A. 26 and stretches out the 3rd of right riser 1 and revolve on 47; Second oil cylinder 42 is connected the lateral surface of bottom right frame 14, and swings 44 by second piston rod 43 and second and be connected.
Principle of work to apparatus of the present invention describes in detail below.
Figure 3 shows that under the load-transfer device normal operating condition state of each member in this device.When load-transfer device moves along direction as shown with speed V, 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 be arranged by last link gear and torsion spring 33, thereby make down upper supporting roller 6 on the turning rack assembly 7 be close to carrying and be with 34 lower surfaces, upper supporting roller 6 has played supporting role and has been with 34 to rotate with carrying, but because carrying with the existence of 34 internal tensions, has stoped the movement tendency of time turning rack assembly 7 and has reached upper and lower turning rack assembly 4,7 balance.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.
Figure 4 shows that 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 is upset downwards under the gravity effect, and make down turning rack assembly 7 produce the overturning couple that makes progress by interlock connecting rod 17, this moment overcomes load-transfer device, cargo and the gravity of turning rack assembly 7 self down, and turning rack assembly 7 is upwards overturn.When being turned to certain angle, upper and lower turning rack assembly 4, first, second friction shoe 28 of 7,30 clampings carrying are with 34.Because first, second friction shoe 28,30 with carrying with the existence of 34 upper and lower inter-surface friction power, carrying is with 34 and first, second friction shoe 28,30 formation self-lockings, thereby is with carrying 34 firmly to arrest.Following turning rack assembly 7 upwards upset can be with carrying on 34 broken belts and turn over, and lays down carrying with the cargo on 34, carries out along the entire belt cross direction and arrests, and is little to the belt body damage, arrests the reliability height.Upper and lower two turning rack assemblies 4,7 interlock simultaneously used, and can effectively reduce carrying with 34 lift height, 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 by short connecting rod 19 pulling push rods 20, thereby invertible head crank 21 is swung to the right under allowing, namely 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 and crossbeam 11 exist with backhaul band 35 upper and lower inter-surface friction power, backhaul band 35 and the 3rd friction shoe 23,11 on crossbeam form self-locking, thereby finish arresting of 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 is 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, namely guaranteed to arrest device and be not subjected to the fluctuation of backhaul band 35 sags to cause misoperation.
As 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 upper and lower turning rack assembly 4, first, second friction shoe 28,30 of 7 break away from locking states.Equally, adjust second piston rod, 43 collapsing lengths of arresting regulating mechanism 13 down, make second swing, 44 the 3rd of a drive 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 by adjusting first, second oil cylinder 40,42 oil cylinders, make first swing 46 and second swing 44 drive second respectively and revolve 45 and the 3rd and 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, the 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 by the linkage from top to bottom device is set, and has avoided occurring misoperation, and, regulate release mechanism by increasing, made things convenient for this Unit Installation, debugging and maintenance.
Above-described, be preferred embodiment of the present invention only, be not in order to limiting scope of the present invention, the above embodiment of the present invention can also make a variety of changes.Be that simple, the equivalence that every claims according to the present patent application and description are done changes and modification, all fall into the claim protection domain of patent of the present invention.The present invention not detailed description be the routine techniques content.
