Coke tank positioning detection device and detection protection method

Abstract

The invention relates to a coke tank positioning detection device, which comprises a coke tank position detector and a ground alignment detector, wherein the coke tank position detector comprises a coke tank absolute value position encoder installed on a coke tank transmission system and capable of rotating along with a coke tank, a verification trigger installed on the coke tank, a verification detection limiter installed on a coke tank trolley and an auxiliary mechanical transmission device, and the absolute value position encoder is connected to a vehicle-mounted control system, and is usedfor calculating the number of the turns of the rotation of a coke tank rotation speed reducer, calculating the rotation angle of the coke tank by converting the reduction ratio and the like, and participating in the control functions of speed regulation, zero calibration, positioning and the like.

Description

technical field [0001] The invention relates to a detection device, in particular to a coke tank positioning detection device and a detection and protection method, belonging to the field of electrical equipment control. Background technique [0002] In the production process of CDQ in coke ovens, the work of receiving red coke in the coke oven area and filling the coke tanks in the CDQ area is completed by relying on the carrier vehicle to drag the coke tank trolley. The structure of the carrier car and the coke tank trolley is as follows: figure 1 As shown, the coke tank trolley has a coke tank rotating table 7, a rotatable coke tank and a spreader and other components. There are two coke tank bottom doors 3 at the bottom of the coke tank, and there are locking grooves 4 on the bottom door. Groove hook 5 and lifting lug 6 are arranged. When the coke pot was on the coke pot rotating table 7, the two bottom doors 3 of the coke pot were closed by the dead weight of the coke...

AI Technical Summary

Problems solved by technology

[0004] 1. The on-board control system relies on the on-board switch positioning detection signal for chain protection, and once the switch limit is damaged, it will easily lead to positioning failure

[0005] 2. There is no reliable monitoring method on the ground to detect the position of the rotating coke tank. Before the hoist lifts the coke tank, it often relies on manual observation to see if the coke tank under the hoist derrick is at the positioning point. The negligence of manual observation is likely to cause accidents

[0006] 3. The control systems of the carrier vehicle and the hoist are independent of each other, and they cannot cooperate reliably. There is no reliable anti-deflection tank protection method. Once the coke tank is deflected and the carrier vehicle issues a lifting command for effective detection, the hoist can still Carrying out tank lifting operations, causing safety hazards to production
