Abstract
The invention provides a barrier-free rope-falling prevention device. The barrier-free rope-falling prevention device comprises a fixed support and a supporting plate, wherein the upper end of the fixed support is fixed to a cross beam; the cross section of the supporting plate is in a V shape, and the included angle between the two inclined sides of the supporting plate is an acute angle; one inclined side of the supporting plate is fixed to the fixed support, an opening of the supporting plate faces the position above the opening, and the inner side faces of the two inclined sides of the supporting plate are provided with a circular arc surface I and a circular arc surface II in the length direction respectively. The supporting plate is located below a pulling rope after being mounted; when the pulling rope falls off, the pulling rope falls into the supporting plate through the opening of the supporting plate since the supporting plate is in the V shape. Because the inner side faces of the two inclined sides of the supporting plate are provided with the circular arc surface I and the circular arc surface II in the length direction respectively, on the condition that the pulling rope does not stop moving, a rope gripper and a hanging chair can move across the circular arc surface I and the circular arc surface II. The situation that when the pulling rope falls off, an aerial passenger device does not stop for some reasons, the pulling rope still runs to drive the rope gripper and the hanging chair to collide with the rope-falling prevention device, and then people are injured is effectively prevented.
Description
Technical field
The present invention relates to technical field of coal mine equipment is and in particular to without hindrance anti-lost on a kind of Aerial Conveyance for Human in Coal Mine
Rope device.
Background technology
Adopting hook the anti-rope falling device supporting plate using on domestic Aerial Conveyance for Human in Coal Mine, it is mainly flat by one piece more
It is hook-shaped that plate strikes out similar semicircle, is arranged in torr rope sheave side-lower more, automatically controlled protection system lost efficacy or protection act not in time,
Overhead manned equipment does not stop in time when falling and restricting, and rope-grippers and chair lift will be led to clash into old-fashioned anti-rope falling device and (or claim to catch rope
Device) on hook-shaped supporting plate, thus leading to chair lift and personnel to overturn and get rid of winged accident.Even if automatically controlled protection do not lost efficacy it is also possible to
Fall that when restricting, just rope-grippers and chair lift are fallen on the hook-shaped supporting plate of anti-rope falling device thus producing obstruction to overturn accident.
Content of the invention
The present invention is in order to overcome the shortcomings of above technology, there is provided one kind can hook traction when pull rope falls and restricts, and
Rope-grippers and the without hindrance anti-rope falling device of chair lift motion will not be hindered.
The present invention overcomes its technical problem be the technical scheme is that
This without hindrance anti-rope falling device, comprising:
Fixed mount, its upper end is fixed on crossbeam；
Supporting plate, its cross section is in " v " font, and the angle between two hypotenuse is acute angle；
One hypotenuse of described supporting plate is fixed on fixed mount, the opening of described supporting plate towards oblique upper, the two of described supporting plate
Cambered surface and the cambered surface of circular arc are respectively arranged with along its length on the medial surface of individual hypotenuse.
In order to realize, upper-lower height is adjustable, also includes some installing holes of being arranged at from top to bottom on fixed mount and sets
It is placed in the installing hole on supporting plate, fixed using nut after screw bolt passes installing hole and installing hole.
The invention has the beneficial effects as follows: supporting plate is located at below pull rope after installing, when pull rope falls and restricts, due to supporting plate
In v font, pull rope falls in supporting plate at the opening of supporting plate.Due on the medial surface of two hypotenuses of supporting plate along its length
It is respectively arranged with cambered surface and the cambered surface of circular arc.Therefore in the case of pull rope not stop motion, rope-grippers and chair lift can
With through cambered surface and cambered surface motion.Effectively prevent when pull rope falls and restricts, overhead manned equipment does not stop for some reason
Car, pull rope is still running, thus driving rope-grippers and chair lift to clash into anti-rope falling device and produce casualty accident.

Specific embodiment
Below in conjunction with the accompanying drawings 1, the present invention will be further described for accompanying drawing 2.
This without hindrance anti-rope falling device, comprising: fixed mount 1, its upper end is fixed on crossbeam；Supporting plate 5, its cross section is in
" v " font, the angle between two hypotenuse is acute angle；One hypotenuse of supporting plate 5 is fixed on fixed mount 1, the opening court of supporting plate 5
Obliquely upward, the medial surface of two hypotenuses of supporting plate 5 is respectively arranged with along its length cambered surface 6 and the cambered surface of circular arc
7.Supporting plate 5 is located at below pull rope after installing, and when pull rope falls and restricts, because supporting plate 5 is in v font, pull rope is from supporting plate 5
Fall at opening in supporting plate 5.Due to the arc of circular arc being respectively arranged with along its length on the medial surface of two hypotenuses of supporting plate 5
Face 6 and cambered surface 7.Therefore in the case of pull rope not stop motion, rope-grippers and chair lift can be through cambered surface 6 and arcs
Move in face 7.Effectively prevent when pull rope falls and restricts, overhead manned equipment does not stop for some reason, and pull rope still exists
Run, thus driving rope-grippers and chair lift to clash into anti-rope falling device and produce casualty accident.
Some installing holes 2 of being arranged at from top to bottom on fixed mount 1 can also be included and be arranged at the peace on supporting plate 5
Dress hole 8, supporting plate 5 can adjust suitable position along fixed mount about 1, after being adjusted in place, bolt 3 is sequentially passed through peace
Fixing using nut 4 behind dress hole 8 and installing hole 2.It is achieved that the adjustable purpose of upper-lower height, can be according to difference
Working environment convenient adjust.
