Description
Technical field
The present invention relates to lifting technology field, particularly relate to a kind of lowering or hoisting gear.
Background technology
In the prior art, scissors lift device is the plant equipment being generally used for vertical lift people or thing, can be widely used for patient's wheelchair, maintenance of equipment, mechanical erection etc..Existing scissors lift device is when starting, owing to scissor and ground angle are less, it is necessary to very big power, this often makes driving device overvoltage or burns, it is impossible to realizes the lifting of device, there is hidden danger.
Summary of the invention
The technical problem to be solved is in that to overcome prior art defect, it is provided that a kind of especially easy lowering or hoisting gear that can be achieved with elevating function.
In order to solve above-mentioned technical problem, a kind of lowering or hoisting gear provided by the invention, including top, bottom and the driver element bottom being fixed on, connect the elevating mechanism of described top and bottom；Described elevating mechanism includes front scissor, rear scissor；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 is positioned at described voussoir minimum point, and described drive unit drives screw mandrel rotates, and screw mandrel drives voussoir and pushing block to move simultaneously, and the inclined-plane of voussoir 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 move along described guide rail 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 present invention is: the inclined-plane of (1), voussoir makes push rod slide, it is easy to ground orders about elevating mechanism and is lifted up；(2), the upper roller of push rod, the bottom roller bottom voussoir, the plastic tab bottom pushing block or roller, reduce frictional force further, make elevating mechanism more easily increase；(3) setting of the guide rail matched with rear scissor, makes lowering or hoisting gear remaining stable for property in lifting process.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated.
If Fig. 1 is to shown in 5, lowering or hoisting gear of the present invention, including top 1, bottom 9, is fixed on the driver element 6 of bottom 9；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；It is provided with push rod 13 between described front scissor 11 and the pin joint of rear scissor 12, bottom push rod 13, is provided with symmetrical a pair upper roller 3；Described bottom 9 is provided with a pair guide rail 10 matched with rear scissor 12, and guide 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 guide rail 10；It is provided with push rod 7 between described rear scissor 12.
Described motor connection one is parallel across the screw mandrel 4 of described push rod 7, and screw mandrel 4 other end is fixed on bottom 9；Described screw mandrel 4 is cased with voussoir 5 and pushing block 8；Being provided with two pairs of mutually symmetrical with bottom rollers 14 bottom described voussoir 5, one pair of which is positioned on the right side of the inclined-plane peak of voussoir 5.
As shown in Fig. 6, Fig. 1, Fig. 7, when lowering or hoisting gear of the present invention rises, described push rod 13 is positioned at the inclined-plane minimum point of described voussoir 5；Starting motor, drive screw mandrel 4 to rotate, screw mandrel 4 drives voussoir 5 and pushing block 8 to move simultaneously, and the inclined-plane of voussoir 5 makes the upper roller 3 of push rod 13 be ramped up rolling, and orders about elevating mechanism 2 and be lifted up；When the upper roller 3 of described push rod 13 reaches 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.
