Description

Technical Field

[0001] This utility model relates to the field of pile foundation repair technology, specifically to a sealing device and a pile foundation repair robot. Background Technology

[0002] Sleeve-type pile foundation repair robots are important equipment for cleaning and repairing pile foundations. Creating a stable and clean sleeve-type working environment for the robot is essential for ensuring efficient and precise operation during pile foundation cleaning and repair.

[0003] Existing sleeve-type pile foundation repair robots primarily rely on simple sealing strips or plugs to create a stable working environment. For example, the "bridge pile repair robot" disclosed in Chinese utility model patent CN211948024U has a main unit consisting of a frame and a plug, with the plug formed at one end of the frame. This plug has two main drawbacks: firstly, the fit between the plug and the pile is fixed and cannot be adjusted. Too small a gap can lead to installation difficulties, while too large a gap can affect the sealing effect. Secondly, this simple sealing method is prone to failure under complex stress conditions such as mud and water impacts during dynamic operation of the sleeve-type robot. It cannot reliably and stably block contaminants, affecting the robot's operational accuracy and efficiency, and consequently making it difficult to guarantee the quality of cleaning and repair. Utility Model Content

[0004] In view of this, the present invention provides a sealing device and a pile foundation repair robot, which can solve the technical problem that the poor sealing effect of the existing sleeve-type pile foundation repair robot leads to poor robot operation accuracy, and thus cannot guarantee the quality of cleaning and repair.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a sealing device, comprising: The main body is a ring structure for fitting and installing with the sleeve of the robot, and the inner side of the main body has a placement groove; At least one inflatable sealing strip is disposed in the placement groove, and the inflatable sealing strip is capable of expanding after inflation to seal the body; At least one brush assembly is disposed on the body and located on the side surface of the body facing the impact of the water flow.

[0006] In some embodiments, at least one pressure sensor is further included, which corresponds to the inflatable sealing strip. The pressure sensor is disposed on the body and connected to the inflatable sealing strip for real-time monitoring of its internal pressure.

[0007] In some embodiments, the main body is composed of multiple arc-shaped units spliced ​​together, and the inner surfaces of the multiple arc-shaped units are connected to form the placement groove.

[0008] In some embodiments, each of the arc-shaped units is provided with an inflation port that communicates with the inflation sealing strip.

[0009] In some embodiments, a water-swellable sealing sheet is provided at the splicing joint of each two adjacent arc-shaped units.

[0010] In some embodiments, the brush assembly includes an annular base and bristles, the annular base being fixed to the body, one end of the bristles being fixed to the annular base, and the other end of the bristles forming a contour for adaptation to the pile foundation.

[0011] In some embodiments, the annular base includes an L-shaped substrate and a fixing strip. The L-shaped substrate is fixed to the main body, and the fixing strip is installed on the inner side of the L-shaped substrate. The fixing strip is used to fix the bristles.

[0012] In some embodiments, the brush assembly is misaligned with the seam of the body.

[0013] In some embodiments, the body has a plurality of first mounting holes and second mounting holes, the plurality of first mounting holes being used for connection with the sleeve, and the plurality of second mounting holes being used for mounting the brush assembly.

[0014] Secondly, this utility model also provides a pile foundation repair robot, including a sleeve and the sealing device described in the first aspect of this utility model, wherein the sealing device is installed on the sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model mainly include: This invention provides a sealing device for sealing a sleeve-type pile foundation robot. By setting an inflatable sealing strip in a placement groove on the inner side of the main body, the device can seal the inside and outside of the main body after inflation, providing a stable and clean sleeve working environment for the robot's cleaning and repair operations. Furthermore, the sealing method of this invention allows for adjustment of the gap by controlling the inflation amount of the sealing strip according to the pile foundation diameter, avoiding problems such as installation difficulties due to excessively small gaps or sealing effects due to excessively large gaps. In addition, by setting a brush assembly on the side of the main body facing the water flow impact, this invention can effectively block the impact of mud, water, and debris on the device, reducing the risk of leakage, improving the robot's operating accuracy and efficiency, and thus ensuring the quality of pile foundation cleaning and repair.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] like Figures 1-2 As shown, this utility model provides a sealing device, including a main body 1, at least one inflatable sealing strip 2, and at least one brush assembly 3. The main body 1 has an annular structure for fitting and installing with a robot's sleeve. The inner side of the main body 1 has a placement groove 11. The inflatable sealing strip 2 is disposed in the placement groove 11 and can expand after inflation to seal the main body 1. The brush assembly 3 is disposed on the main body 1 and is located on the side surface of the main body 1 facing the impact of water flow.

[0020] This invention provides a sealing device for sealing a sleeve-type pile foundation robot. By setting an inflatable sealing strip 2 in the placement groove 11 inside the main body 1, the inflatable sealing strip 2 can seal the inside and outside of the main body 1 after inflation, providing a stable and clean sleeve working environment for the robot's cleaning and repair operations. The above-mentioned sealing method of this invention can adjust the gap between the inflatable sealing strip 2 and the pile foundation according to the diameter of the pile foundation by controlling the inflation amount, so as to avoid the problems of installation difficulties due to too small a gap and the sealing effect being affected by too large a gap. In addition, by setting a brush assembly 3 on the side of the main body 1 facing the water flow impact, this invention can effectively block the impact of mud, water, debris and other objects on the device, reduce the risk of device leakage, improve the robot's working accuracy and efficiency, and thus ensure the quality of pile foundation cleaning and repair.

[0021] It is understood that the inflatable sealing strip 2 is connected to an external air source to supply it with air.

[0022] In one embodiment, the inflatable sealing strip 2 is made of an elastic material (such as modified rubber) that is wear-resistant, high-pressure resistant and suitable for the pile foundation working environment (resistant to mud and water, corrosion resistant). After inflation, it forms a flexible sealing barrier, effectively blocking the penetration of liquids and debris, and protecting the internal working environment.

[0023] In one embodiment, the sealing device further includes at least one air pressure sensor 4, which corresponds to the inflatable sealing strip 2. The air pressure sensor 4 is disposed on the main body 1 and connected to the inflatable sealing strip 2, and is used to monitor its internal air pressure in real time.

[0024] In practical use, the air pressure sensor 4 is electrically connected to the robot's control system for unified and coordinated control. When the sealing strip experiences abnormal air pressure due to wear, leakage, or other reasons (such as an air pressure drop exceeding a threshold), a timely feedback signal can be provided, allowing the control system to take measures such as pressure replenishment and early warning to ensure sealing reliability.

[0025] In one embodiment, the main body 1 is composed of multiple arc-shaped units 12 spliced ​​together, and the inner surfaces of the multiple arc-shaped units 12 are connected to form the placement groove 11.

[0026] In one embodiment, each of the arc-shaped units 12 is provided with an inflation port that communicates with the inflation sealing strip 2.

[0027] In one embodiment, a water-swellable sealing sheet is provided at the splicing joint of each two adjacent arc-shaped units 12.

[0028] In one embodiment, the brush assembly 3 includes an annular base 31 and bristles 32. The annular base 31 is fixed to the main body 1, one end of the bristles 32 is fixed to the annular base 31, and the other end of the bristles 32 forms a contour for adaptation to the pile foundation.

[0029] In one embodiment, the bristles 32 are made of a wear-resistant and elastic material (such as nylon blended fibers). In addition to blocking debris and mud from outside the sleeve, the elastic structure of the bristles 32 can generate deformation buffer when water flows, reducing the force of water directly impacting the inflatable sealing strip, helping to disperse the pressure in the sealing area, reducing the risk of leakage caused by water flow impact, and synergistically improving the sealing effect.

[0030] In one embodiment, the annular base 31 includes an L-shaped base plate 311 and a fixing strip 312. The L-shaped base plate 311 is fixed to the main body 1, and the fixing strip 312 is installed on the inner side of the L-shaped base plate 311. The fixing strip 312 is used to fix the bristles 32.

[0031] In one embodiment, the brush assembly 3 is staggered with the seam of the main body 1.

[0032] In one embodiment, the main body 1 has a plurality of first mounting holes and second mounting holes, the plurality of first mounting holes being used for connection with the sleeve, and the plurality of second mounting holes being used for mounting the brush assembly 3.

[0033] The working principle of the sealing device provided by this utility model is as follows: During operation, the robot carries this sealing device into the pile foundation work area. The bristles 32 first contact the outer wall of the pile foundation, using elastic deformation to buffer the impact of water flow, disperse pressure, and simultaneously block debris. Upon reaching the working position, the inflatable sealing strip 2 inflates to a set pressure, tightly fitting the sleeve and the robot to form the main seal. While the inflatable sealing strip 2 begins inflation, the air pressure sensor 4 monitors the air pressure in real time, providing feedback on the sealing status. If the air pressure is abnormal, it triggers pressure replenishment or an alarm, continuously ensuring a stable sealing environment and assisting the robot in carrying out cleaning and repair operations. After the operation is completed, the inflatable sealing strip 2 is deflated, and the robot exits the work area.

[0034] In addition, this utility model also provides a pile foundation repair robot, including a sleeve and the sealing device provided above, wherein the sealing device is installed on the sleeve.

[0035] In summary, the sealing device provided by this utility model has a brush assembly 3 that serves to block debris, buffer water flow, and disperse pressure. Combined with the flexible seal of the inflatable sealing strip 2, it forms a double guarantee, effectively blocking mud, water, and debris. It is suitable for the complex environment of pile foundations, reduces the risk of leakage, and improves the stability of the robot's working environment. The air pressure sensor 4 can perform real-time monitoring, promptly detect the risk of seal failure, facilitate proactive intervention, reduce the probability of operational failure, and ensure the continuity of operation.

[0036] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
