Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of polishing equipment, and particularly relates to a floor groove polishing equipment and a working method. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.

[0003] At present, international trade of food, medicine and even high-grade clothing and other articles is mostly transported by refrigerated containers. When transporting certain goods, the weakly acidic gas emitted by the goods will cause corrosion on the surface of the aluminum alloy air duct floor of the container for a long time. If the container is used again without treatment to transport other goods, the corrosion will pollute the subsequent goods, especially food. Therefore, according to the maintenance standard of the refrigerated container, the floor needs to be replaced or polished, rusted and treated for corrosion.

[0004] The existing floor groove structure is shown in FIG. 1, the slot width of the floor groove is less than the width in the slot, the direction indicated by the arrow in the figure is the surface of the floor groove that needs to be polished, which has a bottom surface, a side surface, an upper surface and a lower surface; due to the different positions of the surfaces to be polished, it is difficult to clean only by using the existing high-pressure water gun, and there are many problems such as more personnel, long labor time, low efficiency, high cost and the like. Moreover, the floor groove in the container is prone to various oil stains, article fragments, biological liquids and the like, so that the water washing method cannot achieve complete removal. Figure 11 There are also some polishing equipment for polishing to achieve rust removal, such as patent No. CN208019984U discloses an automatic polishing equipment for refrigerated container floor, which comprises a base and a driving system, a polishing system and an electrical control system mounted on the base; the polishing system comprises a motor and a polishing shaft, the polishing 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 the driving synchronous pulley, the driving synchronous pulley is connected with the driven synchronous pulley of the polishing shaft through the double-sided synchronous belt for transmission; the synchronous pulley is sleeved on the polishing shaft, and a key is arranged between the synchronous pulley and the shaft.

[0005] However, the technology has the following technical problems:

[0006] (1) The technology drives the main synchronous pulley to rotate through the motor, and then drives the driven synchronous pulley to rotate through the transmission belt, and finally drives the polishing brush to polish. As can be seen, the polishing brush of the technology is synchronous, so the electrical control system can only control the polishing equipment to select a certain surface to be polished for polishing, and cannot realize simultaneous polishing of the bottom surface, side surface, upper surface and lower surface of the floor groove, which makes the floor groove take a long time to be completely polished and the polishing efficiency is low.

[0007]

[0008] ​And the polishing brush used in the technology is used for polishing, and only the side surface and part of the lower surface of the floor groove can be polished. The polishing brush is provided with a shaft, and after the polishing brush enters the floor groove, the end of the shaft will be against the bottom surface of the floor groove, and the polishing brush cannot contact 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 the side surface of the floor groove, so even if the polishing brush is aligned with the upper surface of the floor groove, the brush head cannot face the upper surface, and the upper surface of the floor groove cannot be polished or the polishing effect is poor. It can be seen that the polishing range of the technology is limited, and there are many dead angles during polishing, which is easy to miss positions.

[0009] (2) The polishing brush in the technology is fixed in position, and after long-term use, wear and tear will inevitably occur, which will cause the position of the brush head of the polishing brush to be different from the contact degree of the polishing surface of the floor groove, so that the polishing brush cannot be fully contacted with the floor groove, and the polishing is not complete. At this time, the polishing brush can only be replaced to ensure the polishing effect, which increases the cost.

[0010] (3) In the container floor groove, some foreign matters will inevitably remain, and if the foreign matters are encountered during the movement of the polishing equipment, the polishing equipment will be damaged, and the polishing effect of the polishing equipment will be affected. The technology does not consider the presence of foreign matters in the floor groove, and the detection of foreign matters in the floor groove cannot be realized.

[0011] (4) The width of the polishing brush in the technology is greater than the width of the floor groove, so that the polishing brush can be contacted with the side surface of the floor groove for polishing when entering the floor groove. Therefore, the polishing brush cannot directly enter the floor groove, and needs to be obliquely inserted into the floor groove before being connected with the shaft for polishing. When taking out, the polishing brush also needs to be disassembled and then taken out obliquely. The installation and disassembly consume a long time, resulting in low polishing efficiency. SUMMARY

[0012] In view of the above problems, the present application provides a floor groove polishing equipment and a working method, which can realize dead angle-free polishing and high polishing efficiency. Moreover, after long-term use, the polishing equipment can still ensure full contact with each surface of the floor groove.

[0029] After the adjustment is completed, the first polishing mechanism and the second polishing mechanism are controlled to work simultaneously;

[0030] The second reduction motor of the first polishing mechanism drives the gear in the gear box to rotate, and finally the polishing brush rotates to polish the upper surface, the side surface and the lower surface of the floor groove;

[0033] Further, in the moving process, whether there is foreign matter in the floor groove is detected by the front sensing arm of the front sensing device, when the front sensing arm touches the foreign matter, a travel switch is triggered, the travel switch feeds back parking information, and then the floor groove polishing device stops advancing.

[0034] Compared with the prior art, the present application has the advantages and positive effects that:

[0035] 1. This invention includes a grinding assembly, in which a first grinding mechanism and a second grinding mechanism work together to achieve grinding without dead angles. The first grinding mechanism drives the gears in the gearbox to rotate via a second reduction motor, which in turn rotates the grinding brushes. Multiple grinding brushes are spaced apart to grind the upper surface, lower surface, and sides of the floor groove. The second grinding mechanism drives the pulley in the belt drive assembly to rotate via the first reduction motor, which in turn rotates the disc brush, thus grinding the bottom surface of the floor groove. Furthermore, the oscillating drive unit oscillates the disc brush while it rotates, ensuring thorough grinding of the bottom surface of the floor groove.

[0036] The first and second grinding mechanisms of this invention each have independent transmission structures, allowing them to operate simultaneously. This means they can simultaneously grind the bottom, top, bottom, and sides of the floor groove, greatly improving grinding efficiency. It can clean various stains, oxide layers, debris, etc., providing powerful cleaning capabilities and high efficiency. The grinding equipment cleans without dead angles, achieving all-around brushing.

[0037] 2. This invention includes a grinding assembly lifting device. By raising and lowering the grinding assembly, the grinding brush of the first grinding mechanism and the disc brush of the second grinding mechanism can fully contact all surfaces of the floor groove, thus ensuring the grinding effect of the floor groove. After long-term use, the contact degree between the grinding brush and the disc brush and the floor groove can be adjusted by controlling the raising and lowering of the grinding assembly lifting device. Even after wear, it can still ensure that the grinding brush and the disc brush are fully in contact with all surfaces of the floor groove, thereby allowing the grinding brush and the disc brush to be used for a long time without frequent replacement, reducing costs.

[0038] The height of the second polishing mechanism can be finely adjusted by the height fine-tuning device, thereby adjusting the degree of contact between the disc brush and the bottom surface of the floor groove. This improves the accuracy of height adjustment, fully utilizes the polishing effect of the disc brush, and ensures that the disc brush is used in sufficient quantities, avoiding waste.

[0039] 3. The present invention is equipped with a front sensing device. The front sensing arm of the front sensing device detects whether there are foreign objects in the floor groove. When the front sensing arm touches the foreign object, it triggers the limit switch. The limit switch feeds back a stop information, thereby stopping the grinding equipment from moving forward. This can avoid damage to the grinding equipment and ensure the grinding effect of the grinding equipment.

[0040] 4、The polishing brush of the first polishing device in the application can directly enter the floor groove from above the floor groove, and after polishing is completed at a position, the polishing brush can be separated from the floor groove by lifting upward directly. Since the width of the disc brush is less than the slot width of the floor groove, the disc brush can directly enter the floor groove from the slot of the floor groove, so as to contact the bottom surface of the floor groove, and then the polishing of the bottom surface of the floor groove is realized through disc brush swinging and rotating, without repeated installation and disassembly, and the polishing efficiency is high.

[0041] 5、The floor groove polishing equipment in the application can polish and clean, and can solve various stains, sundries, surface oxides, surface scratches and the like. High-efficiency cleaning, simple equipment operation, high safety performance, clean dead angle and the like are realized. BRIEF DESCRIPTION OF DRAWINGS

Figure 2 ​As shown, the first geared motor 19 and the second geared motor 20 are housed within the first housing 107, which encloses and protects them. The belt drive assembly 105, the height fine-tuning device 104, and the limit switch 1031 of the front sensing device 103 are housed within the second housing 108, which also provides protection.

[0078] like Figure 3 As shown, the grinding assembly lifting device 3 includes a bracket 301. A lifting motor mounting bracket 308 is installed at the lower end of the bracket 301, and the lifting motor mounting bracket 308 is connected to the side of the electrical control compartment 2. A lifting motor 303 is installed on the lifting motor mounting bracket 308. The output end of the lifting motor 303 is connected to a first screw 304. A lifting block 307 is sleeved on the first screw 304. One end of the lifting block 307 is connected to one end of a tripod 306, and one end of the tripod 306 is connected to the grinding assembly 1. Lifting guide rails 302 are installed at both ends of the bracket 301, and guide blocks 305 are installed at both ends of the tripod 306. One end of the guide block 305 is located inside the lifting guide rail 302, and the guide block 305 slides within the lifting guide rail 302.

[0079] The lifting motor 303 drives the first screw 304 to rotate, thereby causing the lifting block 307 to move up and down. The lifting block 307 is fixedly connected to the tripod 306. The movement of the lifting block 307 drives the tripod 306 to move up and down. The tripod 306 is connected to the grinding assembly 1. Therefore, the up and down movement of the tripod 306 can drive the grinding assembly 1 to move up and down, thus realizing the height adjustment of the grinding assembly 1.

[0080] like Figure 10 As shown, when the sanding equipment is in the sanding position, the sanding assembly lifting device 3 is activated, ensuring that the first sanding mechanism 101 and the second sanding mechanism 102 of the sanding assembly 1 are in full contact with the floor groove, thus ensuring the sanding effect of the floor groove. Furthermore, when the sanding brush 24 and the disc brush 18 show wear, the height of the sanding assembly 1 can be lowered, allowing the sanding brush 24 and the disc brush 18 to again make full contact with the floor groove, thereby ensuring the sanding effect. A guide block 305 is provided on the tripod 306. During the lifting process, the guide block 305 slides within the lifting guide rail 302, thereby ensuring the stability of the lifting of the sanding assembly 1 and allowing the sanding brush 24 and the disc brush 18 to sand the floor groove in the accurate position.

[0081] like Figure 7As shown, one end of the belt transmission assembly 105 is provided with the height fine adjustment device 104, which includes a second mounting bracket 1047 connected with the first mounting plate 21, one end of the second mounting bracket 1047 is provided with a rotating handle 1041 connected with a rotating rod 1042 penetrating through the second mounting bracket 1047; both ends of the rotating rod 1042 are sleeved with a first bevel gear 1043, one end of the first bevel gear 1043 is engaged with a second bevel gear 1044, the second bevel gear 1044 is sleeved on a threaded rod 1045 arranged in a lifting column 1046 fixedly connected with a third mounting plate 1058.

[0082] In use, rotating the rotating handle 1041 makes the rotating rod 1042 rotate, and then drives the first bevel gear 1043 to rotate, the first bevel gear 1043 drives the second bevel gear 1044 to rotate, the second bevel gear 1044 drives the threaded rod 1045 to rotate, the inner wall surface of the lifting column 1046 is provided with an internal thread, the rotation of the threaded rod 1045 makes the lifting column 1046 move up and down, since the lifting column 1046 is fixedly connected with the third mounting plate 1058, the second polishing mechanism 102 can be driven to move up and down, and the height of the disc brush 18 can be finely adjusted. The linear slide rail 1063 assists in lifting during the lifting of the second polishing device 102, ensuring the stability during the lifting.

[0083] The disc brush 18 is a consumable part, which is consumed during use, resulting in a decrease in the diameter of the disc brush 18. Therefore, the height fine adjustment device 104 is used to adjust the entire polishing device to move downward, so as not to affect the cooperation of other structures, and the disc brush 18 can be fully utilized, reducing the cost.

[0084] After long-term polishing, the wear of the disc brush 18 and the polishing brush 24 is inconsistent, so the height of the disc brush needs to be adjusted separately. The height of the disc brush 18 and the polishing brush 24 is adjusted by the polishing assembly lifting device 3, and then the height of the disc brush 18 is adjusted more finely according to the wear degree of the disc brush 18, so that the disc brush 18 can still fully contact the polishing surface after wear. Even if the wear of the disc brush 18 and the polishing brush 24 is inconsistent, it can be ensured that the disc brush 18 and the polishing brush 24 fully contact the polishing surface.

[0085] As Figure 6As shown, the other end of the belt drive assembly 105 is provided with a front sensing device 103, which includes a mounting rod 1033 penetrating through a first mounting frame 1032 fixedly connected with the third mounting plate 1058, and the upper end of the first mounting frame 1032 is provided with a travel switch 1031; the front sensing arm 1034 is sleeved on the mounting rod 1033 and located at the front part of the polishing brush 24.

[0092] The walking system is used to move the entire device, and is driven by a drive motor. One end of the lower part of the electrical control compartment 2 is equipped with a caster wheel 5, and the other end is equipped with a drive wheel 7; limit wheels 6 are installed on the inner side of the caster wheel 5 and the drive wheel 7.

[0093] The walking system includes a drive motor, chain, drive wheel 7, front guide wheel, swivel wheels 5, and rear guide wheel. The drive motor drives the chain, causing the drive wheel 7 to rotate and move. The two swivel wheels 5 follow the chain, forming a four-wheel supported front-drive walking system. The wheel width of the drive wheel 7 and swivel wheels 5 is greater than the width of the container floor groove, meaning it moves on the bottom of the container.

[0094] A front limit wheel 6 and a rear limit wheel 6 are installed at the middle positions of the front and rear of the chassis frame. The width of the front and rear limit wheels 6 is adapted to the width of the groove.

[0103] After the adjustment, the first polishing mechanism 101 and the second polishing mechanism 102 are controlled to work simultaneously; the second reduction motor 20 of the first polishing mechanism 101 drives the gear in the gear box 23 to rotate, finally making the polishing brush 24 rotate to polish the upper surface, side surface and lower surface of the floor groove; the rotating drive unit 109 of the second polishing mechanism 102 drives the disc brush to rotate; at the same time, the swing motor 1061 of the swing drive unit 106 drives the cam 1062 to rotate, the cam 1062 drives the swing arm 1064 to swing, further drives the linkage rod 1065 to swing, then the linkage rod 1065 drives the connecting rod 1066 to swing, the connecting rod 1066 drives the rotating shaft 1068 to swing, finally the rotating shaft 1068 drives the disc brush 18 to swing along the axial direction of the disc brush 18; the disc brush 18 rotates while swinging, so that the disc brush 18 fully polishes the bottom surface of the floor groove;
