DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments: like Figure 1-Figure 16As shown, this embodiment provides a climbing device for a crane to rise and fall on an H-type bridge tower, comprising a climbing assembly, a triangular connector 7, a platform truss beam 8 and an adsorption assembly. The climbing assembly can be sleeved on the tower column 6 of the H-type bridge tower to install the climbing assembly on the tower column 6. One end of the triangular connector 7 is connected to the platform truss beam 8, and the triangular connector 7 is used to support the platform truss beam 8. The platform truss beam 8 is used to place the crane or other equipment and other related equipment, devices or components. The other end of the triangular connector 7 is rotatably connected to the climbing assembly, so that the triangular connector 7 can rotate relative to the climbing assembly, so that the end surface of the triangular connector 7 away from the climbing assembly is in a horizontal state, so that the platform truss beam 8 supported by the triangular connector 7 can always be in a horizontal state.

[0018] The tower column 6 of the H-type bridge tower may be curved, and the climbing assembly needs to move along the curved tower column 6 to reach the tower column 6 at different heights. Therefore, the climbing assembly needs to make adaptive adjustments following the curved direction of the tower column 6 to adapt to the tower column 6. To this end, the triangular connector 7 needs to rotate so that after the climbing assembly is adjusted, the end surface of the triangular connector 7 away from the climbing assembly is always in a horizontal state, ensuring that the supported platform truss beam 8 is also always in a horizontal state.

[0019] The climbing component can be installed and connected to the tower column 6 through the adsorption component, one end of the adsorption component is connected to the climbing component, and the other end of the adsorption component is a free end, that is, when it needs to be used, the other end of the adsorption component is installed and connected to the tower column 6, so that the climbing component is installed and connected to the tower column 6, and when it is not needed, the other end of the adsorption component can be removed from the tower column 6, and then the climbing component is also removed from the tower column 6.

[0020] Exemplarily, the adsorption assembly includes a male accessory 17 and a female accessory 5, the male accessory 17 and the female accessory 5 are detachably connected, the male accessory 17 is fixedly mounted on the climbing assembly, and the female accessory 5 is used to be mounted on the tower column 6. The female accessory 5 can be fixedly or detachably mounted on the tower column 6, and a plurality of female accessories 5 can be provided, and each female accessory 5 is spaced and distributed along the extension direction of the tower column 6.

[0021] Exemplarily, the male accessory 17 is a seat plate or a groove pre-dug on the tower column 6, that is, a reserved groove, and the female accessory 5 is a wall attachment device. The female accessory 5 is embedded in the tower column 6 as an embedded part. The wall attachment device is a prior art, for example, a wall attachment device or a wall attachment frame or a wall attachment connection component commonly used in tower cranes. When the female accessory 5 is a groove, it needs to be pre-dug on the tower column 6, and the movable end of the wall attachment device can be embedded in the groove to maintain a stable connection with the tower column 6. When it is a seat plate, the seat plate can be fixedly or detachably installed on the tower column 6, and the wall attachment device is connected to the seat plate, so that the male accessory 17 is connected to the female accessory 5, so that the climbing component is connected to the tower column 6 through the adsorption device.

[0022] Exemplarily, the triangular connector 7 is a triangular structure (ie, a triangle), the top angle of the triangular connector 7 is rotatably connected to the climbing assembly, and the bottom side of the triangle is in contact with the platform truss beam 8 .

[0023] Exemplarily, the triangular connector 7 is connected to the climbing assembly via the rotating shaft 3 , and the rotating shaft 3 runs through the triangular connector 7 and the climbing assembly, so that the triangular connector 7 can rotate relative to the rotating shaft 3 .

[0024] Exemplarily, it also includes a limit assembly for limiting the upward flipping of the platform truss beam 8, the limit assembly includes a rail 11, a rolling bearing 25 and a locking member, the rail 11 is fixedly connected to one end of the platform truss beam 8 near the triangular connector 7, the triangular connector 7 is slidably mounted on the rail 11, that is, the triangular connector 7 and the rail 11 can slide relative to each other, the rolling bearing 25 is mounted on the rail 11 and between the rail 11 and the triangular connector 7, and the rolling bearing 25 can reduce the resistance of the triangular connector 7 and the rail 11 during relative sliding. The locking member is used to release or lock the relative sliding between the rail 11 and the triangular connector 7. When the locking member is locked, the rail 11 and the triangular connector 7 are prohibited from sliding relative to each other, that is, the rail 11 and the triangular connector cannot slide relative to each other. When the locking member is released, the rail 11 and the triangular connector 7 are allowed to slide relative to each other, that is, relative sliding can be achieved. The locking member can be a bolt. When relative sliding is required, the bolt is loosened to keep the triangular connector 7 and the rail 11 relatively slidable. When relative sliding is required to be prohibited, the bolt is tightened to tighten the bolt between the rail 11 and the triangular connector 7, thereby fixing the connection between the triangular connector 7 and the rail 11 to avoid relative sliding between the triangular connector 7 and the rail 11, so as to ensure the stability of the entire device when lifting operations are required. The connection and coordination between the rail 11 and the triangular connector 7 can prevent the platform truss beam 8 from flipping upward.

[0025] For example, one end of the platform truss beam 8 is a cantilever end, and the crane installed on the platform truss beam 8 can be moved to the cantilever end so that the crane can perform lifting operations from the side of the platform truss beam 8. And the truss height of the platform truss beam 8 is increased at the position of the cantilever section to increase the truss bending bearing capacity there.

[0026] Exemplarily, the platform truss beam 8 includes two main trusses arranged in parallel and at intervals, and the two main trusses are connected together by a plurality of transverse beams. In order to prevent the transverse beams from affecting the device during climbing, descending or hoisting operations, the transverse beams can be connected to the main trusses by bolts so that the transverse beams at the corresponding positions can be removed as needed.

[0027] Exemplarily, the climbing assembly includes a support frame 4, a guide rail 2 mounted on the support frame 4, and a driving assembly. One end of the adsorption assembly is fixedly connected to the guide rail 2, and a triangular connector 7 is connected to the support. When the adsorption assembly is distributed along the extension direction of the tower column 6, the guide rail 2 is also arranged along the extension direction of the tower column 6. The driving assembly can move up and down along the guide rail 2 and drive the support frame 4 to move up and down along the guide rail 2 together.

[0028] The support frame 4 includes a support body 41 and a support rotating column 42. The support body 41 includes an open space 24 for sleeve-mounting the support member on the tower column 6. The open space 24 has an opening. The support rotating column 42 is installed on the side of the support body 41 close to the opening. The support rotating column 42 is rotatably installed on the support body 41 through the pin 21, so that the support rotating column 42 can be rotated to at least a first position and a second position. One end of the support rotating column 42 is connected to the pin 21, and the pin 21 is rotatably installed on the support body 41. The other end of the support rotating column 42 is a free end.

[0029] First position: the support rotating column 42 is located in the opening and is closed to the opening, thereby turning the open space 24 into a closed space.

[0030] The second position: the support rotating column 42 is located outside the opening so that the opening is open, and the open space 24 remains an open area with an opening, that is, a non-enclosed space.

[0031] refer to Fig. 9 and Fig.11 , Fig. 9 The support rotating column 42 is in the first position, Fig.11 The support rotating column 42 is located at the second position.

[0032] The support rotating column 42 can be rotated to the first position and the second position respectively, so that when the climbing assembly climbs to the position of the beam 1 where the tower column 6 is located, the support rotating column 42 can be rotated to the second position, so that the support frame 4 can pass (cross) the beam 1 on the tower column 6, and the climbing assembly will not be blocked by the beam 1. After crossing the beam 1, the support rotating column 42 can be rotated to the first position again.

[0033] Exemplarily, the support frame 4 is also equipped with a plurality of pads 22, each of which is stacked together, and the pads 22 are located at one end of the opening close to the free end of the support rotating column 42. By stacking one or more pads 22, the height of the entire pad 22 can be adjusted to adapt to the length of the opening, thereby adapting to the slight deformation of the support frame 4, and at the same time, the length of the rotating column 42 can be designed to be slightly shorter than the length of the opening, so that the rotating column 42 will not be blocked when it is rotated in. .

[0034] Exemplarily, the driving assembly includes a hydraulic cylinder 9 , an upper supporting leg 13 and a lower supporting leg 14 , wherein the output end of the hydraulic cylinder 9 is connected to the lower supporting leg 14 , and the other end of the hydraulic cylinder 9 opposite to the output end is connected to the upper supporting leg 13 .

[0035] The upper support leg 13 includes an upper support frame (not shown in the figure), an upper bearing block 15 and an upper stopper 16 mounted on the upper support frame, the upper support frame is slidably mounted on the guide rail 2, the upper stopper 16 is arranged along the axial direction of the guide rail 2, that is, vertically arranged, and the upper stopper 16 is arranged parallel to the guide rail 2 and spaced apart. One end of the upper bearing block 15 is connected to the upper stopper 16, the upper bearing block 15 is rotatable, and the other end of the upper bearing block 15 is movably abutted against the guide rail 2.

[0036] The lower support leg 14 includes a lower support frame (not shown in the figure) and a lower bearing block 19 and a lower stopper 20 mounted on the lower support frame. The lower support frame is slidably mounted on the guide rail 2. The lower stopper 20 is arranged along the axial direction of the guide rail 2, that is, vertically arranged. The lower stopper 20 is arranged parallel to the guide rail 2 and spaced apart. One end of the lower bearing block 19 is connected to the lower stopper 20, and the lower bearing block 19 is rotatable. The other end of the lower bearing block 19 is movably abutted against the guide rail 2.

[0037] The guide rail 2 includes a guide rail 2 support bar (not shown in the figure) and a plurality of support blocks 18 arranged on the guide rail 2 support bar, each support block 18 is arranged at equal intervals along the axial direction (i.e., the extension direction) of the support bar, and a notch is formed between two adjacent support blocks 18. The other end of the upper bearing block 15 and the other end of the lower bearing block 19 both extend into the notch.

[0038] During the rotation process, the upper bearing block 15 and the lower bearing block 19 can rotate from abutting against the current notch to the next adjacent notch, thereby achieving climbing or descending.

[0039] Taking climbing upward (i.e. ascending) as an example, when climbing is required, the hydraulic cylinder 9 is started, and when the output end of the hydraulic cylinder 9 extends outward, the lower support leg 14 is driven to move away from the hydraulic cylinder 9, and the lower bearing block 19 is driven to rotate, and the other end of the lower bearing block 19 rotates from the current notch to the adjacent notch above the hydraulic cylinder 9. Similarly, under the reaction force of the hydraulic cylinder 9, the upper bearing block 15 in the upper support leg 13 also rotates from the current notch to the necklace notch above the hydraulic cylinder 9, thereby lifting the entire support frame 4 and the drive assembly on the support frame 4 upward by one level. Therefore, by continuously rotating the upper bearing block 15 and the lower bearing block 19 to the next notch, continuous climbing can be achieved.

[0040] The support block 18 acts as a support point, so that the upper support leg 13 and the lower support leg 14 can climb with the support block 18 as the support point. When the climbing assembly climbs to a certain distance, the adsorption assembly and the guide rail 2 that have passed can be disassembled, and the adsorption assembly and the guide rail 2 can be rotated to the remaining path to be passed, so that the climbing to different heights can be realized through rotation.

[0041] It also includes a reversing switch (not shown in the figure), and the connection between the guide rail 2 and the upper supporting leg 13 and the lower supporting leg 14 includes an anti-falling device (not shown in the figure). When the reversing switch is closed, only the upper supporting leg 13 and the lower supporting leg 14 are allowed to climb upward relative to the guide rail 2. When the reversing switch is enabled, the upper supporting leg 13 and the lower supporting leg 14 are allowed to move downward relative to the guide rail.

[0042] refer to Fig.12 and Fig.13 , Fig.12 This is a schematic diagram of the upward climbing process. The figure shows the middle schematic diagram of the climbing process from left to right. From the leftmost side to the rightmost side, the climbing component climbs up several grids (i.e., crosses several notches). Fig.13 This is a schematic diagram of the downward climbing process. The figure shows the middle schematic diagram of the climbing process from left to right. From the leftmost side to the rightmost side, the climbing component climbs down several grids (i.e., crosses several notches).

[0043] Exemplarily, the climbing assembly is also provided with a locking device, which is used to lock the climbing assembly and fix it on the tower column 6, or to unlock and remove the climbing assembly from the tower column 6. When the crane needs to operate, the climbing assembly can be locked on the tower column 6 by the locking device to maintain the stability of the entire device. When it is necessary to ascend or descend, it enters the unlocked state. The locking device can be a bolt or a hydraulic jack. The locking device can achieve a locked state by tightening the support frame 4 against the tower column 6. Conversely, the unlocked state can be achieved by separating the support frame 4 from the tower column 6.

[0044] The present invention can realize the installation of bridge tower columns without relying on traditional super-large lifting equipment or large-tonnage tower cranes. The bridge tower columns are used as the tower columns of the crane. The crane can climb to different heights of the tower columns, and the lifting operation can be realized by the crane, thereby realizing a more economical climbing device that can perform lifting operations and lifting, and has the advantages of good economy, safety, reliability and reusability.
