Description

Technical Field

[0001] The utility model relates to the technical field of transmission belts, in particular to a transportation transmission belt. Background Technique

[0002] The transmission belt is a common short-distance transportation tool. Compared with other transportation tools, it has the characteristics of simple setting, convenient operation and low maintenance cost. It can be set in the relatively complex working environment in the coal mine shaft. And compared with the traditional mine car transportation, the transmission belt does not need to lay tracks in advance, nor does it need to carry out frequent track maintenance in daily production, which greatly reduces the coal mining cost.

[0003] However, when the current transportation transmission belt is in use, the belt becomes longer under the pressure of the transported coal blocks, which is easy to cause the belt to loosen. Due to the too large transmission span, the existing tensioning mechanisms are basically arranged at both ends of the transmission belt, and the tensioning distance is relatively short. In view of the above problems, a transportation transmission belt is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a transportation transmission belt to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A transportation transmission belt includes a mounting frame. On both sides of one end of the mounting frame, first support frames are symmetrically and fixedly installed. A driven roller is rotatably installed between the first support frames through a pedestal bearing. On both sides of the other end of the mounting frame, second support frames are symmetrically and fixedly installed. A driving roller is rotatably installed between the second support frames through a pedestal bearing. A driving motor is fixedly installed on the top of one of the second support frames, and the output end of the driving motor is fixedly connected to the end of the driving roller. Support mechanisms are evenly and fixedly installed on the top of the mounting frame. A plurality of tensioning mechanisms are evenly arranged in the mounting frame. A conveyor belt is wound between the driven roller and the driving roller. The tensioning mechanisms are staggered and arranged on the upper and lower sides of the conveyor belt.

[0007] As a further scheme of the utility model: The tensioning mechanism includes a tensioning roller. Strip-shaped holes are opened in the columns of the mounting frame at both ends of the tensioning roller. The two ends of the tensioning roller are built in the corresponding strip-shaped holes. Nuts are threadedly connected to the ends of the tensioning roller outside the mounting frame. A connecting sleeve is sleeved outside the nut at the end of the tensioning roller. The bottom end of the connecting sleeve is rotatably connected to a screw rod. The screw rod is threadedly connected through a cross plate. The cross plate is fixedly installed on the side wall of the column of the mounting frame.

[0008] As a still further scheme of the utility model: A handle is fixedly connected to the bottom end of the screw rod.

[0009] As a further solution of the utility model: The support mechanism includes a bracket, which is fixedly installed on the top of the mounting frame by bolts. A first support roller is arranged inside the bracket. Connecting seats are fixedly installed at both ends of the first support roller by bolts, and the connecting seats are fixedly installed in the bracket by bolts. A second support roller is arranged between the side wall of the bracket and the connecting seat, and both ends of the second support roller are fixedly connected to the corresponding connecting seat and the side wall of the bracket by bolts.

[0010] As a further solution of the utility model: The first support roller and the two second support rollers are in a V shape.

[0011] As a further solution of the utility model: A baffle is sleeved on the outer end of the second support roller. The baffle is fixedly installed at the end of the second support roller by bolts, and a slope is arranged on the side of the baffle close to the second support roller.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. In the utility model, the handle is rotated to drive the screw rod, and the screw rod drives the connecting sleeve rotatably connected thereto to move up and down, so that the tensioning roller below the conveyor belt moves upward, and the tensioning roller above the conveyor belt moves downward, realizing the tensioning of the conveyor belt. After the conveyor belt is tensioned, the lock nut is tightened. The combined action of multiple tensioning mechanisms is beneficial to increasing the length of the conveyor belt that can be tensioned, and the positions of the two end driven rollers and the driving roller will not change during tensioning.

[0014] 2. When the utility model is in use, the conveyor belt is supported by the first support roller and the second support roller in the inner support mechanism. The first support roller and the second support roller rotate following the moving conveyor belt, avoiding the conveyor belt being in a suspended state over a long distance, reducing the deformation amount of the conveyor belt. And because the first support roller and the two second support rollers form a V shape, the conveyor belt supported by the first support roller and the second support roller is in a V shape, which is beneficial to the conveying of coal blocks by the conveyor belt and reduces the dropping of coal blocks during the conveying process.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a transportation drive belt includes a mounting frame 1. On both sides of one end of the mounting frame 1, first support frames 2 are symmetrically and fixedly installed. A driven roller 4 is rotatably installed between the first support frames 2 through a pedestal bearing. On both sides of the other end of the mounting frame 1, second support frames 3 are symmetrically and fixedly installed. A driving roller 5 is rotatably installed between the second support frames 3 through a pedestal bearing. A driving motor 6 is fixedly installed on the top of one of the second support frames 3. The output end of the driving motor 6 is fixedly connected to the end of the driving roller 5. Support mechanisms 9 are uniformly fixedly installed on the top of the mounting frame 1. A plurality of tensioning mechanisms 8 are uniformly arranged in the mounting frame 1. A conveyor belt 7 is wound between the driven roller 4 and the driving roller 5. The tensioning mechanisms 8 are arranged alternately on the upper and lower sides of the conveyor belt 7.

[0021] During use, the output end of the driving motor 6 drives the driving roller 5 to rotate. The driving roller 5 drives the conveyor belt 7 under the combined action of the driven roller 4 to convey coal blocks, realizing the transportation of coal blocks. The conveyor belt 7 is tensioned by a plurality of tensioning mechanisms 8 in the mounting frame 1. Since a plurality of tensioning mechanisms 8 are provided, it is beneficial to increase the length of the conveyor belt 7 that can be tensioned, and the positions of the driven roller 4 and the driving roller 5 at both ends will not change during tensioning.

[0022] The tensioning mechanism 8 includes a tensioning roller 10 which is a power-free roller. At both ends of the tensioning roller 10, strip-shaped holes 15 are provided in the columns of the mounting frame 1. The two ends of the tensioning roller 10 are built in the corresponding strip-shaped holes 15. Nuts 11 are threadedly connected to the ends of the tensioning roller 10 outside the mounting frame 1. A connecting sleeve 12 is sleeved outside the nuts 11 at the ends of the tensioning roller 10. A screw rod 14 is rotatably connected to the bottom end of the connecting sleeve 12. The screw rod 14 is threadedly connected through a cross plate 13 which is fixedly installed on the side wall of the column of the mounting frame 1. Loosen the nut 11 at the end of the tensioning roller 10, and by rotating the screw rod 14, the screw rod 14 drives the connecting sleeve 12 rotatably connected thereto to move up and down, so that the tensioning roller 10 below the conveyor belt 7 moves upward and the tensioning roller 10 above the conveyor belt 7 moves downward, realizing the tensioning of the conveyor belt 7. After the conveyor belt 7 is tensioned, lock the nut 11.

[0023] A handle is fixedly connected to the bottom end of the screw rod 14, which facilitates the rotation of the screw rod 14.

[0024] The support mechanism 9 includes a bracket 16 which is fixedly installed on the top of the mounting frame 1 by bolts. A first support roller 17 is arranged inside the bracket 16. Connecting seats 18 are fixedly installed at both ends of the first support roller 17 by bolts, and the connecting seats 18 are fixedly installed in the bracket 16 by bolts. A second support roller 19 is arranged between the side wall of the bracket 16 and the connecting seat 18. Both ends of the second support roller 19 are fixedly connected to the corresponding connecting seat 18 and the side wall of the bracket 16 by bolts. The first support roller 17 and the second support roller 19 are power-free rollers. The first support roller 17 and the second support roller 19 in the support mechanism 9 support the conveyor belt 7 in transmission. The first support roller 17 and the second support roller 19 rotate following the moving conveyor belt 7, avoiding the conveyor belt 7 being in a suspended state over a too long distance and reducing the deformation amount of the conveyor belt 7.

[0025] The first support roller 17 and the two second support rollers 19 are in a V shape. Since the first support roller 17 and the two second support rollers 19 form a V shape, the conveyor belt 7 supported by the first support roller 17 and the second support rollers 19 is in a V shape, which is beneficial to the conveying of coal blocks by the conveyor belt 7.

[0026] A baffle 20 is sleeved on the outer end of the second support roller 19. The baffle 20 is fixedly installed at the end of the second support roller 19 by bolts, and a slope is arranged on the side of the baffle 20 close to the second support roller 19. The baffle 20 arranged limits the conveyor belt 7 between the second support rollers 19 to prevent the conveyor belt 7 from shifting too much.

[0027] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
