Abstract

The invention discloses a mechanical elevator stopping device which comprises a triggering device fixed to a cage frame and a bearing device fixed to a cage guide rail. The triggering device comprises an electric push rod support. An electric push rod is arranged on the electric push rod support. A bearing rod support is arranged beside the electric push rod support. A bearing rod is arranged on the bearing rod support. The electric push rod is connected with the bearing rod. The electric push rod support and the bearing rod support are fixed to the cage frame. The triggering device further comprises a position switch. The bearing device comprises a movement stopping plate opposite to the bearing rod. The movement stopping plate is fixed to the cage guide rail through a fixing device and provided with a vertical U-shaped groove matched with the bearing rod. A safety triggering device is arranged beside the U-shaped groove. The mechanical elevator stopping device has the advantages of being high in efficiency and good in stopping effect.

Description

technical field [0001] The invention relates to an up and down automatic preventing device for elevator inspection and maintenance. Background technique [0002] Elevators are special equipment. It is necessary to strictly abide by the safe operating procedures for their maintenance, and it is necessary to confirm that all safety measures are in normal state before maintenance. Machine-room-less elevators and home elevators need a mechanical stop device to prevent the car from rushing to the top or falling due to the low top station or low pit during maintenance. In addition, when the loading and leveling accuracy of the freight elevator exceeds 20mm, a mechanical device is also required to limit the downward movement of the car. Most of the existing mechanical blocking devices for elevator maintenance are manually used, and the displacement of the car is prevented by clamping the car guide rail like a clamp. This device has the problems of low efficiency and poor blocking ...
