Abstract
The utility model relates to the field of petroleum drilling machine derrick auxiliary devices, and particularly relates to a support device used for a petroleum drilling machine derrick and a base seat lifting hydraulic cylinder. The support device comprises an adjusting hydraulic cylinder and a supporting plate hinged on the adjusting hydraulic cylinder, and the supporting plate is capable of being in supporting fit with an outer sleeve of the lifting hydraulic cylinder. When the support device is used, the lower end of the adjusting hydraulic cylinder is enabled to be fixedly connected with and perpendicular to a base seat, and is in supporting fit with the middle portion of the lifting hydraulic cylinder through the supporting plate arranged at the other end of the adjusting hydraulic cylinder, the circling of the lifting hydraulic cylinder and the change of an angle between the lifting hydraulic cylinder and a horizontal plane are achieved through displacement changes of a supporting piston rod of the adjusting hydraulic cylinder, accurate adjustment enables the single earboard hole and double earboard holes to be coaxial and therefore a connecting pin is enabled to penetrate through the holes smoothly. The petroleum drilling machine lifting hydraulic cylinder support device has the advantages that the extension and retraction of the hydraulic control adjusting hydraulic cylinder is both accurate and safe, the defects of hard lifting caused by coverings located on the top portion of the lifting hydraulic cylinder are overcome, and the lifting hydraulic cylinder is enabled to be smooth to install or detach.
Description
Technical field
The utility model relates to oil-well rig boring tower auxiliary equipment field, is specifically related to a kind of oil-well rig boring tower and base raising cylinder bracing or strutting arrangement.
Background technology
Existing derrick and base must be installed before the raising cylinder work when mounted generally by means of raising cylinder, and the fluid cylinder lower end is installed on the fixing pedestal, and tailpiece of the piston rod is connected with the parts that position quilt up hoists.After the lower end was lifted into the position and squeezes into pin, the connection of upper piston rod end was often owing to there being veil, and crane can not hang the installation site with fluid cylinder, gave the pin strip of piercing one's ears is installed comes very large difficulty, had affected the efficient of derrick and floor installation.
The utility model content
The purpose of this utility model is exactly the defective that exists for prior art, a kind of flexible operation is provided, regulates accurately oil-well rig raising cylinder bracing or strutting arrangement, solves oil-well rig boring tower and base hydraulic cylinder and meets veil installing/dismounting technical barrier.
The concrete technical scheme of the utility model is: comprise and regulate fluid cylinder and upper hinged supporting plate thereof, and described supporting plate can cooperate with the overcoat support of raising cylinder.During use, to regulate fluid cylinder lower end and pedestal in vertical state affixed, and cooperate by the support of other end mounting plate and lifting hydraulic cylinder middle part, the angle of socializing with horizontal plane that realizes raising cylinder by the change in displacement of regulating fluid cylinder support piston bar changes, the accurate adjusting makes single ears plate hole coaxial, penetrates smoothly the connection pin.
Because the overcoat of most raising cylinders is cylindric, therefore the Cross section Design of described supporting plate is arc, is convenient to the stable support of the two, and the supporting plate inner surface is provided with rubber pad, plays the damping depressurization, avoids it to be subject to impact, heel and toe wear.
The hinged place of described adjusting fluid cylinder and supporting plate is provided with spacing locating piece, is used for the angle of the inclination of restriction supporting plate.
The utlity model has following advantage: the again safety of stretching accurately of fluid cylinder is regulated in hydraulic control, arc can cause that along with the variation of bracing or strutting arrangement height the angle of inclination changes, drive the variation of lift oil tank position, thereby overcome because the lift oil tank top has overcover to cause the defective of lifting difficulty, make smoothly installation or removal of oil cylinder.

Wherein: A, derrick main body, B, pedestal, C, raising cylinder, 1, arc, 2, rubber pad, 3, bearing pin, 4, regulate fluid cylinder, 5, bolt, 6, nut, 7, packing ring, 8, spacing locating piece.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1, a kind of oil-well rig raising cylinder bracing or strutting arrangement is comprised of arc 1, rubber pad 2, bearing pin 3, adjusting fluid cylinder 4, bolt 5, nut 6, packing ring 7 etc.Regulate fluid cylinder 4 one ends affixed by bolt 5, nut 6, packing ring 7 and pedestal B, and make adjusting fluid cylinder 4 keep plumbness, the other end and arc 1 are hinged, and the rubber pad 2 that arc 1 inner surface is provided with plays the damping depressurization, avoid it to be subject to impact, heel and toe wear.
This principle of device is: arc 1 bottom has otic placode to be connected with adjusting fluid cylinder 4, and under the restriction of spacing locating piece 8, be in heeling condition, regulate fluid cylinder 4 height change, tilt to cause and the variation of arc 1 with the raising cylinder C position that is integrated thereby drive arc 1 thereupon.Namely regulate fluid cylinder 4 piston rod strokes by adjusting, and then the angle of inclination of the fluid cylinder C that adjusts hoisting.
Before derrick or base hoist, raising cylinder C is placed on the arc 1, at this moment, raising cylinder C and arc 1 become one.Regulate the collapsing length of fluid cylinder 4 and raising cylinder C by hydraulic control, the piston rod head otic placode that makes raising cylinder C and derrick or the base lug plate holes that hoists is coaxial, penetrates smoothly pin realization derrick or base and hoists.
After derrick or base hoist and finish, get top pin raising cylinder C piston rod retraction, regulate fluid cylinder 4 and regain, the supporting arrangement height descends, and last raising cylinder C and this device namely are in the state of sealing up for safekeeping.
Claims (3)
1. an oil-well rig raising cylinder bracing or strutting arrangement is characterized in that: comprise and regulate fluid cylinder and upper hinged supporting plate thereof, and described supporting plate can cooperate with the overcoat support of raising cylinder.
2. according to oil-well rig raising cylinder bracing or strutting arrangement claimed in claim 1, it is characterized in that: the cross section of described supporting plate is arc, and its inner surface is provided with rubber pad.
3. according to claim 1 or 2 described oil-well rig raising cylinder bracing or strutting arrangements, it is characterized in that: the hinged place of described adjusting fluid cylinder and supporting plate is provided with spacing locating piece.
