Description

Technical Field

[0001] This invention relates to the technical field of bridge crane components, and more particularly to an interference-free bridge crane outrigger device and its working method. Background Technology

[0002] As a key lifting device in bridge engineering, responsible for hoisting large segmental beams and steel truss girders, the spatial interference between the outriggers of bridge deck cranes and the shear studs of steel beams has become a core technical challenge restricting construction progress and quality. Current engineering practice commonly employs a method of first cutting the shear studs or reinforcing bars to create installation space for the crane outriggers, then welding them back together after removal. However, this process has systemic quality risks: frequent violations such as incomplete welding and spot welding result in insufficient weld penetration and substandard shear strength at the interface, failing to meet design specifications. These quality defects significantly reduce the cooperative load-bearing performance between the steel beams and the concrete bridge deck, weaken the force transmission efficiency of the interface connection, pose a potential risk to the long-term service performance of the bridge structure, and seriously affect the design service life and overall life-cycle safety of the bridge structure.

[0003] A crane outrigger structure is disclosed in existing patent publication number CN222023985U, comprising, from top to bottom, an outrigger body, a stabilizing seat, a flexible layer, a rigid layer, and a shock-absorbing layer. The stabilizing seat is fixedly connected to the underside of the outrigger body, and the cross-section of the stabilizing seat is larger than the cross-section of the outrigger body. The flexible layer is laid under the stabilizing seat, and the flexible layer consists of two evenly distributed square timbers, the cross-section of which is larger than the cross-section of the stabilizing seat. The rigid layer is laid under the flexible layer, and its cross-section is the same as that of the flexible layer. The shock-absorbing layer is laid under the rigid layer, and its cross-section is larger than that of the rigid layer.

[0004] In the above technical solution, the use of longitudinal and transverse square timber and stone slag cushion can prevent the leg body and the stable seat from sliding and reduce vibration. However, this structure still cannot avoid the spatial conflict between the leg support system and the steel bars and shear studs in traditional construction, and is not suitable for the use of bridge crane legs.

[0005] Therefore, it is necessary to provide a non-interference bridge deck crane outrigger device and working method, which can optimize the construction process and ensure the coordinated stress of the steel beam and the bridge deck. Summary of the Invention

[0016] In one embodiment, the lower end of the U-shaped frame is provided with a guide groove, a slide plate is slidably fitted in the guide groove, and a collection clamp is fixedly connected to the lower end of the slide plate.

[0017] In one embodiment, a pair of oblique grooves are provided through the skateboard, and a guide rod is provided in the oblique groove. A connecting plate is fixedly connected to the inner side of the L-shaped positioning plate. The upper end of the connecting plate is slidably engaged with the bottom of the U-shaped frame, and one end of the connecting plate is connected to the guide rod.

[0018] In one embodiment, the inner side of the positioning top seat is provided with a plurality of rotating cavities, the rotating cavities extend to the positioning hole, a vertical rod is rotatably connected in the rotating cavity, and an arc-shaped baffle is fixedly connected to the lower end of the vertical rod, the arc-shaped baffle moving in the rotating cavity;

[0019] The rotating cavity is equipped with a torsion spring to control the rotation of the vertical rod.

[0020] In one embodiment, the upper end of the positioning top seat is provided with an annular groove, a drive ring is rotatably connected in the annular groove, the upper end of the vertical rod extends into the annular groove, a limiting block is fixedly connected to the upper end of the vertical rod, one end of the limiting block is provided with an arc joint surface, and a limiting groove is provided at the lower end of the drive ring, the limiting groove being adapted to the limiting block.

[0021] The limiting groove includes a receiving circular groove, the diameter of which is equal to that of the limiting circular block;

[0022] The limiting groove also includes a long arc groove, which has a long arc edge that communicates with the receiving circular groove, and the curvature of the long arc edge is adapted to the arc joint surface.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In the present invention, the workers place the support pad on the top surface of the steel beam, and several vertical support plates are inserted into the gaps of the densely distributed shear studs or steel bars, and are intertwined with each other, thereby avoiding the problem of spatial conflict with the steel bars and shear studs.

[0024] Next, the load-bearing seat is placed on the upper side of the horizontal support plate by the staff, thereby further expanding the support area and dispersing the concentrated stress transmitted by the bridge crane leg body, ensuring the stability of the leg support, avoiding interference, eliminating the need to cut the steel bars and shear studs, and ensuring the subsequent bridge deck quality; at the same time, the device is easy to pick up and take down, so that it can adapt to the cyclical construction of multiple moves of the bridge crane, ensuring construction quality and improving efficiency.

To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0044] Please see Figure 1-9 The present invention provides a technical solution: a non-interference bridge crane outrigger device and its working method, comprising a support pad 1, a load-bearing seat 2, and a bridge crane outrigger body 6.

[0045] The support pad 1 includes a horizontal support plate 101, and a plurality of vertical support plates 102 are vertically connected to the lower end of the horizontal support plate 101, with equal spacing between adjacent vertical support plates 102.

[0046] Several stiffening plates 103 are provided at the junction of the vertical support plate 102 and the horizontal support plate 101;

[0047] The support seat 2 is movably mounted on the upper side of the support pad 1;

[0048] The support seat 2 is equipped with a detachable alignment mechanism 3, which is used to position the support seat 2 on the support pad 1 and simultaneously position the bridge crane outrigger body 6 and the support seat 2.

[0049] In terms of construction process, after the steel shear studs are installed, the support pads 1 are placed on the top surface of the steel beam by the workers. Several vertical support plates 102 are inserted into the gaps between the densely distributed shear studs or steel bars and are intertwined with each other, thereby avoiding the problem of spatial conflict with the steel bars and shear studs.

[0050] Next, the staff places the support seat 2 on the upper side of the horizontal support plate 101, thereby further expanding the support area, dispersing the concentrated stress transmitted by the bridge crane outrigger body 6, ensuring the stability of the outrigger support, avoiding interference, eliminating the need to cut the steel bars and shear studs, and ensuring the subsequent bridge deck quality; at the same time, the device is easy to pick up and take down, making it adaptable to the cyclical construction of multiple moves of the bridge crane, ensuring construction quality and improving efficiency.

[0051] This application adopts a step-by-step operation mode in which the support pad 1, bearing seat 2 and bridge crane outrigger body 6 are installed sequentially after the construction of steel bars and shear nails is completed. This improves the convenience of outrigger placement and eliminates the need for cutting and welding processes, thus reducing the cost of cutting and welding.

[0052] Preferably, in order to further ensure the uniformity of force on the support seat 2 and the support pad 1, the alignment mechanism 3 installed on the outside of the support seat 2 is used to align the center position of the bridge crane outrigger body 6 installed on the support seat 2; then the center position of the support seat 2 placed on the horizontal support plate 101 is aligned, thereby ensuring that the device bears the pressure of the outrigger evenly and avoiding excessive pressure on one side caused by compressive stress deviation, which could damage the device.

[0053] The load-bearing seat 2 is designed as a rectangular box-shaped component.

[0054] Preferably, the load-bearing seat 2 disperses the concentrated stress of the bridge crane outrigger body 6 through its rigid box structure and large contact area, effectively reducing local compressive stress.

[0055] Preferably, both the support pad 1 and the load-bearing seat 2 are welded from Q355B steel plates.

[0056] The support seat 2 includes an upper top plate 201, and the alignment mechanism 3 includes a positioning top seat 301. The lower end of the positioning top seat 301 is provided with a rectangular groove that is adapted to the upper top plate 201.

[0057] The center of the positioning top seat 301 is provided with a positioning hole 302 that is compatible with the body of the bridge crane leg 6.

[0058] Preferably, when the alignment mechanism 3 is required for position alignment, the positioning top seat 301 is placed on the upper top plate 201 of the bearing seat 2. The rectangular groove is adapted to the upper top plate 201 to ensure the stability of the connection between the two. The structure is simple and easy to install and disassemble.

[0059] Preferably, a positioning hole 302 is provided through the center of the positioning top seat 301. The positioning hole 302 is adapted to the bridge crane outrigger body 6. When the bridge crane outrigger body 6 is placed, it passes through the positioning hole 302 and connects with the upper top plate 201 of the support seat 2, so as to align the center position of the bridge crane outrigger body 6 and the support seat 2. Moreover, the alignment mechanism 3 achieves the alignment function while ensuring the integrity of the support seat 2 structure, without damaging the overall structure of the support seat 2, thus ensuring the stability of the support.

[0060] The two ends of the positioning top seat 301 are fixedly connected to a U-shaped frame 4, and the two ends of the U-shaped frame 4 are fixedly connected to a pair of guide rods 401. The two ends of the U-shaped frame 4 are provided with movable L-shaped positioning plates 402. The guide rods 401 pass through the L-shaped positioning plates 402 and slide with them. A spring is sleeved on the outside of the guide rods 401.

[0061] Preferably, when it is necessary to align the relative positions of the bearing seat 2 and the support pad 1, a pair of L-shaped positioning plates 402 are pulled to expand relative displacement. Then, under the reset action of the spring, the pair of L-shaped positioning plates 402 are clamped at both ends of the horizontal support plate 101 of the support pad 1, thereby aligning the pair of long sides of the horizontal support plate 101.

[0062] The lower end of the U-shaped frame 4 is provided with a guide groove 403, and a slide plate 404 is slidably fitted in the guide groove 403. The lower end of the slide plate 404 is fixedly connected to a collection clamp 405.

[0063] Preferably, by moving a pair of sliding plates 404, the assembly clamping plate 405 is driven to clamp relative to one end of the short side of the horizontal support plate 101, thereby achieving centering and alignment of the four sides of the support pad 1. Furthermore, the L-shaped positioning plate 402 and the assembly clamping plate 405 are both engaged with the bottom of the horizontal support plate 101, thereby further fixing the support pad 1 and the load-bearing seat 2 to each other, ensuring that the subsequent relative position is accurate and will not shift.

[0064] By installing the alignment mechanism 3, the relative positions of the bridge crane outrigger body 6, the bearing seat 2, and the support pad 1 are aligned, and the bearing seat 2 and the support pad 1 are fixed relative to each other. The workers can then move the two to the next support location simultaneously without having to readjust their positions. This allows the bridge crane to move multiple times for cyclical construction. After the entire project is completed, the alignment mechanism 3, the bearing seat 2, and the support pad 1 can be disassembled in sequence for easy subsequent transportation and storage.

[0065] A pair of inclined grooves 406 are provided through the slide plate 404. A guide rod 407 is provided in the inclined groove 406. A connecting plate 408 is fixedly connected to the inner side of the L-shaped positioning plate 402. The upper end of the connecting plate 408 is slidably engaged with the bottom of the U-shaped frame 4. One end of the connecting plate 408 is connected to the guide rod 407.

[0066] Preferably, to further improve ease of operation and ensure the synchronous displacement of the pair of L-shaped positioning plates 402 and the assembly clamping plate 405, a guide rod 407 and an inclined groove 406 are provided. Specifically, the inclined groove 406 restricts the synchronous displacement of the pair of guide rods 407. When the operator pulls the pair of L-shaped positioning plates 402 to unfold, it drives the connecting plate 408 to move, the guide rod 407 moves along the inclined groove 406, and drives the sliding plate 404 and the assembly clamping plate 405 to move outward. Then, they can be clamped onto the horizontal support plate 101. Under the reset action of the spring, the pair of L-shaped positioning plates 402 are reset, and the guide rod 407 drives the assembly clamping plate 405 to move synchronously, realizing the synchronous displacement of the three, positioning and clamping them onto the horizontal support plate 101. The structure is simple and the operation is convenient.

[0067] The inner side of the positioning top seat 301 is provided with several rotating cavities, which extend to the positioning hole 302. A vertical rod 303 is rotatably connected inside the rotating cavity. An arc-shaped baffle 304 is fixedly connected to the lower end of the vertical rod 303. The arc-shaped baffle 304 moves inside the rotating cavity.

[0068] A torsion spring is installed inside the rotating cavity to control the rotation of the vertical rod 303.

[0069] Preferably, when the bridge crane needs to be moved to a new construction location, the outrigger body 6 of the bridge crane must first be lifted. Then, workers remove the bearing seat 2 and the support pad 1 and transport them to the next support location for reinstallation. The outrigger body 6 is then repositioned. To further optimize the process, several arc-shaped baffles 304 are provided inside the positioning hole 302. Specifically, torsion springs control the vertical rod 303 and the arc-shaped baffles 304, so that in the initial state, the arc-shaped baffles 304 are elastically ejected outwards, extending into the positioning hole 302. When the outrigger body 6 is pressed down on the bearing seat 2, the arc-shaped baffles 304 eject and lock onto the upper surface of the outrigger body 6 (e.g., ...). Figure 6As shown in the figure, the positioning top seat 301 locks and fixes the bridge crane outrigger body 6. When the bridge crane outrigger body 6 needs to be moved to the next construction site, the bridge crane only needs to control the bridge crane outrigger body 6 to lift it, which will drive the load-bearing seat 2 and the support pad 1 to be lifted synchronously and moved to the next construction site. There is no need for workers to manually carry and install it, which further improves work efficiency and does not affect the original structure of the load-bearing seat 2 and the support pad 1. While ensuring the stability of the support, it also improves the convenience of operation.

[0070] The upper end of the positioning top seat 301 is provided with an annular groove, and a drive ring 306 is rotatably connected in the annular groove. The upper end of the vertical rod 303 extends into the annular groove, and a limiting block 307 is fixedly connected to the upper end of the vertical rod 303. One end of the limiting block 307 is provided with an arc joint surface 308. The lower end of the drive ring 306 is provided with a limiting groove, and the limiting groove is adapted to the limiting block 307.

[0071] The limiting groove includes a receiving circular groove 5, the diameter of which is equal to that of the limiting circular block 307;

[0072] The limiting groove also includes a long arc groove, which includes a long arc edge 501 that communicates with the receiving circular groove 5. The curvature of the long arc edge 501 is adapted to the arc joint surface 308.

[0073] Preferably, when the bridge crane outrigger body 6 is released from its latch, it is necessary to control the four side arc-shaped baffles 304 to retract into the rotating cavity. To improve operational convenience, a drive ring 306 is provided. Specifically, a limit groove is provided at the lower end of the drive ring 306, and the limit groove is adapted to the limit block 307 (e.g., Figure 7 As shown), when the limiting block 307 is in the receiving groove 5, the limiting block 307 loses its restriction. Under the reset action of the torsion spring, the limiting block 307, the vertical rod 303 and the arc-shaped baffle 304 rotate. The arc-shaped baffle 304 extends out of the rotating cavity and engages with the bridge crane outrigger body 6.

[0074] When the arc-shaped baffle 304 needs to be retracted and reset, the driving ring 306 is rotated, and the limiting groove moves accordingly. When the intersection of the receiving circular groove 5 and the long arc edge 501 contacts the arc contact surface 308, the limiting block 307 can be pushed to rotate until the arc contact surface 308 is completely in contact with the long arc edge 501. At this time, the long arc edge 501 can limit the limiting block 307, and the arc-shaped baffle 304 retracts into the rotating cavity. The bridge crane outrigger body 6 can then be lifted, releasing the jamming state between the two. When re-jamming is required, the driving ring 306 is rotated in the opposite direction, so that the limiting block 307 returns to the receiving circular groove 5, and the arc-shaped baffle 304 pops out again. The operation is simple and convenient, and the four arc-shaped baffles 304 can be controlled simultaneously, making it highly practical.

[0075] Optionally, an annular tooth is provided on the outer side of the drive ring 306 and meshes with a gear 7. The lower end of the gear 7 is fixedly connected to a transmission rod 8. The transmission rod 8 is rotatably connected to the U-shaped frame 4. The lower end of the transmission rod 8 is fixedly connected to a cam 801. The upper end of the L-shaped positioning plate 402 is rotatably connected to a moving wheel 9. The moving wheel 9 and the cam 801 contact and roll with each other. A pair of cams 801 on the lower side of both ends of the U-shaped frame 4 are centrally symmetrically arranged.

[0076] When the operator rotates the drive ring 306, thereby driving the four-sided arc-shaped baffles 304 to retract into the rotating cavity, the drive ring 306 also drives the four-sided gears 7 to rotate through meshing connection, thereby driving the cam component 801 to rotate and pushing the driving wheel 9 to move the L-shaped positioning plate 402 outward. The pair of cam components 801, which rotate in the same direction but are centrally symmetrical, can simultaneously push the pair of L-shaped positioning plates 402 outward and unfold. Then, through the guide rod 407 and the inclined groove 406, the collection clamping plate 405 is also driven to move outward. That is to say, by rotating the drive ring 306, the clamping of the bridge machine outrigger body 6 is released, and the fixing between the alignment mechanism 3 and the bearing seat 2 and the support pad 1 is also released. The disassembly of this device can be completed directly in one go, which is highly practical. In addition, it also facilitates the drive control of the L-shaped positioning plates 402 and the collection clamping plate 405 on both sides during installation. No manual pulling is required, and the operation is convenient.
