Fig. 3 is the A-A view in Fig. 2;
In figure: 1-drg, 2-guide rail, 3-gravity tensioning chain bar, 4-rope, 5-pulley, 6-stay cord, 7-cage frame, 8-counterweight, 11-brake control lever, 12-housing, 13-voussoir, 14-cylinder, 15-slipper, 16-adjusting bolt, 17-bracket, 18-pipe link, 19-setscrew nut, the oblique sliding rail of 121-, 151-brake surface.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The cage falling-proof device of building hoist as shown in FIG. 1 to 3, comprise: with affixed two drgs 1 of cage frame 7 and the gravity tensioning chain bar 3 hinged with cage frame 7, this gravity tensioning chain bar 3 is connected with hypervelocity flip flop equipment by rope 4, be connected with the brake control lever 11 of described drg 1 by stay cord 6, the below of this brake control lever 11 is provided with the pulley 5 affixed with cage frame 7, and described stay cord 6 is walked around this pulley 5.
Described drg 1 comprises: housing 12; Brake control lever 11, its middle part is hinged with described housing 12; Pipe link 18, hinged with one end of described brake control lever 11, with described housing 12 sliding block joints, the lower end of this pipe link 18 is provided with bracket 17, the top setscrew nut 19 that has been threaded; A pair of voussoir 13, affixed with described housing 12; And a pair of slipper 15, being connected and moving to center when making this slipper 15 upward sliding with the oblique sliding rail 121 on described housing 12, the bottom of this slipper 15 contacts with described bracket 17; Described slipper 15 is all inclined-plane with the opposite face of described voussoir 13 and is parallel to each other and parallel with described oblique sliding rail 121, and centre is provided with some cylinders 14 that contact with two inclined-planes.
Described bracket 17 is provided with adjusting bolt 16, for regulating the initial position of described slipper 15.
The brake surface 151 of described slipper 15 is circular arc, matches with circular guideway 2, makes brake friction area larger, and braking force is stronger and little to guide rail 2 surface damages.
Described gravity tensioning chain bar 3 is provided with counterweight 8, can make gravity tensioning chain bar 3 more easily reset.
Principle of work and the working process of the cage falling-proof device of this building hoist are as follows: hypervelocity flip flop equipment triggers on rope 4 and draws while sensing cage hypervelocity, gravity tensioning chain bar 3 upward movements, stay cord 6 pulls down brake control lever 11, the other end of brake control lever 11 drives bracket 17 upward movements, bracket 17 drives slipper 15 to move obliquely upward, thereby make slipper 15 hold guide rail 2 tightly and realize braking, friction force between slipper 15 and guide rail 2 makes slipper 15 further to tiltedly upper mobile, slipper 15 is embraced tighter and tighter until stop relative motion with guide rail 2, in braking procedure the reaction force acts of slipper 15 on cylinder 14 to avoid oblique sliding rail 121 stressed, after braking is removed, gravity tensioning chain bar 3 resets, thereby slipper 15 oliquely downward moves with guide rail 2 and separates under Gravitative Loads.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
