Description

Technical Field

[0001] This utility model relates to the field of pipeline burst repair technology, and in particular to a pipeline positioning and adjustment device for a pipeline burst repair robot. Background Technology

[0002] Sewage pipe corridors are typically quite long, formed by connecting multiple pipes end to end with connectors. During long-term operation, leaks may occur at the connection points between two pipes. Due to the length of the corridor and the large number and density of pipes, current inspections and maintenance are generally carried out by robots, as humans cannot operate within them.

[0003] However, currently, after the robot cuts open the pipe at the location of the leak, the axes of the pipes at both ends may not be on the same central axis. This may cause the pipes at both ends to be unable to be smoothly inserted into the replacement pipe section when it is reconnected, which will affect the subsequent installation of new pipes.

[0004] Therefore, it is necessary to propose a pipe positioning and adjustment device for a pipe burst repair robot to solve the problems mentioned above. Utility Model Content

[0007] By adopting the above technical solution, the rotation of the bidirectional screw drives clamping parts a and b to move in opposite directions, thereby achieving the purpose of clamping the pipe. Through the extension and retraction of the piston rod of the electric telescopic rod, pipes a and b can be pushed to the middle pipe section. At the same time, the fixing blocks on both sides of the fixed frame will roll in the corresponding positioning groove, thereby enabling linear limiting activities of the fixed frame, clamping parts a, clamping parts b, pipes a and b.

[0008] In a preferred embodiment, clamping member a and clamping member b are respectively threaded to both ends of the outer side of the bidirectional lead screw, and both clamping member a and clamping member b are slidably connected to the inner wall of the fixed frame.

[0011] By adopting the above technical solution and setting up the replacement pipe section, one end of pipe a and pipe b can be connected and inserted into the replacement pipe section.

[0012] In a preferred embodiment, electric telescopic rods are fixedly installed on both sides of the mounting frame, and the piston rods of the electric telescopic rods extend into the interior of the mounting frame and are fixedly connected to the corresponding fixed frames.

[0013] By adopting the above technical solution, the piston rod of the electric telescopic rod can be extended and retracted to push the corresponding fixed frame to move, thereby facilitating the connection of the two pipe sections.

[0017] By adopting the above technical solution and using the installation components, the pipeline positioning and adjustment device can be installed on the maintenance robot.

[0018] In a preferred embodiment, a drive motor is fixedly installed at the bottom of each fixed frame, and the output shaft of the drive motor extends into the interior of the fixed frame and is fixedly connected to a bidirectional lead screw.

[0019] By adopting the above technical solution, the rotation of the output shaft of the drive motor can provide a power source for the bidirectional lead screw.

[0020] In a preferred embodiment, both pipe a and pipe b are fitted with clamps on their outer sides, and both pipe a and pipe b are installed inside the pipe support by means of clamps.

[0021] By adopting the above technical solution and using clamps, pipes a and b can be installed in the pipe support.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Reference Figure 1-5 The pipe positioning and adjustment device of the pipe burst repair robot includes a pipe support 1. One end of the pipe support 1 has a pipe a2, and the other end has a pipe b16. The pipe support 1 has a mounting frame 3 inside. Both ends of the inner wall of the mounting frame 3 are slidably connected to a fixed frame 6. A bidirectional screw 7 is rotatably connected inside each fixed frame 6. Clamping parts a8 and b9 are provided on the outer sides of each bidirectional screw 7. Fixing blocks 13 are fixedly connected to both sides of the fixed frame 6. Positioning grooves 14 are provided on both sides of the mounting frame 3. Positioning rollers 15 are fixedly connected to the side of each fixed block 13 closest to the mounting frame 3. When the repair robot cuts open the pipe at the leak location, it can use the bidirectional screw 7... The rotation causes clamping parts a8 and b9 to move in opposite directions, thereby achieving the purpose of clamping the pipe. Then, through the extension and retraction of the piston rod of the electric telescopic rod 5, pipes a2 and b16 can be pushed to the middle replacement pipe section 11. At the same time, the fixing blocks 13 on both sides of the fixing frame 6 will roll in the corresponding positioning grooves 14, thereby enabling the fixing frame 6, clamping parts a8 and b9, pipes a2 and b16 to perform linear limiting activities. Through the use of the replacement pipe section 11, the two pipe sections a2 and b16 can be connected together, thereby enabling the axis of the two pipe sections to be automatically adjusted to the same central axis, so as to reduce the impact on the subsequent installation of new pipes.

[0033] Specifically, clamping parts a8 and b9 are threaded to both ends of the outer side of the bidirectional screw 7. Both clamping parts a8 and b9 are slidably connected to the inner wall of the fixed frame 6, which can ensure that clamping parts a8 and b9 can operate stably. A clamping part 12 is provided in the middle of the mounting frame 3. Through the setting of the pipe patch 11, one end of pipe a2 and pipe b16 can be inserted into the pipe patch 11. The pipe patch 11 is provided inside the clamping part 12. The pipe patch 11 is connected to the outer side of the mounting frame 3 through the clamping part 12. Electric telescopic rods 5 are fixedly installed on both sides of the mounting frame 3. Through the extension and retraction of the piston rod of the electric telescopic rod 5, the corresponding fixed frame 6 can be moved, which facilitates the connection of the two pipe sections. The piston rods of the electric telescopic rods 5 extend into the interior of the mounting frame 3 and are fixedly connected to the corresponding fixed frame 6.

[0034] Specifically, rubber pads are fixedly connected to the inner walls of clamping parts a8 and b9, and hot melt adhesive is applied to the inner wall of the pipe section 11. The use of hot melt adhesive can ensure the stability of pipe a2 and pipe b16 after docking. The positioning rollers 15 are engaged with the corresponding positioning grooves 14. Two mounting parts 4 are fixedly connected to the side of the mounting frame 3 away from the fixed frame 6. The pipe positioning and adjustment device can be installed on the maintenance robot through the use of mounting parts 4. The bottom of the fixed frame 6 is fixedly installed with drive motors 10. The output shaft of the drive motor 10 extends into the interior of the fixed frame 6 and is fixedly connected to the bidirectional lead screw 7. The rotation of the output shaft of the drive motor 10 can provide a power source for the bidirectional lead screw 7. Clamps are fitted on the outer sides of pipe a2 and pipe b16. Pipe a2 and pipe b16 are installed inside the pipe support 1 through clamps.

[0035] Working principle: First, the operator can install the pipe positioning and adjustment device on the maintenance robot using mounting part 4. Then, the operator controls the maintenance robot to move to the pipe repair point and uses the cutting equipment on the robot to cut the two leaking sections of the pipe. The clamps at pipes a2 and b16 are then loosened. After the maintenance robot cuts the leaking section, the drive motor 10 is started. The rotation of the output shaft of the drive motor 10 drives the rotation of the bidirectional lead screw 7, causing clamping parts a8 and b9 to move in opposite directions, thus achieving the purpose of clamping the pipe. Then, the piston rod of the electric telescopic rod 5 extends and retracts... It can push pipes a2 and b16 to move towards the middle pipe section 11. At the same time, the fixing blocks 13 on both sides of the fixing frame 6 will roll in the corresponding positioning grooves 14, thereby enabling the fixing frame 6, clamp a8, clamp b9, pipe a2 and pipe b16 to perform linear limiting activities. Through the use of the pipe section 11, the two pipe sections a2 and b16 can be connected together, so that the axis of the two pipe sections can be automatically adjusted to the same central axis. With the setting of the pipe section 11, one end of pipe a2 and pipe b16 can be inserted into the pipe section 11 to make the pipe connection more secure.
