Description

Technical Field

[0001] This invention relates to the field of pedestrian bridge construction technology, specifically a box-type steel structure pedestrian bridge hoisting and stabilization device. Background Technology

[0002] In modern urban construction, pedestrian overpasses are increasingly widely used as important facilities to ensure pedestrian safety and alleviate traffic congestion. Box-type steel structure pedestrian overpasses, due to their advantages such as high strength, short construction period, and aesthetically pleasing design, have become the preferred choice for many cities. However, the hoisting process for box-type steel structure pedestrian overpasses faces numerous challenges, placing extremely high demands on the hoisting stabilization devices.

[0003] The main structure of a box-type steel structure pedestrian bridge is based on a box-shaped cross-section (a closed rectangular or trapezoidal cross-section formed by welding steel plates). Its auxiliary structures (such as beams, supports, and connecting nodes) often use I-beams. I-beams have excellent cross-sectional properties (strong bending resistance and light weight) and are easy to process, making them suitable as lateral supports, longitudinal connecting beams, or local load-bearing components for pedestrian bridges to enhance the stability of the box-type main structure.

[0004] However, existing hoisting equipment is not convenient for securing and clamping I-beams during hoisting, and they are prone to falling off during the hoisting process, resulting in poor stability and serious safety hazards.

[0028] The present invention will be further explained below with reference to specific embodiments.

[0029] Please see Figures 1-7 The present invention provides a box-type steel structure pedestrian bridge hoisting and stabilizing device, which includes: The control box 1 is provided with a suspension component 2 that is connected to the hook of the crane; wherein the crane can be any existing technology, and the crane can also be replaced by other equipment according to actual needs, such as gantry crane, etc., which are not specifically limited here.

Compared with the prior art, the present invention, through the cooperative setting of the bidirectional drive component and the clamping mechanism, can further improve the stability during hoisting, avoiding the problem that existing hoisting devices are not convenient for fixing and clamping the I-beam when hoisting it, and the phenomenon of easy falling off during hoisting, which poses a serious safety hazard.

[0031] In one embodiment of the present invention, please refer to Figures 1-7 The support member includes: A suspension plate 6 is slidably installed at the bottom of the control box 1. Multiple suspension plates 6 are provided, and the suspension plates 6 have an inverted T-shaped structure. And a horizontal plate 5 fixedly installed at the bottom of the suspension plate 6, wherein the horizontal plate 5 has a receiving cavity for installing a self-locking drive assembly; The multi-functional clamping assembly includes: A support box 4 is fixedly installed on the horizontal plate 5. A translation frame 12 is slidably installed inside the support box 4, and an adjustment component for controlling the position of the translation frame 12 is also provided inside the support box 4. The support shaft 21 is rotatably mounted on the translation frame 12. Two sets of support shafts 21 are symmetrically arranged inside the translation frame 12, and side support rods 3 are fixedly installed on both sets of support shafts 21. A pressing wheel 13 is used to press the I-beam, and the pressing wheel 13 is rotatably mounted on the end of the side support rod 3; Linkage gear 20, one of each of the two sets of support shafts 21 is fixedly installed, and the two linkage gears 20 mesh with each other; And the elastic support assembly set between the two sets of side struts 3; The elastic support component includes: Support base 25, two of which are provided on each set of side support rods 3, and a support rod 24 is rotatably installed between the two side support rods 3; And an elastic sheet 22, the two ends of which are fixedly connected to two support rods 24 respectively, and the elastic sheet 22 has an arc-shaped structure when not under stress; The adjustment component includes: One-way threaded rod 18, at least one set of one-way threaded rods 18 is rotatably installed in the support box 4, and the translation frame 12 is provided with an internal threaded hole that is threadedly connected to the one-way threaded rod 18. And a rotating shaft 16 is rotatably mounted on the side wall of the support box 4. A drive gear 15 is fixedly mounted on the rotating shaft 16, and a driven gear 17 that meshes with the drive gear 15 is fixedly mounted on the one-way threaded rod 18. A worm gear 14 is fixedly mounted on the end of the rotating shaft 16 away from the drive gear 15. The self-locking drive component includes: The worm 10 meshes with the worm gear 14 and is rotatably mounted inside the horizontal plate 5; And a second drive member 11 for driving the worm gear 10 to rotate; wherein the second drive member 11 may be a knob fixedly connected to the worm gear 10, and the second drive member 11 may also be a motor, which is not specifically limited here; The multi-functional clamping assembly also includes: A guide rod 26 is fixedly installed inside the support box 4. A rack 19 is slidably installed on the guide rod 26, and the cross section of the guide rod 26 is rectangular. A spring 27 is used to elastically pull the rack 19. One end of the spring 27 is fixedly connected to the guide rod 26, and the other end of the spring 27 is fixedly connected to the rack 19. And a control gear 23 fixedly installed on one of the support shafts 21. The control gear 23 meshes with the rack 19. When the control gear 23 moves with the translation frame 12 toward the worm gear 14, the control gear 23 drives the support shaft 21 to rotate under the meshing action with the rack 19, so that the support shaft 21 drives the side support rod 3 to squeeze the elastic sheet 22.

[0032] In this embodiment, when the two sets of horizontal plates 5 approach each other, the horizontal plates 5 can drive the support box 4 and the translation frame 12 to move, so that the pressing roller 13 presses against both sides of the I-beam. By continuously approaching the I-beam, the horizontal plates 5 can make the pressing roller 13 move along the vertical surface of the middle of the I-beam, and the side support rod 3 will rotate around the support shaft 21. With the meshing of the two linkage gears 20, the two side support rods 3 will rotate synchronously, thereby increasing the included angle between the two side support rods 3 until the pressing roller 13 presses against the inner top and inner bottom of the I-beam, thus achieving the fixing of the I-beam. During material unloading, the second driving member 11 drives the worm gear 10 to rotate. The second driving member 11 will drive the rotating shaft 16 to rotate through the worm wheel 14. The rotating shaft 16, through its cooperation with the driving gear 15, can drive the driven gear 17 to rotate. The driven gear 17 drives the one-way threaded rod 18 to rotate, thereby driving the translation frame 12 to move one side of the worm wheel 14. The control gear 23, in meshing with the rack 19, drives the support shaft 21 to rotate, so that the support shaft 21 drives the side support rods 3 to squeeze the elastic plate 22, causing the included angle between the two side support rods 3 to gradually decrease. At this time, the vertical surface of the middle part of the I-beam can move down between the relative pressing rollers 13, so that the bottom of the I-beam can move down, making it easier for the workers to unload the I-beams in the multiple clamping mechanisms in sequence. With the cooperation of the spring 27 and the guide rod 26, when fixing, due to the increased included angle between the two side support rods 3, the control gear 23 can pull the rack 19 to move a certain distance to the side of the pressing roller 13, so as to avoid the rack 19 affecting the normal rotation of the support shaft 21. The support of the elastic plate 22 makes it easy for the side support rods 3 to return to their original position. The sum of the length of the two side support rods 3 and the distance between the two support shafts 21 is greater than the length from the inner top to the inner bottom of the I-beam, so that the two side support rods 3 are sufficient to support the I-beam.

[0033] In one embodiment of the present invention, please refer to Figures 1-7 The bidirectional drive component includes: A translation rod 9 is slidably installed in the control box 1, and the translation rod 9 is fixedly connected to the suspension plate 6. The bottom of the control box 1 is provided with a strip-shaped through hole for the suspension plate 6 to pass through. The bidirectional threaded rod 8 is rotatably installed in the control box 1. The translation rod 9 has an internal threaded hole that is threadedly connected to the bidirectional threaded rod 8, and the two sets of threads on the bidirectional threaded rod 8 have opposite directions of rotation. And a first driving member 7 for driving the bidirectional threaded rod 8 to rotate; wherein the first driving member 7 may be a knob fixedly connected to the bidirectional threaded rod 8, and the first driving member 7 may also be a motor, without specific limitation.

[0034] In this embodiment, by using the first driving member 7 to drive the bidirectional threaded rod 8 to rotate, the two sets of translation rods 9 can be driven to move closer and further apart, thereby adjusting the distance between the two sets of clamping mechanisms, so that the clamping mechanisms can press against both sides of the I-beam.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
