Technical Field

[0002] Scaffolding is a temporary construction tool set up at the construction site for workers to operate and solve vertical and horizontal transportation.

[0003] The scaffolding cross bars need to be galvanized during production. After stacking several scaffolding cross bars together, these stacked scaffolding cross bars need to be flipped into a vertical state to be tied to the hanger of the galvanizing equipment. A scaffolding cross bar galvanizing flipping mechanism is needed to flip the scaffolding cross bars. For example, the Chinese patent application number 202320386092.6 discloses a "galvanized flipping mechanism for a disc-shaped scaffolding cross bar, including a base, a frame structure, a middle position of the top surface of the base is rotatably connected to a support member, and the support member adopts an L-shaped structure, including a vertically arranged first support member. The first support part and the second support part are rotatably connected to the base at the intersection of the first support part and the second support part, the first support part is hinged to one end of the linear telescopic drive member, and the other end of the linear telescopic drive member is hinged to the end of the bottom of the base, and also includes a plurality of cross bar tooling, and the first support part and the second support part can both hold a plurality of cross bar tooling." However, the above-mentioned scaffolding cross bar galvanized flipping mechanism lacks a fixing measure for the scaffolding cross bar when flipping the scaffolding cross bar, and the scaffolding cross bar is prone to scattering and falling when flipping. Therefore, in order to solve such problems, a scaffolding cross bar galvanized flipping mechanism is proposed. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-6A galvanized flip mechanism for a scaffolding crossbar comprises a base plate 1, a first fixing plate 6 and a second fixing plate 7 are rotatably mounted on the base plate 1, two connecting plates 8 are mounted between the first fixing plate 6 and the second fixing plate 7, and a clamping mechanism is provided between the two connecting plates 8;

[0027] The clamping mechanism includes a bidirectional screw rod 14 with positive and negative threads rotatably arranged on the side of the second fixed plate 7. The two sections of the bidirectional screw rod 14 with positive and negative threads have opposite thread rotation directions and are both sleeved with internal thread blocks 15. A strip opening 11 is provided on the side of the second fixed plate 7. The internal thread block 15 passes through the strip opening 11 and is connected to the clamping plate 9. The clamping plate 9 is located between the first fixed plate 6 and the second fixed plate 7. A limiting component for limiting the internal thread block 15 is provided on the side of the second fixed plate 7.

[0028] As a technical optimization solution of the present invention, the limiting assembly includes a mounting plate 12 installed on the side of the second fixed plate 7, a second motor 13 is installed on the side of the mounting plate 12, the output shaft of the second motor 13 passes through the mounting plate 12 and is connected to the forward and reverse bidirectional screw rod 14, a first slide rod 18 is installed on the side of the mounting plate 12, a first sleeve 17 is installed at the bottom of the internal thread block 15, the first sleeve 17 is slidably sleeved on the first slide rod 18, and the cooperation of the first sleeve 17 and the first slide rod 18 can provide a limiting effect for the internal thread block 15, so that the internal thread block 15 can make lateral movement on the forward and reverse bidirectional screw rod 14.

[0029] As a technical optimization solution of the present invention, a fixing block 16 is installed on the side of the internal thread block 15 close to the clamping plate 9. The fixing block 16 passes through the strip opening 11 and is connected to the clamping plate 9. The strip opening 11 can facilitate the connection between the internal thread block 15 and the clamping plate 9.

[0030] As a technical optimization solution of the present invention, an installation groove 21 is opened on the side of the clamping plate 9, and a rubber pad 10 is installed in the installation groove 21. The installation groove 21 can provide a mounting plane for the rubber pad 10, facilitating the connection between the rubber pad 10 and the clamping plate 9.

[0031] As a technical optimization solution of the present invention, a number of second sliding sleeves 19 are installed at the bottom of the two clamping plates 9, and a second sliding rod 20 is slidably installed in each group of corresponding second sliding sleeves 19 at the bottom of the two clamping plates 9, and a limiting block is provided at both ends of the second sliding rod 20.

[0032] As a technical optimization solution of the present invention, a first support plate 2 is installed on the top of the base plate 1, a first motor 4 is installed on the side of the first support plate 2, and the output shaft of the first motor 4 passes through the first support plate 2 and is connected to the first fixed plate 6.

[0033] As a technical optimization solution of the present invention, a second support plate 3 is installed on the top of the base plate 1, and the second support plate 3 is symmetrical to the first support plate 2. The first fixed plate 6 and the second fixed plate 7 are located between the first support plate 2 and the second support plate 3. The second support plate 3 is rotatably connected to the side close to the second fixed plate 7 with a connecting shaft 5, and the end of the connecting shaft 5 is connected to the second fixed plate 7. The connecting shaft 5 can facilitate the connection between the second fixed plate 7 and the second support plate 3.

[0034] As a technical optimization solution of the present invention, a bearing is installed on the side of the second support plate 3 close to the second fixed plate 7, and the connecting shaft 5 is installed on the inner ring of the bearing. The bearing can facilitate the rotational connection between the connecting shaft 5 and the second support plate 3.

[0035] When the present invention is in use, first, the first motor 4 is started, and the output shaft of the first motor 4 drives the first fixing plate 6 and the second fixing plate 7 to rotate, thereby rotating the two clamping plates 9, and rotating the two clamping plates 9 to an upper and lower state.

[0036] At this time, the scaffolding cross bars that need to be galvanized are placed horizontally on the clamping plate 9 located below, and the ends of the scaffolding cross bars are made to contact the second slide bars 20. Several second slide bars 20 are used to block the ends of the scaffolding cross bars, and the scaffolding cross bars that need to be galvanized are placed horizontally in rows on the clamping plate 9 located below.

[0037] When the number of scaffolding cross bars placed on the clamping plate 9 below reaches a predetermined number, the second motor 13 is started, and the output shaft of the second motor 13 drives the forward and reverse bidirectional screw rod 14 to rotate. The rotation of the forward and reverse bidirectional screw rod 14 causes the two internal thread blocks 15 to move closer to each other on the forward and reverse bidirectional screw rod 14, thereby causing the two clamping plates 9 to move closer to each other. By using the two clamping plates 9 to move closer to each other, the two clamping plates 9 can clamp and fix the scaffolding cross bars between the two clamping plates 9, thereby clamping and fixing the scaffolding cross bars between the two clamping plates 9.

[0038] At this time, the first motor 4 is started again to rotate the two clamping plates 9, and the two clamping plates 9 can be rotated to a left and a right state, so that the two clamping plates 9 can drive the scaffolding cross bar clamped and fixed between the two clamping plates 9 to rotate during rotation, and then the scaffolding cross bar clamped and fixed between the two clamping plates 9 can be rotated to a vertical state, thereby completing the flipping of the scaffolding cross bar and flipping the scaffolding cross bar clamped and fixed between the two clamping plates 9 to a vertical state. When the scaffolding cross bar is flipped to the vertical state, the scaffolding cross bar between the two clamping plates 9 is clamped and fixed by the two clamping plates 9, and the ends of the scaffolding cross bar are limited by several second sliding bars 20, which can make the scaffolding cross bar between the two clamping plates 9 more stable when flipping, avoid the scaffolding cross bar from scattering and falling when flipping, and improve the stability of the scaffolding cross bar when flipping.

[0039] In addition, the rubber pad 10 between the two clamping plates 9 can provide a flexible clamping for the scaffolding cross bar, avoiding the rigid clamping of the scaffolding cross bar by the two clamping plates 9, which may cause deformation and damage to the scaffolding cross bar, thereby improving the protection of the scaffolding cross bar. In addition, the softness of the rubber pad 10 can also make the contact between the rubber pad 10 and the scaffolding cross bar more component, and the friction between the scaffolding cross bar in contact with the rubber pad 10 and the rubber pad 10 is also stronger, which can also increase the clamping stability of the clamping plate 9 on the scaffolding cross bar.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
