Description

Technical Field

[0001] The utility model relates to the technical field of belt joints for mine belt conveyors, and particularly discloses a belt joint pressurizing pipeline and a belt joint pressurizing device. Background Art

[0002] Coal mine production systems primarily utilize belt conveyors for long-distance material transportation, effectively improving production and transportation efficiency. Mining belt conveyors, in particular, undergo a series of processes: belt frame installation, belt laying, and belt vulcanization. The quality of mining belt vulcanization joints directly impacts the overall quality of the production and transportation system, playing a crucial role in ensuring efficient operation of the raw coal conveying system.

[0003] The strength of the belt conveyor belt joint is determined by the quality of the vulcanization at the joint, that is, the adhesion at the joint must reach 80% to 90% of the breaking force to meet the requirements, so the quality of the joint vulcanization is crucial. The joint connection between each adjacent group of heating plates also has a significant impact on the quality of the vulcanized joint. In addition, if the iron block is placed at an incorrect angle or is not firmly fixed, the vulcanized belt joint is prone to burrs, which has a greater impact on the quality of the vulcanized joint. To solve the above problems, the patent with announcement number CN217752309U discloses a vulcanization molding mold for a strong belt joint for mining, including a lower mold and an upper mold, two side plates are provided on both sides of the upper surface of the lower mold, the two side plates are an integral structure with the lower mold, and a groove is formed between the two side plates. The lower surface of the upper mold is provided with a convex plate that engages with the groove, and the lower mold is provided with a quick fixing structure on both sides. The quick fixing structure includes a protrusion, a vertical rod, a top plate and a screw.

[0004] The above solution, suitable for hydraulic pressurization devices, requires an additional hydraulic circulation system, which is relatively costly. Prior art uses water as the pressurizing medium to apply pressure to the hydraulic platen, which in turn applies pressure to the joint. In practice, two conventional pressurization methods are commonly used: electric and manual pumps. These methods carry the risk of unstable pressurization due to failure during the pressurization process. Furthermore, the unstable fixation of the hydraulic bag within the existing hydraulic platen can easily lead to uneven pressure application from the hydraulic platen to the center platen, compromising the quality of the vulcanized joint. Utility Model Content

[0005] In response to the above-mentioned shortcomings of the prior art, the utility model provides a tape joint pressurizing pipeline and a tape joint pressurizing device to solve the hidden danger of unstable pressurization caused by failure in the pressurization process; furthermore, the water pressure bag in the existing water pressure plate is not fixed stably, which easily leads to uneven pressurization of the water pressure plate on the middle pressure plate, affecting the quality of the vulcanized joint.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A tape joint pressurized pipeline includes several water supply pipes radially connected to a main pipeline. The main pipeline is connected to two pressurized pipelines, which are spaced apart and parallel to each other. The two pressurized pipelines are connected to an electric pressurized pump and a manual pressurized pump, respectively. The main pipeline is also connected to a fire water pipeline. Both the pressurized pipelines and the fire water pipeline are equipped with manual valves. One end of the main pipeline is closed, and the other end is connected to a pressure regulating assembly. The fire water pipeline arrangement enables pressurization using fire water to ensure stable pressure. The pressure regulating assembly allows timely adjustment of the pressure in the main pipeline, further ensuring stable pressure.

[0008] Preferably, the pressure regulating assembly includes a manual pressure reducing valve and a pressure gauge, which facilitates timely monitoring of the main line pressure and adjustment of the manual pressure reducing valve to ensure stable pressurization.

[0009] Preferably, both the pressurized pipes and the fire water pipe are equipped with a one-way valve between the manual valve and the main pipe. This valve reduces the impact of other branch pipes on the water pressure in the main pipe when using the electric booster pump, manual booster pump, and fire water for pressurization, ensuring stable pressurization.

[0010] A tape joint pressurizing device comprises several tape joint pressurizing dies. Each pressurizing die comprises an upper and lower pressurizing plate connected by a screw. The screws are threaded at both ends and have a smooth rod in the middle. A middle pressurizing plate is slidably mounted in the middle of the screws. A water pressure plate is positioned between the middle and upper pressurizing plates. A water pressure bag is located within the water pressure plate. The water inlet of the water pressure bag is connected to the water supply pipe of the tape joint pressurizing pipeline. This tape joint pressurizing pipeline ensures stable pressurization of the water pressure plate and the quality of the vulcanized joint.

[0011] Preferably, a plurality of sleeve rods are provided at the edge of the upper pressure plate, and sleeves are provided on the upper surface of the intermediate pressure plate to cooperate with the sleeve rods, so as to ensure the stability of the movement of the intermediate pressure plate and the stability of the pressurization.

[0012] Preferably, the hydraulic plate comprises a base and an upper cover; the outer peripheral wall of the upper cover is provided with an annular platform that mates with the base; the annular platform is buckled onto the outside of the base; both the base and the upper cover are provided with grooves; a hydraulic bag is placed in the groove; and the water inlet of the hydraulic bag is provided through the outer wall of the upper cover. This ensures that the hydraulic bag is stably positioned between the upper cover and the base, that the pressure of the hydraulic bag is evenly applied, and that the quality of the vulcanized joint is guaranteed.

[0013] Preferably, a plurality of guide rods are provided on the upper end surface of the base, and a plurality of recesses are provided on the bottom surface of the upper cover to match the guide rods, thereby ensuring the stability of the upper cover in moving on the base.

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

[0015] 1. By setting up the fire water pipeline, the fire water can be used to pressurize the water pressure plate to ensure the stability of the pressurization. By setting up the pressure regulating component, the pressure in the main pipeline can be adjusted in time to further ensure the stability of the pressurization.

[0016] 2. Through the reasonable setting of the water pressure plate, the stability of the water pressure bag between the upper cover and the base is ensured, the pressure of the water pressure bag is evenly applied, and the quality of the vulcanized joint is guaranteed.

The pressure regulating component includes a manual pressure reducing valve 14 and a pressure gauge 6, which is convenient for timely monitoring the pressure of the main pipeline 2 and adjusting the manual pressure reducing valve 14 to ensure stable pressurization. Both pressurized pipes 3 and the fire water pipe 4 are equipped with check valves 7, which are located between the manual valve 5 and the main pipe 2. The check valves reduce the impact of other branch pipes on the water pressure in the main pipe when the electric booster pump, manual booster pump, and fire water are used independently for pressurization, ensuring stable pressure.

[0028] Example 2

[0029] like Figure 2-4 As shown, a tape joint pressurizing device utilizes the tape joint pressurizing pipeline of Example 1, comprising four tape joint pressurizing molds.

[0030] In the above arrangement, a plurality of sleeve rods 901 are provided at the edge of the upper pressure plate 9; sleeves 1101 are provided on the upper surface of the intermediate pressure plate 11 to cooperate with the sleeve rods 901, and the sleeves 1101 are respectively plugged into the corresponding sleeve rods 901 to ensure the stable movement of the intermediate pressure plate 11 and the stable pressurization.

[0031] The hydraulic plate 12 comprises a base 1201 and a cover 1202. The outer wall of the cover 1202 is fitted with an annular platform 1203 that mates with the base 1201. The platform 1203 snaps onto the outside of the base 1201. Both the base 1201 and the cover 1202 are provided with grooves, within which a hydraulic bag 13 is placed. The water inlet 1301 of the hydraulic bag 13 extends through the outer wall of the cover 1202. This ensures the hydraulic bag 13 is stably positioned between the cover 1202 and the base 1201, ensuring uniform pressure application and ensuring the quality of the vulcanized joint. The upper surface of the base 1201 is provided with several guide rods 1204. The bottom surface of the cover 1202 is provided with clearance grooves 1205 that mate with the guide rods 1204.
