The utility model is linked together by the adjustable joint on worktable and girder.
The vehicle body of subway contact net operation ladder vehicle and car stop adopt aldural section bar to make, weight is light, intensity height, cross section force design are reasonable, and polylith can be splitted at any time, the heaviest weight is no more than 14kg, dismounting only needs 2-3 minute, so transport, upper and lower road is very convenient, only needs 2 people just can complete.
Nylon manufacture selected by wheel, insulation is reliable, weight is light, without noise, intensity height, good toughness, one group of ladder wheel there is a ground connection nylon wheel for band steel ring, nylon wheel adopts twin shaft to hold, slide laborsaving, there will not be and slide down, simultaneously owing to 3 wheels adopt the insulation wheel of nylon material, make two rail can not form loop, thus do not affect driving signal. Meanwhile, Working Table can be convenient in the subway tunnel of different headroom to construct.
The utility model by change ladder car vehicle body, car stop, the material of wheel, working platform height adopt adjustable and adopt braking pull-rod type to embrace the anti-tilting apparatus of hoop, not only increase novel contact net operation ladder vehicle operating efficiency, and increase security.
The beneficial effects of the utility model are:
The utility model can meet contact network construction in the tunnel of the different overhead clearance of subway, and this device weight is light simultaneously, intensity height, has the function preventing from tumbling, economic and practical.
