Abstract
The portable mechanically assembled ground fixation stake device is applied to the engineering of treating land earthwork, water-based desilting, excavating materials, moving, land, underwater heavy objects, civil engineering, harbor, river, lake construction and the like, and is characterized in that the whole device is fixed only by the action of the working tensile force itself. The whole device has six stake columns 2a, 2b, 4a,4b, 9, 1) arranged on the ground, wherein four constituent brackets (2a, 2b, 4a, 4b) are supported on the ground. The top ends of the four supports are mounted on the shaft (6), and a cuboid rigid block (15) is mounted in the middle of the shaft (6). When the system is subjected to pulling force, the cuboid rigid block (15) rotates around the central shaft (6), and due to the opposite movement direction of the two end points of the cuboid rigid block (6), the tension conversion direction of the system forms an inclined downward pressure, so that the protective stake (9) is subjected to pressure at the same time from the pressure rod (7), and due to the fact that the tensile force and the pressure are synchronized, the greater the tension force is also increased, so that the whole device achieves the effect of fixing the stake. The device is light in weight and convenient to carry, and can be mounted and disassembled anywhere.
