The sealing housing is characterized in that a cover plate is provided with an elongated groove, vertical plates are mounted at two ends of the upper surface of the cover plate, and two slideways are arranged on the upper end face between the two vertical plates of the cover plate; two sealing covers are mounted above the cover plate on a slideway support, each sealing cover is composed of a top plate and three side walls, and the lower ends of the two side walls of the two sealing covers are nested into the slideways of the cover plate; the top plates of the sealing covers are provided with elongated notches, springs are fixedly mounted between the vertical plates and the sealing covers, and the cover plate of the slideway support is provided with through holes. Compared with the prior art, the sealing housing has the advantages of simple structure and novel design.
Description
Technical field
The utility model relates to a kind of sealing arrangement, is particularly a kind ofly applicable to the seal closure that opposite house machine walking coarst brake seals.
Background technology
At present, on-the-spot at door machine operation, owing to there being the foreign material such as a large amount of dusts, ore in sand form, and and easily by enter machine walking coarst brake brake strap, each bearing pin hinge etc. of wind, located, thereby can cause this position corrosion, clamping stagnation, lubricant effect is bad, so that door machine walking coarst brake opens and closes not smooth.And there is no at present effective method, ore in sand form, dust and other impurities and door machine coarst brake are effectively isolated and guaranteed that coarst brake switching is smooth and easy, flexible, effective simultaneously.
Utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, and a kind of seal closure that opposite house machine walking coarst brake seals that is applicable to is provided.
The technical scheme in the invention for solving the technical problem is: a kind of machine walking coarst brake seal closure, is characterized in that: comprise slideway support and seal closure, described slideway support comprises cover plate and riser, on described cover plate, has long slot bore; Described cover plate upper surface two ends are provided with riser, and between described cover plate two risers, the upper surface of part is provided with two slideways; The top of the cover plate of described slideway support is provided with two seal closures, and described seal closure is comprised of top board and three sidewalls, and the lower end of the two side of two described seal closures is embedded in the slideway of cover plate; The top board of described seal closure is provided with strip shape breach; Between described riser and seal closure, be installed with spring; The cover plate of described slideway support is provided with through hole.
The lower end of above-mentioned seal closure two side is provided with pulley.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, this device has solved door machine coarst brake brake strap pivot pin clamping stagnation, has got rusty, opened and closed the phenomenons such as not smooth, has guaranteed again that coarst brake opens and closes simultaneously smooth and easy, flexible, effective;
2, this device is fixedly connected with a fixed orifice for door machine coarst brake base by bolt, convenient disassembly, is easy to install.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of seal closure in Fig. 1.
The specific embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, the utility model comprises slideway support 7 and seal closure 4.
Described slideway support 7 comprises cover plate 1 and riser 2.On described cover plate 1, have long slot bore, the curved bar 5 of door machine walking coarst brake is through described long slot bore, and long slot bore can not limit the stroke activity of curved bar 5.
Described cover plate 1 upper surface two ends are provided with riser 2, and between described 1 liang of riser of cover plate, the upper surface of part is provided with two slideways.
The top of the cover plate 1 of described slideway support 7 is provided with two seal closures 4 of relatively arranging, and described seal closure 4 is comprised of top board and three sidewalls, and the lower end of the two side of two described seal closures 4 is embedded in the slideway of cover plate 1.In prioritization scheme, as shown in Figure 2, the lower end of described seal closure 4 two sides is provided with pulley 10, can make like this seal closure 4 more easily slide in the slideway of cover plate 1.The top board of described seal closure 4 is provided with strip shape breach, and the through hole that the curved bar 5 of door machine walking coarst brake forms through the strip shape breach on two seal closures 4 is connected with pedal brake plate 6.The long slot bore position of described cover plate 1 does not exceed the top board travel range of two seal closures 4, and namely seal closure 4 covers on long slot bore all the time.
Between described riser 2 and seal closure 4, be installed with spring 8.The cover plate 1 of described slideway support 7 is provided with through hole, and described slideway support 7 is fixedly connected with door machine coarst brake base by bolt 9.
Operating process is as follows: the slideway support 7 of this device is fixed together by bolt 9 and door machine coarst brake base.Make two seal closures 4 cover on a place, the gap that machine coarst brake is exposed, when stepping on pedal brake plate 6, curved bar 5 moves, when curved bar 5 touches seal closure 4, two seal closure 4 also start to move along slideway, due to the effect of spring 8, two seal closures 4 are close contact relatively all the time, and can not expose gap.After unclamping pedal brake plate 6, due to the effect of spring 8, when the curved bar 5 of door machine coarst brake recovers position, seal closure 4 returns to original position equally equally.In whole process, the gap of door machine coarst brake can not be exposed in working environment, thereby does not have dust, the foreign material such as ore in sand form are located by the enter brake strap, each bearing pin hinge etc. of machine walking coarst brake of wind.Can solve like this machine coarst brake brake strap pivot pin clamping stagnation, get rusty, open and close the phenomenons such as not smooth, can guarantee that again coarst brake opens and closes smooth and easy, flexible, effective.
It should be noted that; particular of the present utility model have been described in detail the utility model; for a person skilled in the art, the various apparent change of in the situation that not deviating from spirit and scope of the present utility model, it being carried out is all within protection domain of the present utility model.
