Description
Technical field
The utility model relates to hydraulic blow out preventer technical field, especially side door of blowout preventer opening device.
Background technology
Preventer is an important device in oil drilling well control system, in the maintenance process of preventer, the flow process of the overwhelming majority all needs to open replacing and the maintenance that side door carries out internal part, and need the pressure bearing tens of MPa at work due to preventer, therefore between its each parts, tightness is very high and assembly is heavy, almost be combined as a whole between side door and main body, and also do not occur that at present apparatus for examination and repair that a kind of professed machine degree is higher is to realize the unlatching of side door in the maintenance process of hydraulic blow out preventer, rely on the instruments such as conventional crowbar to open side door completely with manpower, inefficiency and there is larger potential safety hazard.
Summary of the invention
The utility model is mainly difficult to the problem of opening for preventer side door in maintenance process, design side door of blowout preventer opening device, utilize the frictional force that expansion slips and bolt hole inwall produce, and piston rod to body sidewall produce to top power, can be supported between side door of blowout preventer and body, adopt remote control mode, the oil cylinder controlled by high-pressure hydraulic pump is expanded extension module, avoid the outside that is difficult to put forth effort and from bolt hole inwall insertion tool, realize being separated unlatching between side door with blowout preventer body.Its technical scheme is: cylinder body and the extension module of double acting hydraulic cylinder are fixed together, piston footstock is connected with at pistons end, with extension module, there is identical inclined plane inside slips, with its formation sliding pair, the inner hole of slips and side door to be opened, relative sliding between slips and extension module and have angular compliance, when hydraulic cylinder stretches out piston, extension module is expanded slips under the effect of opposite force.Pressure increase between the outside tooth of slips and bolt hole inwall, and then stiction increases, pass through sliding pair, hydraulic power can be delivered on side door to be opened, in addition piston footstock to blowout preventer body produce to top power, realize being separated between side door with blowout preventer body, reach the object that side door is opened.
Slips is made up of the tiles steel disc of 3 outside processing multiple tracks teeth groove.
Double acting hydraulic cylinder relies on the hydraulic power work of Remote.
After side door is fully opened, installed on the piston rod by oil cylinder clamper for disassembling, manipulation hydraulic power makes hydraulic cylinder reverse operation, piston rod reclaims, and piston footstock encounters clamper for disassembling, and extension module starts to move ahead, friction pair between slips and side door bolt hole inwall is removed, provision for disengagement.
The utility model practicality reasonable in design, greatly reduces the labour intensity of workman, decreases the risk of work, improves preventer repair quality and efficiency, ensure that oil drilling safety, is applicable to popularity and uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
1, as shown in Figure 1, side door of blowout preventer opening device, is formed primarily of double acting hydraulic cylinder 1, extension module 2, slips 3, piston footstock 4 and clamper for disassembling 5; Cylinder body and the extension module 2 of double acting hydraulic cylinder 1 are fixed together, piston footstock 4 is connected with at pistons end, with extension module 2, there is identical inclined plane inside slips 3, with its formation sliding pair, the inner hole of slips 3 and side door to be opened, relative sliding between slips 3 and extension module 2 and have angular compliance, when hydraulic cylinder stretches out piston, extension module 2 is expanded slips 3 under the effect of opposite force.
Utility model works flow process: cylinder body and the extension module 2 of double acting hydraulic cylinder 1 are fixed together, piston footstock 4 is connected with at pistons end, slips 3 is made up of the tiles steel disc of 3 outside processing multiple tracks teeth groove, has identical inclined plane, with its formation sliding pair inside slips 3 with extension module 2, double acting hydraulic cylinder 1 relies on the hydraulic power work of Remote, the inner hole of slips 3 and side door to be opened, due to can relative sliding and have angular compliance between slips 3 and extension module 2, when hydraulic cylinder stretches out piston, extension module 2 is expanded slips 3 under the effect of opposite force, pressure increase between the outside tooth of slips and bolt hole inwall, and then stiction increases, by this sliding pair, hydraulic power can be delivered on side door to be opened, in addition piston footstock to blowout preventer body produce to top power, realize being separated between side door with blowout preventer body, reach the object that side door is opened.
Embodiment 1
When side door opened by needs, piston footstock 4 one end is put into the bolt hole of blowout preventer body and side door, until slips 3 position is in the bolt hole position of side door, and give certain reverse pretightning force, remote-control hydraulic power makes double acting hydraulic cylinder 1 work under hydraulic action, extension module 2 makes on slips 3 inwall being pressed in side door bolt hole tightly, and piston footstock 4 stretches out, until be against outside blowout preventer body simultaneously.Continue to apply hydraulic power, reverse hydraulic coupling is delivered to side door by extension module 2 and slips 3, drives side door to be separated with body, until piston rod 3 stretches out completely.After side door is fully opened, this opening device need be dismantled, oil cylinder clamper for disassembling 5 is installed on the piston rod, manipulation hydraulic power makes hydraulic cylinder 1 reverse operation, piston rod reclaims, and when piston footstock 4 encounters clamper for disassembling 5, extension module 2 starts to move ahead, sliding pair between slips 3 and side door bolt hole inwall is removed, and provision for disengagement can freely be taken out.
