Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a construction platform for building engineering that is convenient for taking materials. Background Art

[0002] Construction platforms are temporary facilities used to assist workers in safe operations and facilitate the collection and unloading of materials. For example, patent CN118065650B describes a material unloading platform for convenient turnover in high-rise building construction. However, such platforms face two major safety hazards during material turnover operations.

[0003] First, when a platform adopts an external cantilever and internal fixed structure, when materials are stacked in the suspended area, a downward pressure torque is generated. Since the material stacking position is not fixed, this torque will change continuously with the movement of the cargo. Conventional counterweight methods that simply add fixed weights will not only fail to meet the dynamically changing torque balance requirements, but may also cause platform overload due to blindly adding counterweights, causing structural deformation or even total overturning accidents.

[0004] Secondly, during material transportation, if the movement speed is too fast or there is an abrupt stop and start, the inertia of the cargo will cause the stack to shift or even slide. Especially when the platform's movement direction suddenly changes, the impact force of the cargo may exceed the bearing capacity of the guardrails and cause serious harm to surrounding workers. The safety hazards brought about by this dynamic load require targeted control measures. Summary of the Invention

When the second lifting block 309 moves upward, the inner wall of the second lifting block 309 will slide in contact with the blocking block 308. When the hanging rail 306 is applied with an upward force, the hanging rail 306 will drive the supporting frame 302 to rise synchronously, so that the supporting frame 302 can be suspended inside the fixed frame 301.

It transmits torque through the magnetic action between a pair of magnetic devices (usually permanent magnets). When the magnet at the driving end rotates, it generates a changing magnetic field. This magnetic field acts on the magnet at the driven end through air or other media, causing the magnet at the driven end to rotate synchronously.

The friction block 512 is frictionally connected to the friction ring 509.

[0045] The working principle of the present invention is as follows:

[0046] First, when cargo needs to be transported to the interior of a building at a construction site, a crane will lift the cargo and move it to the interior of the load-bearing frame 302. Personnel need to stand inside the load-bearing frame 302 to perform construction (such as dismantling a fixing rope, carrying cargo, etc.). When the cargo is placed inside the load-bearing frame 302, the long plate 313 at the cargo placement position will be squeezed and bent by the cargo. The bent long plate 313 will squeeze the soft pad 312 and cause the pressure detection element provided inside the soft pad 312 to be pressurized and generate a corresponding electrical signal. The controller controls the linear drive device 305 to drive the moving block 307 to move to the corresponding bent soft pad 312. During the movement of the moving block 307, the clamping block 308, the second lifting block 309 and the limit frame 310 will be driven to move.

[0047] Secondly, when the goods placed inside the carrying frame 302 need to be moved into the building, first, the controller will determine the weight of the goods based on the electrical signal generated by the pressure detection element, and control the voltage input to the driving element, so that the driving element controls the reel to wind the lifting rope 411, so that the tightened lifting rope 411 is supported by the second support wheel 407, the support box 409 and the first support wheel 311 to lift the carrying frame 302 up inside the fixed frame 301 (the driving element controls the winding stroke of the reel to be proportional to the electrical signal generated by the pressure detection element). The controller then controls the voltage input to the second driving device 502 and the first driving device 403, so that the main shaft rotates to drive the connecting block 501 to drive the fixed frame 301 to move on the inner wall of the slide rail 1, so that the fixed frame 301 drives the carrying frame 30 2 moves toward the interior of the building, the first driving device 403 will drive the straight rail 405 to move synchronously with the connecting block 501 between the card plates 402 toward the interior of the building. The lifted load-bearing frame 302 can effectively reduce the weight applied to the fixed frame 301 and reduce the friction between the fixed frame 301 and the slide rail 1 during the movement toward the interior of the building. At the same time, when the goods are placed inside the load-bearing frame 302, the position of the lifting rope 411 when lifting the load-bearing frame 302 is driven to correspond to the position where the goods are placed. The torque generated when the lifting rope 411 lifts the load-bearing frame 302 corresponds to the downward torque generated by the weight of the goods inside the load-bearing frame 302. This can effectively prevent the load-bearing frame 302 from tilting or tipping over due to the weight of the goods inside the load-bearing frame 302 when the goods are moved after being placed.

[0048] Third, when the goods are driven to move into the interior of the building, the controller will control the voltage input to the rotating drive member according to the electrical signal generated by the pressure detection element, so that the output power of the rotating drive member can drive the slave shaft to rotate through the planar magnetic transmission coupling 508, and can drive the goods inside the carrying frame 302 to move into the interior of the building. During the rotation of the slave shaft, the bevel gear pair 513 is used to drive the linkage shaft 514 to rotate (the rotation speed of the slave shaft is equal to the rotation speed of the linkage shaft 514). When the linkage shaft 514 rotates, the pendulum rod 517 and the iron ball will generate centrifugal force. The centrifugal force generated drives the sliding ring 516 to slide upward on the outer wall of the linkage shaft 514 and compress the third spring 519. When the linkage shaft 514 slides upward, it will drive the lifting plate 520 to move and rise. The detection end of the displacement monitoring element 521 will rise synchronously with the lifting plate 520 and generate a corresponding electrical signal. The controller generates a corresponding electrical signal through the displacement monitoring element 521. The electrical signal controls the voltage input to the lifting drive 511, causing the output end of the lifting drive 511 to drive the friction block 512 downward to rub against the friction ring 509 (the friction between the friction block 512 and the friction ring 509 is less than the transmission torque of the planar magnetic transmission coupling 508. Therefore, when the friction block 512 rubs against the friction ring 509, the rotation speed of the main shaft can only be reduced. Similarly, the controller controls the voltage input to the lifting drive 511 through the electrical signal generated by the displacement monitoring element 521 to adjust the voltage, so as to prevent the lifting drive 511 from driving the friction block 512 downward to rub against the friction ring 509, causing the main shaft to be completely unable to rotate). In this way, the rotation speed of the main shaft is reduced. When the main shaft slows down, the moving speed of the carrying frame 302 and the cargo will also be slowed down synchronously. This can effectively prevent the cargo from being transported into the building at an excessively high speed, causing the cargo to move significantly into the building due to inertia, causing personal injury or cargo scattering, making it inconvenient for construction personnel to carry it.

[0049] It should be noted that when transporting lighter goods, the pressure detection element will generate a corresponding electrical signal according to the weight of the goods, and the controller controls the input voltage to the rotating drive member according to the weight of the goods, so that the driving power of the rotating drive member is proportional to the weight of the lighter goods. At the same time, the driving power of the rotating drive member drives the slave shaft and the main shaft to rotate so that the moving speed of the fixed frame 301, the carrying frame 302 and the goods is proportional. In general, because the weight of the goods is light, even when it is driven to move at a certain moving speed, the inertia generated will be relatively small, so the electrical signal generated by the pressure detection element is weak. The controller controls the voltage input to the rotary drive member to be relatively small, and the output power of the rotary drive member is relatively small. Therefore, lighter goods will not be transported at a faster speed. In the process of driving the slave shaft to rotate, the rotary drive member also drives the linkage shaft 514 to rotate at a slower speed (the linkage shaft 514 is proportional to the rotation speed of the slave shaft). The swing amplitude of the pendulum rod 517 and the iron ball due to centrifugal force is relatively small, and the lifting plate 520 will not be lifted. Correspondingly, the friction between the friction block 512 and the friction ring 509 will also be reduced accordingly (without affecting the rotation speed of the friction ring 509 and the main shaft).

[0050] When transporting heavier goods, the pressure detection element will generate a larger electric signal according to the weight of the goods. The controller controls the input voltage of the rotary drive member through the generated electric signal, so that the driving power of the rotary drive member is proportional to the weight of the heavier goods. At the same time, the driving power of the rotary drive member causes the slave shaft and the main shaft to rotate to make the moving speed of the fixed frame 301, the carrying frame 302 and the goods proportional. In general, because the weight of the goods is heavier, when the rotary drive member is controlled to drive the heavier goods to move at a normal speed, the goods will generate a larger inertial force. Therefore, during the rotation of the slave shaft, the cone The gear pair 513 drives the linkage shaft 514 to rotate at the same speed, causing the swing arm 517 and the iron ball to swing more widely, causing the sliding collar 516 and the lifting plate 520 to rise more widely, and causing the displacement monitoring element 521 to generate an electrical signal corresponding to the lifting range of the lifting plate 520. Correspondingly, the friction between the friction block 512 and the friction collar 509 is also increased accordingly, causing the rotation speed of the main shaft and the friction collar 509 to be further slowed down on the basis of the normal driving of the fixed frame 301, the carrying frame 302 and the cargo to move, allowing heavier cargo to be moved into the building at a slower speed.

[0051] The beneficial effects of slowing down heavier cargo are as follows:

[0052] 1. Directly adjusting the power of rotating drive components requires a precise closed-loop control system (construction environments are relatively simple, and most installations are portable). However, interference factors such as vibration and sudden load changes in construction environments can cause control delays or overshoot. By combining the centrifugal force of the slave shaft drive pendulum 517 and the iron ball with friction braking (mechanical method), physical braking can be triggered immediately when the speed is abnormal, quickly offsetting inertia and preventing cargo slippage or impact caused by delayed electronic system response.

[0053] 2. Frequent adjustments to the power of the rotating drive components can lead to energy waste and overheating, especially during heavy-load or high-frequency operations. Friction braking can disperse impact energy and prevent drastic load fluctuations on the rotating drive components, thereby improving system stability. In addition, the braking system can flexibly adjust the speed of the rotating drive components while maintaining a constant power output, reducing control complexity.

[0054] 3. Construction platforms often need to cope with dynamic loads such as uneven cargo distribution and instantaneous impact. Direct reliance on rotating drive components for speed control requires extremely high sensor accuracy and algorithm adaptability. Mechanical braking, on the other hand, directly links centrifugal force and inertial force (the centrifugal displacement of the iron ball in the pendulum 517 triggers the friction block 512), which can more intuitively reflect actual working conditions, reduce reliance on electronic systems, and enhance environmental adaptability.

[0055] Furthermore, through the provision of the top rod 505, when the fixed frame 301 moves toward the interior of the building, the fixed frame 301 will contact the top rod 505, so that the top rod 505 drives the piston plate 504 to compress the second spring 506. The provision of the second spring 506 can effectively slow down the movement speed of the fixed frame 301 to prevent the cargo from moving inside the supporting frame 302.
