Description of drawings
Fig. 1 is the utility model structural representation
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is elaborated: present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises: underframe 1, plum blossom wheel 2, left brake block 3, right brake block 4, left brake control lever 5, right brake control lever 6, left hinged plate 7, right hinged plate 8, connect setting device 9, spring attachment 10, reset attachment 11, swing arm re-pack device 12, brake triggering device 13.
Annexation between the above-mentioned parts is: underframe 1 is fixed in the lifting mechanism, plum blossom wheel 2 is fixed on the reel ends of lifting mechanism, left side brake block 3 is hinged on the left brake control lever 5, right brake block 4 is hinged on the right brake control lever 6, one end of left side brake control lever 5 is hinged on underframe 1 left end, the other end and left hinged plate 7 are hinged, one end of right brake control lever 6 is hinged on underframe 1 right-hand member, the other end and right hinged plate 8 are hinged, one end of the hinged plate 7 in a left side is hinged with an end of right hinged plate 8 by connecting setting device 9, the other end of the hinged plate 7 in a left side is hinged with the other end of right hinged plate 8 by spring attachment 10, reset attachment 11 is hinged on the right hinged plate 8, the swing arm device 12 that re-packs is hinged on the right brake control lever 6, and brake triggering device 13 is hinged on the right hinged plate 8.
Described connection setting device 9 is made up of left and right sides screw-casing and left and right sides tie bolt, is used to connect left hinged plate 7, right hinged plate 8, can adjust the relative position of left hinged plate 7, right hinged plate 8.
Described spring attachment 10 is under normal condition, and spring is in compressive state.
Described reset attachment 11 is made up of spring bearer plate and coes wrench, and spring bearer plate is hinged on the right hinged-support 8, and coes wrench is fixed on the spring bearer plate, is used for unclamping left brake block 3, the right brake block 4 of locking.
