Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a self-leveling auxiliary paving device. Background Technology

[0002] The self-leveling technology results in a floor that is environmentally friendly and highly flat, but it requires the use of a leveling device during construction.

[0003] A search revealed an existing technology for an auxiliary laying device for self-leveling ceramic flooring (publication number: CN220080680U). The auxiliary laying device includes: an auxiliary laying body, a horizontal rectangular pressure plate, a central control rod, and a backward-tilting outer sleeve. The structure of the auxiliary laying body is as follows: the front and rear ends of the horizontal rectangular plate are integrated with the horizontal columnar leveling part based on the vertical plate-shaped connecting part, respectively; a circular through hole is opened at the center of the horizontal rectangular plate, and the backward-tilting outer sleeve is integrated with the horizontal rectangular plate based on the circular through hole; the central control rod, located in the backward-tilting outer sleeve, passes through the circular through hole and is integrated with the horizontal rectangular pressure plate below the horizontal rectangular plate; the end of the central control rod is provided with an external threaded fixing part and a rotation adjustment device, and the end of the outer sleeve is provided with an internal threaded fixing part that matches the external threaded fixing part; a detachable ring-shaped fixing part is provided between the rotation adjustment device and the internal threaded fixing part.

[0004] In existing technologies, the position of the scraper is fixed and perpendicular to the direction of travel of the main body. This makes it difficult for the scraper to guide the material to one side of the main body according to the site. The perpendicular method will cause the scraper to push the material on one side to the scraped position, forming a bulge, which will affect the construction effect.

[0005] To address this, we propose a self-leveling auxiliary paving device. Utility Model Content

[0006] The present invention mainly solves the technical problem of the difficulty in adjusting the position of the scraper, and provides a self-leveling auxiliary paving device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a self-leveling auxiliary paving device, comprising:

[0008] The vehicle body has rollers rotatably connected to its bottom and pull rods rotatably connected to its side walls, with handles for gripping fixedly installed on the pull rods;

[0009] A leveling structure is installed on one side of the vehicle body for smoothing materials. The leveling structure includes a large arm, a scraper, a vertical shaft, and a pressure rod. The large arm is vertically adjustable and installed on the top of the vehicle body. The vertical shaft is fixedly connected to the scraper and rotatably connected to the large arm. The pressure rod is elastically installed on the top surface of the large arm and can engage with the scraper to lock the angle of the scraper.

[0010] In a preferred embodiment of this utility model, the pull rod forms a U-shaped frame, and the pull rod is rotatably connected to the vehicle body via a pin.

[0011] In a preferred embodiment of this utility model, the upper arm forms a rod with a horizontal cross-section in the shape of a T. The upper arm has a through-hole, and the vertical shaft is rotatably disposed in the through-hole. The vertical shaft is secured with a retaining spring to prevent it from detaching.

[0012] In a preferred embodiment of this utility model, the scraping structure further includes a thrust hole and an insert rod. The insert rod is fixedly connected to the pressure rod, and several thrust holes are provided on the top of the scraper. The insert rod can be inserted into the insert rod.

[0013] In a preferred embodiment of this utility model, the thrust holes are arranged in a circular array with the vertical axis as the center. The thrust holes are circular holes, and the insert rod is fixedly installed at the bottom of the pressure rod. The insert rod is adapted to the thrust holes.

[0014] In a preferred embodiment of this utility model, the scraping structure further includes a guide rod, which is fixedly installed on the top of the upper arm. The pressure rod is slidably connected to the guide rod, and a spring is provided on the pressure rod. The spring is sleeved on the guide rod, and a circular plate is fixedly installed on the upper end of the guide rod, with the upper end of the spring abutting against the bottom of the circular plate.

[0015] In a preferred embodiment of this utility model, two limiting rods and an adjusting screw are fixedly installed on the top of the vehicle body. The boom is slidably connected to the limiting rods, and a locking nut is threaded onto the adjusting screw, which can lock the boom.

[0016] In a preferred embodiment of this utility model, the main arm has two sliding holes for matching the limiting rods. The limiting rods are slidably disposed in the sliding holes. The two limiting rods are symmetrically distributed with the adjusting screw. The main arm also has an adjusting hole for the adjusting screw to pass through. The adjusting screw passes through the adjusting hole, and two locking nuts are located at the top and bottom of the main arm, respectively.

[0017] This utility model provides a self-leveling auxiliary paving device. It has the following beneficial effects:

[0018] 1. This self-leveling auxiliary paving device, by lifting the pressure rod, moves the insertion rod upward. After rotating the scraper to the appropriate position, releasing the pressure rod resets it, causing the insertion rod to engage with the corresponding thrust hole, thereby adjusting and locking the angle of the scraper. Combined with the pull rod, it allows the vehicle to be moved by pushing or pulling. The angle of the scraper adapts to the pushing and pulling of the vehicle, ensuring convenient construction and effective material leveling. The inclined scraper provides lateral squeezing force to the material, promoting material flow and improving the leveling effect. A rotatable pull rod allows for adjusting the handle position, enabling flexible adjustment to both sides of the vehicle, thus pushing or pulling the vehicle. This allows for selection of the vehicle movement method based on the construction site, providing greater flexibility in use.

[0019] 2. This self-leveling auxiliary paving device uses a spring to apply downward pressure to the pressure rod, forcing the insertion rod into the thrust hole. Locking can be achieved by lifting the pressure rod and then releasing it, simplifying operation and facilitating adjustment of the scraper angle.

[0020] 3. This self-leveling auxiliary paving device allows for adjustment of the scraper height by loosening the locking nuts, raising the main arm, sliding the main arm radially along two limiting rods, and then tightening the locking nuts. The two locking nuts clamp and fix the height of the main arm, thereby enabling adjustment of the scraper's paving thickness within a certain range. This provides greater controllability and adjustability for leveling construction. Attached Figure Description

[0027] A self-leveling auxiliary paving device, such as Figure 1 and Figure 3 As shown, it includes:

[0028] The vehicle body 10 has rollers rotatably connected to its bottom and a pull rod 11 rotatably connected to its side wall. The pull rod 11 is fixedly equipped with a handle 12 for gripping. The pull rod 11 forms a U-shaped frame and is rotatably connected to the vehicle body 10 via a pin. By setting a rotatable pull rod 11, the position of the handle 12 can be adjusted by rotating the pull rod 11, so that the handle 12 can be flexibly adjusted to both sides of the vehicle body 10, thereby realizing the pushing or pulling of the vehicle body 10. This allows for the selection of the method of moving the vehicle body 10 according to the construction site, and the flexibility of use is greater.

[0029] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a leveling structure is installed on one side of the vehicle body 10 for smoothing materials. The leveling structure includes a large arm 20, a scraper 21, a vertical shaft 22, and a pressure rod 23. The large arm 20 is vertically and flexibly mounted on the top of the vehicle body 10. The vertical shaft 22 is fixedly connected to the scraper 21 and rotatably connected to the large arm 20. The pressure rod 23 is elastically mounted on the top surface of the large arm 20 and can engage with the scraper 21 to lock the angle of the scraper 21. The large arm 20 forms a horizontal T-shaped rod. The scraper has a shaft hole, and the vertical shaft 22 is rotatably installed in the shaft hole. The vertical shaft 22 is snapped with a snap ring to prevent it from falling off. The scraping structure also includes a thrust hole 24 and a rod 25. The rod 25 is fixedly connected to the pressure rod 23. Several thrust holes 24 are opened on the top of the scraper 21. The rod 25 can be inserted into the rod 25. The thrust holes 24 are arranged in a circular array with the vertical shaft 22 as the center. The thrust holes 24 are round holes. The rod 25 is fixedly installed at the bottom of the pressure rod 23. The rod 25 is adapted to the thrust holes 24.

[0030] In this scheme, in order to adjust the angle between the scraper 21 and the vehicle body 10 and thus adjust the angle at which the scraper 21 scrapes the raw material, the pressure rod 23 is lifted, which drives the insertion rod 25 to move upward. After the scraper 21 is rotated to adjust to the appropriate position, the pressure rod 23 is released, and the pressure rod 23 is reset, so that the insertion rod 25 is inserted into the thrust hole 24 at another corresponding position. This achieves the adjustment and locking of the angle of the scraper 21. In conjunction with the pull rod 11, the vehicle body 10 is moved by pushing or pulling. The angle change of the scraper 21 adapts to the pushing and pulling of the vehicle body 10, ensuring the convenience of construction and the leveling effect of the material. Since the inclined scraper 21 will give the material a lateral squeezing force, it will promote the flow of the material and improve the leveling effect.

[0031] like Figure 5As shown, the scraping structure also includes a guide rod 26, which is fixedly installed on the top of the boom 20. The pressure rod 23 is slidably connected to the guide rod 26. A spring is provided on the pressure rod 23, and the spring is sleeved on the guide rod 26. A circular plate is fixedly installed on the upper end of the guide rod 26, and the upper end of the spring abuts against the bottom of the circular plate. As a supplementary explanation of the above scheme, in order to achieve the elastic connection of the pressure rod 23, the spring applies downward pressure to the pressure rod 23 to force the insertion rod 25 into the thrust hole 24. Locking can be achieved by lifting the pressure rod 23 and then releasing the pressure rod 23, which simplifies the operation and facilitates the adjustment of the scraper 21 angle.

[0032] like Figure 4 As shown, two limiting rods 30 and an adjusting screw 31 are fixedly installed on the top of the vehicle body 10. The upper arm 20 is slidably connected to the limiting rods 30. A locking nut 32 is threaded onto the adjusting screw 31. The locking nut 32 can lock the upper arm 20. The upper arm 20 has two sliding holes adapted to the limiting rods 30. The limiting rods 30 are slidably disposed in the sliding holes. The two limiting rods 30 are symmetrically distributed with respect to the adjusting screw 31. The upper arm 20 also has an adjusting hole for the adjusting screw 31 to pass through. The adjusting screw 31 passes through the adjusting hole. The two locking nuts 32 are located above and below the upper arm 20, respectively.

[0033] In this solution, by loosening the locking nut 32, the boom 20 is lifted and slides radially along the two limiting rods 30. Then, the locking nut 32 is tightened, and the two locking nuts 32 clamp and fix the height of the boom 20, thereby adjusting the height of the scraper 21. As a result, the thickness of the scraper 21 can be adjusted within a certain range, which makes the leveling construction more controllable and adjustable.

[0034] The working principle of this utility model is as follows: Lifting the pressure rod 23 causes the insertion rod 25 to move upwards. After rotating the scraper 21 to a suitable position, the pressure rod 23 is released. A spring then applies downward pressure to the pressure rod 23, forcing the insertion rod 25 into the thrust hole 24, thus adjusting and locking the angle of the scraper 21. The pull rod 11 is rotated to adjust the position of the handle 12, allowing it to be flexibly adjusted to both sides of the vehicle body 10, thereby pushing or pulling the vehicle body 10. Loosening the locking nut 32 and lifting the upper arm 20 causes it to slide radially along the two limiting rods 30. Then, the locking nut 32 is tightened, clamping and fixing the height of the upper arm 20, thus adjusting the height of the scraper 21. This allows the scraping thickness of the scraper 21 to be adjusted within a certain range. Pushing or pulling the vehicle body 10 on the ground allows the scraper 21 to scrape the material flat.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
