Description
Technical field
The present invention relates to a kind of coal-mine hydraulic support, particularly a kind of hydraulic support with digging function.
Background technology
CN1987046A discloses a kind of continuous digging machine with support frame, and it can tunnel continuously in the supporting direction.But its application is the driving in tunnel, is very different with the exploitation in colliery in the work plane, and its move mode and supporting intensity all can't satisfy the needs that work plane is mined.And it mainly is that development machine is improved, basis at development machine has increased between the supporting, and the structure of development machine is complicated, and cost of production is relatively high, as carrying out work plane coal mining with it, in the situation that the extensive cost of production that will inevitably increase coal that uses.
CN1103926A discloses a kind of hydraulic support with the digging function, and it arranges excavation machinery at hydraulic support, finishes the exploitation of working face of coal seam.But it forwardly arranges is planing tool, and its operating efficiency and pick strength are lower, can only be applied to preferably colliery of coal seam conditions, and can't promote on a large scale.
CN201068798Y discloses a kind of down-hole coal excavation apparatus, and the front end of its support is provided with coal-winning machine.But its coal-winning machine is connected on the drag conveyor, rather than is connected on the support, and therefore, it can't excavate when moving frame, and it also can't adjust the attitude of coal-winning machine flexibly.
Summary of the invention
The objective of the invention is to propose a kind of hydraulic support with digging function, its front portion at hydraulic support has high-intensity extractive equipment, the coal seam that can adapt to various situations to finish the work in the frame exploitation in face colliery of reach, has been improved production efficiency at support greatly.Simultaneously, this hydraulic support simple in structure, installation and maintenance are convenient, and are cheap, can obtain through transformation on the basis of existing hydraulic support, are very suitable for the application in the coal mining.
The present invention obtains by following method.
A kind of hydraulic support with digging function comprises base, back timber, it is characterized in that described hydraulic support also comprises coal-cutting drum, and described coal-cutting drum is directly connected on the base of described hydraulic support by linkage.
Described coal-cutting drum has hydraulic motor, and described hydraulic motor is controlled by reversal valve.
Described linkage is jack.
Described jack comprises elastic jack, heightens jack and support jack up and down, by described elastic jack, the described spatial attitude of heightening up and down the cooperation adjusting coal-cutting drum of jack and described support jack.
Described elastic jack, describedly heighten up and down jack and described support jack is controlled by reversal valve.
The invention has the advantages that:
Can realize that many supports mine simultaneously, greatly improve coal mining efficient;
The everything of this hydraulic support all by reversal valve control, makes control system more succinct;
This hydraulic support is mined and the process of supporting mainly relies on hydraulic coupling to realize, different from normal fully-mechanized mining working is high voltage source and the corollary equipment thereof that does not need special coal-winning machine and power is provided to coal-winning machine, has simplified the complexity of work plane system;
By the spatial attitude of heightening up and down jack, support jack, elastic jack control coal-cutting drum, controllability is good, can satisfy the needs of multiple different coal situation;
Cylinder and support are combined as a whole, and are convenient to maintenance and malfunction elimination.
Description of drawings
Fig. 1 is the structural representation of coal mining support
Among the figure, the 1-coal-cutting drum, the 2-hydraulic motor, the elastic jack of 3-, 4-support jack, 5-are heightened up and down jack, 6-base, 7-back timber.
The specific embodiment
As shown in Figure 1, a kind of hydraulic support with digging function, comprise base, back timber and coal-cutting drum, described coal-cutting drum is directly connected on the base of described hydraulic support by linkage, so-called directly namely other does not have the parts of other function such as conveying device etc. in the middle of it, and described coal-cutting drum has the hydraulic motor by reversal valve control, above-mentioned hydraulic motor preferably independently but also can be in the situation that allow to share with the miscellaneous equipment of coal mining support.
Described linkage can be any link commonly used that satisfies the bonding strength requirement.One preferred embodiment in, described linkage is jack.Described jack comprises elastic jack, heightens jack and support jack up and down, described elastic jack connects the hydraulic motor of coal-cutting drum, by the position adjustments on the flexible realization coal-cutting drum fore-and-aft direction of jack, describedly heighten up and down the end that jack is hinged on elastic jack, by the position adjustments on the flexible realization coal-cutting drum above-below direction of jack, described support jack is hinged on the middle part of elastic jack, the fulcrum that moves up and down as coal-cutting drum.Each jack is controlled by reversal valve separately.
For a person skilled in the art, be understandable that, as long as elastic jack realizes that the up-down adjustment of jack realization coal-cutting drum is regulated, heightened up and down in the front and back of coal-cutting drum, support jack realizes that the configuration mode of support function all allows, above-mentioned configuration mode only illustrates.
Be understandable that equally, described linkage also can adopt other different configuration mode, and is by this jack that cylinder is direct-connected to the base of hydraulic support as a jack only is set, as long as configuration mode can make the coal-cutting drum normal operation.
A preferred course of work of the hydraulic support in the technical program is as follows:
For every hydraulic support, at first, hydraulic support enters the operating position of work plane, the beginning supporting, bracket support is finished back roll and is started working, the cutting coal seam, the conveyer that coal under the cutting falls into the below transports out, in the process of cutting, can regulate at any time the attitude that each jack comes index drum, guarantee optimum cutting efficiency.When needs moved frame, the cylinder cutting action was closed and is guaranteed to move smoothly frame by regulating elastic jack, support jack and heightening up and down jack adjusting cylinder position, after hydraulic support enters new operating position, directly carries out supporting and gets final product.Repeat above-mentioned supporting cutting process.On whole work plane, a plurality of above-mentioned hydraulic supports can compose in parallel a support group.In actual applications, can be according to actual conditions by regulating in order successively cutting of each support in each support control reversal valve (not shown) realization group, also can the realization group in a plurality of supports cut simultaneously, until finish the mining work of full face.。
The above; only be the better specific embodiment of patent of the present invention; but the protection domain of patent of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that patent of the present invention discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of patent of the present invention.
