[0002] In the wind power, construction, bridge and other industries, in order to ensure the construction safety of workers at heights, it is necessary to install highly reliable anti-fall facilities. The rail fall arrester is an important anti-fall device that connects the dangerous vertical surfaces in the industry and the construction workers. Through this device, construction workers can move freely and safely within a certain range along the direction of the T-rail.

[0003] The existing Chinese patent with the announcement number CN204337548U discloses a rail fall arrester for preventing falls during high-altitude operations. The rail fall arrester includes: a left guide block, a right guide block, an auxiliary guide rail, an anti-fall tongue, a tensioning spring, a tongue fixing pin, a guide block fixing pin, a guide block screw and an auxiliary guide rail screw.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the device needs to install the fall arrester on the T-rail from the notch at the bottom or top of the T-rail, so it is not very convenient to use and needs to be improved; therefore, a guide rail type high-altitude fall arrester is proposed to address the above problems.

The limit spring The other end of the spring 134 is fixedly installed inside the mounting groove 31, and the fastening lock hole 32 is opened at the inner side of the slide groove 15. When the fall arrester body 1 is installed on the rail 2, the spacing of the card plates 16 can be increased by the slidable card plates 16, which makes it easier for the fall arrester body 1 to be clamped on the guide rail for use. When the card plates 16 are against the rail 2, the insert block 33 is inserted into the fastening lock hole 32 by the elastic force of the limit spring 134, locking the card plates 16, so that the fall arrester body 1 is stably clamped on the rail 2 for use, and pushing the insert block 33 out of the fastening lock hole 32 can push the card plates 16 to slide and unfold, making it easy to disassemble the fall arrester body 1.

[0027] A slot 12 is provided at the center of the connecting body 11, and an anti-fall tongue 13 is connected to the inside of the slot 12 through an axial rotation. A tensioning spring 14 is fixedly connected to the surface of the anti-fall tongue 13, and the other end of the tensioning spring 14 is fixedly connected to the connecting body 11. The cross-sectional curve of the anti-fall tongue 13 adopts an involute cam structure. Under the tensioning action of the tensioning spring 14, the anti-fall tongue 13 is pre-tightened to the surface of the rail 2, ensuring that the anti-fall tongue 13 is pressed against the surface of the rail 2 under non-external force. When the wearer accidentally falls, the anti-fall tongue will rotate, so that the cam structure of the anti-fall tongue 13 is pressed against the rail 2 as it rotates and becomes tighter and tighter, forming a device that prevents falling by increasing friction.

[0028] The locking assembly 3 further includes an expansion lock opening 35 , which is provided on the outside of the slide groove 15 . By inserting the insert block 33 into the expansion lock opening 35 , the expanded state of the card plate 16 is locked, which is convenient for use.
