Automatic leveling device for conveying platform and loading machine

Abstract

The invention relates to the technical field of airport ground equipment, and particularly relates to an automatic leveling device for a conveying platform and a loading machine. The automatic leveling device for the conveying platform comprises a main platform and a bridge platform, and an automatic leveling mechanism is arranged between the main platform and the bridge platform; and the automatic leveling mechanism comprises baffles, a supporting plate, a low-position sensor, a leveling sensor, a high-position sensor and an ultrahigh shutdown protection sensor, at least one baffle is arranged between the main platform and the bridge platform, the supporting plate is arranged on the main platform, one end of the supporting plate is exposed out of the main platform and arranged below the baffles, and the baffles are hinged to the bridge platform. One end of each baffle faces the supporting plate and is provided with a low-position sensor, and a following sensor, a leveling sensor, a high-position sensor and an ultrahigh shutdown protection sensor are arranged between the other end of the baffle and the bridge platform. The loading machine comprises a chassis, and the automatic leveling device for the conveying platform is arranged on the chassis. The butt joint height of the main platform and the bridge platform is consistent, butt joint is stable and safe, and the cargo conveying efficiency is high.

[0002] Container cargo loaders are widely used in major airports. Existing loaders generally include a chassis, a vehicle PLC controller, a lithium battery power unit, and a driving motor. The vehicle PLC controller is used to control an electric airport container cargo loader. Work, the chassis is connected with the front axle and the transmission platform, the transmission platform includes the main platform and the bridge platform, the main platform is equipped with a transmission motor, chain, transmission roller and motor controller, and the bridge platform is equipped with a transmission motor, chain, transmission roller and motor The controller, the main platform and the bridge platform are docked to complete the cargo delivery. For example, the Chinese patent CN214059744U discloses a kind of electric aircraft assembly lifting platform vehicle, which is characterized in that: it includes a vehicle frame, an operating console, a main platform, a bridge platform and a power part. , the power part includes a battery compartment, a main motor, a regenerative motor, a travel motor, a first hydraulic pump, a second auxiliary hydraulic pump, a hydraulic motor, and an inverter. The main platform and the bridge platform are respectively provided with crawlers and ten thousand The steering wheel, the operating platform is fixed on the bridge platform, the vehicle frame is connected to the main platform through the first lifting mechanism, and the vehicle frame is connected to the bridge platform through the second lifting mechanism, The first lifting mechanism drives the main platform up and down, and the second lifting mechanism drives the bridge platform up and down. When in use, the first lifting mechanism of the main platform lifts the main platform to the bridge platform. The position of the same height, docking with it, realizes the delivery of goods. The shortcomings of the above patents and the prior art are: first, the main platform and the bridge platform can be docked only after the lifting height of the lifting mechanism is the same, but the height of the main platform and the bridge platform It requires multiple adjustments to be consistent, which is time-consuming and labor-intensive, which indirectly leads to low cargo transmission speed; second, when the height of the main platform and the bridge platform are inconsistent, the cargo transmission is easy to get stuck, affecting the transmission efficiency, and the goods may be thrown out; the third is that the main platform is in the During the lifting process, if there is no limit and the rising speed is too fast, the main platform may overturn the bridge platform and hit the plane
