RU92846U1 - EASY-REMOVABLE RUBBER-METAL TRACK OF A FORESTRY TRANSPORT MACHINE - Google Patents

Abstract

 Easily removable rubber-metal caterpillar of a forest transport machine, made in the form of a tape and equipped with a connecting link in the form of a plate located at one end of the tape, characterized in that across the tape there are pairs of guide ridges made U-shaped, the plate is made curved with a radius of curvature greater than the diameter of the wheel forest transport machine and is equipped with a rotary eccentric clamp, and at the second end of the belt hooks are formed, forming end grooves.

Description

The utility model relates to the field of snow and swamp technique and can be used in high-cross-country forestry vehicles with pneumatic tires.

A device for connecting the ends of an elastic caterpillar, which is a loop of tape applied to the main track fabric and secured by plates with holes for the fingers [1].

A disadvantage of the known device [1] is that there is no device for closing the track contour in the field.

For the effective use of forestry vehicles in various soil conditions, it is necessary to quickly mount a rubber-metal track on a pneumatic-wheel undercarriage

The technical task of the utility model is to create an elastic track with a compact device for closing the track circumference of the rubber-metal track in the field using pneumatic tires, for example, directly on the cutting area.

The technical problem is achieved due to the fact that the rubber-metal caterpillar, in the form of a tape, is equipped with a connecting link in the form of a plate located at one end of the tape, with pairs of guide ridges made U-shaped across the tape, the plate is made curved with a radius of curvature greater than the radius of the wheel forest transport machine and is equipped with a rotary eccentric clamp, and at the second end of the belt hooks are formed, forming end grooves.

Comparison of the claimed utility model with the prototype shows that it differs in the following features:

- moreover, across the tape are pairs of guide ridges;

- ridges are made U-shaped;

- the plate is made curved with a radius of curvature greater than the radius of the wheel of the forest transport machine;

- the plate is equipped with a rotary eccentric clamp;

- hooks are formed at the second end of the belt, forming end grooves.

Therefore, we can assume that the claimed utility model meets the criterion of "novelty."

The utility model can be performed on standard equipment using well-known technological processes, therefore it meets the criterion of "industrial applicability".

The proposed technical solution is illustrated by an example of its use and the accompanying drawings, where figure 1 shows a General view of the sent out rubber-metal tracks: 1 - track; 2 - a connecting link; 3 - rotary eccentric clamp; 4 - forest transport machine; 5 - caterpillar hooks; 6 - guides U-shaped ridges located along the length of the tracks in pairs. In figure 2 is a cross section of a caterpillar dressed on wheels; figure 3 - fixation due to the friction of the guide ridges of the connecting link on the pneumatic tire of the forest transport machine; in figure 4 - the formation of a closed caterpillar contour on a pneumatic wheeled trolley dissolution of a forest transport machine; figure 5 - approximation of the connecting link with a rotary eccentric clamp to the hooks of the tracks; figure 6 - connection of the ends of the tracks using a rotary eccentric clamp: 7 - eccentric clamp; 8 - end grooves; in figure 7 - capture by an eccentric clamp of the hook of the track when passing through the end groove; figure 8 - fixing the track eccentric clamp.

The device operates as follows: a forest transport machine 4 (the figures show the dissolution of a forest transport machine) drives onto a sent rubber-metal track 1 from the side to the opposite connecting link 2 (Fig. 1); the track has guiding U-shaped ridges 6 (Figs. 1, 2) located in pairs along the length of the track to prevent the track from falling off the wheels and allowing the wheels to move to the connecting link 2. When the wheels are pulled over the lateral ridges 6 of the connecting link 2, it fixing on the tire due to friction between the cheeks of the guides of the U-shaped ridges 6 and the sidewall of the pneumatic tire (figure 3), because the width between the cheeks of the guides of the U-shaped ridges 6 of the connecting link 2 is equal to the width of the profile of the pneumatic tire; when the dissolution is moved in the opposite direction, the caterpillar 1 is wrapped around the first dissolution wheel 4, because the plate of the connecting link 2 in linear dimensions exceeds the gap between the wheels of the dissolution of the connecting link 2 will engage with the second wheel (figure 4); further movement of the dissolution will allow to bring the connecting link 2 with a rotary eccentric clamp 7 to the hooks 5 on the track (figure 5); when turning the eccentric clamp 7 (Fig.6) it will engage with the hooks 5 of the track through the end grooves 8 (Fig.7), further rotation of the eccentric clamp 7 will lead to the connection of the track. In the closed state, the caterpillar is shown in Fig. 8.

The caterpillar is mounted on the wheels of dissolution only due to the movement of the forest transport machine without the use of any lifting mechanisms.

Removing the track from the pneumatic wheels is carried out in the reverse order.

Thus, the claimed utility model of an elastic caterpillar with a compact device for closing a caterpillar contour of a rubber-metal caterpillar allows in the field to mount a rubber-metal caterpillar on a pneumatic wheel undercarriage.
