When transporting cargo, especially tubular cargo, it will be affected by factors such as vehicle bumps and will be subject to a lateral force, that is, it is easy to roll to both sides. When the force is large enough, it is not possible to ensure the full stability of the cargo by only clamping the tail of the cargo. In view of this, we propose a cargo transportation clamping mechanism. Utility Model Content

[0023] like Figure 1-3 As shown, the utility model provides a technical solution: a cargo transportation clamping mechanism, including a base 1, the top of the base 1 is fixedly connected to the bottom of a base plate 2, the left and right side walls of the base plate 2 are provided with rectangular grooves 3, the inner side walls of the base plate 2 are fixedly connected to the side walls of a fixed plate 4, a bracket 5 is fixedly installed on the top of the base 1, a groove bottom block 6 is fixedly installed on the top of the base plate 2, and a clamping assembly 7 is arranged on the top of the base 1.

[0024] In one embodiment of the present invention, the clamping assembly 7 includes a slide rail 71, and the left and right side walls of the bottom plate 2 are fixedly connected to the side walls of the slide rail 71. The inside of the slide rail 71 is slidably connected to the outer wall of the bottom end of the U-shaped frame 72. When the round tubular cargo is loaded and it is to be clamped, the U-shaped frame 72 is moved to slide on the slide rail 71, and the inner wall of the center of the top of the U-shaped frame 72 is threadedly connected to the threaded rod 73, and moved to the approximate middle position of the cargo. At this time, the threaded rod 73 is rotated, and when the bottom end of the threaded rod 73 contacts the top of the clamping plate 77, it will Drive the clamping plate 77 to move downward together, the arc-shaped inner walls on both sides of the top of the U-shaped frame 72 are sleeved with cylinders 74, and the cylinders 74 also move downward together at this time. A disk 75 is fixedly installed on the top of the cylinder 74, and a tight spring 76 is sleeved on the arc-shaped outer wall of the cylinder 74. The top of the tight spring 76 fits the bottom of the disk 75, and the bottom of the tight spring 76 fits the top of the U-shaped frame 72. A clamping plate 77 is fixedly installed at the bottom of the cylinder 74. The rectangular groove 3 and the slide rail 71 are provided with two groups, and both are mirrored on the left and right sides thereof with the horizontal midline of the bottom plate 2 as the mirror axis. The clamping spring 76 is compressed and deformed. When the clamping plate 77 contacts the top of the cargo, the threaded rod 73 stops rotating, so that the clamping plate 77 can clamp and fix the cargo. The two sides of the U-shaped frame 72 can also fix the two ends of the cargo. The groove bottom block 6 is provided with multiple groups, and they are parallel to each other. The side walls are fitted together. The raised outer walls on both sides of the bottom of the U-shaped frame 72 are slidably connected to the inner walls of the two slide rails 71, so that the U-shaped frame 72 can slide while maintaining stability. The cylinder 74, the disc 75 and the clamping spring 76 are provided with two The U-shaped frame 72 is symmetrically arranged with the vertical center line of the U-shaped frame 72 as the symmetry axis. The clamping plate 77 is located directly below the threaded rod 73. The top of the U-shaped frame 72 is provided with a threaded through hole that is compatible with the threaded rod 73, and a through hole that is compatible with the outer diameter of the cylinder 74. Further, when the clamping is completed, the threaded rod 73 is rotated in the opposite direction to move upward. At this time, the spring 76 gradually releases its accumulated elastic force, so that the disc 75 will move upward with the cylinder 74 to reset. In addition, the U-shaped frame 72 can slide and will not affect the loading and unloading of goods.

[0025] In one embodiment of the utility model, a moving mechanism 8 is provided on the top of the base 1, and a hydraulic cylinder 81 is fixedly installed on the top of the bracket 5. The hydraulic cylinder 81 is fixedly connected to one end of a V-shaped block 83 through its piston rod 82. When the tail of the round tubular cargo is to be clamped and fixed, the hydraulic cylinder 81 is started to extend its piston rod 82, thereby pushing the V-shaped block 83 toward the fixed plate 4. The end of the V-shaped block 83 away from the piston rod 82 is fixedly connected to the side wall of the support plate 84, thereby driving the support plate 84 to move in this direction, that is, to approach the tail of the round tubular cargo, so as to clamp and fix it. A round rod 85 is provided inside the rectangular groove 3. The two ends of the round rod 85 are fixedly connected to the side walls of the bottom plate 2, and the arc-shaped outer wall of the round rod 85 is slidably connected to the arc-shaped inner wall of the bottom end of the vertical rod 86. There are two groups of round rods 85 and vertical rods 86. The side walls at both ends of the support plate 84 are respectively fixedly connected to the two side walls of the vertical rods 86. When the support plate 84 moves, the vertical rod 86 also slides synchronously on the arc-shaped outer wall of the round rod 85. This can make the entire movement process smoother and the clamping effect better. The top of the support plate 84 is flush with the top of the vertical rod 86, but the former is smaller than the latter. The top of the groove bottom block 6 is located below the bottom of the support plate 84, so that there is no movement interference between the support plate 84 and the groove bottom block 6 during the movement.

[0026] Working principle: After loading the tubular cargo, to clamp it, the U-shaped frame 72 is moved to slide on the slide rail 71 to the approximate middle position of the cargo, and then the threaded rod 73 is rotated. When the bottom end of the threaded rod 73 contacts the top of the clamping plate 77, the clamping plate 77 is driven to move downward together. At this time, the cylinder 74 also moves downward together, and the clamping spring 76 is compressed and deformed. When the clamping plate 77 contacts the top of the cargo, the threaded rod 73 is stopped from rotating, so that the clamping plate 77 can clamp and fix the cargo, and the two sides of the U-shaped frame 72 can also fix the two ends of the cargo. Further, when the clamping is completed, the threaded rod 73 is rotated in the opposite direction to make it When the cylinder 74 is moved upward, the spring 76 gradually releases its stored elastic force, so that the disc 75 moves upward with the cylinder 74 to reset. In addition, the U-shaped frame 72 can slide, which will not affect the loading and unloading of goods. When the tail of the tubular goods is to be clamped and fixed, the hydraulic cylinder 81 is started to extend its piston rod 82, thereby pushing the V-shaped block 83 toward the fixed plate 4, thereby driving the push plate 84 to move in this direction, that is, to approach the tail of the tubular goods, so as to clamp and fix them. While the push plate 84 moves, the vertical rod 86 also slides synchronously on the arc-shaped outer wall of the round rod 85, so that the entire movement process can be smoother and the clamping effect is better.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
