Abstract
The invention discloses aerial wiring pliers with a track. The aerial wiring pliers comprise an upper jaw, a lower jaw, an insulating rod, a torsion spring and a bottom cover. A cylindrical portion of the lower jaw is coaxially mounted in an inner hole of a cylinder of the upper jaw in a clearance fit manner; the torsion spring is coaxially mounted at a hollow position of a cylinder of the lower jaw, one end of the torsion spring is fixedly connected with the upper jaw, and the other end of the torsion spring is fixedly connected with the lower jaw; the insulating rod is mounted at the hollow position of the inner periphery of the torsion spring, the bottom cover is welded to the lower end of the upper jaw, the insulating rod penetrates through the bottom cover, and the insulating rod and the bottom cover are mounted coaxially. By the aid of a track groove, the lower jaw moving vertically is capable of rotating along a center axis of the insulating rod, so that the problem of view blockage is solved. Owing to the torsion spring, completeness in closing and self locking of the upper and lower jaws can be realized, and the aerial wiring pliers are especially applicable to condition monitoring and routine maintenance of power equipment in the power industry.
Description
Technical field
The present invention relates to the equipment carrying out equipment Inspection and status monitoring in a kind of power domain, specifically a kind of rail mounted overhead jointing clamp, when being particularly useful for maintenance repair in the face of altitude plant maintenance wiring.
Background technology
High-altitude wiring testing apparatus is that power department carries out preventive trial and repair based on condition of component tests the one necessity equipment used, the high-altitude being mainly used in carrying out the electric equipments such as contact resistance, loop resistance, PT CT dielectric loss and electric capacity test connects electric test and detection, its objective is the first-hand real time data information obtaining POWER SYSTEM STATE parameter.The working environment of high-altitude wiring testing apparatus is complicated, testing location is generally field, is the environment of about 8.5 meters apart from floor level, and China's overwhelming majority region is subtropical climate, be attended by stronger monsoon throughout the year, thus make hi-line produce randomness wave disturbed test work, therefore, affect the many factors of test data accuracy, and there is the characteristic of Stochastic sum various factors coupling.
Tradition high-altitude wiring testing apparatus mostly is the overhead jointing clamp of Purely mechanical, and the closed manners of its jaw has pulley blocks formula, feed screw nut pair formula and spring etc.There is shortcomings in existing overhead jointing clamp: 1. upper and lower jaw conllinear, and during operation, lower jaw often blocks upper jaw thus hinders operator jointing clamp hooking to high aerial hi-line; 2. number of components is more, and overall weight is large, and connect conductor galloping when lifting bar, crank, easily topples, there is potential safety hazard; 3. jaw effectively can not remove oxide layer, the skin of paint of conductive surface, affects contact resistance, increases test error.Therefore, the key of high-altitude wiring technology is to develop the time saving and energy saving jointing clamp of lightweight, easy to operate, security, and this prior art also open question just.
Summary of the invention
The object of this invention is to provide a kind of rail mounted overhead jointing clamp, it utilizes track and spring, lower jaw is staggered with upper jaw position in operation, do not block sight line, be convenient to by upper jaw hooking on hi-line, the shortcoming that existing overhead jointing clamp weight is large, terrestrial operation is difficult, waste time and energy can be overcome, and there is simple economy, be easy to operation, the feature that security is good.
The present invention achieves the above object by the following technical programs: a kind of rail mounted overhead jointing clamp, comprise upper jaw, lower jaw, torsionspring and insulating bar, it is characterized in that, the barrel portion of described lower jaw is coaxially installed on the cylindrical hollow place of upper jaw, the two clearance fit; Described torsionspring is coaxially installed on the cylindrical middle vacancy of lower jaw, and torsionspring one end and upper jaw are fixedly connected, and the other end and lower jaw are fixedly connected; In torsionspring inner ring, vacancy is provided with insulating bar.Bottom is welded on upper jaw lower end, and insulating bar is through bottom, and insulating bar, bottom are that right alignment is installed.
The cylinder part of described upper jaw is arranged with spiral rail.
End place, described track lower end has one for locking the groove of lower jaw.
Described torsionspring has the elastic force of vertical direction and horizontal twisting resistance simultaneously.
Described upper jaw realizes staggering when upper and lower jaw is separated certain angle with lower jaw by track.
The present invention, compared with existing overhead jointing clamp, has material alterations, and its remarkable result is:
1. utilize rail mounted helicla flute make upper jaw and lower jaw both when lifting between form an angle, overcome existing overhead jointing clamp lower jaw when lifting and block upper jaw sight line so that operating difficulties, upper jaw can not catch on the problem of hi-line fast.
2. structure is simple, only has five parts, easy and simple to handle, only need to pull downwards insulating bar and upwardly insulating bar can realize opening of bit and close.
3. utilize torque characteristic and the tension and compression characteristic of spring, automatically converge along track and upper jaw and clamp after lower jaw is unlocked, making the simple work efficiency of apparatus structure high, Portable power saving.

Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is further described.
As shown in Figures 1 to 8, rail mounted overhead jointing clamp of the present invention, comprises upper jaw 1, lower jaw 2, insulating bar 3, torsionspring 4 and bottom 5.The barrel portion of described lower jaw 2 is coaxially installed in the cylindrical endoporus of upper jaw 1, the two clearance fit; Torsionspring 4 is coaxially installed on the cylindrical middle vacancy of lower jaw 2, and torsionspring 4 one end and upper jaw 1 are fixedly connected, and the other end and lower jaw 2 are fixedly connected; In torsionspring 4 inner ring, vacancy is provided with insulating bar 3, and bottom 5 is welded on upper jaw 1 lower end, and insulating bar 3 is through bottom 5, and insulating bar 3 and bottom 5 are right alignment installation.
Right cylinder 6 part of described upper jaw 1 is provided with spiral rail 7.
End place, described track 7 lower end has one for locking the groove 8 of lower jaw.
Described torsionspring 4 has the elastic force of vertical direction and horizontal twisting resistance simultaneously.
Described upper jaw 1 realizes staggering when upper and lower jaw is separated certain angle with lower jaw 2 by track 7.
Principle of work and process:
First lower jaw 2 being deviated from upper jaw 1 along track moves in the groove 8 of track 7 lower end, lifting insulating bar 3, by upper jaw 1 hooking on hi-line, toward drop-down insulating bar 3 make lower jaw 2 de-orbit 7 groove 8, the track 7 of lower jaw 2 along upper jaw 1 under the twisting resistance of torsionspring 4 transverse direction and the elastic force effect of vertical direction rotates while rise, final and upper jaw 1 closes, now can test, test complete, up lifting insulating bar 3, lower jaw 2 is made to move down in the groove 8 of track 7 lower end along track, take off jointing clamp, complete test.
