一种防止箕斗仓门自行打开的双重保护装置
摘要：
本实用新型提供一种防止箕斗仓门自行打开的双重保护装置。所述防止箕斗仓门自行打开的双重保护装置包括：框架；立方悬挂装置，立方悬挂装置的底部设置于框架的顶部；张力自动平衡悬挂装置，张力自动平衡悬挂装置的底部设置于立方悬挂装置的顶部。本实用新型提供的防止箕斗仓门自行打开的双重保护装置，能够防止斗箱和活动斗底自行打开或者关闭不严的情况，避免了如有少量废石或石粉附着在仓门口，导致底门被卡关闭不严的情况时有发生，箕斗在井下计量斗装满废石的时候，受废石重量影响，箕斗仓门便被挤压打开，废石从箕斗内掉落至井底，更严重时甚至出现箕斗错位、使箕斗脱离罐道，撞击井架及罐道木，损坏井筒内设施的情况发生。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model provides a dual-protection device for preventing a skip bucket bin gate from being automatically opened. The dual protection device for preventing the skip bucket bin gate from beingautomatically opened comprises a frame; the bottom of the cubic suspension device is arranged at the top of the frame; and the bottom of the automatic tension balance suspension device is arranged atthe top of the cubic suspension device. The utility model provides a dual-protection device for preventing a skip bucket bin gate from being automatically opened. the situation that the bucket box and the movable bucket bottom are automatically opened or not tightly closed can be prevented; a small amount of waste stone or stone powder is prevented from being attached to the bin gate; when an underground measuring hopper is filled with barren rocks, a skip bin door is squeezed to be opened due to the influence of the weight of the barren rocks, the barren rocks fall to the bottom of a well from the skip, and even the skip is misplaced, so that the skip is separated from a shaft guide, impacts a derrick and shaft guide wood and damages facilities in the shaft.
