The invention discloses auxiliary cable installation equipment for a power transmission network, relates to the field of engineering machinery, and includes a hoisting device, an adjusting chassis, a branching device, and a caliper device. The motor on the hoisting device drives the small pulley, the belt and the big pulley to drive, and drives the hoisting wheel to rotate to perform the cable take-up and release work. If the circuit fails, it can also be realized by manually turning the handwheel. When the cable is too tight, the oil cylinders on the two symmetrically installed bottom frames drive the two bottom frames to adjust their relative positions around the crank, and the organ damping is used to ensure the stability of the structure. The determination of the left and right positions is realized through the positioning sensor on the branching device. The signal receiver is used to receive the signal. The cable can be divided into four ways and separated from different hooks to avoid entanglement. The cable is locked and released by the caliper on the caliper device, and the oil-pneumatic spring is mainly used to reduce the vibration caused to the equipment when the cable is tight and rebounds.

The invention relates to a carpet loom bobbin creel capable of making yarns inside the carpet loom bobbin creel pass through a yarn guide tube to a yarn guide plate and ensure that the yarns are not twisted and knotted. The carpet loom bobbin creel comprises a carpet loom bobbin creel; yarns are suspended on two sides of each group of bobbin creels in the carpet loom bobbin creel; and the suspended yarns pass through the yarn guide tube to the yarn guide plate respectively. The carpet loom bobbin creel has the advantages of: 1, fundamentally solving the problem that a lot of yarns on the bobbin creel are influenced by respective tension rate in the process of weaving the carpet so as to cause the phenomenon that the yarns are twisted and knotted and cannot be weaved; 2, ensuring the smooth operation of the yarns in the guide tube due to horizontal arrangement and feed between the yarn guide tube and yarn inlet and outlet or due to a design of horizontal arrangement and arc-shaped feed; and 3, novel, unique, simple and practical structure, and unexpected technical effects and economic benefit.
