A kind of automatic leveling detection device that is used for connecting bridge of
the present invention, owing to adopt such structure, when needs leveling wheel contacts detectable signal with body, the electric pushrod action, the leveling wheel leans on upper machine body; Limit cam is with after spacing bit switch contacts, the electric pushrod outage, and the effect of tension spring and four bar detent mechanisms keeps and fully the contacting of body the leveling wheel, and the assurance detectable signal is accurately and reliably; In the whole process of meeting sb. at the airport, no longer consumes energy.Meet sb. at the airport after the completion, the leveling wheel resets, limit switch and limit cam effect, outage.
Description of drawings
Fig. 1 is a three-dimensional exploded view of the present invention.
Fig. 2 is the meet sb. at the airport front view of state of the present invention.
Fig. 3 is the front view under the non-state of meeting sb. at the airport of the present invention.
The specific embodiment
further describe the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of automatic leveling detection device that is used for connecting bridge comprises leveling arm 1 and the leveling wheel 2 that is articulated in leveling arm 1 end, also comprises bearing 3, limit cam 4, limit switch 5, four bar detent mechanisms, driver train and a hold-down mechanism;
Said driver train comprises an electric pushrod 61, a push arm 62 and a rotating shaft 63; The slide of electric pushrod is fixed on the after poppet 32 of bearing 3; Push arm 62 and rotating shaft 63 running-fits; Rotating shaft 63 articulates with the front frame 31 of bearing 3, and push arm 62 is between two bogie side frames of front frame 31, captives joint with leveling arm 1 in rotating shaft 63 ends; The push rod of electric pushrod 61 and push arm 62 articulate;
Said hold-down mechanism is one or four bar detent mechanisms, and said four bar detent mechanisms comprise first connecting rod 71, second connecting rod 72, third connecting rod 73 and extension spring assembly 74;
After poppet 32 pivot joints of the upper end of first connecting rod 71 and bearing 3, the lower end of first connecting rod 71 and an end of second connecting rod 72 articulate the extension spring of extension spring assembly 74 and pivotal joint with a pivot;
Captive joint with rotating shaft 63 in the upper end of third connecting rod 73, the bar portion of the lower end of third connecting rod 73 and extension spring assembly 74 articulates;
second connecting rod 72 articulates with push arm 62.
the present invention in use, when meeting sb. at the airport, the contact pickup action of meeting sb. at the airport mouthful, the connecting bridge stop motion, electric pushrod 61 drives push arm 62 and rotates counterclockwise by stretching out the state retraction.When being fixed on limit cam 4 in the rotating shaft 63 with after limit switch 5 contacts, electric pushrod 61 stop motions, as shown in Figure 2.
