Description

Technical Field

[0001] The utility model relates to the technical field of engineering survey trolleys, in particular to a driving chassis of an above-water sampling trolley. Background Art

[0002] Water survey, also known as water drilling, is a drilling project that conducts geological drilling on underwater strata in rivers, lakes, and seas to obtain data for underwater engineering geological surveys, water sample basic treatment, and solid mineral exploration. It can be used for engineering geological surveys, mineral resource exploration, foundation engineering construction, underwater mineral mining, and scientific investigations.

[0003] However, the existing underwater survey methods generally rely on towing the hull to the waterline position in the corresponding water area for sampling. The sampling methods are complicated, and the difficulty in turning the equipment is an inherent problem for small lakes. For this reason, the sampling method of engineering machinery automation through water vehicles is becoming more and more mainstream, but the existing water vehicles still have a series of problems such as rollover and unstable guidance.

[0006] Furthermore, the cross-section of the triangular pillow block is an equilateral structure, and each of the underwater crawlers is fixedly welded to the triangular pillow block at the vertex of the same angle and is arranged flush with the edge line of the three-axis pillow block.

[0007] Furthermore, the underwater crawler installation positions on both sides of each driving shaft are consistent, and in the forward direction of the trolley, the height of the initial position of the vertex of the triangular pillow blocks on the three driving shafts connected to the underwater crawler gradually decreases.

[0008] Furthermore, the length of the underwater crawler is not less than twice the height of the base.

[0012] Furthermore, the outer edge surface of the underwater track is covered with texture.

[0013] Compared with the prior art, the beneficial effects of the utility model include: using a segmented underwater crawler similar to a water slurry for driving, and through the synchronous rotation of six groups of underwater crawlers, it can stir the water surface in a unified water entry direction, thereby pushing the vehicle base forward in the opposite direction. In order to prevent the base from tipping over and the guide from being unstable, the drive shaft in the middle position is extended to stir the water flow on the outer side of the base, indirectly ensuring the smooth rotation of the underwater crawlers on the two drive shafts at the inner end.

[0019] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0020] According to one embodiment of the present invention, Figure 1-Figure 3 Shown.

[0021] In this embodiment, a driving chassis of an aquatic sampling vehicle includes: a square-structured base 1 and multiple groups of underwater tracks 2, wherein three drive shafts 3 are rotatably connected to the two sides of the long side of the base 1 at equal intervals in sequence, and the two ends of the drive shaft 3 are exposed from the base 1, and the length of the drive shaft 3 in the middle is greater than the length of the drive shaft 3 at the two ends. The underwater tracks 2 are integrally injection-molded, and are segmented structures with arc-shaped cross-sections. One end of each underwater track 2 is coaxially fixed to the drive shaft 3 through a triangular pillow block 4, and the other end is curved to be flush with the bottom surface of the base 1. The three drive shafts 3 rotate synchronously in the base 1 through a motor and a transmission belt. The cross-section of the triangular pillow block 4 is an equilateral structure, and each underwater track 2 is fixedly welded to the vertex of the same angle as the triangular pillow block 4 and is flush with the edge line of the three-axis pillow block.

[0022] Furthermore, the installation positions of the underwater tracks 2 on both sides of each of the drive shafts 3 are consistent, and in the forward direction of the trolley, the height of the initial position of the vertex of the underwater tracks 2 connected to the triangular pillow blocks 4 on the three drive shafts 3 gradually decreases. The length of the underwater track 2 is not less than the height of two of the base 1. The base 1 is made of polyethylene. The base 1 is also provided with a sealing sleeve 5 on the part corresponding to the exposed shaft section of each drive shaft 3. One end of the sealing sleeve 5 is bolted to the base 1, and the other end is coaxially connected to each of the drive shafts 3 through a sealing flange 6. Each of the sealing flanges 6 is embedded with a ball bearing 7, and the drive shaft 3 is rotatably connected to the ball bearing 7. Corresponding to each side of the base 1, the outer end face of the sealing sleeve 5 on the drive shaft 3 located in the middle position is flush with the outer end faces of the triangular pillow blocks 4 on the other two drive shafts 3. The outer edge of the underwater track 2 is covered with a texture 8.

[0023] Through the above structure, the present application does not adopt the conventional method of driving through a worm gear at the rear of the trolley, but adopts a water-slurry-like and segmented underwater crawler 2 for driving. Through the synchronous rotation of six groups of underwater crawlers 2, it can stir the water surface in a unified water entry direction, thereby pushing the vehicle base 1 forward in the opposite direction. Furthermore, in order to prevent the base 1 from tipping over and the guide from being unstable, in this embodiment, the drive shaft 3 in the middle position is extended to stir the water flow on the outer side of the base 1, thereby indirectly ensuring the smooth rotation of the underwater crawler 2 on the two drive shafts 3 at the inner end. The overall structure is novel and ingenious, and the driving method is simple and reliable, which provides more possibilities for inner waterline sampling in complex small waters.

[0024] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
