Background
Monorail crane transportation is the best transportation equipment with high efficiency and safety in the current coal mine underground auxiliary transportation, a monorail crane is a transportation locomotive running on a suspended special monorail, all monorail cranes run on one rail, and therefore collision possibility exists between the monorail crane and the monorail. The track fork needs to have the switch that can change track circuit direction, and the single track hangs the passageway switch or walks to the track end and have the possibility of falling the way, has the potential safety hazard.
Disclosure of Invention
The invention aims to solve the technical problem of providing a monorail crane trolley which can prevent the monorail crane trolley from colliding with a guide rail and falling off the rail.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: an anti-collision and anti-lane-dropping monorail crane trolley comprises a connecting rod, a trolley frame, traveling wheels, a collision plate, a travel switch and a pull rod;
one end of the connecting rod is connected to a traction spare connecting seat of the monorail crane, the other end of the connecting rod is connected with one end of the trolley frame through a pin shaft, the trolley frame is connected with the track through a traveling wheel at the top, a collision plate is movably mounted in the middle of the other end of the trolley frame, a transverse plate is arranged in the middle of the trolley frame, and a travel switch capable of being in contact with the back of the collision plate after swinging is arranged at the bottom of the transverse plate;
one end of the connecting rod connected with the trolley frame is also connected with one end of a pull rod, and the other end of the pull rod is connected with the bottom of the collision plate.
The connecting rod comprises a rod body, a pair of L-shaped connecting lugs and a ball sleeve type connector, wherein the L-shaped connecting lugs and the ball sleeve type connector are symmetrically arranged;
a pair of L type engaging lug and ball cover formula connector are established respectively at the both ends of the body of rod, and wherein, ball cover formula connector is connected with the reserve connecting seat of pulling that the single track hung, and the one end and the body of rod of L type engaging lug are connected, and the other end and the one end of pull rod of L type engaging lug are connected to the one end of being connected at L type engaging lug and the body of rod still articulates the one end that has the trolley frame.
One end of the pull rod connected with the connecting rod is a threaded end, and an adjusting nut for adjusting the sensitivity of the travel switch is further arranged at the threaded end.
Compared with the prior art, the invention has the following beneficial effects.
According to the invention, the travel switch is arranged in the middle of the trolley frame, the collision plate capable of contacting the travel switch after swinging is arranged at the end part of the trolley frame in the traveling direction, when the trolley frame collides or falls off the track in the running process of the monorail crane, the trolley frame can rotate downwards around the pin shaft connected with the connecting rod, at the moment, the pull rod can pull the collision plate to swing and trigger the travel switch, and the travel switch sends a stop signal to the system to stop the trolley frame from traveling. The trolley has a simple structure, is convenient to operate, and effectively improves the safety of the trolley in the rail walking.
The adjusting nut is arranged at the end part of the pull rod, and the relative distance between the other end of the pull rod and the collision plate is changed along with the screwing-in and screwing-out of the adjusting nut, so that the sensitivity of the travel switch is changed.
