Description
Technical field
The utility model relates to electrician's technical field of tools, specifically a kind of telescopic ladder of being convenient to climb during for upper lower wire.
Background technology
At present in the overhead transmission line that has set up, steel pipe pole is used gradually in a large number with its simple installation, the advantage such as intensity is large, force-bearing property good, floor space is little.At overhead transmission line high-altitude power failure operation such as maintenance, upper and lower wire uses the suspension type rope ladder usually when changing the operation such as insulator.And because of the steel pipe pole reasons in structure, rope ladder can't be fixed on the steel pipe pole cross-arm, causes lower wire all need trample insulator.It is less owing to insulator string length when the 35kV circuit rolls off the production line, can directly be turned down by cross arm of tower, and 110kV and Above Transmission Lines since insulator length all more than 1.5 meters, directly comparatively difficult up and down, existing rope ladder can not be fixed at the shaft tower end, the hard ladder of hook is arranged because hook-shaped and volume problem can not guarantee job safety.
The utility model content
The purpose of this utility model is to provide firmly ladder of a kind of hanging extension, by zigzag trip and cooperating of telescopic spring control spanner realizing the flexible of ladder, upper and lower wire hard problem when being used for solving workman's conducting transmission line upkeep operation.
The technical scheme in the invention for solving the technical problem is: a kind of hanging extension is ladder firmly; comprise the ladder body; hook; telescopic spring control spanner; catch; make contact cross bar and zigzag trip; it is characterized in that; described ladder body comprises ladder and descending stair; on described; descending stair forms extension ladder; and be provided with zigzag trip and handle locking mechanism at upper ladder and descending stair cooperation place; be fixed with the cross bar of making contact that extends along the ladder Width in the bottom of descending stair; the described cross bar outer wrap insulating protective layer of making contact, described hook is fixed on the top of ladder body.
Described zigzag trip and handle locking mechanism comprise the zigzag trip that is arranged on the ladder and the telescopic spring control spanner that is arranged on the descending stair, telescopic spring control spanner one end is provided with the projection in the teeth groove that may be stuck in the zigzag trip, and is provided with the catch of set lever between telescopic spring control spanner and descending stair.
Described ladder body is Al-alloy parts, and miscellaneous part is steel part.
Described hook cross-section is rectangle, and is bolted on the ladder bodies top.
Described ladder body is made of aluminum alloy square tube, is provided with baffle plate at the two ends of upper ladder and descending stair, forms the seal at ladder body two ends.
The beneficial effects of the utility model are: by zigzag trip and cooperating of telescopic spring control spanner realizing the flexible of ladder, upper and lower wire hard problem when having solved workman's conducting transmission line upkeep operation.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
Among the figure: 1 ladder body, 2 hooks, 3 telescopic springs control spanner, 4 catch, 5 cross bars of making contact, 6 zigzag trips.
Embodiment
Extremely shown in Figure 2 such as Fig. 1, the utility model, comprise ladder body 1, hook 2, telescopic spring control spanner 3, catch 4, the cross bar 5 of making contact, zigzag trip 6, described ladder body 1 is Al-alloy parts, comprise ladder and descending stair, the top of upper ladder has been bolted hook 2, and hook 2 is the L-type bar that a cross section is rectangle, and main body is positioned at the rear side of ladder.The bottom of descending stair has been bolted the cross bar 5 of making contact, and the cross bar 5 of making contact is a square-section bar, extends certain-length to a side, in its outer wrap rubber cover is arranged.Upper ladder is outside to be connected by slide rail with descending stair inside, and be provided with extensible member at upper ladder and descending stair cooperation place, the telescopic spring that namely is fixed on the zigzag trip 6 on the ladder and is movably connected on the descending stair is controlled spanner 3, zigzag trip 6 is actual to be a zigzag block structure, one end of telescopic spring control spanner 3 is provided with the block-shaped protrusion that the teeth groove with zigzag trip 6 cooperatively interacts, spanner has two kinds of operating states, the card of corresponding projection and zigzag trip 6 with separate.Below telescopic spring control spanner 3, be provided with catch 4, be used for the locking of telescopic spring control spanner 3, make under its card that guarantees projection and zigzag trip 6 and the state and can not be free to slide, guarantee safety, in addition, because the main member of ladder body is comprised of aluminum alloy square tube, so be bolted baffle plate at the two ends of upper ladder and descending stair, make it to form the cavity of sealing, play the effect of sealing.
During use, the staff extends ladder on cross-arm after stepping on bar fully.The elongation method is for firmly pressing the control of the telescopic spring on main material spanner 3 about ladder body 1 descending stair, descending stair under Action of Gravity Field along on track between ladder and the descending stair glide, make the ladder elongation.The cross bar 5 of making contact of descending stair bottom is propped up wire, push away terraced head downwards, hang on the cross-arm until link up with 2.
