Description
Technical field
The present invention relates to thick seam slicing system technical field, more particularly to a kind of bottom plate of thick seam slicing system are automatic
Spread interconnection device and method.
Background technology
Largely abundant coal resources are contained central and west regions in China, and part ocurrence of coal seam thickness reaches 20m, studies this
The production technique of class super high seam, sustainable development to coal resources in China and increases economic efficiency and has extremely important war
Slightly meaning.
Mainly there is high working face once to adopt complete thick fully mechanized mining coal-mining method, mining for the current recovery method of super high seam
Method and separate zone production method.Under the conditions of existing technical equipment, separate zone production is typically used when coal seam thickness is more than 10m
With two methods of top coal caving, its foundation selected depends primarily on the putting property in coal seam.But top coal caving causes coal
The significant wastage of charcoal resource, in order to improve the recovery ratio of coal resources, increasing super high seam uses the skill of separate zone production
Art, and realized by being layered lapping and be caving the separation in spoil and coal seam.However, the laying for Hierarchical Network in recovery process at present
Need to be accomplished manually mostly, its labor intensity is big, and networking efficiency is low, and personal security cannot guarantee that.
The Chinese patent of Application No. 85108109 discloses a kind of thick seam slicing system Man-made False lapping, networking side
Method and device, are particularly suitable for comprehensive mechanical coal mining.Lapping frame and networking frame be set at automatic shifting stand rear portion, one on lapping frame
Individual movable pulley bypasses a haulage cable, and the rope is fixed on automatic shifting stand base, and lapping frame and connection are driven by booster is moved
Rack moves forward, and realizes automatic lapping.The shortcomings that this method is：1st, it is every to working face in working face mining, bottom plate laid process
One support is both needed to set up net volume and arranges network unit, and larger to the support reformation dynamics, equipment cost is higher；2nd, due to each
Hydraulic support is respectively provided with net volume and network unit, therefore requires that several underground labours are individually managed to lapping, networking, and it is worked
Intensity is big, and efficiency is low, and multiple network unit cooperations, and accident rate is high；3rd, the network unit of the invention is mainly to gold
Category net is networked, but the long term physical performance of wire netting can not fully ensure that, especially under conditions of the complexity of underground, more hold
Perishable destruction, and wire netting carrying is extremely inconvenient, labor strength is very high, and colliery thick seam slicing system more makes at present
With plastic wire or polyester fiber net, it is therefore necessary to design a kind of new network unit to adapt to current thick seam slicing system
Networking requirement.
The Chinese patent of Application No. 92230281.2 discloses a kind of suitable for underground coal mine super high seam working face
Sub-Level Caving or lapping hydraulic bracket.The support quadric chain is arranged in the medium position of hydraulic support, the cant beam of double leval jib and
Lower link is arranged between front two rows column, and the distance between the width of cant beam and two lateral surfaces of lower link are more than left and right two
The distance between column inner side is arranged, maximum is close to the width in hydraulic support.It is antitorque strong the invention provides larger transverse direction
Degree and lapping space, but it is not directed to spread the structure and its technique of interconnection device, it can not realize that underground spreads networking automatically.
The content of the invention
The present invention mainly solve problems of the prior art, there is provided one kind can realize automatically spread network, equipment into
The bottom plate of the thick seam slicing system of this low, great operability and practicality spreads interconnection device and method automatically.
The high seam of the present invention refers to that thickness is more than 3.5m coal seam.
To reach above-mentioned purpose, the present invention adopts the technical scheme that：
A kind of bottom plate of thick seam slicing system spreads interconnection device automatically, includes multiple hydraulic pressure branch of parallel getting working face
Frame, the afterbody of each hydraulic support are provided with a back seat；Be respectively equipped with the back seat net volume laying mechanism, slipping mechanism and
Network unit；The net volume laying mechanism is used to installing or sprawling the net volume wound；The slipping mechanism is arranged on net volume paving

Structure is fixed on slipping mechanism, and the overlap joint overlapping part for treating lapping volume and lapping is rolled up carries out suture and connected.
Further, the net volume laying mechanism include the first net cylinder wheel hub, the second net cylinder wheel hub, net cylinder, hub arm and
Networking column, the networking column and hub arm are separately fixed at the both sides of slipping mechanism, the first net cylinder wheel hub and second
Net cylinder wheel hub is separately mounted to network in column and hub arm, and the position of the first net cylinder wheel hub and the position of the second net cylinder wheel hub
Corresponding, the net cylinder is arranged between the first net cylinder wheel hub and the second net cylinder wheel hub, and the surface wrap of the net cylinder has net volume.
Further, the slipping mechanism includes guide rail, guide rail wheel and the mobile mainboard of networking, and compartment of terrain is set on the back seat
There are two parallel grooves, guide rail is fixed on the bottom of groove, and guide rail is parallel with getting working face, and the guide rail wheel is arranged on
The lower surface both sides of the mobile mainboard of networking, it is corresponding with the guide rail position, 3~5 are arranged per side, and be in rolling contact with guide rail,
The hub arm and networking column are accordingly fixed on the upper surface both sides of the mobile mainboard of networking.
Further, the network unit includes networking arm, upper stitching unstrument, networking rifle pin, support pit and lower suture
Device；One end of the networking arm is fixed on the top of networking column, and the other end lower surface for arm of networking is fixed with suture
Device, upper stitching unstrument are connected with networking rifle pin, and networking rifle pin is provided with the first networking line；After the afterbody of back seat is provided with support
Groove, described lower stitching unstrument is connected with the mobile mainboard lower surface of networking, vertical corresponding with upper stitching unstrument, can be transported in back seat groove
OK, the second networking line is additionally provided with lower stitching unstrument, when upper stitching unstrument drives networking rifle pin back and forth to move down, the first networking line passes through
After lapping volume and lapping volume overlap joint overlapping part mesh after with second network line phase fit.
Further, the width of the mobile mainboard of networking three times of gap length or so between the hydraulic support,
To ensure that it can be smoothly across the space between the hydraulic support.
The bottom plate of thick seam slicing system provided by the invention spreads networking method automatically.
The first step, the net volume wound is installed on net volume laying mechanism, specifically included：
Net volume is wrapped in the surface of net cylinder, and the first net cylinder wheel hub and the second net cylinder on net volume laying mechanism
