Description
Technical field
The utility model belongs to movable supporting frame, particularly relates to a kind of mobile radar antenna holder detecting tunnel-liner quality.
Background technology
Railway, the Non-Destructive Testing of highway tunnel lining quality are the important means of tunnel construction process quality control, adopt GPR detection method can to tunnel lining concrete thickness, density, come to nothing, reinforcing bar distribution etc. detects fast, it not only overcomes traditionally with the incomplete defect of detection that the range estimation of a capping and punching selective examination exist, and be a kind of high resolving power, high-accuracy, carry out the high-tech means of Non-Destructive Testing fast and efficiently, therefore GPR detection method is widely used in Inspection of Tunnel Quality detects.
The existing the ground coupling radar antenna comprising measuring wheel and fan-shaped porous hinged seat is applicable to the detection of tunnel-side and ground lining quality, but exist when carrying out the survey line such as tunnel vault and haunch and detecting and use inconvenient outstanding problem, be mainly reflected in the following aspects, (1) because tunnel has suitable height, can only detect by the simple and easy stand be welded on excavator or shovel loader, and at least need two operating personnel to stand in hand rest antenna on simple and easy stand, testing is made to become work high above the ground, not only labour intensity is large, also there is certain danger, (2) because tunnel ground flatness is poor, inevitably occur excavator or shovel loader advance in phenomenon of jolting, jolting of vehicle must cause the ground coupling antenna also to occur jolting, therefore be difficult to meet that radar antenna is close to hole wall, the testing conditions of the motion continuously that remains a constant speed, what the ground coupling antenna occurred jolts and will produce interference to time section image, (3) also because tunnel ground flatness is poor, the vertical range height on tunnel vault and ground differs, and in travelled by vehicle testing process, needs the lift height of constantly adjustment excavator or shovel loader.But because lighting condition in tunnel is limited, air quality is poor, the operating personnel on stand are caused to be difficult to effective cooperation with the call answering between driver, often cause that antenna departs from lining cutting surface, excavator or shovel loader loiter in testing process, cause and detect that data image is smudgy and continuity is poor.(4) on the time section of georadar image, each point position should to detect mileage corresponding with reality, requires that every 5 meters are done a mileage mark on tunnel side wall.But during actual detection, the existence of operating personnel's hand rest antenna swings and forms snakelike advance, and the trend of antenna is not straight line truly, even use mileage wheel, mileage and the actual mileage of record also have a certain distance.In addition, due to the error on line of sight of instrument operator, be difficult to ensure the accurate of radar map picture point position, when arraying data, affect the interpretation of inspection result position.
Summary of the invention
The utility model proposes a kind of mobile radar antenna holder detecting tunnel-liner quality to solve the ground coupling radar antenna technical matters that existence use is inconvenient when carrying out tunnel vault and haunch survey line detects.
The utility model takes following technical scheme for achieving the above object: a kind of mobile radar antenna holder detecting tunnel-liner quality, comprise the ground coupling radar antenna and measuring wheel thereof and porous hinged seat, feature is, described mobile radar antenna holder is provided with pulling type flat-bed trailer, this flat-bed trailer rear portion is provided with the axle bed of axle sub-truss cant beam bottom, middle front part is provided with the bracing frame of symmetrical pulley, the ground coupling radar antenna porous hinged seat is connected with the upper shaft of truss cant beam, symmetrical oblique pull wire rope one end and truss cant beam upper end fix, the symmetrical pulley that symmetrical oblique pull wire rope supports with bracing frame respectively engages, the symmetrical oblique pull wire rope other end is provided with the pouring weight that truss cant beam is faced upward.
The utility model can also take following technical measures:
The porous hinged seat of described the ground coupling radar antenna is supported with direct current spotlight and power supply thereof, and direct current spotlight beam is towards ground milepost.
Described direct current spotlight is glare light electric torch.
Described pulling type flat-bed trailer front end is provided with towbar.
The described oblique pull wire rope other end is respectively equipped with the pouring weight that truss cant beam is faced upward.
The beneficial effects of the utility model and advantage are: this mobile radar antenna holder with pulling type flat-bed trailer for carrier, namely removable under the traction of vehicle, can be detected as picking-up vehicle drags by common light duty vehicle, and without the need to the large-scale lifting vehicle such as excavator, shovel loader, reduce resource input.The ground coupling radar antenna is by the lifting of truss cant beam, truss cant beam keeps state of facing upward under oblique pull wire rope, pulley and pouring weight mating reaction, the height change of tunnel construction site ground can be adapted to and there is autoregulation, thus the ground coupling radar antenna and measuring wheel thereof are fitted with the lining cutting intimate surface of tunnel vault and haunch all the time.Work high above the ground personnel, without the need to personal height operation, thoroughly free by this mobile radar antenna holder from the miscellaneous work of hand rest radar antenna, can greatly alleviate testing labour intensity, eliminate high-altitude working safety hidden danger.The testing environment in the especially limited tunnel of adaptating lighting condition of the embodiment with direct current spotlight, can realize mileage mark and the accurate location detecting radar image.The utility model has testing process traveling continuously and be that straight line truly, radar data clear picture are stable, the high-quality measured outstanding advantages of detection efficiency.
