Existing building cranes typically rely on the lifting mechanisms of multiple external supports to provide lifting power. On the one hand, the entire building crane is completely supported by these external supports, which subject the walls where the external supports are located to significant shear forces. Furthermore, when these external supports experience localized stress concentration and severe wear due to variations in machining precision or long-term high-load operation, this further increases the shear forces on the walls, impacting the overall stability of the building crane. On the other hand, the smooth operation of the building crane depends on the consistency of the power drives of each lifting station. When there are differences in the power drive rhythm of each lifting station, the stability of the building crane during the climbing process is affected. Summary of the Invention

DETAILED DESCRIPTION

[0016] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0017] like Figure 1 、 Figure 2As shown, the present invention discloses an embodiment of a light cantilever beam type lifting external cross-section protection building construction machine, comprising a central column 1, a cantilever beam 2, an external protection hanger 3, a balanced traction mechanism and a lifting mechanism 5, wherein the external protection hanger 3 is distributed on the periphery of the central column 1, and one end of the cantilever beam 2 is connected to the external protection hanger 3, and the other end is connected to the central column 1, and the lifting mechanism 5 is connected to the central column 1 and the construction body A, and is used to drive the central column 1 to rise and fall; the balanced traction mechanism is set as a multi- group, each group of the balanced traction mechanism includes a traction member 41, a fixed guide wheel 42 and a dynamic guide wheel 43, at least the fixed guide wheel 42 is provided on the cantilever beam 2, and the dynamic guide wheel 43 is provided on the outer protective hanger 3, one end of the traction member 41 is connected to the construction body A, and the other end passes around the dynamic guide wheel 43 and the fixed guide wheel 42 in turn, and is connected to the driving end of the central column 1 or the lifting mechanism 5, wherein the dynamic guide wheel 43 is located below the connection position between the traction member 41 and the construction body A.

[0018] In this embodiment, the outer protection hanger 3 is distributed on the outer periphery of the central column 1, so that one end of the cantilever beam 2 is connected to the outer protection hanger 3 and the other end is connected to the central column 1. The lifting mechanism 5 drives the central column 1 to rise and fall, so that the cantilever beam 2 and the outer protection hanger 3 of the entire building construction machine can be raised and lowered at the same speed. The climbing of the building construction machine is driven by a single power, which simplifies the power control and avoids the problem of unstable operation caused by the difference in the beat control of multiple power drives; at the same time, the dynamic guide wheel 43 of the balancing traction mechanism is set on the outer protection hanger 3, and the fixed guide wheel 42 is at least set on the cantilever beam 2, one end of the traction member 41 is connected to the construction body A above the dynamic guide wheel 43, and the other end passes around the dynamic guide wheel 43 and The fixed guide wheel 42 is connected to the driving end of the central column 1 or the lifting mechanism 5. Although the external protection hangers 3 in various places may have different loads, the loads in various places are concentrated on the central column 1 through the traction parts 41 and then dispersed to the construction subjects A in various directions through other traction parts 41, thereby improving the balance of the overall structure and ensuring that the cantilever beams 2 and external protection hangers 3 in various directions can maintain a consistent lifting speed. At the same time, the weight of the building construction machine is evenly dispersed to the construction subjects A in various directions through the dynamic guide wheels 43 on each external protection hanger 3, and also shares the force on the wall connecting the construction subject A and the lifting mechanism 5, reducing the wall bearing capacity requirements for the construction subject A, and more conducive to improving the overall stability of the building construction machine.

[0019] For ease of explanation, the location where the construction body A connects to the lifting mechanism 5 in this embodiment is referred to as the first load-bearing location, and the location where the construction body A connects to the traction member 41 is referred to as the second load-bearing location. Obviously, the second load-bearing locations are distributed around the first load-bearing location. To help improve the overall stability of the building construction machine, the second load-bearing locations can be arranged in a circumferential array around the first load-bearing locations, and the weight of the entire building construction machine can be kept as relatively balanced as possible in all directions. The cantilever beam 2 and external protective hanger 3 of this embodiment are preferably made of lightweight materials, such as aluminum alloy components.

[0020] Specifically, the first load-bearing position of this embodiment is a shaft located in the center of the construction body A. A guide rail (not shown in the figure) is provided in the shaft and slides with the central column 1. The central column 1 is slidably arranged in the shaft, and the lifting mechanism 5 is connected to the wall of the shaft, that is, the concrete of the wall of the shaft provides bearing capacity for it.

[0021] The lifting mechanism 5 has an anti-fall function and is preferably provided with a first lifting cylinder and a second lifting cylinder, which are two sets of alternating lifting hydraulic cylinders connected to the central column 1. The dual hydraulic cylinders alternately lift to achieve a continuous lifting system design, which facilitates reversing operations.

[0022] The construction body A specifically includes a constructed layer A1 and a working layer A0 to be constructed. The constructed layer A1 is located below the working layer A0 to be constructed. The constructed layer A1 is the portion of the construction body A that has been constructed and hardened. The construction equipment installed on the cantilever beam 2 is located on the working layer A0 to be constructed. The hoistway, or the first load-bearing position, is located in the center of the constructed layer A1. The end of the constructed layer A1 away from the central column 1 is the second load-bearing position, which is provided with a suspension support 6. The traction member 41 is connected to the suspension support 6 of the constructed layer A1.

[0023] Since the relative position between the dynamic guide wheel 43 and the fixed guide wheels 42 remains unchanged during the lifting process of the building construction machine, the central column meets the stiffness required for the positive pressure of all moving part loads, the cantilever beam meets the stiffness required for the positive pressure generated by the pulling force of the traction member in the corresponding direction it bears, and the horizontal truss beam on the external protective hanger meets the stiffness required for the positive pressure generated by the pulling force of the traction member in the corresponding direction it bears. When the traction length of the traction member 41 remains unchanged and tensioned, the seismic resistance of the cantilever beam 2, the external protective hanger 3 and the central column 1 is improved, and the lifting speed of the cantilever beam 2 and the external protective hanger 3 is consistent with the lifting speed of the central column 1 given by the power.

[0024] As the number of constructed layers A1 increases, the central column 1 is also continuously lifted. By changing the connection position of the traction member 41 and the second load-bearing position, the connection position of the traction member 41 and the second load-bearing position is always maintained above the movable guide wheel 43 of the outer protective hanger 3.

[0025] In this embodiment, one end of the traction member 41 is preferably connected to the second load-bearing position of the construction body A through a suspension support 6, and the other end is passed around the movable guide wheel 43 and the fixed guide wheel 42 in sequence, and is connected to the driving end of the lifting mechanism 5 to provide an upward pulling effect on the lifting mechanism 5, thereby reducing the bearing requirements for concrete at this location.

[0026] Preferably, in this embodiment, a first fixed guide wheel 42a is provided at the top of the central column 1, and a second fixed guide wheel 42b is provided on the cantilever beam 2. The balancing and pulling mechanisms of this embodiment are provided corresponding to the cantilever beam 2 and the outer protective hanger 3. Multiple sets of balancing and pulling mechanisms can be provided corresponding to the outer protective hangers 3 in each direction as needed. The central column 1 of this embodiment can be configured as a tubular structure, or its cross-section can be configured as an I-beam to facilitate the layout of the pulling member 41.

[0027] Taking the central column 1 of an I-shaped or frame-shaped cross-section as an example, in order to ensure torque balance on the central column 1, a first array and a second array of first fixed guide wheels 42a are set on the top of the central column 1. The first array and the second array are parallel to the first outer protective hanger 3 and the second outer protective hanger 3 on opposite sides of the central column 1, wherein the first array is set close to the second protective hanger, and the second array is set close to the first protective hanger. A first traction member 41a is wound around each first guide wheel of the first array, and the first protective hanger is connected to the first traction member 41a. A second traction member 41b is wound around each second guide wheel of the second array, and the second protective hanger is connected to the second traction member 41b. The traction members 41 of each set of balanced traction mechanisms are preferably staggered and set on different planes to avoid interference between the traction members 41 and fixed guide wheels 42 of each set of balanced traction mechanisms.

[0028] To accommodate construction at varying heights and the increasing number of constructed floors A1, this embodiment preferably includes a wire clamp (not shown) on the traction member 41. This clamp is used to adjust the traction length of the traction member 41. The traction member 41 can be a wire rope, a traction chain, or the like. When the traction member 41 is a wire rope, the movable guide wheel 43 is a movable pulley, and the fixed guide wheel 42 is a fixed pulley. When the traction member 41 is a traction chain, both the movable guide wheel 43 and the fixed guide wheel 42 are circumferentially provided with serrations compatible with the traction chain. The wire clamp allows the traction member 41 to be folded or reeled to adjust its traction length.

[0029] Since the wire clamp moves with the entire building construction machine, in order to facilitate operation and maintenance, this embodiment preferably sets the wire clamp at at least one between the first fixed guide wheel 42a and the second fixed guide wheel 42b, or between the second fixed guide wheel 42b and the movable guide wheel 43.

[0030] The cantilever beam 2 of this embodiment includes a fixed section 21 and a telescopic section 22. The fixed section 21 is connected to the central column 1. One end of the telescopic section 22 is connected to the outer protective hanger 3, and the other end is slidably connected to the fixed section 21. The telescopic section 22 slides relative to the fixed section 21 toward or away from the central column 1 to adjust the length of the cantilever beam 2, thereby adjusting the distance between the outer protective hanger 3 and the shaft to adapt to the construction of floors with different external cross-sections.

[0031] When the lifting mechanism 5 stops working, the external protection hanger 3 can be adjusted to accommodate changes in the external cross-section of the construction unit. Correspondingly, the length of the traction member 41 in the balanced traction mechanism must be adjusted. Specifically, the traction member 41 is retracted and extended using a wire clamp, causing it to exert a pulling effect on the external protection hanger 3, the cantilever beam 2, and the central column 1. The external protection hanger 3, the central column 1, and the cantilever beam 2 rise and fall together, unloading the load from the inner wall of the shaft of the construction unit A (i.e., the first load-bearing position) to the outer wall of the construction unit A (i.e., the second load-bearing position). This allows for rapid adaptation to the construction of floors of varying cross-sections while ensuring the overall smooth operation of the building machine. To facilitate the adjustment of the cantilever beam 2, this embodiment preferably sets the second fixed guide wheel 42b on the telescopic section 22 of the cantilever beam 2, so that the second fixed guide wheel 42b can move and adjust the position together with the telescopic section 22 and the outer protective hanger 3, ensuring that the second fixed guide wheel 42b is set directly above the moving guide wheel 43.

[0032] The lifting mechanism of this embodiment is connected to the concrete in the shaft of the construction unit via the lifting support. With this mechanism, the load on the lifting support is reduced by the balanced traction mechanism pulling the outer protective hanger upward. The pressure on the lifting support can be reduced to only about one-third of the total weight of the moving part, which greatly improves and reduces the load-bearing requirements of the concrete at the lifting support.

[0033] The present invention provides a central column driven by a lifting mechanism in the shaft, external protective hangers distributed on the periphery of the central column, a cantilever beam connecting the external protective hanger and the central column, and a balancing traction mechanism. The light cantilever beam-type lifting external cross-section protection building construction machine of the present invention is subjected to less force than the building construction machine in the prior art through the four-lifting machine position-four-column power system, thereby reducing the concrete tension on the construction body and improving safety and reliability.

[0034] The above disclosure is only a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
