Problems solved by technology

The inner diameter micrometer is composed of a micrometer head and an extension rod. Since the micrometer head is manually twisted to change the size, the operation is inconvenient, the reading is not intuitive, and it is easily damaged in high-frequency use.
And the purchase price of inner diameter micrometer is higher

Abstract

The invention discloses a PCCP pipe diameter measuring device. The PCCP pipe diameter measuring device comprises a fixed cylinder, a limiting cylinder which is mounted in the fixed cylinder, a truncated cone-shaped moving block and a fixed seat; a steel ball is rotatably arranged at the bottom of the limiting cylinder; the steel ball is partially protruded from the bottom end of the fixed cylinder; a spring is mounted in the fixed cylinder; the moving block is connected with the free end of the spring and is connected with the fixed seat through a graduated scale; a plurality of bulges are formed on the outer wall of the moving block; a plurality of grooves which are matched with the bulges are formed in the inner wall of the fixed cylinder; a rolling ball is rotatably arranged on the upper surface of the fixed seat. When the axis of the fixed cylinder is overlapped with the straight line in which the diameter of a pipeline is positioned, the data on the graduated scale is read, and is the displacement generated by the linear movement of the moving block; the inside diameter of the pipeline can be obtained by calculating, namely subtracting the linear displacement of the moving block from the linear distance between the bottom end of the steel ball and the top end of the rolling ball.

Description

technical field [0001] The invention relates to a measuring device, in particular to a PCCP pipe diameter measuring device. Background technique [0002] PCCP pipe is a high-strength concrete tube core with a steel cylinder wound with prestressed steel wire, sprayed with a cement mortar protective layer, and adopts a steel socket, which is welded together with the steel cylinder. The socket has grooves and rubber rings to form a sliding type. The flexible joint of the rubber ring is a composite structure composed of steel plate, concrete, high-strength steel wire and cement mortar, and has the respective characteristics of steel and concrete. Prestressed steel cylinder concrete pipe has the characteristics of composite structure, high internal and external pressure, good joint sealing, strong earthquake resistance, and convenient maintenance. Urban water supply projects, industrial pressurized water pipelines, sewer pipes of power plant circulating water projects, pressure ...
