Description

Technical Field

[0001] The utility model relates to the technical field of building construction machines, in particular to a lifting mechanism for a building construction machine platform. Background Art

[0002] Building construction machine is a modern large-scale mechanical equipment platform designed specifically for high-rise and super-high-rise building construction. It integrates a variety of advanced technologies and construction processes to improve the safety, efficiency and quality of building construction.

[0003] As the basic supporting member of the building machine platform, the building machine column is responsible for safely and stably transferring the weight of the entire building machine platform and its load (including construction materials, equipment, tools and operators, etc.) to the ground or the built building structure. The building machine column is usually made of high-strength steel, with sufficient load-bearing capacity and good bending and shear resistance to ensure that the structure can remain stable under extreme working conditions.

[0004] However, the existing building construction machine can only be supported by external fulcrums on the building. The external fulcrums often cause local stress concentration and severe wear due to improper material selection, insufficient processing precision or long-term high-load operation, which leads to insufficient fulcrum strength. Once the fulcrum fails, it is very likely to cause the overall stability of the building construction machine to be damaged, and even induce serious safety accidents.

[0005] At the same time, the existing building construction machine can only be installed by lifting up with the hydraulic cylinder, and can only climb up step by step but cannot descend step by step. After completing the construction task of a certain floor, the existing building construction machine often lacks an effective floor lowering mechanism, and can only be lowered by disassembling the hydraulic cylinder and reversing the installation, which is time-consuming and labor-intensive, and safety cannot be guaranteed.

[0065] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific implementation methods. Figure 2 The orientation is used as a reference.

[0066] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0067] Embodiment 1:

[0068] Reference Figure 2 , Figure 3 and Figure 4A lifting mechanism for a building construction machine platform includes a steel truss composed of multiple vertically detachably connected standard sections 1 and a lifting device 2 which is sleeved on the standard sections 1 and can be lifted and lowered along the longitudinal direction of the steel truss.

[0069] The lifting device 2 includes a support unit 21 and a lifting unit 22 which can be telescopically connected to each other between a first working position, a second working position, a third working position and a fourth working position. The support unit 21 is located above the lifting unit 22 and is detachably connected to the building machine column 3. The support unit 21 and the lifting unit 22 both have a fourth limiting structure which is detachably connected to the first limiting structure, the second limiting structure and the third limiting structure on the standard section 1; in the same standard section, the heights of the third limiting structure, the second limiting structure and the first limiting structure decrease successively.

[0070] When the supporting unit and the lifting unit are located at the first working position: the vertical distance between the fourth limiting structures of the supporting unit 21 and the lifting unit 22 is the vertical distance between the first limiting structure of the upper standard section 1 and the second limiting structure of the lower standard section 1 of two adjacent standard sections 1.

[0071] When the supporting unit and the lifting unit are located at the second working position: the vertical distance between the fourth limiting structures of the supporting unit 21 and the lifting unit 22 is the vertical distance between the second limiting structures in two adjacent standard sections 1.

[0072] When the supporting unit and the lifting unit are located at the third working position: the vertical distance between the fourth limiting structures of the supporting unit 21 and the lifting unit 22 is the vertical distance between the second limiting structure of the upper standard section 1 and the third limiting structure of the lower standard section 1 of the two adjacent standard sections 1.

[0073] When the supporting unit and the lifting unit are located at the fourth working position: the vertical distance between the fourth limiting structures of the supporting unit 21 and the lifting unit 22 is the vertical distance between the second limiting structures on the standard sections at both ends of the three standard sections 1.

[0074] By subdividing the lifting device into a support unit and a lifting unit, and enabling them to be precisely telescopically connected between multiple preset working positions, refined control of the lifting height is achieved. This design allows the position of the building construction machine platform to be fine-tuned during the construction process, ensuring the precise positioning of the platform when working at different heights, and improving the accuracy and safety of construction.

[0075] Since the support unit and lifting unit can be connected to different limit structures on the standard section, and these limit structures are regularly distributed on the standard section, the lifting mechanism can adapt to the adjustment requirements of different heights. This flexibility not only improves the applicability of the equipment under various construction conditions, but also simplifies the maintenance and adjustment process.

[0076] The carefully designed limit structure layout and precise setting of vertical distance ensure the stable docking of the structure during the lifting process, reduce unnecessary shaking or deviation, and improve the stability of the overall structure. In addition, this design also helps to disperse the load, reduce the pressure on a single connection point, and further improve construction safety.

[0077] The lifting device can quickly switch between the first to fourth working positions, which means that the building construction machine can complete the climbing and descending actions between floors more efficiently without the need for frequent disassembly and reassembly of key components, greatly shortening the construction period and improving work efficiency.

[0078] Reference Figure 2 , Figure 3 and Figure 4 , the lifting device 2 has the installation status with the standard section 1:

[0079] The lifting unit 22 and the supporting unit 21 are in the first working position, and the fourth limiting structure of the lifting unit 22 is connected to the second limiting structure of the second standard section at the top of the steel truss; the fourth limiting structure of the supporting unit 21 is disconnected from the first limiting structure of the first standard section 1 at the top of the steel truss;

[0080] The support unit 21 extends upward to the fourth working position relative to the lifting unit 22, the new standard section 1 is placed into the support unit 21 and detachably spliced ​​with the original first standard section 1, and the fourth limiting structure of the support unit 21 is connected with the second limiting structure of the new standard section 1;

[0081] The lifting unit 22 extends upward to a third working position relative to the supporting unit 21, and the fourth limiting structure of the lifting unit 22 is aligned with the third limiting structure of the original topmost standard section 1;

[0082] The lifting unit 22 extends downward relative to the supporting unit 21 to connect with the second limiting structure of the original topmost standard section 1, and releases the connection between the fourth limiting structure of the supporting unit 21 and the second limiting structure of the new standard section 1;

[0083] The support unit 21 extends downward to the first working position relative to the lifting unit 22 , and the fourth limiting structure of the support unit 21 is connected to the first limiting structure of the new standard section 1 .

[0084] Reference Figure 2 , Figure 3 and Figure 4, the lifting device 2 is in a disassembled state from the standard section 1. The lifting unit 22 and the support unit 21 are in the first working position, the fourth limiting structure of the lifting unit 22 is connected to the second limiting structure of the second standard section 1 at the top of the steel truss, and the fourth limiting structure of the support unit 21 is disconnected from the first limiting structure of the standard section 1 at the top of the steel truss.

[0085] The support unit 21 extends upward to the second working position relative to the lifting unit 22, and the fourth limiting structure of the support unit 21 is connected to the second limiting structure of the first standard section at the top of the steel truss.

[0086] The connection between the fourth limiting structure of the lifting unit 22 and the second limiting structure of the second standard section 1 at the top of the steel bar truss is released, and the lifting unit 22 is moved upward and retracted to the third working position.

[0087] The mobile lifting unit 22 extends downward to the fourth working position, and the fourth limiting structure of the lifting unit 22 is connected to the second limiting structure of the third standard section 1 at the top of the steel truss, and the connection between the fourth limiting structure of the support unit 21 and the second limiting structure of the first standard section at the top of the steel truss is released. At this time, the first standard section at the top of the steel truss can be removed.

[0088] The support unit 21 extends downward to the first working position relative to the lifting unit 22 , and the fourth limiting structure of the support unit 21 is connected to the first limiting structure of the original second standard section 1 .

[0089] The lifting unit 22 is limitedly connected with the steel truss, and the supporting unit 21 moves upward until it exceeds the height of at least one standard section 1 at the top of the steel truss, and the new standard section 1 is placed inside the supporting unit 21 and detachably spliced ​​with the existing steel truss. The lifting device 2 performs a descending operation, the lifting unit 22 is limitedly connected with the second highest standard section 1, and the supporting unit 21 moves upward until there is a gap with the uppermost standard section of the steel truss (the gap is convenient for inserting and removing the standard section) and is limitedly connected with this standard section 1, the lifting unit 22 is released from the limited connection with the steel truss and the lifting unit 22 is moved to the lower end of the supporting unit 21; the lifting unit 22 descends to the third highest standard section 1 and is limitedly connected with it, the limited connection of the supporting unit 21 is released, the standard section 1 in the supporting unit 21 is removed, and the supporting unit 21 is lowered to the upper part of the lifting unit 22.

[0090] Through the coordinated work of the support unit 21 and the lifting unit 22, the automatic lifting function of the building machine platform is realized, which can not only climb up step by step, but also descend step by step, greatly improving the flexibility and efficiency of construction. Compared with traditional equipment that can only climb up step by step, this lifting mechanism simplifies the complexity of switching between floors and reduces the time and labor cost required for switching.

[0091] The lifting device 2 ensures the stability of the structure during the lifting process through the limit connection with the steel truss. Especially during the rising and falling operations, the precise positioning and limit connection avoids shaking and deviation during the lifting process, improving the safety of the operation. The interaction mechanism between the support unit and the lifting unit ensures a smooth transition during the entire operation process and reduces the potential risks caused by equipment operation.

[0092] The steel truss composed of multiple vertically detachably connected standard sections 1 and the detachable connection characteristics of the lifting device 2 used in the lifting mechanism design are conducive to modular construction. This means that the number of standard sections can be flexibly increased or decreased according to different building heights and construction requirements, which is convenient for transportation and installation, and also conducive to rapid assembly and disassembly on site, enhancing the standardization of construction, facilitating reuse and reducing overall costs.

[0093] As a highly stable structural system, the steel truss provides a solid support frame for the entire lifting mechanism. It can effectively bear and transfer the huge weight generated by the building machine platform and its load and various loads generated during the construction process to the lower structure, ensuring construction safety and structural stability.

[0094] Through the coordination of the steel truss and the lifting device, the lifting mechanism can be smoothly raised and lowered, avoiding the potential safety hazards in traditional methods, such as the risks caused by frequent disassembly and assembly of hydraulic cylinders, and improving the overall safety of the construction process. The integrated design of the steel truss and the lifting mechanism, especially its detachable connection and limit connection mechanism, can form a self-contained system without relying on external building structures, effectively replacing traditional external fulcrums, solving the local stress concentration and wear problems caused by material or processing problems of external fulcrums, and enhancing the reliability and durability of the overall structure.

[0095] Reference Figure 1 and Figure 2 The support unit 21 and the lifting unit 22 are detachably connected and can move relative to each other; the lifter 222 in the lifting unit 22 can be fixedly connected to the support unit 21.

[0096] The support unit 21 is generally sleeved on the uppermost standard section of the steel truss, and the lifting unit 22 is located on the second highest or third highest standard section 1 of the steel truss.

[0097] Both the support unit 21 and the lifting unit 22 can be connected to the steel truss in a limiting manner, and the lifting unit 22 provides lifting force for the support unit 21 and the lifting unit 22, so as to realize the lifting of the building construction machine carried by the support unit 21.

[0098] The support unit 21 is connected to the uppermost standard section of the steel truss and the lifting unit 22 is connected to the other standard sections of the steel truss to ensure stability and safety during the entire lifting process. This method of directly connecting to the steel truss structure can more evenly distribute the load, reduce local stress concentration, and reduce the risk of structural instability during construction than relying on external support points.

[0099] The lifting unit 22 not only provides lifting power for itself, but also drives the support unit 21 to lift, which means that the lifting operation of the entire building construction machine platform becomes more unified and efficient. This design avoids the operational complexity and time consumption caused by the separation of lifting and supporting structures in traditional methods, and improves construction efficiency.

[0100] Both the support unit and the lifting unit can be connected to the steel truss in a limited position. This feature ensures the precise positioning of the equipment during the lifting process, which is very useful for aligning the floor height and ensuring the completion of the construction in high-rise building construction. In addition, this design can adapt to different heights and structural changes, improving the adaptability of the equipment in a variety of construction projects.

[0101] In addition, the plurality of support units 21 themselves can support the building construction machine, but in order to reduce fatigue of the support units 21, the support of the building construction machine by the support units 21 themselves is reduced as much as possible and replaced with a steel truss for support.

[0102] Reference Figure 1 and Figure 2 The lifting unit 22 includes a base 221, a lifter 222 and two guide rods 223 parallel to the lifter 222.

[0103] The base 221 can be limitedly connected to the standard section 1; one end of the lifter 222 is installed on the base 221, and the other end of the lifter 222 can be detachably connected to the support unit 21. A flange or a lifting ring is set in the middle slot hole for detachable connection or fixed connection. The telescopic end is directly welded to the middle slot hole, or the middle slot hole is cancelled, and the lifter 222 is directly connected to the bottom of the flange 214, or the lifter 222 is directly welded to the top of the flange 214, so as to ensure that the flange 214 can be close to the C-shaped plate.

[0104] Two guide rods 223 are installed at the upper end of the base 221 and are located at the front and rear sides of the lifter 222. The guide rods 223 pass through the side of the support unit 21, and can guide the support unit 21 and the lifting unit 22 to move up and down, and there is a gap between the guide rods 223 and the lifter 222.

[0105] The guide rod 223 and the lifter 222 are used in conjunction with each other, and by penetrating the slots on the side of the support unit 21 and providing guidance during the lifting process, the stability and accuracy of the lifting operation are effectively increased, the risk of deflection during the lifting process is reduced, and the operating safety of the entire building construction machine platform is improved. By setting the guide rod, the lifting unit can automatically align and maintain the correct position when moving up and down, simplifying the lifting operation process, reducing the need for manual adjustment, and thus improving construction efficiency.

[0106] The reserved gap design between the lifter and the guide rod helps to reduce direct contact and friction between components, reduce the degree of wear under long-term use, and prevent interference between them. It extends the service life of the lifter and reduces maintenance costs.

[0107] The lifter 222 is preferably a common hydraulic cylinder, which can be unidirectional or bidirectional. One end of the support unit 21 and the lifter 22 is fixed to the steel truss, and the other end is separated from the steel truss. The relative movement of the two is achieved by the cylinder drive. The lower end of the cylinder can be located in the C-shaped plate and directly fixedly connected to the lower end of the C-shaped plate 2211.

[0108] Reference Figure 1 , Figure 2 and Figure 5 Two fourth limiting structures 212 are arranged transversely on the base 221, and the fourth limiting structures 212 can be connected to the standard section 1 in a limitable manner.

[0109] The lifter 222 is located between the two fourth limiting structures 212 and has a gap between the two fourth limiting structures 212 .

[0110] When the fourth limiting structure 212 is connected to the standard section 1 in a limiting manner, the lifter 222 can support the support unit 21 to lift upward or can drive the support unit 21 to move closer to the lifting unit 22;

[0111] When the fourth limiting structure 212 is released from the limiting connection with the standard section 1 , the base 221 can move toward the support unit 21 or away from the support unit 21 under the action of the lifter 222 .

[0112] The fourth limiting structure is a telescopic oil cylinder. When in the extended state, the telescopic end is inserted into the positioning hole of the standard section as a positioning pin for limiting connection.

[0113] The limitable connection design of the fourth limit structure 212 and the standard section 1 ensures the precise alignment and stable connection of the lifting unit during installation and operation, and improves the stability and safety of the entire lifting system. When the limit connection component is locked, it can provide a solid support base point for the lifter 222, ensuring the smooth and accurate lifting action, especially when lifting upward or driving the support unit 21 to move.

[0114] Reference Figure 1 , Figure 2 and Figure 3 The support unit 21 is in an inverted U shape and is sleeved outside the top of the steel truss.

[0115] A hole 213 is provided in the middle of the top plate of the support unit 21, and the position of the hole 213 corresponds to the central hole of the building construction machine column 3, so as to achieve rapid positioning.

[0116] Two fourth limiting structures 212 are respectively disposed on the outer surfaces of the supporting plates 211 on the left and right sides of the supporting unit 21 and are transversely arranged to penetrate the supporting plates 211 . The fourth limiting structures 212 can be connected to the standard section 1 in a limiting manner.

[0117] The fourth limiting structure 212 in the supporting unit 21 and the fourth limiting structure 212 in the lifting unit are located in the same vertical plane.

[0118] When the fourth limiting structure 212 is connected to the standard section 1 in a limiting manner, the lifter 222 can drive the lifting unit 22 to move toward the supporting unit 21 or can support the lifting unit 22 to move away from the supporting unit 21 .

[0119] When the fourth limiting structure 212 is released from the limiting connection with the standard section 1 , the lifter 222 can drive the support unit 21 to move toward the lifting unit 22 or can support the support unit 21 to move away from the lifting unit 22 .

[0120] The inverted U-shaped design of the support unit 21 and the corresponding arrangement of the hole 213 on the top and the central hole of the building construction machine column 3 ensure that the support unit can be accurately docked on the column, improving the installation accuracy and stability of the entire building construction machine platform. This docking method simplifies the installation process, reduces the alignment time, and enhances the load-bearing capacity and safety of the structure.

[0121] The limitable connection mechanism between the fourth limit structure 212 on the support unit 21 and the standard section 1 provides flexibility for motion control during the lifting process. By locking and unlocking these limit components, the relative position change between the support unit and the lifting unit 22 can be accurately controlled to achieve upward climbing, downward movement, or horizontal convergence and separation, thereby improving the flexibility and efficiency of the operation.

[0122] The fourth upper limiting structure 212 and the fourth lower limiting structure 212 are located on the same vertical line, and this collaborative working mode enhances the stability of the entire lifting system. When the components are in the limiting state, it can ensure that the support unit or the lifting unit is stable and immovable at the predetermined position, and the structure can be kept stable even when subjected to heavy loads or changes in the external environment, greatly improving construction safety.

[0123] Reference Figure 1 and Figure 2 The base 221 includes two C-shaped plates 2211 arranged opposite to each other, and the grooves of the C-shaped plates 2211 are away from the direction of the standard section 1; two guide rods 223 perpendicular to the upper plate of the C-shaped plate 2211 are installed on the front and rear sides of the upper plate of the C-shaped plate 2211, and the two guide rods 223 can pass through the sides of the support unit 21 to realize the longitudinal guidance of the support unit 21 and the lifting unit 22.

[0124] The C-shaped plate 2211 is fixedly connected with a lifter 222 which sequentially penetrates the lower plate and the upper plate of the C-shaped plate 2211, and the end of the telescopic end of the lifter 222 is fixedly connected or detachably connected to the support unit 21. The fixed end of the lifter 222 is relatively fixed to the C-shaped plate 2211, so when the telescopic end moves, the C-shaped plate 2211 can be driven to move longitudinally.

[0125] Two fourth limiting structures 212 are provided in the C-shaped plate 2211 and are vertical plates penetrating the C-shaped plate 2211 . The fourth limiting structures 212 can be connected to the standard section 1 in a limiting manner.

[0126] The structural design of the C-type plate 2211, especially its notch deviating from the direction of the standard section, provides the base with additional stability and fit to the standard section. At the same time, the guide rod 223 vertically installed on the upper plate of the C-type plate passes through the side of the support unit 21, ensuring the precise guidance of the support unit and the lifting unit when they move up and down, reducing deflection and shaking, and improving the accuracy and safety of the operation.

[0127] Reference Figure 1 The bottoms of the support plates 211 on the left and right sides of the support unit 21 are bent outward to form a convex edge 214, and three vertical slots are spaced apart along the length direction of the convex edge 214. The two slots on the edge penetrate the convex edge 214, and the middle slot enters from the lower surface and extends upward to the inside of the convex edge 214.

[0128] The two slots at the edge can be penetrated by two guide rods 223 to achieve longitudinal guidance of the support unit 21 and the lifting unit 22 .

[0129] The interior of the middle slot is fixedly connected or detachably connected to the lifter 222 to drive the lifting unit or the supporting unit to move longitudinally.

[0130] The convex edge 214 at the bottom of the support plate 211 is designed to increase the rigidity of the structure through bending, which can more effectively disperse the pressure and reduce deformation when carrying heavy objects, thereby enhancing the stability and load-bearing capacity of the entire support unit.

[0131] The two slots on the edge are connected to the guide rods of the lifting unit 22 through the guide rods 223, ensuring the precise guidance of the support unit during the lifting process, avoiding deviation and shaking, and improving the accuracy and safety of the lifting operation. This design simplifies the guiding mechanism and makes the operation smoother and more stable.

[0132] Reference Figure 6 The inner surface of the support unit 21 and the vertical plate of the C-shaped plate 2211 are both installed with multiple angle steel guide wheel groups 224 near the side surface of the steel truss. The angle steel guide wheel groups 224 are in contact with the standard section 1 and can guide the support unit 21 or the C-shaped plate 2211 to move along the extension direction of the standard section 1.

[0133] The angle steel guide wheel group 224 includes a first guide wheel component 2241 and a second guide wheel component 2242 hinged to the first guide wheel component 2241. The first guide wheel component 2241 is installed on the inner surface of the support plate 211 and the vertical plate of the C-shaped plate 2211 close to the side surface of the steel truss. The second guide wheel component 2242 can rotate 90 degrees clockwise or counterclockwise around the hinge axis hinged to the first guide wheel component 2241.

[0134] The first guide wheel component 2241 in the angle steel guide wheel assembly and the second guide wheel component 2242 hinged to the first guide wheel component 2241 can be universal wheels as long as no interference occurs when the standard section is removed and placed.

[0135] The close contact between the angle steel guide wheel group 224 and the standard section 1 effectively reduces the friction and resistance during the movement, so that the support unit 21 and the C-shaped plate 2211 can move smoothly along the steel truss, improving the smoothness and positioning accuracy of the lifting operation.

[0136] The first guide wheel component 2241 and the rotatable second guide wheel component 2242 are combined to form a flexible guide system. The 90-degree rotation capability of the second guide wheel component enables the guide wheel group to adjust its posture as needed to avoid interference with the standard section.

[0137] The stable guiding and shock-absorbing function of the guide wheel group reduces the risk of accidents caused by vibration or misalignment during lifting operations, further ensuring the safety of operators and the stability of the entire construction process.

[0138] Reference Figure 1-Figure 5 Two vertically distributed rows of limiting structures are provided on each connecting plate, and at least three rows of limiting structures are arranged horizontally; the limiting structures include a first limiting structure, a second limiting structure and a third limiting structure; the first limiting structure, the second limiting structure and the third limiting structure correspond to the fourth limiting structure 212.

[0139] The first limiting structure, the second limiting structure and the third limiting structure are connection holes set on the standard section. The connection holes are evenly distributed along the longitudinal direction. The connection holes directly on each standard section are not limited to three rows, and can be adaptively adjusted according to the height of the standard section, the extension and contraction of the oil cylinder and the size of the supporting force.

[0140] The fourth limiting structure is a bolt or a hydraulic cylinder.

[0141] The connection holes can also be used as positioning holes. The precise correspondence of the positioning holes enables the limit connection components to be firmly embedded, ensuring the structural stability of the entire building construction machine platform during the lifting process. This tight connection avoids vibration or shaking caused by component misalignment and improves operational safety. Since the positioning holes are distributed vertically and arranged in multiple rows horizontally, it means that different hole positions can be selected for connection according to the specific construction height and structural requirements.

[0142] Reference Figure 4 The lifting mechanism also includes a cement foundation, which is fixed on the base surface, and the lowest standard section 1 is fixedly connected to the cement foundation.

[0143] Multiple cement foundations are evenly distributed on the left and right sides of the high-rise building.

[0144] Each cement foundation is fixedly connected to each steel truss with a lifting device 2.

[0145] The mud foundation is directly fixed on the base surface and firmly connected to the lowest standard section 1, forming a solid foundation support structure. This design significantly enhances the stability of the entire building machine system, ensuring that it can safely bear huge vertical loads and lateral forces such as wind pressure and construction loads during high-rise building construction, reducing the risk of structural deformation.

[0146] Multiple cement foundations are evenly distributed on the left and right sides of the high-rise building. This layout strategy helps to evenly disperse the huge pressure generated during the construction process, avoid local overload, and further improve the stability and safety of the overall structure. At the same time, the balanced distribution also helps to reduce the problem of uneven foundation settlement and protect surrounding buildings and infrastructure from being affected.

[0147] Each cement foundation is fixedly connected to a steel truss with a lifting device, which means that each independent lifting unit can be operated separately, improving the flexibility and efficiency of construction. When it is necessary to carry out construction at multiple points at the same time or to carry out construction in different areas in stages, this layout can effectively speed up the construction progress and reduce waiting time.

[0148] The positioning of traditional external fulcrums depends on the specific apartment type, and the fulcrum position needs to be designed separately for each project, which is not only time-consuming and labor-intensive, but also difficult to achieve large-scale production and construction. The uniform distribution of cement foundation skips this tedious process. There is no need to consider the positioning of each fulcrum one by one, but it is directly planned based on the overall layout of the building, which greatly speeds up the design cycle and reduces the workload of customization.

[0149] The working principle of the lifting mechanism of the building construction machine platform:

[0150] At the initial stage, the lifting mechanism of the building construction machine is installed on a steel truss foundation supported by a cement foundation, ready to carry out the raising or lowering operation of the floor.

[0151] Lifting mechanism rising process (standard section added):

[0152] Step 1: Starting position setting; standard sections are pre-installed on the cement foundation to form a steel truss, and the lifting mechanism is in place. Ensure that the lifting unit 22 and the support unit 21 are in the first working position. At this time, the fourth limiting structure of the lifting unit 22 is tightly connected to the second limiting structure of the second standard section at the top of the steel truss. At the same time, the connection between the support unit 21 and the first limiting structure of the first standard section at the top of the steel truss is released, and the new standard section is ready to be installed.

[0153] Step 2: Lift the support unit; operate the support unit 21 to extend upward relative to the lifting unit 22 until it reaches the fourth working position. During this process, the new standard section is placed inside the support unit 21 and detachably spliced ​​with the first standard section originally located at the top. Next, adjust the fourth limiting structure of the support unit 21 to connect with the second limiting structure of the new standard section to ensure that the two are firmly connected.

[0154] Step 3: The lifting unit is adjusted to the third working position; next, the lifting unit 22 extends upward relative to the support unit 21 until its fourth limiting structure is aligned with the third limiting structure of the standard section previously located at the top. This operation prepares for the next step of descent and ensures a smooth transition of the subsequent steps.

[0155] Step 4: Then, carefully extend the lifting unit 22 relative to the support unit 21 until its fourth limiting structure is reconnected with the second limiting structure of the original topmost standard section. At this time, the connection between the support unit 21 and the second limiting structure of the new standard section is released to prepare for the final positioning.

[0156] Step 5: Final positioning and locking: Finally, the support unit 21 extends downward relative to the lifting unit 22 and returns to the first working position. At this position, the fourth limiting structure of the support unit 21 is precisely docked and locked with the first limiting structure of the new standard section, completing the installation of the new standard section.

[0157] Lifting mechanism lowering process (standard section removed):

[0158] Step 1: Initial arrangement: Ensure that the lifting unit 22 and the support unit 21 are in the first working position, wherein the fourth limiting structure of the lifting unit 22 is connected to the second limiting structure of the second standard section at the top of the steel truss. Release the connection between the support unit 21 and the first limiting structure of the current topmost standard section (i.e., the standard section to be removed) to prepare for the removal operation.

[0159] Step 2: The support unit is adjusted to the second working position; the support unit 21 extends upward to the second working position relative to the lifting unit 22, so that the fourth limiting structure of the support unit 21 is connected to the second limiting structure of the standard section to be removed. This step is to stabilize the upper structure and create safety conditions for the lower operation.

[0160] Step 3: Adjust the lifting unit; release the connection between the fourth limiting structure of the lifting unit 22 and the second limiting structure of the current second standard section (which will become the top standard section in the future), and then carefully retract the lifting unit 22 upward to the third working position.

[0161] Step 4: The lifting unit 22 needs to continue to extend downward to the fourth working position, and its fourth limiting structure is connected to the second limiting structure of the third standard section which now becomes the top standard section.

[0162] Step 5: Return to the original position; the support unit 21 extends downward to the first working position relative to the lifting unit 22. At this time, the fourth limiting structure of the support unit 21 is reconnected and locked with the first limiting structure of the new top standard section (i.e., the original second standard section) to ensure the stability and safety of the entire steel truss structure.
