To prevent a contact member from slipping against a vertical bar member to ensure that a material carrier is prevented from falling, when attaching a fall prevention mechanism to an unloading device.SOLUTION: An unloading device comprises an adjustment box 10 that moves up and down along a first guide pipe 50 having a circular cross section, and a material carrier 40 connected to the adjustment box 10. The adjustment box 10 comprises a box frame with a top plate, a lifting body 20 that slides up and down on the circumference of the first guide pipe 50, and a fall prevention mechanism that prevents the material carrier 40 from falling. The fall prevention mechanism comprises: an engagement portion that engages a lifting member of a lifting device; a hooked plate having a locking portion pressed against the circumference of the first guide pipe 50 when the lifting member is released from lifting; a coil spring that tilts the hooked plate and presses the locking portion against the circumference of the first guide pipe 50; and a guide frame that is attached to the top plate to guide the tilting of the hooked plate.SELECTED DRAWING: Figure 1
【課題】落下防止機構を荷揚げ装置に取り付けるに際し、接触部材が垂直棒状部材に対して滑らないようにして、確実に資材運搬体の落下を防止できるようにする。【解決手段】断面が円形の第１案内パイプ５０に沿って昇降する調整箱１０と、調整箱１０に連結された資材運搬体４０とを備え、調整箱１０は、上面板を有する箱枠体と、第１案内パイプ５０の周面上を滑って昇降する昇降体２０と、資材運搬体４０の落下を防止する落下防止機構とを備え、落下防止機構は、吊り上げ装置の吊り上げ部材に係合する係合部と、吊り上げ部材の吊り上げが解除されたときに第１案内パイプ５０の周面に押し付けられるロック部を有するかぎ状板と、かぎ状板を傾斜させて第１案内パイプ５０の周面にロック部を押し付けるコイルバネと、上面板に取り付けられてかぎ状板が傾斜するのを案内する案内枠を備える。【選択図】図１
