Improving the relocation efficiency of tower cranes is beneficial for increasing equipment utilization and reducing wind turbine installation costs. The climbing frame of the tower crane is the largest component in terms of overall size. During relocation, it usually needs to be disassembled, moved, and then reassembled, which is difficult, time-consuming, labor-intensive, and costly. In particular, the platforms around the climbing frame need to be disassembled one by one, and then reassembled manually with the assistance of cranes, making the operation complex, time-consuming, labor-intensive, and increasing labor intensity. Utility Model Content

[0003] The purpose of this application is to provide a climbing frame and tower crane to solve the problems of complex disassembly of the platform around the climbing frame in the prior art, which is time-consuming, labor-intensive and has a high labor intensity.

[0004] To achieve the above objectives, a first aspect of this application provides a climbing frame, comprising: The climbing frame body has at least two first hinge seats spaced apart along its width on its side. Each first hinge seat includes, along its height, an upper locking portion, a hinge portion, and a lower locking portion arranged sequentially. The climbing platform has at least two second hinge seats spaced apart from the first hinge seat along the width direction of the climbing frame body. The second hinge seats are hinged to the hinge portion of the first hinge seat. The climbing platform has a switchable working state and a folded state. In the working state, the support surface of the climbing platform is parallel to the horizontal plane, and the upper locking part is locked to the second hinge seat. In the folded state, the support surface of the climbing platform is perpendicular to the horizontal plane, and the lower locking part is locked to the second hinge seat.

[0005] As a further improvement to the above technical solution: In some embodiments, the second hinge seat includes: A support beam is provided at the bottom of the climbing platform and spans across the climbing platform; A first ear plate seat is disposed on the supporting crossbeam. In the working state, the first ear plate seat is used for locking engagement with the upper locking part; and The second ear plate seat is disposed on the side of the support beam opposite to the first ear plate seat. The second ear plate seat is hinged to the hinge part. In the folded state, the second ear plate seat is used to lock with the lower locking part.

[0006] In some embodiments, the upper locking part is provided with a first locking pin hole, and the first ear plate seat is provided with a corresponding second locking pin hole; In the working state, the first locking pin hole and the second locking pin hole are aligned, and a movable pin passes through the first locking pin hole and the second locking pin hole in sequence to lock the upper locking part and the second hinge seat.

[0007] In some embodiments, the hinge portion is provided with a hinge pin, the lower locking portion is provided with a third locking pin hole, and the second ear plate seat is provided with a U-shaped bayonet and a fourth locking pin hole; The U-shaped bayonet has its opening side facing downwards, and the hinge pin is housed within the U-shaped bayonet. In the folded state, the fourth locking pin hole is aligned with the third locking pin hole, and a movable pin passes through the third locking pin hole and the fourth locking pin hole in sequence to lock the lower locking part and the second hinge seat.

[0008] In some embodiments, the U-shaped bayonet is tilted.

[0009] In some embodiments, the angle between the extension direction of the U-shaped bayonet and the normal direction of the climbing platform is an acute angle.

[0010] In some embodiments, the climbing platform is further provided with a fence, and the fence is connected to the climbing platform by a locking assembly.

[0011] In some embodiments, the climbing platform is provided with a plurality of mounting seats around the perimeter corresponding to the fence, the fence is provided with uprights that cooperate with the mounting seats, and the lower end of the uprights is provided with a limiting pin and the locking assembly; The mounting base has a limiting notch and a limiting slot arranged sequentially from top to bottom along its length. The limiting notch has an opening and a limiting extension. The opening of the notch faces the inside of the climbing platform, and the limiting extension extends towards the climbing platform along the normal direction of the climbing platform. The limiting extension is used to accommodate the limiting pin. The limiting slot is an elongated hole, and the extension direction of the limiting slot is parallel to the extension direction of the limiting extension. The locking component passes through the limiting slot. When the locking component is not locked, it can slide relative to the limiting slot.

[0012] In some embodiments, the climbing platform is provided with raised kick plates around its perimeter, and the mounting base is disposed on the kick plates.

[0013] A second aspect of this application also provides a tower crane, including the climbing frame provided in the first aspect above.

[0014] Compared to existing technologies, the climbing frame and tower crane provided in this embodiment have at least the following beneficial effects, as detailed below: The climbing frame provided in this application connects the climbing platform to the main body of the climbing frame via a first hinge and a second hinge. The first hinge includes an upper locking part, a hinge part, and a lower locking part arranged sequentially along the height direction of the main body of the climbing frame. The climbing platform has a switchable working state and a folded state. In the working state, the support surface of the climbing platform is parallel to the horizontal plane, and the upper locking part is locked to the second hinge. In the folded state, the support surface of the climbing platform is perpendicular to the horizontal plane, and the lower locking part is locked to the second hinge. Thus, during disassembly and relocation, the locking connection between the second hinge and the upper locking part of the climbing platform can be released first, and then the climbing platform can be controlled to rotate downward around the hinge to switch to the folded state. Then, the second hinge and the lower locking part can be locked, thereby preventing the climbing platform from swaying relative to the main body of the climbing frame during transportation. Therefore, when the climbing frame provided in this application is moved to another location, it is not necessary to disassemble all the climbing platforms. The platforms can simply be folded and locked, and then unfolded to the working state and locked again when it is installed next time. The operation is simple and convenient, which greatly saves disassembly and assembly time, improves work efficiency, and reduces labor intensity.

[0018] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0019] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0020] Please see Figure 1 This embodiment provides a climbing frame that can be applied to tower cranes, especially tower cranes used in the field of wind power hoisting.

[0021] Please see Figure 1 , Figure 2 and Figure 3 The climbing frame provided in this embodiment includes a climbing frame body 100 and a climbing platform 300. The climbing frame body 100 is a truss structure with four sides, and each side can be configured with at least one climbing platform 300. The following description focuses on a climbing platform 300 in conjunction with the climbing frame body 100.

[0022] The side of the climbing frame body 100 is provided with at least two first hinge seats 200 at intervals along its width direction. The first hinge seat 200 includes an upper locking part 210, a hinge part 220 and a lower locking part 230 arranged sequentially along the height direction of the climbing frame body 100.

[0023] The climbing platform 300 has at least two second hinge seats 310 spaced apart from the first hinge seat 200 along the width direction of the climbing frame body 100. The second hinge seats 310 are hinged to the hinge portion 220 of the first hinge seat 200. The climbing platform 300 has a switchable working state and a folded state. In the working state, the support surface 301 of the climbing platform 300 is parallel to the horizontal plane, and the upper locking portion 210 is locked to the second hinge seat 310. In the folded state, the support surface 301 of the climbing platform 300 is perpendicular to the horizontal plane, and the lower locking portion 230 is locked to the second hinge seat 310.

[0024] Please see Figure 2 , Figure 10 and Figure 11 It is understandable that when the climbing platform 300 needs to be switched from the working state to the folded state, the locking connection of the upper locking part 210 to the climbing platform 300 is first released. At this time, the climbing platform 300 can flip downwards by its own gravity. When the support surface 301 of the climbing platform 300 is perpendicular to the horizontal plane, the lower locking part 230 can be locked to the second hinge seat 310 to complete the switch and realize the folding of the climbing platform 300.

[0025] When it is necessary to switch the climbing platform 300 from the folded state to the working state, that is, to unfold the climbing platform 300, first release the locking connection between the lower locking part 230 and the second hinge seat 310, then push the climbing platform 300 upward to a horizontal position, and then lock the upper locking part 210 and the second hinge seat 310, thereby completing the switch. When there are multiple climbing platforms 300, the above operation can be performed sequentially.

[0026] Please refer to the following: Figure 12In this way, during the relocation and dismantling of the tower crane, the locking connection between the second hinge seat 310 and the upper locking part 210 of the climbing platform 300 can be released first. Then, the climbing platform 300 can be controlled to rotate downward around the hinge part 220 to switch to the folded state. Then, the second hinge seat 310 can be locked to the lower locking part 230, thereby preventing the climbing platform 300 from swaying relative to the climbing frame body 100 during transportation. After that, the entire climbing frame can be laid down on the ground (all climbing platforms 300 on the side of the climbing frame body 100 in contact with the ground can be removed beforehand). Therefore, the climbing frame provided in this embodiment does not need to dismantle all climbing platforms 300 during relocation. It is only necessary to fold and lock the climbing platform 300. When installing it again, the climbing platform 300 can be unfolded to the working state and locked again. The operation is simple and convenient, which greatly saves dismantling and assembly time, improves work efficiency, and reduces labor intensity.

[0027] To more clearly describe the technical solution of this application, the climbing frame provided in this embodiment is described in detail below: Please see Figure 2 and Figure 4 The upper locking part 210, the hinge part 220, and the lower locking part 230 in the first hinge seat 200 are integrally constructed. The first hinge seat 200 has two side plates arranged in opposite positions. The space between the two side plates can accommodate the second hinge seat.

[0028] Please refer to the following: Figure 3 and Figure 5 The second hinge seat 310 includes a support beam 311, a first ear plate seat 312, and a second ear plate seat 313. The support beam 311 is disposed at the bottom of the climbing platform 300 and spans across the climbing platform 300. The first ear plate seat 312 is disposed on the support beam 311 and, in the working state, is used to lock into the upper locking part 210. The second ear plate seat 313 is disposed on the side of the support beam 311 opposite to the first ear plate seat 312 and is hinged to the hinge part 220. In the folded state, the second ear plate seat 313 is used to lock into the lower locking part 230.

[0029] Understandably, the support beam 311 serves two purposes: it supports the climbing platform 300 and it enhances the structural strength of the entire second hinge seat 310.

[0030] Optionally, the cross-section of the supporting beam 311 can be square, U-shaped, or I-shaped, etc. It should be understood that the above are merely illustrative examples and are not intended to limit the scope of protection of this application.

[0031] Please see Figure 2 , Figure 3 and Figure 4Furthermore, the upper locking part 210 is provided with a first locking pin hole 211, and the first ear plate seat 312 is provided with a corresponding second locking pin hole 3120; wherein, in the working state, the first locking pin hole 211 and the second locking pin hole 3120 are aligned, and a movable pin passes through the first locking pin hole 211 and the second locking pin hole 3120 in sequence to lock the connection between the upper locking part 210 and the second hinge seat 310.

[0032] The hinge portion 220 is provided with a hinge pin 221, the lower locking portion 230 is provided with a third locking pin hole 231, and the second ear plate seat 313 is provided with a U-shaped bayonet 3130 and a fourth locking pin hole 3131. The opening side of the U-shaped bayonet 3130 is arranged downward, and the hinge pin 221 is received in the U-shaped bayonet 3130. In the folded state, the fourth locking pin hole 3131 is aligned with the third locking pin hole 231, and a movable pin passes through the third locking pin hole 231 and the fourth locking pin hole 3131 in sequence to lock the lower locking portion 230 and the second hinge seat 310.

[0033] In this embodiment, the U-shaped latch 3130 is inclined. When the climbing platform 300 is in operation, the U-shaped latch 3130 is inclined towards one side of the climbing frame body 100, thus ensuring that it can effectively prevent it from coming out after being engaged with the hinge pin 221. At the same time, the U-shaped latch 3130 can be directly hooked onto the hinge pin 211, which is more convenient for disassembly and installation than a closed round hole.

[0034] In some embodiments, the angle between the extending direction of the U-shaped bayonet 3130 and the normal direction of the climbing platform 300 is an acute angle.

[0035] Please see Figure 2 , Figure 3 and Figure 5 In this embodiment, the outer perimeter of the climbing platform 300 is provided with fences 320, and the fences 320 and the climbing platform 300 are connected by locking components 323. Furthermore, in order to improve the transfer efficiency and avoid damage to the fences 320 and the large space occupied by the climbing platform 300 after folding, which would affect the transfer and transportation, the fences 320 and the climbing platform 300 can be set to be detachable and foldable.

[0036] Please refer to the following: Figure 6 and Figure 7Specifically, the climbing platform 300 is provided with several mounting seats 330 around the fence 320, and the fence 320 is provided with uprights 321 that cooperate with the mounting seats 330. The lower end of the uprights 321 is provided with a limit pin 322 and a locking component 323. The mounting base 330 is provided with a limiting notch 331 and a limiting slot 332 along its length direction from top to bottom. The limiting notch 331 has an opening 3310 and a limiting extension 3311. The opening of the opening 3310 faces the inside of the climbing platform 300. The limiting extension 3311 extends towards the climbing platform 300 along the normal direction of the climbing platform 300. The limiting extension 3311 is used to accommodate the limiting pin 322. The limiting slot 332 is an elongated hole and the extension direction of the limiting slot 332 is parallel to the extension direction of the limiting extension 3311. The locking component 323 is installed through the limiting slot 332. When the locking component 323 is not locked, it can slide relative to the limiting slot 332.

[0037] In some embodiments, the length of the limiting slot 332 is greater than or equal to the length of the limiting extension 3311. This facilitates the smooth disassembly and installation of the fence.

[0038] Please refer to the following: Figure 8 It is understandable that when the climbing platform 300 is in normal working condition, the guardrail 320 stands upright around the climbing platform 300 (e.g., Figure 5 and Figure 8 As shown), at this time, the limiting pin 322 at the lower end of the upright 321 is engaged in the limiting extension 3311 of the limiting notch 331, and the locking component 323 is in the locked state. The fence 320 is pulled down from the top and bottom. At the same time, the cooperation between the limiting extension 3311 and the limiting slot 332 can also limit the swing of the fence 320 relative to the mounting base 330, so as to improve the stability and safety of the fence 320.

[0039] Please refer to the following: Figure 9 When folding the fence 320: the locking component 323 can be adjusted to a relaxed, unlocked state. In this state, the locking component 323 can slide within the limiting slot 332. By lifting the entire fence 320, the limiting pin 322 on the upright 321 moves upward to the opening 3310 of the limiting notch 331. Then, the fence 320 is pushed towards the climbing platform 300. After the fence 320 falls onto the climbing platform 300, the locking component 323 is adjusted back to the locked state to restrict the movement of the fence 320 relative to the climbing platform 300. Furthermore, considering that the height of the fence 320 exceeds the height of the climbing platform 300, the fence 320 can be folded after the climbing platform 300 is switched to a folded state.

[0040] When unfolding the fence 320: first adjust the locking component 323 to the loose, unlocked state, straighten the fence 320 and insert it into the opening 3310 of the limiting notch 331, then push it into the limiting part of the limiting notch 331, and then adjust the locking component 323 to the locked state.

[0041] Thus, the fence 320 on the climbing platform 300 provided in this embodiment also has an unfolding and folding function, which further reduces the disassembly process during relocation, simplifies operation, improves relocation efficiency, and reduces the intensity of manual labor.

[0042] Please see Figure 3 and Figure 5 Furthermore, the climbing platform 300 is provided with raised kick plates 340 around its perimeter, and the mounting base 330 is mounted on the kick plates 340.

[0043] Optionally, the locking assembly 323 is an assembly in which a screw and a bolt cooperate. The screw can be a separate structure from the upright 321, or the screw can be welded to the upright 321.

[0044] Furthermore, this embodiment also provides a tower crane. The tower crane includes the climbing frame described above.
