Track trolley system

Abstract

The invention provides an orbital trolley system, wherein a mounting plate (14) is mounted using a groove (9) at the bottom of a running orbit (8) of the orbital trolley within a dustless chamber, and a ground cover board (12) having a plurality of holes (24) is mounted on the mounting plate (14), thus covering a honeycomb hole with the ground cover board easily and reliably.

Description

technical field The present invention relates to a rail trolley system, and in particular to a cover plate covering the floor of a walking space of a rail trolley. Background technique Patent Document 1 (Japanese Patent Application Laid-Open No. 2006-52063) discloses a technique of installing a system with a rail vehicle such as a stacker in a clean room. In a clean room, honeycomb cells (waffles) composed of relatively large cells are sometimes provided on the floor to attract air. When the honeycomb hole is set, it is necessary to cover the honeycomb hole with a cover plate to ensure the safety of the operators who check the track trolley, power supply line, rack, etc. If the cover is only laid on the ground without fixing the cover, it will be very dangerous if the cover falls off. And, if the cover plate is laid before the construction of the track, the unfixed cover plate will hinder the construction of the track. However, if the cover plate is fixed on the ground wi...

AI Technical Summary

Problems solved by technology

If the cover is only laid on the ground and the cover is not fixed, it will be dangerous if the cover falls off

Also, if the cover plate is laid before track construction, the unfixed cover plate will hinder the construction of the track

However, if the cover is fixed to the ground with bolts or the like, the installation of the cover will be laborious
