Electric tensioning mechanism for tail turnabout drum of small-volume belt conveyor

Abstract

The utility model relates to an electric tensioning mechanism for a tail turnabout drum of a small-volume belt conveyor. The device is composed of a turnabout drum, a special-shaped bearing seat, a rack, a sliding shaft sleeve, a bronze washer, a motor reducer, a flat key, a lead screw, a nut, wheels, an adhesive tape and the like. The special-shaped bearing seat moves rightwards in the B direction, the rubber belt of the belt conveyor is tensioned, and the tensioning function is achieved; when the special-shaped bearing seat moves leftwards in the A direction, a rubber belt of the belt conveyor is loosened, and equipment maintenance can be carried out. Manual tensioning is replaced, and the automation degree is improved.

Description

Technical Field

[0001] The utility model relates to DTⅡ type belt conveyor equipment in coal washing and preparation plants and light industry fields. Background Art

[0002] DTⅡ belt conveyors in coal washing plants and light industry are often manually tensioned at the tail due to their small transport capacity and short transport distance. With the improvement of the overall automation level of the workshop, the maintenance and commissioning of DTⅡ belt conveyors need to improve efficiency, reduce labor intensity, and effectively improve production efficiency. Summary of the invention

[0003] The purpose of the utility model is to provide an electric tensioning mechanism for a tail redirecting roller of a small-capacity belt conveyor, which can be used to perform electric tensioning on a DTⅡ belt conveyor after maintenance, thus saving time and effort.

[0004] The technical scheme of the utility model is as follows: it is composed of a redirecting roller, a special-shaped bearing seat, a frame, a sliding sleeve, a bronze washer, a motor reducer, a flat key, a lead screw, a nut, a wheel and an adhesive tape; the redirecting roller, the wheel and the nut are assembled on the special-shaped bearing seat, and the sliding sleeve, the bronze washer, the motor reducer, the flat key and the lead screw are assembled on the frame; the lead screw and the nut cooperate to rotate relatively; the motor reducer drives the lead screw to rotate in the nut, and the nut drives the special-shaped bearing seat to move left or right, the wheel supports the special-shaped bearing seat and rolls along the ground with the traction of the driving lead screw, the redirecting roller is installed on the special-shaped bearing seat, and the adhesive tape of the belt conveyor is coiled on the redirecting roller; the special-shaped bearing seat moves rightward along the B direction, and the adhesive tape of the belt conveyor is tensioned to realize the tensioning function of the mechanism; the special-shaped bearing seat moves leftward along the A direction, and the adhesive tape of the belt conveyor is loosened, so that equipment maintenance can be carried out.

[0005] The beneficial effects of the utility model are:

[0006] The electric tensioning mechanism can improve efficiency, reduce labor intensity, and effectively improve production benefits during belt conveyor maintenance and commissioning; at the same time, it can provide moderate tension for the head drive roller to ensure good drive.

[0007] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 This is a schematic diagram of an electric tensioning mechanism for a tail redirecting roller of a small-capacity belt conveyor according to the utility model;

[0009] Figure 2 This is a working environment diagram of the electric tensioning mechanism of the tail redirecting roller of a small-capacity belt conveyor of the utility model;

[0010] In the figure: 1 redirecting roller, 2 special-shaped bearing seat, 3 frame, 4 sliding sleeve, 5 bronze washer, 6 motor reducer, 7 flat key, 8 lead screw, 9 nut, 10 wheel, 11 tape. DETAILED DESCRIPTION

[0011] like Figure 1 As shown, the redirection roller 1, wheel 10, nut 9 are assembled on the special-shaped bearing seat 2, and the sliding sleeve 4, bronze washer 5, motor reducer 6, flat key 7, and lead screw 8 are assembled on the frame 3; the lead screw 8 and nut 9 rotate relative to each other; the motor reducer 6 drives the lead screw 8 to rotate in the nut 9, and the nut 9 drives the special-shaped bearing seat 2 to move left or right, and the wheel 10 supports the special-shaped bearing seat 2 to roll along the ground. The redirection roller 1 is installed on the special-shaped bearing seat 2, and the belt 11 is coiled on the redirection roller 1 as shown. The special-shaped bearing seat 2 moves to the right along the B direction, and the belt 11 of the belt conveyor is tensioned, realizing the tensioning function of the mechanism; the special-shaped bearing seat 2 moves to the left along the A direction, and the belt 11 of the belt conveyor is loose, and the equipment maintenance can be carried out.
