Its rapid development trend has also laid a solid market foundation for the widespread use of attached lifting scaffolds, forming attached lifting scaffolds (referred to as climbing frames).

[0045] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. Each example is provided by way of explanation of the present application and does not limit the present application. In fact, it will be clear to those skilled in the art that modifications and variations may be made in the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as a part of an embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the embodiments of the present invention should belong to the scope of protection of the embodiments of the present invention.

[0046] At present, under the condition of high floor height, scattered steel columns are usually assembled on the construction floor by tower crane. After the steel columns are assembled and fixed on the construction floor, the climbing frame is fixed on the steel columns to carry out construction on the construction floor. The whole process not only requires the full cooperation of the tower crane, but also the on-site disassembly and assembly of the steel columns by the workers, which inevitably increases the labor intensity and safety risks of the workers.

[0047] Based on this, the present application provides a self-lifting attachment device for a climbing frame with super-high net height of a floor, such as Figures 1 to 17As shown, the automatic climbing frame device includes: a lifting unit 100, a climbing frame unit 400 and a foldable steel column 300. The lifting unit 100 is installed on the top of the main frame of the target building of the construction, and is used to lift the climbing frame unit 400; the climbing frame unit 400 is arranged in parallel to the side of the wall of the target building, and is connected to the lifting unit 100 through a lifting truss 402, so as to move in the vertical direction under the action of the lifting unit 100; the foldable steel column 300 is detachably connected to the climbing frame unit 400, and the bottom surface is located on the bottom plate of the construction layer of the target building in the unfolded state, so as to support the climbing frame and facilitate the construction of the workers; in the folded state, it moves upward to the next construction layer together with the climbing frame unit 400. In this way, the foldable steel column 300 cooperates with the climbing frame. During construction, the foldable steel column 300 is unfolded and supported along with the climbing frame. During transfer, the foldable steel column 300 is transferred together with the climbing frame. After the transfer, only the foldable steel column 300 needs to be unfolded to carry out construction, and a tower crane is no longer needed to cooperate with the lifting throughout the process. While improving construction efficiency, the construction cost is effectively reduced.

[0048] In a specific example, the lifting unit 100 includes an electric hoist and a hanging member, wherein the hanging member is fixed to the structural concrete with M30 bolts, and the concrete strength of the floor where the hanging member is located is not less than C20, the M30 bolts are inserted from the outside of the wall, and a gasket and two nuts are installed on the inside for fixing; after the hanging member is fixed, the electric hoist is fixed to the hanging member, the lifting truss 402 is hooked by a sling or a ring, and the chain is tightened to keep the force on each electric hoist consistent.

[0049] In a specific example, the climbing frame unit 400 includes two reinforced guide rails 401 arranged symmetrically along the width direction and extending along the vertical direction. The two reinforced guide rails 401 are connected by a lifting truss 402, and the lifting truss 402 is hooked and connected to the hook of the electric hoist. Among them, the reinforced guide rail 401 includes: a sliding rod 411, a limiting rod 421, a transverse connecting rod 431 and a climbing frame connecting part 441. The cross section of the sliding rod 411 is circular, and there are two sliding rods 411, and multiple limiting rods 421 are evenly distributed in parallel between the two sliding rods 411; one end of the transverse connecting rod 431 is connected to the middle of the limiting rod 421, and the other end is connected to the climbing frame connecting part 441. Here, the climbing frame connection part 441 is connected to the limit rod 421 through multiple groups of transverse connecting rods 431 arranged in parallel along the vertical direction, each group of transverse connecting rods 431 has multiple transverse connecting rods 431, and the multiple transverse connecting rods 431 of the same group are respectively connected to the corresponding multiple limit rods 421 in a one-to-one correspondence. It should be noted that the sliding rod 411 and the climbing frame connection part 441 are both extended in the vertical direction, and the limit rod 421 and the horizontal connecting rod are both arranged in the horizontal direction and are perpendicular to each other.

[0050] The hoisting truss 402 is detachably connected between the two climbing frame connecting parts 441 of the two reinforcing guide rails 401, and the two ends of the hoisting truss 402402 are detachably connected to the two climbing frame connecting parts 441 through bolt fasteners. After the climbing frame unit 400 is connected to the foldable steel column 300, the foldable steel column 300 is located on the construction layer to support the climbing frame; when transferring, the climbing frame unit 400 and the folded foldable steel column 300 are lifted as a whole through the lifting unit 100.

[0051] In this embodiment, the climbing frame unit 400 is also supported and limited by a limiting support unit. Specifically, the limiting support unit is installed on the main frame of the i-th floor of the target building, and is respectively adapted to the two reinforcing rails 401, and after the climbing frame unit 400 is lifted to a predetermined position, the reinforcing rails 401 are provided with limiting support. The limiting support unit includes a plurality of attachment supports 200, which are divided into two groups along the width direction and symmetrically installed on the main frame of the i-th floor of the target building, and are used to provide limiting support for the reinforcing rails 401.

[0052] Specifically, in the construction state, two groups of attachment supports 200 arranged symmetrically along the width direction and the foldable steel column 300 in the unfolded state are used to limit the position of the climbing frame unit 400, so as to facilitate the construction work of the workers; in the transfer, two groups of attachment supports 200 arranged symmetrically along the width direction are used to limit the overall movement of the climbing frame unit 400 and the foldable steel column 300 in the folded state in the width direction, so as to avoid the lateral displacement of the overall movement of the climbing frame unit 400 and the foldable steel column 300 in the folded state. Through the same group of multiple attachment supports 200 arranged in parallel along the vertical direction, the overall movement of the climbing frame unit 400 and the foldable steel column 300 in the folded state is guided in the height direction, so as to avoid the overall movement of the climbing frame unit 400 and the foldable steel column 300 in the folded state from tilting outward; thus, the directional movement of the climbing frame unit 400 and the foldable steel column 300 in the vertical direction is realized.

[0053] When installing the attachment support 200, first, insert the high-strength bolt M30 into the reserved hole of the structure, then connect the attachment support 200 to the two M30 high-strength bolts arranged in parallel along the width direction, and connect and tighten them through the gasket nut. Each attachment support 200 includes: a support body 201, a limit support unit and a rolling support unit 204. The support body 201 includes a connecting plate and a mounting platform, the connecting plate and the mounting platform are perpendicular to each other, and a waist-shaped hole is provided on the connecting plate in the width direction to connect with the two embedded bolts (M30 high-strength bolts) arranged in parallel along the width direction on the construction body, so that the support body 201 is fixed on the construction body.

[0054] The installation platform is connected to the connecting plate and is used to install the limit support unit and the rolling support unit 204. Among them, the reinforcing guide rail 401 is slidably mounted inside the rolling support unit 204, so that the reinforcing guide rail 401 moves in the vertical direction driven by the electric hoist. Here, it should be noted that during the transfer process, the attachment support 200 is installed at the same time on the completed i+1th floor. The limit support unit of the attachment support 200 of the i+1th floor can provide limit support for the reinforcing guide rail 401 after the climbing frame is lifted to the predetermined position, so that the climbing frame unit 400 is fixed; then, the foldable steel column 300 in a folded state is unfolded and located on the construction layer (i+2th floor), and the attachment support 200 of the i-th floor is removed.

[0055] Specifically, the limit support unit includes: an upper limit assembly 202 and a lower limit assembly 203, which are arranged in parallel along the vertical direction, and the upper limit assembly 202 is rotatably connected to the support ear plate provided on the upper surface of the installation platform; the lower limit assembly 203 is installed in the limit installation cavity provided on the lower surface of the installation platform. Among them, the upper limit assembly 202 provides limit support to the reinforced guide rail 401 through manual adjustment after the climbing frame unit 400 is lifted to the predetermined position, and the lower limit assembly 203 automatically provides limit support to the reinforced guide rail 401 after the climbing frame unit 400 is lifted to the predetermined position.

[0056] In this embodiment, the upper limit assembly 202 includes: a rotating connection part, a double-headed adjustment stud and a support part. The rotating connection part is rotatably connected to the support ear plate, and includes: two rotating connection plates arranged in parallel and a first adjustment nut located between the two rotating connection plates, the first adjustment nut is located at one end of the rotating connection shaft away from the rotating connection plate and the support ear plate; and a rotating reinforcement plate is also used between the two rotating connection plates for structural reinforcement.

[0057] The support part includes two support plates arranged in parallel and a second adjusting nut located between the two support plates. The upper end of the support plate is provided with an arc-shaped support surface adapted to the support part of the reinforced guide rail 401, that is, the arc-shaped support surface is adapted to the limit rod 421, so that after the climbing frame unit 400 moves into place, the arc-shaped support surface provides limit support to the limit rod 421.

[0058] One end of the double-headed adjusting stud is threadedly connected to the first adjusting nut, and the other end is threadedly connected to the second adjusting nut located at the lower ends of the two support plates, wherein the thread rotation directions at both ends of the double-headed adjusting stud are different. By rotating the double-headed adjusting stud, the relative distance between the first adjusting nut and the second adjusting nut can be adjusted, so that the arc-shaped supporting surface can be pressed against the limit rod 421 or accelerated to separate from the limit rod 421.

[0059] In this embodiment, the lower limit assembly 203 includes: a limit support block 213 and a limit paddle 233. The limit support block 213 is rotatably mounted in the limit installation cavity, and the upper surface of the limit support block 213 is pre-tightened and connected to the inner side wall of the limit installation cavity through a tension spring 223. Specifically, a spring mounting plate is provided in the limit installation cavity, one end of the tension spring 223 is connected to the welding nut on the spring mounting plate, and the other end is connected to a pull ring provided on the upper surface of the limit support block 213, so that when no external force is applied, under the action of the tension spring 223, the upper end of the limit support block 213 has a tendency to rotate upward, and is always pulled toward the limit installation cavity.

[0060] The limit paddle 233 is rotatably connected to the limit ear plate arranged at the lower part of the limit support plate through a torsion spring, so that, when not subjected to external force, under the action of the torsion spring, the upper end of the limit paddle 233 always has a tendency to rotate downward, that is, it rotates in a direction away from the limit installation cavity and close to the reinforced guide rail 401. During the lifting process of the climbing frame unit 400, due to the spacing between two adjacent limit rods 421, the upper end of the limit paddle 233 intermittently contacts the limit rod 421 of the reinforced guide rail 401. When the limit paddle 233 contacts the limit rod 421, under the action of the reinforced guide rail 401 (the reinforced guide rail 401401 moves upward), the upper end of the limit paddle 233 is driven to rotate upward, that is, rotate toward the limit installation cavity; when the limit paddle 233 is out of contact with the current limit rod 421, the limit paddle 233 is reset under the action of the torsion spring, that is, the lower end of the limit paddle 233 abuts against the lower part of the limit support block 213.

[0061] After the climbing frame unit 400 is lifted to the predetermined position, before the limiting support unit provides limiting support to the reinforced guide rail 401, the climbing frame unit 400 has a tendency to move downward; the lower surface of the limiting rod 421 above the limiting paddle 233 contacts the upper end of the limiting paddle 233, and the upper end of the limiting paddle 233 rotates downward under the action of the limiting rod 421 of the reinforced guide rail 401, that is, rotates toward the reinforced guide rail 401, so that the lower end of the limiting paddle 233 is pressed against the limiting support block 213, thereby driving the lower end of the limiting support block 213 to rotate upward, even if the lower end of the limiting support block 213 rotates downward, it moves toward the limiting rod 421 of the reinforced guide rail 401, so that the upper end of the limiting support block 213 is inserted between two adjacent limiting rods 421, thereby realizing limiting support for the reinforced guide rail 401.

[0062] In this embodiment, a limit baffle is further provided in the limit installation cavity to limit the rotational travel of the limit support block 213 so that the limit support block 213 can effectively provide limit support to the reinforcing guide rail 401 .

[0063] In this embodiment, the rolling support unit 204 includes two groups of roller groups symmetrically arranged along the width direction, and each group of roller groups includes two cone-shaped rollers symmetrically arranged along the length direction; correspondingly, two roller installation cavities are symmetrically arranged along the width direction according to the lower surface of the platform, and two groups of roller groups are respectively installed in the two roller installation cavities. The two roller groups are respectively adapted to the two sliding rods 411 of the reinforcing guide rail 401, and the two cone-shaped rollers in each group of roller groups perform rolling guide limit and overturning limit on one sliding rod 411. Furthermore, the small ends of the cone-shaped rollers in the two groups of roller groups are arranged face to face, so as to realize the automatic centering of the reinforcing guide rail 401 during the vertical movement, and further avoid the lateral displacement of the reinforcing guide rail 401 along the width direction.

[0064] In this embodiment, the attachment support 200 is installed and fixed by inserting M30 high-strength bolts into the reserved holes of the structure, and the lifting truss 402 is connected between the two reinforced guide rails 401 by bolt fasteners. After each bolt is installed, it is checked by a torque wrench.

[0065] Thus, the foldable steel column 300 and the limit support unit cooperate with each other to achieve the limit, support and fixation of the climbing frame unit 400 in the construction state; after the construction of the i+1th floor of the target building is completed, the limit support unit is installed on the i+1th floor, and the climbing frame unit 400 and the foldable steel column 300 are lifted upward together by the lifting unit 100. At the same time, the movement of the climbing frame unit 400 and the foldable steel column 300 is guided by the limit support units installed on the i-th floor and the i+1th floor. After the climbing frame unit 400 and the foldable steel column 300 move to the i+2th floor and the foldable steel column 300 is unfolded and seated on the bottom plate of the i+2th floor, the limit support unit of the i-th floor is removed. After the transfer, only the foldable steel column 300 needs to be unfolded to carry out the construction, and the tower crane is no longer required to cooperate with the lifting throughout the process. While improving the construction efficiency, it effectively reduces the construction cost.

[0066] In another specific example, the foldable steel column 300 includes: a fixed frame 301, a horizontal connecting rod 302 and a folding support rod 303. There are two fixed frames 301, which are arranged in parallel; there are multiple horizontal connecting rods 302, which are evenly distributed on the two fixed frame 301 brackets along the vertical direction, and the two ends of each horizontal connecting rod 302 are respectively rotatably connected to the two fixed frames 301; the two ends of the folding support rod 303 are respectively rotatably connected to the two fixed frames 301, and the folding support rod 303 is provided with a support limiter, which is used to limit the relative movement between the two fixed frames 301 when the foldable steel column 300 is in the unfolded state. Thereby, the structural strength of the foldable steel column 300 is enhanced by the horizontal connecting rod 302, and the relative movement between the two fixed frames 301 of the foldable steel column 300 in the unfolded state is limited and supported by the folding support rod 303, so that the two fixed frames 301 are relatively fixed, thereby effectively enhancing the structural stability of the foldable steel column 300 in the unfolded state.

[0067] In this embodiment, the fixed frame 301 includes: a vertical fixed rod 311 and a horizontal fixed rod 321. There are two vertical fixed rods 311, which are arranged in parallel and extend in the vertical direction; there are multiple horizontal fixed rods 321, which are evenly distributed between the two vertical fixed rods 311 in the vertical direction, and the two ends of each horizontal fixed rod 321 are fixedly connected to the two vertical fixed rods 311. Further, the foldable steel columns 300 are made of profiles (such as H-shaped steel) to further reduce the processing and manufacturing costs of the foldable steel columns 300.

[0068] The folding support rod 303 is a telescopic sliding structure, and is connected between two fixed frames 301 along an oblique support; a folding support rod 303 is arranged between two adjacent horizontal connecting rods 302, and the angle between the folding support rod 303 and the two horizontal connecting rods 302 is an acute angle, so as to further enhance the position-limiting support of the folding support rod 303 on the fixed frames 301. Specifically, the folding support rod 303 includes: a fixed rod and a sliding rod 411, one end of the fixed rod is rotatably connected to a fixed frame 301, one end of the sliding rod 411 is slidably inserted into the other end of the fixed rod, and the other end of the sliding rod 411 is rotatably connected to the other fixed frame 301. Among them, limit locking holes are respectively provided at one end of the fixed rod and the sliding rod 411 that are slidably inserted with each other. When the foldable steel column 300 is unfolded, the limit pin shaft is inserted into the limit locking holes directly opposite to the fixed rod and the sliding rod 411 to lock the fixed rod and the sliding rod 411, so that the fixed rod and the sliding rod 411 no longer have relative movement, thereby enhancing the structural stability of the foldable steel column 300 in the unfolded state.

[0069] At the same time, the foldable steel column 300 is further stabilized by a fixed zipper that is tightened diagonally. Specifically, one end of the fixed zipper is connected to the foldable steel column 300, and the other end is detachably connected to the bottom plate of the i+1th floor of the target building to tighten the foldable steel column 300 diagonally in the unfolded state.

[0070] The automatic climbing device of the embodiment of the present application can be automatically lifted according to construction requirements, greatly improving construction efficiency and speed. Moreover, the installation can better adapt to different construction environments and working conditions.
