The specific embodiment
As shown in Figure 1, present embodiment is a kind of built-in hydraulic cylinder locking mechanism, locks pedestal 4 at the top of hydraulic cylinder 7 through the coaxial installation of bolt, this locking pedestal hollow, enclosing cover 5 is installed at the top, forms annular seal space, and lock body 1, locking fairlead 2 and locking bearing 3 are housed in annular seal space.
Lock body 1 and hydraulic cylinder 6 coaxial linking to each other of 7 inner piston rods in the present embodiment, and this lock body 1 can move up and down with piston rod 6.As Fig. 2 ~ shown in Figure 4, lock body 1 is a solid cylinder, evenly is shaped on 4 lock support 101 at its external cylindrical surface upper position, and the side lower position evenly is shaped on 8 guiding tooth I 102 that make progress.
As Fig. 5 ~ shown in Figure 7, locking fairlead 2 internal diameters and lock body 1 column part diameter are basic identical, this locking fairlead inwall is provided with 4 grooves 203 that can supply lock support 101 axially to pass through along fairlead, the top center that locking fairlead 2 is not established the groove position is shaped on and can carves the lock slots 201 that closes with lock support 101, so lock slots 201 differs 45 ° with adjacent notches 203 centers.Locking fairlead 2 bottoms be shaped on 8 can with the guiding tooth II 202 of guiding tooth I 102 engagements on the lock body 1.
Locking bearing 3 is sheathed on the lock body 1 and is positioned at and locks fairlead 2 belows in this example, and lock body 1 can wholely be passed in locking bearing 3.Locking bearing 3 floats with locking pedestal 4 and fixedlys connected, basic fixed is motionless when namely normally moving, and when locking fairlead 2 and locking bearing 3 are not just meshing, can pass through lock body 1 and load, locking bearing 3 is deflected, guarantee to lock fairlead 2 and lock bearing 3 positions of engagement correct.As Fig. 8, shown in Figure 9, locking bearing 3 tops evenly be shaped on 8 can with the guiding tooth III 301 of guiding tooth II 202 engagements on the locking fairlead 2.
When leading 202 engagements of tooth II on lead on the locking bearing 3 tooth III 301 and the locking fairlead 2, lock support 101 correspondences lock fairlead 2 upper locking grooves 201 or groove 203 centers on the lock body 1 in the present embodiment.Guiding tooth III 301 positions are staggered 11.25 ° on the tooth I 102 that leads on the lock body 1 and the locking bearing 3.
The operating principle of present embodiment is as follows:
Lock body 1 is connected with piston rod 6, forms the active traveling mechanism of latch-up structure.
Last latching operation (namely becoming lock-out state from unlocked state): up by lock body 1, it is up to drive locking fairlead 2, locking fairlead 2 takes place around 33.25 ° of axis deflections (45 °-11.25 °) in the drift angle of the tooth of dependence guiding simultaneously I 102, guiding tooth II 202 engagements on guiding tooth I 102 and the locking fairlead 2; Descending behind the lock body 1 up certain distance, locking fairlead 2 simultaneously descending with lock bearing 3 and contact, guiding tooth III 301 on the locking bearing 3 makes locking fairlead 2 take place around 11.25 ° of axis deflections simultaneously, guiding tooth II 202 engagements on guiding tooth III 301 and the locking fairlead 2.Locking fairlead 2 is around the distance of one of axis deflection guiding tooth III 301 in the whole process, i.e. 45 ° of deflections, and lock slots 201 differs 45 ° with adjacent notches 203 centers, so lock support 101 from respective slot 203 location deflections to corresponding lock slots 201 positions.Locking supporting 101 on the lock body 1 cooperates (seeing Figure 10, Figure 11), hydraulic cylinder locking, gate lock with the lock slots 201 of locking fairlead 2.
Take off latching operation and lock class of operation seemingly, lock body 1 is up, drive locking fairlead 2 up (seeing Figure 12), rely on the drift angle of guiding tooth I 102 that locking fairlead 2 is taken place around axis deflection simultaneously, descending behind the lock body 1 up certain distance, locking fairlead 2 simultaneously descending with lock bearing 3 and contact, the guiding tooth III 301 of locking on the bearing 3 make locking fairlead 2 take place to deflect to around the axis simultaneously to take off lock-bit (lock support 101 from corresponding lock slots 201 location deflections to respective slot 203 positions, see Figure 13), locking supporting 101 on the lock body 1 cooperates with the groove 203 of locking fairlead 2, but lock body 1 easy on and off moves, hydraulic cylinder takes off lock, and gate takes off lock.
