Description

Technical Field

[0001] This invention belongs to the technical field of ground leveling equipment, specifically relating to a ground leveling device for concrete floor paving. Background Technology

[0002] Fluidized paving is widely used in building and decoration construction, such as concrete paving of roads and mortar paving before installing wood flooring in interior decoration. In particular, concrete paving before installing wood flooring in interior decoration requires a high degree of flatness.

[0003] However, this leveling equipment has the following problems in practical use: Currently, the leveling method after concrete is laid is to use a spirit level. However, the spirit level has a limited length and cannot measure the flatness of the concrete surface along its length, resulting in inaccurate measurement data. Furthermore, impurities are left on site after the concrete is laid, and the equipment cannot directly contact the concrete surface when moving towards the ground, thus causing inaccurate testing.

[0004] Therefore, it is necessary to provide a ground leveling device for concrete floor paving to solve the above-mentioned technical problems. Summary of the Invention

[0009] In a concrete floor leveling device provided by the present invention, a base frame is provided below the base, and the base frame is respectively provided at both ends of the base. The base frames on both sides are Y-shaped with the base, and rollers are provided on both sides of the base frame.

[0010] In a concrete floor leveling device provided by the present invention, a first pulley is provided on the roller of one side of the base frame, and a third pulley is provided on the roller of the other side of the base frame.

[0013] In a concrete floor leveling device provided by the present invention, an inner platform is provided on the base, and a rotating rod is rotatably connected to the inner platform. The rotating rod is welded below a large gear, and the large gear is detachably connected to the bottom of a top seat. A small gear is meshed with one side of the large gear, and the small gear is located at the output end of a third motor. The third motor is detachably connected to the inner platform of the base.

[0014] In a concrete floor leveling device provided by the present invention, the fixed frame is set below the movable seat via a support rod. A mounting seat is provided below the movable seat, and an mounting groove is formed inside the mounting seat. A measuring tape spring is embedded inside the mounting groove. A connecting rod is rotatably connected to the middle of the measuring tape spring. A slot is formed on the connecting rod, and one end of the measuring tape spring is connected to the slot. A housing is detachably connected to the mounting seat. One end of the connecting rod passes through the housing and is located on the outside.

[0015] Compared with related technologies, the concrete floor leveling device provided by the present invention has the following advantages: This invention provides a floor leveling device for concrete floor paving. The device comprises a first motor mounted on a top base, connected to a lead screw, and a movable base connected to the lead screw. The first motor controls the movable base to reciprocate on the lead screw. The movable base has side frames, each with a limiting slot. A horizontal bar can be installed in each limiting slot, allowing the horizontal bar to move vertically up and down within the slot. The tops of both horizontal bars are mounted on a linkage plate, which simultaneously moves the horizontal bars up and down. The two horizontal bars are horizontal to each other and at the same height. The linkage plate is connected to a cylinder on the movable base, which moves the linkage plate up and down during testing. During this up-and-down movement, the horizontal bars on both sides... The horizontal bar will simultaneously contact the ground. Due to the relatively long overall length of the movable seat and side frame, the levelness of the concrete paving at different locations can be detected. If the top seat remains level, the horizontal bars on both sides will directly reflect whether the ground is flat when they contact the ground, thus quickly detecting the flatness of the concrete paving at different locations, thereby improving construction efficiency. A linkage rod is installed below the movable seat, and a pull rope is installed on the linkage rod. The other end of the pull rope is connected to the horizontal bar. When the horizontal bar moves down, it will drive the linkage rod to rotate. When the linkage rod rotates, it will drive the lever to rotate through the chain. When the lever rotates, it can sweep the ground below the horizontal bar, thereby exposing the concrete ground. This setting ensures the accuracy of the detection results.

[0016] This invention provides a ground leveling device for concrete floor paving. The device consists of a base frame with rollers mounted on it. These rollers are connected to a second pulley on a second motor via corresponding first and third pulleys. The second motor then moves the device to the desired inspection location. An inner platform is mounted on the base, and a third motor is mounted on the inner platform. A small gear connected to the third motor meshes with a large gear on a top seat, allowing the third motor to control the rotation of the top seat. This enables the leveling rod to inspect different locations. Compared to manual inspection at different locations, this solution is more time-saving and labor-saving, reducing the workload for personnel. Attached Figure Description

[0019] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings. Typical embodiments of the present invention are shown in the drawings.

[0020] Example 1: As Figure 1 As shown, a concrete floor leveling device for concrete floor paving according to the present invention includes a base 1, rollers 19, a first motor 2, and a lead screw 15. A top seat 3 is provided at the top of the base 1. The first motor 2 is detachably connected to one side end face of the top seat 3. The output end of the first motor 2 is connected to the lead screw 15 at the other end of the top seat 3. A movable seat 4 is provided on the lead screw 15. Side frames 9 extend outward from both ends of the movable seat 4. A horizontal rod 14 is slidably connected to the side frames 9 in the vertical direction. The two horizontal rods 14 are horizontal. A linkage plate 13 is connected to the upper end of the horizontal rod 14. The linkage plate 13 is located at the output end of the cylinder 12. A fixed frame 25 is provided below the movable seat 4. A lever 28 is provided on both sides of the fixed frame 25. The lever 28 is respectively located below the horizontal rod 14. By providing a movable seat 4 on the top seat 3 and a movable horizontal rod 14 that can be raised and lowered on the movable seat 4, the levelness of different positions can be detected simultaneously when the horizontal rod 14 moves towards the ground, thereby eliminating the need for repeated detection and improving efficiency.

[0021] like Figure 2 As shown, the side frame 9 and the movable base 4 are arranged in a T-shape. Limiting ports 10 are opened on both sides of the side frame 9 of the movable base 4. A corresponding horizontal bar 14 is slidably connected in each limiting port 10. The cylinder 12 connected to the linkage plate 13 is vertically set at the top of the movable base 4. By setting the side frame 9, the horizontal bars 14 on both sides can be spaced further apart, so that the flatness of different positions can be reflected at the same time, thereby making the detection more accurate.

[0022] As an optional solution, in one embodiment of the present invention, such as Figure 3As shown, a threaded opening 11 is provided at the position of the lead screw 15 corresponding to the movable seat 4. The lead screw 15 is threaded into the threaded opening 11 of the movable seat 4. Guide rods 16 are respectively provided on the top seats 3 on both sides of the lead screw 15. The guide rods 16 are slidably connected to the corresponding movable seats 4. The guide rods 16 are parallel to the lead screw 15. The guide rods 16 can limit the movable seat 4, thereby preventing the movable seat 4 from rotating with the lead screw 15.

[0023] Example 2: Figure 4 , Figure 5 and Figure 6 As shown, based on Embodiment 1, the present invention provides a technical solution: a base frame 17 is provided below the base 1, with the base frames 17 respectively located at both ends of the base 1. The two base frames 17 and the base 1 are in a Y-shape. Rollers 19 are provided on both base frames 17, allowing the equipment to move. A first pulley 5 is provided on the roller 19 of one base frame 17, and a third pulley 7 is provided on the roller 19 of the other base frame 17. The first pulley 5 and the third pulley 7 are both located on the outside of the base frame 17, and are on the same side. This same-side arrangement allows the belt 8 to be connected. A second motor 18 is provided inside the base 1, with one end of the second motor 18 located on the outside of the base 1. A second pulley 6 is provided on the output end of the second motor 18. The second pulley 6 is located above the first pulley 5 and the third pulley 7, and can drive the roller 19 to rotate through the second motor 18. The first pulley 5, the second pulley 6, and the third pulley 7 are arranged in a triangle. The first pulley 5, the second pulley 6, and the third pulley 7 are connected to the belt 8, and the belt 8 can realize the linkage between the pulleys. An inner platform 20 is provided on the base 1. A rotating rod 21 is rotatably connected to the inner platform 20. The rotating rod 21 is welded below the large gear 22. The large gear 22 is detachably connected to the bottom of the top seat 3. A small gear 23 is meshed with one side of the large gear 22. The small gear 23 is located at the output end of the third motor 24. The third motor 24 is detachably connected to the inner platform 20 of the base 1. The transmission can be carried out through the meshing of the small gear 23 and the large gear 22, thereby controlling the rotation of the top seat 3.

[0024] As an optional solution, in this embodiment, such as Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the fixed frame 25 is mounted below the movable base 4 via a support rod 26. A mounting base 33 is located below the movable base 4. The mounting base 33 has an internal mounting groove 35, into which a measuring tape spring 36 is embedded. The middle of the measuring tape spring 36 is rotatably connected to a connecting rod 38. A slot 37 is formed on the body of the connecting rod 38. One end of the measuring tape spring 36 is connected to the slot 37. A housing 34 is detachably connected to the mounting base 33. One end of the connecting rod 38 passes through the housing 34 and is located on the outside. The outer end of the connecting rod 38 is connected to a linkage rod 32. The other end of the linkage rod 32 is rotatably connected to the fixed frame 25. The two sides of the fixed frame 25... The side lever 28 is rotatably connected to the fixed frame 25 via the movable rod 27. A side gear 29 is provided on one end of the movable rod 27. A main gear 30 is provided on the linkage rod 32 between the side gears 29. The main gear 30 and the side gear 29 are connected by a chain 31. A pull rope 39 is provided on the linkage rod 32. The other end of the pull rope 39 is connected to the horizontal rod 14. When the horizontal rod 14 moves down, the pull rope 39 can be pulled. When the pull rope 39 extends, it will drive the linkage rod 32 to rotate. When the linkage rod 32 rotates, it can drive the lever 28 to rotate through the chain 31. The lever 28 can sweep the ground, thereby preventing the horizontal rod 14 from being attached to debris and affecting the measurement.

[0025] The working principle of the concrete floor leveling device provided by this invention is as follows: Implementation steps for the first innovation point: Step 1: In this solution, a first motor 2 is installed on the top seat 3. The first motor 2 is connected to the lead screw 15, and the lead screw 15 is connected to the movable seat 4. The first motor 2 can control the movable seat 4 to reciprocate on the lead screw 15. The movable seat 4 is equipped with side frames 9, and each side frame 9 has a limit port 10. Step 2: A horizontal bar 14 can be installed in each limiting port 10. The horizontal bar 14 can move vertically up and down within the limiting port 10. The tops of the horizontal bars 14 on both sides are set on the linkage plate 13. The linkage plate 13 can simultaneously drive the horizontal bars 14 to move up and down. The horizontal bars 14 on both sides are horizontal to each other and have the same horizontal height. The linkage plate 13 is connected to the cylinder 12 of the moving seat 4. The cylinder 12 can drive the linkage plate 13 to move up and down during testing. Step 3: When moving up and down, the horizontal bars 14 on both sides will simultaneously contact the ground. Because the overall length of the moving seat 4 and the side frame 9 is relatively long, the level of concrete paving at different positions can be detected. If the top seat 3 remains horizontal, the horizontal bars 14 on both sides will directly reflect whether the ground is flat when they contact the ground, thus quickly detecting the levelness of concrete paving at different positions, thereby improving construction efficiency. A linkage rod 32 is set below the moving seat 4, and a pull rope 39 is set on the linkage rod 32. The other end of the pull rope 39 is connected to the horizontal bar 14. When the horizontal bar 14 moves down, it will drive the linkage rod 32 to rotate. When the linkage rod 32 rotates, it will drive the lever 28 to rotate through the chain 31. When the lever 28 rotates, it can sweep the ground below the horizontal bar 14, thereby exposing the concrete ground. This setting ensures the accuracy of the detection results.

[0026] Implementation steps for the second innovation point: Step 1: This solution involves setting a base frame 17 on the base 1, with rollers 19 on the base frame 17. The rollers 19 are connected to the second pulley 6 on the second motor 18 via the corresponding first pulley 5 and third pulley 7. Step 2: The second motor 18 can drive the equipment to the position to be tested. The base 1 is equipped with an inner platform 20, and the inner platform 20 is equipped with a third motor 24. The small gear 23 connected to the third motor 24 meshes with the large gear 22 on the top seat 3. Step 3: The third motor 24 can control the top seat 3 to rotate, so that the horizontal bar 14 can detect different positions. Compared with manual inspection of different positions one by one, this solution is more time-saving and labor-saving, and reduces the labor intensity of personnel.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
