Abstract

The utility model relates to a socket type multi-hole prism cable tube. A tube body comprises a prism tube body, tube ends, tube ribs/outer ribs, tube ribs/inner ribs, and a plurality of tube holes/ sub-holes; at any tube end of the tube body, a socket sleeve/ a polygonal socket sleeve and socket hole/ a polygonal socket hole are arranged; the tube end is made into a socket end; and the multi-hole prism tube body is made into a socket type multi-hole prism tube body. In the technical proposal, the outer wall of the outer rib at the tube end is connected/welded with the inner wall of the socket sleeve at the socket end, so that the cable tube needs no pipe connecting sleeve; the number of connection is obviously reduced; the cable tube has high-strength welding property, large welding surface, and good solidness; and tube holes/sub-holes can not shrink or be blocked, and the sub-holes can not be in wrong connection when the cable tube is welded. Therefore, the utility model saves production materials of pipe connecting sleeves, facilitates the buried construction of cable tubes, and has positive effects on improving the cable tube, and perfecting and normalizing the production technology.

Description

Socket porous prismatic cable tube

Technical field:

The utility model relates to the telecommunications equipment, is particularly useful for protecting the buried pipeline of power cable and telecommunication cable.

Background technology:

Traditional cable tube, its tubing, press the peripheral shape of pipe shaft, divided cylinder cable tube and prismatic cable tube have been arranged, by what of the pore quantity that on body, is provided with, having divided has single hole cable tube and porous cable pipe, presses the shape of body end face, and having divided has plum blossom shape cable tube, cellular cable tube, grid-like cable tube etc.The cylinder cable tube, the peripheral shape that refers to pipe shaft is the body of cylindrical shape; Prismatic cable tube, the peripheral shape that refers to pipe shaft is the body of polygon cylinder.On body, only be provided with the tubing of a pore, be the single hole cable tube, as single hole cylinder cable tube, the prismatic cable tube of single hole; At the tubing that is provided with sub-hole more than two (containing two) on the same body, be porous cable pipe, as the prismatic cable tube of plum blossom shape porous/cylinder cable tube, cellular porous prismatic cable tube/cylinder cable tube, the prismatic cable tube of grid-like porous/cylinder cable tube etc.The pore that a plurality of sub-holes are arranged, also difference is sub-hole, limit, neutron hole mutually.

The raw material of producing cable tube is engineering plastics.Because the pvc pipe material, though the tool high-intensity performance, can not welding, so, produce the cable tube that does not require welding, generally adopt PVC modified (PVC) material.Since PE tubing, the energy welding, and intensity but there is not the pvc pipe material good, so the cable tube of production requirement welding generally adopts polythene material (PE) or polyethylene modified material (PPR).

Because traditional cable pipe product, in production procedure by fixed length directly from make-up machine take off, two pipe ends and the same straight wall type tube material of end surface shape, so, when cable tube is constructed with burying, each connects at the insertion tube two ends that connect cover opposite to each other with a pipe end with two cable tubes, perhaps, with the end face welding in opposite directions of pipe end.This cable tube structure that needs the adapted pipe to connect cover: not only obviously wasted pipe and connect cover material, and cable tube of every connection need engage twice, construct to cable tube with burying and brought inconvenience and increased workload; During directly with two end face welding cable tubes, can cause pore/sub-hole to dwindle phenomenon, serious, also can cause pore/sub-hole plug.

For improving the urban road environment, power circuit is built on stilts will change into without exception into lay, the city cable pipe is constructed with burying again, can not tackle the river course, interrupt urban transportation, so, with the extensive use of non-excavation underground cable plumber journey technology in urban road and river bed pipe laying engineering construction, to the cable tube specification requirement risen to should high strength the aspect of weldable again.

As seen, market and cable tube manufacturing enterprise, the cable tube product that all be sought after a kind ofly needn't the adapted pipe connecing cover and also can interconnect/welding and more conveniently connecting/welding, that can obviously reduce cable tube junction quantity, has high strength and weldable performance.

Summary of the invention:

The purpose of this utility model, be form and provide a kind of neither need the adapted pipe to connect cover and can obviously reduce cable tube junction quantity, weldable but can not cause pore/sub-hole to dwindle cable tube product with blockage structure again.

The utility model provides a kind of socket porous prismatic cable tube, and its scheme is such: the prismatic body of porous body/porous, form by pipe shaft/polygon pipe shaft, pipe end/polygon pipe end, pipe muscle, a plurality of pore/sub-hole; Arbitrary pipe end at pipe shaft, be in the junction of socket joint cover with the pore mouth with pipe muscle/outer muscle, socket joint hole/polygon socket joint the hole that socket joint cover/polygon socket joint cover is set and surrounds by socket joint cover inwall, pipe end/polygon pipe end is formed bell end/polygon bell end, the prismatic body of porous body/porous is formed the socket porous prismatic body of socket porous body/polygon.

Owing to adopted such scheme, set up socket joint cover/polygon socket joint cover and socket joint hole/polygon socket joint hole at arbitrary pipe end of pipe shaft, interconnect/welding with the outer muscle outer wall of pipe end socket joint cover inwall with bell end, concentrate solved needn't the adapted pipe connect cover, obviously reduce cable tube junction quantity, possess that high strength weldable performance, the big fastness of face of weld are good, can not cause pore/sub-hole to dwindle during welding or stop up and sub-hole can not take place be connected a series of technical barriers such as inconsistent phenomenon.Thereby,, saved pipe and connect cover and produce material, reduced cable tube and bury the ground engineering cost connecing cover by the adapted pipe; With obvious minimizing cable tube junction quantity, made things convenient for cable tube to construct with burying, reduced workload; With weldable, strengthened face of weld, strengthened welding fastness and sealing, ensured that cable tube buries the ground project quality; Combine with the application of socket fitting type structure, make the cable tube product possess high strength weldable performance with high strength weldable material.This technical scheme to promoting the cable tube product, improving and standard cable tube technology, all has positive effect.
