Working mechanism for underground coal mine ultra-heavy shovel plate type shield hauler

Abstract

The invention belongs to the technical field of underground coal mine auxiliary transportation, and particularly relates to a working mechanism for an underground coal mine ultra-heavy shovel plate type shield hauler. The working mechanism solves the problems that an existing shovel plate type shield hauler is weak in shoveling and lifting, a shovel plate cannot be lifted to a certain distance away from the ground, and normal transportation cannot be achieved through the shield hauler. The working mechanism is characterized in that a shovel fork and a shovel fork seat are fixed through a hingepin set I, one end of a connecting rod is connected with the fork seat through a hinge pin set II, the other end of the connecting rod is connected with one end of a rocker arm through a hinge pin set III, the other end of the rocker arm is connected with a piston rod lug of a tipping oil cylinder set through a hinge pin set V, the middle of the rocker arm is connected with a large arm through ahinge pin set IV, a cylinder barrel lug of the tipping oil cylinder set is connected with a front machine frame through a hinge pin group VII, a cylinder barrel lug of a lifting oil cylinder set cylinder lug is connected with the front machine frame through a hinge pin set X, and a lower hinge hole and an upper hinge hole are connected with a rear machine frame through a pin shaft. According to the working mechanism for the underground coal mine ultra-heavy shovel plate type shield hauler, stable and reliable and strong force output can be kept in the overload operation process of the hauler.

Description

technical field [0001] The invention belongs to the technical field of underground auxiliary transportation in coal mines, in particular to a working mechanism for an ultra-heavy shovel-type support transport vehicle in underground coal mines. Background technique [0002] At present, with the emergence of full-height and heavy-duty working faces with super-large mining heights in coal mines, the hydraulic support has also increased correspondingly, with a total weight of 80 tons and above, and the weight of other auxiliary equipment has also broken the record of the original equipment. The maximum tonnage of the heavy-duty shovel-type support truck can only reach 55 tons, and the ultra-heavy-duty shovel-type support truck (80 tons and above) is limited by the size of the coal mine underground roadway, and the vehicle’s overall size cannot be ideally expanded. Therefore, the lifting of the vehicle’s working mechanism The cylinder diameters of the lifting oil cylinder and the...

Problems solved by technology

[0003] In order to solve the problem that the shovel-type support carrier transports the super-heavy hydraulic support or other equipment of 80 tons or more in the coal mine, the shovel is weak, the shovel cannot be raised to a certain height from the ground, and the vehicle cannot be transported normally.
