Description
Technical field
The utility model relates to a kind of coal mining articles for use, particularly a kind of hydraulic shield support.
Background technology
In the coal production process of coal-face, in order to prevent roof collapse, maintain certain working space, ensure that safety of workers and work in every normally carry out, supporting must be carried out to top board, and hydraulic support is the equipment of supporting and the controlroof be made up of Hydraulic Elements and hardware using highly pressurised liquid as power, it can realize support, cuts top, move a whole set of operation such as frame and moving conveyor.The hydraulic prop that we use now is all that two hydraulic column support degrees are inadequate, or have four hydraulic columns but its shielding platform can not adjust its length, very flexible safety is lower, also not easily moves in the process of moving simultaneously.
Utility model content
The utility model, mainly for above problem, provides the advantages such as a kind of supporting performance is good, intensity is high, advancing velocity is fast, safe and reliable.Hydraulic support can with curved conveyor and coal-winning machine combined machine coal excavation apparatus, its application is to increasing coal-face output, raising labour productivity, reduce costs, alleviate workman's work and ensure the shield support of safety in production, and its technical scheme is as follows:
A kind of hydraulic shield support comprises: base, hydraulic column one, hydraulic column two, support column, shielding platform one, shielding platform two and shielding platform three, described pan frontward end is fixedly connected with hydraulic column one, base rear end is fixedly connected with hydraulic column two, base end is connected with support column by being hinged, described support column is connected with shielding platform one by the mode be hinged, shielding platform one is rotationally connected with shielding platform two, described shielding platform two is rotationally connected with shielding platform three, described support column is stretching structure, when hydraulic column one and hydraulic column two do stretching, support column support shield platform one is elevated, described shielding platform three is stretching structure, bottom surface is installed hydraulic stem and is promoted the flexible of shielding platform three.
On technique scheme basis, jack is installed in described base end face corner, and base end face both sides are provided with sliding-rail groove, installs folding universal wheel inside base end face corner.
On technique scheme basis, described hydraulic column one and hydraulic column two quantity are all two, and support column is divided into two parts support column one and support column two.
The retractility of the utility model shielding platform increases protection in the space of transverse direction; so just need not the movement of shifter shielding platform entire machine specially; enhance productivity, four hydraulic props make that its supporting performance is good, intensity is high, universal wheel and slide rail add advantages such as making its overall advancing velocity fast, safe and reliable.Hydraulic support can with curved conveyor and coal-winning machine combined machine coal excavation apparatus, its application to increase coal-face output, raise labour productivity, reduce costs, alleviate workman's work and ensure safety in production.

Fig. 1 is the utility model structural representation;
Symbol description:
1. base, 2. hydraulic column one, 3. hydraulic column two, 4. support column, 5. shielding platform one, 6. shielding platform two, 7. shielding platform three.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, a kind of hydraulic shield support comprises: base 1, hydraulic column 1, hydraulic column 1, support column 4, shielding platform 1, shielding platform 26 and shielding platform 37, described base 1 front end is fixedly connected with hydraulic column 1, base 1 rear end is fixedly connected with hydraulic column 23, base 1 end is connected with support column 4 by being hinged, described support column 4 is connected with shielding platform 1 by the mode be hinged, shielding platform 1 is rotationally connected with shielding platform 26, described shielding platform 26 is rotationally connected with shielding platform 37, described support column 4 is stretching structure, when hydraulic column 1 and hydraulic column 23 do stretching, support column support shield platform 1 is elevated, described shielding platform 37 is stretching structure, bottom surface is installed hydraulic stem and is promoted the flexible of shielding platform 37, in use described, if when top shielding platform falls short of, we can adjust the length of its three sections of shielding platforms, we temporary needs may change place in the process used simultaneously, we are the jack stand equipment by corner, put down universal wheel to promote, or dynamic track can be laid, slide into place to use.
Preferably, jack is installed in corner, described base 1 bottom surface, and base end face both sides are provided with sliding-rail groove, installs folding universal wheel inside base end face corner.
Preferably, described hydraulic column 1 and hydraulic column 23 quantity are all two, and support column 4 is divided into two parts support column one and support column two.
The retractility of the utility model shielding platform increases protection in the space of transverse direction; so just need not the movement of shifter shielding platform entire machine specially; enhance productivity, four hydraulic props make that its supporting performance is good, intensity is high, universal wheel and slide rail add advantages such as making its overall advancing velocity fast, safe and reliable.Hydraulic support can with curved conveyor and coal-winning machine combined machine coal excavation apparatus, its application to increase coal work output, raise labour productivity, reduce costs, alleviate workman's work and ensure safety in production.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
