Description

[0002] In bridge reinforcement and maintenance projects, the construction of the bridge bottom construction platform is a key technical link. Traditional construction mostly uses full-bridge brackets or segmented suspension platforms, which have the problem of repeated disassembly and assembly and low mobility efficiency. Especially when crossing bridge piers, the existing integral platform is often forced to be disassembled and reassembled due to structural interference, which prolongs the construction period and significantly increases the risk of high-altitude operations.

[0003] The reinforced platform at the bottom of the bridge serves as the main support surface for construction workers. It has a large area and stable support functions. Therefore, its structural stability determines its own large weight and volume. When crossing the bridge piers, obstacle avoidance and center of gravity control of the supporting surface are very important. Direct dismantling and reorganization not only wastes time, but also increases the risk of high-altitude operations. During the movement and obstacle avoidance of the entire platform, the offset of the center of gravity of the platform will make the suspension of the entire platform unstable, resulting in deformation and damage to the suspension structure.

DETAILED DESCRIPTION

[0024] The present invention discloses a jacking reinforcement platform, such as Figure 1 As shown, it includes a main walking frame body 1 and an auxiliary walking frame body 2 that move along the bridge deck, and platform support parts 11 are suspended downward at both ends of the main walking frame body 1, and the platform support part 11 includes a supporting chassis 111, and the supporting chassis 111 is a disc-shaped structure. The edge of the supporting chassis 111 is provided with a circular slide rail 112, and a supporting platform 12 is slidably provided on the slide rail 112. The free ends of the two supporting platforms 12 are butt-jointed under the bridge to form a construction platform located on the bottom side of the bridge; refer to Figure 3 The support platform 12 includes a plurality of spliced ​​long boards 121, and the ends of the long boards 121 are slidably set on the slide rails 112. Auxiliary support parts 21 are suspended downward at both ends of the auxiliary walking frame 2, and the auxiliary support parts 21 include support beams 211. The long boards 121 move along the support chassis 111 so that the free ends of the long boards 121 are supported by the support beams 211.

[0025] This jacking reinforcement platform is used to be erected on the bridge deck, and the construction platform is suspended on the bottom side of the bridge. It can move along the extension direction of the bridge without dismantling the overall structure; Figure 1 and Figure 2During normal construction, the two support platforms 12 are connected to each other to form a platform structure across the bottom side of the bridge for construction workers to walk and construct. As the main walking frame 1 moves, the platform moves on the bottom side of the bridge. When it is necessary to cross the pier, the support platform 12 is rotated along the slide rail 112 on the support chassis 111. The support platform 12 is divided into a plurality of long strips 121, which are rotated 90° in sections and supported by the support beams 211 on the auxiliary walking frame 2. When all the long strips 121 are rotated 90° and supported by the support beams 211, the main walking frame 1 is moved to drive the entire support platform 12 to cross the pier from the edge of the bridge. After crossing the pier, the long strips 121 are rotated again to make the long strips The plate 121 is returned to its position, and the two support platforms 12 are connected to form an under-bridge platform for construction workers to walk and construct. This structure divides the platform into two sections, which are rotated away from the obstruction of the bridge piers. Without dismantling the overall structure, the movement of the entire reinforced platform in the direction of the bridge is ensured. By setting up a secondary walking frame 2, the rotating free end of the support platform 12 is supported to prevent the support platform 12 from falling. Furthermore, the support platform 12 is set as a number of long plates 121, which are rotated to the position of the support beam 211 in batches. This structure can gradually shift the center of gravity of the support platform 12 to prevent the support platform 12 from bending downward due to excessive center of gravity deviation when the support platform 12 rotates freely.

[0026] In a further solution, Figure 3 As shown, a plurality of rotating rings 113 are coaxially rotatably provided on the lower side of the support chassis 111, and the plurality of rotating rings 113 are respectively fixedly connected to the plurality of long strips 121. A baffle plate 114 is also fixedly provided on the lower side of the support chassis 111, and a plurality of motors 115 are provided on the baffle plate 114. The plurality of motors 115 respectively drive each of the rotating rings 113 to rotate through gears.

[0027] In this structure, each long board 121 is driven by a motor 115 to achieve independent movement and positioning. The coaxially arranged rotating ring 113 can ensure that the moving path of each long board 121 is the same, thereby achieving smooth rotation.

[0028] In a further solution, Figure 1 and Figure 2 As shown, the auxiliary walking frame 2 also includes an upper beam 212, on which a telescopic cylinder 213 is fixedly provided. A support rod 214 extends upward from the end of the support beam 211, and the support rod 214 is slidably arranged at the end of the upper beam 212. The telescopic cylinder 213 drives the support rod 214 to move vertically.

[0029] This structure drives the support beam 211 to move up and down through the telescopic cylinder 213 to achieve height adjustment of the support beam 211. Support wheels of different heights achieve different supporting effects. When the support platform 12 is moved across the bridge, the support beam 211 is used to support the free end of the long board 121. When the support platform 12 is spliced, the auxiliary walking frame 2 is moved, and the support beam 211 can be supported on the bottom side of the baffle 114 to further provide support for the support platform 12.

[0030] In a further solution, Figure 1 and Figure 2 As shown, the main walking frame 1 includes two main moving seats 13, and the main moving seat 13 includes a main moving vehicle 131. The top of the main moving vehicle 131 is provided with a first vertical column 132, and the top of the first vertical column 132 is provided with a first top seat 133. The first top seat 133 extends downwardly and is provided with a first vertical rod 134. The end of the first vertical rod 134 is fixedly connected to the supporting chassis 111. The first vertical rod 134 is movably provided with a first side stopper 135, and the first side stopper 135 is rotatably provided with a stopper wheel that rolls along the outer side of the bridge; a synchronization rod 15 is connected between the two first top seats 133, and the synchronization rod 15 includes a middle tube 151, and the two ends of the middle tube 151 are respectively threadedly connected with side tubes 152, and the threads of the two side tubes 152 are opposite, and the side tubes 152 are respectively fixedly connected to the first top seats 133.

[0031] In this structure, the relative distance between the two first top seats 133 is determined by adjusting the length of the synchronization rod 15. Under the support of the first vertical column 132, above the railings on both sides of the bridge, the two first side blocks 135 are placed on both sides of the bridge to limit the lateral position of the main traveling frame 1. Driven by the main moving vehicle 131, the entire main traveling frame 1 is ensured to move along the extension direction of the bridge. The synchronization rod 15 serves as a connecting piece of the two first top seats 133, and its length can be adjusted to adapt to bridges of different widths. It can also synchronize the movement of the suspension structures on both sides to achieve stable translation of the platform under the bridge.

[0032] In a further solution, Figure 1 and Figure 2 As shown, the auxiliary walking frame 2 includes two auxiliary moving seats 22, and the auxiliary moving seat 22 includes an auxiliary moving vehicle 221. A second vertical column 222 is provided on the top of the auxiliary moving vehicle 221, and a second top seat 223 is provided on the top of the second vertical column 222. The second top seat 223 extends downwardly and is provided with a second vertical rod 224. The second vertical rod 224 is movably provided with a second side block 225, and the second side block 225 is rotatably provided with a block wheel that rolls along the outer side of the bridge; the second side block 225 is fixedly connected to the upper beam 212, and a guide rod 14 is fixedly provided on the first top seat 133, and the second top seat 223 is slidably set on the guide rod 14.

[0033] In this structure, the second top seat 223 is supported by the second vertical column 222 and is located above the railings on both sides of the bridge. The moving direction of the second top seat 223 is determined by the guide rod 14 to ensure the movement and adjustment of the entire auxiliary traveling frame 2. With the support of the second side block 225, the auxiliary traveling frame 2 moves stably without shaking and can move stably with the entire equipment.

[0034] In a further solution, Figure 4 As shown, a stop block 1211 is provided on the lower side of the free end of the long board 121 , and when the long board 121 is supported by the support beam 211 and the main walking frame 1 drives the platform support part 11 to move, the stop block 1211 is blocked on the outside of the support beam 211 .

[0035] Under the contact of the stopper 1211, the main traveling frame 1 can drive the entire auxiliary traveling frame 2 to move, that is, there is no need to set a driving device on the auxiliary traveling frame 2, and it is only driven by the main moving vehicle 131, saving the investment in the electric drive structure.

[0036] In a further solution, Figure 4 and Figure 5 As shown, the contact surfaces of two adjacent long strips 121 are respectively provided with an embedding platform and an embedding groove.

[0037] By providing the embedded platform and the embedded groove, the long strips 121 that are spliced ​​and butted together can support each other to form a stable support platform 12.

[0038] In a further solution, Figure 1 , Figure 2 and Figure 3 As shown, the support chassis 111 is also provided with a pushing portion 116, and a synchronous member 117 is fixedly provided at the end of the pushing portion 116. A plurality of latches 118 are fixedly provided on the synchronous member 117. A pin hole 1212 is provided at the end of the long strip 121. After the support platform 12 is docked, the pushing portion 116 drives the latch 118 to be inserted into the pin hole 1212 to fix the plurality of long strips 121.

[0039] When the support platform 12 is docked, the pushing part 116 pushes the synchronous part 117, inserts a plurality of pins 118 into the pin holes 1212 of the long boards 121, fixes a plurality of long boards 121 arranged side by side, and avoids the long boards 121 being relatively far away from each other; when the long boards 121 rotate respectively, the pushing part 116 retracts the synchronous part 117, and the long boards 121 can rotate sequentially.

[0040] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
