The specific embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of hydraulic elevator safety protection device for lift car, comprise for by car locking the safety tongs 1 on cage guide 15, for lifting safety tongs attaching parts 2, the first transmission shaft 3 and the second driving shaft 4 of described safety tongs, described the first transmission shaft is located at described second driving shaft top, on described the first transmission shaft, overlap intrinsic the first shifting part 5 and the first attaching parts 6, between the bearing of trend of described the first shifting part and the bearing of trend of described the first attaching parts, be setting angle; On described second driving shaft, overlap intrinsic the second shifting part 7 and the second attaching parts 8, between the bearing of trend of described the second shifting part and the bearing of trend of described the second attaching parts, be setting angle; Between described the first attaching parts and described the second attaching parts, be provided with one the 3rd attaching parts 9, the free hinge ending connection of one end of described the 3rd attaching parts and described the first attaching parts, the free hinge ending connection of the other end of described the 3rd attaching parts and described the second attaching parts; The free end of described the first shifting part is by fag end combination 10 steel ropes 11 that are connected on traction car, and the free hinge ending connection of described the second shifting part is in described safety tongs attaching parts, and described safety tongs attaching parts is fixedly connected with described safety tongs.Like this, when there is safety failure in hydraulic elevator, during as the wire cable rupture of traction, fag end combination loses tractive force, the thrust of rotating to the first shifting part one, under the effect of fag end combination thrust, the first shifting part rotates, and drive the first transmission shaft to rotate, the first transmission shaft rotates and then drives solid the first attaching parts thereon of cover upwards to rotate, the first attaching parts upwards rotates the upper end lifting with the 3rd attaching parts of its hinge, and then drive the lower end of the 3rd attaching parts upwards to rotate, and drive the second attaching parts upwards to rotate, the second attaching parts upwards rotates and drives second driving shaft to rotate, solid the second shifting part thereon of second driving shaft rotating drive cover upwards rotates and lifts safety tongs attaching parts, final safety tongs attaching parts upwards lifts safety tongs, car is locked on guide rail.Hydraulic elevator safety protection device for lift car of the present invention is actually by the formation shift mechanism that links and realize replaces velocity limiter and trigger safety tongs as from the foregoing; when there is safety failure in hydraulic ladder; as wire cable rupture; interlock shift mechanism can trigger safety tongs; safety tongs action; car is stuck on guide rail, and can not drops, and then reach the object that ensures elevator safety.Therefore, the present invention triggers safety tongs action without using velocity limiter to handle, and for elevator, installs and has saved space, has reduced cost, makes some extra small hoistway lift-mountings become possibility, and has the advantages such as simple in structure, safe and reliable, cheap.
Preferably, be provided with two described the first shifting parts, two described the first shifting parts are located at the place, two ends near described the first transmission shaft, described the first attaching parts is located at the middle part of described the first transmission shaft, described the second attaching parts is located at the middle part of described second driving shaft, and corresponding up and down with described the first attaching parts.
Preferably, corresponding each first shifting part, be provided with two described fag end combinations, described in each, fag end combination comprises guide bar 101, fag end spring 102 and fag end body 103, described steel rope is fixed in the upper end of fag end body, the lower end of described fag end body is fixedly connected with the upper end of described guide bar, and the lower end of described guide bar is fixedly connected with described the first shifting part through a rope hitch plate 121 that is connected elevator car frame 12; Described fag end spring housing is located on described guide bar, and the upper end backstop of described fag end spring is in the bottom of described rope hitch plate, the upper end of the stop block 104 that the lower end backstop of described fag end spring sets firmly in the lower end of described guide bar.During concrete enforcement, stopper is the nut that is threaded in guide bar lower end, like this, and under normal circumstances, car weight makes fag end spring always in confined state, once upper end wire cable rupture, spring loses pressure, and spring is upspring, stop block is under the application force of fag end spring, drive guide bar moves downward, and fag end body moves downward in company with guide bar and backstop in the upside of rope hitch plate, owing to being positioned at the length of the guide rod of rope hitch plate downside, extend, therefore, can drive the first shifting part to rotate.
Preferably, the two ends of close described second driving shaft are provided with for making the activity brake of described safety tongs carve piece and in normal position, obtain torsion spring 13.Like this, when normal condition or reset, the activity brake of the torsion assurance safety tongs of the torsion spring on second driving shaft is carved piece in normal position, misoperation while avoiding moving.
Preferably, on described second driving shaft, be provided with for connecting the UKS switch 14 of safety return circuit line source.Like this, when when there is safety failure in hydraulic elevator, while rupturing as traction steel-cable, under the effect of fag end combination thrust, the first shifting part drives the first transmission shaft, the first attaching parts, the 3rd attaching parts, the second attaching parts, second driving shaft, the second shifting part successively, and drives on safety tongs attaching parts and carry, safety tongs is lifted to brake to be fixed on car guide rail, UKS switch on second driving shaft cuts out simultaneously, and safety return circuit disconnects, and lift car is out of service.Safety tongs interlock shift mechanism of the present invention and UKS switch gearing; during mechanical mechanism action, UKS switch also can move; disconnect its safety return circuit switch, electric control system is carried out elevator stoppage in transit protection, and actv. guarantees the function of safety protection of safety tongs device more.
Above embodiment is with reference to accompanying drawing, to a preferred embodiment of the present invention will be described in detail.Those skilled in the art is by above-described embodiment being carried out to modification or the change on various forms, but do not deviate from the situation of essence of the present invention, within all dropping on protection scope of the present invention.
