Description

Technical Field

[0001] This utility model relates to the technical field of wall surface leveling and screeding, and in particular to a wall surface leveling and screeding device. Background Technology

[0002] In plastering projects, if the wall plastering area is large, one or more mortar lines are usually made on the wall before plastering (generally spaced 1m to 2m apart) to control the plastering thickness and flatness. This process is called mortar screeding.

[0003] Among existing wall leveling and screeding equipment, such as the utility model patent disclosed in application number 202420211255.1, this utility model wall leveling and screeding equipment first adjusts the position and height of the lifting arm when leveling the wall. Then, driven by the cylinder, the guide rail is rotated to a vertical position. After pushing the leveling equipment to the appropriate leveling position, the leveling operation can be performed on the wall. After leveling is completed, the decorator installs the cutting component in the slot and then slides the cutting component from top to bottom to separate the leveled surface from the leveling guide rail, thus completing the leveling process. The leveling steps are simple, and the entire leveling process does not cause any damage to the wall, thus improving the load-bearing life of the wall.

[0004] However, during the wall leveling process, after the equipment is adjusted, the vehicle is moved to level the surface. Due to the unevenness of the travel path, the final leveling effect will be poor. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a wall screed leveling device that reduces the drawbacks of overall movement during the wall screed leveling process by setting up a clamping mechanism and a squeezing mechanism, and uses a slide rail to scrape along the path to improve the leveling quality.

[0006] This utility model provides a wall leveling and screeding device, which includes a moving mechanism; it also includes a tightening mechanism, a pressing mechanism, a lifting mechanism and a screeding mechanism. The tightening mechanism is installed on the moving mechanism, the pressing mechanism is installed on the moving mechanism, the lifting mechanism is installed at the upper end of the moving mechanism, and the screeding mechanism is installed on the lifting mechanism.

[0007] The moving mechanism moves the equipment, the tightening mechanism tightens it, the pressing mechanism presses it, the lifting mechanism raises and lowers it, and the screeding mechanism smooths it. The moving mechanism facilitates equipment movement, the tightening mechanism keeps the equipment pressed against the wall, the pressing mechanism limits the equipment's pressure, the lifting mechanism adjusts the smoothing height, and the screeding mechanism smooths the surface. This reduces the drawbacks of overall movement during the wall screeding and leveling process, and the use of slide rails for smoothing along the path improves the smoothing quality.

[0008] Preferably, the moving mechanism includes a base frame and four sets of casters, with the four sets of casters installed at the lower end of the base frame; the casters facilitate the movement of the base frame.

[0009] Preferably, the clamping mechanism includes a top shovel and a screw rod. The top shovel is slidably mounted on the base frame, and the screw rod is rotatably mounted on the upper end of the base frame. The screw rod is threadedly engaged with the top shovel. By rotating the screw rod to engage with the top shovel, the top shovel is raised and lowered to the bottom end, and the top shovel clamps against the corner of the wall for limiting.

[0010] Preferably, the pressing mechanism includes a limiting frame, two sets of ratchet teeth, two sets of springs, a ratchet shaft, two sets of half gears, a push handle, a second set of ratchet teeth, and two sets of springs. The limiting frame is installed on the upper end of the base frame. Both sets of ratchet teeth are slidably installed on the limiting frame via a set of springs. The ratchet shaft is rotatably installed on the limiting frame. The two sets of half gears are installed on the ratchet shaft. The push handle is rotatably installed on the limiting frame. The second set of ratchet teeth is slidably installed on the push handle via two sets of springs. By pushing the push handle, the second set of ratchet teeth moves the ratchet shaft, thereby causing the ratchet shaft to drive the half gears to rotate and contact the ground, so that the half gears press against the ground for fixation. At the same time, the first set of ratchet teeth locks the ratchet shaft. The first and second sets of ratchet teeth can be released by moving the ratchet shaft.

[0011] Preferably, the lifting mechanism includes a telescopic cylinder and a slide rail. The telescopic cylinder is mounted and locked on the base frame, and the slide rail is mounted and locked on the telescopic cylinder. The slide rail is raised or lowered by opening the telescopic cylinder.

[0012] Preferably, the screeding mechanism includes a slide, a tool holder, a second screw, a handwheel, and a scraper. The slide is slidably mounted on a slide rail, the tool holder is slidably mounted on the slide, the second screw is rotatably mounted on the slide, and the second screw is threadedly engaged with the tool holder. The output end of the handwheel is connected to the input end of the second screw, and the scraper is mounted on the tool holder. Rotating the handwheel drives the second screw to rotate, and as the second screw rotates, it engages with the tool holder, causing the tool holder to move, thereby pushing the slide and causing the scraper to smooth the surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the moving mechanism facilitates the movement of the equipment, the clamping mechanism makes the equipment press against the wall, the squeezing mechanism makes the equipment squeeze and limit, the lifting mechanism adjusts the leveling height, and the screeding mechanism performs leveling, thereby reducing the disadvantages of overall movement during the wall screeding and leveling process, and using a slide rail for leveling along the path improves the leveling quality.

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] Example 1

[0022] like Figures 1 to 5 As shown, a wall leveling and screeding device includes a moving mechanism 1, a tightening mechanism 2, a pressing mechanism 3, a lifting mechanism 4, and a screeding mechanism 5. The tightening mechanism 2 is installed on the moving mechanism 1, the pressing mechanism 3 is installed on the moving mechanism 1, the lifting mechanism 4 is installed on the upper end of the moving mechanism 1, and the screeding mechanism 5 is installed on the lifting mechanism 4.

[0023] The moving mechanism 1 moves, the clamping mechanism 2 clamps, the squeezing mechanism 3 squeezes, the lifting mechanism 4 lifts, and the punching mechanism 5 flattens.

[0024] The moving mechanism 1 includes a base frame 11 and four sets of casters 12, with the four sets of casters 12 installed at the lower end of the base frame 11;

[0025] The clamping mechanism 2 includes a top shovel 21 and a screw 22. The top shovel 21 is slidably mounted on the base frame 11, and the screw 22 is rotatably mounted on the upper end of the base frame 11. The screw 22 is threadedly engaged with the top shovel 21.

[0026] The extrusion mechanism 3 includes a limiting frame 31, two sets of ratchet teeth 32, two sets of springs 33, a ratchet shaft 34, two sets of half gears 35, a push handle 36, a second ratchet tooth 37, and two sets of springs 38. The limiting frame 31 is mounted on the upper end of the base frame 11. Both sets of ratchet teeth 32 are slidably mounted on the limiting frame 31 through a set of springs 33. The ratchet shaft 34 is rotatably mounted on the limiting frame 31. The two sets of half gears 35 are mounted on the ratchet shaft 34. The push handle 36 is rotatably mounted on the limiting frame 31. The second ratchet tooth 37 is slidably mounted on the push handle 36 through two sets of springs 38.

[0027] The lifting mechanism 4 includes a telescopic cylinder 41 and a slide rail 42. The telescopic cylinder 41 is locked on the base frame 11, and the slide rail 42 is locked on the telescopic cylinder 41.

[0028] The punching mechanism 5 includes a slide 51, a tool holder 52, a second screw 53, a handwheel 54, and a scraper 55. The slide 51 is slidably mounted on the slide rail 42, the tool holder 52 is slidably mounted on the slide 51, the second screw 53 is rotatably mounted on the slide 51, and the second screw 53 is threadedly engaged with the tool holder 52. The output end of the handwheel 54 is connected to the input end of the second screw 53, and the scraper 55 is mounted on the tool holder 52.

[0029] The casters 12 facilitate the movement of the base frame 11. The screw 22 is rotated and engaged with the top shovel 21 to raise and lower the top shovel 21 to the bottom. The top shovel 21 is then pressed against the corner of the wall for a limit position. Pushing the handle 36 causes the ratchet 37 to move the ratchet shaft 34, which in turn drives the half gear 35 to rotate and contact the ground, thus fixing the half gear 35 against the ground. At the same time, the ratchet 32 ​​locks the ratchet shaft 34. The ratchet 34 can be released by moving the ratchet 34. Opening the telescopic cylinder 41 allows the slide rail 42 to be raised and lowered to adjust the leveling height. Rotating the handwheel 54 drives the screw 53 to rotate. As the screw 53 rotates, it engages with the blade holder 52, causing the blade holder 52 to move. This pushes the slide 51 to allow the scraper 55 to level the wall surface. This reduces the disadvantages of overall movement during the wall screed leveling process. Using the slide rail for leveling along the path improves the leveling quality.

[0030] like Figures 1 to 5As shown, this utility model discloses a wall leveling and screeding device. During operation, the universal wheels 12 facilitate the movement of the base frame 11. The rotating screw 22 engages with the top shovel 21, causing the top shovel 21 to rise and fall to its bottom position. The top shovel 21 then presses against the corner of the wall for a limiting position. Pushing the handle 36 causes the ratchet 2 37 to move the ratchet shaft 34, which in turn drives the half-gear 35 to rotate and contact the ground, thus fixing the half-gear 35 against the ground. Simultaneously, the ratchet 1 32 locks the ratchet shaft 34. The ratchet 1 32 and ratchet 2 37 can be released by moving the ratchet shaft 34. Opening the telescopic cylinder 41 allows the slide rail 42 to rise and fall, adjusting the leveling height. Rotating the handwheel 54 drives the screw 2 53 to rotate. Simultaneously, the screw 2 53 engages with the blade holder 52, causing the blade holder 52 to move, thereby pushing the slide 51 to allow the scraper 55 to level the surface.

[0031] The telescopic cylinder 41 of this utility model is purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0032] The main function achieved by this utility model is: during the wall surface leveling process, by setting up a tightening mechanism and a squeezing mechanism, the drawbacks of overall movement are reduced during the wall surface leveling process, and the leveling quality is improved by using a sliding rail for leveling along the path.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
