then, the third air cylinder 215 pushes the steel bar on the first support rail 216 to move down to the upper portion of the second support rail 2163 along the descending rail 2161, and the steel bar is supported on the upper portion of the second support rail 2163 by the lifting block 2222, such that the height of the steel bar at the prefabricated plate 2353 is between the lower positioning portion 22331 and the upper positioning portion 22332 and the steel bar is on the upper portion of the side positioning portion 2235, and then, the servo motor in the driving rotary member 224 is started, such that the driving rotary member 224 rotates and drives the swing rod 2232 to move along the first positioning groove 2231 through the arc-shaped protrusion 2241, and the swing rod 2232 moves through the first positioning member 2233, such that the first positioning member 2233 pushes the steel bar between the lower positioning portion 22331 and the upper positioning portion 22332, as shown in fig. 6-7, thereby achieving the effects of positioning the steel bar left and right and preventing the angle deviation between the steel bar and the container;
when the driving rotating piece 224 rotates, the driving rotating piece 224 drives the side positioning portions 2235 to compress the second pre-tightening springs 2236 to move along the second limiting grooves 2234 through the arc-shaped protruding portions 2241, so that the front and rear groups of side positioning portions 2235 position the steel bars, and the steel bars are kept in the middle positions of the containers right below the corresponding containers, thereby achieving the effect of positioning the steel bars front and rear;
it should be added that, in the present invention, the servo motor for controlling the rotation of the driving rotary member 224 may adopt a rotation angle of 45 degrees each time, four sets of arc-shaped protrusions 2241 on the outer side of the driving rotary member 224 are arranged around the driving rotary member 224, so that the driving rotary member 224 has two switching states of jacking up the swing link 2232 and disengaging from the swing link 2232 through the arc-shaped protrusion 2241, a pushing device for driving the sliding block 221 to move along the first guide slot 2111 is arranged in the main transfer rail 211, and a pushing speed of the pushing device is equal to a moving speed of the conveyor belt 103, wherein the pushing device may be replaced by a gear transmission, which is not shown in the figure;
after the steel bars are positioned in all directions above the container, the pushing device in the main transfer rail 211 drives the lifting shaft 222 to move through the sliding block 221, the lifting shaft 222 pushes the lifting block 2222 to move along the second support rail 2163 to be separated from the second support rail 2163 and fall into the container filled with concrete which is pushed by the pushing plate 1031 above the conveyor belt 103, and in the process, the steel bars in the container filled with concrete vibrate along with the concrete and gradually sink from the top of the container to the middle of the container, as shown in fig. 9, the state where the position-restricting sleeve 2221 is separated from the slider 221 at a is gradually changed to the state where the position-restricting sleeve 2221 is in contact with the slider 221 at b, the height of the moving table 223 is limited by the limiting sleeve 2221 acting on the sliding block 221, so that the lifting shaft 222 is prevented from falling into the bottom of the container due to the fact that the lifting shaft is lowered too much along the sliding block 221, and the effect of preventing the reinforcing steel bars from sinking into the bottom of the container in the container oscillation process is achieved;
as shown in fig. 3 and 8-9, after the steel bar is positioned and sunk into the middle of the container to be horizontally placed, the movable table 223 starts to work to disengage from the steel bar, as shown in the process b-c in fig. 9, the driving rotary member 224 is activated again and rotated 45 degrees, so that the arc-shaped protrusion 2241 no longer abuts against one side of the swing rod 2232 and the side positioning portion 2235, the swing rod 2232 and the side positioning portion 2235 are reset under the action of the first pre-tightening spring 22333 and the second pre-tightening spring 2236, respectively, at this time, the side positioning portion 2235 and the first pre-tightening spring 22333 disengage from the steel bar, and at the same time, the push plate pushes the container to move and disengage from the oscillation zone directly above the partition 105, the pushing device drives the lifting shaft 222 to move through the sliding block 1031221, the lifting shaft 222 drives the lifting block 2222 to ascend along the lifting rail 2162 to the side of the first cylinder 213 through the inclined portion 22221, at this time, the movable table 223 disengages from the plane of the upper end of the container, and the first cylinder 213 pushes the positioning assembly 22 into the secondary transfer rail 212 through the main transfer rail 211, thereby achieving the effect that the positioning assembly 22 can be automatically positioned and cycled with the movement of the transport unit.
Example two
As shown in fig. 3, in which the same or corresponding components as in the first embodiment are denoted by the same reference numerals as in the first embodiment, only the points of difference from the first embodiment will be described below for the sake of convenience. The second embodiment is different from the first embodiment in that:
the charging unit 3 includes:
a concrete pre-storage tank 301;
the lower part of the concrete pre-storage tank 301 is connected to the upper part of the transfer pipe 302 through a discharge port 3012;
an extrusion mechanism 303 is movably inserted in the transfer pipe 302;
preferably, the inner bottom of the concrete pre-storage tank 301 is provided with an inclined bottom 3011 for facilitating the concrete to slide into the transfer pipe 302.
It should be noted that, in the present invention, when the extruding mechanism 303 is driven along the right below the transportation unit 1, the extruding mechanism 303 moves along the transfer pipe 302, so as to directly convey the concrete in the concrete pre-storage tank 301, which enters the transfer pipe 302 through the discharge port 3012, into the container and fill the container, and then perform the subsequent reinforcing steel bar positioning operation, so that the present invention has high working efficiency, and avoids the existing method that half of the concrete is loaded into the container first, the reinforcing steel bar is placed, and the other half of the concrete is poured into the container, which results in low working efficiency and complex process.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
