Abstract

Vynález sa týká odboru dopravy a rieši sklápanie a odklápanie rampového mostíka samočinné bez obsluhy s odvodeným pohonom od vozidla. Vozidlo, cúvajúce s otvorenou ložnou plochou k rampě, tlačí na pružná páku, ktorá přemáhá zdvíhajúcu pružinu mostíka, sklopné uchyteného k rampě a tým ho sklopí na ložná plochu vozidla. Po odchode vozidla pružina rampový mostík vráti do východzej polohy. Menší pokles ložnej plochy vyrovnává napružená páka. Vačšiemu poklesu ložnej plochy zabraňuje stabilizačně zariadenie pod vozidlom. Vynález možno využívat vo všetkých odboroch pri prekládke bremien na vozidlá.The invention relates to the field of transport and solves the automatic folding and unfolding of a ramp bridge without operator with a drive derived from the vehicle. The vehicle, reversing with an open loading area to the ramp, presses on a flexible lever, which overcomes the lifting spring of the bridge, foldable attached to the ramp and thus folds it onto the loading area of the vehicle. After the vehicle leaves, the spring returns the ramp bridge to its original position. A smaller drop of the loading area is compensated by a spring-loaded lever. A larger drop of the loading area is prevented by a stabilizing device under the vehicle. The invention can be used in all fields when reloading loads onto vehicles.

Description

The present invention relates to the field of transport and solves the tilting and tilting of a ramp without automatic operation by the operator.

A vehicle reversing with an open loading platform to the ramp presses on a resilient lever that overrides the lift spring of the bridge, hinged to the ramp, thereby tilting it to the vehicle loading area.

After leaving the vehicle, the spring returns to the starting position.

A smaller drop in the loading area is compensated by the spring lever. A larger drop in the loading area is prevented by the stabilizing device under the vehicle.

The invention can be used in all load translations in vehicles.

The present invention provides a self-acting ramp that serves to transition between a loading ramp and a vehicle-derived vehicle loading platform.

So far known bridges for the transition between the loading ramp and the vehicle loading area are either portable to the handle or hinged around the hinges. Also, complex and expensive machine-specific ramps are known that are unavailable and unused. In both cases, the ramp requires operator either to move or dump into the working position and after loading, the operator must remove the ramp bridge, which is a laborious and mainly unhygienic job.

The aforementioned drawbacks are eliminated by a self-acting ramp bridge on one side hinged to the loading ramp according to the invention, the principle being that a flexible lever is fixedly fixed to the lower bridge part, the free end abutting the rear part of the vehicle and the upper end of the spring, the other end of which is supported fixed to the front of the loading ramp. The reversing vehicle pushes the spring lever over the ramp bridge overcomes the spring preload until the free end of the bridge abuts the vehicle loading area. After loading and unloading the vehicle, the spring lifts the bridge to standby. The advantage of the proposed solution is the automatic folding to the working position when moving the vehicle without the need for energy or live work, while observing the principles of hygiene, 4 which is particularly important in food dispatches.

In the accompanying drawing, an exemplary embodiment of a ramp bridge is shown, wherein in Fig. 1 a ramp bridge without a vehicle is shown and in Fig. 2 a ramp bridge with a vehicle is shown.

On the ramp 1, a bridge 3 is fixed in point 2, on which the spring lever 4 is attached. The bridge 3 lifts the spring 5 from the bottom, which is fixed on the ramp 1 by the other side. at the bottom 7 of the vehicle and the stop 9 of no vehicle wheels.

A vehicle reversing with an open cabinet or with no front facing down pushes the lower housing 7 onto a spring lever 4 which overcomes the spring 5 and hinges the hinged bridge 3 at point 2 by the ramp 1 to the vehicle loading surface 10. The lower drop of the loading surface 10 is compensated by the flexible lever 4. The lowering of the loading surface 10 is prevented by the stabilizing device 8, by which the roller G fixed on the lower part 7 of the vehicle is supported. No vehicle wheels stop 9 secures the vehicle distance from ramp 1. The outgoing vehicle from the ramp 1 runs out of the stabilizing device 8, releasing the spring lever 4, and the spring 5 returns the folding bridge 3 to the initial position.

The self-acting ramp bridge can be advantageously used for loading crates, pallets in food dispatchers, where it is assumed that vehicles are of a uniform type.

Claims

OBJECT Self-acting, ramped, derived vehicle-derived ramp bridge on one side, hinged to the loading ramp, characterized in that a resilient projection of the lever (4) is fixedly fixed to the bottom of the bridge (3), abutting the rear end of the vehicle with the free end an upper end of the spring (5), the other end of which is fixedly secured to the front of the loading ramp. 1 sheet of drawings 232107
