Problems solved by technology

[0002] In the field of elevator safety technology, the horizontal anti-pinch safety technology for elevator door closing is relatively mature, but the vertical anti-pinch safety technology for elevators is rarely involved. At present, almost all elevators are controlled by programmable controllers. Once the programmable controller controls the internal operation program to make mistakes, it will lead to unpredictable erroneous actions such as the elevator starting before the elevator door is completely closed, and the possibility of accidents such as vertical pinching of passengers by the elevator. Very big

Abstract

The invention relates to a lengthwise anti-clamp device of an elevator. The lengthwise anti-clamp device of the elevator is arranged above an elevator entrance and comprises a beam, lead rails, a spring, a support and an elevator emergency stop switch, the beam is transversely arranged above the elevator entrance, two ends of the beam are respectively arranged on the lead rails, the lead rails are firmly arranged at two sides of the elevator entrance, one end of the spring is arranged at the spring while the other end is arranged on the support, the support is firmly arranged above the beam, and the elevator emergency stop switch is connected with a traction machine power supply of the elevator in series. When there is no external force on the beam, the spring is located at a natural state, when there is external force on the beam, the beam can move upwardly along the lead rails, the elevator emergency stop switch is turned on to enable the elevator to stop running, and at the moment, the spring is located at a compressed state. The lengthwise anti-clamp device of the elevator can protect people who take the elevator from the lengthwise clamping injury of the elevator.

technical field [0001] The invention relates to the technical field of elevator safety, in particular to an elevator longitudinal anti-pinch device. Background technique [0002] In the field of elevator safety technology, the horizontal anti-pinch safety technology for elevator door closing is relatively mature, but the vertical anti-pinch safety technology for elevators is rarely involved. At present, almost all elevators are controlled by programmable controllers. Once the programmable controller controls the internal operation program to make mistakes, it will lead to unpredictable erroneous actions such as the elevator starting before the elevator door is completely closed, and the possibility of accidents such as vertical pinching of passengers by the elevator. Very big. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elevator longitudinal anti-pinch device to prevent elevator passengers from being inju...
