The hydraulic component specifically includes a cylinder block, a jacking piston, a jacking piston rod, a lifting piston, a lifting piston rod, and a partition layer.

[0052] Such as Figure 1 、 Figure 3 and Figure 4As shown in the figure, the present application provides a hydraulic system for a climbing formwork device, which includes a hydraulic component 1, a jacking seat 2, and a lifting seat 3. The hydraulic component 1 specifically includes a cylinder block 11, a jacking piston 12, a jacking piston rod 13, a lifting piston 14, a lifting piston rod 15, and a partition layer 16. Among them, the partition layer 16 is fixedly arranged in the cylinder block 11 and divides the interior of the cylinder block 11 into an upper oil chamber and a lower oil chamber. The jacking piston 12 is arranged in the upper oil chamber and further divides the upper oil chamber into a jacking upper oil chamber 111 and a jacking lower oil chamber 112; the lifting piston 14 is arranged in the lower oil chamber and divides the lower oil chamber into a lifting upper oil chamber 113 and a lifting lower oil chamber 114. One end of the jacking piston rod 13 is connected to the jacking piston 12, and the other end extends above the cylinder block 11; one end of the lifting piston rod 15 is connected to the lifting piston 14, and the other end extends below the cylinder block 11. In addition, the hydraulic component 1 also includes conventional components such as hydraulic pipelines, hydraulic pumps, and control valves. Although these components are not further described in detail and are not shown in the drawings, these conventional components are undoubtedly essential components of the hydraulic system. Therefore, these components all fall within the protection scope of the present application.

[0053] The jacking seat 2 is sleeved above the cylinder block 11 and is connected to the extending end of the jacking piston rod 13. At the same time, the jacking seat 2 is fixedly connected to the upper climbing formwork frame 8 of the climbing formwork device. The lifting seat 3 is sleeved below the cylinder block 11 and is connected to the extending end of the lifting piston rod 15. At the same time, the lifting seat 3 is fixedly connected to the lower climbing formwork frame 9 of the climbing formwork device.

[0054] During the working process, the hydraulic system first injects hydraulic oil into the jacking lower oil chamber 112, and at the same time pumps out the hydraulic oil in the jacking upper oil chamber 111, driving the jacking piston 12 and the jacking piston rod 13 to move upward, thereby pushing the jacking seat 2 to climb upward. When the jacking seat 2 climbs to a predetermined position, the hydraulic oil in the jacking lower oil chamber 112 is pumped out by adjusting the control valve, and hydraulic oil is injected into the jacking upper oil chamber 111. At the same time, hydraulic oil is injected into the lifting upper oil chamber 113, and the hydraulic oil in the lifting lower oil chamber 114 is pumped out to drive the entire cylinder block 11 to lift upward. Finally, the hydraulic oil in the lifting upper oil chamber 113 is pumped out by adjusting the control valve, and hydraulic oil is injected into the lifting lower oil chamber 114, thereby driving the lifting seat 3 to lift upward and completing the climbing process of the climbing formwork device.

[0055] The hydraulic system of the climbing formwork device in this application integrates the jacking and lifting functions within a single cylinder block 11, simplifying the complex structure of the multi-cylinder block collaborative work in the traditional hydraulic system. This not only reduces the number of components in the hydraulic system but also lowers the difficulty of installation and maintenance. At the same time, it improves the reliability and operation efficiency of the system. In addition, by reasonably arranging the oil cavities and control valves, precise control during the climbing process is achieved, further enhancing the safety and stability of construction. Compared with the hydraulic system of the traditional climbing formwork device, the hydraulic system provided in this application has the advantages of compact structure, simple operation, and reliable work.

[0056] As Figure 4 shown, in a specific embodiment of this application, the jacking seat 2 includes a jacking sleeve part 21, which extends downward along the axis direction of the hydraulic component 1 to form a cylindrical structure. The upper end part of the cylinder block 11 is nested within the jacking sleeve part 21, so that a stable sliding fit relationship is formed between the jacking seat 2 and the cylinder block 11. This design not only ensures the vertical movement accuracy of the jacking seat 2 under hydraulic drive but also enhances the rigidity and stability of the overall structure. At the same time, the inner wall of the jacking sleeve part 21 and the outer wall of the cylinder block 11 are sealed by appropriate seals to prevent hydraulic oil leakage, thus ensuring the efficient operation of the hydraulic system.

[0057] As Figure 4 shown, the lifting seat 3 includes a lifting sleeve part 31, which extends upward along the axial direction of the hydraulic component 1 and also forms a cylindrical structure. The lower end part of the cylinder block 11 is nested within the lifting sleeve part 31, so that a similar sliding fit relationship is formed between the lifting seat 3 and the cylinder block 11. The inner wall of the lifting sleeve part 31 and the outer wall of the cylinder block 11 are also sealed by seals to ensure the sealing performance of the hydraulic system. The design of the lifting sleeve part 31 enables the lifting seat 3 to move smoothly along the axis direction of the cylinder block 11 under hydraulic drive, thereby realizing the climbing function of the climbing formwork device.

[0058] As Figure 5 shown, in a specific embodiment of this application, the hydraulic system of the climbing formwork device further includes a first anti-falling structure 22, which is used to prevent the jacking seat 2 from accidentally falling relative to the cylinder block 11 during the operation of the hydraulic system. The first anti-falling structure 22 includes a first anti-falling clamping groove 221 provided on the inner wall of the jacking sleeve part 21. The number of the first anti-falling clamping grooves 221 is multiple, and each first anti-falling clamping groove 221 is arranged in sequence along the axial direction of the jacking sleeve part 21 to form a series of clamping points, so as to provide multi-level anti-falling protection for the jacking seat 2 and ensure its reliable anti-falling function at any height position.

[0059] As Figure 5As shown, the first anti-falling structure 22 also includes a first anti-falling base 222, a first abutment 223 and a telescopic drive 224. The first anti-falling base 222 is fixedly mounted on the upper cover plate of the cylinder body 11, and a first accommodating groove 2221 is provided inside the first abutment 223 for accommodating the first abutment 223. The lower end of the first abutment 223 is connected to the first anti-falling base 222 by a hinged manner, so that the first abutment 223 can rotate in the first accommodating groove 2221. The upper end of the first abutment 223 can be retracted into the first accommodating groove 2221 or supported outwardly in the first anti-falling groove 221, thereby realizing the locking or release between the jacking seat 2 and the cylinder body 11. One end of the telescopic drive 224 is connected to the first anti-falling base 222, and the other end is drivingly connected to the first abutment 223 to control the motion state of the first abutment 223. The telescopic drive 224 can be specifically an electric elastic spring, etc.

[0060] When the lifting piston rod 13 pushes the lifting seat 2 to move upward, the telescopic driving member 224 drives the first locking member 223 to retract into the first accommodating groove 2221, so that the lifting seat 2 can be freely lifted and lowered along the cylinder body 11; when the hydraulic system has an abnormality or emergency braking is required, the telescopic driving member 224 drives the first locking member 223 to extend outward and be locked into the first anti-falling groove 221, thereby preventing the lifting seat 2 from falling and ensuring construction safety.

[0061] like Figure 4 As shown, in a specific embodiment of the present application, the lifting seat 2 further includes a conduit portion 23, which is arranged at the lower end of the lifting sleeve portion 21 and extends downward along the axial direction of the hydraulic assembly 1. The conduit portion 23 is a cylindrical structure, and its inner diameter is slightly larger than the outer diameter of the cylinder body 11, so that the conduit portion 23 can be sleeved on the outside of the cylinder body 11 and form a sliding fit relationship with the cylinder body 11. This design not only provides additional guiding support for the lifting seat 2, but also enhances the stability and centering of the lifting seat 2 during movement, thereby effectively reducing the deflection or shaking that may occur during the lifting process. The inner wall of the conduit portion 23 and the outer wall of the cylinder body 11 are matched with an appropriate clearance to ensure that the lifting seat 2 can slide smoothly along the axial direction of the cylinder body 11.

[0062] like Figure 4As shown, in a specific embodiment of the present application, the jacking seat 2 further includes a buffer pad 24. The buffer pad 24 is disposed at the lower end of the conduit portion 23 and is used to provide buffer protection when the jacking seat 2 falls uncontrollably, thereby reducing or avoiding damage to the equipment and surrounding structures caused by the fall. The buffer pad 24 is made of a material with high elasticity and high impact resistance, such as rubber or polyurethane composite material, and can effectively absorb and disperse the impact energy generated during the falling process. The buffer pad 24 is fixed to the lower end of the conduit portion 23 by fasteners or bonding to ensure its stable installation position and performance during long-term use.

[0063] When the jacking seat 2 moves up and down along the cylinder block 11 under the normal working state of the hydraulic system, a certain gap is maintained between the buffer pad 24 and the cylinder block 11 or other adjacent components to avoid unnecessary friction or interference. However, once the hydraulic system malfunctions or the jacking seat 2 falls uncontrollably due to an accident, the buffer pad 24 will contact the underlying support structure or limiting device, and absorb the impact force through its elastic deformation, thereby slowing down the falling speed and reducing the impact intensity. This design can not only effectively protect the jacking seat 2 and its related components from damage, but also reduce the potential impact on the construction environment and surrounding equipment, further improving construction safety and equipment reliability.

[0064] As Figure 1 and Figure 2 shown, the present application also provides a climbing formwork device, including the hydraulic system in the above embodiment. Therefore, it also has the advantages of the hydraulic system in the above embodiment.

[0065] In a specific embodiment of the present application, the climbing formwork device further includes a climbing structure. The climbing structure includes a wall-hanging base 4 and a climbing slide rail 5. The number of wall-hanging bases 4 is multiple, and each wall-hanging base 4 is fixedly connected to the exterior wall foundation at intervals along the climbing direction to form continuous support points. Each wall-hanging base 4 is provided with a guide groove 41 for guiding the movement direction of the climbing slide rail 5. The climbing slide rails 5 are respectively connected to the jacking seat 2 and the lifting seat 3 of the hydraulic system. The hydraulic system drives the movement of the jacking seat 2 and the lifting seat 3, indirectly driving the climbing slide rails 5 to slide unidirectionally along the climbing direction on the guide grooves 41, thereby realizing the climbing function of the climbing formwork device.

[0066] When installing the wall-mounted base 4, the construction workers are located on the lower climbing formwork 9. First, embedment parts are driven into the already cast and solidified concrete exterior wall, and then the wall-mounted base 4 is firmly connected to the embedment parts through high-strength bolts. The installation distances between the wall-mounted bases 4 need to strictly conform to the climbing distance limit of the climbing formwork device to ensure the smoothness and safety of the climbing process. The specific structure of the wall-mounted base 4 can adopt a C-shaped steel, and its guide groove 41 is the hollow groove of the C-shaped steel, which can provide a stable sliding channel for the crawling slide rail 5. The specific structure of the crawling slide rail 5 can adopt a T-shaped steel. The vertical ends of the T-shaped steel are respectively connected to the jacking seat 2 and the lifting seat 3 of the hydraulic system, and the horizontal end of the T-shaped steel is embedded in the guide groove 41 of the wall-mounted base 4 and slides unidirectionally along the guide groove 41 under the drive of the hydraulic system.

[0067] As Figure 6 and Figure 8 shown, in a specific embodiment of the present application, the climbing formwork device further includes a second anti-falling structure 6 for preventing the crawling slide rail 5 from falling relative to the wall-mounted base 4 during movement. The second anti-falling structure 6 includes a second anti-falling card slot 61, a second clamping member 62, and a first elastic member 63. The second anti-falling card slot 61 is arranged on the crawling slide rail 5 and is spaced along its length direction to form a plurality of clamping points. The second clamping member 62 is arranged on the wall-mounted base 4 and is connected to the wall-mounted base 4 in a hinged manner. The wall-mounted base 4 is also provided with a second accommodating groove for accommodating the second clamping member 62 in a non-locked state. One end of the first elastic member 63 is connected to the second clamping member 62, and the other end is fixedly connected to the wall-mounted base 4 for providing an elastic reset force for the second clamping member 62. The first elastic member 63 can specifically be a spring.

[0068] When the crawling slide rail 5 slides unidirectionally along the crawling direction on the guide groove 41, the second clamping member 62 is pressed into the second accommodating groove under the push of the crawling slide rail 5, so that the crawling slide rail 5 can slide smoothly. When the crawling slide rail 5 stops moving or the hydraulic system malfunctions, the first elastic member 63 drives the second clamping member 62 to pop out of the second accommodating groove and abut against the second anti-falling card slot 61, thereby preventing the crawling slide rail 5 from falling.

[0069] In another specific embodiment of the present application, the design of the second anti-falling structure 6 can be adjusted adaptively. Specifically, the second anti-falling card slot 61 can be arranged on the wall-hanging base 4, and the second abutting member 62 is arranged on the crawling slide rail 5. A second accommodating groove is provided on the crawling slide rail 5 for accommodating the second abutting member 62 in the non-locked state. The second abutting member 62 is connected to the crawling slide rail 5 by a hinge. One end of the first elastic member 63 is connected to the second abutting member 62, and the other end is fixedly connected to the crawling slide rail 5. When the crawling slide rail 5 slides along the guide groove 41, the second abutting member 62 is pressed into the second accommodating groove; when the crawling slide rail 5 stops moving, the first elastic member 63 drives the second abutting member 62 to pop out and abut against the second anti-falling card slot 61, thereby realizing the anti-falling function.

[0070] As Figure 7 and Figure 8 shown, in a specific embodiment of the present application, the climbing formwork device further includes a third anti-falling structure 7 for further preventing the crawling slide rail 5 from falling relative to the wall-hanging base 4 during movement. The third anti-falling structure 7 includes a second anti-falling base 71, a third abutting member 72, a limiting member 73, and a second elastic member 74. The second anti-falling base 71 is fixedly connected to the crawling slide rail 5, and a third accommodating groove 711 is provided inside it for accommodating the third abutting member 72. The third abutting member 72 is connected to the second anti-falling base 71 by a hinge and can rotate in the third accommodating groove 711. The limiting member 73 is arranged above the third abutting member 72 for limiting the upper limit position of the rotation of the third abutting member 72 to prevent it from rotating excessively. One end of the second elastic member 74 is connected to the second anti-falling base 71, and the other end is connected to the lower end of the third abutting member 72 to provide an elastic reset force for the third abutting member 72.

[0071] When the crawling slide rail 5 slides unidirectionally along the crawling direction on the guide groove 41, the third abutting member 72 is pressed into the third accommodating groove 711 under the push of the crawling slide rail 5, so that the crawling slide rail 5 can slide smoothly. When the crawling slide rail 5 stops moving and the third abutting member 72 passes over the top of the wall-hanging base 4, the second elastic member 74 drives the third abutting member 72 to pop out from the third accommodating groove 711 and abut against the top of the wall-hanging base 4, thereby preventing the crawling slide rail 5 from falling.

[0072] As Figure 1 and Figure 2As shown, in a specific embodiment of the present application, the climbing formwork device further includes an upper climbing formwork frame 8 and a lower climbing formwork frame 9. The upper climbing formwork frame 8 is fixedly connected to the jacking seat 2 of the hydraulic system through a connecting member. Its structure mainly includes a formwork support bottom plate, a telescopic formwork support displacement rod, a formwork support, and a formwork. The formwork support bottom plate serves as the basic load-bearing component of the upper climbing formwork frame 8, which is used to bear the overall weight of the formwork system and evenly transfer it to the jacking seat 2. The telescopic formwork support displacement rod is arranged on the formwork support bottom plate and drives the formwork support to move horizontally through hydraulic or mechanical drive means to meet the formwork requirements in different construction stages. The formwork support is connected to the formwork and is used to support and fix the formwork to ensure the smooth progress of the formwork operation for the concrete wall surface. In addition, the upper climbing formwork frame 8 is also provided with a guardrail to provide a safe working environment for construction workers. Workers can carry out concrete pouring, formwork adjustment, and the climbing operation of the climbing formwork device on the upper climbing formwork frame 8.

[0073] The lower climbing formwork frame 9 is fixedly connected to the lifting seat 3 of the hydraulic system through a connecting member. Its structural design mainly focuses on the integration of the auxiliary functions of the hydraulic system. The lower climbing formwork frame 9 is provided with an oil delivery and monitoring device, which includes components such as an oil delivery pipeline, an oil pump, a control valve, and a displacement sensor. The oil delivery pipeline is connected to the cylinder block 11 of the hydraulic system and is used to deliver or discharge hydraulic oil to the jacking upper oil chamber 111, the jacking lower oil chamber 112, the lifting upper oil chamber 113, and the lifting lower oil chamber 114, so as to drive the movement of the jacking piston 12 and the lifting piston 14. The displacement sensor is arranged at key positions of the lower climbing formwork frame 9 and is used to monitor the overall climbing displacement of the climbing formwork frame in real time and feed the data back to the control system to ensure the accuracy and safety of the climbing process.

[0074] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
