Abstract
The utility model relates to a continuous oil pipe guiding device, in particular to a device for bending an oil pipe and introducing an injection head for a continuous string coiled tubing unit. The device mainly comprises an arc-shaped framework, a roller and an adjusting rod assembly and is characterized in that a pull rod is arranged in the position of a chord on the inner side of the arc-shaped framework, the roller adopts an ultrahigh molecular weight polyethylene material, and simultaneously, a plurality of pedals are arranged on a fixed support. The problem of potential safety hazard due to out of safety protection during the frequent position replacement of the hanging hook of the safety belt when the operators work on the continuous oil pipe guiding device back and forth is solved; and by adopting the ultrahigh molecular weight polyethylene material, not only does reduce the wear to the continuous pipe, simultaneously, but also the self-lubricating bearing endows the continuous oil pipe guiding device the characteristics of light weight, high wear resistance and self lubrication.
Description
Technical field:
The utility model relates to a kind of tubing bending of coild tubing unit and introduces the device of injection head.
Background technology:
Coild tubing unit has advantages such as operating cost is low, easy accessibility and is developed rapidly because of being applied to drilling well, completion, formation testing gas testing, oil recovery gas production, well workover and collection transporting operation.Coild tubing unit mainly by: coiled tubing, oil pipe cylinder, injection head, coiled tubing gatherer, coil tubing reel etc. are formed.
Domestic and international existing coiled tubing gatherer all adopts the framework that is arc at present.Arc framework by two cambered plates be connected little rectangular tube and form, all there is a fixed support chord length position of every cambered plate, arc framework is terminal inboardly to have a movable support frame near fixed support, arc framework has many places safety belt link along the camber line inboard; The two inner distribution of cambered plate many places metal rollers, bearing is equipped with in the inner both sides of roller, and bearing adopts the lubricating system of grease nipple filling butter.Some problems below such structure exists:
Because the coiled tubing gatherer is installed on the coiled tubing injection head, apart from high about 5 meters of ground, operating personnel need walk up and down in the high-altitude during operation, at this moment operating personnel just need take off safety belt from a link, the position of going to another place's link then hangs up safety belt again, operating personnel have broken away from protection when changing link, therefore produced serious potential safety hazard; Because roller adopts metal material, when coiled tubing moved on the coiled tubing gatherer, the wearing and tearing of coiled tubing had been quickened in the friction between roller and the coiled tubing, influenced the life-span of coiled tubing on the other hand; Bearing on last all rollers of this device all adopts the lubricating system of grease nipple filling butter, makes its maintaining extremely inconvenient.
Summary of the invention:
The purpose of this utility model is: a kind of handling safety, easily maintenance are provided, can reduce the coiled tubing gatherer that coiled tubing weares and teares.
The utility model is to realize above-mentioned purpose by following technical solution: the utility model coiled tubing gatherer comprises arc framework, roller, adjusting rod assembly etc., it is characterized in that: be provided with pull bar in the inboard chord length of arc framework position, described roller adopts the ultra high molecular polyethylene material of high abrasion and self-lubricating, and bearing adopts has bearing non-maintaining, self-lubricating.As further improvement, a plurality of pedals are set on fixed support.
During work high above the ground, operating personnel hang over safety belt on the pull bar, and on the coiled tubing gatherer back and forth during operation, safety belt just slidably reciprocates along with operating personnel's change in location, avoids frequent getting safety belt then.
Beneficial effect:
1. the pull bar that is provided with of coiled tubing gatherer by the fixing safety belt of bar on the throne, slidably reciprocates safety belt on pull bar, not only made things convenient for but also safety.
2. roller adopts superhigh molecular weight polyethylene material, have that material is light, high abrasion, self-lubricating property, make coiled tubing the time by the coiled tubing gatherer, reduced wearing and tearing, increase the application life of coiled tubing, also alleviated the weight of coiled tubing gatherer simultaneously.
3. adopt novel bearing non-maintaining, self-lubricating, need not alleviate operation intensity specially to its maintaining.
4. the many places pedal is set on fixed support, makes operating personnel that the step of walking and standing be arranged, operating personnel have guaranteed job safety again in convenient exerting oneself in operation process like this.
Description of drawings:
Fig. 1 is the front view of coiled tubing gatherer.
Fig. 2 is the vertical view of coiled tubing gatherer.
Fig. 3 is a coiled tubing gatherer A place partial enlarged drawing
The specific embodiment:
In conjunction with the accompanying drawings to this practical being further described.Referring to accompanying drawing 1, the coiled tubing gatherer connects into arc framework by the cambered plate 1 and the rectangular tube 12 of the band fixed support of two symmetries, in the inboard of arc framework junction plate 18 is arranged, and on this junction plate 18 pull bar 4 is arranged, this pull bar 4 be in cover plate assembly 3 under.In the arc framework outside, some rollers 19 that distribute between two cambered plates, and be fixed on the cambered plate framework by bearing pin 17, axle sleeve 20, bearing 16 is equipped with in roller 19 inner both sides, there is circlip for shaft 21 axle sleeve 20 both sides, are used to limit moving horizontally of bearing 20.Bearing 16 adopts self-lubricating, non-maintaining bearing.Roller 19 adopts the ultra high molecular polyethylene material.
In the coiled tubing operation process, when coiled tubing passes through this gatherer, make coiled tubing according to the arciform distortion of this gatherer and by arc orbiting motion, need 3 place's cover plate assemblies 3 shown in the figure are closed, so after operating personnel hang over safety belt on the pull bar 4, safety belt just can slidably reciprocate on pull bar, very convenient and safety during operation.As further improvement, on the fixed support of the both sides of cambered plate 1, pedal 5 is housed, operating personnel just can step down on the pedal 5 and walk up and down and stand when opening and closing cover plate assembly 3, and are both firmly convenient in operation process, can realize safety work again.
The utility model is not limited to above-mentioned embodiment, no matter do any variation on its shape or structure, the mode of every pull bar class comes the structure of hanging safety belt all to drop within the protection domain of the present utility model.
Claims (3)
1. a coiled tubing gatherer comprises segmental support framework, roller, bearing, adjusting rod assembly etc., it is characterized in that: be provided with pull bar in the inboard chord length of segmental support framework position.
2. a kind of coiled tubing gatherer according to claim 1, described roller adopts the ultra high molecular polyethylene material, and described bearing adopts has bearing non-maintaining, self-lubricating.
