Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction technology, and more specifically, to a bridge construction support platform. Background Technology

[0002] During bridge construction, since the area underneath is elevated, support structures need to be installed to withstand the pressure on the bridge and prevent it from breaking due to excessive load. Currently, most support platforms are manually constructed using scaffolding, which can provide support to the bottom of the bridge during construction.

[0003] One improvement is to use an adjustable support platform. This platform can be adjusted in height through simple operations such as turning a handle, effectively supporting the bottom of the bridge and enhancing stability through the ground contact between the support columns under the base. However, due to the potentially uneven terrain and varying geological conditions at construction sites, such as soft soil foundations and rock foundations, adjusting the level of the base plate through the initial support is not convenient. If the base plate is not level, it will lead to uneven stress during bridge construction, thus affecting the stability and safety of the bridge structure. Therefore, there is a problem with the difficulty in adjusting the level of the base plate. Summary of the Invention

The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] See Figures 1 to 4 The bridge construction support platform of this utility model embodiment includes: a base 1, a lifting device 2, and an adjustment mechanism 3; wherein, the lifting device 2 is vertically arranged above the base 1, and a lifting plate 207 movable in the vertical direction is arranged on its top; the adjustment mechanism 3 includes a rotating frame 304 and a support assembly, the rotating frame 304 is vertically arranged on the top of the lifting plate 207 and rotatably connected to the lifting plate 207; the support assembly is arranged on the top of the rotating frame 304, and includes a rotating plate 308, the rotating plate 308 is rotatably connected to the rotating frame 304, and the rotation plane of the rotating plate 308 is set at a preset angle with the rotation plane of the rotating frame 304, so as to support the bridge bottom surface of different shapes.

[0033] Specifically, the base 1 can be a square frame structure with an opening at the top. The bottom of the lifting mechanism is connected to the inner wall of the base 1. One or more sets of level detectors 204 are fixed to the outer surface of the base 1. The outer surface of the base 1, to which the control panel 205 is fixedly connected, is electrically connected to the outer surface of the level detectors 204 via wires, and multiple sets of casters 206 are fixedly connected to the lower surface of the base 1.

[0034] In this embodiment, it may further include: a plurality of lifting components 4; wherein each of the lifting components 4 is disposed on the side wall of the base 1 for adjusting the displacement of the base 1 in the vertical direction.

[0035] Specifically, the lifting assembly 4 includes: a fixed base 402 and a first electric telescopic rod 401 connected to each other; wherein, the fixed base 402 is connected to the side wall of the base 1, and the first electric telescopic rod 401 is vertically inserted through 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 surface of multiple sets of first electric telescopic rods 401 via wires.

[0036] In this embodiment, the levelness of the base 1 can be quickly and accurately detected and adjusted by the coordinated operation of the leveling instrument 204 and the first electric telescopic rod 401. Based on the data fed back by the leveling instrument 204, construction personnel 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 level state. This provides a stable foundation for the entire support platform, ensuring that the platform will not tilt or sway due to uneven ground during bridge construction, guaranteeing the stability and safety of construction operations, and laying a solid and reliable foundation for subsequent construction.

[0037] 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.

[0038] 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 with a connection hole in the middle, and is connected to the rotating frame 304 through a bearing.

[0039] In this embodiment, the support assembly includes a support plate 303 and two 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 below 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, for driving the rotating plate 308 to rotate so as to conform to the shape of the bottom surface of the bridge.

[0040] Specifically, the support plate 303 in the middle and the rotating plates 308 on both sides can be connected by a rotating shaft.

[0041] The lower surface of the rotating plate 308 is fixedly connected to a connecting seat 306, and the outer surface of the rotating frame 304 is rotatably connected to a second electric telescopic rod 305, the output end of which is hinged to the outer surface of the connecting seat 306.

[0042] The rotating frame 304 may include a columnar outer shell and a support frame placed therein. Openings may be provided on both sides of the columnar outer shell so that the rotating frame 304 can be 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.

[0043] 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 seat 306, driving the connecting seat 306 to move. The connecting seat 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 performs telescopic movement, its output end can guide the rotating plate 308 to rotate around the pivot center through the pivot. The rotation angle can be determined according to the shape of the bottom surface of the bridge to be supported.

[0044] In practice, the second electric telescopic rod 305 is activated, pushing the piston rod at the output end to extend or retract, thereby causing 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 method 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, and improving the stability and reliability of the support.

[0045] The adjustment mechanism 3 further includes: a rotary motor 3011, a worm gear 307, and a worm 301; wherein, the worm gear 307 and the worm 301 are disposed 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, the first end of the worm 301 is meshed with the worm gear 307, the rotary motor is disposed 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.

[0046] In practice, the worm gear 307 is coaxially fixed to the cylindrical shell of the rotating frame 304, for example, through a rigid connection via keyway or welding. The worm 301 can be fixed to the motor mounting base on the side of the lifting plate 207 and is directly driven by the rotating motor, allowing for forward and reverse rotation. Adjusting the second electric telescopic rod 305 and the rotating motor provides the support plate 303 with a high degree of flexibility. The second electric telescopic rod 305 can drive the rotating plate 308 to rotate, increasing the contact area between the support plate 303 and the underside of the bridge, making the support more stable and reliable. The rotating motor drives the worm gear 301 to rotate, which in turn drives the rotating frame 304 to rotate, thereby flexibly adjusting the angle of the support plate 303. This design allows the support plate 303 to better adapt to bridge undersides of different shapes and structures, achieving close-fitting support, improving the adaptability of the support platform to various bridge construction scenarios, and effectively meeting diverse construction needs.

[0047] 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 gear 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, in which a shaft hole is provided for connection with the worm gear 301.

[0048] It is evident from the above that the bridge construction support platform provided in this embodiment can adjust the height of the entire support platform by vertically moving the lifting plate through the lifting device to adapt to bridge structures of different heights. The rotating plate and rotating frame are rotatably connected, and their rotation plane is set at a preset angle to the rotation plane of the rotating frame. This allows the support components to be set at different tilt angles to support bridge undersides of different shapes. The rotatable connection between the rotating frame and the lifting plate allows the support components to rotate vertically to better adapt to the special structure or construction requirements of the bridge underside. Furthermore, this enables the support platform to better adapt to bridge undersides of different shapes, ensuring stable, reliable, and highly conforming support for the bridge structure during bridge construction.

[0049] Continue reading Figure 3 In the above embodiments, a limit block 309 is provided at the lower end of the rotating frame 304 that passes through the lifting plate 207.

[0050] Specifically, the limiting block 309 is fixed to the lower end of the rotating frame 304 and passes 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, it can be limited by a slot or thread. It limits the vertical movement range of the rotating frame 304 on the lifting plate 207, preventing it from descending excessively or detaching, while ensuring that the rotating frame 304 maintains vertical stability during rotation or lifting.

[0051] Furthermore, a limiting ring 310 is provided on the outer surface of the rotating frame 304. The outer surface of the limiting ring 310 is rotatably connected to the upper surface of the lifting plate 207, thereby allowing the rotating frame 304 to rotate around its axial direction while restricting its horizontal displacement. Specifically, the inner ring of the limiting ring 310 can be connected to the cylindrical outer shell of the rotating frame 304 via a bearing, and the outer ring of the limiting ring 310 can be connected to the lifting plate 207 via another bearing, thereby allowing the limiting ring 310 to rotate around the lifting plate 207 as a whole. The limiting 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 bushing. It allows the rotating frame 304 to rotate around its axis while fixing the lateral displacement. It constrains the horizontal displacement of the rotating frame 304 to prevent deviation during rotation. Through the rotatable connection with the lifting plate 207, it shares the load of the rotating frame 304, ensuring smooth rotation.

[0052] In this embodiment, the limiting block 309 and the limiting ring 310 form a double constraint, ensuring that the rotating frame 304 can only rotate and rise within the design range.

[0053] 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 meshing of the worm gear and worm through radial support and axial limiting, while constraining the degree of freedom of the rotating frame 304.

[0054] The working principle of this utility model embodiment is as follows:

[0055] In the early preparation stage of bridge construction, the entire device is first moved to the vicinity of the predetermined position on the bridge construction site using multiple sets of universal wheels 206 on the lower surface of the base 1. After reaching the approximate position, the construction personnel activate the leveling instrument 204 through the control panel 205. The leveling instrument 204 quickly detects the initial levelness of the base 1 and transmits the detection data to the control panel 205 in real time. If the data fed back by the leveling instrument 204 indicates that the base 1 is not level, the construction personnel activate the first electric telescopic rod 401 at the corresponding position through the control panel 205. After receiving the electrical signal, the motor inside the first electric telescopic rod 401 drives the telescopic rod to extend, and the output end drives the pad 403 to move slowly downward. Since 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 personnel continuously monitor the changes in the data displayed on the level detector 204 on the control panel 205, and precisely adjust the extension and retraction 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.

[0056] After the base 1 is leveled, the construction personnel start the lifting device 2 via the control panel 205. The lifting device 2, according to a preset program or instructions manually input by the construction personnel, drives the internal mechanical structure to operate, causing the lifting plate 207 to rise or fall smoothly. During the lifting process, the height of the lifting plate 207 can be precisely controlled according to the actual height requirements of the bridge, allowing the adjustment mechanism 3 on the lifting plate 207 to accurately align with the bridge's underside and facilitate subsequent operations. After the lifting plate 207 reaches the appropriate height, the second electric telescopic rod 305 is activated. The motor of the second electric telescopic rod 305 starts, pushing the piston rod at the output end to extend or retract, thereby causing 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 method 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 fit 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, and improving the stability and reliability of the support.

[0057] When the angle of the support plate 303 needs to be adjusted to better adapt to the special structure or construction requirements of the bridge underside, the rotating motor connected to the worm gear 301 is activated. The rotating motor drives the worm gear 301 to rotate. Since the worm gear 301 meshes with the worm wheel 307 on the rotating frame 304, the rotation of the worm gear 301 drives the worm wheel 307 to rotate synchronously. The rotation of the worm wheel 307 drives the rotating frame 304, which is fixedly connected to it, to rotate around its connection point with the lifting plate 207. During the rotation, the construction personnel can stop or adjust the operation of the rotating motor at any time according to the actual situation, precisely control the rotation angle of the rotating frame 304, and thus achieve flexible adjustment of the angle of the support plate 303, enabling it to better adapt to different shapes of bridge undersides and ensuring stable, reliable, and highly conforming support for the bridge structure during bridge construction.

[0058] In summary, this utility model has the following beneficial effects:

[0059] 1. By utilizing a leveling instrument and the first electric telescopic boom in tandem, the levelness of the base can be quickly and accurately detected and adjusted. Construction personnel can precisely control the extension and retraction of the first electric telescopic boom via the control panel, adjusting the base to a level position based on the data from the leveling instrument. This provides a stable foundation for the entire support platform, ensuring that the platform will not tilt or sway due to uneven ground during bridge construction, guaranteeing the stability and safety of construction operations, and laying a solid and reliable foundation for subsequent construction.

[0060] 2. By adjusting the second electric telescopic rod and the rotating motor in the mechanism, the height of the support plate is given flexibility. The second electric telescopic rod can drive the rotating plate to rotate, increasing the contact area between the support plate and the underside of the bridge, making the support more stable and reliable. The rotating motor drives the rotating frame to rotate through a worm gear transmission, thereby flexibly adjusting the angle of the support plate. This design allows the support plate to better adapt to the bridge underside with different shapes and structures, achieving a close fit support, improving the adaptability of the support platform to various bridge construction scenarios, and effectively meeting diverse construction needs.
