For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cross-arm card code device, the first circular arc anchor ear is connected by the secured adjusted bolt through the first installing plate and the second installing plate with one end of the second circular arc anchor ear, the second installing plate bottom is provided with pulley and mounts ring, on the 3rd installing plate of the first circular arc anchor ear other end, be installed with movable erection bolt, the not closed bolt mounting groove of offering on the 4th installing plate of movable bolt and the second circular arc anchor ear other end matches, the 3rd installing plate bottom is provided with pulley and mounts ring, the first installing plate, the second installing plate, on the 3rd installing plate and the 4th installing plate, be separately installed with cross-arm card.
On the screw thread of movable erection bolt, pad is installed.
Bolt mounting groove is " L " type mounting groove.
Pulley mounts ring for " U " type ring.
The cross-arm card code device that the utility model provides, by secured adjusted bolt and movable erection bolt, the first circular arc anchor ear and the second circular arc anchor ear are fixedly mounted on to the masthead of H-frame pole and three link rods, pulley in the second installing plate and the 3rd installing plate bottom mounts and on ring, hangs up pulley, after two cross-arms being gone up to masthead through the rope of pulley roller, be placed on cross-arm card, adjust two cross-arms parallel, alignment bolt mounting holes, bolt is tightened through installing hole, make two cross-arms tightly clamp electric pole, unscrew movable erection bolt and take off the installation that the utility model completes cross-arm, can solve the two cross-arms of H-frame pole and three link rods and mount and dismount difficult problem, install, convenient disassembly, only movable erection bolt need be placed in " L " type bolt mounting groove and tighten, during dismounting, be also only movable erection bolt need be unscrewed and can be completed dismounting.And through safety verification, can effectively bear the weight of ascending, descending cross-arm and instrument goods and materials, use this instrument can make Ground Operation personnel assist operating personnel on bar to carry out the carrying up and down of cross-arm, reduced operating personnel's quantity on bar simultaneously, can effectively reduce operating personnel's labour intensity on bar, improve safety type, reduce the activity duration, improve the installation of H-frame pole cross-arm, dismantlement work efficiency comprehensively.
Use the utility model that two cross-arms are installed and tested, to manually and fixing link statistics consuming time as shown in the table:
Above-mentioned statistics shows: it is 19 minutes that two cross-arm needs 4 people of H-frame pole, used time are on average installed, with prior art, the two cross-arms of H-frame pole being on average installed needs 6 people, within 40 minutes consuming time, compares, required number greatly reduces, and has saved man-hour, has improved efficiency; In addition, through safety verification, after this instrument installs, can effectively carry 500 kilograms of loads and not produce distortion, and cross-arm weight is no more than at most 200 kilograms, so the utility model meets safety condition, meet security requirement.
By secured adjusted bolt, can regulate coordinating of the first circular arc anchor ear and the second circular arc anchor ear, can adapt to the electric pole in different tips footpath, tip footpath as conventional in rural area distribution is φ 150mm, φ 190mm cement electric pole.
