Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
According to illustrated in figures 1 and 2, the utility model provides a kind of locking structure of traverse platform of engineering machinery, wherein; This locking structure comprises traverse platform 1 and gets off 2, and traverse platform 1 is installed in pivotally gets off on 2 so that the revolution attitude of getting on the bus is regulated, and traverse platform 1 is respectively arranged with the stop pin 3 and locking aperture 4 that can plug cooperation with getting off on 2; Thereby the plug through stop pin 3 and locking aperture 4 cooperates the locking that realizes traverse platform, wherein, and in the utility model; Locking structure also comprises piston cylinder 5; This piston cylinder 5 comprises cylinder barrel, piston rod 52, rodless cavity 51 and rod chamber 53, wherein, is provided with elastic component 6 in the rodless cavity 51; Piston rod 52 is connected with stop pin 3, have on the cylinder barrel be communicated with rod chamber 53 go into head piece 54.
Therefore, in technique scheme, when stop pin 3 need be extracted in locking aperture 4,54 pairs of rod chambers of head piece, the 53 supply pressure fluids of going into through piston cylinder 5 shrank piston rod 52 get final product, and simultaneously elastic component 6 are compressed.And when needs are inserted into locking aperture 4 with stop pin 3, then again the fluid in the rod chamber 53 is discharged through going into head piece 54, and can piston rod be released through the elastic restoring force effect of elastic component 6, carry out insertion work thereby drive stop pin 3.
What need stress is, because stop pin 3 is when inserting, stop pin 3 and locking aperture 4 be complete matching not; And this moment; Through the ingenious design of the utility model, stop pin 3 can be pressed under the effect of elastic force on the circular traces of justifying together with locking aperture 4, and moves on this circular trace with the revolution of traverse platform 1; When stop pin 3 with after locking aperture 4 overlaps, stop pin 3 falls into locking aperture 4 automatically.Because the elastic force of elastic component 6 is much smaller than the power that hydraulic pressure or air pressure produced, and has buffering, therefore can not damage stop pin 3 or other associated components.Therefore the utility model is compared the plug of using oil hydraulic cylinder or pneumatic cylinder driven locking pin fully and is had more practical operation value under the situation that does not need manual operation, and Security is higher.
In addition; Can accomplish the utility model purpose mode of execution has multiple; The set-up mode of stop pin 3 and locking aperture 4 for example, the kind of piston cylinder 5 etc., the preferred implementation of the utility model is only introduced in explanation for ease; This preferred implementation only is used to explain the utility model, is not limited to the utility model.
In a preferred embodiment; Piston cylinder 5 can adopt single-action hydraulic cylinder common in related domain; Its piston rod 52 is resetted by spring usually, so the elastic component in the utility model 6 is preferably the spring in this single-action hydraulic cylinder, goes into 54 of head pieces and is the filler opening of hydraulic oil.Certainly, known in those skilled in the art other can satisfy the piston cylinder of the utility model purpose, and for example pneumatic linear actuator etc. all is applicable to the utility model.
As shown in Figure 1; Get off 2 tops and be convenient to install the associated components of the utility model because traverse platform 1 is arranged in; Preferably, traverse platform 1 is provided with fixedly otic placode 11, and piston cylinder 5 is fixed on the fixedly top of otic placode 11; Stop pin 3 passes fixedly otic placode 11 and matches with locking aperture 4, and this locking aperture 4 is formed on gets off on 2.Wherein need to prove; In this mode of execution; What those skilled in the art can expect is; Can in the rodless cavity 51 of piston cylinder 5, elastic component 6 be set, and fall automatically, so this set form also should fall in the protection domain of the utility model through the gravity of piston rod 52 and stop pin 3.
Convenient for locking aperture 3 is formed, preferably, getting off 2 is provided with fixed base 21, and locking aperture 4 is formed on the fixed base 21, and wherein fixed base 21 can be welded on and get off on 2, perhaps gets off on 2 through dismountable being installed in of fastening pieces such as screw.In addition, for the ease of in the latch process, stop pin 3 can slide in the locking aperture 4 of fixed base 21, and preferably, the surface of this fixed base 21 is a streamlined structure, and with the 1 streamlined transition of getting off.Therefore, owing to there are not sharp-pointed corner angle, stop pin 3 can slide in the locking aperture 4 smoothly.
In addition, in order to improve the utility model, preferably, locking structure also comprises and is used to detect stop pin 3 position Detection devices 7.More preferably, this detection device 7 is near switch, can detected groove 31 near switch and be formed with this on the stop pin 3.In actual use, can this, can more directly control traverse platform 1 and turn round through the displacement detecting to this groove 31 near switch 7, perhaps provides various feedback signals, makes operator can learn the position relation of stop pin 3 and locking aperture 4.Wherein, In the time of in stop pin 3 is inserted into locking aperture 4, can controls traverse platform near switch and can not turn round, the beacon of perhaps controlling in the operator cabin is opened; Or it accomplishes the feedback system that other those skilled in the art can expect; Therefore, the driver can not or can not carry out the revolution operation of traverse platform 1, to avoid parts damages such as stop pins.Make the practicability and the Security of the utility model higher.
Therefore, the locking structure of the traverse platform that provides of the utility model has strong practicability and promotional value.
According to the utility model on the other hand, a kind of hoist is provided, this hoist comprises the locking structure of the traverse platform of the engineering machinery that the utility model provides.
One side again according to the utility model provides a kind of engineering machinery, and this project machinery comprises the locking structure of the traverse platform of the engineering machinery that the utility model provides.
Therefore, through using the locking structure of the traverse platform that the utility model provides, make that the locking of traverse platform of this hoist or engineering machinery is more easy to control, practicability is higher.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned mode of execution; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technological scheme of the utility model, these simple variant all belong to the protection domain of the utility model.
Need to prove in addition; Each concrete technical characteristics described in above-mentioned embodiment under reconcilable situation, can make up through any suitable manner; For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.
In addition, also can carry out combination in any between the various mode of execution of the utility model, as long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model equally.
