Falling control device

The invention discloses a falling control device, and belongs to the technical field of petrochemical engineering. According to the device, the sliding block is driven by the sliding rod to slide in the second channel of the body, when the sliding block slides to the intersection of the first channel and the second channel of the body, the first channel can be blocked, and when the device is connected between the blowout prevention pipe and a target well, even if a target object in the blowout prevention pipe connected to the upper portion of the device falls off, the device cannot be blocked. When the target object falls into the first channel, the target object falls onto the sliding block at most due to blocking of the sliding block and does not continue to fall into a target well connected with the lower portion of the device, and therefore the accident of the falling object in the well can be avoided. 本申请公开了一种下落控制装置，属于石油化工技术领域。该装置通过滑杆带动滑块在本体的第二通道内滑动，当滑块滑动到本体的第一通道与该第二通道的相交处时，能够封堵该第一通道，当该装置连接在防喷管与目标井之间时，即使
