Description

Technical Field

[0001] This invention relates to the field of construction machinery technology for super high-rise buildings, specifically an intelligent lifting system and method for an attached lifting scaffold combined with an assembled unloading platform. Background Technology

[0002] In the construction of super high-rise structures, unloading platforms are often used to transport materials between floors. However, traditional unloading platforms, as independent devices from attached lifting scaffolding, require the use of a tower crane to dismantle them before the attached lifting scaffolding is raised, and then the unloading platform is reinstalled using a tower crane after the attached lifting scaffolding is raised. This traditional method is time-consuming, labor-intensive, and requires a tower crane. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent lifting system for attached lifting scaffolding in conjunction with an assembled unloading platform, including an unloading platform, lifting scaffolding, reinforcing steel wire ropes, and retractable steel wire ropes.

[0004] The unloading platform and the lifting scaffold are connected by reinforcing steel wire ropes and retractable steel wire ropes.

[0005] The unloading platform includes a boom and a platform base.

[0006] The cantilever is fixed to the platform base plate and can extend and retract along the length of the cantilever.

[0007] Under operating conditions:

[0008] The cantilever is in an extended state, with one end fixed to the platform base plate and the other end fixed to the main structure. The main structure fixedly connected to the cantilever is referred to as main structure I.

[0009] One end of the reinforcing wire rope and the retractable wire rope is fixed to the platform base plate, and the other end is fixed to the main structure and the lifting scaffold, respectively. The main structure fixedly connected to the reinforcing wire rope is referred to as Main Structure II.

[0010] At this point, the platform base is perpendicular to the length direction of the lifting scaffold.

[0011] Under lifting conditions:

[0012] The cantilever is in a retracted state and fixed to the platform base plate.

[0013] One end of the reinforcing wire rope and the retractable wire rope is fixed to the platform base plate, and the other end is fixed to the lifting scaffold.

[0014] At this point, the platform base plate is parallel to the length direction of the lifting scaffold.

[0015] Furthermore, the extended end of the lever is equipped with a press-type elastic self-locking mechanism.

[0016] Under operating conditions, the extended end of the boom is fixed twice to the anchoring end of the main structure I through a press-type elastic self-locking mechanism.

[0017] Furthermore, the cantilever includes a main beam and a sleeve fixed to the platform base plate.

[0018] The main beam is inserted into the sleeve and can extend and retract within the sleeve.

[0019] Under operating conditions, the main beam extends out of the sleeve, and one end of the extension is fixed to the main structure I.

[0020] Under lifting conditions, the main beam retracts into the sleeve.

[0021] Furthermore, the platform base plate is equipped with platform railings on three sides away from the lifting scaffold.

[0022] The platform fence and the platform base are nested together by hinges.

[0023] The railings of the adjacent platforms are secured together by pins.

[0024] Furthermore, the platform fence and the nested rod of the platform base plate are welded to the platform base plate and protrude from the surface of the platform base plate, so that the platform fence leans inward during the lifting operation.

[0025] Furthermore, the sleeve has symmetrical through holes on its sidewall, and a one-way check mechanism is provided at each through hole.

[0026] The one-way check mechanism includes a steel plate, a bearing, and a spring.

[0027] The one-way check valve and the sleeve are connected by a bearing.

[0028] A spring is installed inside the bearing.

[0029] During the lifting operation, the main beam retracts into the sleeve, at which point the spring is compressed, causing the steel plate to retract inward and fit tightly against the sleeve.

[0030] When in use, the main beam extends out of the sleeve, at which point the spring pops out, causing the steel plate to rotate around the bearing, thereby abutting against the platform railing.

[0031] Furthermore, the platform base plate is made of steel plate.

[0032] Furthermore, the system is equipped with at least two reinforcing steel wire ropes, one of which is equipped with a force gauge.

[0033] When the force gauge reading exceeds the threshold, the platform base plate is overloaded, the warning light on the platform base plate flashes, and the signal transmitter on the lifting scaffold sends an alarm signal to the signal receiver installed in the general contractor's office.

[0034] Furthermore, an electric winch is installed at the fixed position of the retractable steel wire rope and the lifting scaffold.

[0035] Another objective of this invention is to provide a lifting method for an intelligent lifting system based on an attached lifting scaffold and an assembled unloading platform, comprising the following steps:

[0036] 1) Remove the load from the platform base plate;

[0037] 2) Remove the fixing pins between the adjacent platform railings;

[0038] 3) Loosen the anchorage between the main beam and the main structure I, and push the main beam back into the sleeve;

[0039] The one-way check mechanism tightens as the main beam contracts and enters the sleeve, causing the platform railing to fall inward in one direction.

[0040] 4) Loosen the reinforcing wire ropes fixed to the main structure II, and then tie the reinforcing wire ropes to the lifting scaffold;

[0041] Start the electric winch to retract the wire rope. The retracting wire rope drives the platform base plate to rotate, so that the platform base plate is attached to the lifting scaffold.

[0042] 5) Lifting and raising the scaffolding;

[0043] 6) After the scaffolding is raised to the construction position, control the winch to release the platform base plate until the platform base plate is perpendicular to the scaffolding.

[0044] Next, pull the main beam out of the sleeve and lock it to the structure.

[0045] 7) Secure the reinforcing steel wire rope to the structural floor, and then secure the connection between the adjacent platform railings with pins.

[0046] The technical effects of this invention are undeniable, and its beneficial effects are as follows:

[0047] (1) The present invention is connected to the structure by a cantilever beam, and a self-locking buckle is provided on the cantilever beam, which makes the connection with the structure tighter and the buckle easier to disassemble.

[0048] (2) The present invention adopts a modular retractable finished unloading platform, which is simple to assemble and can be reused for multiple projects.

[0049] (3) The present invention adopts a real-time monitoring system. When in use, the platform load is monitored in real time and can issue early warning signals, thereby realizing the digitalization and real-time management of projects.

[0050] (4) The present invention is a dynamic system with two dynamic changes: working condition and lifting condition. In the lifting condition, the system rises with the climbing frame and remains tightly attached to the climbing frame, avoiding the increase of invalid project time, reducing the use of tower cranes, reducing the lifting load of the climbing frame, and reducing safety risks.

[0051] (5) The system features a green construction measure that retracts the unloading platform working surface during the construction of the climbing scaffold, monitors and warns against violations such as overloading, and meets the construction direction of green, safe and civilized construction. The self-retracting working state of the system during the climbing scaffold lifting effectively reduces the kinetic energy required for climbing scaffold lifting, reduces construction risks, optimizes the climbing scaffold lifting process, and significantly saves construction time.

[0060] The present invention will be further described below with reference to embodiments, but it should not be construed that the scope of the present invention is limited to the following embodiments. Various substitutions and modifications made based on ordinary technical knowledge and common practices in the art without departing from the above-described technical concept of the present invention should be included within the scope of protection of the present invention.

[0061] Example 1:

[0062] An intelligent lifting system for attached lifting scaffolding and assembled unloading platform includes an unloading platform, lifting scaffolding, reinforcing steel wire rope 6, and retractable steel wire rope 7.

[0063] The unloading platform and the lifting scaffold are connected by reinforcing steel wire rope 6 and retractable steel wire rope 7.

[0064] The unloading platform includes a boom 1 and a platform base plate 5.

[0065] The cantilever 1 is fixed on the platform base plate 5 and can extend and retract along the length of the cantilever 1.

[0066] See Figure 3 a. Under operating conditions:

[0067] The cantilever 1 is in an extended state, with one end fixed to the platform base plate 5 and the other end fixed to the main structure. The main structure fixedly connected to the cantilever 1 is referred to as the main structure I801.

[0068] One end of the reinforcing wire rope 6 and the retractable wire rope 7 are fixed to the platform base plate 5, and the other end is fixed to the main structure and the lifting scaffold, respectively. The main structure fixedly connected to the reinforcing wire rope 6 is referred to as the main structure II802. When multiple reinforcing wire ropes 6 are installed, each reinforcing wire rope 6 is fixed to a different main structure II802.

[0069] The main structure II802 is located above the main structure I801.

[0070] At this time, the platform base plate 5 is perpendicular to the length direction of the lifting scaffold.

[0071] See Figure 3 b, Under lifting conditions:

[0072] The cantilever 1 is in a retracted state and fixed to the platform base plate 5.

[0073] The reinforcing wire rope 6 and the retractable wire rope 7 are fixed at one end to the platform base plate 5 and at the other end to the lifting scaffold.

[0074] At this time, the platform base plate 5 is attached to the lifting scaffold, and the platform base plate 5 is parallel to the length direction of the lifting scaffold.

[0075] Example 2:

[0076] The main structure of this embodiment is the same as that of embodiment 1. Furthermore, the extended end of the lifting rod 1 is provided with a press-type elastic self-locking mechanism.

[0077] Under operating conditions, the extended end of the boom 1 is fixed twice to the anchoring end of the main structure I801 through a press-type elastic self-locking mechanism.

[0078] Example 3:

[0079] The main structure of this embodiment is the same as any one of embodiments 1 to 2. Furthermore, the cantilever 1 includes a main beam 101 and a sleeve 102 fixed on the platform base plate 5.

[0080] The main beam 101 is inserted into the sleeve 102 and can extend and retract within the sleeve 102.

[0081] Under operating conditions, the main beam 101 extends out of the sleeve 102, and one end of the extension is fixed to the main structure I801.

[0082] Under lifting conditions, the main beam 101 retracts into the sleeve 102.

[0083] Example 4:

[0084] The main structure of this embodiment is the same as any one of embodiments 1 to 3. Further, see [link to embodiment 1]. Figure 2 The platform base plate 5 is equipped with platform railings 3 on three sides away from the lifting scaffold.

[0085] The platform fence 3 and the platform base plate 5 are nested together by hinges.

[0086] The adjacent two platform railings 3 are fixed together by pins 4.

[0087] Example 5:

[0088] The main structure of this embodiment is the same as that of embodiment 4. Furthermore, the nested rods of the platform fence 3 and the platform base plate 5 are welded to the platform base plate 5 and protrude from the surface of the platform base plate 5, so that the platform fence 3 leans inward during the lifting operation.

[0089] Example 6:

[0090] The main structure of this embodiment is the same as any one of embodiments 4 to 5. Furthermore, through holes are symmetrically opened on the side wall of the sleeve 102, and a one-way check mechanism 10 is provided at the through holes.

[0091] The one-way check mechanism 10 includes a steel plate, a bearing, and a spring.

[0092] The one-way check mechanism 10 and the sleeve 102 are connected by bearings.

[0093] A spring is installed inside the bearing.

[0094] By adding a spring inside the bearing to connect the check mechanism and the sleeve, the working principle is equivalent to adding a prestress (like the working principle of a wind-up frog). When the main beam is compressed into the sleeve, the spring inside the bearing is deformed, generating mechanical potential energy. After the main beam extends, the potential energy is converted into kinetic energy, and at the same time, it generates a certain amount of back pressure on the main beam, avoiding the construction risks caused by the unexpected contraction of the main beam.

[0095] Under lifting conditions, the main beam 101 is retracted into the sleeve 102. At this time, the spring is compressed, causing the steel plate to retract inward and fit tightly against the sleeve 102.

[0096] When in use, the main beam 101 extends out of the sleeve 102, at which point the spring pops out, causing the steel plate to rotate around the bearing, thereby abutting against the platform railing 3.

[0097] Example 7:

[0098] The main structure of this embodiment is the same as any one of embodiments 1 to 6. Furthermore, the platform base plate 5 is a steel plate.

[0099] Example 8:

[0100] The main structure of this embodiment is the same as any one of embodiments 1 to 7. Furthermore, the system is provided with at least two reinforcing steel wire ropes 6, and a contraction steel wire rope 7 is located between the reinforcing steel wire ropes 6. A force gauge is provided on one of the reinforcing steel wire ropes 6.

[0101] When the force gauge reading exceeds the threshold (platform weight limit 800kg), the platform base plate 5 is overloaded, the warning light on the platform base plate 5 flashes, and the signal transmitter on the lifting scaffold sends an alarm signal to the signal receiver installed in the general contractor's office.

[0102] Example 9:

[0103] The main structure of this embodiment is the same as any one of embodiments 1 to 8. Furthermore, an electric winch is provided at the fixed position of the retractable steel wire rope 7 and the lifting scaffold.

[0104] Example 10:

[0105] The main structure of this embodiment is the same as any one of embodiments 1 to 9. Furthermore, a lifting method for an intelligent lifting system based on an attached lifting scaffold and an assembled unloading platform includes the following steps:

[0106] 1) Remove the load from the platform base plate 5;

[0107] 2) Remove the fixing pins 4 between the adjacent platform railings 3;

[0108] 3) Loosen the anchorage between the main beam 101 and the main structure I801, and push the main beam 101 back into the sleeve 102; the one-way check mechanism tightens due to the main beam retracting into the sleeve, causing the platform railing 3 to fall inward in one direction;

[0109] 4) Loosen the reinforcing steel wire rope 6 that is fixed to the main structure II802, and tie the reinforcing steel wire rope 6 to the lifting scaffold;

[0110] Start the electric winch to retract the retracting wire rope 7. The retracting wire rope 7 drives the platform base plate 5 to rotate, so that the platform base plate 5 is attached to the lifting scaffold.

[0111] 5) Lifting and raising the scaffolding;

[0112] 6) After the scaffolding is raised to the construction position, control the winch to release the platform base plate 5; then pull the main beam 101 out from the sleeve 102 and fix it to the structure (equivalent to the new main structure I801).

[0113] 7) Fix the reinforcing steel wire rope 6 to the structural floor (equivalent to the new main structure II802), and then fix the connection between the adjacent platform railings 3 with pins 4.

[0114] Example 11:

[0115] The main structure of this embodiment is the same as any one of embodiments 1 to 10, and further...

[0116] See Figure 3 a. Under operating conditions, reinforce the connection between the steel wire rope 6 and the structure.

[0117] See Figure 3 b. Under lifting conditions, reinforce the connection between the steel wire rope 6 and the lifting scaffold, and retract the steel wire rope 7 until the platform base plate 5 is tightly attached to the lifting scaffold.

[0118] See Figure 3 c. After being lifted to the designated position, the steel wire rope 6 is connected to the structure and the retractable steel wire rope 7 is lowered until the platform base plate 5 is vertically raised and lowered.

[0119] Example 12:

[0120] The main structure of this embodiment is the same as any one of embodiments 1 to 11. Furthermore, the main body of the system adopts a tool-type cantilever unloading platform assembled from standard modules, which mainly includes a telescopic cantilever pole, a folding unloading platform, and three steel wire ropes.

[0121] Furthermore, the retractable cantilever pole consists of a main beam and a sleeve for the main beam. The front end of the main beam is equipped with a press-type elastic self-locking mechanism, which can form a double fixation with the anchoring end of the main structure. The sleeve of the cantilever pole is equipped with a one-way check valve. After the main beam of the cantilever pole extends out of the sleeve, the valve pops out to fix the platform railing a second time.

[0122] Furthermore, the bottom of the folding unloading platform panel is made of 2mm thick patterned steel plate. The platform is surrounded by railings on three sides, also made of 2mm patterned steel plate, which are hinged to the base plate. The base plate's nesting rods protrude from the plate surface and are welded to the base plate, ensuring the railings can only be tilted inwards. The railings are secured with pins.

[0123] Furthermore, of the three steel wire ropes, two are reinforcing steel wire ropes and one is a contraction steel wire rope used during lifting operations. When the platform is in use, the two reinforcing steel wire ropes connect the platform to the structure. One of these ropes is equipped with a force gauge with a threshold. The platform has a weight limit of 800 kg. If the weight exceeds this limit, warning lights around the platform will illuminate the area, and an alarm signal will be sent to the general contractor's office via radio.

[0124] This invention also provides a construction method for using an assembled unloading platform on an attached lifting scaffold, the specific steps of which are as follows:

[0125] The first step is to clear the load from the platform in preparation for lifting. After the operators remove the connecting pins between the railings, no personnel will be allowed to enter the platform.

[0126] The second step is to loosen the anchorage between the main beam and the structure, push the main beam back, and the one-way check mechanism inside the sleeve will tighten due to the main beam contracting into the sleeve, causing the fence to fall inward in one direction due to the retraction of the mechanism.

[0127] Third, loosen the two reinforcing steel wire ropes fixed to the structure and tie them to the main pole of the climbing scaffold. Fix one retractable steel wire rope to the main pole of the climbing scaffold, and set up an electric winch at the fixed position to start retracting the platform, so that the platform is tightly attached to the climbing scaffold.

[0128] Fourth step: The platform retracts inward to fit tightly against the climbing frame, and the climbing frame begins to lift.

[0129] The fifth step involves lifting the climbing frame to the construction position, where the operator controls the winch to release the unloading platform, pulling the main beam out of the sleeve, and fixing and locking the main beam to the structure.

[0130] The sixth step is to fix the two reinforcing steel wire ropes to the floor structure after lifting, release the telescopic steel wire ropes, and fix the fence connection with pins. After the project management personnel accept the work, the platform lifting construction is completed.

[0131] Pushing the main beam back causes the one-way check valve inside the sleeve to tighten as the main beam retracts into the sleeve. The guardrail then collapses inward due to the retraction of the valve. The electric winch fixed to the main pole of the climbing frame is then started, and the wire rope pulls the platform toward one side of the climbing frame to reduce the lifting load and lower safety risks during the lifting process.

[0132] Example 13:

[0133] The main structure of this embodiment is the same as any one of embodiments 1 to 12. Furthermore, this invention provides an intelligent lifting system that can be assembled and deformed and is synchronously lifted with the attached lifting scaffolding. It has the advantages of convenience, speed, time saving, and no occupation of the tower crane. The structure is reliable, and the operating load and lifting load can be detected by sensors; it saves costs by using standardized components that are reusable. In projects where structures such as super high-rise core tubes require climbing scaffolding for construction, the lifting of the unloading platform will no longer occupy construction time.

[0134] Example 14:

[0135] The main structure of this embodiment is the same as any one of embodiments 1 to 13. Furthermore, this invention is applied to the construction of the main building structure of Phase III, Block B, Garden City International Resort Center.
