Background
The elevator landing door is an important part for ensuring the safety of passengers, and the transition and isolation of the elevator and a building are realized by the elevator landing door, so that relatively closed isolation protection is formed between an elevator well and a building channel, and accidents caused by falling of personnel into the well are prevented.
In recent years, the safety accidents that people outside the landing door accidentally drop into the elevator shaft occur many times at home and abroad, and most of reasons for the safety accidents are that the landing door is impacted by external horizontal acting force, so that the landing door leaf deforms or the guide shoes are separated from the sliding grooves, and the landing door leaf displaces and forms a gap with a building. According to the structural analysis of the elevator landing door, when the elevator landing door is impacted by horizontal or approximately horizontal external force, the door leaf generates reaction force through the mechanical strength of the door leaf, the upper guide device and the lower guide shoe thereof so as to keep the landing door stable at the working position, and most of the external force acts on the lower part of the door leaf; therefore, the depth of engagement of the guide shoe appears to be critical.
Therefore, when the elevator is subjected to daily maintenance, self-inspection, supervision inspection and periodic inspection, the engagement depth of the landing door guide shoe is measured, but because the sill chute is narrow, the engagement position of the elevator landing door guide shoe and the sill chute is deeper, if a contact measurement mode is adopted, even if the elevator car is operated in an overhaul state, and the elevator car stands on a car top overhaul platform for measurement, the elevator landing door guide shoe cannot be conveniently and rapidly measured directly due to narrow space.

Further, in order to improve the measuring range and the measuring accuracy, the support is moved in the vertical direction.
Further, in order to control lifting of the support, the shell is connected with a screw in a threaded mode, the lower end of the screw is connected with a bearing seat on the support, and the upper end of the screw is connected with a handle above the shell.
Further, in order to promote the stability that the support removed, the measuring personnel of being convenient for simultaneously know the distance of support in the removal of vertical direction, the support upper end is provided with the guide pillar that vertically stretches out the casing, is provided with the scale on the guide pillar lateral wall.
Further, a reference plate which is flush with the lower end face of the shell is arranged on one side of the shell, so that the contact area between the shell and the upper end face of the sill is enlarged, and the stable placement of the shell is ensured.
The utility model has the beneficial effects that: when the engagement depth of the guide shoe extending into the sliding groove is required to be measured, a measurer opens the cover plate upwards, then extends the measuring module and the protective cover into the sliding groove of the sill, and carries out non-contact measurement on the engagement depth of the guide shoe through the measuring module so as to improve the convenience and efficiency of detection; meanwhile, when measurement is not needed, the cover plate is turned downwards, so that the measurement module is protected in a space surrounded by the cover plate and the protective cover, and the measurement module is not easy to damage.
