Opened point, inductive head 4 can sense that the maximum distance of tablet 5 is 2cm, when tablet 5 is more than at a distance from inductive head 4
After 2cm, inductive head 4 incudes the inductive signal less than tablet 5, and the switching point of inductive head 4 disconnects, and then makes truck electrical control
The power supply of system shutdown truck 7 keeps truck 7 out of service, avoids the accident to slide down after 7 pulleying of truck and occurs.
Further, pedestal 3 is formed by connecting by transverse slat and riser, and the bottom end of riser is connect with platform 1, the top of riser with
One end of transverse slat connects, and inductive head 4 passes through transverse slat, the upper end of inductive head 4 to be located at the top of transverse slat, and the lower end of inductive head 4 is located at
Between transverse slat and platform 1.Such setting makes inductive head 4 be more firmly mounted, and operation is more stablized.
Further, when the upper surface of stop tab 12 and platform 1 contacts, the limit position of the other end of connecting rod 6 than truck 7
It sets (when master controller is normal, the position on the most vertex that truck 7 can rise is extreme position) and is less than 20cm.When truck mistake
When volume, the distance that truck rises less than 20cm can touch cross-arm, and then inductive head 4 is made to lose induction, and control truck stops
It only runs, prevents 7 pulleying of truck and slide down.
It can be seen from the above description that the above embodiments of the present invention realize following technique effect：
A kind of protective device of truck pulleying, including truck 7, platform 1, traction rope 2, pedestal 3, inductive head 4, tablet 5,
Connecting rod 6 and touch cross-arm 13, pedestal 3 is fixedly installed on platform 1, and inductive head 4 is vertically arranged on pedestal 3, inductive head 4 it is defeated
Go out circuit to be electrically connected with truck electric control system, tablet 5 can be close to or far away from inductive head 4, one end of connecting rod 6 and sense
Plate 5 is answered to connect, the other end of connecting rod 6 can contact or separate with truck 7.
Master controller in truck electric control system is normal, when truck 7 rises to extreme position, traction
Bar is not contacted with cross-arm 13 is touched, and inductive head 4 can sense that tablet 5,4 switching point of inductive head are connected, truck electrical control
System can stop according to relying on master controller to control truck 7 under normal circumstances.
In the master controller failure of truck electric control system, truck draw bar 8 oversteps the extreme limit and touches behind position
Cross-arm 13 is touched, truck 7 continues up operation, touches cross-arm 13 and connecting rod 6 and tablet 5 is pushed to move up, inductive head 4 is felt
It should be disconnected less than the inductive signal of tablet 5,4 switching point of inductive head, and then truck electric control system is made to cut off truck power supply,
Keep truck 7 out of service, avoids the accident to slide down after 7 pulleying of truck, ensure being smoothed out for blast fumance.
