Abstract
The utility model relates to a portable insulated overcasting staff of a power transmission line, which belongs to the filed of the measurement of electric distance values of high-pressure power transmission lines, and comprises a telescopic bar body formed by at least two segments of bar bodies which are sleeved in turn, a length calibration tail is arranged on the telescopic bar body, and the front end of the telescopic bar body is connected with a hook. The utility model adopts a telescopic bar body with scales, which can be used to measure and read by one person in one time, greatly improves working efficiency, reduces a great amount of high-lift operations, and improves safe reliability. The distance between two points on high altitude can be directly read out through scales on the telescopic bar body, the measuring precision is greatly improved, single result is timely recorded, the overlapping of error valves can not be caused, and the truth of measuring results is guaranteed.
Description
[technical field]
The utility model relates to a kind of insulating bar, is applied to the fields of measurement of all kinds of electrical distance values of ultra-high-tension power transmission line.
[technical background]
In the day-to-day operation of transmission line of electricity was safeguarded, surveying work was a requisite link.Development along with society, society's power consumption is also constantly refreshing record, the thing followed be a large amount of newly-built, transform putting into operation of circuit, operating management department as transmission line of electricity, especially in the final acceptance of construction work before putting into operation in the face of transmission line of electricity, can the installation dimension of all kinds of electric clearances of verification and gold utensil annex seem particularly important by safe and stable operation after circuit put into operation.Keep enough electric clearances in order to ensure lead and shaft tower body of the tower, whether get hold of the mounting distance of stockbridge damper on lead wire and earth wire adheres to specification, usually we are to the measurements that must carry out an acceptance inspection such as mounting distance of the electric clearance and the stockbridge damper of lead and body of the tower, and its traditional measurement method is with common insulating bar and steel tape conjunction measuring.Generally be the distance of measuring earlier lead and body of the tower with insulating bar, the mark that on insulating bar, prints then, last on the shaft tower or treat to measure the mark distance that prints on the insulating bar and locate with steel tape again to ground under the operating personnel.
This measuring method is subjected to the restriction of this body structure of insulating bar, has many defectives:
1. need many people reading again after aerological measurement and reading or operating personnel will descend ground, operating process is loaded down with trivial details, inefficiency.
2. manual line error is big, and direct reading, causes error amount to superpose easily, causes the measurement result distortion.
[summary of the invention]
The purpose of this utility model is exactly to propose the portable insulation measurement bar of a kind of transmission line of electricity in order to solve problems of the prior art, can single direct measurement and reading, and can improve measuring accuracy, and prevent the error amount stack, avoid the measurement result distortion.
For achieving the above object, the utility model patent has proposed the portable insulation measurement bar of a kind of transmission line of electricity, comprise at least two sections telescopic bodies of rod that body of rod section is constituted of socket successively, the described telescopic body of rod is provided with the length scale mark, and the front end of the telescopic body of rod is connected with hook.
As preferably, be provided with blocking device between the per two adjacent body of rod sections.Adopt blocking device, the every joint of control lever can not arbitrarily be slided, target is not rocked for having, and locking between every joint reduces self error, does not have backlash, makes it easy to use smooth and easy in measurement procedure, and the measuring accuracy height reaches re-set target.
As preferably, described blocking device comprises locking copperhead and spring, and an end of described spring is fixed on the body of rod section, and the other end connects the locking copperhead.
As preferably, described hook is rotatably connected to the front end of the telescopic body of rod.Can regulate direction easily, convenient hook is ganged up with on another measurement point.
As preferably, the described telescopic body of rod adopts insulating material to make.
The beneficial effect of the utility model patent: the utility model adopts the graduated telescopic body of rod, can single disposable measurement and reading, improved work efficiency greatly, and reduced a large amount of work high above the ground, safe reliability is improved.Scale on the telescopic body of rod can directly be read the distance between 2 of high-altitude, and measuring accuracy improves greatly, and the timely record of single result can not cause the error amount stack, has guaranteed the authenticity of measurement result.
Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.
[description of drawings]
Fig. 1 is the portable insulation measurement bar of a utility model transmission line of electricity contraction state structural representation;
Fig. 2 is the structural representation of blocking device in the portable insulation measurement bar of the utility model transmission line of electricity;
Fig. 3 is the portable insulation measurement bar of a utility model transmission line of electricity extended configuration structural representation.
[embodiment]
Consult Fig. 1,2,3, the portable insulation measurement bar of transmission line of electricity comprises at least two sections telescopic bodies of rod that body of rod section 1 is constituted of socket successively, and the described telescopic body of rod is provided with length scale mark 2, and the front end of the telescopic body of rod is connected with hook 3.Be provided with blocking device 4 between the per two adjacent body of rod sections 1.Described blocking device 4 adopts the automatic blocking structure, comprises locking copperhead 41 and spring 42, and an end of described spring 42 is fixed on the body of rod section 1, and the other end connects locking copperhead 41.Described hook 3 is rotatably connected to the front end of the telescopic body of rod.Adopt blocking device, the every joint of control lever can not arbitrarily be slided, target is not rocked for having, and locking between every joint reduces self error, does not have backlash, makes it easy to use smooth and easy in measurement procedure, and the measuring accuracy height reaches re-set target.Telescopic body of rod high scale uses permanent mark, makes it not fugitive color, wearing and tearing, and makes things convenient for reading.The telescopic body of rod itself adopts insulating material to make, can the single distance of measuring easily between 2 in the high-altitude, reduced a large amount of work high above the ground, and safe reliability is improved.
During use, operating personnel at first make the telescopic body of rod at contraction state, ascend a height then a some place between two points to be measured, again with a section continuous expansion of the telescopic body of rod, can gang up with another point to be measured up to hook 3, the length that can directly launch according to the telescopic body of rod this moment is directly read the distance between 2.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
