The invention discloses a locking device and an engineering machinery vehicle, and relates to the technical field of engineering machinery vehicles. The locking device is used for locking a first mounting part and a second mounting part which are matched with each other, the locking device comprises a hydraulic cylinder, the hydraulic cylinder comprises a cylinder body and a piston rod, the piston rod is slidably arranged in the cylinder body through a piston, and a locking hook is arranged at the end, away from the piston, of the piston rod; the cylinder body is fixed to the first installation piece, the first installation piece and the second installation piece are located between the cylinder body and the locking hook after being matched, the piston rod shrinks, and the locking hook can abut against the second installation piece so as to lock the first installation piece and the second installation piece; and when the piston rod extends, the locking hook is separated from the second mounting piece, so that the first mounting piece and the second mounting piece are unlocked. The first mounting piece and the second mounting piece between the cylinder body and the locking hook can be locked and unlocked by controlling the piston rod to contract and extend, so that the first mounting piece and the second mounting piece are quick and convenient to disassemble and assemble, and are safe and reliable.

    本发明公开了一种锁紧装置及工程机械车辆,涉及工程机械车辆技术领域。该锁紧装置用于将相互配合的第一安装件和第二安装件锁紧,锁紧装置包括液压缸,液压缸包括缸体和活塞杆,活塞杆通过活塞滑设于缸体内,活塞杆远离活塞的一端设置有锁紧钩;缸体固定于第一安装件上,第一安装件和第二安装件配合后位于缸体和锁紧钩之间,活塞杆收缩,锁紧钩能与第二安装件抵接,以将第一安装件和第二安装件锁紧;活塞杆伸长,锁紧钩与第二安装件脱离抵接,以使第一安装件和第二安装件解除锁紧。通过控制活塞杆收缩和伸长,能将位于缸体和锁紧钩之间的第一安装件和第二安装件锁紧和解除锁紧,使得第一安装件和第二安装件拆装快速方便,且安全可靠。
