Abstract

The utility model provides a novel shearing anchoring is switched device belongs to petroleum production device technical field, including rivet ware and auto -change over device, still including switching mouth, seal groove, sleeve pipe, slips, centrum and push sleeve, the rivet ware constitute by push sleeve, centrum and slips, auto -change over device sets up the one end that is equipped with the slips at the rivet ware, auto -change over device is last to be equipped with and to switch mouthful, switches to be equipped with the sleeve pipe on the extra -oral hollow shaft. The beneficial effects of the utility model are that: structurally be equipped with the oil discharge passageway, simplified the working string, reduced the ground pollution that a pump in -process crude oil, sewage caused, can the anchoring take out the oil pipe post again, prevent the tubular column wriggling, reduce stroke loss, improve the pump efficiency, extension pump inspection period.

Description

A kind of novel shearing grappling switching device
Technical field
This utility model relates to petroleum recovering device technical field, particularly relates to a kind of novel shearing grappling switching device.
Background technology
In DH measure operation and sucker rod pumping production process, owing to producing or measure tubing string is in the impact of some factors Under, inevitably face tubing string and stretch, some problems such as stress deterioration.At present, on-the-spot main by down-hole oil tube anchor Determine device to solve the problems referred to above, but the bleeder of general oil pump tubing string is opened by sucker rod, when rod parting, Will emit spray operation, the most dangerous but also pollute environment, the caber formula bleeder success rate that present each elephant uses is relatively low, therefore A kind of simple and effective device is needed to solve the problems referred to above..
Utility model content
This utility model provides a kind of novel shearing grappling switching device, is structurally provided with emptying passage, simplifies Working string, has decreased crude oil during pump, ground pollution that sewage causes, again can grappling pumping pipe string, prevent tubing string compacted Dynamic, reduce loss of plunger stroke, improve pump efficiency, extend pump detection period.
For solving above-mentioned technical problem, the embodiment of the present application provides a kind of novel shearing grappling switching device, including riveting Nail device and switching device, it is characterised in that also include switching port, seal groove, sleeve pipe, slips, vertebral body and promotion set, described riveting Nail device is by promoting set, vertebral body and slips to form, and switching device is arranged on riveter and is provided with one end of slips, and switching device is provided with Switching port, the pipe axle outside switching port is provided with sleeve pipe.
As the preferred embodiment of this programme, described switching port be respectively arranged at the two ends with two seals groove up and down.
As the preferred embodiment of this programme, described sleeve pipe can slide along the pipe axle of switching device, and pass through pin Nail is fixing.
As the preferred embodiment of this programme, described slips is arranged on the vertebral body of riveter, and outside is provided with protection set.
The one or more technical schemes provided in the embodiment of the present application, at least have the following technical effect that or advantage:
Structurally it is provided with emptying passage, simplifies working string, decrease crude oil during pump, ground that sewage causes Surface pollution, again can grappling pumping pipe string, prevent string creep, reduce loss of plunger stroke, improve pump efficiency, extend pump detection period.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only Embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the embodiment of the present application.
In Fig. 1: 1, riveter, 2, switching device, 3, switching port, 4, seal groove, 5, sleeve pipe, 6, slips, 7, vertebral body, 8, push away Dynamic set.
Detailed description of the invention
This utility model provides a kind of novel shearing grappling switching device, is structurally provided with emptying passage, simplifies Working string, has decreased crude oil during pump, ground pollution that sewage causes, again can grappling pumping pipe string, prevent tubing string compacted Dynamic, reduce loss of plunger stroke, extend pump detection period.
In order to be better understood from technique scheme, below in conjunction with Figure of description and specific embodiment to upper State technical scheme to be described in detail.
As it is shown in figure 1, a kind of novel shearing grappling switching device, including riveter 1 and switching device 2, also include switching Mouth 3, seal groove 4, sleeve pipe 5, slips 6, vertebral body 7 and promotion set 8, described riveter 1 is by promoting set 8, vertebral body 7 and slips 6 groups Becoming, switching device 2 is arranged on riveter 1 and is provided with one end of slips 6, and switching device 2 is provided with switching port 3, the pipe outside switching port 3 Axle is provided with sleeve pipe 5.
Wherein, in actual applications, described switching port 3 be respectively arranged at the two ends with two seals groove 4 up and down, it is possible to act on close Envelope cavity, good sealing effect, can effectively prevent because, in pressure process, upper and lower part liquid leaks and cannot cut off bearing pin.
Wherein, in actual applications, described sleeve pipe 5 can slide along the pipe axle of switching device 2, and solid by pin Fixed, utilize sleeve pipe 5 that switching port 2 is closed, open again when needs emptying, simplify working string, decreased pump mistake The ground pollution that journey Crude Oil, sewage cause, again can grappling pumping pipe string, prevent string creep, reduce loss of plunger stroke, improve pump Effect, extends pump detection period.
Wherein, in actual applications, described slips 6 is arranged on the vertebral body 7 of riveter 1, and outside is provided with protection set, makes Slips 6 difficult drop-off, the two-way disengagement unfreezing of upper lower cone, unfreezing is thorough, easily trips out.
The above, be only preferred embodiment of the present utility model, not this utility model is made any in form Restriction, although this utility model is disclosed above with preferred embodiment, but is not limited to this utility model, any ripe Know professional and technical personnel, in the range of without departing from technical solutions of the utility model, when in the technology of available the disclosure above Hold and make a little change or be modified to the Equivalent embodiments of equivalent variations, as long as without departing from technical solutions of the utility model Hold, any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, the most still Belong in the range of technical solutions of the utility model.
