Description

Technical Field

[0001] This invention relates to the field of building measurement technology, and in particular to a positioning and leveling device for building measurement. Background Technology

[0002] In the field of building decoration, walls or floors are usually covered with various types of boards, such as ceramic tiles, cement boards, and wood boards. Before these boards are laid on the floor of a house, workers need to level the floor to ensure that the flatness of the floor meets certain standards.

[0003] However, when leveling the ground, workers usually bend over and use wooden boards to scrape the cement surface. This long-term bending over leveling work greatly increases the workers' workload. At the same time, it is difficult to guarantee the accuracy of manual leveling. Sometimes, unevenness will still occur in some areas. As a result, the installation accuracy and effect of tiles are often affected by the uneven base, which has certain limitations.

[0004] Therefore, it is necessary to provide a positioning and leveling device for house measurement to solve the above-mentioned technical problems. Summary of the Invention

[0005] The technical problem solved by the present invention is to provide a positioning and leveling device for house measurement that is easy to use, automatically levels the entire floor of a house, and reduces the workload of workers.

[0006] To solve the above-mentioned technical problems, the present invention provides a positioning and leveling device for house measurement, comprising: a long plate, on which first electric push rods are fixedly installed on the outer walls of both sides of the long plate, and on which extrusion plates are fixedly installed on the two output shafts of the two first electric push rods, and on which the outer walls of the two extrusion plates are respectively rolled with a plurality of rolling balls, a rotating screw threadedly installed on the long plate and passing through the long plate, a connecting plate rotatably installed at the bottom end of the rotating screw, a vertical plate fixedly installed at the bottom of the connecting plate, a pressure plate fixedly installed at the bottom of the vertical plate, second electric push rods fixedly installed on the outer walls of both sides of the vertical plate, scrapers fixedly installed on the two output shafts of the two second electric push rods, and the bottom of the two scrapers is flush with the bottom of the pressure plate, a protective tube fixedly installed at the top of the long plate, a sealing cover plate provided at the top end of the protective tube, a rotating plate fixedly installed at the top end of the rotating screw, and sliding rods slidably installed on the rotating plate, and the top ends of the two sliding rods are fixedly connected to the sealing cover plate.

[0007] Preferably, two limiting rods are fixedly installed on the top of the connecting plate, and both limiting rods penetrate the long plate and are slidably connected to the long plate.

[0008] Preferably, a short plate is fixedly installed at the bottom end of each of the two sliding rods, a compression spring is movably sleeved on each of the two sliding rods, and the top ends of the two compression springs are fixedly connected to the rotating plate, and the bottom ends of the two compression springs are fixedly connected to the corresponding short plates.

[0009] Preferably, the sealing cover has a circular opening, and a drying barrel is fixedly installed inside the circular opening. The drying barrel contains a desiccant. Two connection openings are opened on the outer wall of the drying barrel, and isolation nets are fixedly installed in the two connection openings respectively. A circular cover is provided inside the drying barrel, and two slots are opened on the circular cover. Two locking rods are slidably installed on the drying barrel, and the ends of the two locking rods that are close to each other extend into the corresponding slots. Movable plates are fixedly installed at the ends of the two locking rods that are far apart from each other.

[0010] Preferably, each of the two clamping rods is movably fitted with a force spring, and one end of each of the two force springs is fixedly connected to the corresponding movable plate, while the other end of each of the two force springs is fixedly connected to the drying barrel.

[0011] Preferably, an annular limiting sealing plate is fixedly installed inside the drying barrel.

[0014] Compared with related technologies, the positioning and leveling device for house measurement provided by the present invention has the following beneficial effects:

[0015] This invention provides a positioning and leveling device for measuring a house. The device uses the extension of the output shafts of two first electric push rods to move a pressing plate and a rolling ball away from each other, bringing them into contact with the side walls of the house. The pressing action of the rolling ball against the side walls forces the device into the house. An external level is used to adjust the long plate, ensuring the device is horizontally installed between the two walls. Moving the sealing cover upwards and rotating it clockwise moves two scrapers and a pressing plate downwards, bringing them into contact with the ground and flattening the cement mortar. The extension of the output shafts of two second electric push rods then moves two scrapers away from each other, further leveling the cement mortar. By pushing the device horizontally along the walls, other areas of the floor are leveled. Repeating this process allows for the leveling of the room. The device automatically levels the entire floor using a second electric push rod, eliminating the need for workers to bend over and significantly reducing workload. It also ensures consistent leveling accuracy, preventing unevenness from affecting tile installation precision and results. Protective tubes and sealing covers prevent external objects from colliding with the rotating screw, thus protecting its lifespan. A desiccant absorbs water vapor entering the protective tube, preventing oxidation and rust on the screw surface. Moving the moving plate moves the clamping rod out of the slot, and lifting the circular cover opens the drying container for desiccant replacement. The process is simple, quick, and highly efficient. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

[0027] Please refer to the following: Figures 1-6In the first embodiment of the present invention, the positioning and leveling device for house measurement includes: a long plate 1, with first electric push rods 3 fixedly installed on the outer walls of both sides of the long plate 1, and extrusion plates 4 fixedly installed on the two output shafts of the two first electric push rods 3, respectively. A plurality of rolling balls 5 are rolled on the outer walls of the two extrusion plates 4 on the side away from each other. The extrusion plates 4 and rolling balls 5 are moved away from each other and contact the two side walls of the house by the extension of the output shafts of the two first electric push rods 3. The device is installed on the house by the extrusion of the rolling balls 5 by the extrusion of the two side walls. The rolling ball 5 is rolled on the extrusion plate 4, thus allowing the device to move horizontally along the wall and be moved to other locations in the room for leveling. A rotating screw 2 is threaded onto the long plate 1, passing through it. A connecting plate 6 is rotatably mounted at the bottom of the rotating screw 2. To limit the movement of the connecting plate 6 and maintain its stability, the extrusion plate 9 and scraper 10 are kept stable while leveling the floor. Two limiting rods 14 are fixedly mounted on the top of the connecting plate 6. Both limiting rods 14 penetrate the long plate 1 and are slidably connected to it. A vertical plate 7 is fixedly installed at the bottom of the connecting plate 6, and a pressure plate 9 is fixedly installed at the bottom of the vertical plate 7. Second electric push rods 8 are fixedly installed on the outer walls of both sides of the vertical plate 7. Scrapers 10 are fixedly installed on the two output shafts of the two second electric push rods 8, and the bottoms of the two scrapers 10 are flush with the bottom of the pressure plate 9. By extending the output shafts of the two second electric push rods 8, the two scrapers 10 are moved away from each other to smooth the cement mortar on the ground. By pushing this device on the wall... The horizontal movement is used to level the ground in other locations. By repeating the above operation, the entire floor of the room can be leveled. A protective tube 12 is fixedly installed on the top of the long plate 1, and a sealing cover plate 13 is provided at the top of the protective tube 12. A rotating plate 11 is fixedly installed on the top of the rotating screw 2. Sliding rods 15 are slidably installed on the rotating plate 11, and the tops of the two sliding rods 15 are fixedly connected to the sealing cover plate 13. The protective tube 12 and the sealing cover plate 13 prevent external objects from colliding with the rotating screw 2, causing damage to the rotating screw 2 and affecting its service life.

[0028] In order to ensure that the sealing cover 13 remains in close contact with the protective tube 12 without being subjected to other external forces, thereby blocking the protective tube 12 and preventing external dust from entering the protective tube 12 and adhering to the rotating screw 2, thus affecting the service life of the rotating screw 2, short plates 26 are fixedly installed at the bottom ends of the two sliding rods 15 respectively. Compression springs 16 are movably sleeved on the two sliding rods 15 respectively, and the top ends of the two compression springs 16 are fixedly connected to the rotating plate 11. The bottom ends of the two compression springs 16 are fixedly connected to the corresponding short plates 26 respectively.

[0029] To absorb water vapor entering the protective tube 12 and prevent it from oxidizing and rusting the surface of the rotating screw 2, thus avoiding slippage and reduced work efficiency, a circular opening is provided on the sealing cover 13. A drying barrel 17 is fixedly installed inside the circular opening, and a desiccant 18 is placed inside the drying barrel 17. Two connection openings are provided on the outer wall of the drying barrel 17, and isolation nets 19 are fixedly installed in each of the two connection openings. The isolation nets 19 ensure that the desiccant 18 remains inside the drying barrel 17 and cannot come into contact with the rotating screw 2, thus preventing contact between the desiccant 18 and the rotating screw 2 and affecting its service life. A circular cover 21 is provided inside the drying barrel 17, and two slots 22 are provided on the circular cover 21 to block the gap between the circular cover 21 and the drying barrel 17. To prevent external dust from entering the drying barrel 17 through the gap and adhering to the rotating screw 2, thus affecting the service life of the rotating screw 2, an annular limiting sealing plate 20 is fixedly installed inside the drying barrel 17. Two locking rods 23 are slidably installed on the drying barrel 17, with the ends of the two locking rods 23 approaching each other and extending into corresponding locking grooves 22, and the ends of the two locking rods 23 away from each other being fixedly installed with movable plates 25. In order to ensure that one end of the locking rod 23 is always located in the locking groove 22 to hold the circular cover plate 21 without being subjected to other external forces, thereby fixing the circular cover plate 21 on the device, force springs 24 are movably sleeved on the two locking rods 23, and one end of the two force springs 24 is fixedly connected to the corresponding movable plates 25, and the other end of the two force springs 24 is fixedly connected to the drying barrel 17.

[0030] To ensure that the desiccant 18 inside the drying container 17 is always in a stirred and flowing state, and thus that the desiccant 18 absorbs water vapor evenly in the protective tube 12, preventing the upper desiccant 18 from becoming saturated while the lower desiccant 18 remains saturated, which would require time to separate and reuse when replacing the desiccant 18, thus affecting work efficiency, two mounting rods 27 are fixedly installed inside the drying container 17. A fixing tube 29 is fixedly installed at one end of the rods 27 that are close to each other. A rotating rod is rotatably installed inside the drying barrel 17. In order to rotate the rotating rod inside the drying barrel 17, a rotating hole is opened on the drying barrel 17. A rotating bearing is fixedly installed in the rotating hole. The rotating rod passes through the rotating bearing and is fixedly connected to the inner wall of the rotating bearing. The bottom end of the rotating rod extends to the bottom of the drying barrel 17. An auger 28 is fixedly installed at the top end of the rotating rod. A rotating motor 30 is fixedly installed at the bottom of the drying barrel 17, and the output shaft of the rotating motor 30 is fixedly connected to the bottom end of the rotating rod.

[0031] The working principle of the positioning and leveling device for house measurement provided by this invention is as follows: In the initial state, the compression spring 16 is in a stretched state, the force spring 24 is in a free state, and one end of the clamping rod 23 is located in the clamping groove 22. When this device is needed to level the ground, first pour cement mortar on the ground, place this device in the house, so that the pressing plate 9 and scraper 10 are above the ground, start the two first electric push rods 3, the output shafts of the two first electric push rods 3 extend, driving the pressing plate 4 and the rolling ball 5 to move away from each other and contact the two side walls of the house, and press against the two walls. The pressing of the rolling ball 5 by the two side walls installs this device in the house. The levelness of the long plate 1 is adjusted by an external level, so that... This device is horizontally installed between two walls. Moving the sealing cover 13 upwards separates it from the protective pipe 12. Rotating the sealing cover 13 clockwise causes the sliding rod 15 to rotate, which in turn rotates the rotating plate 11. The rotating plate 11 then rotates the rotating screw 2, causing it to move downwards. The downward movement of the rotating screw 2 causes the connecting plate 6 to move downwards, which in turn causes the vertical plate 7 to move downwards. The downward movement of the vertical plate 7 causes the two scrapers 10 and the pressing plate 9 to move downwards and contact the ground, thus flattening the cement mortar on the ground. Simultaneously, two second electric push rods 8 are activated. The output shafts of the two second electric push rods 8 extend, causing the two scrapers 10 to move away from each other, scraping the cement mortar on the ground. After the floor leveling work in this area is completed, the rolling ball 5, which is rolled on the extrusion plate 4, can push the device horizontally along the wall, thereby moving the device to other locations in the room to level other areas. By repeating this operation, the entire floor in the room can be leveled. Since the device automatically levels the floor by extending the second electric push rod 8, workers do not need to bend over, greatly reducing labor intensity. It also ensures consistent floor leveling accuracy, preventing uneven areas and ensuring that unevenness does not affect the accuracy and effect of tile installation. This is achieved through the protective pipe 12 and... The sealing cover 13 protects the rotating screw 2 from external objects colliding with it, preventing damage and extending its service life. The desiccant 18 absorbs water vapor entering the protective tube 12, preventing oxidation and rust on the surface of the rotating screw 2, which could cause slippage when rotating the screw 2 and affect work efficiency. When the desiccant 18 needs to be replaced, the moving plate 25 moves the locking rod 23 out of the locking slot 22. When the locking rod 23 is completely out of the locking slot 22, the circular cover 21 changes from a locked state to a free state. Moving the circular cover 21 upwards opens the drying container 17, allowing the operator to replace the desiccant 18. The process is simple and highly efficient.

[0032] Compared with related technologies, the positioning and leveling device for house measurement provided by the present invention has the following beneficial effects:

[0033] This invention provides a positioning and leveling device for measuring a house. The output shafts of two first electric push rods 3 extend, causing a pressing plate 4 and a rolling ball 5 to move away from each other and contact the two side walls of the house. The pressing of the rolling ball 5 by the side walls forces the device into the house. An external level is used to adjust a long plate 1, ensuring the device is horizontally installed between the two walls. Moving the sealing cover 13 upwards and rotating it clockwise causes two scrapers 10 and a pressing plate 9 to move downwards and contact the ground, thus flattening the cement mortar. The output shafts of two second electric push rods 8 extend, causing the two scrapers 10 to move away from each other and scrape the cement mortar. By pushing the device horizontally along the walls, other areas of the floor are leveled. Repeating this process allows for the leveling of the entire room. The ground is leveled automatically by extending the second electric push rod 8, eliminating the need for workers to bend over. This significantly reduces workload and ensures consistent leveling accuracy, preventing unevenness from affecting tile installation precision and results. The protective tube 12 and sealing cover 13 prevent external objects from colliding with the rotating screw 2, thus protecting its lifespan. The desiccant 18 absorbs water vapor entering the protective tube 12, preventing oxidation and rust on the screw 2. Moving the moving plate 25 moves the clamping rod 23 out of the slot 22, and moving the circular cover 21 upwards opens the drying container 17 for desiccant replacement. The process is simple, quick, and highly efficient.

[0034] Second embodiment:

[0035] Based on the house measurement positioning and leveling device provided in the first embodiment of this application, the second embodiment of this application proposes another house measurement positioning and leveling device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0036] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] Please refer to the following: Figure 7-8The positioning and leveling device for house measurement also includes two mounting rods 27, which are installed inside the drying barrel 17. A fixing pipe 29 is fixedly installed at one end of the two mounting rods 27 that are close to each other. A rotating rod is rotatably installed inside the drying barrel 17, and the bottom end of the rotating rod extends to the bottom of the drying barrel 17. An auger 28 is fixedly installed at the top end of the rotating rod. A rotating motor 30 is fixedly installed at the bottom of the drying barrel 17, and the output shaft of the rotating motor 30 is fixedly connected to the bottom end of the rotating rod.

[0038] A rotating hole is provided on the drying barrel 17, and a rotating bearing is fixedly installed in the rotating hole. The rotating rod passes through the rotating bearing and is fixedly connected to the inner wall of the rotating bearing.

[0039] The rotating motor 30 drives the auger 28 to rotate, which in turn transports the desiccant 18 at the bottom of the drying barrel 17 to the fixed pipe 29. Finally, the desiccant 18 is transported to the top of the barrel through the fixed pipe 29. This keeps the desiccant 18 in the drying barrel 17 in a constantly stirred and flowing state, so that the desiccant 18 can evenly absorb the water vapor in the protective pipe 12. This prevents the desiccant 18 at the top from becoming saturated with water vapor while the desiccant 18 at the bottom has not yet absorbed any water vapor. Otherwise, when replacing the desiccant 18, people would have to spend time separating the desiccant 18 at the bottom for reuse, which would affect work efficiency.

[0040] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
