases, it may even affect the normal use of the belt conveyor. Utility Model Content
[0005] The purpose of this utility model is to provide a coal-falling prevention device, which solves the problem that when the inclination angle of the belt conveyor is large, the coal may fall due to gravity during the conveying process, which may cause the coal to jump and thus damage the coal, and in severe cases, even affect the normal use of the belt conveyor.
[0006] To achieve the above objectives, this utility model provides a coal-fall prevention device, comprising a connecting plate, two support plates, two rubber baffles, and multiple buffer mechanisms. The two support plates are respectively disposed on both sides of the connecting plate, and the two rubber baffles are slidably connected to the two support plates and respectively located below the two support plates. The multiple buffer mechanisms are respectively disposed below the connecting plate. Each buffer mechanism includes two fixed blocks, a connecting shaft, a connecting block, a buffer plate, a guide plate, and a support assembly. The two fixed blocks are disposed opposite each other below the connecting plate, the connecting shaft is fixedly connected between the two fixed blocks, the connecting block is rotatably disposed on the outer side wall of the connecting shaft, one end of the buffer plate is fixedly connected to the connecting block, the guide plate is fixedly connected to the other end of the buffer plate, and the support assembly is disposed on one side of the buffer plate.
[0007] The support assembly includes a fixed plate, a mounting plate, two telescopic rods, two springs, and a mounting component. The fixed plate is fixedly connected to the buffer plate. The mounting plate is located on the side of the fixed plate away from the buffer plate. The two telescopic rods are fixedly connected between the fixed plate and the mounting plate. The two springs are respectively sleeved on the outer side walls of the two telescopic rods. The mounting component is located below the connecting plate.
[0008] The mounting component includes a mounting column and a support plate. The mounting column is fixedly connected to the connection plate and is located below the connection plate. The support plate is fixedly connected between the mounting column and the mounting plate.
[0009] The anti-coal-fall device also includes a reinforcement mechanism, which is disposed between the receiving plate and the mounting plate.
[0010] The reinforcement mechanism includes a mounting base, a fixing base, and a reinforcing rod. The mounting base is fixedly connected to the receiving plate and is located below the receiving plate. The fixing base is fixedly connected to the mounting plate and is located on the side of the mounting plate away from the fixing plate. The reinforcing rod is disposed between the mounting base and the fixing base.
[0011] This utility model discloses a coal-falling prevention device. When jumping coal falls onto the buffer plate, the buffer plate rotates under the impact force of the coal. The support component buffers the impact force, preventing the coal from directly impacting the conveyor belt and causing damage. After the impact, the coal slides back onto the conveyor belt under its own weight along the buffer plate and the guide plate, and moves with the conveyor belt to the designated storage point. This solves the problem that when the inclination angle of the conveyor belt is large, the coal may slide down due to gravity during the conveying process, which may cause the coal to jump and be damaged, or even affect the normal use of the conveyor belt.

Detailed Implementation
[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0019] First Embodiment
[0020] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the first embodiment of this utility model. Figure 2 This is a structural schematic diagram of the buffer plate, guide plate, mounting column and receiving plate of the first embodiment of this utility model. Figure 3 This is a schematic diagram of the buffer mechanism of the first embodiment of the present invention.
[0021] This utility model provides a coal-fall prevention device, including a connecting plate 101, two support plates 102, two rubber baffles 103, and multiple buffer mechanisms. The buffer mechanism includes two fixing blocks 104, a connecting shaft 105, a connecting block 106, a buffer plate 107, a guide plate 108, and a support assembly. The support assembly includes a fixing plate 109, a mounting plate 110, two telescopic rods 111, two springs 112, and a mounting component. The mounting component includes a mounting column 113 and a receiving plate 114. The above structure solves the problem that when the belt conveyor has a large inclination angle, the coal may slide down due to gravity during the conveying process, which may cause the coal to jump and be damaged. In severe cases, it may even affect the normal use of the belt conveyor.
[0022] In a specific implementation, two support plates 102 are respectively disposed on both sides of the connecting plate 101, and two rubber baffles 103 are slidably connected to the two support plates 102 and are respectively located below the two support plates 102. The support plates 102, the connecting plate 101 and the rubber baffles 103 cooperate with each other to prevent coal from falling from both sides of the conveyor belt during transportation.
[0023] Multiple buffer mechanisms are respectively disposed below the connecting plate 101. Two fixing blocks 104 are disposed opposite each other below the connecting plate 101. The connecting shaft 105 is fixedly connected between the two fixing blocks 104. The connecting block 106 is rotatably disposed on the outer side wall of the connecting shaft 105. One end of the buffer plate 107 is fixedly connected to the connecting block 106. The guide plate 108 is fixedly connected to the other end of the buffer plate 107. The support assembly is disposed on one side of the buffer plate 107. The buffer mechanism is used to block coal that jumps during the descent. The fixing block 104 is used to install the connecting shaft 105. 106 is used to connect the buffer plate 107 and the mounting shaft. When the jumping coal falls onto the buffer plate 107, the buffer plate 107 rotates under the impact force of the coal. The support component buffers the impact force, preventing the coal from directly hitting the belt conveyor and causing damage to the belt conveyor. After the impact, the coal slides back onto the belt conveyor along the buffer plate 107 and the guide plate 108 under its own weight, and moves with the belt conveyor to the designated storage point. This solves the problem that when the inclination angle of the belt conveyor is large, the coal may slide down due to gravity during the conveying process, which may cause the coal to jump and thus cause damage to the coal. In severe cases, it may even affect the normal use of the belt conveyor.
[0024] The fixed plate 109 is fixedly connected to the buffer plate 107. The mounting plate 110 is disposed on the side of the fixed plate 109 away from the buffer plate 107. The two telescopic rods 111 are fixedly connected between the fixed plate 109 and the mounting plate 110. The two springs 112 are respectively sleeved on the outer side walls of the two telescopic rods 111. The mounting component is disposed below the connecting plate 101. The fixed plate 109 and the mounting plate 110 are used to install the telescopic rods 111. The mounting component is used to connect the mounting plate 110. When the jumping coal hits the buffer plate 107, the telescopic rods 111 and the springs 112 retract to buffer the impact force. At the same time, the coal that has lost speed slides back onto the belt conveyor along the buffer plate 107 and the guide plate 108 under its own gravity.
[0025] The mounting post 113 is fixedly connected to the connecting plate 101 and is located below the connecting plate 101. The receiving plate 114 is fixedly connected between the mounting post 113 and the mounting plate 110. The mounting post 113 is used to install the receiving plate 114, and the receiving plate 114 is used to support the mounting plate 110.
[0026] When using the anti-coal-falling device of this utility model, when the jumping coal falls onto the buffer plate 107, the buffer plate 107 rotates under the impact force of the coal. The telescopic rod 111 and the spring 112 retract to buffer the impact force, preventing the coal from directly hitting the conveyor belt and causing damage to it. After the impact, the coal slides back onto the conveyor belt under its own weight along the buffer plate 107 and the guide plate 108, and moves with the conveyor belt to the designated storage point. This solves the problem that when the inclination angle of the conveyor belt is large, the coal may slide down due to gravity during the conveying process, which may cause the coal to jump and be damaged, and in severe cases, even affect the normal use of the conveyor belt.

[0029] Based on the first embodiment, the present invention provides a coal-fall prevention device, which further includes a reinforcement mechanism, comprising a mounting base 201, a fixing base 202, and a reinforcing rod 203.
[0030] In a specific implementation, the reinforcement mechanism is disposed between the receiving plate 114 and the mounting plate 110. The reinforcement mechanism is used to enhance the overall strength of the buffer mechanism and ensure its stability during use.
[0031] The mounting base 201 is fixedly connected to the receiving plate 114 and located below the receiving plate 114. The fixing base 202 is fixedly connected to the mounting plate 110 and located on the side of the mounting plate 110 away from the fixing plate 109. The reinforcing rod 203 is disposed between the mounting base 201 and the fixing base 202. The mounting base 201 and the fixing base 202 are used to fix the reinforcing rod 203. According to the stability of triangles, the receiving plate 114, the mounting plate 110 and the reinforcing rod 203 form a triangle. The mounting base 201, the fixing base 202 and the reinforcing rod 203 cooperate with each other to support the mounting plate 110, thereby improving the overall strength of the buffer mechanism and ensuring stability during use.
