On upper bracket, for the position of fastening screw mandrel is installed, be connected with screw mandrel swivel nut, screw mandrel bottom fixes as one with undersetting through this swivel nut again, and fastening screw mandrel upper end is provided with a fastening handle.
The affixed yoke in upper end of enhancing screw, opens a pair of connecting hole on two blocks of parallel fork plates of yoke, and two fork boards are enclosed within the crossbeam outer end of support, by bolt, the two are fixedly connected with, and the line hook of enhancing screw lower end is by the affixed one of bolt.
Make in the manner described above a power transmission line overhead ground wire lifting device, when use, the frame cover that the upper and lower bearing of support below is formed, is enclosed within on the pylon of transmission line, rotates fastening screw mandrel, and upper undersetting is clamped on pylon.Rotate and upgrade again screw mandrel, be elongated to and can allow the line hook of lower end catch on overhead ground wire to be processed, then tighten up enhancing screw, overhead ground wire is risen to the position of the work of being suitable for, can do easily maintenance and process.
Utilize the enhanced feature of power transmission line overhead ground wire lifting device, reduced the quantity of power tool, reduced labour intensity, improved operating efficiency.Can promote any turriform overhead ground wire, therefore there is good applicability.
Accompanying drawing explanation
Fig. 1 is power transmission line overhead ground wire lifting device front view.
Fig. 2 is power transmission line overhead ground wire lifting device right view.
Fig. 3 is the enhancing screw structural representation that power transmission line overhead ground wire lifting device uses.
Embodiment
Below in conjunction with accompanying drawing, as embodiment, technical scheme is further illustrated.
With reference to Fig. 1,2, the vertical bar, crossbeam 6 and the batter brace 5 that form support 4 form a right-angled triangle frame, the one end that is crossbeam 6 is affixed with the rectangular mode in upper end of vertical bar, the upper end of batter brace 5 is fixed in the middle part of crossbeam, the lower end of its lower end and vertical bar is affixed, and the angle steel that material selection intensity is high is made.Make support with two triangle frames of this spline structure, specifically at the top of two vertical bars and the each angle steel by a same material of the inner side of bottom, affixedly be rectangular frame, like this, the upper end of support body has two crossbeams 6, use again an angle steel affixed the outer end of two crossbeams 6 integral, complete the making of support 4.
With reference to Fig. 1,2, the base of support 4 is on the pylon for support 4 being fastened on to transmission line, and it is spirally connected and is formed by fastening screw mandrel 2 by upper bed-plate 3 and lower bottom base 1.Upper and lower base is all made with channel-section steel, and the notch of channel-section steel is downward, and open on the bottom land of channel-section steel in the hole that fastening screw mandrel passes; And at tapping welding swivel nut, make fastening screw mandrel 2 by swivel nut the tension that is spirally connected of upper and lower base.In order to guarantee the bonding strength of base and support 4 lower ends, in the two joint portion, weld a dihedral boss 13.
With reference to Fig. 1,3, enhancing screw 9 is the conventional tension screw mandrels of supply line's service work, pulls at silk the screw mandrel tightening structure that ring 11 both sides have screw rod bushing 18 and screw rod 19 to form, and silk is pulled screw mandrel handle 10 on ring, there are gum cover 16, handled easily in the outer end of screw mandrel handle 10; Screw handle 10 and silk are pulled between ring 11 commutator 17, is convenient to the operation of telescopic screw rod length.Just pass through the affixed line hook 12 of bolt 15 in its lower end, fixedly mount in the top a yoke 8, on yoke 8, open a pair of connecting hole.Yoke 8 is stuck in to the outer end position of opening of crossbeam 6, by connecting bolt 7, enhancing screw 9 is fixed on to the crossbeam outer end of support 4 with sus-pension.
