Description

Technical Field

[0001] This utility model relates to the field of bridge construction, specifically to an adaptive support platform for bridge construction. Background Technology

[0002] Currently, with the continuous advancement of urbanization, bridges, as an important infrastructure, have also experienced rapid development. However, in actual construction, due to the large spans of bridges and the complex and varied terrain, ensuring the safety of construction workers has become a challenge. While traditional temporary support frames can meet the needs to some extent, they prove inadequate when facing steep slopes or rapid water flows.

[0003] Existing solutions mainly include building working platforms by erecting steel pipe scaffolding and using hydraulic lifts. The former is inexpensive but lacks flexibility and is not easy to adjust in height; the latter, although it can be flexibly adjusted in height, is inconvenient to carry for field construction and is easily restricted by the site. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adaptive support platform for bridge construction that is easy to carry, quick to connect and assemble, and can flexibly adjust the height of the support plate according to actual use needs, and has good support stability, in light of the current state of the technology.

[0005] This utility model is achieved through the following technical solution: This utility model proposes an adaptive support platform for bridge construction, including a support plate. An electric telescopic outrigger is provided at each of the four corners of the bottom end of the support plate. A retraction mechanism is installed between each electric telescopic outrigger and the support plate. Each electric telescopic outrigger includes a sleeve rod, a drive motor installed at the top of the sleeve rod, a screw installed at the power output end of the drive motor, a telescopic rod installed on the outside of the screw rod, and a foot installed at the bottom of the telescopic rod. The retraction mechanism includes a rotating frame installed at the four corners of the bottom end of the support plate, a turntable installed within the rotating frame, and an electric telescopic rod installed between the outer wall of the sleeve rod and the bottom end of the support plate. Two connecting slots are symmetrically opened on one side wall of the support plate. Two connecting blocks with their own slots are symmetrically installed on the side of the support plate opposite to the connecting slots. A locking mechanism is also installed on the support plate between the two connecting slots.

[0006] By adopting the above technical solution, when setting up a support platform at a bridge construction site, the folded support plate is first moved to the support platform setup position, and the electric telescopic outriggers are extended under the action of the electric telescopic rod. Then, the drive motor is started to rotate the screw. After the screw rotates, it moves down along the sleeve rod under the action of threaded transmission, thereby realizing the height adjustment of the support plate as needed, ensuring stable contact between the bottom of the support plate and the ground of the bridge construction site, and realizing the rapid placement of the support plate. After one support plate is placed stably, the connecting block of the other support plate is inserted into the connecting groove of the first placed plate, and the locking mechanism is used to realize the rapid insertion and limiting between the connecting block and the connecting groove, thereby ensuring the rapid connection and construction of the support platform.

[0007] Furthermore, the locking mechanism includes a groove formed on the support plate between the two connecting grooves, a dual-axis motor installed in the groove, a lead screw installed on the two power output ends of the dual-axis motor, and a limiting rod installed on the lead screw.

[0008] By adopting the above technical solution, the dual-axis motor drives the lead screw to rotate, which causes the limiting rod to slide into the slot in the connecting block, so that the connecting block and the connecting slot can be quickly inserted and limited after the limiting rod is inserted into the slot.

[0009] Furthermore, the limiting rod is a square rod structure, and the support plate has a hollow square structure located at the limiting rod, with the limiting rod slidingly engaged with the support plate.

[0010] By adopting the above technical solution, the rapid sliding adjustment of the limiting rod relative to the support plate can be ensured.

[0011] Furthermore, the slot is formed on the connecting block, and the slot has a square groove structure, and the size of the limiting rod matches the size of the slot.

[0012] By adopting the above technical solution, it can be ensured that the limiting rod can be easily inserted into the slot after the connecting groove contacts the corresponding connecting block.

[0013] Furthermore, the support plate is an aluminum alloy plate, a support rod is installed on one side of the top of the support plate, an operation panel is installed on the top of the support rod, and a storage battery is installed in the middle of the bottom of the support plate.

[0014] By adopting the above technical solution, the battery can ensure the normal power supply and operation of the drive motor, the dual-axis motor, and the electric telescopic rod.

[0015] Furthermore, the operation panel is electrically connected to the drive motor, the dual-axis motor, and the electric telescopic rod.

[0016] By adopting the above technical solution, the operation panel can control the circuit to open and close the drive motor, the dual-axis motor and the electric telescopic rod as needed, so as to achieve flexible support and placement of the support plate.

[0017] Furthermore, the turntable is welded to the top of the sleeve rod, the turntable is rotatably connected to the short shaft on the rotating frame, and the electric telescopic rod is hinged to the support plate and the sleeve rod.

[0018] By adopting the above technical solution, when the electric telescopic outrigger is not in use, the electric telescopic rod can be used to conveniently retract the electric telescopic outrigger to the bottom of the support plate, so as to realize the convenient carrying and use of the support plate.

[0019] Furthermore, the screw is threadedly connected to the telescopic rod, the telescopic rod is a square rod, the telescopic rod is slidably engaged with the sleeve rod, and the support leg is composed of a square plate and a support column welded to the lower side of the square plate. The support leg is welded to the telescopic rod.

[0020] By adopting the above technical solution, the screw will rotate and cause the telescopic rod to move down along the sleeve rod, so that the support plate can be stably supported at the construction position after the bottom end of the support rod is inserted into the ground.

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] This invention features an electrically operated telescopic outrigger, consisting of a drive motor, a sleeve rod, a screw rod, a telescopic rod, and outrigger feet, installed at each of the four corners of the bottom of a support plate. A retraction mechanism is installed between each of the electric telescopic outriggers and the support plate. This allows the support platform to be quickly transported to the bridge construction site. The electric telescopic rod in the retraction mechanism quickly extends the electric telescopic outriggers, and the drive motor and screw rod move the telescopic rod down along the sleeve rod, allowing the outrigger feet at the bottom of the electric telescopic outriggers to quickly insert into contact with the ground. This ensures flexible height adjustment of the support plate while enabling rapid placement and support at the bridge construction site. Furthermore, the connecting grooves, connecting blocks, and locking mechanisms on both sides of the support plate allow for quick connection and positioning of adjacent support plates after assembly, ensuring the rapid and efficient construction of the support platform.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] like Figures 1-3As shown, an adaptive support platform for bridge construction in this embodiment includes a support plate 7. An electric telescopic outrigger 3 is provided at each of the four corners of the bottom end of the support plate 7. A retraction mechanism 2 is installed between each electric telescopic outrigger 3 and the support plate 7. The electric telescopic outrigger 3 includes a sleeve rod 302, a drive motor 301 installed at the top of the sleeve rod 302, a screw 303 installed at the power output end of the drive motor 301, a telescopic rod 304 installed on the outside of the screw 303, and a foot 305 installed at the bottom of the telescopic rod 304. The retraction mechanism 2 includes a rotating frame 202 installed at the four corners of the bottom end of the support plate 7, a turntable 201 installed in the rotating frame 202, and an electric telescopic rod 203 installed between the outer wall of the sleeve rod 302 and the bottom end of the support plate 7. Two connecting slots 1 are symmetrically opened on one side wall of the support plate 7. Two connecting blocks 6 with their own slots 5 are symmetrically installed on the side of the support plate 7 opposite to the connecting slots 1. A locking mechanism 10 is also installed on the support plate 7 between the two connecting slots 1.

[0032] This utility model provides an adaptive support platform for bridge construction that is easy to carry, quick to assemble, and allows for flexible height adjustment of the support plate 7 according to actual needs, while also providing good support stability. This solves the problems of existing technologies that primarily rely on steel pipe scaffolding or hydraulic lifts to construct work platforms. The former is inexpensive but lacks flexibility and is difficult to adjust in height; the latter, while offering flexible height adjustment, is inconvenient to carry in field operations and is easily limited by site constraints. The overall approach of this utility model to solve these problems is to allow for quick and easy transport of the folded support plate 7. Upon reaching the bridge construction site, the electric telescopic outrigger 3 is quickly extended using the electric telescopic rod 203 in the retraction mechanism 2. The telescopic rod 304 is then moved downwards along the sleeve rod 302 using the drive motor 301 and screw 303, allowing the bottom foot 305 of the electric telescopic outrigger 3 to quickly insert into contact with the ground. This ensures flexible height adjustment of the support plate 7 while enabling rapid support and placement of the support plate 7 at the bridge construction site. Furthermore, the connecting grooves 1, connecting blocks 6, and locking mechanism 10 on both sides of the support plate 7 allow for rapid connection and positioning of adjacent support plates 7 after assembly, ensuring the rapid and efficient construction of the support platform.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the locking mechanism 10 includes a groove 1003 located between two connecting grooves 1 on the support plate 7, a dual-axis motor 1004 installed in the groove 1003, a lead screw 1002 installed on the two power output ends of the dual-axis motor 1004, and a limiting rod 1001 installed on the lead screw 1002.

[0034] In one implementation, the dual-axis motor 1004 drives the lead screw 1002 to rotate, which causes the limiting rod 1001 to slide into the slot 5 in the connecting block 6, so that the connecting block 6 and the connecting groove 1 can be quickly inserted and limited after the limiting rod 1001 is inserted into the slot 5.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the limiting rod 1001 is a square rod structure, and the support plate 7 has a hollow square structure located at the limiting rod 1001. The limiting rod 1001 and the support plate 7 are in sliding fit.

[0036] As one implementation method, it is possible to ensure rapid sliding adjustment of the limit rod 1001 relative to the support plate 7.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the slot 5 is formed on the connecting block 6, and the slot 5 is a square groove structure. The size of the limiting rod 1001 matches the size of the slot 5.

[0038] As one implementation method, it can be ensured that after the connecting groove 1 contacts the corresponding connecting block 6, the limiting rod 1001 can be easily inserted into the slot 5.

[0039] like Figure 1 As shown, in this embodiment, the support plate 7 is an aluminum alloy plate, a support rod 8 is installed on one side of the top of the support plate 7, an operation panel 9 is installed on the top of the support rod 8, and a storage battery 4 is also installed in the middle of the bottom of the support plate 7.

[0040] As one implementation method, the battery 4 can ensure the normal power supply and operation of the drive motor 301, the dual-axis motor 1004, and the electric telescopic rod 203.

[0041] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the operation panel 9 is electrically connected to the drive motor 301, the dual-axis motor 1004, and the electric telescopic rod 203.

[0042] As one implementation method, the operation panel 9 can be used to control the on / off state of the control circuit to enable the drive motor 301, the dual-axis motor 1004 and the electric telescopic rod 203 to be opened and closed as needed, so as to enable the support plate 7 to be flexibly supported and placed.

[0043] like Figure 1 As shown, in this embodiment, the turntable 201 is welded to the top of the sleeve rod 302, the turntable 201 is rotatably connected to the short shaft on the rotating frame 202, and the electric telescopic rod 203 is hinged to the support plate 7 and the sleeve rod 302.

[0044] As one implementation method, when the electric telescopic outrigger 3 is not in use, the electric telescopic rod 203 can be used to conveniently retract the electric telescopic outrigger 3 to the bottom of the support plate 7, so as to make the support plate 7 easy to carry and use.

[0045] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the screw 303 is threadedly connected to the telescopic rod 304, the telescopic rod 304 is a square rod, the telescopic rod 304 is slidably engaged with the sleeve rod 302, and the support leg 305 is composed of a square plate and a support column welded to the lower side of the square plate. The support leg 305 is welded to the telescopic rod 304.

[0046] In one implementation, the rotation of the screw 303 causes the telescopic rod 304 to move down along the sleeve rod 302, so that the support plate 7 can be stably supported at the erection position after the bottom end of the support rod 8 is inserted into the ground.

[0047] The specific implementation process of this embodiment is as follows: When setting up a support platform at the bridge construction site, the folded support plate 7 is first moved to the support platform construction position, and the electric telescopic outrigger 3 is opened under the action of the electric telescopic rod 203. Then, the drive motor 301 is started to make the screw 303 rotate. After the screw 303 rotates, it will move down along the sleeve rod 302 under the action of thread transmission, thereby realizing the height of the support plate 7 as needed, ensuring that the bottom end of the support plate 7 is in stable contact with the ground of the bridge construction site, and realizing the rapid placement of the support plate 7. After one support plate 7 is placed stably, the connecting block 6 on the other support plate 7 is inserted into the connecting groove 1 on the first placed plate, and the screw 303 is driven to rotate by the dual-axis motor 1004 in the locking mechanism 10 to ensure that the limiting rod 1001 can be quickly inserted into the slot 5 in the connecting block 6, so as to realize the rapid insertion and limiting between the connecting block 6 and the connecting groove 1, thereby ensuring the rapid connection and construction of the support platform.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
