[0003] The climbing device in the prior art generally adopts a segmented lifting to raise the height of the tower construction machine, and it is necessary to manually build the column frame layer by layer. Since the position of the structure on the surface of the column frame used to fix the climbing device is fixed, the climbing device can only stop at a fixed position on the surface of each column frame during the climbing process, so that the climbing device can only stop at a fixed distance and position, and the adjustment performance is poor. In addition, the climbing device is mostly fixed by claws. When it has not climbed to the specified position, the climbing device cannot be fixed by the claws or a gap exists between the claws and the structure on the surface of the column frame.

DETAILED DESCRIPTION

[0023] like Figures 1 to 7 As shown, the present invention proposes a hydraulic power climbing device of a tower crane for tower construction, comprising a climbing device body 2 installed on a column frame 1, characterized in that the climbing device body 2 comprises a fixing device 21 and a telescopic cylinder 22, two fixing devices 21 are respectively arranged at the upper and lower ends of the telescopic cylinder 22, one of the fixing devices 21 is connected to the output shaft of the telescopic cylinder 22, and is installed on the climbing device body 2 and fixed to the lower side of the fixing device 21, while the output shaft 23 is connected to the upper end of the telescopic cylinder 22, and the sides of the fixing device 21 and the telescopic cylinder 22 are both provided with fixing devices for fixing each to the column frame 1, and the two fixing devices are arranged away from each other; The two fixing devices are respectively arranged around the fixing device 21 and the telescopic cylinder 22. When the climbing device is climbing, the two fixing devices are respectively embedded in the column frame 1 from the fixing device 21 and the telescopic cylinder 22. The fixing device comprises fixing devices 102 arranged in an array, the fixing devices 102 are provided with output ends extending outward, the output ends of all the fixing devices 102 are arranged toward the middle of the column frame 1, and the surface of the column frame 1 is provided with reinforcing ribs arranged in a vertical shape and at equal intervals, the reinforcing ribs and the surface of the column frame 1 form a cross-shaped structure, when the output ends of the fixing devices 102 are embedded in the column frame 1, the surfaces of the corresponding parts of the output ends of the fixing devices 102 and the cross-shaped structure are recessed inward; This solution innovatively adopts a double fixing device that is placed up and down, and drives the two fixing devices 21 to move alternately through the telescopic cylinder 22, so as to achieve continuous climbing instead of jumping step by step. Specifically, the fixing device 21 is embedded in the column frame on all sides instead of a single-point claw, forming a multi-point distributed support, and can be temporarily fixed by partial embedding even when it has not reached the specified position. In addition, the cross-shaped structure set on the surface of the column frame 1 matches the output end of the fixing device, and a mechanical interlock is formed through the recessed design, which significantly improves the shear resistance and lateral stability. This technical solution not only breaks through the limitations of the traditional docking position, but also solves the claw gap problem through an adaptive embedding mechanism, greatly improving the flexibility and safety of the climbing process.

[0024] Further, the two fixing devices 21 each include a frame 100, and a plurality of support wheels 101 are respectively provided on the upper and lower sides of the frame 100, which are against the surface of the column frame 1, and the adjacent ends of the two frames 100 are provided with connecting shafts 103, one of the frames 100 is connected to the end of the telescopic cylinder 22 through the connecting shaft 103 on its surface, and the other frame 100 is connected to the output shaft of the telescopic cylinder 22 through the connecting shaft 103 on its surface, so as to adjust the distance between the two frames 100 by driving the output shaft of the telescopic cylinder 22 to extend and retract; As shown above, by arranging multiple sets of support wheels 101 on the upper and lower sides of the frame, the device rolls and climbs along the surface of the column frame 1, greatly reducing friction loss and allowing dynamic adjustment of contact pressure. The distribution design of the support wheels 101 ensures that the load is evenly transmitted to the column frame 1 to avoid local stress concentration. At the same time, the frame 100 is linked with the telescopic cylinder 22 through the connecting shaft 103 to achieve precise control of the distance between the two frames: the output shaft of the telescopic cylinder 22 drives one frame to move, and the other frame remains fixed, alternating to form an "anchor-movement" cycle. This design not only simplifies the power transmission path, but also reduces the need for human intervention through mechanical linkage, making the climbing process more automated. In addition, the articulated structure of the connecting shaft 103 allows the frame to adapt to slight inclinations or unevenness of the frame surface during the climbing process, further improving the adaptability under complex working conditions. This technical solution significantly reduces energy consumption and improves climbing continuity through rolling contact and mechanical linkage.

[0025] In addition, the fixing device 102 includes an outer shell 021, a fixing block 022 and an airbag 023. The outer shell 021 has a plurality of movable grooves arrayed on its surface, each of which is provided with a fixing block 022. The fixing block 022 has a protruding layer 0221 protruding outward on its surface, and a slide groove 0211 for the protruding layer 0221 to slide is provided at the corresponding position between the outer shell 021 and the protruding layer 0221. The airbag 023 is provided on a side of the outer shell 021 away from the fixing block 022. The airbag 023 is connected to an external air compressor for air supply. When the airbag 023 is inflated, the fixing block 022 is pushed outward, so that the fixing block 022 is butted against the fixed reinforcing rib 12 on the surface of the column frame 1. Traditional claws need to be precisely aligned with the reinforcement ribs to lock, but this solution uses an inflatable airbag as a power source, and the airbag 023 expands to push the fixed block 022 outward to tighten the reinforcement ribs of the column frame. The raised layer 0221 on the surface of the fixed block 022 cooperates with the slide groove 0211 to ensure the linear motion trajectory and avoid skew jamming. When the airbag 023 is inflated, the fixed block 022 is embedded in the positioning groove formed by the reinforcement rib to form a multi-point distributed bite. Compared with the single-point claw fixation, the anti-overturning ability is significantly improved. In particular, the fixed block 022 is designed with a slot 0222 and a tooth row meshing structure, which realizes self-locking when in contact to prevent accidental disengagement caused by climbing vibration. In addition, the airbag 023 can be connected to an external air compressor to achieve rapid inflation and deflation, so that the fixing and release actions can be completed in seconds, greatly improving the climbing efficiency. The core advantage of this solution is that the combination of flexible driving airbags and rigid bite fixing blocks not only ensures the fixing strength, but also allows a certain degree of deformation compensation to adapt to the manufacturing tolerance and construction deformation of the column frame.

[0026] In addition, each fixing block 022 is provided with an inwardly recessed slot 0223 on one side close to the airbag 023, and a convex portion is provided at the corresponding position of the airbag 023 and each of the slots 0223, and the inner side of each convex portion is connected with the inner end of the airbag 023 through a 0232; This section further optimizes the power transmission efficiency between the airbag 023 and the fixed block 022, and achieves precise force application through the nested structure of the second card slot 0223 and the protrusion. The traditional airbag drive has the problem of uneven pressure distribution, which causes the fixed block 022 to move asynchronously. This solution sets a second card slot that is recessed inward on the inside of each fixed block, and designs a protrusion at the corresponding position of the airbag, so that when the airbag 023 expands, the protrusion will first fill the second card slot 0223, forming a "positioning first and then force application" mechanism. This design ensures that the pressure of the airbag 023 is concentrated on the center of gravity of the fixed block to avoid deflection caused by lateral force. At the same time, the protrusion is connected to the inside of the airbag 023 through a connecting pipe, so that the force of each fixed block is uniform. Even if the pressure of a single airbag unit fluctuates, the pressure distribution can be automatically balanced through the connecting pipe. The key to this technical solution is to convert the flexible expansion of the airbag into the rigid displacement of the fixed block, which not only retains the adaptability advantage of the airbag, but also eliminates the hidden danger of asynchronous multi-point drive, which is particularly suitable for high-precision climbing scenarios such as inclined tower construction.

[0027] Furthermore, the column frame 1 comprises a frame body 11 stacked up and down, and fixed reinforcement ribs 12 are symmetrically arranged on the surface of each frame body 11. There is a positioning groove between each fixed reinforcement rib 12 and the frame body 11. When the outer shell 021 is used for fixing, the fixing block 022 is embedded in each positioning groove; A T-shaped connection is formed between each fixed reinforcement rib 12 and the frame body 11 connected thereto.

[0028] The fixed block 022 is provided with an inwardly recessed slot 0222 on one side facing the fixed reinforcement rib 12, and a tooth row corresponding to the slot 0222 is provided on the surface of the fixed reinforcement rib 12. When the fixed block 022 abuts against the fixed reinforcement rib 12, the tooth row is embedded in the slot 0222, and when the fixed block 022 abuts against the fixed reinforcement rib 12, the tooth row is embedded in the slot 0222 to form a firm connection. This design enables the fixing device 21 to be firmly fixed at any position, not just limited to the fixed point. Through this connection method, the present invention not only improves the fixing effect of the fixing device 21, but also significantly improves the stability and safety of the construction. In addition, this design also enables the fixing device 21 to be flexibly adjusted at different positions, further improving the efficiency and flexibility of the construction.

[0029] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
