The carrier needs to slide a certain distance without power between the different driving mechanisms, and then the driving connection between the two driving mechanisms can be realized, which involves the driving cooperation problem between the downstream driving mechanism and the carrier. In addition, for the branch line convergence application on the water line, the carriers on the branch line converge to the main line, which also involves the driving cooperation problem between the driving device on the main line and the carrier just entering the main line.

[0003] The structure of the flexible driving mechanism generally includes a driving chain, and the driving chain can be pushed forward by arranging a plurality of bird hooks. The driving port is arranged on the bird hook, and the driving port is used for sleeving and cooperating with the hanging part on the carrier to drag the hanging part on the carrier to slide on the track. The bird hook is normally arranged in an inclined manner, and the downstream side of the bird hook is contacted with the hanging part on the carrier before the driving port. When the load of the carrier is light, the other parts of the bird hook except the part of the driving port can also push the hanging part of the carrier to slide on the track, which can cause poor stability of the carrier sliding on the main line track, the carrier is easy to stay on the main line track during the track change, and the carrier is easy to entangle with other carriers, thereby affecting the stability of the overall operation of the water line.

[0005] To solve the technical problem, the utility model discloses a technical scheme of a flow line into rail carrier drive device, which is arranged on the upside of a rail and comprises a flexible drive chain, the drive chain is connected to a chain wheel, and a plurality of driving members are arranged on the drive chain, the driving members are arranged at intervals on the drive chain, the driving member comprises a connecting piece fixed to the drive chain, the inner end of a bird hook is movably connected to the connecting piece, the outer end of the bird hook is a free end, a driving port is arranged on the downside of the outer end of the bird hook, and the spring acts on the bird hook to press the outer end of the bird hook to the rail, characterized in that a hooking waiting position is arranged at the inlet end of the rail, and the hooking part on the carrier receives the driving of the bird hook at the waiting position, a lifting piece is arranged on the upside of the waiting position, the lifting piece is used for abutting against the bird hook, the bird hook passes the lifting piece from the inlet end to the outlet end, the outlet end is overlapped with the orthographic projection of the waiting position, and after the bird hook is separated from the outlet end, the driving port is sleeved with the hooking part on the carrier at the waiting position.

[0006] The into rail carrier refers to the carrier on the main line entering the downstream side drive mechanism or the carrier on the branch line entering the main line. After the into rail carrier enters the rail of the main line, it is usually required to be stationary at the waiting position on the rail to receive the driving of the bird hook on the drive mechanism. Of course, the carrier can also be matched with the driving port on the bird hook during the travel. When the bird hook travels at the position of the lifting piece, the lifting piece lifts the outer end of the bird hook upward, and after the bird hook is completely separated from the lifting piece, the outer end of the bird hook moves downward to the position of the rail under the action of the spring. If the carrier is stationary at the waiting position, after the outer end of the bird hook falls, the driving port is sleeved with the hooking part on the carrier, and the stable dragging travel of the bird hook to the carrier can be realized.

[0007] Further, the lifting piece is a plate-shaped body, and the plate-shaped body is horizontally arranged. The lifting piece has a simple structure and good cooperation stability with the bird hook.

[0008] Further, the inlet end side of the lifting piece is provided with an inclined part, and the inclined part is low on the outside and high on the inside. The inclined part first contacts the bird hook, and the inclined part guides the bird hook to the upper surface of the lifting piece, so that the sliding smoothness of the bird hook on the lifting piece is good.

[0009] Further, the lifting piece is arranged close to the chain wheel, and the lifting piece is arranged on the tangential direction of the chain wheel. This well adapts to the travel direction of the bird hook, so that the driving port can be timely buckled with the hooking part on the carrier after the bird hook is moved to the position.

[0010] Further, the lifting piece is fixed to the upper end of a connecting frame, the connecting frame is curved, and the lower end of the connecting frame is fixed to the bottom surface of the rail through a connecting structure. This facilitates the connection and fixation of the lifting piece, and the connecting frame does not hinder the normal travel of the bird hook.

[0011] Further, two limiting sheets are arranged side by side at the middle position of the coupling piece, the bird hook is inserted between the two limiting sheets in a gap manner, and the spring is arranged between the two limiting sheets. On one hand, the cooperation stability between the bird hook and the coupling piece is improved, the relative position stability of the bird hook and the coupling piece is good, and the bird hook can well adapt to the arrangement of the lifting piece. On the other hand, the spring is convenient to arrange, and the action stability of the spring on the bird hook is good.

[0012] Compared with the prior art, the utility model has the beneficial effects that: the present into rail carrier driving device is used for driving the carrier just entering the rail to realize stable pushing of the carrier on the rail. The lifting piece is arranged on the upper side of the rail, in the process that the carrier transits to the target rail, the bird hook does not interfere with the unpowered forward movement of the carrier due to the block of the lifting piece, so that the carrier can smoothly enter the waiting position on the rail. Since the outlet end on the lifting piece and the waiting position have overlap in the orthographic projection, the hanging part of the carrier is hung on the rail at the waiting position, the driving port on the bird hook can be exactly sleeved on the hanging part of the carrier after the bird hook is separated from the lifting piece, the bird hook can stably drag the hanging part on the carrier to slide on the rail, and the carrier can accurately arrive at the specified target position.
