Abstract
The invention provides a coal mine supporting device, which comprises a hydraulic prop; the hydraulic prop bottom rigid coupling has the bottom plate, and the bottom plate passes through set screw to be fixed on the muddy soil square on ground, the upper end movable mounting of hydraulic prop has the crossbeam, and the side fixed mounting of hydraulic prop has the fixed cover of side direction. The support column is fixed on the ground and the wall surface, so that the shaking effect of the support column is reduced, the support strength which can be borne by the support column is increased, and the support column can timely know when the pressure changes through the detection and monitoring of the pressure value, and timely process and prevent collapse.
Description
Technical Field
The invention relates to a coal mine supporting device.
Background
The mining of coal mines usually needs to be carried out at the bottom of the ground, and support needs to be carried out in a excavated rural road during the mining process, but due to the fact that the crust moves constantly or the influence on the terrain during the mining process, the supporting surface in a roadway collapses.
Disclosure of Invention
In order to solve the technical problem, the invention provides a coal mine supporting device.
The invention is realized by the following technical scheme.
The invention provides a coal mine supporting device, which comprises a hydraulic prop; the hydraulic prop bottom rigid coupling has the bottom plate, and the bottom plate passes through set screw to be fixed on the muddy soil square on ground, the upper end movable mounting of hydraulic prop has the crossbeam, and the side fixed mounting of hydraulic prop has the fixed cover of side direction.
The cross beam is arranged on the hydraulic prop through a movable sleeve, and the movable sleeve and the hydraulic prop are locked through a bolt.
And the cross beams are all provided with a plurality of cross beams.
And the top of the extending end of the hydraulic support is provided with a top plate.
The lateral fixing sleeve is fixed on the movable sleeve, the two sides of the lateral fixing sleeve are fixedly connected with a lug with a through hole, the lug is fixedly provided with a tensioning screw through a screw cap on the side surface of the lug, and the tensioning screw is embedded in the wall of the mine.
And a pressure sensor is arranged in a hydraulic cavity of the hydraulic column and is connected with the controller through a wireless signal transmission device.
And a plurality of reinforcing ribs are fixedly connected between the bottom plate and the hydraulic prop.
The invention has the beneficial effects that: through fixing the support column on ground and wall, reduce its effect of rocking, also the increase of the support dynamics that it can bear to through the detection and the control of pressure value, can in time know when making its pressure change, in time handle and prevent to collapse the emergence.

FIG. 1 is a schematic structural view of the present invention;
In the figure: 1-hydraulic prop, 2-concrete earthwork, 3-reinforcing rib, 4-fixed screw, 5-bottom plate, 6-movable sleeve, 7-top plate, 8-lateral fixed sleeve, 9-tensioning screw, 10-hydraulic column and 11-beam.
Detailed Description
the technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
A coal mine supporting device comprises a hydraulic prop 1; the bottom of the hydraulic support column 1 is fixedly connected with a bottom plate 5, the bottom plate 5 is fixed on a soil mixing square 2 on the ground through a fixing screw rod 4, a cross beam 11 is movably mounted at the upper end of the hydraulic support column 1, and a lateral fixing sleeve 8 is fixedly mounted on the side face of the hydraulic support column 1.
The cross beam 11 is arranged on the hydraulic prop 1 through a movable sleeve 6, and the movable sleeve 6 and the hydraulic prop 1 are locked through bolts.
And a plurality of cross beams 11 are arranged on the cross beams 11.
And a top plate 7 is arranged at the top of the extending end of the hydraulic prop 1.
The lateral fixing sleeve 8 is fixed on the movable sleeve 6, the two sides of the lateral fixing sleeve 8 are fixedly connected with lugs provided with through holes, the lugs are fixedly provided with tensioning screws 9 through nuts on the side faces of the lugs, and the tensioning screws 9 are buried on the wall of a mine.
And a pressure sensor is arranged in a hydraulic cavity of the hydraulic column 10 and is connected with the controller through a wireless signal transmission device. The pressure value in the hydraulic cavity when the support is finished is preset in the controller, the detection value of the pressure sensor transmitted by the wireless signal transmission device is received at any time, and when the detection value is far larger than the preset value, the controller sends an alarm signal to a worker.
And a plurality of reinforcing ribs 3 are fixedly connected between the bottom plate 5 and the hydraulic prop 1.
