The invention discloses a hydraulic lift car safety protection device which comprises safe pliers, safe plier connectors, a first transmission shaft and a second transmission shaft. The first transmission shaft is fixedly sleeved with a first poking element and a first connector, the second transmission shaft is fixedly sleeved with a second poking element and a second connector, a third connector is arranged between the first connector and the second connector, one end of the third connector is hinged to the free end of the first connector, the other end of the third connector is hinged to the free end of the second connector, the free end of the first poking element is connected with a steel wire rope on a traction lift car in a combined mode through a rope head, the free end of the second poking element is hinged to the safe plier connectors, and the safe plier connectors are fixedly connected with the safe pliers. The hydraulic lift car safety protection device can save lift installation space and reduce cost, and has the advantages of being simple in structure, safe, reliable, low in price and the like. Lifts can be installed in some ultra-small shafts.
Description
technical field [0001] The invention relates to a device for protecting the safe operation of an elevator car, in particular to a safety protection device for a hydraulic elevator car. Background technique [0002] At present, with the rapid development of the national economy and the improvement of people's living standards, the real estate industry has shown a high-speed development situation. Elevators, as vertical transportation tools in buildings, have been widely used in recent years. At present, a safety gear device is provided in the elevator to lock the car on the guide rail when the elevator goes down or goes overspeed, so as to prevent elevator accidents from happening. At present, the elevator safety gear device must be used in conjunction with the speed limiter. The safety gear action is triggered under the control of the speed limiter. When the speed of the elevator exceeds the limit speed set by the elevator speed limiter, the car is emergency stopped and clam...
