Background technology

In the prior art, scissors lift device is the plant equipment being generally used for vertical lift people or thing, can be extensive For patient's wheelchair, maintenance of equipment, mechanical erection etc..Existing scissors lift device on startup, due to scissor with ground Face angle is less, needs the biggest power, and this often makes driving means overvoltage or burns, it is impossible to realizes the lifting of device, deposits In hidden danger.

Utility model content

Technical problem to be solved in the utility model is to overcome prior art defect, it is provided that one is particularly easy to regard to energy Realize the lowering or hoisting gear of elevating function.

In order to solve above-mentioned technical problem, a kind of lowering or hoisting gear that this utility model provides, including top, bottom and fixing In the driver element of bottom, connect the elevating mechanism of described top and bottom；Described elevating mechanism includes front scissor, rear shears Foot；Described front scissor is fixed on bottom, and described rear scissor is free end, is provided with push rod between rear scissor；Parallel across The screw mandrel of described push rod, its one end is connected with driver element, and the other end is fixed on bottom；Wherein, described screw mandrel is cased with voussoir And pushing block；It is provided with push rod between described front scissor and the pin joint of rear scissor；When described elevating mechanism rises, described push rod Being positioned at described voussoir minimum point, described drive unit drives screw mandrel rotates, and screw mandrel drives voussoir and pushing block to move simultaneously, voussoir Inclined-plane makes push rod upward sliding and orders about elevating mechanism and be lifted up；When described push rod reaches the inclined-plane peak of voussoir, pushing block Laminating push rod and drive elevating mechanism continue up be promoted to the highest.

Further, it is provided with at least one upper roller bottom described push rod.

Further, bottom described voussoir, it is provided with that at least one pair of is symmetrical, and is positioned at the bottom roller on the right side of voussoir peak.

Further, described bottom is provided with a pair guide rail matched with rear scissor, and rear scissor can be led described in edge Rail moves in parallel.

Further, described pushing block bottom adhe has plastic tab.

Further, at least one pair of symmetrical roller it is provided with bottom described pushing block.

The beneficial effects of the utility model are: (1), the inclined-plane of voussoir make push rod slide, it is easy to ground orders about elevator Structure is lifted up；(2), the upper roller of push rod, the bottom roller bottom voussoir, the plastic tab bottom pushing block or roller, further Reduce frictional force, make elevating mechanism more easily increase；(3) setting of the guide rail matched with rear scissor, makes lowering or hoisting gear Stability is kept in lifting process.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is elaborated.

If Fig. 1 is to shown in 5, this utility model lowering or hoisting gear, including top 1, bottom 9, is fixed on the driver element of bottom 9 6；Described driver element 6 includes motor and decelerator；Connecting the elevating mechanism 2 of described top 1 and bottom 9, elevating mechanism 2 includes Front scissor 11, rear scissor 12；Push rod 13, push rod 13 it is provided with between described front scissor 11 and the pin joint of rear scissor 12 Bottom is provided with a pair symmetrical upper roller 3；Described bottom 9 is provided with a pair guide rail 10 matched with rear scissor 12, leads Rail 10 is provided with stopping means 15, and rear scissor 12 can move in parallel along described guide rail 10；Described front scissor 11 is fixed on leads On rail 10；It is provided with push rod 7 between described rear scissor 12.

Described motor connection one is fixed on bottom 9 parallel across the screw mandrel 4 of described push rod 7, screw mandrel 4 other end；Described silk Bar 4 is cased with voussoir 5 and pushing block 8；It is provided with two bottom described voussoir 5 and mutually symmetrical with bottom roller 14, one pair of which are positioned at voussoir 5 On the right side of inclined-plane peak.

As shown in Fig. 6, Fig. 1, Fig. 7, when this utility model lowering or hoisting gear rises, described push rod 13 is positioned at described voussoir 5 Inclined-plane minimum point；Starting motor, drive screw mandrel 4 to rotate, screw mandrel 4 drives voussoir 5 and pushing block 8 to move simultaneously, the inclined-plane order of voussoir 5 The upper roller 3 of push rod 13 is ramped up rolling, and orders about elevating mechanism 2 and be lifted up；The upper roller 3 of described push rod 13 reaches During the inclined-plane peak of voussoir 5, pushing block 8 fit push rod 7 and drive elevating mechanism 2 continue up be promoted to the highest.

With process when rising to anti-when this utility model lowering or hoisting gear declines.

The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art For art personnel, can also make some improvement on the premise of without departing from this utility model principle, these improvement also should be regarded as Protection domain of the present utility model.
