The common door slider structure is middle mounting panel, and the package is moulded rubber on the mounting panel, and rubber has the damping amortization effect, also has certain elasticity, can push through the too narrow cross-section of sill, because rubber itself is not wear-resisting and rubber and sill complex coefficient of friction is big, so wrap up wear-resisting material (wear-resisting and coefficient of friction little material such as teflon or nylon) again on the rubber surface to reduce the frictional force that produces when the bottom of the door moves.
Due to the reasons of the elevator door being not adjusted in place and the like, the door sliding block can be prevented from falling to the center of the sill groove and can lean and extrude towards one side of the sill groove, and under the influence of the counterforce of the inner wall of the sill groove, the friction force is increased rapidly, so that the wear-resistant material on the surface of the door sliding block is worn too fast. Once the wear-resistant material in door slider surface wears out, the wearing and tearing speed of rubber is faster, and the coefficient of friction of rubber and sill will be greater than the coefficient of friction of wear-resistant material and sill moreover, and bottom frictional force increases suddenly when can resulting in the door motion like this, not only produces the noise, still can produce the turnover of door, can cause even on the layer door to force the door closing device can't close the condition that puts in place with the layer door, produces the danger that personnel fall the well.
Therefore, a monitoring means is needed, which can detect that danger is about to appear before the wear-resistant material on the surface of the door sliding block is worn out, and timely replace the door sliding block, and even detect whether the adjustment of the door sliding block is normal by a machine, instead of waiting for the danger to occur, and replacing the door sliding block after the accident occurs.
