Contact type limiting device of coke pusher

Abstract

The invention discloses a contact type limiting device of a coke pusher. The device comprises a coke pushing rod, a base and a coke oven, wherein one side of the coke pushing rod is fixedly connected with a first electric hydraulic rod, the upper end of the base is fixedly connected with a supporting plate, the upper end of the supporting plate is fixedly connected with a second electric hydraulic rod, one side of the coke pushing rod is provided with a limiting assembly, a protective cover is fixedly connected to one side of the coke oven, a limiting switch is arranged in the protective cover, the push rod corresponds to the limiting switch, and an L-shaped limiting rod is fixedly connected to the outer wall of the coke pushing rod. When the device is in use, the stroke of the coke pusher is controlled by the limiting switch, and the limiting switch is in the protective cover so that influences of high temperature and dust on the limiting switch are avoided; the damage to the limiting switch is reduced by arranging the limiting assembly with a buffering function, the coke pushing rod can be lifted, and the coke pushing device is convenient to maintain and use.

Description

technical field [0001] The invention belongs to the technical field of coking equipment, and in particular relates to a contact-type limiting device for a coke pushing car. Background technique [0002] Coking is to add coal into the coke oven through a side-loading coal car on one side of the coke oven. After a period of high-temperature dry distillation to produce coke, the coke is pushed out by a coke pusher, and then the coke oven is used for the next step. Coaling operation. In the process of pushing the focus, the stroke of the focus push rod often needs to be controlled very accurately, otherwise it will cause many production accidents. Unable to operate normally, causing the coke pusher to stay in the coke oven for a long time and burn out. In severe cases, the furnace wall will be damaged, and even the equipment connected to the coke on the other side of the coke oven will be overturned, causing unpredictable production accidents and affecting the coke oven.

Problems solved by technology

In the process of pushing the focus, the stroke of the focus push rod often needs to be controlled very accurately, otherwise it will cause many production accidents. Unable to operate normally, causing the coke pusher to stay in the coke oven for a long time and burn out. In severe cases, the furnace wall will be damaged, and even the equipment connected to the coke on the other side of the coke oven will be overturned, causing unpredictable production accidents and affecting the coke oven. Normal production reduces the production efficiency of the coking plant, so accurate control of the stroke of the push rod is a very important task in the push process

[0003] At present, the stroke control of the coke pusher is generally controlled by a limit device installed on the outside of the cart, but the existing limit device is a very sensitive instrument, and the coke pusher has long been exposed to high temperature and dust Working in the environment, it is difficult to avoid the failure of the limit device. Once the failure occurs, the stroke of the focus lever will be uncontrollable, and the consequences will be unimaginable;

[0004] Existing limit devices are generally provided with a limit switch for controlling the stroke of the coke pushing car, and the limit switch on the coke pushing car is used to touch the limit switch to limit the coke pushing car. When the limit device touches the limit switch, it is easy to cause damage to the limit switch, so that the limit switch fails, and it is impossible to limit the position of the coke pushing car, which is very inconvenient to use, and the existing coke pushing car is generally bulky It is relatively large, and once the limit device is damaged or needs to be repaired, it will be very troublesome to maintain, and maintenance personnel are required to perform maintenance at high altitudes, and there are certain potential safety hazards. Therefore, we propose a contact limit device for the coke pusher to solve the problem in the prior art. existing problems
