Abstract
The invention discloses a kind of pusher structures suitable for full easy opened hydraulic support foundation, including putter body, are connected in the connector of putter body front end and the advancing jack hinged seat of rear end；The three ply board part that putter body is stacked by upper, middle and lower is constituted；It is opened up along longitudinal direction positioned at the upper surface of middle layer plate fluted, input duct and back liquid pipeline is installed in groove；The plate upper both ends in input duct and back liquid pipeline in upper layer are respectively arranged with feed liquor pipe fitting and liquid back pipe connector, feed liquor pipe fitting and liquid back pipe connector are the helicitic texture for being conveniently replaceable dismounting, and feed liquor pipe fitting and liquid back pipe connector are connected to corresponding input duct and back liquid pipeline sealing respectively.The present invention realizes the hydraulic system of hydraulic support and the piping connection of coal working face hydraulic system by the logical liquid device being built in putter body, sebific duct is effectively prevented between curved frame to the occupancy in pedestrian space, it realizes and smoothly moves frame, provide powerful guarantee for creation intrinsically safe mine.
Description
Technical field
The present invention relates to coal mine fully-mechanized mining working hydraulic supports, more particularly, to suitable for full easy opened hydraulic support foundation
Pusher structure.
Background technique
China is big coal country, and hydraulic support is the main support apparatus of underground coal fully-mechanized mining working, due to it is main into, return
Liquid pipeline arrangement is unreasonable, so that during dropping frame, moving frame pressure piping collision cleft occurs for hydraulic support, highly pressurised liquid is caused to be hurt
Occurrences in human life event；The conventional simultaneously arrangement into, liquid back pipe road occupies pedestrian space, so that operator's normal pass is relatively difficult,
This not only lowers coal work efficiency, and there are security risks.
Summary of the invention
It is an object of that present invention to provide a kind of structures reliably, it is convenient to move frame, section space-efficient is suitable for the hydraulic branch of full easy opened
The pusher structure of frame pedestal.
To achieve the above object, the present invention takes following technical proposals:
Pusher structure of the present invention suitable for full easy opened hydraulic support foundation, including putter body, are connected in the push rod
The connector of ontology front end and the advancing jack hinged seat of rear end；The three ply board part that the putter body is stacked by upper, middle and lower
It constitutes；It is opened up along longitudinal direction positioned at the upper surface of middle layer plate fluted, input duct and liquid back pipe is installed in the groove
Road；The plate upper both ends in the input duct and back liquid pipeline in upper layer are respectively arranged with feed liquor pipe fitting and liquid back pipe connects
Head, the feed liquor pipe fitting and liquid back pipe connector are the helicitic texture for being conveniently replaceable dismounting, the feed liquor pipe fitting and time liquid
Pipe fitting is connected to corresponding input duct and back liquid pipeline sealing respectively.
The two sides of the middle layer plate along, corresponding to being respectively at the feed liquor pipe fitting and liquid back pipe joint location
The outer male structure extended to two sides.
The invention has the advantages that by the logical liquid device being built in putter body, to realize the hydraulic system of hydraulic support
With the piping connection of coal working face hydraulic system, sebific duct realizes the occupancy in pedestrian space between effectively preventing curved frame
Frame is smoothly moved, provides powerful guarantee for creation intrinsically safe mine.Structure of the invention is reliable simultaneously, convenient for disassembly and assembly, adapts to
Property is strong, is especially more suitable for the big thin coal bed fully-mechanized mining hydraulic bracket of working resistance higher to space requirement.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the structural schematic diagram that putter body of the present invention conceals upper layer plate.
Specific embodiment
As shown in Figure 1, 2, the pusher structure of the present invention suitable for full easy opened hydraulic support foundation, including push rod sheet
Body is connected in the connector 1 of putter body front end and the advancing jack hinged seat 2 of rear end；Putter body is folded by upper, middle and lower
The three ply board part 3,4,5 set is constituted；Opened up along longitudinal direction positioned at the upper surface of middle layer plate 4 it is fluted, be equipped in groove into
Liquid pipe road 6 and back liquid pipeline 7；It is located at input duct 6 on upper layer plate 3 and the front and rear ends of back liquid pipeline 7 passes through high pressure
Liquid pipe connection seat 8.1 is connected to the sealing of screwed pipe joint 8.2；Ended by screwed pipe joint 8.2 and feed liquor 6 front end of input duct
Valve 9.2 is connected to, and the front end of back liquid pipeline 7 is connected to by screwed pipe joint 8.2 with liquid cutout valve 9.1 is returned.
By the two sides of middle layer plate 4 along, corresponding to being arranged respectively at 8.1 position of high-pressure liquid tube plinth to two sides
The evagination 10 of extension, 11 structures play push rod Self-resetting of hydraulic support during moving frame and the protection function to Hydraulic Elements
Energy.
In use, by be located at putter body left end feed liquor shut-off valve 9.2, return liquid cutout valve 9.1 respectively with working face
The connection of liquid pump case is returned at face-pumping station, by be located at putter body right end into, return inside liquid screwed pipe joint 8.2 and hydraulic support
Hydraulic system is connected.
