Abstract
The utility model relates to a double-clamp oil pumping rod reverse fastener, belonging to the improvement of a construction tool in oil development engineering. Mainly, the double-clamp oil pumping rod reverse fastener is clamped in a hydraulic pipe clamp clip through clamping and relieve devices arranged on two ends of a force bearing cylinder, and thereby, a series of problems which are generated when an oil pumping rod bears force and is reversely fastened are solved. The double-clamp oil pumping rod reverse fastener is mainly composed of the force bearing cylinder, anti-jumping plate, a clamping tile seat, a clamping tile, etc.
Description
The utility model designs a kind of novel two card sucker rod reverse buckling equipments, it is the improvement that belongs to construction tool in the petroleum development engineering, mainly be by two ends card to be set to separate device at loaded cylinder, and it is stuck in the hydraulic pipe wrench card, thereby sucker rod a series of problems stressed and that when back-off, taken place have been solved.It mainly is to be formed by combining by loaded cylinder, anti-springboard, bowl and slips.
In the construction of petroleum development engineering, especially when the sucker rod back-off of workover treatment, with manpower swivelling pipe pincers, realize purpose often with the sucker rod back-off.But it is often very big because of the distortion elastic force of sucker rod, the necessary close fit of shaft mouth operation personnel, carelessness is arranged slightly or operate bad, pipe wrench is slipped out of the hand, this moment, the pipe wrench of rotation then can wound the operating personnel, and also very difficult with the pipe wrench back-off because the distortion elastic force of sucker rod can drive oppositely rapidly rotation of pipe wrench, sometimes even can not back-off, propose unfreezing on often needing energetically this moment.The drawback of putting forward releasing method on using energetically is: often easily sucker rod is pulled off or pull-off, and sucker rod can scrap because of bearing above the pulling force of yield limit, and the sucker rod of a bite oil well is generally all more than 1000 meters, in case scrap then waste surprising.So how to address the above problem is that the engineering staff of job site and scientific research personnel are exploring and yearning for always.
A kind of novel two card sucker rod reverse buckling equipments that the purpose of this utility model provides with regard to being to avoid the deficiencies in the prior art part, it mainly is force way and a fastening means of improving sucker rod, thereby has solved a difficult problem in the prior art effectively.This pair card sucker rod reverse buckling equipment mainly is to be formed by combining by loaded cylinder, anti-springboard, bowl and slips, its major technology characteristics are to be provided with anti-springboard at the two ends of loaded cylinder, the slip spider that slides for slips is set in the upper end of anti-springboard again, slip spider top then is provided with one group of slips, this group slips is undertaken fastening by bolt, the inwall of slips then is provided with the slips core.
Accompanying drawing 1 is top structure schematic diagram of the present utility model.
Accompanying drawing 2 is side structure schematic diagram of the present utility model.
The drawing of accompanying drawing is described as follows:
1----bolt 2----slips 3----prevents springboard 4----loaded cylinder
5----slip spider 6----cottor pin 7----slips core
In order to realize better above-mentioned purpose of the present utility model, designer of the present utility model also will The slips group is designed to be can be along the slips of slip spider slip by two; The inwall of this slips is set The slips core be removable, and fixed by split pin; The length of loaded cylinder is then established as required Fixed, generally about 0.6～1.0 meter; The fastener of slips group then be designed to be by Two bolts that are arranged on the slips two ends consist of.
Come enumeration design feature of the present utility model below in conjunction with drawings and Examples:
In actual design with in making, designer of the present utility model gets a joint steel pipe as loaded cylinder of the present utility model, and anti-springboard is set at the loaded cylinder two ends, and on anti-springboard, the slip spider that slides for the slips group is set, then being provided with on the slip spider can be along one group of (two) slips of slip spider slip, be inlaid with the slips core that can change flexibly on the inwall of this slips, this slips core can be fixed it by cottor pin.Like this, in practice of construction, on-the-spot operating personnel with sucker rod pass loaded cylinder two ends and with slips with sucker rod fastening it, be stuck on the outer wall of loaded cylinder of the present utility model with hydraulic tubing tong again, can leave the scene of well head, and realize purpose with the sucker rod back-off by hydraulic tubing tong, even the sucker rod bounce-back can not hurted sb.'s feelings yet.Reversing torque of the present utility model is big, and success rate improves greatly, uses the utility model to propose unfreezing on also having avoided energetically simultaneously and surpasses yield limit and wasting phenomenon that sucker rod is scrapped by its sucker rod pulling force that causes.
The utility model is simple in structure, and is reasonable in design, and cost of production is lower, and solved bothersome sucker rod back-off problem in the petroleum works, has popularizing application prospect widely.
