Description

Technical Field

[0001] The utility model belongs to the technical field of pile foundation detection, and specifically relates to a novel pile foundation collapse detection device. Background Art

[0002] After the pile foundation is poured, a sonic detection pipe channel is generally reserved at the top of the pile. The transducer is placed at the bottom of the sonic detection pipe, and the transducer is slowly lifted by pulling the connecting wire. During the lifting process, the transducer emits sound waves to detect the pile foundation. The detected waveform image data will be presented in real time on the main body of the ultrasonic detector, which is used to detect the internal collapse of the pile foundation. At present, when lifting the transducer, the power connection line is generally connected to the electronic distance meter, and the distance meter is driven to rotate by manual pulling, so as to obtain the real-time distance of the transducer lifting. Transducer detection is generally carried out through multi-channel detection. The most common one is four transducers. It is troublesome and laborious to pull the wire manually, and the manual pulling of the wire is not uniform enough. When the four power connection lines are pulled manually, there will be a problem of asynchrony causing the transducer to be lifted and misaligned. Utility Model Content

The transducer detection is generally carried out through multi-channel detection, and the most common one is generally four transducers. It is troublesome and laborious to pull the wire manually, and the manual pulling of the wire is not uniform. When the four power connection wires are pulled manually, there will be a synchronization problem that causes the transducer lifting to be misaligned.

[0004] To achieve the above purpose, the utility model adopts the following technical solution: a novel pile foundation collapse detection device, comprising a tripod, a main body block is arranged on the upper side of the tripod, a rotating groove is opened on the upper side of the main body block, a rotating roller is rotatably arranged on the inner side of the rotating groove, a rotation counter is arranged on one side of the main body block, the output end of the rotating roller is rotatably connected to the rotation counter, wire clamping grooves are equidistantly opened on the outer side of the rotating roller, and the number of the wire clamping grooves is four, a pressure cover is rotatably arranged on the upper side of the main body block, and a wire pressing roller is symmetrically rotatably arranged on the lower side of the pressure cover, the wire pressing rollers are arranged on both sides of the rotating roller, and the lower side of the wire pressing roller is in contact with the outer side of the rotating roller.

When the wire pulling ring rotates, the power connection wire is pulled toward the side away from the main body block through static friction, and the power connection wire continues to pass through the lower side of the wire pulling ring and the wire pressing rod. Under the pulling of the wire pulling ring, the power connection wire drives the rotating roller to rotate, and the rotation counter calculates the number of rotations of the rotating roller for distance measurement. There is no need for manual wire pulling, which is more labor-saving, and the four wire pulling rings rotate synchronously, and the pulling of the power connection wire is synchronous and uniform, which prevents the problem of transducer lifting and misalignment due to asynchronism.
