Abstract

The utility model relates to a hydraulic press taking-out device, which comprises a first clamp, a second clamp, a saddle, a clamping cylinder and a connecting rod, wherein the saddle is arranged between the first clamp and the second clamp, and the connecting rod is connected onto the first clamp and the second clamp. The device is characterized in that an elastic pressure block is connected to the inner lateral side of each of the first clamp and the second clamp, or a groove is arranged on the inner lateral side of each of the first clamp and the second clamp, and a convex elastic pressure block fitting the grooves is connected onto each groove. The hydraulic press taking-out device has the advantages that the area of contact of each clamp with a steel pipe is increased, each clamp is in tight contact with the steel pipe which is stressed uniformly, the surface of the steel pipe cannot be scratched, pipe sending is high in stability and accurate in positioning, and labors for polishing and the like due to scratching of the steel pipe are not needed, so that disputes caused by extra labors can be reduced.

Description

The water pressure engine that can anti-crush steel pipe clamps picks out device

Technical field

The utility model relates to the conveyer of object, specifically belongs to water pressure engine and picks out device.

Background technology

Clamping is picked out device and belonged to one of vitals of water pressure engine, and its effect is: six groups of metal clamps are fixed the steel pipe of different size through clamping cylinder, and move to the standard testing position through lift cylinder.In the use; The clamping of normal discovery water pressure engine is picked out the clamp arm and the steel pipe of device and is fitted not tight; Make and send pipe the time to make to close suffered clamping force inhomogeneous, promptly produce sliding phenomenon, again tube wall is produced impression at too tight stressed place in joint place not; Influence the presentation quality of pipeline, and can influence the accuracy of the position of transporting steel pipe.For satisfying customer requirements, need carry out follow-up polishing work to the scuffing that the steel pipe outward appearance is produced, it has increased workload and labour intensity, also causes incuring loss through delay the duration, can produce user's objection thus.

Steel tube surface scratches the main cause that is produced:

One, the clamping force of clamp is bigger, and the area that contacts with steel pipe is little, in whole moving process, because the moment of steel pipe rotates, causes pipe face circumferencial direction to scratch;

Two, after steel pipe was put in place by the integral body lifting, the pressure text head at two ends can firmly clamp steel pipe and reach airtight, thereby the variation of the radial force that it produced causes the pipe face diameter to being scratched.

The utility model content

The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of and transports at steel pipe that the surface is not scratched in the process, transport safety and stability, and device is picked out in the water pressure engine clamping that crushes steel pipe of prevent that is prone to implement.

Realize the technical measures of above-mentioned purpose:

The water pressure engine that can anti-crush steel pipe clamps picks out device; By clamp one, clamp two, be located at saddle, the clamping cylinder between clamp one and the clamp two, the connecting rod that is connected on clamp one and the clamp two is formed, it is: on the medial surface of clamp one and clamp two, be connected with elastic press respectively.

The water pressure engine that can anti-crush steel pipe clamps picks out device; By clamp one, clamp two, be located at saddle, the clamping cylinder between clamp one and the clamp two, the connecting rod that is connected on clamp one and the clamp two is formed; It is: on the medial surface of clamp one and clamp two, be processed with groove respectively, on groove, connect the convex elastic press that has with groove fit.

The characteristics of the utility model are: clamp and steel pipe not only contact area increase; And it is tight, stressed even; Can't produce steel tube surface and scratch phenomenon, and send the pipe action stability good, put in place accurately; And need not to have reduced the dispute that therefore causes owing to steel pipe is scratched labour payment such as polish.

Embodiment

Do below in conjunction with accompanying drawing and to further describe:

Embodiment 1

Describe in conjunction with accompanying drawing 1:

The water pressure engine that can anti-crush steel pipe clamps picks out device, by clamp 1, clamp 22, be located at saddle 3, the clamping cylinder 4 between clamp 1 and the clamp 22, the connecting rod 5 that is connected on clamp 1 and the clamp 22 is formed.It connects the elastic press 6 by flexible plastic material through screw or bonding agent respectively on the medial surface of clamp 1 and clamp 22, preferably adopt elastic press 6 that the inboard of clamp 1 and clamp 22 is clipped in mode wherein, uses bolt then.

Embodiment 2

Describe in conjunction with accompanying drawing 1 and accompanying drawing 2, accompanying drawing 3:

The water pressure engine that can anti-crush steel pipe clamps picks out device, by clamp 1, clamp 22, be located at saddle 3, the clamping cylinder 4 between clamp 1 and the clamp 22, the connecting rod 5 that is connected on clamp 1 and the clamp 22 is formed.It is processed with groove 7 respectively on the medial surface of clamp 1 and clamp 22, on groove 7, adopt embedded mode and add the bonding agent connection to have the convex elastic press 8 that cooperates with groove 7.

The operating principle of the utility model does not become.
