Technical Field
[0001] This invention belongs to the field of pedestrian bridge construction technology, specifically relating to a device and method for adjusting the spatial position of connecting piers in an assembled pedestrian bridge. Background Technology
[0002] With rapid traffic growth, some main streets are constantly busy with vehicles, making it increasingly difficult for pedestrians to cross the road. Pedestrian overpasses in cities began to develop in the 1960s. Initially, overpasses were built simply to solve traffic problems at intersections. Later, with the accumulation of experience, the functions of pedestrian overpasses were gradually expanded to enrich the lives of urban residents. The length of overpasses also continued to increase, requiring them to be designed and constructed in a modular fashion.
[0003] After the pedestrian overpass is assembled, it needs to be erected on the piers in a fixed position. A crane lifts the assembled bridge and aligns it with the pier for placement. During the installation and placement process, there are problems with the connection points being difficult to align accurately. The space is too small to make manual adjustments, and multiple spatial adjustments are required, which affects the installation progress and poses safety hazards. Summary of the Invention
[0004] The purpose of this invention is to solve the aforementioned technical problems in the prior art and to provide a device and method for adjusting the spatial position of the connecting piers of a pedestrian overpass.
[0005] This invention, by incorporating an adjustment device, accurately connects the assembled pedestrian overpass to the bridge piers, achieving a highly accurate and efficient installation. This improves installation efficiency, ensures installation accuracy, and eliminates the need for manual adjustments by construction personnel, thus resolving the problem of difficult connection between the assembled pedestrian overpass and the bridge piers.
[0006] The adjustment device of this invention includes a lower lifting device, a middle fixing platform, and an upper rotating clamping device. In the adjustment method for assembling a pedestrian overpass and connecting it to a bridge pier, firstly, the bottom of the lower lifting device is fixed to both sides of the bridge pier, so that the upper lifting platform at the top of the lower lifting device is fitted onto the outside of the bridge pier. The middle fixing platform is then connected to the top of the lower lifting device, and the middle fixing platform is connected to the upper rotating clamping device. The adjustment device is assembled on the ground, which facilitates operation and improves the assembly accuracy of the adjustment device, thereby improving the connection accuracy between the assembled pedestrian overpass and the bridge pier. Then, the lower lifting device drives the middle fixing platform and the upper rotating clamping device to lift to the top of the bridge pier. The lifting height of the lower lifting device can be adjusted according to the connection height of the bridge pier. The applicability of the adjustment device has been improved. Next, the assembled pedestrian bridge is hoisted onto the upper rotating clamping device by a crane. The crane controls the insertion of the connecting part at the bottom of the assembled pedestrian bridge into the upper optional clamping device. The upper rotating clamping device clamps and fixes the connecting part of the assembled pedestrian bridge, ensuring that the connecting part and the pier are at a concentric angle. Then, the lower lifting device descends, and the crane simultaneously and slowly lowers the assembled pedestrian bridge, allowing it to connect with the pier. The lower lifting device continues to descend to the bottom of the pier and is then removed. This achieves rapid connection between the assembled pedestrian bridge and the pier while ensuring installation accuracy. It eliminates the need for operators to rise to the connection point for manual adjustment, thus eliminating safety hazards. Furthermore, the adjustment device is reusable.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0008] A spatial position adjustment device for the assembly of a pedestrian overpass and its connecting piers includes: a lower lifting device, a middle fixed platform, and an upper rotating clamping device. The lower lifting device is fitted onto the outside of the pier; the upper rotating clamping device is connected to the middle fixed platform. When the assembly of the pedestrian overpass and the pier are connected, the lower lifting device, fitted onto the outside of the pier, fixes the bottom of the middle fixed platform to the lower lifting device, and then connects the upper rotating clamping device to the middle fixed platform. The lower lifting device lifts the middle fixed platform and the upper rotating clamping device upwards to the top of the pier, where the upper rotating clamping device clamps the connecting part of the assembly of the pedestrian overpass and positions it on top of the pier. This invention, by setting up an adjustment device, accurately connects the assembly of the pedestrian overpass and the pier, achieving accurate and rapid connection, improving installation efficiency, ensuring installation accuracy, and eliminating the need for manual adjustment by construction personnel, thus eliminating installation hazards and solving the problem of difficult connection between the assembly of the pedestrian overpass and the pier.
[0009] Furthermore, the lower lifting device includes a lifting platform, a lifting frame, and an upper lifting platform. The bottom of the lifting frame is connected to the top of the lifting platform, and the top of the lifting frame is connected to the bottom of the upper lifting platform. The lifting platform is located on both sides of the bridge pier, and the upper lifting platform is fitted onto the outside of the bridge pier. A driving component is installed inside the lifting frame, which controls the lifting frame to raise and lower the upper lifting platform. The upper lifting platform has a fixing component, which connects the upper lifting platform to the middle fixing platform and also connects the lower lifting device to the bridge pier. The lifting platform supports and installs the lifting frame. When the bridge pier is connected to the assembled pedestrian overpass, the driving component drives the lifting frame to raise and lower the upper lifting platform. The lifting height of the lifting frame can be adjusted according to the connection height of the bridge pier, greatly improving the applicability of the adjustment device. Simultaneously, the upper lifting platform serves as a supporting connection.
[0010] Furthermore, the lifting frame adopts a scissor-type telescopic frame, and the driving component is a hydraulic rod. The extension and retraction of the hydraulic rod controls the lifting frame's raising and lowering. By pushing the hydraulic rod, the scissor-type telescopic frame is controlled to rise and fall, thereby realizing the lifting of the lifting frame.
[0011] Furthermore, the upper lifting platform includes two semi-circular annular plates, which abut against the outer side of the pier. Fixing components are circumferentially distributed on the two semi-circular annular plates. The fixing components include a synchronous motor, a connecting motor gear, a connecting rotating rod, a connecting limiting groove, and an external tooth internal threaded sleeve. The synchronous motor and the connecting limiting groove are both connected to the semi-circular annular plates. The connecting motor gear is connected to the drive end of the synchronous motor. The external tooth internal threaded sleeve is rotatably connected to the connecting limiting groove. The connecting rotating rod is threadedly connected to the external tooth internal threaded sleeve. The external tooth internal threaded sleeve meshes with the connecting motor gear. The synchronous motor controls the rotation of the connecting motor gear, thereby driving the connecting rotating rod to pass through the connecting limiting groove and abut against the pier. Two semi-circular ring plates form the upper lifting platform. The two semi-circular ring plates are fitted on the outside of the pier to support the middle fixed platform and the upper rotating clamping device. The synchronous motor drives the connecting motor gear to rotate. The connecting motor gear meshes with the external tooth internal thread sleeve, so that the connecting rotating rod moves along the direction of the external tooth internal thread sleeve. During the docking process, the synchronous motor drives the connecting rotating rod to move to one side of the pier, so that the end of the connecting rotating rod abuts against the outer wall of the pier, thereby fixing the lower lifting device to the pier.
[0012] Furthermore, the middle fixed platform includes an assembly platform, an upper connecting limit block, and a connector. The upper connecting limit block is fixed to the bottom of the assembly platform with a corresponding connecting limit groove. The upper connecting limit block has a connecting hole for the corresponding connecting rotating rod. Two adjacent assembly platforms are fixed together to form an annular platform through the connector. Fixed rotating columns are distributed around the top circumference of the annular platform. The fixed rotating columns are used to connect to the upper rotating clamping device. When the middle fixed platform is connected to the lower lifting device, the upper connecting limit block is inserted into the connecting limit groove. The synchronous motor controls the connecting rotating rod to pass through the connecting hole, so that the assembly platform is fixed on the upper lifting platform. Then, the two adjacent assembly platforms are fixed together through the connector. Two adjacent assembly platforms are fixed together by connector 1. Connector 1 facilitates quick assembly and disassembly between the assembly platforms. By inserting the upper connecting limit block into the connecting limit groove, the middle fixed platform is positioned and installed on the lower lifting device. At the same time, a connecting hole is provided on the upper connecting limit block. By inserting the connecting rotating rod into the connecting hole, the middle fixed platform is fixedly connected to the lower lifting device.
[0013] Furthermore, the connector includes a connecting plate on the assembly platform, a lower connecting plate on the assembly platform, bolts, and nuts. The connecting plate on the assembly platform is tightly attached to the top surface of two adjacent assembly platforms, and the lower connecting plate is tightly attached to the bottom surface of two adjacent assembly platforms. The bolt passes through the connecting plate on the assembly platform, the assembly platform, and the lower connecting plate. The nut is screwed into the end of the bolt and tightened onto the lower connecting plate. By setting connecting plates on the assembly platform and lower connecting plates at the top and bottom ends of two adjacent assembly platforms respectively, and then passing bolts through the connecting plates and lower connecting plates before screwing in nuts for fixation, a fixed connection between two adjacent assembly platforms is achieved.
[0014] Furthermore, the upper rotating clamping device includes an assembly frame, a second connector, and a clamping component. Two adjacent assembly frames are fixed together by the second connector to form a ring-shaped frame. The clamping component is located within the assembly frame and is mounted on a fixed rotating column. A control component is provided on the assembly platform to control the clamping component to clamp onto the connecting part of the assembled pedestrian bridge. The center of the upper lifting platform, the center of the ring platform, and the center of the ring-shaped frame are on the same vertical line. The second connector is used to assemble two adjacent assembly frames. The clamping component is used to clamp the connecting part of the assembled pedestrian bridge and to control that the center of the connecting part and the center of the pier connection are on the same vertical line.
[0015] Furthermore, connector two includes an upper frame connecting piece, a lower frame connecting piece, an upper fixing bolt, a lower fixing bolt, a connecting bolt, and a connecting nut. The upper fixing bolt secures the upper frame connecting piece to the top surface of two adjacent assembled frames, and the lower fixing bolt secures the lower frame connecting piece to the bottom surface of two adjacent assembled frames. A connecting bolt is screwed between the two adjacent assembled frames, and a connecting nut is screwed into the end of the connecting bolt, tightening the connecting nut onto the assembled frame. By securing the upper frame connecting piece to the top of two adjacent assembled frames with the upper fixing bolt and the lower fixing bolt to the bottom of two adjacent assembled frames, the two adjacent assembled frames are securely connected. The connecting bolt passes through the two adjacent assembled frames and is then screwed into the connecting nut for further fixation, further increasing the stability of the connection between the assembled frames.
[0016] Furthermore, the clamping component includes a fixed rotating frame, a rotating arm, and a clamping roller. The rotating arm is inserted into the fixed rotating frame, which is rotatably connected to the assembly frame. One end of the rotating arm has a through hole, and the fixed rotating column is inserted into the through hole, so that the rotating arm and the fixed rotating column are rotatably connected. The clamping roller is located at the other end of the rotating arm. The control component includes a motor platform, a rotary motor, a motor rotating threaded rod, and a threaded rotating block. The motor platform is connected to the assembly platform, the rotary motor is rotatably connected to the motor platform, the motor rotating threaded rod is connected to the output end of the rotary motor, and the threaded rotating block is threadedly connected to the motor rotating threaded rod. The bottom of the threaded rotating block has a protrusion, and the assembly frame has a corresponding assembly frame connecting groove. The protrusion is inserted into the assembly frame connecting groove. The rotary motor controls the rotation of the motor rotating threaded rod, thereby controlling the threaded rotating block to drive the assembly frame to rotate. The rotating arm drives the clamping roller to swing, so that the clamping roller clamps onto the connecting part of the assembly pedestrian overpass. The fixed rotating column is used to connect one end of the rotating arm, serving a positioning and installation function, while also allowing one end of the rotating arm to swing around the fixed rotating column. The protrusion and the connecting groove of the assembly frame also serve a positioning and installation function, while causing the threaded rotating block to drive the assembly frame to rotate. The rotating motor drives the motor to rotate the threaded rod, causing the threaded rotating block to move along the direction of the motor's rotation of the threaded rod. The threaded rotating block drives the assembly frame to rotate, while the rotating motor rotates on the motor platform. The fixed rotating frame drives the rotating arm to rotate, causing the rotating arm to drive the clamping roller to swing, thereby controlling the clamping roller to clamp and release the connection part.
[0017] A method for adjusting the spatial position adjustment device of the connecting piers of an assembled pedestrian overpass includes the following steps:
[0018] a. First, the lower lifting device is installed at the predetermined position on both sides of the bridge pier by installing and fixing the lifting platform at the predetermined position on both sides of the bridge pier; a fence is set up around the perimeter and warning signs are hung to inform people of the safety hazards; during the adjustment of the device, a warning sound is played to warn people.
[0019] b. Insert the upper connecting limit block into the connecting limit groove at the top of the lower lifting device. Then, the synchronous motor controls the connecting rotating rod to rotate, causing the connecting rotating rod to move towards the pier side, so that the connecting rotating rod is inserted into the connecting hole of the upper connecting limit block, thereby connecting the middle fixed platform to the lower lifting device.
[0020] c. Through the through hole on the rotating arm, the fixed rotating column is inserted into the through hole, thereby rotating the rotating arm onto the fixed rotating column. At the same time, the protrusion on the threaded rotating block is inserted into the connecting groove of the assembly frame, thereby connecting the upper rotating clamping device with the middle fixed platform.
[0021] d. After assembling the lower lifting device, the middle fixed platform and the upper rotating clamping device, the hydraulic rod controls the scissor-type telescopic frame to rise, so that the lower lifting device is lifted upward, driving the middle fixed platform and the upper rotating clamping device to be lifted upward to the planned position at the top of the pier. Then the synchronous motor is started again, controlling the connecting rotating rod to move towards the pier again, so that the connecting rotating rod is pressed against the outside of the pier, thereby fixing the top of the lower lifting device to the pier.
[0022] e. Lift the assembled pedestrian bridge to the top of the adjustment device using a crane, and control the connecting part of the assembled pedestrian bridge to be inserted into the assembly frame. Drive the rotating arm to rotate using a rotary motor, so that the clamping rollers are clamped on the outer wall of the connecting part, and the connecting part of the assembled pedestrian bridge and the pier are concentric.
[0023] f. The synchronous motor starts again, controlling the connecting rotating rod to move away from the pier, so that the lower lifting device is separated from the pier. Then, the scissor telescopic frame is lowered by the hydraulic rod, so that the lower lifting device drives the middle fixed platform and the upper rotating clamping device to descend. The assembled pedestrian bridge lifted by the crane is also slowly lowered until the assembled pedestrian bridge is connected to the pier.
[0024] g. After the docking is completed, the hydraulic rod controls the scissor-type telescopic frame to continue to descend, so that the lower lifting device drives the middle fixed platform and the upper rotating clamping device to descend to the bottom of the pier. The adjustment device is disassembled, the second connector is removed, the frame is disassembled and assembled, the first connector is removed, the platform is disassembled and assembled, and finally the lower lifting device is removed.
[0025] The present invention, by adopting the above-described technical solution, has the following beneficial effects:
[0026] This invention, by incorporating an adjustment device, accurately connects the assembled pedestrian overpass to the bridge piers, achieving a highly accurate and efficient installation. This improves installation efficiency, ensures installation accuracy, and eliminates the need for manual adjustments by construction personnel, thus resolving the problem of difficult connection between the assembled pedestrian overpass and the bridge piers.
[0027] The adjustment device consists of a lower lifting device, a middle fixed platform, and an upper rotating clamping device. The lower lifting device controls the height adjustment of the middle fixed platform and the upper rotating clamping device. During the docking process between the bridge pier and the assembled pedestrian bridge, the lower lifting device controls the lifting height, which facilitates the upper rotating clamping device to clamp the connecting part of the assembled pedestrian bridge. When the lower lifting device descends, it can drive the assembled pedestrian bridge to descend and dock with the bridge pier. The lower lifting device can be adjusted according to the docking height of the bridge pier, adapting to bridge piers of various heights and increasing the applicability of the adjustment device.
[0028] The central fixed platform is used to fix the upper rotating clamping device to the lower lifting device. By inserting the upper connecting limit block into the connecting limit groove, and then driving the connecting rotating rod with a synchronous motor to insert it into the connecting hole of the upper connecting limit block, the central fixed platform is connected to the lower lifting device. The synchronous motor then drives the connecting rotating rod to move, so that the end of the connecting rotating rod is pressed against the outer wall of the pier, thus fixing the lower lifting device to the pier and increasing the stability of the adjustment device during operation. At the same time, after the synchronous motor controls the connecting rotating rod to press against the pier, the center of the upper lifting platform, the center of the assembly platform, and the center of the assembly frame are on the same vertical straight line.
[0029] The assembled pedestrian bridge is lifted by a crane to the top of the adjustment device, and the connecting part of the assembled pedestrian bridge is inserted into the assembly frame. The rotating arm is controlled by a rotary motor to rotate, so that the clamping rollers are clamped on the outer wall of the connecting part, thereby fixing the assembled pedestrian bridge to the upper rotating clamping device. At the same time, the clamping rollers clamp the connecting part so that the center of the connecting part and the center of the docking point of the bridge pier are on the same vertical straight line. Then, the lower lifting device controls the adjustment device to descend, so that the connecting part is inserted into the docking point of the bridge pier, thus achieving a precise and accurate docking of the assembled pedestrian bridge and the bridge pier.
[0030] The lower jacking device controls the middle fixed platform and the upper rotating clamping device to descend to the bottom of the pier. The upper rotating clamping device is removed through connector two, the middle fixed platform is removed through connector one, and then the lower jacking device is removed. This allows the adjustment device to be reused multiple times. Attached Figure Description

When the assembled pedestrian overpass 4 is connected to the pier 5, the lower lifting device 1 is fitted onto the outside of the pier 5, fixing the bottom of the middle fixing platform 2 to the lower lifting device 1. Then, the upper rotating clamping device 3 is connected to the middle fixing platform 2.

The lifting platform 7 is used to support and install the lifting frame 8. When the pier 5 is connected to the assembled pedestrian overpass 4, the driving component drives the lifting frame 8 to drive the upper lifting platform 9 to rise and fall. The lifting height of the lifting frame 8 can be adjusted according to the connection height of the pier 5, which greatly improves the applicability of the adjustment device. At the same time, the upper lifting platform 9 plays a supporting and connecting role. The lifting frame 8 adopts a scissor-type telescopic frame, and the driving component is a hydraulic rod 11. The extension and retraction of the hydraulic rod 11 controls the lifting frame 8 to rise and fall.

Two semi-circular ring plates 12 form the upper lifting platform 9. The two semi-circular ring plates 12 are sleeved on the outside of the pier 5 to support the middle fixed platform 2 and the upper rotating clamping device 3. The synchronous motor 13 drives the connecting motor gear 14 to rotate.

The rotating arm 40 drives the clamping roller 41 to swing, so that the clamping roller 41 clamps on the connecting part 6 of the assembly pedestrian overpass 4. The fixed rotating column 23 is used to connect one end of the rotating arm 40, serving as a positioning and installation function, and also allowing one end of the rotating arm 40 to swing around the fixed rotating column 23. The protrusion 47 and the connecting groove 48 of the assembly frame also serve as a positioning and installation function, while causing the threaded rotating block 46 to drive the assembly frame 28 to rotate. The rotating motor 44 drives the motor rotating threaded rod 45 to rotate, causing the threaded rotating block 46 to move along the direction of the motor rotating threaded rod 45. The threaded rotating block 46 drives the assembly frame 28 to rotate, while the rotating motor 44 rotates on the motor platform 43. The fixed rotating frame 39 drives the rotating arm 40 to rotate, causing the rotating arm 40 to drive the clamping roller 41 to swing, thereby controlling the clamping roller 41 to clamp and release the connecting part 6.
[0050] like Figures 8 to 12 As shown, a method for adjusting the spatial position of a connecting pier of an assembled pedestrian overpass includes the following steps:
[0051] a. First, the lower lifting device 1 is installed at the predetermined position on both sides of the pier 5 by installing and fixing the lifting platform 7 at the predetermined position on both sides of the pier 5; a fence is set up around the perimeter and warning signs are hung to inform people of the safety hazards; a warning sound is accompanied by a warning sound during the adjustment of the device.
[0052] b. Insert the upper connecting limit block 19 into the connecting limit groove 16 at the top of the lower lifting device 1. Then, the synchronous motor 13 controls the connecting rotating rod 15 to rotate, so that the connecting rotating rod 15 moves to the side of the pier 5 and inserts the connecting rotating rod 15 into the connecting hole 21 of the upper connecting limit block 19, thereby connecting the middle fixed platform 2 to the lower lifting device 1.
[0053] c. Through the through hole 42 on the rotating arm 40, the fixed rotating column 23 is inserted into the through hole 42, thereby rotating the rotating arm 40 onto the fixed rotating column 23. At the same time, the protrusion 47 on the threaded rotating block 46 is inserted into the assembly frame connecting groove 48, thereby connecting the upper rotating clamping device 3 with the middle fixed platform 2.
[0054] d. After assembling the lower lifting device 1, the middle fixed platform 2 and the upper rotating clamping device 3, the hydraulic rod 11 controls the scissor-type telescopic frame to rise, so that the lower lifting device 1 is lifted upward, driving the middle fixed platform 2 and the upper rotating clamping device 3 to be lifted upward to the planned position at the top of the pier 5. Then the synchronous motor 13 is started again, controlling the connecting rotating rod 15 to move towards the pier 5 again, so that the connecting rotating rod 15 is pressed against the outside of the pier 5, thereby fixing the top of the lower lifting device 1 to the pier 5.
[0055] e. The assembled pedestrian bridge 4 is lifted by a crane to the top of the adjustment device, and the connecting part 6 of the assembled pedestrian bridge 4 is inserted into the assembly frame 28. The rotating arm 40 is rotated by the rotating motor 44, so that the clamping roller 41 is clamped on the outer wall of the connecting part 6, and the connecting part 6 of the assembled pedestrian bridge 4 and the pier 5 are concentric.
[0056] f. The synchronous motor 13 starts again, controlling the connecting rotating rod 15 to move away from the pier 5, so that the lower lifting device 1 is separated from the pier 5. Then, the hydraulic rod 11 controls the scissor telescopic frame to descend, so that the lower lifting device 1 drives the middle fixed platform 2 and the upper rotating clamping device 3 to descend. The assembled pedestrian bridge 4 lifted by the crane is also slowly lowered until the assembled pedestrian bridge 4 is connected to the pier 5.
[0057] g. After the docking is completed, the hydraulic rod 11 controls the scissor-type telescopic frame to continue to descend, so that the lower lifting device 1 drives the middle fixed platform 2 and the upper rotating clamping device 3 to descend to the bottom of the pier 5. The adjustment device is disassembled, the connecting part 29 is removed, the frame is disassembled and assembled, the connecting part 20 is removed, the platform 18 is disassembled and assembled, and finally the lower lifting device 1 is removed.
[0058] This invention, by setting up an adjustment device, is used to accurately connect the assembled pedestrian overpass 4 and the pier 5, achieving accurate and rapid results, improving installation efficiency, ensuring installation accuracy, and eliminating the need for manual adjustment by construction personnel, thus eliminating installation hazards and solving the problem of difficult connection between the assembled pedestrian overpass 4 and the pier 5.
[0059] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
