Embodiment Construction

[0034] 1. The geometric dimensions of the invented tunnel detection arm (in mm):

[0035] Maximum dimensions: width × thickness × height 750 × 700 × 3500 as shown in the figure.

[0036] The maximum measuring radius is 2300.

[0037] The maximum carrying capacity is 30kg.

[0038] The minimum size after shrinkage: width x thickness x height 1500 x 600 x 1500 as shown in the picture.

[0039] 2. Radar bracket:

[0040] According to the different specifications of the radar antenna, the size of the radar bracket is also different. The geometric size of the radar bracket is made according to the radar antenna. image 3 and Figure 4 shown.

[0041] 3. Two-position damping direction joint:

[0042] In the longitudinal direction, the transverse axis is determined by the Install the blocking arm in the middle (the blocking arm is welded by 60X40X4X75 and 50*50*4*80 square tubes), drilled in the 50*50 square tube The hole in which the transverse shaft is installed, and a di...

Abstract

The invention relates to the tunnel construction machine, in particular to a movable tunnel detection arm, which consists of a roller, a radar bracket, a two-position damping directional node, a controllable telescopic rigid rod, a lead screw, a lead screw driving device, a damping directional node, a transverse rotating driving device, a longitudinal rotating driving device and a radar antenna. The invention has the advantages of simple structure and full-automation or remote control operation so that the radar antenna and a tunnel lining face are kept on the same plane in the transverse direction and the longitudinal direction. In this way, the stable and improved detection quality of the radar antenna on the tunnel lining face can be ensured.

Description

technical field [0001] The invention relates to tunnel engineering machinery, in particular to a movable tunnel detection arm. Background technique [0002] For highways, railway tunnels and subways during construction or in daily maintenance, it is necessary to detect the safety and stability of the lining surface of the tunnel. Due to the complexity of the tunnel ground and the tunnel lining surface, the detection radar How can the antenna device perform electromagnetic scanning according to the design requirements of the tunnel lining, so that the detection arm where the radar antenna is located can adapt to the detection of the tunnel lining, so the radar antenna is required to be able to adjust various attitudes and angles. At present, it is also used to carry the radar antenna to detect the lining surface of the tunnel, but the automatic adjustment detection arm is not found. Contents of the invention [0003] The object of the present invention is to design a tunne...
