A. 26 stretches out right riser 1 and revolves on 47; Second oil cylinder 42 is connected the lateral surface of bottom right frame 14, and swings 44 through second piston rod 43 and second and be connected.
Principle of work in the face of apparatus of the present invention describes in detail down.
Shown in Figure 3 is under the load-transfer device normal operating condition, the state of each member in this device.Load-transfer device with speed V when direction as shown is moved; Last turning rack assembly 4 has the trend of downward upset under the effect of self gravitation and torsion spring 33 tension force; This trend makes down turning rack assembly 7 that resupinate trend arranged through last link gear and torsion spring 33; Thereby upper supporting roller 6 on the turning rack assembly 7 being close to carry is with 34 lower surfaces; Upper supporting roller 6 has played supporting role and has been with 34 to rotate with carrying, but owing to carry the existence with 34 internal tensions, has stoped the movement tendency of time turning rack assembly 7 and has reached the balance of upper and lower turning rack assembly 4,7.Equally, the snub pulley 22 of backhaul band turning rack assembly 10 is pressed on backhaul band 35 upper surfaces and rolls with backhaul band 35.
As shown in Figure 5, when load-transfer device normally moved, under the stopping of push rod 20, following invertible head crank 21 can't be swung to the right, thereby had stoped the downward upset of backhaul band turning rack assembly 10.
Shown in Figure 4 is under load-transfer device generation broken belt situation, the state of each member in this device.When 34 broken belts are with in carrying; Tension force in the load-transfer device loses or die-offs; Last turning rack assembly 4 by gravitys overturn downwards; And making down turning rack assembly 7 produce upwards overturning couple through interlock connecting rod 17, this moment overcomes load-transfer device, cargo and the gravity of turning rack assembly 7 self down, turning rack assembly 7 is made progress overturn.When being turned to certain angle, first, second friction shoe 28,30 clampings of upper and lower turning rack assembly 4,7 are carried and are with 34.Because first, second friction shoe 28,30 and the existence of carrying, carry and be with 34 and 28,30 formation of first, second friction shoe self-locking, thereby be with carrying 34 firmly to arrest with 34 upper and lower inter-surface friction power.Following turning rack assembly 7 upwards upset can will carry to be with on 34 broken belts and turns over, and lays down the cargo that carries with on 34, carries out along the entire belt cross direction and arrests, and belt body is damaged little, arrests the reliability height.The interlock of upper and lower two turning rack assemblies 4,7 is simultaneously used, and can effectively reduce the lift height that carries with 34, and upper and lower two turning rack assemblies, 4,7 required overturning couple are reduced.
As shown in Figure 6; When turning rack assembly 7 upwards overturn instantly, lower crank 18 was swung to the right through short connecting rod 19 pulling push rods 20, thereby invertible head crank 21 is swung to the right under allowing; Promptly realize counter-clockwise swing, thereby make backhaul band turning rack assembly 10 rely on the effect of gravity to overturn downwards.At this moment; Because backhaul band 35 also loses tension force, can't overcome the gravity of backhaul band turning rack assembly 10, therefore; Backhaul band 35 is pressed onto on the crossbeam 11 by backhaul band turning rack assembly 10; Same because the 3rd friction shoe 23 exists with crossbeam 11 and backhaul band 35 upper and lower inter-surface friction power, and backhaul band 35 forms self-locking with the 3rd friction shoe 23,11 on crossbeam, thus the arresting of completion backhaul band 35 broken belts.This shows; Because the present invention adopts the linkage from top to bottom device; Therefore, when carrying adhesive tape arresting agency was failure to actuate, then backhaul adhesive tape arresting agency just can not work; Thereby produce misoperation when effectively having prevented backhaul band 35 accidental relaxing, promptly guaranteed to arrest device and do not received the fluctuation of backhaul band 35 sags to cause misoperation.
Like Fig. 7, shown in Figure 8; On arrest regulating mechanism 15 and do the time spent, first piston bar 41 stretches out, and makes first swing, 46 a upwards swing; Drive second and revolve 45 and rotate to an angle, make first, second friction shoe 28,30 of upper and lower turning rack assembly 4,7 break away from locking states.Equally, arrest second piston rod, 43 collapsing lengths of regulating mechanism 13 under the adjustment, make second swing, 44 a drive third axle revolve 47 rotation, the release after realizing the position adjustments of backhaul band turning rack assembly 10 and arresting braking.When arresting device Installation and Debugging, load-transfer device maintenance or repairing; Can be through first, second oil cylinder 40,42 oil cylinders of adjustment; Make first swing 46 and second swing 44 drive respectively second revolve 45 and third axle revolve a rotation of 47, thereby adjust each turning rack assembly clamping load-transfer device at arbitrary height or return and be fixed on the initial position.
In sum, carrying adhesive tape arresting agency among the present invention and backhaul adhesive tape arresting agency can be arrested and lock load-transfer device is large-area, and new tearing takes place when avoiding arresting broken belt; In addition, the present invention has increased lock torque simultaneously through the linkage from top to bottom device is set, and has avoided occurring misoperation, and, regulate release mechanism through increasing, made things convenient for this Unit Installation, debugging and maintenance.
