Problems solved by technology

This patent is only for the conversion of the two walking modes of the crawler and the pontoon. However, an external transport vehicle is still required for consignment when transferring to flat ground, which not only increases the cost of use, but also causes vibrations in other parts of the excavator during the consignment process. mechanical loss

Embodiment 1

[0026] Such as Figure 1-6 shown.

[0027] A crawler wheel excavator, comprising a fuselage 1, an excavating arm 2, an excavating hopper 3, and a running gear; the running gear includes a chassis 4, crawlers 5, lifting front wheel frames 6, and lifting rear wheel frames 7;

[0028] Two first oil cylinder telescopic arms 8 are arranged on the front end of the chassis 4, and the other end of the first oil cylinder telescopic arm 8 is connected to the front rectangular tube 10 of the vehicle frame through the rotating shaft 9, and the front rectangular tube 10 of the vehicle frame is connected to each other. One end is connected to the bottom of the chassis 4 through a rotating shaft 11, and a locking shaft 12 is provided on one side of the other end of the front rectangular tube 10 of the vehicle frame; the lifting front wheel frame 6 includes road wheels 6-1, two rectangular tubes 6- 2 and a locking plate 6-3, the two rectangular tubes 6-2 are respectively inserted into the fr...

Embodiment 2

[0031] A working method of a crawler wheel excavator as described in embodiment 1, comprising the following working steps:

[0032] Such as figure 1 shown. When the excavator is crawler-type walking, the crawler-wheeled excavator passes through the contraction of the first oil cylinder telescopic arm 8 and the contraction of the second oil cylinder telescopic arm 8-1: respectively lift the lifting front wheel frame 6 and the chassis set at the front end of the chassis. The lifting rear wheel frame 7 arranged at the rear end realizes the lifting of the walking wheels 6-1, 7-1, and the grounding of the crawler belt 5;

[0033] Such as Figure 6 shown. When the excavator walks in a wheeled manner, the crawler wheeled excavator will drop the lifting front wheel frame 6 set at the front end of the chassis through the extension of the first oil cylinder telescopic arm 8 and the extension of the second oil cylinder telescopic arm 8-1. , the lifting rear wheel frame 7 that chassis...

Abstract

The invention relates to a track-wheel type excavator which comprises an excavator body, an excavating arm, an excavating bucket and a traveling mechanism with oil cylinder telescopic arms, wherein the traveling mechanism comprises a chassis, tracks, a lifting front wheel frame and a lifting rear wheel frame. The invention further provides a working method of the track-wheel type excavator. Track type traveling and wheel type traveling can realize hydraulic oil control by the aid of the oil cylinder telescopic arms, control is flexible and changeable, and the track-wheel type excavator is adaptive to alternation in various road conditions and high alternation rate. The track-wheel type excavator can change the traveling mode of a track type excavator according to the road conditions and is adaptive to various paths, so that towing cost is saved greatly. The track-wheel type excavator achieves free switching of the track type traveling and the wheel type traveling by means of mechanical transformation and transmission change on lifting of front and rear wheels on an excavator site, and accordingly the track-wheel type excavator is flexible to operate and convenient for site change.

Description

technical field [0001] The invention relates to a crawler wheel excavator and a working method thereof, belonging to the technical field of excavating heavy machinery. Background technique [0002] Common excavator structures include: power unit, working device, slewing mechanism, steering mechanism, transmission mechanism, walking mechanism and auxiliary facilities. The excavators are divided into crawler excavators and wheeled excavators according to the walking mode, and excavators with different walking modes are selected according to the type of site where the task is performed: when the working road surface is flat, the wheeled excavator is mostly used, which has the characteristics of walking It is convenient and does not need an external consignment locomotive to consign it; when the working road is muddy, crawler excavators are often used for work, but its disadvantage is that walking on asphalt and flat ground will cause great damage to the ground and cause strain ...
