Embodiment Construction

[0027] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0028] The present invention is mainly made up of working mechanism, frame, left and right walking mechanism, hydraulic system, electric system etc. (such as figure 1 As shown), it is driven by hydraulic pressure and has the functions of lifting, swinging, and self-propelled, and can realize the horizontal, vertical, and steering movements of the dragged object.

[0029] The working mechanism is composed of a telescopic cylinder, a lifting body and a swing cylinder that can be connected with a hydraulic support (such as figure 2 As shown), the telescopic cylinder 10 is connected with the lifting body 13 through the pin shaft 12, and forms a pivot point. The two ends of the swing cylinder 11 are respectively connected with the telescopic cylinder 10 and the lifting body 13. The left and right swing of the telescopic cylinder.

Abstract

The invention discloses a traction machine for removing a coal-mine hydraulic support, which belongs to the technical field of underground auxiliary transportation equipment, and solves the problem that in the process of removing existing hydraulic supports by a winch, the traction is low in efficiency and poor in safety. The invention comprises a frame, an operating mechanism and a traveling mechanism, wherein the operating mechanism comprises a retracting cylinder, a lifting body and rotary actuators; one end of the lifting body is connected with the frame and then upper and lower rotating hinge points are formed, the other end of the lifting body is connected with the retracting cylinder and then left and right rotating hinge points are formed; and the two ends of each rotary actuator are respectively connected with the retracting cylinder and the lifting body, two rotary actuators are symmetrically arranged relative to the retracting cylinder, and the bottom of the lifting body isconnected with a lifting cylinder. The invention has the advantages of realizing the mechanized operation, improving the efficiency and safety of hydraulic-support removing, solving the technical problems of mechanized operation on hydraulic-support disassembling in the process of removing the hydraulic supports on a combined mining face, and forming a new hydraulic support removing process.

Description

technical field [0001] The invention belongs to the technical field of underground auxiliary transportation equipment in coal mines, and in particular relates to a coal mine hydraulic support retraction tractor, which is a traction device used for support removal during the retraction process of a hydraulic support in an underground fully mechanized mining face. Background technique [0002] In the process of withdrawing the hydraulic support of the traditional fully mechanized working face, the lifting hoist is used to cooperate with the winch to disassemble, and the mine car and other equipment are relay-transported. The return efficiency of the working face support is very low, and it usually takes 4 to 6 weeks. Only one working face can be withdrawn, and the mechanization degree of the whole process is low, the labor intensity of workers is high, and the safety is poor. In recent years, the hydraulic support retraction process of multi-channel support trucks has been ado...
