For achieving the above object; the remote de-locking device of air spring protecting jacket of the present utility model; comprise flexible axle, flexible shaft bracket and draw-off mechanism; described flexible axle comprises axle core and is set in the axle core sheath outside axle core; described axle core applies pulling force by described draw-off mechanism to described air spring protecting jacket; described axle core sheath is connected with described flexible shaft bracket, and described flexible shaft bracket is fixedly connected on described air spring protecting jacket.
Preferably; on described air spring protecting jacket, be provided with mounting bracket; described mounting bracket comprises the body that is fixed on air spring protecting jacket and the contiguous block hinged with described body; on described contiguous block, be provided with the backing pin that can act on described air spring protecting jacket, and the afterbody of described contiguous block is connected with described axle core.
Preferably, on the axle core between described contiguous block and described flexible shaft bracket, be set with Returnning spring.
Preferably, described flexible shaft bracket and described mounting bracket are structure as a whole.
Preferably, described draw-off mechanism is handle.
The remote de-locking device of air spring protecting jacket of the present utility model, axle core sheath is connected with flexible shaft bracket, and flexible shaft bracket is fixed on protecting jacket, and axle core sheath is limited on air spring protecting jacket.When axle core being applied to pulling force by draw-off mechanism, with very little steering force, just can complete the release of air spring.And axle core sheath and air spring protecting jacket together move, avoid the wearing and tearing between axle core and axle core sheath, extended the working life of flexible axle.Meanwhile, Returnning spring can make axle core reset in time after air spring release.
Accompanying drawing explanation
Fig. 1 is the structural representation of the remote de-locking device of the utility model air spring protecting jacket;
Fig. 2 is the partial enlarged drawing of A part in Fig. 1.
Embodiment
As shown in Fig. 1～2; the remote de-locking device of air spring protecting jacket of the present utility model; comprise flexible axle 2, flexible shaft bracket 1 and draw-off mechanism; flexible axle 2 comprises axle core 21 and is set in the axle core sheath 22 outside axle core 21; axle core 21 applies pulling force by draw-off mechanism to air spring protecting jacket 5; shaft core sheath 22 is all extended at Zhou Xin21 two ends; its one end directly or be indirectly connected on air spring protecting jacket 5 by other links; the other end is connected with draw-off mechanism, to can produce active force to air spring protecting jacket 5.Axle core sheath 22 is connected with flexible shaft bracket 1, and flexible shaft bracket 1 is fixedly connected on air spring protecting jacket 5.Certainly, this axle core sheath 22 two ends can be connected with aforementioned flexible shaft bracket 1 for such structure ，Ji one end, and the other end is connected with the frame of machinery to be installed, to can further limit the position of axle core sheath.When pulling axle core 21 by draw-off mechanism, axle core 21 can pull air spring protecting jacket 5 to make it produce displacement, to can release reset.In pulling axle core 21 processes, axle core 21 does not produce wearing and tearing substantially with axle core sheath 22.
Axle core 21 can be directly connected on air spring protecting jacket 5, for convenience of axle core 21, pulls air spring protecting jacket 5, and in the utility model, axle core 21 is installed on air spring protecting jacket 5 indirectly by mounting bracket 4.On air spring protecting jacket 5, be provided with mounting bracket 4, mounting bracket 4 is positioned at the top of flexible shaft bracket 1.Mounting bracket 4 comprises the body 41 that is fixed on air spring protecting jacket 5 and the contiguous block 42 hinged with body 41, be provided with the backing pin 45 that can act on air spring protecting jacket 5, and the afterbody of contiguous block 42 is connected on contiguous block 42 with axle core 21.As shown in the figure, body 41 is fixed on air spring protecting jacket 5 by U bolt 43, and locking bolt 44 forms the hinging shaft of body 41 and contiguous block 42, and body 41 can rotate with respect to locking bolt 44 with contiguous block 42.Contiguous block 42 is roughly inverted L shaped, it comprise Zhong Yige end, ，Liang Ge end, He Yige bight, Liang Ge end and body 41 hinged, another end, with kink, has hole on kink, so that axle core 21 passes, and by screw, axle core 21 is fixing, backing pin 45 is arranged on bight.Backing pin 45 is mainly used for when draw-off mechanism pulls axle core 21 promoting air spring protecting jacket 5, and therefore, it should be arranged on a side relative with axle core 21.
In the utility model, mounting bracket 4 is structure as a whole with flexible shaft bracket 1, and the afterbody bending of mounting bracket body 41, forms flexible shaft bracket 1.Flexible axle 2 can insert in flexible shaft bracket 1, and flexible shaft bracket 1 is spacing for flexible axle 2 is carried out along its length, to prevent that flexible axle 2 is because deadweight departs from air spring protecting jacket 5.Certainly, mounting bracket 4 also can be processed respectively with flexible shaft bracket 1, and mounting bracket 4 plays the effect that auxiliary axis core 21 pulls air spring protecting jacket 5, and flexible shaft bracket 1 plays flexible axle 2 is carried out to spacing effect.
In the utility model, draw-off mechanism is handle 3.Certainly, it also can be realized by other means, as by setting up other mechanical devices such as pulley, and by electronic control, realizes the automatic pull of axle core 21 and controls.
In order to facilitate axle core 21 can reset in time, on the axle core 21 between contiguous block 42 and flexible shaft bracket 1, be set with Returnning spring 6 after 5 releases of air spring protecting jacket.When 5 releases of air spring protecting jacket and draw-off mechanism do not apply active force to axle core 21, axle core 21 can reset in time.While especially using handle 3, after release, under the effect of Returnning spring 6, handle 3 can automatically reset.
During use, by draw-off mechanism, pull axle core 21, axle core 21 drives air spring protecting jacket 5 to move, and air spring protecting jacket 5 is staggered with respect to the piston rod of air spring, and air spring piston bar is regained, and realizes the release of air spring protecting jacket 5.During release; because axle core sheath 22 is connected on air spring protecting jacket 5, axle core sheath 22 can together move along with air spring protecting jacket 5, therefore; axle core 21 can not produce deflection substantially with axle core sheath 22, thereby has prevented the wearing and tearing between axle core 21 and axle core sheath 22.
The remote de-locking device of the air spring protecting jacket in the utility model can the air spring for roller cover piece on, and other common air spring use occasions.As shown in Figure 1, air spring is arranged on vehicle frame 7, and flexible axle sheath 22 one end are installed on air spring protecting jacket 5 by flexible shaft bracket 1, and the other end is installed on vehicle frame 7 by connection bracket 8.Axle Xin21 one end is connected with mounting bracket 4, to air spring protecting jacket 5 is applied to pulling force, the other end is connected with handle 3.When applying pulling force by 3 pairs of axle cores 21 of handle, axle core 21 pulls contiguous block 42 afterbodys of mounting bracket 4, and contiguous block 42 rotates relative to locking bolt 44,45 pairs of air spring protecting jacket 5 applied thrusts of backing pin, thereby 5 releases of air spring protecting jacket.
