DETAILED DESCRIPTION

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] Embodiment 1:

[0022] This embodiment provides an anchor cable grouting pipe distance measuring mechanism, such as Figure 1 , Figure 4As shown, it includes a guide tube 1, a grouting tube 2, a measuring wheel 3 and a sensor 4. The grouting tube 2 is slidably arranged on the guide tube 1. The measuring wheel 3 is used to rotate with the movement of the grouting tube 2. The sensor 4 is used to detect the number of rotations of the measuring wheel 3 and then convert it into the movement length of the grouting tube 2. The measuring wheel 3 abuts against the grouting tube 2, and the up and down movement of the grouting tube 2 drives the measuring wheel 3 to rotate through friction. The movement of the grouting tube 2 is driven by external power. In this embodiment, the grouting tube 2 is driven by the grouting tube feeding mechanism 21.

[0023] The grouting pipe 2 is passed through the guide pipe 1, so that the movement of the grouting pipe 2 in the guide pipe 1 is stable. The measuring wheel 3 rotates following the movement of the grouting pipe 2, that is, the rotation distance of the measuring wheel 3 is the movement length of the grouting pipe 2. The sensor 4 is used to detect the rotation distance of the measuring wheel 3 and then obtain the movement length of the grouting pipe 2, which can realize the length measurement of the bidirectional movement of the grouting pipe 2 in the forward direction and the backward direction.

[0024] In order to ensure reliable detection, the measuring wheel 3 is provided with grooves 5 evenly distributed around the center, and the detection path of the sensor 4 intersects with the rotation path of the grooves 5, which can ensure that the sensor 4 can detect the distance change on the measuring wheel 3. In this embodiment, the grooves 5 are located on the front of the measuring wheel 3, and the measuring direction of the sensor 4 is perpendicular to the front of the measuring wheel 3. The sensor 4 calculates the rotation distance of the measuring wheel 3 by detecting the number of changes between the grooves 5 on the measuring wheel 3 and the plane, and then obtains the movement length of the grouting pipe 2.

[0025] For reliable installation, a sensor support 6 is provided on the guide tube 1 , one side of the sensor support 6 is fixedly connected to the guide tube 1 , and the other side is detachably connected to the sensor 4 , so as to facilitate maintenance and replacement of the sensor 4 .

The sensor 4 is inserted into the mounting tube 8; a nylon protective cover 9 is provided between the head of the sensor 4 and the mounting tube 8. The design of the mounting tube 8 facilitates the installation of the sensor 4 and has a good protective effect on the sensor 4; the nylon protective cover 9 not only plays a protective role, but also does not affect the detection of the sensor 4.

[0028] In order to ensure reliable rotation of the measuring wheel 3, a notch 10 is provided on the guide tube 1, and the measuring wheel 3 abuts against the grouting pipe 2 through the notch 10. The design of the notch 10 enables the measuring wheel 3 to contact the grouting pipe 2 in the guide tube 1, and the grouting pipe 2 in the guide tube 1 moves stably, thereby making the measurement result accurate.

[0029] For reliable installation, a measuring wheel support 11 is provided on the guide tube 1 . One side of the measuring wheel support 11 is fixedly connected to the guide tube 1 , and the other side is detachably connected to the measuring wheel 3 , so as to facilitate maintenance and replacement of the measuring wheel 3 .

One side of the second fixing plate 12 is fixedly connected to the guide tube 1, and the other side is detachably connected to the third fixing plate 13. The measuring wheel 3 is rotatably connected to the third fixing plate 13. In this embodiment, a connecting plate 17 is provided between the first fixing plate 7 and the second fixing plate 12. Both sides of the connecting plate 17 are respectively connected to the first fixing plate 7 and the second fixing plate 12, so that the three are integrated into a whole with high structural strength; a fixing tube 18 is provided on the third fixing plate 13, and the measuring wheel 3 is rotatably connected to the fixing tube 18 through a supporting shaft 19; a rolling bearing 20 is provided between the supporting shaft 19 and the fixing tube 18.

[0031] In order to ensure reliable rotation of the measuring wheel 3, a shock absorbing member 14 is provided between the second fixing plate 12 and the third fixing plate 13. The shock absorbing member 14 is used for buffering when the grouting pipe 2 is deformed or unevenly caused to cause vibration, so as to ensure reliable abutment between the measuring wheel 3 and the grouting pipe 2, thereby making the rotation data of the measuring wheel 3 reliable; specifically, the shock absorbing member 14 is a rubber shock absorbing block, and the two sides of the rubber shock absorbing block are respectively abutted against the second fixing plate 12 and the third fixing plate 13.
