Problems solved by technology

[0004] 1) Axle suspension, power loss
The chassis of super-large-tonnage cranes is long and the drive shafts are arranged on the front axles of the vehicle. On mountainous roads with steep up and down slopes and small leading slopes, some drive shafts are prone to hang in the air, and the remaining drive shafts provide insufficient power, which seriously affects The use performance of the whole machine on mountain roads reduces the transition efficiency
When the suspension of the axle is serious, the load of some axles exceeds the allowable load limit, which will cause damage to the relevant components on the crane chassis, causing a lot of inconvenience to the user and corresponding economic losses
[0005] 2) Single purpose, waste of resources
The chassis of the super-large tonnage crane adopts a rigid structure, which is connected with the crane operation module before leaving the factory, and it is difficult to disassemble and assemble at the user's place
The only function of its chassis is the transportation of the crane operation module, which is highly specific and cannot be used for other cargo transportation and traction purposes.
When the crane is hoisting, the chassis part is idle, which is a waste of resources for the user
[0006] 3) Troublesome disassembly and maintenance
The chassis of a super-large tonnage crane is an integral structure. Once a part is damaged, the whole crane cannot be moved. The chassis is compactly arranged, limited by space, difficult to maintain, and takes a long time to repair, which brings serious economic losses to users.
[0007] 4) Heavy load transition, lack of power
Compared with the steep and undulating mountainous roads, the configured power still cannot meet the user's heavy-duty transition needs, and often needs to be dragged with the help of a loader, which has a certain degree of safety and increases the user's use cost.

Abstract

The invention discloses a modular flexible chassis, application thereof and a crane thereof, and belongs to the field of crane equipment. The chassis consists of multiple modules with different functions; all the modules adopt different combination and connection modes to realize flexibility and modularization of a vehicle body; the assembled chassis is high in ground self-adaptability; the chassis comprises a driving control driving module positioned at an advancing end, support bearing modules connected with the driving control driving module, a crane operation module arranged between the support bearing modules, and a driven driving module positioned at a tail end; the support bearing modules include a front support bearing module and a back support bearing module; the crane operation module is positioned between the front and back support bearing modules; the driving control driving module is connected with the front support bearing module; and the driven driving module is connected with the back support bearing module. Compared with a traditional structure, the modular flexible chassis has such multiple functions as high ground self-adaptability, multiple purposes, convenience to maintain and high power.

Description

technical field [0001] The invention relates to a crane chassis, in particular to a modular flexible chassis, its application and a crane, belonging to the field of crane equipment. Background technique [0002] At present, the ultra-large tonnage cranes in the industry generally use a rigid integral mechanical four-axis drive chassis, such as figure 1 Middle 1, 2, 4, 5 axis drive, overall frame rigidity. The oil-air suspension system is adopted, and the overall axle is divided into two groups ( figure 1 As shown, it is divided into two groups of 1-5 and 6-7), each group of axles adapts to the ups and downs of the road surface through the stroke fluctuation of the suspension cylinder, the stroke of the suspension cylinder is limited, and the adaptability to the road is not high. There are also some super-large-tonnage cranes that add a hydraulic drive shaft to improve the climbing ability. These drive shafts are often affected by mechanisms, transmission ratios, etc., and ...
