Technical Field
[0001] The present application relates to the technical field of box girder prefabrication, and in particular to a transversely movable pedestal for box girder prefabrication. Background Art
[0002] Traditional box girder prefabrication mostly uses fixed pedestals, and the templates need to be hoisted and assembled during construction. After the box girder is prefabricated, it needs to be transported to the beam storage area by a beam transport vehicle or a gantry crane. The process of hoisting the template and lifting the beam requires the coordination of lifting equipment and transportation equipment, but hoisting has corresponding safety risks and the hoisting and lifting efficiency is low, which affects the progress of box girder construction.
[0003] In the prior art, in order to improve the construction progress of the box beam, a mobile pedestal is used to prefabricate the box beam. For example, the Chinese patent document with the publication number CN218203890U discloses a box beam prefabrication transverse mobile pedestal, which includes several transverse tracks arranged on the transverse concrete track foundation and three segments connected together; each segment is provided with active running wheels on both sides and a driven running wheel in the middle; the active running wheels and the driven running wheels are both arranged on the transverse tracks, and the active running wheels are connected to a running motor with a reducer; the running motor is connected to a remote controller; two longitudinal tracks for placing the mobile box beam prefabrication pedestal are arranged in parallel at the top center of the three segments; box beam support rods supporting the ears of the prefabricated box beam are arranged on both sides of the three segments. By setting two longitudinal tracks, several transverse tracks, and active running wheels and driven running wheels arranged on the several transverse tracks, the transverse movement of the prefabricated box beam can be realized quickly and efficiently.
[0004] In the above-mentioned related technologies, since the box girder is prefabricated directly on the surface of the moving pedestal, and then the box girder is moved to the beam storage area under the action of the moving trolley, it is necessary to remove the prefabricated box girder from the surface of the moving pedestal; since the concrete is directly on the surface of the moving pedestal, when the box girder is finally removed, it will be difficult to separate the box girder from the surface of the moving pedestal. At the same time, after the box girder is separated from the surface of the moving pedestal, concrete will be left on the surface of the moving pedestal, which makes it very inconvenient to clean the concrete on the surface of the moving pedestal. Summary of the invention
[0005] The present application provides a prefabricated transverse movable pedestal for box beams, aiming to solve the problem in the related art that it is inconvenient to remove the box beams from the surface of the movable pedestal.

Since the support plates move piece by piece, the prefabricated box beam can still be supported when other support plates do not move. At this time, since the rotating belt separates from the bottom surface of the prefabricated box beam in sequence, the prefabricated box beam can be removed from the movable pedestal more conveniently. At the same time, the rotating belt rotates, and the concrete on the surface of the rotating belt is cleaned under the action of the cleaning plate, thereby achieving the purpose of facilitating the cleaning of the concrete on the surface of the movable pedestal.

[0009] By adopting the above technical solution, under the action of the driving cylinder, the support plate at the outermost edge can be driven to move away from or close to the prefabricated box girder, and then under the action of the linkage component, the purpose of sequentially mobilizing the movement of the support plates can be achieved.

[0011] By adopting the above technical solution, under the action of the limit groove and the limit block, after the support plate is reset, the movable sleeve is still in the state of moving toward the support plate, and then the purpose of sequential movement of the support plate can be achieved.
[0012] Optionally, the limit groove includes a vertical portion, a first inclined portion, a bent portion and a second inclined portion, and the vertical portion, the first inclined portion, the bent portion and the second inclined portion are connected end to end. When the support plate moves in a direction away from the prefabricated box girder, the limit block slides in the vertical portion; and a pushing member is provided in the fixed sleeve for pushing the movable sleeve to move toward the bottom wall of the support plate.
[0013] By adopting the above technical scheme, when the driving cylinder drives the support plate at the edge to move downward, the support plate drives the connecting rod to move when it moves, and then the connecting rod pushes the moving sleeve to move, and the moving sleeve drives the limit block to move, and when the support plate moves away from the prefabricated box beam, the limit block moves in the vertical part and the first inclined part, and when the support plate moves to the farthest distance, the limit block is at the connection point between the first inclined part and the bending part, and then when the support plate moves in the opposite direction, the limit block moves in the bending part. At this time, due to the sliding of the connecting rod on the moving sleeve, the support plate is first reset under the action of the driving cylinder, and at this time the moving sleeve moves slowly under the action of the pushing member, and finally resets. In the process of slow movement of the moving sleeve, the driving assembly is driven to work, and the adjacent support plates are driven by the driving assembly to move in the direction away from the prefabricated box beam, thereby achieving the purpose of moving the support plates in sequence.

Four support rollers 11 are provided. Under the action of the four support rollers 11, the rotating belt 12 is in an inverted trapezoidal structure, and the rotating belt 12 presents two horizontal parts on the moving pedestal body 01, one horizontal part is on the upper surface of the moving pedestal body 01, and the bottom surface of the prefabricated box beam abuts on the surface of the rotating belt 12; a motor is provided on the moving pedestal body 01, and the output shaft of the motor is connected to one of the support rollers 11, and the rotating belt 12 can be driven to rotate by the rotation of the motor; the cleaning plate 04 on the moving pedestal body 01 is provided on the side and abuts on the surface of the rotating belt 12, and when the rotating belt 12 rotates, the concrete on the surface of the rotating belt 12 can be cleaned, thereby achieving the purpose of easy cleaning.
[0033] Reference Figure 3-Figure 8The support assembly 03 includes a plurality of support plates 031 slidably connected to the movable pedestal body 01, the support plates 031 are arranged on the lower surface of the rotating belt 12, and the lower surface of the rotating belt 12 abuts on the upper surface of the support plates 031, and the rotating belt 12 is slidably connected to the support plates 031. A control mechanism is arranged on the movable pedestal body 01, and the control mechanism is used to drive the plurality of support plates 031 to move in a direction away from the prefabricated box beam in sequence. When the support plates 031 move, the rotating belt 12 sliding on the support plates 031 will move away from the prefabricated box beam. One side of the prefabricated box beam is convex. When the front support plate 031 moves away from the prefabricated box beam under the action of the control mechanism, the rotating belt 12 at the corresponding position will convex to the side away from the prefabricated box beam, and the rotating belt 12 here will be separated from the bottom surface of the prefabricated box beam. Then the control mechanism resets the support plate 031. After the support plate 031 is reset, it can still support the box beam. At this time, the adjacent support plates 031 will move away from the prefabricated box beam, thereby facilitating the separation of the corresponding prefabricated box beam and the rotating belt 12.
[0034] Reference Figure 3-Figure 8 The control mechanism includes a driving cylinder 05 and multiple linkage components 2 arranged on the moving platform. The piston rod of the driving cylinder 05 is fixed on the support plate 031 at the edge, and the multiple linkage components 2 correspond to the multiple support plates 031 one by one; the linkage component 2 includes a linkage rod 21 rotatably connected to the support plate 031, a movable sleeve 22 slidably connected to the linkage rod 21, and a fixed sleeve 23 fixed on the moving platform body 01. The movable sleeve 22 is sleeved on the linkage rod 21, and when the movable sleeve 22 rotates, it can drive the linkage rod 21 to rotate on the support plate 031, and in the initial state, the support plate 031 supports the rotating belt 12. At this time, the linkage rod 21 is in contact with the bottom of the movable sleeve 22, and then when the support plate 031 moves, the support plate 031 drives the linkage rod 21 to move, and then the linkage rod 21 can push the movable sleeve 22 to move at the same time.
[0035] Reference Figure 3-Figure 8 , a limit ring 06 is installed in the fixed sleeve 23, a limit groove 3 is provided on the limit ring 06, a limit block 4 is slidably connected in the limit groove 3, and the limit block 4 is fixedly installed on the movable sleeve 22. By setting the limit groove 3, the moving path of the movable sleeve 22 can be limited. At the same time, a pusher 41 is provided in the fixed sleeve 23, and the pusher 41 is used to push the movable sleeve 22 to move in the direction close to the prefabricated box beam. In this embodiment, the pusher 41 is set as a reset spring 411, one end of the reset spring 411 is fixed on the bottom wall of the movable sleeve 22, and the other end is fixed on the inner wall of the fixed sleeve 23. When the support plate 031 moves, the linkage rod 21 moves the movable sleeve 22, and at this time, the movable sleeve 22 will compress the reset spring 411, and then when the support plate 031 moves in the reverse direction, the reset spring 411 can push the movable sleeve 22 to move in the reverse direction.
[0036] Reference Figure 3-Figure 8 The limiting groove 3 includes a vertical portion 31, a first inclined portion 32, a bending portion 33 and a second inclined portion 34. The vertical portion 31, the first inclined portion 32, the bending portion 33 and the second inclined portion 34 are connected end to end. The first inclined portion 32, the bending portion 33 and the second inclined portion 34 are all arranged along the circumference of the limiting ring 06, and the vertical portion 31, the first inclined portion 32, the bending portion 33 and the second inclined portion 34 are arranged along the limiting ring 06 for one circle, thereby dividing the limiting ring 06 into two upper and lower parts. In this embodiment, the bending portion 33 is arranged as a wave-shaped structure. A driving assembly 5 is arranged on the moving sleeve 22. After the moving support plate 031 is reset, the driving assembly 5 can drive the adjacent support plate 031 to move in a direction away from the prefabricated box beam, thereby realizing that after the previous support plate 031 is reset, the next adjacent support plate 031 can still be driven to move.
[0037] Reference Figure 3-Figure 8 In the initial state, the stopper 4 is at the connection between the vertical portion 31 and the second inclined portion 34. At this time, the support plate 031 can support the rotating belt 12. Then, when the support plate 031 moves in the direction away from the prefabricated box beam, the movable sleeve 22 drives the stopper 4 to move, so that the stopper 4 slides in the vertical portion 31. Then, after the support plate 031 drives the rotating belt 12 and the bottom surface of the prefabricated box beam to separate, the stopper 4 is at the connection between the first inclined portion 32 and the bending portion 33. When the support plate 031 needs to be reset, the driving cylinder 05 directly drives the support plate 031 to move in the opposite direction. Then, after the support plate 031 is reset, since the stopper 4 moves in the bending portion 33, the reset spring 411 will push the movable sleeve 22 to move. When the support plate 031 moves in the opposite direction, due to the setting of the vertical portion 31 and the bending portion 33, the purpose of first resetting the support plate 031 and then slowly resetting the movable sleeve 22 can be achieved.
[0038] Reference Figure 3-Figure 8 The driving assembly 5 includes an active rack 51 arranged on the movable sleeve 22, a rotating gear 52 rotatably connected to the movable platform body 01, and a driven rack 53 fixed on the adjacent support plate 031. A pushing assembly 6 is arranged on the fixed sleeve 23, and the pushing assembly 6 is used to push the active rack 51 to move toward or away from the rotating gear 52.
[0039] Reference Figure 3-Figure 8The pushing component 6 is fixed to a limiting rod 61 on the moving sleeve 22, a moving rod 62 slidably connected to the limiting rod 61, and a mounting rod 63 fixed to the moving rod 62. The mounting rod 63 is arranged along the axial direction of the rotating gear 52. The active rack 51 is fixed to the moving rod 62. At the same time, a pushing block 8 is slidably connected to the mounting rod 63. A mounting plate 9 is fixedly installed on the fixed sleeve 23. A pushing groove 7 is provided on the mounting plate 9. The pushing block 8 is slidably connected in the pushing groove 7. At the same time, a pushing spring 42 is fixedly installed in the limiting rod 61 to push the active rack 51 to move away from the rotating gear 52. One end of the pushing spring 42 is fixed to the limiting rod 61, and the other end is fixed to the moving rod 62.

The first pushing portion 71, the first connecting portion 72, the second pushing portion 73, the third pushing portion 74 and the second connecting portion 75 are connected end to end, and the depth of the first pushing portion 71 is the same as the depth of the second pushing portion 73, the depth of the third pushing portion 74 is less than the depth of the pushing portion, and the second connecting portion 75 is inclined to facilitate the pushing block 8 in the third pushing portion 74 to move into the first pushing portion 71; when the moving sleeve 22 moves downward, under the action of the pushing spring 42, the pushing block 8 slides in the first pushing portion 71, at which time the active rack 51 and the rotating gear 52 are separated, and then when the moving sleeve 22 moves away from the support plate 031, it will not drive the rotating gear 52 to rotate, and at this time, it will not drive the adjacent support plate 031 to move.
[0041] Reference Figure 3-Figure 8 When the support plate 031 is reset, since the limit block 4 slides in the bending portion 33, the movable sleeve 22 is still in the effect of moving towards the support plate 031 under the action of the reset spring 411. When the movable sleeve 22 moves in the opposite direction, it will drive the limit rod 61 and the movable rod 62 to move, and the movement of the movable rod 62 drives the active gear to move. At this time, since the pushing block 8 is in the second pushing portion 73, the second pushing portion 73 will push the active rack 51 to move in the direction close to the rotating gear 52, and then make the active rack 51 and the rotating gear 52 mesh, and then when the movable sleeve 22 moves in the opposite direction, it can drive the rotating gear 52 to move, and the rotating gear 52 drives the driven rack 53 to move in the opposite direction, and then drives the support plate 031 to move in the direction away from the prefabricated box beam, thereby achieving the purpose of multiple support plates 031 driving the rotating belt 12 to separate from the bottom surface of the prefabricated box beam in sequence.
[0042] Reference Figure 3-Figure 8In this embodiment, an inclined structure is set between the second pushing portion 73 and the third pushing portion 74, so as to facilitate the pushing block 8 in the second pushing portion 73 to move to the third pushing portion 74. When the limit block 4 slides in the bending portion 33, the support frame has not yet reset. At this time, the pushing block 8 is in the second pushing portion 73, and the active rack 51 and the rotating gear 52 have not yet engaged. When the support plate 031 is reset, the limit block 4 is still in the bending portion 33. At this time, the pushing block 8 is in the third pushing portion 74, and then the active rack 51 is pushed to move in the direction close to the rotating gear 52, thereby making the active rack 51 and the rotating gear 52 engage, and then it is convenient to drive the adjacent support plate 031 to move in the opposite direction through the movement of the active rack 51.
[0043] The implementation principle of a box girder prefabrication transverse moving pedestal in the embodiment of the present application is as follows: when separating the prefabricated box girder and the rotating belt 12, the driving cylinder 05 drives the support plate 031 at the edge to move downward, and when the support plate 031 moves, it drives the connecting rod 21 to move, and then the connecting rod 21 pushes the moving sleeve 22 to move, and the moving sleeve 22 drives the limit block 4 to move, and when the support plate 031 moves away from the prefabricated box girder, the limit block 4 moves in the vertical portion 31 and the first inclined portion 32, and when the support plate 031 moves to the farthest distance, the limit block 4 is at the connection between the first inclined portion 32 and the bending portion 33, and then when the support plate 031 moves in the opposite direction, the limit block 4 It moves in the bending portion 33. At this time, since the connecting rod 21 slides on the movable sleeve 22, the support plate 031 is first reset under the action of the driving cylinder 05. At this time, the movable sleeve 22 moves slowly under the action of the pushing member 41, and finally resets. In the process of the slow movement of the movable sleeve 22, the driving component 5 is driven to work, and the adjacent support plates 031 are driven by the driving component 5 to move in the direction away from the prefabricated box beam, thereby achieving the purpose of moving the support plates 031 in sequence; in addition, since a cleaning plate is abutted on the surface of the rotating belt 12, the concrete on the surface of the rotating belt 12 can be cleaned when the rotating belt 12 rotates, thereby achieving the purpose of easy cleaning.
