Zusammenfassung: | To provide a shaft earth removal device that can be used for a shaft installed in a narrow place in the mountains or on a slope.SOLUTION: The present invention provides a shaft earth removal device that includes an earth removal lift 10 that moves up and down within a shaft A, and a rail section 20 that guides the earth removal lift 10. The rail section 20 includes a pair of left and right rack rails 2 and a support section 30 that supports the rack rails 2. The earth removal lift 10 includes a pair of left and right traveling mechanisms 1 that travel on rack rails 2, a drive device 3 that drives the traveling mechanisms 1, and a bucket 4 that stores excavated soil B. The pair of rack rails 2,2 comprises a vertical rail 21 installed vertically along a peripheral wall of shaft A, a bending rail 22 that is provided continuously on the upper side of the vertical rail 21 and whose upper end side curves outward in the radial direction of the shaft above the opening of the shaft, and an inclined rail 23 that is continuously provided on the upper side of the bent rail 22 and becomes higher in a straight line toward the upper end side.SELECTED DRAWING: Figure 1
【課題】山間の狭小な場所や傾斜地に設ける立坑に用いることができる立坑排土装置を提供する。【解決手段】本発明は、立坑A内を昇降する排土リフト10と、排土リフト10を案内するレール部20とを備える立坑排土装置である。レール部20は、左右一対のラックレール2と、ラックレール2を支持する支持部30とを備える。排土リフト10は、ラックレール2上を走行する左右一対の走行機構1と、走行機構1を駆動する駆動装置3と、掘削土Bを収容するバケット4とを有している。一対のラックレール2,2は、立坑Aの周壁に沿って垂設される鉛直レール21と、鉛直レール21に上側に連続して設けられ、上端側が立坑の開口部の上方において立坑の径方向外方へ湾曲する曲げレール22と、曲げレール22の上側に連続して設けられるとともに上端側に向かって直線状に高くなる傾斜レール23とを備える。【選択図】図1 |
