Embodiment Construction

[0024] like figure 1 , figure 2 As shown, the subway screen door insulation structure provided by the present invention is arranged between the platform 9 and the threshold 8, and the platform 9 is to the track side (ie figure 2 middle right side) protrudes a platform board 91, the threshold 8 is fixed above the platform board 91, and the upper part of the threshold 8 is provided with a threshold profile 81, which is used for electrical connection with the subway screen door to form an equipotential, so The U-shaped support 82 at the bottom of the threshold 8 is fixed with the platform plate 91 through the penetration bolts 10, which are all prior art. And the present invention also has following unique design:

[0025] In the present invention, an insulating adhesive layer 3 is first coated on the upper surface, the lower surface, and the track side surface of the platform board 91, and the insulating adhesive layer 3 covers the entire length direction of the platform boa...

Abstract

The invention provides a metro shielding door insulation structure. The metro shielding door insulation structure is arranged between a platform and a threshold, wherein a platform plate is protruded from the platform toward a rail side, an insulation glue layer is wrapped around the whole surface of the platform plate, an L-shaped insulation padding plate is arranged on a portion of a U-shaped support of the threshold, connected with the platform plate, an L-shaped insulation support is arranged between the platform plate and a platform side, an insulation glue strip is inlaid between a threshold profile on the upper portion of the threshold and the L-shaped insulation support, a U-shaped support on the lower portion of the threshold is fixed on the platform plate through a penetration bolt, and the penetration bolt is isolated through an upper insulating bush, a lower insulating bush and a bolt protecting bush, and therefore no conductive area generated by pollution exists, and furthermore insulation failure is effectively avoided.

Description

technical field [0001] The invention relates to an insulation structure between the threshold of a subway screen door and the ground. Background technique [0002] The insulation problem of the subway screen door is a problem that has not been effectively solved in the industry for many years. The so-called insulation of the screen door is to realize the insulation between the screen door as a whole and the ground, and at the same time to equipotentialize the train and the return rail. To achieve this effect, the first thing to solve is the effective insulation between the connection between the screen door body (especially the threshold) and the platform board. However, at present, due to the inability to completely achieve effective insulation, most of the measures taken are to paste insulating films on the pillars of the screen door. Although it can avoid the discomfort caused by human body contact, it has not really realized the insulation of the screen door. It is not ...
