Problems solved by technology

In addition, since a cavity is generated between the storage portion and the upper surface of the well pit, the strength of the upper surface portion of the well pit above the storage portion is reduced.
[0009] In other words, in the technology of Patent Document 1, there are problems such as complicated structure, unstable operation, expansion of well tank volume, and lower strength of the upper surface of the well tank.

Embodiment approach 2

[0098] In this embodiment, as in Embodiment 1, a movable well cover system capable of closing the opening formed in the upper surface portion of the well pit 20 is provided. In this embodiment, there are a plurality of vertically arranged well cover pieces 2 that can be arranged vertically along the inner direction of the well 20 from the position of the upper surface of the well 20 (the position of the floor 30 ). In addition, a first well cover moving device capable of moving the vertically arranged well cover sheet 2 in the vertical direction is provided. In addition, there is a second well cover moving device that can push out the vertically arranged well cover sheet 2 located at the uppermost part in the horizontal direction to block the opening.

[0099] In addition, when sending out to the ground 30 in order to close the opening formed on the ground 30 with the vertically arranged well cover 2 accommodated in the well 20 , the operation of the well cover system accordin...

Abstract

A pit cover system according to the present invention is a mobile pit cover system capable of closing an opening in the upper surface portion of a pit (20). This pit cover system is provided with, in the pit, a plurality of vertical-disposition pit cover pieces (2) capable of being disposed vertically, a first pit cover movement device (15) capable of vertically moving the vertical-disposition pit cover pieces (2), and a second pit cover movement device (16) capable of horizontally pushing out the uppermost vertical-disposition pit cover piece (2) so as to cover the opening.

Description

technical field [0001] The present invention relates to a movable well cover system capable of closing an opening provided on an upper surface of a well, and is applicable, for example, to a well in which a chassis dynamometer device is provided. Background technique [0002] Generally, the chassis dynamometer device is housed in a well, and an opening is arranged on the upper surface of the well. Part of the roller on which the wheel of the automobile to be tested is mounted is exposed from the opening. As a movable type well cover capable of closing the opening, there is a well cover disclosed in Patent Document 1, for example. [0003] In the technique disclosed in Patent Document 1, a plurality of unit well covers are connected via engaging members, and guide rollers that rotate on guide rails are provided on the respective unit well covers. One end of the guide rail is formed as an inclined portion, and is extended to a storage portion provided in the well pit, and th...
