[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 - Figure 4As shown, a lifting auxiliary device for welding annular sections of a ship hull includes a base plate 1 and a lifting column 2 fixed to the top of the base plate 1. A sliding frame 4 is provided on the surface of the lifting column 2, and an intelligent lifting platform 5 is provided inside the sliding frame 4. A construction platform 6 is installed on the top of the sliding frame 4. The base plate 1 facilitates the support of the lifting column 2. The sliding frame 4, together with the intelligent lifting platform 5, can lift people and goods to a specified height. It should be noted that the sliding frame 4 and the intelligent lifting platform 5 in this application are composed of the components in the prior art patent application No. 201920603352.4, including a first motor, a second motor, a fall arrestor, a lifting body, pulleys, driven gears, driving gears, mounting side plates, mounting outer frames, a first motor shaft, and a second motor shaft. Its principle is the same as that of the above-mentioned application, and will not be described in detail here. The construction platform 6 is a closed design, which can provide a closed welding environment and reduce the impact of weather on high-altitude operations.

[0021] The bottom of the base plate 1 is fixedly connected to a support leg 7, and the bottom of the support leg 7 is fixedly connected to an anti-slip seat 8. The top of the construction platform 6 is fixedly connected to a baffle 9, one side of which is designed at an angle. Each of the four corners of the base plate 1 is provided with a fixed seat 10, and a hydraulic rod 11 is fixedly connected inside the fixed seat 10. The piston end of the hydraulic rod 11 is fixedly connected to a positioning seat 12. The support leg 7 can provide stable support for the base plate 1. The anti-slip seat 8 is made of rubber, which can increase the friction between the support leg 7 and the base plate 1. The baffle 9 is designed at an angle and is fixed to the top of the construction platform 6, which can provide shade and rain protection. The fixed seat 10 can easily and securely fix the hydraulic rod 11. The hydraulic rod 11 can also be used to adjust the height between the base plate 1 and the ground, thereby ensuring the stability of the base plate 1.

[0022] The positioning seat 12 has mounting holes 13 for auxiliary positioning inside. The mounting holes 13 are arranged in an array. The base plate 1 has four sliding grooves 14 inside. A support plate 3 is fixedly connected inside the sliding grooves 14. One side of the support plate 3 is fixedly connected to the fixed seat 10. The support plate 3 is fixed to the base plate 1 by screws. It is set inside the positioning seat 12 through the mounting holes 13. It can help to cooperate with the positioning pin to cone into the ground to ensure the stability of the base plate 1. Through the arrangement of the sliding grooves 14 and the support plate 3, the position of the positioning seat 12 driving the hydraulic rod 11 can be adjusted. The position of the support plate 3 inside the sliding groove 14 can be adjusted by removing the screws. Thus, the support range can be increased according to the construction situation before use.

[0023] Working Principle: First, the lifting column is fixed with two segmented screws for easy disassembly and assembly. The sliding frame 4, in conjunction with the intelligent lifting platform 5, can raise personnel and goods to a designated height. The main body of the lifting platform is equipped with a first motor and a second motor. The two motors drive two drive gears to rotate, and each drive gear drives two driven gears to rotate. All four driven gears have teeth that mesh with the rack on the external column, allowing them to move upward and downward. At the same time, the entire lifting platform is also equipped with multiple pulleys that slide tightly against the various sides of the column, ensuring that the driven gears mesh tightly with the rack without gaps or loosening. The rotation of the first and second motors drives the drive gears to rotate, which in turn drives the driven gears to rotate. The driven gears then mesh with the rack on the external column, causing the entire lifting platform to climb. Finally, the construction platform 6 is designed to be enclosed, which reduces the impact of the environment on high-altitude operations.

[0024] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
