Description

Technical Field

[0001] This utility model relates to the field of precast concrete production technology, specifically to a mud leveling device for precast concrete production. Background Technology

[0002] Precast concrete refers to concrete products manufactured in a factory or on-site (not at the final design location). In the prior art, a patent with authorization announcement number CN214293622U and titled "A Fixing Device for Concrete Component Production" includes a fixing platform. A mold box is placed on top of the fixing platform. The fixing platform has a threaded cavity inside, and a threaded rod is movably fitted inside the threaded cavity. Both ends of the threaded rod penetrate the interior of the fixing platform and extend outwards. This fixing device for concrete component production connects the Y-axis clamping plate and the movable cavity into a single unit by locking a third connecting column inside a fixing groove. A fixing spring and a limiting ring generate clamping force in the opposite direction of the movable column's movement, fixing the front and rear sides of the mold box. Because there is more than one fixing groove, it can clamp concrete mold boxes of different sizes, solving the problem that existing fixing devices cannot adapt to different sizes of concrete component mold boxes, while also improving the fixing effect and having strong applicability. However, in actual use, this fixing device for concrete component production is inconvenient for mold disassembly, requiring manual compaction and leveling of the concrete, resulting in low efficiency. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a mud leveling and smoothing device for precast concrete production.

[0004] The technical solution adopted by this utility model to solve its technical problem is a leveling and slurry scraping device for precast concrete production, including a support. Two baffles are fixed to the top of the support. A first hydraulic cylinder is fixed to each of the two baffles. Side plates are fixed to the piston rods of the two first hydraulic cylinders. The two side plates are located between the two baffles. A bottom plate is provided between the two side plates. A notch adapted to the bottom plate is provided on one side of the support. Brake rollers are installed at the four corners of the bottom end of the bottom plate. Two vertical plates are fixed to the top of the bottom plate. A support plate is provided above the bottom plate. The support plate is fixed to the top of the two baffles. A second hydraulic cylinder is fixed to the top of the support plate. A pressure plate is fixed to the bottom end of the piston rod of the second hydraulic cylinder. A bracket is provided on one side of the pressure plate. The bracket is connected to the two baffles. A third hydraulic cylinder is fixed to the side of the bracket away from the pressure plate. A scraper is fixed to the piston rod of the third hydraulic cylinder. The bottom end of the scraper is flush with the tops of the two side plates and the two vertical plates.

[0005] By adopting the above technical solution, concrete is poured into the space enclosed by the base plate, vertical plate, and side plate. The piston rod of the second hydraulic cylinder drives the pressure plate to move downward, and the pressure plate compacts the concrete. The piston rod of the second hydraulic cylinder drives the pressure plate to move upward, and the piston rod of the third hydraulic cylinder drives the scraper to move horizontally, which facilitates the leveling of the top of the concrete. After the concrete is formed, the piston rods of the two first hydraulic cylinders drive the two side plates to move away from the concrete, which is conducive to the demolding of the concrete and improves efficiency. The brake rollers, base plate, and two vertical plates facilitate the transfer of concrete.

[0006] Specifically, a base plate and a handrail are fixed to the side wall of the vertical plate away from the support. A collection box is provided at the top of the base plate. Handles are fixed on both sides of the collection box. Two insertion blocks are fixed at the bottom of the collection box. Two through slots that are adapted to the insertion blocks are provided on the base plate.

[0007] By adopting the above technical solution, the scraper flattens the top of the concrete, and the excess concrete is pushed into the collection box by the scraper, which facilitates the collection of excess concrete. The collection box can be removed from the base plate by holding the two handles and lifting it up.

[0008] Specifically, each of the two opposing sidewalls of the two side plates is fixed with four crossbars, and each of the two baffles is provided with four through holes that are adapted to the crossbars.

[0009] By adopting the above technical solution, the crossbar configuration can improve the stability of the side plate.

[0010] Specifically, two guide rods are fixed on the side of the scraper away from the pressure plate, two through holes adapted to the guide rods are provided on the bracket, two guide plates are fixed on the top of the pressure plate, and two through grooves adapted to the guide plates are provided on the support plate.

[0011] By adopting the above technical solutions, the setting of the guide rod can improve the stability of the scraper, and the setting of the guide plate can improve the stability of the pressure plate.

[0012] Specifically, multiple reinforcing blocks are fixed to the opposite sidewalls of the two vertical plates, and the bottom ends of the multiple reinforcing blocks are connected to the base plate.

[0013] By adopting the above technical solution and setting up the reinforcing blocks, the stability of the vertical plate can be improved.

The bottom of the scraper 7 is flush with the top of the two side plates 13 and the two vertical plates 14.

[0024] In use, concrete is poured into the space enclosed by the base plate 15, vertical plate 14, and side plate 13. The concrete is vibrated using a vibrator (existing technology). After vibration, the piston rod of the second hydraulic cylinder 9 drives the pressure plate 12 to move downward, and the pressure plate 12 compacts the concrete. The piston rod of the second hydraulic cylinder 9 drives the pressure plate 12 to move upward, and the piston rod of the third hydraulic cylinder 6 drives the scraper 7 to move horizontally, which facilitates the leveling of the top of the concrete. After the concrete is formed, the piston rods of the two first hydraulic cylinders 3 drive the two side plates 13 to move away from the concrete, which facilitates the demolding of the concrete and improves efficiency. The brake rollers, base plate 15, and two vertical plates 14 facilitate the transfer of concrete.

[0025] To facilitate the collection of excess concrete, for example, such as Figure 1 , Figure 3 As shown, a base plate 16 and a handrail 20 are welded and fixed to the side wall of the vertical plate 14 away from the bracket 5. A collection box 17 is provided at the top of the base plate 16. Handles are welded and fixed to both sides of the collection box 17.

[0030] In use, concrete is poured into the space enclosed by the base plate 15, the vertical plate 14 and the side plate 13. The concrete is vibrated using a vibrator (existing technology). After vibration, the piston rod of the second hydraulic cylinder 9 drives the pressure plate 12 to move down, and the pressure plate 12 compacts the concrete.

[0031] The piston rod of the second hydraulic cylinder 9 drives the pressure plate 12 to move upward, and the piston rod of the third hydraulic cylinder 6 drives the scraper 7 to move horizontally, which facilitates the leveling of the top of the concrete. Excess concrete is pushed into the collection box 17 by the scraper 7, which facilitates the collection of excess concrete. By holding the two handles and lifting the collection box 17, the collection box 17 can be removed from the base plate 16.

[0032] After the concrete is formed, the piston rods of the two first hydraulic cylinders 3 drive the two side plates 13 to move away from the concrete, which facilitates the demolding of the concrete and improves efficiency. The brake rollers, the bottom plate 15 and the two vertical plates 14 facilitate the transfer of the concrete.
