[0018] 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.

[0019] Reference Figures 1-2 This utility model provides an embodiment of a trolley for transporting heavy metal parts, including a support plate 1. The support plate 1 is U-shaped and can slide to contact the ground, allowing heavy metal parts to slide onto it for transport. This lifts the metal parts and increases ease of placement. Screw assemblies are slidably connected to both ends of the support plate 1. The screw assembly includes a bracket 2, which consists of an upper square plate and a lower cylinder. The cylinder allows the support plate 1 to slide horizontally and vertically, while the square plate supports the screw lever 4 and the motor 3. The position is fixed. The upper end of the bracket 2 is fixedly connected to the motor 3. The lower output shaft of the motor 3 is fixedly connected to the screw lever 4. The motor 3 can drive the screw lever 4 to rotate. The lower part of the bracket 2 is fixedly connected to the upper ends of the base 9. The base 9 supports the bracket 2 and keeps it relatively fixed. The two ends of the bracket 2 are slidably connected to the inside of the side end of the support plate 1. The lower part of the screw lever 4 is rotatably connected to the inside of the upper end of the base 9. The rotation of the screw lever 4 can drive the support plate 1 to slide up and down to a suitable position for feeding and moving. The external thread of the screw lever 4 is connected to the inside of the side end of the support plate 1.

[0020] Reference Figures 1-3The lower part of the support plate 1 contacts a support assembly, which keeps the overall device relatively horizontal. The support assembly includes a base 9, and a pulley 10 is fixedly connected to the lower part of the base 9. The pulley 10 can drive the overall device to move. The upper part of the base 9 contacts the lower part of the support plate 1, and the base 9 can support the support plate 1. Square grooves 8 are fixedly connected to both ends of the upper part of the support plate 1. The square grooves 8 can restrict the T-shaped blocks 16 inside the side end to slide horizontally within a fixed distance. T-shaped blocks 16 are slidably connected inside the square grooves 8. T-shaped blocks 16 can support and keep the vertical groove 5 relatively fixed in a vertical state. A snap-fit ​​assembly is slidably connected inside the T-shaped blocks 16. The vertical groove 5 is fixedly connected to the side end of the T-shaped blocks 16. The vertical groove 5 can support the sliding rod 6 to slide vertically only and can fix it at different heights. The sliding rod 6 is slidably connected to the outside of the side end of the vertical groove 5. The sliding rod 6 can drive the clamping rod 15 at the lower end to slide up and down. It can clamp metal parts of different heights, and the U-shaped ends of the sliding rod 6 can keep the sliding rod 6 horizontal by being restricted by the vertical groove 5. The two ends of the sliding rod 6 are elastically connected to the locking rod 17 by spring 14. The locking rod 17 is L-shaped and can slide into the interior of the vertical groove 5 to keep the sliding rod 6 relatively fixed. The side of the locking rod 17 is slidably connected to the inside of the side end of the vertical groove 5. The locking rod 17 is restricted by the sliding rod 6 to slide horizontally. One end of the spring 14 is fixedly connected to the middle interior of the sliding rod 6, and the other end of the spring 14 is fixedly connected to the outside of the side end of the locking rod 17. The compression of the spring 14 can keep the outside of the side end of the locking rod 17 fixedly connected to the inside of the side end of the vertical groove 5. The middle interior of the sliding rod 6 is threaded with a bolt 7. The rotation of the bolt 7 can drive the clamping rod 15 to slide up and down relative to the sliding rod 6 so that the clamping rod 15 can clamp the metal parts. The lower part of the bolt 7 is rotatably connected to the clamping rod 15.

[0021] Reference Figure 1 , Figure 3 and Figure 4The snap-fit ​​assembly includes a snap-fit ​​block 12, which fixes the T-shaped block 16 in position relative to the square slot 8, preventing the clamping rod 15 from sliding horizontally. The upper part of the snap-fit ​​block 12 is slidably connected to the upper end of the square slot 8. Both ends of the upper part of the snap-fit ​​block 12 are arc-shaped surfaces. When the snap-fit ​​block 12 slides down, the arc-shaped surfaces are compressed and can slide into the interior of the T-shaped block 16. This allows the sliding rod 6 to drive the clamping rod 15 to slide horizontally to accommodate metal fittings with different placement positions and centers of gravity. Square blocks 11 are fixedly connected to both ends of the snap-fit ​​block 12, preventing the snap-fit ​​block 12 from sliding horizontally. The block 11 slides completely out of the upper end of the square groove 8. The outer part of the block 11 is slidably connected to the upper end of the T-shaped block 16. The T-shaped block 16 restricts the block 11 to slide vertically within a fixed distance. The lower part of the locking block 12 is elastically connected to the upper end of the T-shaped block 16 by a second spring 13. The compression of the second spring 13 can make the locking block 12 slide out. One end of the second spring 13 is fixedly connected to the upper end of the T-shaped block 16. The second spring 13 is compressed by the T-shaped block 16 to keep the locking block 12 in a compressed state. The other end of the second spring 13 is fixedly connected to the lower end of the locking block 12.

[0022] Working principle: The motor 3 drives the lever 4 to rotate. When the lever 4 is pressed, the support plate 1 slides down until its lower end contacts the ground. Then the motor 3 stops rotating, and the bracket 2 supports the support plate 1 to slide horizontally. Then, the heavy metal parts are slid to the upper part of the support plate 1 through sliding. Then the sliding block 12 slides down so that its upper end is completely inside the upper end of the square groove 8. With the horizontal sliding, the T-shaped block 16 and the vertical groove 5 can drive the sliding rod 6 to slide horizontally to the appropriate position. At this time, the block 12 slides upward under the pressure of the spring 13, driving the square block 11 to slide upward, until the upper end of the block 12 slides out of the upper end of the square groove 8 and the square block 11 is blocked by the T-shaped block 16. Until the block 16 is restricted, the locking rods 17 at both ends slide in the middle. The locking rods 17 slide out of the side end of the vertical groove 5 and squeeze the spring 14. Then they slide down to a suitable height so that the lower clamping rod 15 is close to the metal part. Then they are released so that the locking rod 17 slides into the side end of the vertical groove 5 under the compression of the spring 14, keeping the sliding rod 6 relatively fixed. Then the bolt 7 is rotated to drive the lower clamping rod 15 to slide down and clamp the metal part. Then the motor 3 is started. The motor 3 drives the screw lever 4 to rotate. The screw lever 4 rotates and squeezes so that the support plate 1 slides horizontally to a suitable position. Then the motor 3 is stopped to keep the position of the support plate 1 fixed.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
