Application method of portal frame type PE pipe sleeve joint installation unit

Abstract

The invention discloses an application method of a portal frame type PE pipe sleeve joint installation unit. The portal frame type PE pipe sleeve joint installation unit comprises a rotary working table, a portal frame mechanical arm, a PE pipe sleeve joint installation manipulator and a PE pipe sleeve joint installation electronic control mechanism. The portal frame mechanical arm is of a portalframe structure fixedly installed on the ground, and the geometric center of the portal frame structure coincide with that of the rotary working table. The PE pipe sleeve joint installation manipulator is installed at the bottom end of a tail link of the mechanical arm and comprises a PE pipe end clamping sleeve joint installation part II and a PE pipe end heating part II. The portal frame type PEpipe sleeve joint installation unit is an automatic unit. A conical electric heating assembly is used for electrically heating the interior of the PE pipe end. The risk that the PE pipe end gets ageing too early can be greatly reduced. The labor intensity of operators can be greatly reduced. The installation efficiency can be improved. The portal frame type PE pipe sleeve joint installation unitis particularly suitable for installation of big-diameter and large-wall-thickness PE pipes for large and medium-sized reel jet-irrigating machines.

Description

technical field [0001] The invention relates to a method for using an auxiliary installation unit for a reel sprinkler irrigation machine, in particular to a method for using a gantry-type PE pipe socket installation unit suitable for installing PE pipes on a reel sprinkler irrigation machine for a PE pipe installation system The invention belongs to the technical field of reel sprinkler irrigation machines. Background technique [0002] Sprinkler irrigation is an irrigation method that uses special equipment such as nozzles to spray pressurized water into the air to form water droplets that fall to the ground sprinkler surface and crop surface. [0003] The reel sprinkler irrigation machine can irrigate a large area of ​​farmland, and can also control the amount of water sprayed according to the nozzle to meet the different requirements of users for the amount of sprinkler water. It is the sprinkler irrigation equipment usually selected for water-saving irrigation of farmla...

AI Technical Summary

Problems solved by technology

For large and medium-sized reel sprinkler irrigation machines, the nominal pressure of the PE pipe is usually 0.63-1.6MPa, the outer diameter is usually 65-250mm, the wall thickness of the pipe is usually 4.2-22.7mm, and the weight is relatively large. When installing the PE pipe, the end of the PE pipe is usually heated and softened before being manually socketed. The heating method is usually flame heating or hot oil heating, which is not only labor-intensive, long installation period, and low installation efficiency. Moreover, the way of flame heating or hot oil heating usually damages the outer surface of the end of the PE pipe, which in turn causes the risk of premature aging at the end of the PE pipe, which will reduce the overall quality of the reel sprinkler.
