Abstract
The utility model discloses a saw-tooth sickle for the electrified operation of a transmission line, comprising a connecting pipe which is arranged vertically and is provided with an internal thread; the upper end of the connecting pipe is provided with a connecting plate; the plane of the connecting pipe is in parallel with the axis of the connecting pipe; the middle part of the connecting plate is provided with a through hole slide way which is in parallel with the axis of the connecting pipe, and the upper part thereof is provided with a screw hole; and the screw hole and the through hole slide way are detachably connected with a sickle. The utility model mainly solves the quality and technical standard requirements in the electrified operation process of the transmission line, can detach the sickle when in use, installs an upward pulling pin clamp, a centralizer, an integrated operation device, a measuring instrument and other tools for electrified operation, minimizes the labor intensity of an operator and the special operation end replacement frequency, improves the safety of the operator, simplifies operation steps, shortens the electrified operation time and greatly improves the quality control standard.
Description
Technical field
The utility model belongs to the power industry technical field, relates in particular to a kind of hot line maintenance sawtooth reaping hook that is used for the maintenance of power transmission line shaft tower, measurement test, operation maintenance.
Background technology
Charged insulating bar is widely used in the power system transmission line live line working, live line working is one of the technological means most effectively that guarantees the transmission line safe operation, improves line efficiency, in the normal operation maintenance of transmission line, adopt the method for live line working can in time eliminate the major defect that circuit is in operation, rationally adjust power system operating mode, reduce interruption duration,, guarantee safety, the stable operation of electrical network for enterprise creates high economic benefit.
In existing live line working, charged insulating bar that is adopted and the operation tool that matches all more single (operating head that adapts must be changed in position of just every operation), in events in operation, repeatedly change the attended operation head of insulating bar and just can finish an overhauling project, and insulating bar is passed to ground or prepares two to three eradication edge action bars; The labour intensity, the operating efficiency that have increased the operating personnel virtually are low, have increased project operation step and work high above the ground work amount, have strengthened the job safety risk factor; There are branch or foreign matter keeping off probably in the place of work high above the ground, influence the efficient and the fail safe of live line working, be easy to occur dangerous play.At present, on the market and domestic each power equipment manufacturer multifunctional combined operating head of carrying out the knife saw operation when also not producing available live line working.
The utility model content
The utility model is in order to solve weak point of the prior art, provide a kind of simple in structure, volume is little, in light weight, be convenient to dismounting, hot line maintenance simple and efficient to handle sawtooth reaping hook.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: hot line maintenance sawtooth reaping hook, comprise that vertical setting has the tube connector of internal thread, the tube connector upper end is provided with connecting plate, connecting plate plane and tube connector parallel axes, the connecting plate middle part is provided with the through hole slideway with the tube connector parallel axes, and connecting plate top is provided with screw, and screw and through hole slideway are removably connected with reaping hook.
On the center line that is centered close to the through hole slideway of described screw.
Described reaping hook comprises the arc cutter hub of knife bar and knife bar upper end, and the cutter hub edge is provided with sawtooth and blade side by side.
There is cross recess described connecting plate lower end.
Adopt technique scheme, will have the locking that is spirally connected of the tube connector of internal thread and insulating bar, be connected with reaping hook with the through hole slideway by the screw on the connecting plate, hand-held insulating bar can be pruned the branch or the foreign matter of working area; Knife bar is fixedlyed connected with the through hole slideway with the screw of connecting plate by bolt, and the cutter hub edge is provided with sawtooth side by side and blade is used for the branch or the foreign matter that influence operation are pruned; Cross recess is used for cooperating with pin on the insulating bar, prevents from that tube connector and insulating bar are spirally connected to rotate after the locking again.
The utility model is reasonable in design, simple in structure, be easy to dismounting, can be in the work of transmission line hotline maintenance, effective and safe distance between strict control operation personnel and the circuit electrified body, guarantee the every construction technology quality in the operation maintenance maintenance, meet the quality standard of DL/T 741-2001 " overhead transmission line operating standard " regulation fully.Mainly solve the quality in the hot line maintenance process, the requirement of technical standard, in use reaping hook can be pulled down, the instruments such as the pincers of pulling pin, centralizer, integrated operating means, measuring instrument of installing carry out live line working, reduce operating personnel's the labour intensity and the frequent number of times of replacing dedicated operations termination to greatest extent, to operating personnel's fail safe, the step that simplifies the operation, shortening live line working time, quality control standard improves greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of reaping hook in the middle of the utility model.
Embodiment
As depicted in figs. 1 and 2, hot line maintenance of the present utility model sawtooth reaping hook, comprise that vertical setting has the tube connector 1 of internal thread, there is cross recess 2 tube connector 1 lower end, the upper end is provided with connecting plate 3, connecting plate 3 planes and tube connector 1 parallel axes, connecting plate 3 is provided with through hole slideway 4, connecting plate 3 is provided with the through hole slideway 4 with tube connector 1 parallel axes, connecting plate 3 tops are provided with screw 5, on the center line that is centered close to through hole slideway 4 of screw 5, screw 5 and through hole slideway are removably connected with reaping hook.Reaping hook comprises the knife bar 8 of fixedlying connected with through hole slideway 4 by bolt 6 and bolt 7 and the screw 5 on the connecting plate 3, and knife bar 8 upper ends are provided with the cutter hub 9 of arc, and cutter hub 9 edges are provided with sawtooth 10 and blade 11 side by side.
The tube connector 1 that will have internal thread earlier is spirally connected with insulating bar, pin on the insulating bar cooperates its locking with cross recess 2, when maintenance or operating area when having branch or foreign matter to block, operation insulating bar, 11 pairs of branches of sawtooth 10 on the cutter hub 9 and blade or foreign matter are pruned.When other live line working of needs, reaping hook can be pulled down, install instruments such as the pincers of pulling pin, centralizer, integrated operating means, measuring instrument.
