Description
Technical field
The utility model belongs to petroleum machinery equipment technical field, relates to a kind of oil-well rig boring tower assembling bearing of variable aperture.
Background technology
Oil-well rig boring tower needs to carry out overall package in process of production, verifies its Design and manufacture, must be fixed in an assembling process to derrick.
Traditional fixed form is that the derrick of each model must design frock bearing supporting with it due to the aperture difference of derrick leg, this just need make frock bearings different in a large number, assemble with the derrick meeting different model, cause frock to overstock in a large number, cost sharply increases.
Utility model content
The purpose of this utility model is to provide a kind of oil-well rig boring tower assembling bearing of variable aperture, and solving frock bearing supporting in prior art, to there is model single, the problem of poor universality.
The technical scheme that the utility model adopts is, a kind of oil-well rig boring tower of variable aperture assembling bearing, comprises ear seat and a pair conversion sleeve, the aperture of the sleeve joint hole of ear seat and this be interference fits to the body outer diameter of conversion sleeve.
The oil-well rig boring tower assembling bearing of variable aperture of the present utility model, its feature is also:
Ear seat is welded-steel plate construction, and two ear seats are parallel to be welded on base plate, and each ear seat arranged outside has multiple gusset, and vertical two ear seats have coaxially with the sleeve joint hole of diameter, and the surrounding that ear seat is positioned at sleeve joint hole simultaneously has multiple screwed hole.
Conversion sleeve is multiple sizes of different model, and the body outer diameter basic size of all conversion sleeves is identical with the aperture basic size of ear seat sleeve joint hole, and the diameter basic size of the endoporus of conversion sleeve is identical with the installation aperture of dissimilar derrick leg; Have the bolt through-hole corresponding with the screwed hole of ear seat at the end face of flange of conversion sleeve, bolt through-hole is identical with the diameter basic size of screwed hole.
The beneficial effects of the utility model are, by changing different conversion sleeves, to change the endoporus of frock bearing, realizing the assembling of dissimilar oil-well rig boring tower, can not only ensure the smooth assembling of derrick, and be a set of multiplex.Have simple to operate, safe and reliable, versatility is good, operating efficiency is high, manufacturing cost is low, to personnel qualifications not high and can meet product quality require feature.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, structure of the present utility model is, comprises ear seat 1 and a pair conversion sleeve 2, the aperture of the sleeve joint hole 8 of ear seat 1 and this be interference fits to the body outer diameter of conversion sleeve 2,
With reference to Fig. 2, Fig. 3, ear seat 1 is welded-steel plate construction, parallelly on base plate be welded with two ear seats 1, each ear seat 1 arranged outside has multiple gusset 4, (level) vertical two ear seats 1 have coaxially with the sleeve joint hole 8 of diameter, the aperture basic size of sleeve joint hole 8 is a, and surrounding's (upper-lower position and or right position) that simultaneously ear seat 1 is positioned at sleeve joint hole 8 has multiple screwed hole 5;
With reference to Fig. 4, Fig. 5, conversion sleeve 2 is multiple sizes of different model, the body outer diameter basic size of all conversion sleeves 2 is identical with the aperture basic size of ear seat 1 sleeve joint hole 8 is a, and the diameter basic size of the endoporus 7 of conversion sleeve 2 is identical with the installation aperture of dissimilar derrick leg 3; Have the bolt through-hole 6 corresponding with the screwed hole 5 of ear seat 1 at the end face of flange of conversion sleeve 2, bolt through-hole 6 is identical with the diameter basic size of screwed hole 5 is b.
The course of work of the present utility model is:
With reference to Fig. 6, first, the aperture of the derrick leg 3 of testing as required, selects the conversion sleeve 2 in identical endoporus 7 aperture; Then, conversion sleeve 2 is loaded the derrick leg 3 of testing with needs in the sleeve joint hole 8 of ear seat 1 to be socketed; Finally, by the bolt through-hole 6 of conversion sleeve 2, set bolt is threaded with the screwed hole 5 of ear seat 1, fixing reliable.
When keeping ear seat 1 constant by changing the conversion sleeve 2 of different endoporus 7, to change the aperture of frock bearing, thus realizing the assembling of different derrick type, improve the versatility of this frock.
