Description

Technical Field

[0001] The utility model relates to the technical field of coke pushing car devices, in particular to a coke pushing car sliding shoe for a coking plant. Background Art

[0002] The coke pusher works on the coke oven side and is used to push out the mature coke in the carbonization chamber. Due to the long length of the coke pusher rod, when the coke pusher rod enters the carbonization chamber to a certain distance, the head and front end of the coke pusher rod will sink. At this time, the sliding shoe device is needed to play a supporting role, give the coke pusher rod an upward force to lift it up, and completely push out the coke at the bottom of the carbonization chamber. The original sliding shoe device design consists of three parts: the upper part of the sliding shoe, the lower part of the sliding shoe, and the sliding shoe bottom plate. Since the internal temperature of the coke oven is as high as about 1100℃, the sliding shoe bottom plate directly contacts the bottom of the carbonization chamber and the coke during the coke pushing operation, so there are the following problems:

[0003] 1. The overall material of the ordinary sliding shoe bottom plate is 16Mn or ZGNMn13, which has poor wear resistance and short service life. The replacement frequency is high and the time is long, and more manual daily inspections are required;

[0004] 2. The bottom plate of the sliding shoe in the lower device of the sliding shoe is connected with the lower device of the sliding shoe by 8 sets of bolts. Due to the different degrees of wear of the front and rear of the sliding shoe bottom plate, when one side of the sliding shoe bottom plate is worn close to the bolt, the sliding shoe bottom plate needs to be replaced, otherwise the bottom plate will fall into the carbonization chamber during the continued operation;

[0005] 3. The front and rear ends of the bottom plate of the sliding shoe are obtuse, which has a greater impact on it when entering the carbonization chamber, and it is easy to cause damage to the bottom of the carbonization chamber and it is difficult to repair after damage;

[0006] Therefore, a coke pusher shoe for a coking plant is provided to solve the above problems. Summary of the invention

[0007] The technical problem to be solved by the utility model is that the overall material of the ordinary sliding shoe bottom plate is 16Mn or ZGNMn13, which has poor wear resistance, short service life, high replacement frequency and long time, and requires more manual daily inspections; the sliding shoe bottom plate in the sliding shoe lower device is positioned and connected with the sliding shoe lower device by 8 groups of bolts. Since the wear degree of the front and rear of the sliding shoe bottom plate is different, when one side of the sliding shoe bottom plate is worn close to the bolt, the sliding shoe bottom plate needs to be replaced, otherwise the bottom plate will fall into the carbonization chamber during the continued operation; the front and rear ends of the sliding shoe bottom plate are obtuse, and the impact on it is large when entering the carbonization chamber, which is easy to cause damage to the bottom of the carbonization chamber and difficult to repair after damage; therefore, a sliding shoe for a coke pusher car in a coking plant is provided, and the sliding shoe for a coke pusher car in a coking plant comprises:

[0008] A sliding shoe housing, a sliding shoe lower member and a sliding shoe bottom plate member, wherein the sliding shoe lower member is sleeved on the outside of the sliding shoe housing, the sliding shoe bottom plate member is arranged below the sliding shoe lower frame, and the sliding shoe bottom plate member and the sliding shoe lower member are integrally formed;

[0009] The sliding shoe bottom plate component includes a mounting layer and a wear-resistant layer, and the wear-resistant layer is arranged in contact with the lower surface of the mounting layer.

[0010] Furthermore, the wear-resistant layer and the installation layer have the same structure, and both the front and rear sections of the installation are provided with arc-shaped guide sections.

[0011] Furthermore, the sliding shoe housing is provided with a first connecting hole.

[0012] Further, the lower component of the sliding shoe includes a first connecting plate, a second connecting plate and a connecting side plate, the upper end of the first connecting plate is provided with a second connecting hole, the lower end of the first connecting plate is fixedly connected to the mounting layer, second connecting plates are symmetrically fixedly provided on both sides of the first connecting plate, the upper end of the second connecting plate is fixedly connected to the connecting side plate, the lower end of the second connecting plate is fixedly connected to the mounting layer, the upper half of the connecting side plate is fixedly connected to the sliding shoe shell, and the lower end of the connecting side plate is fixedly connected to the mounting layer.

[0013] Furthermore, the first connection hole and the second connection hole are fixedly connected by bolts.

[0014] Furthermore, the thickness of the sliding shoe bottom plate component is 15 mm.

[0015] Furthermore, the wear-resistant layer is formed by surfacing welding of highly wear-resistant material.

[0016] Furthermore, a lifting lug is provided on the upper end surface of the connecting side plate.

[0017] The implementation of this utility model has the following beneficial effects:

[0018] When the utility model is in use, the lower part of the sliding shoe and the sliding shoe bottom plate are designed as a whole, replacing the positioning and installation structure with 8 groups of bolts in the original structure, which can prevent the sliding shoe from falling into the carbonization chamber when it is worn to the bolts; the front and rear corners of the bottom plate are changed to arc transition, which reduces the impact when entering the carbonization chamber, prevents damage to the carbonization chamber, and extends the service life of the coke oven carbonization chamber; the original bottom plate material is changed, and the bottom layer of the bottom plate is a surfacing layer, and high-wear-resistant material is used for surfacing, so that its service life is greatly extended, and the replacement frequency and labor waste are reduced.
