The automatic pile integrity tester that this has lifting gear is characterized in that: adopt elastic top wheel line ball mode between the driving wheel 4 of lifting gear and the engaged wheel 5, promote engaged wheel 5 by adjusting spring 15, thereby change the pressure between driving wheel 4 and the engaged wheel 5.
The automatic pile integrity tester that this has lifting gear is characterized in that: have oblique inlet wire groove 14 together on the driving wheel 4 of lifting gear, be inclined cross main wheel 4, inlet wire groove 14 groove depths and main wheel wire casing 13 groove depth basically identicals.
The automatic pile integrity tester that this has lifting gear is characterized in that: can not produce under the situation of extruding loading and unloading cable 2 to cable.
The automatic pile integrity tester that this has lifting gear is characterized in that: lifting gear adopts flexible interpolation cone 7 to be fixed on the sound detecting pipe 9, and flexible fluting 12 is arranged on the interpolation cone 7, and cone 7 is fixed in the sound detecting pipe 9.
The automatic pile integrity tester that has lifting gear, comprise private host system, lifting gear and ultrasonic radial transducer, lifting gear has driving wheel, engaged wheel, controller, mounting angle plate and flexible interpolation cone are formed, and the lifting gear controller is by serial ports and main-machine communication, and probe inserts main frame by probe cable via lifting gear.
Lifting gear adopts gear train, main drive wheel adopts the guide wheel with two grooves, twine two cables respectively, the drive pulley group adopts the spring compression structure to compress cable, can change the pressure between line and the wheel by the spring that adjustment compresses driving wheel and engaged wheel, change friction force, make it the state that can reach non-slip.Designed the inlet wire groove on driving wheel, the fixed part of device adopts flexible interpolation cone.
The beneficial effect that the utlity model has is:
The elastic top wheel line ball mode of drive pulley group adopts friction gearing, cable is rotated with main wheel, and and do not produce slip between the main wheel, guaranteed the synchronous of two transducers, controller just can write down the distance that cable moves exactly, solve elevation and synchronous problem, thereby guaranteed the precision of test.This elastic top wheel line ball mode also has following advantage except having solved functional parameter from principle:
1. engaged wheel has elasticity under the effect of spring, increases the friction force between cable and the main wheel on the one hand, avoids sliding, and avoids cable to be damaged because of the pressure that strengthens suddenly on the other hand under the effect of spring.
2. regulate the pressure between main wheel and the engaged wheel, the different problems of thickness that can the compensating cable line.
3. volume is little, and is in light weight, can be directly installed on the sounding mouth of pipe.
The design of inlet wire groove need not be regulated holddown spring and come the separately spacing between the main wheel and engaged wheel, and cable can enter the main wheel groove.And advance in the process of cable and can not produce extruding, simplify execute-in-place so greatly, improved work efficiency cable.
The flexible interpolation cone of lifting gear is used for lifting gear is installed on the sound detecting pipe of bored concrete pile, makes cable enter sound detecting pipe along the sound detecting pipe center.This cone structure can adapt to the sound detecting pipe of different size, satisfies different field requirement, and flexible fluting is arranged on the cone, can make cone fixing more stable in sound detecting pipe.
Therefore, automatic pile integrity tester with above-mentioned lifting gear is realized information acquisition, is surveyed whole robotizations of reading, storing, and instrument reduces labour intensity when having improved measuring accuracy, testing efficiency, work efficiency is improved greatly, also met the developing direction of on-the-spot test technology.
