Description

Technical Field

[0001] This application relates to the field of adhesive coating technology for W-steel strips, and in particular to an adhesive coating device for W-steel strips used in tunnel maintenance. Background Technology

[0002] In tunnel maintenance engineering, W-shaped steel strips are an important support material, and their surface adhesive treatment is crucial for enhancing corrosion resistance and extending service life. However, traditional adhesive application methods for W-shaped steel strips have many drawbacks and fail to meet engineering requirements. Traditional adhesive application relies heavily on manual fixing of the W-shaped steel strips, which not only results in uneven clamping force, easily leading to localized deformation of the W-shaped steel strips, but also easily causes displacement during the adhesive application process, affecting the accuracy of the adhesive application. When manually adjusting the adhesive application position and height, it is difficult to accurately adapt to different parts of the "W"-shaped structure of the W-shaped steel strip, making the operation cumbersome and inefficient.

[0003] The tools used for applying adhesive are mostly made of rigid materials, which cannot fit well into the bends and grooves of the W-shaped steel strip, resulting in missed areas and affecting the quality of the adhesive application. Furthermore, excess adhesive drips randomly during the application process, causing waste and contaminating the work platform, which in turn affects the subsequent clamping and securing effect.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problems of traditional adhesive application relying heavily on manual fixing of W-steel strips, which not only results in uneven clamping force leading to localized deformation of the W-steel strips, but also causes displacement during the adhesive application process, affecting the accuracy of the adhesive application, this application provides an adhesive application device for the surface of W-steel strips used in tunnel maintenance.

[0006] This application provides a surface adhesive coating device for W-steel strips used in tunnel maintenance, employing the following technical solution:

[0007] A surface adhesive coating device for W-steel strips used in tunnel maintenance includes a base, on both sides of which are mounted on frames. A cylinder is mounted on the frame, and the output end of the cylinder is connected to a positioning frame. A set of clamping blocks is fixed to the inner wall of the positioning frame. A housing is mounted on the side wall of the base, and a lead screw assembly is provided inside the housing. A fixing frame is mounted on the lead screw assembly, and an adhesive coating component is provided on the fixing frame.

[0008] Preferably, guide rods are symmetrically fixed on both sides of the top of the positioning frame, and the guide rods are slidably connected to the frame.

[0009] Preferably, the lead screw assembly includes a motor mounted on one side of the inner wall of the chassis, a lead screw disposed inside the chassis, and a lead screw slider that is slidably adapted to the lead screw, wherein the output end of the motor drives the lead screw.

[0010] Preferably, the bottom of the fixing frame is fixed to the top of the lead screw slider with screws, and an electric push rod is installed on the fixing frame.

[0011] Preferably, the adhesive application component includes an adhesive bin fixed to an electric push rod, adhesive application heads located on both sides of the bottom of the adhesive bin, and adhesive application brushes distributed on the adhesive application heads.

[0012] Preferably, a material pipe is connected to one side of the top of the glue box, and a collection box is fixed to the bottom of the inner wall of the fixing frame.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This application utilizes a cylinder-driven positioning frame to move, where the clamping block engages with the base slot, enhancing the limiting effect on the W-shaped steel strip. Combined with the sliding guidance of the guide rod and frame, this ensures more even clamping force, preventing localized deformation of the W-shaped steel strip. The lead screw assembly, in conjunction with an electric push rod, adjusts the height of the adhesive application component, precisely adapting to the adhesive application needs of different parts of the W-shaped steel strip and improving operational convenience. The soft nature of the adhesive brush allows it to adaptively adjust to the surface curvature when conforming to the "W"-shaped structure of the W-shaped steel strip, ensuring no dead spots in adhesive application at corners and grooves. The collection box not only recovers excess adhesive but also prevents adhesive dripping onto the base, affecting subsequent clamping accuracy. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a device for applying adhesive to the surface of W-steel strips used in tunnel maintenance. (See also...) Figure 1 The system includes a base 1, with frames 2 mounted on both sides of the base 1. Cylinders 4 are mounted on the frames 2, and the output ends of the cylinders 4 are connected to positioning frames 5. A set of clamping blocks 6 are fixed to the inner wall of the positioning frames 5. Guide rods 3 are symmetrically fixed to both sides of the top of the positioning frames 5, and the guide rods 3 are slidably connected to the frames 2. As the positioning frames 5 move, the clamping blocks 6 are embedded into the slots on the base 1, firmly clamping and fixing the W-shaped steel strip, effectively preventing the W-shaped steel strip from shifting during the adhesive application process and ensuring accurate adhesive application. The guide rods 3 at the top of the positioning frames 5 are slidably connected to the frames 2, providing stable guidance for the movement of the positioning frames 5.

[0021] like Figure 2 As shown, a housing 7 is installed on the side wall of the base 1. Inside the housing 7 is a lead screw assembly, on which a mounting bracket 11 is installed. The mounting bracket 11 houses an adhesive application component. The lead screw assembly includes a motor 8 mounted on one side of the inner wall of the housing 7, a lead screw 9 located inside the housing 7, and a lead screw slider 10 that slides and adapts to the lead screw 9. The output end of the motor 8 drives the lead screw 9. The bottom of the mounting bracket 11 is screwed to the top of the lead screw slider 10. An electric push rod 12 is mounted on the mounting bracket 11. The motor 8 drives the lead screw 9 to rotate, causing the lead screw slider 10 and the mounting bracket 11 to move, thus flexibly adjusting the position of the adhesive application component. This allows for precise control of the adhesive application range according to the adhesive application requirements of the W steel strip. The electric push rod 12 on the mounting bracket 11 can move the adhesive application component up and down, easily adapting to W steel strips of different thicknesses. This eliminates the need to replace the device, meeting diverse adhesive application needs and enhancing the device's versatility.

[0022] like Figure 3 As shown, the adhesive application component includes an adhesive tank 13 fixed to the electric push rod 12, adhesive application heads 15 located on both sides of the bottom of the adhesive tank 13, and adhesive application brushes 16 distributed on the adhesive application heads 15. A material pipe 14 is connected to one side of the top of the adhesive tank 13, and a collection box 17 is fixed to the bottom of the inner wall of the fixing frame 11. In the adhesive application component, the adhesive application brush 16 is made of a relatively soft material, which can fully contact the surface of the W steel strip. Especially for the special "W" shaped structure of the W steel strip, it can fit its corners and grooves, achieving uniform adhesive application during the movement of the fixing frame 11, avoiding missed areas, insufficient application, or accumulation, and improving the adhesive application quality.

[0023] The implementation principle of the W-steel strip surface adhesive coating device for tunnel maintenance according to an embodiment of this application is as follows:

[0024] When applying adhesive to the W-shaped steel strip used for tunnel maintenance, the W-shaped steel strip is first placed on the base 1. Then, the cylinder 4 is started. During operation, its output end drives the positioning frame 5 to move, and the clamping block 6 moves downward and embeds into the slot on the base 1, thus clamping and fixing the W-shaped steel strip placed on the base 1 to prevent the W-shaped steel strip from shifting during the adhesive application process. The guide rods 3 on both sides of the top of the positioning frame 5 are slidably connected to the frame 2, providing guidance for the movement of the positioning frame 5 and ensuring the stability of the clamping action.

[0025] During adhesive application, motor 8 drives lead screw 9 to rotate, causing lead screw slider 10 to move along lead screw 9, which in turn drives the fixed frame 11, which is fixed by the top screw, to move synchronously, thereby adjusting the position of the adhesive application component. The electric push rod 12 on the fixed frame 11 can drive the adhesive application component to move up and down to adapt to the adhesive application requirements of W steel strips of different thicknesses.

[0026] In the adhesive application component, the adhesive tank 13 is connected to an external adhesive pump via the material pipe 14 to receive adhesive. The adhesive application head 15 guides the adhesive to the adhesive application brush 16. The adhesive application brush 16 is made of a soft material and can fully contact the surface of the W steel strip. The adhesive is applied to the surface of the W steel strip during the movement of the fixing frame 11. The collection box 17 at the bottom of the inner wall of the fixing frame 11 can collect the excess adhesive that drips during the adhesive application process, avoiding adhesive waste and contamination of the device.
