Description

Technical Field

[0001] The invention relates to the technical field of special-shaped pipeline repair, in particular to a non-excavation repair follow-up winding machine for special-shaped pipelines. Background Art

[0002] Urban drainage pipes are called the "underground lifeline" of the city, and they are responsible for the important tasks of urban sewage and waterlogging. As the scale of urban construction in my country continues to expand, the maintenance and repair of drainage pipes has received more and more attention. The traditional method of pipeline repair is to replace new pipes by excavation, which results in a huge amount of engineering work and high costs. It is also impossible to complete the project in a short time, and it will lead to traffic jams and environmental pollution, which are difficult for modern urban construction to bear. Trenchless repair technology is an engineering technology that uses trenchless or micro-excavation technology to repair damaged underground pipes partially or as a whole. Compared with the traditional excavation and replacement technology, it has great advantages such as no impact on traffic, reduced environmental pollution, short construction time, fewer construction personnel, high safety, and low comprehensive cost. The introduction of trenchless repair technology has greatly increased the possibility of upgrading urban underground pipelines. The more mature trenchless repair methods in China now mainly include soft lining method, interlacing method, broken pipe method, reduced diameter lining method, spiral winding method, pipe segment assembly method and some local repair methods. As for the spiral winding method, my country currently has independently developed winding devices and grouting devices for circular pipes. However, the research on equipment for other special-shaped pipes, especially follow-up mobile winding machines, is still in the exploratory stage.

[0003] Although the winding machine body in the prior art can well fill the pipe with plastic tape to repair the pipe, the environment inside the pipe is harsh. The winding machine is prone to rust when working in a humid place in the pipe, which causes greater wear and tear on the winding machine, reduces its service life, and requires frequent maintenance and replacement, which is not enough to save economic costs. Manually applying rust inhibitors to the device is troublesome and requires frequent application, which increases the workload of the staff. At the same time, when filling different pipes, different tracks need to be spliced, but the splicing of tracks in the prior art is all done by welding, which results in the track being suitable for only one type of pipe. Although some prior arts are fixed by bolts, more bolts are used to splice the tracks, which makes the track installation and disassembly difficult and inconvenient for staff to operate.

[0004] To this end, we propose a trenchless repair follow-up winding machine for special-shaped pipes to solve the above problems. Summary of the invention

[0024] A liquid storage chamber 13 is provided at a portion of the straight rail 3 near the plurality of inner grooves 7. The liquid storage chamber 13 is also provided with anti-rust liquid. The plurality of liquid storage chambers 13 are sealedly connected with the plurality of corresponding inner grooves 7 through a connecting pipe 14. A one-way valve 15 is provided in the connecting pipe 14. A one-way valve 28 is provided in the liquid delivery pipe 11. The plurality of liquid storage chambers 13 are connected through a liquid inlet pipe 16.

[0025] The straight rail 3 has an inner chamber 18 at both ends, and a threaded rod 25 is rotatably connected in each inner chamber 18. The plurality of threaded rods 25 penetrate the inner chamber 18 and are rotatably connected to the inner chamber 18 by threads.

There is no need for staff to frequently check the winding machine. The main body is easy to maintain and use; when the pressure roller 6 leaves the arc block 10, the reset spring 8 begins to reset, and the piston block 9 resets to its original position, so the pressure in the inner tank 7 is reduced, and the anti-rust liquid in the liquid storage chamber 13 enters the inner tank 7 through the one-way valve 15, so as to replenish the anti-rust liquid in the inner tank 7. After using it for a period of time, the staff can replenish the anti-rust liquid into the liquid storage chamber 13 through the valve 17. Therefore, when the winding machine body 1 is subjected to anti-rust treatment, manual operation is not required, and the whole device has a high degree of automation, which is convenient for people to use.
