Please refer to Figures 1-5, an embodiment provided by the present utility model:

A tool for measuring the distance between capping blocks when assembling shield segments. It includes a measuring rod 1. The two ends of the measuring rod 1 are fixedly connected with clamping plates 2. The measuring rod 1 includes a main rod 11, and the inner surface of the main rod 11 is slidably connected with a clamping plate 2. A fixing nut 13 is fixedly connected to the surface of the auxiliary rod 12 and the main rod 11, and a locking bolt 14 is threadedly connected to the surface of the fixing nut 13. The clamping plate 2 includes a horizontal plate 21, and an adjusting screw is threadedly connected to the surface of the horizontal plate 21. 22. A movable plate 23 is fixedly connected to the surface of the adjusting screw 22. The measuring rod 1 can be telescoped to adjust the length to adapt to the distance between the two sets of segments. At the same time, the horizontal plate 21 and the movable plate 23 are connected in the same tube. On the edge of the segment, lock the position of the measuring rod 1 to measure the distance between the two sets of segments.

Furthermore, two sets of clamping plates 2 are provided. One set of clamping plates 2 is arranged at an end of the main pole 11 away from the auxiliary pole 12, and the other set of clamping plates 2 is arranged at an end of the auxiliary pole 12 away from the main pole 11. Since the auxiliary pole 11 is The rod 12 slides on the main rod 11 so that the two sets of clamping plates 2 can change the relative distance between them, so that both sets of clamping plates 2 are stuck on their respective segments.

Furthermore, the interior of the main rod 11 is hollow, and the hollow area of the main rod 11 is just the area where the auxiliary rod 12 slides. There is a circular hole on the surface of the main rod 11, and the fixing nut 13 is fixedly connected to the circular hole of the main rod 11. superior.

Further, the locking bolt 14 enters the interior of the main rod 11 through the fixed nut 13 and the circular hole of the main rod 11. The locking bolt 14 squeezes the auxiliary rod 12 on the inner surface of the main rod 11 and rotates and locks on the fixed nut 13. The bolt 14 and the locking bolt 14 are provided with a handle, which is convenient for workers to operate, and can adjust the squeezing degree of the auxiliary rod 12 by the locking bolt 14, thereby achieving the effect of fixing the auxiliary rod 12 inside the main rod 11.

Further, a vertical relationship is maintained between the horizontal plate 21 and the measuring rod 1, so that both sets of horizontal plates 21 can fit on the joint surfaces of the two sets of segments, and the horizontal plates 21 are fixedly connected to both sides of the measuring rod 1. Equivalently, a set of transverse plates 21 are fixedly connected to the surface of the main rod 11 , and a set of transverse plates 21 are fixedly connected to the surface of the auxiliary rod 12 .

Further, a notch is provided on one side of the horizontal plate 21, and threaded holes are provided on both sides of the notch of the horizontal plate 21.

Convenient for staff to operate.

Furthermore, the length of the movable plate 23 is shorter than the length of the notch of the horizontal plate 21, so that the movable plate 23 has a certain moving space to facilitate the rotation of the movable plate 23. The length of the adjusting screw 22 is greater than the length of the horizontal plate 21, and the adjusting screw 22 can At the same time, it rotates on the two sets of threaded holes, and the adjusting screw 22 drives the movable plate 23 to rotate at the gap of the horizontal plate 21, thereby changing the inclination angle of the movable plate 23 on the horizontal plate 21.

Working principle: Rotate the locking bolt 14 on the fixing nut 13 and loosen the auxiliary rod 12 so that the auxiliary rod 12 can slide on the inner surface of the main rod 11.
