Abstract

The utility model relates to a deflection detector of the Dry Quenching tank. The utility model is characterized in that an iron induction switch is placed on a lifting platform above the point where the dropping Dry Quenching tank stops. The infrared transmitting tubes of the infrared beam transmitting circuit and the infrared receiving tubes of the infrared beam receiving circuit are placed below the iron induction switch in a same height. The distance between the height and the bottom of the tank when the tank stops dropping is 10to 20mm. The hall sensor is placed on the loading surface of the Dry Quenching truck, and the magnetic stone is placed on the bottom of the Dry Quenching tank. When the tank is loaded on the Dry Quenching truck, the sensor and the magnetic stone are of corresponding position. By using the iron induction switch, the infrared sensor and the hall sensor for collecting the signals of the status of the gate on the bottom of the Dry Quenching tank, the utility model is capable of providing accurate and reliable statistics in detecting the position of the bottom of the Dry Quenching tank.

Description

Burnt jar of deflection pick-up unit of dry coke quenching

Technical field

The utility model belongs to device deflection detection technique, is burnt jar of deflection pick-up unit of a kind of dry coke quenching specifically.

Background technology

After China has issued coking industry access regulations, many dry coke quenching auxiliaries have successively been built up, coke tank truck is an important equipment in the dry quenching system, it is responsible for transporting red Jiao, taking on an important step of forming a connecting link in the coke logistics system, in case burnt jar of deflection accident takes place, not only production causes direct influence to coke oven, also be related to later process as generating electricity and sending vapour, loss often reaches units up to a million.How before fault takes place, to prevent, guarantee rotation coke tank truck reliability of operation and security, become more and more distinct issues.But there is not good solution always yet.

Summary of the invention

The purpose of this utility model provides a kind of can being used on the burnt jar of dry coke quenching, and the higher tilt detecting device of accuracy of detection, to address the above problem.

To achieve these goals, the utility model is made up of magnet on the iron inductive switch on the crane, infrared emission circuit, infrared receiving circuit, the burnt jar and the Hall element on the coke tank truck, be characterized in: the iron inductive switch is positioned at burnt jar of upper edge that stops to locate when falling, the infrared transmitting tube of infrared emission circuit and the infrared receiving tube of infrared receiving circuit are positioned at the same level height of iron inductive switch below, and the vertical range of its bottom was 10-20mm when this level height stopped to burnt jar of whereabouts.

Above-mentioned Hall element is positioned on the loading plane of coke tank truck, and magnet is installed in burnt pot bottom, and when being placed on the coke tank truck for burnt jar, magnet and Hall element are in the relevant position.

Because the utility model adopts iron inductive switch, infrared sensor and Hall element to gather burnt jar of end gate status signal, deliver to PC then and carry out signal Processing, make when the utility model is used for burnt pot bottom position measurement, error is littler, data accuracy is high, safety and stability is high, practical and convenient.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described, but this embodiment should not be understood that restriction of the present utility model.

The utility model is made up of magnet (6) on the iron inductive switch (2) on the crane (1), infrared emission circuit (3), infrared receiving circuit (4), burnt jar (5) and the Hall element (8) on the coke tank truck (7), iron inductive switch (2) is positioned at the upper edge that stops to locate when burnt jar (5) fall, the infrared receiving tube of the infrared transmitting tube of infrared emission circuit (3) and infrared receiving circuit (4) is positioned at the same level height of iron inductive switch (2) below, and the vertical range of its bottom was 10-20mm when this level height fell to stopping to burnt jar (5).When burnt jar (5) fall to its upper edge and iron inductive switch (2) when aliging, PC is handled according to the signal that iron inductive switch (2) sends, burnt jar (5) stop to wait for coke tank truck (7), simultaneously, infrared receiving circuit (4) receives the signal of infrared emission circuit (3), sends PC after opto-electronic conversion to, PC can accurately be judged burnt jar (5) whether run-off the straight in view of the above, in case occur any unusually, all equipment relevant with burnt jar (5) will be out of service at once automatically, and give the alarm.

Hall element of the present utility model (8) is positioned on the loading plane of coke tank truck (7), and magnet (6) is installed in burnt jar (5) bottom, and when burnt jar (5) were placed to coke tank truck (7) and go up, magnet (6) was in the relevant position with Hall element (8).PC is judged burnt jar (5) whether run-off the straight according to the signal of Hall element (8), and deals with.

The content that is not described in detail in this instructions belongs to the those skilled in the art known prior art.

Claims

1, burnt jar of deflection pick-up unit of a kind of dry coke quenching, by the iron inductive switch (2) on the crane (1), infrared emission circuit (3), infrared receiving circuit (4), magnet (6) and the Hall element (8) on the coke tank truck (7) on burnt jar (5) are formed, it is characterized in that: iron inductive switch (2) is positioned at the upper edge that stops to locate when burnt jar (5) fall, the infrared receiving tube of the infrared transmitting tube of infrared emission circuit (3) and infrared receiving circuit (4) is positioned at the same level height of iron inductive switch (2) below, and the vertical range of its bottom was 10-20mm when this level height fell to stopping to burnt jar (5).

2, burnt jar of deflection pick-up unit of dry coke quenching as claimed in claim 1, it is characterized in that: Hall element (8) is positioned on the loading plane of coke tank truck (7), magnet (6) is installed in burnt jar of (5) bottom, when burnt jar (5) were placed on the coke tank truck (7), magnet (6) was in the relevant position with Hall element (8).
