Detection switch one 3-1 and detection switch two 3-2 are both travel switches, when the crane arm is in place, the crane arm contacts detection switch one 3-1, detection switch one 3-1 acts, when the crane arm is in place, the protrusion on the outer wall of the rotating disc of the crane contacts detection switch two 3-2 to make detection switch 3-2 act, after the crane arm falls into place, detection switch one 3-1 can sense the crane arm, and normally closed contact one 14-1 changes from normally closed to normally open. Detection switch two 3-2 is installed at the crane rotating mechanical locking device through another mounting seat 12-2, the installation position of the arm falling in place travel switch is shown in Figure 2, and the installation position of the crane rotating locking in place travel switch is shown in Figure 3. Figure 1 When the crane is completely rotated in place, detection switch two 3-2 senses the rotating locking device, normally closed contact two 14-2 changes from normally closed to normally open, the installation position of the crane rotating locking in place travel switch is shown in Figure 3. Figure 2The normally closed contacts of the two detection switches, 14-1 and 14-2, are connected in parallel in the circuit. Only when the crane is fully retracted, the two detection switches sense the crane retraction signal, and both normally closed contacts are disconnected, the relay coil 5-1 loses power, as shown in the attached Figure 4 The relay normally closed contact 5-2 connected in series in the heavy railcar running circuit remains closed, and the heavy railcar running control circuit can work normally, allowing the powered heavy railcar 1 to run normally. When the crane is working, if any of the detection switches detects that the boom is not in place, the normally closed contact of the detection switch does not act, the relay coil 5-1 is powered, the relay normally closed contact 5-2 is actuated to open, and the heavy railcar running control circuit cannot be turned on, and the heavy railcar running control circuit cannot be controlled normally.
