Embodiment Construction

[0013] Below the present invention will be further described embodiment in conjunction with accompanying drawing:

[0014] Such as figure 1 with 2 As shown, an infrared off-chain protection device for a pipeline chain plate conveyor is characterized in that it includes an infrared emitting tube 2, an infrared receiving tube 3 and a PLC 5, and the infrared emitting tube 2 and the infrared receiving tube 3 are arranged symmetrically in the drive box 4 On both sides of the lower running track of each chain plate 1, the infrared receiving tube 3 is connected to the PLC 5, and the PLC 5 is used to control the power supply of the pipeline chain plate conveyor.

[0015] The infrared rays emitted by the infrared emitting tube 2 are not blocked by the chain plate 1 in the running track.

[0016] During the normal operation of the pipeline chain plate conveyor, the infrared receiving tube 3 receives the infrared signal sent by the infrared emitting tube 2, and converts the infrared si...

Abstract

The invention discloses an infrared chain displacement protector for a pipeline chain-scraper conveyor. The infrared chain displacement protector is characterized by comprising an infrared transmitting tube, an infrared receiving tube and a PLC. The infrared transmitting tube and the infrared receiving tube are symmetrically disposed on two sides below a chain-scraper moving trajectory in a drive box. The infrared receiving tube is connected with the PLC which is used for controlling power of the pipeline chain-scraper conveyor. The infrared chain displacement protector is highly sensitive, the process of from chain displacement to power-off and stoppage of the conveyor is very short, and recovery from failure of chain displacement is very easy.

Description

technical field [0001] The invention relates to an infrared off-chain protection device for a pipeline chain plate conveyor. Background technique [0002] Pipeline chain plate conveyor is a device for material transportation in a closed pipeline. It is an advanced conveying equipment that saves energy and has stable performance in the conveying system. It is widely used in chemical industry, chemical fiber, pesticide ore, food industry, building materials and other industries. . It can transport bulk materials such as powder, small granules and small blocks. It can be conveyed horizontally, inclined and vertically. The chain plate of the pipeline chain plate conveyor is connected by a chain, and the chain plate is driven by the sprocket to transport materials through the chain. However, when the pipeline chain plate conveyor is used abnormally, the chain will slip from the sprocket and damage the scraper. Conveyor use. Contents of the invention [0003] In order to sol...
