Folding type mobile car lifting jack

Abstract

The invention discloses a folding type mobile car lifting jack, and the structure thereof comprises a plurality of drive axles, lifting boxes which are matched with the number of the drive axles, a central drive box, universal wheels which are matched with the number of the drive axles, a braking structure, fixing rods with the number being twice of that of the drive axles. The invention has the beneficial effects of no need to rely on an external source, simple, convenient, speedy and safe operation, high efficiency of lifting and moving, small occupied road area when sheering off and turningaround, easy carryover on the car, and capability of effectively solving the problem that the car can not be out of traffic jam on the condition of front and back traffic jam and also solving the noise pollution problem caused by whistling and the like during the traffic jam.

Description

technical field [0001] The invention relates to a car lifting and moving technology, in particular to a foldable mobile car lifter. Background technique [0002] At present, the number of cars in the world is nearly 1 billion, and it is still increasing. In contrast, the development of roads and the construction of urban infrastructure are relatively lagging behind, failing to keep up with the growth rate of the number of cars; due to my country's recent years The continuous increase of national income leads to the rapid increase in the number of cars and the relatively lagging road construction. This contradiction is particularly prominent in large and medium-sized cities in my country, and it cannot be resolved in a short period of time. [0003] The problems brought about by the rapid growth of the number of cars are not only reflected in the serious congestion and frequent blockage of many urban roads, but also indirectly lead to a serious shortage of parking spaces in ci...

Problems solved by technology

[0002] At present, the number of cars in the world is nearly 1 billion, and it is still increasing. In contrast, the development of roads and the construction of urban infrastructure are relatively lagging behind, failing to keep up with the growth rate of the number of cars; due to my country's recent years The continuous increase of national income leads to the rapid increase in the number of cars and the relatively lagging road construction. This contradiction is particularly prominent in large and medium-sized cities in my country, and it cannot be resolved in a short period of time.

[0003] The problems brought about by the rapid growth of the number of cars are not only reflected in the serious congestion and frequent blockage of many urban roads, but also indirectly lead to a serious shortage of parking spaces in cities and communities. The main problems caused by it have three aspects: First, random parking in the community The phenomenon of non-standard parking, which makes the front and back of the parking space blocked and cannot enter and exit the parking space, has seriously affected the normal travel of community residents, and the resulting noise pollution from cars honking has also seriously affected people's normal life. Harmonious life and neighborhood; second, when there is a traffic jam in traffic, if the distance between the vehicles is very close, it is impossible to drive the blocked vehicles away from the traffic jam, resulting in more and more traffic jams; third, the global oil resources are increasingly scarce, and oil prices It is even more high. According to the survey, the fuel wasted due to traffic jams is astonishing. The value of fuel consumed due to traffic jams in Zhengzhou, Henan Province is as high as 800 million to 1 billion yuan every year. If a city wastes so much, then the whole country and the world because of The fuel wasted due to traffic jams is even more immeasurable. Therefore, the problem of traffic jams and parking difficulties has become a global problem that needs to be solved urgently.

[0004] In order to solve the aforementioned problems, there have been people who have designed lifting devices for mobile vehicles, but this type of device has limited its application due to many reasons, and its limited reasons can be summarized as follows: 1) the existing lifting device The device usually adopts a combination of electrical, hydraulic and mechanical structures, which not only makes its structure very complicated, but also can only work when there is power in the surrounding environment; 2) Due to its complex structure, lifting The lifting device is bulky, and the work site required for use is relatively large, and it also causes great inconvenience to installation and carrying on the vehicle; 3) In order to adapt to its own structural characteristics, some lifting devices must also treat the parts of the moving vehicle. The structure must be modified to make the lifting device work properly

[0005] There is also a kind of lifting device, the purpose of which is to maintain the car after it is lifted. This type of lifting device cannot move after the car is lifted, and it also has the same function as the aforementioned lifting device for moving. Shortcomings
