Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a falling prevention device for steel structure corridor construction. Background Art

[0002] During the construction of the steel structure corridor, construction workers need to climb with the help of a safety ladder. In order to avoid falling during the climbing process, a fall prevention device is installed on the top of the safety ladder to provide protection. According to the prior art, a new type of fall arrester described in Chinese patent document CN202020163637.3, the disclosed technical solution makes it safer and more reliable by setting the shell as a split structure. The hollow shaft of the shell part of the fall arrester can inject lubricating oil into the ratchet locking component to ensure the smooth rotation of the ratchet.

[0003] According to the technical solution disclosed by the developer, the fall arrester in the prior art directly installs the fall arrester on one side of the top of the safety ladder. When in use, the connecting buckle at the bottom of the fall arrester is pulled to connect with the safety buckle on the body, and then the fall arrester can be used. However, after the worker moves to the bottom to remove the connecting buckle, the safety rope will be retracted with the help of the recovery mechanism inside the fall arrester, which will cause shaking. The shaking phenomenon can easily cause the connecting buckle to collide with the safety ladder part and get hung during the recovery process, thus resulting in the phenomenon of failure to recover smoothly. On the other hand, after falling, even if the fall arrester is used to lock and pull within a very short distance, the short-term locking will cause a huge pulling sensation, and there is still a certain probability of causing strain at the rope connection.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4The utility model provides a technical solution: a fall prevention device for steel structure corridor construction, including a fall prevention device body, the fall prevention device body including a fall prevention device 1, a safety rope 2, an auxiliary bracket 3 and a guide buffer mechanism 4, the safety rope 2 is wound inside the fall prevention device 1, a shell 5 is provided on the surface of the fall prevention device 1, the safety rope 2 passes downward from the bottom of the shell 5, the auxiliary bracket 3 is installed on one side of the bottom of the shell 5, the guide buffer mechanism 4 is installed on the surface of the auxiliary bracket 3, the end of the safety rope 2 passes through the end of the guide buffer mechanism 4, the fall prevention device 1 is installed on one side of the top of the ladder, and the fall prevention device for steel structure corridor construction is installed. When installing, the fall arrester 1 is installed on one side of the top of the ladder, and the auxiliary bracket 3 is built along the ladder. When fixing, the fall arrester 1 body and the auxiliary bracket 3 are fixed respectively by the top fixing plate 6, the middle fixing plate 12 and the bottom fixing plate 16 to complete the installation. Finally, the bottom of the safety rope 2 is passed through the end of the guide buffer mechanism 4 to complete the construction. The fall arrester 1 is an existing mature technology, and the centrifugal locking mechanism inside can realize the automatic locking process when the safety rope 2 is pulled out quickly. The utility model uses a traditional fall arrester 1 to be installed on the side of the ladder, so the internal specific structure of the fall arrester 1 is no longer repeated.

[0024] In this embodiment, a top fixing plate 6 is provided at the rear end of the housing 5, a lifting rope 7 is connected to the top of the housing 5, a top connecting buckle 8 is connected to the top of the lifting rope 7, a bottom connecting buckle 9 is provided at the bottom of the safety rope 2, and a limit clamp 10 is installed on the safety rope 2 above the bottom connecting buckle 9, and a middle fixing plate 12 is provided at the bottom of the side of the housing 5, and the top fixing plate 6 and the middle fixing plate 12 are both fixed to the side of the ladder with bolts. The safety rope 2 is connected and guided by the auxiliary bracket 3 and the guide buffer mechanism 4, so after use, when the safety rope 2 is automatically recovered by the top fall arrester 1, the position of the bottom connecting buckle 9 can be limited at the end with the help of the guide buffer mechanism 4, so as to avoid the end of the safety rope 2 from swinging greatly during the recovery process, thereby avoiding the phenomenon of hanging on the ladder and causing recovery failure.

[0025] Specifically, after the bottom connecting buckle 9 is connected to the safety buckle on the user, the wearing can be completed, and the top of the fall arrester 1 shell 5 is snap-connected to the top of the ladder through the lifting rope 7 and the top connecting buckle 8, so it can also play a connecting role and achieve a backup connection effect.

[0026] In this embodiment, the auxiliary bracket 3 includes a spliced ​​vertical pole 13 and a bottom fixing plate 16, and the spliced ​​vertical pole 13 is provided in plurality, and a threaded column 14 is provided at one end of each spliced ​​vertical pole 13, and a threaded hole 15 is provided at the other end of the spliced ​​vertical pole 13. An end plate 11 is provided at the bottom of the middle fixing plate 12, and the bottom end of the end plate 11 is welded to the top spliced ​​vertical pole 13 as a whole, and the bottom fixing plate 16 is welded to the bottom spliced ​​vertical pole 13 as a whole, and each spliced ​​vertical pole 13 is constructed along the ladder on the side of the installation area.

[0027] Specifically, the auxiliary bracket 3 assembles each section of the spliced ​​upright pole 13 by cooperating with the threaded column 14 and the threaded hole 15, and the number of the spliced ​​upright poles 13 is selected according to the height of the specific construction range. During construction, the synchronous lifting sleeve 17 is directly sleeved on the surface of the spliced ​​upright pole 13. When the safety rope 2 connected to the top is subsequently used, the guide buffer mechanism 4 will be guided by the spliced ​​upright pole 13, thereby achieving the effect of guiding the end of the safety rope 2. When the use is completed and the safety rope 2 is recovered with the help of the inside of the fall arrester 1, the entire guide buffer mechanism 4 can be pulled up along the spliced ​​upright pole 13.

[0028] In this embodiment, the guide buffer mechanism 4 includes a synchronous lifting sleeve 17 and a guide rod 20. The synchronous lifting sleeve 17 is sleeved on the surface of the spliced ​​vertical pole 13. A side bracket 18 is installed on one side of the synchronous lifting sleeve 17. A rotating sleeve 19 is sleeved on the surface of the side bracket 18. The surface of the rotating sleeve 19 is connected to the guide rod 20. The top of the guide rod 20 is connected to a buffer spring 21. A tray 22 is installed at the end of the guide rod 20. A hole is opened inside the tray 22. The safety rope 2 passes through the hole in the center of the tray 22. The limit clamp 10 is arranged above the tray 22. The top of the buffer spring 21 is fixedly connected to the surface of the synchronous lifting sleeve 17. Through the guide rod 20 on the guide buffer mechanism 4 and the buffer spring 21 connected to the top, when a fall occurs, the bottom connecting buckle 9 and the wearer can be provided with a buffering effect by means of the stretching of the spring. By means of this buffering, the huge pulling feeling caused by the instantaneous locking of the safety rope 2 is reduced, thereby reducing the probability of strain after falling.

[0029] Specifically, when a fall occurs, the user leaves the ladder and pulls the safety rope 2 out quickly in a short period of time, thereby automatically triggering the locking structure inside the fall arrester 1, thereby realizing the locking process of the safety rope 2. When the safety rope 2 is locked and cannot be further extended, the fall arrester 1 and the falling person are not in the same vertical line, which causes the safety rope 2 to be pressed downward toward the position of the spliced ​​vertical pole 13, thereby causing the guide rod 20 to flip toward the bottom. At this time, the buffer spring 21 at the top can provide a downward buffering effect to the guide rod 20 and the limit clamp 10 at the end.

[0030] Since the end of the safety rope 2 is guided by the guide buffer mechanism 4, the user can keep a relatively close distance to the guide buffer mechanism 4 when wearing it, and the top part of the safety rope 2 will also be restricted by the tray 22 and will never go over the end of the tray, so that the safety rope 2 can avoid hindering the arm movement during the climbing process. Specifically, since the end limit clamp 10 pulls the safety rope 2 closer to the connection position on the user's body through the extension of the guide rod 20, it can avoid the upper safety rope 2 from being too close to the arm position, so that the arm part is not blocked during the subsequent climbing process.

[0031] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
