The special fast-escape car of a kind of escape tube
Technical field
The invention belongs to mining tunnel field of engineering technology, relate to personnel escape's pipe in tunnel and tunnel, the special fast-escape car of especially a kind of escape tube.
Background technology
The tunnel in tunnel and mine is in work progress, and due to the impact by complicated geology and other factors, happen occasionally landslide phenomenon, and landslide phenomenon of wherein closing the door consequence is the most serious, once there is the life security that will have a strong impact on in-cavity construction personnel.Therefore, for the phenomenon of caving in tunnel, constructing tunnel, for avoiding personnel casualty accidents as far as possible, reducing unnecessary economic loss, carrying out the setting of tunnel pipe for escaping, seem extremely important.
According to domestic associated documents requirement, tunnel V level country rock paragraph and be in the extremely high risk location of landslide and other locations when enclosing rock measure adds up to deform more than 100mm through risk assessment, must pipe for escaping be set, to guarantee the personal safety of constructor in tunnel excavating process.Safe step pitch between secondary lining and face, between face distance inverted arch must not be greater than the distance of design and regulation and stipulation.Between tunnel tunnel face and secondary lining, should arrange pipe for escaping, along with excavation drilling depth constantly moves forward, pipe for escaping distance excavation face should be not more than 20m, stretches into and applies inverted arch section and must not be less than 5 meters.
When having an accident, although staff escapes by escape tube, but existing escape tube is all used by large-diameter pipe mostly, escape personnel is when escaping, make to form longer shiny surface in escape tube because escape tube may be formed to tilt forward and back to tilt, escape personnel possibly cannot realize escaping voluntarily; In addition, the accident of generation may cause injury to personnel and the situation that cannot escape voluntarily.Therefore, existing escape tube is difficult to " escape " that really realize staff.
By retrieval, do not find any scientific and technical literature of the escape car being exclusively used in escape tube.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, provide a kind of and effectively can ensure the special fast-escape car of the escape tube of all kinds of escape personnel's fast-escape.
The technical scheme that technical solution problem of the present invention adopts is:
The special fast-escape car of a kind of escape tube, comprise flat board and to go to the bottom the roller that both sides install at flat board, flat board installed roller of going to the bottom is two rows, it is characterized in that: described flat board is strip, colligation through hole is shaped with in the bilateral symmetry of flat board, flat board is shaped with tractive through hole, and flat board goes to the bottom installed roller for combination roller.
And described flat board goes to the bottom installed roller for combination roller, is namely all provided with a centripetal inclined wheel in the outside of each roller.
And, in one end of flat board by automatic turning gemel connection one returning face plate, returning face plate is shaped with tractive through hole.
And the structure of described automatic turning hinge is: be set with a spring on the bearing pin of hinge, the bearing pin of the both sides up and down of spring is set with hinge.
Of the present inventionly with good effect be a little:
1, this escape car adopts plate armature, can maximum minimizing take up space, and be shaped with colligation through hole in dull and stereotyped both sides, tractive through hole is shaped with in both sides, front and back, roller is fixedly mounted with in flat plate bottom both sides of the edge, be formed in escape tube thus and run unobstructedly, realize fast by escape personnel by external force tractive accidents happened district.
2, this escape car goes to the bottom installed roller for combination roller at flat board, wherein vertically roller can realize running in escape tube fast, vertically the outside of roller is then provided with centripetal inclined wheel, still can smooth and easyly run when can realize escape tube distortion or the inclination of tractive flat board, ensure that escape car reliability of operation, improve the operational efficiency of escape car.

Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the invention will be further described, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
The special fast-escape car of a kind of escape tube, comprises dull and stereotyped 2 and to go to the bottom the roller 5 that both sides install at flat board, dull and stereotypedly adopts high-strength high rigidity plastic production, and flat board installed roller of going to the bottom is two rows.
Innovative point of the present invention is:
1, described flat board is strip, is convenient to human body and couches.The flat board of the head position couched at human body connects a returning face plate 1 by automatic turning hinge 7, the effect one of this returning face plate is to lengthen dull and stereotyped length, and there is certain damping property, also can pass through upset simultaneously and realize folding with dull and stereotyped, be convenient to transport to make length reduction.In the structure of automatic turning hinge see Fig. 5, the bearing pin 11 of hinge is set with a spring 12, the bearing pin of the both sides up and down of spring is set with hinge.
Also can not returning face plate be set, and refers to directly adopt single flat board.
2, the bilateral symmetry of described flat board is shaped with colligation through hole 8, and this colligation through hole is built in the abdominal region of the human body that couches; Tractive through hole 6 and rear tractive through hole 9 before the outer end medium position of the front end of flat board and returning face plate is shaped with respectively, these two tractive through holes be used for fast by escape personnel by external force tractive accidents happened district.
3, described flat board goes to the bottom installed roller for combination roller, namely a centripetal inclined wheel 4 is all installed in the outside of each roller, still smooth and easyly can run when realizing escape tube distortion or the inclination of tractive flat board, ensure that escape car reliability of operation, improve the operational efficiency of escape car.Every pair roller is all packed on a fixed head 3, and this fixed head is fixed on flat board again and goes to the bottom.
The present embodiment gives the running status figure of flat car in escape tube 10.
