Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0042] Such as figure 2 , image 3 and Figure 4 As shown, a quick-change implement bracket for an engineering vehicle includes a rotating bracket 1 , a lower platform 3 , an intermediate platform 5 and an upper platform 10 . Among them, the rotating bracket 1 and the lower platform 3 are fixedly connected by a bolt group; the lower platform 3 and the middle platform 5 are slidably connected by slide rails, and are locked by two sets of first locking pins 2 and O-shaped cards 11 in the transportation state (stationary state). The two are fixed to avoid relative sliding; there are four pre-compressed anti-loosening springs 7 between the middle platform 5 and the upper platform 10, and the low...

Abstract

The invention discloses a quick-change machine tool bracket for an engineering vehicle. The quick-change machine tool bracket comprises a rotation bracket body, a lower platform, a middle platform andan upper platform. The lower platform is fixedly connected to a rotation bracket body capable of horizontally rotating. The lower platform is slidingly connected with the middle platform through a horizontal slide rail. Multiple pre-compression springs are arranged between the middle platform and the upper platform. The lower ends of the springs are fixed through lower positioning pins, and the upper ends of the springs are fixed through upper positioning pins. The upper positioning pins and the lower positioning pins are in a retractable matched state so that the upper platform and the middle platform can oppositely move in the vertical direction. According to the quick-change machine tool bracket for the engineering vehicle, the aim that the machine tool bracket is fixedly connected with the engineering vehicle is achieved, so that a machine tool rotates at the degrees of freedom in the up-down, front-rear and vertical directions in the replacement process, the platform bracket cancarry the machine tool to adjust the position of the machine tool with quick-change rotation, the situation that the machine tool is pressed by an arm rest in the quick-change movement process is avoided, the damage to the machine tool is lowered, the time of quickly replacing the machine tool is greatly shortened, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a quick-change implement bracket for an engineering vehicle, which belongs to the technical field of engineering machinery. Background technique [0002] With the continuous development of the construction machinery industry, construction machinery operation tools are increasingly being highly valued, and "one machine with multiple functions" has also become the development trend of construction machinery. In order to adapt to the different environments of emergency rescue, construction machinery such as excavators and fire trucks have begun to develop in a multi-functional direction in recent years. Many construction vehicles are equipped with a variety of working tools, and quick connectors (quick change for short) are used between the tools and the working arm. Connection, in the process of tool switching, there is a wide range of quick-change compression tools. In order to realize the rapid replacement of engineering vehicl...
