Embodiment Construction
[0021] In order to make the present invention more obvious and understandable, the detailed description is as follows in conjunction with the accompanying drawings.
[0022] Such as figure 1 As shown, a safety gear for elevators includes a fixed plate 1, a first safety device 2, a second safety device 201, two hook shaft fixing seats 3, a hook shaft 4, a spring hook 5 and a flywheel mechanism 6. The fixing plate 1 is U-shaped, and the middle parts of both sides of the fixing plate 1 are connected by spring pull rods 101 . Enhanced support performance, improve firmness. The first safety device 2 and the second safety device 201 are arranged on both sides of the fixed plate 1 respectively, and cooperate with the guide rails on both sides, and the locking is completed through the first safety device 2 and the second safety device 201 . The two hook fixing bases 3 are arranged below the connecting cross bar 271 , and the two hook fixing bases 3 are connected by the hook shaft 4 ...

The invention relates to the technical field of elevators. A safety clamp for a lifting elevator comprises a fixing plate, a first safety device, a second safety device, two hook shaft fixing seats, ahook shaft, an elastic hook and a flywheel mechanism. The middle portions of the two sides of the fixing plate are connected through a spring pull rod. The first safety device and the second safety device are arranged on the two sides of the fixing plate and are matched with guide rails on the two sides, and locking is completed through the first safety device and the second safety device. Two hook fixing seats are arranged below a connecting cross rod and are connected through the hook shaft. The elastic hook is hinged to the hook shaft, can rotate on the hook shaft, and is in a U-type shape. A hook of the elastic hook faces backwards, and a hook notch is formed in the bottom of the elastic hook. The flywheel mechanism is arranged below the elastic hook and is matched with the elastic hook to complete locking. The safety clamp for a lifting elevator has the beneficial effects that the locking speed is adjustable, the centrifugal function is added, and the braking effect and the safety performance are improved.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to a safety gear for elevators. Background technique [0002] Safety gear is an important safety component of elevator equipment, which can play an important role in safety guarantee when the elevator is overspeed and out of control. means of transport. The safety gear device is a safety device that stops the car in an emergency and clamps it on the guide rail under the control of the speed governor. The action of the safety gear device is to make the rope clamp clamp the speed limiter rope through the action of the speed limiter. As the car runs downward, the speed limiter rope pulls the safety gear linkage mechanism, and the safety gear linkage mechanism moves to drive The braking element of the safety gear is in contact with the guide rail, so that the safety gear on both sides of the guide rail is clamped on the guide rail at the same time, so that the car is stopped. It pr...
