Problems solved by technology

At present, when measuring the deformation of the elevator landing door, it is necessary to use the pressure device to apply pressure to the elevator landing door, and then the operator manually operates the measuring device to measure, and the measurement result cannot be displayed on the display screen
Manual measurement by the operator will inevitably bring about errors inherent in manual operation
The inventor of the present application has developed a device and method for measuring the deformation of elevator landing doors. The reaction force received by the door when the pressure is applied, together with the pressure equipment, a certain slight displacement occurs in the direction away from the elevator landing door (the reason is that the fixed structure undergoes slight deformation under the reaction force), which affects the accuracy of the measurement results

Embodiment Construction

[0048] The method for measuring the deformation of an elevator landing door in the present invention is carried out by using an elevator landing door deformation measuring mechanism.

[0049] like Figure 1 to Figure 12 As shown, the elevator floor door deformation measurement mechanism includes a first fixing device, a second fixing device, an electric push rod mechanism and a laser range finder 1, and the laser range finder 1 is an existing device, and the specific structure is no longer described in detail;

[0050] Take the direction towards the elevator landing door as the forward direction;

[0051] The first fixing device comprises a first hollow crossbeam 2, a first hollow auxiliary beam 3 is slidably inserted in the first hollow crossbeam 2, and the first hollow auxiliary beam 3 protrudes from one end of the first hollow crossbeam 2, and the first hollow auxiliary beam 3 The protruding end and the other end of the first hollow beam 2 are respectively connected with t...

Abstract

The invention discloses a method for measuring the deformation of elevator landing doors. The first step is to transport the elevator landing door deformation measurement mechanism to the elevator landing door to be tested; the second step is to initially install the second fixing device; The first step is to move the second fixing device up and down to the predetermined pressing position in the Y direction; the fourth step is to install the electric push rod mechanism; the fifth step is to install the first fixing device above or below the second fixing device; the sixth step It is to connect the laser range finder and the electric push rod to the external PLC controller respectively to carry out the measurement work. The method is an elevator floor door deformation measurement device capable of eliminating errors caused by manual measurement, and the measurement result will not be affected by the deformation caused by the reaction force.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator landing door deformation measurement mechanism. Background technique [0002] In order to ensure the safe operation of the elevator, the elevator landing door needs to have a certain structural strength, and one of the indicators is the deformation index of the elevator landing door under pressure. Under the same pressure, the smaller the deformation of the elevator landing door, the stronger the elevator landing door is, and it is less likely to be damaged. At present, when measuring the deformation of the elevator landing door, it is necessary for the operator to manually operate the measuring device for measurement after applying pressure to the elevator landing door with a pressure device, and the measurement result cannot be displayed on the display screen. Manual measurement by the operator will inevitably bring about errors inherent in manual operation. The...
