[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0036] In view of the technical problem of low construction efficiency caused by the existing welding construction platform, based on this technical problem, the present invention provides a self-climbing welding platform for super-high-rise special-shaped steel columns, which can have the ability to climb along and at the same time have a certain obstacle-crossing ability. And after the welding platform is lifted in place, it can quickly complete the transformation from the lifting state to the fixed state, quickly complete the rearrangement and enter the next construction process, greatly improving the construction efficiency.

[0037] See Figure 1 , the self-climbing welding platform provided by this solution includes a main structure 100, a movable connection mechanism 200 and a lifting mechanism 300.

[0038] The main structure 100 is used for construction workers to stand on. Therefore, the main structure 100 preferably uses square steel pipes as the main load-bearing components to ensure the rigidity of the main structure.

[0039] See Figure 2 , the main structure 100 includes three platforms, namely a large broken-line platform 110 and two small arc-shaped platforms 120 / 130. Fences 160 are provided on the three platforms to protect the personal safety of construction workers; these three platforms are spliced together by setting three groups of movable connection mechanisms 200 to form a main structure 100 similar to an ellipse.

[0040] A manhole 140 for construction workers to climb onto the platform is provided on one of the small arcs. The manhole 140 is connected with a ladder 150, which can facilitate construction workers to climb onto the platform through the ladder 150 and the manhole 140.

[0041] The three sets of movable connection mechanisms 200 have the same structure and each includes two sets of connection components, which are respectively arranged at the connection of the fences 160 of the two platforms and at the connection of the floors of the two platforms.

[0042] The connection components can be controlled remotely. Without the presence of personnel, the remote control can be used to open and lock the connection components.

[0043] See Figure 3 , the connection component includes a motor 250, a swing arm 210, a locking plate 220, a target rod 230 and a push rod 240.

[0044] One end of the swing arm 210 is cooperatively connected with the motor 250 and is rotatably arranged on one platform at the connection of the two platforms. The other end is provided with a locking plate 220, and an opening slot 222 and a closing hole 221 are formed on the locking plate 220.

[0045] The target rod 230 is arranged on the end face of the other platform at the connection of the two platforms, and at the same time, the push rod 240 is arranged on the side of the other platform.

[0046] See Figure 3 - Figure 4 , when the swing arm 210 is driven by the motor 250, the locking plate 220 on the swing arm 210 can be rotated to the target rod 230, and the target rod 230 is grabbed through the opening slot 222 on the locking plate 220. After grabbing the target rod 230, the push rod 240 passes through the closing hole 221 of the locking plate 220 to achieve the effect of locking the platform to prevent it from falling off; at the same time, the opposite operation can achieve the effect of unlocking the platform.

[0047] At the same time, a channel-shaped guard plate 231 is welded to the target rod 230 to further ensure that the target rod 230 will not come out of the swing arm and to transfer the bending moment.

[0048] In addition, through the locking and unlocking of this movable connection mechanism 200, the three platforms can be disassembled, and "ship lock type" obstacle crossing can be achieved during the rising process of the platform.

[0049] Specifically, see Figure 5 - Figure 6 , when the self-climbing welding platform is being lifted by the lifting device and encounters a steel beam 400 that has already been installed, the swing arm 210 on the fence will be unlocked and opened first. At this time, the swing arm 210 on the platform floor remains locked.

[0050] Continue to lift the platform so that the steel beam 400 enters between the upper and lower swing arms 210 of the platform fence 160. At this time, close and lock the swing arm 210 on the fence 160, unlock and open the swing arm 210 on the platform floor and continue to lift the platform until the steel beam 400 passes through the lower side of the platform. At this time, the lower swing arm 210 can be closed and locked to complete the obstacle crossing.

[0051] The lifting mechanism 300 can be controlled remotely, enabling remote control of the lifting mechanism for lifting without personnel on site.

[0052] The lifting mechanism 300 includes several groups of lifting components, which are respectively arranged at equal intervals at the large broken-line platform 110 and the corresponding ends of the two small arc-shaped platforms 120 / 130 and the large broken-line platform 110.

[0053] In this solution, it is preferably to use five groups of lifting components, among which three are respectively arranged at equal intervals on the large broken-line platform 110, and two are respectively arranged at one end of the two small arc-shaped platforms 120 / 130. Distributed on the main structure 100 through this structure, it can ensure that the main structure 100 can be evenly stressed during lifting, enabling the main structure 100 to be lifted stably.

[0054] See Figure 7 , each group of lifting components includes a fixed pulley 320 and a winch 310.

[0055] The winch 310 is arranged on the bottom plate of the main structure 100 according to the distribution position of the lifting components. The fixed pulley 320 is correspondingly arranged on the ear plate of the target column 600 at the top, and the fixed pulley 320 is connected to the middle of the ear plate.

[0056] See Figure 8 , then pass the steel wire rope 321 on the winch 310 through the fixed pulley 320 and hook it on the platform bottom plate. The steel wire rope 321 is wound and unwound by the forward and reverse rotation of the winch 310 to lift and lower the main structure 100.

[0057] The number of winches 310 is not limited to five here. The specific quantity and distribution need to refer to the position of the reserved ear plates on the target column 600 and should be correspondingly arranged with the reserved ear plates on the target column 600.

[0058] In addition, an encoder is also provided in cooperation with the winch 310. The telescopic length of the steel wire rope 321 is read by the encoder set on each winch 310 and fed back to the host in the control box. The host coordinates the rotation speed of each winch 310 through the feedback data.

[0059] When there is a small speed difference, the host will automatically coordinate and balance the rotation speeds of each winch 310. When the speed difference is too large, the platform will stop lifting.

[0060] A solution that can ensure the stability of the platform during lifting by controlling and coordinating the lifting speeds of each winch 310 through the encoder by equipping the winch 310 with an encoder.

[0061] Secondly, a safety component is also provided on the main body structure. The safety component includes a fall arrester 330. The fall arrester 330 and the fixed pulley 320 are correspondingly arranged at the end of the ear plate of the target column 600. A fall arrester rope 331 is provided on the fall arrester 330 and is directly pulled down and hooked on the bottom plate of the main body structure 100. It can perform emergency anti-fall locking on the welding platform when the lifting mechanism makes a mistake, and is used to further protect the safety of the welding platform.

[0062] Before the self-climbing welding platform switches from the fixed mode on the original steel column to the lifting mode of climbing to a new steel column, it is necessary to first wind the steel wire rope 321 on the hoist 310 around the fixed pulley 320 on the new steel column and pull it back and fix it on the shackle fixed on the bottom plate of the welding platform. In the traditional construction method, construction workers need to climb to the top of the column to operate in this step. To ensure the safety of construction workers, this solution designs a set of solutions for replacing the steel wire rope for the top pulley without climbing:

[0063] (1) Refer to Figure 9 , pre-install the fixed pulley 320 and the fall arrester 330 for the new steel column on the ground. At this time, the fall arrester rope 331 of the fall arrester 330 is retracted inside the fall arrester 330. The double-headed hooked second traction belt 800 with a length twice the height of a single column is pre-passed through each fixed pulley 320, and the lengths of the second traction belt 800 left on both sides of the fixed pulley 320 are equal. Connect the hook on one side of the double-headed hooked first traction belt 700 with a length equal to the height of a single column to the hook of the fall arrester 330.

[0064] (2) Refer to Figure 10 , hoist the main body equipped with the fixed pulley 320, the fall arrester 330 and the traction belt to the construction height to be. At this time, pull the pre-passed first traction belt 700, and the fall arrester rope 331 in the fall arrester 330 can be pulled out until the corresponding connection part of the platform. At this time, remove the first traction belt 700 on the fall arrester rope 331 in the fall arrester 330, and directly connect the fall arrester 330 to the platform.

[0065] (3) Refer to Figure 11 , hook the second traction belt 800 pre-passed through the fixed pulley 320 to the side corresponding to the outlet of the steel wire rope 321 of the hoist 310 and hook it to the steel wire rope 321 of the hoist 310.

[0066] (4) Refer to Figure 12 , pull the other side of the second traction belt 800 to make the second traction belt 800 drive the steel wire rope 321 of the hoist 310 to pass through the fixed pulley 320 and then return to the connection buckle of the steel wire rope 321 of the hoist 310. At this time, remove the second traction belt 800, and connect the steel wire rope of the hoist 310 to the corresponding connection buckle, completing the process of replacing the steel wire rope 321 for the fixed pulley 320 without climbing.

[0067] Furthermore, when the platform climbs to the destination, it is necessary to fix the platform. Therefore, a rotary connection mechanism is arranged at the bottom of the platform, which can be fixedly connected to the target cylinder 600 through rotation.

[0068] The rotary connection mechanism includes several groups of rotary connectors. The several groups of rotary connectors are distributed on the mounting plate where the winch 310 on the platform is located, and can be cooperatively connected with the ear plates on the target cylinder 600, so as to connect the platform and the target cylinder 600 for welding work.

[0069] See Figure 13 , the rotary connector can be a rotary connecting rod. One end of the rotary connecting rod 510 is hinged to the mounting plate where the winch 310 is located through a hinge structure, and can rotate around this hinge structure relative to the ear plate of the target cylinder 600.

[0070] The other end of the rotary connecting rod 510 can be rotated to the ear plate of the target cylinder 600 and connected to the ear plate through a pin, so as to realize the connection between the main body structure 100 and the target cylinder 600.

[0071] When the self-climbing welding platform is lifted to the construction operation surface, the rotary connecting rod 510 is fixed to the ear plate of the target cylinder 600 through a pin, the fixing of the steel wire rope 321 on the operation platform is cancelled, and the anti-falling device 330 and the fixed pulley 320 are removed. At this time, the next section of special-shaped steel column can be hoisted to the welding position and fixed by a temporary clamping plate, and then welding work can be carried out.

[0072] In addition, the rotary connector here is not limited to a rotary connecting rod, and a connecting plate with one end hinged to the mounting plate of the winch 310 can also be used. The other end of the connecting plate can be rotated to the ear plate and connected to the ear plate through a pin, so as to realize the connection between the main body structure 100 and the target cylinder 600.

[0073] There is no limitation on the specific structure of the rotary connector here, and it can be determined according to the actual situation.

[0074] In view of the problem that the column welding platform used in the construction process of the traditional super high-rise core tube outer frame column must rely on the tower crane for transfer, resulting in the steel column welding construction speed being affected by the tower crane scheduling and the inconvenient use and low efficiency, this solution proposes a new type of self-climbing welding construction platform. The welding platform can climb on the ear plates reserved on the wall of the special-shaped steel column, uses the winch as the power source, and uses the encoder to read and coordinate the lifting speeds of each winch to ensure the stability of the platform.

[0075] At the same time, see Figure 14 - Figure 15, when the platform encounters a steel beam that has been installed in place above it during the lifting process, a "ship lock type" obstacle-crossing solution can be adopted. By alternately unlocking and locking the connecting swing arms, the effect of passing through the structural beam can be achieved, so that the use of the welding platform does not affect the construction of other processes.

[0076] And during the whole process of lifting and obstacle crossing, a remote control device can be used to operate at a safe position, and an operation plan for replacing the steel cable of the crown block pulley without climbing is formulated, which comprehensively ensures the safety of construction personnel. After the welding platform is lifted in place, the transformation from the lifting state to the fixed state can also be quickly completed, and the rearrangement can be quickly completed to enter the next construction process.

[0077] This solution can solve the core problem that the existing construction platform needs to rely on a tower crane during the transfer process and cannot cross obstacles through the already installed beams, greatly improving the construction efficiency of the welding platform.
