Life line anti-falling sliding block device

Abstract

The lifeline anti-falling sliding block device comprises a sliding block body, two lengthened bolts, a metal connecting rod and a clamping block, an opening groove is formed in the left end of the sliding block body, and a first welding plate and a second welding plate are horizontally welded to the upper end and the lower end of the opening groove respectively. The two lengthened bolts are screwed between the first welding plate and the second welding plate according to the thread principle, and a plurality of first mounting grooves are formed in the left side of the first welding plate. In order to solve the problems that in the prior art, due to the fact that a sliding block body is prone to fatigue fracture due to the fact that one side of the sliding block body bears large stress, the combined sliding block structure does not affect installation convenience of the sliding block at a steel wire rope, meanwhile, stress borne by the sliding block body can be dispersed to the two sides, the fatigue fracture phenomenon is not prone to occurring, and the service life of the sliding block is prolonged. And the safety is ensured.

Description

Technical Field

[0001] The utility model relates to a lifeline anti-falling sliding block device, belonging to the technical field of anti-falling in high-altitude operations. Background Art

[0002] The fall protection horizontal lifeline system is an anchoring device, which consists of an anchor bracket and a horizontal cable (mainly steel cable), the so-called horizontal lifeline, or safety line. This device, generally permanently fixed to a structure, is designed to ensure that one or more people can work safely at heights where a fall may occur, providing them with a freer space for activities. It can be installed in straight lines, curves, etc.

[0003] Publication No.: CN207871303U, mentions a standard slider for a lifeline fall prevention system. After the device rotates until the second limit block contacts the abutment block, the first limit block stops rotating and the second limit block continues to abut on the abutment block under the action of the elastic member, thereby closing the opening, improving the automation level of the standard slider and facilitating user use; in the process of the standard slider detaching from the wire rope, the user squeezes the first limit block and rotates it toward one side of the slider body to open the opening again, greatly improving the convenience of the user in separating the standard slider from the wire rope. However, due to its open design, the device can only connect the wire rope on one side when the slider body is suspended, which makes the slider body bear greater stress on one side, easily causing fatigue fracture, and safety cannot be guaranteed. Now there is an urgent need for a lifeline fall prevention slider device to solve the above-mentioned problems. Utility Model Content

This design solves the problem that due to its open design, the original device can only connect the wire rope on one side when the slider body is suspended, so that the slider body will be subjected to greater stress on one side, which is very prone to fatigue fracture.

[0019] As the first embodiment of the utility model: the lower end of the slider body 1 is integrally provided with a connecting portion 2, and the first welding plate 5 is fixed to the upper left end of the slider body 1 through a plurality of first reinforcing blocks 4. The first welding plate 5 is more firmly fixed to the upper left end of the slider body 1 through the addition of a plurality of first reinforcing blocks 4. The second welding plate 6 is fixed to the lower left end of the slider body 1 through a plurality of second reinforcing blocks 7. The second welding plate 6 is more firmly fixed to the lower left end of the slider body 1 through the addition of a plurality of second reinforcing blocks 7.

[0020] The left ends of the multiple metal snap-in pins 13 are all fixed with pull rings 14, and the added pull rings 14 facilitate the staff to manually pull out the metal snap-in pins 13. The multiple snap-in blocks 12 are respectively clamped in the multiple second installation grooves 16, and the right ends of the multiple metal snap-in pins 13 and the multiple strong magnet pieces 15 are inserted in the multiple positioning grooves.

[0021] As the second embodiment of the utility model: when the slider body 1 needs to be installed at the wire rope for use, the open groove 3 at the left end of the slider body 1 is aligned with the wire rope and clamped in, so that the wire rope can pass through the first welding plate 5 and the second welding plate 6 and enter the slider body 1, then the two extension bolts 17 are screwed so that the two extension bolts 17 are installed between the first welding plate 5 and the second welding plate 6 by threaded engagement, and then the multiple metal connecting rods 11 are swung counterclockwise (in this process, the multiple rings 10 rotate outside the multiple fixed shafts 9), so that the multiple clamping blocks 12 can be respectively clamped in the multiple second installation grooves 16, and then the multiple metal clamping pins 13 are pressed to the right, so that the right ends of the multiple metal clamping pins 13 and the multiple strong magnet pieces 15 are all inserted into the multiple positioning grooves. At this time, the multiple strong magnet pieces 15 can be fixed in the multiple positioning grooves by magnetic attraction of magnets, so that the two extension bolts 17 and the multiple metal connecting rods 11 can disperse the stress of the device suspended at the wire rope together with the right side of the slider body 1, so that it is not easy to cause fatigue fracture.
