Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1 to Fig. 4, a kind of crawler dozer pressurized cabin that the utility model provides, it comprises the first hermetically-sealed construction 100 and the second hermetically-sealed construction 200.
First hermetically-sealed construction 100, it is specifically arranged on the bottom of driver's cabin, between driver's cabin and floor stand, it increases Elastic Contact on the contact surface at driver's cabin and floor stand, make between driver's cabin and floor stand very close to each other, improve the sealing between driver's cabin and floor stand.
First hermetically-sealed construction 100 comprises sponge 110, U-board 120 and holder 130.
U-board 120, is arranged on cab bottom, and with floor stand close contact, it is for laying sponge 110.
Sponge 110, it is compressed in the side of U-board 120, and it matches and floor stand close contact with U-board 120, and it increases Elastic Contact on the contact surface at driver's cabin and floor stand, improves sealing.
Holder 130, its cross section is boss-shaped, and be fixed in the middle of U-board 120, it is the bulk strength for strengthening U-board 120, and extrudes sponge 110, and sponge 110 is between holder 130 and the side plate of U-board 120.
For the ease of compressing sponge 110, shape before preventing sponge 110 from recovering compression, first hermetically-sealed construction 100 also comprises a L shaped plate 140, L shaped plate 140 is connected with the bottom of holder 130, and assign between sponge 110 and holder 130, such L shaped plate 140 just can contact with sponge 110, extrudes lastingly sponge 110, prevents sponge 110 from recovering.
In order to increase the contact surface between driver's cabin and floor stand further, can all be provided with sponge 110 and L shaped plate 140 in U-board 120 both sides.
Second hermetically-sealed construction 200, it specifically arranges the front lower portion of driver's cabin, and between driver's cabin and instrument box, it increases Elastic Contact on the contact surface at driver's cabin and instrument box, make between driver's cabin and instrument box very close to each other, improve the sealing between driver's cabin and instrument box.
Second hermetically-sealed construction 200 is by sealing rubber strip 210 and junction plate 220.
Sealing rubber strip 210, it is compressed between driver's cabin and instrument box, fits tightly with the side plate 400 of instrument box.
Shape due to sealing rubber strip 210 is unfixed, when pressure between driver's cabin and instrument box is excessive, the volume of sealing rubber strip 210 can diminish, sealing rubber strip 210 is diminished with the contact surface of instrument box side plate 400, thus affect sealing, the shape of sealing rubber strip 210 is set to a U-shaped portion part 211 and annular element 212 two parts by the utility model, and one end and the instrument box of annular element 212 fit tightly, and the other end is fixed on the side of U-shaped portion part 211;
In U-shaped portion part, assigned junction plate 220, junction plate 220 entirety is strip, and it is the shape for fixing seal rubber strip 210, increases the contact surface of sealing rubber strip 210 and instrument box side plate 400.
In order to fixed connecting plate 220, prevent junction plate 220 from sliding, in U-shaped portion part, be provided with latch 213.
The driver's cabin entirety that the utility model provides is spliced by leading flank, trailing flank, left surface, right flank, left front side and right front side.
Left front side and right front side are respectively equipped with the fan door 300 that can open outward, fan door 300 is arranged on left front side and right front side especially by fan door hinge 310, want like this to enter in driver's cabin, the fan door 300 on left front side and right front side all can enter, very convenient.
The fan door 300 of driver's cabin is arranged on the side of driver's cabin by the utility model, facilitates driver to enter like this, also makes between the leading flank of driver's cabin and left surface and right flank very close to each other simultaneously, improves sealing.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
