The sliding adjusting assembly 32 includes a sliding guide rail 35 and a fixed nut seat 36, the sliding guide rail 35 is symmetrically disposed on the torsion panel body 30, and the fixed nut seat 36 is symmetrically disposed on the torsion panel body 30.
The gravity sensing type sliding alarm mechanism 4 comprises a gravity sensing component 37 and a threshold value adjusting component 38, wherein the gravity sensing component 37 is arranged on the sliding guide rail 35 in a sliding manner, and the threshold value adjusting component 38 is arranged on the sliding guide rail 35 in a sliding manner; the gravity sensing component 37 comprises a sliding block 39, a sliding block pre-tightening spring 40 and a triggering piece 41, wherein the sliding block 39 is clamped and slidably arranged on the sliding guide rail 35, the sliding block pre-tightening springs 40 are symmetrically arranged on two sides of the sliding block 39, the sliding block pre-tightening spring 40 is arranged on the sliding guide rail 35, the triggering piece 41 is arranged on the sliding block 39, and when the triggering piece 41 is in contact with the alarm triggering plate 34, an alarm of the contact alarm 31 can be triggered.
The threshold adjusting assembly 38 comprises a threshold adjusting screw rod 42 and a threshold adjusting plate 43, the threshold adjusting plate 43 is clamped and slidingly arranged on the sliding guide rail 35, the threshold adjusting plate 43 is contacted with the slider pre-tightening spring 40, the threshold adjusting screw rod 42 is rotationally arranged in the threshold adjusting plate 43, the threshold adjusting screw rod 42 is in threaded connection with the fixed nut seat 36, the preset position of the threshold adjusting plate 43 and the pre-compression amount of the slider pre-tightening spring 40 can be changed through rotation of the threshold adjusting screw rod 42, and therefore the inclination angle required when the trigger piece 41 is contacted with the alarm trigger plate 34 is changed, and the inclination threshold for triggering an alarm is adjusted, and is the allowable error range of the subway rail body 6.
When the device is specifically used, firstly, a user needs to place the torsional flexible measuring mechanism 1 on the subway rail body 6, so that the steel rail travelling wheel 14 rolls on the subway rail body 6, and the steel rail travelling wheel 14 is limited by sliding and clamping the travelling wheel flange 19 and the subway rail body 6;
then the preset position of the threshold adjusting plate 43 and the pre-compression amount of the slider pre-tightening spring 40 are changed by rotating the threshold adjusting screw 42, so that the inclination angle required when the trigger piece 41 and the alarm trigger plate 34 are in contact is changed, and the inclination threshold for triggering an alarm is adjusted, which is the allowable error range of the subway rail body 6.
Then, the hub motor 53 is started, and the whole device is carried to slowly and stably travel along the subway rail body 6 through the rolling contact between the hub motor 53 and the side surface of the subway rail body 6 during rotation;
in the running process, in a straight section, the plane formed by the two groups of subway rail bodies 6 is required to be horizontal, if the plane is inclined, the sliding block 39 slides downwards under the action of gravity by the elasticity of the sliding block pre-tightening spring 40, the sliding amplitude of the sliding block 39 is related to the inclination angle of the measurement plane, and when the trigger piece 41 contacts the alarm trigger plate 34 (namely, the inclination angle of the measurement plane exceeds a preset value), the contact type alarm 31 gives an alarm to remind that the laying angle of the subway rail bodies 6 at the position is not in accordance with the regulation;
since the trolley needs centripetal force when turning, no matter the design of a road or a railway, the turning position needs to be inclined, and the smaller the turning radius is, the larger the inclination angle on the technical requirement is, since the travelling speed of the equipment is far smaller than that of the trolley, when the trolley passes through the turning position of the subway track body 6, if the torsion panel body 30 and the single-beam gantry body 9 are relatively fixed, the sliding block 39 inevitably slides towards the bending center, and the invention compensates the inclination error on the technical requirement by the following steps;
when the subway rail body 6 passes through a curved road section, the two groups of T-shaped main shafts 12 are twisted, and at the moment, the T-shaped main shafts 12 are twisted to drive the linear telescopic distance sensing assembly 20 to integrally stretch, and the elastic hydraulic pipeline 26 has slight elasticity, so that the elastic hydraulic pipeline 26 can fix the middle sleeve 24 without axial movement and can allow the middle sleeve 24 to slightly deviate in the transverse direction through deformation of the elastic hydraulic pipeline 26; when the induction telescoping rod 23 is telescoped in the intermediate sleeve 24, a fluid exchange occurs between the intermediate sleeve 24 and the telescopic compensating cylinder 28: when the linear telescopic distance sensing assembly 20 is shortened, the liquid in the middle sleeve 24 flows to the telescopic compensation hydraulic cylinder 28, so that the telescopic compensation hydraulic cylinder 28 is extended, and when the linear telescopic distance sensing assembly 20 is extended, the liquid in the telescopic compensation hydraulic cylinder 28 flows to the middle sleeve 24, so that the telescopic compensation hydraulic cylinder 28 is shortened; thereby carrying the torsion panel body 30 to twist relative to the single-beam gantry body 9, thereby maintaining the absolute angle level of the torsion panel body 30;
through the steps, whether the subway rail body 6 is at the turning position or the straight position, the torsion panel body 30 is horizontal as long as the design of the subway rail body 6 meets the technical requirements, and on the basis, the angle qualification of the subway rail body 6 at the turning position can be detected through the sliding of the sliding block 39;
the important points to be described are: the device does not detect the levelness of the measuring plane where the subway rail body 6 is positioned, but detects the deviation between the measuring plane where the subway rail body 6 is positioned and the design plane;
when the subway rail body 6 turns, the contact point of the hub motor 53 and the subway rail body 6 is no longer on the connecting line of the front rail traveling wheel 14 and the rear rail traveling wheel 14 on the same side, and rolling contact between the hub motor 53 and the side surface of the subway rail body 6 can be always maintained through the expansion and contraction of the pre-tightening telescopic rod 51.
The whole working flow of the invention is just the above, and the step is repeated when the invention is used next time.
