Description

Technical Field

[0001] This utility model relates to the field of gas pipeline construction, specifically to a support device for large-span overhead gas pipelines. Background Technology

[0002] When supplying gas to urban gas users, some users are limited by conditions and their gas pipelines cannot be buried underground, requiring them to be laid overhead along the exterior walls of buildings. When overhead gas pipelines cross roads that are passable by vehicles, their height must be greater than 4.5 meters, and the spacing between the two supports must meet the pipeline span requirements, while ensuring safety. Sometimes, because the road width exceeds the pipeline span requirements, the spacing between supports on both sides of the road (located on buildings) cannot meet the needs. In such cases, long supports or pillars are generally used to solve the problem. Long supports are generally used when the width needs to be increased by within 1 meter; they cannot solve the problem for excessively wide roads. Pillars can solve the problem, but they need to be placed in the middle of the road to meet the requirements, which can affect vehicle traffic and create safety hazards. Furthermore, the height of the pillars results in a larger space requirement. Summary of the Invention

[0003] This invention addresses the problem that when overhead gas pipelines cross roads, the road width exceeds the required span of the gas pipeline, necessitating the installation of support points in the middle of the road to meet the pipeline span requirements. It provides a support device specifically for overhead gas pipelines with large spans.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a support device for a large-span gas overhead pipe, including a six-hole half-joint clamp and two fixed supports. The holes at the upper ends of the left and right sides of the six-hole half-joint clamp are connection holes, and the remaining holes are bolt connection holes. Each set of bolt connection holes is fitted with a bolt. The connection holes on the left and right sides are respectively connected to the two fixed supports by steel wire ropes. The steel wire ropes pass through the connection holes or bend at the rear end of the fixed supports and are fixed by steel wire rope clips.

[0005] Furthermore, the fixed bracket is a right-angled tripod, with one right-angled frame fixed to the wall and the other right-angled frame used to connect to one end of the steel wire rope.

[0006] Furthermore, the wire rope clip includes a U-bolt and a clip holder, with a nut screwed onto the end of the U-bolt.

[0007] Furthermore, the wire rope passes through the connecting hole or the rear end of the fixing bracket, is bent, and is fixed by three wire rope clips arranged at least at equal intervals.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] By installing a six-hole half-clamp on the outer side of the gas pipeline in the middle of the road, and setting fixed supports on the buildings on both sides, the six-hole half-clamp is connected to the fixed supports on both sides by steel wire rope (diagonal bracing), which serves to support the overhead pipeline.

[0010] Compared with setting up pillars in the middle of the road, the support device of this utility model has the following advantages: 1. It does not occupy road space, does not affect vehicle traffic, reduces traffic accidents, and ensures the safe operation of pipelines; 2. It is simple and has low cost.

[0011] Compared with long supports, the support device of this utility model has the following advantages: 1. It solves the problem of larger spans in gas pipelines. 2. The support device of this utility model is relatively more stable. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments. Example 1

[0020] like Figure 1 and 2 As shown, a support device for a long-span overhead gas pipeline includes a six-hole split clamp 5 and two fixed supports 2. The holes at the upper ends of the left and right sides of the six-hole split clamp 5 are connecting holes 7, and the remaining holes are bolt connecting holes 6. Each set of bolt connecting holes 6 is fitted with a bolt 8. The connecting holes 7 on the left and right sides are connected to the two fixed supports 2 by steel wire ropes 4. The steel wire ropes 4 pass through the connecting holes 7 or bend at the rear end of the fixed supports 2 and are fixed by steel wire rope clips 3.

[0021] By installing a six-hole half-clamp on the outer side of the middle of the gas pipeline 1, and setting fixed supports 2 on the buildings on both sides, the six-hole half-clamp 5 is connected to the fixed supports 2 on both sides by steel wire rope 4 (diagonal bracing), which serves as a support for the overhead pipeline.

[0022] Furthermore, the fixed bracket 2 is a right-angled tripod, with one right-angled frame fixed to the wall and the other right-angled frame used to connect to one end of the steel wire rope 4.

[0023] Furthermore, the wire rope clip 3 includes a U-bolt 3-1 and a clip seat 3-2, with a nut screwed onto the end of the U-bolt 3-1.

[0024] Furthermore, the steel wire rope 4 passes through the connecting hole 7 or the rear end of the fixing bracket 2, is bent, and is fixed by three steel wire rope clips 3 arranged at least at equal intervals.

[0025] When gas pipelines are laid overhead on building walls, the fixed supports 2 are fixed to the building walls. Bolts 8 are used to secure the bolt holes 6 of the six-hole clamp 5, fixing the clamp 5 in the middle of the gas pipeline 1. One end of the wire rope 4 is looped around the remaining two connecting holes 7 on the six-hole clamp 5. Then, a U-bolt 3-1 is fastened to the end of the wire rope 4, and the wire rope clip 3-2 is fastened to the working section of the wire rope 4. The end of the wire rope 4 is secured by tightening the nut matching the U-bolt 3-1. The other end of the wire rope 4 should loop around the supporting angle steel of the fixed support 2. Using the same method, the other end of the wire rope 4 is secured to the fixed support 2 using U-bolts 3-1. The number of wire rope clips 3 should be determined according to the diameter of the wire rope 4. The U-bolts 3-1 and wire rope clips 3-2 are tightened periodically to prevent loosening. In this way, the gas pipeline 1 is connected to the fixed support 2 by the steel wire rope 4, and the diagonal tension of the steel wire rope 4 provides support for 1.
