[0017] In the present invention, the main cable is locked by the locking assembly when the construction platform fails and falls rapidly.

In this process, the trigger rod contacts the trapezoidal guide block and rotates 90° under the action of the trapezoidal guide block, so that the auxiliary anti-fall rod at the bottom of the trigger rod contacts the anti-fall convex strip, thereby sharing the force of the main cable and avoiding the main cable from being subjected to excessive instantaneous force and causing secondary breakage.

[0018] In the present invention, when the locking component is triggered, the anti-fall component is also triggered synchronously. The Z-bar in the anti-fall component rotates around the connecting shaft, driving the horizontal anti-fall bar to contact the anti-fall convex strip, and the construction platform is instantly locked to prevent the construction platform from falling from a height and injuring the workers in the riding cavity.

[0019] In the present invention, when the anti-fall component is triggered, the main beam is also pushed down synchronously. During this process, the main beam moves the guardrail downward to block the front and rear exits of the riding chamber, thereby preventing workers from losing balance and falling from the construction platform and getting injured due to vibration during the falling process of the construction platform. At the same time, the downward movement of the guardrail will also squeeze the semi-circular rod downward, causing the semi-circular rod to move toward the inside of the riding chamber, thereby lifting the lifting plate and increasing the distance between the lifting plate and the bottom of the riding chamber, thereby increasing the buffer distance and reducing the degree of injury to workers when falling.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

Under normal working conditions, the two sets of winches rotate at the same speed. When the construction platform 2 fails and falls rapidly, the top plate 8 is connected to the winch through the secondary cable 9, the relative speed between the top plate 8 and the construction platform 2 changes, and the top plate 8 moves up relative to the construction platform 2. This is the prior art and will not be elaborated here.

[0032] In this embodiment, Figure 3 , Figure 4 , Figure 8 and Fig. 9As shown, the locking assembly 3 includes an arc-shaped leaf spring 3012 fixedly connected to the inside of the installation cavity 202, and the top surface of the arc-shaped leaf spring 3012 is integrally formed with four groups of installation blocks 301, and a horizontal shaft 302 is fixedly connected between two installation blocks 301 in each group, and the horizontal shaft 302 passes through the middle of the arc-shaped notch 303, and the arc-shaped notch 303 is provided at the bottom of the outer driving block 304, and a vertical limiting groove 305 is provided in the middle of the outer driving block 304, and a horizontal limiting rod 306 passes through the middle of the vertical limiting groove 305, and a locking block 307 is slidably attached to the side of the outer driving block 304 close to the main cable 10, and the top of the locking block 307 extends to the top of the installation cavity 202. The outer side of the part is connected to the T-block 308, and the side of the T-block 308 away from the main cable 10 is fixedly connected with a horizontal connecting plate 309, and the middle part of the end of the horizontal connecting plate 309 away from the T-block 308 is rotatably connected to a trigger rod 3010, and the bottom end of the trigger rod 3010 is integrally formed with an auxiliary anti-fall rod 3011. The upper half of the outer drive block 304 is an inverted right-angled trapezoid, and the locking block 307 is an upright right-angled trapezoid. The side where the outer drive block 304 and the locking block 307 are in contact is the side where the hypotenuse of the right-angled trapezoid is located; the two ends of the horizontal limit rod 306 are fixedly connected to the front and rear inner walls of the installation cavity 202. When the construction platform 2 is raised or lowered, the arc plate is pulled by the main cable 10. The spring 3012 drives the construction platform 2 to rise. At this time, the arc leaf spring 3012 will be deformed by the tension, so that the arc leaf spring 3012 is in a contracted state. At this time, the arc leaf spring 3012 pushes the outer drive block 304 upward. The outer drive block 304 always maintains vertical movement under the cooperation of the vertical limit groove 305 and the horizontal limit rod 306. Moreover, since the hypotenuse of the outer drive block 304 is in contact with the hypotenuse of the locking block 307, when the outer drive block 304 moves up, the locking block 307 will not be squeezed by the outer drive block 304, that is, the locking block 307 will not lock the main cable 10. On the contrary, when a fault occurs, the construction platform 2 falls and the arc leaf spring 3012 pushes the outer drive block 304 upward. The spring 3012 loses its upward pulling force and resets under its own rebound action. The arc leaf spring 3012 cooperates with the mounting block 301, the horizontal shaft 302 and the arc groove 303 to drive the outer driving block 304 to move downward. At this time, the outer driving block 304 will squeeze the locking block 307 in the direction close to the main cable 10 through the oblique edge, so that the locking block 307 locks the main cable 10, and the locking block 307 will also drive the top T-block 308 to move synchronously in the process of approaching the main cable 10. The T-block 308 will drive the trigger rod 3010 to approach the main cable 10 through the horizontal connecting plate 309, and the trigger rod 3010 contacts and rotates with the trapezoidal guide block 802.

[0033] In this embodiment, Figure 8 and Fig. 9As shown, the T-block 308 is slidably arranged inside the movable slide groove 801, the movable slide groove 801 is opened on the bottom surface of the top plate 8, and a trapezoidal guide block 802 is integrally formed between the inner walls of the movable slide groove 801, the trigger rod 3010 is composed of a trigger section 3010a, a horizontal section 3010b and a rotating section 3010c, the top surface height of the horizontal section 3010b is lower than the bottom surface height of the trapezoidal guide block 802, the rotating section 3010c runs through the middle of the horizontal connecting plate 309, and the rotating section 3010c and the horizontal connecting plate 309 are interference fit through the bearing; when the trigger rod 3010 moves toward the main cable 10, the trigger section 3010a of the trigger rod 3010 will move along The trigger rod 3010 moves along the hypotenuse of the trapezoidal guide block 802. At this time, the trigger rod 3010 will rotate with the rotating section 3010c as the axis. When the locking block 307 locks the main cable 10, the trigger rod 3010 completes a 90° rotation, so that the auxiliary anti-fall rod 3011 at the bottom end of the trigger rod 3010 extends to the outside of the top plate 8, and the end of the auxiliary anti-fall rod 3011 away from the trigger rod 3010 will intersect with the anti-fall convex strip 6 in a top view. This structure can lock the main cable 10 when the construction platform 2 suddenly falls, and at the same time, the auxiliary anti-fall rod 3011 extends into the anti-fall convex strip 6, so that the anti-fall convex strip 6 blocks the auxiliary anti-fall rod 3011 to prevent the construction platform 2 from continuing to fall.

[0034] In this embodiment, Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the anti-fall component 4 includes two mounting plates 402 integrally formed in the middle of the bottom surface of the arc-shaped leaf spring 3012, a fixed shaft 403 is fixedly connected between the two mounting plates 402, the fixed shaft 403 movably passes through the middle of the straight slot 404, the straight slot 404 is arranged in the middle of one end of the Z-shaped rod 405, a connecting shaft 406 passes through the middle of the Z-shaped rod 405, both ends of the connecting shaft 406 are fixedly connected with vertical strip plates 407, the bottom end of the vertical strip plates 407 is connected to the inner bottom surface of the mounting cavity 202, the Z-shaped rod 405 extends from one end of the arc-shaped leaf spring 3012 to the outside of the mounting cavity 202 and is integrally formed with a horizontal anti-fall rod 408; when the arc-shaped leaf spring 3012 loses the tension from the main cable 10, the arc-shaped leaf spring 3012 rebounds downward, thereby The mounting plate 402, the fixed shaft 403 and the straight slot 404 cooperate to drive one end of the Z-shaped rod 405 to move downward. At this time, the Z-shaped rod 405 rotates around the connecting shaft 406, and the other end of the Z-shaped rod 405 moves upward in the counterclockwise direction, driving the horizontal anti-fall rod 408 to move synchronously. The horizontal anti-fall rod 408 also revolves around the connecting shaft 406 during movement. During this process, the horizontal anti-fall rod 408 will gradually approach the anti-fall convex strip 6 and finally contact the anti-fall convex strip 6. Because the cross-section of the anti-fall convex strip 6 is a triangle, and the right-angled side of the triangle is on the top, therefore, during the falling process of the construction platform 2, the anti-fall convex strip 6 can block the horizontal anti-fall rod 408 to prevent the construction platform 2 from falling, and jam the construction platform 2, thereby avoiding the falling of the construction platform 2 and causing casualties of the internal staff.

[0035] In this embodiment, Figure 7 and Figure 8 As shown, the mounting plates 402 are grouped in pairs, for a total of three groups, and the three groups of mounting plates 402 are all connected by the main beam 409, and the inner bottom surface of the mounting cavity 202 is located directly below the main beam 409 to form an integrally formed limited position rectangular block 401; the limited position rectangular block 401 can block the main beam 409, and this structure is used to limit the rotation angle of the Z-shaped rod 405, because once the Z-shaped rod 405 rotates too much, it will be separated from the anti-fall protrusion 6 and will not be able to play an anti-fall role.

[0036] In this embodiment, Figure 5As shown, the protection component 5 includes a guardrail 501 fixedly connected to both ends of the main beam 409, the bottom surface of the guardrail 501 is integrally formed with a rectangular frame 502, the bottom surface of the rectangular frame 502 is fixedly connected with a lifting side plate 503, the lifting side plate 503 is located just above the semi-circular rod 504, the semi-circular rod 504 movably penetrates the bottom edge of the riding chamber 201, and the semi-circular rod 504 extends to one end of the riding chamber 201 and is integrally formed with a lifting rod 505; when the arc leaf spring 3012 rebounds, it will drive the main beam 409 to move downward. In this process, the two main beams 409 located on the outermost side will synchronously drive the guardrail 501 connected thereto to move downward, and the downward movement of the guardrail 501 will bring The movable rectangular frame 502 slides downward along the outer shell of the construction platform 2, and the rectangular frame 502 pushes the connected lifting side panel 503 to move downward. The downward movement of the guardrail 501 can prevent workers from falling from the front and rear openings due to shaking during the falling process of the construction platform 2. The front and rear openings are reduced to a size less than that of one person by lowering the guardrail 501 to prevent workers from falling from the construction platform 2. When the lifting side panel 503 descends, it will contact the semi-annular rod 504. During this process, the part of the semi-annular rod 504 located outside the riding chamber 201 is squeezed by the lifting side panel 503 and moves toward the inside of the riding chamber 201, and the semi-annular rod 504 pushes the lifting rod 505 to move upward.

[0037] In this embodiment, Figure 5 As shown, a lifting plate 203 is movably connected to the inner bottom of the riding chamber 201, and the bottom surface of the lifting plate 203 is in contact with the top surface of the lifting rod 505. Sliding plates 204 are integrally formed on the outer side edges of the riding chamber 201. The sliding plate 204 is slidably arranged in the gap between the anti-fall convex strip 6 and the limiting vertical plate 7 on the side away from the riding chamber 201. When the lifting rod 505 moves upward, the lifting plate 203 in contact with it is lifted upward, so that the lifting plate 203 is separated from the bottom plate of the riding chamber 201. This structure can increase the gap between the lifting plate 203 and the bottom plate of the riding chamber 201 to increase the buffer distance, thereby reducing the degree of injury to the workers in the construction platform 2.

[0038] The use method and advantages of the present invention: When the safety anti-falling device for building construction is used, the working process is as follows:

[0039] When the construction platform 2 falls rapidly due to a fault, the locking component 3 is triggered, and at the moment of locking the main cable 10, the auxiliary anti-fall rod 3011 is synchronously driven to extend and engage with the anti-fall convex strip 6, thereby dispersing a part of the force of the construction platform 2 falling to the auxiliary anti-fall rod 3011 and the anti-fall convex strip 6. In addition, when the locking component 3 is triggered, the anti-fall component 4 and the protective component 5 are also driven to move, so that the horizontal anti-fall rod 408 in the anti-fall component 4 is engaged in the middle of the anti-fall convex strip 6, and the construction platform 2 is emergency braked. The movement of the protective component 5 will first drive the guardrail 501 to descend, and protect the workers inside the seating chamber 201, so as to prevent the workers from falling from the seating chamber 201 due to vibration during the rapid falling of the construction platform 2. In addition, the descent of the lifting side plate 503 in the protective component 5 will trigger the semi-annular rod 504 to lift the lifting plate 203, thereby increasing the buffer distance between the lifting plate 203 and the bottom plate of the construction platform 2, thereby reducing the degree of injury to the workers in the construction platform 2.
