Description
Technical field
The utility model relates to a kind of rubber short tube that is installed between the two joint steel pipes, specifically, is a kind of shield machine yielding rubber short tube.
Background technique
Carry out tunnel construction with shield machine and have plurality of advantages: the automaticity height, save manpower, speed of application is fast, weatherproof, face sedimentation controllably reduces the influence to above ground structure.The shield machine technology is by more and more widely utilization.The dregs that shield machine excavates under the effect of slurry pump, is delivered to outside the hole by pipeline.This pipeline, it is alternate to be generally long metal tube and rubber short tube, and by the energy-absorbing function of rubber short tube, the buffering metal tube is flexible, swing the stress that produces.
Yielding rubber short tube present and that shield machine is supporting generally is drum type, and inner and outer diameter all is small in ends, broad in the middle, and tube wall is also very thin, and mutability can produce damping effect preferably.
But this drum type structure, the inner cavity of pipe unevenness has some setbacks, and when material passes through, can produce eddy current, and rapid worn out tube wall causes shut-down, and progress delays the project.The existence of eddy current has also increased Transport resistance, has caused too much power consumption.
Summary of the invention
For overcoming the deficiency that prior art exists, the purpose of this utility model is to provide a kind of shield machine yielding rubber short tube, this yielding rubber short tube not only has good damping performance, and has a good abrasion resistance, be suitable for the hard material of transporting large particle, and pipeline is unobstructed, and transporting resistance is little.
The purpose of this utility model is achieved through the following technical solutions.
A kind of shield machine yielding rubber short tube comprises body and the flange that is arranged on the body two ends, it is characterized in that this rubber short tube comprises inside liner, enhancement layer and outer covering layer from inside to outside successively; Post one group of wear-resistant ceramic at the liner surface lining; Be provided with rubber ring between inside liner and the enhancement layer; Inside liner, enhancement layer and outer covering layer all extend to the flange position, are provided with the annular metal sheet that is embedded in the sizing material at the flange place of body one end; Inside liner, enhancement layer and outer covering layer all are connected with annular metal sheet; Flange at the body the other end is reduced into baffle ring, is provided with mobilizable metal flange at the baffle ring place, and this metal flange edge is provided with the flange suitable with baffle ring, and metal flange is connected with body with baffle ring by flange.
In the utility model, annular metal sheet surface-coated adhesive, annular metal sheet is by sulfuration and sizing material good bond on every side.The wear-resistant ceramic surface also scribbles adhesive, by sulfuration and inside liner sizing material good bond.The wear-resistant ceramic surface configuration is plane or convex surface.
Between inside liner and enhancement layer, be provided with one group of rubber ring in the utility model.
To strengthen the damping performance of pipeline.
In the utility model, there are a plurality of annular metal sheets at the flange place at body one end.The annular metal sheet surface scribbles adhesive, by the sizing material good bond of sulfuration and inside liner and outer covering layer.Except having a surface exposes with bonding 1 sheet metal of outer covering layer, remaining sheet metal all buries in sizing material.
In the utility model, there is screw at an end flange position, is connected with other pipelines by bolt; The other end flange position dwindles into baffle ring, and other establishes a mobilizable metal flange, on screw is arranged, be connected with other pipelines by bolt.
Compared with prior art, the utlity model has good damping performance, also have good abrasion resistance simultaneously, be suitable for transporting large particle hard dregs; And tube chamber is unobstructed, and the transporting resistance is little, can be energy-conservation.The utility model one end is provided with movable flange plate, and it is very convenient to carry out fitting operation, can be relatively easy to be installed on the shield machine between two metallic conduits, carries various materials under working pressure.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of shield machine described in the utility model yielding rubber short tube is seen Fig. 1.Comprise body 11 and the flange that is arranged on body 11 two ends, body 11 comprises inside liner 1, enhancement layer 2 and outer covering layer 3 from inside to outside.Inside liner is made of abrasion resistant compound, and enhancement layer is made of the fiber cord fabric of kiss-coating, and outer covering layer is made of abrasion performance and ageing-resistant sizing material.The liner surface lining posts polylith wear-resistant ceramic 4, makes pipeline be suitable for carrying the hard materials of large particle such as rubble.Several roads rubber ring 5 is arranged, in order to strengthen the damping performance of pipeline between inside liner and the enhancement layer.Inside liner 1, enhancement layer 2 and outer covering layer 3 all extend to the flange position, being provided with several sections with flange 12 positions or all burying annular metal sheet 6 in sizing material at body 11 1 ends.Be provided with screw at flange 12 positions, be connected with other pipelines by bolt; Dwindle into baffle ring 13 at body 11 the other end flange positions, other establishes a mobilizable metal flange 7, on have and connect screw 8, be connected with other pipelines by bolt.
The flange position is material of main part with the sizing material, makes skeleton with annular metal sheet, and is soft outside but hard inside, can form the pipeline of good airproof performance with steel pipe.This flange arrangement and be sandwiched in inside liner 1 and enhancement layer 2 between rubber ring 5 make pipeline have good damping performance.The polylith wear-resistant ceramic 4 that inside liner 1 surface lining pastes makes pipeline have good abrasion resistance, is suitable for the hard materials of large particle such as transporting rubble.The utility model inner chamber is unobstructed, and the mass transport resistance is little, can save construction power.
