The difference between high-speed and ordinary DazenElevator equipment:
1. Reduction box
The utility model relates to a worm gear reduction box, which is used as a reduction device of an ordinary low-speed elevator, and a helical gear or a planetary reducer is used as a middle speed elevator device. 2 speed limiter
Elevator rated speed is not greater than 0.63m/s, the use of rigid rope speed limiting device, equipped with instantaneous safety tongs. The elevator with rated speed greater than 1m/s is equipped with an elastic slip rope speed limiter and a progressive safety clamp.
3 speed limiter speed
(1) non slip roller instantaneous safety tong is 1.0m/s;
(2) the instantaneous safety caliper is 0.8m/s except for the non slip roller safety tongs;
(3) progressive safety pliers V rated speed is less than or equal to 1.0m/s for 1.5m/s;
(4) progressive safety tongs with rated speed > 1.0m/s > V (1.25V+0.25/V) m/s.
4 、 safety tongs
(1) instantaneous safety gear is often used to lift the rated speed 0.63m/s V > 1m/s;
(2) progressive safety tongs are usually used on elevators with rated speed V > 1.0m/s.
5 、 balance compensation device
(1) low speed, fast lift (elevator speed V = 1.75m/s) by silencing rope compensation chain;
(2) quick lift (elevator speed V=2.5m/s) adopts full plastic balance compensation chain;
(3) high speed elevator (elevator speed V > 2.5m/s) adopts compensating rope with tensioning device;
(4) lift speed V greater than or equal to 3.5m/s, in addition to the above device, also added a tensioning antibouncer.
