Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

As shown in fig. 1-3, a large-scale pipeline welding bracket for municipal engineering comprises a sliding sleeve 1 and sliding rods 2, wherein two groups of sliding rods 2 are symmetrically distributed on two sides of the sliding sleeve 1, and the sliding sleeve 1 is in sliding fit with the sliding rods 2; the middle of the two groups of sliding rods 2 of the screw rod nut mechanism 3 is provided with the screw rod nut mechanism 3; the top of the sliding rod 2 on two sides of the sliding sleeve 1 is provided with an inclined bearing seat 4; the roller 5 is rotatably arranged on the inclined bearing seat 4 through a shaft pin.

The inclined bearing seats 4 and the rollers 5 are both arranged obliquely inwards, and the inclination angle is 10-25 degrees. Better strongly supporting the excircle of the pipeline.

The two sides of the sliding sleeve 1 close to the sliding rod 2 are provided with limiting blocks 11; the inner end part of the sliding rod 2 is provided with a stop block 21, and the stop block 21 is matched with the limit block 11 for limiting. Prevent the phenomenon that the bracket is separated due to excessive sliding distance,

the utility model discloses pipeline welding support, when pipeline welded connection, with the bottom of placing the support between two pipelines, utilize two sets of gyro wheels 5 of leanin to support, the contact form of pipeline and 5 periphery of gyro wheel is rolling friction, does benefit to the all-round rotatory welding that realizes the pipeline.
