Electric power construction tool

Abstract

The invention discloses an electric power construction tool which structurally comprises a head, a body, a working head, a handle, a bracing plate and a die punching structure. An electric pump is mounted in the head, the electric pump is connected to an oil conveying hose arranged in the body, the working head is mechanically connected to the body, the die punching structure is fixed by the bracing plate and is opposite to the working head, the die punching structure comprises a bolt hole, a die punching port, an upper die, a lower die, a die seat, a hole detection part and a supporting flatseat, and the upper die and the lower die are connected by a bolt. As a locking bolt is loosened, when a pressure is smaller than an elastic force of a shock absorbing spring, vertical supporting corners matched on two sides of the shock absorbing spring will push a vertical expansion part upward, and a triangular cone penetrates into a moving port gradually till leaning against the upper edge ofthe upper die. Along with penetration of the triangular cone, the diameter of the moving port is increased continuously, a left moving body protrudes, and the inner wall of a die punching port is notsmooth, so that the condition that the locking bolt is loosened can be known intuitively. The degree of tightness needs to be adjusted to guarantee the punching quality.

Description

technical field [0001] The invention relates to the field of electric power construction, in particular, it is an electric power construction tool. Background technique [0002] At present, the high-voltage primary equipment in the domestic power system is connected by steel-cored aluminum stranded wire or aluminum row and copper row. For the punching of aluminum row and copper row, separate hydraulic punching is used. The split hydraulic punching machine is composed of a manual pump or an electric pump and a hydraulic punching working head. The hydraulic punching machine is punching. Vibration cannot be avoided at all times, and long-term vibration will cause the screws to loosen. This will not only lead to no guarantee of the quality of the hydraulic punching machine, but also cause serious threats to human life, so you should check the screws before and after use.

[0002] At present, the high-voltage primary equipment in the domestic power system is connected by steel-cored aluminum stranded wire or aluminum row and copper row. For the punching of aluminum row and copper row, separate hydraulic punching is used. The split hydraulic punching machine is composed of a manual pump or an electric pump and a hydraulic punching working head. The hydraulic punching machine is punching. Vibration cannot be avoided at all times, and long-term vibration will cause the screws to loosen. This will not only lead to no guarantee of the quality of the hydraulic punching machine, but also cause serious threats to human life, so you should check the screws before and after use. It is not tightened. Since there are many screws used to fix the mold, it is necessary to move them one by one to see if they are loose during the inspection. Inspection mistakes often occur through manual inspection with the naked eye.
