Description
Technical field
The utility model relates to a kind of bolt dismantling devices, more particularly to the bolt tension of a kind of Quick fastening and disassembly
Device
Device.
Background technique
When oil and gas pipeline leak source is repaired or discards transformation, most of a variety of plugging devices are bolted.
Such as connection, threeway and connection of sandwich valve of aperture header and sandwich valve etc..Therefore bolt fastening and disassembly be must not
The process that can lack.Such as: Φ 610 blocks totally 24 bolts hole on header connecting flange, due to the limited separation between two bolts,
It is when fastening and inconvenient.
There are two ways to current common fastening bolt: one is by covered on traditional wrench extension bar manpower compared with
Tightly, this method keeps operator very arduous, it is often necessary to four or five people operations simultaneously, time-consuming and laborious and each bolt by
Power is uneven.Another method is using hydraulic spanner, this equipment is relatively large, and the bolt that works in fastening bolt will receive torsion
Shearing and lateral force, work nut big to bolt damage and the contact surface for blocking header have frictionally damage, although work nut side
Just it replaces, but the damage for blocking header is not easy to repair.
Summary of the invention
The purpose of this utility model is to provide the bolt tensioning jack of a kind of Quick fastening and disassembly, bolt tensioning jack by
The hydraulic power supply that hydraulic pump provides, directly lifts bolt, no torsional shear and lateral force using axial tension, the contact to connection
Face protects main equipment without frictionally damage.Alleviate the operation intensity of worker.
The purpose of this utility model is achieved through the following technical solutions:
A kind of bolt tensioning jack of Quick fastening and disassembly, the bolt tensioning jack include ring nut, cylinder body, piston,
Attaching nut, support bridge, ring, driving lever；Attaching nut is set with piston, and the outer diameter of piston is set with cylinder body, ring nut
The top of attaching nut is tightened on through screw socket, the lower part of attaching nut is connected with support bridge, and the upper end of support bridge connects cylinder body,
Lower end is connected with ring, and support bridge is linked on ring, and the radial level of ring is connected with driving lever；High-pressure hose connection is hydraulic
Pump and stretching cylinder body.
The bolt tensioning jack of a kind of Quick fastening and disassembly, the cylinder body that stretches is the execution for realizing bolt tension
Element；Stretch nut attaching nut hydraulic cylinder, piston and ring.
The bolt tensioning jack of a kind of Quick fastening and disassembly, the driving lever are inserted in ring or attaching nut's fabrication hole
In.
The bolt tensioning jack of a kind of Quick fastening and disassembly, the cylinder body is in support bridge, ring nut and company
Connected nut is connected through a screw thread.
The advantages of the utility model, is with effect:
The hydraulic power supply that bolt tensioning jack is provided by hydraulic pump mitigates the operation intensity of worker.
1. the utility model bolt tensioning jack directly lifts bolt, no torsional shear and lateral force, distich using axial tension
The contact surface connect protects main equipment without frictionally damage.
2. the utility model mechanical structure is using the cramped construction of multistage assembling, easy for installation, quick.
3. the pretightning force that the utility model can accurately control bolt by prexxure of the hydraulic pump table.With guarantee multiple bolts by
The uniformity of power.
4. the utility model bolt tensioning jack can also can be used in groups with used aloned.Multiple stretchers are used in parallel,
It can not only improve efficiency.
Detailed description of the invention
Fig. 1 is the utility model main view；
Fig. 2 is the utility model section view.
Specific embodiment
The utility model is described in detail in illustrated embodiment with reference to the accompanying drawing.
The utility model designs a compact bolt tensioning jack for pipe plugging equipment, and bolt tensioning jack is by hydraulic
The hydraulic power provided is pumped, hydraulic oil, which is injected into the hydraulic cylinder of bolt tensioning jack, rises liquid piston driving attaching nut
To which elevator bolt makes the nut to be pre-tightened have enough spaces to be easy to loosen and fasten, in order to solve torsional shear and lateral force
Interference and the operation intensity for mitigating worker, are conveniently installed.
The structure of bolt tensioning jack
Bolt tensioning jack is mainly made of hydraulic pump, high-pressure hose, pressure gauge and stretching cylinder body.Bolt tensioning jack includes dialling
Ring nut 1, cylinder body 2, piston 3, attaching nut 4, support bridge 5, ring 6, driving lever 7.
Attaching nut 4 is set with piston 3, and the outer diameter of piston 3 is set with cylinder body 2, and ring nut 1 is tightened on company through screw socket
The top of connected nut 4, the lower part of attaching nut 4 are connected with support bridge 5, and the upper end of support bridge 5 connects cylinder body 2, and lower end is connected with
Ring 6, the radial level of ring 6 are connected with driving lever 7；
Wherein hydraulic pump is power source, the output pressure of pressure gauge reflected pump, high-pressure hose connection hydraulic pump and stretching cylinder
Body.Stretching cylinder body is the executive component for realizing bolt tension.Mainly by stretching nut attaching nut hydraulic cylinder, piston and ring group
At.Structure is as shown in the figure.Two need bolted equipment to be connected with, and install nut, artificial to greatest extent as far as possible
It pre-tightens.The nut to be pre-tightened is connect with ring 6, and support bridge 5 is linked on ring 6, and the bolt to be pre-tightened passes through with attaching nut 4
It is threadedly coupled, driving lever 7 is inserted in 4 fabrication hole of ring 6 or attaching nut, and for cylinder body 2 in support bridge 5, piston 3 is linked in connection spiral shell
On mother 4, ring nut 1 is connected through a screw thread with attaching nut 4.
The working principle and use of bolt tensioning jack.
Nut is screwed in above bolt top nut first and exposes about 30mm bolt, with the next installation bolt tension of spanner band
Device.Ring and support bridge are fallen in screw on attaching nut on tight nut, then covers and exposes screw thread at the top of hydraulic cylinder, with stretching
Nut is tightened, and bolt tensioning jack installation terminates.When connecting hydraulic pump, when pump increases pull-up spiral shell to hydraulic cylinder when oiling in hydraulic cylinder
Bolt makes nut and bottom off-seam, fluctuates ring at this time nut band is tight.Hydraulic pump one can drag four connections, need to install quick one
Four jointings are dragged, then hydraulic hand-pump, quick coupling need to be dismounted after pressure release.
