Abstract

A special sensor clamp for ultrasonic guided-wave detection of a guardrail upright column on an expressway is applied to the ultrasonic guided-wave length measurement field. The clamp adopts a clamping structure formed by two semicircular hoops (4) connected by a buckle; the internal diameter of the clamp is matched with the external diameter of the guardrail upright column; 10-16 bolts (3) pointing to the center of each hoop are uniformly arranged in each semicircular hoop (4) along the outer edge of the hoop; each bolt (3) is connected with a sensor base (1); the sensor base (1) can be adjusted along the radial direction of each hoop through rotating the bolt (3); a propping sensor base (1) and springs of semicircular hoops (4) are also sleeved on the bolt (3); and a radio frequency plug for splicing a sensor (6) is arranged in the sensor base (1). By using the clamp, the guardrail upright column on the expressway can be accurately and efficiently detected. The clamp has the advantages of simple structure and convenient and stable installation and use.

Description

High speed highway guardrail upright post ultrasonic guided wave detecting sensor special anchor clamps
Technical field
The utility model relates to a kind of high speed highway guardrail upright post ultrasonic guided wave detecting sensor special anchor clamps.
Background technology
The traffic safety anticollision barrier of highway plays a part effective reduction vehicular impact power, slow down the speed of a motor vehicle, prevent that vehicle from going out roadbed, and steel column is the main load bearing component of guardrail.Yet the construction of traffic safety anti-collision facility steel column is a concealed work, also is lifeline engineering, and the healthy quality of construction is directly connected to the integrally-built safe operation of guardrail.In China, exist unit in charge of construction's sincerity degree low, construction Supervision is difficult to carry out the effectively problem of supervision of overall process.Therefore, use inferior materials and turn out substandard goods in the work progress, the thing of having a mind to shorten the steel column buried depth happens occasionally, and causes the protective action of anticollision barrier to reduce greatly, does not reach designing requirement, has caused the construction quality defective., penetrate in the stratum simultaneously, will local corrosion take place and cause the corrosion cracking of column through the long-time fence upright that uses as liquid such as moisture, humid air, rainwater because fence upright environment of living in is more abominable.Because highway guard rail upright post partly is embedded in the roadbed of highway, as seen its failure mode exists very strong disguise, it is effectively detected particularly bury the very big difficulty of ground part existence.
The employing method is that column is extracted check at present, perhaps excavates also useful manual method of knocking vibrations.The fence upright detection technique is a supersonic guide-wave Non-Destructive Testing new technology the most easily, and the sensor of using in this detection technique mainly is the piezoelectricity loop, method cost height, the efficient of pasting the piezoelectricity loop are low, can not realize the recycling of piezoelectric patches, this method only is fit to breadboard conceptual phase, can't be applied in the actual engineering and go.So the purpose of this utility model is developed high speed highway guardrail upright post ultrasonic guided wave detecting sensor special anchor clamps exactly, cooperate high speed highway guardrail upright post ultrasonic guided wave detecting sensor special, and be applied in the practical project detection, to realize detection rapidly and efficiently.
Summary of the invention
In order to overcome sensor installation complicated problems in the high speed highway guardrail upright post ultrasonic guided wave detecting, the utility model provides a kind of high speed highway guardrail upright post ultrasonic guided wave detecting sensor special anchor clamps, can realize easy accessibility between sensor and anchor clamps and the convenience that mounts and dismounts on fence upright.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: design a kind of high speed highway guardrail upright post ultrasonic guided wave detecting sensor special anchor clamps, these anchor clamps are two yoke configurations that the semicircle garter spring that connects by buckle is formed, the internal diameter of clip and the external diameter of fence upright adapt, the bolt at 10-16 sensing garter spring center evenly is set along the garter spring outer in each semicircle garter spring, respectively connect a sensor base on each bolt, making sensor base pass through swivel bolt can be along the garter spring radiai adjustment, also be with the spring that holds out against sensor base and semicircle garter spring on the bolt, be provided with the radio frequency plug of the sensor of can pegging graft in the sensor base.Radio frequency plug can adopt MMCX type radio frequency plug.
The sensor that has MMCX type radio frequency socket is fixed by MMCX radio frequency plug and sensor base, can realize the easy accessibility between sensor and anchor clamps.
Described two semicircle garter springs can be realized the easy accessibility of whole sensor system helping simultaneously realizing that the contact pressure between each sensor and column is even.
This programme utilizes spring to realize having enough contact pressures between sensor and the column, has guaranteed the contact pressure basically identical of each sensor and column.
The internal diameter of described semicircle garter spring and the external diameter of column adapt.
These anchor clamps can judge easily whether each sensor effectively is coupled with column, after sensor and anchor clamps are assembled, because the effect of spring, bolt is in stress, when being fixed on the column, has corresponding contact force between sensor and column to sensor owing to have compression spring, its elastic force to make with these anchor clamps, this moment, bolt was in the state of not stressing, so can be by judging whether bolt is in relaxed state and determines coupling situation between sensor and column.
The beneficial effects of the utility model are: because these anchor clamps can be fixed on the uniform of sensor symmetry on the column, and can realize the adjustable of contact force between sensor and column, adopt these anchor clamps to cooperate the corresponding sensor degree of depth with can measuring burying of high speed highway guardrail upright post accurately, and be not subjected to the influence of column surrounding medium.Use these anchor clamps can carry out the detection of precise and high efficiency to high speed highway guardrail upright post.And these anchor clamps is simple in structure, easy to install, stable.
