[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Referring to Figures 1-4 , an embodiment provided by the present utility model: A steel pipe transfer trolley includes:

[0027] Two support plates 1, and two slide bars 6 are fixedly connected to the adjacent sides of the two support plates 1 to support the overall structure of the trolley. The middle of the slide bar 6 is fixedly connected to a fixed plate 7, and two slide plates 8 are slidably connected to the outer wall of the slide bar 6. The two ends of the fixed plate 7 and the slide plate 8 are fixedly connected to a mounting shaft 9, and the middle of the fixed plate 7 is rotatably connected to a bidirectional threaded rod 4 to adjust the distance between the slide plate 8 and the fixed plate 7;

[0028] Multiple fixed rings 11. The upper fixed ring 11 is connected to the lower fixed ring 11 through the cooperation between the lock block 13 and the lock housing 12 to fix the transported steel pipes. The bottom side of the lower fixed ring 11 is connected to the mounting shaft 9 through the insertion between the positioning block 14 and the positioning groove 15 to connect the threads on the outer wall of the lower fixed ring 11 and the outer wall of the mounting shaft 9. Both top sides of the two support plates 1 are fixedly connected with guardrails 2. Both separated sides of the two guardrails 2 are fixedly connected with handles 3. The outer wall of the handle 3 is provided with anti-slip patterns. Anti-slip pads are arranged on both sides of the upper fixed ring 11 and the lower fixed ring 11 that are close to each other. Multiple wheels are installed on the bottom sides of the two support plates 1 through wheel frames;

[0029] Specifically, the fixation between the two slide bars 6 and the two support plates 1 can not only support and fix the overall structure of the trolley, but also provide support for the sliding of the two slide plates 8. At the same time, by controlling the rotation of the bidirectional threaded rod 4 to adjust the distance between the slide plate 8 and the fixing plate 7, the weight of the fixed steel pipe can be better dispersed to the trolley, avoiding the trolley being bent due to concentrated downward pressure and affecting the service life of the trolley. The upper fixed ring 11 and the lower fixed ring 11 fix the transported steel pipe through the cooperation between the lock housing 12 and the lock block 13, preventing the steel pipe from sliding on the trolley. At the same time, the connection between the lower fixed ring 11 and the mounting shaft 9 is realized through the threaded sleeve 10, facilitating the fixation of the fixed ring 11 according to the sizes of different steel pipes and improving the practicality of the trolley. The anti-slip pads on the fixed ring 11 can better fix the steel pipe, facilitating the transportation of the steel pipe.

[0030] Refer to Figure 1 、 Figure 3 and Figure 4 As shown in, the lock block 13 located on the outer wall of the fixed ring 11, the upper lock block 13 and the lower lock block 13 are threadedly connected with the lock housing 12 on the outer wall. The positioning block 14 located at the bottom end of the lower fixed ring 11 and the positioning groove 15 opened on the top side of the mounting shaft 9. The positioning block 14 is arranged inside the positioning groove 15. The outer wall of the mounting shaft 9 is threadedly connected with a threaded sleeve 10. The threaded sleeve 10 is threadedly connected to the outer wall of the lower fixed ring 11. Both slide plates 8 are threadedly connected to the outer wall of the bidirectional threaded rod 4. The front end of the bidirectional threaded rod 4 is fixedly connected with a roller 5;

[0031] Specifically, through the connection of the upper lock block 13 and the lower lock block 13 by the lock housing 12 to connect the two fixed rings 11, the steel pipe is fixed on the trolley. Through the insertion between the positioning block 14 and the positioning groove 15, the threads on the outer wall of the lower fixed ring 11 and the threads on the outer wall of the mounting shaft 9 are connected, facilitating the clamping of the threaded sleeve 10 at the connection between the lower fixed ring 11 and the mounting shaft 9, facilitating the replacement of the fixed ring 11 according to different sizes of steel pipes, facilitating the operation of the trolley for steel pipes, and improving the practicality of the trolley at the same time.

[0032] Working principle: First, rotate the roller 5 to control the rotation of the bidirectional threaded rod 4 in the middle of the fixed plate 7, so as to control and adjust the distance between the sliding plate 8 and the fixed plate 7. Then, by rotating the lock housing 12, it is convenient to open the two fixing rings 11. Then, the steel pipe is clamped on the adjacent sides of the upper and lower fixing rings 11. Then, the upper fixing ring 11 and the lower fixing ring 11 are combined together, and the lock housing 12 is connected to the outer walls of the two fixing rings 11 to fix the steel pipe on the trolley. Then, by holding the handle 3, it is convenient to transport the steel pipe through the wheels. At the same time, according to the size of the steel pipe, by rotating the threaded sleeve 10, it is convenient to disassemble the fixing ring 11 from the mounting shaft 9, so as to replace different fixing rings 11 according to different steel pipe sizes and better fix the steel pipe.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
