The specific embodiment
In order to understand the utility model better, be described further below in conjunction with drawings and Examples, referring to Fig. 1 to Fig. 5:
The rotary braking device of the backspin tower crane of implementing according to the utility model, be installed on the body 15 of swing type mechanism, it comprises by brake wheel 2, brake shoe brake cheek 3, lever assembly, retarding spring 5 and electronic fluid power push rod 11 and forming, brake wheel 2 is round-shaped and is connected on the rotary main shaft 1, brake wheel 2 circumference outsourcing windings are equipped with brake shoe brake cheek 3, brake shoe brake cheek 3 is connected with the mouth of lever assembly, and the input end of lever assembly is connected by the electronic fluid power push rod 11 that a handspike bearing 13 and an end are fixed on the body 15.
The arcuate structure that brake shoe brake cheek 3 is made by the higher material of damping friction coefficient, glancing impact start brake shoe brake cheek 3 and hold brake wheel 2 generation damping friction moments tightly.In order to make rotary main shaft 1 stressed balance more, brake shoe brake cheek 3 adopts symmetrically arranged upper and lower brake shoe form, lever assembly also correspondingly includes upper lever 4, rod assembly 9, following lever 12 and set square 10,4 terminal connections of upper lever are gone up brake shoe, the following lever 12 terminal brake shoes down that connect.Three end points of set square 10 are hinged electronic fluid power push rod 11, following lever 12, rod assembly 9 respectively, rod assembly 9 other ends connect upper lever 4, shown in Fig. 6,7, described rod assembly 9 is the length-adjustable rod assembly 9 that positive left-hand thread screw mandrel 92 and screw thread joint element for bar 91 cooperate connection to form, so that adjust the stroke of the electronic fluid power push rod 11 of glancing impact, and brake shoe brake cheek 3 and brake wheel 2 initial separation are adjusted in brake shoe brake cheek 3 wearing and tearing backs.Upper lever 4, following lever 12 are by on the lever support 14 hinged bodies 15, and hinge-point is arranged between electronic fluid power push rod 11 and the brake shoe brake cheek 3.Upper lever 4 runs through with following lever 12 and is provided with retarding spring adjusting screw(rod) 6, on the retarding spring adjusting screw(rod) 6 between upper lever 4 and the following lever 12 retarding spring 5 is set.Regulate the lock torque that retarding spring adjusting screw(rod) 6 scalable brake shoe brake cheek 3 and brake wheel 2 binding forces produce.
The power supply parallel connection of the circuit of electronic fluid power push rod 11 and turning motor, and electronic fluid power push rod 11 is unidirectional damping adjustable push rod, the electric energy undamped is released fast, dead electricity has damping to regain at a slow speed.Electronic fluid power push rod 11 must electric release drive upper lever 4, play lever 12 to make upper and lower brake shoe take-off the brake drum 2 around the frame rotation simultaneously when the platform turning motor was worked like this.When turning motor stopped, electronic fluid power push rod 11 dead electricity were regained, and retarding spring 5 opens under the elastic force effect, and retarding spring 5 promotes upper and lower lever 12 simultaneously, makes brake shoe brake cheek 3 combine braking with brake wheel 2.Adjust the backhaul damping intensity of electronic fluid power push rod 11, can also control brake hoof piece and brake wheel 2 by the time that is separated to combination.
Manual push-pull rod component 8 is set in the time of autobrake, makes device have the function of normally closed braking characteristics of failure-free and manually opened closure, lever assembly is connected with manual push-pull rod component 8.Manually push-pull rod component 8 is connected with upper lever 4, and as Fig. 8: manual push-pull rod component 8 comprises pull bar and stop tab 7 up and down, and pull bar runs through upper lever 4, and stop tab 7 is connected to the pull bar of upper lever 4 upper and lower surface locations up and down, a position-limiting action.
The working process of present embodiment is: brake shoe brake cheek separates automatically with brake wheel, and as shown in Figure 1, when turning motor got the electrical mechanisms revolution, because also thereupon link in parallel with turning motor of drg opened, electronic fluid power push rod 11 got.Electronic fluid power push rod 11 is released fast, and promoting lever assembly by set square 10 is upper lever 4, following lever 12, by lever assembly compression brake spring 5, and makes brake shoe brake cheek 3 separate with brake wheel 2.
Brake shoe brake cheek combines with brake wheel is automatic, as shown in Figure 2, in the time of the turning motor outage, electronic fluid power push rod 11 outages.Electronic fluid power push rod 11 is regained, because the dumping force of electronic fluid power push rod 11 slowly opens retarding spring 5, the promotion upper lever 4 and the following lever 12 of retarding spring 5 make brake shoe brake cheek 3 combine with brake wheel 2.Realize arrester close.Regulate the lock torque that retarding spring adjusting screw(rod) 6 scalable brake shoe brake cheek 3 and brake wheel 2 binding forces produce.And adjust the backhaul damping intensity of electronic fluid power push rod 11, can also control brake hoof piece and brake wheel 2 by the time that is separated to combination.
Brake shoe brake cheek and brake wheel manual separation are seen accompanying drawing 3: under the state of drg braking, inwardly twist the handwheel of manual push-pull rod component 8, by stop sheet 7 promotion upper levers 4 can compression brake spring 5 manual release the brakes up and down.
Brake shoe brake cheek combines with brake wheel is manual, sees accompanying drawing 4: outwards twist the handwheel of manual push-pull rod component 8, promote upper levers 4 by stop sheet 7 up and down and can be further closed drg together with retarding spring 5.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
