Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Embodiment of the present utility model is described in detail below in conjunction with Fig. 1.
Fig. 1 shows the structural representation of the utility model embodiment.As shown in Figure 1, the utility model provides a kind of safety control system of elevator, and the safety control system of this elevator comprises traction sheave coder 1, counterweight 2, car 3, velocity limiter coder 4, safety governor 5, main rope 6, speed limiter wire rope 7 and gsm module 8.The utility model adopts traction sheave coder 1 and velocity limiter coder 4 Dual-encoder, and Dual-encoder is connected with safety governor 5 by shielded cable, and the code signal that safety governor 5 pairs of traction sheave coders 1 and velocity limiter coder 4 produce is measured.Traction sheave coder 1 is detect towing machine running state in real time, and velocity limiter coder 4 detects cage operation state in real time.Safety governor 5 detects the operation conditions of towing machine 3 and car simultaneously, compares the synchronizing information that both run, and preserves the statistics of synchronizing information, compare, take corresponding safety measure with the setting value of safety governor 5.
Traction sheave coder 1 is connected with the main shaft of the towing machine of elevator, drive when towing machine runs traction sheave coder 1 to rotate and produce code signal output, towing machine running velocity, Distance geometry sense of motion is calculated according to the code signal of traction sheave coder 1, the code signal frequency that towing machine speed faster traction sheave coder 1 produces is higher, and towing machine is rubbed by traction sheave and main rope 6 and drives car 3 up-and-down movement.
Velocity limiter coder 4 is arranged on the flywheel shaft of velocity limiter, velocity limiter is connected with car 3 by speed limiter wire rope 7, car 3 drives the flywheel turns of velocity limiter by speed limiter wire rope 7, thus make velocity limiter coder 4 rotate the output of generation code signal, car 3 moves faster, the code signal frequency that velocity limiter coder 4 exports is higher, directly can determine running velocity, the Distance geometry sense of motion of car 3 according to the code signal of velocity limiter coder 4.
