Abstract
The utility model discloses a double-locking detection device of a transmission line linear unit shell. The device is characterized by comprising a main body straight pipe, wherein three adjustable measuring rods are respectively arranged on the same section of the outer surfaces at the two ends of the main body straight pipe uniformly and are also provided with locating measuring bridges; the adjustable measuring rods and the main body straight pipe are fixed by double locking devices; the locating measuring bridges have radians so that the three locating measuring bridges at the same end of the main body straight pipe are uniformly distributed on the same circumference; the double locking devices comprise bolt locating sleeves installed on the main body straight pipe; a bolt for connecting the main body straight pipe with each adjustable measuring rod is arranged in each locating sleeve; an upper lock nut and a lower lock nut are arranged at the upper and lower ends of the bolt respectively; and a connecting rod is welded between the adjustable measuring rods corresponding to each other at the two ends of the main body straight pipe. The detection device has the beneficial effects that an existing single measuring device is improved into a comprehensive measuring device, so that the problems of out-of-roundness of the inner diameter of the long-distance shell, difficulty in determining the correction point and the like are solved and the finishing operation is facilitated.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of linear unit housing of gas insulated power transmission line.
Background technology
At present, the linear unit housing of gas insulated power transmission line in-process measurement is the measurement mechanism structure of single cubing, single-point, individual event, due to linear unit shell be cylindric, volume is large, circularity, linearity require high, can not composite measurement, just can not solve whole assembly problem.
The utility model content
The purpose of this utility model is to provide a kind of transmission line of electricity linear unit shell locking pick-up unit.
To achieve these goals, by the following technical solutions, a kind of transmission line of electricity linear unit shell locking pick-up unit, it is characterized in that: described device comprises the main body straight tube, each evenly arranges three adjustable measuring staffs on the outside surface same cross section at main body straight tube two ends, also has the location on adjustable measuring staff and surveys bridge; Described adjustable measuring staff and main body straight tube are fixed by double locking apparatus, described location is surveyed bridge and is had radian, make three location survey bridges of the same end of main body straight tube be evenly distributed on same circumference, described double locking apparatus comprises the Bolt to position cover that is arranged on the main body straight tube, be provided with a bolt that connects main body straight tube and adjustable measuring staff in this locating sleeve, two ends, bolt up and down also are respectively arranged with upper locking nut and lower locking nut, and wherein main body straight tube two ends are welded with connecting link between corresponding adjustable measuring staff in twos.
The utility model will have analytical measurement now and be improved to comprehensive measurement device, make the problems such as long out-of-roundness apart from the housing internal diameter and adjusting point are not easy to determine obtain solution, facilitate correction work.By this device, the out-of-roundness of linear unit housing of gas insulated power transmission line and supporting insulator and the assembly problem that linearity causes have not effectively been solved; Simultaneously, owing to having adopted double locking apparatus, guaranteed stability and reliability that this utility model is used, its design concept is simple, and is easy to use, and composite measurement is effective.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of double locking apparatus in Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1 to Figure 3, a kind of transmission line of electricity linear unit shell locking pick-up unit, comprise main body straight tube 3, each evenly arranges three adjustable measuring staffs 2 on the outside surface same cross section at main body straight tube 3 two ends, also have the location on adjustable measuring staff 2 and survey bridge 1, this location is surveyed bridge 1 and is had certain radian, makes three location survey bridges 1 of main body straight tube 3 same ends be evenly distributed on same circumference; Wherein main body straight tube two ends are welded with connecting link 5 between corresponding adjustable measuring staff in twos.Adjustable measuring staff 2 is fixed by double locking apparatus 4 with main body straight tube 3.
Described double locking apparatus 4 comprises the Bolt to position cover 4-2 that is arranged on main body straight tube 3, be provided with a bolt 4-4 who connects main body straight tube 3 and adjustable measuring staff 2 in this locating sleeve 4-2, two ends, bolt 4-4 up and down also are respectively arranged with upper locking nut 4-1 and lower locking nut 4-3.
During use, first adjust the length of adjustable measuring staff, make its internal diameter that is suitable for housing to be detected, adjust rear employing double locking apparatus it is locked; Then, device is put into housing, put into from an end, the other end is pulled out, if there is out-of-roundness in the centre, this device can't pull, and so just is easy to determine the out-of-roundness position of housing; Simultaneously, this device can also coordinate with other cubings, measures length.
The utility model will have analytical measurement now and be improved to comprehensive measurement device, make the problems such as long out-of-roundness apart from the housing internal diameter and adjusting point are not easy to determine obtain solution, facilitate correction work.By this device, the out-of-roundness of linear unit housing of gas insulated power transmission line and supporting insulator and the assembly problem that linearity causes have not effectively been solved; Simultaneously, owing to having adopted double locking apparatus, guaranteed stability and reliability that this utility model is used, its design concept is simple, and is easy to use, and composite measurement is effective.
