Problems solved by technology
[0002] When loading or unloading special equipment on a special vehicle, it is necessary to use a lifting mechanism to perform lifting, lowering or flipping actions on some special equipment. The fulcrum of the existing single fixed lifting mechanism in contact with the equipment is fixed and cannot be changed. During the process of lifting, lowering or flipping special equipment, sometimes a large instantaneous impact force will be generated on the fixed point or support point, and it is easy to cause impact damage and dead point jamming

The invention discloses a linkage type connecting rod lifting mechanism which comprises a horizontal screw rod and a shell body. The horizontal screw rod penetrates through the shell body and is installed in a positioning hole of the shell body, and the left end of the horizontal screw rod is locked by a horizontal positioning nut. The linkage type connecting rod lifting mechanism is characterized by further comprising a transmission device and a retracting device. The contact supporting point of a linkage lifting and positioning mechanism and a device is changeable so as to reduce impact damage and avoid the point blocking phenomenon. The linkage type connecting rod lifting mechanism has the advantages of being low in space requirement, reliable in mechanism connection, easy to lift and drop, simple in machining, manufacturing and assembling of parts and the like.
Description
technical field [0001] The invention relates to a linkage type connecting rod lifting mechanism, which belongs to the technical field of equipment machinery. Background technique [0002] When loading or unloading special equipment on a special vehicle, it is necessary to use a lifting mechanism to perform lifting, lowering or flipping actions on some special equipment. The fulcrum of the existing single fixed lifting mechanism in contact with the equipment is fixed and cannot be changed. During the process of lifting, lowering or flipping special equipment, sometimes a large instantaneous impact force will be generated on the fixed point or support point, and it is easy to cause impact damage and dead point jamming. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a linkage type connecting rod lifting mechanism, the fulcrum of this linkage lifting and positioning mechanism in contact with the equip...
