Abstract
The utility model discloses a telescopic part dustproof structure of a heading machine. The telescopic part dustproof structure of the heading machine comprises a base plate, wherein a support column is fixed below the base plate; one end of the base plate is connected with a first connecting block; a base plate baffle plate with a lead rail is arranged at the other end; the base plate baffle plate is matched with a right baffle plate at the tip of a first sliding plate; a left baffle plate with a lead rail is arranged at the other end of the first sliding plate; a second sliding plate baffle plate matched with the left baffle plate is arranged at one end of the second sliding plate; a second connecting block and a third connecting block are fixed at the other end of the second sliding plate, and a bolt is arranged on the second sliding plate; one end of the telescopic part dustproof structure is connected to a telescopic outer cylinder, and the other end is arranged on a telescopic protecting cylinder. The telescopic part dustproof structure can be telescopically folded, can carry out dust protection when the heading machine achieves certain stroke expansion amount, and can prevent the opposite matched surfaces of the telescopic outer cylinder and the telescopic protecting cylinder from being exposed in an environment with a huge amount of dust and falling coal cinder so as to result in internal dust pollution after a cutting section achieves a certain stroke of expansion.
Description
Technical field
The utility model relates to a kind of operating mechanism of mining machinery, particularly a kind of flexible part of heading machine dustproof construction.
Background technology
In recent years, along with development machine production and use, each manufacturer has accumulated some ripe technology and experiences in the research and development manufacturing of development machine, and the user in use, also proposed the opinions and suggestions of many preciousnesses, each manufacturer updates according to the development machine mode of occupation.
Telescopic structure mainly is comprised of flexible inner core, outer telescopic tube, flexible protection cylinder, cutter head shaft, floating seal frame, floating seal seat etc. in the cutting part of heading machine.Flexible realization mainly is that outer telescopic tube is relative fixing with the connection of cut reductor, and flexible inner core is connected on the flexible protection cylinder with a flexible protection Bolt Connection, telescopic oil cylinder one end fulcrum.When telescopic oil cylinder is flexible, drive the flexible cylinder of protecting and seesaw, thus the integral telescopics such as driving the cutting units front portion is cutterhead and flexible inner core, the protection cylinder that stretches.
Realize the elongation of certain stroke when cutting units after, outer telescopic tube will be exposed in the environment of dust flood tide with the outer cylinder body of flexible protection cylinder relative engagement, the tunnel cinder etc. that can fall simultaneously, and at this moment the outer cylinder body outer wall will be with cinder and a large amount of dust.When cutting units is retracted, the cinder that the outer cylinder body outer wall is entrained or dust will enter pars contractilis inside, through for a long time work, these cinders or dust not only can cause lubricant pollution afterwards, also can damage seal, the bearing of cutting units inside, the coating of fitting face etc. for a long time.
The utility model content
The technical problems to be solved in the utility model can cause the pars contractilis internal contamination when being cutting part of heading machine work, and a kind of flexible part of heading machine dustproof construction that prevents that cutting part of heading machine from polluting is provided.
The technical solution of the utility model realizes in the following manner: a kind of flexible part of heading machine dustproof construction, comprise substrate, the substrate below is fixed with support column, substrate one end links to each other with the first coupling block, the other end is provided with the substrate baffle plate with guide rail, the substrate baffle plate cooperates with the right baffle plate of the first sliding panel termination, the other end of the first sliding panel is provided with the right baffle-plate with guide rail, the second sliding panel one end is provided with the second sliding panel baffle plate that cooperates with right baffle-plate, the second sliding panel other end is fixed with the second coupling block and the 3rd coupling block, and the second sliding panel is provided with bolt.
Described substrate is that bolt connects with being connected coupling block.
The utility model one end is connected on the outer telescopic tube; the other end is installed on the flexible protection cylinder; the utility model telescopic folding; can when realizing certain stroke stroke, development machine carry out the dust protection; prevent after cutting units is realized the elongation of certain stroke; outer telescopic tube and flexible protection cylinder relative engagement face be exposed to the dust flood tide and the environment that falls with cinder in, cause inner dust pollution.

The specific embodiment
As depicted in figs. 1 and 2, a kind of flexible part of heading machine dustproof construction, comprise substrate 1, substrate 1 below is fixed with support column 7, substrate 1 one ends link to each other with the first coupling block 4, the other end is provided with the substrate baffle plate 1-1 with guide rail, substrate baffle plate 1-1 cooperates with the right baffle plate 2-1 of the first sliding panel 2 terminations, the other end of the first sliding panel 2 is provided with the right baffle-plate 2-2 with guide rail, the second sliding panel 3 one ends are provided with the second sliding panel baffle plate 3-1 that cooperates with right baffle-plate 2-2, the second sliding panel 3 other ends are fixed with the second coupling block 5 and the 3rd coupling block 6, the second sliding panels 3 are provided with bolt 8.
Described substrate 1 is that bolt connects with being connected coupling block 4.
In the utility model, right baffle plate 2-1 on the first sliding panel 2 can slide along the guide rail on the substrate baffle plate 1-1, the second sliding panel baffle plate 3-1 on the second sliding panel 3 can slide along the guide rail on the right baffle-plate 2-2, and each baffle plate can limit the telescopic slide amount, prevents from disconnecting.
As shown in Figure 3, the utility model use procedure is as follows: the first coupling block 4 is weldingly connected with outer telescopic tube 10, and the second coupling block 5 and the 3rd coupling block 6 are welded on the flexible protection cylinder 11.When cutting part of heading machine stretches out, relative fixing with the substrate 1 of outer telescopic tube 10 connections, protect flexible the doing relative motion of cylinder 11 along with stretching with flexible protection cylinder 11 the second sliding panels 3 that are connected and the first sliding panel 2.Wherein flexible inner core 12 is connected with flexible protection cylinder 11 bolts.
The utility model is not limited to above-described embodiment; be to be understood that those skilled in the art can carry out to the parts that relate in above-described embodiment the suitable new embodiment that is combined to form, the various obvious modifications and variations of carrying out on the basis that does not break away from the utility model principle all should fall within the protection domain of the present utility model.
