Description

Platform door insulation threshold

Technical Field

The utility model relates to an insulation system technical field especially relates to an insulating threshold of platform door.

Background

From the view point of logistics, the platform is the connection point between the line and the warehouse and is the necessary path for the warehouse to enter and exit goods. The platform is used as a vehicle stop, a cargo handling place and a temporary storage place. The platform can be used for conveniently loading goods into the vehicle or taking the goods out of the vehicle, and the limit transfer of the central line and the nodes in the logistics network is realized. Potential difference generated by stray current and static exists among the train, the platform and the platform door, when passengers pass through the platform door and contact the doorsill, the potential difference can generate current, and the generated current can cause discomfort or injury to the passengers. However, the problem that insulation between the shield door and the platform in the industry is troubling engineering technicians is not solved effectively all the time, and the problems that the insulation effect of the platform door insulation threshold is not ideal, the structure of the platform door insulation threshold is not firm enough and can be damaged after long-term use are solved

Therefore, an insulating door sill structure for a platform door, which has a long service life, a good insulating effect, a simple structure and convenient installation, is a goal pursued by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

To the weak point that exists in the above-mentioned problem, the utility model provides an insulating threshold of platform door makes it have insulating effect that can be good, and simple structure, firm, and the supporting effect is good, characteristics such as long service life.

In order to solve the above problem, the utility model provides a technical scheme as follows:

the utility model provides an insulating threshold of platform door, includes threshold base and threshold casing, the threshold base with the threshold casing passes through fixing bolt fixed connection, fixing bolt includes first fixing bolt and second fixing bolt, first fixing bolt sets up the left side of threshold casing, the second fixing bolt sets up the right side of threshold casing.

Furthermore, a groove is formed in the doorsill base, an insulating support is arranged at the upper end of the groove, the shape of the insulating support is matched with that of the groove, and the insulating support is made of a silica gel composite material.

Further, the groove and the insulating support are fixedly connected through a bolt, the bolt is arranged on the left side of the groove, a first gasket is arranged at the joint of the bolt and the groove, a nut is arranged on the right side of the bolt, and a second gasket is arranged at the joint of the nut and the groove.

Further, the groove and the threshold base are of an integrated structure.

Furthermore, an insulating plate is arranged at the lower end of the threshold base and made of epoxy resin materials.

Further, a threshold panel is arranged on the upper surface of the threshold shell, and an anti-skid bulge is arranged on the upper surface of the threshold panel.

Compared with the prior art, the utility model has the advantages of it is following:

1. the doorsill base and the doorsill shell are fixedly connected through the fixing bolts, so that the doorsill is simple in structure and convenient to disassemble and maintain;

2. the doorsill base is provided with a groove, the upper end of the groove is provided with an insulating support, the shape of the insulating support is matched with that of the groove, the doorsill is stressed uniformly, the bearing strength of the doorsill can be improved, the service life of the doorsill is prolonged, and the insulating support is made of a silica gel composite material and has the characteristics of high mechanical strength, shock resistance and good insulating property.
