Boiler pressure pipeline welding stable structure

Technical Field

The utility model relates to the field of boiler pressure pipelines, in particular to a stable welding structure for a boiler pressure pipeline.

Background

When boiler pressure pipeline welds, need fix boiler pressure pipeline position, current fixed mode still adopts staff's hand rest and plate to support the mode, though these modes can support boiler pressure pipeline, nevertheless, are difficult to fix its position, and then lead to boiler pressure pipeline welding to go on difficultly. In view of this, we propose a boiler pressure pipeline welding stable structure.

Detailed Description

Referring to fig. 1-5, the present invention provides a technical solution:

the utility model provides a boiler pressure pipeline welding stable structure, includes base 1, and first recess 6 has been seted up to 1 upper end of base, rotates in the 1 inner chamber of base and installs the first splint 5 that are bilateral symmetry and set up, and first splint 5 matches with first recess 6, and slidable mounting has screw block 8 in two

first splint

5, 1 internal rotation of base install with two screw block 8 screw-thread fit's first threaded rod 3.

Specifically, a cavity 10 matched with the thread block 8 is formed in the first clamping plate 5, limiting slide rails 11 are arranged on the front side and the rear side of the cavity 10, and cylindrical slide blocks 9 connected with the limiting slide rails 11 in a sliding manner are fixed at the front end and the rear end of the thread block 8; the movement direction of the thread block 8 can be limited, and the thread block 8 can drive the first clamping plate 5 to rotate.

Further, two second grooves 7 which are symmetrically arranged in the front-back direction are formed in the upper end of the base 1, and two second clamping plates 4 which are symmetrically arranged in the left-right direction are slidably mounted in the second grooves 7; the pressure pipeline can be clamped and fixed on the left side and the right side.

Furthermore, a second threaded rod 2 which is in threaded fit with second clamping plates 4 on the left side and the right side is rotatably arranged in the base 1; so as to drive the second clamping plates 4 at the left and right sides to move.

Furthermore, the front side and the rear side of the second clamping plate 4 are provided with limiting sliding chutes 12 which are in sliding connection with the front inner wall and the rear inner wall of the second groove 7; the direction of movement of the second clamping plate 4 can be limited.

The working principle is as follows: when the pressure pipeline welding device is used, a pressure pipeline to be welded is placed at the upper end of a base 1, first threaded rods 3 are rotated at the left end and the right end of the base 1, the rotated first threaded rods 3 drive threaded blocks 8 at the left side and the right side to oppositely move through threads symmetrically arranged on the periphery of the rotated first threaded rods 3 in the left-right direction under the limitation of a limiting slide rail 11 and a cylindrical slide block 9 on the moving direction of the threaded blocks 8, the threaded blocks 8 which oppositely move can drive first clamping plates 5 at the left side and the right side to oppositely rotate under the limitation of the limiting slide rail 11 and the cylindrical slide block 9 on the moving direction of the threaded blocks 8, the pressure pipeline can be limited at the left side and the right side of the lower end, and the height of the pressure pipeline can be adjusted through the adjustment of the angle between the two first clamping plates 5;

both ends about base 1 rotate second threaded rod 2, and under the restriction of second splint 4 direction of motion at spacing spout 12 and second recess 7, pivoted second threaded rod 2 drives left and right sides second splint 4 relative motion through the screw thread that its periphery bilateral symmetry set up, carries on spacingly to pipeline under pressure in the left and right sides, cooperates two first splint 5, can carry out the centre gripping to pipeline under pressure fixed.
