るものである。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a lift vehicle that conveys cargo to higher floors such as high-rise apartments and high-rise apartments, and particularly an extension member that extends from a trolley. The present invention relates to a guide rail wall surface contact device for a lift vehicle that indicates that the vehicle has surely contacted a wall surface or the like.
高層建築物の建設に伴って、そうした高速建築物に対す
る貨物の搬入、搬出手段もかつての人力中心から、次第
に機械化導入が進み、現在ではリフト車の開発がなされ
主導的な地位を確率するに至っている。With the construction of high-rise buildings, the introduction of mechanization gradually advanced from the former human power center for the loading and unloading means of freight to such high-speed buildings, and nowadays lift trucks have been developed and have taken the lead position. There is.
ところで、従来のそうしたリフト車は、台車上に装備し

していると言えるが、ガイドレールが壁面等に確実に接
触したことを表示するための表示手段が設けられていな
いために、作業に際し、ガイドレールが壁面等へ接触し
たことを確認する唯一の手段は、地上にいるオペレータ
の目視による確認か、ガイドレールを臨ませる高層階に
て待機している補助者の目視による確認に頼っているの
が実情である。By the way, in such a conventional lift truck, a turntable mounted on a truck is provided with an extending member (guide rail) that is undulating and expandable, and a bucket (carrying box) is moved up and down along the guide rail to a predetermined position. It can be said that the purpose of introducing mechanization has been sufficiently achieved because the cargo is configured to be carried in and out of the destination floor, but a display means is provided to indicate that the guide rail has surely contacted the wall surface, etc. Since it has not been installed, the only way to confirm that the guide rail has come into contact with the wall surface, etc., is by visual inspection by the operator on the ground or by an assistant waiting on the upper floors facing the guide rail. The reality is that people rely on visual confirmation.
従って、ガイドレールが壁面等に確実に接触していない
にもかかわらず、誤って接触したものと判断して貨物の
搬入、搬出作業を開始することがしばしば有り、従って
思わぬ事故を招き非常に危険であり、ガイドレールの壁
面への接触を確実に検出することの出来る簡易な装置の
開発が待たれているのが現状である。Therefore, even though the guide rail is not in contact with the wall surface, etc., it is often judged that the guide rail is in contact with the wall by mistake, and the work of loading and unloading cargo is often started, resulting in an unexpected accident. At present, the development of a simple device that is dangerous and that can reliably detect the contact of the guide rail with the wall surface is awaited.
