Portable lengthened loading ramp

Abstract

The invention provides a portable lengthened loading ramp. The portable lengthened loading ramp comprises a lifting platform and sliding guide wheels located at the front end of the lifting platform, and further comprises eight supporting legs arranged on two sides of the lifting platform. The supporting legs are evenly distributed on two sides of the symmetrical positions of the longitudinal axis of the lifting platform. Each supporting leg is provided with a plurality of telescopic cylinders sequentially connected in a sleeving mode, wherein the telescopic cylinder on the outermost layer is connected with the lifting platform through a connector device, a steering wheel and a traveling wheel are installed under the telescopic cylinder on the innermost layer, and the telescopic cylinders can stretch out and draw back vertically synchronously or in a grouped mode. The portable lengthened loading ramp further comprises a lifting platform automatic leveling control device used for automatically detecting and adjusting the length of the telescopic cylinders so that the supporting legs can be stressed in a balanced mode. Multiple portable lengthened loading ramps can be connected in series for work and can load ultra-long cargos. The portable lengthened loading ramp has the characteristics of being simple in structure, light in weight and easy and convenient to operate, and can automatically get on and off various conveyers and be carried along with the conveyers, the maneuverability and loading and unloading efficiency of the conveyers are improved, and the comprehensive conveying cost is lowered.

Description

technical field [0001] The invention relates to the field of aviation ground loading and unloading support equipment, in particular to a portable elongated cargo bridge, which solves the problem of fast loading and unloading of large-length and large-volume material equipment by military transport aircraft, and is carried with the aircraft. Background technique [0002] Because the configuration of the ramp-type rear hatch of military transport aircraft cannot load large-length and large-volume materials and equipment, at present, when domestic and foreign military transport aircraft load large-length and large-volume materials and equipment, they are all used at the departure and destination airports. An extended cargo bridge is set up on the ground in advance, and the vehicles pull large-length and large-volume materials and equipment to the extended cargo bridge outside the cabin, and the loading and unloading operations are carried out horizontally aligning the cabin.

Problems solved by technology

[0002] Because the configuration of the ramp-type rear hatch of military transport aircraft cannot load large-length and large-volume materials and equipment, at present, when domestic and foreign military transport aircraft load large-length and large-volume materials and equipment, they are all used at the departure and destination airports. An extended cargo bridge is set up on the ground in advance, and the vehicles pull large-length and large-volume materials and equipment to the extended cargo bridge outside the cabin, and the loading and unloading operations are carried out horizontally aligning the cabin. This loading method results in long preparation period, large investment, low efficiency, and affects flight. The problem of mobility; in order to improve our military’s long-range strategic air projection capabilities, achieve wider global military power projection, and meet the requirements for fast loading and unloading of large-length and large-volume material equipment, it is necessary to solve the traditional lengthening of the ground. Carrying and quick installation and disassembly of cargo bridges to implement loading and unloading operations quickly and conveniently
