Technical field
The present invention relates to the hydraulic support in a kind of colliery, particularly relate to a kind of extremely soft seam hydraulic support.
Background technology
At present, having a large amount of extremely soft seam in many places, ature of coal hardness f is only about 1, and coal bed joints is grown, and belongs to and is difficult to working seam, and these collieries can only adopt artificial coal mining now, and coal-mining method is as follows:
Work surface support or the supporting such as monomer or stringer, adopt scrapper conveyor transport, and rib and old man adopt plank or bamboo raft etc. to seal, dig a hole at the nearly top board place of rib, choker block lath, then remove and seal lath, coal is caving outflow, piecemeal or compartment put coal, transport with scrapper conveyor.
Coal-mining method of the prior art, it is impossible to realize mechanical mining, efficiency is low, poor stability.
Summary of the invention
It is an object of the invention to provide a kind of safe efficient operation extremely soft seam hydraulic support that can realize extremely soft seam work surface.
It is an object of the invention to be achieved through the following technical solutions:
The extremely soft seam hydraulic support of the present invention, including back timber, the front portion of described back timber is provided with extensible canopy, it is characterized in that, the front end of described extensible canopy arranges lengthening beam, and the rear portion of this support is provided with and bottoms out sealing device, and the front end of lengthening beam described in work process is inserted in rib.
As seen from the above technical solution provided by the invention, the extremely soft seam hydraulic support that the embodiment of the present invention provides, owing to the front end of extensible canopy arranges lengthening beam, the rear portion of support is provided with and bottoms out sealing device, in work process, the front end of lengthening beam is inserted in rib, the strength utilizing bracket jack realizes rib built-in inserted plate and supports, and old man side tail beam flashboard realizes fully sealing, it is possible to achieve the safe efficient operation of extremely soft seam work surface.

Detailed description of the invention
The embodiment of the present invention will be described in further detail below.
The extremely soft seam hydraulic support of the present invention, its preferably detailed description of the invention be:
Including back timber, the front portion of described back timber is provided with extensible canopy, and the front end of described extensible canopy arranges lengthening beam, and the rear portion of this support is provided with and bottoms out sealing device, and the front end of lengthening beam described in work process is inserted in rib.
It is provided with bolt between described lengthening beam and extensible canopy, is additionally provided with the stress key and keyway that match.
The described sealing device that bottoms out includes tail boom, and described tail boom is provided with movable side protection plate and flashboard mechanism, and described flashboard mechanism stretches out under maximum rating its lower end lower than the bottom surface of this support.
The base of this support is provided with thrust gear, and described thrust gear includes pusher rod, and the bottom of described pusher rod is provided with two and sweeps device, respectively before sweep device and after sweep device, be respectively arranged on the front and rear of described pusher rod.
This support is two post hydraulic supports, is provided with two balance jack etc. between back timber and the caving shield of described two post hydraulic supports.
This support is four post hydraulic supports.
This support is provided with reverse-four-link-bar structure.
The afterbody of this support adopts balance arm to bottom out sealing device as described.
The afterbody of this support adopts the structure that back link adds waste rock board to bottom out sealing device as described.
The invention solves when using ordinary stent in extremely soft seam, beam front top plate and coal wall caving, be caving uncontrollable, old man's bastard coal etc. pours between frame, the problem such as in frame.Existing coal-mining method is carried out mechanization and automatization, the strength utilizing bracket jack realizes rib built-in inserted plate and supports, and coal-winning machine is coaling, and quickly propels, old man side tail beam flashboard realizes fully sealing, and realizes the safe efficient operation of extremely soft seam work surface with this.
Principles of the invention is:
As it is shown in figure 5, be deep in rib by set cap front support point depths, take measures to strengthen stent cusps support force, reduce rib pressure, control rib and be caving thickness；
Because being extremely soft seam, the spontaneous caving of coal is utilized to mine, then with the loading of coal-winning machine；
Sealing of old man direction adopts the form of tail beam flashboard to insert end sealing；
Pusher rod is swept device for coal and is prevented long-pending coal.
Specific embodiment:
As shown in Figure 1, Figure 2 shown in a, Fig. 2 b, the front portion of back timber is provided with extensible canopy, and the front end of extensible canopy arranges lengthening beam, steel plate installed-welded form, and size is determined according to corollary equipment.
As it is shown on figure 3, lengthening beam and extensible canopy adopt Bolt to position, the fixed form of keyway stress, lengthening beam is controlled to stretch receipts by telescopic jack with extensible canopy.
For ensureing enough lengthening beam tip support power, except enough working resistances, the balance adjustment power much larger than general support is set, as adopted two large-diameter balance jack etc..
As it is shown in figure 1, support afterbody arranges the tail beam flashboard mechanism of similar sublevel caving hydrau lic support, tail boom and back timber, caving shield are the same, arrange movable side protection plate, and tail beam flashboard mechanism can realize bottoming out sealing preferably, and can form the plant maintenance safe space of necessity.
As shown in Figure 4, because ature of coal is soft, it is easy to amass under pusher rod, causing operation inconvenience, therefore pusher rod is provided with pusher rod and sweeps device for coal.
Protection scope of the present invention is embodiment on being not limited to, it is also possible to be specific examples below:
The four post hydraulic supports with lengthening beam and tail sealing device；
Hydraulic support with sealing devices such as lengthening beam structure, reverse-four-link-bar, afterbody employing balance arms；
Back link is adopted to add the hydraulic support of sealing device of waste rock board with lengthening beam structure, afterbody；
Hydraulic support with other versions or lengthening beam in fixed form.
The above; being only the present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, any those familiar with the art is in the technical scope of present disclosure; the change that can readily occur in or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
