Abstract

The invention relates to a hydraulic driving control device of a hoister and a manufacture method thereof. The hydraulic driving control device comprises a hoister structure, a hydraulic cylinder, a notch positioning plate, a structural tube, a guide pipe, a guider, a traction pulley seat as well as a traction pulley, a pushing pulley seat as well as a pulley and a piston connection device, and has the location guiding balance control function; a hydraulic driving transmission control device of the hoister, which has structural balance control and locating guide function, is implemented; a hydraulic driving mechanism which realizes the single-cylinder pushing-pulling bi-directional action, the lifting running and the stroke amplification and the operation mechanism are adopted; when ascending, a hydraulic driving piston pushes the guider to lift a drawing chain to draw a bearing structure to move upwards; and when descending, the hydraulic driving piston pulls the guider, and the drawing chain draws the bearing structure to move downwards. The lifting drive form is changed, the power is small, the energy consumption is low, the cost is low, the structure is simple, safe and reliable, the operation is smooth, and the hydraulic driving control device is suitable for the installation and application on multiform hydraulic hoisters.

Description

(1) Technical field:

[0001] The invention relates to a hydraulic drive control device for a hoist and a manufacturing method thereof. (two) background technology:

[0002] Existing hydraulic lifting and lifting machines are all realized by piston straightening or lifting, which cannot meet the lifting and lifting operation of small cylinder diameter and large stroke hydraulic drive that requires heavy objects. The reason is that the diameter is thin, the piston rod is long, and the operation time Swing occurs, the hydraulic transmission mechanism does not have the function of two-way driving, and loses use value. (3) Contents of the invention:

[0003] The invention provides a hydraulic drive control device for a hoist and a manufacturing method thereof, which is a hydraulic drive control device composed of a hoist structure, a guide pipe, a guide, a hydraulic cylinder, and the like.

[0004] The manufacturing process of the present invention is: hoist structure manufactu...
