Abstract: An integral rescue accessory for forcible entry and core drill may include hydraulic wall saws, a rotating platform, and a coring claw. Two hydraulic wall saws are symmetry installed on rotating platform. The wall saws cut linearly with the rotation of rotating platform to open a rectangular tunnel on a reinforced concrete wall or floor. After the cutting process, coring process is finished by the wall saws and claw inclinedly mounted to ensure the security of rescue. The whole accessory is installed on a large engineering machine through a hydraulic joint. The present disclosure can transfer general large mechanical equipment into dedicated large mechanical equipment quickly.

Abstract: A multifunctional engineering accessory with 6-bar mechanism comprising: a 6-link rod clamping device, a shear-fork separation device, a shearing device and locking device. Motion and lock of the 6-link rod group are implemented through a swing hydraulic cylinder of the 6-link rod clamping device to implement extending and withdrawing processes of a clamping paw. The shear-fork separation device can separate an accessory holder to meet the lateral dimension requirement of the multifunctional accessory. The shearing device can implement shearing and crushing function of multifunctional accessory, and the motion location of the accessory holder is confirmed by locking device while at the same time it sustains counterforce generated when the multifunctional accessory is working. The hydraulic ram is the power supply of the whole device. The present disclosure combines shearing, crushing and clamping on one accessory, and the structure design is a novelty, the driven pattern is reasonable, and the manufacturing technology is simple and easy to operate. The device can implement the crushing and moving processes of ruins better, while at the same time improving the economic efficiency.
