Description

Technical Field

[0001] The utility model relates to the technical field of coal pipes, in particular to a four-drop coal pipe with a buffering function. Background Technique

[0002] In coal mines, "four-drop coal pipes" usually refer to a system for underground transportation and discharge in coal mines. Specifically, they are key facilities in coal mine shafts, responsible for transporting coal from the mining area to the hoisting system or the ground of the mine. These pipes are an important part of the internal infrastructure of the mine shaft and are crucial for ensuring the normal operation, safe production, and efficient transportation of coal mines.

[0003] Existing coal pipes are generally inclined during the transportation of coal, aiming to reduce the impact force during the falling transportation of coal. However, the existing coal pipes cannot adjust their inclination angles, thus unable to control the transportation speed, which reduces the practicality of the device. The connection at the bottom end of the coal pipe cannot effectively buffer the falling of coal, thereby increasing the instability during transportation and being unfavorable to the transportation efficiency and safety of coal. Content of the Utility Model

[0004] The purpose of the utility model is to provide a four-drop coal pipe with a buffering function to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, a four-drop coal pipe with a buffering function provided by the utility model includes a plurality of coal pipe bodies. Flexible bellows are fixedly installed at both ends of the plurality of coal pipe bodies. One end of each two flexible bellows is fixedly installed with a transfer box. A buffering function component is arranged inside the transfer box, and a coal pipe angle adjustment component is arranged on the outer surface of the transfer box;

[0006] The buffering function component includes a feeding port and a discharging port respectively opened on the upper and lower surfaces of the transfer box.

Specific embodiments

[0020] 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.

[0021] Please refer to Figures 1-4, the present utility model provides a technical solution: including a plurality of coal pipe bodies 1, flexible bellows 2 are fixedly installed at both ends of the plurality of coal pipe bodies 1, one end of every two flexible bellows 2 is fixedly installed with a transfer box 3, a buffer function component 4 is arranged inside the transfer box 3, and a coal pipe angle adjustment component 5 is arranged on the outer surface of the transfer box 3. The buffer function component 4 includes a feeding port and a discharging port respectively opened on the upper and lower surfaces of the transfer box 3. Flexible bellows 2 are fixedly installed on the surfaces of the feeding port and the discharging port. A telescopic buffer plate 401 is arranged below the feeding port. Both sides inside the telescopic buffer plate 401 are provided with first buffer springs 402. A flow-condensing seat 403 is arranged on the upper surface of the discharging port. A flow-condensing groove is opened on the surface of the flow-condensing seat 403, and the flow-condensing groove is communicated with the discharging port. One side of the telescopic buffer plate 401 is fixedly installed with a clamping column, and the clamping column is rotatably connected to the inner side wall of the transfer box 3. Both sides of the lower surface of the inner plate of the telescopic buffer plate 401 are rotatably connected with buffer rods 404 through movable seats. The other ends of the buffer rods 404 are rotatably connected with sliding blocks through movable seats. The outer surface of the sliding block is slidably connected with a guide rail 405, and the guide rail 405 is fixedly installed on the inner bottom wall of the transfer box 3. One side surface of the sliding block is fixedly installed with a second buffer spring 406, and the second buffer spring 406 is fixedly installed on the inner side wall of the guide rail 405.

[0022] When the coal descends and is transported inside the coal pipe body 1, the coal drops through the feeding port onto the upper surface of the telescopic buffer plate 401. At this time, the telescopic buffer plate 401 is stressed and rotates and contracts. During the contraction process, the first buffer spring 402 inside is squeezed. During the rotation process, the telescopic buffer plate 401 drives the buffer rod 404 and the sliding block at one end to slide inside the guide rail 405. During the sliding process, the second buffer spring 406 inside is squeezed. The impact force of the coal falling is absorbed and buffered by the first buffer spring 402 and the second buffer spring 406, improving the stability of the coal during transportation, and improving the transportation efficiency and safety of the coal. The coal slides onto the flow-condensing groove on the surface of the flow-condensing seat 403 through the inclined telescopic buffer plate 401, and then the coal continues to be transported downward through the discharging port.

[0023] Refer to Figure 3 , guide columns are fixedly installed on both side surfaces of the inner plate of the telescopic buffer plate 401, and first guide grooves are opened on both sides of the inner side wall of the transfer box 3. The guide columns are slidably connected inside the first guide grooves.

[0024] The telescopic buffer plate 401 drives the guide columns to slide inside the first guide grooves, thereby guiding the position of the telescopic buffer plate 401, ensuring that one end of the telescopic buffer plate 401 always clings to the inner side wall of the transfer box 3 during movement, and avoiding the leakage of coal.

[0025] Refer to Figure 3, the coal pipe angle adjustment assembly 5 includes a bearing frame 501 disposed on the outer surface of several transfer boxes 3. Connecting members are fixedly installed on both the upper and lower surfaces of the middle transfer box 3, and the connecting members are fixedly installed on the inner sidewall of the bearing frame 501. Guide rods 502 are fixedly installed on both side surfaces of the upper and lower transfer boxes 3, and first chutes are provided on the inner sidewalls of the upper and lower transfer boxes 3. The guide rods 502 are slidably connected inside the first chutes.

[0026] During the movement of the transfer box 3, the guide rods 502 are driven to slide inside the first chutes, ensuring the stability of the transfer box 3 during sliding.

[0027] Refer to Figure 3 , the coal pipe angle adjustment assembly 5 includes a fixed block fixedly installed on the lower surface of the transfer box 3. A lead screw 503 is threadedly connected inside the fixed block. One end of the lead screw 503 is fixedly installed with a driven column, and pulley wheels are fixedly installed on the outer surfaces of the two driven columns and a belt is lapped thereover.

[0028] Through the setting of the pulley wheels, the synchronous rotation of the lead screws 503 on both the upper and lower sides is achieved, so that the lead screw 503 on the other side rotates synchronously, and then the fixed block is driven to move.

[0029] Refer to Figure 2 And Figure 3 , a driving motor 504 is fixedly installed on the inner sidewall of the transfer box 3. The output end of the driving motor 504 is fixedly installed with a driving shaft. Pulley wheels are fixedly installed on the outer surface of the driving shaft and one of the driven columns and a belt is lapped thereover. The driving shaft rotates through and is connected to the side surface of the transfer box 3.

[0030] By starting the driving motor 504, the synchronous rotation of the lead screws 503 on both the upper and lower sides is achieved, reducing the power source required during driving, and thus reducing the working cost.

[0031] Refer to Figure 2 And Figure 3 , connecting rods are fixedly installed between several bearing frames 501. The number of connecting rods is several. Mounting rods are fixedly installed on both side surfaces of several bearing frames 501, and bolts are threadedly connected to the surfaces of the mounting rods.

[0032] Through the setting of the mounting rods and bolts, the bearing frame 501 can be quickly installed and limited, thereby playing a supporting role for the overall device.

[0033] Working principle:

[0034] The work can first adjust the inclination angle of the coal pipe body 1. Start the driving motor 504 to drive the driving shaft to rotate. The connection between the driving shaft and the belt pulley makes the driven columns on both the upper and lower sides rotate synchronously. The driven columns drive the lead screw 503 at one end to rotate. The rotation of the lead screw 503 causes the connecting piece to drive the transfer box 3 on the upper surface to move. The transfer box 3 drives the guide rod 502 to slide inside the first chute on the inner side wall of the bearing frame 501. The transfer box 3 drives the flexible bellows pipes 2 on both the upper and lower sides to move. Due to the flexibility of the flexible bellows pipes 2 having a certain expansion force, it drives the coal pipe body 1 to perform an inclination operation, making the coal pipe body 1 in an inclined state. When the coal descends and is transported from the inside of the coal pipe body 1, the coal drops through the feeding port onto the upper surface of the telescopic buffer plate 401. At this time, the telescopic buffer plate 401 is stressed and rotates and contracts. During the contraction process, it squeezes the first buffer spring 402 inside. During the rotation process, the telescopic buffer plate 401 drives the buffer rod 404 and the sliding block at one end to slide inside the guide rail 405. During the sliding process, it squeezes the second buffer spring 406 inside. The impact force of the coal dropping is absorbed and buffered by the first buffer spring 402 and the second buffer spring 406, improving the stability of the coal during transportation, as well as the transportation efficiency and safety of the coal. The coal slides down the inclined telescopic buffer plate 401 into the flow-accumulating groove on the surface of the flow-accumulating seat 403, and then the coal continues to be transported downward through the feeding port.
