Description

Technical Field

[0001] This invention belongs to the field of anchor cable pretreatment in hydropower engineering, specifically relating to an equipment system and method for on-site peeling and cleaning of unbonded prestressed anchor cables. Background Technology

[0002] With the rapid development and continuous innovation of modern engineering technology, the construction scale of major national projects has also expanded significantly. This has not only driven the continuous growth of support engineering scale but also gradually increased the technical difficulty and challenges faced. Against this backdrop, prestressed anchor cables, with their unique advantage of being able to freely adjust prestress according to rock mass deformation, thus significantly improving anchoring effect, have gradually become an indispensable and important means in various engineering reinforcement processes. They are particularly widely used in tunnel engineering, water conservancy and hydropower engineering, and mine support. In recent years, with the continuous improvement of engineering construction standards, unbonded prestressed anchor cable technology has also made considerable progress. To improve the durability of anchor cables, PVC sleeves filled with anti-rust grease are widely used in engineering to protect the steel strands. Simultaneously, during anchor cable tensioning, the front end needs to have the PVC sleeve removed and oily substances cleaned to facilitate anchor cable construction. However, traditional processes typically use manual cleaning methods, which cannot efficiently clean the sleeves and oily substances. Therefore, the treatment of unbonded prestressed anchor cable sleeves and anti-rust grease has become a pressing technical problem. Many shortcomings exist in traditional cleaning methods. These shortcomings are mainly reflected in the fact that the methods for cleaning anchor cable rust-preventive grease rely heavily on manual operation, which is not only inefficient but also makes it difficult to guarantee the cleaning quality; they require a certain amount of manpower and resources, increasing construction and time costs; and manual cleaning of oily substances on anchor cables is inefficient and cannot meet the needs of large-scale engineering construction. To solve these problems, there is an urgent need for the design of on-site peeling and cleaning equipment for unbonded prestressed anchor cables.

[0003] For the stripping and cleaning of anchor cables under tension, existing technologies are slow and cannot meet large-scale demands. Traditional methods for cleaning anchor cables of anti-rust grease mainly rely on manual labor. Manual cleaning of oily substances on anchor cables is slow and limited by worker endurance, making it difficult to complete the cleaning of a large number of anchor cables in a short time. Furthermore, due to variations in manual operation and limitations of manual tools, cleaning efficiency is difficult to guarantee. The stripping quality is also poor. Existing manual cutting typically involves workers using simple tools such as knives to peel off the exposed ends of unbonded prestressed anchor cables. However, due to the dense distribution of steel strands in multi-strand anchor cables, peeling off certain areas of the strands is difficult, significantly impacting the anchoring quality. Moreover, the cleaning process is challenging. During the cleaning of anchor cable steel strands, manual separation of multiple strands is required, which is difficult and involves long cleaning sections. The steel strands also have a certain degree of resilience, increasing the difficulty for workers and reducing the quality of cleaning. Traditional cleaning methods require gasoline as an organic solvent to dissolve oily substances and a large amount of cleaning gauze, posing a significant fire hazard. Summary of the Invention

The waste liquid channel is located lower than the liquid delivery channel of the cleaning pipe, so as to realize the replacement of the organic solution in the channel.

[0007] According to some embodiments of this application, the organic solution storage chamber serves as a storage device for organic solutions, provides cleaning solutions for the cleaning channel, the storage chamber delivery channel is used for adding and recovering organic solvents, and the rotating component isolates the internal space from the outer wall of the cleaning device, enabling the structure to rotate.

The sleeve shearing blade cuts the sleeve into four parts, and the arc-shaped design is adapted to rotary cutting to reduce cutting resistance. The cleaning brush, as the main component for cleaning the anchor cable, obtains organic solution from the organic solution storage chamber through the organic solution channel at the rear to brush the anchor cable.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of 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, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0041] For ease of description, spatial relative terms can be used in the text to describe the relative positional relationship or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "upper," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device during use or operation, in addition to those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or movement change, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "on other elements or features." The term "area" is used here. Therefore, the example term "below" can include both above and below. The device may be oriented in other ways (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text will be interpreted accordingly.

[0042] like Figure 1 and Figure 11As shown, in a first aspect, this application provides an on-site peeling and cleaning equipment system for unbonded prestressed anchor cables, comprising: a cleaning pipe 11 for the middle strand; a cleaning pipe 12 for the ring strand; a waste liquid channel 13; a cleaning pipe delivery channel 14; an organic solution storage chamber 15; a storage chamber delivery channel 16; an outer wall of the cleaning device 17; a rotating component 18; an anchor cable channel 21; a sleeve cutting component 22; a fixing component 23; an anchor cable degreasing sleeve 24; an anchor cable limiting ring 31; a friction wheel 32; a first rotating motor 33; a sliding component 34; a tension spring 35; a sliding groove 36; an assembled component 41; a waste liquid recovery tank 42; a second rotating motor 43; a working handle 44; a moving wheel 45; a sleeve cutting ring 51; a sleeve shearing blade 52; a cleaning brush 53; an organic solution storage chamber 54; an organic solution channel 55; a third rotating motor 56; a propulsion handle 57; and a directional switch 58.

[0043] like Figure 2 As shown, in this embodiment, the anchor cable is placed between the anchor cable limiting rings 31. The rotating motor 33 is turned on, allowing the anchor cable to pass through the anchor cable channel 21 and partially cut the sleeve. The rotating motor 33 is then turned off, and the steel strands of this portion of the anchor cable are separated and placed in the middle strand cleaning pipe 11 and the ring strand cleaning pipe 12, respectively. The rotating motors 33 and 43 are then turned on until the required anchoring length is achieved. The rotating motors 33 and 43 are then rotated in opposite directions to re-tie the cleaned steel strands until the anchor cable is completely recovered.

[0044] Furthermore, such as Figures 3 to 4 As shown, in this embodiment, the cleaning pipes 11 and 12 for the middle strand and the ring strand are filled with organic solvent during operation. The rotation and movement of the strands dissolve oily substances in the organic solution. The inlet / outlet channel 14 and waste liquid channel 13 of the cleaning pipe serve as the inlet and outlet of the organic solution, respectively. The waste liquid channel 13 is positioned lower than the inlet / outlet channel 14, allowing for the replacement of the organic solution within the channel. The organic solution storage chamber 15 serves as a storage device for the organic solution, providing cleaning solution to the cleaning channels. The inlet / outlet channel 16 of the storage chamber is used for adding and recovering organic solvent. The rotating component 18 isolates the internal space from the outer wall 17 of the cleaning device, enabling the structure to rotate. The oily substance cleaning device can rotate to separate and bundle the seven strands of anchor cable, and complete the cleaning of oily substances from the surface of the strands within its interior.

[0045] In the technical solution of this embodiment, the high-efficiency cleaning device for oily substances on anchor cables has 7 steel strand channels inside its structure. The relative movement of the anchor cable and the organic solvent and the rotation of the device achieve the effect of high-efficiency cleaning of oily substances, improve the cleaning rate, ensure the quality of anchor cable cleaning, and realize the disassembly and remanufacturing of anchor cables. The equipment adopts a closed cleaning method to reduce the risk of fire.

[0046] Furthermore, such as Figure 5 As shown, in this embodiment, the anchor cable channel 21 transports the anchor cable and restricts its movement, completing the sleeve cutting without damaging the exposed anchor cable. The sleeve cutting component 22 is divided into upper and lower parts, with a sharp cutting end and an overall arc design. It cuts the sleeve and removes waste sleeve pieces to both ends. The fixing component 23 connects the anchor cable degreasing sleeve 24, which has oil-absorbing brushes inside to absorb liquid from the surface of the steel strand. The anchor cable sleeve peeling device efficiently cuts the anchor cable anchoring section sleeve and absorbs liquid from the surface of the steel strand during recycling, achieving a dual function of peeling and cleaning.

[0047] In the technical solution of this embodiment, the unbonded prestressed anchor cable sleeve peeling device combines the dual functions of cutting the sleeve and cleaning the anchor cable. It uses an arc-shaped cutting tool to cut the anchor cable sleeve and process the waste sleeve pieces, thereby improving cutting efficiency. At the same time, it can cut and peel the sleeve inside the anchor hole to ensure the quality of anchor cable cleaning.

[0048] Furthermore, such as Figure 6 and Figure 8 As shown, in this embodiment, the anchor cable limiting ring 31 limits the anchor cable to the friction wheel 32 and provides forward or backward power through the different directions of the two friction wheels 32. The rotating motor 33 provides power to the anchor cable propulsion component. The sliding component 34, together with the tension spring 35 and the sliding groove 36, realizes the movement of the rotating component, ensuring effective transmission of the anchor cable. The anchor cable propulsion component changes the distance between the rotating components according to the anchor cable cleaning and recycling operations, thus providing power transmission to the anchor cable.

[0049] Furthermore, such as Figure 7 As shown, in this embodiment, the prefabricated component 41 enables the installation and disassembly of the oily substance cleaning device and the anchor cable sleeve peeling device, facilitating device cleaning and storage. The waste liquid recovery tank 42 recovers the waste liquid flowing out of the waste liquid channel 13, allowing for the reuse of reusable liquids. The rotating motor 43 provides rotational power to the oily substance cleaning component. The operating handle 44 and the moving wheels 45 facilitate the movement of the device. The tensioning end peeling and cleaning equipment efficiently cleans short-distance anchor cables at the tensioning end, facilitating anchor cable tensioning operations and subsequent anchor sealing. The operating platform provides placement and operating space for the entire equipment, enabling its movement and efficient operation.

[0050] In this embodiment, the device position is adjusted based on whether the anchor cable sleeve is cut to improve anchor cable transmission efficiency. Anchor cable transmission and retrieval are completed by changing the direction of the rotating motor, further improving cleaning efficiency. Simultaneously, a movable platform and prefabricated structure design are adopted, adapting to the overall function of the device. It provides a waste liquid recovery tank, a device storage room, and dedicated installation functions, suitable for the disassembly and installation of the cleaning device and sleeve peeling device. The method is simple, facilitates equipment cleaning, improves construction quality, facilitates equipment transportation, and ensures construction safety.

[0051] Furthermore, such as Figures 9 to 11 As shown, in this embodiment, the sleeve cutting ring 51 has a frustum-shaped structure with a smaller upper diameter, used to cut into the sleeve to initially separate the sleeve from the anchor cable, facilitating sleeve cutting. The sleeve shearing blade 52 cuts the sleeve into four parts; its arc-shaped design is adapted to rotary cutting, reducing cutting resistance. The cleaning brush 53, as the main component for cleaning the anchor cable, obtains organic solution from the organic solution storage chamber 54 through the rear organic solution channel 55 to brush the anchor cable. The rotary operating system, consisting of the rotating motor 56, the push handle 57, and the direction switch 58, provides rotational power to the equipment, and the rotation direction is adjusted by the direction switch 58 to achieve efficient cleaning of the anchor cable. The tension end peeling and cleaning equipment efficiently cleans short-distance anchor cables at the tension end, facilitating anchor cable tensioning operations and subsequent anchor sealing.

[0052] Secondly, this application provides a method for using a peeling and cleaning device for the anchorage end of an unbonded prestressed anchor cable. This method utilizes multiple peeling and cleaning devices for the anchorage end of unbonded prestressed anchor cables, as described in the above embodiments, to perform anchor cable peeling and cleaning operations. The method further includes: S10. Clean the anchoring end. First, check whether the motor device and the transmission device are normal. Specifically, first check whether the motor device, including rotating motor 1 33, rotating motor 2 43 and the friction wheel 32 and sliding component 34 in the anchor cable propulsion device of the transmission device, are operating normally. Ensure that all parts of the equipment are firmly connected and that the power system is normal, so as to lay the foundation for subsequent cleaning work.

[0053] S20: Place the anchor cable between the anchor cable limiting rings 31, fixing its position to the centerline of the anchor cable channel 21. Turn on the rotating motor 33 to drive the friction wheel 32 to rotate, moving the anchor cable towards the anchor cable sleeve peeling device, allowing it to pass through the anchor cable channel 21. Use the sleeve cutting component 22 to complete partial sleeve cutting. After cutting, turn off the rotating motor 33 and manually separate the steel strands of the cut portion of the anchor cable. Place the middle bundle of steel strands in the middle bundle cleaning pipe 11, and place the surrounding six bundles of steel strands in the ring bundle cleaning pipes 12. Then, turn on the rotating motor 33 to provide power for anchor cable movement, and simultaneously turn on the rotating motor 43 to drive the oily substance cleaning device to rotate. Through rotation and movement of the steel strands, the oily substance on the surface of the steel strands dissolves in the organic solution until the required anchoring length is cleaned.

[0054] S30, after cleaning is completed, rotate motor 33 and motor 43 in opposite directions. The reverse rotation of motor 33 drives the friction wheel 32 to move in the opposite direction, pulling the cleaned steel strand back. At the same time, the reverse rotation of motor 43 causes the oily substance cleaning device to rotate in the opposite direction, re-bundling the separated steel strands until the anchor cable is completely recovered.

[0055] S40, clean the tensioning end. First, check if the motor and conveyor are functioning properly. Specifically, before cleaning the tensioning end, check if the equipment has sufficient power to ensure that the power components, such as the rotating motor 56, are working properly. Also, check if auxiliary tools, such as tools for cutting waste sleeves, are readily available. Then, fill the organic solvent storage chamber 54 through the organic solvent channel 55, ensuring that there is enough solvent in the storage chamber for subsequent cleaning operations.

[0056] S50, align the sleeve cutting ring 51 of the tension end peeling and cleaning equipment with the anchor cable sleeve, and slowly push the equipment so that the sleeve cutting ring 51 initially cuts into the inside of the sleeve, achieving initial separation of the sleeve and the anchor cable, preparing for subsequent cutting. Start the equipment switch, causing the rotating motor 3 56 to drive the equipment clockwise, while simultaneously slowly pushing the advance handle 57 to move the equipment along the anchor cable axis. During rotation, the sleeve shearing blade 52 cuts the sleeve into four parts, and the cut sleeve waste pieces are discharged through the waste piece outlet. The cut anchor cable continues to move forward, passing through the cleaning brush 53. Under the action of the equipment rotation, the cleaning brush 53 dips into the organic solvent delivered from the organic solvent storage chamber 54 through the organic solvent channel 55, performing initial cleaning of the oily substances on the anchor cable surface, dissolving the oily substances in the organic solvent, until the sleeve cutting and initial cleaning work are completed.
