Description

Rock fixing device for rock wave velocity test
Technical Field
The utility model relates to a rock mass fixing device of rock mass wave velocity test belongs to the reconnaissance technical field among the geotechnical engineering.
Background
The rock wave speed test usually is that the tester holds the acoustic wave appearance transducer by hand, paints couplant such as butter in transducer or rock both sides, and the artificial pressure application makes transducer and rock coupling, nevertheless because different people or one person's application of force are not of uniform size, the coupling effect difference is also more obvious, and often rock and transducer can't guarantee to become a straight line, the accuracy of direct influence test result.
Disclosure of Invention
The utility model discloses to the problem that above-mentioned exists and design and provide a rock fixing device of rock mass wave speed test, its purpose is when carrying out the test of rock mass wave speed, guarantees that rock mass and transducer laminating closely and become a straight line, does not receive artificial influence, improves the accuracy of rock mass wave speed test achievement.
The purpose of the utility model is realized through the following technical scheme:
this kind of rock fixing device of rock wave speed test includes a base 8, central point at base 8 puts and sets up a rock cushion cap 1, rock cushion cap 1 is installed on base 8 through cushion cap post 5, respectively set up a solid fixed ring 2 of transducer in the both sides of cushion cap post 5 and be used for fixed sound wave appearance transducer, solid fixed ring 2's of transducer bottom is passed through solid fixed ring base 7 of transducer and is installed on the slip track 4 of base 8 upper surface, make solid fixed ring 2 of transducer slide along 8 length direction of base, the axis of two solid fixed ring 2 of transducer is on same straight line.
Further, the bottom of the transducer fixing ring base 7 is fixedly connected with one end of an adjusting screw rod 3, the other end of the adjusting screw rod 3 is connected with an adjusting nut 6 fixed on the base 8, and the transducer fixing ring 2 is driven to move on the sliding rail 4 and apply force to the rock mass placed on the rock mass bearing platform 1 by rotating the adjusting nut 6.
Further, the transducer fixing ring 2 is composed of an upper half ring and a lower half ring and can be split.
Furthermore, sponge strips are pasted on the inner sides of the upper half ring and the lower half ring of the transducer fixing ring 2 to increase friction force.
Further, the height of the bearing platform column 5 connecting the rock bearing platform 1 and the base 8 is adjustable, so that the central line of the rock on the rock bearing platform 1 and the central axis of the transducer fixing ring 2 can be on the same straight line.
Further, a hole with built-in threads is processed at the bottom of the transducer fixing ring base 7 and is connected with the adjusting screw rod 3.
The rock fixing device for testing the wave velocity of the rock has the characteristics and solves the engineering problems as follows:
firstly, when a tester holds the test by hand, the rock and the axis of the transducer cannot be ensured to be in a straight line, the distance can be increased when sound waves are transmitted, and the test result is greatly influenced, and the rock bearing platform 1 and the bearing platform column 5 with adjustable height of the device can ensure that the rock is horizontally placed and the axis of the rock and the axis of the transducer are in a straight line, so that the test precision is improved;
secondly, force application is different when a tester holds the test, the rock mass and the transducer are not tightly coupled easily, and a larger middle gap is reserved;
thirdly, the rock fixing device for rock wave velocity testing can reduce human errors in rock sound wave testing, improve testing precision and have good technical and economic benefits.
