Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent.
In order to more succinct explanation the present embodiment, at accompanying drawing or in illustrating, the known but component incoherent with the main contents of this patent of some the art those of ordinary skill can be omitted.In addition, in order to interpreting blueprints of being more convenient for, in accompanying drawing, some component has amplification, reduces and part omission, but does not represent size or the entire infrastructure of actual product; When not affecting interpreting blueprints and can not producing ambiguity, some component may not chart by National Standard of Mechanical Drawing.
Embodiment:
As shown in Figure 1, a kind of braking device of hoist machine, comprise circular brake disc 1, brake disc 1 is arranged on the motor output shaft 2 of hoist machine, and the dead in line of the axis of brake disc 1 and motor output shaft 2; The both sides of brake disc 1 are respectively provided with a brake shoe 3, two brake shoes 3 and are symmetrically distributed in brake disc 1 both sides; Brake shoe 3 is arranged on brake arm 4, the lower end of brake arm 4 is hinged on the support 6 of hoist machine by horizontal bearing pin 5, upper end is socketed on the piston rod 71 of a two-way hydraulic cylinder, piston rod 71 is substantially horizontal, and two-way hydraulic cylinder 7 can drive brake arm 4 to be basic point with horizontal bearing pin 5, to swing along the radial direction of brake disc 1.
There is piston rod at the two ends of two-way hydraulic cylinder 7, can be simultaneously protruding or inwardly retract.The principle of braking is: brake shoe is normally closed, and before also not doing any operation, brake shoe is in braking state, and namely motor cannot rotate; When needs starting electrical machinery, operation respective switch, first can start two-way hydraulic cylinder, brake shoe unclamps by two-way hydraulic cylinder, and motor just can start.
Brake shoe 3 is arranged on brake arm 4, and the lower end of brake arm is hinged, and upper end is connected to piston rod, and piston rod stretches, and brake arm just can be allowed to swing, also just can unclamp or brake.
Because brake shoe 3 is at the middle part of brake arm, and piston rod 71 is in the upper end of brake arm, so braking and unclamping is all a laborsaving lever, saves power consumption.
Wherein, the outside of the upper end of brake arm 4 is provided with guide rod 8, and guide rod in the below of piston rod, and is parallel to piston rod, and brake arm is set on guide rod, and brake arm is provided with and the waist shaped hole of matching guide bars (not illustrating in the drawings).The swing of such brake arm can not be inclined, because the track swung is an arc, so brake arm is provided with waist shaped hole (connection of certain piston rod and brake arm is also with certain flexibility).
Wherein, guide rod outer end is provided with back-up ring 81, the guide rod between back-up ring and brake arm is arranged with Compress Spring 82.The effect of Compress Spring allows the brake arm after unclamping " automatically " brake, and keeps normally off.
Wherein, be provided with adjusting nut 83 outside back-up ring, adjusting nut can regulate the position of back-up ring.Like this can adjustable brake strength.
Wherein, brake shoe 3 is the arc mated with brake disc towards the side of brake disc.Such brake shoe is better with coordinating of brake disc, is not easy wearing and tearing.
Wherein, the arc surface of brake shoe 3 is provided with brake friction material (not illustrating in the drawings), and the circumferential surface of brake disc is processed with the grid annular knurl (not illustrating in the drawings) of regulation order number.Such frictional force is larger, and braking ability is better.Brake friction material is exactly some conventional brake friction materials, need not describe.
In the above-described embodiments, the braking device of a kind of hoist machine that the utility model provides, comprise circular brake disc, brake disc is arranged on the motor output shaft of hoist machine, and the dead in line of the axis of brake disc and motor output shaft; The both sides of brake disc are respectively provided with a brake shoe, brake shoe is arranged on brake arm, the lower end of brake arm is hinged on the support of hoist machine by horizontal bearing pin, upper end is socketed on the piston rod of a two-way hydraulic cylinder, and two-way hydraulic cylinder can drive brake arm to be basic point with horizontal bearing pin, to swing (namely brake or unclamp) along the radial direction of brake disc.Its beneficial effect is: structure is simple, and cost is low, easy to maintenance.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
