DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-5 A concrete surface leveling construction device includes a pressing plate 1, a box body 2 is fixed on the top of the pressing plate 1, a retractable handle 3 is rotatably connected to the top of the box body 2, a booster mechanism is arranged in the box body 2, the booster mechanism can generate reciprocating vibration in the box body 2 in the up and down directions, the pressing plate 1 is placed on the paved concrete surface, the box body 2 and the pressing plate 1 are pulled by the handle 3 to move on the concrete, and the up and down vibrations generated by the booster mechanism act on the concrete surface through the pressing plate 1, so that the concrete surface can be leveled.

[0026] Furthermore, the boosting mechanism includes two fixing seats 5 fixed in the box body 2, and the same main shaft 6 is rotatably connected between the two fixing seats 5. An eccentric wheel 7 is fixedly sleeved on the main shaft 6. A first motor 8 is fixed in the box body 2, and pulleys 9 are installed on the two output shafts of the first motor 8 and both ends of the main shaft 6. The two pulleys 9 in the same group are connected by a belt 10. When the two output shafts of the first motor 8 rotate, the main shaft 6 and the eccentric wheel 7 are driven to rotate through the transmission cooperation of the pulley 9 and the belt 10. When the eccentric wheel 7 rotates, it will generate vibrations in the up and down directions, thereby generating greater pressure on the concrete.

[0027] Furthermore, the boosting mechanism includes a counterweight 13, both sides of which are rotatably connected to connecting rods 12, the bottom end of the connecting rod 12 is rotatably connected to a rack 11, two guide plates 22 are fixed in the box body 2, the guide plates 22 are slidably connected to the rack 11, two fixed plates 14 are fixed in the box body 2, the fixed plates 14 are rotatably connected to a shaft 15, one end of the shaft 15 is fixedly sleeved with a half gear 16 meshing with the rack 11, the shaft 15 is connected to a driving assembly, the driving assembly drives the two shafts 15 to rotate in opposite directions, the shaft 15 synchronously drives the half gear 16 to rotate, so that the two racks 11 periodically move toward the middle at the same time, lift the counterweight 13, and then the counterweight 13 falls down under the action of gravity, thereby generating vibrations in the up and down directions, thereby generating greater pressure on the concrete.

[0028] Furthermore, the driving assembly includes a second motor 18 fixed on the fixing plate 14 , and the output shaft of the second motor 18 is connected to the shaft 15 , and the two shafts 15 are synchronously driven by the two second motors 18 to rotate in opposite directions.

[0029] Furthermore, the driving assembly includes a third motor 19 fixed in the housing 2, and the two output shafts of the third motor 19 are both equipped with first bevel gears 20, and the ends of the two shafts 15 are both equipped with second bevel gears 21, and the first bevel gears 20 are meshed and connected with the second bevel gears 21. The two output shafts of the third motor 19 respectively drive the two first bevel gears 20 to rotate, and the two first bevel gears 20 are respectively meshed to drive the two second bevel gears 21 to rotate, so that the two shafts 15 rotate in opposite directions.

[0030] Furthermore, a support column 17 for supporting the counterweight 13 is fixed to the inner wall of the bottom of the box body 2 and is located directly below the counterweight 13. A circular groove 23 is provided on the top of the support column 17, and a shock-absorbing pad 24 is fixed in the circular groove 23. When the counterweight 13 falls and hits the support column 17, the final position of the rack 11 can be limited by the support column 17, thereby preventing the rack 11 from meshing with the half gear 16 again during the outward movement, thereby protecting the rack 11 and the half gear 16 and reducing the wear between the two. The noise generated by the impact can be reduced by the shock-absorbing pad 24.

[0031] Furthermore, both ends of the pressing plate 1 are provided with an upwardly tilted arc portion 4. By providing the arc portion 4, it is possible to prevent the edge of the pressing plate 1 from causing an indentation on the concrete surface.

[0032] Working principle: Place the pressing plate 1 on the paved concrete surface, pull the box 2 and the pressing plate 1 on the concrete through the handle 3, and the up and down vibrations generated by the booster mechanism act on the concrete surface through the pressing plate 1, so that the concrete surface can be flattened;

[0033] The two working modes of the booster mechanism are as follows:

[0034] When the two output shafts of the first motor 8 rotate, the main shaft 6 and the eccentric wheel 7 are driven to rotate through the transmission cooperation of the pulley 9 and the belt 10. When the eccentric wheel 7 rotates, it will vibrate in the up and down directions, thereby exerting greater pressure on the concrete and flattening it;

[0035] The two second motors 18 synchronously drive the two shafts 15 to rotate in opposite directions, or the two output shafts of the third motor 19 respectively drive the two first bevel gears 20 to rotate, and the two first bevel gears 20 respectively mesh and drive the two second bevel gears 21 to rotate, so that the two shafts 15 rotate in opposite directions, and the shafts 15 synchronously drive the half gear 16 to rotate, so that the two racks 11 periodically move toward the middle at the same time, lift the counterweight 13, and then the counterweight 13 falls down under the action of gravity, thereby generating vibrations in the up and down directions, thereby generating greater pressure on the concrete to flatten it.
