Abstract
The utility model discloses a kind of hydraulic support top beam retinue side protecting mechanism, comprise set cap, be arranged on the extensible canopy of set cap front end, be articulated with the wall supporting of extensible canopy front end by quadric chain; Wall supporting jack and extensible canopy jack are disposed side by side on the middle part of extensible canopy respectively, and end and the quadric chain of wall supporting jack piston rod are hinged, and are hinged in the middle part of its cylinder body and extensible canopy rear end; Piston rod end and the extensible canopy of extensible canopy jack are hinged, and its cylinder body and set cap front center are hinged.The utility model advantage is the middle part described wall supporting jack, extensible canopy jack being arranged on described extensible canopy, eliminate the conventional supporting plate in traditional side protecting mechanism, thus make the thickness of set cap front end be able to suitable reduction, like this, the gap of hydraulic support and supporting scratch board conveyor increases, and hydraulic support strengthens the compliance of thin seam working surface.Meanwhile, wall supporting jack and extensible canopy are hinged, and achieve the retinue of wall supporting and extensible canopy.
Description
Technical field
The utility model relates to that mining height is lower, the hydraulic support top beam of three machine supporting space anxieties in coal wall, especially relates to hydraulic support top beam retinue side protecting mechanism.
Background technology
In the coal wall of mechanical mining, need by digger, drag conveyor, hydraulic support reasonable Arrangement, reasonable distribution space to make each parts normally run time non-interference, to work in coordination again work simultaneously, so just can make whole exploitation work plane high-yield and high-efficiency.Due to exploitation work plane complex geologic conditions, colliery layer thickness constantly changes, and can only realize efficient by adjustment hydraulic support mining height guarantee mineral products purity height like this.After hydraulic support mining height reduces, the three above-mentioned supporting spaces of machine are nervous, and the normal operation of the whole work plane of mechanical interference effect may occur three machines.For Design of Powered Supports, need, under guarantee support intensity degree prerequisite, to reduce back timber nose thickness as far as possible.
Summary of the invention
The utility model object is to provide a kind of hydraulic support top beam retinue side protecting mechanism, to reduce hydraulic support nose thickness.
For achieving the above object, the utility model adopts following technical proposals:
Hydraulic support top beam retinue side protecting mechanism described in the utility model, is comprised set cap, is arranged on the extensible canopy of described set cap front end, be articulated with the wall supporting of described extensible canopy front end by quadric chain; Wall supporting jack and extensible canopy jack are disposed side by side on the middle part of extensible canopy respectively, and end and the described quadric chain of described wall supporting jack piston rod are hinged, and are hinged in the middle part of its cylinder body and extensible canopy rear end; Piston rod end and the extensible canopy of described extensible canopy jack are hinged, and its cylinder body and set cap front center are hinged.
This uses novel advantage to be described wall supporting jack, extensible canopy jack to be arranged on the middle part of described extensible canopy, eliminate the conventional supporting plate in traditional side protecting mechanism, thus make the thickness of set cap front end be able to suitable reduction, like this, the gap of hydraulic support and supporting scratch board conveyor increases, and hydraulic support strengthens the compliance of thin seam working surface.Meanwhile, wall supporting jack and extensible canopy are hinged, and achieve the retinue of wall supporting and extensible canopy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, hydraulic support top beam retinue side protecting mechanism described in the utility model, is comprised set cap 1, is plugged in the extensible canopy 2 of described set cap 1 front end, be articulated with the wall supporting 4 of described extensible canopy 2 front end by quadric chain 3; Wall supporting jack 5 and extensible canopy jack 6 are disposed side by side on the middle part of extensible canopy 2 respectively, and end and the described quadric chain 3 of described wall supporting jack piston rod 7 are hinged, and are hinged in the middle part of its cylinder body and extensible canopy 2 rear end; Piston rod end and the extensible canopy 2 of described extensible canopy jack 6 are hinged, and its cylinder body and set cap 1 front center are hinged.
