RU2517843C1 - Hand hammering tool for ice crushing "gololyod-1" - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: hand tool consists of a guiding rod and an operating member with pointed tip. The guiding rod is fitted by a hammering element and set in the longitudinal axially symmetric hole of the hammering element. The hammering element is provided with the possibility of increasing its weight, falling along the rod axis and hammering impact on the operating member.

EFFECT: invention allows for the adjustment of impact energy due to the alteration of the hammering element weight, its initial acceleration and height of fall.

Description

FIELD OF THE INVENTION

The invention relates to hand tools of percussion and can be used for chipping ice on the icy surfaces of the paths of movement of people and vehicles or for other purposes.

State of the art

Known hand tool percussion for the destruction of ice - ice pick, consisting of a wooden rod and mounted on its end steel working body, for example, a pointed scapula. It is used for cutting holes in the ice of water bodies by impact on ice. See, for example, on the website http://www.rybolov.ru/lib/biblio_rybolov/14.html V. Kirillov’s book: How to choose an ice pick? Section tips.

Known manual tool percussion for the destruction of ice - scrap ice ax, including a sleeping rod with a special ax-shaped sharpening of one or two ends (used by wipers to chip the ice when striking the ice with a crowbar). See, for example, the book of E. Muravyov. Plumbing. - M .: "Enlightenment", 1984, p.40, Fig. 21.

Known devices for manual destruction of ice require great physical effort. Scrap, for example, weighing up to 7 kg is required each time to be raised to a height of 0.3-0.5 m to perform useful work on cleaving ice formations.

Disclosure of invention

A manual tool for breaking ice includes a guide rod, a shock element and a working body with a pointed part, the guide rod being placed in a longitudinal axisymmetric hole of the shock element, and the shock element is made with the possibility of increasing its mass and the possibility of falling along the axis of the rod under impact working body.

When lifting the shock element, then releasing it, the shock element falls, moving along the guide rod, it strikes the working body, the piercing part of which destroys the ice formation.

Brief Description of the Drawings

Figure 1 presents a General view of a hand tool percussion for breaking ice.

Figure 2 shows a structural diagram of a hand tool.

The implementation of the invention

A hand tool for breaking ice includes a tubular grip 1 connected rigidly with a percussion element 2 made with a hole coaxial with the longitudinal axis of the tubular grip, inside of which there is a guide rod 3 of circular cross section, rigidly connected to the working body 4 with the pointed part 5 moreover, the shock element is made to fall along the guide rod and impact on the working body, and the contacting surface of the tubular grip 1 with the shock element 2 and pressure razvivayuschie rod 3 have antifriction coatings, for example, of plastic.

The mass of the shock element 2 can be increased by an additional load 6, bolted 7 to the shock element 2.

Hand tool percussion for breaking ice works as follows. In the vertical position of the tool with the help of a tubular gripper 1, the impact element 2 is lifted by hand. Releasing the impact element at zero initial speed or imparting initial acceleration, the impact element is impacted on the working body, destroying the icy coating with its piercing part.

The impact energy can be adjusted by changing the mass of the impact element, its initial acceleration and the height of the fall.

Claims (1)

A hand tool of impact for breaking ice, comprising a rod and a working body with a pointed part, characterized in that the guide rod is provided with a shock element and is placed in a longitudinal axisymmetric hole of the shock element, and the shock element is made to increase its mass, with the possibility of falling along the axis rod and impact on the working body.
