Rear stable tail wagging mechanism of excavator

Abstract

The invention which belongs to the technical field of excavating apparatuses with excavating working faces for underground coal mine concretely relates to a rear stable tail wagging mechanism of an excavator to solve a problem that the fine tail adjustment of the excavator cannot be realized through rear stable mechanisms of present excavators. The rear stable tail wagging mechanism of the excavator, which comprises two rear support oil cylinders which are connected with the tail of an excavator body, is characterized in that: the piston rod end of each rear support oil cylinder is hinged to a rear support leg, the two rear support legs are respectively arranged on a left sliding shoe and a right sliding shoe, the left sliding shoe and the right sliding shoe are supported on a support base plate and can move relative to the support base plate, the support base plate is provided with a support seat which is hinged to the piston rod end of the wagging oil cylinder, and the wagging oil cylinder is hinged to the tail of the excavator body. Compared with the prior art, the rear stable tail wagging mechanism of the present invention has the advantages of flexible motion and good stability, so the problem that rear stable apparatuses of original excavators is solved, and the wagging velocity choice, and especially the turning choice of the tail of the excavator are improved.

Description

technical field [0001] The invention belongs to the technical field of tunneling equipment for tunneling working faces in coal mines, and in particular relates to a rear stabilizing tail swing mechanism of a tunneling machine. Background technique [0002] The existing roadheader rear stabilizing device includes a rear support leg and a rear support cylinder, the piston rod end of the rear support cylinder is hinged to the rear support leg, and the cylinder bottom end of the rear support cylinder is hinged to the machine tail. By extending the rear support cylinder, the rear support leg directly supported on the ground. This structure cannot realize the fine adjustment of the tail of the roadheader, and is limited by the structure, the supporting area is small, and the stability is poor. Contents of the invention [0003] In order to solve the problem that the existing roadheader rear stabilization mechanism cannot realize the fine adjustment of the roadheader tail, the p...
