Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
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 relaxation of trailing cable 2 is fixed on after bypassing cable sheave 6 In cage 9, the other end of haulage cable 4 bypasses the load pull bar that connecting fault after wire rope pulley 5 detects protection device 3 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 with 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 Cable sheave 6 is with diameter greater than wire rope pulley 5, or, wire rope pulley 5 is under, and wire rope pulley 5 is with diameter greater 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 ensures 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 and casing top.It is described Extension spring 12 has one or more, and adjusting yoke 11 is also to that should have one or more.Many extension springs 12 can directly with Load pull bar 15 is connected, 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;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, and the other end is bypassed after 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 is connected, and should be adjusted the length of haulage cable 4 and ensured 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.
When cage 9 and cable coaster 7 are normally run, only two extension springs 12 bear traction by load pull bar 15 Whole service loads that steel wire rope 4 is passed 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.
During the decline of cage 9, relaxation, such as Fig. 3 occurs in the event of jam, haulage cable 4 in cable coaster 7 Shown, the pulling force that haulage cable 4 acts on load pull bar 15 reduces, the resilience contracting upwards because of pulling force reduction of extension spring 12 It is short, and drive spacing detection plate 13 to move up, when stroke reaches to a certain degree, the control on the cut-out cage 9 of travel switch 18 Circuit processed, cage 9 stop it is descending, while alarm lamp is bright in cage 9.
In the uphill process of cage 9, cable coaster 7 can be tensed extremely in the event of jam, haulage cable 4, such as Shown in Fig. 4, the pulling force increase on load pull bar 15, extension spring 12 elongates downwards compression spring 14 simultaneously and is compressed downwardly contracting It is short, drive spacing detection plate 13 to move down, when stroke reaches to a certain degree, touch on the cut-out cage 9 of travel switch 18 Control circuit, cage 9 stop it is up, while alarm lamp is bright in cage.
This programme is simple in construction, novel in design, function is more complete and high using reliability, can greatly improve construction lifting The security reliability that machine is used.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, under the premise without departing from the principles of the invention, some improvement or deformation can also be made, these, which improve or deformed, also should It is considered as protection scope of the present invention.
