Description
Technical field
The utility model relates to a kind of multi-direction sensor of ultrasonic wave that utilizes ultrasonic measurement boring (well, groove) wall verticality.
Background technology
In urban construction and Important Project construction (such as highrise building, large bridge etc.), often need ground is reinforced at present, a kind of processing method is taked bored pile exactly; In the metro construction of certain areas, need at first to excavate deep groove, be used for building diaphragm wall.No matter be boring or deep trouth, in work progress, be difficult to guarantee necessarily vertically that this just needs to detect the verticality of (well, the groove) wall of holing.Detection method commonly used at present is to use ultrasonic sensor.Winch hangs down from boring (well, groove) mouth ultrasonic sensor with certain speed, perhaps lift by crane well head from the shaft bottom, by ultrasonic sensor constantly to boring (well, groove) wall emission ultrasonic pulse signal, and the reception inverse signal is measured borehole wall information, detect the verticality of boring (well, groove) wall or the hatching of boring (well, groove) wall, thereby reach measurement purpose boring (well, groove) wall.Obviously the performance of ultrasonic sensor and other external form all are the key factors that influence is measured.
The measuring sensor of common in the market ultrasonic drilling is cylindrical or square.Radially resistance is little, attitude stability is poor for garden column type sensor.The square sensor has certain radially resistance, and stability is had certain effect.But it is desirable not enough.
We know, a precondition measuring the verticality of boring (well, groove) wall be sensor as a reference center, require to remain on the vertical line, sensor relative bearing remains unchanged.Because the effect of the torsion of the wire rope of the winch of lifting sensor, sensor always is subjected to the influence of this power.How to reduce even to eliminate its influence also extremely important except the exterior design of the consideration outer sensor of winch design aspect.
Summary of the invention
The purpose of this utility model is: overcome the defective that the structure of above-mentioned existing ultrasonic sensor external form is brought, thereby provide a kind of external form of improving sensor to increase sensor at radially resistance, because the rotation of winch cable causes the change of sensor attitude, guarantee metastable, the multi-direction sensor that utilize ultrasonic measurement drill hole wall of sensor attitude on horizontal plane to weaken.
The multi-direction sensor that utilizes the ultrasonic measurement drill hole wall that the utility model provides comprises a ultrasonic transducer 5, it is characterized in that also comprising a square column 4 and N piece baffle plate 2 (or being called damping sheet); Described square column 4 the first half are cylinder, open a circular hole 8 respectively in four sides of square column 4, and described four circular hole 8 quadratures are installed a described ultrasonic transducer 5 in each described circular hole 8; One side of described baffle plate 2 is fixed thereon along the outer wall vertical of garden post, and its position is consistent with square column 4 respectively; The length of baffle plate 2 is identical with column part length, and width is with the outward flange of the latter half square column 4 of not exceeding cylinder.
In above-mentioned technical scheme, comprise that also one promotes support 3, with 4 fixed screws 7 described lifting support 3 is installed on the sensor, be used for and being connected of other lifting appliance.
In above-mentioned technical scheme, the diameter of described garden post is all mutually with the length of side of square column 4, also can be suitably smaller.
In above-mentioned technical scheme, described baffle plate 2 is made OBL plate for stainless steel or other resistant material, and wherein N piece baffle plate is more than 2, is preferably 4.
In above-mentioned technical scheme, described N piece baffle plate evenly distribute the column part that is installed in square column 4 around; Even distribution is better with regard to damping.
In above-mentioned technical scheme, can also on sensor, cover in the four directions of making, cable outlet hole 6 is set, be used for being connected with other measurements of sensor or control appliance and this sensor.
Advantage of the present utility model is:
The multi-direction sensor that utilizes the ultrasonic measurement drill hole wall of the present utility model, it is any direction in the cylinder outside of sensor, particularly on four direction, increase by four mutually orthogonal baffle plates, be used to increase damping, the torsion that has the rotation of winch cable to pass to sensor can be offset part or all by the resistance of flaps, reasonably shape, the big or small equidimension of design resistance plate just can be eliminated the torsion that come by wire rope transfers fully, thus maintenance sensor relatively stable on horizontal plane.Its structure as shown in Figure 2.

The 5-ultrasonic transducer 6-cable 7-fixed screw 8-circular hole that portals
The specific embodiment
Referring to figs. 2 and 3 a-Fig. 3 c, make one and utilize the four directions of ultrasonic measurement drill hole wall to sensor.
Get one section stainless steel square column 4, on four faces of the latter half of square column 4, dig out hole, a garden 8 respectively, choose four UDM100 ultrasonic transducers 5, respectively UDM100 ultrasonic transducer 5 is mounted in this hole, four gardens 8; The first half of square column 4 is processed into the garden post, and the diameter of garden post is all mutually with the length of side of square column 4, also can be suitably smaller.Make OBL plate washer 2 with stainless steel or other resistant material, amount to 4,4 plate washers 2 are fixed thereon along the outer wall vertical of garden post respectively, and its position is consistent with four drift angles of square column respectively; Distance between 4 plate washers 2 equates.
To sensor, also comprise that one promotes support 3 in four directions that the foregoing description is made, get fixed screw 7 then and will promote support 3 and be installed on 4 ultrasonic transducers 5, be used for and being connected of other lifting appliance.
Perhaps can also on sensor, cover, cable outlet hole 6 is set, be used for being connected other measurements of sensor or control appliance and this sensor in the four directions of making.
Mounted sensor profile schematic three dimensional views of the present utility model as shown in Figure 4.
The multi-direction sensor that utilizes the ultrasonic measurement drill hole wall of present embodiment, it is any direction in the cylinder outside of sensor, particularly on four direction, increase by four mutually orthogonal baffle plates, be used to increase damping, overcome the radially defective of little, the attitude stability difference of resistance of existing circular sensor (existing circular sensor 1 as shown in Figure 1a); Simultaneously also overcome existing square sensor (the existing square shape sensor shown in Fig. 1 b) and had certain radially resistance, stability has been had certain effect, but desirable not enough deficiency.Reasonably shape, the big or small equidimension of design resistance plate just can be eliminated the torsion that come by wire rope transfers fully, thus maintenance sensor relatively stable on horizontal plane, and its structure is as shown in Figure 2.
