Abstract
The utility model discloses a kind of special frame for withdrawal; the model includes a substrate of larger area, a connecting rod group connected to the seat, a covering beam and top beam connected to the connecting rod group, and the standing column between the seat and the top beam; the substrate includes a substrate frame, a push rod which is set on the substrate and can extend along the vertical direction of the substrate frame, a fuel tank of push-pull rod set at the end of the substrate frame, a plurality of pulleys set on the substrate frame; at the end of the push-pull rod is set the push head; the connecting rod group includes the front and back connecting rods directly connected to the seat; the front and back connecting rods are connected to the covering beam through the pin; the top beam includes the beam body, the hydraulic cylinder fixed in the beam and the tensile front beam; the standing column includes the hydraulic cylinder and the extended column. When the frame is transported along the space provided by the special frame for withdrawal through the frame carrier, the exposed top plate of the removed frame can be effectively supported.
Description
Technical field
The utility model relates to a kind of time and removes special stand, particularly, relates in particular to a kind of fully-mechanized mining working removal of home special hydraulic support of falling the face.
Background technology
In the coal in China industry, since fully-mechanized mining working adopted hydraulic support stand, safety improved greatly.In the concrete process of implementing, after a work plane has been adopted, withdraw from these supports, and the place of withdrawing from support plays the wooden supporting of piling up neatly, this way is promptly dangerous, and efficient is not high again, can not satisfy the modernization coal mining requirement of high-yield and high-efficiency.
Particularly, after fully-mechanized mining working was mined end, the capital equipment that fully-mechanized mining working surface hydraulic support is carried was a bracket carrier.But, because carrier appearance and size is big, support itself is bulky in addition, so support is returning when removing carrying, need bigger rack restoring space, this just needs an interim support apparatus, replaces fully-mechanized mining working surface hydraulic support, also provides a safe and reliable working space for the staff reaches back the equipment of removing simultaneously.
Therefore, be necessary to design a kind of new returning in fact and remove special stand, to satisfy above-mentioned technical requirements.
The utility model content
The purpose of this utility model be to provide a kind of can be when support be withdrawn for evacuate district's top board provide effective support be convenient to move return and remove special stand.
To achieve these goals, removing special stand for of the present utility model time is design like this:
Remove special stand a kind of time, it comprises having than the large tracts of land pedestal, the connection rod set that is connected with base, the caving shield that is connected with described connection rod set, the back timber that is connected with this caving shield and be connected base and back timber between column, described pedestal comprises a frame substrate, be located on this frame substrate can be along the flexible pull bar of frame substrate longitudinally, be located at the pull bar oil cylinder of frame substrate end, be installed in the some pulleys on the described frame substrate, the end of described pull bar is provided with the passing head, described connection rod set comprises front rod and the back link that directly links to each other with pedestal, before being somebody's turn to do, back link is connected by bearing pin with caving shield, described back timber comprises cross girder, be fixed in the cross girder hydraulic cylinder and under the effect of this hydraulic cylinder relatively cross girder carry out the cantilever extension of stretching motion, described column comprises hydraulic cylinder and by the driven back timber lifting of Driven by Hydraulic Cylinder and the extending column of decline.
The utility model compared with prior art has the following advantages: when support by bracket carrier when returning the space transportation remove that special stand provides, the top board that support exposed of moving can be by effective support, ensure the safety of rack restoring personnel and equipment, reduce labor strength, save mine timber.
Description of drawings
Fig. 1 removes the front view of special stand of the present utility model time;
Fig. 2 removes the vertical view of special stand of the present utility model time.
The specific embodiment
See also Fig. 1, remove for of the present utility model time special stand 1 comprise the connection rod set 4 that has larger area pedestal 2, is connected, the caving shield 6 that is connected with described connection rod set 4, the back timber 8 that is connected with this caving shield 6 with base 2 and be connected base 2 and back timber 8 between column 9.
Wherein, described pedestal 2 contacts with ground, tunnel and as returning the basic supporting surface remove special stand 1, and described connection rod set 4 mainly plays a part to be connected and to screen with caving shield 6, and the supporting role of back timber 8 by column 9 provides supporting for the top board in tunnel.
Please further combined with consulting Fig. 2, described pedestal 2 comprises a frame substrate 20, be located on this frame substrate 20 can be along the flexible pull bar 22 of frame substrate 20 longitudinallies, be located at the pull bar oil cylinder 28 of frame substrate 20 ends, the side limited block 26 that is installed in some pulleys 24 of pull bar 22 both sides on the described frame substrate 20 and is fixedly installed on frame substrate 20 sides, the end of described pull bar 22 is provided with passes 220.
Described connection rod set 4 comprises front rod 40 and the back link 42 that directly links to each other with pedestal 2, this front and rear connecting rods 40,42 and caving shield 6 are connected by bearing pin, thereby make and can relatively rotate in the folding mode of mutual work between caving shield 6 and the front and rear connecting rods 40,42.
Described back timber 8 comprises cross girder 80, be fixed on hydraulic cylinder 82 on the cross girder 80, cross girder 80 side guard board 86 that carries out the cantilever extension 84 of stretching motion, extended vertically downward by cross girder 80 both sides relatively under the effect of this hydraulic cylinder 82.
Described column 9 comprises hydraulic cylinder 90 and the extending column 92 that is driven by hydraulic cylinder 90, and the stretching motion of this extending column 92 can drive back timber 8 liftings and decline, cooperates the folding movement between caving shield 6 and the front and rear connecting rods 40,42 simultaneously.
When the reality use is removed special stand 1 of the present utility model time, at first use locomotive to return to remove special stand 1 and be transported to the working site, use winch to act on pulley 24 then and drag it to accurate position by hawser, the primer fluid cylinder pressure 90 then, make extending column 92 that back timber 8 is raised to back, at this moment, caving shield 6 relative front and rear connecting rods 40,42 rotate; At last, determine the extension elongation of cantilever extension 84 according to concrete operating mode.
The utility model compared with prior art has the following advantages: when support passes through a shelf for conveying Car is during along the space transportation that withdraws that special stand provides, and the top board that the support of moving exposes can With by effective support, ensure the safety of rack restoring personnel and equipment, reduce labor strength, Save mine timber.
