Abstract
The utility model provides a kind of coal mining driving protective device, including pedestal, and the pedestal both upper ends thereof is respectively equipped with foundation, foundation upper end connection liquid cylinder pressure, hydraulic cylinder upper end is equipped with hydraulic stem and elastic plate, and hydraulic stem upper end is equipped with top plate, and hydraulic stem passes through elastic plate and connect with mandril.The utility model structure is simple, easy to use, is used by the adjusting of elastic plate and hydraulic cylinder, and the sustainable passway formed when tunneling of mining prevents that accident occurs in coal mining tunneling process, protects production safety.
Description
Technical field
The utility model relates to safety of coal mines engineering, specially a kind of coal mining driving protective device.
Background technique
Coal mining technology, no matter outdoor or underground, on the basis of the high mechanization having reached at present, just towards life
Remote control, the automation direction development, design, type selecting, material, manufacturing process, inspection party by improving fully-mechanized mining equipment of production process
Method and maintenance will improve its production capacity and utilization rate of equipment and installations, while also guarantee production safety.Safety of coal mines thing at present
Therefore it is multiple, good mechanical equipment can be effectively improved production operation environment, and protection is mined, and driving is safe to carry out.
Utility model content
The main purpose of the utility model is to be to provide a kind of coal mining driving protective device, during protecting fully mechanized mining
Safety.
To achieve the above object, the utility model is achieved by the following technical programs: a kind of coal mining driving protection
Device, including pedestal, it is characterised in that: pedestal both upper ends thereof is respectively equipped with foundation, foundation upper end connection liquid cylinder pressure, on hydraulic cylinder
End is equipped with hydraulic stem and elastic plate, and hydraulic stem upper end is equipped with top plate, and hydraulic stem passes through elastic plate and connect with mandril.
Preferred: the elastic plate material is 60Si2Mn spring steel, and number is solid with fixing sleeve between multiple and elastic plate
It is fixed.
Preferred: the elasticity board ends are curly and volume is set in shaft, and hydraulic stem bottom and hydraulic cylinder contact position
It is equipped with cavity, the both ends of elastic plate are placed in cavity and connect by shaft with cavity wall.
Compared with prior art, the utility model has the following beneficial effects: the protective device structure letter of this coal mining driving
Single, easy to install and use, top plate is contacted with elastic plate and hydraulic stem, controller perturbation of the hydraulic stem by hydraulic cylinder, by upper
Tenesmus caused by top plate can be effectively buffered when the landslide or shaking that just happen suddenly, production channel security in protection lower section passes through.Bullet
Property plate due to distinctive material and arc structure, can the larger pressure for reducing hydraulic cylinder by top plate, guarantee production safety.

Fig. 2 is the hydraulic stem internal cavity structural schematic diagram in Fig. 1.
Fig. 3 is elastic plate and hydraulic stem connection schematic diagram in Fig. 1.
In figure: 1, pedestal；2, foundation；3, hydraulic cylinder；4, elastic plate；5, top plate；6, hydraulic stem.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
A kind of coal mining driving protective device, as shown in Figure 1, including pedestal 1,1 both upper ends thereof of pedestal is respectively equipped with foundation
2,2 upper end connection liquid cylinder pressure 3 of foundation, 3 upper end of hydraulic cylinder is equipped with hydraulic stem 6 and elastic plate 4, and 6 upper end of hydraulic stem is equipped with top plate 5,
Hydraulic stem 6 passes through elastic plate 4 and connect with top plate 5.
4 material of elastic plate is 60Si2Mn spring steel, and multiple elastic plates 4 are combined with fixing sleeve and connected.
4 both ends of elastic plate are curly and volume is set in shaft, and 6 bottom of hydraulic stem is equipped with cavity, and the both ends of elastic plate 4 are set
It is connect in cavity and by shaft with cavity wall.
Pedestal 1 is fixed on ground, for hydraulic stem 6 by 3 telescopic adjustment of hydraulic cylinder, when installation stretches out hydraulic stem 6, makes elasticity
Plate 4 withstands top plate 5 and makes the contact of top plate 5 top stratum, and elastic plate 4 stops elongation hydraulic stem 6 when deformation occurs, elastic at this time
Plate 4 is in elastic stage.When this device works, pressure of the top plate 5 by top stratum, due to elastic plate 4, hydraulic stem 6 and top
Plate 5 contacts, pressure of the elastic plate 4 by top plate 5, and elastic plate 4 is arc-shaped curved surface structure, and material is 60Si2Mn spring steel, can incite somebody to action
Most of power snubber is converted into interior energy, and hydraulic stem 6 can be delayed latch plate 4 and top plate 5 due to the presence of hydraulic cylinder 3
Punching effect, the safety of effective protection fully mechanized mining under certain condition.Pedestal 1 is fixed on ground simultaneously, prevents pedestal 1 during the work time
Displacement is generated, is device hair into inclination.
The utility model structure is simple, easy to install and use, is used by the adjusting of elastic plate and hydraulic cylinder, sustainable to adopt
The channel that coal is formed when tunneling, prevents that accident occurs in coal mining tunneling process, protects production safety.
