Abstract

A combined pipe clip, including a upper pipe clip with a arc surface, a lower pipe clip with a arc surface, two bolts and a base; the lower pipe clip is clipped on the base, two bolts extend from the base and be connected with the upper and lower pipe clips and then be fixed by nuts; an adjusting clearance between a screw and a bolt of the upper pipe clip. Owing to the lower pipe clip is clipped on the base, and an adjusting shim can be arranged between the base and the lower pipe clip according to practical need, so the lengthways error of the pipeline can be adjusted by regulating the thickness of the adjusting shim, and the manufacturing error of the pipeline can be compensated by making use of a red copper gasket so as to increase the contact area between the pipeline and the pipe clips; in addition, the error brought about by the deflective centerline can be adjusted by means of the adjusting clearance between the screw and the bolt of the upper pipe clip so as to carry through an omni-directional accommodation of error adaptability of the pipeline.

Background technique

The installation of metal such as air conduit, oil transport pipeline or plastic cement pipe fitting needs pipe clamp to fix on electric locomotive, internal combustion locomotive and the vehicle.Common pipe clamp is " U " shape, be stuck on the pipeline and pass through bolt, though common pipe clamp is relatively simple for structure, but pipeline exists in installation process because of making, install the error that is caused, common pipe clamp can't be made accommodation, adopts the existing allotment of labor of pipe clamp to plant on the pipeline of mode so common pipe clamp only is used in.China Patent No. is the clamping fixing device of 200420035101.4 the disclosed a kind of pipeline of utility model patent specification, it has last pipe clamp body and following pipe clamp body, last pipe clamp body all has the semicircle cambered surface with following pipe clamp body, last pipe clamp body matches with following pipe clamp body and forms the arc surface of double team pipe fitting, have bolt hole on last pipe clamp body and the following pipe clamp body, clamping bolt will be gone up pipe clamp body and link together with following pipe clamp body.Though above-mentioned the utility model has the reliable advantage of clamping, the same accommodation of the deficiency can't make to(for) the error on the pipeline that exists.

The model utility content

The purpose of this utility model is to propose a kind of accommodation of combined type pipe clamp can make to(for) the error on the pipeline.

The utility model comprises upper and lower pipe clamp and two bolts with arc shaped surface, for achieving the above object, this combined pipe jig has base, described pipe clamp down is sitting on the base, two bolts stretch out from base and connect down pipe clamp and last pipe clamp and fixed by nut, have the adjusting play between the above-mentioned screw of going up pipe clamp and bolt.

Be provided with the adjustment pad that two bolts therefrom pass between described base and the following pipe clamp.

Described adjustment pad is provided with two openings that are on the same side, and two bolts pass from each corresponding opening.

This pipe clamp has and fills up between last pipe clamp and the pipe red copper pad in use and fill up in use at the following red copper pad between pipe clamp and the pipe down.

The described wide main body in bottom of pipe clamp down for top; The described two ends, the left and right sides of the bottom of pipe clamp down are forked, and following pipe clamp is between two bolts by the two ends on its base are forked.

One side of described base is provided with two up-small and down-big stepped shaft openings, and the head of bolt inserts in the opening.

Described bolt is the bolt of forming surface head.

The screw thread of described bolt is a fine thread.

The utlity model has following characteristics:

1, the utility model is owing to following pipe clamp is sitting on the base, has the adjusting play between the screw of pipe clamp and bolt in the utilization, adjust the crooked and error that causes in the pipeline center line left and right sides, between base and following pipe clamp, can be provided with the adjustment pad as required, utilize to adjust the thickness of pad and adjust the existing error of pipeline above-below direction, reach for the error adaptability on the pipeline make the purpose of comprehensive adjustment.

2, the structure of the utility model part, shape all make things convenient for installation, and adopt two bolt, nut to be in the top again, so assemble, check all very convenient.

3, the utility model can directly be born by bolt for the power of the above-below direction that is subjected to, thus stressed simple, can directly pipe be fixed on the body framework, bring convenience to use.

4, the utility model can increase the area of contact of pipe clamp and pipeline to greatest extent owing to the existence of red copper pad, reduces the localized stress of pipe clamp and pipeline contacting point pipeline, and utilizes frictional force to bear reliably along the power of pipeline axial direction.

5, the utility model adopts bolt of serration, and anti-loosening property is good, and the antivibration ability is strong.
