Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A cross-over joint for cable protection pipe, comprises interior pipe 100, first outer tube 200 and the second outer tube 300; Described interior pipe 100 comprises pipe 101, first inclined tube 102 and the first intubate 103 in first; Described first taper of inclined tube 102 in hollow, the osculum end of described first inclined tube 102 connects pipe 101 in first, and the big opening end of described first inclined tube 102 connects the first intubate 103; The inwall of described first intubate 103 is embedded with the first snakelike heating wire 104; Described first outer tube 200 comprises pipe 201, second inclined tube 202 and the second intubate 203 in second; In described second, in pipe 201 and first, pipe 101 concentric is arranged; Described second taper of inclined tube 202 in hollow, the osculum end of described second inclined tube 202 connects pipe 201 in second, and the big opening end of described second inclined tube 202 connects the second intubate 203; The inwall of described second intubate 203 is embedded with the second snakelike heating wire 204; In described second, one end of pipe 201 is connected to the outer wall of the first inclined tube 102; In described second, pipe 201 is connected with the second outer tube 300.
Interior pipe 100 is in order to import the cable on major trunk roads, and the second outer tube 300 is in order to the cable of access tributary.The cable of the branch gap entered in pipe in first 101 and second between pipe 201 enters the major trunk roads of electric cable transporting pipeline.The setting of the first inclined tube 102 and the second inclined tube 202, makes the diameter of the first intubate 103 and the second intubate 203 be greater than cable protection pipeline on major trunk roads, facilitate the first intubate 103 and the second intubate 203 insert respectively before and after cable protection pipeline.
During installation, first the first intubate 103 is sheathed on the cable protection pipe of upstream, then conducting first heating wire 104, first heating wire 104 generates heat, and makes the first intubate 103 and upstream cable protection pipe hot-melt adhesive paste.Then the second intubate 203 is sheathed on the cable protection pipe in downstream, conducting second heating wire 204, second heating wire 204 generates heat, and makes the cable protection pipe hot-melt adhesive paste in the second intubate 203 and downstream, now, and this cross-over joint access cable backbone road.
This cross-over joint have employed hot-melt adhesive paste with the connected mode of cable protection pipe, compared to traditional bonding or mechanical connection, has and installs the advantage convenient, anti-permeability is good.
The outer wall in described first, pipe 101 being positioned at the second side, outer tube 300 downstream is provided with the projection 105 of one group of spaced radial direction arrangement; The inwall in described second, pipe 201 being positioned at the second side, outer tube 300 downstream is provided with the groove 205 of one group of spaced radial direction arrangement; Described protruding 105 are embedded at corresponding groove 205.
Because the branch cable imported from the second outer tube 300 enters major trunk roads from a hole, in order to avoid gathering of branch cable, by being distributed in uniformly by branch cable by the gap of pipe 201 in pipe in separate by protruding 105 first 101 and second, make branch cable evenly can pass into the major trunk roads in downstream.
A cross-over joint for cable protection pipe, also comprises end cap 400; Described end cap 400 comprises end cap 401, first sleeve 402 and the second sleeve 403; Described first sleeve 402 and the second sleeve 403 concentric are arranged at end cap 401 side; The diameter of described first sleeve 402 is less than the diameter of the second outer tube 300; The diameter of described second sleeve 403 is greater than the diameter of the second outer tube 300.
The length of described first sleeve 402 is not less than 2cm; The length of described second sleeve 403 is not more than 1.5cm.
When branch cable does not import, end cap 400 plays the effect of a provisional protection.Covered by end cap 400, be the second sleeve 403, second outer tube 300 and the first sleeve 402 successively in falling outward, form tortuous loop each other, the dirt sand that can effectively intercept in external environment condition enters cross-over joint inside.
The utility model is illustrated according to embodiment, and under the prerequisite not departing from present principles, this device can also make some distortion and improvement.It should be pointed out that and all drop on the technical scheme that all employings are equal to replacement or the mode such as equivalent transformation and obtain in protection range of the present utility model.
