Sling cart for fully-mechanized mining working surface push conveyer

Abstract

The invention discloses a sling cart of a push conveyer in a fully mechanized face. The sling cart comprises a cart frame and wheels, wherein, the cart frame is provided with a transverse girder, a longitudinal girder and two perpendicular frame hydraulic cylinders. Jointed shafts are arranged between the cantilevers at the upper ends of the frame hydraulic cylinders and the longitudinal girder; the upper parts of the jointed shafts are hinged with suspension arms; the suspension arms and the lower parts of the hinged shafts have suspension arm hydraulic cylinders; the external ends of the suspension arms are connected with supporting chain hydraulic cylinders; the external ends of the cylinder rods of the hydraulic cylinders are connected with the supporting chains; the external ends of the supporting chains are provided with crown blocks; the supporting chains move round the crown blocks; the external ends of the suspension arms are connected with the supporting chains; the lower ends of the supporting chains are connected with middle groove clamp fasteners which have I-shaped frames; one ends of the I-shaped frames are provided with fixed hooks with outward hooks and the other ends of the I-shaped frames are provided with hinged hooks with outward hooks; and hinged hook hydraulic cylinders are arranged between the upper ends of the hinged hooks and the I-shaped frames. The invention can unload the middle groove from a flat-bottom cart in a way of hoisting, convey the middle groove into a loading position and assemble the middle groove into a coal-conveying groove, thereby the labor intensity of the loading work of the push conveyer in the fully mechanized face is less, loading speed is fast, work efficiency is high and the security of the loading work is good.

Description

technical field [0001] The invention relates to an installation device for a complete set of fully mechanized mining equipment in a coal mine, in particular to a hoisting vehicle for a central trough of a bendable scraper conveyor coal delivery trough on a fully mechanized mining face. Background technique [0002] The flexible scraper conveyor (hereinafter referred to as the scraper conveyor, the same below) is an important equipment of the coal mine fully mechanized mining complete set of equipment. The scraper conveyor is located at the front and bottom of the fully mechanized mining face. It is not only used to transport the coal mined by the shearer from the working face in a timely manner, but also serves as the running guide rail of the shearer and the fulcrum of the displaced hydraulic support. The scraper conveyor has a front conveyor and a rear conveyor. Between the front and rear conveyors is a coal delivery trough connected by multiple middle slots in sequence. T...

AI Technical Summary

Problems solved by technology

In the prior art, there is no special equipment for the installation of the coal delivery chute. During the installation process of the coal delivery chute, the unloading, handling and assembly of the middle chute are completed by manpower unloading, winch dragging, and manual assembly.

In this way, the labor intensity of installing the coal chute is high, the installation speed is slow, the work efficiency is low, and there are many potential safety hazards
