Technical Field

[0001] The utility model belongs to the technical field of elevators and relates to a car top mounting linkage mechanism and an elevator. Background Art

[0002] As a vertical transportation tool for people in high-rise buildings, the safety of elevator operation has also attracted widespread attention. As one of the important safety protection devices of elevators, the elevator speed limiter safety clamp linkage mechanism is used to quickly stop the elevator car on the guide rail and keep it stationary when the elevator is overspeeding, out of control or the suspension device is broken, so as to avoid casualties and equipment damage.

[0003] For example, a utility model patent with application number CN201620749084.3 provides an emergency stop device and an elevator, including a plurality of lower beams, which are arranged in the front-to-rear direction of the lifting passage at the lower part of the car that is lifted and lowered in the lifting passage, and are respectively parallel to the opposing directions of the left and right guide rails oppositely arranged in the lifting passage; a pair of wedge brakes, which are arranged below these lower beams; an emergency stop device body, which presses the pair of wedge brakes to the guide rails; and a wedge receiving part, which has a bottom surface that collides with the pair of wedge brakes from the emergency stop device body and an upper surface on which one or more plates with a plate width in the front-to-rear direction are arranged in the opposing direction.

[0004] In summary, although some existing technical solutions have solved the safety problem of elevator overspeed, the speed limiter is directly connected to the safety clamp, which is prone to malfunction during the elevator's downward movement, causing the elevator to stop running unexpectedly, and there is much room for improvement.

[0014] In the above-mentioned car roof mounting linkage mechanism, the fixing hole is provided with a first threaded portion, the fixing pin is provided with a second threaded portion, and the fixing pin can be connected to the first threaded portion of the fixing hole through the second threaded portion.

[0015] In the above-mentioned car roof installation linkage mechanism, it also includes a straight beam, and the linkage component and the safety clamp are connected through the straight beam.

[0016] In the above-mentioned car roof installation linkage mechanism, it also includes a micro switch and a switch touch plate, the micro switch is connected to the straight beam, the micro switch is used to be electrically connected to the controller and transmit signals to the controller, the switch touch plate is connected to the linkage rod, and the switch touch plate can contact the micro switch.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. By installing the linkage mechanism on the car top, when the elevator is overspeeding, the speed limiter wire rope of the elevator needs to overcome the elastic force of the support spring when it is pulled upward to pull the safety clamp pull bar to make the safety clamp actuate. Therefore, it is not easy to cause misoperation during the elevator going down, etc., which solves the safety problem of the elevator when it is overspeeding.

[0022] 2. When the trigger element drives the linkage rod to rotate, the stay spring is deformed under the action of the linkage rod and the spring mounting seat. The torque of the stay spring can be adjusted by changing the connection between the adjustment part of the stay spring and the spring mounting seat.

[0023] 3. When the linkage rod rotates and the safety clamp clamps the guide rail to decelerate the elevator, the switch touch plate on the pull rod contacts the micro switch on the straight beam during the rotation of the pull rod. At this time, a signal is transmitted to the controller to stop the trigger element from continuing to drive the linkage rod to rotate. BRIEF DESCRIPTION OF THE DRAWINGS
