Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a high-precision leveling device for large-area concrete pouring. Background Technology

[0002] Concrete is commonly used in large-scale construction projects. After the concrete is poured, an important step is to level it, which requires a high-precision leveling device. This device is usually used in conjunction with a laser instrument. When using the leveling device, two movable seats that can control the movement of the frame are first installed on both sides of the concrete. The scraper plate is fixed to the frame with multiple sets of bolts. Then, the two movable seats move the scraper plate through the frame to level the concrete.

[0003] Over time, concrete will wear down the leveling device's scraper blades, and a large amount of concrete will accumulate on them. Since the scraper blades are fixed by multiple sets of bolts, it is inconvenient for workers to disassemble and replace them, thus reducing the efficiency of replacement and maintenance. To address this, we propose a high-precision leveling device for large-area concrete pouring. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figures 1-5In this embodiment of the present invention, a high-precision leveling device for large-area concrete pouring includes: a U-shaped frame 1, with vertical grooves on both sides of the inner wall of the U-shaped frame 1, a cylinder 2 connected to the top of the U-shaped frame 1, and the output end of the cylinder 2 extending to the top of the inner wall of the U-shaped frame 1, a locking mechanism 3 connected to the output end of the cylinder 2, and the locking mechanism 3 extending into the interior of the two vertical grooves, a sleeve assembly 4 provided on the locking mechanism 3, a rotating mechanism 5 provided on the locking mechanism 3, and the rotating mechanism 5 engaging with the locking mechanism 3, a scraper 6 movably inserted into the sleeve assembly 4, two moving assemblies 7 connected to the bottom of the U-shaped frame 1 respectively, a spraying mechanism 8 provided at the top of the cylinder 2, and the spraying mechanism 8 extending to the back of the U-shaped frame 1 and connected to the back of the U-shaped frame 1.

[0025] Specifically, by rotating the rotating mechanism 5 in the reverse direction, the locking mechanism 3 is released from locking the scraper 6. At this time, the scraper 6 can be taken out from the inside of the sleeve assembly 4, completing the disassembly of the scraper 6. The scraper 6 is reinserted into the sleeve assembly 4, and rotating the sleeve assembly 4 in the forward direction will drive the locking mechanism 3 to reinsert the scraper 6 and lock it, thus completing the installation of the scraper 6. The two moving components 7 drive the U-shaped frame 1 to move, and start the spraying mechanism 8 so that the spraying mechanism 8 can spray water on the surface of the smoothed and dried concrete while moving, thereby completing the curing of the concrete by watering.

[0026] Example 2:

[0027] Please see Figures 3-4In this embodiment of the present invention, a high-precision leveling device for large-area concrete pouring includes a locking mechanism 3 comprising a hollow shell 301, a bidirectional threaded rod 302, two threaded blocks 303, two L-shaped plates 304, four hexagonal locking rods 305, and a second gear 306. The hollow shell 301 is connected to the output end of the cylinder 2, and both sides of the hollow shell 301 extend into the interior of two vertical grooves. The bidirectional threaded rod 302 is rotatably connected between the two sides of the inner wall of the hollow shell 301, and one end of the bidirectional threaded rod 302 extends to one side of the hollow shell 301. The two threaded blocks 303 are threadedly connected to the outer surface of the bidirectional threaded rod 302. The two L-shaped plates 304 are respectively connected to the bottom of the two threaded blocks 303, and the two L-shaped plates 304 are respectively located inside the two vertical grooves. The four hexagonal locking rods 305 are respectively connected to the... On one side of two adjacent L-shaped plates 304, the second gear 306 is connected to one end of the bidirectional threaded rod 302. The sleeve assembly 4 includes a frame 401 and a placement groove 402. The frame 401 is connected to the bottom of the hollow shell 301, and two insertion holes are opened on both sides of the frame 401 and the scraper 6. Four hexagonal locking rods 305 are respectively movably inserted into the eight insertion holes. The placement groove 402 is opened at the bottom of the frame 401. The rotating mechanism 5 includes a mounting plate 501, a crossbar 502, a throttle 503 and a first gear 504. The mounting plate 501 is connected to one side of the bottom of the hollow shell 301. The crossbar 502 is rotatably connected to one side of the mounting plate 501. The throttle 503 is connected to one end of the crossbar 502. The first gear 504 is connected to the outer surface of the crossbar 502, and the first gear 504 meshes with the second gear 306.

[0028] Specifically, rotating the handle 503 in the reverse direction drives the first gear 504 to rotate via the crossbar 502. The first gear 504 drives the second gear 306 to rotate the bidirectional threaded rod 302, causing the two threaded blocks 303 to move threadedly and drive the two L-shaped plates 304 to move in opposite directions. This allows the four hexagonal locking rods 305 to be withdrawn from the four insertion holes, releasing the lock on the scraper 6. The scraper 6 is then removed from the placement slot 402, completing the disassembly of the scraper 6. The scraper 6 is then reinserted into the placement slot 402. Rotating the handle 503 in the forward direction causes the four hexagonal locking rods 305 to re-insert into the four insertion holes, locking the scraper 6 and completing the installation of the scraper 6. This allows for convenient replacement of the scraper 6.

[0029] Example 3:

[0030] Please see Figures 1-5In this embodiment of the utility model, a high-precision leveling device for large-area concrete pouring includes a spraying mechanism 8 comprising a water tank 801, a water inlet 802, and a water pump 803. The water tank 801 is connected to the top of the U-shaped frame 1, the water inlet 802 is located at the top of the water tank 801, and the water pump 803 is connected to the back of the water tank 801, with the input end of the water pump 803 extending into the interior of the water tank 801. The spraying mechanism 8 also includes two embedded shells 804, a connecting pipe 805, a connecting pipe 806, and multiple nozzles 807. Both embedded shells 804 are connected to the back of the U-shaped frame 1, the connecting pipe 805 is embedded between the two embedded shells 804, the connecting pipe 806 is connected to the output end of the water pump 803, and one end of the connecting pipe 806 is connected to the outer surface of the connecting pipe 805. Multiple nozzles 807 are equidistantly connected to the outer surface of the connecting pipe 805, and a base 9 is connected to the bottom of both moving components 7.

[0031] Specifically, the water pump 803 is started to transport the water in the water tank 801 to the inside of the connecting pipe 805 through the connecting pipe 806, and finally spray it onto the surface of the concrete through multiple nozzles 807. The U-shaped frame 1 is moved by two moving components 7, so that the multiple nozzles 807 can move while spraying, thereby completing the comprehensive water curing of the concrete. The two bases 9 can improve the stability of the U-shaped frame 1 when it is placed.

[0032] The working principle of this utility model is as follows: the output end of the cylinder 2 extends to drive the hollow shell 301 to descend. The hollow shell 301, through the frame shell 401, drives the scraper 6 to descend to the concrete area to be leveled. Then, the two moving components 7 drive the U-shaped frame 1 to move laterally, which in turn drives the scraper 6 to move and level the concrete. When the scraper 6 needs to be replaced, the operator rotates the handle 503 in the opposite direction. The handle 503 drives the first gear 504 to rotate through the crossbar 502. When the first gear 504 rotates, it will drive the second gear 306 to rotate, causing the bidirectional threaded rod 302 to rotate, so that the two threaded blocks 303 move threadedly, thereby driving the two L-shaped plates 304 to move in opposite directions. This will also cause the four hexagonal locking rods 305 to retract from the four holes opened on the scraper 6, thereby releasing the lock on the scraper 6. At this time, the scraper 6 can be taken out from the inside of the placement groove 402. After disassembling the scraper 6, it is placed back into the placement slot 402. The handle 503 is turned clockwise, allowing the four hexagonal locking rods 305 to re-insert into the four holes, locking the scraper 6 and thus completing the installation and replacement of the scraper 6. After the concrete has been scraped and dried for a period of time, when it needs to be cured, the workers add water to the water tank 801 through the water inlet 802, and then start the water pump 803. The input end of the water pump 803 draws water from the water tank 801 and delivers it to the connecting pipe 806 through the output end of the water pump 803. The water then flows back into the connecting pipe 805 and is finally sprayed out through multiple nozzles 807. The sprayed water falls on the surface of the concrete, and then the U-shaped frame 1 is moved by the two moving components 7, so that the multiple nozzles 807 can move while spraying, thus completing the comprehensive water curing of the concrete.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
