Description

A device for reducing the split length of the transport belt

technical field

The utility model belongs to the technical transformation of belt conveyors of industrial enterprises, and relates to a device for reducing the split length of conveyor belts.

Background technique

Belt conveyor, also known as rubber belt conveyor, is a continuous transportation equipment and a general-purpose equipment. It is widely used in steel, aluminum, coal, power plants, cement, grain, and light industrial production lines. The conveying length ranges from tens of meters ranging from several thousand meters. The conveyor belt is the most important core component of the belt conveyor, accounting for more than 80% of the maintenance and replacement costs of the belt conveyor. Affected by the complex characteristics of the transported materials, hard foreign matter entering the material may cut through the belt for a long distance and cause the belt to be scrapped for a long distance. Affect normal production, and invest a lot of cost to replace the conveyor belt.

At present, various industries usually use iron remover to remove magnetic foreign matter brought by materials, so as to reduce belt splitting accidents. However, the iron remover cannot solve the problem of transporting sharp hard ores or non-magnetic sharp foreign objects. For example, the liner plate dropped by the ore hopper will cause the belt at the feeding point of the ore hopper to be scratched.

detailed description

As shown in Figure 1, a device for reducing the split length of the conveyor belt, the device includes a support base 1, a lower spring positioning seat 2, an upper spring positioning seat 3, a spring 4, a positioning shaft 5, a material receiving platform 6, and an impact plate 7. The emergency switch 8, the support base 1 is fixed on the frame beam 9 of the conveyor, the lower spring positioning seat 2 and the upper spring positioning seat 3 are relatively fixed on the support base 1, the bottom of the material receiving platform 6, and the spring 4 The two ends are set on the lower spring positioning seat 2 and the upper spring positioning seat 3 respectively, and the positioning shaft 5 is sequentially connected with the material receiving platform 6, the upper spring positioning seat 3, the lower spring positioning seat 2, and the support base 1 from top to bottom, and the impact plate 7 is fixed. The material receiving platform 6 and the emergency switch 8 are set on the support base 1, the emergency switch 8 is connected in series with the power supply of the conveyor control circuit 10, the belt is split and the impact plate 7 is in contact with the contact of the emergency switch 8 when the material receiving platform 6 is in the material receiving state , the emergency switch 8 is triggered to shut down the conveyor motor; After the mine funnel 13, about 3-4 meters away from the feeding funnel.

As shown in Figures 3 and 4, the faulty foreign object 14 fell from the ore feeding funnel 13, and the faulty foreign object 14 cut through the belt. If the conveyor continues to run and the belt moves forward, the belt will be cut all the time, and long holes will appear. If it is not discovered in time, the entire belt will be scrapped. After the device 11 is installed, the cut belt runs to the top of the device 11 and continuously leaks material from the gap, the material receiving platform 6 carries the material, and the weight of the material receiving platform 6 increases after adding the falling material, and the spring 4 is compressed , the impact plate 7 is connected with the material bearing platform 6, the compression amount of the spring 4 is equal to the downward movement distance of the impact plate 7, the impact plate 7 touches the contact of the emergency switch 8, the emergency switch 8 is normally closed, and is After triggering and opening, the power supply of the conveyor is interrupted, the conveyor stops, and the belt will not be cut further, so that the belt of hundreds of meters and kilometers is only cut a few meters long, which greatly reduces the loss.

Further, as shown in Fig. 2, the material receiving platform 6 has a mesh and is surrounded by a rectangular frame, so that the device is light in weight.

In order to further increase the reliability of the device, there are four sets of lower spring positioning seat 2, upper spring positioning seat 3, spring 4, and positioning shaft 5, which are respectively located at the four corners of the material receiving platform 6. After the material leaks, the falling point is uneven. As long as any one There is sinking behind the corner load, and the spring pressure accident switch 8 is triggered. There are two groups of impact plate and emergency switch 8, each group is arranged near the spring, and the two groups are connected in series with each other, and then connected in series with the machine control circuit power supply, and the two groups are set to realize double insurance.

Application example: The device is applied to 14 key belt conveyors in the Sorting and Sintering Plant of Hongxing Iron and Steel Co., Ltd. of JISCO Group. On February 13, 2016, the conveyor belt of 1# was cut through 3 meters, and the total length of the conveyor belt was 318 meters; on April 17, 2016, the original 2# belt conveyor was cut through 4 meters, and the total length of the conveyor belt was 168 meters; 2016 On December 17, 2018, the 3# belt conveyor was selected to cut through 1.4 meters and then shut down for protection. The length of the conveyor belt was 530 meters. The three cut-through accidents reduced the belt tearing by about 1,000 meters in total. Practice has proved that this device can effectively reduce the long-distance scratching accidents of the belt, especially suitable for tearing accidents caused by sharp and hard materials or foreign objects penetrating the conveyor belt at the discharge point of the ore (material) hopper of the belt conveyor.
