Portable lift door plate opening force testing instrument

Abstract

The invention discloses a portable lift door plate opening force testing instrument. The portable lift door plate opening force testing instrument comprises a strutting device, a driving mechanism and a force sensor, wherein the strutting device is used for opening left and right lift doors; the driving mechanism is connected with the strutting device to drive the strutting device to be opened or closed; the force sensor is electrically connected with a control system; the force sensor is arranged between the strutting device and the driving mechanism to detect the pressure applied to the lift doors by the strutting device and drive the strutting device to apply a certain force to the lift doors; and the force sensor detects the magnitude of force and inputs the magnitude of force in a control system to be displayed, and a worker can acquire the magnitude of force clearly and accurately, observes the opening condition of the lift doors and whether the lift doors derail or not and determines the safety performance of the lift doors. The portable lift door plate opening force testing instrument is simple in structure, convenient to operate, few in parts and convenient to carry.

Description

technical field [0001] The invention relates to a detection device, in particular to an elevator door panel opening force tester. Background technique [0002] Nowadays, elevators are installed on all floors to facilitate people's travel, and the safety hazards of elevators have been exposed to people one after another, which has become one of the important issues that people must pay attention to. [0003] The inspection department has also strengthened the safety inspection of elevators and issued a series of safety parameter inspection requirements. Manufacturers must carry out safety inspections on elevators in accordance with the requirements to ensure the safety factor of elevators. The opening force of the elevator door (that is, whether the elevator door will be easily opened under the action of external force) is one of the key factors for whether the elevator can run safely, but there is no special detection equipment for the time being. At the same time, in the f...

Problems solved by technology

The opening force of the elevator door (that is, whether the elevator door will be easily opened under the action of external force) is one of the key factors for whether the elevator can run safely, but there is no special detection equipment for the time being. At the same time, in the factory, most of the testing equipment has a complex structure and a large volume. When testing the elevator outdoors, it is impossible to carry the testing equipment outdoors for testing.
