Abstract

A device for loading and unloading cars on a vehicle platform comprising a ladder pivotally mounted at the end of the vehicle platform with the possibility of rotation around a horizontal axis, and a ladder lock in the transport position, characterized in that the ladder is telescopic, in the middle of the main part of which there is a hinge for fastening on a platform, and the sliding part is provided with clamps for two extreme positions.

Description

load and unload the machine

The utility model relates to the field of vehicles (trailers, semi-trailers) for loading and loading, transporting, mainly large-sized, heavy, self-propelled, tracked vehicles (for earthworks, loaders, tractors, etc.) for working with cars, tractors and tractors various types.

A well-known car lift, which contains a hingedly balanced balancer paradise and a tipping mechanism of the said frame, the balancer frame of the elevator is made V-shaped from two branches, one of which contains two articulated "outer and inner parts (I),

Disadvantages of the elevator: it is intended only for lifting and fixing vehicles, use in stationary conditions is not connected with a transporting device and cannot be transported with it to the place of unloading. In addition, there is no possibility to reduce the total length of the balancing frame.

The closest in terms of f-technical severity to the claimed utility model is the well-known 11ZVP railcar ChMZA.EE-8386 containing ladders pivotally mounted at the end of the vehicle platform (with the possibility of turning around horizontally

axis) and ladder locks in transport position (2),

The drawbacks of the known device are: considerable efforts required to set the ramps to the transport position and transfer them to the working position from the transport one, the impossibility of setting them below (or above) the level of the supporting surface of the trailer wheels {high probability of changing the straightness of the moving (unloaded) car (especially caterpillar) ggri Erekhode its wheel bearing surface through an edge, from f; z / f;

dividing the platforms of the trailer platform inclined (loading) from the horizontal (transport), 3fo can lead to an emergency if it is not necessary to support the traction platform and the rollover platform

The declared useful yodel nagts is aimed at solving problems of ensuring the convenience of loading unloading onto a conveyor) platform of mainly large, heavy, self-propelled vehicles with maximum safety.

The technical result is achieved as follows: due to the changing length of the ladder, it becomes important to increase the expensive clearance in the design of the transport platform, create a smaller angle of inclination of the loading ladder relative to the road level, set the ends of the ladder below (or above) the level of the supporting surface of the wheels of the transport platform, reduce the total length of the boards vehicle shape. Due to the unchanged rectilinear movement of the support wheels of the submersible machine along the track of the platform, due to the rotation of the ladder around the axes together with the cage, the maximum safety of loading and unloading is ensured,

The general view of the device is shown, the side view, in FIG. 2, the general view of the device, top view, in §ig 3-section along AA, the articulation of the two parts of the ladder and the platform, in FIG, 2,

The entry device consists of the platform I of the vehicle, in the task of which, with the help of the axes 2, the rotary parts of the ladder 3 are pivotally fixed, the rotary parts of the ladder 3 are interconnected by transverse beams 4, the movable parts of the ladder 5 are telescopically connected to the rotary 3 The movable parts of the ladder 5 can be made of interconnected longitudinal beams in the form of channels and I-beams or pipe B: sliding Shasti of the ladder 5 have bevels b, in addition, in the outer side of the hole 7

z

and on the rotary parts of the ladder, the latches 8 corresponding to them, the sliding parts of the ladder 5 are interconnected by a beam 9, the rotations @ the parts of the ladder 3 have holes 10 in the outer lateral side, and on the platform I there are latches II corresponding to them

The operation of the device is as follows. For loading the machine onto the transport platform I, the sliding parts of the ladder 5 are released from the latches 8 and extend to their maximum possible length. Then they are sealed in this position by the latches 6, After this, the rotary parts of the ladder 3 are released from the latches 3 The movable parts of the ladder 5 outweigh the rotary 3 and with them rotate around the axes 2, Е Having adopted the working position (§ig L) at which the bevels 6 are set to level soil, even if it is lower (or higher) than the level of the bearing surface of the wheels of the transport platform I fi entry of the immersed machine onto the sliding parts of the ramp 5 in a straight line along the track along transport platform I, it will retain this direction of movement the front parts of the ladder 3, A, when the support wheels and then the center of gravity of the machine pass through the axes 2, it will smoothly rotate together with both parts of the ladder to their extreme horizontal position in platform I until the upper surface coincides the ladder with the upper plane of platform I, In this case, the straightness of the movement of the machine along the transport platform ash I remains unchanged After loading the machine on platform I, the gate parts of the ladder 3 are fixed with clamps II, and the sliding parts of the ladder 5 are maximally retracted 3 in the rotary and fixed Xia retainers 8 in the transport position

 unloading the machine from the transport platform I, the sliding parts of the ladder 5 are released from the latches 8, the maximum extension

they are locked and locked again in this position by the latches 8. Next, the rotary parts of the ramp 3 are released from the latches. But the loaded machine starts moving towards the rear of the platform I. After the supporting wheels of the cars, and then the center of gravity, pass through axes 2 , it slowly, as it moves, together with both parts of the ladder begins to rotate around axes 2, the straightness of the movement of the machine along the transport platform I and the ladder remains unchanged The turn of the ladder will continue until its extreme parts come into contact 6 with the level of the surface on which it is necessary to unload the machine This level may be lower (or higher) than the level of the bearing surface of the wheels of the transport platform 1 After the machine is seeded from the ramp, its sliding parts 5 are released from the latches 8 and are pushed into the turning parts by 3 features, as you move in the motion: the parts of the ladder b to the rotary 3, the latter will begin to outweigh the sliding parts 5 with respect to the axles 2 and rotate around them together with the sliding parts of the ladder 5, tending to horizontal shelving, therefore, facilitating their distant Further entry into the rotary parts 3 When the rotary parts of the ladder 3 fully occupy a horizontal position relative to platform I, their upper surfaces are level:; they are attached to the upper plane of the platform I, they are fixed by the latches II. Then they are finally retracted into the sliding parts of the ladder 5 and secured by the latches 8 in the transport position.
