Abstract

This invention discloses a method for designing hydraulic support ram, which comprises the following steps: a) dividing the ram to short ram, integral long ram and split long ram; b) for short ram and integral long ram, ascertaining their cross-sectional area size according to the bore of push jack connecting to said rams; the length within given size range form series with a certain interval; the change of elements length which are corresponding to each length will be listed in the component diagram, and each varied size is corresponding to a certain letter; c) for split long ram, fixing the size of rear ram, varying the size of front ram to change the total length of split long ram; wherein the front ram is designed according to said short ram in step b.

Description

technical field

[0001] The invention relates to a hydraulic support for supporting equipment in a fully mechanized coal mining face, in particular to a design method for a push rod of the hydraulic support. Background technique

[0002] The push rod in the hydraulic support is located in the middle gap of the base, placed on the bottom plate, and connected with the moving jack and the connecting head through the pin shaft to form a moving device, so as to realize the forward movement of the support itself and the conveyor.

[0003] Due to the complex geological conditions, there are many structural forms of hydraulic supports, which are affected by many uncertain factors, resulting in various forms of push rods. According to the form, the push rod can be divided into two categories: long push rod and short push rod, which are generally box-shaped structural parts welded by steel plates. The long push rod is further divided into an integral box-type long push rod and a split...
