Abstract

PROBLEM TO BE SOLVED: To smooth movement of a belt by sliding a belt on a flat band-like sheet to be drawn in, connecting both ends of the belt to each other to form an endless belt, and then removing a clamper to pull out the flat band-like sheet from between the belt and the carrier side trough. SOLUTION: A belt is slid on a flat band-like sheet 10 to be moved and wrapped round the other pulley side. Further, the belt is moved on a flat band- like sheet provided similarly to a carrier side trough 5a on a return side trough, and then both ends of the belt are connected to each other to form an endless belt. After that, a clamper is removed to pull out the flat band-like sheet 10 from between a carrier side belt 3a and the carrier side trough 5a. Thus, on the upper surface of the carrier side trough 5a, the flat band-like sheet 10 with a low coefficient of friction like Teflon or the like is disposed at a space, so that when the belt is moved, the frictional resistance between the belt and the upper surface of the carrier side trough 5a can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a belt on a belt conveyor for transporting bulk materials such as coal.
More particularly, the present invention relates to a belt mounting method for an air-floating belt conveyor that supports a belt with an air film.

[0002]

2. Description of the Related Art An air duct provided on a lower surface of a carrier side trough, wherein a carrier side of a conveyor belt which moves by winding pulleys provided at both ends is supported by a carrier side trough having a downwardly convex curved surface. There is known an air-floating belt conveyor that blows air through a large number of pores formed along the center line of a trough to form an air film between the upper surface of the trough and the lower surface of the belt (see, for example, Japanese Patent Application Laid-Open No. H11-157572). Japanese Unexamined Patent Publication No. Hei 8-244933.

The length of an air-floating belt conveyor currently used is often about 70 m to 100 m. The belt mounting method of such an air-floating belt conveyor is such that after installing the main body of the belt conveyor, the belt is placed on one pulley, and one end of the belt is fixed to a wire such as a winch provided on the other pulley side, While pulling the upper surface of the steel sheet trough with a winch, the sheet is wound around the other pulley to connect both ends of the belt to form an endless belt.

[0004]

However, in recent years,
Long belt conveyors with a length of 100 m or more are being used.However, when the belt is too long, when the belt is installed, air cannot be blown out from the air duct to float the belt, as during belt conveyor operation. In addition, the frictional resistance between the belt and the upper surface of the trough is large, making it difficult to pull and move the belt, which takes time and troubles the installation efficiency of the belt conveyor. There is also a problem that a large winch or the like for pulling a long belt is required.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and when the belt is moved by pulling, the belt is easily moved to reduce the time and effort required for installation. To improve work efficiency,
It is another object of the present invention to provide a method for mounting an air-floating belt conveyor that can reduce the size of a winch or the like.

[0006]

According to the present invention, the carrier side of an endless conveyor belt that is moved by winding pulleys provided on both sides is provided by a carrier-side trough having a downwardly convex curved surface. Supporting, air is blown out from the air duct provided on the lower surface of the carrier side trough through a number of holes drilled along the center line of the trough to form an air film between the upper surface of the trough and the lower surface of the belt A belt mounting method for an air levitation type belt conveyor, in which a flat belt-like sheet having a low coefficient of friction such as Teflon or the like is arranged on the upper surface of the carrier side trough in a longitudinal direction of the carrier side trough so as to be orthogonal to the carrier side trough prior to the belt mounting. At the required intervals, fix both ends of the belt with a clamper, and then slide the belt over the flat sheet. An endless belt is formed by connecting both ends of the belt, and then the clamper is removed to remove a flat belt-like sheet from between the belt and the carrier-side trough. A method is provided.

Next, the operation of the present invention will be described. Since a flat belt-like sheet such as Teflon having a low friction coefficient is disposed on the upper surface of the carrier-side trough at a required interval, frictional resistance between the belt and the upper surface of the trough can be reduced when the belt is moved. Therefore, the belt can be moved smoothly. Further, since the belt moves smoothly, the winch and the like can be reduced in size. After attaching the belt, the flat belt-like sheet can be easily removed.
