Abstract
The utility model relates to a steel wire woven flame resistance protecting pipe for a connector, which is used in a fault early warning device of a coal mine hydraulic bracket. The utility model aimsat solving the technical problem of low intensity, poor bending resistance performance and the like of the existing protecting pipe in the prior art. In order to solve the technical problems, the steel wire woven flame resistance protecting pipe comprises a pipe wall, wherein the pipe wall comprises an inner rubber layer, an outer rubber layer and a middle framework layer. Because the utility model adopts the technical scheme, and the copper-plated steel wire framework layer is increased in the protecting pipe, the intensity and the bending resistance performance of the protecting pipe are greatly improved, cables in the protecting pipe are effectively protected from being damaged, and the utility model has important effect in the aspect of preventing the mine collapse, and favorably protects the personnel and life safety of underground operators.
Description
Technical field
The utility model relates to the connector cable protecting pipe that uses in a kind of coal mine hydraulic supporting fault pre-alarming device, specifically a kind of connector braided steel wire fire retardant jacket pipe.
Background technology
The colliery industry will be used coal mine hydraulic supporting fault pre-alarming device usually at present, and the critical component in this device is the connector cable protecting pipe, and transducer will be buckled in the protecting pipe two ends during use, plays a part very important to prevention mine landslide aspect.This protecting pipe is the General Purpose Rubber pipe at present, because down-hole service condition harshness, protecting pipe can often be subjected to the bump of external force, owing to do not have casing play in the protecting pipe, make relatively poor according to the intensity and the bending resistance of protecting pipe, cable in the protecting pipe also can often be subjected to the bump of external force and damage, and often causes cable short circuit, thereby can't play the effect of prevention mine landslide.
Summary of the invention
The purpose of this utility model is in order to solve technical problems such as existing protecting pipe intensity that prior art exists and bending resistance be relatively poor, and the high connector braided steel wire fire retardant jacket pipe of a kind of intensity height, the bending resistance that provide.
In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of connector braided steel wire fire retardant jacket pipe, it comprises tube wall, it is characterized in that: described tube wall comprises inner glue layer, outer glue-line and middle casing play.
In the further detailed structure of the utility model, also have following technical characterictic: described casing play is that the crisscross braiding of coppered steel wire forms.
In the further detailed structure of the utility model, also have following technical characterictic: the bonding strength of described inside and outside glue-line and casing play all 〉=2.5KN/M.
Compare with technology is originally arranged, the utlity model has following advantage and good effect:
Because the utility model has adopted technique scheme; in protecting pipe, increased the coppered steel wire casing play; make the intensity and the bending resistance of protecting pipe improve greatly; thereby protected the cable in the protecting pipe not to be damaged effectively; prevention mine landslide aspect is played a part very important, advantageously protected the personal life security of underground operators.
