Problems solved by technology

In the power grid, when the generally circular transmission cables freeze, no matter whether it is manual or mechanical operation to break the ice, the effect is not good due to the narrow striking surface, so the work progress is slow

Embodiment Construction

[0010] see Figure 2~4 , the hammer body is composed of a vertical section and an arc section, and the cross section of the hammer body is square, and the inner angle of the arc section is a semicircle angle, the diameter of the semicircle angle is larger than the diameter of the cable, and the vertical The top of the straight section is fixed with a plurality of cones, and the handle is fixed on the vertical section of the arc hammer.

[0011] The basic hammer shape adopts an arc shape, which is close to the circumference of the cable. In this way, the ordinary hammer can only strike at the tangent point and increase to the striking surface close to the semicircle. The ice on the cable will be greatly crushed and dropped. , which is why the progress is increased.

[0012] figure 1 , figure 2 A plurality of cones 3 are fixed on the top of the vertical section (i.e., the cube section). Vertical section of hammer body 2 (see figure 1 ) with 4 cones at the top.

Abstract

The invention relates to a special arc-shaped cable deicing hammer. A hammer body consists of a vertical section and an arc-shaped section. The cross sections of the hammer body are square. An included angle formed by the internal sides of the arc-shaped section is a half circumference angle. The diameter of the half circumference angle is larger than the diameter of a cable. A plurality of cones are fixed at the top of the vertical section. A handle is fixed at the vertical section of the arc-shaped section. Compared with the existing striking hammer, since the original cable tangent striking point is increased to a circumferential striking surface, the special arc-shaped cable deicing hammer has the characteristics of high deicing efficiency, unique structure, convenience in use and high practicability.

Description

technical field [0001] The present invention relates to appliances for deicing overhead power lines, in particular manual or mechanical cable deicing appliances. Background technique [0002] In order to concentrate the force, ordinary hammers and nail hammers use the end strike method. Although they can also be used horizontally, the force is also flat. In the power grid, when the generally circular transmission cables freeze, no matter whether it is manual or mechanical operation to break the ice, the effect is not good due to the narrow striking surface, so the work progress is slow. Contents of the invention [0003] The object of the present invention is to provide a special arc hammer for cable deicing which is convenient to use and has good deicing effect. [0004] The object of the present invention is achieved as follows: a special arc hammer for cable deicing, the hammer body is composed of a vertical section and an arc section, and the cross section of the hamm...
