Description
Technical field
The present invention relates to work transmission line field, be specifically related to a kind of overhead cable scaffold.
Background technology
Along with the tremendous development of national basis Facilities Construction, undergoing an unusual development of power engineering is rapid, high-tension line spreads all over motherland on both sides of the Changjiang River, in Poling Construction, allly run into Midspan sag and the highway that passes through can not be interrupted, the power line that can not land, order wire, building and flimsy young crops booth etc. all need to set up crossing frame or take other to cross over interim measure to ensure that circuit passes through.The mode of crossing frame is generally adopted to solve the transition problem of overhead transmission line at present, the crossing frame of existing overhead wire is comparatively simple, at barrier both sides erecting scaffold, electric wire is followed pull rope and is passed through from barrier overhead, this stringing mode danger coefficient is larger, once construction wrong or run into severe natural conditions, electric wire easily comes off from scaffold, so just very easily cause great traffic accident, if drop on damage existing line causing existing line, great economic loss will certainly be caused.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of overhead cable scaffold, and reliability is high, applied widely, improves the fail safe of power construction.
A kind of overhead cable scaffold, comprises two stands be arranged in parallel, is connected with telescopic crossbearer, the end face of described stand is fixedly connected with holder line platform between two end faces of described stand.
The further improvement project of the present invention is, the tetragonal body that described stand is some montants, cross bar, brace are formed by connecting, and the upper plane that described stand is stretched out in described montant upper end is connected with described holder line platform.
Further improvement of the present invention scheme is, described holder line platform by fixed head, the bearing being located at fixed head bottom surface, and is fixed on the some axis of rolling compositions above fixed head; Described bearing is distributed on corner, described fixed head bottom surface, and described bearing is inserted respectively or is inserted in the montant upper end of described stand.
Further improvement of the present invention scheme is, described axis of rolling level is equidistant to be arranged on described fixed head, and the both sides edge near described fixed head between the described adjacent axis of rolling is provided with spacing roller bearing.
Further improvement of the present invention scheme is, described crossbearer is made up of some expansion links and the vertical pole be connected between expansion link, described expansion link comprises mobile jib and adjusting rod, and described mobile jib is hollow structure, and one end of described adjusting rod is inserted mobile jib link and is fixedly connected with.
Further improvement of the present invention scheme is, the two ends cutting ferrule of described expansion link is connected on the cross bar of described stand.
Further improvement of the present invention scheme is, the two ends of described expansion link are provided with clip, and described cross bar is fixedly connected with through the card chamber of described clip.
Further improvement of the present invention scheme is, the frame top of described stand is provided with the drag-line be fixedly connected with ground.
Further improvement of the present invention scheme is, the outer surface of described stand and crossbearer is all enclosed with insulation rubber.
Further improvement of the present invention scheme is, the below of described crossbearer is provided with insulation net.
The present invention compared with prior art has the following advantages:
One, the roller bearing on holder line platform of the present invention can make pulling cable more laborsaving, also can not damage cable in the process pulled, its upper limit roller effect avoids cable because pulling is that undue force falls stand to the puzzlement brought of constructing simultaneously.
Two, the present invention is provided with crossbearer between two stands, and make structure firmer, security performance is higher, crossbearer is made up of expansion link, suitably can regulate the length of crossbearer according to spanning length, save a large amount of time compared to by many modes with rod member splicing assembling, improve the efficiency of construction.
Three, the present invention is firm in structure, and have the protector such as bracing wire, insulation net, stand and crossbearer are also enclosed with insulation rubber, and coefficient of safety is high, and rate of failure is low.

Embodiment
A kind of overhead cable scaffold as shown in Figure 1, 2, comprise two stands 1 be arranged in parallel, telescopic crossbearer 2 is connected with between two end faces of described stand 1, the end face of stand 1 is fixedly connected with holder line platform 4, in order to ensure the safety of constructing, the below of crossbearer 2 is also provided with insulation net 3, and the outer surface of stand 1 and crossbearer 2 is all enclosed with insulation rubber.The outside of two stands 1 is provided with the drag-line 5 be fixedly connected with ground from frame top.
Still as shown in Figure 1, 2, in the present embodiment, holder line platform 4 is by fixed head 41, the bearing 42 be located on corner, fixed head 41 bottom surface, and equidistant three axis of rolling 43 be arranged in above fixed head 41 of level form; The tetragonal body that stand 1 is some montants 11, cross bar 12, brace 13 are formed by connecting, the upper plane of stand 1 is stretched out in montant 11 upper end, and the upper end that the bearing 42 on holder line platform 4 inserts montant 11 is fixed.The axis of rolling 43 on holder line platform 4 can make pulling cable more laborsaving, also can not damage cable in the process pulled simultaneously.Both sides edge near described fixed head 41 between adjacent two axis of rolling 43 is provided with spacing roller bearing 44.Avoid when pulling because undue force cable falls stand thus the puzzlement brought to construction.
As shown in Figure 1, 2, 3, crossbearer 2 is made up of some expansion links 21 and the vertical pole 22 be connected between expansion link 21, expansion link 21 comprises mobile jib 211 and adjusting rod 212, and wherein mobile jib 211 is hollow structure, and one end of adjusting rod 212 is inserted mobile jib 211 link and is fixedly connected with.The structure of expansion link 21, the length of the length adjustment crossbearer can crossed over according to reality, saves a large amount of time by many modes with rod member splicing assembling than ever mutually, improves the efficiency of construction.The two ends of expansion link 21 are provided with clip 213, and clip 213 centrally axle is divided into two, and cross bar 12 is through behind card chamber, and with bolt fixing hoop 213, the connected mode of clip is fixing reliable, and is easy to operation.
