Abstract

FIELD: machine building.

SUBSTANCE: invention relates to transport engineering, in particular to transport safety devices when moving on the ice of a water surface. To insure the vehicle on ice, it contains remote skid support in the form of skis mounted on the end of the brackets, which are movably connected to the transport frame, which are fixed in relation to the frame in the tilted position. In the case of destruction of ice under the propellers of transport, outriggers, which are outside the zone of destruction of the ice cover, assume a load of transport weight.

EFFECT: higher traffic safety is achieved.

Description

The technical solution relates to transport engineering, in particular to devices for transport insurance when moving on the ice of a water surface.

A means of insurance of automobile cranes is known through the use of outriggers, which are made by installing swivel ends on the frame of the brackets with free ends resting on a rigid support element [1].

The disadvantage of this technical solution is the impossibility of its use for moving vehicles.

The purpose of the proposed technical solution is to insure the vehicle during movement on ice of the water surface in case of destruction of the ice cover in the area of contact (tracks, wheels) of vehicles with ice.

Achieving this task is achieved by the fact that in a transport containing outriggers mounted on the end of the brackets movably connected to the transport frame, the supports are made in the form of sliding supports (skis) and are removed from the contact area (tracks, wheels) of the vehicle movers with the surface, distance, not less than 1/5 of the track gauge of the propulsors. Moreover, the sliding bearings are connected with their brackets by means of elastic elements with the possibility of rotation relative to the bracket.

In FIG. 1 shows transport with supporting elements when moving along a dirt surface and on ice with a dashed line;

in FIG. 2 is a top view of a transport with hinged brackets when installing a sliding support on two brackets;

in FIG. 3 is a top view of the installation of supports on individual brackets;

in FIG. 4 is a view A in FIG. 3, the attachment point of the sliding support to the bracket using an elastic element;

in FIG. 5 - hinged mechanism of the bracket using a hydraulic cylinder.

The insurance method (Fig. 1) of the vehicle 1 includes hinges 2 connected to the transport frame 3, swivel brackets 4, (Fig. 5) a power drive 5 for turning the bracket 4, sliding bearings 6, (Fig. 4) elastic elements 7, the hinge connecting the bracket with the elastic element 8. Moreover, the sliding supports are placed on the bracket so that when the bracket is tilted, the distance Lop from the inner edge of the support 6 to the outer edge of the track 9 of the propulsion device was at least 1/5 of the track gauge of the propulsors Lк, where for the track width of the propulsors 9 accepted distance between externally and the edges of the track vehicle propulsion.

The method of insurance works as follows.

For the movement of transport 1 on the ice of the water surface, the supports 6 fixed relative to the bracket 4 are released (fur. Not a decree), then the brackets are tilted manually (or by means of a hydraulic actuator 5, if they are present in the structure) and fixed relative to the frame 3, so that the supports 6 lightly touched the ice surface.

When transport 1 moves on ice, especially freight or a freight caravan, the ice may not stand in some places, and transport may fail, creating a threat to people's lives and the loss of material assets available in transport, especially during the development of the Arctic.

In such extreme cases, the transport, falling through, rests on the folding supports, taking the load of the vehicle weight, which, being outside the area of the destroyed ice cover, can hold the vehicle, preventing it from falling under the ice, and the farther the supporting elements are removed from the track of the propulsion vehicles, the higher the reliability of insurance. The presence of sliding bearings makes it easier to tow a jammed vehicle to a safe place.

Using the proposed technical solution will improve the safety of vehicles on the ice of the water surface, avoiding human losses and material values.

The design of the individual nodes given in the description does not exhaust other possible options for its execution and use. For example, outriggers can be installed at the end of the retractable beams moving in the rails connected with the frame, which will be brought into the working position at the right time by the driver or automatically by the power drive.
