Device 9 processed is friction type torque limiter 9, and locking pin shaft 5 card resistance occurs in sleeve 4 and can not translate in 7 course of work of motor
When, the torque that screw rod 6 is subject to increases rapidly, and 9 inner attrition piece of torque limiter skids when torque increases to preset value, cuts off motor
Power transmission between 7 and screw rod 6, screw rod 6 stop operating, and protect screw rod 6 and nut 11；The nut 11 being screwed on screw rod 6
It is linked together by bolt and the locking pin shaft 5, locking pin shaft 5 is moved along 6 length direction of screw rod, and right end extends outward
Sleeve 4 is simultaneously threaded through in the lock hole 12 of the gate 1；It is provided on the side wall of the workbench 2 for detecting the lock
First proximity sensor 14 of 1 first metal inductor 13 of door；4 upper side wall of sleeve offers to be extended along its length
Strip-shaped hole 15, the second metal inductor 16 for being vertically connected in locking 5 left end of pin shaft extend upward the strip-shaped hole 15,
The T-shaped structure of second metal inductor 16 is respectively arranged with second close to biography on the sleeve 4 of 15 arranged on left and right sides of strip-shaped hole
Sensor 17 and third proximity sensor 18；First proximity sensor 14, the second proximity sensor 17, third proximity sensor
18 signal output end is electrically connected with the signal input part of controller, the control output end of the controller and the motor 7
Control signal electrical connection.Wherein, the first metal inductor 13 on gate 1 rises with gate 1 and is risen, when the first close biography
It indicates that gate 1 rises in place when sensor 14 is overlapped with the first metal inductor 13, guarantees the axis of locking pin shaft 5 and lock hole 12
It is overlapped, convenient for interspersed locking；Second proximity sensor 17 be used for control locking pin shaft 5 retraction extreme position, when second approach
Pin shaft 5 is locked when sensor 17 is overlapped with the second metal inductor 16 and is retracted to extreme position, and the second proximity sensor 17 is to control
Device processed issues the signal of locking pin shaft 5 retraction in place, prevents locking 5 inner end dieback sleeve 4 of pin shaft and damages motor 7；Third
Proximity sensor 18 is used to control the stretching limiting length of locking pin shaft 5, shows when the second metal inductor 16 is overlapped with it
Locking pin shaft 5 reaches maximum extension elongation, and third proximity sensor 18 issues the signal for extending out to extreme position, control to controller
Device control motor 7 processed stops working, and prevents nut 11 from deviating from from screw rod 6, it is ensured that locked secure.
As shown in Fig. 2, 4 right end of sleeve is provided with end cap 19, it is provided on the through-hole of the end cap 19 and the locking pin
Axis 5 is slidingly sealed the sealing ring 20 of cooperation, prevents locking pin shaft 5 from shaking, it is ensured that its operational safety is stablized；Positioned at the strip-shaped hole
4 inner surface of sleeve on 15 right sides is horizontally disposed sliding bearing 21, and the locking sliding of pin shaft 5 is threaded through in sliding bearing 21, reduces
The frictional force between pin shaft 5 and sleeve 4 is locked, and then locking 5 outer surface of pin shaft is avoided to wear, further increases locking pin
The safety of axis 5.
The course of work and principle of the utility model are summarized as follows:
For the long-range control for realizing gate 1, the control signal of headstock gear is electrically connected with the control output end of controller, is grasped
It is interior when making to be provided with " gate raising " button and " gate decline " button, so that gate can be realized in operator in operating room
The long-range control of 1 lifting.
1 lock out action process of gate is as follows: controller is issued to headstock gear after operator presses " gate raising " button
Instruction, headstock gear drive gate 1 at the uniform velocity to rise, by taking the lock cell in 1 left side of gate as an example: the first metal sense when gate 1 rises
It answers body 13 with its rising, indicates that gate 1 rises in place when the first metal inductor 13 is overlapped with the first proximity sensor 14, tool
Body is as shown in Figure 1；First proximity sensor 14 issues the signal of the rising of gate 1 in place to controller, and controller is sent out to headstock gear
Halt instruction out, gate 1 stop rising；Then controller issues " locking " instruction to motor 7, and motor 7 passes through retarder 8, torsion
Square limiter 9 drives 6 low speed of screw rod to rotate forward, and the nut 11 on screw rod 6 drives locking pin shaft 5 to move right, when the second metal sense
Pin shaft 5 is locked when body 16 being answered to be overlapped with third proximity sensor 18 and extend out to extreme position to the right, and locking 5 right part of pin shaft is complete
It is interspersed in lock hole 12；Third proximity sensor 18 passes to controller, controller for the signal that pin shaft 5 stretches out in place is locked
The instruction that stops working is issued to motor 7, locks pin shaft 5 and 12 clearance fit of lock hole at this time and not load-bearing, it is specific such as Fig. 3
It is shown；Then controller issues the action command of " crawl decline " to headstock gear, after headstock gear drives gate to drop to 1~2 second
Autostop, so that gate 1 is edged down ensures to lock pin shaft 5 and locking upper disc of perforating completely attaches to, so by the weight of gate 1 by
Headstock gear is transferred to completely on locking pin shaft 5, realizes the automatic locking of gate 1, specific as shown in Figure 4.
1 unlocking motion process of gate is as follows: the closing of operator's long-range regulating gate 1 in operating room, when gate 1 needs
When wanting automatic unlocking and decline, operator presses " gate decline " button, and controller issues " crawl to headstock gear first
The instruction of rising ", autostop after headstock gear drives gate 1 to rise 1~2 second, 1 microlitre of gate makes to lock pin shaft 5 and lock hole
The weight of gate 1 is transferred on headstock gear by 12 clearance fits completely by locking pin shaft 5, specific as shown in Figure 3；Then it controls
Device issues " unlock " instruction to lock cell again, and motor 7 drives 6 low speed and reverse of screw rod, spiral shell by retarder 8, torque limiter 9
Mother 11 drives locking pin shaft 5 to be retracted along sleeve 4 and moves, when the second proximity sensor 17 is overlapped with the second metal inductor 16
When, locking pin shaft 5 is retracted to extreme position, and right end completely disengages lock hole 12, shown in specific Fig. 1, second approaches biography at this time
Sensor 17 issues retraction signal in place to controller, and controller issues halt instruction to motor 7, and lock cell stops working；So
Controller issues action command to headstock gear afterwards, and headstock gear operate and gate is driven to decline, complete gate 1 automatic unlocking and oneself
Dynamic decline.
