Method for fixing, hoisting and carrying hydraulic support pushing rod

Abstract

The invention provides a method for fixing, hoisting and carrying a hydraulic support pushing rod, and aims at avoiding the hoisting difficulty caused by hanging down of the middle of the pushing rod. The method is characterized in that a special hanging hook device is independently manufactured, wherein the special hanging hook device comprises two fixing hanging hooks and two fixing rings; each fixing hanging hook comprises an upper horizontal hook, a vertical rod and a lower horizontal hook; the included angle between each upper horizontal hook and the corresponding intermediate vertical rod, the included angle between each intermediate vertical road and the corresponding lower horizontal hook, and the included angle between each upper horizontal hook and the corresponding lower horizontal hook are 90 degrees; the fixing rings are steel pipes and are welded in the center of the top surface of the hydraulic support pushing rod; the upper horizontal hooks of the two fixing hanging hooks are correspondingly clamped to the upper top surfaces of a left hydraulic support base and a right hydraulic support base; the two lower horizontal hooks are correspondingly inserted into two fixing rings on the top surface of the pushing rod, so that the pushing rod and the support bases are fixedly connected as a whole; the hoisting hooks are mounted on hoisting loading and unloading holes in the hydraulic support bases; then a steel wire rope is connected and stretched by a crane for hoisting; the hydraulic support parallelly moves onto a loading handcart or is hoisted onto an automobile for transporting.

Description

technical field [0001] The invention relates to a lifting and conveying method for fixing a push rod of a hydraulic support. Background technique [0002] At present, during the lifting process of the hydraulic support, the push rod cannot be in a straight line because the connection is fixed by a pin shaft, and the knuckle is V-shaped, and the lifting height is more than 1.5 meters higher than the support base to move the support. During the downhole transportation, because the push rod of the support and the base form a V shape, the suspension distance between the support base and the trolley is relatively high, it is difficult to load and fix the hydraulic support, and it also causes problems such as long loading and unloading time. Workers work under the support with high lifting height for a long time, which also has relatively large safety hazards. If the crane fails or the wire rope breaks, it will produce a large impact, resulting in equipment damage and personal acc...

Problems solved by technology

During the downhole transportation, because the push rod of the support and the base form a V shape, the distance between the support base and the trolley is relatively high, it is difficult to load and fix the hydraulic support, and it also causes problems such as long loading and unloading time

Workers work under the bracket with a high lifting height for a long time, which also has a relatively large safety hazard. If the crane fails or the wire rope breaks, it will produce a large impact, causing equipment damage and personal accidental injury and other accidents.
