For solving above technical matters, the technical solution of the utility model is: the contact network cantilever device, it comprises the triangular form structure that is made of Horizontal Cantilever, oblique wrist and arm, one end of described Horizontal Cantilever, oblique wrist and arm is connected to catenary mast, an other end of described Horizontal Cantilever, oblique wrist and arm is connected to each other, its difference is: the bottom of described oblique wrist and arm is provided with length-adjustable hound, and an end of described hound is connected on the oblique wrist and arm, and an other end is connected on the catenary mast.
By above scheme, described hound comprises steel pipe socket, the middle part of described steel pipe socket is provided with the ratchet with rocking handle, two of steel pipe socket is provided with an inner screw sheath, the hand of spiral of two inner screw sheaths is opposite, be provided with screw rod in the described inner screw sheath, the coupling end of described screw rod and inner screw sheath is provided with the anticreep clip, and the other end of screw rod is provided with monaural.
By above scheme, the end that described hound is provided with monaural is connected on the oblique wrist and arm by bushing double eye, and an other end is connected on the catenary mast by cantilever base.
The contrast prior art, beneficial features of the present utility model is as follows:
1), this contact network cantilever device, principle is exactly that the load that oblique wrist and arm bears is transferred to the hound carrying, can shorten the time of changing oblique wrist and arm bar type insulator, drop to minimumly with changing the impact of operation on normal operation, reduce the economic loss that the contact system fault is brought;
2), this contact network cantilever device, do not need existing contact system is removed from the bracket device, can not cause the contact wire hard spot, guarantee the good operation state of contact system, guarantee to change construction safety and quality;
3), this contact network cantilever device, do not need car ladder or special rail driving less important work, need not existing contact system is adjusted after changing construction, labor savings reduces construction and drops into.

The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail below by the specific embodiment.
Please refer to Fig. 1 and Fig. 2, the utility model contact network cantilever device, it comprises the triangular form structure that is made of Horizontal Cantilever 3, oblique wrist and arm 4, one end of described Horizontal Cantilever 3, oblique wrist and arm 4 is connected to catenary mast 1, an other end of described Horizontal Cantilever 3, oblique wrist and arm 4 is connected to each other, be provided with length-adjustable hound 7 in oblique wrist and arm 4 bottoms, an end of described hound 7 is connected on the oblique wrist and arm 4, and an other end is connected on the catenary mast 1.
Concrete, hound 7 comprises steel pipe socket 9, the middle part of described steel pipe socket 9 is provided with the ratchet 10 with rocking handle, two of steel pipe socket 9 is provided with an inner screw sheath 11, the hand of spiral of two inner screw sheaths 11 is opposite, be provided with screw rod 12 in the described inner screw sheath 11, described screw rod 12 is provided with anticreep clip 13 with the coupling end of inner screw sheath 11, and the other end of screw rod 12 is provided with monaural 14.
Preferably, the end that hound 7 is provided with monaural 14 is connected on the oblique wrist and arm 4 by bushing double eye 6, and an other end is connected on the catenary mast 1 by cantilever base 8.
Comparison diagram 3 is traditional contact network cantilever device, and consuming time longer when artificial replacing bracket strut insulator, cost is higher, and has certain potential safety hazard.
A kind of embodiment of the utility model, being configured to of hound: it is that the positive and negative silk coarse thread of 40mm is processed into the monaural that the aperture is 20mm apart from an end of screw rod that two length are respectively 300mm, diameter, after the other end puts the inner screw sheath that matches, the Special anti-loosening clip is installed is carried out the anti-measure of taking off of taking out; It is that 400mm, diameter are the two ends of the steel pipe socket of 70mm that the inner screw sheath that installs screw rod is welded on respectively length, in the middle part of steel pipe socket ratchet and handle is installed again, makes the hound that can arbitrarily adjust.
The construction method of using the utility model embodiment to carry out is: on the oblique wrist and arm that wish is changed below the position mounting sleeve ears of the about 100mm of strut insulator, the existing bracket lower bottom base about 200mm place installation one overlap cantilever base, length adjustment device one end is hinged on the cantilever base by bolt pin, rotation is with the ratchet of rocking handle, adjust length-adjustable brace to the appropriate location, make it to link to each other with bushing double eye on the oblique wrist and arm; Rotation is with the ratchet of rocking handle, make hound stressed gradually, till dismountable to oblique wrist and arm bar type insulator connection pin, the power that this moment, oblique wrist and arm bore all is transferred to hound and bears, existing oblique wrist and arm bar type insulator is in the non-stress state, removes first the bolt pin that all the other cantilever bases connect, the swage pressing plate of removing insulator and being connected with bracket, remove the strut insulator that punctures, new strut insulator is installed; After new oblique wrist and arm bar type insulator is in place, shake the ratchet with handle, length-adjustable brace is suitably shortened, allow oblique wrist and arm again bear all loads of contact system, so just finish the work of oblique wrist and arm bar type replacing insulator.
The utility model contact network cantilever device, when carrying out existing contact system oblique wrist and arm bar type replacing insulator operation, production time can be controlled in the scope of 10min, be down to minimum with changing operation on the impact of normal operation, because construction does not need existing contact system is removed from the bracket device, can not cause the contact wire hard spot, guarantee the good operation state of contact system.Simultaneously, do not need car ladder or special rail driving less important work during construction, need not after the replacing existing contact system is adjusted, only 3 people just can finish the replacing operation, compare with the conventional construction mode, but labor savings 6 people at least of every place shorten production time 20min.This equipment safety is reliable, can effectively guarantee the person, device security in the construction, has high economy and social benefit.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
