Description

Technical Field

[0001] The present application belongs to the field of construction and relates to a concrete pouring platform for building construction. Background Art

[0002] During concrete pouring, construction workers generally step directly on the floor slab steel frame, applying external loads to the already tied steel bars. The application of external loads will cause the steel bars to deform, so a concrete pouring platform is usually used to provide construction workers with operating space.

[0003] Patent CN219011872U discloses a concrete pouring platform, comprising a support frame and a panel assembly mounted on the support frame. The panel assembly comprises a main panel and four movable panels distributed on the sides of the main panel. The movable panels rotate relative to the main panel and are locked to the main panel. The movable panels rotate to a position flush with the main panel to form an unfolded platform. To expand the area of ​​the pouring platform and unfold the movable panels, the support plate is rotated away from the chute and slid toward the main panel until the top of the support plate abuts the bottom surface of the movable panel. To retract the movable panels to form a guardrail, the support plate is slid away from the main panel to the bottom of the chute and rotated until the support plate is embedded in the chute.

[0004] However, the height of the above-mentioned concrete pouring platform is fixed and cannot cope with the pouring operation of cast-in-place slabs with different slab thicknesses. Summary of the Invention

[0015] Preferably, the lifting rod includes a screw rod, which is slidably arranged on an auxiliary support column along the height direction. The auxiliary support column is rotatably provided with a nut, and the nut cooperates with the screw thread.

A transmission mechanism is provided between the nut and the driving gear, and the driving gear can drive the nut to rotate through the transmission mechanism.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-7 This application is described in further detail.

[0034] like Figure 1 、 Figure 2 As shown, the concrete pouring platform includes a main platform 1, main support columns 2, auxiliary platform 3, connecting parts 4, and auxiliary support columns 5.

[0035] Among them, the main support column 2 is located below the main platform 1, close to the corner of the main platform 1, and the upper end of the main support column 2 is fixedly connected to the lower plate surface of the main platform 1. The specific connection method can be welding or bolts.

[0036] In this embodiment, an accommodating cavity 21 is opened on the outer side of the main support column 2 . When the auxiliary support column 5 is located below the main platform 1 , the auxiliary support column 5 is also located in the accommodating cavity 21 .

[0037] As another solution, the auxiliary support column 5 can also be arranged outside the main support column 2.

[0038] like Figure 1 、 Figure 2 As shown, one end of the connecting member 4 is hinged to one side of the main platform 1 , and the other end of the connecting member 4 is hinged to one side of the auxiliary platform 3 .

[0039] In this embodiment, the connecting member 4 includes a main plate body 41 and an auxiliary plate body 42. The end of the main plate body 41 close to the main table plate 1 is hinged to the main table plate 1, the end of the main plate body 41 away from the main table plate 1 is slidingly connected to the end of the auxiliary plate body 42 away from the auxiliary table plate 3, and the end of the auxiliary plate body 42 close to the auxiliary table plate 3 is hinged to the auxiliary table plate 3.

[0040] Specifically, a sliding groove 43 is formed at one end of the auxiliary plate body 42 away from the auxiliary platform plate 3 , and an end of the main plate body 41 away from the main platform plate 1 is inserted into the sliding groove 43 and slidably cooperates with the main plate body 41 .

[0041] Preferably, a locking mechanism 44 is provided between the main plate body 41 and the auxiliary plate body 42 to enable the two to be relatively fixed or loosened.

[0042] In this embodiment, a plurality of threaded holes are provided on the side wall of the auxiliary plate body 42 along the sliding direction, and the threaded holes are connected to the slide groove 43. The locking mechanism 44 includes a locking screw 441 threadedly connected to the threaded hole. By rotating the locking screw 441, the locking screw 441 is pressed against the side wall of the main plate body 41, so that the main plate body 41 and the auxiliary plate body 42 are relatively fixed. By rotating the locking screw 441 in the opposite direction, the locking screw 441 is separated from the side wall of the main plate body 41, so that the main plate body 41 and the auxiliary plate body 42 are in a relatively loose state.

[0043] As another solution, a number of limiting holes can also be opened on the side wall of the main plate body 41. The limiting holes are distributed along the sliding direction of the main plate body 41. The auxiliary plate body 42 is provided with a limiting through hole that can be aligned with any limiting hole. The locking mechanism 44 includes a limiting pin that can pass through the limiting through hole and be inserted into the limiting hole. The limiting through hole is aligned with different limiting holes to adapt to the relative sliding between the main plate body 41 and the auxiliary plate body 42. The limiting pin is inserted into the limiting through hole and the limiting hole to achieve relative fixation of the main plate body 41 and the auxiliary plate body 42. The limiting pin is removed to achieve relative loosening of the main plate body 41 and the auxiliary plate body 42.

[0044] In addition to being configured as a combination structure of the main plate body 41 and the auxiliary plate body 42 , the connecting member 4 can also be configured as a separate plate body. Of course, it can also be configured as a rod-shaped structure.

[0045] like Figure 3 、 Figure 4 As shown, a translation mechanism 6 is provided between the auxiliary support column 5 and the main support column 2 , and the translation mechanism 6 can drive the auxiliary support column 5 to move back and forth in the horizontal direction below the main platform 1 and below the auxiliary platform 3 .

[0046] In this embodiment, the translation mechanism 6 includes a motor 61, a driving gear 62 and a rack 63. The motor 61 is fixed on the main support column 2, the driving gear 62 is arranged on the output shaft 64 of the motor 61, and a mounting seat 65 is provided on the main support column 2. The output shaft 64 is rotatably set on the mounting seat 65. The rack 63 is slidingly set on the main support column 2 along the horizontal direction. The teeth of the rack 63 are set upward. The length direction of the rack 63 is consistent with the moving direction of the auxiliary support column 5. The driving gear 62 is located above the rack 63 and can engage with the rack 63. One end of the rack 63 is fixed to the auxiliary support column 5.

[0047] When the driving gear 62 is engaged with the rack 63 , the output shaft 64 of the motor 61 rotates, driving the driving gear 62 to rotate, driving the rack 63 to move, and causing the auxiliary support column 5 to move relative to the main support column 2 .

[0048] As another solution, the translation mechanism 6 includes a cylinder arranged in the horizontal direction, the cylinder body of the cylinder is fixed on the main support column 2, the piston rod of the cylinder is connected to the auxiliary support column 5, and the piston rod of the cylinder is telescopic to drive the auxiliary support column 5 to move.

[0049] like Figure 5 、 Figure 6 As shown, the auxiliary support column 5 is provided with a lifting rod 7 that can move back and forth in the height direction. When the lifting rod 7 rises, the upper end of the lifting rod 7 can push the auxiliary platform 3 to move.

[0050] In this embodiment, the lifting rod 7 includes a screw 71, which is slidably arranged on the auxiliary support column 5 along the height direction. The auxiliary support column 5 is rotatably provided with a nut 72, which is threadedly engaged with the screw 71. The nut 72 can drive the screw 71 to move back and forth in the height direction by rotation.

[0051] Specifically, if Figure 7 As shown, the auxiliary support column 5 is provided with an annular groove 52, and the upper end of the nut 72 has an annular boss 721, which is coaxially arranged with the annular groove 52 and rotatably engaged with the annular groove 52. The lower end of the screw rod 71 has a square stopper 711, and the lower section of the auxiliary support column 5 has a square groove 51 that cooperates with the stopper 711, so that the screw rod 71 is circumferentially positioned relative to the auxiliary support column 5. When the nut 72 rotates, the screw rod 71 can only move in the height direction.

[0052] like Figure 5 、 Figure 6 As shown, a transmission mechanism 8 is provided between the nut 72 and the driving gear 62 , and the driving gear 62 can drive the nut 72 to rotate through the transmission mechanism 8 .

[0053] In this embodiment, the transmission mechanism 8 includes a driven gear 81, a main pulley 82, a slave pulley 83, a transmission belt 84, a main bevel gear 85 and a slave bevel gear 86. The driven gear 81 is rotatably arranged at the end of the rack 63 away from the auxiliary support column 5. The driving gear 62 can engage with the driven gear 81. The main pulley 82 is coaxially connected to the driven gear 81 through a transmission shaft 1 87. The main pulley 82 is connected to the slave pulley 83 through a transmission belt 84. The slave pulley 83 is coaxially connected to the main bevel gear 85 through a transmission shaft 2 88. The transmission shaft 2 88 is rotatably arranged on the auxiliary support column 5. The slave bevel gear 86 is coaxially fixed to the nut 72, and the slave bevel gear 86 engages with the main bevel gear 85.

[0054] When the driving gear 62 is meshed with the driven gear 81 , the motor 61 drives the nut 72 to rotate through the driving gear 62 , the driven gear 81 , the driving pulley, the transmission belt 84 , the driven pulley, the main bevel gear 85 , and the driven bevel gear 86 in sequence.

[0055] As another solution, the main pulley 82, the slave pulley 83, and the transmission belt 84 can also be replaced by two mutually meshing gears.

[0056] like Figure 5 、 Figure 6 As shown, the driving gear 62 is slidably arranged on the output shaft 64 of the motor 61 and the two are relatively positioned in the circumferential direction. In this embodiment, the output shaft 64 is provided with a limit bar 641 along the axial direction, and the inner hole of the driving gear 62 has a limit groove 621 that cooperates with the limit bar 641, so that the driving gear 62 is fixed relative to the circumference of the output shaft 64 and can slide in the axial direction.

[0057] like Figure 5 、 Figure 6 As shown, the main plate 1 is provided with a pushing mechanism 9 capable of pushing the driving gear 62 to move axially along the output shaft 64 . The driving gear 62 can selectively engage between the rack 63 and the driven gear 81 by moving axially along the output shaft 64 .

[0058] In this embodiment, the pushing mechanism 9 includes a linear drive source 91 and a bracket 92. The linear drive source 91 is fixed to the main table 1. The bracket 92 includes a slider 921 slidably set on the main table 1. The driving shaft of the linear drive source 91 is connected to the slider 921. Push plate assemblies 93 are fixed at both ends of the slider 921. The driving gear 62 is located between the two push plate assemblies 93. The push plate assembly 93 can contact the driving gear 62 and push the driving gear 62 to slide.

[0059] Specifically, the linear drive source 91 can be an oil cylinder or a linear motor 61, and the push plate assembly 93 includes a vertical plate 931 and a side plate 932. The upper end of the vertical plate 931 is fixed to the end of the slider 921, and a guide rod 933 is arranged at the lower end of the vertical plate 931 in the horizontal direction. The side plate 932 is located between the vertical plate 931 and the driving gear 62, and is slidably arranged on the guide rod 933. A compression spring 934 is arranged between the side plate 932 and the vertical plate 931.

[0060] When the side plate 932 pushes the driving gear 62 to engage with the rack 63 or the driven gear 81, if the teeth on the driving gear 62 are not in corresponding positions with the teeth of the latter two, and the linear drive source 91 is still pushing the vertical plate 931, the compression spring 934 can reduce the wear between the side plate 932, the driving gear 62, the rack 63 or the driven gear 81 by deformation.

[0061] In order to realize the movement of the lifting rod 7, as another solution, the lifting rod 7 can also be designed as a push rod structure, and the push rod is slidably set on the auxiliary support column 5 and driven by a cylinder or a scissor-type lifting platform.

[0062] The working principle of this embodiment is as follows:

[0063] In normal use, such as Figure 3 As shown, the main support column 2 supports the main platform 1, and the auxiliary support column 5 is located below the main platform 1. The auxiliary platform 3 loses the support of the auxiliary support column 5 and is in a vertical state under the action of gravity. The driving gear 62 and the driven gear 81 are at a certain distance, and the driving gear 62 is engaged with the rack 63.

[0064] When it is necessary to expand the pouring platform area, such as Figure 5 As shown, the motor 61 drives the rack 63 to move through the driving gear 62, pushing the auxiliary support column 5 out from under the main platform 1 and moving it outward. While the auxiliary support column 5 moves, it will slowly push the auxiliary platform 3 to swing upward. When the auxiliary support column 5 is completely moved to the bottom of the auxiliary platform 3, the auxiliary platform 3 is in a position close to the horizontal. At this time, the driven gear 81 on the rack 63 is close to the driving gear 62, and the contour of the driving gear 62 projected on the surface where the driven gear 81 is located is meshed with the driven gear 81. The linear drive source 91 pushes the slider 921 to move, so that the side plate 932 of the push plate assembly 93 pushes the driving gear 62 to move toward the direction of the driven gear 81 until the driving gear 62 is meshed with the driven gear 81. The motor 61 rotates and drives the lifting rod 7 to move upward through a series of components such as the driving gear 62 and the driven gear 81, pushing the auxiliary platform 3 to the horizontal, thereby increasing the area of ​​the casting platform.

[0065] When it is necessary to cast in-situ slabs of different thicknesses, such as Figure 1 、 Figure 6 As shown, the lifting rod 7 continues to rise, pushing the auxiliary platform 3 to move upward, presenting a height difference with the main platform 1. As the auxiliary platform 3 rises, the connecting member 4 is inclined and will not interfere with the movement of the auxiliary platform 3.

[0066] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
