Abstract
The embedded running wheel brake relates to the technical field of brake. A brake disc (3) is connected with a traction sheave (4) through a bolt, rotating spindles (1) penetrate and are connected in the center holes of the brake disc (3) and the traction sheave (4), one end of the brake disc is provided with a cam (31), and a plurality of symmetrical clamp grooves (311) are arranged on the outside surface of the cam (31) evenly. An operating device (2) is arranged on the corresponding place of the cam (31) of the brake disc (3), a brake block (5) is installed on one end of the operating device (2), a wearing ring (6) is installed on one end of the brake block (5), and copper sheets (7) are installed on the front surface and the rear surface of the brake block (5). The embedded running wheel brake is compact in structure, small in size, convenient to install, low in noise, swift in action, sensitive in response, and safe and reliable in brake.
Description
Technical field:
The utility model relates to the drg technical field, is specifically related to a kind of embedded traction sheave drg.
Background technology:
Drg is to have to make movable parts (or movable machinery) slow down, stop or keeping the device of the functions such as halted state.The mechanical component that make the movement parts in machinery stop or slowing down.Be commonly called as brake, lock.
Drg is the important safety device of elevator, it safe, reliably be one of key factor of guaranteeing elevator safety operation.
There is following shortcoming in existing elevator brake: structure is not compact, and volume is large, and inconvenience is installed, and noise is large, and slow motion is slow in reacting, brakes dangerous, unreliable.
The utility model content:
The purpose of this utility model is to provide a kind of embedded traction sheave drg, its compact conformation, and volume is little, and is easy for installation, and noise is little, and action is fast, is quick on the draw, brake safe, reliable.
in order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises rotating shaft 1, operating control 2, brake disc 3, traction sheave 4, brake disc 3, traction sheave 4 is bolted, and rotating shaft 1 difference cross-under is at brake disc 3, in traction sheave 4 centre holes, one end of brake disc 3 is provided with cam 31, be provided with uniformly several symmetrical draw-in grooves 311 on the outside face of cam 31, operating control 2 is arranged on the corresponding position of the cam 31 of brake disc 3, one end of operating control 2 is equipped with slipper 5, one end of slipper 5 is equipped with flow ring 6, the front surface of slipper 5 and rear surface all are equipped with copper sheet 7.
The wearing face of described flow ring 6 is waveform or knurling.
Be provided with vibration damping sheet between described slipper 5 and copper sheet 7.
Principle of work of the present utility model is: when needs were braked, operating control 2 operations made slipper 5 in the outside face friction of the cam 31 of brake disc 3, brake disc 3 is slowed down, and when slipper 5 runs into draw-in groove 311 on cam 31, slipper 5 will be stuck in draw-in groove 311, thereby realize braking, when needs moved, operating control 2 was retracted, when running into power failure or outage, operating control 2 will stretch out, make brake disc 3 brakings, guarantee its safety, stable.
The utility model compact conformation, volume is little, and is easy for installation, and noise is little, and action is fast, is quick on the draw, brake safe, reliable.
Description of drawings:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the structural representation of brake disc 3 in the utility model.
The specific embodiment:
referring to Fig. 1-Fig. 2, this specific embodiment adopts following technical scheme: it comprises rotating shaft 1, operating control 2, brake disc 3, traction sheave 4, brake disc 3, traction sheave 4 is bolted, and rotating shaft 1 difference cross-under is at brake disc 3, in traction sheave 4 centre holes, one end of brake disc 3 is provided with cam 31, be provided with uniformly several symmetrical draw-in grooves 311 on the outside face of cam 31, operating control 2 is arranged on the corresponding position of the cam 31 of brake disc 3, one end of operating control 2 is equipped with slipper 5, one end of slipper 5 is equipped with flow ring 6, the front surface of slipper 5 and rear surface all are equipped with copper sheet 7.
The wearing face of described flow ring 6 is waveform or knurling.
Be provided with vibration damping sheet between described slipper 5 and copper sheet 7.
The principle of work of this specific embodiment is: when needs were braked, operating control 2 operations made slipper 5 in the outside face friction of the cam 31 of brake disc 3, brake disc 3 is slowed down, and when slipper 5 runs into draw-in groove 311 on cam 31, slipper 5 will be stuck in draw-in groove 311, thereby realize braking, when needs moved, operating control 2 was retracted, when running into power failure or outage, operating control 2 will stretch out, make brake disc 3 brakings, guarantee its safety, stable.
This specific embodiment compact conformation, volume is little, and is easy for installation, and noise is little, and action is fast, is quick on the draw, brake safe, reliable.
