Description

Detachable insulation support

Technical Field

The utility model relates to an insulating sleeve, in particular to a detachable insulating sleeve for wrapping an overhead pipeline.

Background

The engineering of 'coal changing gas' in rural areas is an important civil engineering, and along with the increase of the national environmental protection, the engineering of 'coal changing gas' clean energy conversion is actively developed in rural areas, so that the engineering plays a positive role in national environmental management, improvement of living environment of rural people and driving of rural economic and social development. At present, except buried laying, the gas pipeline of 'coal to gas' mostly adopts an overhead laying installation mode, and the electric wires and cables which are obviously installed in villages are more along the outer wall, and have different degrees of intersection with the gas pipeline, so that the standard safety distance requirement is not met. In the prior art, before the connection of a gas pipeline, if the phenomenon of crossing with an electric wire or a cable exists, an insulating sleeve is penetrated on the gas pipeline in advance; however, different open-mounted electric wires and cables can be added on the village wall along with the time lapse and the construction of 'beautiful villages', potential safety hazards are left for the normal operation of the gas pipeline, and in order to ensure the safe operation of the pipeline, after the installation of the overhead pipeline is finished, if the open-mounted electric wires or cables are crossed or wound with the pipeline, an insulating sleeve needs to be added, so that the safe distance between the gas pipeline and the electric wires and cables is ensured.

Traditional insulation support is a whole circular sleeve pipe, need can install additional to half cutting the rear to the overhead pipeline on, adopts the bandage again or ties up the silk and fix, and the construction operation is inconvenient, and is fixed insecure, iron wire or bandage fracture back, the sleeve pipe will drop automatically, influences the safe operation of gas pipeline.

Disclosure of Invention

In order to overcome the defects that the existing sleeve is inconvenient to safe and easy to fall off to influence the safe operation of a gas pipeline, the utility model provides the detachable insulating sleeve which can be installed before pipeline connection and can also be installed after pipeline connection, so that the problem that the pipeline is not cut or blocked compactly is reduced, the construction progress is accelerated, and the potential safety hazard is reduced.

The technical scheme adopted by the utility model for realizing the purpose is as follows:

the utility model provides a detachable insulation support, presss from both sides including the two halves that are used for parcel overhead pipeline, and the both sides that the two halves pressed from both sides are equipped with detachable construction respectively, detachable construction presss from both sides on one side including establishing respectively at the two halves along transversely being equipped with respectively through the dop of bolt fastening, and the two halves presss from both sides the opposite side outside and evenly is equipped with the parcel dead lever and passes through rivet connection's mounting.

Furthermore, the fixing piece comprises a bulge which is arranged in the center and used for wrapping the fixing rod, fixing pieces which are tightly attached to the two half clamps are arranged on two sides of the bulge, and the fixing pieces are fixed on the half clamps through rivets.

Preferably, the inner diameter of the insulating sleeve composed of the two half clamps is larger than the outer diameter of the overhead pipeline by more than 100 mm.

Preferably, the two half clamps and the overhead pipeline are filled and sealed by adopting foaming glue.

Preferably, the two halves of the clip are semi-circular.

Further, flanges for connecting the two insulating sleeves are connected to two ends of the two half clamps.

Preferably, the clamping heads and the fixing parts are arranged in a plurality and are transversely and uniformly distributed on the two half clamps.

The utility model provides an insulating sleeve capable of being freely disassembled and assembled, which can be assembled before the connection of a gas pipeline is finished, and can be additionally assembled after the connection of the pipeline is finished, so that the insulating sleeve does not need to be cut, and the construction links are reduced; the safety space of the standard requirement can be met, the construction progress can be accelerated, and the method has the advantages of convenience in installation, high construction speed and the like.

The insulating sleeve is in a cylindrical hollow structure, mainly comprises two half clamps which are semicircular rings, wherein one ends of the two half clamps are clamping heads and are fixedly butted by bolts and nuts, the other ends of the two half clamps are clamping tails and are fixedly connected by rivets, the upper half clamp and the lower half clamp can be freely turned up and down, and the material of the upper half clamp and the lower half clamp is polyvinyl chloride. The installation of the overhead pipeline can adopt a novel insulating sleeve, the specification of the sleeve is determined according to the pipe diameter of the gas pipeline, the inner diameter of the general insulating sleeve is more than 100mm larger than the outer diameter of the gas pipeline, and the sleeve is filled and sealed by adopting foaming glue; if the length of the gas pipeline is long and the sleeve is short, the two sleeves can be connected by flanges. By adopting the sleeve, the sleeve can be installed before the overhead gas pipeline is connected, and also can be installed after the gas pipeline is connected, so that the condition that the cable is wound again and the sleeve cannot be installed after the gas pipeline is installed is avoided, the occurrence of the condition is effectively solved, and the safety interval requirement of the gas pipeline is ensured.
