Abstract
The utility model relates to a tool for lively processing a bolt of a by-pass jumper clamp. The tool comprises a connecting rod, a sleeve for fastening the bolt and an insulating rod. The sleeve is detachably connected to one end of the connecting rod, and the insulating rod is rotationally connected to the other end of the connecting rod, and can rotate for 360 degree around the connecting rod. The insulating rod which satisfies bearing and insulation conditions is used for operation, and the tool which satisfies the mechanical and electrical performance is used to fasten the bolt. In the working process, the insulating rod can rotate for 360 degree around the connecting rod, thereby simplifying procedures and rapidly handling the heating defect. The insulating rod is formed by connecting insulating-rod units, so that the length of the insulating rod is determined according to requirements to keep a safe distance between a worker and a live lead, thereby realizing live work in the whole process. Due to use of the tool, the working efficiency is improved, the working cost is reduced, and the safe distance which satisfies requirements is always maintained between people and leads.
Description
Technical field
The utility model belongs to drainage thread resist technology field, relate in particular to a kind of can be with the instrument of electric treatment drainage thread cable clip bolt.
Background technology
Drainage thread and wire clamp thereof because the factors such as the vibration of wind there will be the loosening phenomenon of fastening bolt, can cause between drainage thread and wire having electric discharge phenomena in running, need to carry out fastening to bolt.In the process of transmission line operation, personnel, shaft tower and overhead ground wire etc. all must keep certain safe distance with live wire.According to the difference of electric pressure, safe distance is also not quite similar.Table 1 has been listed safe distance corresponding to common transmission line electric pressure.
The safe distance of the person and electrified body when table 1 live line working
| Electric pressure (kV) | 110 | 220 | 500 |
| Job safety distance (m) | 1.0 | 1.8 | 3.4 |
In order to ensure above-mentioned safe distance, not discharge, the accident such as electric shock, existing fastening bolt operation completes based on power failure condition or charged equipotential condition.Under power failure condition, the main instrument adopting has: spanner, wooden ladder etc., and fastening bolt flow process is as described below:
First, work director turns load and the operation that has a power failure to dispatcher's application to operation circuit;
The second, operating personnel climbs to bolt looseness place by wooden ladder, gets back to ground after fastening with spanner;
Three, work director report the work to dispatcher complete, recover power transmission.
This kind of replacing technology is cost-effective for large area fastening bolt, if but only to a place or two place's fastening bolts, the layout that need to have a power failure and operate and repeat operation Work tool in each process of changing, this can have a strong impact on the reliability of circuit.
Under charged equipotential condition, the main instrument adopting has: spanner, rope ladder, screening clothing etc., and fastening bolt flow process is as described below:
First, work director to dispatcher application to the operation circuit reclosing operation of stopping using;
The second, support staff steps on bar guiding line and hangs up properly rope ladder;
Three, operating personnel puts on screening clothing and climbs to bolt looseness place by rope ladder, gets back to ground after fastening with spanner;
Four, work director report the work to dispatcher complete, recover reclosing.
This kind of replacing technology can only be used for the circuit that cannot have a power failure, and is not suitable for the fastening bolt operation at large area or indivedual several places, all will repeat the layout of operation Work tool at every turn, and this can have a strong impact on the reliability of circuit.In addition,, if operating location is positioned at the areas such as mountain area, rope ladder etc. cannot be arranged according to the requirement of job instruction, change operation and will be difficult to carry out.
Utility model content
The utility model has overcome deficiency of the prior art, is to provide a kind of operating personnel and live wire of can making to keep a safe distance, realize overall process live line working, the instrument with electric treatment drainage thread cable clip bolt applied widely.
Concrete technical scheme of the present utility model is as follows:
A kind of instrument with electric treatment drainage thread cable clip bolt, comprise connecting rod, the sleeve for fastening bolt, insulating bar, the dismountable one end that is connected to connecting rod of described sleeve, described insulating bar is rotatably connected on the other end of connecting rod, and insulating bar can be done 360 ° of rotations around connecting rod.
Between described connecting rod and sleeve, be provided with anti-reverse tumbler, fastening for preventing that bolt from not only not having, be released on the contrary.Anti-reverse tumbler described in the utility model is preferably ratchet.
Described insulating bar is formed by connecting by insulating bar unit, and can connect between insulating bar unit, is applicable to the requirement of different distance.
The utility model adopts the insulating bar that meets stress condition and insulation condition to operate, and utilizes the instrument with electric treatment drainage thread cable clip bolt that meets mechanics and electric property to carry out bolted.In operation process, insulating bar can be done 360 ° of rotations around connecting rod, has simplified operating procedure, processes rapidly heating defect.Insulating bar is formed by connecting by insulating bar unit, determines that as required the length of insulating bar keeps a safe distance operating personnel and live wire, realizes overall process live line working.Use after the utility model, improved operating efficiency, reduced job costs, human body keeps with wire the safe distance meeting the requirements all the time.
Brief description of the drawings
Fig. 1 is the structural representation with electric treatment drainage thread cable clip bolt instrument described in the utility model.
Wherein: 1 is sleeve, 2 is ratchet, and 3 is connecting rod, and 4 is connector, and 5 is insulating bar.
Embodiment
Further illustrate the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, the instrument with electric treatment drainage thread cable clip bolt that the utility model provides, comprise connecting rod 3, the sleeve 1 for fastening bolt, insulating bar 5, the dismountable one end that is connected to connecting rod 3 of described sleeve 1, described insulating bar 5 is rotatably connected on the other end of connecting rod 3 by connector 4, insulating bar 5 can be done 360 ° of rotations around connecting rod 3.Between connecting rod 3 and sleeve 1, be provided with for preventing that bolt from not only not having ratchet 2 fastening, that be released on the contrary, ratchet 2 is inserted on connecting rod 3, and sleeve 1 is bored (in figure, not marking) with ratchet 2 by side and is connected.Above-mentioned insulating bar 5 is formed by connecting by insulating bar unit, and can connect between insulating bar unit, is applicable to the requirement of different distance.
Sleeve described in the utility model has different models, and sleeve is connected with connecting rod is dismountable, can change sleeve, to meet the demand of different bolt sizes.
While adopting the above-mentioned instrument live line working with electric treatment drainage thread cable clip bolt, comprise the steps:
