Balance adjustment mechanism for power cable pay-off rack

Abstract

The invention discloses a balance adjustment mechanism for a power cable pay-off rack. A cross bar is placed at the tops of supporting devices. A bothway hydraulic cylinder is installed in an inner cavity of the cross bar, and the two ends of the bothway hydraulic cylinder are both provided with piston rods. Crash pads are bonded to the outer surfaces of the piston rods. T-shaped base plates are arranged at the bottoms of the supporting devices. Balance adjustment devices are installed at the bottoms of the T-shaped base plates and are further composed of upper shells, attachment bolts, rubberbuffer blocks, positioning plates, springs, lower shells and rubber damping plates. According to the balance adjustment mechanism for the power cable pay-off rack, the piston rods are slowly jacked up at the constant speed in opposite directions, clamping force is generated from the inner circle of a cable reel, the effect that the take-up and pay-off processes are more stable is guaranteed, themultiple sets of the balance adjustment devices are kept stable together, the effect that the whole device can be stressed more evenly is ensured, working is more stable, the phenomenon of local uneven stressing is avoided, and the installation stability of the inner structure is reinforced.

Description

technical field [0001] The invention relates to the technical field of electric power transportation, in particular to a balance adjustment mechanism of a power cable pay-off frame. Background technique [0002] Power cables are generally located at high altitudes, or underground, or even in pipelines. The laying of power cables in different regions also has certain work difficulties. Some pay-off racks or pay-off vehicles cannot automatically fix the cable reel, and will damage the cable reel in the project of rewinding and unwinding. The cable reel will have cracks after accumulated wear and tear, and may also cause safety hazards. Moreover, the cable During the process of unwinding or taking up the coil, it needs to bear part of the working pressure. This pressure will cause a part of the impact on the pay-off frame. If this type of pressure cannot be effectively offset, it will cause damage to the pay-off frame and affect the cable. Normal operation of pay-off. Conten...
