Description
Technical field
The utility model relates to a kind of Safety of Coal Mine Production protector, is specifically related to a kind of tilting prevention device for underground coal mine work plane monomer column.
Background technology
Anti-down rope device structure for underground coal mine work plane monomer column of the prior art is more complicated, unhook phenomenon is there will be in use procedure, and when the monomer column generation leakage of fixing anti-down rope fag end or unloading, the anti-down rope of this group can be caused to lose anti-down effect, have impact on safety in production and operating efficiency to a certain extent, practicality is poor.
Summary of the invention
For above-mentioned prior art, the utility model provides a kind of tilting prevention device for underground coal mine work plane monomer column, and it has use safety, dependable performance, the advantage such as easy and simple to handle.
The utility model is achieved through the following technical solutions:
A kind of tilting prevention device for underground coal mine work plane monomer column, comprise a main rope or main chain, main rope is formed by connecting by wire tensioner by two wire rope, main chain is formed by connecting by wire tensioner by two round-link chains, main rope or main chain two ends are connected with S steel bar hook, on main rope or main chain, cover has some U-shaped Reinforced hooks, one end of U-shaped Reinforced hook is provided with closed-loop or semi-closed ring, the other end is provided with hook, and U-shaped Reinforced hook is enclosed within main rope or main chain by closed-loop or semi-closed ring.
Further, described S steel bar hook is fixedly connected on main rope two ends by wire clips.
Further, the end of described hook inwardly tilts, and its objective is: prevent the unhook phenomenon in use procedure.
Tilting prevention device for underground coal mine work plane monomer column of the present utility model, mode of occupation is:
Before using, first according to the length of main rope or main chain, and the canopy distance of work plane monomer column, determine the monomer column number that a main rope or main chain control, the i.e. number of U-shaped Reinforced hook needed for this group tilting prevention device, required U-shaped Reinforced hook by closed-loop or semi-closed ring string on main rope or main chain.During use, one end of tilting prevention device of the present utility model is walked around on monomer column, the end of S steel bar hook is hung back on main rope or main chain, again by main rope or main chain tension, in an identical manner the other end of main rope or main chain and monomer column are connected firmly, then the U-shaped Reinforced hook on main rope or main chain is enclosed within monomer column one by one, and the hook of U-shaped Reinforced hook is hung on main rope or main chain, then rotate the tensioning adjustment that wire tensioner realizes main rope or main chain, so namely complete the installation of one group of tilting prevention device.When needing prop drawing or mobile monomer column, the hook of U-shaped Reinforced hook is removed, can unload and mobile hydraulic prop, after moving into place, more timely by the main rope that hangs over this place or main chain, then rotate wire tensioner and make main rope or main chain tensioning.For strengthening anti-down effect, when arranging the tilting prevention device for underground coal mine work plane monomer column of the present utility model, can by some groups of tilting prevention device interlaced arrangement, concrete mode is: after installing one group of tilting prevention device, when next group tilting prevention device is installed, the monomer column at fixing main rope or main chain two ends is selected on 1st ~ 2 pillars in upper one group of effective control range of group tilting prevention device, then installs as stated above.The interlaced arrangement of tilting prevention device of the present utility model, can prevent the whole group of tilting prevention device caused because of the monomer column unloading of fixing main rope or main chain art end or leakage from losing anti-down effect, effectively raise operating efficiency, practicality rational in infrastructure.
Tilting prevention device of the present utility model, the main beneficial effect arranging wire tensioner is: in use, when main rope or main chain lax to some extent (that causes because of replacing, mobile monomer column etc. relaxes), the tensioning degree of main rope or main chain can be adjusted at any time neatly, keep best anti-down effect.
Tilting prevention device of the present utility model, can adopt round-link chain, and the main beneficial effect brought is: the end of S steel bar hook or U-shaped Reinforced hook can hang on the chain link of round-link chain, not easily breaks off relations.In addition, for U-shaped Reinforced hook, permanent position can also being played, preventing the effect of slippage (when adopting wire rope, because one end of U-shaped Reinforced hook is overlapped on a steel cord, the other end is hung on a steel cord, when monomer column is toppled over, likely can drive the slippage on a steel cord of U-shaped Reinforced hook, thus reduce the anti-down effect of tilting prevention device; And when adopting round-link chain, owing to hanging on chain link, even if monomer column is toppled over, due to the effect of chain link, U-shaped Reinforced hook also can not slippage on round-link chain, thus enhances the anti-down effect of tilting prevention device).
The main beneficial effect that one end of described U-shaped Reinforced hook is provided with semi-closed ring is: be convenient to change, increase or reduce U-shaped Reinforced hook at any time.When installing tilting prevention device, when the later stage needs to increase monomer column, without the need to dismantling tilting prevention device, directly separately getting a U-shaped Reinforced hook, being enclosed within main rope or main chain by semi-closed ring.When causing because monomer column is toppled over the damage of U-shaped Reinforced hook to need to change, without the need to dismantling tilting prevention device, directly the U-shaped Reinforced hook damaged being taken off, then separately getting a U-shaped Reinforced hook, be enclosed within main rope or main chain by semi-closed ring.
Tilting prevention device for underground coal mine work plane monomer column of the present utility model, structure is ingenious, easy to use and flexible, and anti-down effect is good, and security performance is high.Can interlaced arrangement during use, anti-down effect is better.
