Description

Technical Field

[0001] The invention belongs to the technical field of building construction equipment, and specifically refers to a high-precision ground leveling device. Background Art

[0002] In building decoration projects, leveling refers to flattening the uneven surface of the ground or wall, and adjusting and controlling the slope of the ground or wall. In modern buildings, leveling is mostly to apply a layer of concrete on the surface of the ground or wall to make the surface of the ground or wall achieve the desired effect.

[0003] For some special indoor places such as hospitals, the ground needs to have a certain degree of flatness. During the interior decoration process, workers use the method of pulling lines to achieve manual leveling when laying mortar. The flatness of the ground depends more on the workers' professional experience and professionalism. In order to achieve better construction results, the surface is often repeatedly plastered to control the height difference and flatness of the floor. The construction is difficult and it is difficult to achieve high-precision leveling.

[0004] Among the existing leveling devices, the steel wire leveling device requires manual wiring, which has disadvantages such as manual wiring errors, uneven bracket spacing, difficult to control firmness, and insufficient steel wire tension, which affect the leveling reference accuracy; the structural parts of the mechanical balance beam leveling device are too large, which makes it difficult to store and transport, and the adhesion phenomenon is serious and difficult to clean. Therefore, an automatic and accurate ground leveling device is needed. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a high-precision ground leveling device, which drives the track wheel to rotate through the main motor, and the main motor gear of the main motor is a small section of tooth design, which drives the track wheel to move forward intermittently, providing sufficient leveling time for the leveling component. At the same time, the main motor drives the driving face gears on both sides to rotate, and the driving face gears on both sides are respectively connected to the main transmission rod and the auxiliary transmission rod, so that the two rotate in opposite directions. When the screw face gears at both ends of the screw shaft are respectively meshed and connected with the driving face gears on different sides, the rotation direction of the screw shaft is also different. The screw shaft drives the screw sleeve to rotate, and the balance frame driving member moves with the rotation of the screw sleeve. When the balance frame driving member moves to one end of the screw sleeve, the cross column of the balance frame driving member pushes the screw shaft to move, so that this section of the screw face gear is meshed and connected with the driving face gear, thereby changing the rotation direction of the screw sleeve In the direction, the balancing frame driving part drives the balancing frame to make reciprocating motion on the bracket guide rail, realizing the technical effect that the balancing frame driving part drives the balancing frame to make reciprocating motion on the bracket guide rail; during the movement of the balancing frame, the paving auger will push the excess concrete forward to form a relatively flat concrete layer at its bottom, the paving auger will be higher than the compacting roller, and as the frame moves forward, the rotating compacting roller will compact the concrete in front, and under the action of the friction between the steering slider and the bracket guide rail, the steering slider will deviate in the opposite direction in the steering slider groove following the moving direction of the balancing frame, so that the compacting roller will tilt in the corresponding direction when following the movement of the balancing frame, and the inclined compacting roller will squeeze the excess concrete to the paving auger, and then the surface will be smoothed by the smoothing wheel. When smoothing, the excess concrete will be brought to the front due to the rotation of the smoothing wheel, and squeezed to the front by the tail of the inclined compacting roller, and then cleaned by the paving auger, realizing the technical effect of high-precision ground leveling.

[0018] Preferably, when the balance frame slides on the bracket guide rail, the friction between the steering slider and the bracket guide rail makes the steering slider slide only pushed by the two side walls of the steering slider groove. The different left and right moving directions of the balance frame make the steering slider have different positions in the steering slider groove, thereby changing the inclination direction of the toggle rod, that is, the inclination direction of the compaction roller when rotating changes with the moving direction of the balance frame, so that the compaction roller has a larger contact area in the horizontal direction, thereby improving the compaction effect of the compaction roller on the concrete and improving the accuracy of ground leveling.

[0021] The beneficial effects achieved by the present invention using the above structure are as follows:

[0022] 1. The main motor gear has only one arc-shaped tooth. When the main motor gear rotates, it will drive the wheel shaft gear to rotate intermittently, that is, when the main motor is working, it drives the track wheel to move forward intermittently, providing sufficient leveling time for the leveling component. At the same time, the main motor drive wheel of the main motor drives the main drive rod to rotate.

[0023] 2. The main transmission rod drives the right driving face gear to rotate, and the auxiliary transmission rod drives the left driving face gear to rotate, so that the rotation directions of the driving face gears on both sides are opposite, and then the screw face gear of the screw shaft rotates in different directions when meshing with different driving face gears. When the screw shaft rotates, it will drive the screw sleeve to rotate, and the balance frame drive will translate with the rotation of the screw sleeve. When the balance frame drive moves to the two ends of the screw sleeve, the cross column of the balance frame drive will pass through the hole of the screw support and push the screw face gear on this side to move, so that it meshes with the driving face gear, thereby changing the rotation direction of the screw shaft, and the balance frame drive moves in the opposite direction, achieving the technical effect of the balance frame drive driving the leveling assembly to perform reciprocating motion. At the same time, the tooth protection spring plays a buffering role in the meshing process of the driving face gear and the screw face gear to prevent the teeth from breaking due to mutual collision.

[0024] 3. When the balance frame is not level, the balance ball in the spirit level will shift to a lower position due to its own gravity. The elastic force of the pressure springs on both sides will change and be fed back to the control box. The control box will control the extension of the hydraulic column at the lower position to restore the balance frame to a level position.

[0025] 4. When the balance frame slides on the bracket guide rail, the friction between the steering slider and the bracket guide rail makes the steering slider slide only pushed by the two side walls of the steering slider groove. The different left and right moving directions of the balance frame make the steering slider in the steering slider groove have different positions, thereby changing the inclination direction of the toggle lever, that is, the inclination direction of the compacting roller when rotating changes with the moving direction of the balance frame, so that the compacting roller has a larger contact surface in the horizontal direction, thereby improving the compacting effect of the compacting roller on the concrete and improving the accuracy of ground leveling.

[0026] 5. When the paving auger rotates, it will push the excess concrete forward to form a relatively flat concrete layer. The paving auger will be higher than the compacting roller. When the frame moves forward, the rotating compacting roller will compact the concrete in front. At the same time, when the inclined compacting roller moves horizontally with the balance frame, it will squeeze the excess concrete to the paving auger to prevent concrete accumulation. The surface will then be smoothed by the smoothing wheel. When smoothing, the excess concrete will be brought to the front due to the rotation of the smoothing wheel and squeezed to the front by the tail of the inclined compacting roller, and then cleaned by the paving auger.

[0052] The leveling and compacting assembly 5 includes a leveling wheel 51, a compacting wheel driving rod 52, a steering lever 53 and a compacting roller 54. The leveling wheel 51 is arranged at the bottom of the protective box 32. A leveling transmission wheel 511 is arranged on the top of the right leveling wheel 51, and a leveling transmission wheel group 512 is arranged on the top of the left leveling wheel 51. The leveling transmission wheel 511 is connected to the leveling transmission wheel group 512 through a transmission belt, and the leveling transmission wheel group 512 is connected to the auxiliary motor transmission wheel 412 through a transmission belt.

[0053] The compacting wheel driving rod 52 includes a driving rod transmission wheel 521 and a driving rod bevel gear 522, and the steering toggle rod 53 includes a steering slider 531, a telescopic rod 532, a toggle rod 533 and a compacting wheel driving shaft sleeve 534. The compacting wheel driving rod 52 is arranged in the compacting wheel driving shaft sleeve 534, and a toggle rod positioning column 323 is provided in the protective box 32. The center of the toggle rod 533 rotates on the toggle rod positioning column 323. A steering slider groove 326 is provided on the rear side of the protective box 32. The steering slider 531 slides in the steering slider groove 326. The steering slider 531 is fitted with the outer wall of the bracket guide rail 13. One end of the telescopic rod 532 is hinged on the steering slider 531, and the other end of the telescopic rod 532 is fixed on the toggle rod 533.

[0054] Among them, when the balance frame 3 slides on the bracket guide rail 13, the friction between the steering slider 531 and the bracket guide rail 13 makes the steering slider 531 slide only by the two side walls of the steering slider groove 326. The different left and right moving directions of the balance frame 3 make the position of the steering slider 531 in the steering slider groove 326 different, thereby changing the inclination direction of the toggle rod 533, that is, the inclination direction of the compacting roller 54 when rotating changes with the moving direction of the balance frame 3, so that the compacting roller 54 has a larger contact surface in the horizontal direction, thereby improving the compaction effect of the compacting roller 54 on the concrete and improving the accuracy of ground leveling.

[0055] The compaction roller 54 is arranged between the smoothing wheel 51 and the paving auger 42. Support rods 541 and compaction transmission wheels 542 are arranged at both ends of the compaction roller 54. The top of the support rod 541 is arranged on the toggle rod 533. Compaction roller changing grooves 322 are arranged on both sides of the protection box 32. The support rod 541 slides in the compaction roller changing groove 322. The compaction transmission wheel 542 is connected to the drive rod transmission wheel 521 through a transmission belt.

[0056] Among them, when the spreading auger 42 rotates, it will push the excess concrete forward to form a relatively flat concrete layer. The spreading auger 42 will be higher than the compacting roller 54. When the frame 1 moves forward, the rotating compacting roller 54 will compact the concrete in front. At the same time, when the inclined compacting roller 54 moves horizontally with the balance frame 3, it will squeeze the excess concrete to the spreading auger 42 to prevent concrete accumulation. After that, the surface will be smoothed by the smoothing wheel 51. When smoothing, the excess concrete will be brought to the front side due to the rotation of the smoothing wheel 51, and will be squeezed to the front side by the tail of the inclined compacting roller 54, and then cleaned by the spreading auger 42.

[0057] When in use, the device is placed on a leveling reference surface, the main motor 21 and the auxiliary motor 41 are started, the main motor gear 211 of the main motor 21 drives the axle gear 122 of the axle 121 to rotate intermittently, and then the axle 121 drives the track wheel 12 to move forward intermittently, the main motor transmission wheel 212 drives the main rod transmission wheel 222 of the main transmission rod 22, and then the main transmission rod 22 rotates, the main rod transmission gear 223 on the main transmission rod 22 drives the auxiliary rod transmission gear 232 of the auxiliary transmission rod 23 to rotate, and then the auxiliary transmission rod 23 rotates, the main rod gear 221 of the main transmission rod 22 drives the right driving face gear 24 to rotate, and the auxiliary rod gear 231 of the auxiliary transmission rod 23 drives the left driving face gear 24 to rotate in the opposite direction, when the right driving face gear 24 and the screw shaft 25 are in contact, the main rod transmission gear 221 of the main transmission rod 22 drives the right driving face gear 24 to rotate, and the auxiliary rod gear 231 of the auxiliary transmission rod 23 drives the left driving face gear 24 to rotate in the opposite direction. When the right-side screw face gear 251 is meshed and connected, it drives the screw shaft 25 to rotate, and the screw sleeve 26 rotates with the screw shaft 25, thereby driving the balance frame driving component 27 to move to the left. When the balance frame driving component 27 moves to the leftmost side of the screw sleeve 26, the cross column 272 will push the screw face gear 251 of the screw shaft 25 to move to the left, thereby making the screw face gear 251 on the left side of the screw shaft 25 mesh with the left driving face gear 24, and making the right-side screw face gear 251 disengage from the driving face gear 24, and then the screw shaft 25 rotates in the opposite direction, and the screw sleeve 26 rotates in the opposite direction and drives the balance frame driving component 27 to move right. During the movement of the balance frame driving component 27, the connecting column 273 of the balance frame driving component 27 drives the sliding plate 31 of the balance frame 3 to move on the bracket guide rail 13.

[0058] During the movement of the balancing frame 3, when the level 34 senses that the balancing frame 3 is in a non-horizontal state, the balancing ball 341 in the level 34 deviates to a lower position due to its own gravity, and then the elastic force of the pressure springs 342 on both sides of the balancing ball 341 changes, and the elastic force of the pressure springs 342 changes and is fed back to the control box 14, and the control box 14 controls the hydraulic column 313 at the lower position to extend, and the roller 314 at the bottom of the hydraulic column 313 rolls in the bracket guide rail 13, and the balancing frame 3 is restored to the horizontal state; at the same time, the steering slider 5 The friction between 31 and the bracket guide rail 13 makes the sliding of the steering slider 531 only pushed by the two side walls of the steering slider groove 326. The different left and right moving directions of the balance frame 3 make the position of the steering slider 531 in the steering slider groove 326 different, thereby driving the tilting direction of the telescopic rod 532 to change, and the telescopic rod 532 drives the tilting direction of the toggle rod 533 to change. The two ends of the toggle rod 533 are connected to the support rods 541 on both sides of the compacting roller 54. When the toggle rod 533 rotates, it drives the compacting roller 54 to rotate.

[0059] When the auxiliary motor 41 is started, the auxiliary motor gear 411 drives the spur gear 442 of the transmission member 2 44 to rotate, and the bevel gear 441 of the transmission member 2 44 drives the bevel gear 432 of the transmission member 1 43 to rotate, and then the transmission wheel 431 of the transmission member 1 43 drives the auger transmission wheel 421 of the paving auger 42 to rotate, and the paving auger 42 pushes the excess concrete on the front side to the front; the auxiliary motor bevel gear 413 of the auxiliary motor 41 drives the drive rod bevel gear 522 of the compacting wheel drive rod 52 to rotate, and the compacting wheel drive rod 52 rotates on the compacting wheel of the steering toggle rod 53. In the driving sleeve 534, the driving rod transmission wheels 521 at both ends of the compacting wheel driving rod 52 drive the compacting transmission wheel 542 of the compacting roller 54 to rotate, and then the compacting roller 54 compacts the surface cleaned by the paving auger 42; the auxiliary motor transmission wheel 412 of the auxiliary motor 41 drives the smoothing transmission wheel group 512 on the left smoothing wheel 51 to rotate, and the smoothing transmission wheel group 512 drives the smoothing transmission wheel 511 of the right smoothing wheel 51 to rotate, and then the smoothing wheel 51 smoothes the compacted ground. The above-mentioned working arrangement realizes high-precision ground leveling of the device.
