Abstract
The utility model discloses a big stride support that slides of taking a step has solved the problem that current device stride is little, intensity of labour is big, its characterized in that the auxiliary girder on set up guide bar, balladeur train fixing base, set up balladeur train, big balladeur train on the girder, the other end of balladeur train is established on the guide bar, big balladeur train includes and takes a step two semi -ring uide bushings of jack complex that big balladeur train is fixed on the excircle of jack of taking a step through two halves ring uide bushing, taking a step, the balladeur train is connected to the front end of jack, the balladeur train fixing base is connected to the rear end, the balladeur train slides on the guide bar. The utility model discloses only with a guide bar, be aided with the excircle direction of the jack of taking a step again, under the condition that does not increase back timber length, increase the stride of the support that slides, need not to improve that the timberer hinders, structural strength, back timber length and sectional area, stand cylinder diameter etc. Reduce support input, equipment is light and handy, and more convenient operation for the high space of girdle working face saving, improves production efficiency etc. By a wide margin.
Description
Technical field
The utility model relates to a kind of support apparatus in coal mine, relates to one or rather and to take a step slippage bracket.
Background technology
Slippage bracket of taking a step is the common equipment of underground coal mine supporting, and conventional design is between girder, auxiliary girder, be provided with former and later two guide pegs, a jack of taking a step, and the front and back end of jack of taking a step, respectively on two guide pegs, two guide pegs is moved.Due to this structural restriction, each step pitch of taking a step has certain limitation: first, due to the restriction of supporting power and stability etc., major and minor beam can not be long, former and later two guide pegs add that the length of the jack of taking a step in middle part just has larger limitation, so just limit take a step distance and the step pitch of slippage bracket, limit cutting of coal-winning machine dark, particularly in the good situation of roof and floor condition, production efficiency does not increase.Secondly, the operation of taking a step of scrapper conveyor passing and slippage bracket, become relatively frequent, and operate the labour all wanting at substantial each time, labour intensity is strengthened, safety in production burden, production efficiency is subject to certain impact.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art provides a kind of large step pitch to take a step slippage bracket, when not increasing major-minor beam length and namely not increasing support control top load, strengthens the step pitch of slippage bracket.
The utility model comprises girder, auxiliary girder, guide peg, jack of taking a step, and it is characterized in that: described auxiliary girder is arranged guide peg, balladeur train holder, and girder arranges balladeur train, large balladeur train, and the other end of balladeur train is established on the guide bar; Large balladeur train comprises two the semi-ring fairleads coordinated with jack of taking a step, and large balladeur train is fixed on by two semi-ring fairleads takes a step on the cylindrical of jack; Take a step jack front end connects balladeur train, rear end connects balladeur train holder; Balladeur train slides on the guide bar.
The utility model adds a jack of taking a step two of traditional design guide pegs, change into only with a guide peg, be aided with the cylindrical guiding of jack of taking a step again, the length of major and minor like this beam is only distributed by a guide peg and a jack, can when not increasing major and minor beam length, the length of jack and guide peg of taking a step can significantly increase, thus the step pitch of slippage bracket is also significantly increased.
Technique scheme is known, the utility model, through Transform Type design, when not increasing back timber (i.e. major-minor beam) length and the distance of face roof under control, strengthens the step pitch of slippage bracket, such as, the work plane of former section of dark 600mm rises to and cuts dark 1000mm, without the need to improving timberer's resistance, structural strength, back timber length and sectional area, column cylinder diameter etc., reducing support and dropping into, equipment is light and handy, more convenient operation, for thin seam working surface saves height space, significantly enhances productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is application schematic diagram of the present utility model.
In figure, 1. girder, 2. auxiliary girder, 3. guide peg, 4. balladeur train, jack of 5. taking a step, 6. large balladeur train, 7. balladeur train holder, 61. semi-ring fairleads;
8. coal-winning machine, 9. scrapper conveyor, 10. girder front column, 11. auxiliary girder front columns, 12. girder rear columns, 13. auxiliary girder rear columns.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises girder 1, auxiliary girder 2, guide peg 3, balladeur train 4, take a step jack 5, balladeur train holder 7 etc.Auxiliary girder 2 arranges guide peg 3, balladeur train holder 7, girder 1 arranges balladeur train 4, large balladeur train 6, the other end of balladeur train 4 is located on guide peg 3, large balladeur train 6 comprises two the semi-ring fairleads 61 coordinated with jack 5 of taking a step, and large balladeur train 6 is screwed in by two semi-ring fairleads 61 takes a step on the cylindrical of jack 5; Taking a step, jack 5 front end connects balladeur train 4, rear end connects balladeur train holder 7, and balladeur train 4 slides on guide peg 3.
Figure 2 shows that the schematic diagram that coal-winning machine 8, scrapper conveyor 9 are supporting with the utility model.When slippage bracket of taking a step needs mobile, under auxiliary girder 2 is in holding state (adjacent frame is also in holding state), after the unloading of girder front column 10 below girder 1, girder rear column 12, to jack 5 feed flow of taking a step, take a step jack 5 outer shell using the bearing on auxiliary girder 2 as the strong point, piston rod promotes girder 1 and moves ahead to rib, and at this moment balladeur train 4 and large balladeur train 6 slide along the cylinder barrel cylindrical of guide peg 3 and jack 5 of taking a step to rib direction respectively, lead to girder 1.After girder 1 puts in place, prop the girder front column 10 below it, girder rear column 12, make girder 1 be in holding state.Then the front and back column below auxiliary girder 2 and auxiliary girder front column 11, auxiliary girder rear column 13 are unloaded, to jack 5 oppositely feed flow of taking a step, with the bearing on girder 1 for the strong point, auxiliary girder 2 is pulled to move forward, at this moment the cylinder barrel of balladeur train 4 and large balladeur train 6 relative guide peg 3 and jack 5 of taking a step respectively does counter motion, leads to auxiliary girder 2.After auxiliary girder 2 is in place, props the auxiliary girder front column 11 of auxiliary girder 2, auxiliary girder rear column 13, once taking a step of support can be completed.
