Abstract
The utility model discloses an anti-falling chain. The anti-falling chain consists of a safety bumping block (4) and is characterized in that two sides of a roadway above the safety bumping block (4) are fixedly connected with round steel (1); the inner side of the round steel (1) is fixedly connected with hooks (3); and two ends of each iron chain (2) are movably connected with the hooks (3). Therefore, the anti-falling chain has a simple structure, is convenient to use, can effectively prevent staff from falling into a shaft, and is particularly suitable for drop shaft operation of staff under a mine shaft.
Description
Technical field:
The utility model relates to a kind of anti-fall chain, and down-hole, particularly a kind of mine is with the anti-fall chain of drop shaft.
Background technology:
In bargh; Because popularizing of down-hole mechanicalization, the carrying of ore deposit, down-hole, rock all are to concentrate the drop shaft of packing into scraper, concentrate then and put fortune; Thereby scraper and personnel are more frequent in the activity of drop shaft mouth; In the past in order to prevent that scraper from shovel fortune process falling accident taking place, and be provided with safe car stop at the drop shaft edge, but safe car stop can not guarantee effectively that personnel are in the safety work of drop shaft mouth.
Summary of the invention:
The purpose of the utility model will provide a kind of exactly can prevent effectively that personnel from weighing down well, convenient and practical anti-fall chain.
The purpose of the utility model is achieved in that a kind of anti-fall chain; Form by the safety car stop; The both sides that it is characterized in that tunnel, described safe car stop top are fixedly connected round steel respectively, and the inboard of round steel is fixedly connected with hook, and the two ends of iron chains flexibly connect with hook respectively.
An optimum implementation of the utility model is: round steel is at least five, and above the safety car stop, whenever vertically arranges at a distance from 0.2 meter.
The utility model compared with prior art has the following advantages:
Because adopted the both sides in tunnel, safe car stop top to be fixedly connected round steel respectively, the inboard of round steel is fixedly connected with hook, the two ends of iron chains respectively with the form of structure of linking up with flexible connection, thereby simple in structure, easy to use, prevented that effectively personnel from weighing down well.

1, round steel 2, iron chains 3, hook 4, safe car stop
The specific embodiment:
The both sides in tunnel, safe car stop 4 top are fixedly connected round steel 1 respectively, and the inboard of round steel 1 is fixedly connected with hook 3, and the two ends of iron chains 2 flexibly connect with hook 3 respectively, and round steel 1 is at least five, and above safety car stop 4, whenever vertically arranges at a distance from 0.2 meter.
During use, when scraper loads and transports, iron chains 2 is taken from linking up with 3, concentrated to be hung on the hook 3 of tunnel opposite side, when not shoveling fortune iron chains 2 is not hung on the hook 3, thereby prevent that effectively personnel from weighing down well, guarantee operating personnel's safety.
Claims (2)
1. an anti-fall chain is made up of safety car stop (4), it is characterized in that the both sides in tunnel, described safe car stop (4) top are fixedly connected round steel (1) respectively, and the inboard of round steel (1) is fixedly connected with hook (3), and the two ends of iron chains (2) flexibly connect with hook (3) respectively.
2. a kind of anti-fall chain according to claim 1 is characterized in that round steel (1) is at least five, and whenever vertically arranges at a distance from 0.2 meter in safety car stop (4) top.
