Description

Petroleum pipeline box cupling based on anti-drop device

Technical field

The present invention relates to a kind of box cupling, be specifically related to the petroleum pipeline box cupling based on anti-drop device.

Background technology

Pipeline conveying is carried of crude oil a kind of means of transportation most economical, rational. Pipeline conveying crude oil, connected mode between oil pipe is typically with tubing coupling and is attached, tubing coupling has tubulose box cupling body, the two ends of box cupling body have connection female thread, when using tubing coupling connected pipes, it is screwed in tubing coupling connection female thread having externally threaded oil pipe, forms oil continuative transport pipeline with this, it is achieved the continuative transport of oil. Seal connecting between above-mentioned tubing coupling of the prior art and oil pipe to be usually and be first wound around glass fiber or the rope made of hemp at the external screw thread of oil pipe, afterwards the oil pipe being tied with glass fiber or the rope made of hemp is screwed into tubing coupling, above-mentioned seal form there is the problem that one is that oil pipe and tubing coupling are installed relatively cumbersome, need to get out glass fiber or the rope made of hemp in advance, degree of tightness or thickness that additionally the rope made of hemp or glass fiber are wound around also can affect sealing effectiveness, wayward; Two is practice have shown that to adopt the form that glass fiber or the rope made of hemp are wound around to carry out oil pipe and tubing coupling sealing, and sealing effectiveness is bad, easily occurs crude oil Seepage in use procedure.

In order to solve the problems referred to above, the patent No. is a kind of self sealss tubing coupling disclosed in the file of CN201320152391.X, there is tubulose box cupling body, the two ends of box cupling body have connection female thread, the box cupling inner body wall connected between female thread at described box cupling body two ends is compounded with rubber seal ring, when oil pipe screw in box cupling body two ends connection female thread time, oil pipe end compress described rubber seal ring and and rubber seal ring between liquid-tight envelope. Adopt the self sealss tubing coupling of said structure, owing to the box cupling inner body wall connected between female thread at described box cupling body two ends being compounded with rubber seal ring, therefore when the oil pipe using the present invention to connect oil pipeline, oil pipe docks closely with the tubing coupling of the present invention, oil pipe end compress described rubber seal ring and and rubber seal ring between liquid-tight envelope, do not have crude oil seepage.

But said structure needs the petroleum pipeline having at least one end in the petroleum pipeline that two ends connect can be freely rotatable, for two ends petroleum pipeline all can not effectively freely rotatable in the case of, then cannot realize the installation of box cupling, operation has great limitation.

Summary of the invention

The technical problem to be solved is: existing two ends connect petroleum pipeline can not effective freely rotatable time, it is impossible to realize the installation of box cupling well, cause that operation has great limitation; Purpose is in that to provide a kind of petroleum pipeline box cupling based on anti-drop device solving the problems referred to above.

The present invention is achieved through the following technical solutions:

Based on the petroleum pipeline box cupling of anti-drop device, including box cupling body, the female thread being arranged on box cupling inboard wall of tube body and matching with petroleum pipeline seam external screw thread, described box cupling body two ends are provided with clamp device;

Described clamp device includes annular fastener, the latch closure being socketed on annular fastener and threadeding with annular fastener; Said two clamp device is symmetrical arranged, and is provided with connecting rod between two latch closures; Described connecting rod one end is hinged on one of them latch closure, the other end is set to hook structure, and another latch closure is then provided with the hanging hole matched with this hook structure.

The process that implements of the present invention is:

Box cupling body is rotated on one of them petroleum pipeline, until exposing petroleum pipeline road junction, then another petroleum pipeline road junction is directed at this petroleum pipeline road junction, then this box cupling body is reversely rotated, until stopping the rotation when being respectively positioned in coupling pipe body in two petroleum pipeline road junctions, finally rotate this latch closure, make annular fastener be tightly fixed on petroleum pipeline, then the hook structure in connecting rod is articulated on hanging hole.

By above-mentioned setting, without rotating petroleum pipeline, can effectively realize threadeding of petroleum pipeline and box cupling body, the installation of box cupling can be realized afterwards well. Which makes the installation connection easier, between box cupling and petroleum pipeline of box cupling more stable. And the direction screwed due to two latch closures is relative, thereby through the setting of connecting rod, can effectively prevent loosening of latch closure, reach the effect being stably connected with better.

Further, described annular fastener is be arranged in parallel by two or more and is fixed on the anchorage bar of box cupling body end after circular array, the outer combination screw thread composition being arranged on all anchorage bars and being formed after combination; It is provided with inside described latch closure and outer combination screw thread.

In order to be able to reach the fastening effect of optimum, described anchorage bar is string configuration, and the cross section of this anchorage bar is cambered surface trapezium structure.

Preferably, described anchorage bar is provided with the pad that the direction thickness along fixing end is gradually reduced.

The present invention compared with prior art, has such advantages as and beneficial effect:

1, the present invention without rotating petroleum pipeline, can effectively realize threadeding of petroleum pipeline and box cupling body, can realize the installation of box cupling afterwards well;

2, in the present invention, the installation of box cupling connection easier, between box cupling and petroleum pipeline is more stable;

3, present configuration is simple, cost performance is high, and effect is notable, is especially suitable for popularization and application.
