Vibrating punching machine with returned oil cooling structure

Abstract

The invention discloses a vibrating punching machine with a returned oil cooling structure. The vibrating punching machine comprises a vibrating punching barrel body, a vibrating punching main shaft,a hydraulic motor and a multi-port receiving disc, wherein the inner cavity of the vibrating punching barrel body is divided into a first cavity and a second cavity by a bearing base; an oil inlet andan oil outlet of the hydraulic motor separately communicate with an oil tank through a system oil inlet connecting tube and a system oil return connecting tube; the system oil return connecting tubecomprises a system oil return part, a blocking part and a motor oil return part; the blocking part is positioned between the system oil return part and the motor oil return part; a motor oil return runner which communicates with the motor oil return part, and a system oil return runner which communicates with the system oil return part are arranged on the side wall of the vibrating punching barrelbody; an outlet of the motor oil return runner directly communicates with the second cavity; a through hole is formed in the bearing base; the through hole is used for enabling the first cavity to communicate with the second cavity; and an inlet of the system oil return runner directly communicates with the first cavity. A bearing group of the vibrating punching machine is long in service life and is low in replacing frequency; and production efficiency can be improved, and a safety coefficient can be increased while the vibrating punching machine is used to construct.

Description

technical field [0001] The invention relates to a device for constructing densified soft ground by a vibration method, in particular to a vibrator with an oil return cooling structure. Background technique [0002] The vibrating method, also known as the vibrating water flushing method, refers to a foundation reinforcement method developed on the principle that the sandy soil foundation can be compacted by adding water and vibrating. The vibro-shock method is a foundation reinforcement treatment method to improve the bad foundation to meet the foundation requirements of buildings (structures). [0003] The vibrator is the main construction equipment in the vibro-construction. Existing vibrator, such as a vibrator disclosed in CN 201730088 U, includes a polarization axis, a vibrator head, a motor, a main bearing, and a connecting flange. The surrounding wall of the punch shell is connected with an anti-twist guard plate, the front end of the vibrator shell is provided with ...

AI Technical Summary

Problems solved by technology

[0004] First, the heavy load resistance of the bearing is gradually weakened, and the fatigue life of the bearing is greatly reduced;

[0005] Second, bearings are often damaged and replaced frequently, which wastes unnecessary replacement time and greatly affects production efficiency;

[0006] Third, when shutting down for maintenance, unscrew the oil drain plug, high temperature and high pressure lubricating fluid will rush out of the cylinder, which may cause burns to maintenance personnel
