Description
Technical Field
[0001] This utility model relates to the field of climbing formwork fall prevention technology, and in particular to a hydraulic climbing formwork fall prevention protection device. Background Technology
[0002] Climbing formwork, short for climbing scaffolding, consists of three parts: climbing formwork, climbing frame, and climbing equipment. It is an effective tool in the construction of tall structures such as shear wall systems, cylindrical tube systems, and bridge piers. Because of its self-climbing capability, it eliminates the need for lifting machinery, reducing the workload of transport equipment during construction. Suspending scaffolding on the self-climbing formwork eliminates the need for external scaffolding during construction.
[0003] In climbing formwork fall protection technology, existing hydraulic climbing formwork devices usually rely on only a single fall protection mechanism. This often results in unsatisfactory protection when the climbing formwork frame itself falls unexpectedly. If the hydraulic system fails or other factors cause the fall protection device to fail to respond in time, the climbing formwork frame itself may fall violently, posing a huge safety hazard to the equipment and workers.
[0004] Therefore, we propose a hydraulic climbing formwork fall protection device. Utility Model Content
[0005] The present invention aims to solve the technical problems existing in the prior art and provide a hydraulic climbing formwork anti-fall protection device.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a hydraulic climbing formwork anti-fall protection device, comprising a wall, a sliding frame body, and a climbing formwork frame body. A slider driven by a hydraulic system is slidably connected to the inner wall of the sliding frame body. The outer wall of the slider is fixedly connected to the climbing formwork frame body, and a rack is fixedly installed on the outer wall of the slider. A first anti-fall mechanism is provided on one inner wall of the sliding frame body, comprising a mounting block, a fixed shaft, a baffle, and a gear. A side rail is provided on the side wall of the sliding frame body away from the climbing formwork frame body. A support block is slidably connected to the side rail and fixedly connected to the slider. A fixed plate is fixedly connected to the bottom wall of the support block via a support column. A buffer plate is provided below the fixed plate, and a second anti-fall mechanism is provided on the buffer plate. The second anti-fall mechanism comprises a round rod, a buffer block, a buffer spring, a connecting rod, and a fixed block.
[0007] As a preferred technical solution of this utility model, the gear is rotatably connected to the sliding frame body through a rotating shaft, the gear meshes with the rack, and the gear contacts the bottom end of the baffle. The mounting block is fixedly installed on the inner wall of the sliding frame body, and the mounting block is located above the gear. The top wall of the mounting block is provided with a slot, and the two ends of the fixed shaft are fixedly connected to the inner wall of the slot.
[0008] As a preferred technical solution of this utility model, the baffle is an L-shaped structure, the baffle is rotatably connected to the outer wall of the fixed shaft, the baffle has a rectangular groove inside, and the fixed shaft passes through the rectangular groove. The torsion spring is sleeved on the surface of the fixed shaft and the torsion spring is located in the rectangular groove.
[0009] As a preferred technical solution of this utility model, the outer walls of the fixing plate and the buffer plate are slidably connected to the inner walls of the side rail, and the top wall of the buffer plate is provided with an installation groove, and the two ends of the round rod are respectively fixedly connected to the inner walls of the front and rear sides of the installation groove.
[0010] As a preferred embodiment of this utility model, the two buffer blocks are slidably sleeved on both ends of the round rod, and the buffer spring is fixedly sleeved on the outer wall of the round rod, with both ends of the buffer spring being fixedly connected to the wall surface of the two buffer blocks that are close to each other.
[0011] As a preferred embodiment of this utility model, there are two connecting rods, which are inclined. The bottom ends of the two connecting rods are movably connected to two buffer blocks, and the top ends of the two connecting rods are movably connected to fixed blocks.
[0012] As a preferred technical solution of this utility model, push blocks are fixedly connected to the end walls of the two buffer blocks that are far apart from each other, and buffer frames are fixedly connected to the top walls of both sides of the buffer plate through support seats, and the buffer frames are C-shaped spring sheets.
[0013] This utility model provides a hydraulic climbing formwork fall protection device. It has the following beneficial effects:
[0014] 1. This hydraulic climbing formwork fall protection device, in use, when the slider driven by the hydraulic system slides upward, the rack drives the gear to rotate, and the outer wall of the gear can push open the baffle to ensure that the baffle does not affect the normal upward movement of the slider. When the climbing formwork frame body falls due to an accident, the sliding slider drives the rack to mesh with the gear, triggering the reset action of the torsion spring. When the gear tooth groove contacts the baffle, the first torsion spring will pull the baffle back and lock it into the tooth groove, thereby achieving blocking and locking, preventing the climbing formwork frame body from continuing to fall, and fixing it in the current position to avoid accidents.
[0015] 2. In the case of this hydraulic climbing formwork fall protection device, when the climbing formwork frame body falls and the first fall protection mechanism malfunctions, the slider will drive the support block to move synchronously until the support block reaches the lowest end of the sliding frame body. At this time, the support block pushes the support column and the fixed plate to move downwards. The fixed block drives the bottom ends of the two connecting rods to move away from each other, thereby driving the two buffer blocks to move in opposite directions on the round rod. During this process, the buffer spring is stretched, and the extension force of the buffer spring plays a buffering role. As the two buffer blocks move, the two push blocks will apply compressive force to the two buffer frames. With the mechanical principle of the arc structure, the arc can evenly distribute the pressure. Because the arc has the strongest compressive capacity in structural mechanics, this design can effectively reduce the impact force when the climbing formwork frame body falls and provide the maximum shock absorption protection for the climbing formwork frame body.

A buffer plate 26 is located below the fixing plate 25. A second anti-fall mechanism is installed on the buffer plate 26. The second anti-fall mechanism includes a round rod 28, a buffer block 29, a buffer spring 30, a connecting rod 31, and a fixing block 32. A gear 20 is rotatably connected to the sliding frame body 11 via a rotating shaft. The gear 20 meshes with a rack 21 and contacts the bottom end of the baffle 17. A mounting block 15 is fixedly installed on the inner wall of the sliding frame body 11, and is located above the gear 20. The top wall of plate 5 has a slot, and the two ends of the fixed shaft 16 are fixedly connected to the inner wall of the slot. The baffle 17 has an L-shaped structure and is rotatably connected to the outer wall of the fixed shaft 16. The inside of the baffle 17 has a rectangular groove 18, and the fixed shaft 16 passes through the rectangular groove 18. The torsion spring 19 is sleeved on the surface of the fixed shaft 16 and is located in the rectangular groove 18. The outer walls of the fixed plate 25 and the buffer plate 26 are slidably connected to the inner wall of the side rail 22, respectively. The top wall of the buffer plate 26 has a mounting groove 27, and the two ends of the round rod 28 are fixedly connected to the inner walls of the front and rear sides of the mounting groove 27, respectively. Two buffer blocks 29 The buffer springs 30 are fixedly sleeved on the outer wall of the round rod 28 and the two ends of the buffer springs 30 are fixedly connected to the wall of the two buffer blocks 29 that are close to each other. There are two connecting rods 31, which are inclined.

[0024] The working principle of this utility model is as follows: During use, when the slider 12, driven by the hydraulic system, slides upward, the rack 21 drives the gear 20 to rotate. The outer wall of the gear 20 can push open the baffle 17, ensuring that the baffle 17 does not affect the normal upward movement of the slider 12. When the climbing formwork frame body 13 falls due to an accident, the sliding slider 12 drives the rack 21 to mesh with the gear 20, triggering the reset action of the torsion spring 19. When the tooth groove of the gear 20 contacts the baffle 17, the first torsion spring 19 will pull the baffle 17 back and lock it into the tooth groove, thereby achieving blocking and locking, preventing the climbing formwork frame body 13 from continuing to fall, and fixing it in its current position to avoid accidents. In addition, a second anti-fall protection mechanism is also set. When the climbing formwork frame body 13 falls and the first anti-fall mechanism malfunctions, the slider 12... This will cause the support block 23 to move synchronously until the support block 23 reaches the lowest end of the sliding frame body 11. At this time, the support block 23 pushes the support column 24 and the fixing plate 25 to move downwards. Through the fixing block 32, the bottom ends of the two connecting rods 31 are driven away from each other, thereby causing the two buffer blocks 29 to move in opposite directions on the round rod 28. During this process, the buffer spring 30 is stretched, and the extension force of the buffer spring 30 plays a buffering role. As the two buffer blocks 29 move, the two push blocks 33 will apply compressive force to the two buffer frames 34. With the help of the mechanical principle of the arc structure, the arc can evenly distribute the pressure. Because the arc has the strongest compressive capacity in structural mechanics, through this design, when the climbing formwork frame body 13 falls, it can effectively reduce the impact force and provide the maximum shock absorption protection for the climbing formwork frame body.
