Problems solved by technology

[0006] However, when this cylinder inner diameter measuring device measures the inner diameter of a cylinder, a measuring head is installed in the cylinder, an operation member is connected to the measuring head, and the left and right cylinders are fastened with bolts, and the cylinder head is mounted on the cylinder. On one cylinder, a cylinder inner diameter measuring device is attached to the head of the cylinder, so much labor and time are required for preparation, and it is difficult to measure the inner diameter of the cylinder simply.
[0007] In addition, in the conventional cylinder inner diameter measuring device, the wiring connected to the measuring piece is drawn out of the device through the tubular operating piece, so there is a problem of distributing when the operating piece is taken and sent along the axis of the cylinder. When the thread is slack and becomes U-shaped, which hinders the operation

Abstract

An apparatus for measuring diameter of cylinder in reciprocating internal combustion engine is provided to easily, safely, and accurately measure the diameter of cylinder. An apparatus(1) for measuring diameter of cylinder in reciprocating internal combustion engine comprises a guide(2), support(3), support rod(4), and length measuring machine(5). The guide is placed on the axis center of cylinder. The support supports the guide. The support rod of vertical length is connected to the guide. The length measuring device is placed to cross the support rod and comprises main body of measuring device and displace converter. The main body of the length measuring device has rod form.

Description

technical field [0001] The present invention relates to a cylinder diameter measuring device of a reciprocating internal combustion engine, which measures the cylinder diameter of a relatively large internal combustion engine such as a crosshead internal combustion engine. Background technique [0002] In a relatively large internal combustion engine such as a crosshead type internal combustion engine, when the wear of the cylinder liner exceeds a certain limit, the cylinder liner must be replaced. In addition, when the wear per unit time is large, it is necessary to perform processing such as increasing the amount of lubricating oil supplied to the cylinder to prevent wear. [0003] Therefore, in a relatively large internal combustion engine such as a crosshead internal combustion engine, it is necessary to measure the diameter of the cylinder in order to grasp the wear of the cylinder liner and perform appropriate maintenance work. [0004] The crosshead type internal com...
