Abstract
The utility model discloses a scale for measuring an internal diameter of a pipeline. The scale comprises a telescopic section, and one, two or more circular standard extension rods with fixed length. The telescopic section comprises a circular case with a central circular hole, a circular scale, a spring and a bottom spring base. The front end of the circular scale is in clamp connection with a ball, and the rear end is provided with a top spring base. The front end of the case is provided with an outlet that matches with the circular scale. The circular scale and the top spring base are arranged inside the case, with the circular scale being beyond the outlet of the case. The front end of the bottom spring base is fixed at the rear end of the case. The spring is disposed in the case, with front and rear ends thereof abutting on the top spring base and the bottom spring base, respectively. All the standard extension rods are fixed together in order, wherein the front end of the front standard extension rod is fixed to the rear end of the bottom spring base, and the rear end of the rear standard extension rod is in clamp connection with another ball. The scale of the utility model satisfies the requirement of measuring internal diameters of pipes with different diameters, in a direct-reading manner with few errors, up to the national standard on pipe internal-diameter measurement. In addition, the scale, which is quite low in cost, is convenient to carry and operate and is not easy to damage.
Description
Technical field
The utility model relates to a kind of internal diameter of the pipeline survey instrument, relates in particular to a kind of PCCP pipe internal diameter survey instrument.
Background technology
After PCCP pipe production completes, generally adopt micrometer inside caliper to measure pipe internal diameter and bell and spigot ovality at present.Micrometer inside caliper is comprised of micrometer head and extension bar, because micrometer head armrest is moving, turns varying dimensions, inconvenient operation, and reading is not directly perceived, fragile in high-frequency service condition.And micrometer inside caliper acquisition price is higher.
Summary of the invention
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, and a kind of measurement needs that can meet different tube diameters tubing are provided, and error is little, be easy to carry, easy to operate, reading is directly perceived, not fragile, and the very low internal diameter of the pipeline surveyors' staff of cost.
For completing above-mentioned purpose, technical solution of the present utility model is: a kind of internal diameter of the pipeline surveyors' staff, and it comprises the circular standard extension bar of telescopic joint and a joint, two joints or more piece regular length; Telescopic joint includes the circular shell of center hole, with circular scale, spring and the spring pedestal of indicating the exact scale of telescopic joint length; The front end of scale is connected with ball, the rear end spring footstock that portals slightly thick than housing that is integrated or is fixed as one; Housing front end has and portalling that scale matches, and spring footstock and spring pedestal and housing center hole match; Scale and spring footstock are placed in housing, and scale leans out housing and portals; Spring pedestal front end is fixed on outer casing back; Spring is placed in housing, and its front and back ends withstands on respectively on spring footstock and spring pedestal, and each standard extension bar is sequentially fixed together, and the front end of the standard extension bar of its front end is fixed on the rear end of spring pedestal, and the rear end of end standard extension bar is connected with another ball.
Spring pedestal front end screw thread described above is fixed on housing rear end, and each standard extension bar order screw thread is fixed together, and the front end screw thread of the standard extension bar of front end is fixed on spring pedestal rear end.
Housing described above forms by round jacket with the fixing cutting ferrule of round jacket screw thread; Spring footstock and spring pedestal and round jacket center hole match, and cutting ferrule front end has and portalling that scale matches.
While measuring pipe internal diameter, first according to the large young pathbreaker's telescopic joint of pipe diameter, end standard extension bar and the standard extension bar that wherein needs, be assembled into the survey instrument that length is slightly larger than pipe internal diameter, the hand-held survey instrument of survey crew enters in the middle of tubing, by survey instrument along tubing radially, making survey instrument two ends ball withstand pipe material inner wall slides, find out minimum dimension, the length of adding each standard extension bar is tubing hoop internal diameter.The utility model can meet the inner diameter measurement needs of different tube diameters tubing, and reading is directly perceived, and error is little, can reach pipe internal diameter and measure national standard; It is easy to carry, easy to operate, not fragile, and cost is very cheap.It,, at pipe internal diameter hoop with in axially measuring, does not damage concrete surface, is easy to put into and take out, and small volume, recycles rate higher.It is not only suitable for the measurement of PCCP pipe internal diameter, is also suitable for the measurement of other all pipe internal diameters.
