Abstract

The invention relates to a circulating lubrication structure of a vibration hammer. The circulating lubrication structure comprises a shell, a plurality of first rotating shafts and a rotating shaft driving component, a first bearing and a first bearing block are arranged among two ends of each rotating shaft and the shell, a lubrication oil placing cavity is formed in the shell, a circulating lubrication component is arranged on the shell, lubrication oil is guided and drained to bearings from the lubrication oil placing cavity by the circulating lubrication component, the circulating lubrication component comprises an oil pump, an oil pump channel, a flow distribution component and a first lubrication channel, the flow distribution component comprises a flow distribution plate and a flow distribution channel, the flow distribution plate is arranged above the shell, the flow distribution channel is formed in the flow distribution plate, the flow distribution channel is provided with at least one oil inlet and a plurality of first oil outlets, the oil pump channel is formed among the lubrication oil placing cavity and the oil inlets, each first oil outlet and the corresponding first bearing block are corresponding at the relatively vertical position, and the first lubrication channel is vertically formed among the first oil outlets and inner cavities of the first bearing blocks. By the aid of the scheme, the circulating lubrication structure of the vibration hammer is smoother in lubrication.

Description

technical field [0001] The invention relates to a vibratory hammer, in particular to a circulating lubrication structure of the vibratory hammer. Background technique [0002] Vibratory hammer is a pile sinking and pulling construction machine widely used in various foundation construction projects such as urban construction, bridges, and ports. The vibratory hammer uses the vibratory piling method to drive the pile. The principle of the vibratory piling method is: the periodic exciting force generated by the vibratory hammer causes the pile to vibrate, softening the soil around the pile, so that the friction force of the soil on the pile is greatly reduced, and the pile It can sink into the soil under the action of vibration force and its own gravity. [0003] The traditional vibratory hammer includes a vibration damping device, a vibration device and a clamping device. The vibration damping device includes a vibration damping shell and a vibration damping assembly. One e...

Problems solved by technology

Often, a lubricating oil storage chamber is provided in the vibration damping shell and the bearing is lubricated by splash lubrication, and the splash lubrication relies on the high-speed rotation of the eccentric block on the rotating shaft in the vibrating shell to throw the lubricating oil to the inner wall of the vibrating shell , but due to the special structure of the vibrating shell, it is easy to cause dry friction of the bearing and damage it, which increases the probability of early failure of the bearing and greatly reduces the service life of the bearing

[0004] The above problems are not solved, and the patent document with the application number 201010137305.9 discloses a vibration chamber bearing cooling and lubrication system for a vibratory hammer. The oil in the lubricating oil chamber is first extracted to the oil separation block through the oil suction pipe and the oil pump, and then the oil is separated by the oil separation block. The lubricating oil is delivered to the inner cavity of each bearing through the lubricating oil pipe, so as to realize the lubrication one by one and ensure the lubricating effect. Once the rotating shaft with eccentric block is added to increase the excitation force of the vibrating hammer, the bearings and lubricating oil pipes will inevitably increase, and the arrangement of the oil pipes gathered in one place is relatively messy, easy to knot, bend or squeeze each other. For those who often work at heights If the vibratory hammer is not found in time, it will cause poor lubrication effect. During the maintenance or daily inspection of the vibratory hammer, messy oil pipes will also greatly increase the time required for work.
