[0002] The utility model with announcement number: CN218059921U belongs to the technical field of bridge construction, and is particularly a truss integral lifting type bridge high pier climbing formwork device, comprising a concrete foundation and a bridge pier fixedly arranged on the top of the concrete foundation, wherein four support plates are fixedly arranged on the top of the concrete foundation, and guide grooves are provided on the inner sides of the four support plates, and a connecting plate is provided in the sliding sleeve in the guide groove, and the same truss operating platform is fixedly arranged between the four connecting plates. The utility model can smoothly lift the truss operating platform as a whole through the cooperation of a box body, a winding motor, a rotating shaft, a winding disk, a wire rope, a fixed pulley, a connecting plate and a truss operating platform, so that the process is reduced and the adjustment is faster. Through the cooperation of a mounting seat, a fixing bolt, a reinforcing rib, a support plate and a guide groove, the truss operating platform can be stably guided, further improving the stability of the truss operating platform during lifting and lowering, and ensuring the safety during construction.

[0003] However, due to the lack of the function of fixing the operating platform in the above technical solution, in actual use, the operating platform is moved by pulling the steel wire rope and is fixed by the steel wire rope support. The steel wire rope is easily corroded or scratched after long-term use, causing damage, which affects the stability of the operating platform and has certain safety hazards. Therefore, we propose a high pier climbing formwork device for bridges to solve the above-mentioned technical problems. Utility Model Content

[0029] Embodiment 1

[0030] Reference Figure 1-4 A high pier climbing formwork device for a bridge comprises a foundation 1, four support plates 2, an operating platform 3 and a pier 4. The four support plates 2 are symmetrically fixedly connected to the top of the foundation 1, the operating platform 3 is slidably connected to one side of the corresponding support plate 2, the outer wall of the pier 4 is adapted to the inner wall of the operating platform 3, a plurality of positioning holes are evenly spaced on one side of the four support plates 2, the front and rear sides of the operating platform 3 are fixedly connected with a limiting plate 6, the outer walls of the two limiting plates 6 are slidably connected with a push plate 5, the front and rear sides of the operating platform 3 are symmetrically slidably connected with positioning rods 14, and the number of the positioning rods 14 is four, the four positioning rods 14 are adapted to the corresponding positioning holes, and the front and rear sides of the operating platform 3 are provided with a control mechanism, which controls The mechanism includes two rotating rods 9, two fixed shafts 10, two contact plates 11 and two push rods 12. The two rotating rods 9 are rotatably connected to one side of the corresponding push plate 5. The two fixed shafts 10 are respectively fixedly connected to the front and rear sides of the operating platform 3, and the outer walls of the two rotating rods 9 are movably contacted with the outer walls of the corresponding fixed shafts 10. The two contact plates 11 are slidably connected to the left side of the corresponding limiting plate 6. The bottom of the two rotating rods 9 is movably contacted with the top of the corresponding contact plate 11. The two push rods 12 are rotatably connected to the front side of the corresponding contact plate 11. The rear side of the two push rods 12 is rotatably connected to the front side of the corresponding positioning rod 14. The right side of the two push plates 5 is fixedly connected to the left side of the corresponding positioning rod 14.

[0031] By means of the above mechanism: the push plate 5 is used to conveniently drive the positioning rod 14 on the right to move left, and when the rotating rod 9 moves, it will contact the fixed shaft 10. At this time, the rotating rod 9 rotates and pushes the contact plate 11 to move downward, and when the contact plate 11 moves, it will push the push rod 12, and the positioning rod 14 on the left can be driven to move right through the push rod 12. At this time, the two positioning rods 14 on the same side move toward each other and disengage from the positioning holes to unlock the operating platform 3, thereby facilitating the up and down movement of the operating platform 3 and keeping the operating platform 3 stable when fixed, preventing the wire rope from being damaged and causing the operating platform 3 to lose support and fall or tilt, thereby avoiding safety hazards.

[0032] In the utility model, the two limiting plates 6 are fixedly connected with a fixing sleeve 7 on one side away from each other, and the inner walls of the two fixing sleeves 7 are slidably connected to the outer walls of the corresponding push plates 5. The fixing sleeve 7 is used to limit the push plates 5 so that the push plates 5 can move stably laterally.

[0033] In the utility model, the right sides of the two limiting plates 6 are fixedly connected to the No. 1 spring 8, and the left sides of the two push plates 5 are fixedly connected to the corresponding right sides of the No. 1 spring 8. The elastic force of the No. 1 spring 8 facilitates the push plates 5 to be pushed back to their original positions.

[0034] In the utility model, the tops of the two limiting plates 6 are fixedly connected with No. 2 springs 13, and the bottoms of the two contact plates 11 are fixedly connected with the tops of the corresponding No. 2 springs 13. Through the elastic force of the No. 2 springs 13, it is convenient to push the contact plates 11 to reset, thereby driving the positioning rod 14 on the left to reset.

[0035] In the utility model, the two push plates 5 are fixedly connected to the side close to each other with a limiting shaft, and the outer walls of the two limiting shafts are in active contact with the outer walls of the corresponding rotating rods 9. The limiting shafts can be used to conveniently limit the rotation angle of the rotating rods 9 to prevent the rotating rods 9 from rotating excessively and failing to contact the fixed shaft 10.

[0036] Working principle: In actual use, when the operating platform 3 needs to be climbed, first push the push plate 5 to move horizontally. When the push plate 5 moves horizontally, it will compress the No. 1 spring 8 and drive the rotating rod 9 to move horizontally. At the same time, the push plate 5 will drive the positioning rod 14 on the right to move left. When the rotating rod 9 moves, it will contact the fixed shaft 10. At this time, the rotating rod 9 rotates and pushes the contact plate 11 to move downward. When the contact plate 11 moves, it will push the push rod 12 and compress the No. 2 spring 13. The positioning rod 14 on the left can be driven to move right through the push rod 12. At this time, the two positioning rods 14 on the same side move to the side close to each other and break contact with the positioning holes, so that the operating platform 3 is unlocked, and the inner part of the support plate 2 is unlocked. A driving assembly is provided on the wall, which can drive the operating platform 3 to move up and down. When the operating platform 3 moves to a suitable height, the push plate 5 is released. At this time, the No. 1 spring 8 loses its restriction and pushes the push plate 5 to move right and reset. At the same time, the push plate 5 will drive the right positioning rod 14 to reset and drive the rotating rod 9 to reset. At this time, the No. 2 spring 13 loses its restriction and pushes the contact plate 11 to move upward. The push rod 12 is pulled by the contact plate 11 to make the left positioning rod 14 move left. At this time, the two positioning rods 14 on the same side move to the side away from each other. At this time, the positioning rod 14 is engaged with the positioning hole to fix the operating platform 3 at the current height, so that the operating platform 3 remains stable during use.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
