The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further:
Such as Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of Bidirectional supporting locking mechanism of avoiding movement interference, comprise lock hook 1, sliding support post 2, upper connecting rod 3, lower link 4, hydraulic cylinder 5, spring 6, limited block 7, rotating shaft 8 on the hydraulic cylinder, connecting rod rotating shaft 9, lock hook bearing 10, lock hook rotating shaft 11, hydraulic cylinder bearing 12, hydraulic cylinder lower rotary shaft 13, lock hook bearing 10 is fixedly mounted on the chassis of container, lock hook 1 one ends are hinged by lock hook rotating shaft 11 and lock hook bearing 10, can rotate around lock hook rotating shaft 11, sliding support post 2 quantity are 2, a thick end is set in the through hole of interior up and down two lock faces of lock hook 1 rectangular opening, the other end respectively with upper connecting rod 3, lower link 4 is hinged by connecting rod rotating shaft 9, upper connecting rod 3, the other end of lower link 4 is coaxial hinged by 8 threes of rotating shaft on the hydraulic cylinder with hydraulic cylinder 5 one ends; The other end of hydraulic cylinder 5 and hydraulic cylinder bearing 12 are hinged by hydraulic cylinder lower rotary shaft 13; Limited block 7 places on the lock hook 1 rectangular opening sidewall, and fixes by screw, and the center line of limited block 7 short transverses overlaps with the center line of lock hook 1 rectangular opening sidewall short transverse; Spring 6 is stage clip, and quantity is 2, is installed in respectively in the endless groove on the lock hook 1 rectangular opening upper and lower surface, respectively with the 2 coaxial installations of two sliding support posts.
The course of work of the present utility model:
Such as Fig. 1 and shown in Figure 7, when lock-out state, hydraulic cylinder 5 is in the full extension state, hydraulic cylinder 5 promotes two up and down two lateral movements of sliding support post 2 by upper connecting rod 3 and lower link 4, the thrust that the sliding support post 2 of upside overcomes spring 6 moves upward and compresses with the upper surface of launcher column lock slots, the thrust that the sliding support post 2 of downside overcomes spring 6 moves downward and compresses with the lower surface of launcher column lock slots, realizes the Bidirectional supporting locking.Under the lifting operating mode, the launcher column has the upwards trend of motion, the sliding support post 2 of downside is under pressure, transfer loads to by lower link 4 and upper connecting rod 3 on the sliding support post 2 of upside, the sliding support post 2 of upside transfers loads on the lock hook 1 by the shaft shoulder, lock hook 1 transfers loads on the chassis of container by lock hook bearing 10, and by above-mentioned transmittance process, slinger's working condition loading of launcher column finally is delivered on the chassis of container; Under pile dress operating mode, the launcher column has the trend of downward motion, the sliding support post 2 of upside is under pressure, transfer loads on the sliding support post 2 of downside by upper connecting rod 3 and lower link 4, the sliding support post 2 of downside transfers loads on the lock hook 1 by the shaft shoulder, lock hook 1 transfers loads on the chassis of container by lock hook bearing 10, and by above-mentioned transmittance process, pile dress operating loading of launcher column finally is delivered on the chassis of container.
As shown in Figure 5, in releasing process, hydraulic cylinder 5 shrinks, and connecting rod 3 and lower link 4 swing to the right in the drive, and the latching force that two sliding support posts 2 are born reduces, two sliding support posts 2 under the promotion of spring 6 to resetting, the sliding support post 2 of upside moves downward, and the sliding support post 2 of downside moves upward, and the supporting surface of two sliding support posts 2 separates with the launcher column, until the shaft shoulder enters sliding support post 2 reset modes with till limited block 7 contacts.Sliding support post 2 resets so that the sweeping space of locking mechanism rotation process diminishes, and avoids interfering with the launcher column in the motion process.
As shown in Figure 6, on the basis of sliding support post 2 reset modes, hydraulic cylinder 5 continues to shrink, and drives lock hook 1 around clockwise rotation of lock hook rotating shaft 11, makes the locking mechanism release.
