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.
一种可行程自锁的工地手推车,包括:车轮、车身、车轴、三角固定架、自锁机构、复位机构;自锁机构通过三角固定架与车轮与车身相连接,通过自锁机构能够完成手推车在工作过程中允许范围内的任意角度的翻转自锁,整个自锁过程中无需其他驱动装置,提升了手推车的实用性,以及在面对工地各种复杂情况下的适用能力,同时,还能有效的防止卸料过程中对车的反向作用力,保证了施工人员的安全;相比现有技术,齿轮自锁机构还能够对车体翻转的角度保证较高的精准度,并解决了手推车自锁后复位操作繁琐的问题,既在工作效率上有了一定的提高,又能减轻工人的工作量。
