Description

Technical Field

[0001] This invention relates to the field of floor flatness control technology, and in particular to a floor pouring flatness control device and method. Background Technology

[0002] In modern building construction, floor pouring is a crucial step in foundation engineering, and its flatness directly affects the quality of subsequent finishing and the overall aesthetics. Traditionally, after floor pouring, flatness testing relies primarily on manual measurement with a handheld level. This method is not only inefficient but also limited by the experience and skill level of the operators, making it difficult to guarantee the accuracy and consistency of the results. Furthermore, for any uneven areas detected, especially raised sections, the traditional practice is to use a hand grinder to smooth them down.

[0003] However, when grinding to control the flatness of the floor, there are many drawbacks to using a hand grinder: First, the large amount of dust generated by the grinding operation not only seriously pollutes the construction environment and poses a threat to the health of the operators, but also increases the burden of subsequent cleaning work; especially for the fine dust adhering to the ground, it is very difficult to clean; second, manual operation is inefficient and cannot meet the needs of large-scale construction, which prolongs the construction period and increases construction costs.

[0004] To address the above issues, we propose a device and method for controlling the flatness of concrete pouring. Summary of the Invention

[0014] A method for using a floor pouring flatness control device, comprising installing the floor pouring flatness control device in front of a mobile trolley, including the following steps:

[0015] Step 1: Move the trolley forward, which in turn moves the rectangular frame forward. When the distance sensors monitor the ground and keep the distance stable, the ground is flat. When the distance sensors monitor the ground and the distance decreases, there is a bump in that area.

[0016] When several distance sensors monitor the ground distance, if the distance monitored by the distance sensor increases, then there is a pit in that location;

[0017] Step 2: Move the trolley forward, which will move the rectangular frame forward. Several distance sensors will scan the entire protrusion or pit, and move the rectangular frame to the top of the protrusion or pit. Then, move the grinding disc to the top of the protrusion or pit through the XY cross slide.

[0018] Step 3: The motor drives the rotating shaft to rotate, which in turn drives the grinding disc to rotate. The U-shaped frame descends, and the grinding disc grinds the protrusions. The grinding disc rises relative to the rotating disc, and the bottom end of the protective ring rests on the ground.

[0019] For pits, the flathead drill bit extends out from the bottom of the grinding disc. The rotation of the turntable and the grinding disc causes the flathead drill bit to rotate, and at the same time, the flathead drill bit extends into the interior of the pit to deburr the pit at multiple points.

[0020] Step four: The vacuum cleaner is running. Airflow enters from the upper port between the circular block and the protective ring, and then enters the air guide shroud from the outer periphery of the bottom port. The airflow is close to the ground, and the vacuum cleaner sucks in the dust generated during the polishing process through several suction ports.

[0021] Step 5: After polishing, lift the cover using the U-shaped frame, detach the polishing disc from the ground, and keep the bottom end of the protective ring on the ground. The polishing disc descends relative to the turntable and is transmitted to the transmission mechanism via the rotating shaft. The transmission mechanism then drives the striking head to reciprocate and strike the polyester film. The two polyester films resonate and simultaneously generate waves towards the ground. These waves bounce up the dust adsorbed on the ground, and the vacuum cleaner sucks in the dust through several suction ports.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0023] 1. In this invention, the surface smoothness grinding operation is carried out by mechanical grinding, which ensures the health of the operators.

[0024] 2. In this invention, the tapping head repeatedly taps the polyester film to generate waves towards the ground. The waves bounce up the dust adsorbed on the ground, and the vacuum cleaner sucks in the dust through several suction ports, which can effectively remove the dust adsorbed on the ground.

[0025] 3. This invention can grind up uneven surfaces and deburr pits, making it easier for workers to repair later.

[0026] 4. This invention, by bringing the airflow close to the ground, allows dust to enter the suction port through the airflow guide channel, effectively removing dust adsorbed on the ground.

[0027] 5. In this invention, during polishing, the striking head can be made not to strike, thus reducing energy consumption. After polishing, the polishing disc is lifted off the ground, and the polishing disc pulls down the large bevel gear through the pull rod, so that the large bevel gear meshes with the first bevel gear, thereby causing the striking head to strike the polyester film.

[0056] The floor pouring flatness control device also includes a controller for data processing; the distance sensor 17 can feed the monitoring data back to the controller.

[0057] The controller is also used for the operation control of each unit.

[0058] A method for using a floor pouring flatness control device, comprising installing the floor pouring flatness control device in front of a mobile trolley, including the following steps:

[0059] Step 1: Move the trolley forward, which in turn moves the rectangular frame 1 forward. When the distance sensors 17 monitor the ground distance and keep it stable, the ground is flat. When the distance sensors 17 monitor the distance and the distance decreases, there is a bump in that area.

[0060] When several distance sensors 17 monitor the ground distance, if the distance monitored by the distance sensor 17 increases, then there is a pit at that location.

[0061] Step 2: The moving trolley moves forward, driving the rectangular frame 1 forward. Several distance sensors 17 scan the entire protrusion or pit. Based on the monitoring data of the several distance sensors 17 and the data of the moving trolley, the controller can determine the location of the protrusion or pit.

[0062] Move the rectangle 1 directly above the protrusion or pit, and use the XY cross slide 2 to move the grinding disc 9 directly above the protrusion or pit.

[0063] Step 3: Motor 6 drives the rotating shaft 7 to rotate, which in turn drives the grinding disc 9 to rotate via turntable 8. U-shaped frame 3 descends, and grinding disc 9 grinds the protrusion. Grinding disc 9 rises relative to turntable 8, and the first spring 905 remains compressed. Pull rod 1208 lifts the large bevel gear 1207, causing the large bevel gear 1207 to disengage from the first bevel gear 1205. Then, transmission mechanism 12 does not perform transmission, and the hammering head 11 does not operate.

[0064] The bottom end of the protective ring 13 is on the ground, and the protective ring 13 prevents dust from being thrown out, while the second spring 1304 is compressed;

[0065] For the pit, the electric push rod 906 drives the flat drill bit 10 to extend from the bottom of the grinding disc 9. Through the rotation of the turntable 8 and the grinding disc 9, the flat drill bit 10 rotates and extends into the pit to deburr the pit at multiple points. After deburring, the workers can directly see that the deburred area is the pit, and then the workers can manually repair it. The deburred pit can fully bond the pit with the concrete during repair, making the repaired concrete firmly bonded to the pit.

[0066] Step 4: The vacuum cleaner 16 is running. Airflow enters from the upper port between the circular block 5 and the protective ring 13, and then enters the air guide shroud 14 from the outer periphery of the bottom port. The airflow is close to the ground, and dust enters the suction port 15 through the guide groove 903 with the airflow. Then, it enters the annular pipe 1601 through the connecting pipe 1501, guide hole 805, connecting hole 806 and annular air duct 804. Then, the dust airflow enters the vacuum cleaner 16 from the suction pipe 1603. The vacuum cleaner 16 then sucks in the dust generated during the polishing process through several suction ports 15.

[0067] Step 5: After polishing, the cover 4 is lifted by the U-shaped frame 3, the polishing disc 9 is lifted off the ground, and the bottom end of the protective ring 13 remains on the ground. The first spring 905 pushes down the polishing disc 9, and the polishing disc 9 descends relative to the turntable 8. The polishing disc 9 then pulls down the large bevel gear 1207 through the pull rod 1208, so that the large bevel gear 1207 meshes with the first bevel gear 1205. The rotating shaft 7 rotates, and the large bevel gear 1207 rotates, which in turn transmits power to the first transmission shaft 1204, the second bevel gear 1206, the third bevel gear 1211 and the second transmission shaft 1209 in sequence. The T-shaped end of the T-shaped rod 1210 rotates in a circular trajectory and presses down the striking rod 1213 repeatedly. When the T-shaped rod 1210 disengages from the striking rod 1213, the torque of the torsion spring 1214 causes the striking rod 1213 and the striking head 11 to strike the polyester film 503.

[0068] The transmission is transmitted through the rotating shaft 7 to the transmission mechanism 12, which then drives the striking head 11 to reciprocate to strike the polyester film 503. The two polyester films 503 resonate and simultaneously generate waves towards the ground. The waves bounce up the dust adsorbed on the ground, and the vacuum cleaner 16 sucks in the dust through several suction ports 15, which can effectively remove the dust adsorbed on the ground.

[0069] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
