Description

Technical Field

[0001] This utility model relates to the field of tool cart technology, specifically a small tool cart suitable for cleaning circular pipe culverts. Background Technology

[0002] A circular culvert is a type of culvert with a circular cross-section. Circular culverts require regular cleaning. Because they are relatively long, workers need to use tool carts to transport the cleaning tools. This makes it easier for workers to clean the culvert in a confined space. However, while the tool carts in the current technology can slide along the culvert, some culverts contain silt, which can easily cause the guide wheels to become clogged, preventing the tool cart from moving. This actually increases the workload for the workers. Summary of the Invention

[0003] Therefore, the purpose of this utility model is to provide a small tool cart suitable for cleaning circular culverts. Through the cooperation of the tool cart component and auxiliary components, the rollers of the tool cart can be switched during use. This allows the tool cart to be used in different culvert environments, avoiding the situation where muddy culverts affect the normal sliding of the tool cart. Furthermore, the switchable structure design makes it more flexible to use.

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a small tool cart suitable for cleaning circular pipe culverts, comprising:

[0005] A tool cart assembly, comprising a small cart frame, a triangular plate fixed to the side wall of the small cart frame, a connecting rope connected to the triangular plate, and directional wheels disposed on the bottom surface of the small cart frame;

[0006] The auxiliary component includes a concave frame fixed to the side wall of the directional wheel, a short shaft fixed inside the concave frame, a short sleeve fitted with the short shaft, a connecting plate connected to the short sleeve, an I-shaped rod penetrating the connecting plate, a threaded cylinder connected to the I-shaped rod, a threaded shaft connected to the threaded cylinder, a traveling wheel connected to the threaded shaft, and a strong magnet fixed to the outer wall of the trolley frame.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] This utility model provides a small tool cart suitable for cleaning circular culverts. Through the cooperation of the tool cart component and auxiliary components, the rollers of the tool cart can be switched during use. This allows the tool cart to be used in different culvert environments, avoiding the situation where muddy culverts affect the normal sliding of the tool cart. In addition, the switchable structure design makes it more flexible to use.

[0029] Figures 1-4 The diagram shown is an overall structural schematic of an embodiment of a small tool cart for cleaning circular culverts according to this utility model. Please refer to [link / reference]. Figures 1-4 The main structure of this embodiment includes: a tool cart assembly and an auxiliary assembly.

[0030] The tool cart assembly is used to place cleaning tools. Specifically, the tool cart assembly includes a small cart frame 11, a triangular plate 12 fixed to the side wall of the small cart frame 11, a connecting rope 13 connected to the triangular plate 12, and directional wheels 14 set on the bottom surface of the small cart frame 11.

[0031] In actual use, the user pulls the connecting rope 13 by hand, and the connecting rope 13 drives the trolley frame 11 to slide along the culvert through the directional wheel 14 so as to transfer the trolley tool.

[0032] The auxiliary components are used for roller switching to adapt to different walking environments. Specifically, the auxiliary components include a concave frame 21 fixed to the side wall of the directional wheel 14, a short shaft 22 fixed inside the concave frame 21, a short sleeve 23 fitted with the short shaft 22, a connecting plate 24 connected to the short sleeve 23, an I-shaped rod 25 penetrating the connecting plate 24, a threaded cylinder 26 connected to the I-shaped rod 25, a threaded shaft 27 connected to the threaded cylinder 26, a walking wheel 28 connected to the threaded shaft 27, and a strong magnet 29 fixed to the outer wall of the trolley frame 11. The side wall of the directional wheel 14 has a first threaded hole 141, and the connecting plate 24 has a second threaded hole 241.

[0033] In practical use, the user pulls down the connecting plate 24, which directly separates from the strong magnet 29. At this time, the connecting plate 24 rotates along the short shaft 22 through the short sleeve 23 until the first threaded hole 141 and the second threaded hole 241 are linked. Then, the user uses a threaded rod to lock the first threaded hole 141 and the second threaded hole 241, thus completing the switching of the traveling wheel 28. This allows it to be used in different culvert environments, avoiding the situation where muddy culverts affect the normal sliding of the tool vehicle. Furthermore, the user can easily replace the traveling wheel 28 through the threaded sleeve 26 and the threaded shaft 27, further improving the flexibility of use.

[0034] Furthermore, it also includes an assembly assembly, which includes a base plate 31 placed inside the trolley frame 11 and a notch 32 formed on the base plate 31; the assembly assembly also includes a long shaft 33 set in the notch 32, a long sleeve 34 fitted with the long shaft 33, and a first partition 35 connected to the long sleeve 34; the assembly assembly also includes a second partition 36 adjacent to the first partition 35; wherein, the second partition 36 is provided with a notch 32, a long shaft 33 and a long sleeve 34 of the same structure; the assembly assembly also includes an L-shaped limiting plate 37 set at the position of the second partition 36, and a first limiting groove 38 and a second limiting groove 39 formed on both sides of the L-shaped limiting plate 37;

[0035] In practical use, the first limiting groove 38 and the second limiting groove 39 are respectively fitted with the first partition 35 and the second partition 36. In this way, the L-shaped limiting plate 37 can limit the first partition 35 and the second partition 36. Then, the user places the entire base plate 31 in the trolley frame 11 to place the tools. After the cleaning work is completed, the user takes the base plate 31 out of the trolley frame 11 and then pulls out the L-shaped limiting plate 37. At this time, the first partition 35 is flipped along the long axis 33 by the long sleeve 34. By the same principle, the second partition 36 can also be laid flat, which makes it convenient to clean the base plate 31 where the tools are placed without dead angles.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
