Description
Technical field
A kind of elevating mechanism is the utility model is related to, it is particularly a kind of to force closing device and system.
Background technology
The structure of shelter is similar to container, is generally welded by sheet metal, and shelter is generally equipped with carrier vehicle, and one
As be picking-up vehicle, delivered by carrier vehicle to required place, its standard is also to refer to container standard formulation, with container
Compare, shelter has higher mobility, can be field rescue using the various articles of the space configuration of shelter and equipment
Reliable guarantee is provided Deng action.
But the shelter heavier-weight of equipment and object is equipped with, to realize shelter to the loading between carrier vehicle or unload
Under, typically operated by the way of directly lifting by crane, such shelter charge and discharge operations are complex, and the requirement to equipment is higher, no
It is adapted to very much the situation of field rescue action；With the development of technology, a kind of square cabin lifting device is developed, such as Fig. 1 institutes
Show, the square cabin lifting device is provided with two supporting legs, wherein a ground connection supporting leg that ground is stood on for supporting leg（Including inner sleeve 1
With outer tube 3）, another is the shelter bearing 9 fixed with shelter 12, and sets connection pole 6 to connect two supporting legs,
Driving wheel is driven using chain drive, and chain-driving inner sleeve 1 stretches out or withdraw, outer tube 3 is synchronous with shelter bearing 9 rise or
Decline, realize the descending operation of shelter 12.Stable state is kept generally for when allowing shelter to lift or after reaching operating position,
Can be set up on supporting leg and the spacing locking mechanism of connection pole 6, i.e. dead bolt bar 5, one end are hinged with ground connection supporting leg, the other end and
The lockhole set on connection pole 6 coordinates, and keeps the stabilization of two supporting leg relative positions, and then the position of fixed shelter；But should
Problems be present in the setting of locking mechanism：
Locking mechanism needs to open when shelter drops to extreme position, unblock connection pole, so that elevating mechanism is grounded
Supporting leg can collapse toward shelter；And when shelter rises or falls, need to lock the position of connection pole again, to ensure two supporting legs
Relative position it is stable, ensure the stable lifting action of shelter；But in this process, the opening of locking mechanism and locking all need
Very important person is manually operated, inconvenient for operation and need the operating time, and manual operation locking mechanism is also deposited in shelter lifting process
In certain potential safety hazard, it is unfavorable for improving the operational efficiency of lowering or hoisting gear.
Utility model content
Goal of the invention of the present utility model is：Utilized for the position in the lifting process of existing shelter, connecting pole
Locking mechanism enters line-locked operation, or the operation unlocked when shelter drops to extreme position, is all to rely on people manually operated,
Operation is inconvenient and efficiency is low, the technical problem of potential safety hazard be present, there is provided one kind forces closing device and system, the pressure folding
Device will connect branch rod lock automatically when shelter rises or falls, and ensure the stable safety of shelter lifting action；Decline in shelter
