[0018] The present application will be further described below in combination with the embodiments thereof and the accompanying drawings. EMBODIMENT

[0019] The back support structure for roof operation of a truck crane of the present application comprises a roadbed plate 1.

[0020] Please refer to FIG. 1 Figures 1-3As shown in the figure, the back supporting structure for the automobile crane roof operation needs to be set at each leg position station of the automobile crane. The basement roof 6 and the automobile crane leg contact part are provided with a roadbed plate 1, and the size of the roadbed plate 1 is 2mx2m. The support column 2 is provided with three round steel pipes, and the specification of the round steel pipe is P299x8mm. The arrangement form is triangular arrangement. The triangular arrangement can disperse the force when bearing the gravity and external force, and provide more stable support. The support column 2 is flush with the top base plate 5, so that the cross section of the support column 2 bears the force uniformly. The top base plate 5 and the bottom base plate 3 are both iron plates with a thickness of 20mm. The bottom of the support column 2 and the bottom base plate 3 are adjusted by the wedge blocks 4. The wedge blocks are arranged in a uniform interval along the outer periphery of the bottom base plate 3. After the support column 2 is connected with the basement roof 6 tightly by adjusting the wedge blocks 4, the support column 2 and the bottom base plate 5 are fixed by welding. The stress principle of the support structure is that the basement roof 6 and the raft 7 are connected by the support column system to form a support system, so as to provide the required bearing capacity for the automobile crane construction on the basement roof.
