Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 2 to Fig. 5.Elevator internal contracting brake of the present utility model, comprise drg 1, push rod 4, the first band-type brake arm 2 and the second band-type brake arm 3, the first band-type brake arm 2 and the second band-type brake arm 3 lay respectively at the both sides of drg 1, push rod 4 is located between the first band-type brake arm 2 and the second band-type brake arm 3, push rod 4 props up the first band-type brake arm 2 and the second band-type brake arm 3, and push rod 4 is connected with the top of the second band-type brake arm 3 with the first band-type brake arm 2.In order to meet different user demands, can be between the first band-type brake arm 2 and push rod 4, and second be all provided with pipe link between band-type brake arm 3 and push rod 4, make two ends butt the first band-type brake arm 2 and the push rod 4 respectively of the pipe link between the first band-type brake arm 2 and push rod 4, the two ends of the pipe link between the second band-type brake arm 3 and push rod 4 are butt the second band-type brake arm 3 and push rod 4 respectively, facilitates the power on push rod 4 can act on the first band-type brake arm 2 and the second band-type brake arm 3.Push rod 4 is armature push rod, and armature push rod is two, and two armature push rods are between the first band-type brake arm 2 and drg 1, and between the second band-type brake arm 3 and drg 1.
The bottom that the outside of the first band-type brake arm 2 and the second band-type brake arm 3 is separately installed with spring 5, the first band-type brake arms 2 and the second band-type brake arm 3 is equipped with eccentric shaft 6, the first band-type brake arms 2 and the second band-type brake arm 3 is located at the both sides of band-type brake wheel 7.In use, band-type brake wheel 7 is arranged on support 10, eccentric shaft 6 passes the first band-type brake arm 2 and the second band-type brake arm 3 and is fixed on support 10.
When drg 1 is switched on, drg 1 promotes the first band-type brake arm 2 and the second band-type brake arm 3 respectively by armature push rod to both sides, and the first band-type brake arm 2 and the second band-type brake arm 3 rotate respectively centered by the eccentric shaft 6 of bottom; Simultaneously, owing to being provided with eccentric shaft 6, thereby, can adjust the height that eccentric shaft 6 changes the vertical direction of the first band-type brake arm 2 and the second band-type brake arm 3, when the first band-type brake arm 2 and the second band-type brake arm 3 are laterally rotated, the height of vertical direction reduces, and band-type brake wheel 7 declines relatively, unclamp the braking to band-type brake wheel 7, elevator drive towing machine can start operation.Along with the outside rotation of the first band-type brake arm 2 and the second band-type brake arm 3, the spring 5 in the first band-type brake arm 2 and the second band-type brake arm 3 outsides is compressed gradually, makes spring 5 in compressive state.
When after drg 1 power-off, the thrust of the armature push rod of drg 1 disappears, the first band-type brake arm 2 and the second band-type brake arm 3 are under the effect of the bounce of spring 5, centered by eccentric shaft 6, turn to the inside, simultaneously, adjusting eccentric shaft 6 increases the vertical height of the first band-type brake arm 2 and the second band-type brake arm 3, rise with respect to band-type brake wheel 7, increase the area of contact of the first band-type brake arm 2 and the second band-type brake arm 3 and band-type brake wheel 7, under the effect of the bounce of spring 5, until band-type brake wheel 7 is held tightly, realize braking, elevator drive towing machine is in braking mode.
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, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
