Abstract
The utility model discloses a portable vernier gauge for measuring the abrasion quantity of a tunnel boring machine (TBM)/shield tunneling machine cutter. The portable vernier gauge comprises a main ruler and a vernier which is attached to the main ruler and can slide along the main ruler, wherein the vernier is provided with a measuring claw which is perpendicular to the vernier and a locking screw for positioning the vernier on the main ruler. The main ruler is provided with cutter standard size scales in at least one specification; the distances from the cutter standard size scales to the front end of the main ruler are equal to differences of the cutter ring radiuses and the cutter shaft radiuses of cutters in corresponding specifications; and the vernier is provided with graduation marks for indicating the cutter abrasion quantity. The portable vernier gauge can accurately measure the abrasion quantity of the tunnel boring machine (TBM)/shield tunneling machine cutter and is not affected by the thickness of the cutters.
Description
Technical field
The utility model relates to measurer, is specifically related to a kind of portable game scale of the TBM/ of measurement shield machine cutter abrasion amount.
Background technology
TBM or shield machine are the special engineering machinery of tunnel piercing, wherein, cutter is the critical component of driving, also be parts the most easy to wear and that lost efficacy, the wearing and tearing of cutter will directly affect quality and the progress of engineering, therefore, accurately grasp the wear extent of cutter, to rational boring parameter is set, planned replacing cutter plays conclusive effect.At present, generally measure the tool abrasion of TBM or shield machine with the splayed slide calliper rule, if but the thickness of cutter is excessive, and cause easily measurement inaccurate.Therefore, be necessary to develop a kind of measurer of energy Measurement accuracy tool abrasion.
The utility model content
The purpose of this utility model is to provide a kind of portable game scale of the TBM/ of measurement shield machine cutter abrasion amount, can accurately measure the wear extent of TBM/ shield machine cutter, and is not subjected to the impact of cutter thickness.
For reaching above-mentioned purpose, the portable game scale of the measurement TBM/ shield machine cutter abrasion amount that the utility model provides, comprising main scale and be attached to also can be along the vernier of main scale slip on the main scale, described vernier is provided with perpendicular measuring jaw, be equipped with on the described vernier vernier is positioned lock-screw on the main scale, its key is: described main scale is provided with the cutter standard size scale of at least a specification, described cutter standard size scale equals the poor of the cutter ring radius of corresponding specification cutter and cutter shaft radius apart from the distance of main scale front end, and described vernier is provided with the graduation apparatus that shows tool abrasion.
When described lock-screw locking, the lower end of this lock-screw and the upper surface of described main scale push against.
Be provided with altogether the cutter standard size scale of four kinds of specifications on the described main scale, the cutter of described four kinds of specifications is respectively 15.5 inches, 17 inches, 19 inches and 21 inches.
During measurement, the front end of main scale is against on the cutter shaft of cutter, then moving cursor, measuring jaw is pushed against on the cutter ring of cutter, rotate simultaneously this vernier scale, when the size reading on the vernier is maximum, tightens lock-screw vernier is positioned on the main scale, read the data on the vernier, these data are the wear extent of this cutter.
The beneficial effects of the utility model are: can measure accurately, intuitively the wear extent of TBM/ shield machine cutter by this vernier scale, and not be subjected to the impact of cutter thickness; And simple in structure, simple to operate, cost is low.
