Split type wheel excavator chassis

Abstract

The invention discloses a split type wheel excavator chassis. The split type wheel excavator chassis comprises a chassis main frame. The split type wheel excavator chassis is characterized in that connecting flanges integrally connected with the chassis main frame are arranged on the front end and the rear end of the chassis main frame respectively, and a plurality of threaded holes for connecting functional accessories are formed at the peripheries of the connecting flanges. The functional accessory connected to the front end of the chassis main frame is a shovel head support frame which is connected to the chassis main frame through a bolt; the functional accessory connected to the front end of the chassis main frame also can be a front shovel push system which is connected to the chassis main frame through a bolt. The functional accessory connected to the rear end of the chassis main frame is a rear support leg system which is connected to the chassis main frame through a support leg base plate arranged in the rear support leg system and a bolt. The split type wheel excavator chassis is applicable to operate under special working conditions, avoids wheel hanging, and simultaneously, satisfies the choice of a user on the functions of the wheel excavator.

Description

technical field [0001] The invention belongs to the field of wheeled excavators, in particular to the improvement of the chassis of the wheeled excavator. Background technique [0002] Although the crawler excavator has a large ground area, strong off-road capability, and good adaptability to the workplace, its own defects are also obvious, such as large investment, slow travel speed, and need to rely on carts for long-distance movement. For some small projects, the use of crawler excavators is not only costly, but also brings a lot of trouble. [0003] Compared with crawler excavators, wheeled excavators have many advantages, such as small investment, fast action speed, convenient operation, etc., so they are widely used. The main function of the currently used wheeled excavators is to carry out excavation operations through the bucket set on the boom. Carry out bulldozing operations when necessary; weld the inherent rear support leg system at the rear end of the chassis ...

AI Technical Summary

Problems solved by technology

However, because the front push blade system, the rear support leg system and the chassis are all welded, the three become a whole, which improves the rigidity of the whole machine, but this one-piece structure has many disadvantages

[0004] 1. Due to the integrated structure, when the operation area is uneven, the front push shovel system or the rear support leg system will touch the ground, causing the wheels to hang in the air, and the wheeled excavator cannot walk. Measures must be taken to get out of the predicament. Not only affects work efficiency, but also brings a lot of trouble

[0005] 2. Due to the one-sided pursuit of multi-function, this integrated structure will make the front push blade system and the rear support leg system always together with the main machine, and in some work areas, the front push blade system and the rear support leg system are not needed at all. This not only increases fuel consumption, but also affects operating efficiency

In addition, for owners who do not need the front push blade system and the rear support leg system, the installation of these two systems will inevitably increase the owner's purchase investment
