The utility model has the advantages that: the utility model discloses an overhead people's car filter rope safety arrangement, because the lubricating oil and the environment in the pit of overhead people's car transportation rope in area send, easy adhesion debris during the operation, a small amount of debris can be filtered by "U" type mouth, owing to receive the frictional force of transportation rope to "U" type mouth when adhesion debris are too much, the filter rope spare can be along with the transportation rope is to the motion of transportation rope direction of motion, proximity switch senses the host computer outage of transporting control overhead people's car of filter rope spare this moment, avoid causing the transportation rope to get rid of the groove and then cause the personal safety accident.
Other advantageous effects of the present invention will be further described with reference to the following embodiments.
Drawings
The invention will be further described with reference to the following figures and examples:
FIG. 1 is a schematic side view of the present invention;
fig. 2 is a schematic axial view of another angle of fig. 1.
Detailed Description
As shown in the figure: the filter rope safety protection device for the overhead man-vehicle in the embodiment comprises a filter rope piece 6 matched with a transport rope 7 of the overhead man-vehicle and a proximity switch 8 used for sensing the movement of the filter rope piece 6 towards the motion direction of the transport rope; one end of the rope filtering piece 6 is provided with a U-shaped opening matched with the transportation rope 7, and the proximity switch 8 is used for controlling the power failure of a main machine of the overhead man car. The transport rope 7 is generally a steel wire rope, and the hollow arrow in the figure indicates the moving direction of the transport rope 7. Because the lubricating oil and the environment in pit that overhead man car haulage rope 7 was from the area result, easy adhesion debris during the operation, a small amount of debris can be filtered by "U" type mouth, owing to receive the frictional force of haulage rope to "U" type mouth when adhesion debris are too much, the straining rope spare can be along with the haulage rope towards the movement direction motion of haulage rope, proximity switch senses the host computer outage of the transport control overhead man car of straining rope spare this moment, avoids causing the haulage rope to take off the groove and then causes the personal safety accident.
In this embodiment, the proximity switch 8 is disposed on the switch bracket 9, the other end of the rope filter 6 is hinged to the switch bracket 9, and the other end of the rope filter 6 is the end without the U-shaped opening. Certainly also can set up the switch support into "L" type, let the other end and the switch support of straining the rope piece along the direction single degree of freedom sliding connection of transportation rope motion, also can realize the utility model discloses a purpose.
