Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
The Maintenance and Repair personnel of power system need usually in work high above the ground, and the protection operation person and device security have very important significance conscientiously.Because work high above the ground inevitably needs to use of seat belts, and the framework on repair apparatus that utilizes of safe and reasonable hangs safety belt, does not need ascend operation, is the important measures of guarantee equipment and the person.
The present invention can solve safety belt and hang inconvenient, dangerous, insecure problem, and its concrete technical measures taked are realized by suspension body 11 and blocking mechanism.See Fig. 1, the upper end of described suspension body 11 is provided with hook 1, lower end is provided with lower draw-bar 9, described upper hook 1 and lower draw-bar 9 are divided into the both sides hanging body 11, upper hook 1 is used for mounting with the fixing framework on repair apparatus, lower draw-bar 9 is for mounting with safety belt, and locking mechanism can form self-locking to upper hook 1; Described blocking mechanism comprises locking piece 2, guide rod 5, Compress Spring 4 and supporting plate 7, locking piece 2 gap is placed on the two ends of hook 1, can move up and down along upper hook 1 and suspension body 11, supporting plate 7 is positioned at immediately below hook 1, and be vertically fixed on the lower end hanging body 11, Compress Spring 4 is between locking piece 2 and supporting plate 7, Compress Spring 4 rely on locking piece 2 and supporting plate 7 spacing, described guide rod 5 is guide spiro rod, guide rod 5 upward sliding through supporting plate 7 and Compress Spring 4, and is spirally connected with the nut 3 be fixed on below locking piece 2.Wherein guide rod 5 and nut 3 are spirally connected, and not only structure is simple, are also convenient to change Compress Spring 4.
Further improved plan, be on described supporting plate 7, be provided with guiding cover for seat 6, guide rod 5 is through guiding cover for seat 6, and the lower end of Compress Spring 4 is supported on above guiding cover for seat 6, the setting of guiding cover for seat 6 can shorten the stroke of Compress Spring 4, increases the elastic force of Compress Spring 4.
As preferred technical scheme, be installed with locking screw 10 at the free end of described lower draw-bar 9, the safety belt be linked into is provided constraints, prevent safety belt from coming off.
Further improvement project, the section of described suspension body 11 is square, a hole of locking piece 2 is square hole, shown in Figure 2, can prevent locking piece 2 from rotating, locking piece 2 is further limited, locking piece 2 can not be rotated when suspension body 11 moves up and down, in order to avoid the free end of upper hook 1 not easily passes, easily operate when the present invention being hung up or takes off.
Spacing effect is also played in split pin 8 wherein.
The following detailed description of use procedure of the present invention:
In use, need the position with the drop bar 12 of three claws, the present invention being sent into aerial suspension by upper end, the length of general drop bar is 2 or 3 meters, also have and lengthen telescopic drop bar, requirement for height can be met, wherein, upper end is the one of the drop bar that power system often uses with the drop bar of three claws, for prior art, by the handle of operational grounding rod, three claws above can block object, and under the operation of handle, can object be displaced downwardly in the barred body of drop bar, namely the present invention is the inspiration by the drop bar often used, without ascend operation.
See Fig. 3, first, on ground, safety belt or middle connecting band are hung on lower draw-bar 9, locking screw 10 is threaded into withstand and hangs body 11; Operational grounding rod 12, with the spacing head of three claw clamping guide rods 5 of drop bar 12 upper end, guide rod 5 is under the pulling force of drop bar 12, locking piece is retracted, and Compress Spring is compressed, and locking piece moves down along hanging body, and throw off with upper hook, then upwards lift the present invention, the present invention is delivered on the framework of the equipment chosen, upper hook is hung architecturally; Unclamp drop bar 12, Compress Spring 4 resilience, locking piece moves up into hook, can crossbeam is locked in upper hook 1; When needing dismounting, with the spacing head of the upper end clamping guide rod 5 of drop bar, operational grounding rod 12, then guide rod 5 moves down under the effect of drop bar 12, drive locking piece 2 to move down, throw off to locking piece 2 and upper hook, to crossbeam from deviating between upper hook 1 end and locking piece 2.
This device takes full advantage of upkeep operation field apparatus, and volume is little, lightweight, easy to carry, project organization is simple, hang and use flexibly, operating personnel's high-rise working scope of activities is not limited to, can use and maintenance Work tool easily, reduce the upkeep operation time, improve power supply reliability.Achieve safety belt height and hang low use, can effectively ensure maintainer's personal safety, this device is not only applicable to power transformation operation Overhaul site high-rise working, is applicable to other platforms yet or has work high above the ground needs to hang the occasion of safety belt.
