Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of concrete processing, specifically to a concrete leveling device for concrete pouring. Background Technology
[0002] In the construction industry, the surface smoothness of poured concrete has a crucial impact on project quality. With the rapid development of the construction industry, traditional manual concrete leveling methods are inefficient and lack precision, making it difficult to meet the requirements of large-scale, high-quality construction. Existing concrete leveling devices also have shortcomings in structural design and functional implementation, such as inconvenient operation, uneven leveling results, and inability to adapt to complex construction environments. Therefore, developing a highly efficient, precise, and adaptable concrete leveling device for concrete pouring has become an urgent problem to be solved in the construction industry.
[0003] Application number CN202421411042.X discloses a concrete leveling device for concrete pouring, including a mounting frame, a connecting frame, a mounting component, a baffle, a transmission component, moving wheels, a movable scraper plate, a fixed frame, a vibrating plate, and a battery. The connecting frame is fixedly connected to one end of the mounting frame, the mounting component is installed at the bottom of the connecting frame, the baffle is fixedly connected to one side of the mounting component, the transmission component is installed at the top of the mounting component, and the moving wheels are fixedly connected to the other end of the transmission component. This concrete leveling device for concrete pouring uses the mounting component to drive the transmission component, causing the scraper plate to level the poured concrete. The back-and-forth scraping operation ensures high flatness of the concrete. The baffle ensures that the scraped concrete does not deviate from the leveling range. The leveled concrete is then further leveled by the vibrating plate, improving leveling efficiency and ensuring the integrity of the leveled concrete. However, a drawback is that during processing, when different heights are required, the device cannot be adjusted accordingly, limiting its use. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0025] Please see Figures 1-4 As shown, this utility model is a concrete leveling device for concrete pouring, including a support assembly 1, a height adjustment assembly 2 installed at the middle limit of the support assembly 1, an angle adjustment support assembly 3 fixedly installed on the front side of the height adjustment assembly 2, and a scraper assembly 4 fixedly installed on the front side of the angle adjustment support assembly 3.
[0026] The height adjustment assembly 2 includes an electrically controlled rotating mechanism 201, which is fixedly installed in the middle of the top of the mounting plate 103 by a bracket, and a threaded rod 202 is fixedly installed at the bottom of the electrically controlled rotating mechanism 201. A lifting support plate 203 is installed on the outside of the threaded rod 202 by a threaded limit.
[0027] By fixing the height adjustment component 2 to the rear of the device, the device can be used to perform the corresponding leveling work when leveling different types of building concrete, ensuring the flexibility of the work.
[0028] The bracket assembly 1 includes mounting side plates 101, with a mounting top plate 103 fixedly mounted at the top center of the two side mounting side plates 101, and a reinforcing support plate 102 fixedly mounted at the bottom of the two side mounting side plates 101. Meanwhile, a limit slide rail 104 is fixedly mounted on the inner wall of the mounting side plates 101.
[0029] The outer walls of the two lifting support plates 203 are slidably mounted on the limiting slide rail 104 via sliders. The electrically controlled rotating mechanism 201 in the height adjustment assembly 2 is installed in the middle of the top of the mounting plate 103. When the electrically controlled rotating mechanism 201 is working, it drives the threaded rod 202 at the bottom to rotate. Since the lifting support plates 203 are limited and mounted on the outside of the threaded rod 202 via threads, and the outer walls of the two lifting support plates 203 are slidably mounted on the limiting slide rail 104 of the bracket assembly 1 via sliders, the rotation of the threaded rod 202 will cause the lifting support plates 203 to slide up and down along the limiting slide rail 104, thereby realizing the adjustment of the overall height of the scraper plate assembly 4.
[0030] The angle adjustment bracket assembly 3 includes a mounting frame 301. A vertical pneumatic push rod 302 is hinged to the front side of the mounting frame 301, and a mounting frame 303 is fixedly mounted to the front side of the mounting frame 301. Scissor hinges 304 are rotatably mounted on both sides of the front end of the mounting frame 303 via a pivot. A bidirectional horizontal pneumatic push rod 305 is hinged to one side of the front wall of the mounting frame 303. The inner wall of the scissor hinge 304 is hinged to the end of the vertical pneumatic push rod 302. The end of the bidirectional horizontal pneumatic push rod 305 is hinged to a connecting seat 306. The connecting seat 306 is hinged to the front end of the scissor hinge 304. In the angle adjustment bracket assembly 3, the vertical pneumatic push rod 302 is mounted on the front side of the mounting frame 301, and the bidirectional horizontal pneumatic push rod 305 is mounted on one side of the front wall of the mounting frame 303. The extension and retraction of the vertical pneumatic push rod 302 can drive the scissor hinge 304, which is hinged to it, to rotate around the pivot at the front end of the mounting frame 303, thereby adjusting the angle of the scraper assembly 4 in the vertical direction. The extension and retraction of the bidirectional horizontal pneumatic push rod 305 can pull the scissor hinge 304 through the connecting seat 306, thereby changing the angle of the scraper assembly 4 in the horizontal direction to adapt to different concrete leveling requirements.
[0031] Mounting frame 301 is fixedly installed on the front outer wall of the lifting support plate 203.
[0032] The screed plate assembly 4 includes a brake scraper 401, which is fixedly installed on the front outer wall of the connecting seat 306. The brake scraper 401 is semi-circular in shape. A non-stick surface 402 is fixedly installed on the inner wall of the brake scraper 401. A silicone scraper 404 is fixedly installed on one outer wall of the brake scraper 401, and a flattening component 403 is fixedly installed on the other outer wall of the brake scraper 401. The brake scraper 401 of the screed plate assembly 4 is installed on the front side of the connecting seat 306. The non-stick surface 402 on its inner wall can prevent concrete from sticking. The silicone scraper 404 on one side is used to initially smooth the concrete surface, while the flattening component 403 on the other side compacts the smoothed concrete surface, so that the concrete surface achieves a flat and dense effect.
[0033] The concrete leveling device for concrete pouring mainly uses the support assembly 1 for stable support, the height adjustment assembly 2 to adjust the height of the scraper assembly 4, and the angle adjustment support assembly 3 to change the working angle of the scraper assembly 4, thereby leveling the concrete surface. The electric control motor 201 in the height adjustment assembly 2 is installed in the middle of the top of the mounting plate 103. When the electric control motor 201 is working, it drives the threaded rod 202 at the bottom to rotate. Since the lifting support plate 203 is installed on the outside of the threaded rod 202 through threaded limit, and the outer walls of the two lifting support plates 203 are slidably installed on the limit slide rail 104 of the support assembly 1 through sliders, the rotation of the threaded rod 202 will cause the lifting support plate 203 to slide up and down along the limit slide rail 104, thereby realizing the adjustment of the overall height of the scraper assembly 4. In the angle adjustment support assembly 3, the vertical pneumatic push rod 302 is installed on the front side of the mounting frame one 301, and the bidirectional horizontal pneumatic push rod 305 is installed on one side of the front wall of the mounting frame two 303. The extension and retraction of the vertical pneumatic push rod 302 can drive the scissor hinge 304, which is hinged to it, to rotate around the pivot at the front end of the mounting frame 2 303, thereby adjusting the angle of the scraper assembly 4 in the vertical direction. The extension and retraction of the bidirectional horizontal pneumatic push rod 305 can pull the scissor hinge 304 through the connecting seat 306, thereby changing the angle of the scraper assembly 4 in the horizontal direction to adapt to different concrete leveling requirements. The brake scraper 401 of the scraper assembly 4 is installed on the front side of the connecting seat 306. The non-stick surface 402 on its inner wall can prevent concrete from sticking. The silicone scraper 404 on one side is used to initially scrape the concrete surface, while the flattening component 403 on the other side compacts the scraped concrete surface, so that the concrete surface achieves a flat and dense effect. In the working process, the reinforcing support plate 102 at the bottom of the mounting side plates 101 on both sides is placed firmly in a suitable position in the concrete pouring operation area to complete the installation of the support assembly 1.Check the connections of the electric control motor 201, threaded rod 202, and lifting support plate 203 in the height adjustment assembly 2. Ensure that all pneumatic push rods and hinges in the angle adjustment bracket assembly 3 are properly connected. Ensure that the brake scraper 401, non-stick surface 402, silicone scraper 404, and flattening assembly 403 of the scraper plate assembly 4 are securely installed. Connect the power supply and prepare to begin work. Based on the concrete pouring height and flatness requirements, start the electric control motor 201. The electric control motor 201 drives the threaded rod 202 to rotate, causing the lifting support plate 203 to move up and down along the limit slide rail 104 until the scraper plate assembly 4 is adjusted to the appropriate working height. Then, turn off the electric control motor 201 to fix the height. Based on the actual condition of the concrete surface, first activate the vertical pneumatic push rod 302, and adjust the angle of the scissor hinge 304 by extending and retracting it to allow the brake scraper 401 to reach a suitable tilt angle in the vertical direction. Then, activate the bidirectional horizontal pneumatic push rod 305 to adjust the angle of the brake scraper 401 in the horizontal direction, completing the setting of the working angle of the scraper plate assembly 4. This pushes the device to move on the concrete pouring surface. The silicone scraper 404 on one side of the brake scraper 401 first performs preliminary scraping of the concrete surface, removing excess concrete. Next, the flattening assembly 403 on the other side of the brake scraper 401 compacts the scraped concrete surface, making it flat and dense. During operation, the height adjustment assembly 2 and angle adjustment bracket assembly 3 can be readjusted according to the flatness of the concrete surface to ensure optimal flatness. After completing the concrete flattening operation, turn off all pneumatic push rods and the electric control motor 201, move the device to the designated storage location, clean the residual concrete on the scraper plate assembly 4, and perform equipment maintenance for future use.
