RU91343U1 - DEVICE FOR REMOVING SNOW-ICE FORMATIONS FROM ROAD COVERINGS - Google Patents

Abstract

A device for removing snow and ice formations from road surfaces, mainly instead of brushing equipment for cleaning machines, including a working drum with cutters and a drive, characterized in that the working drum is made of three disks on the drive shaft and five axes installed through these disks , with a lot of incisors staggered in the deployed position of the drum, and the incisors are freely mounted on the axes with a negative clearance relative to the work surface, for example, from 20 d 40 mm, with the possibility to use the inertial action of cutters for removing snow and ice formations.

Description

The invention relates to machines for cleaning roads from ice, to equipment for the winter maintenance of roads, airfields, etc.

A device is known for removing snow and ice formations from pavements (ed. St. USSR No. 1539256, class E01H 5/12 of 05/06/1988). The device comprises a base chassis with a heat generator installed on it, having a pulsating-type combustion chamber with an exhaust manifold connected to a resonant tube, gas pipelines communicated at one end with the latter and mounted axially movable with a frame on which a horizontal shaft with disks is mounted . The device is equipped with burners having inclined and vertical channels, rigidly attached to other ends of the gas pipelines, which include two external and internal pipelines installed coaxially and with a radial clearance, each of which is made in its upper part with slots for communication with the gas distribution holes installed in the resonance tube, and in the lower part the inner pipeline is in communication with the inclined torch channels, the outer one with vertical channels, while the gas pipelines are installed with the possibility of axial rotation of the drive at an angle of 90 °. And the gas pipeline turning drive includes a gear drive kinematically connected with gears, which are rigidly fixed to external pipelines. The burners in the plan are made rectangular, their width is not more than the width of the cutting disc and installed in the transverse plane without a gap.

The disadvantage of this device is its high material consumption and energy intensity.

According to patent RU 2019621 of 12.26.1990, there is known a device for removing snow and ice formations from road surfaces, comprising a frame, a hopper with a vacuum pump and a magnetostrictive transducer mounted on it, including a housing with vertical channels communicating the hopper with a zone below the working surface of the housing, magnetostrictive elements are mounted on the housing. The body is hollow. The channels are formed by pipes fixed in the housing. And magnetostrictive elements are formed by packages of plates located in vertical planes and attached between the tubes and the body, providing radiation parallel to the axis of the tubes.

However, this device is of complex construction.

The invention solves the problem of simplifying the design and improving efficiency in the work.

The technical result achieved by the invention is to increase the efficiency of the device when removing snow and ice formations from road surfaces with a simplified design.

The specified technical result is achieved by the fact that the device includes a working drum with cutters and a drive, mainly instead of brushing and sweeping equipment for harvesting machines. The working drum is made of three disks on the drive shaft and five axes mounted through these disks, with many incisors staggered in the unfolded position of the drum. The cutters on the axes are mounted freely with a negative clearance relative to the surface being machined, for example, from 20 to 40 mm, with the possibility of using the inertial action of the cutters to remove snow and ice formations.

Figure 1 schematically shows a General view of a device for removing snow and ice formations from road surfaces, figure 2 schematically shows a scan of the device, figure 3 is a fragment of the cutter.

The device consists of a working drum 1 of, for example, 3 disks 2, through which axles 3 are installed, for example, in an amount of five, axes 3 are placed cutters 4 in a checkerboard pattern with the deployed position. A drive, for example, a hydraulic motor 5 with a drive shaft 6, is mounted on the supports 7 of a harvesting machine (not shown).

A device for removing snow and ice formations from road surfaces works as follows. It is installed instead of the brushing and sweeping equipment on the base chassis of the sweeper in the supports 7. A machine with such a device is installed on a section of the roadway from which it is supposed to clear ice or compacted snow. The drive 5 is turned on and by means of the drive shaft 6 the drum 1 with the disks 2 and the axles 3 with the cutters 4 is rotated, in contact with the surface of the roadway, cleans it. The effect in this case is obtained due to the fact that the cutters 4 are freely mounted on the axes 3 with a negative clearance in relation to the work surface, for example, from 20 to 40 mm. Moreover, the inertial action of the cutters 4 is used to remove snow-ice formations.
