Description

Technical Field

[0001] This invention relates to the field of municipal sewage pipe technology, specifically to a long-distance pipe jacking device for municipal sewage concrete pipes. Background Technology

[0002] Concrete pipes are pipes made of concrete or reinforced concrete, used to transport fluids such as water, oil, and gas. Long-distance concrete pipe jacking refers to the process of pushing, pulling, or advancing concrete pipes section by section into the ground or groundwater to build a long pipeline.

[0003] Because the concrete pipes are placed on uneven construction sites, they are prone to shifting and tilting when being pushed forward. This requires multiple manual guidance and corrections to ensure the pipes are pushed in a straight line, which greatly affects work efficiency. Secondly, the length of the concrete pipes varies, and the distance to be pushed also varies. When a long distance needs to be pushed, the equipment cannot push the pipes far enough to complete the push in one go. Summary of the Invention

[0004] Technical problem to be solved: The present invention provides a long-distance pipe jacking device for municipal sewage concrete pipes, which can solve the problems mentioned in the background art.

[0005] Technical Solution: To achieve the above objectives, the present invention adopts the following technical solution: a long-distance pipe jacking device for municipal sewage concrete pipes, comprising a mounting base, main jacking cylinders, an extension and moving mechanism, and a limiting and pushing mechanism. The mounting base is mounted on a wall, and an extension and moving mechanism is slidably mounted on the mounting base. Multiple main jacking cylinders are evenly mounted on the left end of the extension and moving mechanism. The main jacking cylinders are multi-stage telescopic cylinders, and the telescopic ends of the main jacking cylinders are all connected to the limiting and pushing mechanism.

[0006] The mounting base includes a main board, which is fixedly mounted on the wall. Side support plates are symmetrically mounted on the rear and lower sides of the end face of the main board away from the wall. The side support plates are fixedly mounted to the wall, and the two side support plates are connected by multiple vertical connecting rods.

[0007] The extended moving mechanism includes a displacement seat, which is mounted on a mounting base. Sliding grooves are provided on the side support plates. Electric sliders are installed at corresponding positions of the displacement seat and the sliding grooves. The electric sliders are slidably disposed in the sliding grooves. Positioning holes are provided in the sliding grooves at the positions of the vertical connecting rods. Docking grooves are provided on the electric sliders. Cavities are provided inside the vertical connecting rods. Locking elements are provided inside the cavities to stably fix the displacement seat after displacement.

[0008] The limiting and pushing mechanism includes a disc abutment plate. The right end face of the disc abutment plate is connected to the telescopic end of the main top oil cylinder. A positioning unit for limiting and supporting the inner wall of the concrete pipe is installed in the middle of the left end face of the disc abutment plate. Multiple sets of limiting units for clamping and limiting the outer wall of the concrete pipe are evenly arranged on the left end face of the disc abutment plate near the outer wall.

[0009] Preferably, the locking element includes a bidirectional telescopic rod, which is installed inside the cavity, and each telescopic end of the bidirectional telescopic rod is equipped with a locking rod.

[0010] Preferably, the positioning unit includes a cylindrical block, which is installed in the middle of the left end face of the disc abutment. The outer wall of the cylindrical block is provided with grooves, and rubber strips are provided in the grooves. A guide block is installed on the left end face of the cylindrical block. The guide block has a frustum structure and its outer wall is uniformly fitted with balls.

[0011] Preferably, the limiting unit includes connecting rods symmetrically installed on the left end face of the disc abutment plate. Multiple round shafts are evenly installed between the two connecting rods. The outer walls of the round shafts are rotatably mounted with outer abutment plates via torsion springs. The side of the outer abutment plate closest to the positioning unit has an arc structure. The end of the outer abutment plate away from the positioning unit is connected by a steel rope. The other end of the steel rope is connected to the output end of the forward and reverse motor. The forward and reverse motor is embedded in the middle of the right end face of the disc abutment plate.

[0012] Preferably, the outer wall of the disc abutment is provided with notches at positions corresponding to the steel rope, and a rotating roller is rotatably installed at the notch position, with the steel rope fitting against the outer wall of the rotating roller.

[0013] Preferably, the left end face of the main board is uniformly equipped with fixing rods near the outer wall, and the left end face of each fixing rod is connected to the supporting circular plate. The supporting circular plate is provided with circular holes at the corresponding positions of the main top oil cylinder, and the inner wall of each circular hole is equipped with ball bearings. The diameter of the circular hole corresponds to the secondary extension diameter of the main top oil cylinder.

[0014] The beneficial effects are as follows:

[0015] 1. The limiting and pushing mechanism restricts the contact between the inner and outer walls of the concrete pipe, ensuring the linear movement and stability of the concrete pipe. The main top cylinder and the extension moving mechanism work together to extend the pushing distance according to the different positions the concrete needs to reach, thereby improving adaptability. In addition, the locking part and the supporting circular plate work together to ensure the stability during the pushing operation.

[0016] 2. The disc abutment moves to contact the end face of the concrete pipe. At the same time, the guide block, ball bearings and cylindrical block cooperate to ensure that the inner wall of the concrete pipe is in contact after centering and adjustment. Meanwhile, multiple outer abutment plates of the limiting unit also move to the outer wall position of the concrete pipe to limit and fix the outer wall at multiple points. The cooperation of limiting the inner and outer walls of the concrete pipe greatly improves the stability and accurate pushing of the concrete pipe.

[0017] 3. By cooperating with electric sliders, bidirectional telescopic rods, and locking rods, multiple main jacking cylinders and concrete pipes are moved a certain distance. Then, all electric sliders are locked in position. The multiple main jacking cylinders are then extended synchronously, thereby driving the limiting and pushing mechanism to push the concrete pipe, thus ensuring stability during pushing. The extension shaft of the main jacking cylinder is supported by a support plate and the ball bearings on it, ensuring the stability of the multi-stage extension and retraction process of the main jacking cylinder and preventing the support force from becoming unstable when the extension distance is too long to the designated position.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1 This invention provides a technical solution: a long-distance pipe jacking device for municipal sewage concrete pipes, including a mounting base 1, a main jacking cylinder 2, an extension and moving mechanism 3, and a limiting and pushing mechanism 4. The mounting base 1 is set on a wall, and the extension and moving mechanism 3 is slidably mounted on the mounting base 1. Multiple main jacking cylinders 2 are evenly installed on the left end of the extension and moving mechanism 3. The main jacking cylinders 2 are multi-stage telescopic cylinders, and the telescopic ends of the main jacking cylinders 2 are all connected to the limiting and pushing mechanism 4. First, the main jacking cylinders 2 move a certain distance to move the limiting and pushing mechanism 4 into the concrete pipe. Then, the extension and moving mechanism 3 drives the limiting and pushing mechanism 4 and the main jacking cylinders 2 to move according to the required pushing distance. Finally, the main jacking cylinders 2 telescopically drive the limiting and pushing mechanism 4 to move, thereby pushing the concrete pipe forward.

[0029] Please see Figure 8 In this embodiment, the mounting base 1 includes a main board 11, which is fixedly mounted on the wall. Side support plates 12 are symmetrically mounted on the rear and lower sides of the end face away from the wall of the main board 11. The side support plates 12 are fixedly mounted to the wall, and the two side support plates 12 are connected by multiple vertical connecting rods 13.

[0030] Please see Figure 2 , Figure 3 In this embodiment, the extension and moving mechanism 3 includes a displacement seat 31, which is mounted on the mounting base 1. Sliding grooves are provided on the side support plates 12. Electric sliders 32 are installed at corresponding positions on the displacement seat 31 and the sliding grooves. The electric sliders 32 are slidably disposed in the sliding grooves. Positioning holes 33 are provided at the positions of the vertical connecting rods 13. Connecting grooves are provided on the electric sliders 32. A cavity is provided inside the vertical connecting rods 13, and a locking member 34 is provided inside the cavity to stably fix the displacement seat 31 after displacement. The locking member 34 includes a bidirectional telescopic rod 341, which is installed inside the cavity. A locking rod 342 is installed at the telescopic end of the bidirectional telescopic rod 341. During operation, the electric slider 32 drives the displacement seat 31 and the main top cylinder 2 to move in position. When the electric slider 32 moves to the positioning hole 33 at the required distance, the bidirectional telescopic rod 341 is activated to drive the locking rod 342 to insert into the positioning hole 33 and the docking groove, thereby locking all the electric sliders 32 in position and ensuring stability during pushing.

[0031] Please see Figure 5 , Figure 6 , Figure 7 In this embodiment, the limiting and pushing mechanism 4 includes a disc abutment 41. The right end face of the disc abutment 41 is connected to the telescopic end of the main top cylinder 2. A positioning unit 42 for limiting and supporting the inner wall of the concrete pipe is installed in the middle of the left end face of the disc abutment 41. Multiple sets of limiting units 43 for clamping and limiting the outer wall of the concrete pipe are evenly arranged on the left end face of the disc abutment 41 near the outer wall.

[0032] The positioning unit 42 includes a cylindrical block 421, which is installed in the middle of the left end face of the disc abutment plate 41. Grooves are formed on the outer wall of the cylindrical block 421, and rubber strips 422 are installed in each groove. A guide block 423 is installed on the left end face of the cylindrical block 421. The guide block 423 has a frustum structure and its outer wall is uniformly fitted with ball bearings. During operation, the main hydraulic cylinder 2 moves a certain distance, causing the disc abutment plate 41 to move and contact the end face of the concrete pipe. Simultaneously, the guide block 423 enters the concrete pipe. Due to the structure of the guide block 423 and the cooperation of the ball bearings, the concrete pipe is kept centered, preventing tilting. Then, the cylindrical block 421 enters the concrete pipe and abuts against its inner wall, ensuring stability and accuracy during pushing. At the same time, the limiting unit 43 moves to the outer wall position of the concrete pipe to limit and fix it.

[0033] Please see Figure 1 , Figure 7 In this embodiment, the limiting unit 43 includes connecting rods 431 symmetrically installed on the left end face of the disc abutment plate 41. Multiple round shafts 432 are evenly installed between the two connecting rods 431. The outer walls of the round shafts 432 are rotatably mounted with outer abutment plates 433 by torsion springs. The side of the outer abutment plate 433 near the positioning unit 42 has an arc structure. The end of the outer abutment plate 433 away from the positioning unit 42 is connected by a steel rope 434. The other end of the steel rope 434 is connected to the output end of the forward and reverse motor 435. The forward and reverse motor 435 is embedded in the middle of the right end face of the disc abutment plate 41. During operation, before the limiting unit 43 moves towards the outer wall of the concrete pipe, the forward and reverse motor 435 winds up the steel rope 434. The steel rope 434 and the torsion spring work together to rotate the outer abutment plate 433 to a horizontal position, so that it will not come into contact with the end face of the concrete pipe during movement. When the outer abutment plate 433 moves to the designated position, the forward and reverse motor 435 unwinds the steel rope 434, and the outer abutment plate 433 rotates to a vertical position and comes into contact with the outer wall of the concrete pipe for limiting. By limiting the inner and outer walls of the concrete pipe, the stability and linear movement of the concrete pipe can be ensured during pushing.

[0034] The outer wall of the disc abutment 41 and the corresponding position of the steel rope 434 are provided with notches. A rotating roller 411 is rotatably installed at the notch position. The steel rope 434 is in contact with the outer wall of the rotating roller 411. The rotating roller 411 rotates and transmits the steel rope 434, which reduces the friction of the steel rope 434 and improves the smoothness of the movement of the steel rope 434.

[0035] Please see Figure 1 , Figure 4 In this embodiment, fixed rods 111 are evenly installed on the left end face of the main board 11 near the outer wall. The left end face of each fixed rod 111 is connected to a supporting circular plate 112. A circular hole is provided on the supporting circular plate 112 at a position corresponding to the main top cylinder 2. Ball bearings are installed on the inner wall of each circular hole, and the diameter of the circular hole corresponds to the secondary extension diameter of the main top cylinder 2. During operation, when the main top cylinder 2 extends and pushes, the supporting circular plate 112 and the ball bearings thereon support the extension shaft of the main top cylinder 2, ensuring the stability of the multi-stage extension process of the main top cylinder 2.

[0036] In actual operation, the main hydraulic cylinder 2 moves a certain distance, causing the disc abutment plate 41 to move and contact the end face of the concrete pipe. Simultaneously, the guide block 423 enters the concrete pipe. Due to the structure of the guide block 423 and the ball bearing mechanism, the concrete pipe is centered, preventing tilting. Then, the cylindrical block 421 enters the concrete pipe and abuts against its inner wall, ensuring stability and accuracy during pushing. At the same time, the limiting unit 43 moves to the outer wall of the concrete pipe. Before the limiting unit 43 moves towards the outer wall, the forward / reverse motor 435 winds up the steel rope 434. The steel rope 434 and the torsion spring work together to rotate the outer abutment plate 433 to a horizontal position, preventing contact with the end face of the concrete pipe during movement. When the outer abutment plate 433 reaches the designated position, the forward / reverse motor 435 unwinds the steel rope 434, causing the outer abutment plate 433 to rotate to a vertical position and contact the end face of the concrete pipe. The outer wall of the concrete pipe is abutted and limited. By coordinating the limiting of the inner and outer walls of the concrete pipe, the stability and linear movement of the concrete pipe can be ensured during pushing. Then, the electric slider 32 drives the displacement seat 31 and the main top cylinder 2 to move in position. When the electric slider 32 moves to the positioning hole 33 at the required distance, the bidirectional telescopic rod 341 is activated, which drives the locking rod 342 to insert into the positioning hole 33 and the docking groove, thereby locking all the electric sliders 32 in position to ensure stability during continued pushing. Multiple main top cylinders 2 extend synchronously, thereby driving the limiting and pushing mechanism 4 to push the concrete pipe. The extension shaft of the main top cylinder 2 is supported by the support circular plate 112 and the ball bearings set on it, ensuring the stability of the multi-stage extension and contraction process of the main top cylinder 2 and preventing the support force from becoming unstable when the extension distance is too long to the designated position.
