Title:
DOUBLE-HEAD TROWELLING MACHINE SELF-ADAPTIVE BALANCING MECHANISM AND ADJUSTING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/233271
Kind Code:
A1
Abstract:
A double-head trowelling machine self-adaptive balancing mechanism and an adjusting method thereof. A water tank (1) and an engine (9) are respectively mounted on flexible shock absorbers (10) mounted on two trowelling power shafts (11) fixedly mounted at two ends of a dovetail-type underframe (13); one end of an adjusting lead screw (4) close to the engine (9) is coupled to a stepping motor (8) by means of a coupling (7); the adjusting lead screw (4) is provided with a counterweight block (6) and two ends of the adjusting lead screw are provided with lead screw supporting bases (3); and the counterweight block (6) is adjusted by a sensor and controller (5) and the stepping motor (8) to enable the mechanism to adaptively balance in real time, and is supported by a guide rail (2). The adjusting method comprises: as the amount of water decreases during working, the sensor and controller (5) sends a detected angle change signal of the guide rail (2) that is inclined to the controller for processing and issues information to control the stepping motor (8), and adjusts the position of the counterweight block (6) by driving a ball lead screw for adaptive balance adjustment. The trowelling machine needs only one single motor to drive, and may enable the pressure of two trowelling heads to the ground to be in a dynamic balance.
