Description

Technical Field

[0001] The utility model belongs to the technical field of house construction, and specifically relates to a ground leveling device. Background Art

[0002] Ground leveling is a basic project in house construction, and its quality directly affects the overall stability, service life of the house, and the quality of subsequent decoration. Using a ground leveling device can ensure that the ground flatness meets the standard requirements and avoid various problems caused by uneven ground, such as floor hollowing and cracking.

[0003] The prior art discloses an indoor floor leveling device for house construction (CN214220639U). A material pushing plate is installed at the bottom of one side of the vehicle body, and support frames are symmetrically installed on the other side of the vehicle body. Cylinders are installed above both support frames, and connecting rods fixedly connected to the upper part of the leveling shell are fixedly installed at the telescopic ends of both cylinders. The utility model has a simple structure and novel design. The movement of the vehicle body causes the concrete material to accumulate on one side of the material pushing plate. Through the sieve mesh, the accumulated concrete material can be evenly dispersed on the other side of the material pushing plate, improving the utilization rate of the concrete material. The motor drives the threaded rod to make the movable seat move on the sliding rod, so that the concrete material can be evenly dispersed, which is beneficial to the stability of the ground structure, avoids the occurrence of situations such as cracks and collapses on the ground in the later stage, and improves the service life of the concrete floor.

[0004] After retrieval, it is found that when changing the leveling position of this device, workers need to manually change its position, which will increase the labor burden of workers. At the same time, manually changing the position is likely to affect the already leveled ground and is not conducive to aesthetics; in addition, when using this device, workers need to cooperate to plane the soil cement, and this method does not save manpower, thus resulting in increased costs.

Specific implementation mode

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0029] A ground leveling device, as Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, includes

[0030] a support plate 10, the support plate 10 is slidably arranged on the ground; a planing assembly, the planing assembly is slidably arranged on one side of the support plate 10, the planing assembly includes a slider 14, a turbine 17, a worm 18, a positive and negative lead screw 19, a connecting rod 20 and a planing shovel 21, the planing shovel 21 is fixedly arranged below the connecting rod 20, the slider 14 is slidably arranged on the side surface of the support plate 10, the turbine 17 is fixedly arranged in the middle of the positive and negative lead screw 19, and both the positive and negative lead screw 19 and the worm 18 are rotatably arranged inside the slider 14; a transposition mechanism, the transposition mechanism is threadedly arranged inside the support plate 10, the transposition mechanism includes a thin sleeve 22, a fixed seat 25, a pulley 26, a thick sleeve 27, a support seat 28, a belt 31 and a transmission wheel 32, both the thin sleeve 22 and the thick sleeve 27 are elastically arranged inside the support plate 10, the fixed seat 25 is slidably arranged inside the thin sleeve 22, the support seat 28 is slidably arranged inside the thick sleeve 27, the pulley 26 is rotatably arranged below the fixed seat 25, the transmission wheel 32 is drivingly arranged inside the belt 31, and the belt 31 is rotatably arranged below the support seat 28.

[0031] The working principle is as follows. The movement of the entire device is driven by the transmission pulley 32 and the belt. First, the planing shovel 21 planes and loosens the ground. Then, the pulley 26 rolls over it. After that, it is leveled by the belt 31 and the transmission pulley 32. Finally, another pulley 26 compacts and finishes it. By setting up the planing assembly, the worm 18 drives the turbine 17 to rotate, so that the connecting rods 20 at both ends of the positive and negative lead screws 19 drive the planing shovels 21 to move inward or outward simultaneously, thereby gathering, planing or spreading the soil and cement, thus saving manpower and reducing costs at the same time. By setting up the transposition mechanism, the worker lifts the support base 28 by pulling, thereby lifting the transmission pulley 32 and the belt 31, and changing the moving direction of the belt 31 and the transmission pulley 32 by means of rotation. Similarly, by pulling the fixed seat 25 and rotating the fixed seat 25 to make the pulley 26 rotate, the moving direction of the pulley 26 is changed. In this way, the leveling direction of the device is changed without changing the position, which will not cause a labor burden on the worker and can also avoid affecting other leveled ground, thus making the ground more beautiful.

[0032] As Figure 1 and Figure 2 shown, the support plate 10 is a square. There are two through holes and a rotating hole inside the support plate 10. The two through holes are symmetrically arranged with the rotating hole as the midpoint. There are two pulley slots 11 and a flattening slot 12 on the top surface of the support plate 10. The two pulley slots 11 are located directly above the through holes, and the flattening slot 12 is located directly above the rotating hole. As Figure 1 and Figure 4 shown, a thin sleeve 22 is slidably connected inside the through hole. The thin sleeve 22 is an I-shaped cylinder. A buffer spring 23 is fixedly arranged between the thin sleeve 22 and the support plate 10. The thin sleeve 22 is elastically connected to the support plate 10 through the buffer spring 23. A thick sleeve 27 is slidably connected inside the rotating hole. The thick sleeve 27 is similar in shape to the thin sleeve 22. A resistance spring 30 is fixedly arranged between the thick sleeve 27 and the support plate 10. The thick sleeve 27 is elastically connected to the support plate 10 through the resistance spring 30. As Figure 2 and Figure 4 shown, the fixed seat 25 is composed of a thin cylinder and a U-shaped thin bracket. A short handle 24 is fixedly connected to the top surface of the thin cylinder. The short handle 24 is located above the thin sleeve 22. The thin cylinder slides inside the thin sleeve 22. A rotating shaft is fixedly arranged inside the U-shaped thin bracket. The fixed seat 25 is rotatably connected to the pulley 26 through the rotating shaft. The short handle 24 is clamped in the pulley slot 11. As Figure 2 、 Figure 4 and Figure 5As shown, the support base 28 is composed of a thick cylinder and a wide bracket. The thick cylinder slides inside the thick sleeve 27. The top surface of the thick cylinder is fixedly connected with a long handle 29. The long handle 29 is located above the thick sleeve 27. Two transmission wheels 32 are symmetrically arranged inside the wide bracket. Both transmission wheels 32 are rotatably connected to the wide bracket. Both transmission wheels 32 are connected to the same belt 31. A strip is fixedly connected to the outside of the wide bracket. A transmission motor 33 is fixedly arranged on the strip. A round hole is opened on one side of the wide bracket. The transmission motor 33 is arranged opposite to the round hole. The output end of the transmission motor 33 is connected to one end of one of the transmission wheels 32 through the round hole. The long handle 29 is clamped in the flattening slot 12.

[0033] The working principle is as follows. First, when the long handle 29 is horizontally clamped in the cross-shaped flattening slot 12, pull the long handle 29. The long handle 29 moves away from the flattening slot 12. At this time, the long handle 29 drives the thick cylinder to slide upward in the thick sleeve 27. At this time, the top surface of the wide bracket pushes the bottom of the thick sleeve 27 upward. The thick sleeve 27 squeezes the resistance spring 30. Then rotate the long handle 29. The thick cylinder rotates in the thick sleeve 27. When the long handle 29 reaches the vertical state, stop rotating. At this time, gently press and release the long handle 29. The long handle 29 is vertically clamped in the flattening slot 12. Similarly, when the short handle 24 is horizontally clamped in the cross-shaped pulley slot 11, pull the short handle 24. The short handle 24 drives the thin cylinder to slide upward in the thin sleeve 22. At this time, the thin sleeve 22 will move upward in the direction of the movement of the fixed seat 25 with the cooperation of the buffer spring 23. When the short handle 24 moves away from the pulley slot 11, rotate the short handle 24. The short handle 24 synchronously drives the fixed seat 25 and the pulley 26 to rotate. When the short handle 24 reaches the vertical state and is parallel to the state of the long handle 29, gently release and press the short handle 24 to make the short handle 24 vertically clamped in the pulley slot 11. In summary, by using the above method, the leveling movement direction of the device can be changed synchronously. With the cross-shaped shapes of the pulley slot 11 and the flattening slot 12, two mutually perpendicular leveling directions are provided for the device.

[0034] As Figure 1 、 Figure 2 and Figure 3 shown, a steering slideway 13 is fixedly connected to one side of the support plate 10. An L-shaped slideway is opened inside the steering slideway 13. The turning point of the L-shaped slideway is set as an arc surface. The slider 14 slides in the L-shaped slideway. A bracket 15 is fixedly connected to the side of the slider 14 away from the steering slideway 13. As Figure 3As shown in the figure, the bracket 15 is composed of a square box and two square plates. The two square plates are symmetrically arranged on the upper and lower sides of the square box. A through hole is provided in the square box, and a left - right screw rod 19 is rotatably connected in the through hole through a bearing. A worm 18 is rotatably arranged between the two square plates. A circular hole is provided on the top surface of the bracket 15. A micro - motor 16 is fixedly arranged directly above the circular hole through a tripod. The output end of the micro - motor 16 is connected to the top surface of the worm 18. A turbine 17 is in transmission connection with the worm 18. There are two connecting rods 20. Threaded holes and sliding holes in different directions are provided at the top ends of the two connecting rods 20. The sliding holes are located below the threaded holes. One sliding rod is fixedly connected to each of the outer sides of the square box. Both sliding rods are located below the left - right screw rod 19. The connecting rod 20 is threadedly connected to the left - right screw rod 19 through the threaded hole, and the connecting rod 20 slides on the sliding rod through the sliding hole.

[0035] The specific implementation method is as follows. Start the micro - motor 16 and the drive motor 33 respectively. The drive motor 33 drives the rotation of the drive wheel 32. The drive wheels 32 at both ends drive the belt 31 to move, so that the belt 31 moves on the ground, thereby pushing the pulleys 26 at both ends to move. The micro - motor 16 drives the worm 18 to rotate. The worm 18 meshes with and drives the turbine 17. The rotation of the turbine 17 drives the rotation of the left - right screw rod 19. Here, the micro - motor 16 is externally connected to a control switch, and the control switch controls the forward and reverse rotation of the micro - motor 16. The rotation of the left - right screw rod 19 will cause the connecting rods 20 connected at both ends to slide on the sliding rods. Here, the thread directions of the threaded holes inside the two connecting rods 20 at both ends are in opposite directions, so the left - right screw rod 19 can drive the two connecting rods 20 at both ends to move inwards or outwards synchronously. When the ground in one direction is leveled and the ground in the vertical direction needs to be leveled, with the pulleys 26 at both ends as the support, the worker lifts the long handle 29 to drive the movement direction of the drive wheel 32 and the belt 31, then lifts the short handle 24 to change the movement direction of the pulley 26, and then pushes the slider 14 to slide in the steering slideway 13, so that the planing assembly changes the planing direction, and the vertical change of the leveling position can be realized.
