A kind of movable tunnel detection arm
Technical field
The utility model relates to Tunnel Engineering machinery, particularly movable tunnel detection arm.
Background technology
For highway, railway tunnel and subway in construction or in daily maintenance, all need the lining in its tunnel is carried out the detection of security and stability, because the complicacy of ground, tunnel and tunnel-liner face, it detects uses scanner unit, how could be according to the designing requirement of tunnel-liner face, carry out electromagnetic scanning, make the detection arm at radar antenna place adapt to the detection of tunnel-liner face, therefore require radar antenna can carry out the adjustment of various attitudes and angle.Also the end user is lifting radar antenna detection tunnel-liner face and is finding no this self-regulating detection arm at present.
Summary of the invention
The purpose of this utility model is: design a kind of tunnel detection arm that can be fixed on the mobile device, and this detection arm can be adjusted by the face self that the tunnel is scanned, detection arm can be carried out multi-direction rotation on request simultaneously.
The technical solution of the utility model is: it is made up of tunnel detection arm roller, radar carriage, two damping direction joints, controlled flexible rigid rod, screw mandrel, screw rod driving device, damping direction joint, horizontal rotating driving device, vertical rotating driving device, radar antennas, it is characterized in that: described controlled flexible rigid rod is made of the stationary installation and the flexible rigid rod that can be fixed on the moveable platform, and be equipped with the lower end of controlled flexible rigid rod can horizontal and vertical rotating driving device and in vertical sense of rotation damping direction joint is housed and connects; The radar carriage is connected by two damping direction joints with controlled flexible rigid rod top; Four rolling is equipped with on four jiaos of tops of its radar carriage, and radar antenna is equipped with in radar carriage bottom surface, and its four rolling upper edge is higher than radar antenna.
Described controlled flexible rigid rod is to drive screw mandrel, screw mandrel drive detection arm elongation or contraction by drive unit.
Described horizontal rotating driving device is to drive double strand chain by oil cylinder, and double strand chain drives the duplex chain wheel rotation and drives mechanical arm and laterally rotate.
Described vertical rotating driving device is to drive double strand chain by oil cylinder, and double strand chain drives the duplex chain wheel rotation and drives mechanical arm and vertically rotate.
It is laterally reaching of radar carriage bottom surface two dish torsionsprings to be housed respectively on the vertical turning axle that described two damping directions joint connects, and keeps the four rolling on the radar carriage to contact with workplace.
It is that two dish torsionsprings are housed on longitudinal rotating shaft that vertical damping due to rotation direction joint is equipped with in the lower end of described controlled flexible rigid rod, is used for regulating automatically the height of road surface and tunnel-liner face.
Under the cooperation of mechanical arm; radar antenna is fixed on the detection arm tunnel-liner face is detected; because the tunnel top lateral surfaces is an arcwall face; we have installed 4 rollers on the radar carriage, according to the specification of radar antenna; 4 roller scalable height; the protection radar antenna is not damaged; 4 rollers are close on the tunnel-liner face; under the effect of torsionspring 1, regulate automatically along the tunnel-liner arcwall face; remain radar antenna and tunnel-liner face on same one side, to reach the quality that radar antenna detects tunnel-liner face.Different and scraggly of the longitudinal surface of tunnel-liner face and pavement-height, under torsionspring 2 and torsionspring 3 effects, 4 rollers are close on the tunnel-liner face.Like this under the effect of torsionspring 1,2,3,4 rollers are close on the tunnel-liner face, make the radar antenna laterally and on longitudinal surface remains on one side with tunnel-liner face all the time, guaranteed that like this radar antenna is to the stable of the detection quality of tunnel-liner face and improve and detect quality.
But mechanical arm is according to different workplace lateral rotation, vertical rotating operation and regulate height automatically, satisfies different working environments.
Drive double strand chain 1 by oil cylinder 1, double strand chain 1 drive duplex chain wheel 1 rotation and about driving mechanical jib and carrying out laterally 90 ° rotate and can rest on the optional position; Drive double strand chains 2 by oil cylinder 2, double strand chain 2 drive duplex chain wheels 2 rotations and about driving mechanical jib and carrying out vertically 90 ° rotate and can rest on the optional position; Drive screw mandrel by the gage beam drive unit, screw mandrel drives the detection arm elongation or shrinks.
Since the tunnel top surface be arc, tunnel-liner face check point on different cambered surfaces, mechanical jib makes radar antenna detect the different point of tunnel-liner face by horizontal rotation.
Road surface and tunnel top surface elevation are different, and mechanical jib is regulated height automatically by the effect of torsionspring 3 around axle 3.
Controlled flexible rigid rod is regulated radar antenna and tunnel-liner face optimum detection position by vertically rotating, and detects to be convenient to regain as shown in figure 17 after maintenance work finishes.
Advantage of the present utility model is, simple in structure, full-automatic or straighforward operation makes radar antenna laterally and on longitudinal surface remains on one side with tunnel-liner face all the time, guaranteed that like this radar antenna is to the stable of the detection quality of tunnel-liner face and improve and detect quality.The detection of tunnel-liner face, because because the tunnel top surface is an arc, different and scraggly of the height of road surface and tunnel-liner face, be to adopt manually lifting radar antenna and stand in detection and the maintenance of carrying out tunnel-liner face on the easy framing scaffold in the past, this causes people's labour intensity big, efficient is low, dangerous, detection quality instability, the working electromagnet radiation produces certain injury to the people for a long time, for this reason, we have designed and produced tunnel detection arm at above problem, tunnel detection arm has solved above problem, overcome artificial factor affecting, can guarantee to detect the stable of quality, improve and detect quality, remove people's labour intensity, raise the efficiency.
