Description

Technical Field

[0001] This invention relates to the field of bridge pier technology, specifically to an intelligent self-lifting and climbing integrated formwork device for bridge piers. Background Technology

[0002] In bridge construction, the construction of high piers is a common method, which plays a very important role in the stability of the bridge. To meet the needs of the project, climbing formwork has emerged. The emergence of climbing formwork construction technology has greatly reduced the difficulty of high pier construction and simplified the construction steps.

[0003] However, existing climbing formwork has some problems in use. It is not convenient to install and disassemble the existing climbing formwork, which will reduce the working efficiency of the device. At the same time, it is not convenient to restrict the movement trajectory when the device is moving. If the device moves rapidly downwards due to an accident, the existing technology is not convenient to handle and buffer it, which will reduce the safety of the device. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this invention is to provide an intelligent self-elevating and climbing integrated formwork device for high bridge piers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent self-elevating and climbing integrated formwork device for bridge piers, comprising a pier body, a fixing ring fitted on the outer edge of the pier body near the bottom, three hydraulic cylinders fixedly connected to the top of the fixing ring near the front and rear sides, a fixing plate fixedly connected to the top of each hydraulic cylinder, four first threaded holes on each fixing plate, and second bolts threadedly connected to each of the first threaded holes, two operating platforms fitted on the outer edge of the pier body near the center, the two operating platforms being arranged front and rear, several slots on the top of each operating platform, second threaded holes on the bottom of each slot, several baffles on the top of the operating platform near the outer edge, three threaded rods fixedly connected to the bottom of each baffle, several through holes on the top of the operating platform near the outer edge, the bottom end of each threaded rod penetrating adjacent through holes, and second nuts threadedly connected to the outer edge of each threaded rod near the bottom, with several second nuts located at the bottom of the operating platform.

[0006] Preferably, two support plates are fixedly connected to the side of the baffle closest to the high pier column body, and the side of the support plates away from the baffle is located in an adjacent slot. Each support plate is provided with a third threaded hole, and a third bolt is threaded into each of the third threaded holes. The bottom end of the third bolt is threaded into an adjacent second threaded hole.

[0007] Preferably, the operating platform has two grooves on the side near the high pier body, and several protrusions are provided on the front and rear sides of the high pier body near the left and right sides. Limiting grooves are provided on the side of the protrusions away from the high pier body near the top and bottom. A fourth threaded hole is provided on each limiting groove. Several fifth threaded holes are provided on the front and rear sides of the high pier body. A first bolt is threaded into each of the fourth threaded holes, and one end of the first bolt is threaded into the adjacent fifth threaded hole.

[0008] Preferably, each of the protruding plates has a connecting groove at the center of the side away from the main body of the pier, and each connecting groove has a swing plate hinged to its inner cavity. Each swing plate has a spring fixedly connected to the side of the swing plate close to the main body of the pier, and the end of the spring away from the swing plate is fixedly connected to the adjacent connecting groove.

[0009] Preferably, the inner cavity of the operating table is provided with connection holes near the left and right sides, and the front side of the operating table is provided with a first U-shaped rod near the left and right sides. The rear end of the first U-shaped rod is fixedly connected with two threaded anchor rods. The left and right sides of the operating table are fixedly connected with fixing pipes. The rear end of the threaded anchor rod passes through the adjacent connection hole or fixing pipe. The outer edge of the threaded anchor rod is threaded with a first nut near the front and rear sides.

[0010] Preferably, each of the operating tables has two connecting plates fixedly connected to its bottom. Each connecting plate has a U-shaped plate fixedly connected to its side away from the operating table. The U-shaped plate is fitted onto the outer edge of the adjacent convex plate. Each of the corresponding sides of the operating table has a storage slot near the left and right sides. Each storage slot has a magnet fixedly connected to its inner side. Two adjacent magnets are fitted together.

[0011] Preferably, each of the operating platforms is equipped with a ladder at the center of the side away from the main body of the high pier. Fixed plates are inserted into the top of each ladder on both sides. One side of each fixed plate is fixedly connected to the outer edge of the operating platform. A through groove is provided on each of the two middle baffles, and a movable plate is installed within the through groove. Two hinges are provided on the side of each movable plate away from the main body of the high pier. The movable plate is movably connected to one side of the adjacent baffle via the hinges. Blind holes are provided at the top of both the movable plate and the top of the middle baffle. A second U-shaped rod is provided in two adjacent blind holes.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention utilizes the interplay between the high pier column body, hydraulic cylinder, ladder, and swing plate to move two operating platforms to the surface of the high pier column body using hoisting equipment. Magnets on the two operating platforms attract each other, causing the platforms to rest on the top of a fixed plate on the hydraulic cylinder. The fixed plate supports the two operating platforms. A second bolt connects and limits the fixed plate and the operating platforms. A first U-shaped rod is then removed, driving a threaded anchor rod to move through the two operating platforms and adjacent fixed pipes. A first nut is rotated on the surface of the threaded anchor rod, connecting the two operating platforms through the threaded anchor rod. Multiple baffles are then removed, with the threaded rods at the bottom of the baffles passing through through holes in the operating platforms. A second nut is then rotated to the surface of the threaded rod, with its top fitting against the bottom of the operating platform. The baffles drive a support plate to move, placing the support plate within a slot on the top of the operating platform. A third bolt installs the support plate onto the surface of the operating platform, thus completing the installation of the baffles and ensuring operator safety.

[0014] When the operating platform needs to be moved upward, multiple hydraulic cylinders are activated. The hydraulic cylinders drive the operating platform upward through the fixed plate and the second bolt. The operating platform moves upward on the surface of the high pier column. The convex plate limits the movement trajectory of the operating platform. During the upward movement of the operating platform, it will drive the upper swing plate to move towards the high pier column. The swing plate will enter the connecting groove inside the convex plate and drive the spring to compress. If the hydraulic cylinder malfunctions during the upward movement of the operating platform, causing the operating platform to fall rapidly, the multiple swing plates below will abut against the operating platform when it moves downward. The swing plates will buffer the impact of the falling operating platform through the spring, thereby ensuring personnel safety. If it is found that the swing plate is broken afterward, the first bolt is turned and removed from the convex plate and the surface of the high pier column. The convex plate, swing plate and spring are then replaced. Attached Figure Description

[0028] Working principle: When the device starts working, the fixing ring 3 will be fitted onto the surface of the high pier column body 1. The two operating platforms 2 are moved to the surface of the high pier column body 1 by the hoisting equipment. The two operating platforms 2 are set one behind the other and attached to the surface of the high pier column body 1. The magnets 18 on the two operating platforms 2 attract each other. Then the operating platforms 2 will fall on the top of the fixing plate 11 on the top of the hydraulic cylinder 4. The fixing plate 11 supports the two operating platforms 2. The fixing plate 11 and the operating platforms 2 are connected and limited by the second bolt 12. The first U-shaped rod 15 is taken out. The first U-shaped rod 15 drives the threaded anchor rod 13 to move, and the threaded anchor rod 13 passes through the two operating platforms 2 and the adjacent fixing pipe 2. 5. Rotate the first nut 14 on the surface of the threaded anchor rod 13. The first nut 14 connects and installs the two operating platforms 2 through the engagement of the threaded anchor rod 13. The convex plate 7 is located in the groove on the operating platform 2, thereby restricting the vertical movement trajectory of the operating platform 2. Then, take out multiple baffles 6 and insert the threaded rod 23 at the bottom of the baffle 6 through the through hole on the operating platform 2. Then, rotate the second nut 24 to the surface of the threaded rod 23. The top of the second nut 24 fits against the bottom of the operating platform 2. The baffle 6 drives the support plate 21 to move. The support plate 22 is located in the slot on the top of the operating platform 2. The support plate 22 is installed on the surface of the operating platform 2 by the third bolt 22. This completes the installation of the baffle 6, ensuring the safety of the operator. The connecting plate 19, together with the U-shaped plate 20, provides auxiliary limiting. When the operating platform 2 needs to move upward, multiple hydraulic cylinders 4 are activated. The hydraulic cylinders 4 drive the operating platform 2 upward through the fixed plate 11 and the second bolt 12. The operating platform 2 moves upward on the surface of the high pier column body 1. The convex plate 7 limits the movement trajectory of the operating platform 2. During the upward movement of the operating platform 2, it will drive the upper swing plate 9 to move towards the high pier column body 1. The swing plate 9 will enter the connecting groove inside the convex plate 7 and drive the spring 10 to compress. If the operating platform 2 moves upward... If the hydraulic cylinder 4 malfunctions, causing the operating platform 2 to fall rapidly, multiple swing plates 9 below will abut against the operating platform 2 as it moves downward. The swing plates 9 will cushion the impact of the falling operating platform 2 through the spring 10, thus ensuring personnel safety. If it is found that the swing plates 9 are broken afterward, the first bolt 8 will be turned and removed from the surface of the protruding plate 7 and the high pier column body 1. The protruding plate 7, swing plates 9 and spring 10 will be replaced. After finishing the work, the second U-shaped rod 17 will be moved upward and removed from the inside of the movable plate 16 and the baffle 6. The movable plate 16 will be opened, and the operator can return to the ground through the escalator 5.
