Embodiment 1
[0025] The belt conveyor resettable two-stage deviation switch installation method of the present invention comprises the following steps:
[0026] a. The number of two-stage deviation switch 3 should be determined according to the length, type and layout of the belt conveyor. It should be set at the head, tail, convex arc, concave arc or middle of the belt conveyor. The mounting bracket 1 of the level deviation switch is welded and connected with the frame 5 of the belt conveyor, and the deviation switch and the support of the deviation switch are fixed with bolts; Vertical to the side plane of the conveyor belt of the belt conveyor, the two sides of the conveyor belt are located at 1 / 3 of the height of the vertical roller; the diameter of the idler roller 6 of the belt conveyor is 159mm.
[0027] see now figure 1 , figure 1 It is a schematic diagram of the location of the reset button according to the embodiment of the present invention. As shown in the figure, the reset ...

The invention provides an installation method of resettable two-grade deviation switches of a belt conveyor. The installation method is characterized by comprising the following steps: (a) arranging the two-grade deviation switches at the head part, the tail part, a convex arm section and a concave arc section of the belt conveyor or the middle position of the belt conveyor and arranging the double-stage deviation switches in pairs at the two sides of the belt conveyor; (b) preferably setting the distance from an upright roller of each deviation switch to a normal position of a conveying beltto be 50-100 mm; (c) setting two grades of angle for the two-grade deviation switches; and (d) additionally installing one reset button in a regular control circuit of each pair of two-grade deviationswitches, making a binding post (a) of each reset button be connected with an output end of a start button in series, and making a binding post (b) of each reset button be connected to an input end of a weight deviation signal control circuit in series. The installation method provided by the invention has the advantages that each two-grade deviation switch of the belt conveyor is simple in structure and convenient to manufacture; the problem that the belt conveyor cannot be started if the two-grade deviation switches are not reset when the belt conveyor stops working due to weight deviationcaused by uneven load of a belt or ultrahigh length of the belt is solved; and conditions are created for belt deviation correction work.
Description
technical field [0001] The invention relates to a method for installing a two-stage deviation switch for a belt conveyor, in particular to a method for installing a resettable two-stage deviation switch for a belt conveyor. Background technique [0002] The deviation switch is a product used to detect the deviation of the conveyor belt of the belt conveyor. It is a safety protection device that automatically alarms and shuts down when the conveyor belt deviates. The deviation switch has two levels of angles, of which the first level angles are: 10°, 12°, 20°. The secondary angles are: 30°, 35°, 45°. The two-stage deviation switch is widely used in various belt conveying equipment in the fields of metallurgy, coal, cement building materials, mining, electric power, ports, metallurgy, and chemical industry. Such as conventional belt conveyors, underground and cableway supported belt conveyors, ship loading and unloading systems, stacking / reclaiming conveyors, inclined and sh...
