Abstract
The utility model provides a lifting and lowering device with amplifying hydraulic stroke, wherein, a hydraulic system device which is composed of a hydraulic cylinder and a piston is arranged on a ground beam; the top part of the piston is provided with two symmetrical fixed pulleys; both ends of a bottom beam and a corresponding beam frame ceiling are respectively provided with foundation pulleys and ceiling pulleys; ends of steel cables respectively wind through the ceiling pulleys, the foundation pulleys and piston pulleys and then are fixedly connected to the bottom beam under a hydraulic system, and other ends of the steel cables are fixed with the lifting and lowering device. In such a way, a fixed pulley block is formed. The piston stroke of the hydraulic system is amplified by a pulley block mechanism. The utility model decreases depth of the hydraulic system device, reduces quantity of execution of construction work, saves construction cost of a lifting and lowering mechanism, simultaneously improves stability and safety of the mechanism, easily realizes a stereo multi-layer lifting and lowering mechanism and is particularly suitable for lifting and lowering mechanisms for underground garages, mechanical repair workshops, lifting and lowering racks of supermarkets, etc.
Description
Technical field:
The utility model is the improvement to existing lifting mechanism, and it is arranged is to disclose a kind of jacking system that amplifies hydraulic stroke that has, and belongs to mechanical elevating mechanism technical field.
Background technology:
Existing lifting mechanism is that hydraulic efficiency pressure system is directly acted on the lifting table, about the lifting travel drive platform by hydraulic efficiency pressure system, because lifting mechanism on the ground, therefore, the stroke height of hydraulic efficiency pressure system must be greater than 2 times of adjustable height, could guarantee the normal lifting of platform, just hydraulic efficiency pressure system must be installed in 2 times of underground to adjustable height, increase difficulty to construction, strengthened construction costs, level of stability reduces simultaneously, particularly for the underground jacking system of layer stereo lifting mode, almost can't realize.
Summary of the invention:
The utility model provides a kind of jacking system that amplifies hydraulic stroke that has, and has solved because the hydraulic efficiency pressure system lifting travel is excessive, and difficulty of construction increases, the problem of poor stability.
Technical solution of the present utility model is as follows: by hydraulic actuating cylinder, the hydraulic system that piston constitutes is on grade beam, the top of piston is provided with two fixed pulleys of symmetry, two ends and cooresponding beam frame ceiling at bottom girder, be respectively equipped with the lower margin pulley, the ceiling pulley, one end of steel rope is walked around the ceiling pulley respectively, be fixedly connected on behind lower margin pulley and the piston pulley below the hydraulic efficiency pressure system on bottom girder, the other end is fixing by jacking system, constitute the fixed pulley group, the stroke height of piston can be enlarged into twice by the fixed pulley group, therefore, it is the distance that liftable doubles length that hydraulic efficiency pressure system need not increase piston length, has satisfied the technical requirements of the big stroke of small distance.
Also can between hydraulic piston and steel rope, add the pulley gear of multistage symmetry, make the further multistage amplification of piston stroke.
The utility model is specially adapted to lifting mechanisms such as basement garage, mechanical repair plant, supermarket alighting gear.
Good effect of the present utility model is: by assembly pulley mechanism the piston stroke of hydraulic efficiency pressure system is amplified, greatly reduce the device degree of depth of hydraulic efficiency pressure system, reduced the building operation amount, saved the laid down cost of lifting mechanism, improve mechanism stability and safety simultaneously, and be easy to realize the stereoscopic multi-layer lifting mechanism.
