Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
Lifting gear in the large-scale elevation and subsidence mechanical needs aloft to realize hanging, and thereunder can also carry out other operation, perhaps parks miscellaneous equipment.
But in the prior art, there is defective in the keying structure of its suspension arrangement, and it is unreliable to lock, and brings hidden danger to safety.Though some can realize locking, its complex structure, inconvenient operation.
Structure of the present utility model as shown in Figure 1 is a kind of locking mechanism of elevation and subsidence mechanical, and described elevation and subsidence mechanical is provided with frame 1, is used for the lifting supporting plate of lifting, and described elevation and subsidence mechanical also is provided with locking mechanism 5.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realize the goal of the invention of the reliable locking of suspension arrangement when hovering of elevation and subsidence mechanical, the technological scheme that the utility model is taked is:
As shown in Figure 1, the locking mechanism of elevation and subsidence mechanical provided by the utility model, the structure of described locking mechanism 5 is: vertical supporting plate boom stick 3 and its bottom and described lifting supporting plate are set on the described lifting supporting plate are fastenedly connected; Described locking mechanism 5 is established vertical locking push rod 11, pushing rod sleeve 9 and boom stick cover 6, described supporting plate boom stick 3 and locking push rod 11 respectively with boom stick cover 6 and pushing rod sleeve 9 for being slidingly matched; Described supporting plate boom stick 3 and the relative side of locking push rod 11 are established the inclined-plane low-angle, that true dip direction is identical respectively.
This structure is the Double Oblique Wedge locking mechanism, utilizes its self-locking action, its locking effect the best.And lock is tight more more in the process of hovering, but can be not stuck, unclamps if desired, can unclamp easily again.
Adopt technique scheme, the suspension arrangement that makes all kinds of elevation and subsidence mechanicals when hovering, lock more reliable, shut-down operation safety, and simple in structure, operation and control make things convenient for.
The setting of concrete structure of the present utility model and being analyzed as follows:
