Embodiment 1

[0041]Embodiment 1: A kind of hoisting method of a truck crane, a limit belt is set between the saddle of the rubber suspension system of the truck crane and the equalizing beam or between the equalizing beam and the frame of the truck crane, and the vehicle is completed with the help of the limit belt. Lifting of the crane; the spacer band is subjected to the downward pull of the unsprung mass during hoisting, and the spacer band changes from a relaxed state to a stretched state; when the lifting is completed, the spacer band changes from a stretched state to a relaxed state, The tires of a truck crane bear the downward pull of the unsprung mass. The lifting method at least includes the following steps: 1) When lifting, put down the hydraulic support legs and leave the tires off the ground. At this time, the rubber suspension system of the truck crane is supported by the spring through the limit belt arranged on the rubber suspension system. The downward pulling force of the ...

Embodiment 2

[0046] Implementation 2: If Figures 9 to 10 As shown, compared with Embodiment 1, the only difference is that the assembly lifting lug 9 is only set on the equalizing beam 1, and the limit belt 8 is connected by the assembly lifting lug 9 of the equalizing beam 1 and the lifting lug on the vehicle frame. For the equalizing beam 1 and the vehicle frame, the length 13 of the limiting band 8 is 500mm. The mounting lugs 9 are arranged on the inner and outer surfaces of the equalizing beam 1 . The number of the mounting lugs 9 is four. The material of the position-limiting band 8 is nylon material. The elastic rubber layer 11 and the metal spacer 10 are 4 and 5 layers respectively. The distance 12 between the lowermost end of the limiting block 5 and the uppermost end of the equalizing beam 1 is 140mm. The thrust rod 4 is a straight thrust rod with two horizontal and two vertical arrangements.

Embodiment 3

[0047] Implementation 3: If Figures 11 to 14 As shown, compared with Embodiment 1, the only difference is that the assembly lifting lug 9 is only set on the equalizing beam 1, and the limit belt 8 is connected by the assembly lifting lug 9 of the equalizing beam 1 and the lifting lug on the vehicle frame. For the equalizing beam 1 and the vehicle frame, the length 13 of the limiting band 8 is 800 mm, the assembly lifting lug 9 is arranged on the outer surface of the equalizing beam 1 , and the number of the assembly lifting lug 9 is two. The material of the limiting band 8 is polyester fiber material. The distance 12 between the lowermost end of the limiting block 5 and the uppermost end of the equalizing beam 1 is 70 mm. The thrust rod 4 is a V-shaped straight thrust rod.

[0048] In summary, through the technical solution of the present invention, during the hoisting process, the limiting belt is in a tight state and bears most of the tensile load, so as to ensure that th...

Abstract

Disclosed are an autocrane hoisting manner and an autocrane rubber suspension system. A limit strip is disposed between a saddle and a balance beam of the autocrane rubber suspension system or between the balance beam and a frame of an autocrane. Hoisting of the autocrane is completed by the aid of the limit strip. The limit strip bears downward tensile force of unsprung mass and changes from loose state to a stretching state. When hoisting is completed, the limit strip changes from the stretching state to the loose state, and tires of the autocrane bear the downward tensile force of the unsprung mass. During hoisting, the limit strip is stretched to bear most tensile load so as to guarantee that the stretching of a rubber spring is in a reasonable range, stretching stress working conditions of the rubber spring are improved, and accordingly reliability of the rubber suspension system is improved.

Description

technical field [0001] The invention relates to a hoisting method of a truck crane and a rubber suspension system thereof, belonging to the field of engineering machinery. Background technique [0002] In China, rubber suspension is a new type of suspension system, which has excellent load-carrying capacity, and is easy to install, easy to assemble and disassemble, free from lubrication and maintenance, and more importantly, the self-weight of rubber suspension is higher than that of traditional leaf springs. The suspension is light, in line with the national policy of lightweight trucks, with good fuel economy, rubber suspension has begun to be widely used. However, when it is directly applied to a truck crane, due to the structure, operating conditions and manufacturing process of the truck crane, the following problems will occur: when the truck crane is hoisted, it will support the hydraulic support to let the tires of the car lift off the ground, so that the rubber The...
