Gap measuring device for the most unfavorable point of elevator landing door

Abstract

The invention discloses a gap measuring device for the most unfavorable point of an elevator landing door, and belongs to the technical field of elevator detection. The measuring device comprises a lower machine shell, an upper machine shell, a force measuring sensor, a left support, a base, a lead screw, a sliding table, a movable plate and a displacement sensor. The force measuring sensor is fixed in the lower machine shell, the left support is connected with the bottom of the force measuring sensor, the top of the force measuring sensor is connected with the base, the lead screw is rotationally arranged in the lower machine shell and is in threaded connection with the sliding table, the moving plate is fixed to the sliding table, the displacement sensor is arranged in the lower machine shell, and the moving end of the displacement sensor is connected with the sliding table. The problems of errors and unstable measured data caused by unstable force application points of the pull and push dynamometer can be effectively reduced, the measurement accuracy is greatly improved, measurement errors caused by human factors are avoided, the working quality and efficiency are improved, single-person operation is achieved, and the labor intensity of operators and the human input are reduced.

Description

technical field [0001] The invention belongs to the technical field of elevator detection, and in particular relates to a device for measuring the gap at the most unfavorable point of an elevator landing door. Background technique [0002] Traction and forced drive elevators need to undergo supervisory inspection after installation, and then regular inspections are required every year. Whether it is supervisory inspection or regular inspection, it needs to be carried out in accordance with the inspection items and categories in the special equipment safety technical specification (TSG T7001-2009) , of which 6.3 door clearance (2) stipulates: in the opening direction of the active door leaves of horizontally moving doors and folding doors, 150N manpower is applied at the most unfavorable point. Greater than 45mm. [0003] In order to implement (TSG T7001-2009) 6.3 door gap (2), the existing traditional technical means in my country is to use push-pull force gauge to measure,...

Problems solved by technology

[0003] In order to implement (TSG T7001-2009) 6.3 door gap (2), the existing traditional technical means in my country is to use push-pull force gauge to measure, but the installation of the traditional push-pull force gauge is relatively difficult and the operability is very poor. At the same time, at least 2 inspectors, or even 3 inspectors are required to participate in the inspection at the same time. One or two inspectors use two push-pull gauges to push the elevator door to both sides. The display value on the push-pull gauge is At 150N, another inspector uses a steel ruler to measure the door clearance

However, the biggest problem with this measurement method is that the 150N measured by the inspector with the push-pull gauge will continue to change due to the shaking of the human hand, which will lead to changes in the gap value, which not only leads to large errors in the measurement results, but also causes serious problems. It is manpower-intensive, and due to the instability of manual operation, even the same inspector may have different results at different times. Therefore, the traditional measurement method is difficult to meet the measurement requirements, which seriously affects the accuracy of the measurement. sex
