Pipe core skid resistance anchoring device for vertical wire wrapping machine for prestressed concrete cylinder pipe

Abstract

The invention discloses a pipe core skid resistance anchoring device for a vertical wire wrapping machine for a prestressed concrete cylinder pipe. The anchoring device consists of an anchoring device base and an anchoring block; the anchoring device base is fixedly arranged on a base of a pipe core positioning wheel of a rotating platform of the wire wrapping machine; the anchoring block is embedded into the anchoring device base; a plurality of tooth sockets used for embedding a prestressed wire are evenly formed in the anchoring block. According to the anchoring device disclosed by the invention, relative slip generated between a pipe core and the rotating platform when wire wrapping is performed on the pipe core of the prestressed concrete cylinder pipe can be prevented, so that the stability of stress during wire wrapping is ensured, the quality of the prestressed concrete cylinder pipe is enhanced, and the engineering hidden danger is eliminated.

Description

Technical field: [0001] The invention belongs to the category of mechanical structures, and in particular relates to an anti-skid anchor for the tube core of a vertical prestressed steel cylinder concrete tube wire wrapping machine. Background technique: [0002] Prestressed Concrete Cylinder Pipe (PCCP for short) is made by winding a hoop prestressed steel wire on a high-strength concrete tube core with a steel cylinder, and then spraying a dense cement mortar protective layer on it. of water pipes. It is a composite pipe made of thin steel plate, high-strength steel wire and concrete ( figure 1 ). Its production process mainly has the following steps: [0003] 1. Processing of socket and socket joints: PCCP joints adopt the connection method of socket and socket. The socket steel ring and socket steel ring are important parts for pipe connection and water sealing. After steel plate cutting, ring welding, and socket steel ring pressing Forming, socket and socket steel r...

Problems solved by technology

However, with the continuous increase of the wire winding stress of the die, the situation that the pressure plate cannot hold down the die often occurs when the wire is wound, that is, the platform rotates and the die does not rotate or rotates slowly, resulting in the prestress cannot be applied or Larger prestress loss will eventually cause the pipeline to lose its pressure resistance
