[0002] Currently, self-erecting tower cranes are indispensable vertical transportation equipment in modern construction. As building heights continue to increase, tower cranes need to perform frequent climbing operations to meet construction needs.

[0003] Among them, a search revealed Chinese patent CN221343702U, which discloses a self-driven climbing conveyor for tower cranes. The above patent uses a structure of lifting mechanism and hook to realize the climbing function of the climbing conveyor on the tower crane. However, since the climbing conveyor is not easy to assemble on the tower crane, the use effect of the climbing device is not good. Therefore, in order to advance the industry's technology, better realize the function of climbing device assembly, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the structure and application method of the climbing device in the prior art. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing climbing conveyor devices are not convenient to assemble on tower cranes, resulting in poor performance of the climbing devices, and proposes a self-elevating modular climbing device for tower cranes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Each climbing module component consists of two sets of climbing components, a hydraulic lift, and a limiting component. Each climbing component includes a main frame, with connecting end frames fixedly connected to the top and bottom of the main frame. One end plate is fixedly connected to one end of the connecting end frame, and connecting plates are fixedly connected to both sides of the main frame. The two ends of the connecting plates are respectively fixedly connected to the end plates. The hydraulic lift is fixed between the end plates of the two sets of climbing components by bolts. The limiting component includes a fixing frame, which is welded to one side of the main frame. A hydraulic cylinder is fixedly connected to one side of the fixing frame. One end of the hydraulic rod of the hydraulic cylinder is fixedly connected to a side plate, and two limiting sliders are fixedly connected to one side of the side plate. The limiting sliders are slidably inserted into the fixing frame.

[0007] Furthermore, connecting bolts are inserted between the two opposing main frames and between the two connecting end frames, and nuts are threaded onto both ends of the connecting bolts.

[0008] Furthermore, one side of the connecting plate is provided with multiple slots, and one side of the connecting plate is integrally formed with multiple locking blocks, and the locking blocks of the two climbing components engage with the slots.

[0009] Furthermore, a plurality of connecting ribs are fixedly connected to one side of the end plate, and the other end of the connecting ribs is fixedly connected to the connecting end frame.

[0010] Furthermore, multiple fixing ribs are fixedly connected to the top inner wall and bottom inner wall of the main frame, and one side of the fixing rib is fixedly connected to one side of the main frame.

[0011] Furthermore, an anti-slip groove is provided on one side of the limiting slider.

[0012] Furthermore, the top and bottom inner walls of the main frame are rotatably connected with multiple climbing wheels.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By placing two sets of climbing module components on both sides of the tower crane frame, then passing connecting bolts between the two sets of climbing module components, and then tightening the nuts, the two sets of climbing module components can be quickly fixed to both sides of the tower crane frame, thereby improving the effectiveness of the climbing device.

[0015] 2. By moving the side plate under the drive of the hydraulic cylinder, the limit slider is moved, thereby causing the two limit sliders to lock onto the tower crane frame, thus fixing the tower crane climbing body so that the tower crane climbing body can continue to climb.

[0016] 3. By engaging the locking block of one climbing module component with the locking slot of another climbing module component, the two climbing module components can be assembled together, thereby pre-installing the two climbing module components and improving installation efficiency.

The hydraulic lift 4 is fixedly connected to the end plate 303 respectively. It is fixed between the end plates 303 of the two sets of climbing components 3 by bolts. The hydraulic lift 4 is used to make the tower crane climbing body 1 climb upward. Connecting bolts 6 are inserted between the two opposite main frames 301 and between the two connecting end frames 302. Nuts are threaded on both ends of the connecting bolts 6. The connecting bolts 6 are passed through the two sets of climbing module components 2 and the nuts are tightened to fix the two sets of climbing module components 2 to both sides of the tower crane frame.

One end of the hydraulic rod of the hydraulic cylinder 502 is fixed to a side plate 503 by bolts. Two limiting sliders 504 are welded to one side of the side plate 503. The limiting sliders 504 are slidably inserted into the fixing frame 501. Under the drive of the hydraulic cylinder 502, the side plate 503 moves, thereby driving the limiting sliders 504 to move, so that the two limiting sliders 504 are locked on the tower crane frame, thereby fixing the tower crane climbing body 1.

[0030] Multiple slots 7 are provided on one side of the connecting plate 305, and multiple locking blocks 8 are integrally formed on one side of the connecting plate 305. The locking blocks 8 of the two climbing components 3 are engaged with the slots 7, and the locking blocks 8 of one climbing module component 2 are engaged with the slots 7 of the other climbing module component 2, so that the two climbing module components 2 are assembled together.

Multiple fixing ribs 10 are welded on the top inner wall and the bottom inner wall of the main frame 301, and one side of the fixing ribs 10 is fixedly connected to one side of the main frame 301, so as to improve the strength of the main frame 301. An anti-slip groove is provided on one side of the limiting slider 504. Multiple climbing wheels 304 are rotatably connected to the top inner wall and the bottom inner wall of the main frame 301.

Next, the hydraulic lift 4 is used to make the tower crane climbing body 1 climb upward. At the same time, the climbing wheel 304 rolls along the tower crane frame, thereby making the climbing body 1 of the tower crane stable. After that, the hydraulic cylinder 502 is activated. Under the drive of the hydraulic cylinder 502, the side plate 503 moves, thereby driving the limit slider 504 to move, so that the two limit sliders 504 are locked on the tower crane frame, thereby fixing the tower crane climbing body 1.
