Description

Be applied to bearing roller device that drops of belt feeder Technical Field The utility model belongs to the technical field of belt equipment protection, and particularly relates to an anti-carrier roller falling device applied to a belt conveyor. Background The belt conveyor is widely applied to loading equipment and is a material transmission device for the loading equipment. The belt conveyor is rotated around a carrier roller frame through a carrier roller, so that sliding friction is converted into rolling friction, and the belt conveyor has supporting and driving functions. In practical application, because the carrier roller runs for a long time, the carrier roller can wear at the supporting part of the carrier roller frame, so that the carrier roller falls off, and the carrier roller falls off to cause physical damage to the lower return belt. In reality, the belt damage can cause great economic loss due to high manufacturing cost of the belt. Disclosure of utility model The utility model aims to provide an anti-carrier roller falling device applied to a belt conveyor, which comprises a carrier roller shaft and carrier rollers arranged on the carrier roller shaft, and further comprises two symmetrically arranged carrier roller frames, wherein each carrier roller frame is provided with a rotating groove in the direction far away from the carrier rollers, the tail end of each rotating groove is provided with a mounting hole in the direction far away from the carrier rollers, the carrier roller shaft penetrates through the rotating groove to be inserted into the mounting hole, a rotating block is fixedly connected to the outer side of the part, positioned in the rotating groove, of the carrier roller shaft, the rotating block is rotationally connected with the rotating groove, an annular stop block is connected in a sliding sealing manner in the rotating groove, one end face of the stop block is contacted with the end face of the rotating block, the other end face of the stop block is flush with the surface of the carrier roller frame, and a locking component is arranged between the stop block and the carrier roller frames. As a preferable scheme, the locking assembly comprises a fixed block fixed on the carrier roller frame, a pin hole is formed in the fixed block, and a bolt is inserted in the pin hole. As a preferable scheme, the outer surface of the stop block is fixedly connected with a hand holding block, and a through hole through which the bolt can pass is formed in the hand holding block. As a preferable scheme, a receiving plate is arranged below the carrier roller, and two ends of the receiving plate are respectively and fixedly connected with the carrier roller frame.
