Abstract: The invention provides a thermosyphon foundation, a method of calculating cold conductivity enhancement coefficient and a method of cold conductivity enhancement thereof. The cold conductivity enhancement coefficient is obtained by using parameters including freezing index, latent heat of soil thawing, thermal resistance of pre-buried hole without injection of a cold conductivity enhancement medium, thermal resistance of cold conductivity enhancement mass or the like, and by using formulas for calculating the cooling radius of the thermosyphon without injection of a cold conductivity enhancement medium and the cooling radius of the thermosyphon after injection of a cold conductivity enhancement medium. The invention determines whether to proceed with subsequent construction by using the cold conductivity enhancement coefficient, and achieves cold conductivity enhancement for the thermosyphon foundation by using the method of cold conductivity enhancement.

The power supply (120) is installed on one side of the chassis (111); and the heat conduction layer (130) is arranged between the power supply (120) and the chassis (111) to conduct heat generated by the power supply (120) to the chassis (111).

Abstract: A method for a robot to automatically find a bending position, including the following steps: step 1, establishing a gripper tool coordinate system (TX, TY, TZ); step 2, determining a user coordinate system (XA, YA, ZA; XB, YB, ZB) of rear blocking fingers (11, 21); step 3, a robot gripper moving horizontally, and detecting the state of sensors (12, 22); step 4, the robot gripper executing a rotational movement, detecting the state of the sensors (12, 22), and thereby obtaining a standard bending position. The robot automatically finds the bending position, the teaching difficulty is reduced, and the bending quality is increased. In the elevator industry, elevator door plate bending sizes are the same, but forming sizes are different. In the present invention, only one product process needs to be taught in order to satisfy elevator door plate processing with different specifications, thereby reducing maintenance costs and increasing production efficiency.
