Substantially cylindrical, for upper plate 221 substantially in tabular, the upper end of sleeve part passes through four connecting poles and the four of upper plate 221
A end angle is connected, wherein, sleeve part can be integrally formed with upper plate 221, also can be subsequently weldingly connected, bolt is arranged in successively
Upper plate 221, beam 28, arm box 21 bottom wall after be spirally connected by nut, certainly, also can be in the bottom wall and spiral shell of arm box 21
One beam, 28 ＇ is set again between mother, beam 28 and 28 ＇ of beam be for filtering out the high-frequency vibration that bogie is brought,
Ensure that device is stablized, it is preferred that bolt is the bolt of four M24.
The wide detection beam of the new rail of the utility model can be used for the detection of high-speed railway detection vehicle, it can also be used to subway, subway
Deng the detection of detection vehicle, it can also be used to the detection of half section of track geometry.Gyrounit 29 is installed in by it first before work
It, will on the wall extension 3113 for the mounting groove 311 that laser assembly 25 is installed in mounting bracket 31 in gyrounit mounting box 24
Camera assembly 26 is installed between two connecting plates 312 of mounting bracket 31, and passes through the slotted hole 3122 on connecting plate 312
The angle of camera assembly 26 is adjusted, to meet photographing request, and is consolidated torsional stop 35 and bearing block 22 by anti-turn bolt 36
If being connected, during work, beam body 23 is suspended on the bogie frame of track detection vehicle by arm box 21, is needed in calibration
When overturning beam body 23, anti-turn bolt 36 from bearing block 22 and torsional stop 35 is unloaded, releases torsional stop 35 and bearing block 22
Connection, so can be realized the overturning of beam body 23, beam body 23 is in overturning, laser assembly 25, camera assembly thereon
26 and gyrounit mounting box 24 overturn therewith.
The utility model was both mitigated by the way that arm box 21 is connected with hollow beam body 23 by bearing 30 and bearing block 22
The weight of the wide detection beam of rail, realizes miniaturization, lightweight structure, improves security, and convenient for overturning when safeguarding, also
The import of material all in one piece overall processing and part part can be effectively avoided, saves material and cost；Meanwhile by being set in the periphery of beam body 23
Mounting bracket 31 is put, using the structure setting of Opening, is easily installed each track detecting sensor, is also detected beneficial to subsequent rail
The update and increase of sensor, it is easy to maintain；Moreover, by setting slotted hole 3122 on the connecting plate 312 of mounting bracket 31,
It is adjusted convenient for the angle of camera assembly 26, is conducive to carry out the complete detection of beam body 23, it is convenient and strength-saving；Furthermore by two
Fixed torsional stop 35 between laser assembly 25 in two adjacent mounting brackets 31 enables bearing block 22 to be dismantled with torsional stop 35
Be connected, and then realize the fixation or relative rotation of bearing block 22 and beam body 23, overturning during in order to demarcate；In addition, pass through
The axial limiting to bearing 30 is realized in the setting of locking nut 32 and limit stop ring 34, avoids the axial float of bearing 30.This reality
It is simple with the wide detection girder construction of new new rail, there is lighter weight, broad extending space and reliable structure, be applicable in
Scope is wide, and use cost is low.
