Claims

. :. I the invention relates to the field of vehicles and relates to a mechanically independent, transporting elements of the charge (table (bik)) of refractory syringes of brick made by semi-dry pressing, as well as other areas of transport mechanics with address stop, nakfimer assembly conveyors in mechanical engineering. A carriage of an overhead pushing conveyor is known, comprising a pushing cam associated with a lever having a roller at one end interacting with the tire of the stop mechanism 1. The disadvantage of the present invention is unreliable operation, i.e. According to the first and second variants, an arbitrary disengagement of the carriage from the cart takes place; in the third variant, the locking device is complicated in design and also unreliable, and moreover, impossible. but disconnect the trolleys from the traction unit in case of a mechanical impediment to the movement of the trolley. :: A mechanism for the automatic coupling and disengagement of carts of a vertically closed conveyor with a pulling chain is known, which includes a housing and a hook with a pulling surface, pivotally connected to it, a pawl and a hoist. The disadvantages of this design is that the accumulation of carriages, dogs, installed in the cabs, will trigger the passage over the carriage, which entails additional wear of the conveyor parts, as well as when the dogs interact with each other and with other parts of the conveyor slip, which inevitably leads to increased wear of parts and, consequently, reduce the reliability of the conveyor in operation. The purpose of the present invention is to improve reliability in operation. The goal is achieved by the fact that the elevator is provided with a roller and the hook is made with a groove in which it is placed with the possibility of rolling the roller to the iodine syringe, with 9TU S1TYWHWH of the crH, the radius is bevel in the nisney his qaciTi, and the hook and doggy spring. The drawing shows schematically, j exaHH3M of automatic coupling and uncoupling of carriages to hull 1 and nOjaieMnik 2, hook 3 and pawl 4, with hook 3 and pawl 4 on the same axis. Hook 3 has a slit to position the pawl 4 and the roller 5 of the hoist 2, which is seated on, is rotated with a pneumatic pull. an axis fixed on the lift 2, and a tread surface S, extend a radius 6 with a bevel B in the lower part. Lamellar springs 6 and 7 are also attached to the housing 1, which abut their free ends on the hook 3 and dog 4. Automatic mechanical coupling and the release are bolted to the cart 8 ,, On the chain 9, with pitch depending on the length of the conveyor and the number of trucks, installed rollers 1O. The mechanism of automatic coupling and uncoupling works as follows: the hook 3 is engaged with the roller 10 of the pull chain 9. When the lift 2 stops in a standing BftepejitH cart or specially extended support, rtonbeNfHHK 2 starts turning around the axis, and the roller 5 of the lift 2 when This rolls into the groove of the hook 3, lifts it up. The ropik 10 of the chain, 9, rolling on the traction surface A and the bevel B, comes out of a sink with ball 3, and the telensk stops. In the case of a teleporter, the hook 3 is in a raised position (shown with a dash-dotted line in the drawing), and the rollers 10 of the continuously moving chain 9 are free; pass under it. As soon as the obstacle (upr, the cart standing in front, etc.) is removed, the main lift 2 and the hook 3 are freed, under the action of its own weight, the supper 3aMN {r сСШйШё® Roller 10 of chain 9 will lift the pawl 4, hook on the surface of hook 3 and the cart will move. After the passage of the roller 10 under the dog 4 of the last OP5s P1TS and thus eliminates the possibility of spontaneous rollback or lagging of the cart. In order that the hook 3 does not spontaneously get out of engagement with the roller 10 of the chain 9 on the curved sections of the conveyor, the traction surface of the hook 3 has a bevel B in the lower part. When the trolley moves in an inverted position, the hook 3 does not self-disengage the hook 3 with the chain roller 10, 9 if the chain 9 stops, the hook 3 and dog 4 are spring loaded with plate springs 6, 7. Dog 4 T (also serves to prevent hook 3 and self-roller 10 chain 9 when stopping the chain and when the trolley is moving on a curved section of the conveyor. The application of the mechanism according to the proposed application will ensure the reliability of the vertically closed and other carriage conveyors, allowing to exclude heavy manual labor during transportation Ke of refractory columns.
