Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit or scope of the invention, which is therefore not limited to the specific embodiments disclosed below.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 4, the anti-falling device for a high-voltage transmission line iron tower in the present embodiment includes an iron tower, a climbing frame 2, a differential self-locking device 3, a safety rope 4 and a fixing device 5.
The iron tower comprises a tower body 1, wherein the tower body 1 is almost in a vertical shape and mainly plays a role in supporting a wire cross arm of the iron tower. Through a great deal of work, it was found that workers mainly fall from the tower body 1 during the climbing process, and thus it was necessary to ensure the safety of the workers during the climbing process of the tower body 1.
The climbing frame 2 is used as a main tool for the overhauling personnel to climb the iron tower. The climbing frame 2 is fixedly arranged on the tower body 1 of the iron tower from bottom to top, and workers climb to the upper end of the iron tower from the climbing frame 2 during maintenance, and then overhaul the iron tower. The climbing frame 2 is a general tool on the pylon and will not be described in detail here.
The differential self-locking device 3 comprises a fixed end and a using end, wherein the fixed end is fixed at the top end of the climbing frame 2 or the top end of the tower body 1. The main function of the differential self-lock 3 is that it can act to limit the falling speed of the safety rope 4 when the safety rope 4 falls. The differential lock 3 is a common tool and will not be described in detail here. Specifically, the fixed end of the differential self-locking device 3 is a hook 6, a hanging hole 7 is correspondingly formed in the top end of the climbing frame 2 or the tower body 1, and the hook 6 is hung into the hanging hole 7 to realize connection and fixation of the two.
And one end of the safety rope 4 is connected with the using end of the differential self-locking device 3, and the other end of the safety rope 4 is detachably connected to the lower part of the tower body 1 through a fixing device 5. The safety line 4 has a suspension loop 41 at the end near the securing means 5.
Typically, the safety line 4 is secured to the lower part of the tower 1 by means of a securing device 5. When the iron tower is required to be overhauled, an overhauling personnel stands at the bottom of the iron tower, wears the safety belt, and removes the fixing device 5, removes the safety rope 4 and connects with the safety belt (the hanging hook 6 of the safety belt is connected with the hanging ring 41 on the safety rope 4 to be fixed), then the overhauling personnel climbs onto the iron tower along with the climbing frame 2, the safety rope 4 is gradually retracted into the differential self-locking device 3 in the upward climbing process, when the overhauling personnel accidentally falls, the safety rope 4 is driven to fall down, when the differential self-locking device 3 detects that the falling speed of the safety rope 4 exceeds a set value, the safety rope 4 is locked to prevent the falling of the overhauling personnel, so that the safety of the overhauling personnel is ensured.
After the overhauling personnel is finished, the overhauling personnel gradually stretches the safety rope 4 in the downward moving process along with the climbing frame 2, and when the overhauling personnel moves down to the bottom of the tower body 1, the safety rope 4 is separated from the safety belt, and the safety rope 4 is fixed on the tower body 1 through the fixing device 5 so as to be used next time.
The fixing device 5 is mainly used for fixing the safety rope 4. The safety rope fixing device comprises a cover plate 51 and a cover body 52, wherein the cover body 52 is fixedly connected to the tower body 1, a through hole 53 suitable for accommodating the safety rope 4 is formed in the cover plate 51, and the diameter of a hanging ring 41 on the safety rope 4 is larger than that of the through hole 53, so that the safety rope 4 cannot be separated from the fixing device 5 after being fixed in the through hole 53. The cover plate 51 is fixed to the cover body 52 by bolts 54. Specifically, two bolts 54 are provided, screw holes are provided in the cover plate 51 and the cover body 52 on both sides of the via hole 53, and the bolts 54 are screwed into the screw holes to fix the cover plate 51 to the cover body 52.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
