Abstract

The utility model relates to a universal laser detector used for detecting the positions of power supply lines of railways, subways and electric locomotives. The utility model is mainly composed of a corner laser, a right angle laser and a ruler. In the utility model, the corner laser is installed on the end part of the ruler; the right angle laser is installed on the ruler and can do left movement and right movement; the front, the back and the upper part of the ruler are respectively provided with scales used for detecting the horizontal positions, the height and the track distances of the power supply lines. The utility model is characterized in that the utility model can measure electric networks without power cut and can measure being free from the influence of strong wind, night and environment in tunnels; the weight of the utility model is only 5 kilograms, the utility model is simple and convenient and is suitable for field flowing operation; the utility model has various purposes and can detect the positions of power supply lines, the height difference of inner and outer tracks and track distances and can also be used as a theodolite when the corner laser being matched with a tripod.

Description

Omnipotent laser detecting apparatus

The utility model belongs to railway, subway electric motor car supply lines location detecting apparatus.

Existing railway, the subway electric motor car supply lines position detected, domestic employing messenger wire method is used dipstick metering, needs just can carry out behind the grid power blackout, and the whole stagnations of movement of locomotive in the electrical network have a strong impact on operation and income, and efficient is low, and labour intensity is big; And also want grid power blackout just can detect from the detector of external import, and very heavy, volume is big, two people to move.

The purpose of this practical full mold is to provide a kind of electrical network to have a power failure can detect the supply lines position, efficient height, light omnipotent laser detecting apparatus.

The utility model adopts following manner to achieve the goal: be equipped with slidingtype right angle laser instrument above the ruler at one, laser beam that it is thanked out and ruler axis normal, end at ruler is equipped with fixed corner laser instrument, its laser beam of thanking out can be rotated, vertical beam of light, Dou puts laser speed and ruler axis on same vertical plane, ruler is made with the flute profile material, bridge on a left side, on the right rail, its front, back and top rule arranged all, can detect the supply lines horizontal level respectively, height and gauge, ruler has positioning checkpoint below the both ends, be stuck in a left side, on the right rail both sides, zero scale is in the rail central point in the middle of making the ruler front, mobile right angle laser instrument, make the red point of laser beam fall to going up on the aerial supply lines, at this moment, zero reading on the ruler to laser beam, it is the horizontal level of supply lines, rotate the corner laser instrument, red point of laser beam and the red point of front laser beam and supply lines center are coincided together, at this moment, ruler form right angle triangle in two laser and the laser beam, ruler back rule reading is a bottom side length, protractor can measure the angle on base and Dou limit, promptly can calculate the supply lines height by tangent formula, and the rule above the ruler can measure gauge, an end above the ruler has surveyor's staff and band rule screw rod can detect in the turning, the outer rail difference in height.

The utility model characteristics: one is to use this instrument, can measure without grid power blackout, guarantees operation and income; The 2nd, not can measure by environmental impact yet; The 3rd, easy, only 5 kilogram weights are fit to open-air mobilization; The 4th, detection method is simple, the efficient height; The 5th, multi-functional decapacitation survey the supply lines horizontal level, highly, outside the rail difference in height, gauge, the corner laser instrument also can be mixed tripod, is used as transit and uses.

Below in conjunction with accompanying drawing embodiment is described:

Accompanying drawing is this detector synoptic diagram.

With reference to accompanying drawing, this detector is made up of corner laser instrument, right angle laser instrument and ruler, the corner laser instrument is positioned on the ruler right part, is made up of laser head (1), protractor (2), turbine (3), scroll bar (4), handwheel (5), cam and handle (6) thereof and base (7).Protractor (2) and turbine (3) are positioned on base (7) top, protractor overlaps with the turbine center of circle, dry cell is housed in the base, laser head (1) is cylindrical, radially be positioned on the turbine (3) with connecting pin, be equipped with the scroll bar (4) with its engagement below the turbine (3), the scroll bar right-hand member is equipped with handwheel (5), and the right-hand member neck is equipped with cam and handle (6) thereof; The right angle laser instrument is made up of laser head (8) and base (9), and laser head (8) is cylindrical, vertically be positioned on above the base (9), and be flute profile below the base, be positioned on above the ruler (10), dry cell is housed in the base; Ruler (10) is made with the flute profile material, the front, the back, rule is all arranged above, front chi zero is in the two rails center, back chi zero is at the turbine circle centre position, be gauging rule above, the bottom surface is equipped with insulation lath (14), following left end is equipped with fixation clamp (13), right-hand member is equipped with movable clip (16), be equipped with retracing spring and connecting rod (17) and handle (15) in the right-hand member, connecting rod (10) right-hand member is hinged on movable clip top, is equipped with the screw rod (12) and the surveyor's staff (11) of band runner band rule above the left end, and there is the rule of a slotted hole and measurement gauge at the movable clip place above the right-hand member.
