Description

Technical Field

[0001] The present invention relates to the technical field of road and bridge construction, and in particular to a bridge construction support platform. Background Art

[0002] During bridge construction, since the bottom is in an elevated state, a support device needs to be installed underneath to withstand the pressure on the bridge to prevent the bridge from breaking due to excessive load. The support platforms currently used are mostly built manually through scaffolding, although they can support the bottom of the bridge during the construction process.

[0003] An improved approach is to use an adjustable support platform. This platform can be adjusted in height with a simple operation such as turning a handle, effectively supporting the bottom of the bridge. The platform also maintains stability by contacting the ground with support columns under the base. However, due to the uneven terrain and varying geological conditions at construction sites, including soft soil and rock foundations, adjusting the level of the base plate through the first support column is difficult. This can lead to uneven forces during bridge construction, compromising the stability and safety of the bridge structure. Therefore, adjusting the floor level is difficult. Summary of the Invention

It should be noted that, unless there is a conflict, the embodiments of the present disclosure and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] See Figures 1 to 4The bridge construction support platform of the embodiment of the present invention includes: a base 1, a lifting device 2 and an adjusting mechanism 3; wherein the lifting device 2 is arranged above the base 1 in the vertical direction, and a lifting plate 207 that can move in the vertical direction is arranged on the top of the lifting device 207; the adjusting mechanism 3 includes a rotating frame 304 and a supporting assembly, and the rotating frame 304 is vertically arranged on the top of the lifting plate 207 and is rotatably connected to the lifting plate 207; the supporting assembly is arranged on the top of the rotating frame 304, which includes a rotating plate 308, and the rotating plate 308 is rotatably connected to the rotating frame 304, and the rotating plane of the rotating plate 308 is set at a preset angle to the rotating plane of the rotating frame 304, so as to support the bottom surfaces of bridges of different shapes.

[0019] Specifically, the base 1 can be a square frame structure with an open top. The bottom of the lifting mechanism is connected to the inner wall of the base 1. One or more level detectors 204 are fixed to the outer surface of the base 1. The outer surface of the base 1 is fixedly connected to the outer surface of the control panel 205, which is electrically connected to the outer surface of the level detector 204 via wires. The lower surface of the base 1 is fixedly connected to multiple sets of universal wheels 206.

[0020] In this embodiment, the present invention may further include: a plurality of lifting components 4; wherein each of the lifting components 4 is arranged on the side wall of the base 1 to adjust the displacement of the base 1 in the vertical direction.

[0021] Specifically, the lifting assembly 4 includes a fixed base 402 and a first electric telescopic rod 401 connected to each other. The fixed base 402 is connected to the side wall of the base 1, and the first electric telescopic rod 401 is vertically inserted into the fixed base 402. A pad 403 is provided below the fixed base 402, and the output end of the first electric telescopic rod 401 is connected to the pad 403. The outer surface of the control panel 205 is electrically connected to the outer surfaces of the multiple groups of first electric telescopic rods 401 via wires.

[0022] In this embodiment, the coordinated operation of the level meter 204 and the first electric telescopic rod 401 allows for rapid and precise detection and adjustment of the levelness of the base 1. Based on the data provided by the level meter 204, construction workers can precisely control the extension and retraction of the first electric telescopic rod 401 via the control panel 205 to adjust the base 1 to a horizontal position. This provides a stable foundation for the entire support platform, ensuring that the platform will not tilt or shake due to uneven ground during bridge construction, ensuring the stability and safety of construction operations and laying a solid and reliable foundation for subsequent construction.

[0023] In this embodiment, the lifting device 2 includes: a lifting frame 208 and a lifting plate 207; wherein, the bottom of the lifting frame 208 is connected to the upper surface of the base 1; and the top of the lifting frame 208 is connected to the lower surface of the lifting plate 207.

[0024] Specifically, the lifting frame 208 can be a scissor-type telescopic frame, the bottom of the lifting frame 208 is fixedly connected to the inner wall of the base 1, and the top is connected to the lifting plate 207. The lifting plate 207 can be a square plate structure, and a connection hole can be opened in the middle, which is connected to the rotating frame 304 through a bearing.

[0025] In this embodiment, the support assembly includes: a support plate 303 and rotating plates 308 on both sides; wherein the rotating plates 308 on both sides are movably connected to the support plate 303 respectively; a second electric telescopic rod 305 is respectively provided under the two rotating plates 308, one end of the second electric telescopic rod 305 is connected to the rotating frame 304, and the other end is connected to the rotating plate 308 through the connecting seat 306 on the lower surface of the rotating plate 308, which is used to drive the rotating plate 308 to rotate to fit the shape of the bottom surface of the bridge.

[0026] Specifically, the support plate 303 in the middle and the rotating plates 308 on both sides may be connected via a rotating shaft.

[0027] The lower surface of the rotating plate 308 is fixedly connected to the connecting seat 306 , and the outer surface of the rotating frame 304 is rotatably connected to the second electric telescopic rod 305 , and the output end of the second electric telescopic rod 305 is hinged to the outer surface of the connecting seat 306 .

[0028] The rotating frame 304 may include: a cylindrical shell and a support frame placed therein. Openings may be provided on both sides of the cylindrical shell so that the rotating frame 304 is connected to the rotating plate 308 through the second electric telescopic rod 305, thereby adjusting the rotation angle of the rotating plate 308 relative to the rotating frame 304.

[0029] More specifically, one end of the second electric telescopic rod 305 can be connected to the support frame, and the other end extends out of the opening and connects to the connecting base 306, thereby driving the connecting base 306 to move. The connecting base 306 can be a pivot structure, with one end fixedly connected to the lower surface of the rotating plate 308 and the other end connected to the output end of the second electric telescopic rod 305 via a pivot. When the second electric telescopic rod 305 is extended or retracted, the output end of the second electric telescopic rod 305 guides the rotating plate 308 to rotate about the pivot center via the pivot. The angle of rotation can be determined based on the shape of the bottom surface of the bridge to be supported.

[0030] During implementation, the second electric telescopic rod 305 is activated, pushing the piston rod at the output end to extend or retract, thereby driving the corresponding movement of the connecting base 306. The movement of the connecting base 306 causes the rotating plate 308 to rotate on the outer surface of the support plate 303, with its connection point with the support plate 303 as the axis. As the rotating plate 308 rotates, its contact pattern and contact area with the lower surface of the bridge change. By continuously adjusting the stroke of the second electric telescopic rod 305, the rotating plate 308 can be made to closely conform to the shape and contour of the lower surface of the bridge, maximizing the contact area between the support plate 303 and the lower surface of the bridge, thereby improving the stability and reliability of the support.

[0031] The adjusting mechanism 3 also includes: a rotating motor 3011, a worm gear 307 and a worm 301; wherein, the worm gear 307 and the worm 301 are arranged on the lifting plate 207 at a position on one side of the rotating frame 304; the first end of the worm gear 307 is connected to the outer surface of the rotating frame 304, and the first end of the worm 301 is meshed with the worm gear 307. The rotating motor is arranged at one end of the worm 301, and its output shaft is connected to the worm 301, driving the worm 301 to drive the worm gear and the rotating frame 304 fixed thereto to rotate.

[0032] During specific implementation, the worm gear 307 is coaxially fixed to the cylindrical housing of the rotating frame 304, for example, it can be rigidly connected by a keyway or welding. The worm 301 can be fixed to the motor mounting seat on the side of the lifting plate 207, directly driven by the rotating motor, and can rotate forward and reverse. By adjusting the second electric telescopic rod 305 and the rotating motor, the support plate 303 is given a high degree of flexibility. The second electric telescopic rod 305 can drive the rotating plate 308 to rotate, increase the contact area between the support plate 303 and the lower surface of the bridge, and make the support more stable and reliable. The rotating motor drives the worm gear to rotate by driving the worm 301, and then drives the rotating frame 304 to rotate, so as to flexibly adjust the angle of the support plate 303. This design enables the support plate 303 to better adapt to the bottom surface of bridges of different shapes and structures, achieves a tightly fitting support, improves the adaptability of the support platform to various bridge construction scenarios, and effectively meets diverse construction needs.

[0033] Preferably, a fixing block is further provided on the upper surface of the lifting plate 207, and the fixing block is rotatably connected to the second end of the worm 301. The fixing block is fixedly connected to the upper surface of the lifting plate 207. The fixing block can be an inverted U-shaped block structure with an axial hole formed therein for connection with the worm 301.

[0034] It can be obviously concluded from the above that the bridge construction support platform provided in this embodiment can move the lifting plate in the vertical direction through the lifting device, so as to adjust the height of the entire support platform to adapt to bridge structures of different heights; and the rotating plate is rotatably connected to the rotating frame, and its rotating plane is set at a preset angle to the rotating plane of the rotating frame, so that the support assembly can be set at different inclination angles to support bridge bottom surfaces of different shapes, and the rotating frame is rotatably connected to the lifting plate, so that the support assembly can rotate vertically to better adapt to the special structure or construction requirements of the bridge bottom surface; further, the support platform can better adapt to bridge bottom surfaces of different shapes, ensuring that stable, reliable and high-fitting support is provided to the bridge structure during the bridge construction process.

[0035] Continue reading Figure 3 In the above embodiments, a limit block 309 is provided at the lower end of the rotating frame 304 passing through one end of the lifting plate 207 .

[0036] Specifically, the stopper 309 is fixed to the lower end of the rotating frame 304 and extends through the lower surface of the lifting plate 207. It is directly welded or bolted to the rotating frame 304 and, after passing through the lifting plate 207, can be positioned by a slot or thread. This limits the vertical movement of the rotating frame 304 on the lifting plate 207, preventing it from excessively descending or detaching, while also ensuring that the rotating frame 304 maintains vertical stability during rotation or elevation.

[0037] Furthermore, a limit ring 310 is provided on the outer surface of the rotating frame 304. The outer surface of the limit ring 310 is rotatably connected to the upper surface of the lifting plate 207, allowing the rotating frame 304 to rotate about its axis while limiting its horizontal displacement. Specifically, the inner ring of the limit ring 310 is connected to the cylindrical housing of the rotating frame 304 via a bearing, while the outer ring of the limit ring 310 is connected to the lifting plate 207 via another bearing, allowing the limit ring 310 to rotate around the lifting plate 207. The limit ring 310 is fixed to the outer surface of the rotating frame 304 and rotatably connected to the upper surface of the lifting plate 207 via a bearing or a bushing. This allows the rotating frame 304 to rotate about its axis while limiting its lateral displacement. This constrains the horizontal displacement of the rotating frame 304, preventing deviation during rotation. Through its rotatable connection with the lifting plate 207, the limit ring 310 shares the load of the rotating frame 304, ensuring smooth rotation.

[0038] In this embodiment, the limiting block 309 and the limiting ring 310 form a double upper and lower constraint to ensure that the rotating frame 304 can only rotate and rise and fall within the designed range.

[0039] In this embodiment, the input motion of the worm 301 is converted into the rotation of the rotating frame 304 by the worm gear; the limiting ring 310 ensures the stable engagement of the worm gear and the worm through radial support and axial limitation, while constraining the freedom of the rotating frame 304.

[0040] The working principle of the embodiment of the present invention is as follows: During the initial preparation phase of bridge construction, the entire device is first moved to a predetermined location near the bridge construction site using the multiple sets of universal wheels 206 on the lower surface of the base 1. After reaching the approximate location, the construction personnel activate the level meter 204 by operating the control panel 205. The level meter 204 quickly detects the initial horizontal state of the base 1 and transmits the detection data to the control panel 205 in real time. Based on the data fed back by the level meter 204, if the base 1 is found to be uneven, the construction personnel activate the first electric telescopic rod 401 at the corresponding position through the control panel 205. After the first electric telescopic rod 401 receives the electrical signal, the motor inside it drives the telescopic rod to extend, and the output end drives the pad 403 to slowly move downward. Because the pad 403 is in contact with the ground, as the pad 403 descends, the pad 403 exerts pressure on the ground, thereby lifting the corresponding corner of the base 1 upward. During this process, the construction workers continuously pay attention to the changes in the data of the level detector 204 displayed on the control panel 205, and accurately adjust the extension and retraction amount of each first electric telescopic rod 201 until the level detector 204 shows that the base 1 is in a horizontal state, ensuring that the foundation of the entire device is stable and providing a stable support platform for subsequent construction operations.

[0041] After the base 1 is adjusted horizontally, the construction personnel start the lifting device 2 through the control panel 205. The lifting device 2 drives the internal mechanical structure to operate according to the preset program or the instructions manually input by the construction personnel, driving the lifting plate 207 to rise or fall smoothly. During the lifting process, the height position of the lifting plate 207 can be accurately controlled according to the actual height requirements of the bridge, so that the adjustment mechanism 3 on the lifting plate 207 can accurately dock with the bottom surface of the bridge and perform subsequent operations. After the lifting plate 207 reaches the appropriate height, the second electric telescopic rod 305 is started. The motor of the second electric telescopic rod 305 is started, pushing the piston rod at the output end to extend or retract, thereby driving the connecting seat 306 to move accordingly. The movement of the connecting seat 306 causes the rotating plate 308 to rotate on the outer surface of the support plate 303 with its connection point with the support plate 303 as the axis. As the rotating plate 308 rotates, its contact mode and contact area with the lower surface of the bridge change. By continuously adjusting the stroke of the second electric telescopic rod 305, the rotating plate 308 can be made to fit closely to the shape and contour of the lower surface of the bridge, thereby maximizing the contact area between the support plate 303 and the lower surface of the bridge and improving the stability and reliability of the support.

[0042] When it is necessary to adjust the angle of the support plate 303 to better adapt to the special structure or construction requirements of the bottom surface of the bridge, start the rotating motor connected to the worm 301. The rotating motor drives the worm 301 to rotate. Since the worm 301 is engaged with the worm wheel 307 on the rotating frame 304, the rotation of the worm 301 will drive the worm wheel 307 to rotate synchronously. The rotation of the worm wheel 307 drives the rotating frame 304 fixedly connected thereto to rotate around its connection point with the lifting plate 207. During the rotation process, construction personnel can stop or adjust the operation of the rotating motor at any time according to actual conditions, accurately control the rotation angle of the rotating frame 304, and thus achieve flexible adjustment of the angle of the support plate 303, so that it can better adapt to the different shapes of the bottom surface of the bridge, ensuring that stable, reliable and high-fitting support is provided to the bridge structure during the bridge construction process.

[0043] In summary, the present invention has the following beneficial effects: 1. The level meter and the first electric telescopic rod work together to quickly and accurately check and adjust the base's level. Based on the level meter's feedback, construction workers can precisely control the extension and retraction of the first electric telescopic rod via the control panel to adjust the base to a horizontal position. This provides a stable foundation for the entire support platform, ensuring that the platform will not tilt or shake due to uneven ground during bridge construction. This ensures the stability and safety of construction operations and lays a solid and reliable foundation for subsequent construction.

[0044] 2. The support plate is highly flexible thanks to the second electric telescopic rod and rotating motor in the adjustment mechanism. The second electric telescopic rod drives the rotating plate, increasing the contact area between the support plate and the bridge's underside, ensuring more stable and reliable support. The rotating motor drives the rotating frame via a worm gear drive, allowing for flexible adjustment of the support plate's angle. This design allows the support plate to better adapt to bridge undersides of varying shapes and structures, achieving a tightly fitting support. This enhances the platform's adaptability to various bridge construction scenarios and effectively meets diverse construction needs.

[0045] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
