Abstract

The invention discloses a detection device for a tunnel detection vehicle. The detection device consists of five detection arms which are arranged on a detection vehicle platform (7) sequentially, wherein each detection arm consists of six parts, namely a radar trolley (1), a hydraulic winch and steel wire rope (2), a multi-stage plunger hydraulic cylinder (3), a multi-stage telescopic arm (4), a detection arm seat and a swing hydraulic cylinder (6). When the detection device works, the multi-stage plunger hydraulic cylinders (3) drive the multi-stage telescopic arms (4) to stretch; the swing hydraulic cylinders (6) adjust the swing angles of the detection arms; and the radar trolleys (1) are arranged on five appointed detection lines within a range of 180 degrees of the section of a tunnel, and are used for detecting the lined inner wall of the tunnel. After the detection, the hydraulic winch and steel wire ropes (2) drag the radar trolleys (1) to make the multi-stage telescopic arms (4) contract; and the swing hydraulic cylinders (6) are adjusted to drive the radar trolleys (1) to reach trolley accommodation positions.

Description

Tunnel detection car sniffer

Affiliated technical field

The present invention relates to a kind of new rolling stock---tunnel detection car, particularly relate to the sniffer on the tunnel detection car.

Background technology

In railway tunnel construction and maintenance process, possibly there are defectives such as crackle, hole, seepage, empty piece in the tunnel-liner inwall, and phenomenon such as can cause that tunnel-liner is fallen to be cut, seeped water, caves in causes potential danger to train operation.Therefore, need a kind of device that the tunnel-liner inwall is surveyed, so that in time find and take to remedy measure.

At present, domesticly tunnel detection is adopted simple and easy flatcar is artificial to roll, the artificial detection radar of helping is surveyed, and is each along a line sniffing tunnel-liner inwall, surveys ribbon zone, surveys the maximum 5km/h of pace.

Summary of the invention

In order to improve the efficient of tunnel detection work; The present invention provides a kind of novel railway tunnel detection device, and this device can be realized mechanized, surveys 1～5 circuit at every turn; The detection width of every circuit can reach 0.55 meter, and road speed is up to 20km/h during detection.

The technical solution adopted for the present invention to solve the technical problems is: tunnel detection car sniffer contains the separate feeler arm of five covers; Be X-shaped and be arranged on the probe vehicles platform, every cover feeler arm is made up of detection arm seat, multi-stage expansion arm, multistage plunger piston fluid pressure cylinder, oscillating motor, hydraulic wireline winch and wire rope, radar dolly six parts.The multi-stage expansion arm is to be formed by 3～4 sections throwout sleeve layer covers, and in adjacent inside and outside two sleeves, outer sleeve provides the slippage location to inner sleeve.Multistage plunger piston fluid pressure cylinder is 3～4 grades of piston rod constructions, and progression is corresponding consistent with the sleeve number of multi-stage expansion arm, adjacent inside and outside two piston rods, and its outer piston bar is the cylinder barrel of inner piston rod, and the like.The radar dolly is on the feeler arm top, and its base is fixed on the interior one-level sleeve top of multi-stage expansion arm, the landing of the flexible drive of multi-stage expansion arm radar dolly, and the radar dolly is tight against the tunnel-liner inwall when surveying operation.The bottom of multi-stage expansion arm outermost one-level sleeve links to each other with the detection arm seat through bearing pin; Multistage plunger piston fluid pressure cylinder in the top of first stage piston bar link to each other with the radar dolly, the outermost one-level cylinder barrel of hydraulic wireline winch and wire rope and multistage plunger piston fluid pressure cylinder is installed on the outermost one-level sleeve of multi-stage expansion arm through Bolt Connection respectively.Stretching of multi-stage expansion arm, elongation is accomplished by multistage plunger Driven by Hydraulic Cylinder, shrinks to pull completion by hydraulic wireline winch and wire rope.The oscillating motor two ends link to each other with the detection arm seat with the outermost one-level sleeve of multi-stage expansion arm through bearing pin respectively, and feeler arm is through the flexible swing that is implemented in the tunnel wall of oscillating motor.Five cover feeler arms all are positioned at the vehicle guard shield when regaining, and the hunting range of working separately of stretching out the back feeler arm is 45 °, mutually noninterfere.Five cover radar dollies can be respectively in the detection position of interior five appointments of the above 180 ° of scopes in ground in cross section, tunnel, survey lines along five and simultaneously the tunnel-liner inwall are surveyed, and survey the line detection width for every and can reach 0.55 meter.Flexible and the swing of five cover feeler arms all can be controlled separately, does not disturb mutually, realizes mechanization control operation.

The invention has the beneficial effects as follows; Craft detection by original changes mechanized into; Change at most by circuit of original detection and can survey five circuits simultaneously; Gait of march is brought up to 20km/h by original 5km/h after being installed on the probe vehicles, operative employee's working strength is reduced, and work efficiency can improve 20 times.
