Description

Floor groove polishing equipment and working method

Technical Field

The invention belongs to the technical field of polishing equipment, and particularly relates to floor groove polishing equipment and a working method.

Background

The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

At present, the international trade of foods, medicines and even articles such as high-grade clothing and the like is carried by adopting a refrigerated container. When some goods are transported, weak acid gas emitted by the container can cause corrosion of the surface of the aluminum alloy air duct floor of the container for a long time, if the container is used for transporting other goods again without treatment, the corrosion can pollute the subsequent goods, especially food, so that the floor is required to be replaced or polished, derusted and subjected to corrosion prevention treatment according to the maintenance standard requirements of the refrigerated container.

The prior floor groove structure is shown in fig. 11, the width of the notch of the floor groove is smaller than the width in the groove, the direction indicated by an arrow in the figure is the surface of the floor groove to be polished, and the floor groove is provided with a bottom surface, a side surface, an upper surface and a lower surface; because the positions of the surfaces to be polished are different, the existing high-pressure water gun is difficult to clean, and the problems of more personnel, long labor time, low efficiency, high cost and the like are solved. In addition, various oil stains, article fragments, biological fluids and the like are easy to exist in the floor tank in the container, so that the water washing mode cannot realize complete cleaning.

Still other polishing devices are used to perform polishing to remove rust, for example, patent number CN208019984U discloses an automatic polishing device for a floor of a refrigerated container, which comprises a base, and a driving system, a polishing system and an electrical control system which are installed on the base; the polishing system comprises a motor and a polishing rotating shaft, wherein the polishing rotating shaft is provided with a synchronous pulley, a bearing, a polishing brush clamp and a polishing brush from top to bottom; the motor is connected with a driving synchronous pulley, and the driving synchronous pulley is connected with a slave synchronous pulley of the polishing rotating shaft through a double-sided synchronous belt for transmission; the synchronous pulley is sleeved on the polishing rotating shaft, and a flat key is arranged between the synchronous pulley and the rotating shaft.

However, this technique has the following technical problems:

(1) According to the technology, a motor drives a main synchronous belt pulley to rotate, the main synchronous belt pulley drives a secondary synchronous belt pulley to rotate through a transmission belt, and finally a polishing brush is driven to polish. Therefore, the polishing brush of the technology can only control the polishing equipment to select one surface to be polished to polish through the electric control system, and the simultaneous polishing of the bottom surface, the side surface, the upper surface and the lower surface of the floor groove can not be realized, so that the floor groove is completely polished for a long time, and the polishing efficiency is low.

Moreover, the polishing brush adopted in the technology can only polish the side surface and part of the lower surface of the floor groove. The polishing brush is provided with the shaft, after the polishing brush enters the floor groove, the end part of the shaft can prop against the bottom surface of the floor groove, and the polishing brush cannot contact with the bottom surface of the floor groove, so that the bottom surface of the floor groove cannot be polished. The brush head of the polishing brush in the technology faces to the side face of the floor groove, so even if the polishing brush is aligned to the upper surface of the floor groove, the brush head cannot face to the upper surface, and polishing or poor polishing effect of the upper surface of the floor groove cannot be realized. The polishing range of the technology is limited, the dead angle is large during polishing, and missing positions are easy to occur.

(2) The polishing brush in the technology is fixed in position, abrasion is inevitably generated after the polishing brush is used for a long time, the contact degree between the brush head position of the polishing brush and the polishing surface of the floor groove is different after the abrasion, and the polishing brush cannot be fully contacted with the floor groove and cannot be polished thoroughly. At this time, the polishing brush can be replaced only to ensure the polishing effect, so that the cost is increased.

(3) Part of foreign matters are inevitably reserved in the container floor groove, and if the foreign matters are encountered in the advancing process of the polishing equipment, the polishing equipment is damaged, and the polishing effect of the polishing equipment is affected. The technology does not consider the condition that foreign matters exist in the floor groove, and cannot realize the detection of the foreign matters in the floor groove.

(4) The width of this technique polishing brush is greater than the width of floor groove notch, just so can polish with the side contact of floor groove when entering into the floor inslot, consequently can't directly enter into the floor inslot, need incline when using in with polishing brush stopper in the floor groove, again with the hub connection just can polish, also need pull down the polishing brush again and take out to one side when taking out, the installation is dismantled and is spent for a long time, leads to polishing inefficiency.
