Abstract
The utility model discloses an electrified multifunctional double-line flying trolley, which comprises a crawling ladder frame. A connection device connected with a rope ladder is arranged on the lower portion of the crawling ladder frame, and walking wheels are arranged on the upper portion of the crawling ladder frame. Another group of walking wheels is further arranged above the walking wheels of the crawling ladder frame. The group of walking wheels located at the upper position is movably connected on the crawling ladder frame, and has unfolding and folding states relative to the walking wheels located at the lower position. When the group of walking wheels located at the upper position is unfolded, distance between the group of walking wheels located at the upper position and the walking wheels located at the lower position is identical to the distance between vertical double-splitting leads. The electrified multifunctional double-line flying trolley has the advantages that the walking wheels located at the upper position and the walking wheels located at the lower position are in movable connection so that all the walking wheels can flexibly pass through the adhered double-splitting leads so as to separate the double-splitting leads. In addition, the electrified multifunctional double-line flying trolley can be used in construction of the double-splitting leads in a normal state, thereby effectively reducing the difficulty of a normal double-line flying trolley for entering the vertical double-splitting leads, and simultaneously is suitable for single lead coil-out operation.
Description
Technical field
The utility model relates to a kind of the utility model and relates to multi-functional driving, particularly charged multi-functional two-wire driving.
Background technology
Because two parallel wires show as the power of attracting each other under the effect at electric field force when the identical electric current of direction of passage.Operating double bundle conductor can be considered two parallel wires, while direction of passage, the electric current that size is identical, and under the effect of electromagnetic force, homophase double bundle conductor sub-conductor has the trend that attracts each other.During normal the operation, electromagnetic force is smaller between sub-conductor, generally can not stick together; Particularly span was big when the big electric current of high load capacity moved but run into; Or the lead temperature rise there are differences; And designed and the influence of factor such as bad, the long-time running of constructing; When making between sub-conductor distance undesirable, powerful rush of current is waved or received to sub-conductor in strong wind, local can instantaneous ten minutes near in addition collide.Lean on very closely or electromagnetic force that sub-conductor that collide is suffered very big, when the local suffered electromagnetic force of sub-conductor during greater than sub-conductor deadweight of this part, local adhesion just can occur.After bundle conductor a bit produces adhesion, very little near the distance between the sub-conductor of adhesion point, under the effect of electromagnetic force; Adhesion is constantly extended, until the hitch point place, under the rigidity interval action of gold utensil; Variously average out at this place with joint efforts, adhesion just stops.Distance between the lead adhesion part is very little, and when load was big, the electromagnetic attraction between 2 root leads was very big, even under the weather of strong wind, also be not easy separately.Want charged installation lead spacer just to need the suitable tools of on lead, working; And carry out on the double bundle conductor that existing driving instrument mostly only is adapted at being arranged in parallel, and vertical double bundle conductor is not had reasonably to be fit to the driving that live line working is changed now basically.
The utility model content
The purpose of the utility model is to overcome the weak point of prior art, and provides a kind of two leads that make two distances diminish that use during applicable to situation such as vertical double bundle conductor stick together to realize the charged multi-functional two-wire drivings of outlet.
A kind of charged multi-functional two-wire driving; Comprise the cat ladder frame; Be provided with the jockey that is connected with rope ladder in the bottom of cat ladder frame; Be provided with and can the cat ladder frame be hung on one group of road wheel of walking on the lead on the top of cat ladder frame, its structural feature is, above cat ladder frame road wheel, also is provided with the road wheel of another group; That group road wheel that is positioned at the top is movably connected on the cat ladder frame, its road wheel with respect to the below has and launches and pack up two states, above that group road wheel when launching with below road wheel between distance identical with distance between the vertical double bundle conductor.
This driving is can a car dual-purpose during use, can on the double bundle conductor of single conductor or vertical arrangement, use, when driving articulates on bonding double bundle conductor; Earlier link to each other the jockey of rope ladder with cat ladder frame bottom; Because the road wheel of superposed road wheel and bottom is for flexibly connecting, its road wheel with respect to the bottom has expansion and packs up two states, then only needs this moment the road wheel of bottom is hung on the lower wire; And make the road wheel on top be in collapsed state; Articulate the back operating personnel and get into lead, after rope ladder enters into the lead bonding place, because rope ladder and operating personnel's self weight can impel bonding lead separately along rope ladder; When being separated into to a certain degree the road wheel of top relatively the road wheel of below launch, and it be articulated to topping wire get final product.
The road wheel that is positioned at the top is movably connected on structure on the cat ladder frame for road wheel support and the cat ladder frame of top is hinged, and both be provided with when above the road wheel expansion time be used for positioning means for positioning.
The positioner that is used to locate the top road wheel is for adopting the connector location, and described connector or is cooperated with bearing pin or the threaded connector cooperation by the hole can also be that fixture such as employing window catch cooperates.
The jockey that cat ladder frame bottom links to each other with rope ladder is two connecting rings that are positioned at cat ladder frame bottom.
In sum, the utility model is compared the following advantage of prior art:
The charged multi-functional two-wire driving of the utility model flexibly connects owing to adopt between the road wheel of superposed road wheel and bottom, therefore can pass through flexibly in the middle of the bonding double bundle conductor, and make it separately.Also can be used for the double bundle conductor construction under the normal condition, effectively reduce the difficulty that common two-wire driving gets into vertical double bundle conductor, also be applicable to single conductor outlet operation simultaneously.

Embodiment
Below in conjunction with embodiment the utility model is described in more detail.
Embodiment 1
A kind of charged multi-functional two-wire driving shown in Fig. 1-5; Comprise that cat ladder frame 1 is provided with the jockey 11 that is connected with rope ladder in the bottom of cat ladder frame; Be provided with and can the cat ladder frame be hung on one group of road wheel 12 of walking on the lead on the top of cat ladder frame; Above cat ladder frame road wheel, also be provided with the road wheel of another group, that group road wheel that is positioned at the top is connected on the cat ladder frame, its road wheel with respect to the below has expansion and packs up two states.Above that group road wheel when launching with below road wheel between the vertical double bundle conductor of distance between distance identical; The road wheel that is positioned at the top is movably connected on structure on the cat ladder frame for walking wheel carrier and the cat ladder frame of top is hinged, and both be provided with when above the road wheel expansion time be used for positioning means for positioning.Described positioner 2 is for bolt positions, the cat ladder frame and above screwed hole is set on the support of road wheel respectively, when the top road wheel launches, position with bolt.The jockey that cat ladder frame bottom links to each other with rope ladder is two connecting rings that are positioned at cat ladder frame bottom.
