one side of the detecting piece 404 is fixedly connected with a fixing rod 405, one end of the fixing rod 405 is rotationally connected with a reciprocating screw rod 407, the outside of the reciprocating screw rod 407 is fixedly connected with a guide wheel 406, a bearing seat 408 is arranged outside the reciprocating screw rod 407, the top of the bearing seat 408 is rotationally connected with a whipping scraper 409, and the rear side of the bearing seat 408 is fixedly connected with a limiting rod 410, so that the bearing seat 408 can drive the whipping scraper 409 to transversely move in the moving process.
The cross section of the fixed rod 405 is U-shaped, and the reciprocating screw 407 is connected with the bearing seat 408 through a ball nut pair.
The front surface of the detecting member 404 is provided with a limit groove, and the limit rod 410 extends into the limit groove.
The front of the detecting piece 404 is provided with an auxiliary mechanism 5, the auxiliary mechanism 5 comprises an elastic rope 501, the top of the elastic rope 501 is fixedly connected with the bottom of the whipping scraper 409, and the bottom of the elastic rope 501 is fixedly connected with the top of the bearing seat 408.
The front of the detecting piece 404 is fixedly connected with a collecting plate 505, one side of the top of the collecting plate 505 is fixedly connected with a fixing seat 502, and the bottom of the inner cavity of the fixing seat 502 is fixedly connected with a spring 503.
A guide rod 504 is fixedly connected to the top of the spring 503, and the fixing base 502 and the guide rod 504 are arranged on one side of the swing scraper 409.
The bottom of the fixed rod 405 is fixedly connected with a supporting rod 506, and the bottom of the supporting rod 506 is fixedly connected with one side of the top of the collecting plate 505.
One side of the bottom of the swing scraper 409 is in a guide arc shape, and the other side of the bottom of the swing scraper 409 is in a right angle shape.
When the ground detection is needed, firstly, a worker enters the vehicle body 1 and opens the vehicle body 1 into a tunnel, then, the worker needs to open the hydraulic rod 402, the hydraulic rod 402 stretches at the moment, when the stretching length of the hydraulic rod 402 is enough, the rotating plate 403 synchronously drives the detecting piece 404 to be close to the top of the tunnel, and meanwhile, the fixed rod 405 also drives the guide wheel 406 to be attached to the top of the tunnel;
if the detection needs to be performed on the side of the tunnel, a worker needs to mobilize the connecting rod 401 to a corresponding angle, and after the angle is completely determined, the worker repeats the working process;
then, a worker starts to slowly drive the vehicle body 1, at the moment, the vehicle body 1 synchronously drives the mounting plate 2 and the supporting frame 3 to move, the supporting frame 3 indirectly drives the detecting piece 404 to move in the moving process, meanwhile, the detecting piece 404 indirectly drives the guide wheel 406 to move in the moving process, at the moment, the guide wheel 406 also contacts and rolls with the top of the tunnel, and has a certain supporting force, so that the condition that the detecting piece 404 is not attached to the tunnel in the moving process and is caused to shake is prevented, and the problem of inaccurate detection in the detecting process is avoided;
in the working process, since the guide wheel 406 drives the reciprocating screw rod 407 to rotate in the rotating process, the reciprocating screw rod 407 can transversely reciprocate the bearing seat 408 in the rotating process, the bearing seat 408 can synchronously drive the whipping scraper 409 to move in the moving process, the whipping scraper 409 can scrape impurities on the inner surface of the tunnel in the moving process, the situation that the impurities damage the detecting piece 404 is prevented, and the accuracy of the detecting piece 404 in the detecting process is ensured;
since the diameter of the tyre of the vehicle body 1 is far greater than that of the guide wheel 406, when the vehicle body 1 rotates for one turn, the guide wheel 406 rotates for a plurality of turns at the moment, so that the swing scraper 409 can extremely intensively scrape and clean impurities on the inner surface of the tunnel;
when the reciprocating screw rod 407 rotates to enable the bearing seat 408 to start to move from right to left, the bearing seat 408 drives the swing scraper 409 to synchronously move, if the arc edge on the left side of the swing scraper 409 contacts with the guide rod 504, the arc edge of the swing scraper 409 drives the guide rod 504 to move downwards, meanwhile, the spring 503 is compressed, and when the swing scraper 409 slides completely over the top of the guide rod 504, the spring 503 is in rebound stretching and drives the guide rod 504 to move upwards, so that the follow-up swing operation of the swing scraper 409 is facilitated;
since the bearing seat 408 synchronously drives the limiting rod 410 to move in the limiting groove in the moving process, the bearing seat 408 is limited, so that the phenomenon of idle running does not occur;
in the working process, when the swing scraper 409 slides across the guide rod 504 from left to right, at this moment, the guide rod 504 limits the swing scraper 409, so the swing scraper 409 contacts with the guide rod 504 and starts to rotate, then the elastic rope 501 is stretched, when the distance of the bearing seat 408 moves is far enough, the swing scraper 409 slides across the guide rod 504, then the bearing seat 408 is rapidly compressed, and because the swing force of the swing scraper 409 is large at this moment, intractable and hard impurities on the inner surface of the tunnel can be removed, the situation that the detection precision is affected due to the damage of the detection piece 404 is prevented, and the practicability of the device is ensured;
in the above-mentioned course of working, because the impurity all can be by the work that throws scraper 409 and throw, so collecting plate 505 can block the impurity that throws this moment, prevent that the impurity from dropping the inside at hydraulic stem 402 and leading to breaking down, guaranteed hydraulic stem 402's long-term life, can not influence the detection precision to tunnel inside in subsequent work.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
