Detailed Implementation

[0017] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] like Figure 1 As shown, the lifting base structure of this embodiment includes: a guide unit 100 and a support unit 200; multiple sets of guide units 100 are provided, and the multiple sets of guide units 100 are arranged at intervals along the circumference. Each guide unit 100 includes a first guide bracket 110 and a second guide bracket 120. The first guide bracket 110 includes a first guide component and a gearbox component 1111. The first guide component is provided at the upper end of the gearbox component 1111, and a second guide component is provided at the lower end of the second guide bracket 120. The gearbox component 1111 is welded to the second guide bracket 120 from top to bottom. Multiple sets of support units 200 are provided, and each set of support units 200 is provided between two adjacent sets of guide units 100. The two sides of the support unit 200 are respectively connected to the two sets of guide units 100.

[0019] By decomposing the lifting base structure into a guide unit 100 and a support unit 200, and further subdividing the guide unit 100 into a first guide bracket 110 and a second guide bracket 120, the lifting base structure is assembled into multiple components, which facilitates manufacturing. Before assembly, the gearbox component 1111 and the first guide component are assembled together. At the same time, the second guide component is assembled onto the second guide bracket 120, reducing assembly difficulty. Then, the second guide bracket 120 is hoisted and fixed in place. The gearbox component 1111 is then welded to the upper end of the second guide bracket 120, completing the initial installation of the guide unit 100. Then, each guide unit 100 is installed circumferentially. The support unit 200 is then placed between two adjacent guide units 100, and then the units are closed. Finally, the guide units 100 and the support units 200 are welded together to complete the installation of the lifting base structure. This method simplifies construction, reduces construction difficulty, and improves construction efficiency.

[0020] Understandably, referring to Figure 2 and Figure 3 The gearbox component 1111 includes a front panel 1114 and a rear panel 1115. A first support assembly is provided between the front panel 1114 and the rear panel 1115. The first support assembly is connected to both the front panel 1114 and the rear panel 1115 to form the gearbox component 1111. This structural design enhances the stability of the gearbox component 1111 and effectively supports the load-bearing capacity of the gearbox. The addition of the support assembly makes the installation and connection of the gearbox component 1111 more secure, avoiding safety hazards caused by loosening or instability of components during lifting. By supporting the front panel 1114 and the rear panel 1115 through the support assembly, the support members distributed between the front panel 1114 and the rear panel 1115 can effectively enhance the gearbox's resistance to compression and deformation, improve the rigidity of the overall structure, and evenly distribute the load, thereby enhancing the overall load-bearing capacity. In addition, the support component is welded between the front panel 1114 and the rear panel 1115. The support component welds the front panel 1114 and the rear panel 1115 together to form the gearbox component 1111. The structure is simple, easy to build, reduces the construction difficulty, improves the construction efficiency, and the reduced difficulty makes it easier to reduce the construction cost.

[0021] Specifically, it can be understood that, referring to Figure 3The first support assembly includes multiple first partitions 1117 and two side plates 1116. The first partitions 1117 are arranged along the width direction of the rear panel 1115. The multiple first partitions 1117 are spaced apart along the length direction of the gearbox component 1111. A second partition 1118 is arranged between two adjacent first partitions 1117. The second partition 1118 and the side plates 1116 are both arranged along the length direction of the rear panel 1115. The two ends of the second partition 1118 are respectively connected to the two first partitions 1117. The two side plates 1116 are respectively arranged at the two ends of the first partitions 1117. The side plates 1116 are simultaneously connected to the front panel 1114, the rear panel 1115, and the multiple first partitions 1117. In this embodiment, the first support assembly of the gearbox component 1111 includes multiple first partitions 1117 and two side plates 1116. The support assembly is formed by combining these partitions and side plates 1116, with the partitions spaced apart along the width and length directions of the gearbox. During assembly, the multiple first partitions 1117 are first welded to the rear panel 1115 at intervals along its length. Then, second partitions 1118 are welded between adjacent first partitions 1117. Finally, the two side plates 1116 are welded to the long side of the rear panel 1115 and to the ends of the first partitions 1117. Then, the front panel 1114 is welded to the support assembly, and the front panel 1114 is welded to the two side plates 1116, the first partitions 1117, and the second partitions 1118 to form the gearbox component 1111. Through the above steps, the structure of the support assembly is gradually formed, enhancing the stability of the gearbox.

[0022] Understandably, referring to Figure 3 The front panel 1114 and the rear panel 1115 are each evenly provided with a plurality of mounting holes 1119. The mounting holes 1119 are located in the area formed between the first partition 1117 and the second partition 1118, and the mounting holes 1119 on the front panel 1114 and the mounting holes 1119 on the rear panel 1115 are correspondingly provided. The mounting holes 1119 of the front panel 1114 are provided with round sleeves 1112, which are welded to the end face of the mounting holes 1119 of the front panel 1114. A first stiffening plate 1113 is connected between two adjacent round sleeves 1112. The mounting hole 1119 is located in the area formed between the first partition 1117 and the second partition 1118, which can prevent the front panel 1114 and the rear panel 1115 from being damaged due to uneven force on the mounting hole 1119. The round sleeve 1112 provides a stronger bearing surface for the installation of related mechanical components, while the first stiffening plate 1113 disperses external force by connecting adjacent round sleeves 1112, reducing the pressure on a single mounting point and ensuring the safety and stability of the gearbox component 1111 during installation and use.

[0023] Understandably, referring to Figure 2The first guide component includes a first housing 1121 and two first guide modules 1122. The two first guide modules 1122 are symmetrically arranged on the first housing 1121, and the two first guide modules 1122 cooperate to form a first guide groove 1123. By symmetrically installing the two first guide modules 1122 on the first housing 1121, and by having the two first guide modules 1122 cooperate to form the first guide groove 1123, assembly is simple, construction difficulty is low, and construction costs are reduced.

[0024] Specifically, it can be understood that, referring to Figure 4 The first guide module 1122 includes a first upright plate 1125, a first support frame 1124 and a first guide plate 1127. The first upright plate 1125 and the first support frame 1124 are both mounted on the first housing 1121, and the first support frame 1124 is connected to one side of the first upright plate 1125. The first guide plate 1127 is located on the side of the first upright plate 1125 facing away from the first support frame 1124. The first upright plate 1125 is welded to the first housing 1121. The first upright plate 1125 is perpendicular to the mounting surface. The first support frame 1124 is welded to the first upright plate 1125 and also welded to the first housing 1121. The first support frame 1124 is located on the side of the first upright plate 1125 facing away from the first guide plate 1127, providing strong support for the first upright plate 1125. The first upright plate 1125 is also provided on the side where the first guide plate 1127 is located, which enables the first guide groove 1123 to stably provide guidance. The structure is simple and effective, the construction difficulty is low, the construction efficiency is improved, and the construction cost is reduced.

[0025] Furthermore, it is understandable that, referring to Figure 4 A first pad 1128 is provided between the first guide plate 1127 and the first upright plate 1125. The first pad 1128 can reduce the pressure of the first guide plate 1127 on the first upright plate 1125, thereby improving the stability of the first upright plate 1125. Along the length direction of the first guide groove 1123, first stop plates 1126 are provided at both ends of the first pad 1128. The first stop plates 1126 are welded to the first upright plate 1125, and the first stop plates 1126 are welded to the first pad 1128 and the first guide plate 1127 to prevent the first pad 1128 and the first guide plate 1127 from slipping after long-term use, thereby improving the stability of the first guide plate 1127. The structure is simple and reduces the construction difficulty.

[0026] Understandably, referring to Figure 5 and Figure 6The second guide bracket 120 includes a second housing 1211 and a third housing 1212. One end of the second housing 1211 protrudes to form a plug-in portion 1227, and the third housing 1212 has a plug-in interface 1228. The plug-in portion 1227 and the plug-in interface 1228 are plugged into each other, connecting the second housing 1211 and the third housing 1212. The plug-in portion 1227 and the plug-in interface 1228 enable quick docking between the second housing 1211 and the third housing 1212, followed by welding for fixation. This allows the two parts to fit together to form an integral second guide bracket 120. The plug-in structure facilitates assembly, shortens the construction cycle, and ensures the strength and alignment accuracy of the connection.

[0027] Understandably, referring to Figure 5 The second guide component includes two second guide modules 1222, which are symmetrically arranged on the second housing 1211. The two second guide modules 1222 cooperate to form a second guide groove 1221, which cooperates with the first guide groove 1123 to form a guide channel.

[0028] Similarly, it is understandable that, by reference Figure 5 and Figure 6 The second guide module 1222 includes a second upright plate 1224, multiple second support frames 1223 and a second guide plate 1225. The second upright plate 1224 and multiple second support frames 1223 are all mounted on the second housing 1211. The multiple second support frames 1223 are all connected to one side of the second upright plate 1224. The second guide plate 1225 is located on the side of the second upright plate 1224 facing away from the second support frames 1223. The two second upright plates 1224 cooperate to form a second guide groove. The second upright plate 1224 is welded to the second housing 1211. The second upright plate 1224 is perpendicular to the mounting surface. The second support frame 1223 is welded to the second upright plate 1224 and also welded to the second housing 1211. The second support frame 1223 is located on the side of the second upright plate 1224 facing away from the second guide plate 1225, providing strong support for the second upright plate 1224 and enabling the second guide groove 1221 to stably provide a guiding function. The structure is simple and effective, the construction difficulty is low, the construction efficiency is improved, and the construction cost is reduced.

[0029] It is also understandable that, referring to Figure 5 and Figure 6A second pad (not shown in the attached figure) is provided between the second guide plate 1225 and the second upright plate 1224. The second pad can reduce the pressure of the second guide plate 1225 on the second upright plate 1224, thereby improving the stability of the second upright plate 1224. Along the length direction of the second guide groove 1221, second stop plates 1226 are provided at both ends of the second pad. The second stop plates 1226 are welded to the second upright plate 1224, and the second stop plates 1226 are welded to the second pad and the second guide plate 1225 to prevent the second pad and the second guide plate 1225 from slipping after long-term use, thereby improving the stability of the second guide plate 1225. The structure is simple and reduces the construction difficulty.

[0030] Understandably, referring to Figure 7 The support unit 200 includes a support plate 210 and a fourth housing 230. The fourth housing 230 is disposed on the upper end of the support plate 210. The support plate 210 is provided with a second stiffener 221 and a third stiffener 222. The second stiffener 221 is arranged along the width direction of the support plate 210, and the third stiffener 222 is arranged along the length direction of the support plate 210. The second stiffener 221 and the third stiffener 222 intersect. The cross-arranged second stiffener 221 and third stiffener 222 evenly distribute the load, prevent local buckling, improve the overall structural stiffness, enhance the load-bearing capacity and deformation resistance of the support plate 210, and ensure the overall stability of the lifting structure. In addition, the fourth housing 230 increases the contact area, facilitating the installation of the operating platform.

[0031] In summary, this embodiment of the invention provides a lifting base structure. By decomposing the lifting base structure into a guide unit 100 and a support unit 200, and the guide unit 100 further subdivided into a first guide bracket 110 and a second guide bracket 120, the lifting base structure is assembled from multiple components, which facilitates manufacturing. Before assembly, the gearbox component 1111 and the first guide component are assembled together. At the same time, the second guide component is assembled onto the second guide bracket 120, reducing the assembly difficulty. Then, the second guide bracket 120 is hoisted and fixed in place before the gearbox component is assembled. The guide unit 100 is initially installed by welding 1111 to the upper end of the second guide bracket 120. Then, each guide unit 100 is installed circumferentially. The support unit 200 is then placed between two adjacent guide units 100 and closed. Finally, the guide unit 100 and the support unit 200 are welded together to complete the installation of the lifting base structure. By decomposing the lifting base structure into guide units 100 and support units 200, and further disassembling the guide units 100 and support units into multiple component structures, and then welding and assembling these multiple components together, the construction difficulty is reduced and the construction efficiency is improved.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the counting principle of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
