Description
Technical field
This utility model belongs to coal mining support technology field, relates to a kind of gob side entry retaining advanced stand device.
Background technology
Gob-side entry retaining support technology is, during coal-face is mined, to be protected in this work surface (or two) tunnel
Stay, service for subsequent work face.By factors such as geological conditions, recovery method and costs, gob-side entry retaining support technology is not yet
Obtain development in an all-round way, gob side entry retaining advance support more lack maturation Technology, use more waste pack, hydraulic single prop and
Anchor cable carries out advance support, and during the workman's operation of these support patterns, safety is low, and cost is high, and effect is undesirable, narrow application range.
Utility model content
The purpose of this utility model is to provide a kind of gob side entry retaining advanced stand device, and the method can improve workman's operation
Safety.
This utility model be employed technical scheme comprise that, a kind of gob side entry retaining advanced stand device, props up including the first hydraulic pressure
Frame and the second hydraulic support, the first hydraulic support and the second hydraulic support be arranged in parallel, and the first hydraulic support is positioned at gob side entry retaining
Side, tunnel, is provided with multiple wood point post, the first hydraulic support and the second hydraulic pressure between the first hydraulic support and the second hydraulic support
The top of support is provided with wire netting.
Feature of the present utility model also resides in,
Multiple wood point posts are uniformly arranged.
Gap between first hydraulic support and the second hydraulic support is 0.5 ± 0.2m.
The beneficial effects of the utility model are: a kind of gob side entry retaining advanced stand device by arrange the first hydraulic support and
Wood point post, the first hydraulic support and the second hydraulic pressure are set between the second hydraulic support, the first hydraulic support and the second hydraulic support
Cradle top is respectively provided with wire netting, and wood point post forms supporting and shelves cash isolation structure with top metal net, under this structural defence
Carry out the construction of roadside support body.Workman need not enter goaf operation, in the first hydraulic support and the gap of the second hydraulic support
Interior operation, works safer, and after the first hydraulic support and the second hydraulic moving stand, wood point post is made supporting more by roof and floor extruding
Firmly, wood point post low cost, does not reclaims.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of gob side entry retaining advanced stand device；
Fig. 2 is the view of this utility model a kind of gob side entry retaining advanced stand device.
In figure, 1. the first hydraulic support, 2. the second hydraulic support, 3. wood point post, 4. wire netting, 5. roadside support body, 6.
Gob side entry retaining tunnel, 7. goaf.
Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
This utility model provides a kind of gob side entry retaining advanced stand device, as it is shown in figure 1, include the first hydraulic support 1
With the second hydraulic support 2, the first hydraulic support 1 and the second hydraulic support 2 be arranged in parallel, and the first hydraulic support 1 is located along sky and stays
Side, tunnel, lane 6, is provided with multiple wood point post 3, the first hydraulic support 1 and the between the first hydraulic support 1 and the second hydraulic support 2
Top and the front of two hydraulic supports 2 are provided with wire netting 4；
Multiple wood point posts 3 are uniformly arranged；
Gap between first hydraulic support 1 and the second hydraulic support 2 is 0.5 ± 0.2m.
The using method of this utility model a kind of gob side entry retaining advanced stand device is: as in figure 2 it is shown, gob side entry retaining is initial
Position sets 0.5 ± 0.2m gap by staying between side, gob side entry retaining tunnel 6 first hydraulic support 1 and the second hydraulic support 2, and ensures
This gap is kept to be basically unchanged when the most mobile first hydraulic support 1 is with the second hydraulic support 2；Then in gob side entry retaining tunnel 6
First hydraulic support 1 of side and the top of the second hydraulic support 2 and front all lay a grade cash wire netting 4；At the first hydraulic support 1
Wood point post 3 is set in staying, with the second hydraulic support 2, the gap set；Along with the first hydraulic support 1 and the second hydraulic support 2 move forward,
Wood point post 3 forms supporting and shelves cash isolation structure with top metal net 4, carries out executing of roadside support body 5 under this structural defence
Work.
Workman does not enter goaf 7, completes to set wood point post 3 in the first hydraulic support 1 and the second hydraulic support 2 gap,
Working safer, after the first hydraulic support 1 and the reach of the second hydraulic support 2, wood point post 3 is integral with top metal net form,
Side, goaf 7 wire netting naturally droops and lands, and forms gear cash divider wall with wood point post 3, and wood point post 3 is extruded by roof and floor simultaneously,
Advance support is more firm, gives the construction slot milling of roadside support body subsequently and enough intensity.
Wood point post 3 low cost, does not reclaims, solves hydraulic single prop construction loaded down with trivial details, and cost is high, reclaims asking of difficulty
Topic.
This utility model one gob side entry retaining advanced stand device is by arranging the first hydraulic support 1 and the second hydraulic support
2, wood point post 3 is set between first hydraulic support 1 and the second hydraulic support 2, the first hydraulic support 1 and the second hydraulic support 2 push up
Portion is respectively provided with wire netting 4, and wood point post 3 forms supporting and shelves cash isolation structure with top metal net 4, carries out under this structural defence
The construction of roadside support body 5.Workman need not enter goaf 7 operation, in the first hydraulic support 1 and gap of the second hydraulic support 2
Interior operation, works safer, and after the first hydraulic support 1 and the second hydraulic support 2 move frame, wood point post 3 is made supporting by roof and floor extruding
More firm, wood point post 3 low cost, does not reclaims.
