Embodiment

[0054] When the operator stops working, after the hydraulic system platform is reset, the platform reset normally open contact SB5 is closed, the relay K2 is energized, the SB6 normally closed contact is disconnected, the platform off-position relay KJ7 is de-energized, and the positioning pin sensor switch 4 is activated. Electricity.

[0055] At this time, if the operator does not put the positioning pin 3 into the positioning pin mounting seat 2, the positioning pin sensor switch 4 outputs a low level, the positioning pin relay K1 is out of power, and the first positioning pin alarm normally closed contact K1.2 is closed At the same time, the platform off-position relay KJ7 loses power, the second positioning pin alarm normally closed contact KJ7.3 is closed, and the positioning pin indicator EL1 is on. Remind the operator that the positioning pin 3 has not been put into the positioning pin mounting seat 2, please put the positioning pin 3 into its positioning pin mounting ...

Abstract

The invention provides an anti-misoperation protective device for a position-fixing pin of a platform of a catenary operation car. The anti-misoperation protective device comprises a power supply, a position-fixing pin inductive switch, a position-fixing pin relay, a hydraulic system normally closed contact and a hydraulic system electrical circuit, wherein the power supply end of the power supplyis connected with the power input end of the position-fixing pin inductive switch; the output end of the position-fixing pin inductive switch is connected with the input end of the position-fixing pin relay; the output end of the position-fixing pin relay is connected with the input end of the hydraulic system normally closed contact; the output end of the hydraulic system normally closed contactis connected with the input end of the hydraulic system electrical circuit; the position-fixing pin inductive switch is fixed on a position-fixing pin mounting seat; and the position-fixing pin inductive switch is connected with the hydraulic system electrical circuit by the position-fixing pin relay. When the position-fixing pin inductive switch senses the position-fixing pin, a high electricallevel is outputted so as to cut off the hydraulic system electrical circuit and the platform can not work; and when the position-fixing pin inductive switch does not sense the position-fixing pin, a low electrical level is outputted so as to close a hydraulic system electrical circuit and the platform can work normally.

Description

technical field [0001] The invention relates to the field of catenary operation vehicles, in particular to an anti-misoperation protection device for positioning pins of a catenary operation vehicle platform. Background technique [0002] When the operator uses the operation platform of the catenary operation vehicle, the function of the positioning pin of the catenary operation vehicle is: after the operation is completed, the operator resets the platform and places the positioning pin in its mounting seat, that is, the positioning pin returns to its original position. , the operation is over, and the platform will not be able to operate. And in actual work, the operator is eager to work, or the detection work is not in place, and the positioning pin is still in the mounting seat and starts to operate the platform, causing the phenomenon that the positioning pin zipper is broken. [0003] Therefore, it is necessary to provide a positioning pin anti-misoperation protection ...
