Convenient and fast hydraulic support lifting device

Abstract

The invention discloses a convenient and fast hydraulic support lifting device. The convenient and fast hydraulic support lifting device comprises two I-steel beams, wherein the upper parts of two ends of each I-steel beam are provided with fixed pallets, and the bottom of each I-steel beam is provided with two lifting ears which are symmetrically distributed. The convenient and fast hydraulic support lifting device is additionally provided with a pushing jack, wherein a telescopic part of the pushing jack is downward, the end of the telescopic part of the pushing jack is provided with a hook-headed pin hole, the hook-headed pin hole is connected with a lifting hook head, the top of the pushing jack is provided with a fixed seat, the fixed seat is provided with pin holes, through pins of the lifting ears pass through the pin holes, and a fixed ear of the pushing jack and the fixed seat are connected with each other through a fixed pull rod. The convenient and fast hydraulic support lifting device adopts the structure that the pushing jack is connected to the I-steel beams to enable the pushing jack to be used as a lifting tool, so that in the whole lifting process, a fixed 6.8-ton support can be lifted through a control button only by a driver skilled in an emulsion pump, and the convenient and fast hydraulic support lifting device is convenient in operation, saves a large number of human resources, and is safe and reliable.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to a convenient lifting device for a hydraulic support. Background technique [0002] At present, in terms of fully mechanized mining technology in coal mines, the most critical part of the hydraulic support is the lifting and loading of the hydraulic support. The height of the / 22A hydraulic support is 1100-2200mm, and the height of the mining face is 1550-2000mm. Therefore, before transporting out of the mining face and loading on the truck, ensure that the height of the support itself is low enough to ensure the lifting and normal transportation of the support. [0003] Taking Anshun Coal Mine in Guizhou as an example, the 9103 working face of Anshun Coal Mine adopts comprehensive mechanized mining technology. The working face has a transport trough length of 1010m, a track trough length of 925m, an area of ​​163978m2, an average mining height of 1.6m, and recoverable reserves of 383,...

AI Technical Summary

Problems solved by technology

The hydraulic support used in the 9103 fully mechanized mining face of Anshun Coal Mine is ZY2100 / 11 / 22A hydraulic support, and the weight of each hydraulic support is 6.8t. The hydraulic support needs to be lifted first before loading the hydraulic support. The current lifting is to work , is to use the lifting device fixed on the top plate (such as: hand chain hoist, column return device, etc.) is directly fixed on the anchor rod or ladder beam, but the weight of the lifted weight does not exceed 2 tons, and now the working surface is lifted The weight of the hydraulic support is 6.8t, so the lifting method used in the prior art cannot be applied
