Installation and construction method for corrugated large-inclination flange belt conveyor

Abstract

The invention discloses an installation and construction method for a corrugated large-inclination flange belt conveyor, which comprises the following steps of: 1, finding out a centre line of the complete machine and a cross line of centre lines of a head pulley and a tail pulley according to a working drawing; 2, installing a head frame, a driving device, a convex arc-shaped middle frame and a convex arc-shaped pinch roller according to a centre line of a complete-machine frame and a cross line of the head pulley; 3, laying an annular flange conveyer belt 7; 4, taking the centre lines of the head frame and a tail frame as references, installing a middle frame support, a middle frame and the tail frame in turn from the machine head; 5, installing a return roller without installing other carrier rollers or rollers, and loosening a chain to make the annular flange conveyer belt fall onto the frame; 6, installing an upper flat carrier roller and a tension roller, and adjusting a tension device to the loosest position in the process of installing the tension roller; 7, installing a concave arc-shaped pinch roller, a concave arc-shaped carrier roller, a convex arc-shaped carrier roller and upper and lower blocking rollers; and 8, installing a sweeper and other accessories and getting ready for debugging.

Description

technical field [0001] The invention relates to the field of belt conveyors, in particular to an installation and construction method for sidewall belt conveyors. Background technique [0002] The corrugated sidewall conveyor is a device for continuous conveying of bulk materials. Because it uses a belt with corrugated sidewalls and transverse partitions, it is especially suitable for large-inclination conveying. It has the advantages of easy angle change, small footprint, low energy consumption, low noise, large conveying capacity, smooth belt operation, long service life, many optional types, and low overall cost. It is widely used in coal, grain, building materials, Chemical industry, hydropower and metallurgical industry and other departments. [0003] Belt laying with wavy sidewall and large inclination angle is one of the key processes of the whole installation project. For ordinary belt laying, the whole roll of belt is usually placed at the machine head, and a round...

Problems solved by technology

[0005] 1. The installation sequence of the equipment, improper installation sequence will cause rework;

[0006] 2. The center line of the upper and lower bends must coincide with the center line of the whole machine. Neglecting this point will cause serious deviation of the belt and make it difficult to adjust;

[0007] 3. The laying and fixing of corrugated sidewall belts, because this kind of belt is ring-shaped, and has sidewalls and transverse partitions, it is not easy to transport like ordinary belts in rolls, and it is generally folded into rectangles to arrive, which makes laying difficult

However, the structure of the wavy sidewall and large inclination angle is different from ordinary belts. The laying of the wavy sidewall and large inclination angle belt is one of the key processes of the entire installation project. Ordinary belt laying usually uses the whole roll of belt to be placed at the machine head, and a round tube is inserted into the center of the belt. , and then hoist it with an inverted chain, and lay it from high to low as the belt rolls, saving time and effort; but the same method cannot be used for the belt with a large inclination angle on the wavy sidewall. It is rectangular, long and high in shape, and does not have the overall The rolling characteristics of the roll belt, coupled with the ribs and partitions on the surface of the corrugated sidewall and large-angle belt, are not conducive to sliding. Belt laying quality and work efficiency, an important guarantee for shortening the construction period
