Abstract
A secure trigger device comprises a flexible shaft pull core (01), a pressing shaft (02), a threaded cap (03), a sleeve (04), a pressing spring (05), a T-shaped key (06), a swing rod (07), a through pin (08), a steel wire rope (09) and a support (10). The flexible shaft pull core (01) is movably connected with the pressing shaft (02) which penetrates the threaded cap (03) to be disposed in the sleeve (04). The threaded cap (03) is fixed at the front end of the sleeve (04). The pressing spring (05) is wound on the pressing shaft (02), one end is pressed against the threaded cap (03), and the other end is pressed in the sleeve (04). The T-shaped key (06) penetrates the sleeve (04) to be in guiding sliding connection with the pressing shaft (02), the swing rod (07) penetrates the through pin (08) to be in rotary connection with the pressing shaft (02) and is in contact connection with the steel wire rope (09), and the sleeve (04) is fixedly connected with a lift car (11) through the support (10). The device has the advantages of being visual, simple, reliable and capable of solving the security problem well.
Description
Technical field: the utility model relates to a kind of safe flip flop equipment, especially a kind of safe flip flop equipment for elevator.
Background technology: the mode great majority of elevator safety mechanism safety effect performance are at present by electric, by the quickening of the speed of falling, by sensor, finally prevents the generation of lift car falling accident again by mechanical mode.Because control process link is many, prevent that the reliability that falling accident occurs from reducing; In control process, any one link safety gear that all can make out of joint loses safety effect.
Summary of the invention: for above-mentioned the deficiencies in the prior art, the utility model provides a kind of simple in structure, direct, reliable, safe flip flop equipment that safe effect is more secure.
For achieving the above object, the technical solution adopted in the utility model is: a kind of safe flip flop equipment, comprises that flexible axle draws core (01), apical axis (02), screw thread block (03), sleeve (04), top spring (05), T-shaped key (06), fork (07), wears pin (08), steel rope (09) and support (10); Wherein flexible axle draws core (01) to be flexibly connected with apical axis (02).Apical axis (02) is blocked a shot (03) in sleeve (04) through screw thread; Screw thread block (03) is fixed on the front end of sleeve (04); Top spring (05) is being wound around apical axis (02), and it is upper that its one end withstands on screw thread block (03), and the other end withstands in sleeve (04).T-shaped strong (06) is inserted in the hole of sleeve (04) and is fixedly connected with sleeve (04), and is connected with the keyway slide-and-guide on apical axis (02).Sleeve (04) is rotationally connected with apical axis (02) by wearing pin (08) with apical axis (02) guiding sliding block joint, fork (07), and fork (07) is connected with steel rope (09) contact, and sleeve (04) is fixedly connected with car (11) by support (10).
The technical scheme that the utility model proposes has intuitively, and simple, failure-free feature, has solved the problem of safety well.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1
Fig. 3 is the birds-eye view of Fig. 1.
The specific embodiment:
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, intactly description, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Give the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-Figure 3: a kind of safe flip flop equipment, comprises that flexible axle draws core 01, apical axis 02, screw thread block 03, sleeve 04, top spring 05, T-shaped key 06, fork 07, wears pin 08, steel rope 09 and support 10; Wherein flexible axle draws core 01 to be flexibly connected with apical axis 02.Apical axis 02 blocks a shot 03 in sleeve 04 through screw thread; Screw thread block 03 is fixed on the front end of sleeve 04; Top spring 05 is being wound around apical axis 02, and its one end withstands on screw thread block 03, and the other end withstands in sleeve 04.T-shaped strong 06 is inserted in the hole of sleeve 04 and is fixedly connected with sleeve 04, and is connected with the keyway slide-and-guide on apical axis 02.Sleeve 04 and apical axis 02 guiding sliding block joint, fork 07 is rotationally connected with apical axis 02 by wearing pin 08, and fork 07 is connected with steel rope 09 contact, and sleeve 04 is fixedly connected with car 11 by support 10.
Principle of work: elevator is normal use in steel rope 09 carrying the total weight of lift car 11, steel rope 09 is in tensioned state, makes top spring 05 in compressive state tightening steel rope 09 under power effect by fork 07, apical axis (02); In elevator is used, when one or both sides steel rope 09 is unexpected, disconnect, or steel rope 09 loses the power of tightening while throwing off, and also loses steel rope 09 by the compressive force of fork 07,02 pair of spring 05 of apical axis, to apical axis 02 is ejected under the effect of top spring 05; Apical axis 02 draws core 01 to pull safety tongs flip flop equipment by flexible axle, and safety tongs is had an effect, and safety tongs and guide rail are locked, prevents the generation of car falling accident.
