Description

Novel small pipe assembling device

Technical Field

This novel group that belongs to is to the device, concretely relates to novel tubule group is to device.

Background

For the task that the diameter of a small pipe is mostly phi 6-phi 33.4mm and the receiving quantity is very large, the inner wall of the pipe is flush when the pipe is assembled to a circular welding line due to the requirement of pipeline construction, and the error variable is not more than 10% of the wall thickness, so the welding difficulty is very high. The concrete requirements are as follows: the error variable of the pipeline with the quality inspection grade I is not larger than 1mm, and the error variable of the pipelines with other grades is not larger than 2 mm. When the pipeline is paired, the straightness is measured at a position 200mm away from the center of the interface, and when the nominal diameter of the pipeline is less than 100mm, the allowable deviation is 1 mm. The corresponding openings are used for enabling the centers of the pipelines to be on a straight line. Most of industrial pipelines need nondestructive testing, and the quality of the nondestructive testing is directly influenced by the quality of the port.

General procedure for assembly of small tube sections: derusting within the range of 20mm at the two sides of the steel pipe interface until the derusting shows metallic luster, aligning the end parts of the two pipe sections on a platform, reserving a proper gap, spot-welding one point, checking the straightness at the other end by using a steel plate ruler, aligning by using a hand hammer, spot-welding one point after the steel pipe is qualified, repeating the steps, and firmly spot-welding the four central positions of the steel pipe, and then welding. The above steps are completed only by consuming much labor and time.

The construction process has the following problems:

(1) the assembly of the small pipe and the pipeline has a plurality of repeated steps, and tools such as a hand hammer, a ruler and the like are required to be used repeatedly;

(2) the group quality excessively depends on the operating level of operators;

(3) the method is time-consuming, labor-consuming, low in efficiency and low in speed, and the construction period is seriously influenced in the large-scale pipeline construction process.

Detailed Description

Novel tubule group is to device when using, only treats two by a staff and treats that the welded tubule puts into bottom plate V type groove, then clockwise rotation locking knob makes the pipe clamp compress tightly and treats the welded tubule, places the welding position in the middle of the bottom plate department, finally fixes two tubules, easy operation, and compares traditional handicraft and has reduced artificial waste. The fixed small pipe to be welded can not be displaced, so that the subsequent welding construction is facilitated, the adjustment work and the spot welding work in the manual assembly process are reduced, the time is saved, and the waste of materials such as welding materials, point fixing blocks and the like required in the spot welding process is also avoided. Meanwhile, the problem of pipeline deformation caused by spot welding by adopting the spot fixing block is avoided, heat generated in the welding process can be timely dissipated, deformation of the thin-wall small pipe due to heating is avoided, and the welding quality is guaranteed.

The bottom plate of the novel small pipe assembling device is positioned on the same plane, the V-shaped groove and the pipe clamp are also positioned on the same plane, the concentricity of the two small pipes to be welded is strictly ensured after the small pipes to be welded are fixed, and meanwhile, the misalignment of the small pipes during assembling meets the construction requirement that the misalignment does not exceed 10% of the wall thickness; the clamping end part of the pipe clamp adopts the arc-shaped groove, so that the pipeline is prevented from being damaged when the small pipe to be welded is clamped, and raw materials are saved to a certain extent; the fixed small pipe does not displace, the adjusted assembly gap is ensured not to change, and the welding precision and quality of the small pipe are directly ensured.

The novel small pipe assembling device mainly comprises four parts, a bottom plate, a pipe clamp, a locking pin and a locking knob, wherein the bottom plate is made of stainless steel plates, the pipe clamp is made of stainless steel pipes, and the locking pin and the locking knob are directly purchased to obtain finished products.
