Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to a tower crane climbing structure and a tower crane. Background Technology

[0002] As market demand for lifting equipment increases, the size of tower crane towers is gradually increasing. The specifications of the tower crane climbing structure, suspended around the tower body, are also increasing accordingly. Currently, tower crane climbing structures generally adopt either a welded frame type or a linkage splicing type. While the welded frame type allows for rapid installation, it occupies too much space and may exceed transport size regulations during transportation. The linkage splicing type, although convenient for transportation, has lower installation efficiency. Therefore, existing tower crane climbing structures struggle to balance minimizing space requirements during transportation with high on-site installation efficiency; they cannot achieve both minimal transport space and high installation efficiency during on-site construction. Furthermore, the transition section is connected to the standard tower section via a pin; if the connecting pin fails, there is a risk of separation between the climbing structure and the transition section, posing a significant danger. Utility Model Content

[0003] In view of this, the present invention provides a tower crane climbing structure and a tower crane to solve the problem that the tower crane climbing structure is difficult to balance occupying a small transportation space while having high construction and installation efficiency, as well as the connection safety between the tower crane climbing structure and the transition section.

[0004] In a first aspect, this utility model provides a tower crane climbing structure, comprising: multiple support units, each support unit including at least one vertical beam and multiple sets of horizontal beams connected to the vertical beam, the multiple sets of horizontal beams being spaced apart along the axial direction of the vertical beam, and corresponding horizontal beams on two adjacent support units being detachably connected; and an anti-detachment structure detachably connected to the upper end of the vertical beam, the anti-detachment structure including an anti-detachment member rotatable relative to the vertical beam, the axis of rotation of the anti-detachment member being perpendicular to the axis of the vertical beam, the anti-detachment member having a free state of rotation relative to the vertical beam and a locked state of locking relative to the vertical beam, the anti-detachment member being adapted to cooperate with a transition section to lock the vertical beam and the transition section in the locked state.

[0005] Beneficial effects: By setting up multiple detachably connected support units, the modular assembly of the tower crane climbing structure can be achieved. The small size of each support unit reduces the space occupied during transportation and meets the transportation requirements of not exceeding width limits. Each support unit consists of a vertical beam and multiple sets of horizontal beams connected to the vertical beam as a basic module. During the assembly of multiple support units, only the corresponding horizontal beams on adjacent support units need to be connected. The number of connecting rods required on the construction site is reduced, which can effectively improve the assembly efficiency. At the same time, by setting an anti-detachment structure at the upper end of the vertical beam, and the anti-detachment component in the anti-detachment structure has a free state of rotation relative to the vertical beam and a locked state of locking relative to the vertical beam, the vertical beam and the transition section are locked in the locked state, which realizes the relative fixation of the transition section and the support unit, prevents the climbing structure from moving downward, and improves the safety of installation and jacking operations. Thus, it achieves both small transportation space and high construction and installation efficiency, and ensures the safety of the connection between the tower crane climbing structure and the transition section, ensuring the safe operation of the tower crane.

[0006] In one optional embodiment, the number of support units is four, each support unit including a vertical beam and a horizontal beam connected to both sides of the vertical beam, wherein the horizontal beam connected to the first side of the vertical beam is perpendicular to the horizontal beam connected to the second side of the vertical beam, and the horizontal beams on the four support units are of equal length.

[0007] Beneficial effects: By setting the number of support units to four, with each support unit having a vertical beam connected to mutually perpendicular horizontal beams and the horizontal beams on each support unit being of equal length, each support unit occupies one-quarter of the entire tower crane climbing structure frame. The length of the horizontal beam connected to each support unit is half the vertical distance between two adjacent vertical beams on the frame. This helps to reduce the size of each support unit, facilitating production and transportation. Furthermore, the four support units have similar structures and can be stacked together during transportation, effectively reducing the space occupied during transportation and avoiding the problem of excessive width during transportation.

[0008] In one optional embodiment, the four support units include a first support unit, a second support unit, a third support unit, and a fourth support unit connected end to end in sequence. Each support unit contains multiple sets of crossbeams, including an upper crossbeam assembly, a middle crossbeam assembly, and a lower crossbeam assembly. The first support unit and the second support unit are symmetrically arranged, and the upper crossbeam assembly, the middle crossbeam assembly, and the lower crossbeam assembly of the first support unit and the second support unit each include two crossbeams that are respectively connected to both sides of the vertical beam and are perpendicular to each other. The third support unit and the fourth support unit are symmetrically arranged, and the middle crossbeam assembly and the lower crossbeam assembly of the third support unit and the fourth support unit each include two crossbeams that are respectively connected to both sides of the vertical beam and are perpendicular to each other. The upper crossbeam assembly includes one crossbeam.

[0009] Beneficial effects: By setting each support unit to include an upper crossbeam assembly, a middle crossbeam assembly, and a lower crossbeam assembly, the structural strength of the support unit is enhanced, thereby ensuring the structural strength of the tower crane's climbing structure. Furthermore, by setting the upper, middle, and lower crossbeam assemblies of the first and second support units to each include two crossbeams, complete correspondence during the splicing process of the first and second support units is ensured. By setting the middle and lower crossbeam assemblies of the third and fourth support units to each include two crossbeams, while the upper crossbeam assembly includes only one crossbeam, on the one hand, the correspondence between the middle and lower crossbeam assemblies of the third and fourth support units and the first and second support units is ensured, guaranteeing structural stability. On the other hand, one crossbeam on the third or fourth support unit is used to connect with the upper crossbeam on the adjacent first or second support unit, and an opening is formed between the third and fourth support units for the standard sections of the tower crane to enter, ensuring the smooth progress of the tower crane's tower body installation process.

[0010] In one alternative implementation, one of the two corresponding crossbeams on two adjacent support units has a first connecting portion and the other has a second connecting portion. The tower crane climbing structure further includes a first connecting member, which can selectively connect the first connecting portion and the second connecting portion.

[0011] Beneficial effects: By setting a first connecting part on one of the two interconnected crossbeams and a second connecting part on the other, and connecting the first connecting part and the second connecting part with a first connecting piece, the two crossbeams are connected, thereby connecting the two adjacent support units, and thus assembling the frame of the entire tower crane climbing structure. The structure is simple, easy to operate, easy to assemble and disassemble, and has high work efficiency.

[0012] In one optional embodiment, the upper end of the vertical beam is provided with a first connecting lug plate, the anti-detachment component is an anti-detachment block, the anti-detachment block has a first through hole, the anti-detachment block is hinged to the first connecting lug plate through the first through hole, the anti-detachment block includes a first side portion located on one side of the center line of the first through hole in the horizontal direction, and a second side portion located on the other side of the center line of the first through hole in the horizontal direction, the first side portion has a chamfered corner so that the center of gravity of the anti-detachment block is located on the second side portion; a portion of the first side portion extends out of the vertical beam in the horizontal direction, the anti-detachment block has a horizontal state where it is stationary relative to the vertical beam under its own weight, and a rotational state where the first side portion rotates downward about the center line of the first through hole under the action of an external force; wherein, when the anti-detachment block is in the horizontal state, the lower surface of the anti-detachment block abuts against the upper end face of the vertical beam.

[0013] Beneficial effects: By constructing a notch on the first side of the anti-detachment block, the center of gravity of the anti-detachment block is always located on the second side. At the same time, by setting a portion of the first side of the anti-detachment block to extend a vertical beam horizontally, the remaining portion of the first side and the second side are located directly above the vertical beam. This ensures that the anti-detachment block remains horizontal under its own weight. When the portion of the first side extending to the vertical beam is subjected to an external force from top to bottom, it can rotate downward around the center line of the first through hole. Thus, when the tower crane climbing structure is connected to the transition section, the anti-detachment block can actively avoid obstacles by means of its own weight. Under its own weight, the anti-detachment block remains horizontal, ensuring that both ends of the anti-detachment block act on the two adjacent connecting parts during the descent, preventing the connecting parts from separating.

[0014] In an optional embodiment, the tower crane climbing structure further includes: a first adjusting member connected to the upper crossbeam assembly, a first end of the first adjusting member being located outside the frame formed by the four support units, a second end of the first adjusting member passing through the upper crossbeam assembly and located inside the frame, the first adjusting member selectively adjusting its length extending into the inside of the frame, and the second end of the first adjusting member being adapted to abut against a transition section located inside the frame to adjust the relative position of the transition section and the standard section.

[0015] Beneficial effects: By setting a first adjusting member on the upper crossbeam assembly, and the first adjusting member can selectively adjust its length extending into the frame, when the transition section falls back onto the standard section of the tower body, the first adjusting member can be adjusted on the end face of the main member of the standard section to adjust the misalignment between the transition section and the standard section, correct the misalignment, and ensure that the transition section and the standard section are aligned, thereby ensuring that the transition section and the standard section can be smoothly connected and installed through the pin.

[0016] In one optional embodiment, the tower crane climbing structure further includes a guide structure disposed on the support unit near the vertical beam, the guide structure protruding from the support unit toward the interior of the frame, and the guide structure being adapted to abut against the standard section to provide guidance for the relative movement of the frame and the standard section.

[0017] Beneficial effects: By setting a guide structure on the support unit near the vertical beam, the guide structure abuts against the main limb of the standard section of the tower body. The guide structure guides the tower crane climbing structure as it moves up and down relative to the tower body, improving the stress on the entire frame and enhancing the stability during the relative movement of the two.

[0018] In one optional embodiment, the guide structure includes a guide wheel assembly, which includes a first support frame, a second support frame, a guide wheel, and a second adjusting member. The first support frame is fixedly connected to the crossbeam, the second support frame is rotatably connected to the crossbeam, and the guide wheel is rotatably connected to the second support frame. The first support frame has a third through hole, and the second adjusting member passes through the third through hole and abuts against the second support frame. The second adjusting member can selectively adjust its length extending out of the first support frame to adjust the distance of the guide wheel relative to the crossbeam.

[0019] And / or, the guide structure includes: a slider fixedly connected to the crossbeam at a position near the vertical beam, the slider being adapted to slidably abut against the standard section.

[0020] Beneficial effects: By setting the second adjusting member to pass through the third through hole on the first support frame and abut against the second support frame, the rotation of the second support frame relative to the crossbeam can be adjusted by adjusting the length of the second adjusting member extending out of the first support frame. This causes the guide wheel to change its relative distance to the crossbeam connected to the guide wheel assembly. The guide wheel assembly is an adjustable structure that can be flexibly adjusted. This allows the distance between the guide wheel and the standard section to be adjusted according to actual needs, avoiding the risk of overturning due to excessive bending moment of the transition section and the upper structure during the lifting process caused by an excessive distance between the guide wheel and the standard section, thus improving safety.

[0021] The slider is a fixed guide structure that can withstand a large force. By guiding the standard section with the slider, the stability of the tower crane climbing structure and the standard section during relative movement can be ensured.

[0022] In one optional embodiment, the first support unit and the second support unit each further include: a connecting beam located between the upper crossbeam assembly and the intermediate crossbeam assembly; a lifting cylinder, one end of which is connected to the connecting beam and the other end of which is retractable relative to the connecting beam in a vertical direction; and a lifting crossbeam connected to the end of the lifting cylinder away from the connecting beam.

[0023] Beneficial effects: By setting connecting beams on the first and second support units, installation positions are provided for the lifting cylinders. Through the extension and retraction of the lifting cylinders and the interaction between the lifting beams and the tower body, the tower crane climbing structure can climb relative to the tower body, which is convenient to operate and has high reliability.

[0024] Secondly, this utility model also provides a tower crane, including: a tower crane body and the aforementioned tower crane climbing structure, wherein the tower crane climbing structure is connected to the tower crane body. Since the tower crane includes a tower crane climbing structure and has the same effect as the tower crane climbing structure, it will not be described in detail here. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] The following is combined with Figures 1 to 12 The following describes embodiments of the present invention.

[0042] According to an embodiment of the present invention, a tower crane climbing structure is provided, comprising: multiple support units 1 and an anti-detachment structure 2. Each support unit 1 includes at least one vertical beam 101 and multiple sets of horizontal beams connected to the vertical beam 101. The multiple sets of horizontal beams are spaced apart along the axial direction of the vertical beam 101, and corresponding horizontal beams on adjacent support units 1 are detachably connected. The anti-detachment structure 2 is detachably connected to the upper end of the vertical beam 101. The anti-detachment structure 2 includes an anti-detachment member 201 that can rotate relative to the vertical beam 101. The axis of rotation of the anti-detachment member 201 is perpendicular to the axis of the vertical beam 101. The anti-detachment member 201 has a free state of rotation relative to the vertical beam 101 and a locked state of locking relative to the vertical beam 101. The anti-detachment member 201 is adapted to cooperate with a transition section 10 to lock the vertical beam 101 and the transition section 10 in the locked state. The vertical beam 101 extends in a vertical direction, and the axial direction of the vertical beam 101 refers to the direction in which the axis of the vertical beam 101 is located. Figure 1 The middle arrow points to the "vertical direction"; the top refers to... Figure 1 The end in the direction indicated by the middle arrow, which points to "up".

[0043] The tower crane climbing structure of this embodiment utilizes multiple detachably connected support units 1 to achieve modular assembly. Each support unit 1 is small in size, reducing the space occupied during transportation and meeting the requirement of not exceeding width limits. Each support unit 1 consists of a vertical beam 101 and multiple sets of horizontal beams connected to it, forming a basic module. During assembly, only the corresponding horizontal beams on adjacent support units 1 need to be connected. This reduces the number of connecting members required on-site, effectively improving assembly efficiency. Furthermore, through… An anti-detachment structure 2 is provided at the upper end of the vertical beam 101. The anti-detachment component 201 in the anti-detachment structure 2 has a free state of rotation relative to the vertical beam 101 and a locked state of locking relative to the vertical beam 101. When in the locked state, it locks the vertical beam 101 and the transition section 10, thereby fixing the transition section 10 and the support unit 1 to prevent the climbing structure from moving down and improving the safety of installation and jacking operations. This achieves a balance between occupying less transportation space and having higher construction and installation efficiency, while ensuring the safety of the connection between the tower crane climbing structure and the transition section, thus ensuring the safe operation of the tower crane.

[0044] It should be noted that when the transition section 10 is connected to the tower crane climbing structure, the transition section 10 is connected to the upper end of the tower crane climbing structure, and a support rod 11 extending horizontally is provided at the lower end of the transition section 10. The rotation axis of the anti-detachment component 201 is parallel to the axis of the support rod 11. The anti-detachment component 201 can rotate from below the support rod 11 to above the support rod 11, but cannot rotate from above the support rod 11 to below the support rod 11. Therefore, during the connection process between the tower crane climbing structure and the transition section 10, the tower crane climbing structure relative to the transition section 10... Moving upwards, the anti-detachment component 201 can freely avoid the support rod 11 by rotating around its axis until it moves above the support rod 11. For the downward movement of the tower crane climbing structure relative to the transition section 10, the anti-detachment component 201 and the support rod 11 cooperate to achieve self-locking, preventing the tower crane climbing structure from shifting downwards relative to the transition section 10. Only after removing the support rod 11 or the anti-detachment component 201 can the tower crane climbing structure continue to move downwards. Therefore, the cooperation between the anti-detachment structure 2 and the transition section 10 improves the safety of installation and jacking operations. Here, "horizontal direction" refers to the direction relative to... Figure 9 The direction indicated by the middle arrow is perpendicular to the "vertical direction"; below refers to... Figure 9 The middle arrow points in the direction of "down"; "up" refers to... Figure 9 The direction indicated by the middle arrow is "up".

[0045] In one embodiment, there are four support units 1. Each support unit 1 includes a vertical beam 101 and crossbeams connected to both sides of the vertical beam 101. The crossbeams connected to the first side of the vertical beam 101 are perpendicular to the crossbeams connected to the second side of the vertical beam 101, and the lengths of the crossbeams on the four support units 1 are equal. It should be noted that the vertical beam 101 is a square column, and the first and second sides of the vertical beam 101 are two adjacent sides of the square column. Multiple sets of crossbeams are connected to the vertical beam 101 at intervals along its axial direction. Each set of crossbeams includes two crossbeams connected to two adjacent sides of the vertical beam 101. By setting the number of support units 1 to four, with each support unit 1 having a vertical beam 101 connected to mutually perpendicular horizontal beams and the horizontal beams on each support unit 1 having equal lengths, each support unit 1 occupies one-quarter of the frame 100 of the entire tower crane climbing structure. The length of the horizontal beam connected to each support unit 1 is half the vertical distance between two adjacent vertical beams 101 on the frame 100. This helps to reduce the size of each support unit 1, facilitating production and transportation. Furthermore, the four support units 1 have similar structures and can be stacked together during transportation, effectively reducing the space occupied during transportation and avoiding the problem of excessive width during transportation.

[0046] In one embodiment, further combination Figure 1 As shown, the four support units 1 include a first support unit 110, a second support unit 120, a third support unit 130, and a fourth support unit 140 connected end to end in sequence. Each support unit 1 contains multiple sets of crossbeams, including an upper crossbeam assembly, a middle crossbeam assembly, and a lower crossbeam assembly. The first support unit 110 and the second support unit 120 are symmetrically arranged, and the upper crossbeam assembly, the middle crossbeam assembly, and the lower crossbeam assembly of the first support unit 110 and the second support unit 120 each include two crossbeams that are respectively connected to both sides of the vertical beam 101 and are perpendicular to each other. The third support unit 130 and the fourth support unit 140 are symmetrically arranged, and the middle crossbeam assembly and the lower crossbeam assembly of the third support unit 130 and the fourth support unit 140 each include two crossbeams that are respectively connected to both sides of the vertical beam 101 and are perpendicular to each other. The upper crossbeam assembly includes one crossbeam.

[0047] The first support unit 110, the second support unit 120, the third support unit 130, and the fourth support unit 140 are connected end to end to form a frame 100 of the tower crane climbing structure with a square cross-section. By including an upper crossbeam assembly, a middle crossbeam assembly, and a lower crossbeam assembly in each support unit 1, the structural strength of the support unit 1 is enhanced, thereby ensuring the structural strength of the tower crane climbing structure. Furthermore, by ensuring that the upper, middle, and lower crossbeam assemblies of the first support unit 110 and the second support unit 120 each include two crossbeams, complete correspondence is ensured during the splicing of the first support unit 110 and the second support unit 120. The third support unit 130 and the fourth support unit 140 are also connected end to end to form a frame 100 of the tower crane climbing structure with a square cross-section. The middle crossbeam assembly and the lower crossbeam assembly of the support unit 140 each include two crossbeams, while the upper crossbeam assembly includes only one crossbeam. On the one hand, this ensures the correspondence between the middle crossbeam assembly and the lower crossbeam assembly of the third support unit 130 and the fourth support unit 140 and the first support unit 110 and the second support unit 120, thus ensuring the stability of the structure. On the other hand, one crossbeam on the third support unit 130 or the fourth support unit 140 is used to connect with the upper crossbeam 102 on the adjacent first support unit 110 or the second support unit 120. Furthermore, an opening is formed between the third support unit 130 and the fourth support unit 140 for the standard section 20 of the tower crane to enter, ensuring the smooth progress of the tower crane's tower body installation process.

[0048] The first support unit 110 and the second support unit 120 are symmetrically arranged, which facilitates the assembly of the two. The side directly connected to the two has good integrity and reasonable stress distribution after assembly.

[0049] Specifically, the upper crossbeam assembly of the first support unit 110 and the second support unit 120 includes two upper crossbeams 102, with one upper crossbeam 102 connected to each adjacent side of the vertical beam 101, and the two upper crossbeams 102 are perpendicular to each other; the middle crossbeam assembly includes two middle crossbeams 103, which are correspondingly arranged with the two upper crossbeams 102, and are connected to the upper crossbeams 102 on the same side of the vertical beam 101, and the two middle crossbeams 103 are perpendicular to each other; the lower crossbeam assembly includes two lower crossbeams 104, which are correspondingly arranged with the two middle crossbeams 103, and are connected to the middle crossbeams 103 on the same side of the vertical beam 101, and the two lower crossbeams 104 are perpendicular to each other. The arrangement of the third support unit 130 and the fourth support unit 140 is similar and will not be described in detail here.

[0050] It should be noted that, taking the connection between the first support unit 110 and the second support unit 120 as an example, the upper crossbeam 102 of the first support unit 110 is connected to the upper crossbeam 102 of the second support unit 120, the middle crossbeam 103 of the first support unit 110 is connected to the middle crossbeam 103 of the second support unit 120, and the lower crossbeam 104 of the first support unit 110 is connected to the lower crossbeam 104 of the second support unit 120; the connections between other support units are similar and will not be described in detail here.

[0051] In one embodiment, one of the corresponding crossbeams on two adjacent support units 1 has a first connecting portion 106 and the other has a second connecting portion 107. The tower crane climbing structure also includes a first connecting member 3, which can selectively connect the first connecting portion 106 and the second connecting portion 107. The two corresponding crossbeams on two adjacent support units 1 refer to an upper crossbeam 102, an intermediate crossbeam 103, or a lower crossbeam 104 on each of the two adjacent support units 1 used for connection. By providing a first connecting portion 106 on one of the two interconnected crossbeams and a second connecting portion 107 on the other, and connecting the first connecting portion 106 and the second connecting portion 107 together using the first connecting member 3, the two crossbeams are connected, thereby connecting the two adjacent support units 1, and thus assembling the entire tower crane climbing structure frame 100. The structure is simple, easy to operate, convenient to assemble and disassemble, and has high work efficiency.

[0052] In one embodiment, the first connecting part 106 and the second connecting part 107 are both hinge seats, and the hinge seats are provided with through holes. The first connecting member 3 can be selectively inserted into the through holes of the two hinge seats to realize the connection between the two hinge seats.

[0053] In one embodiment, the first connector 3 is a pin, which has a simple structure, stable connection, high strength, high reliability, and is easy to disassemble and operate.

[0054] Preferably, the first connecting part 106 or the second connecting part 107 is located at the end of the crossbeam away from the vertical beam 101. The first connecting part 106 and the second connecting part 107 each include two hinge plates arranged in parallel. The two hinge plates on one of the first connecting part 106 and the second connecting part 107 are located between the two hinge plates of the other two. A through hole is provided on the hinge plate, and the center line of the through hole is perpendicular to the axis of the crossbeam.

[0055] In other embodiments, the number of support units 1 can be two or three. When there are two support units 1, each support unit 1 includes two vertical beams 101 and corresponding horizontal beams. The overall cross-section of the support unit 1 is U-shaped, and the open ends of the two support units 1 face each other, so as to splice them into a frame 100 with a quadrilateral cross-section. When there are three support units 1, two of the support units 1 have a vertical beam 101 and multiple sets of horizontal beams connected to the adjacent sides of the vertical beam 101, and the other support unit 1 has two vertical beams 101 and corresponding horizontal beams, so as to splice them into a frame 100 with a quadrilateral cross-section.

[0056] In one embodiment, the upper end of the vertical beam 101 is provided with a first connecting ear plate 111, and the anti-detachment member 201 is an anti-detachment block. The anti-detachment block is provided with a first through hole 211. The anti-detachment block is hinged to the first connecting ear plate 111 through the first through hole 211. The anti-detachment block includes a first side portion located on one side of the center line of the first through hole 211 along the horizontal direction, and a second side portion located on the other side of the center line of the first through hole 211 along the horizontal direction. The first side portion is provided with a chamfer so that the center of gravity of the anti-detachment block is located on the second side portion. A portion of the first side portion extends out of the vertical beam 101 along the horizontal direction. The anti-detachment block has a horizontal state where it is stationary relative to the vertical beam 101 under its own weight, and a rotational state where the first side portion rotates downward around the center line of the first through hole 211 under the action of an external force. When the anti-detachment block is in the horizontal state, the lower surface of the anti-detachment block abuts against the upper end surface of the vertical beam 101.

[0057] It should be noted that "upper end" refers to... Figure 1 The end indicated by the middle arrow in the direction of "up"; the anti-detachment block is hinged to the first connecting ear plate 111 through the first through hole 211, so the axis of rotation of the anti-detachment block is the center line of the first through hole 211; the anti-detachment block is placed on the upper end face of the vertical beam 101, and a portion of the first side of the anti-detachment block away from the second side extends horizontally out of the vertical beam 101, that is, extends to the outside of the frame 100. The other part of the first side and the second side are located directly above the vertical beam 101. When the portion of the first side extending to the outside of the frame 100 is subjected to a force from top to bottom, The anti-detachment block can rotate around the center line of the first through hole 211, that is, the first side rotates downward around the center line of the first through hole 211 and the second side rotates upward around the center line of the first through hole 211, thus achieving active obstacle avoidance. When the external force disappears, the anti-detachment block can return to a horizontal state under its own gravity. When the part of the first side extending outside the frame 100 is subjected to an upward force, the anti-detachment block cannot rotate because the vertical beam 101 provides an upward force to the second side of the anti-detachment block, and the anti-detachment block remains in a horizontal state. The horizontal state of the anti-detachment block is the locked state of the anti-detachment component 201, and the rotating state of the anti-detachment block is the free state of the anti-detachment component 201.

[0058] By constructing a notch on the first side of the anti-detachment block, the center of gravity of the anti-detachment block is always located on the second side. At the same time, by setting a portion of the first side of the anti-detachment block to extend horizontally outward along the vertical beam 101, the remaining portion of the first side and the second side are located directly above the vertical beam 101, thus ensuring that the anti-detachment block remains horizontal under its own weight. When the portion of the first side extending outward along the vertical beam 101 is subjected to an external force from top to bottom, it can rotate downward around the centerline of the first through hole 211. Thus, when the tower crane climbing structure is connected to the transition section 10, the anti-detachment block can actively avoid obstacles by means of its own weight. Under its own weight, the anti-detachment block remains horizontal, thus ensuring that the two ends of the anti-detachment block act on the two adjacent connecting parts respectively during the descent, preventing the separation of the connecting parts.

[0059] In one embodiment, the first connecting ear plate 111 has a second through hole 121, and the anti-detachment structure 2 further includes a second connector 202, which detachably passes through the second through hole 121 and the first through hole 211. By setting the second connector 202 of the anti-detachment structure 2 to detachably pass through the second through hole 121 on the first connecting ear plate 111 and the first through hole 211 on the anti-detachment block, a detachable connection between the anti-detachment block and the vertical beam 101 is achieved, facilitating maintenance and replacement.

[0060] It should be noted that the first connecting lug 111 is also provided with a first connecting hole 122 spaced apart from the second through hole 121. The first connecting hole 122 is used to connect with the transition section 10. The transition section 10 is provided with a second connecting lug 12 corresponding to the first connecting lug 111. The second connecting lug 12 is provided with a second connecting hole corresponding to the first connecting hole 122. The first connecting hole 122 and the second connecting hole are connected by a connecting shaft 13, thereby realizing the fixed connection between the tower crane climbing structure and the transition section 10. The self-locking between the anti-detachment structure 2 and the transition section 10 can prevent the tower crane climbing structure from moving down relative to the transition section 10 when the connection between the transition section 10 and the standard section 20 of the tower body fails, thereby improving safety.

[0061] Further integration Figure 5 and Figure 11As shown, after the corner is notched on the first side of the anti-detachment block, an inclined surface 212 is formed on the first side. The inclined surface 212 connects the upper side of the anti-detachment block and the side of the anti-detachment block away from the vertical beam 101 in the horizontal direction. When the tower crane climbing structure moves upward relative to the transition section 10, the inclined surface 212 first contacts the support rod 11 on the transition section 10. The inclined surface 212 provides guidance to facilitate the anti-detachment block to rotate around its axis. The anti-detachment block has an eccentric structure, so that the anti-detachment block is in a horizontal state under its own weight. The lower end face of the anti-detachment block abuts against the upper end face of the vertical beam 101. The anti-detachment block will not rotate when subjected to the upward force of the support rod 11, thereby realizing the self-locking between the anti-detachment block and the support rod 11.

[0062] In one embodiment, the upper side of the second side of the anti-detachment block may also be constructed with a notch, but the notch on the second side is smaller than the notch on the first side, so as to ensure that the center of gravity of the anti-detachment block is always located on the second side.

[0063] In one embodiment, the upper side of the anti-detachment block is also connected to a lifting lug 213 to facilitate lifting and transporting the anti-detachment block.

[0064] In one embodiment, the second connector 202 is a pin, which has a simple structure, is easy to assemble and disassemble, and has high reliability. The support rod 11 is also a pin, which has a simple structure, is easy to assemble and disassemble, has high strength, and high reliability.

[0065] In one embodiment, the tower crane climbing structure further includes: a first adjusting member 4 connected to the upper crossbeam assembly, the first end of the first adjusting member 4 being located outside the frame 100 formed by the four support units 1, and the second end of the first adjusting member 4 passing through the upper crossbeam assembly and located inside the frame 100, the first adjusting member 4 selectively adjusting its length extending inside the frame 100, and the second end of the first adjusting member 4 being adapted to abut against a transition section 10 located inside the frame 100 to adjust the relative position of the transition section 10 and the standard section 20. Here, the outer side of the frame 100 refers to the side of the frame 100 away from its center; the inner side of the frame 100 refers to the side of the frame 100 facing its center. By setting a first adjusting member 4 on the upper crossbeam assembly, and selectively adjusting the length of the first adjusting member 4 extending into the inner side of the frame 100, when the transition section 10 falls back onto the standard section 20 of the tower body, by adjusting the first adjusting member 4 acting on the main end face of the standard section 20, the misalignment between the transition section 10 and the standard section 20 can be adjusted, the misalignment can be corrected, and the transition section 10 and the standard section 20 can be aligned, thereby ensuring that the transition section 10 and the standard section 20 can be smoothly connected and installed through the pin.

[0066] In one embodiment, a connecting plate 112 is fixedly connected to the lower side of the upper crossbeam 102. The connecting plate 112 has a through hole. The first adjusting member 4 includes a bolt and a nut. The bolt passes through the through hole on the connecting plate 112. There can be two nuts. A nut is provided on the inner side and the outer side of the connecting plate 112 facing the frame 100. The nuts cooperate with the bolt to fix the bolt to the connecting plate 112. The distance of the bolt extending into the inner side of the frame 100 can be adjusted by turning the nuts.

[0067] In one embodiment, the tower crane climbing structure further includes a guide structure. The guide structure is positioned on the support unit 1 near the vertical beam 101, protruding from the support unit 1 towards the interior of the frame 100. The guide structure is adapted to abut against the standard section 20 to provide guidance for the relative movement of the frame 100 and the standard section 20. By providing the guide structure on the support unit 1 near the vertical beam 101, and abutting against the main limb of the standard section 20 of the tower body, the guide structure guides the tower crane climbing structure as it moves up and down relative to the tower body, improving the overall frame stress distribution and enhancing the stability during relative movement.

[0068] Specifically, the guide structure is located on the crossbeam near the vertical beam 101, so that the guide structure can abut against the vertical beam on the standard section 20.

[0069] In one embodiment, the guide structure includes a guide wheel assembly 5, which includes a first support frame 501, a second support frame 502, a guide wheel 503, and a second adjusting member 504. The first support frame 501 is fixedly connected to the crossbeam, the second support frame 502 is rotatably connected to the crossbeam, and the guide wheel 503 is rotatably connected to the second support frame 502. The first support frame 501 has a third through hole 511, and the second adjusting member 504 passes through the third through hole 511 and abuts against the second support frame 502. The second adjusting member 504 can selectively adjust its length extending out of the first support frame 501 to adjust the distance of the guide wheel 503 relative to the crossbeam. By setting the second adjusting member 504 to pass through the third through hole 511 on the first support frame 501 and abut against the second support frame 502, the second support frame 502 can be adjusted to rotate relative to the crossbeam by adjusting the length of the second adjusting member 504 extending out of the first support frame 501. This causes the guide wheel 503 to change its relative distance to the crossbeam connected to the guide wheel assembly 5. The guide wheel assembly 5 is an adjustable structure that can be flexibly adjusted. This allows the distance between the guide wheel 503 and the standard section 20 to be adjusted according to actual needs, avoiding the risk of overturning due to excessive bending moment of the transition section 10 and the upper structure during the lifting process caused by excessive distance between the guide wheel 503 and the standard section 20, thus improving safety.

[0070] In one embodiment, the first support frame 501 has a first support plate, and the second support frame 502 has a second support plate. The first support plate and the second support plate are arranged opposite to each other. The first support plate is fixed relative to the crossbeam connecting the guide wheel assembly 5. The second support plate is rotatably connected to the third connecting part 505 on the crossbeam through a rotating part. The rotating part and the third connecting part 505 are connected by a pin. The second adjusting member 504 is a bolt. The bolt is connected to the first support frame 501 through a nut. After passing through the first support plate of the first support frame 501, the bolt abuts against the second support plate and acts on the second connecting plate. The second support frame 502 drives the guide wheel 503 to rotate around the third connecting part 505, thereby realizing the displacement of the guide wheel 503 relative to the crossbeam.

[0071] In one embodiment, the guide structure includes a slider 6, which is fixedly connected to the crossbeam near the vertical beam 101. The slider 6 is adapted to slidably abut against the standard section 20. The slider 6 is a fixed guide structure that can bear a large force. By guiding the standard section 20 through the slider 6, the stability of the tower crane climbing structure and the standard section 20 during relative movement can be ensured.

[0072] In one embodiment, guide structures are provided on the intermediate crossbeam group and the lower crossbeam group. Each support unit 1 has a set of guide structure components at a position near the vertical beam 101 on the intermediate crossbeam group and the lower crossbeam group. Each guide structure component includes two guide structures. One guide structure is provided on each of the crossbeams located on both sides of the vertical beam 101. Each set of guide structure components acts on different sides of the same vertical beam of the standard section 20, thereby increasing the uniformity of the guide support provided to the standard section 20.

[0073] Preferably, a guide structure assembly includes a guide wheel assembly 5 and a slider 6, employing a combination of adjustable and fixed guide structures. This shared structure can control the unbalanced bending moment of the upper part of the tower crane's climbing structure, ensuring the maximum tilt angle of the upper structure during jacking remains within a safe range. It also reduces the risk of overturning caused by excessive bending moment in the transition section 10 and upper structure during jacking due to excessive manual adjustment of the guide wheel's distance from the standard section 20. Furthermore, it can prevent the problem of insufficient clearance between the outer contour of the actual guide wheel and the end face of the standard section, which could lead to wear on the end face of the main limb of the standard section and abnormal noise. Additionally, it can increase load-bearing capacity and reliability.

[0074] It is understood that, as an alternative implementation, a guide structure assembly may also include only two guide wheel assemblies 5, thereby improving the adjustability of the guide structure in all directions for the distance between the standard section 20 and the frame 100 of the tower crane climbing structure.

[0075] Specifically, the guide structures connected to the lower crossbeams 104 of the four support units 1 are all guide wheel assemblies 5; the guide structures connected to the middle crossbeams 103 of the first support unit 110 and the second support unit 120 are all guide wheel assemblies 5; one of the guide structure assemblies connected to the lower crossbeams 104 of the third support unit 130 and the fourth support unit 140 is a guide wheel assembly 5 and the other is a slider 6. The guide structures provided on the middle crossbeams 103 and the lower crossbeams 104 of the support units 1, and the first adjusting member 4 provided on the upper crossbeam 102, enable each support unit 1 to have three layers of adjusting devices.

[0076] In one embodiment, the first support unit 110 and the second support unit 120 each further include: a connecting beam 105, a lifting cylinder 7, and a lifting crossbeam 701. The connecting beam 105 is located between the upper crossbeam assembly and the middle crossbeam assembly. Specifically, the connecting beam 105 is located between the upper crossbeam 102 and the middle crossbeam 103 on one side of the first support unit 110. One end of the lifting cylinder 7 is connected to the connecting beam 105, and the other end can extend and retract relative to the connecting beam 105 in the vertical direction. The lifting crossbeam 701 is connected to the end of the lifting cylinder 7 away from the connecting beam 105. By providing the connecting beam 105 on the first support unit 110 and the second support unit 120, an installation position is provided for the lifting cylinder 7. Through the extension and retraction of the lifting cylinder 7 and the interaction between the lifting crossbeam 701 and the tower body, the climbing structure of the tower crane can be lifted relative to the tower body, which is convenient to operate and has high reliability. It should be noted that the plane containing the axis of the connecting beam 105 is parallel to the plane containing the axis of the crossbeam, and the width of the connecting beam 105 is wider than that of the crossbeam, resulting in greater structural strength. This ensures reliable connection support for the lifting cylinder 7 and improves safety.

[0077] In one embodiment, the lifting cylinder 7 is a hydraulic cylinder, preferably a dual hydraulic cylinder, which can reduce the size of a single hydraulic cylinder. It is understood that, as an alternative implementation, the lifting cylinder 7 can also be an electric cylinder, which can achieve precise displacement for multi-cylinder lifting.

[0078] In one embodiment, the support unit 1 further includes auxiliary rods, which include a horizontal rod 1081, a vertical rod 1082, and a diagonal rod 1083. The horizontal rod is located between the middle horizontal beam 103 and the lower horizontal beam 104 and extends horizontally; the vertical rod 1082 is parallel to the vertical beam 101 and is connected to the end of the horizontal rod 1081 away from the vertical beam 101 or to the end of the horizontal beam away from the vertical beam 101; the diagonal rod 1083 is inclined and connects the horizontal beam and the horizontal rod 1081 or between horizontal beams located on different layers to increase the structural strength of the support unit 1.

[0079] In one embodiment, the tower crane climbing structure further includes a connecting rod 109, the axis of which is located on the plane of the axis of the upper crossbeam 102, and the connecting rod 109 is connected between the third support unit 130 and the fourth support unit 140 to increase the structural strength of the frame 100 of the tower crane climbing structure.

[0080] In one embodiment, a first maintenance platform 801 is provided on the first support unit 110, and a second maintenance platform 802 is provided on the second support unit 120, which facilitates the assembly and maintenance of the climbing claw and the hydraulic cylinder.

[0081] The tower crane climbing structure in this embodiment adopts a modular design. The four support units 1 have similar overall structures and are all 1 / 4 of the frame 100 of the entire climbing structure. The two adjacent support units 1 are connected by pins, which can better meet the working conditions of frequent disassembly without the connection becoming unstable.

[0082] In this embodiment, the first connecting lug 111 at the upper end of the tower crane climbing structure forms a hinge support, which is directly connected to the transition section 10 via a pin. In addition, the second connecting lug 12 on the transition section 10 is coupled to the first connecting lug 111 of the tower crane climbing structure via an anti-detachment component 201, a second connecting component 202, and a support rod 11. During the connection between the tower crane climbing structure and the transition section 10, the anti-detachment component 201 can freely avoid the support rod 11, and during the descent process, it can self-lock to prevent the tower crane climbing structure from moving downwards. Only after the support rod 11 is removed can the tower crane climbing structure continue to move downwards, improving the safety of installation and jacking operations. The anti-detachment component 201 is an eccentric anti-detachment block, and the upper side of the extended portion of the anti-detachment block beyond the vertical beam 101 is inclined. When the inclined surface is subjected to external force, the anti-detachment block rotates around the second connecting component 202.

[0083] The modular and anti-detachment tower crane climbing structure of this embodiment has a compact overall structure, which can better balance the requirements of small transportation space and high installation efficiency. It can also reduce the risk of failure of the connecting pin between the transition section 10 and the standard section 20, and separation of the climbing structure from the transition section 10. It can also correct the misalignment between the transition section 10 and the standard section end face when the transition section 10 falls back to the tower body, reducing the problem of the connecting pin shaft being unable to be installed due to misalignment. Finally, it can reduce the risk of excessive upper eccentric bending moment due to human pursuit of adjusting the gap between the guide wheel 503 and the tower body end face, which affects the jacking safety. It is of great significance to improve the safety of tower crane jacking operations.

[0084] The usage process of the tower crane climbing structure in this embodiment is as follows:

[0085] First, four support units 1 are assembled into a climbing structure frame 100 via the first connector 3. Then, the guide wheel assembly 5 and the slider 6 are sequentially installed onto the corresponding connection positions on the support unit 1. The second adjusting component 504 is adjusted to act on the second support frame 502 to ensure that the guide wheel 503 has a suitable distance from the end face of the standard section 20. Then, the lifting cylinder 7 is connected to the connecting beam 105 and the lifting crossbeam 701 for subsequent operations. The tower crane climbing structure first hinges the anti-detachment component 201 to the first connecting ear plate 111 via the second connector 202. Then, under the drive of the lifting cylinder 7 and the guidance of the guiding structure, the tower crane climbing structure moves upward as a whole. When it moves to the vicinity of the second connecting ear plate 12 on the transition section 10, the anti-detachment component 201 rotates around the second connector 202 under the action of the support rod 11, thus smoothly moving to the second connecting component 202. On the upper side of the support rod 11, without removing the support rod 11, the transition section 10 cannot be separated from the tower crane climbing structure, achieving self-locking. Then, the second connecting ear plate 12 and the first connecting ear plate 111 are connected and assembled through the connecting shaft 13 to achieve the connection between the transition section 10 and the tower crane climbing structure. When it is necessary to separate the transition section 10 from the tower crane climbing structure, the support rod 11 is removed first, and then the connecting shaft 13 is removed. During the jacking and section addition process, when the transition section 10 descends to near the end face of the tower body, there is a misalignment between the main body of the transition section 10 and the standard section 20, which affects the installation of the connecting pin used to connect the transition section 10 and the standard section 20. The first adjusting member is adjusted to act on the end face of the main body of the transition section 10, and then the misalignment is checked so that the connecting pin can connect and fasten the transition section 10 and the standard section 20.

[0086] According to an embodiment of this utility model, another aspect provides a tower crane, including: a tower crane body and the aforementioned tower crane climbing structure, the tower crane climbing structure being connected to the tower crane body. The tower crane body includes: a tower body, which is formed by stacking a plurality of standard sections 20 sequentially in a vertical direction; and a transition section 10 located at the upper end of the tower body. The tower crane climbing structure is sleeved around the outer perimeter of the tower body, and the transition section 10 is detachably connected to the upper end of the tower crane climbing structure.

[0087] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
