The multifunctional cantilever offset detector comprises a cantilever (2) of the overhead contact system arranged on an upright post (1) of the overhead contact system, a laser measurement mobile rack (4) capable of moving along an iron rail is movably arranged on the iron rail (3) below the cantilever (2) of the overhead contact system, a slide rail perpendicular to the iron rail (3) and a slider (8) are arranged on the laser measurement mobile rack (4), a hemisphere (9) is fixed on the slider (8), a rotating shaft (10) is arranged at the center of a top plane (15) of the hemisphere (9), a laser tester (5) is movably sleeved with the rotating shaft (10) through a shaft sleeve (11) at the bottom, a horizontal laser emitting lens (13) is arranged on the inner side of the laser tester (5), and a vertical laser emitting lens (14) is arranged on the top surface of the laser tester (5). By the multifunctional cantilever offset detector, offset of the cantilever can be measured accurately.
Description
Technical field
The present invention relates to the device in a kind of construction in electric railway and the operation side-play amount of contact network cantilever device measured.
Background technology
In the work progress of electrified railway power supply net, the duration General Requirements is shorter, particularly to the quality height of the prospecting of catenary mast bracket data and the work of mensuration, directly has influence on the reliability service of contact net.Prior art to the measurement of contact network cantilever side-play amount be by sunshine to bracket projection on the ground, the throughput hornwork is measured.Have the surveying work inefficiency, in the bad situation of weather condition, the error of measured data rate is large, also is not easy to the problem that operates.
Summary of the invention
The invention provides a kind of multi-functional bracket side-play amount detector, solved prior art the contact network cantilever side-play amount is measured the low and ineffective problem of existing measuring accuracy.
The present invention is by the above problem of following solution:
A kind of multi-functional bracket side-play amount detector, comprise the contact net column, be provided with contact network cantilever at the contact net column, rail below contact network cantilever is movably set with the laser measurement movable stand that can move along rail track, be provided with the slide rail vertical with rail at the laser measurement movable stand, be provided with slide block on this slide rail, be fixedly installed hemisphere at slide block, hemispheroidal top planes arranges along the surface level direction, central authorities in hemispheroidal top planes are provided with rotating shaft, bottom at the laser testing instrument is provided with axle sleeve, the laser testing instrument by the bottom axle sleeve and the rotating shaft pivot bush unit together, be provided with horizontal laser light emission camera lens at the medial surface of laser testing instrument, be provided with vertical Laser emission camera lens at the end face of laser testing instrument, it is inboard that vertical Laser emission camera lens is arranged on the center line of rotating shaft.
Be respectively arranged with slide-rule dial, circular arc scale and thermometer in hemispheroidal top planes, be provided with pointer in the inboard, bottom surface of laser testing instrument.
Be provided with level meter in hemispheroidal top planes, but the interior supporting leg of laser measurement movable stand is the supporting leg that hand-operated lifting is regulated height, the outer supporting leg of laser measurement movable stand is the supporting leg of level altitude.
The present invention is fast to the measuring speed of bracket side-play amount, and measuring accuracy is high, and job costs are low.In Line for Passenger Transportation or newly-built constant speed electrification contact network construction survey process, has widely promotional value.
