Self-lubricating portal crane

Abstract

The invention discloses a self-lubricating portal crane. The self-lubricating portal crane comprises a rotary drum, wherein rotary drum fixing blocks are rotatably connected to the left end and the right end of the rotary drum, a lifting hook line is wound around the outer circle surface of the rotary drum, lifting hook fixing blocks are arranged at the lower side of the rotary drum, and lifting hooks are fixedly connected to the lower ends of the lifting hook fixing blocks; and the upper ends of the lifting hook fixing blocks are fixedly connected with a lifting hook line, a switching power mechanism is arranged in the rotary drum fixing block at the left side, and a rotary shaft is rotatably connected to the end, away from the rotary drum, of the rotary drum fixing block. According to the invention, dust on the surface of the machine can be removed in a running process, and the running state of the machine is prevented from being affected by particulate matter such as dust; and meanwhile, evaporation of water on the surface of the machine can be accelerated after raining to prevent rainwater from staying for a long time to corrode the surface of the machine to affect the working state, lubricating liquid can be automatically supplemented in the running process, and the situation that the service life is affected by abrasion of the machine due to too little lubricating liquid is prevented.

Description

technical field [0001] The invention relates to the field of cranes, in particular to an automatic lubricating gantry crane. Background technique [0002] During the use of the crane, it is necessary to replenish lubricating oil in time. Once the lubricating oil is not replenished in time, it will cause wear between parts and affect the service life of the crane. At the same time, because many gantry cranes are used outdoors, they are easily affected by rain. Influence, once the rain falls on the surface of the machine for a long time, it will cause the rust of the machine and reduce the service life of the machine. At the same time, the continuous accumulation of dust will affect the operation of the machine and affect the service life of the machine. An automatic lubricating gantry crane described in the present invention can solve the above problems. Contents of the invention [0003] In order to solve the above problems, a kind of automatic lubricating gantry crane is...
