Hydraulic climbing formwork is an advanced construction method that uses hydraulic equipment to make the formwork automatically climb up along the pier column without the need for lifting equipment. When in use, a set of hydraulic climbing formwork is installed on the side of the pier column. Through two crawling platforms and hydraulic cylinders, the crawling platforms are driven to move upward along the longitudinal track in an alternating manner, thereby driving the climbing formwork frame to move upward.

[0026] Working principle: When working, first install the track body 201 longitudinally on the high pier of the bridge through the installation nails 3, and then climb upward through the staggered two crawling platforms 401, driving the climbing formwork frame 5 to move upward, wherein when the output end of the hydraulic cylinder 402 is in a fully extended state, the span of the two crawling platforms 401 is three fixed blocks 2031, and when the output end of the hydraulic cylinder 402 is in a fully retracted state, the span of the two crawling platforms 401 is two fixed blocks 2031. When crawling upward, in the original state, the output end of the hydraulic cylinder 402 is in a fully extended state, at this time, the upper crawling platform 401 and the fixed connection unit 2 03 clamping, control the output end of the hydraulic cylinder 402 to retract, pull the lower crawling platform 401 to move upward, and then control the lower crawling platform 401 to clamp with the corresponding fixed connection unit 203, while the upper crawling platform 401 is disengaged from the fixed connection unit 203, control the output end of the hydraulic cylinder 402 to extend, and under the action of the reverse force, the upper crawling platform 401 moves upward, and then the cycle is repeated, so that the two crawling platforms 401 move upward, thereby driving the climbing formwork frame 5 to move upward. When the climbing formwork frame 5 moves upward to the required height, both crawling platforms 401 are clamped with the fixed connection unit 203; During the crawling process, when the crawling platform 401 needs to be connected with the fixed connection unit 203, the first electromagnet 4045 is controlled to be energized to generate a repulsive force on the first magnetic block 4049, thereby pushing the middle column 4047 to move toward the side of the track body 201. After the middle column 4047 moves, the elastic force of the first spring 40412 pulls the inner plate 4043 toward the fixed block 2031, pushing the two clamping plates 4044 to be inserted into the first slot 2032. After the clamping plates 4044 are inserted into the first slot 2032, the middle column 404 7 continues to move so that the end plate 4048 generates a thrust on the pressure rod 4057, pushing the movable plate 4053 to move, and pushing the clamping rod 4054 toward the inner side of the second slot 2033 through the first connecting rod 4055 to clamp into the first clamping groove 2034, thereby further improving the clamping stability of the single crawling platform 401 and the fixed block 2031. At this time, the other crawling platform 401 is disengaged from the fixed block 2031, and then the loose crawling platform 401 is driven to move by the hydraulic cylinder 402, thereby driving the climbing formwork frame 5 to climb upward along the track body 201; When the climbing formwork needs to be fixed, the first electromagnet 4045 is energized to insert the clamping plate 4044 into the first slot 2032 and to clamp the clamping rod 4054 into the first clamping slot 2034. In this stage, the middle through slot 4066 is closed by the two baffles 4068, so that the end of the middle plug block 4061 is blocked by the baffle 4068. When the middle column 4047 moves toward the side of the track body 201, the limiting inner plate 4063 moves relative to the middle plug block 4061 toward the inside of the limiting inner slot 4062, so that the third spring 4065 is stretched. Then, the second electromagnet 40611 is energized to generate an attraction force on the second magnetic block 40610, so that the baffle 4068 enters the plate slot 4067, thereby opening the middle slot 4066. At this time, the baffle 4068 no longer blocks the middle plug block 4061. At this time, the middle plug block 4061 passes through the middle slot 4066 and enters the second slot 2033 under the elastic force of the third spring 4065, thereby improving the clamping stability. After the middle plug block 4061 enters the second slot 2033, the limiting inner plate 4063 is in the limiting position. A movement margin is generated inside the inner groove 4062, so that the middle column rod 4047 can continue to move toward the side of the fixed block 2031, so that the end plate 4048 continues to push the pressure rod 4057 to move, thereby continuing to push the clamping rod 4054 to move along the first clamping groove 2034 toward the inside of the second slot 2033, so that the clamping rod 4054 is inserted into the inside of the transverse groove 4072, so that the crawling clamping unit 404 is clamped with the middle plug block 4061, so that the crawling platform 401 is clamped and self-locked, thereby improving the fixing stability of the crawling platform 401; When the clamping rod 4054 is inserted into the transverse groove 4072, the transverse block 4074 is pushed to move along the transverse groove 4072, thereby pushing the two transverse plates 4073 closer to each other, and then the two longitudinal plates 4077 are pushed away from each other through the second connecting rod 40710, pushing the longitudinal block 4078 to move outward from the longitudinal groove 4076 and clamped into the contact point 2036, thereby further clamping the crawling platform 401 and improving the fixing stability of the crawling platform 401 When the upper longitudinal moving block 4078 enters into the contact 2036, the two ends of the conductive rod 4079 are respectively in contact with the two contacts 2036, so that the fan 2039 is energized, and when the card plate 4044 is inserted into the first slot 2032, the end face of the suction cup 2038 is tightly attached to the side wall of the card plate 4044. Under the action of the fan 2039, the suction cup 2038 and the card plate 4044 are negatively adsorbed, thereby producing an auxiliary fixing effect, thereby improving the installation stability of the climbing formwork frame 5.
