Embodiment Construction

[0012] Embodiment of the present invention: the structure of the convenient lifting device of the hydraulic support is as follows figure 1 As shown, it includes two I-steel beams 1, the distance between the two I-steel beams 1 is 1.6m, a fixed tray 2 is arranged on the upper part of the two ends of the I-steel beam 1, and a Two symmetrically distributed lifting lugs 8 (the width of the lifting lugs is 110mm, the length is 130mm, the diameter of the middle hole is 45mm, and the supporting pins are Ф40 pins); It is determined by the roadway height of the transport trough of the working face. In this embodiment, the height of the roadway of the transport trough of the fully mechanized mining face is 2m, and the required lifting height is 400mm. Therefore, the length of the support jack used must meet the requirements, that is, the extension of 400mm The rear distance is less than 1.8m, so the ZY2100 / 11 / 22A type hydraulic support push jack is the most suitable), the telescopic par...

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,...
