Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution: a cylinder center measurement auxiliary equipment comprises a cylinder 1 and an auxiliary device 2 for measuring the cylinder 1.

Specifically, the auxiliary device 2 includes three columns 3, the bottom of the three columns 3 is formed with a fixed head 4, the fixed head 4 can be a sharp object, which is easy to insert into the ground, so that the columns 3 are kept in a vertical state, or can be a heavy object with certain gravity, the heavy object can be fixed at the bottom of the columns 3, or a hole can be formed in the center of the heavy object, so that the columns 3 are inserted into the hole, no matter in a fixed or inserted manner, the purpose is to keep the columns 3 in a vertical state, therefore, the telescopic structures 5 are movably connected between two adjacent columns 3, and the lengths of the three telescopic structures 5 are kept consistent after adjustment, at this time, the three telescopic structures 5 and the three columns 3 form an equilateral triangle, the three columns 3 are equivalent to three corners of the equilateral triangle, and the coordinates of the three corners can be simply measured, the telescopic structures 5 are equivalent to three sides of the equilateral triangle, the three sides are all tangent to the cylinder 1, and the center of the cylinder 1 is the center of the equilateral triangle, and the center coordinates of the cylinder 1 can be measured according to the known three angular coordinates, and such a measurement method can be known from the ruler drawing learned in the beginning and high, so that the detailed description is omitted for the common knowledge of the skilled person in the art.

Specifically, the telescopic structure 5 includes a fixed cylinder 51, a first fixed ring 52 is fixedly connected to one end of the fixed cylinder 51, the first fixed ring 52 is an elastic split ring, the inner side of the first fixed ring 52 is clamped with the outer side of one of the two adjacent upright posts 3, a telescopic rod 53 is slidably connected to the other end cavity of the fixed cylinder 51 far away from the first fixed ring 52, a limit bolt 54 is connected to the other end surface of the fixed cylinder 51 close to the telescopic rod 53 in a threaded manner, the limit bolt 54 penetrates into the fixed cylinder 51 and abuts against the outer wall of the telescopic rod 53, a scale 56 is arranged on the surface of the telescopic rod 53, the length of the telescopic rod 53 can be visually known conveniently, a second fixed ring 55 is fixedly connected to one end of the telescopic rod 53 far away from the fixed cylinder 51, the second fixed ring 55 is an elastic split ring, and the inner side of the second fixed ring 55 is clamped with. The telescopic structure 5 is respectively connected with the first fixing ring 52 and the second fixing ring 55 in a clamping and fixing mode through the upright column 3, so that the device can be conveniently detached and is convenient for field operation.
