Crank type elevator with small operation area

Abstract

The invention provides a crank type elevator with a small operation area. The crank type elevator with the small operation area comprises a base, a first supporting arm, a second supporting arm and aworkbench; four side brackets are symmetrically arranged on the two sides of the base; the side brackets are connected with the base by using a welding mode; the top ends of supporting legs are connected with the bottoms of the side brackets by using a hinging mode; pad feet are mounted at the bottoms of the supporting legs by using a hinging mode; one ends of first oil cylinders are connected with the side brackets by using a hinging mode; and the other ends of the first oil cylinders are connected with the supporting legs by using a hinging mode. By improving the crank type elevator, the crank type elevator with the small operation area has the advantages of reasonable structural design, convenient towing, convenient moving and transportation, smaller retracted and folded volume, smallerspace needed by unfolding, small operation area, small use limitation, good buffering and protecting effect, smaller noise, high operation stability and high practicability; and therefore, problems and shortcomings of an existign device are effectively solved.

Description

technical field [0001] The invention relates to the technical field of lifting machinery and equipment, and more specifically, relates to an articulating arm type lift with a small working area. Background technique [0002] Elevator is a multi-functional lifting mechanical equipment, usually used for rescue and decoration, etc. The development of elevators is at a peak state. Since most manufacturers or individuals choose multi-storey buildings in order to improve the utilization rate of the site, Therefore, a device is needed to facilitate the lifting and lowering of goods. Due to the high cost of ordinary elevators and low bearing capacity, it is not suitable for loading goods of tens of tons or hundreds of tons, so a hydraulic lift with high bearing capacity has been developed to assist Production and shipment of goods. The elevator is safe and has a large load capacity, and it is easy to maintain, which makes this special industry develop faster. [0003] Affected by ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a crank arm type elevator with a small working area to solve the problem that the existing elevator proposed in the above background technology is affected by its structure and requires a large space during operation, so as to ensure that the support arm is unfolded. To achieve effective lifting operations, the limitations of use are relatively large, and it often occurs that the working space cannot be satisfied and the effective lifting cannot be achieved. In addition, the support arms and brackets of the existing crank arm lifts are not equipped with buffer protection mechanisms. The support arms and When the bracket shrinks and falls, it often collides with the main body of the device, and the equipment is prone to damage and deficiencies
