Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
Fig. 1 is wheel crane operation vibration-proof equipment 10 block diagram provided by the invention, and as shown in Figure 1, this equipment 10 comprises receiving device 101 and control setup 102.Wheel crane is when operation, the supporting leg of these wheel crane both sides stretches out and hoists to prop this wheel crane, receiving device 101 is for receiving the vertical distance between the vehicle frame of wheel crane and vehicle bridge, control setup 102 is for performing following at least one: what control to be positioned at the supporting leg of wheel crane both sides according to the vertical distance between received vehicle frame and vehicle bridge plays lift operations, with the degree of the tire and earth surface that control wheel crane; Or control indicating device according to the vertical distance between described vehicle frame and vehicle bridge and send indicator signal.
Specifically, control setup 102 only can control a lift operations of the supporting leg being positioned at wheel crane both sides according to the vertical distance between received vehicle frame and vehicle bridge, with the degree of the tire and earth surface that control wheel crane, also can control indicating device according to the vertical distance between received vehicle frame and vehicle bridge and send indicator signal, certainly, also can perform these two operations simultaneously.That is, control setup 102 can control a lift operations of supporting leg automatically according to the vertical distance between vehicle frame and vehicle bridge, also can control indicating device according to the vertical distance between vehicle frame and vehicle bridge and send indicator signal, with the lift operations reminding operating personal to control supporting leg, further, also can control indicating device while the lift operations automatically controlling supporting leg and send indicator signal.Those skilled in the art are to be understood that, the degree of tire and earth surface is larger, the tire brought and the friction force on ground also larger, effectiveness in vibration suppression is also more obvious, otherwise, the degree of tire and earth surface is less, the tire brought and the friction force on ground also less, effectiveness in vibration suppression is also more not obvious.
The arrangement of the supporting leg of wheel crane generally has H type and X-type two kinds, and Fig. 2 is the schematic diagram of the H type supporting leg that wheel crane provided by the invention has, and as shown in Figure 2, H type supporting leg has front leg strut 1 and rear support leg 2.Here only schematically illustrate H type supporting leg, the present invention goes for the wheel crane with any one supporting leg in H type or X-type.
Wheel crane is in operation process, loading rapidly, unloading or turning round under start and stop operating mode rapidly, there will be the phenomenon that low-frequency vibration is carried out in the overall direction (being particularly parallel to the direction that the front of vehicle is pointed on ground) being parallel to ground of vehicle frame.This low-frequency vibration can be alleviated by technical scheme provided by the invention.
Specifically, due in the process hoisting supporting leg, vehicle frame can play the elongation of the Vertical Cylinders of lift operations along with control supporting leg and raise, so the exposure level adjusting tire and ground by the vertical distance controlled between vehicle frame and vehicle bridge can adjust the size of the friction force between tire and ground, in this case, except supporting leg supports vehicle body and lift heavy load, and keep in touch in tire and ground, thus can be suppressed by the friction on tire and ground that wheel crane vehicle frame under handling situations is overall is being parallel to the low-frequency vibration in direction (being particularly parallel to the direction that the front of vehicle is pointed on ground) on ground, also can play good attenuating for the vibration of the aspect perpendicular to ground simultaneously.
The lift operations that rises that control setup 102 described above controls supporting leg according to the vertical distance between vehicle frame and vehicle bridge comprises: determine whether the vertical distance between vehicle frame and vehicle bridge is greater than predetermined length, vertical distance between vehicle frame and vehicle bridge is greater than predetermined length, control setup 102 controls stopping and hoisting supporting leg, those skilled in the art are to be understood that, in this case, operating personal should strain braking during standstill spanner (or switch), to limit the rotation of tire thus to utilize the friction force on tire and ground to carry out vibration damping.Thisly be greater than a predetermined length time control stop preset by the vertical distance between vehicle frame and vehicle bridge and only hoist supporting leg, can by the touch controls between tire and ground an appropriate suitable degree, namely when the vertical distance between vehicle frame and car sedan-chair is this predetermined length, tire can contact with ground, and the exposure level on tire and ground is unlikely to again the suspension system damaging wheel crane, the tire can using wheel crane self like this carries out vibration damping, and special dampening apparatus need not be set, and do not need to improve structure or strengthen.
