Description

Geological radar operates servicing unit in a kind of large cross-section tunnel area surface construction

Technical field

Patent of the present invention is related to Geotechnical Engineering field, and be particularly suitable for use in improvement large cross-section tunnel face work progress In, application aspect of the geological radar in advance geologic prediction.

Background technology

With the development of China's tunneling technique, the geological conditions that constructing tunnel faces also becomes increasingly complex, to ensure construction Personnel, the safety of property, Geological Prediction Technology have turned into the necessary work of the regional constructing tunnel of unfavorable geology.Geological radar As a kind of conveniently lossless short distance geophysical prospecting method, it is widely applied in advance geologic prediction.At present on the spot In operation, there is problems with:

1st, geological radar operating personnel are typically detected by the way of hand-held radar antenna contact rock mass, this detection Method inevitably will be closely contact face and tunnel non-supporting section, the tunnel roof and face of non-immediate support The problems such as there may be chip off-falling, cave in, particularly under the disturbance of radar antenna bottom surface, personnel, the safety of equipment can not ensure.

2nd, at present in construction generally using the mode of operation detection for manually praising antenna, in longspan tunnel detection, by Chassis form and personnel activity's scope are limited, and current survey line often arranges relatively simple, it is impossible to cover whole area well Face, especially for face oblique upper once the geological hazard body such as great solution cavity of prominent harmfulness, there is presently no special Convenient detection method.

Even the 3, the hand-held heavy antenna detection of the man skilled in the art person, can not be accurately controlled translational speed, and It is domestic generally to use time measurement mode at present, if the distance moved in the unit interval is inconsistent, it can not just be accurately positioned survey line The position of geological hazard body in net.

Chinese CN203056076U utility model patents disclose a kind of geologic radar detection servicing unit, including branch Dagger, the crossbeam being horizontally set between two support columns, the slide rail being arranged on crossbeam and for hanging geological radar day The suspention line of line, using the geologic radar detection servicing unit, can manually control the movement of antenna.But this device, it is first First automaticity is low, there is still a need for operating personnel work before face all the time when using, there is huge potential safety hazard;Its Secondary, using artificial operation, antenna translational speed control problem is not solved effectively;Again, arrangement of measuring-line is single, it is impossible to cloth Put conventional " well " font survey line, can not adjustment angle, the key areas such as face oblique upper can not also be realized comprehensively Covering.

The content of the invention

There is provided geological radar in a kind of large cross-section tunnel area surface construction in order to solve the above problems for patent of the present invention Servicing unit is operated, this method can be such that operating personnel are scanned in safe distance control radar antenna along specified path, it is ensured that behaviour Make the safety of personnel;And arrangement of measuring-line can be made more uniform reasonable, whole face can be covered, to reduce prediction error.

To achieve these goals, patent of the present invention is adopted the following technical scheme that:

In a kind of large cross-section tunnel area surface construction geological radar operate servicing unit, including the use of when be arranged in face Preceding framework, the top of the framework is provided with hoist engine, and the framework adjusts frame tilt angle degree, the frame by retractor device Frame is provided with the dismountable some pulleys for being used for adjusting traction path, and the cable of the hoist engine bypasses corresponding pulley and passed through Pull rope is connected with radar antenna;When radar survey line is horizontally disposed, on said frame provided with the water at angle of inclination can be adjusted Plate rail road, the radar antenna moves detection along the track;When survey line is arranged vertically, the radar antenna is hanged by draught line Hang, vertical lift is detected;During detection, the cable of hoist engine drives radar antenna automatically walk on default survey line, Realize automatic detection.

The track includes the guide rail and four Guide rollerses of two, and the Guide rollerses are installed on the four of radar antenna Angle.

The hoist engine, pulley and guide rail are fixed on the frame mounting by quick-speed jigs.

The track two ends are connected by angle demodulator with the quick-speed jigs, by adjust the angle demodulator come Adjust the angle of inclination of the track.

The guide rail is connected by electric pushrod with the quick-speed jigs, and the quick-speed jigs are fixed on chassis, are passed through The length of electric pushrod is adjusted, to adjust the angle of inclination of the track.

The hoist engine is variable-ratio remote control hoist engine.

The pull rope has two, is individually fixed in the both sides of radar antenna;Wherein one pull rope connects the elevator The cable of machine, another pull rope connects slipping tail rope.

The framework is fixedly connected by the fixture with expansion link with chassis.

Patent of the present invention has the beneficial effect that:

The present apparatus is that the manual operation generally used in the detection of tunnel working geology radar face at present is converted into machine Tool is operated.Mainly had the advantage that with the device:

The device is radar day by that can be fixed on the pulley of rigid frame optional position and the guide rail of inclination angle-adjustable Line provides the level of optional position in framework, vertical movement route.Most face regions can be covered, particularly The face immediate vicinity that manpower can not be detected, inclined angle up or down is made it have by adjusting guide rail, can be with The region of face oblique upper and obliquely downward is measured, search coverage area is increased.The survey line cloth relatively more rationally enriched at present Accuracy of the forecast can effectively be improved by putting.

The device uses wired long-distance remote control small winch, and operating personnel can carry out distant in safe distance to equipment Control operation, reduces the time that personnel are exposed to relative risk scope, personal security is effectively ensured.

Mechanically actuated is relative to manual operation, it is easier to control antenna translational speed.Time survey is carried out using geological radar During amount, in the case of without using measuring wheel, antenna only can just position front exactly by the traveling of certain speed at the uniform velocity The position of geological anomalous body and coverage, advance geologic prediction accuracy can be improved using mechanically actuated.

By quick-speed jigs wire rope hoist, pulley and track, can quick adjusting apparatus position, reduce personnel The necessary time rested on before face, it is ensured that personal security, it is easy to use.

Use track and slipping tail rope, it is ensured that the stable movement of radar antenna, improve accuracy of the forecast.

Track two ends can meet radar antenna towards requiring, in the inspection of the key positions such as face oblique upper using being hinged Preferably effect is played in survey.

Framework is adjusted by retractor device, complete equipment can be made preferably to fit the inclined face of shape, sampling is improved Quality.

The device provides a kind of more labour-saving mode of operation, by the bulky radar antenna of mechanical traction, it can subtract The physical work amount of few operating personnel, effectively improves operating efficiency.
