Embodiment
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
The present embodiment provides the system of cable coaster 7 of a kind of building hoist tape jam detection and automatic protection, such as Fig. 1 institutes
Show, including fixing device 1, cable coaster 7, fault detect protection device 3, trailing cable 2 and haulage cable 4, fixing device 1
A high position for guide rail bracket 8 is fixedly connected on, fault detect protection device 3 is fixed on cage 9, and cable coaster 7 can be by multiple
Directive wheel is slidably connected with guide rail bracket 8, and the side of cable coaster 7 sets cable sheave 6 and wire rope pulley 5, the He of trailing cable 2
One end of haulage cable 4 is both secured on fixed mount, and the other end of trailing cable 2 relaxes around being fixed on after cable sheave 6
In cage 9, the other end of haulage cable 4 bypasses the load pull bar of connecting fault detection protection device 3 after wire rope pulley 5
15；As shown in Fig. 2 fault detect protection device 3 includes built-in travel switch 18 and the casing of spacing detection plate 13, casing top
Adjusting yoke 11 is fixedly installed, load pull bar 15 is stretched into casing by bottom half and connected by extension spring 12 and adjusting yoke 11
Connect, spacing detection plate 13 is fixedly installed on load pull bar 15, is fixed with fixture 17, and the load below spacing detection plate 13
Compression spring 14 is arranged on lotus pull bar 15, the rigidity of extension spring 12 is less than the rigidity of compression spring 14.
Further, the axis of the cable sheave 6 and wire rope pulley 5 totally one vertical plane, cable sheave 6 under, and
The diameter of cable sheave 6 is more than wire rope pulley 5, or, wire rope pulley 5 is under, and the diameter of wire rope pulley 5 is more than cable sheave
6。
Further, the cable trough of the cable sheave 6 is non-target deep groove structure.So that no matter be up or
Generation jam, all ensure that trailing cable 2 is in relaxed state all the time, protects trailing cable 2, such as Fig. 5 ~ Fig. 8 institutes to greatest extent
Show.
Further, the adjusting yoke 11 is stretched out by casing top and fixed by nut 16 with casing top.It is described
Extension spring 12 has one or more, and adjusting yoke 11 is also corresponding with one or more.More extension springs 12 can directly with
Load pull bar 15 connects, and can also be connected respectively at the accepting of spacing detection plate 13.
Further, the warning lamp coupled with travel switch 18 is set in the cage 9.
Further, the travel switch 18 is mechanical trip switch, and spacing detection plate 13 is provided with collision block；It is or, described
Travel switch 18 is photoelectric travel limit switch.
Installation process：After fixing device 1, cable coaster 7 and trailing cable 2 are respectively mounted in place, haulage cable 4
One end is fixed in fixing device 1, after the other end is around the wire rope pulley 5 on cable coaster 7, with being fixed on cage 9
Load pull bar 15 in fault detect protection device 3 connects, and should adjust the length of haulage cable 4 and ensure that trailing cable 2 is appropriate
Relax, then locking nut 16, now load pull bar 15 is under the Gravitative Loads of cable coaster 7 and haulage cable 4, with compression
The rigid connection of spring 14 is touched, but also without compressive deformation, the center line of dedicated location mark line and travel switch 18 in spacing detection plate 13
Overlap.
In 7 normal operation of cage 9 and cable coaster, only two extension springs 12 bear to draw by load pull bar 15
Whole service loads that steel wire rope 4 passes over, now according to the length of haulage cable 4 and the change of deadweight, compression spring 14
In normal relaxation or slight pressured state.
