[0002] The anti-expansion tube of the tubular belt conveyor is a key component of the core safety protection system of the tubular belt conveyor. Its core function is to prevent abnormal expansion of the conveyor belt during the tube forming process due to material blockage or uneven distribution, thereby ensuring stable operation of the equipment and avoiding production interruption and property loss.

[0003] In the prior art, tubular belt conveyors usually require anti-expansion devices during use. According to the content of Chinese utility model patent with patent publication number CN213504537U, the anti-expansion method in this device generally prevents the expansion of the tube expansion accident by controlling the working state of the tubular belt, but it cannot avoid the occurrence of tube expansion accidents and urgently needs improvement.

[0004] To address the aforementioned technical shortcomings, a solution is proposed that can level the stockpiled material to the required height in real time according to actual needs, thereby minimizing the risk of pipe bulging caused by blockages and improving overall work efficiency. Utility Model Content

[0006] The purpose of this utility model can be achieved through the following technical solution: a tube expansion prevention pipe for a tube conveyor, including a mounting plate and a mounting rod that is snapped onto the mounting plate. A hydraulic cylinder is fixedly installed in the middle of the upper side of the mounting rod. A telescopic rod that passes through the mounting rod is installed on the hydraulic cylinder. A lifting plate is fixedly connected to the bottom end of the telescopic rod. Two sets of limiting vertical rods are fixedly connected to the upper side of the lifting plate.

[0011] Preferably, the first scraper is movably connected to the first side frame, the second scraper is movably connected to the second side frame, and several sets of first scrapers and several sets of second scrapers are alternately arranged, with the spring located on the upper side of the baffle.

[0012] Preferably, the mounting bracket is in the shape of an inverted U, and two sets of limiting sliding holes are provided through the mounting bracket.

[0014] The beneficial effects of this utility model are:

[0015] (1) By starting the hydraulic cylinder on the upper side of the mounting frame, the telescopic rod is extended and retracted, thereby driving the lifting frame plate to move up and down under the cooperation of the limiting vertical rod and the limiting sliding hole until the rotating plate is at the target height position.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: The application background of this utility model is based on the material conveying process of the tubular belt conveyor. During this conveying process, it is necessary to prevent and improve the tube expansion situation. The technical solution of this utility model is to solve the problem of the tube expansion prevention method in the existing device. It generally prevents the expansion accident from expanding by controlling the working state of the tubular belt, but it cannot avoid the occurrence of the tube expansion accident.

[0026] Please see Figures 1-5 As shown, this embodiment is a tube expansion prevention device for a tube conveyor, including a mounting plate 1 and a mounting rod 8 that is snapped onto the mounting plate 1. A hydraulic cylinder 9 is fixedly installed in the middle of the upper side of the mounting rod 8. A telescopic rod 10 that passes through the mounting rod 8 is installed on the hydraulic cylinder 9. A lifting plate 11 is fixedly connected to the bottom end of the telescopic rod 10. Two sets of limiting vertical rods 12 are fixedly connected to the upper side of the lifting plate 11. A frame 14 is fixedly connected to the lower side of the lifting plate 11. A drive shaft 16 is provided through the middle of the frame 14. Several sets of rotating plates 17 are fixedly connected to the drive shaft 16.

[0027] Several sets of intermediate frames 2 are fixed at equal intervals in the middle of the mounting plate 1. A first shaft 3 is fixed through the intermediate frame 2. A first movable roller 4 is movably sleeved on the first shaft 3. Several sets of inclined frames 5 are fixed at equal intervals on both sides of the mounting plate 1. A second shaft 6 is fixed through the inclined frame 5. A second movable roller 7 is movably sleeved on the second shaft 6. The cooperation of several sets of first movable rollers 4 and several sets of second movable rollers 7 is used to provide auxiliary transmission for the conveyor belt.

[0028] The mounting frame 8 is in the shape of an inverted U. Two sets of limiting sliding holes 13 are opened through the mounting frame 8. Two sets of limiting vertical rods 12 are symmetrically arranged about the telescopic rod 10, and the limiting vertical rods 12 are located inside the limiting sliding holes 13. The telescopic rod 10 is extended and retracted by the hydraulic cylinder 9, thereby driving the lifting frame plate 11 to move up and down, so as to adjust the height position of the rotating plate 17.

[0029] A drive motor 15 is mounted in the middle of one side of the frame 14, and the output shaft of the drive motor 15 is connected to the transmission shaft 16 through a coupling. Several sets of rotating plates 17 are evenly distributed on the transmission shaft 16, and the several sets of rotating plates 17 are all located inside the frame 14. The transmission shaft 16 causes the several sets of rotating plates 17 to rotate together, thereby pushing and dispersing the high-pile material.

[0030] Specifically, by activating the hydraulic cylinder 9 on the upper side of the mounting frame 8, the telescopic rod 10 is extended and retracted. This, in conjunction with the limiting vertical rod 12 and the limiting sliding hole 13, causes the lifting frame plate 11 to move up and down until the rotating plate 17 is at the target height. Then, the drive motor 15 on one side of the frame 14 is activated to drive the transmission shaft 16 to rotate, thereby causing several sets of rotating plates 17 to rotate until the material piled high on the conveyor belt is flattened and dispersed. This allows the high-pile material to be flattened to the required height in real time according to actual needs, minimizing the occurrence of pipe expansion caused by blockage and improving overall work efficiency.

[0031] Example 2: Please refer to Figures 1-5 As shown, this embodiment is a tube expansion prevention device for a tube conveyor. The first side frame 18 and the second side frame 19 are fixedly connected to the two sides of the frame 14 respectively. Several sets of first scraper rods 20 are provided through the first side frame 18, and several sets of second scraper rods 21 are provided through the second side frame 19. A baffle 22 is fixedly sleeved on both the first scraper rod 20 and the second scraper rod 21, and a spring 23 is sleeved on both the first scraper rod 20 and the second scraper rod 21.

[0032] The first scraper 20 is movably connected to the first side frame 18, and the second scraper 21 is movably connected to the second side frame 19. Several sets of first scrapers 20 and several sets of second scrapers 21 are arranged alternately. The spring 23 is located on the upper side of the baffle 22. The materials stubbornly adhering to the conveyor belt are scraped off by the several sets of first scrapers 20 and several sets of second scrapers 21 arranged alternately.

[0033] Specifically, when the rotating plate 17 moves to the target height position, the lower ends of several sets of first scrapers 20 and several sets of second scrapers 21 are tightly attached to the conveyor belt through the cooperation of spring 23 and baffle 22. The materials stubbornly adhering to the conveyor belt are scraped off by the several sets of first scrapers 20 and several sets of second scrapers 21 arranged in an alternating manner, which can prevent some materials from stubbornly adhering to the conveyor belt and causing material accumulation, and further prevent the tube expansion phenomenon.

[0034] As can be seen from Embodiments 1 and 2, by activating the hydraulic cylinder 9 on the upper side of the mounting frame 8, the telescopic rod 10 is driven to extend and retract, thereby driving the lifting frame plate 11 to move up and down under the cooperation of the limiting vertical rod 12 and the limiting sliding hole 13, until the rotating plate 17 is at the target height position. Then, the drive motor 15 on one side of the frame 14 is activated to drive the transmission shaft 16 to rotate, thereby driving several sets of rotating plates 17 to rotate, until the material piled high on the conveyor belt is flattened and dispersed. It can push the high pile of material to the required height in real time according to actual needs, so as to avoid the expansion of the pipe due to blockage to the greatest extent, which is conducive to improving the overall work efficiency.

[0035] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
