Description

A device for replacing rubber rollers in limited space in metallurgical machinery and equipment

technical field

The utility model belongs to the technical field of maintenance equipment for metallurgical machinery, in particular to a device for replacing rubber rollers in limited spaces in metallurgical machinery.

Background technique

The stainless steel leveling unit of metallurgical enterprises is an important unit to ensure the quality of the final product of stainless steel, and the replaced anti-wrinkle roller (rubber roller) is an important equipment to ensure the surface quality of stainless steel plates. In the daily production process, if the anti-wrinkle roller (rubber roller) Any abnormality on its own surface will directly affect the surface quality of the product and fail to meet the requirements, which may cause the products produced to be downgraded for use or scrapped. Therefore, it is very important to ensure the quality of the roll surface of the anti-wrinkle roll (rubber roll) and the quality of the final product. Replacing the anti-wrinkle roller (rubber roller) is a very important work content in the maintenance work.

At present, in the process of replacing anti-wrinkle rollers (rubber rollers) for stainless steel skin pass units in metallurgical enterprises, there are no other tools except for the use of existing fork-type hydraulic trolleys to transport anti-wrinkle rollers (rubber rollers). Among them, the existing fork-type The main disadvantages of transporting anti-wrinkle rollers (rubber rollers) by hydraulic trolleys are: 1. According to the environment and structure of the site, during the process of transporting anti-wrinkle rollers (rubber rollers) by fork-type hydraulic trolleys, the ground is a grid plate, and there are flat surfaces on the way. Machine jacking device, the fork-type hydraulic trolley travels at different heights during transportation, which may easily cause the anti-wrinkle roller (rubber roller) to fall from the fork-type hydraulic trolley. Second, combined with the role of the anti-wrinkle roller (rubber roller) in this unit, if the surface of the anti-wrinkle roller (rubber roller) is bumped, the roller cannot be used, and it needs to be re-wrapped to meet the surface quality requirements before it can be used online. Its cost of manufacture is higher. Three, in the process of replacing the anti-wrinkle roller (rubber roller) with a fork-type hydraulic trolley, if there is a defect on the roller surface, the production operation will be carried out without being discovered by personnel, resulting in the substandard surface quality of the product, which will seriously affect the economic benefits of the product.

In the process of replacing the anti-wrinkle roller (rubber roller) of the actual leveling unit, the main method is to manually use the fork-type hydraulic trolley to transport the anti-wrinkle roller (rubber roller). To the final quality of the team's products, so ensuring the quality of the roll surface during the replacement of the anti-wrinkle roll (rubber roll) is the key point. If there is a quality problem on the surface of the anti-wrinkle roller (rubber roller), this will not only cause maintenance failure, but also cause economic losses after equipment damage, and in severe cases, it will also affect the product quality of stainless steel production.

Utility model content

The purpose of this utility model is to solve the technical problems existing in the prior art, and provide a device for replacing rubber rollers in limited space in metallurgical machinery and equipment with simple structure and simple replacement, which will not cause damage to the surface of new rollers during installation.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a device for replacing rubber rollers in a limited space in metallurgical machinery and equipment, including a transport trolley body, the transport trolley body includes a body bracket and a body bracket fixed on The wheel shaft at the bottom, the two ends of the wheel shaft are equipped with wheels through bearings, the wheels are located on the track, and a roller bracket is fixed on the car body support.

Further, tow hooks are respectively provided at both ends of the vehicle body bracket.

Further, the two ends of the wheel shaft are respectively provided with snap springs.

Further, arc-shaped roller brackets are longitudinally fixed on the vehicle body support.

Compared with the prior art, the utility model has the following beneficial effects: the device for replacing rubber rollers in a limited space in the metallurgical mechanical equipment of the utility model mainly includes the body of the transport trolley, and the operator only needs to lift the body of the transport trolley to the corresponding support surface and On the corresponding track, the replaced rubber roller is hoisted to the roller bracket on the car body support, which can effectively meet the delivery requirements of the rubber roller while ensuring the quality of the roller surface. Compared with the existing fork-type hydraulic trolley, the utility model greatly reduces the labor intensity of the operators on the one hand and improves the working efficiency; The quality of the product when the equipment is produced. At the same time, the utility model has the advantages of simple structure, low cost, convenient processing, and convenient use, which can effectively ensure the safety of workers and prevent personnel from bumping and hurting due to slipping and falling of rubber rollers during transportation, and has good use value and application prospect.
