Abstract

The utility model relates to a quick alignment clamp for pipeline welding, which is mainly composed of a big top thread passing through an inner screw of a hanger rod, a pair of clamping hooks connected to both ends of the hanger rod by a hook clamping shaft, a press beam arranged below the top thread and a plurality of accessories. The big top thread is screwed in to push the press beam forward, and simultaneously a boom drives the clamping hook to be pulled backward, which causes the clamping hook to be furled to clamp one end of a pipeline, and then, three small top threads on the cross arms of the two clamping hooks and a cross arm of the press beam are regulated to make the three small top threads clamp one end of another pipeline and align to the first pipeline to facilitate the welding operation. The use of the quick alignment clamp for pipeline welding can sufficiently ensure the concentricity of the two welded pipelines to enhance the welding quality.

Description

The quick counterpart anchor clamps of pipeline welding

The utility model relates to the quick counterpart anchor clamps of a kind of pipeline welding.

At present, when the pipeline counterpart is welded, the effective artificial hand-held butt welding that general diameter is less, the method that the chain block commonly used that diameter is bigger adds tripod is adjusted the position of two pipelines and is welded.More than two kinds of methods all have a common shortcoming, that is exactly that the error of welding is bigger, concentricity is difficult to accurate control, and the second method effort of especially taking a lot of work, work efficiency is lower.

The purpose of this utility model will provide a kind of pipeline welding quick counterpart anchor clamps exactly, and the error when it not only can reduce the welding of pipeline counterpart also can be increased work efficiency simultaneously.

The purpose of this utility model is to realize like this; There is big jackscrew to pass at the middle part of suspension rod, big jackscrew upper end is equipped with handle, big lower end of top thread withstands in the top wire hole of pressing the beam middle part, the two ends of suspension rod are connected with a pair of folder hook by folder hook axle, one section of the folder hook is straight section, and the end of straight section is connected with suspension rod by folder hook axle, the terminal inwardly lateral bending of each folder hook, end respectively has a quadrangular clevis hook transverse arm, and an end of folder hook transverse arm is equipped with little jackscrew.Press two ends, the beam left and right sides all to have and press the beam gap, in them, all be equipped with nip drum axle and nip drum thereof, two folder hooks pass the pressure beam gap below nip drum respectively, nip drum is positioned at the outside of folder hook, pressing the beam middle part to be provided with top wire hole can cooperate with big jackscrew front end, presses the beam middle part to form to the both sides horizontal expansion respectively and presses the beam transverse arm, presses an end of beam transverse arm to be provided with internal thread, and can cooperate with little jackscrew, its shape function is with folder hook transverse arm.Their effect all is that the end of a pipeline can be clamped by elder generation of transverse arm, and has the transverse arm of three little jackscrews to rely on three little jackscrew roll adjustments, the end of withstanding another root pipeline, and with last align so that two pipelines are aligned welding.

Owing to adopted such scheme, the error when it can reduce the welding of pipeline counterpart improves welding quality, and it also has the characteristics of processing ease simple in structure simultaneously.

Below in conjunction with drawings and Examples the utility model is described in detail: Fig. 1 is a front view of the present utility model, Fig. 2 is the right view of Fig. 1, Fig. 3 is the schematic diagram of the utility model when clamping the lower diameter tube road, and Fig. 4, Fig. 5 are respectively that the master who presses beam looks, vertical view.

In the drawings: 1, big jackscrew handle, 2, big jackscrew, 3, suspension rod, 4, press beam, 5, the nip drum shaft retaining ring, 6, the folder hook, 7, little jackscrew handle, 8, little jackscrew, 9, folder hook axle, 10, nip drum, 11, the nip drum axle, 12, folder hook transverse arm, 13, folder hook shaft retaining ring, 14, press the beam transverse arm, 15, top wire hole, 16, press the beam gap, 17, internal thread.

In Fig. 1, the middle part of suspension rod (3) is with externally threaded big jackscrew (2) to pass, big jackscrew (2) upper end is equipped with one handle (1), big jackscrew (2) lower end withstands in the top wire hole (15) of pressing beam (4) middle part, press the two ends of beam (4) to leave pressure beam gap (16), make and press the two ends of beam (4) to be fork configuration, as shown in Figure 5, in pressing beam gap (16), be equipped with nip drum axle (11) and nip drum (10), the thin end of nip drum axle (11) is equipped with ring washer (13), have a transverse arm both to press beam transverse arm (14) at the middle part of pressing beam (4), its structure and function are with following described folder hook transverse arm (12), and it also is to be integrative-structure with pressing beam (4).After two folder hooks (6) pass the pressure beam gap (16) of pressing beam (4), be positioned on the two ends of suspension rod (3) by folder hook axle (9), nip drum (10) is in the outside of folder hook (6), the end of folder hook (6) has a folder hook transverse arm (12) of one with it, and folder hook transverse arm (12) is that one one end can be pushed down the four prisms cylinder that pipeline, the other end have little jackscrew (8).

Elder generation's big jackscrew of spin-up (2) loosens folder hook (6) during use, make the spacing of two folder hooks (6) become big so that these anchor clamps can be enclosed within the pipe end that will weld, and then oppositely screw big jackscrew (2), suspension rod (3) is pulled upwardly together with folder hook (6), press beam (4) to be pushed downwards, suspension rod (3) becomes big with pressing beam (4) distance, nip drum (10) is pressing clip hook (6) simultaneously, folder hook (6) is put together to be tightened up, make at last and press beam transverse arm (14), two folder hook transverse arms (12) are clamped the end of pipeline together, at this moment the end of putting into another root desire pipeline welded together is between three little jackscrews (8), tighten three little jackscrews (8) then one by one, up to the position of this root pipeline is mixed up fixing just can weld job, its work schematic diagram is as shown in Figure 2.
