Background technology
Current elevator, conventionally be all to adopt chain or rope to be connected with lifting table, as in high-level stereo garage, to drive chain or rope to promote lifting table with the multi-storied garage of chain suspension or steel wire hang circulation by lifting motor, and chain or rope are in the course of the work, after use certain hour, can not avoid being damaged causes chain or rope to disconnect, if there is no elevator process falling protector, the accident of lifting table tenesmus will occur.Existing lifting process falling protector, is arranged on mouth or the motor output shaft end of power conventionally, once chain or rope fracture, falling protector will be ineffective, and falling protector is more complicated and cost is high in structure aspects.
Utility model content
The purpose of this utility model is to provide a kind of process falling protector, and it causes the problem of lifting table tenesmus accident can solve the fault such as elevator generation chain or rope disconnection time this process falling protector.
In order to address the above problem, the technical solution adopted in the utility model is:
This process falling protector, include and be movably arranged on the movable voussoir that is provided with chute in crane cross, described movable voussoir is connected with the shift fork of lever one end, and the shift fork of the described lever other end is connected with the push rod that stretches out electromagnet: the other end of described push rod stretches in spring spool and is connected with spring.
In above technical scheme, further scheme is: described movable voussoir is arranged on the A-frame in crane cross, and the chute of described movable voussoir is contained on the axle that can move along crane cross; On described movable voussoir, be provided with setting nut and hexagonal nut; The fulcrum of described lever is arranged on plectrum support; Described electromagnet is arranged on being pressed on the voussoir briquetting on described movable voussoir of being connected with crane cross.
Further: in described crane cross, just the setting nut of described movable voussoir to be provided with to micro limit switch.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, the utility model, in the time of the faults such as elevator generation chain or rope disconnection, because movable voussoir is stuck in anti-fall fixture block, supports whole lifting table, has avoided the tenesmus of lifting table, has prevented the generation of accident.
2, the utility model is simple in structure, operate easy for installation, long service life, dependable performance safety.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the position view that the utility model is arranged on elevator; Four root posts that figure central post 1,4,6,8 is elevator; Vehicle-carrying plate 5 is arranged in four root posts, and process falling protector 2,3,7,9 is the process falling protector that is arranged on respectively four the utility model indications in vertical rod; Fig. 2 is anti-fall fixture block 12 installation site structural representations in upright post of elevator.Fig. 3 is upright post of elevator schematic top plan view; Upright post of elevator is by being vertically welded with C shaped steel 14 on base plate 10, C shaped steel 14 opening both sides are respectively arranged with rectangular tube 11 and angle steel 13, and anti-fall fixture block 12 intervals are arranged on angle steel 13.
The process falling protector of Fig. 4 and Fig. 5, include the movable voussoir 19 being movably arranged in crane cross 15, movable voussoir 19 is connected with the shift fork of lever 26 one end, the shift fork of lever 26 other ends is connected with the push rod that stretches out electromagnet 22: the other end of described push rod stretches in spring spool 20 and is connected with spring 21, and it is the electromagnet of SA-3502 that electromagnet 22 adopts model; On electromagnet 22 and lever 26, be provided with guard shield 24.
In described crane cross 15, just the setting nut 16 of movable voussoir 19 is provided with to micro limit switch 27.
Anti-fall principle of the present utility model is described as follows: if Fig. 6 is incipient state, movable voussoir 19 is between two anti-fall fixture blocks 12, under the effect of spring 21, make electromagnet 22 in ejecting state, plectrum support 25 and two have the plectrum of shift fork to form lever 26, lever 26 is stirred movable voussoir 19 by the hexagonal nut 17 being fixed on movable voussoir 19, make movable voussoir 19 in stretching out state, put between two 12 anti-fall fixture blocks.Along with the rising of vehicle-carrying plate 5, Four processes falling protector 2,3,7,9 is also followed the tracks of rising, until as shown in Figure 7, movable voussoir 19 and anti-fall fixture block 12 are collided, and due to inclined-plane between the two, make compressed the going back of anti-fall fixture block 19, be compressed to state as shown in Figure 8 always, when vehicle-carrying plate 5 continues to rise, to Fig. 9 state, anti-falling wedge block 19 is ejected again.Can know by a series of actions above, as long as 19 movable voussoirs will stretch out when anti-falling wedge block 19 runs to the space of 12 of anti-fall fixture block, to reach fall arrest object.When in decline process, in order to allow four falling protectors can open and not allow movable voussoir 19 and anti-fall fixture block 12 mutually encounter simultaneously, micro limit switch 27 plays detection effect, the setting nut 16 being simultaneously arranged on anti-falling wedge block 19 plays fine setting effect, can eliminate the error due to processing and the existence of installation aspect, make movable voussoir 19 can encounter micro limit switch 27, allow micro limit switch 27 collect signal, ensure the normal lifting of elevator.
