The described pin rod 7 of carrying can have various suitable structures.As shown in Figure 4, carry pin rod 7 for convenience and carry out oscillating motion, preferably, the second horizontal extension 36 that the described first horizontal extension 48 of carrying pin rod 7 and having vertical part 47, be connected with the upper end of described vertical part 47 is connected with lower end with described vertical part 47, the described first horizontal extension 48 and the described second horizontal extension 36 stretch out in the opposite direction, and the described first horizontal extension 48 passes hinge bearing 46 fixedlys connected with the hinge of third connecting rod 20.Generally, described vertical part 47, the first horizontal extension 48 and the second horizontal extension 36 are integrally formed.
Next train coupler arranged lock portion is carried out brief description.As Fig. 9 and shown in Figure 10, train coupler arranged 38 by pin 39 lockings, and the top of pin 39 is connected with pull bar 41 by iron chains 40.When needs are opened hitch, can thereby pass through iron chains 40 pin 39 be proposed, and then hitch 38 is opened with the vertical part of direction rotating rod 41 outside the paper of hand in Fig. 9.
Described hitch opening device can be installed in (for example front end of the big arm of car puller) on support or the miscellaneous equipment by fastening pieces such as bolts.
The working procedure of above-mentioned hitch opening device is described below in conjunction with Fig. 1 to Figure 12.The working procedure of this hitch opening device is divided into following three phases: the phase I, march forward to reaching swing feed; Second stage, pin is carried in rotation; Phase III, return the stage.Respectively this three phases is described below.
Phase I:
Because the initial position of hitch opening device can only be positioned at the level outside of pull bar 41, just must will carry the inboard that pin rod 7 extend into pull bar 41 so will propose the pin operation.The action of phase I mainly is to realize carrying the inboard that pin rod 7 extend into pull bar 41, proposes the pin action for the rotation of next stage and prepares.In the phase I, first slide block 8 and active sliding block 3 are by latch 10 lockings, driving mechanism 1 drives active sliding block 3 and do straight line motion on guide rail 4, simultaneously, active sliding block 3 drives first slide block 8 and second slide block 9 is done straight line motion together on guide rail 4, as shown in figure 11, because first slide block 8 is pivotally connected by first connecting rod 29 and sidepiece 32, so do in the straight-line process at active sliding block 3 drive first slide blocks 8 and second slide block 9, first connecting rod 29 can promote first slide block 8 and swing to the side, first slide block 8 drives guide rail 4 simultaneously and each parts of being installed on the guide rail 4 are swung around bearing pin 28, the position of its full swing angle is that the elongation line of first connecting rod 29 is done straight-line vertical position along the line with first slide block 8, this full swing angle is θ, when first slide block 8 when position I moves to position II, whole feed movement is forward finished, and stroke is H.Obviously, the full swing angle of guide rail 4 can be changed, the demand that pin rod 7 swings in pull bar 41 inboards will be put forward thereby satisfy by the length that changes first connecting rod 29.Make by the motion of the above-mentioned feed movement of finishing simultaneously forward and swing feed and to carry the inboard that pin rod 7 moves to pull bar 41, move and prepare thereby carry pin for the rotation of second stage.
Second stage:
Phase I enters second stage after finishing.In second stage, unlock piece 11 is with latch 10 jack-up, thereby remove the locking between the active sliding block 3 and first slide block 8, unlock piece 11 stops first slide block 8 and second slide block 9 to travel forward simultaneously, driving mechanism 1 continues to drive active sliding block 3 and does straight line motion forward, and first slide block 8 and second slide block, 9 transfixions, when active sliding block 3 is done straight line motion forward, promote third connecting rods 20 by second connecting rod 19 and do clockwise rotation around the pivotally connected point of itself and second slide block 9, thereby drive the pin rod 7 of carrying of fixedlying connected and do clockwise rotation with third connecting rod 20, thereby drive pull bar 41 rotations, pin 39 is proposed, and then hitch 38 is opened.Continue to do forward in the straight-line process in active sliding block 3, just carry in the pin process in the rotation of carrying pin rod 7, active sliding block 3 is depressed the other end of lever 24, make second stop member 27 engage with first stop member 26, thereby effectively first slide block 8 is blocked, stop that first slide block 8 and second slide block 9 are toward swivel motion.As shown in figure 12, after the phase I finished, the horizontal angle between second connecting rod 19 and hinge A and the hinge B was α 1, and the horizontal angle between third connecting rod 20 and hinge A and the hinge B is γ 1.After proposing pin action and finishing, the horizontal angle between second connecting rod 19 and hinge A and the hinge B is α 2, and the horizontal angle between third connecting rod 20 and hinge A and the hinge B is γ 2.Then the angle of swing of third connecting rod 20 is γ 2-γ 1=β, be synchronized with the movement with third connecting rod 20 owing to carry pin rod 7, and also be β so put forward the angle of swing of pin rod 7.Active sliding block 3 moves to position III from position II, and stroke is H1.Putting forward the angle of swing of pin rod 7 can regulate by the stroke that changes active sliding block 3, and its concrete size should be decided according to the actual required angle of pin of carrying.
Phase III:
After second stage is finished, enter the phase III.In the phase III, driving mechanism 1 drives active sliding block 3 and does the straight line return movement, third connecting rod 20 is done around the pivotally connected point of itself and second slide block 9 and is rotated counterclockwise motion, thereby drive the pin rod 7 of carrying of fixedlying connected and do counterclockwise return movement with third connecting rod 20, in this process, active sliding block 3 can disengage with the other end of lever 24, thereby second stop member 27 is fallen, and has removed first slide block 8 and second restriction of slide block 9 on Return-ing direction.When active sliding block 3 moves to position II, contact with first slide block 8, and drive first slide block 8 and second slide block 9 returns together, latch 10 falls simultaneously, and the active sliding block 3 and first slide block 8 are locked together.Owing to be subjected to the restriction of first connecting rod 29, first slide block, 8 drive guide rails 4 and each parts that are installed on the guide rail 4 are swung around bearing pin 28, make and carry pin rod 7 swings to pull bar 41 from the inboard of pull bar 41 the outside, first slide block 8 turns back to initial position I simultaneously.
