The invention relates to a two-way safety gear system for preventing a lift car from accidentally moving in the opening state of an elevator door. The two-way safety gear system is provided with a gear body and a V-shaped gear block, wherein a V-shaped gap is formed in the gear body, and the V-shaped gear block is arranged in the gear body; a lifting bolt is fastened with the V-shaped gear block, two oblique-pulling bolts respectively pass through two flat head bolts, one end of each of two oblique-pulling springs is respectively connected with the two oblique-pulling bolts, and the other ends of the two oblique-pulling springs are connected with the lifting bolt; normally closed travel switches are arranged on the gear body, and switch touch panels are respectively arranged relative to the positions of the normally closed travel switches; a lifting rod which is connected with a steel wire rope of an elevator speed limiter is arranged on the V-shaped gear block, an electromagnet is arranged in the middle of the left side surface of the V-shaped gear block, an elevator guide rail passes through a clearance between the V-shaped gear block and the gear body, a normally closed travel switch is arranged in a position where an upper sill of the elevator door is closed in position, a switch touch panel is arranged on the upper surface of a door hanging plate, and the normally closed travel switch can be effectively triggered by the switch touch panel when the door is closed in position. The two-way safety gear system has the advantages of unique design, simple structure, low cost and short stopping distance and stopping time, and the system can be directly installed on the basis that an original safety gear of an elevator is not removed.
Description
technical field [0001] The invention relates to a lifting device, especially to the technical field of safety of the lifting device, in particular to a two-way safety gear system that prevents the car from moving unexpectedly when the elevator door is open. Background technique [0002] In today's society, elevators have become an indispensable means of transportation in people's daily life, and the safe operation of elevators is directly related to the safety of people's lives and property. When the elevator is in the open state, the accidental movement of the car is the chief culprit that causes people and goods to be cut, and what’s more, it will fall into the elevator shaft, and the consequences are horrific. So far, although there are some measures to prevent accidental movement of the elevator car, there are problems such as complex structure, high cost, long braking distance and time for braking and stopping, poor pertinence, and inapplicability to old elevators. Str...
