[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0024] In order to thoroughly understand the present invention, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0025] Reference Figure 1-2 As shown, the utility model provides a multi-stand continuous rolling mill cleaning system, each rolling mill 1 is equipped with a water system interface and a track 2 leading into the inner cavity of the rolling mill 1, and the rolling mill cleaning system includes an all-round cleaning trolley 100 capable of entering the inner cavity of the rolling mill 1 and a lifting cleaning nozzle 200 located between adjacent rolling mills 1. The lifting cleaning nozzle 200 can be lifted up and down to clean the outer shell of the rolling mill 1.

[0026] Continue reading Figure 2-5 As shown, the all-round cleaning trolley 100 is provided with a mobile frame 110, and two front and rear groups of running wheels 111 cooperating with the track 2 are arranged at the bottom of the mobile frame 110, one group of running wheels 111 is a driving wheel and is connected to the driving device 112, and an annular spray beam 120 and a water pipe reel 130 are installed on the front and rear sides of the mobile frame 110, and a water pipe is wound on the water pipe reel 130, one end of the water pipe is connected to the water inlet of the annular spray beam 120, and the other end of the water pipe is connected to the water outlet of the water system interface.

[0027] The annular spray beam 120 is made of a steel pipe with the same shape as the inner cavity of the rolling mill 1. A plurality of fan-shaped nozzles 121 are arranged on the outer side of the steel pipe. A rotating nozzle 122 is arranged in the middle of the annular spray beam 120. The rotating nozzle 122 is connected to the internal pipeline of the steel pipe through a branch pipeline 123.

[0028] In an optional embodiment, the driving wheel is connected to the power output wheel of the driving device 112 through a belt or a chain, and the driving device 112 is provided with a waterproof housing. The driving device 112 can be an electric motor or a pneumatic motor, which can transmit power to the driving wheel through a transmission mechanism, so that the omnidirectional cleaning trolley 100 moves forward and backward on the track 2 to enter and exit the rolling mill cavity. At the same time, in order to ensure the stability and safety of the movement of the cleaning trolley 100, an anti-skid device and a limit switch can be provided on the walking wheel 111 to prevent the cleaning trolley 100 from sliding or colliding during movement.

[0029] Preferably, the inner cavity of the rolling mill 1 and the annular spray beam 120 are both in an inverted "convex" shape, so that the annular spray beam 120 can fit the inner cavity shape of the rolling mill 1, thereby achieving comprehensive cleaning of the inner wall of the rolling mill 1. The fan-shaped nozzles 121 can be evenly arranged along the outer side of the steel pipe to ensure uniform distribution and comprehensive coverage of the cleaning water flow. The rotating nozzle 122 can rotate in the middle of the annular spray beam 120 to clean the hard-to-reach parts in the inner cavity of the rolling mill 1.

At the same time, the water hose reel 130 can also be provided with a tensioning device to ensure the tension and stability of the water hose.

[0031] The flow rate of the water system interface is adjustable to meet different cleaning requirements. For example, in the early stage of cleaning, a larger flow rate can be used to quickly remove oil and dirt; in the later stage of cleaning, a smaller flow rate can be used to finely clean the inner surface of the rolling mill 1. In addition, the water system interface can also be equipped with a filter and a pressure gauge to ensure the purity and stability of the cleaning water quality.

[0032] The annular spray beam 120 is connected to the mobile frame 110 by bolts. In actual applications, the mobile frame 110 is a universal part. The annular spray beam 120 of corresponding shape is customized according to the rolling mill with different inner cavity shapes and installed on the mobile frame 110 to reduce costs.

[0033] The utility model uses the original track of the rolling mill to send the cleaning trolley into the rolling mill. After the current rolling mill is cleaned, the cleaning trolley drives out of the current rolling mill and is lifted by a crane to the next rolling mill for cleaning.

[0034] In summary, the multi-stand continuous rolling mill cleaning system of the utility model realizes efficient and comprehensive cleaning of the interior of the multi-stand continuous rolling mill through the combined use of the omnidirectional cleaning trolley 100 and the lifting cleaning nozzle 200. The system has the advantages of simple structure, convenient operation, good cleaning effect, etc., can significantly improve the production efficiency and product quality of the multi-stand continuous rolling mill, reduce enterprise costs and maintenance costs, and has broad application prospects and promotion value.
