[0017] The following are specific embodiments of the present application, which, in conjunction with the accompanying drawings, further describe the technical solutions of the present application. However, the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to facilitate a comprehensive understanding of the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, for the sake of clarity and brevity, descriptions of known functions and structures have been omitted.

[0018] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0019] like Figure 1 and Figure 2 The specific embodiment of the building construction machine jacking system shown includes: an upper standard section 1, a new standard section 5, a support drum frame 9, a movable leg-type jacking cylinder 14, a large jacking cylinder 18 and a lower standard section 24; the lower portion of the upper standard section 1 is connected to the upper portion of the support drum frame 9 by a connector 29, the lower standard section 24 is supported on the upper portion of the large jacking cylinder 18, the support drum frame 9 is sleeved on the outer periphery of the lower standard section 24, and its cross section is C-shaped with an open side; the movable leg-type jacking cylinder 14 is in four groups and evenly distributed within the lower standard section 24; the top of the movable leg-type jacking cylinder 14 is connected to the middle support 13 of the support drum frame; When the movable leg-type jacking cylinder 14 and the large jacking cylinder 18 are jointly jacked to a certain distance, the newly inserted standard section 5 can enter the middle support 13 of the support cylinder frame through the opening side; The upper part of the newly inserted standard section 5 is connected to the lower part of the upper standard section 1 through a second connecting piece 30, and the lower part of the newly inserted standard section 5 is supported on the middle support 13 of the support cylinder frame; the upper part of the large jacking cylinder 18 supports the lower part of the support cylinder frame 9, the lower part of the lower standard section 24 and the lower part of the movable leg-type jacking cylinder 14.

[0020] Specifically, during the jacking operation, four groups of movable leg-type jacking cylinders 14 work together with the large jacking cylinder 18 to form a composite support system. The C-shaped structure of the support drum frame 9 forms an open channel during the jacking process, and the newly inserted standard section 5 slides laterally to the predetermined position through the open side. There are four groups of movable leg-type jacking cylinders 14, which are evenly distributed in the lower standard section 24, so that the jacking force is evenly transmitted to the middle support 13 of the support drum frame, effectively controlling the horizontal offset. When the newly inserted standard section 5 is docked with the upper standard section 1, the second connector 30 realizes a reliable connection between the two standard sections, forming a continuous load-bearing structure.

[0021] Through the above technical solution, the present application effectively eliminates horizontal offset and slippage during the jacking process. The evenly distributed layout of the four sets of movable leg-type jacking cylinders 14 ensures jacking synchronization. The C-shaped structural design of the support cylinder frame 9 enables horizontal assembly of standard sections, avoiding traditional wall drilling operations. The composite jacking system forms a closed-loop force system, improving structural stability. Standardized connectors enable rapid disassembly and assembly, shortening the jacking operation cycle. The coordinated work of the cylinder and the support structure ensures a safe and controllable construction process.

[0022] In other preferred embodiments, Figure 3-6 As shown, the upper standard section 1 includes the upper standard section vertical rod 2, the upper standard section horizontal rod 3 and the upper standard section diagonal web rod 4; the new standard section 5 includes the new standard section vertical rod 6, the new standard section horizontal rod 7 and the new standard section diagonal web rod 8; the support tube frame 9 includes the support tube frame vertical rod 10, the support tube frame horizontal rod 11 and the support tube frame diagonal web rod 12; the lower standard section 24 includes the lower standard section vertical rod 25, the lower standard section horizontal rod 26 and the lower standard section diagonal web rod 27.

[0023] Specifically, vertical rods, cross rods, and diagonal webs are welded or bolted together to form a spatial truss structure. The vertical rods serve as the primary load-bearing components and are arranged vertically. Cross rods connect multiple vertical rods in the horizontal plane to form a rigid frame. Diagonal webs cross the vertical rods and cross rods, forming multiple triangular stabilizing units. During the jacking process, loads are transferred to the structure below via the vertical rods. Cross rods limit the horizontal displacement of the vertical rods, and diagonal webs disperse local stresses through their triangular anti-deformation properties.

[0024] In other preferred embodiments, Figure 9 and Figure 10As shown, corresponding prefabricated holes are opened on the upper standard section cross bar 3 at the bottom of the upper standard section 1 and the support tube frame cross bar 11 at the top of the support tube frame 9. The connecting piece 1 29 has holes corresponding to the prefabricated holes. The upper standard section 1 and the support tube frame 9 are connected by bolts 28 passing through the holes of the connecting piece 1 29 and the prefabricated holes. Prefabricated holes 2 are opened on the top of the new standard section vertical rod 6 of the new standard section 5 and the bottom of the upper standard section vertical rod 2 of the upper standard section 1 respectively. The connecting piece 2 30 has holes corresponding to the prefabricated holes 2 of the two standard sections. The new standard section 5 and the upper standard section 1 are connected by inserting bolts 28 into the holes.

[0025] Specifically, prefabricated holes are opened simultaneously at the corresponding positions of the upper standard section crossbar 3 and the support cylinder frame crossbar 11, and the hole processing of the connector 29 is completed in advance as an independent component. During installation, the connector 29 is placed between the two crossbars, and its through hole coincides with the axis of the prefabricated hole. By inserting the bolt 28 and applying a pre-tightening force, the connector 29 is fixed in surface contact with the crossbar. This connection method eliminates manual alignment errors through the positioning function of the prefabricated hole, and uses the axial tension of the bolt 28 to generate friction resistance to resist the horizontal shear force during the jacking process. As an independent component, the connector 29 can be mass-produced in the factory to avoid the risk of deformation caused by on-site welding.

[0026] Specifically, the new standard section 5 is pushed in through the open side of the support cylinder frame 9, so that the prefabricated hole 2 at the top of the new standard section vertical rod 6 is vertically aligned with the prefabricated hole 2 at the bottom of the upper standard section vertical rod 2, and then the second connecting piece 30 is placed in the corresponding position, so that the hole position on the second connecting piece 30 is aligned with the two prefabricated holes 2, and finally the bolt 28 is inserted into the hole position and tightened, thereby firmly connecting the new standard section 5 and the upper standard section 1. This ensures that the new standard section 5 is accurately docked with the upper standard section 1 and reduces installation errors.

[0027] Specifically, the standardized first connector 29, second connector 30 and bolts 28 are used for connection, which facilitates on-site installation and disassembly and improves construction efficiency.

[0028] In other preferred embodiments, Figure 7 and Figure 8As shown, the large-scale lifting cylinder 18 includes a large-scale lifting cylinder pressure sensor 19, a large-scale lifting cylinder displacement sensor 20, a large-scale lifting cylinder balancing valve 21, a large-scale lifting cylinder hydraulic pump station 22 and a large-scale lifting cylinder upper support 23; the large-scale lifting cylinder hydraulic pump station 22 provides power, the large-scale lifting cylinder pressure sensor 19 monitors the cylinder pressure value, the large-scale lifting cylinder displacement sensor 20 detects the cylinder stroke, horizontal offset and lifting synchronization, and the large-scale lifting cylinder balancing valve 21 prevents the building construction machine from overspeeding and descending and realizes locking. The movable leg type jacking cylinder 14 includes a movable leg type jacking cylinder jacking section 15, a movable leg type jacking cylinder displacement sensor 16 and a movable leg type jacking cylinder hydraulic oil pump 17; the movable leg type jacking cylinder hydraulic oil pump 17 provides power, the movable leg type jacking cylinder displacement sensor 16 detects horizontal offset and jacking synchronization, and the movable leg type jacking cylinder jacking section 15 is synchronously ejected to ensure that the middle support 13 of the support cylinder frame is lifted.

[0029] Specifically, when the large-scale lifting cylinder hydraulic pump station 22 drives the upper support 23 of the large-scale lifting cylinder to lift, the large-scale lifting cylinder pressure sensor 19 continuously monitors the pressure value of each cylinder. If the pressure difference exceeds the set threshold, the load is evenly distributed by adjusting the output pressure of the pump station. The large-scale lifting cylinder displacement sensor 20 collects the cylinder stroke and horizontal offset data in real time. When asynchrony or offset is detected, the system automatically adjusts the lifting speed of the corresponding cylinder to correct the deviation. The large-scale lifting cylinder balance valve 21 maintains the hydraulic circuit locked state during the lifting process, and immediately locks the oil circuit when the lifting stops to avoid slippage due to gravity or external disturbances. The upper support 23 of the large-scale lifting cylinder is in direct rigid contact with the lower standard section 24, without relying on reserved holes in the wall for fixation, thereby simplifying the construction process.

[0030] Specifically, the hydraulic oil pump 17 of the movable leg-type lifting cylinder drives the extension and retraction of the cylinder lifting section through an independent oil supply system, and the power output is not interfered with by other equipment. The movable leg-type lifting cylinder displacement sensor 16 collects the lifting height and horizontal position deviation of each cylinder in real time, and uploads the data to the central controller. The controller dynamically adjusts the oil supply pressure and flow of the hydraulic oil pump according to the preset threshold value, so that the multiple movable leg-type lifting cylinder lifting sections 15 maintain synchronous movement. When a horizontal offset occurs during the lifting process, the movable leg-type lifting cylinder displacement sensor 16 triggers a correction signal, and compensates for the offset by adjusting the extension and retraction of the corresponding cylinder. When the movable leg-type lifting cylinder lifting section 15 is synchronously ejected, the lifting force is evenly transmitted to the middle support 13 of the support cylinder frame through a rigid connection structure to avoid deformation of the support cylinder frame caused by local stress concentration.

[0031] The construction process of the building crane jacking system includes the following steps: S1. Connect the lower part of the upper standard section 1 with the upper part of the support drum frame 9. The large jacking cylinder 18 and the movable leg jacking cylinder 14 are synchronously lifted upward by 1.5 meters, for a total lifting of 3 meters. S2, push the newly inserted standard section 5 into the support cylinder frame 9 through the opening side, and connect the upper part of the newly inserted standard section 5 to the lower part of the upper standard section 1 through the second connecting piece 30; S3, release the connection between the support cylinder frame 9 and the upper standard section 1, retract the large jacking cylinder 18 and the movable leg type jacking cylinder 14 to their original positions, and complete the jacking of one layer.

[0032] Specifically, for step S1, the lower portion of the upper standard section 1 is connected to the upper portion of the support cylinder frame 9 via a connector 29. Specifically, corresponding prefabricated holes are provided on the upper standard section crossbar 3 at the bottom of the upper standard section 1 and the support cylinder frame crossbar 11 at the top of the support cylinder frame 9. The connector 29 has holes corresponding to the prefabricated holes, and bolts 28 are inserted through the holes in the connector 29 and the prefabricated holes to achieve a secure connection between the two.

[0033] Specifically, in step S1, the large-scale lifting cylinder 18 and the movable-leg lifting cylinder 14 simultaneously lift upward by 1.5 meters. Due to their coordinated operation, the total lift is 3 meters. During the lifting process, the large-scale lifting cylinder hydraulic pump station 22 provides power. Its pressure sensor continuously monitors the cylinder pressure value. The displacement sensor detects the cylinder stroke, horizontal offset, and lifting synchronization. The balance valve prevents the building crane from overspeeding and descending and achieves a lock. The movable-leg lifting cylinder hydraulic pump 17 provides power. The displacement sensor detects horizontal offset and lifting synchronization. The lifting sections are synchronously ejected to ensure the lifting of the central support of the support drum frame, ensuring a stable and synchronized lifting process.

[0034] Specifically, for step S2, after the movable leg-type jacking cylinder 14 and the large jacking cylinder 18 are jointly jacked a certain distance, a channel is formed on the open side of the support drum frame 9, and the newly inserted standard section 5 is pushed into the support drum frame 9 through the open side, so that its lower part is supported on the middle support 13 of the support drum frame. The upper part of the newly inserted standard section 5 is connected to the lower part of the upper standard section 1 through the second connector 30. Specifically, prefabricated holes 2 are respectively opened at the top of the newly inserted standard section upright rod 6 of the newly inserted standard section 5 and the bottom of the upper standard section upright rod 2 of the upper standard section 1. The second connector 30 has hole positions corresponding to the prefabricated holes 2 of the two standard sections. By inserting bolts 28 into the hole positions, the newly inserted standard section 5 and the upper standard section 1 are firmly connected together.

[0035] Specifically, in step S3, the connection between the support cylinder frame 9 and the upper standard section 1 is released by removing the bolts 28 of the connector 29, separating the two. The large jacking cylinder 18 and the movable leg jacking cylinder 14 are retracted to their original positions. At this point, the new standard section 5 has been installed, completing the jacking operation for one floor.

[0036] Specifically, the construction process achieves efficient and stable jacking of the building construction machine through modular design and the coordinated work of the cylinders, thereby improving the construction progress.
