[0002] In building construction, the wire rack is mainly used to assist construction personnel in determining key positions such as the axis and edge lines of the building, providing an accurate benchmark for subsequent foundation construction, wall masonry, formwork installation and other work, ensuring the size accuracy and position accuracy of the building.

[0003] A wire pay-off frame for building construction is disclosed in Chinese patent publication number CN220617907U. The wire pay-off frame for building construction cooperates with a moving frame in motion through a cleaning transmission component to drive a rotating roller and a cleaning brush to rotate, thereby cleaning the rope.

[0004] However, compared with the existing technology in the related field, it is impossible to clean the wire body from multiple angles by rotating multiple cleaning brushes, and impurities will accumulate on the wire body, which greatly reduces the cleaning effect. In addition, impurities that are tightly attached may not be effectively removed, which may cause the wire body to become stuck, worn, and change in diameter due to stains and other problems during use, which in turn causes deviations in the wire pay-off position. The wire body and the take-up roller may also be damaged due to excessive local accumulation. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background technology, and provide a wire-laying frame for building construction.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] Additional aspects and advantages of the present invention will be further described below in conjunction with the accompanying drawings, and some will become apparent from the following description or be learned through practice of the present invention.

[0029] like Figures 1 to 9 As shown, a wire pay-off frame for building construction comprises a mounting frame 1, a winding mechanism 2 and a driving mechanism 3 are fixedly mounted on the top of the mounting frame 1, a wire assembly 4 is provided on the driving mechanism 3 for reciprocating sliding, so that the wire passing through the inside of the wire assembly 4 can be evenly wound on the winding mechanism 2, and the side where the winding mechanism 2 is installed is defined as the rear side; the wire assembly 4 comprises a fixed seat 401, and two guide rollers 402 are symmetrically rotated on the rear side of the fixed seat 401, and a rotating drum 5 is rotated inside the fixed seat 401, A plurality of brush rollers 6 are provided for the internal relative movement or circumferential rotation of the rotating drum 5, and the plurality of brush rollers 6 are connected to the rotating drum 5 through a matching component 7. A linkage component 8 is provided on the front side of the driving mechanism 3, and a guide component 9 is provided on the front side of the fixed seat 401. When the fixed seat 401 slides back and forth on the driving mechanism 3, the linkage component 8 is used to cause the rotating drum 5 to drive the plurality of brush rollers 6 to rotate circumferentially. When the rotating drum 5 drives the plurality of brush rollers 6 to rotate circumferentially, the guide component 9 is used to control the plurality of brush rollers 6 to rotate on themselves and move relative to each other.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the driving mechanism 3 includes a slide rail 301 fixedly mounted on the mounting frame 1, and a double-wire reciprocating screw 302 is provided for rotation inside the slide rail 301, a driving element 303 is fixedly mounted on one end of the slide rail 301, and a moving block 4011 is fixedly provided at the bottom of the fixed seat 401 for sliding cooperation with the slide rail 301, and a screw hole matching with the position of the moving block 4011 corresponding to the double-wire reciprocating screw 302 is opened, and the driving element 303 is used to control the double-wire reciprocating screw 302 to rotate in one direction, and the cooperation between the screw hole and the double-wire reciprocating screw 302 can be utilized to make the moving block 4011 drive the fixed seat 401 to slide back and forth left and right on the slide rail 301.

[0031] like Figure 8 and Fig. 9As shown, the rear end of the rotating drum 5 is open, and a threading hole 501 is provided at the front end of the rotating drum 5. A plurality of balls 502 are provided inside the threading hole 501. By utilizing the provided balls 502, after the line body passes through the threading hole 501, the outer surfaces of the plurality of balls 502 can be attached to the outer surface of the line body, thereby improving the stability of the line body when releasing or reeling in the line, and reducing the wear of the line body. The rotating drum 5 is formed with a conical surface, and the end with a smaller diameter of the conical surface faces the threading hole 501. By utilizing the provided conical surface, dirt that falls off the surface of the line body can be automatically discharged from the inside of the rotating drum 5. A rotating hole is provided at the position of the fixed seat 401 corresponding to the rotating drum 5. The rotating drum 5 is connected to the rotating hole through a bearing, so that by utilizing the provided bearing, the friction force when the rotating drum 5 rotates can be reduced, and the stability of the rotating drum 5 when rotating can be improved.

[0032] like Figure 8 and Fig. 9 As shown, the mating component 7 includes a slider 701 rotatably arranged on the outer surface of the front end of the brush roller 6, and the positions of the rotating drum 5 corresponding to the plurality of sliders 701 are provided with slide grooves 503, and the sliders 701 and the slide grooves 503 are matingly connected via elastic members 702, and the positions of the sliders 701 corresponding to the brush roller 6 are provided with rotation holes, and the brush roller 6 is matingly connected to the rotation holes via bearings, so that the above-mentioned bearings can be used to reduce the friction force of the brush roller 6 during rotation, and improve the stability of the brush roller 6 during rotation.

[0033] like Figure 3 , Figure 4 and Figure 7 As shown, the linkage assembly 8 includes a rack 801 fixedly mounted on the driving mechanism 3, and a first gear ring 802 meshing with the rack 801 is fixedly provided on the outer surface of the rotating drum 5. When the moving block 4011 drives the fixed seat 401 to slide back and forth left and right on the slide rail 301, the cooperation between the first gear ring 802 and the rack 801 is utilized to enable the rotating drum 5 to drive the multiple brush rollers 6 to rotate circumferentially.

[0034] like Figure 5 , Figure 6 and Figure 8As shown, the guide assembly 9 includes a fixing frame 901 fixedly mounted on the front side of the fixing seat 401, and a special-shaped gear ring 902 is fixedly mounted on the fixing frame 901. The special-shaped gear ring 902 is concentric with the rotating drum 5, and one end of the plurality of brush rollers 6 close to the special-shaped gear ring 902 is fixedly provided with a gear 903 meshing with it. The inner wall of the special-shaped gear ring 902 is alternately provided with a plurality of arc-shaped meshing grooves and a plurality of arc-shaped meshing convex grooves and forms a circle around a circle. When the rotating drum 5 drives the plurality of brush rollers 6 to rotate circumferentially, By utilizing the cooperation between the gear 903 and the special-shaped gear ring 902, the multiple brush rollers 6 can be allowed to rotate on their own and move closer to or away from each other (when the gear 903 engages with the arc-shaped meshing convex groove, the multiple brush rollers 6 will approach each other, and the slider 701 will pull the elastic member 702. When the gear 903 engages with the arc-shaped meshing groove, the elastic force of the elastic member 702 is used to pull the slider 701 and the brush roller 6 back, thereby moving the multiple brush rollers 6 away from each other).

[0035] In summary, the effects of the rotating drum 5 driving the multiple brush rollers 6 to rotate in the circumferential direction and the multiple brush rollers 6 to rotate and move relative to each other are as follows:

[0036] Circumferential rotation cleaning of the brush roller 6: When the fixed seat 401 slides back and forth, the rotating drum 5 will drive the multiple brush rollers 6 to rotate circumferentially. During the process of paying out and taking up the line, the line passes between the multiple axially arranged brush rollers 6. The circumferentially rotating brush roller 6 can comprehensively clean the surface of the line (for example, in a construction environment, the surface of the line may be contaminated with dust, mud and other impurities), thereby brushing these impurities off the surface of the line and keeping the line clean.

[0037] Self-rotation cleaning of the brush roller 6: Utilizing the self-rotation of multiple brush rollers 6, the self-rotating brush rollers 6 can clean the wire body from different angles, further enhancing the cleaning effect (for example, there may be some stubborn stains or particles on the surface of the wire body, and the self-rotation of the brush roller 6 can more effectively remove these stains and particles. Compared with the cleaning method in a single direction, the combination of self-rotation and circumferential rotation can clean the wire body more thoroughly).

[0038] Relative motion cleaning of the brush roller 6: while the rotating drum 5 drives the multiple brush rollers 6 to rotate circumferentially, the multiple brush rollers 6 will move closer to and away from each other, thereby rubbing the surface of the wire. This rubbing action is similar to manual rubbing, and can more thoroughly remove stains, impurities, etc. on the surface of the wire. Especially for some tightly attached impurities, the rubbing cleaning method can better play a role, further improve the cleaning effect of the wire surface, and ensure the accuracy and reliability of the wire during the construction process.

[0039] The winding mechanism 2 and the driving mechanism 3 described in the present application are well-known technologies in the technical field, so their specific structures and working principles are not described in detail.

[0040] The working process is as follows:

[0041] S1: Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, when releasing or retrieving the line, the driving element 303 is used to control the double-line reciprocating screw rod 302 to rotate in one direction, and the cooperation between the screw rod hole and the double-line reciprocating screw rod 302 is used to make the moving block 4011 drive the fixed seat 401 to slide back and forth on the slide rail 301;

[0042] S2: Figure 4 and Figure 5 As shown, when the moving block 4011 drives the fixed seat 401 to slide back and forth on the slide rail 301, the first gear ring 802 and the rack 801 cooperate to make the rotating drum 5 drive the multiple brush rollers 6 to rotate circumferentially. During the process of paying out and taking up the line, the line passes between the multiple axially arranged brush rollers 6. The circumferentially rotating brush rollers 6 can fully clean the surface of the line.

[0043] S3: Figures 5 to 9 As shown, when the drum 5 drives the multiple brush rollers 6 to rotate circumferentially, the cooperation between the gear 903 and the special-shaped gear ring 902 can be used to allow the multiple brush rollers 6 to rotate on their own and to move closer to or farther from each other (when the gear 903 is engaged with the arc-shaped meshing convex groove, the multiple brush rollers 6 will move closer to each other, and the slider 701 will pull the elastic member 702 at this time. When the gear 903 is engaged with the arc-shaped meshing groove, the slider 701 and the brush roller 6 are pulled back by the elastic force of the elastic member 702, so that the multiple brush rollers 6 move away from each other). On the one hand, by using the self-rotation of the multiple brush rollers 6, the self-rotating brush rollers 6 can clean the wire body from different angles, further enhancing the cleaning effect. On the other hand, the relative motion of the brush rollers 6 can clean the surface of the wire by rubbing. This rubbing action is similar to manual rubbing, which can more thoroughly remove stains, impurities, etc. on the surface of the wire body. In particular, for some impurities that are relatively tightly attached, the rubbing cleaning method can play a better role.

[0044] S4: Fig. 9 As shown, by utilizing the provided conical surface, dirt falling off the surface of the wire body can be automatically discharged from the inside of the rotating drum 5.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
