Abstract

The utility model discloses an anti-deviation tensioning device for a belt conveyor. The anti-deviation tensioning device for a belt conveyor includes a tensioning frame on which a bearing seat of a rotary frame is fixed. The rotary frame There are bearings in the bearing seat, and the lower end of the slewing frame is inserted into the bearing. The slewing frame is provided with a tensioning roller, and the two ends of the tensioning roller are installed in the roller bearing seat through bearings. Vertical rollers are arranged on the same side; two pulleys are also arranged horizontally on the tensioning vehicle frame. The utility model can not only provide the necessary tension force for the belt conveyor, ensure the tension required for the normal operation of the belt conveyor, compensate the dynamic load when the tape starts and brakes, and provide the necessary stroke for the re-joining of the tape, but also It can also automatically correct the deviation of the belt, and prevent the downtime caused by the friction between the conveyor belt and the frame and the idler bracket, the wear of the edge rubber, the tearing of the belt, and the spilling of materials.

Description

Belt conveyor anti-deviation tensioning device

technical field

The utility model relates to the technical field of conveying equipment, in particular to a belt conveyor anti-deviation tensioning device.

Background technique

The tensioning device is one of the important components of the belt conveyor, which ensures the normal operation, starting and braking of the belt conveyor. Ordinary tensioning device can ensure that the loose edge of the conveyor belt has sufficient tension to prevent slipping; limit the sag of the belt on each support roller; compensate for belt starting, dynamic load in the moving conveyor belt, and belt rejoining Provide the necessary stroke, but when the belt conveyor is running, the deviation of the belt is the most common fault. The tensioning device does not have the function of automatic deviation adjustment. The effect of the automatic deviation adjustment idler currently in use is not timely and obvious. At present When solving the problem of belt deviation, it is usually time-consuming and laborious to adjust the position of the bearing roller group and the position of the driving roller and the redirecting roller, and the problem of belt deviation cannot be completely solved.

Utility model content

The technical problem to be solved by the utility model is to overcome the defects of the prior art, and provide a belt conveyor anti-deviation tensioning device that can realize the two-in-one functions of tensioning and deviation correction at the same time.

The technical solution of the utility model is: a belt conveyor anti-deviation tensioning device includes a tensioning frame on which a rotary frame bearing seat is fixed, and a bearing is arranged in the rotary frame bearing seat, and the rotating The lower end of the frame is inserted into the bearing, the slewing frame is provided with a tensioning roller, and the two ends of the tensioning roller are installed in the roller bearing seat through bearings, and the two ends of the slewing frame are provided with vertical rollers on the same side as the roller bearing seat; Also horizontally be provided with two pulleys on the said tension vehicle frame.

Preferably, four wheels parallel to each other are installed at the bottom of the tension frame.

The utility model can not only provide the necessary tension force for the belt conveyor, ensure the tension required for the normal operation of the belt conveyor, compensate the dynamic load when the tape starts and brakes, and provide the necessary stroke for the re-joining of the tape, but also It can also automatically correct the deviation of the belt, and prevent the downtime caused by the friction between the conveyor belt and the frame and the idler bracket, the wear of the edge rubber, the tearing of the belt, and the spilling of materials.

Among them: 1. Tensioning frame, 2. Slewing frame bearing seat, 3. Bearing, 4. Slewing frame, 5. Tensioning roller, 6. Roller bearing seat, 7. Vertical roller, 8. Pulley, 9. Wheel.

Detailed ways

As shown in Fig. 1 and Fig. 2, the belt conveyor anti-deviation tensioning device includes a tensioning frame 1, on which a rotary frame bearing seat 2 is fixed, and the rotary frame bearing seat 2 is provided with Bearing 3, the lower end of the slewing frame 4 is inserted into the bearing 3, the slewing frame 4 is provided with a tension roller 5, and the two ends of the tension roller 5 are installed in the roller bearing seat 6 through bearings, and the two ends of the slewing frame 4 are connected to Vertical rollers 7 are arranged on the same side of the roller bearing housing 6; two pulleys 8 are also arranged horizontally on the tensioning vehicle frame 1 .

Preferably, four wheels 9 parallel to each other are installed on the bottom of the tension frame 1 .

When the conveyor belt deviates, the edge of the conveyor belt is in contact with the vertical roller 7, and the rotary frame 4 is driven to rotate around the rotary frame bearing seat 2 by means of friction (vertical roller rotation), so that the angle between the axis of the pulley 5 and the axis of the conveyor is Changes, so that the conveyor belt moves to the center, corrects its deviation, and reduces the accident rate caused by the deviation of the belt; the whole machine uses the pulley 8 and the steel wire rope to pull the belt along the longitudinal direction of the conveyor with a heavy hammer to provide suitable tension. Force; the four parallel wheels 9 installed on the bottom of the tensed vehicle frame 1 are in rolling contact with two parallel tracks, which can realize the overall translation.

Claims (2)

1. anti-deviation take-up device of belt conveyer, it is characterized in that: comprise the tension vehicle frame, be fixed with the turret mount bearing seat on the tension vehicle frame, be provided with bearing in the described turret mount bearing seat, insert in the bearing turret mount lower end, described turret mount is provided with tension drum, and in the drum shaft bearing, described turret mount two ends and drum shaft bearing homonymy are provided with edger roll by bearing installation at the two ends of tension drum; The level of going back on the described tension vehicle frame is provided with two pulleys.
