Description

Technical Field

[0001] The utility model relates to the technical field of shaft part transportation equipment, and particularly relates to an electric transporter for logging instruments. Background Art

[0002] Logging instruments are important equipment for geological exploration and oil exploitation. By emitting electromagnetic waves or other signals underground and receiving the reflected signals, they analyze the physical properties of underground rock formations. Such equipment can provide key information such as underground structures, rock types, and hydrogeological conditions, and plays a crucial role in the exploration and development of oil and natural gas. Due to the core position of logging instruments in geological exploration, their performance and accuracy directly affect the accuracy and reliability of exploration results. Therefore, the design and manufacture of logging instruments require a high level of technical expertise to ensure stable operation in various complex underground environments.

[0003] However, logging instruments are usually large in volume and heavy in weight, which poses quite a challenge to their handling and transportation. At oil fields or geological exploration sites, logging instruments need to be frequently moved from one well position to another. The traditional manual handling method is not only time-consuming and laborious but also poses a risk of damaging the equipment.

[0004] In view of this problem, the development of logging instrument transportation tools is particularly important. For example, the Chinese utility model patent with the publication number CN215043022U discloses a special translation cart for oil and gas well logging instruments, which includes a base, a column assembly, and an instrument support plate assembly; the column assembly includes a first column group and a second column group, and both the second column group and the first column group are composed of four columns. The first column group and the second column group are respectively fixed at both ends of the base; the instrument support plate assembly includes a first instrument support plate, a second instrument support plate, and a third instrument support plate. The third instrument support plate is fixed on the base, and the first instrument support plate and the second instrument support plate are respectively fixed above the first column group and the second column group; the first instrument support plate, the second instrument support plate, and the third instrument support plate are all arranged in a wavy structure; universal wheels are arranged at the four corners of the lower part of the base.

[0005] However, through research by the applicant, it is found that the above-mentioned existing logging instrument transportation tools only rely on manual pushing and pulling to move the cart for handling logging instruments, and manual labor is required to change the moving direction of the cart, resulting in a large manual labor intensity and the need to further improve the handling efficiency.
