Abstract

The invention relates to an adjustment device for a trowel plate of a floor troweling machine and a floor troweling machine. The adjustment device includes a three-degree-of-freedom parallel mechanism and a frame; A moving platform with two rotational degrees of freedom along the z-axis and a translational degree of freedom along the z-axis; an input shaft is connected to the frame in rotation, and a power input unit is installed at one end of the input shaft; After moving the platform, it is connected with the other end of the input shaft, and the wiper shaft is slidingly connected with the moving platform through a sliding bearing; a wiper adjustment sleeve is arranged on the outer cover of the wiper shaft at the lower part of the moving platform, and one end of the wiper adjustment sleeve It is fixedly connected with the moving platform, and the other end is connected with the smear of the smear plate through the smear tilt adjustment rod. The invention can simultaneously realize the real-time automatic adjustment of the two-direction swing of the wiper plate and the inclination angle of the wiper on the wiper plate, has the advantages of simple structure, decoupling of adjustment of each degree of freedom, easy control, etc., and has wide application prospects.

Description

technical field [0001] The invention relates to an adjusting device, in particular to an adjusting device for a floor troweling machine for building construction and a ground troweling machine containing the device, belonging to the technical field of building construction equipment. Background technique [0002] Ground troweling machine is an important equipment for building construction. According to the existing literature, ground troweling machine is divided into two types: linear troweling and rotary troweling according to the troweling movement. The linear troweling machine adopts a linear scraper, and the troweling machine moves in a straight line perpendicular to the direction of the scraper to complete the troweling movement. The rotary troweling machine adopts a rotating trowel, and the trowel moves along the ground in a straight line while the trowel rotates, so as to smooth the ground. According to the different forms of the wiper, the rotary trowel is divided i...
