Further improvement, described protective cover adopts transparent PC (polycarbonate) force-bearing plate to make.Protective cover of the present utility model adopts transparent PC (polycarbonate) force-bearing plate to make, and its main purpose is for the ease of observing elevator governor.
Further improvement, described protective cover comprises first cover and second cover; First cover described and second cover are provided with connection hole.Its objective is and make, select protective cover partly shirk or entirely shirk according to velocity limiter maintenance repair and observation demand.
Further improvement, described protective cover is cuboid.The profile of the protective cover in the utility model can design according to the locus of erecting stage, and the utility model does not limit concrete shape, and just when locus is permitted, the utility model preferentially selects cuboid.Cuboid is easy to make, and outward appearance is simply generous.
Velocity limiter described in the utility model is the velocity limiter in application of the prior art and elevator, and its concrete structure the utility model does not elaborate.
Compared with prior art, its beneficial effect is the utility model:
1, rat preventing device of the present utility model, make simple, highly versatile, cost is low, and meet and install demand additional in enormous quantities, installation effectiveness is high, and shirks when being convenient to later stage velocity limiter maintenance repair and verification.
2, in the utility model, the installation site of steel rope protection against rodents back-up ring, under velocity limiter lower shoe, adopts the erection method of semicircle ring type, achieves and installs additional exempting from dismounting with elevator.
3, in the utility model, protective cover adopts transparent PC (polycarbonate) force-bearing plate to make.This material has light transmission, weather resisting property, shock resistance, and adaptive temperature scope, at-40 DEG C ~ 120 DEG C, meets elevator(lift) machine room environmental requirement.Fire-retardant, sound insulation, heat insulation.Possesses good processability simultaneously.
