The invention discloses a universal adjusting and fastening device for a chain type cable supporting mechanism, which comprises connecting pipes and fastening pieces, wherein one end of a vertical connecting pipe is connected with a vertical cable supporting mechanism; the other end of the vertical connecting pipe is connected with one end of a horizontal connecting pipe through a first fasteningpiece; the other end of the horizontal connecting pipe is connected between two ends of a second vertical connecting pipe through a third fastening piece; one end of the second vertical connecting pipe is connected with a horizontal cable supporting mechanism; the other end of the second vertical connecting pipe is connected with a second horizontal connecting pipe of a portal frame through a second fastening piece; two adjacent connecting pipes are vertical; and the second horizontal connecting pipe is vertical to other connecting pipes. The device of the invention is used for a chain type cable way, has the functions of connecting, fastening and adjusting between each cable supporting mechanism and the portal frame, can conveniently adjust the spatial positions of the vertical cable supporting mechanism and the horizontal cable supporting mechanism, can be well suitable for cables to smoothly pass through the cable supporting mechanisms, reduces the passing resistance and is convenient for installing and positioning the cable supporting mechanisms. The fastening pieces can be disassembled, thus when the cable supporting mechanisms have faults, the cable supporting mechanisms canbe repaired and maintained conveniently, thereby having important significance for reducing the use cost of the chain type cable way.
