A kind of mobile working platform for strain insulator string maintenance, it comprise the support bar of two parallel placements and across and be fixed on two pedals on support bar, the two ends of two support bars are all connected with upwardly extending for being mounted on the hanger on strain insulator string, offer at least two for the groove through tighten band on described pedal.When use, adopt two above-mentioned mobile working platforms to carry out, operator's bipod is bound on two mobile working platforms by tighten band respectively, the length of mobile working platform will adapt with the distance of the strain insulator string of both sides, the both sides of each mobile working platform all arrange two hangers, and correspondence is mounted on the strain insulator string of a corresponding side.
The downside of described pedal is fixedly connected with at least one bracing piece, and the two ends of described bracing piece are fixedly connected with two support bars respectively.
On described two support bars, all fix sheathed one first connecting tee pipe, the two ends of bracing piece are individually fixed on the first connecting tee pipe.
Described hanger is fixedly connected with by support bar corresponding to the second connecting tee Guan Yuqi being fixedly placed on support bar.
On the support bar in the second connecting tee pipe outside, be all fixedly connected with an anticreep rivet for preventing that the second connecting tee pipe from coming off, certainly, also can on the support bar in the second connecting tee pipe outside, be fixedly connected with a rivet, for preventing moving forward and backward of the second connecting tee pipe.
Between the hanger of the corresponding side of two support bars, be all fixedly connected with a reinforcement cross bar.
Compared with prior art, its beneficial effect is the utility model:
1, first turnover strain insulator string function and overhaul working platform function are united two into one, service efficiency increases greatly.
2, strain insulator string service work intensity is reduced greatly, operator passes in and out insulator string fail safe very big raising.
3, rational in infrastructure, easy to operate, possesses function mobile on insulator string, when possessing staff and moving, gravity motion trajectory is parallel with strain insulator string (reduces double swerve, increase stability), staff's center of gravity on human body axis (both hands can operation tool, complete service work) all the time when mobile and maintenance.
4, versatility is good, and kit can be suitable for the operation of different insulative substring spacing.
5, lightweight, be easy to carry.

Embodiment
Below in conjunction with the drawings and specific embodiments, content of the present utility model is described in further details.
Embodiment
Please refer to shown in Fig. 1-3, a kind of mobile working platform for strain insulator string maintenance, it comprise the support bar 1 of two parallel placements and across and the two ends of being fixed on two 2, two support bars 1 of pedal on support bar 1 be all connected with upwardly extending for being mounted on the hanger 3 on strain insulator string.The length of support bar 1 guarantees that the hanger 3 of its both sides all can correspondence be mounted on corresponding strain insulator string, the distance between two support bars 1 can, adjust according to strain insulator string spacing.When operation, can adopt two above-mentioned mobile working platforms to use simultaneously, conveniently move forward.Operating personnel can be sitting on pedal 2 and carry out operation, and while moving forward, two mobile working platforms are used alternatingly and move forward; Also bipod can be bound to respectively on two mobile working platforms, in the utility model preferred embodiment, on pedal 2, offer four for the groove 21 through tighten band, can be fixed pin by two tighten bands.According to the analysis to strain insulator string, according to Chinese visible human engineering science principle, determine that operating personnel stand on two inspection platforms in the middle of strain insulator strings, human body sole is 760 millimeters to the distance on edge on strain insulator porcelain patticoat, facilitates staff to operate maintenance.In the face of strain insulator string, both feet step down in respectively on two platforms, and bipod has certain width, ensures that gravity center of human body guarantees on human body axis, and operating personnel's back and positive in the middle of strain insulator, forms natural protection to staff.When operating personnel is displaced sideways on strain insulator string, motion track is parallel with insulator string all the time, and two strain insulator strings form all the time protection before and after operating personnel, and both hands are the complementary strain insulator string of holding up, convenient mobile and service work.
