Problems solved by technology

[0006] The load of the transmission rod is affected by the condition of the exchange system equipment itself, which will gradually increase, and even cause the deformation of the oil cylinder foundation of the exchange system, the change of the exchange stroke, the failure of the transmission rod, etc., resulting in the shutdown of the reversing machine

Embodiment

[0030] Example: figure 1 As shown, the 7# coke oven of Taiyuan Iron and Steel Coking Plant adopted the following steps to measure the resistance of the rods in March 2011:

[0031] 1. Collect the original data of the lengths of the 4 transmission rods A, B, C, and D of the exchange transmission system of the 7# furnace respectively. The original data of the length is the length of the 4 transmission rods when they leave the factory. Among them, the length of A is 4.36 meters; the length of B is 122.8 meters; the length of C is 18.3 meters; the length of D is 11.8 meters; L=4.36 meters+122.8 meters+18.3 meters+11.8 meters=157.26 meters;

[0032] 2. Determine the reference point: that is, mark the two end positions of each tie rod under the condition of no force;

[0033] 3. When the green direction is heated, after turning from the red direction to the green direction, the D tie bar is in a stressed state, and the position of the two ends of the D tie bar is measured;

Abstract

The invention relates to a resistance measurement method for a transmission pull strip of a coke oven reversing machine and belongs to a coke oven process. The resistance measurement method comprises a first step of measuring deformation delta L of the transmission pull strip in a stressed state and a second step of calculating pulling force F of the transmission pull strip according to the equation that F=E*S*delta L / L, wherein E is elasticity modulus; S is the sectional area of the transmission pull strip; the unit is mm2; delta L is the deformation of the transmission pull strip in the stressed state; and L is an original length of the transmission pull strip. According to the resistance measurement method, faults of an exchange transmission system can be avoided. The resistance measurement method is simple to operate and easy to popularize, and only a ruler or a measuring tape is required.

Description

technical field [0001] The invention belongs to the coke oven process, and in particular relates to a method for measuring the drag resistance of a coke oven reversing machine. Background technique [0002] The commutator is one of the key equipment of the coke oven, which is responsible for exchanging gas and waste gas every 20 minutes to make the temperature of the coke oven uniform and stable. If the coke oven is compared to the human body, then the reversing machine is the heart of the body. After the reversing machine stops due to failure, it will cause damage to the coke oven itself. In severe cases, it will affect the life of the coke oven. Therefore, the reversing machine Stable operation is crucial for coke ovens. [0003] During the reversing process of the coke oven, the reversing machine controls the hydraulic cylinder to pull the transmission rod, and drives the exchange equipment such as the exhaust gas thallium, air door and gas exchange cock of the heating s...
