[0037] Working principle:

[0038] After the device is installed, the first fixture 1 and the second fixture 2 are in a combined state and are respectively clamped on the left and right sides of the lower wing plate of the I-beam in the roof steel frame (such as Figure 6As shown), and the buckle 3 and the U-shaped slot 4 are in a clamping state. When it is necessary to remove, the staff stands on the bottom surface of the roof and first slightly pulls down the handle bar 10 to separate the block 19 from the first limiting slot 17, and then rotates the handle bar 10 until the block 19 is aligned with the second slide slot 18, and then pushes the handle bar 10 upward (at this time, the block 19 slides up along the block 19), the handle bar 10 drives the lifting rod 6 to slide up, the lifting rod 6 drives the slider 8 and the push rod 9 to slide up, the slider 8 causes the second sleeve 14 and the second slide rod 15 to gradually contract, and the spring 16 gradually changes from a tension state to a compression state, until the push rod 9 is pushed up to the buckle 3 and the U-shaped slot 4 are separated, and the second sleeve 14 is aligned with the second The slide bar 15 stretches under the elastic force of the spring 16, so that the first fixture 1 slides away from the second fixture 2 until the first fixture 1 and the second fixture 2 are completely separated. After the first fixture 1 and the second fixture 2 are separated, the spacing between the upper openings of the first fixture 1 and the second fixture 2 is sufficient to exceed the width of the lower wing plate of the I-beam in the roof steel frame. At this time, the block 19 just slides up to the top of the second slide groove 18 and is aligned with the second limiting groove 20. Then, by appropriate rotation, the block 19 is inserted into the second limiting groove 20 to prevent the handle bar 10 from bouncing down under the elastic force of the spring 16. Finally, the separated first fixture 1 and the second fixture 2 are removed from the lower wing plate of the I-beam.

[0039] When installing the device, the worker stands on the bottom surface of the roof and clamps the second fixture 2 on the right side of the lower wing plate of the I-beam by holding the handle rod 10, and then pulls down the lifting rod 6 through the handle rod 10. The lifting rod 6 drives the slider 8 to slide down, and the slider 8 stretches the elastic telescopic mechanism, so that the spring 16 gradually changes from a compressed state to a stretched state. The first fixture 1 slides toward the second fixture 2 under the pulling force of the spring 16 until the first fixture 1 and the second fixture 2 are combined and clamped on the left side of the lower wing plate of the I-beam. When the first fixture 1 and the second fixture 2 are completely combined, the buckle 3 is just connected with the U-shaped slot 4, thereby realizing the The installation of the device, after installation, can be hung with a safety rope at the hanging hole 25 at the end of the cross bar 24; when the buckle 3 is just connected with the U-shaped slot 4, the upper end of the block 19 is just lower than the lower end of the vertical pipe 5 as the handle bar 10 moves downward. At this time, the handle bar 10 is rotated until the block 19 is aligned with the first limiting groove 17, and then the handle bar 10 is released. The handle bar 10 slides up under the pulling force of the spring 16 in the stretched state, and the block 19 is inserted into the first limiting groove 17, so that the handle bar 10 can no longer slide up, thereby preventing the handle bar 10 from colliding with the external connection to open the first fixture 1 and the second fixture 2.

[0040] To sum up, the installation and disassembly of the device is simple and fast. The staff only needs to pull down or push up the handle rod 10 on the bottom surface to complete the installation or disassembly of the device on the lower wing plate of the I-beam at a high position in the roof steel frame. There is no need to slowly screw in screws, which greatly improves the construction efficiency. There is no need for the staff to climb up and down with tools, which avoids working at heights, thereby reducing construction costs and improving the safety of installation and disassembly operations. After the device is installed, the tension of the elastic telescopic mechanism in a stretched state can be used to make the block 19 stuck in the first limit groove 17, so that the handle rod 10 is relatively fixed, thereby avoiding the handle rod 10 from colliding with the first clamp 1 and the second clamp 2 due to external collision, further improving the safety and reliability of the device.

[0041] The technical features disclosed above are not limited to the disclosed combinations with other features. Those skilled in the art may also make other combinations between the technical features according to the purpose of the utility model to achieve the purpose of the utility model.
