Description

A kind of anti-rope anti-noise protection device and method for overhead passenger mechanism

technical field

The invention relates to the field of coal mine safety, and more particularly to a device and method for preventing rope drop and noise protection of an overhead passenger mechanism.

Background technique

Overhead passenger devices are widely used underground in coal mines to transport people over long distances, and the safe operation of overhead passenger devices has always been an important issue in safety management. The working principle of the overhead passenger device is shown in Figure 1. Install the annular wire rope plugged at both ends on the driving device and the roundabout wheel, fix it with a supporting rope pulley, a pressure rope pulley, etc. in the middle, and tension it by a heavy hammer The device is tensioned. When the overhead passenger device is working, the motor of the driving device drives the reducer to rotate through the coupling, and the reducer drives the driving wheel to rotate, so that the wire rope wound between the driving wheel and the circuitous wheel can run in an infinite loop, or reciprocate up and down. Connect the sling chair with the rope holder, and then lock the rope holder on the running wire rope, and go up or down with the wire rope, so as to realize the purpose of conveying people. Due to the difference in the installation height, position and angle of the rope pulley, or the uneven force on the wire rope during operation and the precision of the surface of the rope pulley, etc., the wire rope will fall off at an uncertain position, causing the rope on the chair lift. The occupants suffered serious personal injury or death.

Chinese Patent Application No. CN201911077315.5 discloses a tensioning force adjustment device and a tensioning force adjustment method of an elevator wire rope testing machine. The existing elevator wire rope tension adjustment mechanism has the problems of insufficient tension and noise. The invention application includes an electric cylinder, a parallelogram mechanism, a pulley rod, a movable pulley, a linkage arm, a slider, an S-type tension sensor and a fixed pulley; when the wire rope is tested, the wire rope to be tested is passed around the loading wheel and the two fixed pulleys; One end of the wire rope is fixed with the S-type tension sensor, and the other end is fixed with the slider; the electric cylinder drives the linkage arm through the parallelogram mechanism, thereby driving the pulley rod and the movable pulley to move, and the wire rope to be tested is loosened or tensioned; the controller is based on the S-type tension sensor. The signal judges that when the tensile force of the wire rope to be tested reaches the test value, the motor that controls the electric cylinder stops. The electric cylinder of the invention application is stable in transmission, and the linkage arm is driven by a parallelogram mechanism, which can amplify the force of the electric cylinder and play an energy-saving role while ensuring the tension force. However, it is not suitable for the safety protection of the mine passenger device.

The fixing member 5 is fixed on the beam 4 . The beam 4 is the beam at the top of the coal mine roadway, which is used to fix the anti-dropping and anti-noise protection device. The fixing member 5 includes a bottom plate 501 and a vertical rod 502 , the bottom plate 501 is fixed on the bottom surface of the beam 4 by bolts, and the vertical rod 502 is fixed on the bottom plate 501 and is perpendicular to the bottom plate 501 and the beam 4 . The function of the fixing member 5 is mainly to fix and support the function of other components.

The connecting piece 6 is a long rod-shaped bolt with an external thread. One end of the connecting piece 6 is horizontally threaded through the fixing piece 5 and the end is locked by a nut. The connecting piece 6 is parallel to the ground. The other end of the connecting piece 6 is rotatably connected with the rotary card 7 .

The rotary clip 7 is in the shape of a cuboid with six end faces, one of which is recessed inward to form an arc-shaped groove, and the arc-shaped groove of the rotary clip 7 is facing the rope groove of the supporting rope wheel 8. The wire rope 3 It is located in the space enclosed by the arc groove and the rope groove of the rope pulley 8 . A protective baffle plate 9 is fixedly connected to the two end faces of the end face where the arc groove is located on the rotating clip 7 parallel to and perpendicular to the movement direction of the wire rope 3 . The ends of the two said protective baffles 9 that are close to the sheave 8 extend to the outer edge of the sheave 8 .
