Further be, a pair of left side retaining roller and right retaining roller are housed in the said foundation, have the space that holds steel rope between this left side retaining roller and the right retaining roller.At this, thereby left side retaining roller and right retaining roller have been realized that foundation cooperates with rolling between the steel rope through this.
Further be that the periphery of said left side retaining roller and right retaining roller is provided with the roller groove that holds steel rope.Steel rope is placed on prevents in the roller groove that it from seesawing, and plays the effect of accurate limiting.
Further be that preceding connecting panel and back connecting panel that said foundation comprises relatively and is provided with at interval are before the two ends of the roll shaft of said left side retaining roller and the two ends of the roll shaft of right retaining roller are installed in respectively on connecting panel and the back connecting panel.Preceding connecting panel plays support, positioning action to left side retaining roller and right side retaining roller with the back connecting panel.
Further be; Connecting panel and back have on the connecting panel and are used for the draw-in groove that cooperates with each roll shaft before said; One end of the roll shaft of left side retaining roller is connected in the draw-in groove of back connecting panel; The interior also coupling nut of the draw-in groove of connecting panel before the other end is connected to, an end of the roll shaft of right retaining roller is connected in the draw-in groove of back connecting panel, and the other end is connected to the interior and coupling nut of draw-in groove of preceding connecting panel.This structure design can be convenient to the assembling of transom.
Further be, but said back connecting panel is to be connected formed opening-closing structure with the right panel piece through revolving joint by left plate that the roll shaft of said left side retaining roller and the roll shaft of right retaining roller are connected on left plate and the right panel piece.
During connecting panel, left side retaining roller can be done open and close movement with left plate and right panel piece respectively with right retaining roller, thereby after not dismantling, just can conveniently transom be installed on the steel rope under the situation of connecting panel before taking down.The revolving joint that uses can adopt hinge or hinge etc.
The weight stop gear of the application's hoisting crane comprises the weight that is hung in the limit switch below; This weight links to each other with the steel rope of hoisting crane through transom; This transom comprises a foundation that cooperates with the steel rope activity; Said weight is installed on this foundation, cooperates for rolling between said foundation and the steel rope.
Further be, a pair of left side retaining roller and right retaining roller are housed in the said foundation, have the space that holds steel rope between this left side retaining roller and the right retaining roller.
Further be that preceding connecting panel and back connecting panel that said foundation comprises relatively and is provided with at interval are before the two ends of the roll shaft of said left side retaining roller and the two ends of the roll shaft of right retaining roller are installed in respectively on connecting panel and the back connecting panel.
The beneficial effect of the utility model is: owing to taked the mode of rolling and cooperating between transom and the steel rope, so the application has effectively avoided the wearing and tearing between transom and the steel rope.
Description of drawings
Fig. 1 is the running condition figure of the application's transom.
Fig. 2 is the right elevation of Fig. 1.
Fig. 3 is the scheme of installation of the application's transom.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Shown in Fig. 1～2; Back connecting panel 1 and the preceding connecting panel 3 that weight connecting panel 7 is installed are provided with respectively the draw-in groove that cooperates with the roll shaft of the roll shaft of left side retaining roller 5 and right retaining roller 2; One end of the roll shaft of left side retaining roller 5 is connected in the draw-in groove of back connecting panel 1; Interior and the coupling nut 4 of the draw-in groove of connecting panel 3 before the other end is connected to; One end of the roll shaft of right retaining roller 2 is connected in the draw-in groove of back connecting panel 1, the interior and coupling nut 4 of the draw-in groove of connecting panel 3 before the other end is connected to, and the roll shaft of left side retaining roller 5 and a left side keep off between the roller 5 and being rotatably connected through bearing; Be rotatably connected through bearing between the roll shaft of right retaining roller 2 and the right retaining roller 2, and be equipped with the roller groove 10 that is used to hold steel rope 8 on the periphery of left side retaining roller 5 and right retaining roller 2; In addition, but said back connecting panel 1 is to be connected formed opening-closing structure with right panel piece 1b through hinge 6 by left plate 1a, and the roll shaft of said left side retaining roller 5 and the roll shaft of right retaining roller 2 are connected on left plate 1a and the right panel piece 1b.
