Detailed Description

The technical scheme of the utility model is described in detail below through the drawings, but the protection scope of the utility model is not limited to the embodiments.

Referring to fig. 1 and 2, a device for measuring the diameter of an expanded section of a capsule-type expanded anchor rod comprises a main rod body 1 and a movable rod body 2 which is sleeved on the main rod body 1 in a sliding manner, wherein a first rope tying ring 3 is arranged at the top end of the main rod body 1 and is used for being connected with a main rope, an upper connecting mechanism 4 is arranged at the part, close to the top end, of the movable rod body 2, a lower connecting mechanism 5 is arranged at the bottom of the main rod body 1, three upper chords 6 are hinged on the upper connecting mechanism 4, three lower chords 7 are hinged on the lower connecting mechanism 5, the three upper chords 6 and the lower chords 7 are respectively and correspondingly connected in a rotating manner, a second rope tying ring 8 is arranged on the upper connecting mechanism 4, and a balancing weight 9 is arranged on the movable rod body 2 and is used for increasing the dead weight of the movable rod body 2.

In the utility model, the upper connecting mechanism 4 and the lower connecting mechanism 5 have the same structure, the upper connecting mechanism 4 comprises a connecting disc 41 sleeved on the movable rod body 2, three grooves for inserting the upper chord 6 are formed in the connecting disc 41, and the rotation of the upper chord 6 relative to the connecting disc 41 is completed through a rotating shaft 42 penetrating the grooves and being inserted into the upper chord 6.

The working principle of the utility model is as follows:

1. and the aperture measurement of the body expansion section can be carried out after the construction of the body expansion section of the capsule-type body expansion anchor rod is completed.

2. Two measuring ropes are prepared on site, the main measuring rope is firmly connected with the first rope tying ring 3, the auxiliary measuring rope is firmly connected with the second rope tying ring 8, the upper chord 6 and the lower chord 7 are kept parallel to the main rod body 1, and the free ends of the main measuring rope and the auxiliary measuring rope are flush.

3. The measuring device is put into the drill hole from the center part of the hole diameter until reaching the bottom of the hole. At this time, the measuring device is lifted slightly, so that the measuring rope is straightened and is in a stretched state.
