Description

Technical Field

[0001] The invention belongs to the field of transportation tools, and in particular relates to a turnover frame of a standard container transportation tool. Background Art

[0002] In the field of cargo transportation, container transportation has become the first choice for efficient, long-distance and intensive transportation. In addition, the existing freight boxes have the function of self-unloading, which has made outstanding contributions to improving the efficiency of cargo transportation, especially bulk cargo transportation. In the actual application process, some special situations will be encountered. For example, in mountainous areas, the roads are more uphill and downhill, which poses a challenge to the use of self-unloading containers for bulk cargo transportation. The reason is that most self-unloading freight boxes (containers) adopt the form of tail self-unloading. Therefore, when the freight box is loaded on the skeleton car, the freight box must be loaded on the tail of the skeleton car, so that when it arrives at the freight destination, the rear door is automatically opened, the front end of the freight box is lifted, and the freight box is tilted backward, and the bulk cargo is discharged from the rear door to realize the self-unloading function. However, when the skeleton car loads the freight box to the tail of the skeleton car, the front end of the skeleton car is tilted, especially in the uphill stage, the skeleton car loses pressure on the driving wheels of the tractor, and the driving wheels of the tractor lose adhesion to the ground, and also lose driving force, resulting in a greatly reduced climbing ability of the tractor, or even the inability to realize the climbing function. Summary of the invention

[0003] In view of the above-mentioned problems encountered by freight boxes during transportation, the present invention proposes a freight box that can not only meet the requirements of the freight box having a self-unloading function, but also meet the requirements of the freight box maintaining pressure on the front end of a skeleton vehicle, that is, on the driving wheel of a tractor.

In this example, two middle cross beams 10 are selected for parallel installation; the front support rollers 11 are installed at both ends of the middle cross beam 10 and connected to the middle cross beam 10. The installation position corresponds to the position of the bottom load-bearing beam of the container carried, which can withstand most of the weight of the container and transmit it to the frame 9 and the longitudinal beam 1 of the skeleton vehicle; in this example, a multi-stage single-acting hydraulic cylinder commonly used in the industry is selected as the lifting cylinder 12, which can reduce the volume under the same lift; the lifting cylinder 12 is installed on the cylinder seat 5 and is hinged to the cylinder seat 5 through the lifting cylinder seat 13; the lifting cylinder The cylinder seat 13 is installed on the cylinder seat 5, connected to the cylinder seat 5, and is fitted with the installation pin of the lifting cylinder 12. In this example, the lifting cylinder seat 13 is selected as a quick-clamping articulated seat, so that the lifting cylinder 12 can be quickly separated from the skeleton car; the limit pin 14 is installed on the flip shaft 16 and connected to the flip shaft 16.
