Description
technical field:
The utility model relates to oil field equipment and facility, is specifically related to a kind of disconnected bar oscillatory type multiple-bowl overshot.
background technology:
The salvaging construction of oil pumper superficial part rod parting, all utilize crane to complete voluntarily by production crew, particularly Sanyuan District producing well dirt card is comparatively serious, crane is put forward in process the situation that is hampered and happens occasionally, and a heavy load for crane is again limited, the disconnected bar fishing socket structure of current use is single, only have a tooth, cause fishing failure, operation team can only be reported, construction completes, and creates a large amount of job execution expenses.
utility model content:
The purpose of this utility model is the weak point existed to overcome above-mentioned prior art, and provides a kind of disconnected bar oscillatory type multiple-bowl overshot, and it is easy to use, simple to operate, be easy to large-scale promotion application.
The technical solution adopted in the utility model is: a kind of disconnected bar oscillatory type multiple-bowl overshot, comprise oscillator and connect plug, vibrating spear, vibrating spear overcoat and vibrating spear switch locking plate, be provided with vibrating spear overcoat on the right side of oscillator connection plug and be threaded connection between the two, vibrating spear jacket internal cover has vibrating spear switch main body and vibrating spear switch main body is connected plug one end connects with oscillator, vibrating spear switch main body outer cover has vibrating spear switch main body spring, the vibrating spear switch main body other end is provided with vibrating spear switch main body jump ring, vibrating spear switch main body jump ring is connected with vibrating spear switch locking plate, vibrating spear is provided with on the right side of vibrating spear switch locking plate, be provided with fishing socket connector on the right side of vibrating spear overcoat and be threaded connection between the two, secondary fishing socket is provided with on the right side of fishing socket connector, secondary fishing socket inside is provided with slips support spring, be provided with slips on the right side of slips support spring and slips to be positioned at secondary fishing socket inner, one-level fishing socket is provided with on the right side of secondary fishing socket, one-level fishing socket is identical with the internal construction of secondary fishing socket.
The beneficial effects of the utility model are: have oscillation functions, and its function is when carrying sucker rod chance card on crane, when exceeding assumed load, oscillator switch is opened automatically, vibration cylinder is clashed in vibrating spear slippage makes it produce vibration, and the impact force of generation makes polished rod Tuo Ka, and fishing is completed smoothly.A multiple-bowl overshot, makes single-stage slips become multistage slips work, increases the intensity of slips card sucker rod, and during to ensure fishing, sucker rod not slippage, decreases much unnecessary operation, make construction convenient.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
detailed description of the invention:
With reference to Fig. 1, a kind of disconnected bar oscillatory type multiple-bowl overshot, comprise oscillator and connect plug 1, vibrating spear 6, vibrating spear overcoat 7 and vibrating spear switch locking plate 5, be provided with vibrating spear overcoat 7 on the right side of oscillator connection plug 1 and be threaded connection between the two, vibrating spear overcoat 7 internal sleeve has vibrating spear switch main body 2 and vibrating spear switch main body 2 is connected plug 1 one end connects with oscillator, vibrating spear switch main body 2 outer cover has vibrating spear switch main body spring 3, vibrating spear switch main body 2 other end is provided with vibrating spear switch main body jump ring 4, vibrating spear switch main body jump ring 4 is connected with vibrating spear switch locking plate 5, vibrating spear 6 is provided with on the right side of vibrating spear switch locking plate 5, be provided with fishing socket connector 8 on the right side of vibrating spear overcoat 7 and be threaded connection between the two, secondary fishing socket 9 is provided with on the right side of fishing socket connector 8, secondary fishing socket 9 inside is provided with slips support spring 11, be provided with slips 12 on the right side of slips support spring 11 and slips 12 to be positioned at secondary fishing socket 9 inner, one-level fishing socket 10 is provided with on the right side of secondary fishing socket 9, one-level fishing socket 10 is identical with the internal construction of secondary fishing socket 9.Have oscillation functions, its function is that when carrying sucker rod chance card on crane, when exceeding assumed load, oscillator switch is opened automatically, and vibration cylinder is clashed in vibrating spear slippage makes it produce vibration, and the impact force of generation makes polished rod Tuo Ka, and fishing is completed smoothly.A multiple-bowl overshot, makes single-stage slips 12 become multistage slips 12 and works, and increases the intensity of slips 12 card sucker rod, and during to ensure fishing, sucker rod not slippage, decreases much unnecessary operation, make construction convenient.
