Description

Technical Field

[0001] This invention relates to the field of construction equipment, and more specifically to a climbing mechanism for a building construction machine. Background Technology

[0002] In the field of high-rise building construction, the aerial building machine is a large-scale intelligent equipment platform that integrates a factory-style construction model into the construction site. Supported by a hydraulic climbing mechanism, the platform completes processes such as rebar tying, formwork erection, and concrete pouring layer by layer. The climbing mechanism is the core load-bearing and lifting component of the building machine, responsible for bearing all construction loads and enabling the platform's vertical ascent.

[0003] Chinese Patent CN 118855216 A discloses a reciprocating climbing support column for a building construction machine and a climbing process, including an outer column and an inner column set inside the outer column. The lower end of the inner column is provided with a lifting mechanism for climbing the inner column. The upper ends of the inner column and the outer column are respectively provided with several sets of wall attachment nodes. The inner column and the outer column are detachably connected to the wall through the wall attachment nodes. The upper end of the inner column is provided with an upper beam support leg, and the building construction machine is set on the upper beam support leg. The vertical lifting of the construction platform is realized through the reciprocating climbing of the column.

[0004] However, in practical applications, existing climbing mechanisms involve the entire inner sleeve column (and upper truss platform) rising during the hydraulic cylinder lifting phase. The height of each part of the lifting column continuously changes. To ensure construction safety, a dedicated observer is assigned to each lifting column. However, the observer must adjust their position in real time according to the lifting direction, resulting in periods of interrupted visibility during the lifting process. This makes the on-site confirmation of the safe completion of each lifting step less intuitive and clear, posing a risk of information lag. Overall construction safety needs further improvement, and the risk of safety accidents caused by the loss of visual observation is increased, resulting in a relatively high failure rate. Furthermore, the existing climbing mechanism has a relatively long overall structural length. The outer sleeve column in the existing scheme is a single structure, requiring guidance and support along the entire length of the inner sleeve column. The long overlap between the two in the axial direction results in a large total column height, increasing manufacturing costs and the difficulty of transportation and installation.

[0005] Therefore, how to effectively improve the safety of jacking construction, so that dedicated observers for each jacking column can maintain full visual coverage of the jacking column without changing their positions, and at the same time reduce the overall structural height of the jacking column to facilitate transportation and installation, has become an urgent problem to be solved in this field. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a safe, reliable, easy-to-transport and easy-to-install climbing mechanism and climbing process for building construction machines.

[0007] To achieve the above objectives, the present invention provides a climbing mechanism for a building construction machine, comprising an inner tube assembly and a driving device, and further comprising an outer tube assembly. The outer tube assembly includes a first outer tube assembly and a second outer tube assembly that are independent of each other and sequentially arranged along the axial direction of the inner tube assembly. The first outer tube assembly and the second outer tube assembly are slidably sleeved on the inner tube assembly. The driving device is connected between the first outer tube assembly and the second outer tube assembly and can drive the first outer tube assembly and the inner tube assembly to move relative to each other in a lifting motion. The first outer tube assembly and the second outer tube assembly can be locked or unlocked alternately with the inner tube assembly, and the inner tube assembly is gradually lifted under the drive of the drive device. During the lifting process, the displacement range of the outer tube assembly relative to the inner tube assembly does not exceed one stroke of the drive device. The drive device can also drive the first outer tube assembly and the second outer tube assembly to move alternately along the inner tube assembly after the inner tube assembly is lifted into place, so as to adjust the installation position of the outer tube assembly on the inner tube assembly and follow the inner tube assembly to climb.

[0008] Furthermore, the inner tube assembly has a plurality of force-bearing holes spaced apart on its sidewall; both the first outer tube assembly and the second outer tube assembly include a limiting plate and a handle, the handle being used to control the limiting plate to engage or disengage from the force-bearing holes of the inner tube assembly.

[0009] Furthermore, the limiting plate is hinged to the corresponding outer tube assembly via a pin. The outer tube assembly also includes a spring. The spring can drive the limiting plate to engage in the force-receiving hole, and the handle can overcome the spring force to push the limiting plate out of the force-receiving hole.

[0010] Furthermore, the inner tube assembly is configured as a rectangular cross-section tube, and several guide wheels are installed on the inner walls of both the first outer tube assembly and the second outer tube assembly. The guide wheels are in rolling contact with the four outer edges of the rectangular cross-section tube.

[0011] Furthermore, the first outer tube assembly, the second outer tube assembly, and the inner tube assembly are all provided with wall attachment nodes, which extend out and attach to mating holes on the wall.

[0012] Furthermore, the wall attachment node includes a bracket, the tail of which is provided with a set screw, and a bracket limiting block is provided on the corresponding outer tube assembly or inner tube assembly at the position corresponding to the tail of the bracket; when the bracket extends out and is attached to the wall mating hole, the set screw can press against the bracket limiting block.

[0013] Furthermore, the wall attachment node also includes an anti-deviation screw and a top wall nut rod, which are mounted on the second outer sleeve assembly and the inner sleeve assembly.

[0014] To achieve the above objectives, the present invention provides a climbing process for a building construction machine, based on the aforementioned climbing mechanism for the building construction machine, the climbing process comprising: Inner tube lifting stage: Release the wall attachment of the inner tube assembly and release the lock between the second outer tube assembly and the inner tube assembly; control the drive device to lift, causing the inner tube assembly to rise one stroke; lock the second outer tube assembly and the inner tube assembly, and unlock the first outer tube assembly and the inner tube assembly; control the drive device to retract, causing the first outer tube assembly to descend and reset; alternately switch the locking states of the first outer tube assembly and the second outer tube assembly with the inner tube assembly, repeating the lifting and resetting steps until the inner tube assembly reaches the target height, and reattach and fix the inner tube assembly to the wall, with the displacement range of the outer tube assembly relative to the inner tube assembly not exceeding one stroke of the drive device; Outer tube follow-up stage: Attach the first outer tube assembly to the wall and release the second outer tube assembly from the wall; control the drive device to retract, causing the second outer tube assembly to rise one stroke; attach the second outer tube assembly to the wall and release the first outer tube assembly from the wall; control the drive device to extend, causing the first outer tube assembly to rise one stroke; alternately repeat the above attachment and drive actions until both the first and second outer tube assemblies have moved to the target installation position and are fixed to the wall, completing one climbing cycle.

[0015] The climbing mechanism and climbing process for a building construction machine provided by this invention consists of an outer sleeve assembly composed of an independent first sleeve assembly and a second sleeve assembly. This effectively shortens the overall axial length of the lifting column and reduces the size of individual components, thereby reducing the difficulty of manufacturing, transportation, and installation. Simultaneously, the first and second outer sleeve assemblies can alternately lock or unlock with the inner sleeve assembly, enabling the gradual lifting of the inner sleeve assembly and the gradual following of the outer sleeve assembly. This ensures that during the lifting process, the displacement range of the outer sleeve assembly relative to the inner sleeve assembly does not exceed one stroke of the drive device, thus limiting the displacement range of the outer sleeve assembly. This allows observers to clearly see all critical actions without changing their position throughout the process, completely eliminating safety hazards caused by interrupted vision and improving the safety and reliability of construction.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0019] See Figures 1 to 3 The image shows an example of a climbing mechanism for a building construction machine provided by the present invention.

[0020] The climbing mechanism for the building construction machine in this example mainly includes an inner tube assembly 1, a drive device 2, and an outer tube assembly.

[0021] The outer tube assembly includes a first outer tube assembly 3 and a second outer tube assembly 4 that are independent of each other and arranged sequentially along the axial direction of the inner tube assembly 1; the first outer tube assembly 3 and the second outer tube assembly 4 are slidably sleeved on the inner tube assembly 1; the driving device 2 is connected between the first outer tube assembly 3 and the second outer tube assembly 4 and can drive the first outer tube assembly 3 and the inner tube assembly 1 to move up and down relative to each other. The first outer tube assembly 3 and the second outer tube assembly 4 can be alternately locked or unlocked with the inner tube assembly 1, and gradually lift the inner tube assembly 1 under the drive of the drive device 2. During the lifting process, the displacement range of the outer tube assembly relative to the inner tube assembly 1 does not exceed one stroke of the drive device 2, thereby effectively shortening the overall axial length of the lifting column, reducing the size of a single piece, thereby reducing the difficulty of manufacturing, transportation and installation, limiting the displacement range of the outer tube assembly, and allowing the observer to clearly see all key actions without changing the standing position throughout the process, completely eliminating the safety hazards caused by the interruption of the line of sight, and improving the safety and reliability of construction.

[0022] After the inner tube assembly 1 is lifted into place, the drive device 2 can also drive the first outer tube assembly 3 and the second outer tube assembly 4 to move alternately along the inner tube assembly 1, so as to adjust the installation position of the outer tube assembly on the inner tube assembly 1 and follow the inner tube assembly 1 to climb.

[0023] Combination Figures 1 to 3 The outer tube assembly consists of a first outer tube assembly 3 and a second outer tube assembly 4, which are independent of each other. The first outer tube assembly 3 and the second outer tube assembly 4 are arranged sequentially along the axial direction of the inner tube assembly 1. The first outer tube assembly 3 is distributed above the second outer tube assembly 4, which effectively shortens the overall axial length of the lifting column and reduces the size of a single piece, thereby reducing the difficulty of manufacturing, transportation and installation.

[0024] Combination Figures 4 to 6 Furthermore, the first outer tube assembly 3 and the second outer tube assembly 4 have similar structures. Taking the first outer tube assembly 3 as an example, the first outer tube assembly 3 includes a first skeleton sleeve 31. The first skeleton sleeve 31 has an installation hole formed in the middle for cooperating with the inner tube assembly 1, and guide wheels 32 are respectively provided around the inner wall of the installation hole, so that the first skeleton sleeve 31 can be fitted onto the inner tube assembly 1 through the installation hole.

[0025] Furthermore, the inner tube assembly 1 is configured as a rectangular cross-section tube, so that the guide wheel 32 on the inner wall of the first skeleton sleeve 31 can roll into contact with the four outer edges of the rectangular cross-section tube, providing guidance and lateral restraint for the relative sliding of the first outer sleeve assembly 3 and the inner tube assembly 1.

[0026] The inner tube assembly 1 has several force-bearing holes 12 spaced apart on its side wall; combined with Figure 6 and Figure 7In conjunction with this, the first outer sleeve assembly 3 also includes a limiting plate 33, a handle 34, and a spring 35; the limiting plate 33 is hinged inside the first skeleton sleeve 31 by a pin 36, which extends out of the side plate of the first skeleton sleeve 31; the handle 34 and the spring 35 are arranged on the outside of the first skeleton sleeve 31, one end of the handle 34 is embedded in the groove of the pin 36, and the other end is connected to the spring 35; both ends of the spring 35 are respectively connected to the handle 34 and the top plate of the first skeleton sleeve 31, so that the handle 34 can drive the pin 36 and the limiting plate 33 to move.

[0027] In the initial state, the limiting plate 33 tends to engage with the force hole 12 under the spring force of the spring 35. Pulling down the handle 35 can overcome the spring force and drive the limiting plate 33 to rotate through the pin 36 to disengage from the force hole 12.

[0028] Combination Figure 4 and Figure 5 Furthermore, the first skeleton sleeve 31 is provided with a wall attachment node, which includes a bracket 6. The bracket 6 is hinged to the lower region of the first skeleton sleeve 31 by a pin, and can rotate on the first skeleton sleeve 31 without interfering with the guide wheel 32 and the limiting plate 33. The bracket 6 can rotate and extend out of the outside of the first skeleton sleeve 31 to extend into the mating hole 51 attached to the wall 5.

[0029] Combination Figure 8 Furthermore, the tail of the bracket 6 is equipped with a set screw 7, and the first skeleton sleeve 31 is equipped with a bracket limiting block 71 at the corresponding position of the tail of the bracket 6; so that when the bracket 6 rotates out of the first skeleton sleeve 31 and attaches to the mating hole 51 of the wall 5, the set screw 7 can press against the bracket limiting block 71 to limit the bracket 6 and prevent the bracket 6 from coming out, thus ensuring a stable fit between the bracket 6 and the wall 5. Figure 9 As shown.

[0030] The first outer tube assembly 3 thus formed can be fitted onto the inner tube assembly 1. The guide wheel 32 guides and limits the movement of the inner tube assembly 1, and the handle 34 controls the limit plate 33 to engage or disengage from the force-bearing hole 12 of the inner tube assembly 1, ensuring the stable locking or unlocking of the first outer tube assembly 3 and the inner tube assembly 1. At the same time, the first outer tube assembly 3 is stably engaged into the mating hole 51 of the wall 5 through the bracket 6, and is stably connected to the wall 5, ensuring the stable operation of the first outer tube assembly 3.

[0031] Combination Figures 10 to 12Correspondingly, the specific structure of the second outer sleeve assembly 4 is similar to that of the first outer sleeve assembly 3, including a second skeleton sleeve 41. The second skeleton sleeve 41 is also equipped with a guide wheel 32, a limiting plate 33, a handle 34, a spring 35, a bracket 6, and a set screw 7, so that the second outer sleeve assembly 4 can also be fitted onto the inner tube assembly 1 and distributed below the first outer sleeve assembly 3. The second outer sleeve assembly 4 also guides and limits the movement of the inner tube assembly 1 through the guide wheel 32, and controls the limiting plate 33 to engage or disengage from the force-receiving hole 12 of the inner tube assembly 1 through the handle 34, ensuring the stable locking or unlocking of the second outer sleeve assembly 4 and the inner tube assembly 1. At the same time, the second outer sleeve assembly 4 is stably engaged into the mating hole 51 of the wall 5 through the bracket 6, and stably connected to the wall 5, ensuring the stable operation of the second outer sleeve assembly 4.

[0032] Combination Figures 10 to 12 Furthermore, the wall attachment node of the second outer sleeve assembly 4 also includes anti-deviation screws 8 and top wall nut rods 9. The overall length of the second skeleton sleeve 41 is longer than that of the first skeleton sleeve 31, so that the anti-deviation screws 8 can be distributed at intervals in the lower area of ​​the second skeleton sleeve 41, and cooperate with the top wall nut rods 9 to connect to the wall 5, ensuring the stable operation of the second outer sleeve assembly 4.

[0033] Based on the above structure, the first outer tube assembly 3 and the second outer tube assembly 4 are independent of each other and are respectively fitted onto the inner tube assembly 1 to form the outer tube assembly. This can effectively shorten the overall axial length of the lifting column and reduce the size of individual parts, thereby reducing the difficulty of manufacturing, transportation and installation.

[0034] Combination Figures 13 to 14 In conjunction with this, the inner tube assembly 1 includes an inner tube body 11, and a plurality of force-bearing holes 12 are spaced apart on the side wall of the inner tube body 11, so that the inner tube body 11 can sequentially pass through the first outer tube assembly 3 and the second outer tube assembly 4, and the four outer edges can move axially along the guide wheels 32 of the first outer tube assembly 3 and the second outer tube assembly 4; and the limiting plates 33 on the first outer tube assembly 3 and the second outer tube assembly 4 can be engaged or disengaged from the force-bearing holes 12, locking or unlocking with the inner tube assembly 1.

[0035] Furthermore, the inner tube assembly 1 also includes a wall attachment node. The wall attachment node of the inner tube assembly 1 includes a bracket 6, a set screw 7, an anti-deviation screw 8, and a top wall nut rod 9. Preferably, the bracket 6 and the set screw 7 are disposed in the top area of ​​the inner tube body 11, and the anti-deviation screw 8 and the top wall nut rod 9 are distributed in the corresponding area of ​​the bracket 6 and below the bracket 6, so that the bracket 6 on the inner tube body 11 can be inserted into the mating hole 51 of the wall 5, and the anti-deviation screw 8 and the top wall nut rod 9 can be stably connected to the wall 5 to ensure the stable operation of the inner tube assembly 1.

[0036] Combination Figures 1 to 3To achieve the lifting of the inner tube assembly 1, the drive device 2 is connected between the first outer tube assembly 3 and the second outer tube assembly 4. It can drive the first outer tube assembly 3 and the inner tube assembly 1 to move up and down relative to each other. At the same time, the first outer tube assembly 3 and the second outer tube assembly 4 can alternately lock or unlock with the inner tube assembly 1. Under the drive of the drive device 2, the inner tube assembly 1 is gradually lifted. During the lifting process, the displacement range of the outer tube assembly relative to the inner tube assembly 1 does not exceed one stroke of the drive device 2, so as to limit the overall displacement range of the outer tube assembly. This allows the observer to clearly see all key actions without changing the standing position, completely eliminating the safety hazards caused by the interruption of the line of sight and improving the safety and reliability of the construction.

[0037] Preferably, the drive device 2 is composed of a hydraulic cylinder, which can drive the inner tube assembly 1 to rise relative to the outer tube assembly, or drive the outer tube assembly to move relative to the inner tube assembly 1, and can also drive the outer tube assembly to press against the inner tube assembly 1.

[0038] Combination Figure 15 As an example, during the lifting stage of the inner tube assembly 1, in the initial state, the first outer tube assembly 3, the second outer tube assembly 4, and the inner tube assembly 1 have all extended their brackets 6 and attached them to the mating holes 51 of the wall 5. The anti-deviation screws 8 and the top wall nut rods 9 of the second outer tube assembly 4 and the inner tube assembly 1 are all stably connected to the wall 5. At the same time, the limiting plates 33 of the first outer tube assembly 3 and the second outer tube assembly 4 are all pressed against the edge of the force-bearing hole 12 of the inner tube assembly 1.

[0039] Combination Figure 16 Before jacking, first release the wall attachment of the inner tube assembly 1 and release the lock between the second outer tube assembly 3 and the inner tube assembly 1 to prepare for jacking. Specifically, loosen the anti-deviation screw 8 and the top wall nut rod 9 of the inner tube assembly 1; drive the inner tube assembly 1 to rise a small distance to leave space for manual operation, manually move the handle 34 of the second outer tube assembly 4 to remove the limiting plate 33 in the second outer tube assembly 4 from the force hole 12, release the lock between the second outer tube assembly 3 and the inner tube assembly 1, and keep the first outer tube assembly 3 and the inner tube assembly 1 locked.

[0040] Combination Figure 17 Next, the first lifting begins. The drive device 2 lifts, causing the inner tube assembly 1 to rise one stroke. After the drive device 2 lifts one stroke (e.g., 600mm), the first outer tube assembly 3 and the inner tube assembly 1 are locked together. The drive device 2 will then drive the inner tube assembly 1 and the first outer tube assembly 3 to rise one stroke simultaneously, and also drive the truss platform connected to the inner tube assembly 1 to climb one stroke simultaneously.

[0041] Combination Figure 18Further, the second outer tube assembly 4 is reset, locking it to the inner tube assembly 1, while the first outer tube assembly 3 is unlocked from the inner tube assembly 1. The control drive device 2 retracts, causing the first outer tube assembly 4 to descend and reset. The handle 34 of the second outer tube assembly 4 is manually moved to re-clamp the limiting plate 33 of the second outer tube assembly 4 into the next set of force holes 12 of the inner tube assembly 1, locking the second outer tube assembly 3 to the inner tube assembly 1. Simultaneously, the handle 34 of the first outer tube assembly 3 is manually moved to remove the limiting plate 33 of the first outer tube assembly 3 from the force holes 12 of the inner tube assembly 1, releasing the lock between the first outer tube assembly 3 and the inner tube assembly 1, while maintaining the lock between the second outer tube assembly 3 and the inner tube assembly 1. At this point, the drive device 2 retracts one stroke, causing the first outer tube assembly 4 to descend one stroke synchronously, thus resetting the first outer tube assembly 4.

[0042] At that time, preparations will be made for the second lifting, the locking of the second outer tube assembly 3 and the inner tube assembly 1 will be released, and the locking of the first outer tube assembly 3 and the inner tube assembly 1 will be maintained.

[0043] Similar to the first jacking, a second jacking is performed. Drive device 2 jacks up, causing the inner tube assembly 1 to rise one stroke. Drive device 2 jacks up one stroke (e.g., 600mm). At this time, the first outer tube assembly 3 and the inner tube assembly 1 are locked. Drive device 2 will then cause the inner tube assembly 1 and the first outer tube assembly 3 to rise synchronously again one stroke, and cause the truss platform connected to the inner tube assembly 1 to climb synchronously again one stroke. The truss platform climbs a total of two strokes (e.g., 1200mm).

[0044] Similarly, the second outer tube assembly 4 is reset again, locking the second outer tube assembly 4 and the inner tube assembly 1, while the first outer tube assembly 3 and the inner tube assembly 1 are unlocked. The control drive device 2 is then retracted, causing the first outer tube assembly 4 to descend and reset.

[0045] By alternating the locking states of the first outer tube assembly 3 and the second outer tube assembly 4 with the inner tube assembly 1, the lifting and resetting steps are repeated until the inner tube assembly 1 reaches the target height. The bracket 6, anti-deviation screw 8 and top wall nut rod 9 of the inner tube assembly 1 are then reattached and fixed to the wall 5 to complete the lifting of the inner tube assembly 1.

[0046] During the lifting process, based on the alternating locking and resetting of the first outer tube assembly 3 and the second outer tube assembly 4 with the inner tube assembly, the displacement range of the outer tube assembly relative to the inner tube assembly 1 does not exceed one stroke of the drive device 2 (not exceeding 600mm); all key moving components are within the fixed field of view that the observer can see directly, so that the observer can clearly see all key movements without changing the position throughout the process, without having to follow the movement of the column until the lifting is safely in place.

[0047] In order to enable the outer tube assembly to follow the inner tube assembly 1 in climbing and to enable the inner tube assembly 1 to continue to be lifted, the drive device 2 can also drive the first outer tube assembly 3 and the second outer tube assembly 4 to move alternately along the inner tube assembly 1 after the inner tube assembly 1 is lifted into place, so as to adjust the installation position of the outer tube assembly on the inner tube assembly 2 and follow the inner tube assembly 1 in climbing.

[0048] Combination Figures 1 to 3 As an example, during the outer sleeve installation phase, the first outer sleeve assembly 3 is first attached to the wall 5, and the second outer sleeve assembly 4 is then removed from the wall. The bracket 6 of the first outer sleeve assembly 3 is extended and attached to the mating hole 51 in the wall 5. Then, the bracket 6, anti-deviation screw 8, and top wall nut rod 9 of the second outer sleeve assembly 4 are loosened. At this time, the control drive device 2 retracts, causing the second outer sleeve assembly 4 to rise one stroke (e.g., 600mm).

[0049] Further, the second outer sleeve assembly 4 is attached to the wall 5, the first outer sleeve assembly 3 is released from the wall, and then the drive device 2 is extended to drive the first outer sleeve assembly 3 to rise by one stroke (e.g., 600mm).

[0050] The above attachment and driving actions are repeated alternately until both the first outer sleeve assembly 3 and the second outer sleeve assembly 4 have moved to the target installation position and are fixed to the wall 5, completing one climbing cycle.

[0051] Correspondingly, during the outer tube follow-up process, the displacement range of the outer tube assembly relative to the inner tube assembly 1 does not exceed one stroke of the drive device 2 (not exceeding 600mm). All key moving components are within the fixed field of view that the observer can see directly, so that the observer can clearly see all key movements without changing the position throughout the process, without having to follow the movement of the column until the jacking is safely in place.

[0052] Therefore, the displacement range of the outer sleeve assembly is limited, allowing the observer to clearly see all key actions without changing their position throughout the process, completely eliminating the safety hazards caused by interrupted vision and improving the safety and reliability of construction.

[0053] Here, the drive control of drive device 2 can be controlled by a field PLC control cabinet or a remote controller.

[0054] This constitutes the climbing mechanism for building construction machines provided by the present invention.

[0055] The present invention also provides a climbing process for a building construction machine, based on a climbing mechanism for a building construction machine constructed using the above-described scheme, the climbing process comprising: Inner tube lifting stage: Release the wall attachment of inner tube assembly 1 and release the lock between the second outer tube assembly 4 and inner tube assembly 1; control the drive device 2 to lift, driving the inner tube assembly 1 to rise one stroke; lock the second outer tube assembly 4 and inner tube assembly 1, and unlock the first outer tube assembly 3 and inner tube assembly 1; control the drive device 2 to retract, driving the first outer tube assembly 3 to descend and reset; alternately switch the locking states of the first outer tube assembly 3 and second outer tube assembly 4 with the inner tube assembly 1, repeating the lifting and resetting steps until the inner tube assembly 1 reaches the target height, and reattach and fix the inner tube assembly 1 to the wall 5, and the displacement range of the outer tube assembly relative to the inner tube assembly 1 does not exceed one stroke of the drive device.

[0056] Outer tube follow-up stage: Attach the first outer tube assembly 3 to the wall 5 and release the second outer tube assembly 4 from the wall; control the drive device 2 to retract, driving the second outer tube assembly 4 to rise one stroke; attach the second outer tube assembly 4 to the wall 5 and release the first outer tube assembly 1 from the wall; control the drive device 2 to extend, driving the first outer tube assembly 3 to rise one stroke; alternately repeat the above attachment and drive actions until both the first outer tube assembly 3 and the second outer tube assembly 4 have moved to the target installation position and are fixed to the wall, completing one climbing cycle.

[0057] The climbing mechanism and climbing process for a building construction machine provided by this invention consists of an outer sleeve assembly composed of an independent first sleeve assembly and a second sleeve assembly. This effectively shortens the overall axial length of the lifting column and reduces the size of individual components, thereby reducing the difficulty of manufacturing, transportation, and installation. Simultaneously, the first and second outer sleeve assemblies can alternately lock or unlock with the inner sleeve assembly, enabling the gradual lifting of the inner sleeve assembly and the gradual following of the outer sleeve assembly. This ensures that during the lifting process, the displacement range of the outer sleeve assembly relative to the inner sleeve assembly does not exceed one stroke of the drive device, thus limiting the displacement range of the outer sleeve assembly. This allows observers to clearly see all critical actions without changing their position throughout the process, completely eliminating safety hazards caused by interrupted vision and improving the safety and reliability of construction.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
