AI Technical Summary
The rollers of traditional belt conveyors are prone to deviation after unbalanced load or wear, resulting in material spills and belt edge wear, affecting production efficiency and possibly causing equipment damage.
A push rod type offset adjustment roller device is used, which is connected to the electric control box through an electro-hydraulic push rod. The electro-hydraulic push rod is manually controlled to drive the roller seat to move along the arc guide rail to achieve flexible offset adjustment of the roller.
It reduces the imbalance of the spacing of the roller, improves the stability and transmission efficiency of the conveyor, reduces the drop and accumulation of materials, and reduces the cost of the equipment.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of conveyors, in particular to a push rod type deviation adjusting roller device for a belt conveyor. Background Art
[0002] Rollers are important parts of belt conveyors. There are many types and large quantities of them. They can support the weight of conveyor belts and materials. When working, if the load is unbalanced (such as the center of gravity of the material is offset, the weight is unevenly distributed, etc.), or the surface of the roller is prone to wear after long-term use, especially the parts on both sides of the roller that contact the drum are more seriously worn. Wear will affect the running stability of the roller. Temperature changes, humidity and other factors will also affect the roller, causing the roller to deviate, and the deviation will cause the belt to deviate, resulting in serious material spillage, or the belt edge is prone to wear. This affects production efficiency and may also cause abnormal damage to the main components of the equipment. In the metallurgical, mining, coal, power station, port, building materials, chemical and other industries, for belt conveyors that transport various bulk materials with loose density of 500-2500kg / m3, with a suitable bandwidth of B=500-2600mm and a belt speed of V=0.5-4.5m / s, the traditional deviation adjustment method is to set arc guide rails on both sides of the top of the frame, and roller seats are slid in the arc guide rails, and rollers are set between the roller seats, such as Figure 1 , by setting up a motor in the middle of the frame and driving the telescopic rod to drive the roller seat to move along the arc guide rail, but the motor structure is complex and large in size, resulting in a large spacing between adjacent rollers. Too large a spacing between rollers will cause the material to shake and swing during transportation, and it is very easy for the material to fall and accumulate, affecting the stability of the system. Too large a spacing between rollers will cause the material to stay between adjacent rollers for too long, which also reduces the transmission efficiency of the system, and the cost of the motor is high.
