Embodiment 1

[0037] An automatic traction system for a dam internal inertial navigation monitoring device, comprising a traction device 6, a hoisting device driven by a driving device to rotate is arranged in the traction device 6, a traction rope 3 bypasses the hoisting device, and the traction rope 3 is connected with the hoisting device along the The monitoring device 4 that the flexible detection tube 2 travels is connected;

[0038] Also comprise rotatable first guide wheel 7, traction rope 3 walks around first guide wheel 7, is provided with wrapping angle guide wheel 71 at the front and back of first guide wheel 7, to increase traction rope 3 in the first guide The wrap angle on the wheel 7, in this example, the wrap angle of the traction rope 3 on the first guide wheel 7 is greater than 180 °, thus the structure prevents the traction rope 3 from slipping on the first guide wheel 7, ensuring that the traction rope 3 Keep synchronization between the movement of the first guide wheel ...

Embodiment 2

[0041] The preferred solution is as figure 1 Among them, on the basis of Embodiment 1, the flexible detection tube 2 is arranged obliquely, the hoisting device is a reel 61 driven to rotate by the driving device, and the traction rope 3 is connected to the tail of the monitoring device 4. The head of the monitoring device 4 is connected with a weight 5 . The specific structure of the hoisting device is as follows: the servo motor 63 is connected with the reel 61 through a reducer 65, and the reducer includes a worm gear reducer, a gear reducer and a belt reducer, and one or more combinations thereof can be selected. Preferably, a damper 64 is also provided on the shaft of the reel 61 or the reducer, and a magnetic powder damper is selected in this example. When in use, the monitoring device 4 slides down along the flexible detection tube 2 by the weight of the weight 5 of about 5 kg and the weight of the monitoring device 4 itself, the traction rope 3 drives the first guide w...

Embodiment 3

[0043] On the basis of Example 1, such as figure 2 Among them, the hoisting device is a reel 61 driven to rotate by a driving device. The specific structure of the hoisting device is: the servo motor 63 is connected to the reel 61 through a reducer 65, and the reducer includes a worm gear reducer, a gear reducer and One or more combinations of belt reducers can be selected. Preferably, a damper 64 is also provided on the shaft of the reel 61 or the reducer, and a magnetic powder damper is selected in this example.

[0044] There are two groups of hoisting devices, the traction rope 3 of one group of hoisting devices is connected to the tail of the monitoring device 4, and the traction rope 3 of the other group of hoisting devices bypasses the tube bottom guide wheel 62 at the bottom of the flexible detection tube 2 Connect with the head of the monitoring device 4. In a preferred solution, the first guide wheels 7 are correspondingly divided into two groups, so as to obtain mo...

Abstract

The invention provides a dam interior inertial navigation monitoring device automatic traction system comprising a traction device. The traction device is internally provided with winding devices which are driven to rotate by a driving device. A traction rope is wound on the winding devices and is connected with a monitoring device which walks along a flexible test tube. The dam interior inertial navigation monitoring device automatic traction system also comprises rotatable first guiding wheels. The traction rope is wound on the first guiding wheels. A wrap angle guiding wheel is arranged at the front and back parts of the first guiding wheels so as to increase the wrap angle of the traction rope on the first guiding wheels. An absolute value photoelectric encoder is arranged on the first guiding wheels or the winding devices. According to the dam interior inertial navigation monitoring device automatic traction system, the position of the monitoring device in the flexible detection tube and walking speed can be accurately acquired by the arranged absolute value photoelectric encoders with cooperation of a PLC or a single-chip microcomputer.

Description

technical field [0001] The invention relates to the field of engineering surveying devices, in particular to an automatic traction system for a dam inner view inertial navigation monitoring device. The invention is suitable for the distributed monitoring of the deflection of the super-high concrete face rockfill dam face, the internal settlement of the dam body and the horizontal displacement, and can also be used for the distributed monitoring of the dam body settlement of super-high core wall rockfill dams, earth dams and other projects. Background technique [0002] With the development of dam engineering technology, the dam height of concrete face rockfill dams is gradually increasing. Since the beginning of the 21st century, a number of high concrete face rockfill dams with a dam height of 200m have been built successively in the world. While the height of the concrete face rockfill dam increases, the stress and deformation of the dam body and the operating state of the...
