Detailed Description

Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

as shown in fig. 1 and 2, the truck with the mechanical arm comprises a large truck 1, support legs 2, a base 6 and a mechanical arm 10, wherein the base 6 is arranged on a chassis 5 at the tail of the truck 1, a plurality of support legs 2 are arranged on two sides of the chassis 5 of the truck 1, telescopic frames of the support legs 2 at the tail of the truck 1 are arranged on the base, and other support legs are connected with the chassis 5 of the truck 1 through the telescopic frames 3. The telescopic frame 3 adopts movable connection modes such as a slide way, a thread and the like to realize the telescopic effect. Landing leg 2 is also connected with modes such as telescopic bracket screw thread to realize raising and lowering functions, stretch out the stability automobile body and reduce the tire atress when hoist and mount state, guarantee the stability of freight train 1. The mechanical arm 10 comprises a driving part 8, and a base rotary support 7, a main arm 15, a folding arm 12, a front and rear swing part 24, a left and right swing part 20, a hanger rotary support 21 and a hanger 9 which are connected in sequence. The main boom 15 includes a base boom 14, a telescopic boom 13, and a telescopic cylinder 18, and the telescopic cylinder 18 drives the telescopic boom 13 to extend from or retract into the base boom 14.
