Problems solved by technology
[0005] However, in the process of using the utility model of the above example, it was found that the construction site trolley can only play a certain role in the tilting of the body hopper, but during the tilting process, it cannot realize the self-locking function, and it needs to be manually held continuously, which does not meet the actual operation on site. Therefore, we urgently need to invent a construction site trolley that can realize self-locking function during use to solve the above problems

The invention relates to a construction site trolley capable of achieving stroke self-locking. The a construction site trolley comprises wheels, a trolley body, an axle, a triangular fixing frame, a self-locking mechanism and a reset mechanism. The self-locking mechanism is connected with the trolley body through the triangular fixing frame and the wheels, overturning and self-locking of the trolley at any angle within the allowable range in the working process can be completed through the self-locking mechanism, other driving devices are not needed in the whole self-locking process, the practicability of the trolley is improved, and the application capacity of the trolley under various complex conditions of a construction site is improved. Meanwhile, the reverse acting force on the vehicle in the discharging process can be effectively prevented, and the safety of constructors is guaranteed; compared with the prior art, the gear self-locking mechanism can further guarantee high accuracy of the overturning angle of the trolley body, the problem that reset operation is complex after the trolley is self-locked is solved, the working efficiency is improved to a certain extent, and theworkload of workers can be reduced.
Description
technical field [0001] The invention relates to the technical field of construction equipment, in particular to a traveling and self-locking construction site trolley. Background technique [0002] The trolley is a transport vehicle that is pushed and pulled by manpower. It is the ancestor of all vehicles. Although the material handling technology is constantly developing, the trolley is still used as an indispensable transport tool. The construction site trolley is widely used in production and life because of its low cost, simple maintenance, convenient operation, light weight, and because of the complex and harsh environment of the construction site, the construction site trolley can work in places where motor vehicles are inconvenient, saving a lot of manual labor , to speed up the work efficiency of workers, it is still an indispensable part of the construction site so far; [0003] However, with the rapid development of the country's infrastructure, construction site ...
