Description

Technical Field

[0001] This application relates to the field of concrete, and in particular to concrete leveling devices for building construction. Background Technology

[0002] In concrete leveling, the aim is to treat structural layers such as building floors and slabs to obtain a smooth and dense surface. After the material is laid, tools are needed to level it. An electric leveling screed is a typical tool, its core being a screed equipped with a top-mounted vibrating motor. During operation, the vibrating motor starts, giving the screed high-frequency vibration capability, thereby vibrating and leveling the concrete surface.

[0003] Existing technology includes an electric leveling ruler capable of changing length, such as Chinese patent application number CN202520783204.0, which includes a fixed component, two rotating components, a vibration motor, and a gripping plate. The two rotating components are respectively rotatably mounted at both ends of the fixed component. In this utility model, by setting the fixed component and the two rotating components, if the length and width of the concrete area to be leveled are both small, the screw can be rotated by turning the knob, which in turn drives the connecting rod and the two insert rods to slide upward to unlock the two auxiliary vibration plates. Then, the two auxiliary vibration plates are rotated clockwise until they are in contact with the sides of the main vibration plate. Then, the knob is reversed, which drives the insert rods to slide downward and lock the two auxiliary vibration plates again, thereby reducing the overall length and leveling concrete areas with both small length and width.

[0004] However, the existing technology, including the aforementioned patent, has the following problems: the vibration motor is fixed on the top of the main vibrating plate, and the vibration is directly transmitted to the concrete surface through the main vibrating plate. This design can ensure uniform vibration distribution, but the shaking when handheld may directly affect the leveling effect, especially during long-term operation, which can easily lead to fatigue and further affect stability; and the vibration between the secondary vibrating plate and the main vibrating plate is only transmitted through the hinge, so the vibration cannot be effectively transmitted to the secondary vibrating plate.

[0005] Therefore, there is an urgent need to design a concrete leveling device to solve the above-mentioned technical problems. Utility Model Content

[0006] To address the problems of fatigue and reduced leveling effect caused by hand-held operation, as well as the inability of the main and auxiliary vibrating plates to effectively transmit vibration, this utility model proposes a leveling device for building concrete, the technical solution of which is as follows.

[0007] A concrete leveling device includes: a main vibrating plate with its bottom for contacting the concrete surface; a vibration device fixedly installed on the top of the main vibrating plate; a gripping rod with one end rotatably connected to the top of the main vibrating plate; a traveling wheel assembly disposed on one side of the main vibrating plate in the width direction, including a pair of height-adjustable traveling wheels, the rotation direction of the traveling wheels being perpendicular to the length direction of the main vibrating plate, the traveling wheels including a hub and a plurality of wheel spikes radially distributed around the hub; and a vibration extension mechanism disposed on both sides of the top of the main vibrating plate along the length direction for detachably installing a secondary vibrating plate, the secondary vibrating plate extending along the length direction of the main vibrating plate.

[0008] Furthermore, the main vibrating plate is bent upwards on the side near the walking wheel assembly to form an arc surface.

[0009] Furthermore, the walking wheel assembly includes a pair of mounting rods, which are fixed to the side of the main vibration plate and extend obliquely upward before bending vertically downward to form a vertical section. The vertical section has several positioning holes, and the walking wheel can be detachably installed in the positioning holes at different heights through the wheel axle to adjust the height.

[0010] Furthermore, the vibration expansion mechanism includes mounting strips symmetrically arranged on the top of the main vibration plate. The mounting strips have a blind mounting hole coaxially opened on the side away from the opposite mounting strip. The mounting hole is parallel to the length direction of the main vibration plate. A mounting rod is fixedly installed on the top of the secondary vibration plate. The mounting rod can be slidably inserted into the mounting hole. The mounting strip is provided with a fixing structure, which can fix the mounting rod.

[0011] Furthermore, the fixing mechanism includes several threaded holes perpendicular to its own axis at the top of the mounting strip, and several fastening grooves are provided on the mounting rod. The bolt is screwed into the threaded hole and radially pushed into the fastening groove to lock the mounting rod.

[0012] Furthermore, the end of the wheel spike is arc-shaped, and the body of the wheel spike is conical.

[0013] Furthermore, the grip rod is a telescopic rod, and one end of the grip rod is rotatably connected to a pair of rotating ears provided on the main vibrating plate via a rotating shaft. The rotating ears are provided with a plurality of first fixing holes along an arc shape, and the arc shape is concentric with the rotation direction of the fixing sleeve rod. The grip rod is provided with a second fixing hole, and both the first fixing hole and the second fixing hole are through holes. A fixing pin is inserted coaxially into the first fixing hole and the second fixing hole to fix the angle of the grip rod.

[0014] The beneficial effects of this utility model are as follows: This utility model addresses the problems of hand fatigue and ineffective vibration transmission between the main and auxiliary vibrating plates by introducing a walking wheel assembly to reduce the operator's burden and improve the stability of leveling; the vibration extension mechanism realizes efficient vibration transmission between the main and auxiliary vibrating plates, ensuring a uniform and flat concrete surface; at the same time, the height-adjustable walking wheels, detachable auxiliary vibrating plates, and rotatable and telescopic gripping rod enhance the adaptability and operability of the device, thereby improving overall construction efficiency and quality, reducing fatigue, and optimizing the leveling effect.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, a concrete leveling device for construction includes: a main vibrating plate 1, the bottom of which is used to contact the concrete surface;

[0024] like Figure 1 , Figure 2 As shown, the vibration device 2 is fixedly installed on the top of the main vibration plate 1. In this embodiment, a vibration motor is selected. The vibration motor is only marked in the figure and the specific structure is not drawn. Moreover, there are mature existing solutions for the installation and connection of the vibration motor, so they will not be described in detail.

[0025] like Figure 1 , Figure 2 , Figure 4As shown, the grip rod 3 has one end rotatably connected to the top of the main vibrating plate 1, allowing the operator to easily grip and adjust the device angle, reducing hand fatigue during long-term operation. Preferably, the grip rod 3 is a telescopic rod, which can be extended to a fixed length. This type of telescopic rod adopts a relatively mature solution in the prior art, so it will not be described in detail here. One end of the grip rod 3 is rotatably connected to a pair of rotating ears 16 provided on the main vibrating plate 1 via a rotating shaft 17. Several first fixing holes 18 are provided on the rotating ears 16 along an arc shape. The arc shape is concentric with the rotation direction of the fixing sleeve rod. The grip rod 3 is provided with a second fixing hole 19. Both the first fixing hole 18 and the second fixing hole 19 are through holes. A fixing pin is inserted coaxially into the first fixing hole 18 and the second fixing hole 19 to fix the angle of the grip rod 3.

[0026] like Figure 1 , Figure 2 As shown, the traveling wheel assembly is located on one side of the main vibrating plate 1 in the width direction and includes a pair of height-adjustable traveling wheels. The rotation direction of the traveling wheels is perpendicular to the length direction of the main vibrating plate 1. The traveling wheel includes a hub 4 and several wheel spikes 5 radially distributed around the hub 4. Preferably, the traveling wheel assembly includes a pair of mounting rods 9. The mounting rods 9 are fixed to the side of the main vibrating plate 1 and extend obliquely upwards before bending vertically downwards to form a vertical section. Several positioning holes 10 are opened in the vertical section. The traveling wheel can be detachably installed in the positioning holes 10 at different heights through the wheel axle 11 to adjust the height, which facilitates quick adjustment of the traveling wheel height and adapts to different concrete thicknesses or uneven ground conditions.

[0027] like Figure 1 , Figure 2 As shown, preferably, the main vibrating plate 1 is bent upward on the side near the walking wheel assembly to form an arc surface 15, which prevents concrete from overflowing or accumulating during movement and improves the smoothness of leveling.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4A vibration extension mechanism is provided on both sides of the top of the main vibrating plate 1 along its length, for detachably mounting the auxiliary vibrating plate 6, which extends along the length of the main vibrating plate 1. Preferably, the vibration extension mechanism includes mounting strips 7 symmetrically arranged on the top of the main vibrating plate 1. A blind mounting hole 12 is coaxially formed on the side of the mounting strip 7 away from the opposite mounting strip. The mounting hole is parallel to the length of the main vibrating plate 1. A mounting rod 8 is fixedly mounted on the top of the auxiliary vibrating plate 6. The mounting rod 8 can be slidably inserted into the mounting hole, and a fixing structure is provided on the mounting strip 7 to fix the mounting rod 8. Preferably, the fixing mechanism includes several threaded holes 13 perpendicular to its own axis at the top of the mounting strip 7. Several fastening grooves 14 are formed on the mounting rod 8. Bolts are screwed into the threaded holes 13 and radially pushed into the fastening grooves 14 to lock the mounting rod 8. Install blind hole 12, install insert rod 8 and bolt fixing system (threaded hole 13 and fastening groove 14) to ensure that the auxiliary vibration plate 6 is firmly installed, avoids loosening during vibration, and ensures vibration transmission efficiency.

[0029] like Figure 1 , Figure 5 As shown, preferably, the end of the wheel spike 5 is arc-shaped and the body of the wheel spike 5 is conical. The wheel spike 5 is designed differently from ordinary rubber wheels, which reduces the contact area with concrete and the disturbance range is smaller. In this embodiment, the wheel spike 5 is made of stainless steel, which is corrosion-resistant and abrasion-resistant.

[0030] Overall usage summary:

[0031] During operation, the operator controls the device via the grip rod 3. The walking wheel assembly supports the movement of the device on the concrete surface, and the wheel spikes 5 provide stable grip and longitudinal support. The user only needs to hold the grip rod 3 for support. It should be noted that the overall direction of movement of this device should be from the vibrating device 2 to the mounting rod 9, so as to smooth out the movement marks of the walking wheel assembly in the concrete. After the vibrating device 2 is started, the main vibrating plate 1 vibrates and scrapes the concrete. The auxiliary vibrating plate 6 is installed through the vibration extension mechanism to expand the scraping range, and the bolt fixing ensures effective vibration transmission. The height of the walking wheels can be adjusted through the positioning holes 10 to adapt to different concrete thicknesses. The extension and angle adjustment of the grip rod 3 optimizes the operating comfort. Overall, the device moves smoothly, reduces hand fatigue, and achieves efficient and uniform concrete scraping operation.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
