[0002] A power reverse thrust device for splicing large-diameter cast iron pipes, primarily consisting of a hydraulic system, a reverse thrust device body, connection components, and a control system. The reverse thrust device uses hydraulic power as its primary driving source, utilizing a hydraulic cylinder to propel the device body. The reaction force is transmitted to the ends of the cast iron pipes to be spliced, thereby achieving pipe splicing. Its working principle is to use a hydraulic cylinder to push the reverse thrust head into contact with the end face of the pipe, gradually and tightly docking the two sections of large-diameter cast iron pipes through a uniform and stable force, ensuring the stability of the splicing.

[0037] In this embodiment: through the fixed connection between the first support frame 1 and the second support frame 3, the third support frame 4, the fourth support frame 24, and the fifth support frame 25, a stable support structure is formed, which enhances the overall stability of the equipment. The structure can bear the weight of the equipment and ensure smooth operation during the pipe splicing process. The setting of the buffer device 5 effectively reduces the damage of the equipment to the ground and improves the stability of the equipment by increasing the friction with the ground. The design of the sleepers can prevent the equipment from tilting during operation, ensuring the safety and accuracy of the equipment in use.

[0038] Specifically, such as Figure 1-8 As shown, the thickness of the second sleeper 7 at the rear side is 0.8 times that of the first sleeper 6, which is used to prevent the device from tilting during use. A groove 9 is provided above the first sleeper 6 and the second sleeper 7, and an opening 32 is formed between the auxiliary fixing frames on the left and right sides.

[0039] In this embodiment: through the design of the auxiliary support device, the equipment can slide up and down during use and adjust the height to ensure that the equipment is evenly stressed under different working conditions. This design improves the flexibility of the equipment and reduces the difficulty of operation.

[0046] In this embodiment: the hydraulic rod 17 is the core component of the power assembly, which provides a strong power transmission capability to ensure efficient advancement during the pipeline splicing process. The hydraulic oil inlet and outlet design of the hydraulic rod 17 facilitates the maintenance and operation of the hydraulic system.

[0047] Specifically, such as Figure 1-8 As shown, the support assembly includes a first support plate 20, a second support plate 21, a second connecting rod 22 and an extrusion ring 23. The first support plate 20 is fixedly connected to the second connecting rod 22, the second support plate 21 is fixedly connected to the second connecting rod 22, the first support plate 20 is fixedly connected to the fifth support frame 25, and the output end of the hydraulic rod 17 is fixedly connected to the extrusion ring 23.

[0048] In this embodiment, the support assembly ensures the structural stability of the equipment through the design of the first support plate 20, the second support plate 21, the second connecting rod 22 and the extrusion ring 23. In particular, the role of the extrusion ring 23 makes the force more uniform and avoids excessive local stress.

[0049] Specifically, such as Figure 8 As shown, an annular hole 31 is formed inside the extrusion ring 23, and the extrusion ring 23 is annular.

The different thickness design of the sleepers avoids tilting during use of the device. The auxiliary support device is sleeved on the outside of the second support frame 3. The up and down sliding function of the first fixed sleeve 11 can adjust the height of the equipment to adapt to different working scenarios. This design makes the force more uniform and the operation more flexible, reducing the difficulty of operation caused by the weight of the equipment and the unevenness of the site. The design of the third lifting ring 15 and the limit bolt 29 makes the equipment more convenient when hoisting or moving. At the same time, the limit bolt 29 also prevents the equipment from being displaced during use, thereby improving the safety of operation. The reverse thrust device 16 is the core part of the equipment and includes a hydraulic rod 17, a second fixed sleeve 18 and a metal rod 19. The hydraulic rod 17 provides stable power by Output, pushes the extrusion ring 23, so that the force during the pipe splicing process is uniform and efficient. The annular structure of the extrusion ring 23 and the internal annular hole 31 design enable it to effectively disperse the pressure when subjected to force, avoid excessive local stress, and at the same time enhance the stability of the entire device. The support assembly is fixed by the first support plate 20, the second support plate 21 and the second connecting rod 22 to ensure the stability of the equipment structure and safety during operation. The reinforcement of the first side plate 2 and the second side plate 26 further improves the strength of the support frame, making the equipment more stable in different usage scenarios and not prone to tilting or deformation. The center hole 34 design of the equipment makes the entire structure stable while reducing the weight of the equipment and improving convenience.
