A contact limit device for coke pusher

Abstract

The invention discloses a contact-type limiting device for a coke pusher, which comprises a coke pusher rod, a base and a coke oven. One side of the coke pusher rod is fixedly connected with a first electrohydraulic rod, and the upper end of the base is fixedly connected with a A support plate, the upper end of the support plate is fixedly connected with a second electro-hydraulic rod, one side of the coke pushing rod is provided with a limit assembly, one side of the coke oven is fixedly connected with a protective cover, and the inside of the protective cover A limit switch is set, the ejector rod and the limit switch are set correspondingly, and an L-shaped limit rod is fixedly connected to the outer wall of the coke pushing rod. And the limit switch is located inside the protective cover, avoiding the influence of high temperature and dust on the limit switch, and by setting the limit component with buffer function, the damage to the limit switch is reduced, and the focus pusher can also be adjusted. Lifting, easy maintenance, very convenient to 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
