The present invention relates to a holdable hydraulic compressor and a sleeve compression construction method using same. More specifically, the present invention provides a holdable hydraulic compressor and a sleeve compression construction method using same, which enable a single person to perform an operation alone by holding (fixing) a sleeve in a state where the sleeve is positioned at a compression position before applying pressure to compress the sleeve in a state where the sleeve is positioned at the compression position.

Abstract

The present invention relates to a cable connection device and an uninterruptible power distribution method and, more specifically, to a cable clamp connection device having an insulating lifting function and an indirect live wire uninterruptible power distribution method using the device, the uninterruptible power distribution method: allowing a construction cable clamp to be towed and lifted by a mechanical operation caused by a small force of a live wire electrician, unlike a conventional uninterruptible power distribution method in which a heavy construction cable clamp has been connected and removed until now by relying on the physical strength of a live wire electrician; and, differently from a process, in the conventional method, in which a temporary cable holder is separately provided so as to allow a construction cable to be mounted and then to be connected again to an extra high-voltage electric wire, allowing a cable clamp to be mounted, with an insulating towing belt, in the cable clamp connection device having an insulating lifting function, without using a temporary cable holder and enables the construction cable clamp to be immediately and directly connected to an extra high-voltage power line in the mounting state in a required process, thereby simplifying a work process so as to reduce work time, enabling a more complete electrical connection of the construction cable clamp through a simple mechanical operation rather than relying on the physical strength of the live wire electrician, and remarkably reducing the workload of a worker, and the like, such that onsite utilization, economical feasibility, and safety can be increased.

Abstract

The present invention relates to a manually-operated and extra-high voltage-insulated multifunctional safety hydraulic pliers stick for live-line work, which is designed to perform indirect live-line work on a distribution line, and, more specifically, to a manually-operated and extra-high voltage-insulated multifunctional safety hydraulic pliers stick for live-line work and a smart indirect live-line work method using the pliers stick, wherein, when equipment (pole fittings) and like installed on or removed from a pole in order to perform overhead line work or wire fixing are constructed by an indirect live-line work method during distribution equipment construction in an extra-high voltage live-line state, the pliers stick enables a worker to perform the construction with a strong gripping force, spreading force, or the like even from long distance while ensuring a safety distance from the live line, thereby removing dangers due to instability during the work, and enables the worker to perform various operations, thereby increasing the efficiency of use thereof.

Abstract

The present invention relates to an excavating screw for excavating locations where foundation piles or electric poles and earth wires are to be constructed when constructing foundation piles or the mechanical construction of electrical poles and earth wires. More specifically, the use of power is allowed through a rechargeable battery, such that the rechargeable battery is charged with power prior to the use of the screw and the power in the rechargeable battery is supplied to a camera during operation, whereby it is possible to carry out stable operation and to supply the power to the camera without need for separate unnecessary power supply cables. Soil or foreign material is frequently removed from the camera and the surroundings thereof through an air supply pipe, such that a stable field of view of the camera is secured at all times during operation, whereby operating time is shortened and working efficiency is significantly improved. Since the operation of the camera is enabled through wireless communication, unnecessary cables are not required, and thus operation performance is significantly improved.
