Description

Technical Field

[0001] This utility model belongs to the field of ancient building front restoration technology, specifically a wall-walking device for ancient building wall restoration. Background Technology

[0002] Ancient buildings are precious historical and cultural heritages of my country. Their walls (such as palace walls, courtyard walls, and gable walls) often suffer from surface peeling, cracks, and efflorescence after weathering the elements, requiring regular repair and maintenance. Currently, for the restoration of ancient building walls, especially when working on the upper part of taller walls, scaffolding is commonly used to provide a working platform for construction workers.

[0003] However, in actual construction, the surrounding space of many ancient building walls (such as walls on both sides of narrow alleyways, partition walls in courtyards, etc.) is extremely limited, or the ground conditions are complex (such as the presence of greenery, stone paving, etc., which cannot be damaged or occupied). In these cases, it is often only possible to erect very simple support frames close to the wall surface, which cannot form a platform wide enough for workers to stand and work safely.

[0004] Faced with these difficulties, construction workers are currently often forced to adopt a high-risk traditional method: working directly on top of the wall to be repaired. To ensure safety, workers need to wear safety harnesses (safety belts) and secure safety ropes to a stable structure (such as a roof truss, a large tree, or a specially installed counterweight) on the other side of the top of the wall.

[0005] While this method of operation barely solves the problem of work location, the width of the wall top is usually limited. When workers move, squat, or perform operations on it, they are very likely to lose their balance and fall from the top of the wall. Although safety ropes serve as a last line of defense to prevent people from falling directly to the ground, the fall process itself is extremely dangerous and can easily lead to injury. Utility Model Content

[0006] This utility model provides a wall-walking device for the repair of ancient building walls, in order to solve the defects in the existing technology.

[0007] This utility model is achieved through the following technical solution: A wall-walking device for the repair of ancient building walls includes a base plate. The base plate has clamps vertically downward on both sides of its bottom surface. The clamps move laterally in opposite directions and remain stationary via a driving device. A U-shaped plate with an upward opening is provided above the base plate. The U-shaped plate is rotatably connected to the base plate. Elastic shoe uppers are fixedly connected between the side plates of the U-shaped plate and the top surface of the middle plate of the U-shaped plate. The worker's foot is placed between the U-shaped plate and the elastic shoe upper.

[0008] In use, the worker places their foot between the U-shaped plate and the elastic shoe upper, allowing the U-shaped plate to move simultaneously with the worker's foot inside. The clamping plate adjusts its spacing according to the drive mechanism and engages with the wall, ensuring the worker can move along the wall (the worker only lifts their foot slightly for lateral movement), thus preventing the risk of falling and effectively protecting the worker. The rotatable connection between the U-shaped plate and the base plate allows the worker to turn around in front.

[0009] Preferably, the two sides of the U-shaped panel are hinged with calf limiting plates via pins. One end of a Velcro strap is fixedly connected to one calf limiting plate, while the other end of the frosted strap is adhered to the other calf limiting plate. The calf limiting plates effectively prevent workers from leaning outwards when squatting, thus protecting not only their ankles but also preventing them from falling off the wall. The hinge between the calf limiting plates and the U-shaped panel ensures the worker can squat comfortably.

[0010] Preferably, the driving device includes a rotating lead screw, and the base plate has a dovetail-shaped groove laterally formed. A slider is slidably fitted within the groove, and the slider has a threaded hole through which the rotating lead screw passes. The rotating lead screw is threaded into the threaded hole, and the rotating lead screw and the groove are rotatably connected via bearings. The clamping plate is fixedly connected to the slider. Rotating the lead screw causes the slider to move, which in turn moves the clamping plate. The dovetail-shaped groove ensures that the slider will not fall out of the groove during sliding.

[0011] Preferably, the base plate has a rotating groove, and the inner wall of the top surface of the rotating groove has a circular through-hole extending upwards. A rotating plate is installed inside the rotating groove, and a rotating shaft extending out of the circular through-hole is vertically and fixedly connected to the top surface of the rotating plate. The rotating shaft is perpendicular to and fixedly connected to the center of the bottom surface of the U-shaped plate. The rotation of the U-shaped plate can drive the rotation of the rotating shaft, thereby causing the rotating plate to rotate within the rotating groove, while preventing the base plate from rotating along with it.

[0012] Preferably, the base plate has ball bearing cavities, which are evenly distributed along the circumference of the circular through-groove. Ball bearings are disposed within these cavities, and the bottom surface of the U-shaped plate contacts and engages with the ball bearings. The ball bearings support the U-shaped plate while ensuring its normal rotation.

[0013] Preferably, the opposing surfaces of the clamping plate are provided with strip grooves, and rolling rollers are installed within the strip grooves. The rolling rollers are rotatably connected to the strip grooves via pins. The rolling rollers can replace the sliding friction between the clamping plate and the wall surface with rolling friction, avoiding damage to the front surface caused by sliding friction between the clamping plate and the front surface.

[0014] The beneficial effects of this utility model are as follows: The use of this application can utilize the cooperation between the U-shaped plate and the clamp to ensure that when workers are on the wall, the clamp limits their movement and prevents them from falling off the wall, effectively protecting the workers who are working on the project.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] A type of wall-walking device for the restoration of ancient building walls, such as Figure 1 As shown. It includes a base plate 1, with clamping plates 4 vertically downwards on both sides of the bottom surface of the base plate 1. The clamping plates 4 move laterally in opposite directions via a driving device and remain stationary. A U-shaped plate 2 with an upward-facing opening is located above the base plate 1. The rotatable connection between the U-shaped plate 2 and the base plate 1 is as follows: a rotating groove is formed on the base plate 1, with a circular through-hole extending upwards from the inner wall of the top surface of the rotating groove. A rotating plate 9 is located within the rotating groove, and a rotating shaft 8 extending through the circular through-hole is vertically and fixedly connected to the top surface of the rotating plate 9. The rotating shaft 8 is perpendicular to and fixedly connected to the center of the bottom surface of the U-shaped plate 2. The rotation of the U-shaped plate 2 drives the rotation of the rotating shaft 8, thereby causing the rotating plate 9 to rotate within the rotating groove, while preventing the base plate 1 from rotating along with it. Elastic shoe uppers 3 are fixedly connected between the side plates of the U-shaped plate 2 and the top surface of the middle plate of the U-shaped plate 2, with the worker's foot placed between the U-shaped plate 2 and the elastic shoe upper 3.

[0020] In use, workers wear safety harnesses to ensure upper body safety, then place their feet between the U-shaped plate 2 and the elastic shoe upper 3. This allows the U-shaped plate 2 to move simultaneously with the worker's feet inside. The clamping plate 4 adjusts its spacing according to the drive mechanism and engages with the wall, ensuring the worker can move along the wall (the worker only lifts their feet slightly for lateral movement), thus preventing falls and effectively protecting workers on construction sites. The rotatable connection between the U-shaped plate 2 and the base plate 1 allows the worker to turn around in front.

[0021] Both sides of the U-shaped panel 2 are hinged with lower leg restraint plates 5 via pins. One end of a Velcro strap is fixedly connected to one lower leg restraint plate 5, while the other end of the frosted strap is adhered to the other lower leg restraint plate 5. The lower leg restraint plates 5 effectively prevent workers from leaning outwards when squatting, thus protecting not only their ankles but also preventing them from falling off the wall. The hinge between the lower leg restraint plates 5 and the U-shaped panel 2 ensures that the worker can squat comfortably.

[0022] The driving device includes a rotating lead screw 6. The base plate 1 has a dovetail-shaped groove 7 laterally formed. A slider slidably fits within the groove 7. The slider has a threaded hole through which the rotating lead screw 6 passes. The rotating lead screw 6 is threaded into the threaded hole, and the rotating lead screw 6 and the groove 7 are rotatably connected via bearings. The clamping plate 4 is fixedly connected to the slider. Rotating the lead screw 6 causes the slider to move, which in turn moves the clamping plate 4. The dovetail-shaped groove 7 ensures that the slider will not detach from the groove while sliding.

[0023] The base plate 1 has a ball bearing cavity 10, which is evenly distributed along the circumference of the circular through groove. Ball bearings 10 are disposed in the ball bearing cavity 10, and the bottom surface of the U-shaped plate 2 contacts and engages with the ball bearings 10. The ball bearings 10 can support the U-shaped plate 2 while ensuring the normal rotation of the U-shaped plate 2.

[0024] The opposing surfaces of the clamping plate 4 are provided with strip-shaped grooves, and a rolling roller 11 is installed in the strip-shaped grooves. The rolling roller 11 is rotatably connected to the strip-shaped grooves via a pin. The rolling roller 11 can replace the sliding friction between the clamping plate 4 and the wall surface with rolling friction, thus avoiding damage to the front surface caused by sliding friction between the clamping plate 4 and the front surface.

[0025] The use of this application can utilize the cooperation between the U-shaped plate 2 and the clamping plate 4 to ensure that when workers are on the wall, the clamping plate 4 can limit their movement and prevent them from falling off the wall, effectively protecting the workers who are working on the project.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
