Abstract
The utility model discloses a jigger pipe-feeding machine used in the downhole operation in petroleum industry. The jigger pipe-feeding machine works together with a jigger; during the downhole operation, the jigger pipe-feeding machine puts oil pipes on the jigger in a safe way, protects the outer threads of the oil pipes, and improves the quality of the downhole operation. The jigger pipe-feeding machine comprises a fixing mechanism and a clamping mechanism; and the fixing mechanism is provided with a slide bushing, in which the slide rod of the clamping mechanism is sleeved, so that the clamping mechanism can slide in the fixing mechanism. The slide rod of the jigger pipe-feeding machine can move in the slide bushing freely and can be pulled according to the needs; and users can draw out the slide rod working as a power arm to the maximum, thereby saving labor and controlling the operation easily. Because of easy operation method, the jigger can be used in both loading and unloading oil pipes, and the utilization of the jigger is doubled. The jigger pipe-feeding machine effectively protects the outer threads of the oil pipes and improves the quality of the downhole operation.
Description
Technical field
The utility model belongs to underground work instrument, the particularly underground work jigger upper tube device of petroleum industry, and with the supporting use of jigger, with jigger on the oil pipe roll-over protective structure, the protection oil tube external thread improves the underground work quality in underground work.
Background technology
At the oil well workover scene, removing oil pipe is daily operation, and jigger is the common tool that removes oil pipe.In removing oil pipe work, protecting oil tube external thread is material particular, also is the assurance of underground work quality.For the protection oil tube external thread, must oil pipe one end be placed on the jigger during following oil pipe, clamp the oil pipe other end with elevator then, under power drives, slowly make oil pipe upright from the oil pipe slideway, could G.I.H.In construction, the main tool of jigger is common pipe wrench on the frame oil pipe for a long time, jaw is stuck in the caliber of oil pipe, and oil pipe is dragged jigger.Because of piping tool in the special use of pipe wrench right and wrong, time-consuming, the effort of jigger on the frame oil pipe, pipe wrench itself exists also that step, fulcrum are fixing, short three defectives of the power arm of force, can cause thus: one, the step that levered up on the pipe wrench of back of oil pipe becomes the obstacle that oil pipe continues to move to jigger; Two, use pipe wrench to prize in the oil pipe process, along with the change of oil pipe displacement is a fulcrum with the jigger both sides successively, the change of fulcrum and action of inertia make oil pipe restive, easily cause oil pipe or jigger to land; Three, on the oil pipe during jigger, the oil pipe gravity arm of force is about two times of the pipe wrench power arm of force, causes operator's strength that will cost a lot of money just can lever up heavy oil pipe, and oil pipe and jigger easily land and hurt sb.'s feelings under effect of inertia, are difficult to operation.Because oil pipe does not use the violation phenomenon of jigger to happen occasionally under the above-mentioned defective, because can not effectively using, jigger cause oil tube external thread to damage, become the poorly sealed major reason of tubing string seepage and had a strong impact on operation quality.
Summary of the invention
The purpose of this utility model provides underground work jigger upper tube device, as the special tool of jigger on the frame oil pipe, protects oil tube external thread to greatest extent, effectively improves the utilization rate of jigger.
Can use the present technique solution for reaching above-mentioned purpose: underground work comprises fixed mechanism and clamping device with the jigger upper tube device, and fixed mechanism is provided with sliding sleeve, and the slide bar of clamping device is set in the sliding sleeve, makes clamping device to slide in fixed mechanism.
Compared with prior art, the utlity model has following useful effect: fixed mechanism of the present utility model is fixed on the oil pipe slideway, slide bar can move freely in sliding sleeve, can spur as required, the operator can elongate the slide bar as the power arm of force to greatest extent, makes rapid operation and is easy to control.Top bottom-disc can be in low bottom-disc the shift position, to adapt to the different azimuth that oil pipe comes well head.Claw bar is connected on the slide bar by coupling block, can grasp oil pipe and prevent that slide bar from rotating, and makes the operator easily with jigger on the tubing rack.Because easy to use, the utilization rate of jigger is used during oil pipe from operation, also uses during to time oil pipe, and utilization rate doubles.Protect the external screw thread of oil pipe effectively, improved the underground work quality.
Description of drawings
Accompanying drawing 1 is the front view of the utility model structural representation.
Accompanying drawing 2 is the left view of the utility model fixed mechanism.
The specific embodiment
Below in conjunction with embodiment the utility model is done further detailed description: referring to accompanying drawing 1, underground work comprises fixed mechanism and clamping device with the jigger upper tube device, and fixed mechanism is provided with sliding sleeve 3, and the slide bar 2 of clamping device is set in the sliding sleeve 3.Clamping device also is provided with claw bar 1, and claw bar 1 is provided with claw, and the bar handle of claw bar 1 is connected with slide bar 2 with coupling block by attachment bolt, and the other end of slide bar 2 can design handle, so that use.The spacing of two claws on the claw bar 1 conforms to the pipe aperture of clamping, and the claw that can make multiple size is to adapt to the needs of various oil pipes.Fixed mechanism also comprises lateral frame 4, perpendicular support 5, top bottom-disc 6 and low bottom-disc 8, and sliding sleeve 3 is set on the lateral frame 4, and lateral frame 4 is fixed with perpendicular support 5; The bottom of perpendicular support 5 and low bottom-disc 8 are fixing.The end of low bottom-disc 8 is provided with chute 7, and top bottom-disc 6 is by being bolted on the low bottom-disc 8, referring to Fig. 2 in the chute 7.So top bottom-disc 6 can be in the chute 7 of low bottom-disc 8 shift position, to adapt to the different azimuth that oil pipe comes well head.During concrete the use, lateral frame 4 of the present utility model is formed framework with perpendicular support 5 to be welded on the low bottom-disc 8, low bottom-disc 8 is placed on the below of oil pipe slideway, top bottom-disc 6 is placed on the top of oil pipe slideway, in chute 7, adjust the position of top bottom-disc 6, top bottom-disc 6 and low bottom-disc 8 are fixed on the oil pipe slideway with bolt.Pulling slide bar 2, in the oil pipe inner chamber that the claw insertion of claw bar 1 is to be gone into the well, pulling slide bar 2 can play the job execution of oil pipe by normal operation sequence with jigger on the tubing rack.
