Described outer catheter dee slides in described guide rail by roller.
Described outer catheter by roller in the interior slip of described outer catheter dee 4.
Adopt four joint telescopic boom top-mounted tow chain devices of technique scheme, compared with prior art, the utility model has the advantage of: whole towing chain mechanism facilitates all devices to remove separately, only need remove by the inner catheter head and from the 3rd telescopic boom, just inner catheter can be able to be extracted out from outer catheter 5 front and back; Outer catheter can directly take out from the outer catheter dee simultaneously; Whole towing chain mechanism maintains easily, and due to what adopt, is open design, when in towing chain device internal hydraulic pressure oil pipe and cable outlet fault, can conveniently observe and keep in repair, will whole oil pipe and cable from towing chain device, take out; The anti-dust accumulation of whole towing chain mechanism is effective, and in complexity, in severe sandblast environment, this mechanism can facilitate makes the hole of sand and dust from interior outer catheter leak down smoothly, prevents that sand and dust from piling up, and eliminates and answers sand and dust to pile up the impact on the towing chain mechanism operation.
The accompanying drawing explanation
Fig. 1 is existing towing chain device schematic diagram.
Fig. 2 is the utility model towing chain device schematic diagram.
Fig. 3 is that the utility model towing chain device is walked the pipeline schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, what its keystone configuration of the self-propelled high altitude vehicle top-mounted tow chain device generally used now adopted is enclosed design.In being mainly manifested in and with protective cover 21, whole towing chain device being enclosed in, the first drag chain 25 and drag chain conduit 23 also come the jib top, and the second drag chain 22 1 ends are fixed on drag chain conduit 23, and drag chain conduit 23 can slide on guide rail 24.
Due to what adopt, it is enclosed design, when aerial lift device is operated in dirty environment, particulate matter enter protective cover and catheter interior are inevitably arranged, go down to cause particulate matter to pile up for a long time, affect the work of whole drag chain, serious will directly damage drag chain and drag chain conduit.When the drag chain pipeline damages, because conduit is enclosed, can not facilitate directly maintenance simultaneously.
Referring to Fig. 2 and Fig. 3, basic arm 7 is provided with the first telescopic boom 8, the second telescopic boom 9 and the 3rd telescopic boom 10, guide rail 2 is fixed on basic arm 7, outer catheter dee 4 one ends are fixedly mounted on the head of the first telescopic boom 8, the other end by roller in the interior slip of guide rail 2, outer catheter 5 one ends are fixedly mounted on the head of the second telescopic boom 9, the other end by roller in the interior slip of outer catheter dee 4, inner catheter 6 one ends are arranged on the head of the 3rd telescopic boom 10, the other end is in the interior slip of outer catheter 5, lower drag chain 1 one ends are fixedly mounted on basic arm 7 on the position away from the root of basic arm 7, the other end is fixedly mounted on an end of the root of close basic arm 7 on outer catheter dee 4, an end of the root of close basic arm 7 on upper drag chain 3 one end fixed installation inner catheters 6, the other end is fixedly mounted on the head of the first telescopic boom 8, the first steel pipe 11 is set to lower drag chain 1 installation place along the side of basic arm 7, the first 12 1 of sebific ducts connect the first steel pipe 11, the other end is the tail end to outer catheter dee 4 through lower drag chain 1, the second steel pipe 13 connects the first sebific duct 12 and leads to actuating unit by described upper drag chain 3, inner catheter 6 successively along outer catheter dee 4 supreme drag chain 3, the second sebific ducts 14 connection the second steel pipes 13 in side.
