The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of escalator device, and it is arranged on getting on the bus of engineering machinery.
Refer to Fig. 1 to Fig. 3, this escalator device of the embodiment of the present invention comprises access door 1, ladder 2 and access door stopping means.
This access door 1 is articulated with getting on the bus on 9 of this project machinery, and this access door 1 and this are got on the bus and between 9, be formed with pin joint 8.Maintainer can overhaul this access door 1 to the inner member of engineering machinery after center of rotation is opened take this pin joint 8, this access door 1 can be used as inspection platform after opening simultaneously, base oneself upon part for maintainer provides, therefore can avoid causing maintainer to turn round because of stopping of access door and the phenomenon of inconvenient walking on walking on stage.The both sides of this access door 1 are provided with relative limiting plate 11, on each limiting plate 11, offer chute 12.
This ladder 2 comprises body 21 and is fixed on the axle 22 of these body 21 both sides, each axle 22 is mounted slidably in corresponding chute 12, and therefore, this ladder 2 relatively this access door 1 slides, that is to say, this ladder 2 can be arranged to push-and-pull a side of this access door 1.The length of this ladder 2 is slightly shorter than the length of this chute 12, like this, gets on the bus in 9 when promote can to make when these ladders 2 have reclaimed this ladder 2 this access door 1 completely this ladder 2 to be hidden at this to this pin joint 8.Preferably; this limiting plate 11 is arranged at the inner side of this access door 1; this access door 1 is towards a side of engineering machinery inner member; in the time that access door 1 is closed; this ladder 2 can be protected at this and get on the bus in 9; preventing that this ladder 2 from leaking cruelly in this gets on the bus outside 9 and is subject to wind and weather and the damage of getting rusty, and can improve the application life of this ladder 2.In the time that access door 1 is opened, this ladder 2 can be pulled out along the direction of this chute 12 from a side of this access door 1, in the time that this axle 22 supports the least significant end at this chute 12, direction is earthward rotated this ladder 2 again, make to be formed with angle β between this ladder 2 and this access door 1, this angle β can be obtuse angle or right angle.Wherein, the angle of this angle β is preferably obtuse angle, and like this, the maintainer that is more convenient for climbs this ladder 2.
This access door stopping means is arranged at this and gets on the bus on 9, and this access door stopping means is for limiting the angle that this access door 1 is opened, and prevents that angle that this access door 1 overturns is excessive and causes maintainer cannot stand on this access door 1.Preferably, this access door stopping means can be limited in the angle paralleling with horizontal plane by this access door 1, while making maintainer stand on this access door 1, is unlikely to slip or throw.
Refer to Fig. 4, the first embodiment of this access door stopping means is support 31, and this support 31 is fixed on this below of getting on the bus on 9 and being positioned at this pin joint 8.This support 31 can support this access door 1, and maintainer can be stood on this access door 1.This support 31 can be rectangle, triangle etc.Because triangle has advantages of higher stability compared to rectangle, so the shape of this support 31 is preferably triangle, and take right-angled triangle as best.The right-angle side that is shaped as the support 31 of right-angled triangle is fixed on this and gets on the bus on 9, and another right-angle side upward.In the time that this access door 1 turns to the angle paralleling with horizontal plane, the outside of this access door 1 supports on this support 31, by this support 31, this access door 1 is supported.
Please again consult Fig. 1 to Fig. 3, the second embodiment of this access door stopping means is that damper 32 and one end are connected on this damper 32, the other end is connected to the rope 33 on this access door 1.This damper 32 comprises that cylinder barrel and telescopically are arranged at the expansion link in this cylinder barrel.This cylinder barrel is fixed on this and gets on the bus on 9, and the end of this expansion link is connected with this rope 33.This damper 32 can be air damper, can be also liquid condenser.Due to air damper have compressibilty large, bear that displacement is large, viscosity is with advantages such as temperature inversion are little, therefore, the damper 32 of the embodiment of the present invention is preferably air damper.The viscosity that this damper 32 has by self, can reduce the speed that this access door 1 is opened, and avoids this access door 1 and this shock of getting on the bus between 9, the application life of improving this access door 1.As shown in Figures 2 and 3, when this expansion link bounces back in this cylinder barrel completely, the state of this access door 1 in paralleling with horizontal plane, now this rope 33 pulls this access door 1 to make it keep stable state, avoids maintainer to drop from this access door 1; As shown in Figure 1, this expansion link is in the time that maximum is stretched out stroke, and this rope 33 pulls this access door 1 in closed condition.
Escalator device provided by the present invention, owing to adopting access door to base oneself upon part as inspection platform for maintainer provides, therefore can avoid causing maintainer to turn round on walking on stage because of stopping of access door and the phenomenon of inconvenient walking.In addition; this escalator device can hide the inside in engineering machinery by this ladder in the time that access door is closed; not only can protect ladder; nor must this escalator device be removed from engineering machinery because of the restriction of highway transportation limit for width, therefore can improve transition and the efficiency of construction of engineering machinery.
A kind of engineering machinery with above-mentioned escalator device that the present invention also provides.Because above-mentioned escalator device has above-mentioned technique effect, therefore, the engineering machinery that is provided with this escalator device also should possess corresponding technique effect, and its specific implementation process is similar to the above embodiments, therefore do not repeat.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
