Detailed Description
The technical solution of the present invention will be described in further detail with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.
Referring to fig. 1 to 3, an embodiment of the present invention provides an automatic control device for flatness of a cast-in-situ concrete slab.
As shown in fig. 1, the automatic control device for the flatness of the cast-in-situ concrete slab comprises a base 1 and a bracket 2, wherein the bracket 2 is fixedly arranged on the base 1, one end part of the bracket 2 is connected with a cross rod 3, and the cross rod 3 is connected with a pinch roller mechanism; the pinch roller mechanism can do horizontal reciprocating motion along the cross rod 3, and the pinch roller mechanism can do reciprocating motion along the vertical direction.
As shown in fig. 2, the pinch roller mechanism comprises a pinch roller 8 and a lifting device, wherein the lifting device comprises a gear set 9 and a lifting rod 10; a servo motor 11 for driving the gear set 9 to rotate is fixedly arranged on the sliding block 5, and a rack 12 meshed with the gear set 9 is arranged on the lifting rod 10; the pinch roller 8 is rotatably connected with the end part of the lifting rod 10 through a bearing.
Because the height of the pinch roller 8 in the vertical direction is required to be kept unchanged all the time in the process of rolling the concrete slab surface by the reciprocating movement of the pinch roller 8 in the horizontal direction; therefore, a transmission mode in which the gear set 9 is meshed with the rack 12 and the lifting rod 10 does not slide in the vertical direction when the pressing wheel 8 moves in the horizontal direction after the lifting rod 10 moves up and down in the vertical direction is required.
It should be noted that this set of movements is performed separately from the telescopic movements of the piston rod of the cylinder 7, which will be mentioned below, without interfering with each other, avoiding the occurrence of uneven pressure exerted by the pinch roller 8 on each area of the concrete slab, possibly resulting from simultaneous movements of the two sets, thus causing undulation of the concrete slab, and further ensuring the flatness of the concrete slab.
As shown in fig. 3, a sliding rail 4 is arranged on the cross bar 3, a sliding block 5 is connected to the sliding rail 4 in a sliding manner, and the pinch roller mechanism is fixedly connected with the sliding block 5; the number of the cross bars 3 is two, the number of the sliding blocks 5 is matched with the number of the cross bars 3, a movable rod 6 is fixedly connected between the sliding blocks 5, an air cylinder 7 used for driving the movable rod 6 to reciprocate along the horizontal direction is arranged on one side of the support 2, and the end part of a piston rod of the air cylinder 7 is fixedly connected with the middle part of the movable rod 6.
The telescopic movement of the piston rod of the air cylinder 7 drives the movable rod 6 to reciprocate along the horizontal direction, and the sliding block 5 drives the pinch roller mechanism to reciprocate along the horizontal direction, so that the pinch roller 8 with the contact surface of the concrete slab surface lowered to the preset elevation can roll the concrete slab surface, the concrete higher than the elevation is extruded out from the gap between the brackets 2 in the rolling process, and the elevation of the concrete slab surface after rolling meets the preset requirement.

After the required elevation is determined, the infrared sensing device 13 is fastened and installed at the bulge 14 corresponding to the scale mark by utilizing the double-lug screw 15, so that the elevation of the contact surface of the pinch roller 8 and the concrete slab surface is always consistent when the pinch roller descends, and when a constructor transfers the concrete pouring device to another place with concrete pouring, the elevation does not need to be recalibrated like the traditional mode, and the working efficiency of concrete pouring work is improved.
The bracket 2 is provided with a control mechanism 16, a signal input end of the control mechanism 16 is connected with the infrared sensing device 13, and a signal output end of the control mechanism 16 is respectively connected with the air cylinder 7 and the servo motor 11.

The working principle of the invention is as follows: after the invention is placed at the position to be poured with concrete, firstly, the infrared induction device 13 is fastened at the position corresponding to the scale mark of the bulge 14 according to the required elevation, and then the concrete is poured at the position to be poured with concrete until the concrete slab surface slightly exceeds the required elevation distance;
then, the invention is started, the gear group 9 is matched with the lifting rod 10 to enable the pinch roller 8 to descend until the infrared sensing device 13 detects the pinch roller 8, namely, the pinch roller 8 reaches the height set by elevation, after receiving feedback information of the infrared sensing device 13, the control mechanism 16 cuts off the power supply of the servo motor 11 and simultaneously turns on the power supply of the air cylinder 7, the piston rod of the air cylinder 7 pushes the moving rod 6, the moving rod 6 drives the sliding block 5 to horizontally reciprocate along the sliding rail 4, and the pinch roller mechanism fixedly connected with the sliding block 5 simultaneously reciprocates along the horizontal direction, so that the pinch roller 8 can roll the concrete slab surface;
in the rolling process, the superfluous concrete with the concrete slab surface higher than the elevation is slowly extruded to two sides by the pinch roller 8, after the rolling is finished, an instruction is sent to the control mechanism 16, the control mechanism 16 controls the lifting rod 10 to lift, the pinch roller 8 is gradually lifted and far away from the concrete slab surface, then constructors move away the concrete slab, and the superfluous concrete remained around the concrete slab surface is simply cleaned, so that the ending work can be finished.
