Abstract
The utility model discloses a novel detachable maintaining device for an electric transmission and distribution circuit. The novel detachable maintaining device for the electric transmission and distribution circuit comprises a tool bit, a cutting saw and extensible rods; an extensible structure of the extensible rod is formed by a short rod and a long rod; a first shaft sleeve and a second shaft sleeve are arranged on bilateral sides at the top of the short rod; a tool holder is fixedly connected to one end of the tool bit; the first shaft sleeve and the tool holder are connected through threads which are arranged outside the tool holder; a saw handle is fixedly connected to one end of the cutting saw; the second shaft sleeve and the saw handle are connected through threads which are arranged outside the saw handle; holding grooves are formed on bilateral sides of the lower portion of the long rod. The novel detachable maintaining device for the electric transmission and distribution circuit has the advantages of having a detachable function, solving the problem the tool bit and a saw head are aged or abraded, being simple in utilization, convenient and rapid, enabling a worker to well control the force application direction of the extensible rod due to the fact that the holding grooves are formed in the long rod and accordingly eliminating safety risks due to the fact that branches are not to touch high-tension wires during falling off.
Description
Technical field:
The utility model relates to a kind of electric power tool, particularly relates to a kind of Novel dismountable power transmission and transformation line attending device, belongs to power domain.
Background technology:
At present, remove out of doors high-tension bus-bar (for example: the high-tension bus-bar of 10KV) top branch time, staff uses the instruments such as averruncator or handsaw conventionally.Because branch is nearer apart from electric wire, while using instrument of the prior art to remove branch, be difficult to avoid branch to touch high-tension bus-bar in the process dropping, thus easy detonator circuit security incident or harm staff's personal safety; Meanwhile, in the situation that carrying out extensive work, there will be tool wear, the factor such as aging, if carry a large amount of cutfits, will increase burden to staff, thereby affect outdoor operating efficiency.
The content of utility model:
The problem that the utility model solves is: overcome the deficiencies in the prior art, a kind of safe and reliable, easy to use, solid firm, portable Novel dismountable power transmission and transformation line attending device is provided.
The utility model is that the technical scheme that technical solution problem is taked is:
a kind of Novel dismountable power transmission and transformation line attending device, comprise cutter head, cast-cutting saw and expansion link, described expansion link forms Collapsible structure by quarter butt and stock, in the both sides on quarter butt top, be respectively arranged with the first axle sleeve and the second axle sleeve, one end at described cutter head is fixedly connected with hilt, outer setting at hilt has screw thread, and the first axle sleeve and hilt are together by a threaded connection; In one end of described cast-cutting saw, be fixedly connected with saw handle, in the outer setting of sawing handle, have screw thread, the second axle sleeve and saw are being together by a threaded connection; Both sides in described stock bottom are respectively arranged with gripping groove.
Described expansion link is processed by insulating materials.
Positive beneficial effect of the present utility model is as follows:
1, this uses novel cutter head and hilt to tighten together by screw thread and axle sleeve, if there is wearing and tearing or aging stubbed situation in cutter head, after cutter head and hilt can being turned on by screw thread, replace with new cutter head and hilt, can be because instrument is aging or wearing and tearing affect the carrying out of outwork, convenient and swift, safe and reliable.
2, quarter butt of the present utility model right side is provided with saw head and cast-cutting saw, when cutting off thicker branch, can select first with cast-cutting saw, branch to be cut off, when branch is about to drop, by controlling the power thrusts of expansion link, make branch can not touch high-tension bus-bar in the process dropping, thereby eliminated potential safety hazard, and saw head and cast-cutting saw appearance wearing and tearing or aging stubbed situation, also, after saw head and cast-cutting saw can being turned on by screw thread, replace with new saw head and cast-cutting saw.
3, the utlity model has dismountable function, only assembling parts need be got up in use, simple in structure, easy to use, be easy to carry.
4, the utility model, by gripping groove being set at stock position, makes staff can better control the power thrusts of expansion link, has improved greatly the efficiency of outwork.
5, expansion link of the present utility model is processed by insulating materials, can in the situation that not having a power failure, carry out the maintenance of outdoor circuit, has good practical value.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to Fig. 1, a kind of Novel dismountable power transmission and transformation line attending device, comprise cutter head 1, cast-cutting saw 6 and expansion link 10, described expansion link 10 forms Collapsible structure by quarter butt 7 and stock 8, in the both sides on quarter butt 7 tops, be respectively arranged with the first axle sleeve 3 and the second axle sleeve 4, in one end of cutter head 1, be fixedly connected with hilt 2, in the outer setting of hilt 2, have screw thread, the first axle sleeve 3 and hilt 2 are together by a threaded connection; In one end of cast-cutting saw 6, be fixedly connected with saw 5, at saw, 5 outer setting had to screw thread, the second axle sleeve 4 and saw are together by a threaded connection 5; In the both sides of stock 8 bottoms, be respectively arranged with and grip groove 9, wherein: expansion link 10 is processed by insulating materials.
The utility model grips groove 9 by arranging at stock position, make staff can better control the power thrusts of expansion link 10, make branch can not touch high-tension bus-bar in the process dropping, thereby eliminated potential safety hazard, and the utility model has dismountable function simultaneously, solved the problem of the aging or wearing and tearing of cutter head and saw, used simple, convenient and swiftly.
