Further, all be provided with operating handle 12 on every baffle that slides, when the electrical apparatus trouble, can artifical pulling the baffle that slides, the switching of manual operation control horizontal baffle.
A method for conveying reinforcing bars through a silo comprises the following steps.
The curved arc conveyer is located the circumference interval space of automatic conveying initiating terminal, and curved arc conveyer forehead reinforcing bar export aims at the terminal surface space center of arc apron, is responsible for running the hoop reinforcing bar circle and sending into the transfer orbit, promotes the hoop reinforcing bar and advances.
The curved arc conveyor is used for automatically conveying the annular reinforcing steel bars required by setting the arc length L of the slip form for binding, and if the circumference of the circle where the conveying track is located is T, the ratio L/T =1, 1/2, 1/3, 1/4 and … … of the arc length L of the slip form to the circumference T where the conveying track is located is set. And (4) automatically conveying the required annular reinforcing steel bars by adopting a curved arc conveyor for each set sliding mode arc length L.
When L = T, a curved arc conveyor is adopted to automatically convey the annular reinforcing steel bars needed by the whole circle of silo. According to efficiency of construction and silo size, can be with segmentation repeated setting many sets the utility model discloses a conveying track device to can use many conveyer simultaneous workings. That is, the whole silo is repeatedly provided with a plurality of groups of conveying track devices according to the specifications to form a complete circular conveying track.
And when L/T =1/2, 1/3, 1/4 and … …, each set of conveying track devices is arc-shaped.
Firstly, when the head end or the tail end of the annular reinforcing steel bar to be conveyed is not sleeved with the sleeve cap, the height of the sliding baffle is adjusted as follows.
The utility model discloses the preferred interval an that goes up along and arc apron 1 center through adjustment horizontal baffle 2 adapts to different diameter reinforcing bars, and the method is as follows:
if the diameter of the conventional circumferential steel bar is 16-25mm, a stainless steel pipe with the inner diameter of 28mm can be selected as the track, namely, the arc circumferential through groove of the arc upper track is selected as an arc groove with the diameter of 28 mm.
As shown in fig. 6, when the circumferential reinforcement with the diameter of 25mm is conveyed, the upper edge of the horizontal baffle 2 is adjusted to the position with the vertical distance a =14mm downwards from the center, and the minimum gap distance between the horizontal baffle 2 and the cover plate 1 is 28mm, so that the circumferential reinforcement with the diameter of 18-25mm can be accommodated.
As shown in fig. 5, when a steel bar with a diameter of 16mm is to be replaced, the horizontal baffle 2 can be moved upwards by about 4mm, a =10mm, and at this time, the gap vertical spacing is 24mm, the horizontal spacing is 28mm, and only one 16mm-20mm circumferential steel bar can be penetrated. In the present invention, the unit marked with respect to the size in the drawings is mm.
The utility model discloses a position adaptation of adjustment horizontal baffle 2's continuous conveying of different diameter reinforcing bars, it is very big to correspond the height, and a plurality of arc apron can be installed simultaneously to the great silo of reinforcing bar diameter change.
And secondly, when the head end or the tail end of the annular steel bar to be conveyed is coaxially sleeved with the sleeve cap, the height adjustment of the sliding baffle plate is only related to the outer diameter of the sleeve cap and is not limited by the diameter of the annular steel bar to be conveyed. The advantages of the cap arrangement are that: by adopting the sleeve cap, the penetrating groove space can be far larger than the diameter of the steel bar to be conveyed, and only the outer diameter side wall surface of the sleeve cap is in sliding contact with the arc circumferential through groove during conveying, so that the friction force can be reduced, and the pushing is facilitated. The limitation is that the curved conveyor must be reversed to allow room for the cap to open.
And 3, inserting the m circumferential reinforcing steel bars.
When binding joints with the set length of b are arranged between every two adjacent annular reinforcing steel bars, the total number of the annular reinforcing steel bars needed by the binding of the sliding mode arc length L is set to be n. In the present embodiment, b =1m is preferable.
When two adjacent circumferential reinforcing steel bars are only in end-to-end contact without overlapping, the total number of the circumferential reinforcing steel bars corresponding to the arc length L of the slip form is set to be m, and m is less than n.
Conveying the first ring to the steel bar: starting the curved arc conveyor 6, sending the one end of the first hoop reinforcing steel bar into between the guide wheel and the compression roller of the curved arc conveyor and slightly pushing forward, the first hoop reinforcing steel bar advances under the drive of the curved arc conveyor, the first hoop reinforcing steel bar enters into the hoop reinforcing steel bar penetrating slot formed in the middle of the arc cover plate 1 and the horizontal baffle plate 2, and the hoop reinforcing steel bar penetrating slot advances under the limitation of the horizontal baffle plate 2 and the arc cover plate 1 until the first hoop reinforcing steel bar penetrates the slot to leave the curved arc conveyor.
When the sleeve cap is not needed, the conveying method of the first annular reinforcing steel bar is directly repeated, and the m annular reinforcing steel bars sequentially pass through the arc bending conveyor to run and be conveyed into the annular reinforcing steel bar inserting grooves in the step 2.
When the sleeve cap is needed, the sleeve cap is coaxially sleeved at the tail end of the first annular reinforcing steel bar or the head end of the second annular reinforcing steel bar, and then the arc bending conveyor is started and rotates for a distance to enable the sleeve cap to be opened. And then, repeating the conveying method and the cap sleeving action of the first annular reinforcing steel bar, and conveying the m annular reinforcing steel bars to the annular reinforcing steel bar inserting grooves in the step 2 after the m annular reinforcing steel bars sequentially pass through the arc bending conveyor to run circles.
Under the automatic conveying of curved arc conveyer, the preceding hoop reinforcing bar of mode promotion (because the hoop reinforcing bar interlude groove is not enough to send into two hoop reinforcing bars simultaneously side by side or the two hoop reinforcing bars that the cover was equipped with the cap) is supported tightly with the head and the tail to the back hoop reinforcing bar in the m root ring reinforcing bar, moves forward along the hoop reinforcing bar interlude groove and alternates until the first hoop reinforcing bar that is located foremost reachs the settlement target location.
Because the joint of the binding steel bars is provided with the overlapping joint, the total length required by a circle of steel bars is larger than the circumference of the silo, when the first annular steel bar penetrates out of the annular steel bar inserting groove, because the arc cover plate and the horizontal baffle plate at the tail end are lower in position and slightly downward and inward in direction, the first annular steel bar basically keeps an arc shape and penetrates in from the lower part of the inner side of the annular steel bar inserting groove due to self gravity deformation. The appointed position sensor 5 detects that the first ring is in place to the steel bar and sends a signal, and at the moment, the transmission action of the arc bending conveyor is stopped.
The preferred method is as follows: the first section of guide rail key is started to be opened, the air compressor drives the control valve to exchange directions, the air cylinder is pulled back or the linear motor works to drive the first root ring to withdraw a stroke towards the horizontal baffle 2 below the reinforcing steel bar, and the notch below the arc-shaped cover plate 1 is opened. The first hoop reinforcing steel bar is blocked by the vertical stop column 4 arranged at the end part of the track and the middle gap, and cannot be withdrawn along with the horizontal baffle 2, and can only fall into the opening below the arc-shaped cover plate 1 so as to fall onto the sliding form platform or the ground.
