Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic climbing formwork, specifically a hydraulic climbing formwork frame used for the construction of high bridge piers. Background Technology
[0002] Climbing formwork, also known as scaffolding formwork, consists of three parts: climbing formwork, climbing scaffolding (some climbing formwork does not have a climbing scaffolding), 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 it has self-climbing capabilities, it does not require lifting machinery, which reduces the workload of transportation machinery during construction.
[0003] In existing technologies, a reversing pawl is connected or disconnected from the slide rail, and a hydraulic system drives the reversing pawl to move, pushing the slide rail to adjust its height, thus achieving alternating lifting of the climbing scaffold and the guide rail. During the ascent of the climbing scaffold and formwork, the weight of the climbing scaffold is concentrated on the reversing pawl, leading to severe wear on the pawl. This may cause damage to the reversing pawl, causing the wall-mounted device to fall and resulting in a safety accident.
[0004] Therefore, a hydraulic climbing formwork for the construction of high bridge piers is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a hydraulic climbing formwork for the construction of high bridge piers.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A hydraulic climbing formwork for high bridge pier construction, comprising a wall-attaching device; a hydraulic cylinder is provided on the side of the wall-attaching device, and a reversing pawl is provided at the output end of the hydraulic cylinder; a guide rail is slidably connected to the left side of the wall-attaching device, and a stop block is fixedly connected to the right side of the guide rail; a bidirectional cylinder is provided on the side of the wall-attaching device, and a limiting toothed plate is fixedly connected to the output end of the bidirectional cylinder; the limiting toothed plate is slidably connected to the wall-attaching device; a limiting groove is provided on the inner side of the stop block. A rack is fixedly connected inside the limiting groove, and the limiting tooth plate works in conjunction with the rack. A template is provided on the top of the wall-mounted device. In this step, when the guide rail moves, it drives the rack inside the limiting groove to move. After the guide rail stops moving, the bidirectional cylinder can push the limiting tooth plates on both sides to move, so that the limiting tooth plates are inserted into the limiting groove and connected to the rack, limiting the guide rail again. This relieves the pressure of the reversing pawl connecting with the stop block, preventing the reversing pawl from wearing out after prolonged use and causing damage when connecting with the stop block, thus reducing the probability of the wall-mounted device falling.
[0007] Preferably, a connecting block is fixedly connected to the right side of the limiting toothed plate. A groove is formed inside the connecting block, and a limiting plate is slidably connected inside the groove. A spring is fixedly connected to the inner side of the groove, and one end of the spring is fixedly connected to the limiting plate. The limiting plate works in conjunction with the stop block. In this step, the connecting block drives the limiting plate to insert into the inner side of the stop block, which can support the inner side of the stop block. When the guide rail becomes loose and moves downward, the top of the limiting plate can support the bottom surface of the stop block, sharing the weight borne by the limiting toothed plate when connected to the rack, and can limit the stop block again.
[0008] Preferably, a protective sleeve is fixedly connected to the surface of the bidirectional cylinder, and the protective sleeve is slidably connected to the wall-mounting device; this step uses the protective sleeve to limit and protect the surface of the wall-mounting device, preventing impurities such as concrete from affecting the bidirectional cylinder and causing wear and impact.
[0009] Preferably, a connecting piece is fixedly connected to the surface of the protective sleeve, and the connecting piece is threadedly connected to the wall-mounting device by a number of bolts; this step, by setting the connecting piece, can separate the connecting piece from the wall-mounting device by rotating the bolts on the surface of the connecting piece, and disassemble and assemble the connecting piece and the protective sleeve, so as to disassemble and repair the bidirectional cylinder.
[0010] Preferably, the limiting plate has an L-shaped structure, and one end of the limiting plate is located inside the groove; this step, by setting the limiting plate to an L-shaped structure, ensures that one side of the limiting plate is always located inside the groove, thereby limiting the distance the limiting plate can move.
[0011] Preferably, the bottom of the limiting plate is provided with a guide cut, and the guide cut is used in conjunction with the stop block; in this step, when the guide rail drives the stop block to move upward, the stop block at the bottom of the limiting plate will contact the guide cut when it moves upward, and push the limiting plate to move inward into the groove, so as to prevent the position of the limiting plate from affecting the upward movement of the stop block. When the stop block passes the limiting plate, the spring can continue to push the limiting plate to reset.
[0012] The advantages of this utility model are:
[0013] 1. The hydraulic climbing formwork frame for high bridge pier construction described in this utility model, when the guide rail moves, drives the rack inside the limiting groove to move. After the guide rail stops moving, the bidirectional cylinder can push the limiting tooth plates on both sides to move, so that the limiting tooth plates are inserted into the limiting groove and connected to the rack, limiting the guide rail again. This relieves the pressure of the reversing pawl connecting with the stop block, prevents the reversing pawl from wearing out after a long period of use, and reduces the probability of the wall-mounted device falling.
[0014] 2. The hydraulic climbing formwork frame for high bridge pier construction described in this utility model uses a connecting block to drive a limiting plate to insert into the inner side of a stop block, which can support the inner side of the stop block. When the guide rail becomes loose and moves downward, the top of the limiting plate can support the bottom surface of the stop block, share the weight borne when the limiting tooth plate is connected to the toothed rack, and can limit the stop block again.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 5As shown, a hydraulic climbing formwork for bridge pier construction includes a wall-mounted device 1. A hydraulic cylinder 12 is mounted on the side of the wall-mounted device 1, and a reversing pawl 13 is mounted on the output end of the hydraulic cylinder 12. A guide rail 14 is slidably connected to the left side of the wall-mounted device 1, and a stop block 15 is fixedly connected to the right side of the guide rail 14. A bidirectional cylinder 16 is mounted on the side of the wall-mounted device 1, and a limiting toothed plate 17 is fixedly connected to the output end of the bidirectional cylinder 16. The limiting toothed plate 17 is slidably connected to the wall-mounted device 1. A limiting groove 18 is formed on the inner side of the stop block 15, and a rack 19 is fixedly connected inside the limiting groove 18. The limiting toothed plate 17 and the rack 19 cooperate with each other. A template 110 is mounted on the top of the wall-mounted device 1. During operation, when the reversing pawl 13 rotates and connects with the stop block 15, the guide rail 14 is positioned. When a secondary fixation of the guide rail 14 is required, the bidirectional cylinder 16 drives the limiting toothed plates 17 on both sides to limit their positions to both sides. The groove 18 moves, causing the limiting toothed plate 17 to insert into the limiting groove 18 and connect with the rack 19. When the height of the guide rail 14 needs to be adjusted, the limiting toothed plate 17 separates from the limiting groove 18 and connects with the stop block 15 through the reversing pawl 13. The reversing pawl 13 is driven to move by the hydraulic cylinder 12. At this time, the reversing pawl 13 can drive the stop block 15 to move the guide rail 14 to adjust the height. In this step, when the guide rail 14 moves, it drives the rack 19 on the inside of the limiting groove 18 to move. After the guide rail 14 stops moving, the bidirectional cylinder 16 can push the limiting toothed plates 17 on both sides to move, so that the limiting toothed plates 17 insert into the limiting groove 18 and connect with the rack 19, limiting the guide rail 14 again. This relieves the pressure of the reversing pawl 13 connecting with the stop block 15, preventing the reversing pawl 13 from being severely worn after long-term use, which could lead to damage when the reversing pawl 13 connects with the stop block 15, and reducing the probability of the wall-mounted device 1 falling.
[0024] like Figures 2 to 5 As shown, a connecting block 21 is fixedly connected to the right side of the limiting tooth plate 17. A groove 22 is provided inside the connecting block 21, and a limiting plate 23 is slidably connected inside the groove 22. A spring 24 is fixedly connected to the inner side of the groove 22, and one end of the spring 24 is fixedly connected to the limiting plate 23. The limiting plate 23 cooperates with the stop block 15. During operation, when the limiting tooth plate 17 moves, it drives the connecting block 21 to move. The connecting block 21 then drives the limiting plate 23 and the spring 24 to move. The spring 24 can push the limiting plate 23 towards the stop blocks 15 on both sides. When the limiting tooth plate 17 inserts... When the guide rail 14 moves the stop block 15 upward, the limit plate 23 can be inserted between the stop blocks 15. When the guide rail 14 moves the stop block 15 upward, the limit tooth plate 17 moves the connecting block 21 towards the center, so that the limit plate 23 moves out of the inside of the stop block 15. This step, through the connecting block 21, moves the limit plate 23 into the inside of the stop block 15, which can support the inside of the stop block 15. When the guide rail 14 becomes loose and moves downward, the top of the limit plate 23 can support the bottom surface of the stop block 15, share the weight borne by the limit tooth plate 17 and the rack 19 when they are connected, and can limit the stop block 15 again.
[0025] like Figures 3 to 5 As shown, a protective sleeve 31 is fixedly connected to the surface of the bidirectional cylinder 16, and the protective sleeve 31 is slidably connected to the wall-mounting device 1. During operation, the wall-mounting device 1 moves, driving the protective sleeve 31 to move. This step can limit and protect the surface of the wall-mounting device 1 through the protective sleeve 31, preventing impurities such as concrete from affecting the bidirectional cylinder 16 and causing wear and impact.
[0026] like Figure 4 As shown, a connecting piece 41 is fixedly connected to the surface of the protective sleeve 31. The connecting piece 41 is threadedly connected to the wall-mounted device 1 by several bolts. In this step, by setting the connecting piece 41 and rotating the bolts on the surface of the connecting piece 41, the connecting piece 41 can be separated from the wall-mounted device 1, and the connecting piece 41 and the protective sleeve 31 can be disassembled and assembled so as to disassemble and repair the bidirectional cylinder 16.
[0027] like Figure 5 As shown, the limiting plate 23 has an L-shaped structure, and one end of the limiting plate 23 is located inside the groove 22. This step, by setting the limiting plate 23 to an L-shaped structure, ensures that one side of the limiting plate 23 is always located inside the groove 22, thereby limiting the distance that the limiting plate 23 can move.
[0028] like Figure 5 As shown, the bottom of the limiting plate 23 has a guide cutout, which is used in conjunction with the stop block 15. In this step, when the guide rail 14 moves the stop block 15 upward, the stop block 15 at the bottom of the limiting plate 23 will contact the guide cutout when it moves upward, and push the limiting plate 23 to move inward into the groove 22 to prevent the position of the limiting plate 23 from affecting the upward movement of the stop block 15. When the stop block 15 passes the limiting plate 23, the spring 24 can continue to push the limiting plate 23 to reset.
[0029] Working principle: When the reversing pawl 13 rotates and connects with the stop block 15, the guide rail 14 is positioned. When secondary fixing of the guide rail 14 is required, the bidirectional cylinder 16 drives the limiting tooth plates 17 on both sides to move into the limiting grooves 18 on both sides, so that the limiting tooth plates 17 are inserted into the limiting grooves 18 and connected to the rack 19. When the height of the guide rail 14 needs to be adjusted, the limiting tooth plates 17 separate from the limiting grooves 18 and connect with the stop block 15 through the reversing pawl 13. The hydraulic cylinder 12 drives the reversing pawl 13 to move. At this time, the reversing pawl 13 can drive the stop block 15 to move the guide rail 14 to adjust the height. When the limiting tooth plates 17 move, they drive the connecting block 21 to move. The connecting block 21 drives the limiting plate 23 and the spring 24 to move. The spring 24 can push the limiting plate 23 to move towards the stops 15 on both sides. When the limiting tooth plate 17 is inserted into the limiting groove 18, the limiting plate 23 can be inserted between the stops 15. When the guide rail 14 drives the stops 15 to move upward, the stops 15 at the bottom of the limiting plate 23 will contact the guide cut when moving upward, and push the limiting plate 23 to move towards the inside of the groove 22, so that the limiting plate 23 moves out of the inside of the stops 15. When the wall-mounted device 1 moves, it drives the protective sleeve 31 to move. Rotating the bolts on the surface of the connecting piece 41 can separate the connecting piece 41 from the wall-mounted device 1, and the connecting piece 41 and the protective sleeve 31 can be disassembled and assembled.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
