Description
Technical field
The present invention relates to high working face hydraulic support, more particularly, to high working face hydraulic support maintenance platform special.
Background technology
At present, high working face hydraulic support（More than 6 meters of supporting height）Maintenance difficult is carried out during the use of underground, mainly
It is embodied in because hydraulic support height is high, workman is not easy to get at part and valve member when back timber and caving shield are repaired in use；
At present mostly using climbing equipments such as cat ladders, maintenance personal sits on to repair to associated part on back timber and caving shield；This
Outer maintenance personal climbs onto another frame support and overhauled again in the case where being needed after having overhauled a frame support to ground, and this is significantly
Add the difficulty of maintenance work and the potential safety hazard of service worker.
The content of the invention
Present invention aims at provide a kind of high working face hydraulic support maintenance platform special.
To achieve the above object, the present invention takes following technical proposals：
High working face hydraulic support maintenance platform special of the present invention, including be hinged at the top of hydraulic support main body caving shield
Hydraulic jack, piston-rod lower end portion and the maintenance platform of the hydraulic jack are hinged, and the maintenance platform is located at described
On the table top of caving shield side interval be installed with least two linking arms, the linking arm top described at least two respectively with it is described
It is hinged in the middle part of caving shield by otic placode；Edge of the maintenance platform away from caving shield side and longitudinal both sides of the edge have been respectively articulated with
The turnover panel outwards overturn, the turnover panel away from the lateral edges of caving shield one is extended horizontally between two columns of hydraulic support main body.
Longitudinal both sides of the edge of the maintenance platform have set up guardrail respectively.
The table top of the maintenance platform is to be provided with cat ladder on non slip surface, maintenance platform to buckle.
The invention has the advantages that being provided with turnover maintenance platform on caving shield, such a design utilizes high working face hydraulic pressure
Internal stent space is big, there is the characteristics of sufficient space arranges maintenance platform, i.e., do not influence normal mine and there is provided special maintenance
Condition, adjacent height hydraulic support maintenance platform is mutually overlapped to form access path, dimension is provided for maintenance personal by turnover panel
Repair facility.
Brief description of the drawings
Fig. 1 is the structural representation that the present invention is installed on the high working face hydraulic support.
Fig. 2 is the overlooking the structure diagram of the present invention.
Embodiment
Embodiments of the invention are elaborated below in conjunction with the accompanying drawings, the present embodiment using technical solution of the present invention before
Put and implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to down
State embodiment.
As shown in figure 1, high working face hydraulic support maintenance platform special of the present invention, including it is hinged on hydraulic support sheet
The hydraulic jack 2 at the top of body caving shield 1, the bottom of piston rod 3 and the maintenance platform 4 of hydraulic jack 2 are hinged, and maintenance is flat
The table top of platform 4 is non slip surface, and maintenance platform 4 is located at interval on the table top of the side of caving shield 1 and is installed with two linking arms
5.1st, 5.2, the top of two linking arms 5.1,5.2 is hinged with the middle part of caving shield 1 by otic placode 6 respectively；Maintenance platform 4 is remote
The edge of the side of caving shield 1 and longitudinal both sides of the edge are respectively articulated with turned-out turn of turnover panel 7.1,7.2,7.3, away from caving shield
The turnover panel 7.1 of 1 one lateral edges is extended horizontally between two columns 8.1,8.2 of hydraulic support main body；For safety, repair
Longitudinal both sides of the edge of platform 4 and corner have set up guardrail 9.1,9.2 respectively；For ease of the upper and lower maintenance of maintainer
Platform, on maintenance platform being provided with cat ladder buckles.
When the piston rod 3 of jack 2 stretches out, piston rod 3 promotes maintenance platform 4 outwards to overturn；When thousand piston rods 3 are retracted
Shi Ladong maintenance platforms 4 are inwardly overturn；It is so flexible, the change of service clearance between maintenance platform 4 and caving shield 1 is realized, is fitted
Answer maintenance needs during hydraulic support different operating height.Turnover panel 7.2,7.3 rotates around the pin joint of maintenance platform 4, expansion
After snap on adjacent hydraulic support maintenance platform, formed maintenance channel, realize that maintenance personal has overhauled to the hydraulic support
Adjacent hydraulic support is directly arrived after finishing and carries out maintenance work, without repeating to climb.Turnover panel 7.1 surrounds the pin joint of maintenance platform 4
Rotation, is extend into after expansion between two columns 8.1,8.2, and the maintenance in the middle part of hydraulic support top beam is appointed with completing maintenance personal
Business.
