Problems solved by technology
[0003] The disadvantage of this type of offside protection device is that this induction device is easily affected by various external factors. Because it is electromagnetic induction, bolts and other magnetic steel materials that are close to it can affect it; The sagging and so on can cause it to issue wrong instructions, causing frequent shutdowns of the equipment and affecting the normal operation of the equipment.
Therefore, the induction device needs to be adjusted frequently, which increases the workload of unnecessary equipment maintenance.

Embodiment
[0013] Such as figure 1 The offside protection device for an overhead passenger device of a mobile grip shown in the figure includes an offside switch 1 connected to the PLC main control system, an offside switch touch bar 5 connected to the bottom of the offside switch 1, an offside switch 1 and an offside switch mounting plate 2 Connected, the offside switch mounting plate 2 is connected with the U-shaped bolt 4 through the angle steel 3, the offside switch 1 is a travel switch, and the offside switch 1 and the offside switch mounting plate 2 are connected by bolts.
[0014] The use state of an offside protection device for an overhead passenger device of a movable grip is as follows: figure 2 As shown, the rope-supporting wheel 7 is fixed on the I-shaped steel beam 6, and the offside protection device is installed on the I-shaped steel beam 6, which is located on one side of the rope-supporting wheel 7. Cable device 9 is connected with hanging chair. When the overhead pa...

The invention relates to the field of coal conveying machines, in particular to an offside protective device for a movable rope clip overhead man-riding device. The offside protective device comprises an offside switch connected with a PLC master control system, the lower portion of the offside switch is connected with an offside switch touching rod, the offside switch is connected with an offside switch installing plate, the offside switch installing plate is connected with a U-type bolt through angle steel (3), and the offside switch is a travel switch and connected with the offside switch installing plate through bolts. By the adoption of a travel switch mode, the phenomenon of abnormal shutdown caused by false operation on the switch by other components is avoided, equipment and staff security is ensured, the unnecessary equipment maintenance workload is reduced, and the offside protective device is simple in structure, low in cost and convenient to maintain.
Description
technical field [0001] The invention relates to the field of coal conveying machinery, in particular to an offside protection device for an overhead passenger device of a movable grip. Background technique [0002] The safety of the overhead passenger device is the key to underground operations. The existing offside protection device for the overhead passenger device of the grip rope device adopts the proximity switch form of photoelectric induction, and its principle is: to control the distance between the steel wire rope and the induction device. Inside, the sensing device has no signal output, and the overhead passenger device continues to operate; when the passenger is offside, due to the increase in the mass of the person and the hanging chair, the steel wire rope sags, and the distance between the steel wire rope and the sensing device changes. At this time, the sensing device Sensing this change, it immediately sends an offside command to the PLC main control system,...
