[0001] The present application relates to the technical field of garbage hoist of garbage power plant, and particularly relates to an oil cylinder pin shaft, an oil cylinder and a garbage hoist of garbage power plant. BACKGROUND
[0002] At present, the oil cylinder pin shaft structure used by the oil cylinder of the garbage hoist of garbage power plant is simple, only one bolt is twisted into the garbage hoist pin shaft to press the clamping block, thereby playing a fixing role.
[0003] Since the garbage hoist grab bucket is used in a harsh environment and needs to repeatedly grab garbage in the garbage pool, the weight of the garbage grabbed each time is 6-10T, and the garbage hoist is almost in operation all day long, the load is large. In addition, the leachate in the garbage is a corrosive liquid, and after long-term use, the pressing bolt will rust. Under the above circumstances, the pressing bolt of the pin shaft often breaks due to corrosion, strength reduction and other reasons. After the pressing bolt breaks, the oil cylinder pin shaft will slide out of the pin shaft hole in the use process because it is not fixed, which causes the separation of the oil cylinder of the garbage hoist and the claw piece of the garbage hoist grab bucket, and the grab bucket cannot be used.
[0004] In addition, when the oil cylinder pin shaft is disassembled, the bolt often cannot be normally disassembled due to rust, or the pressing bolt breaks in the pin shaft, which causes the pin shaft to be scrapped and cannot be used. Due to the above circumstances, the failure rate of the garbage hoist grab bucket is increased, the equipment cost is also increased, and personnel often need to repair the garbage hoist grab bucket, which increases unnecessary personnel investment.
