Abstract

The utility model relates to a square frame chain pipeline welding clamp. The utility model is mainly composed of a clamp, a few of transverse arms and a plurality of square frame chains which are connected in series. The clamp is provided with a big top thread, a hanger rod, clamping hooks and a press beam. The square frame chains can be tightly clamped by the clamp. The clamp is mainly composed of the big top thread, a pair of clamping hooks, the press beam and some accessories. The big top thread passes through the inner thread of the hanger rod, a pair of clamping hooks is connected with the both ends of the hanger rod by a hook clamping shaft, the press beam is installed at the lower surface of the top thread, and the both ends of the press beam are provided with gaps. The main body of the transverse arm is a four-prism body, one end of the transverse arm is high, and the other end of the transverse arm is low. One high end of the transverse arm is provided with the inner threads and bolts, and the both sides of the transverse arm are respectively provided with a left ear chain and a right ear chain of the transverse arm. When the utility model is used, the welded concentricity of the pipeline of the large diameter can be guaranteed, and the work efficiency can be raised.

Description

A kind of square frame chain pipe weld jig

The utility model relates to a kind of pipeline welding anchor clamps, especially a kind of square frame chain pipe weld jig.

At present, when pipeline welding, the method that the general bigger normal employing chain block of diameter adds tripod is adjusted the position of two pipelines, welding again after adjusting.This method exists that the welding error is big, concentricity is difficult to accurate control, adjusts the effort of taking a lot of work, shortcoming that work efficiency is lower.

The purpose of this utility model is that a kind of pipeline welding anchor clamps will be provided, and it can overcome above-mentioned shortcoming effectively, reduces to weld error and improves welding efficiency.

The purpose of this utility model is achieved in that it briefly is the screw thread jackscrew clip that the folder hook is arranged with, the square frame chain string that has transverse arm earlier with tensioning ring around a pipe end, and then the bolt on the adjusting transverse arm, the end of another root pipeline is welded with the method for last aligned position.The structure of clip is such: its upper end of big jackscrew of passing suspension rod middle part jackscrew internal thread is equipped with handle, and is after the lower end is passed and pressed the beam middle part, spacing fixing below pressing beam with ring washer.The two ends of suspension rod all have presses the beam gap, is equipped with nip drum axle and nip drum therein, and nip drum is positioned at the outside of two folder hooks, and the end of folder hook is the bill of inside lateral bending, and two bills can hook the two ends of the square frame chain string that has transverse arm.When screwing jackscrew, two folder hooks are drawn close mutually and are tightened up, and strain whole square frame chain string, at this moment regulate the bolt on the transverse arm again, and the end position of adjusting another root pipeline of wanting welded together gets final product.

Owing to adopt such scheme, it can effectively reduce the error of pipeline counterpart welding, improves welding quality, and, flexible operation simple in structure because of it can improve the welding work efficiency, especially larger-diameter pipeline greatly simultaneously.

Below in conjunction with accompanying drawing the utility model is described in detail.Fig. 1 is the schematic diagram that the utility model is clamped the bigger pipeline of diameter, and Fig. 2 is the left view of Fig. 1, and Fig. 3 is the front view of transverse arm, Fig. 4 is the vertical view of transverse arm, Fig. 5 is the front view of suspension rod, and Fig. 6 is the vertical view of suspension rod, and Fig. 7, Fig. 8 are respectively that the master who presses beam looks, vertical view.

In the drawings: 1, handle, 2, jackscrew, 3, suspension rod, 4, folder hook, 5, press beam, 6, the folder bill, 7, transverse arm, 8, bolt, 9, the square frame chain, 10, pipeline, 11, internal thread, 12, transverse arm left side ear chain, 13, transverse arm auris dextra chain, 14, chain hook, 15, the nip drum axis hole, 16, press the beam gap, 17, folder hook axis hole, 18, the jackscrew internal thread.

In Fig. 1, the middle part of suspension rod (3) is with externally threaded jackscrew (2) to pass, jackscrew (2) upper end is equipped with one handle (1), jackscrew (2) lower end is passed and is pressed beam (5) back to fix with ring washer, press the two ends of beam (5) to leave pressure beam gap (16), make and press the two ends of beam (5) to be fork configuration, as shown in Figure 6, in pressing beam gap (16), there is folder hook (4) to pass respectively, folder hook (4) is all at the nip drum axle inner underside of pressing beam (5) two ends, all there is bill (6) folder hook (4) lower end, and bill (6) can hook the two ends of the square frame chain string that has transverse arm (7).

In Fig. 1, Fig. 2, Fig. 3, Fig. 4, can see that square frame chain string has transverse arm (7) and a plurality of square frame chain (9) that bolt (8), both sides have transverse arm left side ear chain (12), transverse arm auris dextra chain (13) by several ends and is connected in series one by one mutually.Transverse arm (7) is as shown in Figure 3, Figure 4: at a slightly high end internal thread (11) is arranged, it can cooperate with bolt (8), transverse arm left side ear chain (12) is the part that square frame chain (9) is provided with chain hook (14), transverse arm auris dextra chain (13) is the part that square frame chain (9) does not have chain hook (14), like this, transverse arm (7) could get up with square frame chain catena.

During use, elder generation is according to the thickness of caliber, select the number of transverse arm (7), how big caliber is can be with several, and little caliber is then used several less, contacting the back around tube end as shown in Figure 1 and Figure 2: leaves suitable distance, so that can allow some leeway for folder hook (4) tension, transverse arm (7) has an end of bolt (8) to place another pipe end that will weld, behind the tension chain string, adjust bolt (8) more one by one, two pipeline locations are aligned.

Claims
