Embodiment

For making object of the present invention, content and advantage clearly, below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.

Embodiments provide a kind of position and lock mechanism connected for many cars, as shown in Figure 1, comprise docking hook lock module 1 and fixed guide module 2, be connected in two different car body structures respectively by bolt.Docking hook lock module 1 and the every chassis of fixed guide module 2 generally fill two groups, and symmetrical installation.

The realization of docking hook lock module as shown in Figure 2, guiding taper pin 4 is weldingly fixed in hook lock module body 3 by border, back, lower latch hook 5 and upper latch hook 7 are arranged in hook lock module body 3 respectively by lower bearing pin 6 and upper pin 8, and lower latch hook 5 freely can rotate around lower bearing pin 6, upper latch hook 7 freely can rotate around upper pin 8.Electric pushrod 9 is connected with upper latch hook 7 by upper fixing pin 10, is connected with lower latch hook 5 by lower fixing pin 11.Lower limit screw 12, upper limit screw 13 are arranged on the tapped hole of hook lock module body 3, by adjust suitable position can limit electric pushrod 9 when most short status on latch hook 7 be in symmetrical position with lower latch hook 5.By set the stroke of electric pushrod 9 can realize electric pushrod 9 be in stretch out state time, upper latch hook 7 is just in locked position with lower latch hook 5.Upper non-contact type approach switch 14, lower non-contact type approach switch 15 are arranged on the docking reference level of hook lock module body 3, by the length adjusting upper non-contact type approach switch 14, lower non-contact type approach switch 15 stretches out, when docking hook lock module 1 approaches to certain position with fixed guide module 2, upper non-contact type approach switch 14, lower non-contact type approach switch 15 provide approach signal.

The realization of fixed guide module as shown in Figure 3, is welded by some steel plates and reinforcement gusset, and the interface of fixed guide module 2 is processed with two locking inclined-planes 17 of butt hole 16 and upper and lower symmetry.

The implementation procedure of the position and lock mechanism connected for many cars provided by the invention as shown in Figure 4, is separately installed with the car A of two docking hook lock modules 1 and fixed guide module 2 and car B and first adjusts the relative position of two cars and close gradually.When the butt hole 16 of the guiding taper pin 4 that car A docks hook lock module 1 close to car B fixed guide module 2, because guiding taper pin 4 front end is much little compared with butt hole 16, so be easy to enter in butt hole 16, after the guiding taper pin 4 of the car A left and right sides all enters the butt hole 16 of car B, under the guiding of lead taper pin 4 and pilot hole 16, two cars continue close, the end face of docking hook lock module 1 and fixed guide module 2 will close to time, upper non-contact type approach switch 14, lower non-contact type approach switch 15 detects proximity state, and report control system, what control system provided electric pushrod 9 after approach signal being detected stretches out signal.When electric pushrod 9 stretches out, under the effect of the lever of upper latch hook 7, lower latch hook 5, upper latch hook 7, lower latch hook 5 are close with the upper and lower locking inclined-plane in fixed guide module 2 respectively, and utilize the effect of upper and lower locking inclined-plane guiding force docking hook lock module 1 and fixed guide module 2 to be strained, realize two locks fixed.During the release of position and lock mechanism, electric pushrod 9 bounces back to most short status, and upper latch hook 7, lower latch hook 5 depart from from upper and lower locking inclined-plane, handle two garages and sail out of out.

The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
