Telescopic tail of belt conveyer

Abstract

The invention discloses a telescopic tail of a belt conveyer, belonging to mining equipment. A tailstock connected with a stand of the belt conveyer comprises slide rods 3, slide sleeves 5, lifting oil cylinders 4 and telescopic oil cylinders 7, wherein the supporting legs 1 are fixed to the end parts of the two slide rods 1, and the slide rods 3 are connected with a longitudinal beam 14 at the tail end of the stand through supporting pipe seats 13; both ends of the slide rods 13 are connected through a slide rod connecting beam 17; the slide sleeves 5 are slidably matched and sleeved on the slide rods, and both ends of the slide sleeves 5 are connected through a slide sleeve connecting beam 18; four lifting oil cylinders 4 are fixed on the slide sleeves 5; the two telescopic oil cylinders 7 are fixed on the lower sides of the slide sleeves 5; the end part of a piston rod is connected with the supporting leg 1 fixed at the outer end of the slide rods 3 through a connecting rod 2; a movable slot-shaped carrier roller 10 is arranged on a carrier roller bracket 20, and an outward flanging is manufactured at the upper end of the carrier roller bracket 20; the flanging is provided witha double-brake roller wheel 11, and the double-brake roller wheel 11 is erected on the slide rods 3 and can move left and right; and a fixed slot-shaped carrier roller 12 is arranged on the slide rods 3 through a carrier roller beam 21.

Description

technical field [0001] The invention relates to a mine equipment, in particular to a tail of a coal mine underground belt conveyor whose end length can be stretched and changed. Background technique [0002] The belt conveyor is the coal conveying equipment used on the coal mining face of the coal mine. It transports the coal cut by the coal cutter to the shaft, and then sends it to the ground through the shaft lifting device. The coal cut by the coal cutter is sent to the tail of the belt conveyor through the scraper machine. Since the height of the belt conveyor is higher than that of the scraper machine, the scraper machine cannot transport the coal cut by the coal cutter to the belt conveyor. on board. At present, most coal mines use one or more transfer scraper machines for intermediate transfer, which has low production efficiency and large investment in equipment. The patent (CN201033693Y) of "Ultra-low Mobile Tail of Belt Conveyor" applied by the applicant in 2007 ...

Problems solved by technology

The coal cut by the coal cutter is sent to the tail of the belt conveyor through the scraper machine. Since the height of the belt conveyor is higher than that of the scraper machine, the scraper machine cannot transport the coal cut by the coal cutter to the belt conveyor. on board

At present, most coal mines use one or more transfer scraper machines for intermediate transfer, which leads to low production efficiency and large investment in equipment

The patent (CN201033693Y) of "Ultra-low Mobile Tail of Belt Conveyor" applied by the applicant in 2007 effectively solved the above-mentioned technical problems, but it also has deficiencies. When the coal mining face advances 0.8-1.2 meters, The mobile tail must be replaced once to adjust the longitudinal beam, and it needs to be adjusted several times in one work shift, which is troublesome and affects work efficiency. In addition, the mobile tail is dragged on the ground by two bottom plates. Due to the unevenness of the underground ground, the height of the tail is difficult control
