Embodiment Construction

[0015] The following is a detailed description of the present invention in conjunction with the accompanying drawings in order to gain a better understanding:

[0016] The middle spiral tensioning device of the reversible belt conveyor includes a tensioning bracket 1 and a screw 3. The upper end of the tensioning bracket 1 is fixed on the middle bracket 6 with fasteners, and the bottom foot plate 11 is directly welded to the embedded part. Both the left and right ends are equipped with a reversing roller 5 by means of fasteners; there is a fixed guide rail 4 in the middle of the tension bracket 1; one end of the screw 3 is connected with a nut 2 welded on the tension bracket 1 It is connected by a thread pair, and the other end is fixed and can only move up and down along the guide rail 4 on the tensioning bracket 1 and is connected to the seated bearing 9 by means of a retaining ring 7 and a screw 8; Tightening roller 10; each of the tensioning rollers 10 and reversing rollers 5...

Abstract

The invention relates to a middle screw take-up device of a reversible belt conveyor. The middle screw take-up device comprises a support which is fixedly arranged and a threaded rod of which one end is fixed to the support. A guide rail which is fixedly installed is arranged in the middle of the support. Turnabout drums are arranged on the two sides of the support respectively. Lifting devices carrying out lifting movement vertically along the guide rail are arranged in the path of the threaded rod. Each lifting device is provided with a take-up drum. The take-up drums correspond to the turnabout drums, and the take-up drums and the turnabout drums are provided with conveyor belts in a penetrating mode. The middle screw take-up device has the advantages of being simple and compact in structure, capable of saving space and time, good in flexibility, convenient to mount, dismount and operate, low in basic requirement, safe, reliable, capable of meeting the requirement for product seriation easily, and capable of making the conveyor belts generate enough tension, limiting the sag of the conveyor belts among all carrier rollers, guaranteeing enough friction between the conveyor belts and transmission drums so as to prevent the conveyor belts from slipping, and guaranteeing normal operation of the reversible belt conveyor.

Description

Technical field: [0001] The invention relates to the field of belt conveyors, in particular to an intermediate spiral tensioning device of a reversible belt conveyor. technical background: [0002] Belt conveyors are widely used in metallurgy, coal, electric power, building materials, chemical industry, transportation, light industry and other industries. The tensioning device is one of the important parts of the belt conveyor. Its main function is to make the conveyor belt have enough tension to ensure that there is enough friction between the conveyor belt and the drive roller so that the conveyor belt does not slip, and to limit the conveyor belt in each The sag between the rollers makes the belt conveyor run normally. For some reversible belt conveyors, because both the head and the tail need to be unloaded, the space is limited, and the ordinary tensioning method is inconvenient to use. The intermediate tensioning device is usually used, but the existing intermediate...
