Abstract

The utility model relates to a non-transform plate brake for an elevator. The plate brake has the structure that a base and a movable iron plate are opposite to each other; a friction plate is connected to the outer side of the movable iron plate; and a toroidal coil winding is mounted inside the base. The improvement of the plate brake is that a plate-shaped spring leaf or a column-shaped spiral spring for braking is mounted on the base in the toroidal coil winding ring. The position of the retarding spring in the utility model is changed into the middle part of the base in the toroidal coil winding ring from four corners of the base outside the toroidal coil winding ring, so that the outward push effect of the original retarding springs at four corners to the upper end and the lower end of the movable iron plate is removed; and the possibility of the movable iron plate to curve and transform is eliminated. The movable iron plate has the advantages of small size, low heating, uniform force bearing, and non-curving and transformation, and the braking torque is convenient to adjust, so that the safety of the elevator can be improved.

Description

No snyed plate block brake

Technical field

The utility model relates to a kind of elevator magnet stopper, specifically a kind of no snyed plate block brake.

Background technology

The elevator magnet stopper is a kind of electromagnetism electricity loss brake, mainly includes several forms such as hub type brake, caliper brake, plate disc brake and device of shifting block type drg.Wherein the structure of device of shifting block type drg is that pedestal is relative with moving iron plate, is connected to friction lining in the moving iron plate outside, and parts such as long toroid winding winding and retarding spring are housed in pedestal.Retarding spring is some cylindrical helical springs, is arranged on the peripheral neutral of the wire casing place of four jiaos of pedestals.Because retarding spring is to be to rely on moving iron plate is applied export-oriented thrust with the pedestal all the time, this just makes the upper/lower terminal of moving iron plate be subjected to an extrapolation application force all the time; And the middle part of moving iron plate can be subjected to the inside squeezing action power of brake wheel at glancing impact.Under the effect of above-mentioned two kinds of oppositions, the moving flexural deformation of iron plate after long-term use is also just unavoidable, and this flexural deformation meeting directly causes brake failure, thereby bigger to the threat safe in utilization of elevator.

For improving the counter-bending ability of moving iron plate, people have to give up the pure iron material, then use the 45# steel or use 65 manganese spring steel plates to make moving iron plate.Use these materials, though improved the bending resistance of moving iron plate, because of its magneto-conductivity is low, so cause the braking strength of drg little, heating is high.Thereby the device of shifting block type drg after the material conversion still has the deficiency in the use.

The utility model content

The purpose of this utility model just provides a kind of no snyed plate block brake, to overcome the technological deficiency that existing device of shifting block type drg exists, guarantees the safe in utilization of elevator.

The utility model is achieved in that a kind of no snyed plate block brake, pedestal is relative with moving iron plate, the moving iron plate outside is connected to friction lining, and the toroid winding winding is housed in the pedestal, and institute's improvements are dish-shaped reed or cylindrical helical springs that braking usefulness is housed on the pedestal in the coil winding ring.

The utility model is by changing to pedestal middle part in the coil winding ring with retarding spring from four jiaos of the exterior pedestals of coil winding ring, removed the extrapolation application force of original four jiaos of retarding springs that are provided with to moving iron plate upper/lower terminal, retarding spring is directly affacted with respect to the pedestal at friction lining application of force place middle part, eliminated the diastrophic possibility of moving iron plate thus, so constitute a kind of crooked device of shifting block type drg that do not have.

Advantage of the present utility model, the one, because no flexural deformation, so can directly use the high pure iron material of magneto-conductivity to move iron plate, and the made moving iron plate of pure iron material, volume is little, heating is low, and is stressed even, the operating characteristic that meets magnet stopper, thereby safety control height; The 2nd, because retarding spring is concentrated on the pedestal middle part, after installing adjustable bolt, just can make the adjustment of brake braking force square very convenient, and easy adjustment mode, just can make this selectivity code requirement of " can carry out the lock torque adjustment as required " on every elevator, all be easy to realize at the drg of installing on the elevator, can improve the standard-required of elevator manufacturing and installation thus, make it to become an enforceable codes and standards requirement, so just elevator can be eliminated in the potential safety hazard aspect the drg, thus the safety in utilization of raising elevator.

Fig. 1 is the structural representation of the equipped dish-shaped reed of the utility model.

Fig. 2 is the equipped helical spring structural representation of the utility model.

Fig. 3, Fig. 4 are the structural representations of the equipped two groups of dish reeds of the utility model.

Fig. 5, Fig. 6 are the equipped two groups of helical spring structural representations of the utility model.

The specific embodiment

The shape of the pedestal 1 in the utility model, moving iron plate 2 and friction lining 3 and annexation etc. are all same as the prior art, and the setting of mechanisms such as coil winding 4, cushion blocking 6 also remains unchanged.Dish-shaped reed 5 (Fig. 1) or coil spring 7 (Fig. 2) as retarding spring are housed on the pedestal in coil winding 4 long annular rings.

If described dish-shaped reed 5 is a slice or several pieces to synthetic one group, just can be contained in the center (Fig. 1) of pedestal 1.If described dish-shaped reed 5 is divided into identical two groups of sheet number, just can on pedestal 1, be up and down and distribute, and should be with the axis as symmetrical center line (Fig. 3).If coil winding is the coil winding of two annular arrangements up and down, then two groups of dish reeds 5 just just in time respectively are contained in the ring of a winding.

As shown in Figure 4, the pressing plate 8 of also can packing in the base seat groove after the dish-shaped reed 5 of the utility model on pedestal 1, adjustable bolt 9 penetrates from pedestal 1 outside, withstands on the pressing plate 8.Can realize the adjustment of one group or two groups dish reed lock torque so easily.

If described coil spring 7 is 4-10 one group, just can concentrate in the central channel that is contained in pedestal 1.If described coil spring 7 is divided into identical two groups of number, just can on pedestal 1, be distribute up and down (Fig. 5).

As shown in Figure 6, in the base seat groove of the utility model after every group of coil spring 7 is installed pressing plate 8 is housed, adjustable bolt 9 penetrates from pedestal 1 outside, withstands on the pressing plate 8, can realize unified adjustment of the helical spring lock torque of whole group thus.
