Abstract
The utility model discloses an injection head chain anti-shake roller device and relates to auxiliary equipment in the exploitation of oil fields. A chain anti-shake roller consists of a shaft, a left shaft sleeve, a bearing, a bearing spacer sleeve, a bearing sleeve, a right shaft sleeve, an adjusting ring, a washer and a nut, wherein one end of the shaft clamps a left large plate; the left shaft sleeve penetrates in the shaft and tightly leans on the left large plate; two bearings are embedded on the bearing sleeve with the middle being retained by the bearing spacer sleeve; the left end of the bearing is retained by the left shaft sleeve and the right end is retained by the right shaft sleeve; the right shaft sleeve contacts the adjusting ring that tightly leans against a right large plate; and the other end of the shaft causes the shaft to be firmly fixed on the right large plate through the washer and the nut. A chain expansion oil cylinder is installed at the upper part of a lower sprocket wheel and props against the lower sprocket wheel so that the chain expands tightly. The chain anti-shake roller inside the outer ring of the chain contacts the chain closely and forces the chain outwards and prevents the chain from shaking.
Description
Technical field
Injection head chain anti-shaking roller devices described in the utility model relates to a kind of auxiliary equipment of oil oilfield exploitation.
Background technology
The coild tubing unit gas collection, the liquid, electrical integrated that in the work of oil oilfield exploitation, use at present, complex structure, the automaticity height is used to transport and remove coiled tubing.During coild tubing unit work, coiled tubing twines on reel once inferiorly, stretches, and in production tube or sleeve pipe in the injection head lower going-into-well, finishes well workover and other operations.Injection head be by two synchronously can positive and negative running the fluid motor-driven chain, move up and down to drive fixture block clamping coiled tubing.Hydraulic motor is the low-speed big radial plunger piston motor, has the brake protective device.Chain and fixture block link together to adapt to the external diameter of oil pipe.Injection head removes frictional force that oil pipe produced by the briquetting pinch rollers with generation by hydraulic cylinder.The swelling oil cylinder is housed in addition is used for the swelling chain.Injection head top is equipped with the oil pipe leading truck, and its effect is that the coiled tubing that is wrapped on the reel is introduced in the injection head chain drive-belt, makes oil pipe promote oil pipe out to oil well or from oil well down smoothly.Because oil pipe is very fast in the range request speed excessively of descending oil well or oil pipe is promoted out from oil well, make that the chain shake is serious, the anti-shake of chain mainly is to make chain tightens by horizontal swelling oil cylinder and horizontal clamping cylinder acting in conjunction on the injection head of oil field use in the past, the width of injection head is increased, take very large tracts of land in working vehicle, simultaneously cost height, weight are big.At existing problem in the above-mentioned prior art, a kind of novel injection head chain anti-shaking roller devices of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel injection head chain anti-shaking roller devices of research and design, laterally swelling oil cylinder and horizontal clamping cylinder acting in conjunction made chain tightens in the past thereby solve, thereby cause the width of injection head to increase, in working vehicle, take very large tracts of land, problem such as simultaneously cost height, weight be big.Injection head chain anti-shaking roller devices described in the utility model, injection head is made up of upper sprocket wheel, oil motor, floating clamp, clamping cylinder, chain, synchromesh gear, fixture block, chain swelling oil cylinder, lower sprocket, oil pipe and big plate.In the outer shroud installed inside of chain the anti-shake roller of chain, the anti-shake roller of described chain is made up of axle, left axle sleeve, bearing, bearing spacer, bearing holder (housing, cover), right axle sleeve, adjustment ring, packing ring, nut; Axle one end blocks the big plate in left side, left axle sleeve penetrates axle near the big plate in left side, two bearings are embedded in bearing holder (housing, cover), the middle bearing spacer that leans on blocks, the left end of bearing blocks by left axle sleeve, and right-hand member blocks by right axle sleeve, right axle sleeve and adjustment loop contacts, adjust and encircle the big plate that keeps right, the other end of axle is fastened on the big plate in right side it by packing ring and nut.Described chain swelling oil cylinder is installed in the top of lower sprocket by horizontal swelling made vertical swelling into to chain originally, withstands lower sprocket, makes the chain swelling, and the anti-shake roller of chain closely contacts with chain, prevents the chain shake.Each chain of the anti-shake roller of chain described in the utility model is installed 2-3.
Injection head chain anti-shaking roller devices described in the utility model its objective is that when solving the swelling of injection head chain, actuator cylinder quantity is many, and area occupied is big on car load, problems such as cost of production height.Provide a kind of injection head chain anti-shaking unpowered roller devices.
When injection head described in the utility model is worked, upper sprocket wheel is by the oil motor driven rotary, the drive chain rotates, because chain swelling oil cylinder withstands lower sprocket downwards, thereby make the chain swelling, the anti-shake roller of chain that is installed in chain outer shroud inboard is forced chain, and chain is produced lateral force, stops the chain shake.The anti-shake roller of chain need not power, adopts the rolling friction form, reduce and chain between friction, make that fixture block clamping oil pipe steadily enters in the well on the chain.
Injection head chain anti-shaking roller devices described in the utility model, owing to adopted chain swelling oil cylinder to make vertical swelling into by original horizontal swelling to chain, be installed in the top of lower sprocket, withstand lower sprocket, make the chain swelling, the anti-shake roller of chain closely contacts with chain, prevents the measure of chain shake, not only make sprocket wheel swelling degree good, and chain installation lateral dimension is significantly reduced.
The utlity model has advantages such as novel structure, simple structure, area occupied be little, economical and practical, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
