Interspersed high density polyethylene pipe construction equipment in a kind of online pipeline

Technical field:

The utility model belongs to the special equipment in the interspersed bushing pipe operation in the online pipeline.

Technical background:

At present, in all parts of the country all have a large amount of oil transportations, gas transmission and sewage conduct, and seriously corroded if upgrade these pipelines, needs the excavation pipe trench, and not only engineering cost height, and long construction period also influences above ground structure and communal facility sometimes.If repair these pipelines, the construction equipment structure of the steel pipeline long-range lining high density polyethylene pipe that uses is undesirable at present, constructional difficulties, equipment heaviness, converting pipe are prone to and wander off, extremely roll over, and the caliber distortion is not easy to operate, the construction quality uncontrollable factor is more, and does not twine bushing pipe equipment.

Summary of the invention:

The utility model designs for addressing this problem just.High density polyethylene pipe former in this equipment is made up of base, portal frame, adjusting rod, briquetting roller, armful wheel etc.; The typing Stetch Wrapping Machine is made up of gear pulley, driving gear, variable-frequency motor, support roller, support, take-up strap roller etc., before bushing pipe interts, at first high density polyethylene pipe is become the U type by the high density polyethylene pipe former, then take-up strap is wrapped in equably on the high density polyethylene pipe that has become the U type with Stetch Wrapping Machine, utilize miscellaneous equipment will be out of shape internal lining pipe then and penetrate in spool and make it and restore, finish whole deep-penetration mission.The purpose of this utility model just provides interspersed high density polyethylene pipe construction equipment in a kind of online pipeline

The utility model be achieved in that the base [1] of high density polyethylene pipe former and fixedly portal frame [2] form a framework, adjusting rod [3], [4], [5] that can regulate angle are installed on portal frame [2], regulating rod bottom is hinge, slide slot is arranged on wedged block at top, according to high density polyethylene pipe distortion size, regulate 10 °～45 ° of rod regulation ranges.Briquetting roller [6] edge is a circular arc, and by Bearing Installation on base support [7], can up-down adjustment.Embracing wheel [8] for two is embracing on the wheel support [9] by bearing fixing, embrace wheel axis perpendicular to base plane, embracing wheel middle is symmetrical spill, embraces wheel relative distance and can regulate, its spill matches with the U-shaped internal lining pipe outer rim shape size of being processed, and makes the internal lining pipe cross section become U-shaped.The typing Stetch Wrapping Machine links to each other with the high density polyethylene pipe former, it is characterized in that: driving gear [11] and variable-frequency motor [12] connect and are fixed on that Stetch Wrapping Machine chassis [18] is gone up, support [14] and chassis [18] are fixed, support roller [13] is fixed on four jiaos up and down on Stetch Wrapping Machine support [14], gear pulley [10] is squeezed in the centre by eight support rollers [13], gear pulley [10] is connected with chain with driving gear [11], and there is driving gear [11] driven gear cylinder [10] to rotate together, take-up strap roller [15] is installed on gear pulley [10] edge, rotates with gear pulley.Variable-frequency motor [12] rotating speed is to decide according to distortion internal lining pipe hauling speed, makes take-up strap [16] uniform winding on U type internal lining pipe [17].

The utility model is in the long distance of line Pipe is interted the bushing pipe construction, because high density polyethylene pipe former structure advanced person is out of shape adjustable, and and then strained liner take-up strap is twined by the typing Stetch Wrapping Machine, make interspersed operation time saving and energy saving, operation is convenient, has improved workmanship.

Embodiment:

Now the utility model will be further described in conjunction with Figure of description.When adopting the utility model to carry out internal lining pipe when interting, the high density polyethylene pipe former by base [1] and fixedly portal frame [2] form a whole frame, adjusting rod [3], [4], [5] that can regulate angle are installed on portal frame, regulating rod bottom is hinge, slide slot is arranged on wedged block at top, according to high density polyethylene pipe distortion size, regulate 10 °～45 ° of rod regulation ranges; Briquetting roller [6] edge is a circular arc, and by Bearing Installation on base support [7], can up-down adjustment; Embrace wheel [8] for two, embracing on the wheel support [9], embrace wheel axis perpendicular to base plane by bearing fixing, embracing wheel middle is symmetrical spill, embracing wheel relative distance can regulate, and its spill matches with the U-shaped internal lining pipe outer rim shape size of being processed, and makes the internal lining pipe cross section become U-shaped.The typing Stetch Wrapping Machine links to each other with the high density polyethylene pipe former, driving gear [11] and the variable-frequency motor [12] of typing Stetch Wrapping Machine connects and is fixed on that Stetch Wrapping Machine chassis [18] is gone up, support [14] and chassis [18] are fixed, support roller [13] is fixed on four jiaos up and down on Stetch Wrapping Machine support [14], gear pulley [10] is squeezed in the centre by eight support rollers [13], gear pulley [10] is connected with chain with driving gear [11], and there is driving gear [11] driven gear cylinder [10] to rotate together, take-up strap roller [15] is installed on gear pulley [10] edge, rotates with gear pulley.Variable-frequency motor [12] rotating speed is to decide according to distortion internal lining pipe hauling speed, makes take-up strap [16] uniform winding on U type internal lining pipe [17].

The utility model is in the long distance of line Pipe is interted the bushing pipe construction, because high density polyethylene pipe former structure advanced person, be out of shape adjustable, and and then strained liner take-up strap is twined by the typing Stetch Wrapping Machine, utilizing miscellaneous equipment will be out of shape internal lining pipe then penetrates in spool and makes it and restore, bushing pipe and line Pipe inwall are tightly sticked together, play the corrosion-resistant purpose.The operation that interts is convenient, and time saving and energy saving, workmanship improves greatly.
