Problems solved by technology

[0003] When the existing excavator is working on the concrete ground, the excavation of the ground will cause the concrete on the ground to break, so that the track cannot completely touch the ground, and there will be obstacles in the process of moving forward, which will cause difficulty in moving. This process requires the machine itself to carry out a long process. Time adjustment, or manual adjustment, the process consumes a lot of time and delays work and time
[0004] The inventor found that the current crawler structure can only walk on flat ground, which is helpless when facing obstacles or devices with poor contact between the crawler and the ground, insufficient friction and difficulty in moving, and is still stretched in the face of complex road conditions such as obstacles of different heights.

Embodiment 1

[0050] In an exemplary embodiment of the present invention, reference is made to figure 1 As shown, an obstacle-surmounting crawler that can adapt to different heights includes a flat crawler 1 and a rotating crawler 2. The flat crawler 1 is rotated by the flat crawler driving wheel 3 to drive the crawler formed by the flat crawler shoe 5 to rotate, and the flat crawler driven wheel rotates. 4. Playing a supporting role, the flat track fixing shell 10 is provided with an extension arm on one side of the driving wheel to fix the flat track driving wheel, and the other side fixes the flat track driven wheel.

[0051] Among them, the minimum distance between the main wheel of the rotating crawler and the slave wheel of the rotating crawler, that is, the minimum distance between the center axes of the two, is greater than the distance between the center axis of the driven wheel of the flat track, that is, the center axis of the transmission shaft and the bottom side of the track on...

Embodiment 2

[0076] This embodiment provides an excavator, which adopts the obstacle-surmounting crawler of the first embodiment that can adapt to different heights;

[0077] Among them, refer to Figure 9 and Figure 10 As shown in the figure, the flat track is located on both sides of the main casing, and the two sides of the flat track are provided with rotating crawlers relative to the outer side of the main casing. Track driven wheels are connected and further connected to the rotating track by a drive shaft.

[0078] Among them, the main housing 47 is provided with a driving shaft bushing and a driven shaft bushing, the driving shaft 48 and the driven shaft 49 pass through the center of their respective bushings, and are connected with the driving wheel of the flat track, the center hole of the driven wheel of the flat track and the rotating track. The central hole of the main wheel is concentric; the driving shaft can be one, passing through the two flat crawler driving wheels on ...

Abstract

The invention discloses an obstacle-crossing crawler and an excavator that can adapt to different heights, solves the problem of poor obstacle-crossing ability of the current crawler structure in the prior art, and has the beneficial effect of being able to effectively overcome obstacles or move. The specific scheme is as follows The invention relates to an obstacle-crossing track capable of adapting to different heights, including a flat track and a rotating track. The flat track includes a flat track shoe supported by a flat track driving wheel and a flat track driven wheel, wherein the flat track driven wheel is the same as the rotating track main wheel. Shaft installation, the rotating track main wheel can drive the rotating track to rotate relative to the flat track, the rotating track includes a rotating track support plate, the rotating track supporting plate supports the rotating track main wheel and the rotating track follower wheel Multiple rotating track shoes are supported, and two adjacent rotating track shoes are connected by grooves; a telescopic mechanism is set between the rotating track main wheel and the rotating track follower wheel.

Description

technical field [0001] The invention relates to the field of excavators, in particular to an obstacle-crossing crawler and an excavator that can adapt to different heights. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] During the operation of the existing excavator, for the concrete ground, the excavation of the ground causes the ground concrete to break, so that the crawler track cannot fully contact the ground, and encounters obstacles in the process of moving forward, which makes it difficult to move. This process requires the machine itself to carry out long Time adjustment, or manual adjustment, the process consumes a lot of time, and the work is delayed. [0004] The inventor found that the current crawler structure can only walk on flat ground, which is helpless when facing obstacles or devices with poor contact between the crawl...
