Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a pipeline cleaning device and a carrying device thereof. Background Art

[0002] To prevent ground subsidence during shield tunneling, grouting is typically performed behind the segment walls to fill excavated voids. To ensure the grout's cohesive strength, grouting blocks are installed at the end of the grouting pipeline to thoroughly mix the two-liquid slurry. However, the mixed two-liquid slurry easily coagulates and clogs the grouting blocks.

[0003] When the grouting block is blocked, it is usually necessary to stop the excavation construction, dismantle the blocked grouting block pipeline, and replace the new grouting block pipeline, which consumes a lot of manpower and material resources and affects the excavation efficiency. In recent years, with the development of science and technology, research on pipeline cleaning has gradually emerged. Most of them use lasers or mechanical extrusion to clean the blockages in the pipeline. For example, the Chinese patent application number 202210357061.8 discloses a pipeline cleaning device. Through the coordinated work of laser cleaning, foreign matter extraction, recovery device and cleaning device, the inner wall of the pipeline is cleaned and dirt is recovered. However, in pipelines with special shapes or materials, the effect of laser cleaning may be limited. The Chinese patent application number 202310816013.5 discloses a pipe wall laser cleaning robot. The robot independently controls the crawling and rotating cleaning functions by introducing a telescopic mechanism to optimize the cleaning process and improve efficiency. However, the telescopic mechanism and rotating cleaning head of the robot need to be precisely controlled to avoid damaging the robot or the pipeline. The Chinese patent application number 202111306444.4 discloses a shield machine pipeline cleaning robot, which improves the efficiency of breaking the blocking material in the main slurry discharge pipe by supporting the main body, the coordination of the crushing assembly and the sealing head, and the fixing position of the tightening device, thereby avoiding time-consuming and labor-intensive cleaning work. However, the tightening device of the robot needs to adapt to pipes of different diameters and may need to be adjusted to adapt to specific sizes. When there are blockages of complex shapes in the pipe, the cleaning efficiency may be reduced. In summary, a single pipeline cleaning device is difficult to adapt to the complex and changeable pipeline blockage environment and cannot effectively clean the pipeline. Therefore, it is extremely necessary to design a shield grouting pipeline blockage cleaning device carrying platform, and to select different cleaning devices by detecting the pipeline blockage situation.

[0026] In this embodiment, as a preferred solution, the airbag-type propping mechanism 2 includes a plurality of inflatable airbags 2-1 evenly distributed around the periphery of the platform body 1; that is, the inflatable airbags are arranged in blocks around the platform body, with the side closest to the platform body fixed to the platform body. In the non-operating state, that is, during normal movement, the inflatable airbags shrink and adhere to the platform body. During cleaning, to eliminate the supporting reaction force caused by the cleaning device, the inflatable airbags are inflated, realizing an adaptive cleaning device for different diameters and different types of blockages in the pipeline to be cleaned; the platform performs a stable cleaning function in the pipeline. The charging and discharging ports of the inflatable airbags 2-1 are connected to the charging and discharging device, such as an integrated charging and discharging pump, through a pipeline.

[0027] As a preferred solution, Figure 2As shown, the connection mechanism on the front face of the platform body 1 includes a front fixing hole 3 and / or a front fixing buckle. The front fixing holes 3 are preferably threaded holes, with a number of 1 to 12. These are threaded holes used to fix different types of exploration devices, such as: fill lights, manipulators, and gas detectors.

Preferably, the front face of the platform body 1 is also provided with an image acquisition device 4; the image acquisition device 4 is preferably a camera, with at least one camera, used to observe the internal conditions of the pipeline.

[0028] As a preferred solution, Figure 3 As shown, the connection mechanism on the rear end face of the platform body 1 in this embodiment includes a rear fixing hole 7 and / or a rear fixing buckle.

External lines only need to be connected here to meet the power supply and signal transmission requirements of different positions.

[0029] like Figure 4 As shown, Example 2 is a platform for carrying a device for cleaning a pipe blockage, which is further optimized on the basis of Example 1. In this embodiment, a receiving groove 10 is provided at the bottom of the platform body 1, and the retractable drive wheel mechanism 5 can be retracted into the receiving groove 10. The number of receiving grooves 10 can be set as needed. In this embodiment, four receiving grooves 10 are taken as an example, and four retractable drive wheel mechanisms 5 are correspondingly provided. The retractable drive wheel mechanisms 5 correspond to the receiving grooves one by one, and the depth of the receiving groove is based on being able to completely accommodate the retractable drive wheel mechanisms 5. The four receiving grooves 10 and the corresponding four retractable drive wheel mechanisms 5 are distributed at the bottom of the platform body 1; the retractable drive wheel mechanism 5 is used to drive the platform for cleaning a pipe blockage.

[0030] Specifically, if Figure 6 、 7 As shown, the retractable drive wheel mechanism 5 described in this embodiment includes an electric drive wheel 5-1, which is a running wheel driven by a motor, to achieve flexible movement of the platform. The electric drive wheel 5-1 is hinged to the bottom of the platform body 1 through a support frame 5-3; that is, one end of the support frame 5-3 is fixed in the storage groove 10 under the platform body through a pin, and the other end is hinged to the electric drive wheel. A retractable drive member is connected between the support frame 5-3 and the platform body 1. Under the action of the retractable drive member, the support frame 5-3 drives the electric drive wheel 5-1 to be retracted or not. The retractable drive member plays the role of fixing the electric drive wheel 5-1 and assisting in changing its contracted or extended state.

[0031] The folding and retracting drive can be a telescopic drive such as a pneumatic or hydraulic cylinder, or a worm gear. In this preferred embodiment, the folding and retracting drive comprises a motor 5-6 embedded in the bottom of the platform body 1 and a worm 5-4 rotatably mounted at the bottom of the platform body 1.

To prevent ground subsidence during tunneling, shield machines typically inject grout behind the segment walls to fill the excavated gaps. To ensure the slurry's coagulation strength, grouting blocks are installed at the end of the grouting pipeline to fully mix the two-liquid slurry. However, after mixing, the two-liquid slurry easily coagulates and clogs the grouting blocks. The aforementioned pipe cleaning device can adapt to complex and changing pipeline blockage environments and efficiently clean the pipeline.

[0033] The specific working process is as follows: the shield grouting pipeline blockage cleaning device carrying platform is equipped with electric drive wheels to enable the carrying platform to move freely in the pipeline; the camera can be used to observe and judge the appropriate cleaning device and judge whether the cleaning is in place during the cleaning process; the fixed installation of different cleaning devices is achieved through the fixed seat, front fixing hole and rear fixing hole to adapt to the complex and changeable pipeline blockage environment and complete the pipeline cleaning work efficiently; inflatable airbags are set around it to achieve the function of adaptively fixing the carrying platform according to the pipeline size to eliminate the support reaction force brought by the cleaning device. When the carrying platform is moving, the inflatable airbag shrinks and attaches to the platform body. At this time, the worm moving block stays at the front end of the worm and the electric drive wheel extends; when cleaning work is being carried out, the inflatable airbag is inflated to achieve the function of adaptively fixing the shield grouting pipeline blockage cleaning device carrying platform in the pipeline. At this time, the worm moving block moves to the rear end of the worm and the electric drive wheel retracts.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
