Description

Technical Field

[0001] The utility model belongs to the technical field of electromechanical transportation of coal mines, in particular to an electromechanical transportation device for coal mines above the well. Background Art

[0002] Electromechanical transportation in coal mines is a mechanical device used to transport coal and gangue, such as scrapers, chain conveyors, belt conveyors, etc. Among them, belt conveyors are widely used in the industry, especially in coal mining, because they can transport coal over long distances, with large transport volumes and high transport stability. Specifically, in coal mining, belt conveyors can transport large amounts of coal, gangue and other materials.

[0003] The main structure of the belt conveyor includes a frame, rollers mounted on the frame, and a head and tail with belt drums mounted. Specifically, the belt is driven on the belt drums on the head and tail. The driven belt transports the coal.

[0004] However, in actual work, it is found that when the transmission belt is loaded with a large amount of coal or gangue, the belt is prone to loosening, which leads to poor stability of the belt transmission and is very likely to be misaligned during the transmission process.

[0005] At the same time, as the belt is used for a long time, it ages seriously and is prone to being too loose, which leads to the belt being easily tied. It is difficult to tighten a loose belt, especially because it is very difficult and cumbersome to adjust the belt due to the heavy head and tail. In the actual working process, the tension often needs to be adjusted according to the amount of material loaded and the degree of belt aging. Therefore, it is necessary to adjust the belt repeatedly during the actual working process. Obviously, if the belt cannot be adjusted flexibly and labor-savingly, it will undoubtedly increase the difficulty of belt conveyor operation. Utility Model Content

[0044] Example 1

[0045] like Figure 1-5As shown, an electromechanical transportation device for an underground coal mine includes a conveyor frame 1, and the two ends of the conveyor frame 1 are respectively equipped with a tensioning belt drum mechanism 2, and the tensioning belt drum mechanism 2 includes belt drum seats 21 arranged at intervals on both sides, and a belt drum 22 is rotatably connected between the belt drum seats 21. The belt drums 22 are connected to each other in a transmission manner. Belts (not shown in the figure) are also connected between the belt drums 22. At the same time, the tensioning belt drum mechanism 2 also includes a driving motor for driving the belt drum, and the driving motor is fixedly mounted on the belt drum seat 21.

[0046] In order to achieve tension, such as when the belt is loose or the belt load is too large, the belt drum seat 21 is provided with a long sliding opening 211 at the top and bottom. Correspondingly, the top and bottom of the conveyor frame 1 are respectively fixedly connected with a sliding screw 212 passing through the long sliding opening 211, and a locking nut is threadedly connected to the sliding screw 212.

[0047] Loosen the locking nut to enable the belt drum seat 21 to slide with the belt drum, and adjust the tension of the belt during the sliding process.

[0048] Specifically, the tensioning belt drum mechanism 2 also includes a tensioning assembly, which includes a tensioning motor 23 (the bottom of the tensioning motor 23 is fixedly installed on the motor bracket in a conventional manner disclosed in the prior art), and the tensioning motor 23 is equipped with a winding wheel 231, and the winding wheel 231 is wound with a traction rope 24 for pulling the belt drum seat 21.

[0049] Specifically, the traction rope 24 includes a V-shaped rope portion fixedly connected to the front and rear end positions of the conveyor frame 1 , and the V-shaped rope portion is hung with a horizontal rope portion, and the horizontal rope portion is wound on the winding wheel 231 .

[0050] During operation, when the belt needs to be tightened, the locking nut is loosened in the above manner, and the tensioning motor 23 is used to drive the winding wheel 231 to rotate, and the belt drum seat 21-belt drum structure is pulled by the traction rope 24, and the locking nut is locked after adjustment.

[0051] This method can be used to pull the heavy belt drum seat 21-belt drum 22 structure flexibly and labor-savingly during the working process, and the belt can be tensioned after pulling. The above method is convenient for pulling and tensioning. And because it can be flexibly adjusted, it can be adjusted in real time and quickly according to the condition of the belt and the load condition.

[0052] Example 2

[0053] like Figure 1-5As shown, in this embodiment, based on the structure of embodiment 1, the tensioning belt drum mechanism 2 further includes an elastic reset component. The elastic reset component can be used to quickly reset the tensioning belt drum mechanism 2 when the tension is excessively adjusted, such as when the tension is adjusted too large, to achieve flexible switching between tension and relaxation.

[0054] Specifically, the elastic reset assembly includes reset slide rods 25 respectively fixedly connected to the belt drum seat 21, and the reset slide rod 25 is slidably connected to the conveyor frame 1; a reinforcing spring 251 is sleeved on the reset slide rod 25, and the two ends of the reinforcing spring 251 are respectively fixedly connected to the belt drum seat 21 and the conveyor frame 1.

[0055] Specifically, a rectangular sliding opening is provided on the belt drum seat 21; a reset slide bar 25 is fixedly connected to the side wall of the rectangular sliding opening; and an inner sliding groove (with a certain depth) is provided on the corresponding conveyor frame 1 to slideably connect the reset slide bar 25. During the tensioning process, the reinforcing spring 251 pulls the rope. When the tension is excessive and the belt needs to be relaxed, the tensioning motor 23 reversely unwinds the rope, and the belt drum seat 21 is gradually reset with the cooperation of the strong spring restoring force of the reinforcing spring 251. During the resetting process, the belt is relaxed until it reaches a suitable tensioning force.

[0056] Example 3

[0058] At the same time, the bottom of the base 35 is fixedly assembled and connected with a correction motor 33 that drives the roller frame 31 to rotate (same as the existing method, the correction motor 33 is fixedly installed at the bottom of the base 35); and the output shaft of the correction motor 33 is fixedly connected to the bottom of the roller frame 31.

[0059] At the same time, the bottom sides of the roller frame 31 are respectively equipped with supporting rollers 341 that roll on the top position of the base 35. The rollers include a roller frame 34 fixedly installed at the bottom of the base 35, and the rollers 341 are installed on the roller frame 34.

[0060] During operation, when the belt and the roller are offset, the correction motor 33 (using a forward and reverse motor) is turned on to drive the roller frame 31 - roller structure to rotate until the roller can continue to support the bottom of the belt. Correction is achieved in this way.

[0061] At the same time, during the rotation of the roller frame 31-roller structure, the roller support rolls on the top of the base 35, thereby maintaining the stability of the rotation correction and the stability of the supporting belt.

[0062] The front and rear ends of the base 35 are provided with bayonet holes, and a T-shaped connecting plate 36 is fixedly connected in the bayonet hole, and the T-shaped connecting plate 36 is fixedly connected to the inner wall of the conveyor frame 1. The front and rear ends of the base 35 are respectively fixedly connected with a pin-fixing screw 361 that passes through the T-shaped connecting plate, and a nut is threadedly connected to the end of the pin-fixing screw 361. In this way, the base 35 can be disassembled. Specifically, the pin-fixing screw 361 can be disassembled by loosening the nut and then pulling out the pin-fixing screw 361.

[0063] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples.
