The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
A kind of Flat car connecting device, such as Fig. 1, Fig. 2, shown in Figure 3, comprise housing 6 (referring to Fig. 6), housing 6 hollows, housing 6 is to open front, housing 6 includes roof and diapire, have pinned hole 12 on the roof of housing 6, have spacing hole 11 on the diapire of housing 6, pinned hole 12 is corresponding about in the of 11 with spacing hole, pinned hole 12 and spacing hole's 11 interior bearing pins 7 that jointly are installed with, and bearing pin 7 upper ends are fixedly connected with pin cap 2, pin cap 2 and bearing pin 7 be structure as a whole (referring to Fig. 5), pin cap 2 is positioned at above the roof of housing 6, is provided with polyester bump rubber 5 in the housing 6, and polyester bump rubber 5 is " U " font structure, bearing pin 7 is positioned at the groove of polyester bump rubber 5, and the slot opening of polyester bump rubber 5 is positioned at housing 6 outsides.Described spacing hole 11 be " in " word shape, described bearing pin 7 lower ends are fixedly connected with locating dowel pin 10, locating dowel pin 10 is structure as a whole (referring to Fig. 5) with bearing pin 7, locating dowel pin 10 is corresponding with described spacing hole 11.Captive joint limited location plug 8 has position-limited trough 9 below the diapire of described housing 6 on the sidewall of spacing plug 8, and the lower end of described bearing pin 7 is positioned at spacing plug 8, and described locating dowel pin 10 is positioned at position-limited trough 9, and the diapire of position-limited trough 9 a wherein end is higher than the other end.Be fixedly connected with positioning plate 4 in the groove of described polyester bump rubber 5, positioning plate 4 is " U " font structure, and described bearing pin 7 is positioned at the groove of positioning plate 4.Be hinged with handle 1 on the described pin cap 2.Be fixedly connected with back up ring 3 above the roof of described housing 6, described pin cap 2 is positioned at back up ring 3.
Embodiment recited above is described preferred implementation of the present invention; be not that the spirit and scope of the present invention are limited; under the prerequisite that does not break away from design concept of the present invention; common engineering staff make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
Bearing pin among the present invention and pinned hole are for being flexibly connected, and the pin cap is positioned at above the roof of housing, and locating dowel pin is positioned at below the roof of housing, and locating dowel pin can not be deviate from from the roof of housing through pinned hole.When connecting two flat trucks, pulling first handle mentions bearing pin, then two flat trucks are drawn close, again bearing pin is put down, locating dowel pin is passed from spacing hole, after locating dowel pin is positioned at below the diapire of housing, hand-held handle is with the bearing pin 90-degree rotation, locating dowel pin just turns to lowest part outside position-limited trough diapire the highest, unclamp handle, and locating dowel pin is in the lowest part of position-limited trough diapire all the time under Action of Gravity Field, locating dowel pin can be through spacing hole's prolapse upwards, guarantee the safe operation of flat truck, improved the reliability that connects in the transportation, realized the safety of transportation.
The present invention utilizes the locking pin principle to transform, and uses the principle of equal anticreep pin, and anti-drop device is shortened, and changes upper anticreep fixed type into lower anticreep fixed type, and handle adopts the elastic foldable formula, proposes during use, and the time spent is not bumped in the groove (being the back up ring).Because the polyester bump rubber has elasticity, larger elastic deformation is arranged, can avoid the direct rigidity punching to rush, cushioned the impulsive force of vehicle, avoided the flat truck because of the slide down generation of phenomenon of collision, satisfied the regulation of " safety regulations in coal mine " the 363.
After using the present invention, can reduce in the main equipment transportation, especially the time of dislodging pin is installed, withdrawn to down-hole combined mining working, cancelled connecting and triped, every day, each car can be saved 3 hours haulage time, for the time striven for is installed, withdrawn to driving surface.
