The work process of the present embodiment is:
During detection state:
Vault detecting device 3: the drive rod 10.3 of quadric chain (fold mechanism 10) lifts obliquely upward, now go up the upper end of folding rod 10.1 to be pulled and move down, telescoping mechanism 8 entirety driving vault detecting device 3 rotates clockwise, until stopping during plumbness.Restarting servomotor 9.4 and decelerator, drive steel wire rope to rotate, drive radar 7 to stretch out until itself and tunnel-side distance reach predetermined value, in the process, regulating wheel 9.5 is mainly steel wire rope and provides guiding and tension.
Upper side wall detecting device 4: unclamp the connecting bolt supporting toggle 16 with base 8.1, regulate telescoping mechanism 8 angle until radar 7 detection faces is parallel with tunnel-side, then tight a bolt, the angle of inclination enabling base 8.1 remains unchanged, rotating top rotary table 11.1 makes telescoping mechanism 8 keep 15 ° of inclination angles with tunnel-side vertical direction, so that flexible avoidance, limited block matches with stop screw and prevents horizontal rotation mechanism 11 from excessively rotating in the process.Then, unclamp the screw for fixing big square steel 12.3 and little square steel 12.2, adjust the height of little square steel 12.2 to predetermined value, insert the screws in the hole, location of big square steel 12.3 and little square steel 12.2 correspondence and be fixed.Restarting servomotor 9.4 and decelerator, drive steel wire rope to rotate, drive radar 7 to stretch out until itself and tunnel-side distance reach predetermined value, in the process, regulating wheel 9.5 is mainly steel wire rope and provides guiding and tension；Fairlead 8.4 is mainly expansion link 8.2 and provides guiding, improves the force-bearing situation of expansion link 8.2, improves expansion link 8.2 motion rigidity.Finally adjust the spacing of support bar and base 8.1, make return spring be exactly in original state.
Lower wall detecting device 5: rotate the telescoping mechanism 8 on rotating base 198.1 so that it is radar 7 is vertical with tunnel-side.Starting servomotor 9.4 and decelerator, drive steel wire rope to rotate, drive radar 7 to stretch out until itself and tunnel-side distance reach predetermined value, in the process, regulating wheel 9.5 is mainly steel wire rope and provides guiding and tension；Fairlead 8.4 is mainly expansion link 8.2 and provides guiding, improves the force-bearing situation of expansion link 8.2, improves expansion link 8.2 motion rigidity.
After above-mentioned action completes, move special purpose vehicle 1 to by railway engineering car 17 and start tunnel-side and vault detection process.
When vault detecting device 3 runs into protrusion, owing to the vault in high ferro tunnel is provided with contact rack, a contact rack touching sensing device 6 it is respectively arranged with before and after vault detecting device 3, the fiber-glass pole touching contact rack in sensing device 6 is touched by two contact racks, absolute type encoder transmits a signal to PLC13, and then judge fiber-glass pole angle of inclination, determine whether touching contact rack, if touching, driving mechanism 9 in vault detecting device 3 drives telescoping mechanism 8 to bounce back, and is highly declined by radar 7 and avoids contact rack.
When upper side wall detecting device 4 runs into protrusion, actively dodging: when protrusion is bigger, radar 7 is prone to detection, after radar 7 finds protrusion, sending a signal to PLC13, PLC13 drives telescoping mechanism 8 to bounce back by driving mechanism 9, and radar 7 retraction is avoided protrusion.Flexibility is dodged: when protrusion is less, radar 7 not easily detects, owing to radar 7 can not find protrusion, therefore radar 7 will not bounce back and be to continue with moving along original route and then knocking protrusion, radar 7 retard motion, horizontal rotation mechanism 11 meeting automatic rotation under drag effect suffered by radar 7, now spring is stretched.After radar 7 rotated protrusion, the spring being stretched can restore to the original state under counteracting force, and radar 7 is synchronized to retract initial position, continues detection.
Tunnel lower wall detection environment is simpler than tunnel vault/upper side wall detection environment, therefore without horizontal rotation mechanism 11 and lifting mechanism 12.
During non-detection status after detection, the drive rod 10.3 of the quadric chain of vault detecting device 3 bounces back, and makes folding rod 10.1 move upward, and promotes telescoping mechanism 8 to rotate counterclockwise to horizontal level, and radar 7 is retracted by simultaneous retractable mechanism 8.Upper side wall detecting device 4 drops to elemental height by lifting mechanism 12, adjusts telescoping mechanism 8 to level by support toggle 16 simultaneously, is retracted by radar 7 by telescoping mechanism 8.Radar 7 is retracted by lower wall detecting device 5 by telescoping mechanism 8, and is rotated by telescoping mechanism 8 to vehicle-mounted base 2 space.
Above-mentioned detection process is controlled by PLC13, and PLC13 is assigned instruction also by hand-held control box 14 and split type switch board 15 by operator simultaneously.
Compared with prior art, the advantage of this device is in that:
1, device adopts vehicle-mounted form, namely arrives and namely uses, it is not necessary to frequently mounting or dismounting, and transhipment is convenient, adapts to railway in operation Tunnel testing " Window time ", can realize tunnel is semi-automatic, Aulomatizeted Detect.
2, during non-detection status, vehicle-mounted tunnel-liner radar 7 detecting device can be parked in special garage, it is to avoid electrified radar 7 lifts equipment and is exposed in open-air atmosphere, and outdoor adverse circumstances are bigger to the damage of equipment.
3, device can realize vault/upper side wall/lower wall three line in closing military high ferro double track tunnel and detects simultaneously, can realize vault/upper side wall/lower wall five line at the common single-track railway tunnel in Changting, Fujian and detect simultaneously, and detection efficiency is high.
4, device is except can be applicable to conjunction military high ferro double track tunnel, the common single-track railway tunnel in Changting, Fujian, also can be applicable to as in the such vcehicular tunnel in big tunnel, ground, it is achieved railway tunnel and the semi-automation of vcehicular tunnel, Aulomatizeted Detect.
5, each survey line TT&C system separate operation, more convenient to operate.
6, each side line of device adopts the convergent-divergent of steel wire rope to pull the guide rail slide block 8.3 being loaded with geological radar 7 at moving on rails, and maximum rising or falling speed, can quick avoiding barrier up to 5.65m/s.
7, after device only needs each survey line operative employee to carry out hand push button operation or arrange parameter, automatic telescopic, largely alleviate labor intensity.
8, the detection of a line only needs operator, saves labour force, and available a plurality of line detects simultaneously, improves detection efficiency.
Embodiment 2: when this device is applied to single-track tunnel, structure as shown in Figure 7 and embodiment 1 are substantially the same, it is distinguished by: include 3, two upper side wall detecting devices 4 of a vault detecting device and two lower wall detecting devices 5, said two upper side wall detecting device 4 is respectively arranged on two side surface upper part of vehicle-mounted base 2, and said two lower wall detecting device 5 is respectively arranged on two side lower of vehicle-mounted base 2.Its operation principle is identical with embodiment 1 with operating process.
The above, be only preferred embodiment of the present utility model, and structure of the present utility model is not done any pro forma restriction.Every any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, such as: when tunnel-side is too high or wide, upper side wall detecting device 4 or vault detecting device 3 can be set up according to practical situation, all still fall within the scope of the technical solution of the utility model.
