Detailed description of the invention:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
Embodiment 1
As shown in the figure, one automatically resets castor, be made up of fixed panel 2, bearing, trundle bracket 5, castor 6, automatic reset device 7, described bearing comprises bearing outside 3 and bearing inner sleeve 4, and bearing inner sleeve 4 is fixed on fixed panel 2 center, and bearing outside 3 is socketed on bearing inner sleeve 4, trundle bracket 5 top is fixed on bearing outside 3, bottom attaching has castor 4, relies on the effect of bearing, castor 4 can under certain External Force Acting left-right rotation.Described fixed panel 2 is fixedly mounted on the bottom of haulage equipment 1.
Described automatic reset device 7 is made up of center shaft 71, cam 72, front automatic extending-contracting apparatus 73 and rear automatic extending-contracting apparatus 74.
Front automatic extending-contracting apparatus 73 is made up of front stretching pipe box 731, front slide thimble 732, front spring 733 and front tight split nut 734.Described telescopic tube 731 inside is run through cylindricality slip cavity 735, and its afterbody circular open is comparatively large, head circular opening is less; Described front slide thimble 732 head is arc raised face.Front slide thimble 732 interts in cylindricality slip cavity 735, its head extends front stretching pipe box 731 head, front spring 733 props up front slide thimble 732 afterbody, front tight split nut 734 is screwed in front stretching pipe box 731 afterbody, front spring 733 and front slide thimble 732 is locked in front stretching pipe box 731.
Described rear automatic extending-contracting apparatus 74 is symmetrical structure with front automatic extending-contracting apparatus 73.
Described cam 72 is the elliptical configuration of the long width in left and right, the short width in front and back, is symmetrically arranged with front arc groove 721 and the rear arc groove 722 of Vertical dimension in the minor axis extension of cam 72.
Described front automatic extending-contracting apparatus 73, automatic extending-contracting apparatus 74 symmetry are fixedly mounted on the front and back position of bearing outside 3 bottom.The fixedly sleeved center at bearing inner sleeve 4, described center shaft 71 top, cam 72 is fixedly mounted on center shaft 71 bottom, is in same level with automatic extending-contracting apparatus 73, automatic extending-contracting apparatus 74.Front slide thimble 732 and rear slip thimble 742 are pushed against on front arc groove 721 and rear arc groove 722 respectively in opposite directions.
As shown in Figure 5, when haulage equipment 1 is when bearing a heavy burden mobile, by certain External Force Acting, castor 6 drives castor leg 5, bearing outside 3, front automatic extending-contracting apparatus 73 and rear automatic extending-contracting apparatus 74 to be in steering position.Front slide thimble 732 and rear slip thimble 742 slide off front arc groove 721 and rear arc groove 722, be pushed against the position of the longer axis of cam 72, front slide thimble 732, rear slip thimble 742 are respectively to front stretching pipe box 731, the displacement of rear flexible pipe box 741 afterbody, and compress front spring 733 and rear spring 743, make it to put aside energy.When haulage equipment 1 to be scooped up by forklift or moves away from bottom surface, the external force of castor 6 is disappeared, under the promotion of front spring 733 and rear spring 743, the effect that front slide thimble 732 and rear slip thimble 742 act on the oblong surface of cam 72 forms the component that one is pointed to front arc groove 721 and rear arc groove 722, drive front automatic extending-contracting apparatus 73 and rear automatic extending-contracting apparatus 74, bearing outside 3, castor 6 resets and rotates, when front slide thimble 732 and after slip thimble 742 head slip in front arc groove 721 and rear arc groove 722 respectively, reset completes, castor also just automatically restores to craspedodrome state.Now haulage equipment enters operating line and will keep straight on, the generation of the bad situation such as collision free.
