[0020] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in further detail below in conjunction with the drawings.

[0021] Referring to Figures 1 to 3 The utility model discloses an anti-falling structure of a suspension platform, which comprises a platform main body 1, a safety lock 2, a safety rope 3 and a working rope 4.

[0022] This utility model embodiment improves the structure and setting method of the safety lock, enabling it to react quickly to the breakage of the working rope, and the structure is simple.

[0023] Specifically, the platform body 1 is provided with safety locks 2 on both sides. One end of the working rope 4 is connected to the winch of the suspended platform, and the other end is pulled from the outer surface of the winch through the abutting rollers 28 of the safety locks 2 on both sides and then reversed to connect with the winch. The safety rope 3 is provided on both sides of the platform body 1, and the end of the safety rope 3 passes through the safety lock 2.

[0024] The safety lock 2 has a first rotating shaft 21 and a second rotating shaft 22 inside. Both the first rotating shaft 21 and the second rotating shaft 22 have swing arms 23 on their sides. A torsion spring is provided between the two swing arms 23. A locking sleeve 24 is hinged on the swing arm 23. The safety lock 2 has a pressing part 25 above the locking sleeve 24 inside. Both ends of the first rotating shaft 21 extend to the outside of the safety lock 2 and are equipped with locking support plates 27. The end of the locking support plate 27 is provided with an abutting roller 28, which abuts against the working rope 4.

[0025] This invention uses the working rope 4 to continuously press the abutment roller 28 on the safety lock 2, causing the locking support plate 27 to be pressed downwards towards the suspended platform, thus ensuring that the safety lock 2 is not locked to the safety rope 3. When the working rope 4 breaks, the first pivot 21 and the second pivot 22 of the safety lock 2 swing upwards under the action of the torsion spring, while the locking support plate 27 rebounds, and the locking sleeve 24 inserts into the compression part 25 to lock the safety rope 3. This invention has a simple structure, can react quickly to the breakage of the working rope 4, and has a strong fall prevention effect.

[0026] Preferably, the top of the compression part 25 is provided with a compression groove 26, and the cross-sectional area of ​​both the compression groove 26 and the locking sleeve 24 gradually decreases from the bottom to the top. The compression groove 26 and the locking sleeve 24 compress against each other, triggering the locking structure of the locking sleeve 24 on the safety rope 3.

[0027] Preferably, the locking sleeve 24 has at least two steel balls 241 evenly spaced inside, and the outer surface of the locking sleeve 24 has a slot 242 adapted to the steel balls 241. After the locking sleeve 24 is locked, the steel balls 241 contact and compress the safety rope 3, thereby preventing the safety rope 3 from continuing to move upward. This can lock the safety rope 3 in time, preventing the suspended platform from falling. Furthermore, as the tension of the safety rope 3 increases, the compressive force of the steel balls 241 on the safety rope 3 will also increase, thus effectively reducing the locking distance and improving safety when the tension of the safety rope is too high.

[0028] Ideally, the contact surface between the locking sleeve 24 and the steel ball 241 is an inclined surface structure 243 that slopes outward from the center. Due to the inclined surface structure 243, when the locking sleeve 24 is in the unlocked state, the steel ball 241 will roll along the inclined surface and move away from the surface of the safety rope 3.

[0029] Ideally, the angle between the inclined plane structure 241 and the horizontal plane is 10-15°.

[0030] Preferably, the locking support plate 27 has arc-shaped grooves 271 on both sides, and the outer surface of the safety lock 2 has a limiting post, which is located in the arc-shaped groove 271.

[0031] More preferably, one side of the locking support plate 27 is provided with an extension plate 272 integrally formed therewith, and the locking support plate 27 and the extension plate 272 are provided with a plurality of roller connection holes 273 arranged at equal intervals along a straight line. By providing the extension plate 272 and providing a plurality of roller connection holes 273 arranged in a straight line on the locking support plate 27 and the extension plate 272, the angle adjustment range of the locking support plate 27 is widened.

[0032] Accordingly, this utility model embodiment also provides a suspension platform, including the aforementioned anti-fall structure.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
