In the travel direction of the front vehicle, the distance between the position where the stopper arm b3 is in the extended state suitable for stopping the rear vehicle (i.e. the position abutting on the leg of the rear vehicle) and the position where the unhooking handle b201 of the front vehicle is forced to rotate and disengage from the rear vehicle by the unhooking plate b2 is smaller than the distance between the unhooking handle b201 of the front vehicle and the position where the rear vehicle contacts the stopper arm b3 (i.e. the position of the leg of the rear vehicle) under normal conditions.

As shown in fig. 6, a detection system is further disposed on the fixed platform b1, the detection system includes a controller (not shown in the figure) and at least one detection switch b8, the controller is electrically connected to any one detection switch b8 and the second driver to receive a position signal of the skip detected by the detection switch b8 and an action signal fed back by the second driver, so as to start or stop the unhooking and blocking actions, in this embodiment, the detection switch b8 is a photoelectric detection switch, the detection switches b8 are two, in the running direction of the skip, the two detection switches b8 are disposed behind the unhooking plate b2 and behind the blocking arm b3, respectively, and the distance between the two detection switches b8 is greater than the distance between the adjacent front car and the adjacent rear car.

When the detection switch b8 behind the blocking arm b3 is used as a first detection switch b8, the detection switch b8 behind the unhooking plate b2 is used as a second detection switch b8, when the front vehicle moves along the running direction and enters a detection range, the first detection switch b8 firstly detects the front vehicle, the front vehicle moves forwards, the second detection switch b8 simultaneously detects the front vehicle, the front vehicle continues to move, when the front vehicle leaves the detection range of the first detection switch b8, the first detection switch b8 feeds back a signal to the controller, the controller starts the fourth push rod cylinder b4, the fourth push rod cylinder b4 contracts to drive the unhooking plate b2 and the blocking arm b3 to synchronously run, synchronous unhooking and blocking actions are carried out, when the rear vehicle enters the detection range of the first detection switch b8, the blocking arm b3 abuts against the rear vehicle to finish the blocking action, the unhooking plate b2 finishes the unhooking action simultaneously, and the front vehicle continues to move forwards and leaves the detection range of the second detection switch b8, at this time, the second detection switch b8 feeds back a detection signal indicating that the unhooking blocking action is completed and the unhooking is successful. If the position signal of the front vehicle is continuously detected by the second detection switch b8 after the unhooking blocking action is finished, or the rear vehicle continuously advances to force the blocking arm b3 to move reversely and force the push rod of the fourth push rod cylinder b4 to be pushed out passively, so that the signal of the fourth push rod cylinder b4 is lost, indicating that the unhooking is failed, and sending an alarm after the controller receives the signals of the second detection switch b8 and the fourth push rod cylinder b4, so that the emergency stop of the skip is started, and the skip and the unhooking blocking mechanism are prevented from being damaged by continuous advancing.

As shown in fig. 5, a pneumatic triple b90 is further disposed on the fixing plate 'b 11 between the base b10 and the fixing platform b1 to provide a stable air source for the fourth push rod cylinder b4, and a solenoid valve assembly b91 is also disposed on the other side of the fixing plate' b11, as shown in fig. 6, an electrical junction box b92 is mounted on the other side of the fixing plate 'b 11 to integrate electrical and pneumatic components on the fixing plate' b11, so that the structure is compact and convenient for wiring, and the overall structure is more attractive.

The working process of the unhooking blocking mechanism in the embodiment is as follows:

taking fig. 5 as an example, the push rod of the fourth push rod cylinder b4 is pushed out, and the stop arm b3 is in the initial state in the plane of the fixed platform b 1.

When the front vehicle carrying materials is hooked with the rear vehicle, the rear vehicle moves from one side of the blocking arm b3 towards the direction of the unhooking plate b2, when the front vehicle passes through the blocking arm b3 (namely, when the blocking arm b3 is positioned between the front vehicle and the rear vehicle), the fourth push rod cylinder b4 is started, the push rod is contracted to drive the unhooking plate b2 to move along the direction opposite to the running direction of the skip, meanwhile, the blocking arm b3 rotates around the shaft to push out the fixed platform b1, the unhooking plate b2 moves opposite to the skip, the unhooking plate b2 blocks the unhooking handle b201 at the tail of the front vehicle to force the unhooking handle b201 to rotate, so that the traction hook tongue b203 is driven to rotate out of the traction hook ring b202 of the rear vehicle, the front vehicle is separated from the rear vehicle, at the moment, the blocking arm b3 completely rotates out of the fixed platform b1 and abuts. After the front vehicle is pushed to the next procedure by other boosting mechanisms, the push rod of the fourth push rod cylinder b4 is pushed out to drive the blocking arm b3 to retract into the plane of the fixed platform b1 to avoid the rear vehicle, so that the rear vehicle can continue to move forwards, at the moment, the rear vehicle serves as the front vehicle, the skip car hung behind the rear vehicle serves as the rear vehicle, and the blocking unhooking action is repeated.

As a first alternative embodiment of embodiment 2, the unhooking plate b2 can be fixedly mounted on the fixed platform b1, and the unhooking handle b201 at the tail of the front vehicle can collide with the unhooking plate b2 by moving the front vehicle, so as to drive the unhooking handle b201 to rotate to separate the front vehicle from the rear vehicle.

As a second alternative embodiment of example 2, the unhooking plate b2 and the blocking arm b3 may be respectively provided at both sides of the traveling direction of the skip car; further, the unhooking plate b2 and the blocking arm b3 may be driven by separate drives, respectively, and may not necessarily be operated in synchronization. That is, after the front vehicle passes through the barrier arm b3, the barrier arm b3 may extend out of the fixed platform b1 to reach the blocking position in advance, and after the front vehicle drags the rear vehicle to continue to advance, the front vehicle is unhooked by the unhooking plate b2, and the rear vehicle abuts against the barrier arm b3, or the rear vehicle continues to move forward by a small distance under the action of the inertia of movement and abuts against the barrier arm b 3.

As a third alternative embodiment of embodiment 2, the detection switch b8 may be only one, for example, facing the traveling direction of the skip car, and the detection switch b8 is disposed behind the blocking arm b3, and when the detection switch b8 detects that a skip car passes through, the unhooking blocking action is started, for example, after the unhooking blocking action is completed, the time after the front car passes through is calculated, for example, the time for the front car to take the material is at most 15 minutes, then it is determined that the front car has taken the material completely, and the rear car needs to continue to advance to the material taking position after 15 minutes, at this time, the push rod of the fourth push rod cylinder b4 is pushed out, the blocking arm b3 is retracted, and the rear car is retreated, and the rear car is advanced, and when the rear car completely passes through the detection switch b8, the above unhooking blocking action.

As a fourth alternative embodiment of embodiment 2, the rotary lifting system may sequentially lift and rotate a single non-hitched skip without a unhooking blocking mechanism.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
