Description

DEVICE FOR SURFACE CLEANING FROM ICE

The utility model relates to municipal engineering and is intended for cleaning roads and sidewalks from snow and ice formations.

A device for removing ice from pavements according to the invention of the USSR No. 1677154 (MKI5 E01P5 / 12, zL1.04.89, op. 15.09.91), containing a vertical drive shaft, the lower part of which is made in the form of a crank, and a disk with a hard mounted on it with destructive tools mounted on a 1-pivot with the possibility of free rotation about its axis.

The disadvantage of this device is the low productivity and quality of cleaning due to the small contact area of the working tool with the treated surface.

The closest in technical essence and the achieved result to the claimed object is a device for cleaning surfaces from ice, containing working bodies mounted on the frame, which is a platform mounted on a vertical shaft of an electromagnetic drive with the possibility of free rotation in a horizontal plane on which elastic plates are fixed - cleavers at an angle to the plane of rotation of the platform and placed in plan radially relative to the axis of rotation of the platform, (see invention of the USSR 1449623, KI4 E01N5 / 12 3.08.05.87g, op.07.01.89g) -.. Prsugotip.

The disadvantage of the prototype is the low productivity and quality of cleaning due to a slight shift of chipped ice with free rotation of the platform.

.

The task underlying the utility model is to create a highly efficient device that provides increased productivity and cleaning quality due to the increase in the area of simultaneous destruction and subsequent ice cutting.

The problem is solved in that the device for cleaning surfaces from ice, containing a working body mounted on a frame with a vertical shaft and radial elastic plates, has a working body made in the inlet of the rotor, the radial elastic plates of which are mounted on the shaft flange and horizontally oriented in the plane of rotation flange. The free ends of each radial plate are equipped with a working tool and a roller. The frame is made in the form of a shell joined by belts, on the inner cylindrical wall of which are installed in alternating order with the possibility of contacting with rollers horizontal thrust and inclined lifting platforms. For the self-installation of working tools on uneven surfaces and for cutting off chipped ice, the working tool is made in the form of a block of rigidly connected parallel plates with a positive cutting front angle mounted on the central axis with the possibility of rotation. To increase the cleaning efficiency, the device is equipped with a counter-mounted second rotor with a frame, the radial elastic plates of which are located between the radial elastic plates of the first rotor in the same plane, and the rotor frames are connected by means of ball joints for limited rotation relative to each other when processing uneven surfaces.

In Fig.1 shows a device, a General view in section, on fr1g.2 - the same, view in plan, in Fig.Z - view A in Fig. 1, scan, in Fig.4 - node 1 in Fig. 1, figure 5 is a section bB in figure 4, figure 6 is a section bb in figure 2.

A device for cleaning surfaces from ice contains rotors 1 and 2, which are a vertical shaft 3 with flanges 4, on which

fixed radial elastic plates 5, horizontally placed in the plane of rotation of the flange 4 and carrying working tools 6 and rollers 7 at the free ends. Radial ufugi plates 5 of the rotor 1 are placed between the radial ufugi plates 5 of the rotor 2 in one plane. The rotors 1 and 2 are mounted on their frames 8 and 9, consisting of an upper belt 10 and a lower belt 11, open on the side of the working tools nto 6, interconnected by a shell 12. On the inner cylindrical walls of the shell 12 are installed with the possibility of contact with rollers 7 in alternating order, horizontal thrust platforms 13 and inclined lifting platforms 14. The distances between the platforms 13 and 14 are determined by the free passage of the rollers 7 between them, and the angle of inclination of the lifting platforms 14 is determined by the elasticity of the plates 5. Direction of inclination Removable pads 14 frames 8 and 9 vsholneny opposite. The working tools 6 can be in the form of teeth, knives, etc. For self-installation of the working tool on uneven surfaces and providing a shearing-cutting action, the working tool 6 is made in the form of a block of two parallel plates 15, having a positive cutting front angle, fastened through spacer holes 16 with rivets 17 and mounted on the central axis 18. Each block of the working tool 6 with its central axis 18 is mounted for rotation on a bracket 19, mounted on an elastic plate 5. The length of the horizontal thrust pad 13 is equal to the distance between the plates 15 of the block of the working tool 6 to ensure ice cutting between the plates 15 using the weight of the device transmitted to the roller 7 through the thrust pad 13. To transmit torque and counter rotation of the rotors 1 and 2, their shafts 3 are connected by cylindrical gears 20 through spurious gears 21.

Frames 8 and 9 are connected by hinges 22, the axes of which are located at the level of gears 20 and 21, for a limited “folding of frames on uneven

surfaces. On the upper belt 10 of the frames 8 and 9, removable weights 23 are installed to control the weight of the device, and on the lower belt 11 - rubber shock absorbers 24, which prevent damage to the rollers in the presence of recesses on the surface being cleaned.

The device operates as follows.

The device is suspended on the vehicle and the shaft 3 of the rotor 1 is rotated in the direction of inclination of the lifting platforms 14 from the autonomous drive or power take-off shaft of the vehicle (not shown). Gears 20, 21 transmit counter-rotation to rotor 2. Then, the device is lowered onto the ice of the surface to be cleaned with working tools 6, the contact of which with the road surface is ensured by the elasticity of the radial plates 5 and through the rollers 7 by the thrust platforms 13. Rohs 7 run onto inclined lifting platforms 14, bending elastic plastics 5. When the rollers 7 exit the lifting platforms 14 of the plate 15 of the working tool blocks 6, they strike the ice. With the simultaneous rotation of the rotors, the roller 7 goes under the platform 13 and the plates 15 of the blocks of working tools 6 cut off the destroyed sections of ice from the surface being cleaned due to the elasticity of the plates 5 and the weight of the device transferred to the roller 7 through the thrust against the platform 13. At the same time, the vehicle and the blocks of working tools move 6, counter-rotating rotors, clean new areas, providing high-performance) high-quality cleaning of the entire surface included in the zone of destruction and shearing of ice.
