Background technology

In the processing of daily pipe prefabrication, often running into pipeline needs finished edge and tack-weld in advance, this just require pipeline group to the time, must be in same center, thus guarantee the axiality requirement of pipeline.While is owing to the diameter of pipeline in actual production often changes, thus the roller carriage of design, the positioning supports of the different-diameter pipeline that need when guaranteeing axiality, suit.

But conventional device is complex structure often, is not easy to install.

The utility model content

The utility model roller carriage technical problem to be solved provides a kind of self-centering pipeline support roller carriage, the location of the various diameter pipelines that can when guaranteeing axiality, suit.

The utility model solves the technical scheme that its technical problem adopted: a kind of self-centering pipeline support roller carriage is provided, comprises underframe, and a swing arm, No. two swing arms, leading screw, handwheel pressing plate and turning rolls etc.,

Described turning rolls comprises a swing arm, No. two swing arms, a bearing pin and No. two bearing pins; Occupy the turning rolls left side to being called two before and after the swing arm; No. two swing arms front and back are to being called right side, two turning rolls left sides; And two positions of No. two swing arms between two swing arms, two swing arms upper end all pass through the cooperation installation of bearing pin and deep groove ball bearing and are supportted material roller; Two swing arm lower ends all are installed on the briquetting through the cooperation between No. two bearing pins, pressing plate and the screw threes; Be connected with a little axle and No. two little axles between two swing arm stage casings respectively, a swing arm is connected through No. two dottle pins with No. two swing arms middle part crossover location;

Briquetting is installed on the underframe through the cooperation between screw, copper panel and No. two copper panel threes, and underframe is equipped with wheel through the cooperation between spacer, No. two spacers and the wheel shaft three on four angles all around;

Leading screw connects a little axle, No. two dottle pins and No. two little axles successively, and leading screw one end is equipped with the handwheel pressing plate.

The described wheel also is equipped with wheel cap.

Beneficial effect

The utility model roller carriage can be located when guaranteeing axiality in the support of suitable various diameter pipelines.
