Forward and backward rotation power box for deep-layer cement mixing pile

Abstract

The invention discloses a forward and backward rotation power box for a deep-layer cement mixing pile. A hollow pipeline is arranged at the middle portion of a drive gear, the middle portion of a forward rotation planetary gear box and the middle portion of a backward rotation planetary gear box. A rotating shaft is located in the hollow pipeline. The end, away from a support, of the hollow pipeline is connected with a grout sprayer. A clutch is fixed to the position, with the height the same as a power device, on the hollow pipeline. The forward rotation planetary gear box and the backward rotation planetary gear box are installed on the hollow pipeline. The drive gear is fixed to the rotating shaft. A forward rotation sun gear is located in the forward rotation planetary gear box. Forward rotation planetary gears surround the outer side of the forward rotation sun gear and are connected with the forward rotation sun gear in an engaged manner. A backward rotation sun gear is located in the backward rotation planetary gear box, and backward rotation planetary gears surround the outer side of the backward rotation sun gear and are connected with the backward rotation sun gear in an engaged manner. The forward and backward rotation power box for the deep-layer cement mixing pile can rotate forward and backward and is simple in structure and long in service life.

Description

technical field [0001] The invention relates to the technical field of piling equipment, in particular to a forward and reverse power box of a deep cement mixing pile. Background technique [0002] The cement mixing pile uses cement as the main agent of the curing agent, which is an effective form of soft ground treatment. The cement is sprayed into the soil by a mixing pile machine and fully stirred, so that a series of physical and chemical reactions between the cement and the soil occur, making the soft ground The soil is hardened into a high-strength foundation with integrity and stability, but the deep cement mixing pile currently on the market has a complex structure, is inconvenient to use, and the mixing is not sufficient. Therefore, the present invention proposes a deep cement mixing pile. power box. Contents of the invention [0003] The object of the present invention is to provide a forward and reverse power box of a deep cement mixing pile to solve the proble...
