DETAILED DESCRIPTION

[0043] The present application will be further described below in conjunction with the drawings and specific embodiments:

[0044] As Figures 1-16 shown, the embodiment provides a climbing device for lifting and lowering a crane on an H-shaped bridge tower, which comprises a climbing assembly, a triangle connecting piece 7, a platform truss beam 8 and a suction assembly. The climbing assembly can be sleeved on the tower column 6 of the H-shaped bridge tower to install the climbing assembly on the tower column 6. One end of the triangle connecting piece 7 is connected with the platform truss beam 8, and the triangle connecting piece 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 related devices or components. The other end of the triangle connecting piece 7 is rotationally connected with the climbing assembly, so that the triangle connecting piece 7 can rotate relative to the climbing assembly. The end face of the end of the triangle connecting piece 7 away from the climbing assembly is in a horizontal state, so that the platform truss beam 8 supported by the triangle connecting piece 7 can always be in a horizontal state.

[0045] The tower column 6 of the H-shaped bridge tower can be curved. 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 be adjusted to adapt to the curved direction of the tower column 6. For this purpose, the triangle connecting piece 7 needs to be rotated, so that after the adjustment of the climbing assembly, the end face of the end of the triangle connecting piece 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.

[0046] The climbing assembly can be installed and connected on the tower column 6 through the suction assembly. One end of the suction assembly is connected with the climbing assembly, and the other end of the suction assembly is a free end. That is, when it is needed to be used, the other end of the suction assembly is installed and connected on the tower column 6, so as to install and connect the climbing assembly on the tower column 6. When it is not needed to be used, the other end of the suction assembly can be detached from the tower column 6, and then the climbing assembly is also detached from the tower column 6.

[0047] Exemplarily, the adsorption assembly comprises a male fitting 17 and a female fitting 5, the male fitting 17 and the female fitting 5 are detachably connected, the male fitting 17 is fixedly installed on the climbing assembly, and the female fitting 5 is used to be installed on the tower column 6. The female fitting 5 can be fixedly or detachably installed on the tower column 6, and a plurality of female fittings 5 can be arranged, and each female fitting 5 is arranged at intervals along the extension direction of the tower column 6.

[0048] Exemplarily, the male fitting 17 is a seat plate or a groove pre-excavated on the tower column 6, that is, a reserved groove, and the female fitting 5 is a wall-attached device. The female fitting 5 is embedded on the tower column 6 as a pre-embedded part. The wall-attached device is a prior art, for example, a wall-attached device or a wall-attached frame or a wall-attached connecting assembly commonly used in a tower crane. When the female fitting 5 is a groove, the groove needs to be pre-excavated on the tower column 6, and the movable end of the wall-attached device can be embedded in the groove to stably connect 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-attached device is connected with the seat plate, so that the male fitting 17 is connected with the female fitting 5, and the climbing assembly is connected with the tower column 6 through the adsorption device.

[0049] Exemplarily, the triangular connecting piece 7 is a triangular structure (that is, a triangle), the top corner of the triangular connecting piece 7 is rotationally connected with the climbing assembly, and the bottom side of the triangle abuts against the platform truss beam 8.

[0050] Exemplarily, the triangular connecting piece 7 is connected with the climbing assembly through the rotating shaft 3, the rotating shaft 3 penetrates through the triangular connecting piece 7 and the climbing assembly, so that the triangular connecting piece 7 can rotate relative to the rotating shaft 3.

[0051] Further, a limiting assembly is arranged to limit the upward overturning of the platform truss beam 8. The limiting assembly comprises a clamping rail 11, a rolling bearing 25 and a locking member. The clamping rail 11 is fixedly connected to one end of the platform truss beam 8 close to the triangular connecting member 7. The triangular connecting member 7 is slidably mounted on the clamping rail 11, i.e. the triangular connecting member 7 and the clamping rail 11 can slide relative to each other. The rolling bearing 25 is mounted on the clamping rail 11 and is arranged between the clamping rail 11 and the triangular connecting member 7. The rolling bearing 25 can reduce the resistance when the triangular connecting member 7 and the clamping rail 11 slide relative to each other. The locking member is arranged to release or lock the relative sliding between the clamping rail 11 and the triangular connecting member 7. When the locking member is locked, the relative sliding between the clamping rail 11 and the triangular connecting member 7 is prohibited, i.e. the clamping rail 11 and the triangular connecting member 7 cannot slide relative to each other. When the locking member is released, the relative sliding between the clamping rail 11 and the triangular connecting member 7 is allowed, i.e. the relative sliding can be realized. The locking member can be a bolt. When the relative sliding is needed, the bolt is loosened, so that the triangular connecting member 7 and the clamping rail 11 can slide relative to each other. When the relative sliding is needed to be prohibited, the bolt is tightened, so that the bolt is tightly pressed between the clamping rail 11 and the triangular connecting member 7, thereby fixing the connection between the triangular connecting member 7 and the clamping rail 11 and avoiding the relative sliding between the triangular connecting member 7 and the clamping rail 11, so as to ensure the stability of the whole device when the lifting operation is needed to be performed. The cooperation between the clamping rail 11 and the triangular connecting member 7 can avoid the upward overturning of the platform truss beam 8.

[0052] Further, one end of the platform truss beam 8 is a cantilever end. The crane arranged on the platform truss beam 8 can move to the cantilever end, so that the crane can perform the lifting operation from the side of the platform truss beam 8. The height of the truss of the platform truss beam 8 is increased at the position of the cantilever end, so as to increase the bending resistance of the truss at this position.

[0053] Further, the platform truss beam 8 comprises two parallel and spaced main trusses. The two main trusses are connected by a plurality of transverse beams. In order to avoid the influence of the transverse beams on the climbing, descending or lifting operation of the device, the transverse beams can be connected to the main trusses by bolts, so that the transverse beams at corresponding positions can be removed according to the needs.

[0054] Further, the climbing assembly comprises a support frame 4, a guide rail 2 and a driving assembly arranged on the support frame 4. One end of the adsorption assembly is fixedly connected to the guide rail 2, and the triangular connecting member 7 is connected to the support frame 4. When the adsorption assembly is arranged 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.

[0055] The support frame 4 comprises a support body 41 and a support rotating column 42. The support body 41 comprises an open space 24 for the support frame 4 to be sleeved on the tower column 6, and the open space 24 is provided with an opening. The support rotating column 42 is installed on the side of the support body 41 close to the opening, and is rotatably installed on the support body 41 through a pin shaft 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 with the pin shaft 21, and the other end of the support rotating column 42 is a free end.

[0056] The first position: the support rotating column 42 is located in the opening and closes the opening, so that the open space 24 becomes a closed space.

[0057] The second position: the support rotating column 42 is located outside the opening and makes the opening open, and the open space 24 remains an open space with an opening, that is, a non-closed space.

[0058] Reference is made to Figure 9 and Figure 11 , Figure 9 the support rotating column 42 in Figure 11 is located in the second position.

[0059] By rotating the support rotating column 42 to the first position and the second position respectively, when the climbing assembly climbs to the position of the cross beam 1 on which 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 through (cross) the cross beam 1 on the tower column 6, and the climbing assembly will not be blocked by the cross beam 1. After crossing the cross beam 1, the support rotating column 42 can be rotated to the first position again.

[0060] Illustratively, a plurality of pads 22 are further installed on the support frame 4, and each pad 22 is stacked together, and the pad 22 is located at one end 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, so as to adapt 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.

[0061] Illustratively, the driving assembly comprises a hydraulic oil cylinder 9, an upper support leg 13 and a lower support leg 14. The output end of the hydraulic oil cylinder 9 is connected with the lower support leg 14, and the other end of the hydraulic oil cylinder 9 relative to the output end is connected with the upper support leg 13.

[0062] The upper support leg 13 comprises an upper support frame (not shown in the figure) and an upper bearing block 15 and an upper stop block 16 mounted on the upper support frame, the upper support frame is slidably mounted on the guide rail 2, the upper stop block 16 is arranged along the axial direction of the guide rail 2, that is, vertically arranged, and the upper stop block 16 is arranged in parallel and spaced apart from the guide rail 2. One end of the upper bearing block 15 is connected with the upper stop block 16, the upper bearing block 15 is rotatable, and the other end of the upper bearing block 15 is movably abutted on the guide rail 2.

[0063] The lower support leg 14 comprises a lower support frame (not shown in the figure) and a lower bearing block 19 and a lower stop block 20 mounted on the lower support frame, the lower support frame is slidably mounted on the guide rail 2, the lower stop block 20 is arranged along the axial direction of the guide rail 2, that is, vertically arranged, and the lower stop block 20 is arranged in parallel and spaced apart from the guide rail 2. One end of the lower bearing block 19 is connected with the lower stop block 20, the lower bearing block 19 is rotatable, and the other end of the lower bearing block 19 is movably abutted on the guide rail 2.

[0064] The guide rail 2 comprises 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 (that is, the extension direction) of the support bar, and a notch is formed between adjacent two support blocks 18. The other end of the upper bearing block 15 and the other end of the lower bearing block 19 are both extended into the notch.

[0065] During the rotation of the upper bearing block 15 and the lower bearing block 19, the upper bearing block 15 and the lower bearing block 19 can be rotated from the current notch to the adjacent next notch, so as to realize climbing or descending.

[0066] Taking upward climbing (that is, ascending) as an example, when climbing is needed, the hydraulic oil cylinder 9 is started, when the output end of the hydraulic oil cylinder 9 is extended outward, the lower support leg 14 is driven to move away from the direction of the hydraulic oil cylinder 9, and the lower bearing block 19 is rotated, the other end of the lower bearing block 19 is rotated from the current notch to the adjacent notch above the hydraulic oil cylinder 9. Similarly, under the reaction force of the hydraulic oil cylinder 9, the upper bearing block 15 in the upper support leg 13 is also rotated from the current notch to the adjacent notch above the hydraulic oil cylinder 9, so as to lift the entire support frame 4 and the driving assembly on the support frame 4 upward by one step. Thus, by continuously rotating the upper bearing block 15 and the lower bearing block 19 to the next notch, continuous climbing can be realized.

[0067] Among them, the support block 18 plays the role of a support point, so that the upper support leg 13 and the lower support leg 14 can realize climbing with the support block 18 as the support point. After the climbing assembly climbs to a certain distance, the adsorption assembly and the guide rail 2 that have passed through can be disassembled, and the adsorption assembly and the guide rail 2 are rotated to the remaining path to be passed through, so that continuous climbing to different heights can be realized through rotation.

[0068] Wherein, the connection of the guide rail 2 and the upper support leg 13 and the lower support leg 14 comprises a falling prevention device (not shown in the figure), in the off state of the reversing switch, only the upward climbing of the upper support leg 13 and the lower support leg 14 relative to the guide rail 2 is allowed, and in the on state of the reversing switch, the downward movement of the upper support leg 13 and the lower support leg 14 relative to the guide rail is allowed.

Figure 13 is a schematic diagram of the downward climbing process, in which the middle schematic diagram of the climbing process is shown from left to right, and the climbing assembly has climbed several steps (i.e. has crossed several notches) from the leftmost side to the rightmost side.

[0070] Illustratively, the climbing assembly is further provided with a locking device for locking the climbing assembly on the tower column 6 or releasing the locking so that the climbing assembly can be detached from the tower column 6. When the crane needs to work, the locking device can be used to lock the climbing assembly on the tower column 6 to maintain the stability of the whole device. When it is necessary to rise or descend, the unlocking state is entered. The locking device can be a bolt or a hydraulic jack, and the locking device can be in the locking state by pressing the support frame 4 against the tower column 6, and vice versa, the support frame 4 is separated from the tower column 6, and the unlocking state is achieved.
