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
The present invention relates to the de-chain fender guard of a kind of pipeline apron conveyer infrared ray.
Background technology
Pipeline apron conveyer is in airtight pipeline, to carry out the equipment of material transportation, is the advanced load transfer device of saving energy consumption, stable performance in delivery system, is widely used in chemical industry, chemical fibre, and agricultural chemicals ore, food industry, building materials is waited until industry.Can be conveying powdered, the bulk material such as fine granularity and fritter shape.Can level, inclination and vertical cartel carry.The carrier bar of pipeline apron conveyer connects by chain, by sprocket wheel, through chain-driving carrier bar transported material, still when non-normal use pipeline apron conveyer, there will be chain landing from sprocket wheel, damages the problem of scraper plate, affects the use of conveyer.
Summary of the invention
In order to address the above problem, the invention provides the de-chain fender guard of a kind of pipeline apron conveyer infrared ray.
Technical scheme of the present invention realizes in such a way:
A kind of pipeline apron conveyer infrared ray takes off chain fender guard; it is characterized in that comprising infrared emission tube, infrared receiver tube and PLC; infrared emission tube and infrared receiver tube are symmetricly set on interior each carrier bar running orbit of drive case both sides of side on the lower side; infrared receiver tube is connected with PLC, and PLC is used for controlling pipeline apron conveyer power supply.
The infrared ray that described infrared emission tube sends is not blocked by the carrier bar in orbit.
Principle of work: pipeline apron conveyer is in normal course of operation, infrared receiver tube is received the infrared signal that infrared emission tube sends, infrared signal is converted to electric signal, and PLC receives the electric signal that infrared receiver tube passes out, and connects apron conveyer power supply.When carrier bar landing from sprocket wheel, carrier bar downward bias from orbit, block the infrared ray that infrared emission tube sends, infrared receiver tube does not receive infrared ray, PLC does not receive the electric signal that infrared receiver tube passes out, cut off immediately conveyer working power, conveyer quits work.
Beneficial effect: apparatus of the present invention are highly sensitive, from de-chain to cutting off the electricity supply, the out-of-work process of conveyer is extremely short, occurs to recover to be normally also easy to after de-chain fault.
Accompanying drawing explanation
Fig. 1 is the de-chain fender guard structure front elevation of pipeline apron conveyer infrared ray.
In Fig. 1,1-carrier bar, 2-infrared emission tube, 3-infrared receiver tube, 4-drive case, 5-PLC.
Fig. 2 is the de-chain fender guard structure side view of pipeline apron conveyer infrared ray.
In Fig. 2,1-carrier bar, 2-infrared emission tube, 4-drive case.
The specific embodiment
The present invention is below further described embodiment in connection with accompanying drawing:
As illustrated in fig. 1 and 2; a kind of pipeline apron conveyer infrared ray takes off chain fender guard; it is characterized in that comprising infrared emission tube 2, infrared receiver tube 3 and PLC 5; infrared emission tube 2 and infrared receiver tube 3 are symmetricly set on interior each carrier bar 1 running orbit of drive case 4 both sides of side on the lower side; infrared receiver tube 3 is connected with PLC 5, and PLC 5 is for controlling pipeline apron conveyer power supply.
The infrared ray that described infrared emission tube 2 sends is not blocked by the carrier bar 1 in orbit.
Pipeline apron conveyer is in normal course of operation, infrared receiver tube 3 is received the infrared signal that infrared emission tube 2 sends, infrared signal is converted to electric signal, and PLC 5 receives the electric signal that infrared receiver tube 3 passes out, and connects apron conveyer power supply.When carrier bar 1 landing from sprocket wheel, carrier bar 1 downward bias from orbit, block the infrared ray that infrared emission tube 2 sends, infrared receiver tube 3 does not receive infrared ray, PLC 5 does not receive the electric signal that infrared receiver tube 3 passes out, cut off immediately conveyer working power, conveyer quits work.
Apparatus of the present invention are highly sensitive, and from de-chain to cutting off the electricity supply, the out-of-work process of conveyer is extremely short, occur to recover to be normally also easy to after de-chain fault.
