Technical Field

[0001] The utility model belongs to the technical field of gangue conveying equipment, and in particular relates to a belt gangue anti-rolling device. Background Art

[0002] During the underground tunnel transportation process, due to the large slope of some tunnels, the gangue is easily caused to roll off the belt during the belt transportation process, causing personal injury or damage to equipment. Especially during the operation of the belt, in order to ensure the safety of personnel, the rolling gangue cannot be cleaned up at any time, causing the rolling gangue to accumulate on the belt, which is easy to cause belt wear. At present, a baffle is usually hingedly installed above the belt. The baffle is prone to cracking and damage during long-term use and needs to be replaced. During replacement, sometimes a large amount of gangue is squeezed on the baffle. The gangue on site needs to be transported and removed before the baffle can be pulled out, which causes high labor intensity for on-site maintenance personnel and is not convenient for the later maintenance and repair of the anti-rolling gangue device.

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Please refer to Figure 1 and Figure 2 simultaneously. Now, the belt anti-rolling gangue device provided by the present utility model will be described. The belt anti-rolling gangue device includes a fixing frame 1, a support frame 2, a pushing member 3 and a baffle 4. The fixing frame 1 is detachably installed on the belt conveyor frame 6, and two vertical rods 11 installed on both sides of the belt are fixedly installed on the fixing frame 1; the support frame 2 is installed on the fixing frame 1, and the support frame 2 includes two support rods 21 slidably arranged inside the vertical rods 11; the pushing member 3 is installed between the vertical rods 11 and the support rods 21 for pushing the support rods 21 to slide inside the vertical rods 11; the baffle 4 is hinged to one side of the support frame 2, and protruding portions 41 for being attached to the support frame 2 are arranged at both sides of the baffle 4.

[0025] Compared with the prior art, the belt anti-rolling gangue device provided in this embodiment is provided with a fixing frame 1, and the fixing frame 1 is used to be installed on the belt conveyor frame 6, and the belt conveyor frame 6 is a mounting frame for the belt used to transport gangue. The bottom end of the fixing frame 1 can be detachably installed on the belt conveyor frame 6, and two vertical poles 11 are fixedly installed on the fixing frame 1, and the belt for conveying gangue is located between the two vertical poles 11. A support rod 21 is slidably provided at the top of the vertical pole 11. In the free state, the support rod 21 is located inside the vertical pole 11, and the lower end of the support rod 21 abuts against the vertical pole 11. A baffle 4 is hingedly provided on the support frame 2, and the two side edges of the baffle 4 are protrudingly provided with protrusions 41 for abutting against the support frame 2. The pushing member 3 is a hydraulic cylinder. When the baffle 4 needs to be replaced on site, a set of anti-rolling gangue device can be added behind the fixed frame 1 where the baffle 4 needs to be replaced, and then the supporting frame 2 is lifted up by the pushing member 3, so that the baffle 4 can be pulled out from the inside of the gangue. When the pulled out gangue rolls backward, it will be blocked by the baffle 4 at the rear to prevent the gangue from continuing to fall. Then the fixed frame 1 and the supporting frame 2 are removed as a whole from the belt conveyor frame 6 to replace the baffle 4. When replacing the baffle 4, there is no need for personnel to carry the gangue, the operation is simple, and it is convenient for the later maintenance and repair of the anti-rolling gangue device.

[0026] Specifically, in this embodiment, the pusher 3 drives the support frame 2 to move upward, so that the support frame 2 drives the baffle plate 4 to move upward and pulls the baffle plate 4 out from the inside of the gangue.

[0027] In some embodiments, the vertical pole 11 can be used as follows: Figure 1 See the structure shown. Figure 1 , the outer side of the vertical rod 11 is an open structure, and the bottom end of the support rod 21 is provided with a mounting groove for accommodating the pusher 3, and the side wall of the mounting groove is provided with a clearance for avoiding the pusher 3 from being installed from the outer side of the vertical rod 11 to the inside of the mounting groove. The side opposite to the two vertical rods 11 is an open structure. A clearance is provided on the same side of the support rod 21 as the vertical rod 11, so that the pusher 3 can be placed into the inside of the mounting groove through the outer side of the vertical rod 11. When the baffle 4 needs to be replaced, the pusher 3 can be placed into the inside of the mounting groove in the support rod 21 through the outer side of the vertical rod 11. The fixed end of the pusher 3 abuts against the vertical rod 11, and the driving end of the pusher 3 abuts against the top of the mounting groove on the support rod 21. Thereby, the pusher can push the support rod 21 out from the inside of the vertical rod 11. When the baffle 4 is pulled out from the gangue, the pusher 3 is depressurized and can be taken out from the support rod 21 for separate storage. The pusher 3 can be temporarily installed when the baffle 4 needs to be replaced.

[0028] In some embodiments, the baffle 4 may be formed as follows: Figure 1 See the structure shown. Figure 1, one side of the baffle 4 is detachably installed with a flexible plate 42 for abutting against the belt, and the flexible plate 42 extends downward on the baffle 4. The flexible plate 42 is a part processed from rubber material. The flexible plate is fixedly installed on the baffle 4 by bolts and extends outward from the baffle 4. When the gangue conveying belt is in working state, the flexible plate 42 abuts against the belt, which can reduce the wear of the conveying belt. At the same time, when the gangue falls onto the flexible plate 42, the flexible plate deforms according to its own elastic characteristics, and when the gangue detaches from the flexible plate 42, the flexible plate 42 can automatically return to its original state, improving the service life.

[0029] Specifically, in this embodiment, the flexible plate 42 can be directly replaced in the later stage, without disassembling and replacing the entire baffle 4.

[0030] In some embodiments, the above-mentioned fixing frame 1 can adopt the structure as Figure 2 shown. Refer to Figure 2 , a stop rod 5 for supporting the flexible plate 42 is fixedly installed on the fixing frame 1. When the baffle 4 is flipped towards the direction close to the support frame 2, the flexible plate 42 can abut against the stop rod 5 to support the flexible plate 42, avoiding excessive deformation of the flexible plate 42 and causing the gangue to pass through the bottom of the support frame 2, and improving the stability of the flexible plate 42 in intercepting the gangue.

[0031] In some embodiments, the above-mentioned stop rod 5 can adopt the structure as Figure 1 shown. Refer to Figure 1 , the number of the stop rods 5 is two, and the two stop rods 5 are respectively fixedly installed on the two vertical rods 11, and a clearance for the gangue to pass through is arranged between the two stop rods 5. The number of the stop rods 5 is two, and the two stop rods 5 are respectively fixedly installed on the vertical rods 11, and one end of the stop rod 5 is fixedly installed on the vertical rod 11, and the other end extends into the fixing frame 1. There is a clearance between the two baffles 4 for the gangue to pass through the fixing frame 1 along the conveying direction of the belt, avoiding affecting the conveying of the gangue. At the same time, it can play a certain role in supporting and limiting the flexible plate 42.

[0032] In some embodiments, the above-mentioned vertical rod 11 can adopt the structure as Figure 1 , Figure 2 shown. Refer to Figure 1 , Figure 2The bottom of the vertical pole 11 is fixedly mounted with a fixing plate 111 for fixing to the belt conveyor frame 6, and the fixing frame 1 includes a fixing assembly 7 for fixing the fixing plate 111 to the belt conveyor frame 6. The fixing plate 111 is overlapped on the top surface of the belt conveyor frame 6, and the bottom end of the vertical pole 11 is fixedly mounted in the middle of the fixing plate 111, which can play a certain oblique supporting role on the vertical pole 11 to prevent the vertical pole 11 from tilting on the belt conveyor frame 6. At the same time, the fixing assembly 7 is used to fix the two ends of the fixing plate 111 on the belt conveyor frame 6, thereby realizing the connection between the vertical pole 11 and the belt conveyor frame 6.

[0033] In some embodiments, the fixing assembly 7 may be configured as follows: Figure 1 , Figure 2 See also Figure 1 , Figure 2 The fixing assembly 7 includes a U-shaped member 71 and a tensioning member 72. The U-shaped member 71 includes a pressure plate 711 and a support plate 712 which are arranged in parallel at intervals, and a connecting plate 713 connected between the pressure plate 711 and the support plate 712. The pressure plate 711 is used to press the fixing plate 111 onto the belt conveyor frame 6; the tensioning member 72 is threadedly connected to the support plate 712, and one end of the tensioning member 72 is used to abut against the bottom of the belt conveyor frame 6. The U-shaped member 71 is formed in one piece. When fixing the fixing plate 111, the pressure plate 711 is placed on the top surface of the fixing plate 111, and a gap for avoiding the vertical pole 11 is provided in the middle of the pressure plate 711. The connecting plate 713 is located on the outside of the belt conveyor frame 6, the support plate 712 is located at the bottom of the belt conveyor frame 6, and the support plate 712 is spaced apart from the belt conveyor frame 6. A nut threadedly connected to the jacking member 72 is fixedly installed at the bottom of the support plate 712. The jacking member 72 is a bolt threadedly connected to the nut and penetrates the support plate 712. The jacking member 72 is rotated so that the end of the jacking member 72 abuts against the bottom of the belt conveyor frame 6, thereby pressing the fixed plate 111 against the belt conveyor frame 6.

[0034] Specifically, in this embodiment, the belt conveyor frame 6 is a bracket for installing the belt, and two longitudinal beams are arranged along the belt conveying direction in the length direction on the bracket, and the fixing plate 111 is installed on the longitudinal beams through the fixing assembly 7.

[0035] In some embodiments, the U-shaped member 71 may be formed as follows: Figure 2 See the structure shown. Figure 2 The side edge of the pressing plate 711 away from the connecting plate 713 is bent toward the side close to the supporting plate 712 to provide a limiting plate 714. The limiting plate 714 and the connecting plate 713 form a gap for installing the longitudinal beam on the belt conveyor frame 6. When installing the U-shaped member 71, the longitudinal beam can be slid between the limiting plate 714 and the connecting plate 713, which plays a certain role in limiting the fixing plate 111 and ensuring the stability of the fixing plate 111 installation.

[0036] Specifically, in this embodiment, the position of the fixing plate 111 along the longitudinal direction of the longitudinal beam is limited by the pressing plate 711 and the vertical rod 11, and the position of the fixing plate 111 along the direction perpendicular to the longitudinal direction of the longitudinal beam is limited by the limiting plate 714 and the connecting plate 713, so as to further ensure the stability of the installation position of the vertical rod 11.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
