Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a variable cross-section protective building construction machine. Background Technology

[0002] Existing building construction machines are generally supported by external anchor points on the building, with each anchor point serving as a lifting position. This results in existing building construction machines typically relying on various lifting mechanisms at multiple anchor points to provide the power for lifting and lowering. On the one hand, the stable operation of the building construction machine depends on the consistency of the power drive at each lifting position. When there are differences in the power drive cycle of the lifting positions, it will affect the stability of the building construction machine during the climbing process. On the other hand, building construction machines with this structure are difficult to adapt to construction structures with different external cross-sections. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a variable cross-section protective building machine that can adapt to construction bodies with different external cross-sections and help improve the climbing stability of the building machine.

[0004] To solve the above-mentioned technical problems, this utility model provides a variable cross-section protective building construction machine, including a central column, a cantilever beam, an outer protective hanger, and a lifting mechanism. The lifting mechanism is connected to the central column and the main construction body and is used to drive the central column to rise and fall. The main construction body is provided with a shaft, the central column is slidably installed in the shaft, and the lifting mechanism is connected to the shaft wall.

[0005] The outer protective hangers are distributed around the outer perimeter of the central column. The cantilever beam includes a fixed section and a telescopic section. The fixed section is connected to the central column. One end of the telescopic section is connected to the outer protective hangers, and the other end is slidably connected to the fixed section. The telescopic section can slide relative to the fixed section towards or away from the central column.

[0006] As an improvement to the above solution, multiple sets of balancing traction mechanisms are also included. Each set of balancing traction mechanisms includes a traction component, a fixed guide wheel, and a moving guide wheel. At least the fixed guide wheel is provided on the cantilever beam, and the moving guide wheel is provided on the outer protective hanger. One end of the traction component is connected to the construction body, and the other end passes around the moving guide wheel and the fixed guide wheel in sequence, and is connected to the drive end of the central column or the lifting mechanism. The moving guide wheel is located below the connection position between the traction component and the construction body.

[0007] As an improvement to the above scheme, the top of the central column is provided with a first fixed guide wheel, and the cantilever beam is provided with a second fixed guide wheel.

[0008] As an improvement to the above solution, the traction member is provided with a wire clamp, which is used to adjust the traction length of the traction member.

[0009] As an improvement to the above solution, the wire clamp is provided between the first fixed guide wheel and the second fixed guide wheel, and / or between the second fixed guide wheel and the moving guide wheel.

[0010] As an improvement to the above solution, the cantilever beam includes a fixed section and a telescopic section. The fixed section is connected to the central column, one end of the telescopic section is connected to the outer protective hanger, and the other end is slidably connected to the fixed section. The telescopic section slides relative to the fixed section in a direction closer to or farther from the central column to adjust the length of the cantilever beam.

[0011] As an improvement to the above scheme, the second fixed guide wheel is disposed in the telescopic section of the cantilever beam, and the second fixed guide wheel is disposed directly above the moving guide wheel.

[0012] As an improvement to the above scheme, the first fixed guide wheel at the top of the central column is set as a first array and a second array arranged in parallel.

The second traction member passes through two adjacent first fixed guide wheels of the first array and goes around the first fixed guide wheel of the second array.

[0013] As an improvement to the above scheme, the construction body includes a constructed layer and a construction work layer. The constructed layer is located below the construction work layer. A suspension support is provided at one end of the constructed layer away from the central column. The traction member is connected to the suspension support of the constructed layer.

[0014] As an improvement to the above solution, the central column is a tubular structure, or the cross-section of the central column is I-shaped, and the top surface of the central column is provided with an assembly surface for mounting the guide wheel.

[0016] Implementing this utility model has the following beneficial effects:

[0017] This utility model discloses a variable cross-section protective building construction machine. By distributing the outer protective hangers around the outer perimeter of the central column, one end of the cantilever beam is connected to the outer protective hangers, and the other end is connected to the central column. The lifting mechanism drives the central column to rise and fall, so that the cantilever beam and outer protective hangers of the entire building construction machine rise and fall at the same speed. The climbing of the building construction machine is driven by a single power source, simplifying power control. Although the loads of the outer protective hangers at different locations are different, they all move at the same speed, avoiding the problem of unstable operation caused by the difference in the control of multiple power drives. At the same time, by setting the central column in the shaft of the construction body and driving it with a single power source, the drive structure is simpler. The cantilever beam can be designed as a telescopic structure including a fixed section and a telescopic section to adjust the distance between the outer protective hangers and the shaft, adapting to the construction of floors with different outer cross-sections, thus having wider adaptability.

[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 2 As shown, this utility model discloses an embodiment of a variable cross-section protective building construction machine, including a central column 1, a cantilever beam 2, an outer protective hanger 3, a balancing traction mechanism, and a lifting mechanism 5. The outer protective hanger 3 is distributed around the outer periphery of the central column 1, and one end of the cantilever beam 2 is connected to the outer protective hanger 3, while the other end is connected to the central column 1. 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. In this embodiment, the cantilever beam 2 includes a fixed section 21 and a telescopic section 22. The fixed section 21 is connected to the central column 1, and one end of the telescopic section 22 is connected to the outer protective hanger 3, while the other end is slidably connected to the fixed section 21. The telescopic section 22 slides relative to the fixed section 21 towards 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, adapting to the construction of floors with different outer cross-sections.

[0022] In this embodiment, the outer protective hangers 3 are distributed around the outer perimeter of the central column 1, so that one end of the cantilever beam 2 is connected to the outer protective hangers 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 protective hangers 3 of the entire building machine rise and fall together at the same speed. The climbing of the building 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 cycle control of multiple power drives. At the same time, by setting the central column in the shaft of the construction body and driving it with a single power, the drive structure is simpler. The cantilever beam can be designed as a telescopic structure including a fixed section and a telescopic section to adjust the distance between the outer protective hangers and the shaft, adapting to the construction of floors with different outer cross sections, thus having wider adaptability.

[0023] In addition, the variable cross-section protective building machine of this embodiment is also equipped with multiple sets of balancing traction mechanisms. Each set of balancing traction mechanisms includes a traction component 41, a fixed guide wheel 42, and a moving guide wheel 43. At least the fixed guide wheel 42 is provided on the cantilever beam 2, and the moving guide wheel 43 is provided on the outer protective hanger 3. One end of the traction component 41 is connected to the construction body A, and the other end passes around the moving guide wheel 43 and the fixed guide wheel 42 in sequence, and is connected to the drive end of the central column 1 or the lifting mechanism 5. The moving guide wheel 43 is located below the connection position between the traction component 41 and the construction body A. Meanwhile, the moving guide wheel 43 of the balancing traction mechanism is set on the outer protective hanger 3, and the fixed guide wheel 42 is set on the cantilever beam 2 at least. One end of the traction component 41 is connected to the construction body A above the moving guide wheel 43, and the other end passes around the moving guide wheel 43 and the fixed guide wheel 42 in sequence, and is connected to the drive end of the central column 1 or the lifting mechanism 5. Although the loads of the outer protective hangers 3 may vary in different places, the loads distributed in different places are concentrated in the central column 1 through the traction component 41 and then distributed to the construction body A in each direction through other traction components 41, which improves the balance of the overall structure and ensures that the cantilever beam 2 and the outer protective hanger 3 in each direction can maintain a consistent lifting speed. At the same time, the weight of the building machine is evenly distributed to the construction body A in each direction through the moving guide wheel 43 on each outer protective hanger 3, which also shares the force on the wall connecting the construction body A and the lifting mechanism 5, reduces the load-bearing capacity requirement of the wall of the construction body A, and helps to improve the overall stability of the building machine.

[0024] For ease of explanation, in this embodiment, the position where the main construction body A connects to the lifting mechanism 5 is referred to as the first load-bearing position, and the position where the main construction body A connects to the traction component 41 is referred to as the second load-bearing position. Clearly, the second load-bearing positions are distributed around the first load-bearing position. To help improve the overall stability of the building machine, the second load-bearing positions can be arranged in a circumferential array along the first load-bearing position, ensuring that the weight of the building machine is kept as relatively balanced as possible in all directions. In this embodiment, the cantilever beam 2 and the external protective hanger 3 are preferably made of lightweight materials, such as aluminum alloy components.

[0025] Specifically, in this embodiment, the first load-bearing position is the shaft located in the center of the construction body A. A guide rail (not shown in the figure) is installed in the shaft and slides with the central column 1. The central column 1 is slidably installed in the shaft, and the lifting mechanism 5 is connected to the shaft wall, that is, the concrete of the shaft wall provides the bearing capacity.

[0026] The lifting mechanism 5 has an anti-fall function and preferably includes 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 system design of alternating lifting by dual hydraulic cylinders to achieve continuous lifting facilitates reversing operations.

[0027] The main construction unit A specifically includes a constructed layer A1 and a work layer A0 to be constructed. The constructed layer A1 is located below the work layer A0. The constructed layer A1 is the completed and hardened part of the main construction unit A, and the construction equipment installed on the cantilever beam 2 is located in the work layer A0. The shaft, i.e., 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, where a suspension support 6 is provided. The traction member 41 is connected to the suspension support 6 of the constructed layer A1.

[0028] Since the relative positions between the moving guide wheel 43 and each fixed guide wheel 42 remain unchanged during the lifting and lowering process of the building machine, the central column has the necessary stiffness to meet the normal pressure of the load of all moving parts, the cantilever beam has the necessary stiffness to meet the normal pressure generated by the tension of the traction component in the corresponding direction, and the horizontal truss beam on the outer protective hanger has the necessary stiffness to meet the normal pressure generated by the tension of the traction component in the corresponding direction. With the traction length of the traction component 41 remaining unchanged and tensioned, the seismic performance of the cantilever beam 2, the outer protective hanger 3 and the central column 1 are improved, and the lifting speed of the cantilever beam 2 and the outer protective hanger 3 is consistent with the lifting speed of the central column 1 powered by the power.

[0029] As the number of constructed layers A1 increases, the central column 1 is also continuously lifted. By changing the connection position between the traction component 41 and the second load-bearing position, the connection position between the traction component 41 and the second load-bearing position is always kept above the moving guide wheel 43 of the outer protective hanger 3.

[0030] 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 the suspension support 6, and the other end passes around the moving guide wheel 43 and the fixed guide wheel 42 in sequence, and is connected to the drive end of the lifting mechanism 5, so as to provide an upward pulling force to the lifting mechanism 5 and reduce the load-bearing requirements of the concrete at this point.

[0031] Preferably, in this embodiment, a first guide wheel 42a is provided at the top of the central column 1, and a second guide wheel 42b is provided on the cantilever beam 2. The balancing traction mechanism in this embodiment is correspondingly arranged with the cantilever beam 2 and the outer protective hanger 3. As needed, multiple sets of balancing traction mechanisms can be correspondingly arranged on the outer protective hanger 3 in each direction. The central column 1 in this embodiment can be configured as a tubular structure, or its cross-section can be I-shaped to facilitate the layout of the traction component 41.

[0032] Taking a central column 1 with an I-shaped or frame-shaped cross-section as an example, to ensure torque balance in the central column 1, a first array and a second array of first fixed guide wheels 42a are provided on the top of the central column 1. The first array and the second array are parallel to and opposite to the first and second outer protective hangers 3 on opposite sides of the central column 1. The first array is positioned closer to the second protective hanger, and the second array is positioned closer to the first protective hanger. Each first guide wheel of the first array is wound with a first traction member 41a, and the first protective hanger is connected to the first traction member 41a. Each second guide wheel of the second array is wound with a second traction member 41b, and the second protective hanger is connected to the second traction member 41b. The traction members 41 of each group of balancing traction mechanisms are preferably staggered and arranged on different planes to avoid interference between the traction members 41 and fixed guide wheels 42 of each group of balancing traction mechanisms.

[0033] To accommodate construction at varying floor heights and address the increasing number of completed floors (A1), this embodiment preferably includes a clamp (not shown in the figure) on the traction member 41. The 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, etc. When the traction member 41 is a wire rope, the moving 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 moving guide wheel 43 and the fixed guide wheel 42 have serrations in the circumferential direction that are compatible with the traction chain. The clamp can fold and fix the traction member 41, or coil it up to change its traction length.

[0034] 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 least between the first fixed guide wheel 42a and the second fixed guide wheel 42b, and between the second fixed guide wheel 42b and the moving guide wheel 43.

[0035] When the lifting mechanism 5 stops working, the external protective hanger 3 can be adjusted to adapt to changes in the outer cross-section of the main construction structure. Correspondingly, the length of the traction component 41 in the balancing traction mechanism needs to be adjusted. Specifically, the traction component 41 is extended and retracted through the clamp, so that the traction component 41 forms a traction effect on the external protective hanger 3, the cantilever beam 2 and the central column 1. The external protective hanger 3, the central column 1 and the cantilever beam 2 are raised and lowered as a whole, and the load on the inner wall of the shaft of the main construction structure A (i.e., the first load-bearing position) is unloaded onto the outer wall of the main construction structure A (i.e., the second load-bearing position). This allows for rapid adaptation to the construction of floors with different cross-sectional sizes while helping the building machine to operate smoothly as a whole.

[0036] To facilitate the adjustment of the cantilever beam 2, in this embodiment, the second fixed guide wheel 42b is preferably set in the telescopic section 22 of the cantilever beam 2, so that the second fixed guide wheel 42b can move and adjust its position together with the telescopic section 22 and the outer protective hanger 3, ensuring that the second fixed guide wheel 42b is positioned directly above the moving guide wheel 43.

[0037] In this embodiment, the lifting mechanism is connected to the concrete inside the shaft of the main construction body via a lifting support. Using this new mechanism, the load on the lifting support is reduced because the balancing traction mechanism pulls the outer protective hanger upwards. The pressure on the lifting support can be reduced to approximately one-third of the weight of the entire moving part, which greatly improves and lowers the load-bearing requirements of the concrete at the lifting support.

[0038] This invention, by setting up a central column driven by a hoisting mechanism inside the shaft, outer protective hangers distributed around the central column, and a cantilever beam connecting the outer protective hangers and the central column, along with a balancing traction mechanism, makes the building machine of this invention experience less force through the four-lifting-four-column power system compared to existing building machines. This reduces the tensile force on the concrete of the main construction structure and improves safety and reliability.

[0039] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
