In a kind of situation, be reduced to described the first desired location if detect the piston rod of described locking cylinder 51, then can stop to carry out the contracting operation of described locking cylinder 51.Certainly, also can not stop to carry out the contracting operation of described locking cylinder 51.Indentation can also be continued when in this case, the piston rod of locking cylinder 51 is reduced to the first desired location until reach maximum indentation amount or darker certain position than the first desired location.
In releasing process, if run into some faults, for example release oil cylinder 52 piston rod that causes release oil cylinder 52 that breaks down can not stretch out the measure that then need to indicate or report to the police faulty condition in these situations.According to an embodiment of the present utility model, the method can also comprise if the piston rod of described release oil cylinder 52 reaches described the second desired location in the schedule time when the piston rod from described release oil cylinder 52 begins to stretch out, and then indicates described latching device 50 releases success; If the piston rod of described release oil cylinder 52 does not reach described the second desired location in the schedule time when the piston rod from described release oil cylinder 52 begins to stretch out, then indicate described latching device 50 releases failure.
More than be to describe embodiment of the present utility model for the releasing process of latching device 50, the below will describe embodiment of the present utility model for the locking process of latching device 50.
Fig. 5 is the diagram of circuit for the control method that has surpassed system according to embodiment of the present utility model.With reference to figure 1, Fig. 2 A-2B and Fig. 5, according to an embodiment of the present utility model, surpass system and can comprise super lift winch 55 and latching device 50, this latching device 50 comprise side plate 59, locking cylinder 51, release oil cylinder 52 and can with the ratchet 54 of described super lift winch 55 coaxial rotation, one end of this locking cylinder 51 and release oil cylinder 52 and described side plate 59 articulate, one end of the piston rod of release oil cylinder 52 and this locking cylinder 51 articulate, piston rod one end of this locking cylinder 51 is connected with stop pin 53, and described control method can comprise:

Whether the piston rod that detects this locking cylinder 51 reaches the 3rd desired location; And
When the piston rod that detects described locking cylinder 51 reached the 3rd desired location, the piston rod that stops described locking cylinder 51 stretched out.
In addition, in the process that the piston rod of controlling described locking cylinder 51 stretches out, make the piston rod indentation of described release oil cylinder 52.
Further, this control method can also comprise:
In the process that the piston rod of described locking cylinder 51 stretches out, can detect the locking pressure of this locking cylinder 51, this locking pressure is the pressure that described ratchet 54 imposes on described stop pin 53;
Reach described the 3rd desired location if before the described locking pressure that detects reaches the first pressure set points, detected the piston rod of described locking cylinder 51, then indicate described latching device 50 to lock unsuccessfully.
Can detect by position detecting device the motion of the piston rod of locking cylinder 51.For example can utilize the inductive switch that is arranged on the locking cylinder 51.When piston rod movement to the three desired location of locking cylinder 51, this inductive switch is triggered and moves, thereby produces a signal (being described the 3rd position detection signal in back).The 3rd desired location can be set flexibly according to actual conditions, as long as stop pin 53 finally can enter into the groove of ratchet 54 fully when the piston rod of locking cylinder 51 reached the 3rd desired location.
Detection locking pressure is in order between the groove of understanding ratchet 54 and the stop pin 53 great application force to be arranged, just can be considered as successfully locking because the application force between groove and the stop pin 53 need to reach certain value.The detection of locking pressure can be finished by the pressure sensor that for example is arranged in the locking cylinder 51.Pressure sensor is determined the size of the application force between groove and the stop pin 53 by the pressure that detects hydraulic oil in the locking cylinder 51.It will be appreciated by persons skilled in the art that for detection of the locking mode of pressure or device and be not limited to pressure sensor in the locking cylinder 51.
The first setup pressure value can be the groove that successfully locks desired ratchet 54 and the minimum value of the application force between the stop pin 53.If the piston rod of locking cylinder 51 has reached the 3rd desired location when locking pressure does not also reach the first setup pressure value, the piston rod of locking cylinder 51 had not reached the position when then explanation locking pressure did not also meet the requirements of force value, can't continue locking, this moment, indication locked unsuccessfully.
When locking pressure reaches the first setup pressure value, need also to judge whether stop pin 53 can enter in the groove of ratchet 54.Therefore, according to further embodiment of the present utility model, control method can also comprise:
Reach in the situation of described the first pressure set points at described locking pressure, detect the groove whether described stop pin 53 enters into described ratchet 54; And
If detect the groove that described stop pin 53 enters into described ratchet 54, then indicate described latching device 50 to lock successfully; And if detect the groove that described stop pin 53 does not enter into described ratchet 54, then indicate described latching device 50 to lock unsuccessfully.
Stop pin 53 enters into the detection of the groove of ratchet 54 also can pass through position detecting device, and for example inductive switch is carried out.When stop pin 53 entered into groove, inductive switch was triggered, and sent a position detection signal.
In addition, before the piston rod of locked cylinder begins to stretch out, also may need tension to surpass steel rope 30, therefore, the method can also comprise:
Carry out the rope closing operation of described super lift winch 55;
Detect the tensile force that has surpassed steel rope 30; And
Reach at the tensile force that detects in the situation of the second pressure set points, stop to carry out the rope closing operation of described super lift winch 55.
The tensioning force measurements that surpasses steel rope 30 can be carried out by pressure-detecting device (for example being positioned at the pressure sensor at super lift winch 55 places).The second pressure set points can be for locking the desired tensile force that has surpassed steel rope 30.
Surpassed system and can also comprise having surpassed mast and be used for having driven and surpass the amplitude oil cylinder 70 that mast rotates around principal arm 10, usually when conducting the locking operations requirement to have surpassed mast vertical with principal arm 10 maintenances.Therefore, described control method can also comprise:
Detect the described mast that surpassed and whether keep vertical with described principal arm 10; And
Do not keep vertical with described principal arm 10 if detect the described mast that surpassed, then operate described amplitude oil cylinder 70 actions, so that the described mast that surpassed keeps vertical with described principal arm 10.
Whether also can adopt position detecting device (for example, be arranged on the principal arm 10 inductive switch) to realize with the detection that principal arm 10 keeps vertical to having surpassed mast.When having surpassed mast and principal arm 10 and keep vertical, inductive switch is triggered, and sends a position detection signal, and it is vertical with principal arm 10 that indication has surpassed mast.
