Abstract

A new crane, the crane being provided with a lattice boom unit (3) and a box-type telescopic boom unit (4), wherein the box-type telescopic boom unit (4) serves as a mast. A winch system of the crane comprises a first hoisting winch (6), a variable-amplitude winch (7) and a second hoisting winch (8), wherein a steel wire rope led out from the first hoisting winch (6) is led to the top of the lattice boom unit (3) and is wound around a main lifting hook (10) to be used as a main hoisting system; and a steel wire rope led out from the second hoisting winch (8) is led to the top of the box-type telescopic boom unit (4) and is wound around an auxiliary lifting hook (11) to be used as an auxiliary hoisting system. The crane integrates a lattice boom crane and a telescopic boom crane, and can adapt to different engineering requirements; in addition, the crane can be used as a lattice boom crane or a telescopic boom crane on the basis of requirements, and can also have the hoisting functions of both the lattice boom crane and the telescopic boom crane at the same time, thereby improving the boom lifting capacity of the whole crane and the apparatus utilization rate, and reducing procurement and operation costs.

Abstract

A crane, comprising: a chassis (11), a rotating table (12), a mast (13), a boom (14) and a luffing mechanism (20). The rotating table (12) is rotatably arranged on the chassis (11), both the mast (13) and the boom (14) are rotatably arranged on the rotating table (12), the mast (13) is connected to the boom (14) through a second tensioning member (15), and the luffing mechanism (20) is arranged on the rotating table (12) to implement luffing of the boom (14). The luffing mechanism (20) comprises: a connecting frame (21) arranged on the rotating table (12); a guide pulley assembly (22) arranged on the connecting frame (21); a luffing pulley assembly (23) arranged on the rotating table (12) and lower than an arrangement position of the guide pulley assembly (22); and a pull rope drive component (24) configured to draw out and drive a luffing pull rope (25) connected to the mast (13) and wind the luffing pull rope (25) around the guide pulley assembly (22) and the luffing pulley assembly (23).

Abstract

The present disclosure relates to the technical field of engineering machinery, and relates to a path planning method and apparatus, and a crane. The path planning method comprises: acquiring an environment image of a vehicle during traveling; processing the environment image by using a trained target detection model, so as to identify an obstacle in the environment where the vehicle is located; when an environment point cloud corresponding to the environment image is acquired and a system performance indicator meets a preset condition, determining a spatial position of the obstacle by using the environment point cloud corresponding to the environment image; and adjusting an initial traveling path of the vehicle according to the current position of the vehicle, the spatial position of the obstacle and a target position of the vehicle.

Abstract

The present application relates to the field of lifting equipment, in particular to a crane and a control method thereof. The crane includes: a body including a chassis and a turntable being rotatably arranged on the chassis; a super-lift device including a super-lift jib, a suspension pulling member and a balancing mechanism, the balancing mechanism including a super-lift counterweight and a pushing device, first ends of the super-lift jib and the pushing device being both connected to the turntable, the suspension pulling member being connected to a second end of the super-lift jib and the super-lift counterweight, a second end of the pushing device being connected to the super-lift counterweight to adjusting a distance between the super-lift counterweight and a slewing center of the turntable; and a hovering device configured to support the super-lift counterweight above a ground when the crane is under no load, a first end of the hovering device being connected to the turntable and a second end of the hovering device being not connected to the super-lift jib. Based on this, the function of slewing and traveling of the crane under no load while carrying the super-lift counterweight is achieved more conveniently.

Abstract

A crane and a control method therefor, wherein the crane (10) comprises: a body (1) comprising a chassis (11) and a turntable (12), the turntable (12) being rotatably disposed on the chassis (11); a super-lift device (2) comprising a super-lift arm (21), a suspension traction member (26) and a balance mechanism (2a), the balance mechanism (2a) comprising a super-lift counterweight (22) and a pushing device (23), first ends of the super-lift arm (21) and the pushing device (23) being both connected to the turntable (12), the suspension traction member (26) being connected to a second end of the super-lift arm (21) and the super-lift counterweight (22), a second end of the pushing device (23) being connected to the super-lift counterweight (22), and the distance from the super-lift counterweight (22) to the rotation center of the turntable (12) being adjusted; and a hovering device (3) used for supporting the super-lift counterweight (22) above the ground when the crane (10) is unloaded, a first end of the hovering device (3) being connected to the turntable (12), and a second end of the hover device (3) being not connected to the super-lift arm (21). On this basis, the function of the crane (10) to drive the super-lift counterweight (22) to rotate and travel in an unloaded state can be more conveniently achieved.
