Abstract

The utility model discloses a hinged type pipe to pipe external joining means, which comprises an inverted V-shaped support frame, a three-way shaft capable of rotating correspondingly, a connection handle, a reversible shaft sleeve, a chain connected with the handle, a chain locking slot, a position limiting hook, etc. The utility model utilizes the corresponding rotary structure among the support frame, the three-way shaft and the shaft sleeve to realize the up and down rotation and the left and right rotation on the handle, and simultaneously the chain drives the other pipeline to realize the joining of the vertical direction and the horizontal direction. The utility model has simple structure and only needs one-man operation; through experiment, the labor and the time can be saved by 4-6 times, the quality of the butt-joint processing is enhanced by 20%-30%, and the range of application is big. The utility model can be used for joining the pipeline with various standards and dimensions.

Description

Hinge type pipeline external clamp

The utility model relate to pipeline counterpart welding to mouthpart.

In petrochemical industry, hot-water heating industry, building or the like industry; run into the butt joint operation of petrochemical pipe, hot-water heating pipeline, steel building or the like through regular meeting; because pipeline is not only thick but also long; counterpart is very difficult during welding; need to lift tripod, a people by jack by two people; not only tiring but also time-consuming, and be difficult to guarantee the counterpart quality." the portable pipeline outer shaping to mouthpart " of the patent No. 87209238 utilize two semicircular to the mouthpart clamping plate, three dunnages on it are connected, establish a shaping pawl and a counterpart positioning pawl on the dunnage, two pawls are cooperated along mouthpart is stretched in radially by drive bolt and nut, and being provided with ball not damage the coating of welded tube mouth, this also must load and unload bolt and nut to the mouthpart complex structure during counterpart, use trouble, and can only be applicable to a kind of pipeline counterpart of specification.

The purpose of this utility model is to overcome the defective of prior art and a kind of hinge type pipeline external clamp that saves time, guarantees the counterpart quality simple in structure, laborsaving is provided.

The technological scheme that realizes above-mentioned purpose is such: comprise support and chain, described support is down " V " font, is supporting relatively turnable three-way axis in the support, and being set with on the axle also can rotating axle sleeve with the handle one, and nut is fixed on the three-way axis top; Described chain is fixed on and the first side of the handle of handle one, and opposite side is provided with the stop hook on chain locking slot and locking slot both sides.

The utility model is to fall the support of " V " font structure as the benchmark piece of a pipeline, utilize the structure that relatively rotates between support, three-way axis, the axle sleeve to realize rotating up and down and turning left and right of handle, and simultaneously drive another pipeline and be stuck and counterpart with chain, thereby realize counterpart welding purpose, it is simple in structure, only needs the one man operation, laborsavingly save time 4-6 doubly, the butt joint processing quality improves 20%-30%, and Applicable scope is big, can be used for the pipeline counterpart of plurality of specifications size.

Embodiment to the utility model is described in detail again below in conjunction with above-mentioned accompanying drawing.

Hinge type pipeline external clamp (referring to Fig. 1-8) has a support (7) that is down " V " font, is welded by steel plate, and it is the benchmark piece of pipeline positioning, rides and collapses on pipeline.An axle bed (2) is respectively welded on support centering both sides, the axis hole of two axle beds is on same center line, supporting the three-way axis (5) of "  " shape of relatively turnable being in the axis hole, the axle bed of schematic structure must could weld one after putting three-way axis, to be the requirement three-way axis can not deviate from the work rotation process purpose, can reach that three-way axis neither can be deviate from and purpose in relative rotation with other conventional Placement yet.The vertical section position of three-way axis is set with the axle sleeve (3) with handle (1) welding one, and both adopt running fit, and making axle sleeve is that any rotation motion is done in the axle center with the three-way axis vertical section, and the three-way axis top is fixing by nut (4).Like this, because handle and axle sleeve solid welding one are so handle can not only be done the revolution action around three-way axis, to realize pipe level position counterpart (Fig. 7-8), the while handle can also drive three-way axis and rotate up and down relative to support, to realize pipeline vertical position counterpart (Fig. 5-6).

The vertical counterpart of pipeline all be unable to do without the chain (6) that is connected with handle with horizontal counterpart, for this reason, have the handle head (8) of welding one on the handle, an end of chain is connected a side of handle head, opposite side is provided with chain locking slot (9), and the both sides of locking slot are upward bent stop hook (10).When the needs counterpart, support is shelved on the pipeline, with chain on another pipeline and be snapped into locking slot, because the existence of stop hook, when Joystick is done up and down or during left-right rotation, do when position adjust just hooked and more card more tight driving by another pipeline for chain, realizing two pipeline Vertical direction counterpart (Fig. 6) and substantially horizontal front and back counterpart (Fig. 8) up and down, thereby finishes the counterpart docking mission.

Claims

1. hinge type pipeline external clamp, comprise support (7) and chain (6), it is characterized in that described support is down " V " font, supporting relatively turnable three-way axis (5) in the support, be set with on the axle and handle (1) one and can rotating axle sleeve (3), nut (4) is fixed on the three-way axis top; Described chain is fixed on handle head (8) one sides with the handle one, and opposite side is provided with the stop hook (10) on chain locking slot (9) and locking slot both sides.

2. hinge type pipeline external clamp as claimed in claim 1 is characterized in that described three-way axis (5) is "  " shape, its two supports with the axle bed (2) of support one in.
