here is the further optimization and/or improvements to foregoing invention technical scheme:
above-mentioned reversible ratcheting tool also can comprise reversing piece; Reversing piece is arranged on ratchet carriage and does not install on one end of interior Hexagonal jacket.
above-mentioned bearing pin can be screw bolt, and strap upper end is provided with the screwed hole mated with bolt thread, and handle is provided with the through hole being greater than the large footpath of bolt thread, and strap and handle are installed together by screwed hole and through hole by bolt.
can in cylindric and be provided with external screw thread bottom above-mentioned clamping plate seat, insulating rod top is provided with internal thread groove, is fixedly installed togather bottom clamping plate seat with insulating rod top by screw thread.
reasonable and compact in structure of the present invention, easy to use, it is hinged by the strap at insulating rod top and reversible ratcheting tool, and push-and-pull insulating rod drives ratchet carriage rotation, carry out the installation or removal work of bolt, nut, avoid power failure operation, there is simple to operate, portable feature, save a large amount of human and material resources simultaneously, avoid electric quantity loss, after increasing work efficiency, also can bring economic benefit intuitively, guarantee the safe and reliable operation of electrical network.
Accompanying drawing explanation
accompanying drawing 1 is the axle side structure schematic diagram of preferred embodiment.
accompanying drawing 2 is that the A of the reversible ratcheting tool of accompanying drawing 1 is to structural representation.
coding in accompanying drawing is respectively: 1 is strap, and 2 is clamping plate seat, and 3 is insulating rod, and 4 is handle, and 5 is ratchet carriage, and 6 is bearing pin, and 7 is interior Hexagonal jacket, and 8 is reversing piece, and 9 is through hole.
Embodiment
the present invention by the restriction of following embodiment, can not determine concrete execution mode according to technical scheme of the present invention and actual conditions.
in the present invention, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. determines according to the Butut direction of Figure of description.
below in conjunction with embodiment and accompanying drawing, the invention will be further described:
as shown in accompanying drawing 1,2, this ratchet spanner being used for ultra-high-tension power transmission line comprises reversible ratcheting tool, strap 1, clamping plate seat 2 and insulating rod 3; Reversible ratcheting tool comprises the handle 4 and ratchet carriage 5 that are fixed together, one end of ratchet carriage 5 is provided with the interior Hexagonal jacket 7 matched, strap 1 " V " font in opening upwards, handle 4 away from one end of ratchet carriage 5 by the rotatable opening being arranged on strap 1 upper end of bearing pin 6, and bearing pin 6 axis and ratchet carriage 5 axis being parallel, the lower end of strap 1 is fixed with clamping plate seat 2 and insulating rod 3 successively.Bearing pin 6 axis and ratchet carriage 5 axis being parallel, can when push-and-pull insulating rod 3 carries out installation or removal bolt, nut operation, ratchet carriage 5 rotates evenly, making push-pull effort maximizing efficiency when being converted to the twisting resistance of reversible ratcheting tool to bolt, nut, reducing labour intensity during operating personnel's work high above the ground; Insulating rod 3 installation direction can with bearing pin 6 axes normal, such operating personnel is when climbing up shaft tower and carrying out handling bolt, nut, and push-and-pull insulating rod 3 is more laborsaving; The insulating rod 3 of different length can be changed in operation according to the voltage number of high-tension line, guarantee operating personnel's personal safety; Interior Hexagonal jacket 7 is single rotation direction power transmission with ratchet carriage 5; Interior Hexagonal jacket 7 can replace with interior 12 corner apertures sleeves.
