Description

Technical Field

[0001] This application relates to the field of building technology, and in particular to a suspended platform for use on construction sites. Background Technology

[0002] In the construction industry, suspended platforms are an indispensable piece of equipment for high-altitude operations. With the booming development of urban construction, high-rise buildings are springing up everywhere, and the number of large commercial complexes and municipal infrastructure projects is surging, making the application scenarios of suspended platforms increasingly widespread and complex.

[0003] Traditional construction site suspended platforms typically rely on the connection and coordination of ropes and lifting equipment to achieve lifting operations. Existing suspended platform safety systems mostly focus on the structural strength design of the platform itself, resulting in relatively simple safety measures.

[0004] However, in certain special circumstances, such as when the rope suddenly breaks, the suspended platform may lose control and face the risk of falling. Existing suspended platforms have significant shortcomings in terms of buffering protection and secondary protection mechanisms in the event of sudden accidents. Once a fall occurs, the suspended platform's own structure alone is insufficient to effectively ensure personnel safety, easily leading to serious casualties and property damage. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a suspended platform for construction sites. Its advantages include: enabling the rapid deployment of airbags and protective mechanisms in emergency situations such as accidental breakage of the winding rope, effectively buffering the impact of the suspended platform falling, and improving the safety and reliability of suspended platform operations.

When the winding rope is disconnected, the auxiliary rope pulls the switch handle, causing it to rotate and activate the switch controller. The switch controller then activates the gas generator to inflate the airbag. Simultaneously, the rotation of the switch handle unlocks the protective mechanism via the locking mechanism, resulting in complete inflation of the airbag and full opening of the protective mechanism.

[0007] Preferably, the protective mechanism includes: two support plates, two mounting plates (first and second), two rotating shafts, and two connecting plates.

[0010] Compared with the prior art, the beneficial effects of this application are as follows:

[0011] (1) This utility model proposes a suspended platform for construction sites, which is equipped with a main body, mounting block, pulley assembly 1, mounting frame, drum, drive mechanism, winding rope, switch controller, auxiliary rope 1, airbag, gas generator, protective mechanism and pin mechanism. The suspended platform for construction sites drives the drum to wind the winding rope through the drive mechanism to achieve normal lifting and lowering operations. When the winding rope is broken, the auxiliary rope 1 is pulled to rotate the switch handle, triggering the switch controller to start the gas generator to inflate the airbag. At the same time, the protective mechanism is unlocked to open it. In case of emergency such as accidental breakage of the winding rope, the airbag and protective mechanism can be quickly opened to effectively buffer the impact of the main body of the suspended platform falling and improve the safety and reliability of the suspended platform operation.

Initially, the protective mechanism houses the airbag without hindering the lifting and lowering of the main body of the suspended platform. After the winding rope is disconnected, the auxiliary rope one pulls the switch handle to rotate, which drives the auxiliary rope two to move upward, thereby driving the pin rod to move upward and unlock the protective structure. Then, the mounting plate two moves under the thrust of the airbag inflation, the rotating shaft slides and drives the connecting plate to unfold, the mounting plate one rotates around the hinge point, and finally the protective mechanism is fully opened, providing protection and buffer for the main body of the suspended platform to fall accidentally.

[0024] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0025] One preferred embodiment of this application, such as Figures 1 to 8As shown, a suspended platform for construction sites includes: a main body 1, with support bases 21 fixedly installed at each of the four corners of the bottom of the main body 1; and also includes: mounting blocks 2, pulley assembly 3, mounting frame 4, drum 5, drive mechanism, winding rope 601, switch controller 7, auxiliary rope 602, airbag 10, gas generator 8, protective mechanism, and pin mechanism; there are two mounting blocks 2, which are fixedly installed at the center of the top two sides of the main body 1; there are two sets of pulley assembly 3, each including: a pulley and a mounting groove plate, the mounting groove plate being fixedly installed on one side of the top of the mounting block 2, and the pulley being rotatably installed on the mounting block 2. The inner walls at both ends of the trough plate; the mounting frame 4 is set directly above the main body 1 of the suspended platform; there are two drums 5, which are horizontally arranged, with one end of each drum 5 passing through both sides of one end of the mounting frame 4. The drums 5 are rotatably mounted to the mounting frame 4, and two winding grooves are opened on the circumference of the drums 5; the drive mechanism is installed at the other end of the mounting frame 4 to drive the two drums 5 to rotate and wind up; there are two sets of winding ropes 601, with one end of each set of winding ropes 601 fixedly installed on both sides of the bottom of the mounting frame 4, and the other end of the winding ropes 601 passing over the corresponding pulley assembly 3 and then winding up in one of the winding grooves of the corresponding drum 5; there are two switch controllers 7, two Each switch controller 7 is fixedly installed on the inner walls of both sides of the bottom of the suspended platform body 1; there are two switch handles 9, which are respectively hinged to the top of the housings of the two switch controllers 7 via damping pivots; there are two sets of auxiliary ropes 602, one end of which is installed on the top of the two switch handles 9 away from the damping pivot, and the other end of which is wound into the other winding slot of the corresponding drum 5; the airbag 10 is fixedly installed on the outer wall of the bottom of the suspended platform body 1; the gas generator 8 is located inside the airbag 10, and the gas generator 8 is electrically connected to both switch controllers 7; the protective mechanism is located at the bottom of the suspended platform body 1. The outer wall of the protective structure is used to store the airbag 10. There are two sets of locking mechanisms, which are respectively set on the top two sides of the protective structure to lock the protective structure. One end of the locking mechanism is fixedly installed with the switch handle 9. The winding rope 601 pulls the main body 1 of the basket to move up and down. After the winding rope 601 is disconnected, the auxiliary rope 602 is pulled by force to pull the switch handle 9. The switch handle 9 rotates to start the switch controller 7. The switch controller 7 starts the gas generator 8 to inflate the airbag 10. At the same time as the switch handle 9 rotates, it drives the locking mechanism to unlock the protective structure. The airbag 10 is fully inflated and the protective structure is fully opened.

[0026] First, the drive mechanism is activated, driving the two drums 5 to rotate. The two winding grooves on the circumference of the drums 5 begin to wind up the winding rope 601 and the auxiliary rope 602. The winding rope 601 pulls the main body of the suspended platform 1 to move it up and down along the building facade for normal vertical transportation and positioning operations. At this time, the auxiliary rope 602 is not under stress. When the winding rope 601 accidentally breaks, the gravity is transferred to the auxiliary rope 602. The auxiliary rope 602 pulls the switch handle 9, which rotates to trigger the switch controller 7, thereby activating the gas generator 8 and rapidly inflating the airbag 10. At the same time, the rotation of the switch handle 9 drives the pin mechanism to unlock the protective mechanism. The protective mechanism is fully opened under the push of the inflated airbag 10. This enables the rapid opening of the airbag and protective mechanism in emergency situations such as accidental breakage of the winding rope, effectively buffering the impact of the suspended platform falling and improving the safety and reliability of the suspended platform operation.

[0027] Further reference Figures 1-5 Hehe Figure 7 The protective mechanism includes: two support plates 11, two mounting plates 12, a second mounting plate 13, two rotating shafts 14, and two connecting plates 15. The two support plates 11 are fixedly installed on the outer walls of the bottom two sides of the main body 1 of the suspended platform. The two mounting plates 12 are hinged to the bottom of the two support plates 11. The second mounting plate 13 is located between the two mounting plates 12. The top of the two mounting plates 12 is provided with mounting grooves 22 on the side that is close to each other. The two connecting plates 15 are respectively located in the two mounting grooves 22. The inner walls of the two mounting grooves 23 are provided at both ends. The side of the two connecting plates 15 that is far from each other is hinged to the circumferential side of the two rotating shafts 14. The two ends of the rotating shafts 14 are slidably installed in the two mounting grooves 23. The other side of the two connecting plates 15 is hinged to the top two sides of the second mounting plate 13. The second mounting plate 13 and the two mounting plates 12 are provided with slots on adjacent sides. The second mounting plate 13 and the two mounting plates 12 are connected by the slots.

[0028] In the initial state, mounting plate 2 13 is tightly engaged with mounting plate 1 12 via a slot, and the rotating shaft 14 is in the initial position of mounting slot 2 23. The entire protective mechanism houses the airbag 10 without affecting the normal lifting and lowering operation of the suspended platform. When the winding rope 601 is accidentally disconnected, the auxiliary rope 1 602 is pulled by the force to rotate the switch handle 9. The rotation of the switch handle 9 drives the pin mechanism to unlock the protective mechanism, releasing the constraint of the slot connection between mounting plate 2 13 and mounting plate 1 12. Subsequently, mounting plate 2 13 begins to move under the outward thrust generated by the inflation of the airbag 10. The rotating shaft 14 slides and changes position in mounting slot 2 23, causing the connecting plate 15 to extend and unfold from mounting slot 1 22. Mounting plate 1 12 rotates outward around the hinge point with the support plate 11, forming a larger protective surface together with mounting plate 2 13 until the protective mechanism is fully opened, providing protection and buffer space for the suspended platform 1 in the event of an accidental fall.

[0029] Further reference Figure 8 The pin mechanism includes a pin rod 16, a pulley assembly 26, and an auxiliary rope 27. Pin holes 1 24 are provided on the inner walls of both sides of the bottom of the suspended platform body 1. Pin holes 25 are provided on the top sides of the two mounting plates 12 that are far apart from each other. Pin holes 1 24 and pin holes 25 are correspondingly arranged. The pulley assembly 26 includes a pulley and a mounting slot. The mounting slot is vertically fixed on the inner wall of the bottom of the suspended platform body 1 near the housing of the switch controller 7. The pulley is rotatably mounted on the inner walls of both sides of the mounting slot. The pin rod 16 is vertically arranged, with its bottom passing through pin holes 1 24 and 25. One end of the auxiliary rope 27 is fixedly connected to the top of the pin rod 16, and the other end is fixedly installed on the side of the auxiliary rope 602. The auxiliary rope 27 passes around the top of the pulley assembly 26.

[0030] In the initial state, the pin rod 16 tightly locks the mounting plate 12 and the main body of the suspended platform 1, keeping the protective mechanism stably in a retracted state, effectively enclosing the airbag 10, and ensuring that it will not interfere with the normal lifting and lowering operation of the suspended platform. When the winding rope 601 is accidentally disconnected, the auxiliary rope 602 is immediately stressed and pulls the switch handle 9, causing the switch handle 9 to rotate around the damping axis. The auxiliary rope 602 pulls the auxiliary rope 2 (27) upward, thereby driving the pin rod 16 to move synchronously, and then gradually pulling the pin rod 16 out of the pin hole 25, successfully releasing the locking restriction on the mounting plate 12 and the main body of the suspended platform 1, so that the protective mechanism can be smoothly deployed under the thrust generated by the subsequent inflation of the airbag 10, providing reliable protection and buffering for the suspended platform in dangerous situations.

[0031] Further reference Figure 2 , Figure 3 and Figure 6 The drive mechanism includes: a protective housing 17, a rotating motor 18, a hinge 19, and two gears 20. The protective housing 17 is fixedly installed on the other end of the mounting bracket 4. The rotating motor 18 is fixedly installed on the outer wall of one end of the protective housing 17. The two gears 20 are respectively fixedly installed on one end of the two drums 5. One of the gears 20 is fixedly installed on the output shaft of the rotating motor 18. The hinge 19 is meshed with both gears 20.

[0032] When performing the lifting operation, the rotary motor 18 is started, and its output shaft begins to rotate, driving the connected gear 20 to rotate synchronously. This causes another gear 20 to rotate as well. The two gears 20 drive the corresponding drums 5 to rotate, and the winding grooves on the circumference of the drums 5 begin to wind up the winding rope 601 and the auxiliary rope 602. As the winding rope 601 is continuously wound up, the suspended platform body 1 is pulled upward along the building facade, thus achieving the lifting operation. During the lowering operation, the rotary motor 18 reverses, and its output shaft drives the connected gear 20 to rotate in the opposite direction. The other gear 20 also rotates, and the two drums 5 reverse accordingly. The winding rope 601 is gradually released from the winding grooves of the drums 5, and the suspended platform body 1 slowly descends along the building facade under its own weight. Throughout the entire lifting process, the protective shell 17 effectively protects the rotary motor 18, gears 20, and hinges 19 from external interference and collision damage, ensuring the stable and reliable operation of the drive mechanism and guaranteeing the safety and smoothness of the suspended platform lifting operation.

[0033] Basic principle: During operation, the rotary motor 18 is started, and its output shaft begins to rotate, driving the gear 20 fixedly connected to it to rotate synchronously. Through the hinge 19, the other gear 20 also rotates. The two gears 20 respectively drive the corresponding drum 5 to rotate. The winding groove on the circumference of the drum 5 begins to wind up the rope 601. As the rope 601 is continuously wound up, the suspended platform body 1 experiences an upward pulling force, thus moving upward along the building facade, achieving the lifting operation of the suspended platform. To lower the suspended platform, the rotary motor 18 reverses, and its output shaft drives the connected gear 20 to rotate in the opposite direction, causing the other gear 20 to also rotate. As the rotation reverses, the two drums 5 also reverse. At this time, the winding rope 601 is gradually released from the winding groove of the drum 5, and the main body of the suspended platform 1 slowly descends along the exterior facade of the building, completing the descent operation. During this process, the protective shell 17 protects the rotating motor 18, gear 20, hinge 19, and other components from external environmental interference and collision damage, ensuring the stable and reliable operation of the drive mechanism and guaranteeing the safety and smoothness of the suspended platform's lifting and lowering operations. When the winding rope 601 accidentally breaks, the weight of the main body of the suspended platform 1, originally borne by the winding rope 601, is instantly transferred to the auxiliary rope 602. After being stressed, the auxiliary rope 602 begins to pull... The switch handle 9 is connected to the damping shaft and rotates around it. The rotation of the switch handle 9 triggers the switch controller 7. Upon receiving the signal, the switch controller 7 immediately starts the gas generator 8. After the gas generator 8 starts, a large amount of gas is rapidly generated inside the airbag 10, causing the airbag 10 to inflate. Simultaneously, auxiliary rope 1 602 pulls auxiliary rope 27 upwards, thereby causing the pin rod 16 to move synchronously. The pin rod 16 is pulled out from the pin hole 25, releasing the locking constraint on the mounting plate 1 12 and the main body of the suspended platform 1, allowing the protective mechanism to smoothly unfold under the subsequent inflation of the airbag 10. The mounting plate 2 13 is located within the airbag... The airbag 12 begins to move under the outward thrust generated by the inflation. The movement of the second mounting plate 13 transmits the force to the rotating shaft 14 through the connecting plate 15. The rotating shaft 14 begins to slide and change position in the second mounting groove 23, while simultaneously driving the connecting plate 15 to gradually extend and unfold from the first mounting groove 22. As the connecting plate 15 unfolds, the first mounting plate 12 rotates outward around the hinge point with the support plate 11, gradually forming a larger protective surface together with the second mounting plate 13 until the protective mechanism is fully opened. This enables the rapid deployment of the airbag and protective mechanism in emergency situations such as accidental breakage of the winding rope, effectively buffering the impact of the suspended platform falling and improving the safety and reliability of the suspended platform operation.
