Description

The invention relates to reloading platforms for loading and unloading automobiles.

The purpose of the invention is to increase efficiency.

Figure 1 shows a self-aligning ramp, general view; on fchg ,. the same in the working position; fig.Z - node 1 in figure 1; figure 4 view And fig.Z; fig.Z - node P in figure 1; figure 6 - node W figure 1

The self-supporting ramp consists of a turntable 1, two pairs of V-shaped supports, each of which is formed by levers 2 and 3, and a rod 4 connected by clamps 5,

At the end of the rod 4 there is a buffer stop 6. Inside the rod 4 there is mounted a stopper 7 in the form of a rod hinged to the lever 2 in the groove 8 of the bracket 9 fixedly mounted on the platform 1. On the axis in the groove 8 of the bracket there are gears 10 and 11 with the possibility of contact with the teeth of the rail 12 mounted on the bracket 9.

The stopper 7 is spring loaded spring 13. One end of the stopper 7 has a pin 14 with a protrusion 15 on the inner surface that interacts with the gear wheel 11. The inclined lever 3 is hinged to the stop 16 with one end. The hinge connecting the levers 2 and 3 with the axis 17 is located in the groove 18 of the stand 19 with the possibility of horizontal movement and spring-loaded relative to it by the spring 20, Podstaka 19 is hingedly attached to the base 21 and spring-loaded by the spring 22. The stand 19 includes a switch 23 with the possibility of contact with the switch 24 fixed on the shaft IAOD.

Ramp works as follows.

In non-working position ramp name., Levers 2 and 3 in the groove of the stand

The loading height is greater than the loading height of any car or other vehicle. In this case, the platform 1 by the force of the springs 20 acting on the axis 17 of the connection of the inclined levers 2 and 3,

to the right, the movement of step 4, together with the lever 2 and the single lift of platform 1, is taken up to the initial position. When the stopper 7 is pressed and locks the position of the platform 1.

rises to the extreme upper position, limited by the right edges of the grooves 18 and 8, in which axes 17 and the hinges connecting the stopper 7 to the lever 2 abut.

When backing up to the ramp, the vehicle 25 with the end of its frame interacts with the buffer stop 6 and begins to press the stopper 7, overcoming the force of the spring 13. In this case, the protrusion 15 of the trunnion 14 and the toothed wheel 11 gains freedom to rotate .. After the stopper 7 is fully depressed, the vehicle 25 begins to move the rod 4 due to the pressure transmitted to the buffer stop 6. The movement of the rod 4 is accompanied by turning the gear wheel 10 along the rail 12. At the same time, the angle between p Levers 2 and 3, which causes the platform 1 to lower until it does not lie on the floor of the vehicle 25. Further movement of the vehicle 25 causes the support 19 to rotate relative to the base with levers 2 and 3, accompanied by compression of the spring 22. In this case, the switch 23 presses the switch 24, which, for example, turns on a light signal indicating to the driver of the vehicle 25 that the stationary self-adjusting ramp is set to the working position and that the vehicle’s advancement is necessary ratit.

To bring the stationary self-aligning ramp to the initial (inoperative) position after the end of loading and unloading operations, the vehicle moves away from it. The departure of the vehicle 25 provides movement

to the right side, moving the rod 4 together with the lever 2 and simultaneously raising the platform 1 to the initial position. In doing so, the stopper 7 is pressed and fixes the position of the platform 1.
