Description
Technical field
The present invention relates to a kind of measurement apparatus, PCCP pipe diameter measuring devices are specifically referred to.
Background technology
PCCP pipes are the strong concrete tube core winding compressor wires with steel cylinder, are sprayed with cement mortar protective course,
Welded together with steel cylinder using steel bell and spigot, the fluted flexible joint that slidingtype cushion rubber is formd with cushion rubber of bell and spigot is
The composite construction that steel plate, concrete, high tensile steel wire and cement mortar different materials are constituted, with steel and the respective spy of concrete
Property.Prestressed concrete cylinder pipe has compound structure, bear that interior external pressure is higher, joint tighness is good, shock resistance is strong, tie up
The characteristic such as shield is convenient, it is of interest by engineering circles, be widely used in long interval water conveying tunnel, pressure inverted-siphon, urban water supply engineering,
Industry pressure water conveyer pipeline, power plant cycle Hydraulic Projects sewer pipe, pressure blowdown main etc..Compared with conventional tubing, PCCP tools
Have applied widely, economic life length, anti-seismic performance are good, easy for installation, operation expenditure is low, the advantages of substantially water-tight.
At present after the completion of the production of PCCP pipelines, generally pipe internal diameter and bell and spigot ovality are entered using inside micrometer
Row measurement.Inside micrometer is made up of micrometer head and extension bar, is turned because micrometer head armrest is dynamic and is carried out varying dimensions, operation is not square
Just, reading is not directly perceived, fragile in high-frequency service condition.And inside micrometer acquisition price is higher.
The content of the invention
It is an object of the invention to provide PCCP pipe diameter measuring devices, the convenient quick measurement to internal diameter of the pipeline reduces simultaneously
Measurement error, and then reach purpose that is efficient, accurately measuring.
The purpose of the present invention is achieved through the following technical solutions：
PCCP pipe diameter measuring devices, including fixed cylinder and the position-limiting drum in fixed cylinder, in the position-limiting drum
Lower rotation is provided with steel ball, and the steel ball locally protrudes from the bottom of fixed cylinder, and spring is provided with fixed cylinder, is also wrapped
The movable block and fixed seat for the truncated cone-shaped being connected with the movable end of the spring are included, the movable block passes through graduated scale and fixed seat
Connection, is provided with multiple projections, the inwall of the fixed cylinder to offer on the outer wall of movable block and multiple is engaged with raised
