DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 7 The present invention provides a centrifugal material distribution device for a cement pole production line.

[0037] like Figure 1 and Figure 2 As shown, in one embodiment, a centrifugal material distribution device for a cement pole production line includes a base plate 100, a rifle pole 200, a placement wheel 300, a driving motor 400, a transmission wheel 500 and a driven member 600.

[0038] The rifle bar 200 is rotatably mounted on the base plate 100 .

[0039] The placement wheel 300 is installed on the rifle pole 200 in a horizontally displaceable manner, and is used to support and drive the steel mold of the cement pole to rotate.

[0040] Specifically, the axial section of the placement wheel 300 is in the shape of an I, and the raised reinforcing ribs of the steel mold fall on the middle surface of the placement wheel 300 to achieve the function of the placement wheel 300 pulling the steel mold for synchronous displacement.

[0041] The driving motor 400 is mounted on the base plate 100 .

[0042] The transmission wheel 500 is mounted on the rotating shaft of the driving motor 400 .

[0043] One end of the driven member 600 is rotatably mounted on a surface of the transmission wheel 500 that is offset from the axis of the transmission wheel 500 , and the other end is mounted on the placement wheel 300 .

[0044] During the rotation of the driving motor 400 , the transmission wheel 500 rotates synchronously and drives the placement wheel 300 to move back and forth along the rifle rod 200 through the follower 600 .

[0045] Specifically, in the process of centrifugal distribution production of cement poles, the steel mold poured with concrete is placed on the placement wheel 300, and the drive motor 400 is started. The drive motor 400 rotates to drive the transmission wheel 500 to rotate synchronously. The transmission wheel 500 drives the placement wheel 300 to move back and forth along the axial direction of the rifle pole 200 through the driven member 600. The placement wheel 300 drives the steel mold to swing synchronously, thereby promoting a more even distribution of concrete in the steel mold.

[0046] like Figure 3 and Figure 4As shown, in one embodiment, the follower 600 includes a follower rod group 610, a follower plate 620 and a follower claw 630. The follower rod group 610 is installed on the surface of the transmission wheel 500 that deviates from the axis. The follower plate 620 is rotatably installed at one end of the follower rod group 610 away from the transmission wheel 500. One end of the follower claw 630 is rotatably installed on the follower plate 620, and the other end thereof is installed on the placement wheel 300.

[0047] In this embodiment, the driven rod group 610 includes a main driven rod 612 and a secondary driven rod 614. The main driven rod 612 is rotatably mounted on the surface of the transmission wheel 500 that deviates from the axis. One end of the secondary driven rod 614 is rotatably connected to the main driven rod 612, and the other end is rotatably mounted on the driven plate 620.

[0048] In this embodiment, the surface of the rifle lever 200 corresponding to the placement wheel 300 has a driving surface 201 , and the placement wheel 300 is rotatably mounted on the driving surface 201 .

[0049] In the process of the placement wheel 300 moving back and forth along the rifle rod 200 , the driving surface 201 on the rifle rod 200 drives the placement wheel 300 to rotate.

[0050] In this embodiment, a driving groove is provided on the driving surface 201 , and a driving thread is provided on the inner wall of the placement wheel 300 , and the driving thread matches the driving groove.

[0051] In this embodiment, the placement wheel 300 has an annular groove 301 , which is coaxially arranged with the placement wheel 300 . There are at least two groups of annular grooves 301 , which are distributed on both side surfaces of the placement wheel 300 .

[0052] Preferably, the two groups of annular grooves 301 are symmetrically arranged on the two side surfaces of the placement wheel 300, or the two groups of annular grooves 301 are distributed on the two side surfaces of the placement wheel 300 in a concentric circle manner.

[0053] In this embodiment, one end of the driven claw 630 away from the driven plate 620 has a sliding column 632 . The sliding column 632 is arranged corresponding to the annular sliding groove 301 , and the outer diameter of the sliding column 632 matches the width of the annular sliding groove 301 .

[0054] Specifically, when the placement wheel 300 is driven to move back and forth along the rifle rod 200, the driving motor 400 drives the master-slave rod 612 to swing back and forth through the transmission wheel 500, and the master-slave rod 612 drives the driven plate 620 to swing in the horizontal direction through the secondary driven rod 614, and the driven plate 620 drives the placement wheel 300 to move back and forth synchronously through the driven claw 630. During this process, the placement wheel 300 is displaced along the rifle rod 200, and the placement wheel 300 is driven by the inner wall of the driving groove to move in a spiral path along the axial direction of the rifle rod 200, thereby prompting the placement wheel 300 to displace and rotate on the rifle rod 200, thereby realizing centrifugal distribution of the steel mold poured with concrete and axial swing to improve the uniformity of concrete distribution.

[0055] In this embodiment, the centrifugal material distribution device for the cement pole production line further includes an adjustable support plate 700 , which is displaceable along the width direction of the bottom plate 100 and symmetrically installed on the bottom plate 100 .

[0056] Specifically, a mounting plate is installed on the adjustable support plate 700, a motor seat is installed on the outer wall of the mounting plate, the drive motor 400 is installed on the motor seat, a support seat is installed on the mounting plate, and the rifle rod 200 penetrates and is fixedly installed on the support seat.

[0057] Preferably, the adjustable support plate 700 is arranged in a "U" shape and is inverted on the base plate 100. The base plate 100 extends outward from the end of the adjustable support plate 700 to form a limiting protrusion, and the inner wall of the limiting protrusion corresponding to the end of the adjustable support plate 700 has a limiting groove.

[0058] Optionally, a roller is installed at the bottom of the adjustable support plate 700 to reduce friction during the position adjustment of the adjustable support plate 700 .

[0059] In this embodiment, adjusting members 110 are rotatably mounted at both ends of the base plate 100 , and the adjusting members 110 are drivingly connected to the ends of the adjustable support plates 700 . The adjusting members 110 are rotated to drive the two sets of adjustable support plates 700 to move toward or away from each other.

[0060] In this embodiment, the adjusting member 110 includes a driving screw 112 and an adjusting dial 114. The spiral grooves at both ends of the driving screw 112 have opposite rotation directions. The two ends of the driving screw 112 are respectively threaded through the ends of the two sets of adjustable support plates 700 and are fixedly connected to the adjusting dial 114.

[0061] Preferably, see Figure 7The surface of the base plate 100 corresponding to the driving screw 112 has a support block, and a limit groove is provided in the support block. A limit block is provided on the rod body between the driving screw 112 and the adjusting dial 114. The limit block is engaged and rotatably installed in the limit groove. On the one hand, the driving screw 112 is supported, and on the other hand, the position of the driving screw 112 is limited.

[0062] Optionally, the drive screws 112 are provided in two groups, and the spiral grooves on the two groups of drive screws 112 have opposite rotation directions.

[0063] Specifically, based on the above-mentioned embodiment, the driving of the placement wheels 300 on both sides is set separately, so that the spacing between the placement wheels 300 on both sides is adjustable. When it is necessary to adjust the spacing between the placement wheels 300 according to the size of the steel mold, the adjustment dial 114 is rotated, and the adjustment dial 114 drives the driving screw 112 to rotate synchronously. The spiral grooves at both ends of the driving screw 112 respectively drive the two sets of adjustable support plates 700 to translate along the top of the bottom plate 100 to adjust the spacing between the placement wheels 300.

[0064] Since the placement wheel 300 can be reciprocated, the base plate 100 is fixed, and the hoisting position of the steel formwork with concrete is generally fixed, it is necessary to adjust the position of the placement wheel 300 when placing the steel formwork.

[0065] like Figure 5 and Figure 6 As shown, in one embodiment, the adjustable support plate 700 includes a movable plate 710, an adjustment plate 720 and an abutment claw 730, the adjustment plate 720 is slidably mounted on the top of the movable plate 710, the abutment claw 730 is slidably mounted at one end of the adjustment plate 720, the abutment claws 730 on the two sets of adjustment plates 720 are respectively located at the two ends of the movable plate 710, and the drive screw 112 is threaded through the two ends of the movable plate 710.

[0066] In this embodiment, a driving cylinder 712 is installed at one end of the moving plate 710 corresponding to the abutting claw 730 , and a driving end of the driving cylinder 712 is connected to a corresponding end of the adjusting plate 720 .

[0067] In this embodiment, a distance sensor 732 is fixedly installed on the inner wall of the abutment claw 730, and a driving rod is fixedly installed on the bottom end of the abutment claw 730. The end of the driving rod has a spherical connection part. The surface of the placement wheel 300 adjacent to the driving rod has a traction groove, which matches the shape of the spherical connection part and is arranged in a ring shape. The spherical connection part is slidably installed in the traction groove of the placement wheel 300 adjacent to it.

[0068] Preferably, the top of the bottom plate 100 has an adjustment groove 101, and the surface of the adjustment plate 720 corresponding to the adjustment groove 101 has an adjustment slider 722, and the adjustment slider 722 is installed in the adjustment groove 101 by sliding to enable the adjustment plate 720 to slide on the top of the movable plate 710.

[0069] Specifically, in the process of placing the steel formwork poured with concrete on the placement wheel 300, the driving cylinder 712 is first started to pull the adjustment plate 720 to move in opposite directions. The adjustment plate 720 drives the placement wheel 300 and the abutment claws 730 to move outward synchronously through the rifle rod 200 to increase the distance between the two sets of abutment claws 730, ensuring that the steel formwork can fall between the two sets of abutment claws 730 during the lifting process.

[0070] When the steel mold is lowered between the abutment claws 730, the driving cylinder 712 is started to push the adjustment plates 720 to move toward each other. The adjustment plates 720 drive the two groups of abutment claws 730 to move toward the hoisted steel mold together, so that the distance sensors 732 on the abutment claws 730 abut against one end of the steel mold. When the monitoring value of one group of distance sensors 732 reaches the preset value, the group of distance sensors 732 outputs a pause command to the driving cylinder 712. When the monitoring value of the other group of distance sensors 732 reaches the preset value, a pause command is output to the driving cylinder 712. At this time, the placement wheels 300 on both sides are symmetrically distributed on both sides of the steel mold to facilitate the alignment of the steel mold and its placement on the placement wheels 300. In this process, since the abutment claws 730 are slidably installed on the placement wheels 300 through the driving rod, the abutment claws 730 can be displaced synchronously with the placement wheels 300, and then the distance between the abutment claws 730 and the end of the steel mold is limited to ensure that the steel mold is aligned and placed on the placement wheels 300.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
