Description

A kind of clamp device

Technical field

The utility model relates to a kind of position limiting structure, relates in particular to a kind of clamp device.

Background technology

The hydraulic pressure test machine is used to test the withstand voltage of tubing, in modern the construction use of tubing more and more widely, also more and more higher to the requirement of tubing, therefore more and more to hydraulic pressure test machine demand.Traditional hydraulic pressure test machine need be sent into tubing the test position when test tubing, then tubing is fixed, test, steel pipe can bear bigger pressure in the test process, if the device poor effect spacing to steel pipe, cause very easily that steel pipe comes off in the test process, cause the accident; And steel pipe has more specifications such as different model and different length, and stop means also needs to be suitable for the steel pipe of these different sizes.

The utility model content

The utility model provides a kind of clamp device safe and reliable, applied widely for solving the prior art problem.

The technical solution of the utility model is: a kind of clamp device, comprise mainframe, on the described mainframe clamp device is installed, be provided with cylinder in the described clamp device, the cylinder piston upper end is provided with the anchor ear assembly, and described anchor ear assembly comprises first half and latter half of, and described cylinder comprises front air cylinder and exhaust hood, described first half is arranged on the front air cylinder piston rod, described latter half of being arranged on the exhaust hood piston rod.

The action principle of clamp device is: during charging, the piston-retraction of front air cylinder, first half reduces under the effect of front air cylinder piston, the piston of exhaust hood stretches out, latter half ofly under the effect of exhaust hood piston, rise, when tubing enter latter half of after, the front air cylinder piston stretches out, with first half jack-up, first half and latter half of composition anchor ear are fixed steel pipe; During discharging, the exhaust hood piston-retraction drives latter half of decline, opens anchor ear, and steel pipe is taken out.

As preferably, described first half and the latter half of cavity that is provided with constitute complete anchor ear when described first half and latter half of amalgamation, the anchor ear chamber is arranged in the described anchor ear.The anchor ear chamber holds tested tubing just, neither can produce improper pressure and cause the tubing distortion the tubing wall, has good positioning action again, and tested tubing can be shifted under pressure.

As preferably, the xsect in described anchor ear chamber is circular, rectangle or other polygons.Other polygons are generally regular hexagon or octagon, and circle, rectangle or polygonal cavity all can play position-limiting action to steel pipe preferably.

As preferably, described first half and latter half of hinged with the piston upper end of front air cylinder and exhaust hood respectively.First half and latter half of under the driving of front air cylinder and exhaust hood in hold up with horizontal two states in switch.

As preferably, described clamp device is installed on the mainframe by tension beam, and described tension beam is fixedly installed on the mainframe, and described clamp device can move or relative fixed on tension beam.Clamp device can slide on tension beam, to adapt to different steel pipe length; Long as steel pipe, can on tension beam, increase a plurality of clamp devices, make steel pipe be fixed more firmly.

As preferably, described clamp device is installed on the slide trucks, and described slides carriage is located on the tension beam, and can move on tension beam; Described first half and latter half of all with the slide trucks upper articulation; Also be provided with lock-joint on the described slide trucks, tension beam is provided with pin-and-hole, and the central shaft of described lock-joint and pin-and-hole can insert latch when relative, and when described latch inserted pin-and-hole and lock-joint, slide trucks and tension beam interfixed.

In sum, the utlity model has following advantage:

1, simple in structure, convenient fixing;

2, spacing firm, safe and reliable;

3, can regulate spacing position simply, the steel pipe that adapts to multiple different-diameter specification is fixed;

4, can be by increasing and decreasing clamp device on tension beam to adapt to the steel pipe of multiple different length specification.
