Conveyer belt energy saving property testing device and sample loading and unloading method

Abstract

The invention relates to a conveyor belt energy saving property testing device, including a frame, an active roller mounted on the frame, a driven roller, and a conveyor belt mounted on the active roller and the driven roller. The active roller and the driven roller are detachably mounted on the frame. The active roller and the driven roller can slide relatively. Inners sides of installation positions of the active roller and the driven roller on the frame are fixedly provided with a platform for dismounting the active roller and the driven roller. A roller hoisting device is arranged beside the frame. According to the invention, an annular conveyor belt sample can be conveniently mounted, and the structure of the testing device is simplified as much as possible. The invention adopts the method for hoisting the active roller and the driven roller of the testing device, adopts special-purpose rotary supports and movable holding rods, can mount the annular sample on the testing device and dismount the annular sample from the testing device according to predetermined steps, reduces the number of dismounted parts, and guarantees the precision of the overall testing device.

Description

technical field [0001] The invention relates to a conveyor belt energy-saving test device and a sample loading and unloading method. Background technique [0002] With the continuous development of long-distance transportation, the running resistance of the conveyor belt has attracted widespread attention. The research shows that when the conveyor belt passes through the idler roller, the energy loss caused by the depression of the contact part between the lower cover rubber and the idler roller accounts for about 60% of the energy loss of the entire conveying system due to the pressure of the material when the conveyor belt passes through the idler roller. Therefore, the coal, mining, conveyor belt industries, as well as many colleges and scientific research institutions have been studying the indentation resistance of conveyor belts as an important topic. In order to reduce the conveying resistance, many manufacturers have developed various types of energy-saving conveyor...

AI Technical Summary

Problems solved by technology

[0020] ①The existing test device for measuring the indentation resistance of the conveyor belt does not exclude the rolling resistance of the pressure roller itself, and the measured horizontal force is actually the resultant force of the two forces, the circumferential force and the indentation resistance generated by the rolling resistance itself , the measurement error is large

[0021] ②Most of the existing methods for measuring the resistance of conveyor belt idlers cannot completely simulate the load conditions of the actual operation of the idler and the required test device has a complex structure, which cannot be applied to the test device for testing endless conveyor belt samples

[0022] ③The existing method for installing the endless belt sample needs to dismantle a large number of parts on the test device. Repeated movement of the frame will also reduce the accuracy of the entire device, making it difficult to popularize and apply

[0023] ④The method of vulcanizing the joint of the sample on the test device, the conveyor belt, especially the steel wire rope conveyor belt, has a strict joint process, which requires high technical personnel. Since it is not operated in a professional production plant, the technology and equipment cannot be guaranteed. The strength and flatness of the sample joint will be greatly affected, making the sample run unstable during the test, and sometimes the length of the connected sample may even appear inconsistent on the left and right sides (in the shape of a bell mouth), causing the sample "Deviation" during the test, in severe cases, the test cannot be carried out
