Abstract
The utility model relates to a safety ejecter with a pressing screwed plug, which comprises an ejecter body, an operating handle, a connecting rod, a sealing device, a sleeve head, a safety pin and a nut, wherein in ejecter body, one end of a metal circular cylinder is sealed and blocked by a blind plate, and an arc-shaped beveled edge is formed at the other end of the metal circular cylinder; two opposite hangers are arranged below the arc-shaped beveled edge, and pin holes are formed on the lower end parts of the two hangers; a sealing device is arranged in the center of the blind plate on the top of the ejecter body; the connecting rod passes through the sealing device and the blind plate, the sleeve head is connected to the lower end of the connecting rod, and the other end of the connecting rod is connected with the operating handle; and the safety pin is a bolt of which one end is provided with screw threads, and after the safety pin passes through the pin holes on the lower end parts of the two hangers, the nut is screwed in. Compared with the prior art, the safety ejecter has the advantages of small volume, light weight, simple structure and wide application range, is convenient to carry and operate, and can ensure the personal safety of operators completely and reduce environmental pollution effectively.
Description
One, technical field
The utility model relates to a kind of special tool of dismantling plug, is specifically related to the stifled safe stripping attachment of a kind of band silk pressing.
Two, background technology
In the process of petroleum industry exploitation, the profit pipeline freezes stifled happening occasionally, to plant head (73mm oil pipe joint hoop) segment processing be the effective way of processing pipeline in perforate on pipeline, and, use during processing pipeline after being convenient to the tapping shutoff with the 73mm plug the unimpeded back of pipeline.Next time is during processing pipeline, needing band to press dismantles the plug of shutoff, it is very high that pipeline freezes in the oil pipe of stifled back overbottom pressure, during each the dismounting, slowly unload pine, the operation of leaning to one side with pipe wrench, when plug unloads, rice surplus plug is often ejected 10 by overbottom pressure, former oily water splash and go out to cause pollution in wide area, and also there is serious potential safety hazard in this work.The production scene presses for a kind of i.e. safety band pressure dismounting plug instrument of environmental protection again at present, avoids taking place security incident and causes environment pollution.
Three, utility model content
The purpose of this utility model is exactly the defective that exists at prior art, a kind of operator's of guaranteeing personal safety is provided, effectively reduces the stifled safe stripping attachment of band silk pressing of environment pollution.
Its technical scheme is: the utility model comprises stripping attachment body, operating grip, connecting rod, sealing device, collet head, safety pin and nut.Described stripping attachment body is the end shutoff blind plate in a metallic cylinder, and the other end is provided with the arc groove, and this arc groove has two relative hangers, and the bottom of two hangers is provided with pin-and-hole; Stripping attachment bodies top blind plate central authorities are provided with sealing device, and connecting rod passes sealing device and blind plate, and its lower end is connected with collet head, and the other end is connected with operating grip; Described safety pin is the bolt that an end has screw thread, after safety pin passes the pin-and-hole of two hangers bottoms, screws in nut.
Wherein, also be provided with the draining hole on the described collet head.Described sealing device is a packing_seal.
The utility model compared with prior art, have volume little, in light weight, be easy to carry; Simple in structure, handled easily, widely applicable; Can 100% guarantee operator's personal safety, and advantage that can effective less environment pollution.
Four, description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Five, the specific embodiment
With reference to accompanying drawing, a kind of band silk pressing blocks up safe stripping attachment, comprises stripping attachment body 1, operating grip 3, connecting rod 2, sealing device 4, collet head 5, safety pin 8 and nut 9.Stripping attachment body 1 is the end shutoff blind plate in a metallic cylinder, and the other end is provided with the arc groove, and the bottom that this arc groove has 7, two hangers 7 of two relative hangers is provided with pin-and-hole; Stripping attachment body 1 top blind plate central authorities are provided with sealing device 4, and connecting rod 2 passes sealing device 4 and blind plate, and its lower end is connected with collet head 5, and the other end is connected with operating grip 3; Safety pin 8 is the bolt that an end has screw thread, after safety pin 8 passes the pin-and-hole of two hangers 7 bottoms, screws in nut 9.Also be provided with draining hole 6 on the collet head 5.Sealing device 4 is a packing_seal.
During use, stripping attachment body 1 is across the plug top that needs dismounting, safety pin 8 is passed and fastening nut behind the pin-and-hole 9; It is descending to move down handle 3 drivening rods 2 and collet head 5, and turning handle 3 makes collet head 5 dock with plug, is rotated counterclockwise handle 3, dismantles plug.Plug can't eject in stripping attachment body 1 inside, has guaranteed operator's personal safety, because packing seal device 4 is arranged at top, former oily water flows out downwards, has effectively reduced pollution.
