Description

Round tube belt conveyor return flat belt idler device

technical field

The utility model relates to the field of circular tube belt conveyors, in particular to a return flat belt idler device in the transition section of the circular tube belt conveyor. the

Background technique

The circular tube belt conveyor is a new type of environmentally friendly continuous conveyor. During the material running process, the conveyor belt is kept in a circular tube shape, and it is flattened at the head and tail rollers. There is a transition section between flattening and pipe forming. The length of this transition section is related to factors such as the diameter of the pipe, the material of the conveyor belt, and the tension of the conveyor belt. It is also related to the number and location of the loading and unloading points, and the tension. There is a relationship between the form and position of the tightening device and other factors. When the transition section is relatively long, the current structure and arrangement of some idlers adopt the structure of the flat belt conveyor shown in Figure 1, as follows: the upper bearing section adopts 35° grooved idlers, and the return section adopts return flat support The installation position of the roller and the idler roller is the two ends of the idler shaft, and the hanging brackets at both ends are usually fixedly connected with the frame.

Usually, the conveyor belt width of the circular tube belt conveyor is larger than that of the flat belt conveyor, and the idler rollers of the circular tube belt conveyor carrying the return flat belt also increase accordingly, especially for large diameter circular tubes. Belt conveyors are more obvious. When the length of the return flat idler is increased, the manufacture of the idler is required to ensure the coaxiality of both ends, and the manufacturing precision is high; in the case of ensuring the bearing capacity, the shaft diameter of the idler needs to be increased or the material with better stiffness should be selected to improve Reduce the consumption of steel and increase the weight of the round pipe belt conveyor; due to the accuracy problem in the manufacturing and installation process, the service life of the bearing is short; after the roller skin is partially worn, the entire roller must be replaced. Operating costs increase.

Utility model content

In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a return flat belt idler device of a circular tube belt conveyor.

In order to solve the above-mentioned technical problems, the return flat belt idler device of the round pipe belt conveyor provided by the utility model has at least a fixed frame connected to the frame of the round pipe belt conveyor; at least two idler rollers.

Further, in the round tube belt conveyor return flat belt idler device provided by the utility model, the frame of the round tube belt conveyor has a waist-shaped hole for installing the fixing frame, and the two ends of the fixing frame It is connected with the frame of the circular tube belt conveyor through bolts, and its installation position can be adjusted in height within the range of the waist hole.

Further, the round pipe belt conveyor return flat belt idler device provided by the utility model also has at least four support frames detachably connected to the fixed frame, and the support frame has a support for supporting the idler roller. plate; a stiffener plate located in the middle of the support plate; the upper part of the support plate has a slot for installing the idler; the shafts at both ends of the idler have matching hooks, and the two ends of the idler are connected to the The support plate is clamped.

The beneficial effects of the utility model: the long idler is replaced by more than two short idlers, the bearing capacity is high, the material is saved, the processing precision requirements of the idler are reduced, and the service life of the bearing is longer; it can be replaced in a targeted manner if the local wear is serious Compared with replacing the whole long idler, it is more economical; it is easy to standardize the type of idler, and set it to be the same as the hexagonal idler of the round tube belt conveyor, which is convenient for interchange; There are upper and lower long waist round holes, the installation height of the roller can be adjusted up and down, and the installation and adjustment are convenient.
