Abstract
The invention belongs to power transmission and transformation construction tool, and particularly relates to an emergency skid-resistant operation ladder. The upper end of a lower ladder body (4), the lower end of the lower ladder body (4) and the top end of an upper ladder body (2) are respectively and fixedly connected with two hoop fixing frames (5-1) of hoops through bolts and nuts (7). Skid-resistant linings (6) are embedded in the inner sides of the hoops (5) and fixed through fixing screw nuts (3), hoop fastening handles (5-2) are arranged outside one ends of the hoops (5) and are hinged to hoop fastening rings (5-4), a plurality of hoop fastening ring locking hooks (5-3) are arranged outside the other ends of the hoops (5), and the hoop fastening rings (5-4) are fastened to the hoop fastening ring locking hooks (5-3). The emergency skid-resistant operation ladder is highly economical, is capable of reducing the number of cat ladders on a line, easy to manufacture, install and maintain, suitable for power distribution safety production post, convenient and fast to use, and easy to carry.
Description
Technical field
The invention belongs to the construction of power transmission and transformation apparatus, particularly a kind of emergent non-slip operation ladder.
Background technology
In distribution line maintenance and management process, while meeting the special emergencies such as sleety weather generation broken string, need promptly be stepped on the bar operation, because of weather wet and slippery, fault point is at straight line pole or while needing the equipment such as emergency operation isolating switch, because this shaft tower is not installed cat ladder, the operating personnel uses climbers to step on bar power failure operating difficulties, stepping on bar more at need, generally to send the work high above the ground car support temporarily, but after accident occurs, need a period of time to arrive, existing manipulation ladder can not arrive construction height again, and do not possess antiskid function yet, the repairing time will seriously be incured loss through delay like this, to national economy, life brings inconvenience.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of simple in structure, easy to use, safe and reliable emergent non-slip operation ladder.
The technical scheme that technical solution problem of the present invention adopts is: emergent non-slip operation ladder comprises ladder, descending stair, upper descending stair connector, the top that is characterized in the upper end of descending stair, the lower end of descending stair, upper ladder is fixedly connected with respectively two anchor ear fixed mounts of shroud ring with bolt and nut, the anti-skidding liner of the inboard insert of anchor ear is fixed with the hold-down screw nut, the outside of anchor ear one end is provided with anchor ear button handle, the anchor ear button handle anchor ear clasp that is articulated and connected, the other end outside of anchor ear is provided with a plurality of anchor ear clasp latch hooks, and the anchor ear clasp is buckled on anchor ear clasp latch hook.
The invention has the beneficial effects as follows: emergent non-slip operation ladder has very high economy, can save the cat ladder quantity on circuit, make, install, safeguard simple, can be stepped on safely and fast the bar operation at the out of order wet and slippery weather of chance, can win the valuable repairing time, Accident prevention enlarges and the impact person, equipment and power grid security, is applicable to the safe distribution of electric power production station, easy to use, quick, be easy to carry about with one.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Fig. 1 is emergent non-slip operation ladder structural representation.
Fig. 2 is hooping structure expanded view in Fig. 1.
Fig. 3 is hooping structure locking figure in Fig. 1.
In figure, the upper descending stair connector of 1-; The upper ladder of 2-; 3-hold-down screw nut; The 4-descending stair; The 5-anchor ear; 5-1-anchor ear fixed mount; 5-2-anchor ear button handle; 5-3-anchor ear clasp latch hook; 5-4-anchor ear clasp; The anti-skidding liner of 6-; The 7-bolt and nut.
Embodiment
Embodiment, with reference to accompanying drawing 1 ~ 3, using descending stair connector 1 between the descending stair 4 and upper terraced 2 of emergent non-slip operation ladder connects, the upper and lower end of descending stair 4, upper terraced 2 top are fixedly connected with respectively two anchor ear fixed mount 5-1 of shroud ring 5 with bolt and nut 7, the anti-skidding liner 6 use anchor bolt nuts 3 of the inboard insert of anchor ear 5 are fixing, the outside of anchor ear 5 one ends is provided with anchor ear button handle 5-2, the anchor ear button handle 5-2 anchor ear clasp 5-4 that is articulated and connected.The other end outside of anchor ear 5 is provided with three anchor ear clasp latch hook 5-2, it is upper that anchor ear clasp 5-4 selects to be buckled in corresponding anchor ear clasp latch hook 5-3 according to the thickness of electric pole, and the emergent non-slip operation ladder also needs of visual electric pole construction height adopts the more piece ladder to be used in combination.
The using method of emergent non-slip operation ladder is: upper terraced 2 and the descending stair 4 of the non-slip operation ladder of meeting an urgent need launches, successively the anchor ear button handle 5-2 of the anchor ear 5 on the upper and lower end of descending stair 4 and upper terraced 2 tops is moved, select that according to the thickness of the position of electric pole of living in anchor ear clasp 5-4 is buckled in to the upper locking of corresponding anchor ear clasp latch hook 5-3 and get final product construction operation.
