Embodiment Construction

[0019] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0020] The specific embodiment of the present invention is like this: as Figure 1-2 As shown, a limit mechanism for adjusting the width of the vehicle frame includes a main vehicle frame 1 and two crawler frames 2 on the left and right. The inner sides of the two crawler frames 2 are provided with two slide rails inserted into the main frame 1 and set. 3. A hydraulic cylinder mechanism 4 connected with two crawler frames 2 is slid inside the main frame 1 . In the limit mechanism of the width-adjusting frame, the telescopic push rod of the hydraulic cylinder mechanism 4 can adjust the distance between the two crawler frames 2, and the hydraulic cylinder mechanism 4 can slide relative to the main frame 1. Under the gui...

Abstract

The limiting mechanism comprises a limiting mechanism of a width-adjustable frame. The limiting mechanism comprises a main frame, a left crawler belt frame and a right crawler belt frame, wherein inner sides of the two crawler belt frames are each provided with two sliding rails inserted into the main frame, and a hydraulic cylinder mechanism connected with the two crawler belt frames is arrangedin the main frame in a sliding mode. The limiting mechanism of the width-adjustable frame belongs to the technical field of excavators, is ingenious in structure and convenient in hydraulic adjustment, can realize width adjustment of the frame only by one hydraulic cylinder mechanism and simple connection, and is simple in structure and lower in cost, the left crawler frame and the right crawler frame slide through matching of sliding rails and sliding grooves, so telescopic stability and flexibility of the frame are higher.

Description

technical field [0001] The invention relates to the technical field of excavators, more specifically, it relates to a limit mechanism for adjusting the width of the vehicle frame. Background technique [0002] Among the existing excavators, the telescopic frame is widely used in miniature excavators, but the width adjustment mechanism is relatively complicated, usually driven by multiple oil cylinders, the cost is high, the adjusted width is difficult to achieve the ideal state, and the operation is inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to solve some of the above-mentioned deficiencies in the prior art, and the purpose of the present invention is to provide a width-adjustable vehicle frame limit mechanism that is convenient for width adjustment. [0004] In order to achieve the above purpose, the present invention provides a limit mechanism for adjusting the width of the vehicle frame, which includes...
