Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, and in particular to a street lamp pole surface cleaning device for street lamp production. Background Art

[0002] The length and diameter of street light poles vary depending on their usage. Street lights installed in parks or courtyards are all low-height street lights. The common production process of street light poles is cutting → bending → welding → repairing and grinding → shaping → flushing → installing the base plate → welding the bottom flange and rib plate → punching → galvanizing → spraying. Usually the rusted parts are concentrated at the welds. After the street light poles are rolled and welded with blackboard (steel plate), they must be polished and cleaned before galvanizing. Because the surface of the lamp pole after galvanizing is very hard, if the spatter generated during the welding process is not cleaned before galvanizing, it is difficult to clean it after galvanizing.

[0003] For example, the publication number is CN117047632A, and the name is a street lamp pole surface cleaning device for street lamp production. The problem that the invention aims to solve is that the commonly used street lamp pole surface grinding and cleaning methods mostly adopt manual methods to grind and clean the welding positions. Because the street lamp poles are mostly round in shape, it is not convenient to grind and clean them. Because the street lamp poles are directly placed on the external clamping device during surface grinding, the iron filings generated during grinding will fall to the ground or float in the air. At the same time, some iron filings will fall on the surface of the street lamp pole again. When in use, the grinding and cleaning efficiency of the street lamp pole surface is low, and it will also affect the surrounding environment and the health of the staff.

[0004] When the above invention is used to clean street lamp poles, it is difficult to ensure the consistency of the polishing effect due to the different diameters of the street lamps, and excessive pressure can easily lead to over-polishing. Therefore, it is necessary to continuously adjust the polishing force according to the diameter of the lamp post. Therefore, the present application provides a street lamp pole surface cleaning device for street lamp production to meet the needs. Summary of the invention

[0017] In summary, the technical effects and advantages of the present invention are as follows:

[0018] 1. The coordinated use of the sliding mechanism and the positioning mechanism in the present invention, plus the height adjustment function of the supporting mechanism, enables the equipment to adapt to lamp posts of different diameters, allowing the sanding rope to be in close contact with the surface for polishing on lamp posts of various sizes; and the tensioning mechanism can automatically adjust the tension of the sanding rope according to the change in the diameter of the lamp post, ensuring that the sanding rope maintains sufficient pressure when contacting the surface of the lamp post, thereby ensuring the consistency and quality of the polishing effect, and at the same time, avoiding damage to the surface of the lamp post due to excessive pressure, thereby extending the service life of the lamp post; the sanding rope moves in a belt transmission manner, polishing the surface of the lamp post in both positive and negative directions, and bidirectional polishing can improve the polishing efficiency, while ensuring that the polishing of the lamp post surface is uniform, thereby improving the overall quality of the surface treatment.

[0019] 2. The sliding design between the semi-annular cylinder and the mounting shell and the use of the first spring in the present invention enable the device to adapt to lamp posts of different diameters. When the diameter of the lamp post increases or decreases, the semi-annular cylinder will slide accordingly in the direction away from or close to the lamp post, thereby adjusting the tension and the number of windings of the sanding rope to ensure that the sanding rope can always be close to the surface of the lamp post no matter how the diameter of the lamp post changes; the function of the first spring is to automatically adjust the distance between the semi-annular cylinder and the lamp post, and then automatically adjust the tension of the sanding rope. The automatic adjustment mechanism can ensure that when the diameter of the lamp post changes, the sanding rope can still maintain an appropriate tension state, neither too loose nor too tight, thereby maintaining the consistency of the polishing effect; the design of the limit block and the limit rod in the circular hole inside the mounting slide prevents the semi-annular cylinder from completely detaching from the mounting shell during the sliding process, thereby ensuring the stability and safety of the device, while also limiting the compression range of the first spring to prevent the spring from being over-compressed and failing.

[0020] 3. The design of the second convex strip and the first convex strip in the present invention increases the friction force on the surface of the recessed wheel and the arc wheel. The recessed wheel is driven to rotate by a driving motor, and then the arc wheel is driven to rotate by gear transmission. The use of the cone wheel and the shrinking wheel not only guides the correct winding of the sanding rope, but also can automatically adjust the position of the shrinking wheel according to the tension of the sanding rope through the sliding mechanism of the shrinking wheel, thereby maintaining the appropriate tension of the sanding rope and avoiding polishing quality problems caused by insufficient or excessive tension. The specific design of the cone wheel and the interaction of the sanding rope with the cone wheel during the transmission process can effectively prevent the sanding rope from falling off the cone wheel surface, thereby ensuring the continuity and safety of the sanding process.

[0021] 4. The combined design of the ring plate and the semi-ring cylinder in the present invention can adapt to lamp posts of different diameters. When the diameter of the lamp post changes, the ring plate can slide on the second slide rail to form a complete circle with the semi-ring cylinder, ensuring that the sanding rope can cling to the surface of the lamp post and wrap around it for a circle. The third spring continuously applies thrust to the push block. When the diameter of the lamp post changes, the ring plate and the push block can slide on the outer surface of the second slide rail and the semi-arc ring, automatically adjusting the tension of the sanding rope to ensure the consistency of the polishing effect.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1, Reference Figures 1 to 15 A street lamp pole surface cleaning device for street lamp production is shown, comprising a lamp post 1 and a positioning mechanism 2, a sliding mechanism 3 is slidably mounted on the outer surface of the positioning mechanism 2, a supporting mechanism 4 for supporting the position height of the positioning mechanism 2 and the sliding mechanism 3 is arranged in the middle of one side of the positioning mechanism 2 and the sliding mechanism 3, a rope winding mechanism 6 is arranged on the outer surface of the positioning mechanism 2, a tensioning mechanism 7 is slidably mounted on the outer surface of the sliding mechanism 3, a sanding rope 5 is wound together inside the tensioning mechanism 7 and the rope winding mechanism 6, and the sanding rope 5 is wound around the outer surface of the lamp post 1;

[0041] It is worth noting that the lamp post 1 is first suspended at the position to be cleaned, and then the positioning mechanism 2 and the sliding mechanism 3 are placed on the surface of the lamp post 1. The height of the supporting mechanism 4 is adjusted according to the diameter of the lamp post 1, so that the lamp post 1 is located at the central axis of the positioning mechanism 2 and the sliding mechanism 3. Then, the user pushes the sliding mechanism 3 to slide on the lamp post 1, and then pushes the tensioning mechanism 7 to slide on the sliding mechanism 3. When the tensioning mechanism 7 slides, the sanding rope 5 is pulled and tightly wound on the surface of the lamp post 1, and the winding shape of the sanding rope 5 is Fig. 9 In the shape shown, when the sanding rope 5 is stretched and fits tightly against the outer surface of the lamp post 1, the rope winding mechanism 6 drives the sanding rope 5 to transmit, and the movement of the sanding rope 5 is in the form of a belt transmission, so the sanding rope 5 wound on the surface of the lamp post 1 is polished in both positive and negative grinding directions to the surface of the lamp post 1;

[0042] When the sanding rope 5 continues to polish, the user needs to slowly push the supporting mechanism 4 to drive the sliding mechanism 3 and the positioning mechanism 2 to move. As the positioning mechanism 2 and the sliding mechanism 3 move, the rope winding mechanism 6 and the tensioning mechanism 7 will move, and the sanding rope 5 will continue to polish and clean the surface of the lamp post 1 along the direction pushed by the user. Because the overall diameter of the lamp post 1 is not the same, the tensioning mechanism 7 and the sliding mechanism 3 can adjust the tension of the sanding rope 5 according to the diameter of the lamp post 1, so that the sanding rope 5 can be tightly attached to the surface of the lamp post 1 for polishing and cleaning. The setting of the sliding mechanism 3 and the positioning mechanism 2 can make the sanding rope 5 suitable for lamp posts 1 of different sizes, thereby improving the flexibility and applicability of the equipment.

[0043] The tensioning mechanism 7 can automatically adjust the tension of the sanding rope 5 according to the diameter change of the lamp post 1, ensuring that the sanding rope always maintains sufficient pressure when contacting the surface of the lamp post to ensure the cleaning effect, while also avoiding damage to the surface of the lamp post 1 caused by excessive pressure.

[0044] The coordinated use of the sliding mechanism 3 and the positioning mechanism 2, together with the height adjustment function of the supporting mechanism 4, enables the device to adapt to lamp posts 1 of different diameters, allowing the sanding rope 5 to be close to the surface for polishing on lamp posts of various sizes.

[0045] Moreover, the tensioning mechanism 7 can automatically adjust the tension of the sanding rope 5 according to the change of the diameter of the lamp post 1, ensuring that the sanding rope maintains sufficient pressure when contacting the surface of the lamp post 1, thereby ensuring the consistency and quality of the polishing effect. At the same time, it avoids damage to the surface of the lamp post 1 due to excessive pressure, and prolongs the service life of the lamp post 1.

[0046] The sanding rope 5 moves in a belt transmission manner to polish the surface of the lamp post 1 in both positive and negative directions. Bidirectional polishing can improve the polishing efficiency, while ensuring that the lamp post surface is polished evenly and improving the overall quality of the surface treatment.

[0047] The supporting mechanism 4 includes a fixed block 41, a first connecting block 42 is slidably installed inside the fixed block 41, an inner groove 45 is opened inside the first connecting block 42, a positioning bolt 46 is arranged inside the fixed block 41, the positioning bolt 46 passes through the inner groove 45 and is used to fix the position of the first connecting block 42, a base frame 43 is arranged at the bottom of the first connecting block 42, an auxiliary wheel 44 is rotatably installed inside the base frame 43, and the two fixed blocks 41 are fixedly connected to the mounting shell 21 and the semi-annular cylinder 31 respectively.

[0048] It is worth noting that, when in use, the support mechanism 4 is adjusted according to the diameter of the lamp post 1 so that the lamp post 1 is located at the central axis of the positioning mechanism 2 and the sliding mechanism 3, and the first connecting block 42 is pushed to slide inside the fixing block 41. The distance between the lamp post 1 and the positioning mechanism 2 is adjusted by adjusting the height of the first connecting block 42. After the sliding height of the first connecting block 42 is adjusted, the positioning bolt 46 is rotated to fix the position of the first connecting block 42.

[0049] When the sanding rope 5 is wound around the surface of the lamp post 1 for polishing and cleaning, the first connecting block 42 is pushed through the bottom frame 43 to drive the auxiliary wheel 44 to rotate on the surface of the lamp post 1. The setting of the supporting mechanism 4 can prevent the sanding rope 5 from contacting the inner wall of the positioning mechanism 2 and the sliding mechanism 3 when the sanding rope 5 is polishing and cleaning the surface of the lamp post 1. The shape of the auxiliary wheel 44 is Fig.15 This ensures that the auxiliary wheel 44 will not fall off when the lamp post 1 rotates.

[0050] Among them, the use of the positioning bolt 46 ensures that the first connecting block 42 can be firmly fixed after being adjusted to a suitable height, preventing position displacement due to vibration or external force during the polishing process, thereby maintaining the stability of the device operation and the accuracy of polishing. The design of the auxiliary wheel 44 can prevent the sanding rope 5 from directly contacting the inner walls of the positioning mechanism 2 and the sliding mechanism 3 during the transmission process, reducing unnecessary friction and wear, and maintaining the tension and smooth movement of the sanding rope 5.

[0051] The positioning mechanism 2 includes a mounting shell 21, a plurality of first slide rails 22 are arranged on the outer surface of the mounting shell 21, and a slide groove 23 is opened at the bottom of the first slide rail 22, a limiting rod 25 is arranged on one side of the mounting shell 21 and between every two first slide rails 22, and a first spring 24 is sleeved on the outer surface of the limiting rod 25, and the first mounting block 62 is fixedly connected to the mounting shell 21.

[0052] The sliding mechanism 3 includes a semi-annular cylinder 31, and the inner wall of the semi-annular cylinder 31 is provided with a plurality of mounting grooves 32 corresponding to the positions of the first slide rail 22. The semi-annular cylinder 31 is slidably mounted on the outer surface of the first slide rail 22 through the mounting grooves 32, and a limit block is arranged inside the mounting groove 32 and is located inside the groove 23 to prevent the semi-annular cylinder 31 from being separated from the surface of the mounting shell 21.

[0053] It is worth noting that the semi-annular cylinder 31 is pushed to slide on the surface of the mounting shell 21, and the first slide rail 22 slides inside the mounting slide groove 32. The limit block provided inside the mounting slide groove 32 is used to prevent the semi-annular cylinder 31 from detaching from the surface of the mounting shell 21, and the first spring 24 is provided to resist the semi-annular cylinder 31. When the sanding rope 5 is wound around the lamp post 1 with a larger diameter, the number of turns of the sanding rope 5 around the lamp post 1 can be adjusted by adjusting the sliding distance between the semi-annular cylinder 31 and the mounting shell 21, and the length setting of the sanding rope 5 can ensure that it is wound around the lamp post 1 for one turn.

[0054] The limit rod 25 is located inside the circular hole 33 and can limit the first spring 24, and the first spring 24 continuously resists the semi-annular cylinder 31 and applies thrust to the semi-annular cylinder 31. When the sanding rope 5 is polished on the surface of the lamp post 1, as the diameter of the lamp post 1 becomes larger or smaller, the first spring 24 can push the semi-annular cylinder 31 or the semi-annular cylinder 31 squeezes the first spring 24 to adjust the sliding distance between the semi-annular cylinder 31 and the mounting shell 21, thereby adjusting the tension of the sanding rope 5 wrapped around the surface of the lamp post 1.

[0055] Among them, the sliding design between the semi-annular cylinder 31 and the mounting shell 21, and the use of the first spring 24, enable the device to adapt to lamp posts 1 of different diameters. When the diameter of the lamp post increases or decreases, the semi-annular cylinder 31 will slide accordingly in the direction away from or close to the lamp post 1, thereby adjusting the tension and number of windings of the sanding rope 5, ensuring that the sanding rope 5 can always be close to the surface of the lamp post regardless of how the diameter of the lamp post changes.

[0056] The function of the first spring 24 is to automatically adjust the distance between the semi-annular tube 31 and the lamp post 1, and then automatically adjust the tension of the sanding rope 5. The automatic adjustment mechanism can ensure that when the diameter of the lamp post 1 changes, the sanding rope 5 can still maintain an appropriate tension state, neither too loose nor too tight, so as to maintain the consistency of the polishing effect.

[0057] The design of the limit block inside the mounting groove 32 and the limit rod 25 in the circular hole 33 prevents the semi-annular cylinder 31 from completely detaching from the mounting shell 21 during the sliding process, thereby ensuring the stability and safety of the device, and also limits the compression range of the first spring 24, thereby preventing the spring from being over-compressed and failing.

[0058] Example 2, Reference Figures 6 to 8 The rope winding mechanism 6 shown includes a first mounting block 62, a driving motor 61 is arranged at the bottom of the first mounting block 62, the output end of the driving motor 61 passes through the first mounting block 62 and is fixedly installed with a recessed wheel 613, a second gear 612 is arranged at the bottom of the recessed wheel 613, and a plurality of second convex strips 614 distributed in a ring array are fixedly installed on the outer surface of the recessed wheel 613.

[0059] A second connecting block 66 is fixedly mounted on one side of the first mounting block 62, a shaft 68 is disposed at the upper end of the second connecting block 66, an arc wheel 69 is rotatably mounted on the outer surface of the shaft 68, a plurality of first convex strips 611 distributed at equal intervals are disposed on the outer surface of the arc wheel 69, a first gear 67 is disposed at the bottom of the arc wheel 69, and the first gear 67 is meshed with the second gear 612;

[0060] A support rod 64 is provided on one side of the upper part of the first mounting block 62, and a cone wheel 63 is provided on the outer surface of the support rod 64. The sanding rope 5 is wound around the outer surface of the recessed wheel 613 and the cone wheel 63. A second mounting block 615 is provided on one side of the upper end of the first mounting block 62, and a slider 618 is slidably installed inside the second mounting block 615. A second spring 617 is provided on one side of the slider 618, and the second spring 617 is located inside the second mounting block 615. A connecting rod 616 is provided on the upper end of the slider 618, and a retracting wheel 65 for adjusting the tension of the sanding rope 5 is rotatably installed on the outer surface of the connecting rod 616.

[0061] It is worth noting that, when in use, the driving motor 61 drives the recessed wheel 613 to rotate through the output shaft, and the sanding rope 5 is located between the arc wheel 69 and the recessed wheel 613. The second convex strip 614 and the first convex strip 611 are used to increase the friction between the surfaces of the recessed wheel 613 and the arc wheel 69. When the recessed wheel 613 rotates, the second gear 612 is driven to rotate, the second gear 612 drives the first gear 67 to rotate, and the first gear 67 drives the arc wheel 69 to rotate, and the sanding rope 5 is clamped between the arc wheel 69 and the recessed wheel 613, and the rotating sanding rope 5 is wound around the surface of the contraction wheel 65 and then bypasses the surface of the cone wheel 63;

[0062] After the sanding rope 5 is wound around the outer surface of the contraction wheel 65, the sanding rope 5 is prevented from being separated from the surface of the cone wheel 63 during transmission. The sanding rope 5 drives the contraction wheel 65 to rotate on the outer surface of the connecting rod 616, and the connecting rod 616 is driven by the tightening force of the sanding rope 5 to drive the slider 618 to slide inside the second mounting block 615. When the slider 618 slides, it squeezes the second spring 617 to contract.

[0063] Among them, the design of the second convex strip 614 and the first convex strip 611 increases the friction force on the surface of the recessed wheel 613 and the arc wheel 69. The recessed wheel 613 is driven to rotate by the driving motor 61, and then the arc wheel 69 is driven to rotate by the gear transmission. The use of the cone wheel 63 and the shrinking wheel 65 not only guides the sanding rope 5 to be wound correctly, but also through the sliding mechanism of the shrinking wheel 65, the position of the shrinking wheel 65 can be automatically adjusted according to the tension of the sanding rope 5, thereby maintaining the appropriate tension of the sanding rope 5 and avoiding polishing quality problems caused by insufficient or excessive tension.

[0064] The specific design of the cone wheel 63 and the interaction between the sanding rope 5 and the cone wheel 63 during the transmission process can effectively prevent the sanding rope 5 from falling off the surface of the cone wheel 63, thereby ensuring the continuity and safety of the sanding process.

[0065] Embodiment 3: The user can also place the sanding rope 5 between the retracting wheel 65 and the cone wheel 63, and set the second spring 617 as a retracting spring. When the sanding rope 5 is transmitted, the retracting wheel 65 will also rotate outside the connecting rod 616, and the set second spring 617 will retract and pull the slider 618 to slide inside the second mounting block 615, so that the retracting wheel 65 squeezes the sanding rope 5 to prevent the sanding rope 5 from detaching from the surface of the cone wheel 63 during transmission.

[0066] Example 4, Reference Figure 12 to Figure 14 The tensioning mechanism 7 shown includes a ring plate 71, which is slidably mounted on the outer surface of the second slide rail 36. A push block 72 is provided on one side of the ring plate 71, and the push block 72 is slidably mounted on the outer surface of the semi-arc ring 34. A limit block is provided inside the ring plate 71 to prevent the ring plate 71 from falling off the surface of the second slide rail 36.

[0067] A circular hole 33 corresponding to the position of the limiting rod 25 is opened on one side of the semi-annular cylinder 31, a semi-arc ring 34 is arranged on one side of the outer surface of the semi-annular cylinder 31, and a third spring 35 is sleeved on the outer surface of the semi-arc ring 34, and a second slide rail 36 is arranged on one side of the outer surface of the semi-annular cylinder 31.

[0068] It is worth mentioning that the ring plate 71 slides outside the second slide rail 36, and the push block 72 slides on the outer surface of the semi-arc ring 34, and the third spring 35 continuously applies thrust to the push block 72, and the ring plate 71 will drive the third connecting block 73 to move when it slides. Because the ring plate 71 and the semi-annular cylinder 31 are both semicircular in shape, when the ring plate 71 slides, it can form a complete circle in combination with the semi-annular cylinder 31. When the sanding rope 5 is polished and cleaned on the surface of the lamp post 1, as the diameter of the lamp post 1 changes, the ring plate 71 and the push block 72 can slide on the outer surface of the second slide rail 36 and the semi-arc ring 34 to adjust the tension of the sanding rope 5.

[0069] A third connecting block 73 is provided on one side of the ring plate 71, and two inclined rods 77 are rotatably installed inside the third connecting block 73. The outer surfaces of the two inclined rods 77 are provided with shaft sleeves 78, and the outer surfaces of the two shaft sleeves 78 are sleeved with arc cone wheels 74. Two arc grooves 75 are formed at the upper end of the third connecting block 73, and the outer surfaces of the two inclined rods 77 are provided with limiting blocks 76. The two limiting blocks 76 are slidably installed inside the arc grooves 75, and the bottom of the limiting blocks 76 is provided with bolts for limiting the sliding position of the limiting blocks 76.

[0070] During polishing and cleaning, the sanding rope 5 is wound around the surfaces of the two arc cone wheels 74, and the user can adjust the angle of the inclined rod 77 by sliding the limiting block 76 inside the arc groove 75. By adjusting the angle and distance of the two inclined rods 77, the sanding rope 5 can be closely attached to the surface of the lamp post 1, and then the position of the limiting block 76 is fixed by bolts. The shape of the arc cone wheel 74 is designed to be Fig.12 The shape shown can ensure that the sanding rope 5 will not fall off when it is wound around the surface of the arc cone wheel 74, and when the sanding rope 5 is driven, the arc cone wheel 74 drives the shaft sleeve 78 to rotate.

[0071] Among them, the combined design of the ring plate 71 and the semi-annular cylinder 31 can adapt to lamp posts 1 of different diameters. When the diameter of the lamp post changes, the ring plate 71 can slide on the second slide rail 36 to form a complete circle with the semi-annular cylinder 31, ensuring that the sanding rope 5 can be close to the surface of the lamp post and wrap around it for a circle. The third spring 35 continuously applies thrust to the push block 72. When the diameter of the lamp post 1 changes, the ring plate 71 and the push block 72 can slide on the outer surface of the second slide rail 36 and the semi-arc ring 34, automatically adjusting the tension of the sanding rope 5 to ensure the consistency of the polishing effect.
