Trailer provided with support devices

Abstract

The invention relates to special vehicles, in particular to a trailer provided with support devices. The trailer comprises a chassis truck provided with a frame and side wall assemblies, wherein the frame is provided with the support devices, each support device comprises an inner sleeve and a landing leg, and a fixing block is arranged on the landing leg; a T-shaped block is mounted on an end surface of each inner sleeve, a hole in the T-shaped block is nested in a hole in the fixing block; first limiting pins and second limiting pins are mounted on the frame; a third limiting pin is mounted on each fixing block; a round hole which allows the first limiting pin to be nested is formed in one side of each inner sleeve, and a long-strip-shaped hole allowing the second limiting pin to be nested is formed in the other side of each inner sleeve. Compared with the prior art, the trailer is maneuverable, small and flexible, the obstacle passing capability and the bearing capability of the trailer are met, the stability and the shock absorption of equipment on the trailer during running can be guaranteed, the tires can be protected from deformation by external force during long-time parking of the trailer, and the service life of the tires is prolonged.

Description

technical field [0001] The invention relates to a special vehicle, in particular to a trailer with a supporting device. Background technique [0002] At present, with the improvement of living standards, cars have become a common means of transportation and means of transportation in people's daily life, and self-driving travel has become a normal state in people's lives; Luggage supplies are limited, and trailers have become more and more a means of transportation for people to travel because of their flexibility and the ability to carry heavy cargo. In addition, with the industrialization of cities and people paying more and more attention to the protection and utilization of natural environmental resources, in the actual use of trailers, they are not only satisfied with carrying general goods, but more and more trailers are equipped with various A variety of emergency equipment required for emergency rescue and relief, such as generator sets, water pumps, alarm equipment...

AI Technical Summary

Problems solved by technology

[0003] However, most of the trailers on the market are not equipped with supporting devices, which easily causes the trailer to shift when the equipment on the trailer (such as the generator set) is running; When the trailer is parked for a long time, it bears the heavy pressure of equipment and goods, which will easily cause the trailer tires and shock absorbing springs to be deformed by one-way force for a long time, which will affect their service life and bring hidden dangers to the safety performance of the trailer.

In addition, a small number of types of trailers on the market, such as the trailer patent announced by Chinese patent CN102806953 A, although there are support devices installed, these support devices are all fixed in structure, directly installed on the vehicle frame, and cannot be adjusted and adjusted. Shrinkage affects the accessibility of the trailer; and if the center of gravity of the equipment and goods on the trailer is high, when the equipment on the trailer (such as a generator set) is running, the supporting device has a small load-bearing area and it is easy to cause the trailer to roll over
