Abstract

The invention relates to the mechanization of roofing work, in particular to devices for repairing the roof. The purpose of the invention is to increase productivity and prevent damage to the surface. The device for cleaving the soft roof covering contains a frame, a chassis and a cutting tool body made of two sections 5 and 6. The sections are interconnected on an inclined surface with the possibility of their fixed mutual displacement in the direction of this surface. The cutting edge 4 is inserted into the seam and the drive gear is engaged. When the cutting tool is inserted into the material, it performs a reciprocating motion. At the same time, the front section 5 under the action of the transverse component of the longitudinal impulse of the driving force makes a plane-parallel movement along the guides of the mortise lock 7. During the removal of the driving impulse within one cycle, the elastic element 8 returns the front section 5 to its original position. 3 il.

Description

fig 2

The invention relates to the mechanization of roofing work, in particular to devices for repairing the roof, and can be used to remove the roll carpet from the roof.

The purpose of the invention is to increase productivity and prevent damage to the surface.

FIG. 1 shows the proposed machine, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2

The device for cleaving soft roofing contains a frame 1, a chassis with a drive 2 and a cutting tool 3 in the form of a plow with a cutting edge 4. Cutting tool 3 consists of the front 5 and back b sections connected by a mortise lock 7, like a dovetail and elastic element 8.

The front section 5 is mounted with the possibility of plane-parallel movement relative to the rear section b fixed on frame 1. The slot lock 7 is inclined to the cutting edge 4, the angle of inclination being greater than the friction angle for the particular joint forming the lock (in this embodiment 8 °) and corresponds to the optimal ratio of longitudinal and transverse motivating vectors {for a roll coating of 4-5 layers 5/1).

The machine for cutting and removing from the surface of the web material works as follows,

On the roof covering a pre-special device is cut into seams so that the coating is broken into squares of 300x300 mm. The machine is then brought to the roof covering, its cutting edge 4 is inserted into the seam, the drive gear of the chassis 2 and the cutting tool body 3 is activated. When the cutting tool body 3 is inserted end-to-end, it makes a reciprocating motion between the roof covering and the base.

This front section 5 under the action of the transverse component of the longitudinal impulse of the driving force makes a plane-parallel movement along the guides of the mortise lock 7. During

the removal of the urging (initial) pulse within one cycle; the elastic element 8 returns the front section 5 to the initial position.

Thus, along with the reciprocating movement of the cutting tool body 3, there is a plane-parallel movement of its front section 5, which ensures optimal conditions for the separation of the roofing

coatings from the base. The strips of the roll covering are retracted away from the machine and then removed from the roof.
