Embodiment Construction

[0012] Such as figure 1 with figure 2 As shown, the telescopic excavating arm hydraulic pipeline follow-up mechanism of the present invention includes a main arm 5, and a telescopic arm 2 is arranged inside the main arm 5. formula fit. A bucket 1 is arranged at the front end of the telescopic arm 2 . A support 20 is fixed in the middle of the inner cavity of the telescopic arm 2, and a telescopic oil cylinder 13 is arranged between the support and the rear end of the main arm 5, and the two ends of the telescopic oil cylinder 13 are respectively hinged on the support 20 and the rear end of the main arm 5. The telescoping arm 2 before the support 20 is provided with a bucket oil cylinder 4, one end of the bucket oil cylinder is hinged with the support 20, and the other end is connected with the bucket 1 through a rocker linkage mechanism. A jaw oil cylinder 3 is arranged under the front end of the telescopic arm 2, a transition joint 18 is fixed in the middle of the lower s...

Abstract

The invention relates to a telescopic follow-up mechanism for a telescopic digging arm hydraulic pipeline, comprising a main arm, wherein the main arm is equipped with a telescopic arm; the telescopic arm is equipped with a support; a telescopic oil cylinder is arranged between the support and the rear end of the main arm; the telescopic arm in the front of the support is internally equipped witha bucket oil cylinder, and two ends of the bucket oil cylinder are respectively hinged with the support and a bucket; a clamping jaw oil cylinder is arranged at the lower of the front end of the telescopic arm, and a transit joint is arranged in the middle of the lower side wall of the main arm; a large drift diameter hose, a first hose and a third hose are arranged between the transit joint and the bucket oil cylinder; hydraulic oil transmitted by the first hose and the third hose is gathered and then converged in the large drift diameter hose; and a second hose is arranged between the transit joint and the clamping jaw oil cylinder, wherein the drift diameter of the second hose is more than the drift diameter of the large-drift diameter hose; and the first hose, the second hose and the third hose are parallel connected on a spring steel band through a hoop so that the first hose, the second hose and the third hose move with the spring steel band. The invention can improve working performance and working capability of the digging arm, avoid disturbance situation of the hoses, and prolong service life of the hoses.

Description

technical field [0001] The invention relates to an excavator. Specifically, it is the hydraulic pipeline follow-up mechanism of the telescopic excavating arm on the hydraulic excavator. Background technique [0002] It is known in the field of excavator production and application that the telescopic excavating arm hydraulic pipeline follow-up mechanism contains a main arm, and a telescopic arm is arranged in the main arm, and the main arm and the telescopic arm are telescopically matched by means of rollers. There is a bucket at the front end of the telescopic arm. A support is fixed in the middle of the inner cavity of the telescopic arm, and a telescopic oil cylinder is arranged between the support and the rear end of the main arm, and the two ends of the telescopic oil cylinder are respectively hinged on the support and the rear end of the main arm. There is a bucket oil cylinder in the telescopic arm before the support, and the two ends of the bucket oil cylinder are h...
