Automatic locking device of head of coal rod machine

Abstract

The invention provides an automatic locking device of a head of a coal rod machine. The automatic locking device comprises a locking ring support and two semicircular locking rings. Two hydraulic cylinder connecting lugs are symmetrically connected to the outer sides of the two semicircular locking rings, a hydraulic cylinder connecting seat extends on the locking ring support, and one end of each hydraulic cylinder and a hydraulic rod at the other end of the hydraulic cylinder are respectively hinged to the corresponding connecting lug and the connecting seat. The automatic locking device of the head of the coal rod machine has the advantages that the head of the coal rod machine can be automatically detached and locked by the aid of the automatic locking device, the integral automatic locking device is advanced and reasonable in design parameters and control modes, and shortcomings of an old-fashioned locking device of a coal rod machine can be overcome.

Description

technical field [0001] The invention relates to an automatic locking device for the head of a coal rod machine. The utility model belongs to the technical field of coal rod machines, in particular to the technical field of locking heads of various types of coal rod machines. Background technique [0002] At present, in my country's industrial briquette production technology, extrusion coal rod machine (hereinafter referred to as coal rod machine) is widely used equipment. During the use of the coal rod machine, the machine head needs to be disassembled frequently for maintenance, overhaul and replacement of parts. However, at present, the locking devices of the coal rod machine heads used in the chemical briquette industry are all manually operated, and the locking methods have the following disadvantages: [0003] 1. The locking of the head of the coal rod machine is manual operation, and the degree of automation is low. [0004] 2. The locking ring of the coal rod machi...
