DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0022] The utility model discloses a mechanical crane arm for mechanical processing, which is mainly applied to the traditional crane arm used in the mechanical processing industry. Generally, after being connected with the workpiece by a hook, the rope on the hook is rolled up to suspend the workpiece. During the suspension process, due to the soft telescopic effect, the workpiece is easy to shake in windy weather, and the workpiece may even fall down in severe cases.
[0023] Reference Figure 1 , Figure 2 and Figure 4 A mechanical boom for mechanical processing includes a base 1 and a column 2 arranged at the upper end of the base 1, a cantilever 3 is installed on the top of the column 2, a reel 4 is arranged at one end of the cantilever 3, a pull rope 5 is wound in the reel 4, and a hook 7 is arranged at the end of the pull rope 5, and also includes: an auxiliary suspension mechanism: the auxiliary suspension mechanism includes a first threaded rod 8 arranged on one side of the hook 7, a threaded docking sleeve 9 is threadedly connected to the first threaded rod 8, a rear end of the threaded docking sleeve 9 is rotatably connected to a cross plate 10, and a rear end of the cross plate 10 is rotatably connected to a folding piece for following the movement of the hook 7.
[0024] In this solution, the pull rope 5 is retracted and released by the unwinder 4, and the workpiece is suspended by the hook 7. The workpiece is suspended to a specific position through the cooperation between the components. In windy weather, after the threaded docking tube 9 is threadedly connected to the first threaded rod 8, the folding part thereof will unfold or fold following the up and down movement of the hook 7, thereby limiting the workpiece and preventing the workpiece from shaking.
[0025] Reference Figure 1 and Figure 3 In a preferred embodiment, the folding member includes a first connecting frame 11 rotatably connected to the rear end of the cross plate 10, a connecting arm 12 is fixedly provided on one side of the first connecting frame 11, and a steering member for cooperating with the rotation of the end of the cantilever 3 is fixedly provided on one end of the connecting arm 12, and a rotating arm 21 is fixedly provided on one end of the universal joint 13, and a second connecting frame 14 is rotatably connected to the rear end of the rotating arm 21, a support arm 15 is fixedly provided on one side of the second connecting frame 14, and a third connecting frame 16 is fixedly provided on the rear end of the support arm 15, and a sliding member for sliding up and down is rotatably connected in the third connecting frame 16.
[0026] During the up and down movement of the hook 7, the cross plate 10 will be driven to move simultaneously. During the movement of the cross plate 10, the angle with the connecting arm 12 will change through the first connecting frame 11. Under the action of the universal joint 13, even if the end of the cantilever 3 is rotated artificially, its folding part will also rotate accordingly. Under the action of the second connecting frame 14 and the third connecting frame 16, the angles of the support arm 15 and the rotating arm 21 will also change along with the up and down movement of the hook 7.
[0027] Among them, the sliding part includes a slider 17 rotatably connected in the third connecting frame 16, a guide rail 18 is fixedly arranged on the outer peripheral surface of the column 2, the slider 17 is slidably connected in the guide rail 18, and a locking part for fixing the supporting angle is arranged in the third connecting frame 16. When the hook 7 moves downward to a point where it cannot be reached even if the folding part is fully unfolded, the slider 17 will be dragged to move downward along the guide rail 18, thereby increasing the downward movement range of the hook 7.
[0028] Reference Figure 2 and Figure 3 In a preferred embodiment, the locking member includes a locking bolt 19 threadedly connected to the third connecting frame 16, a threaded hole 20 is opened on the slider 17, the locking bolt 19 is consistent with the threaded hole 20 in size, a second threaded rod 22 is fixedly provided below the other end of the cantilever 3, and locking members are provided between the cross plate 10 and the first connecting frame 11 and between the second connecting frame 14 and the rotating arm 21.
[0029] Specifically, the second threaded rod 22 is arranged at an angle, and the minimum angle between the second threaded rod 22 and the cantilever 3 is 45°. After the second threaded rod 22 is threadedly connected to the threaded docking sleeve 9 and the folding piece is fully unfolded, the threaded holes 20 correspond to the positions of the locking bolts 19 one by one, and the locking bolts 19 at each joint are screwed into the threaded holes 20, so that the unfolded state of the folding piece can be fixed, thereby improving the stability of the support for the cantilever 3.
[0030] Reference Figure 1 and Figure 3 In a preferred embodiment, one end of the pull rope 5 passes through the cantilever 3 and is fixedly provided with a counterweight 6, and the hook 7 is fixedly installed at the lower end of the counterweight 6.
[0031] It is worth noting that the gravity when the counterweight 6 and the hook 7 are combined is much greater than the friction force at the joint of the folding part, preventing the hook 7 from being unable to move downward stably.
[0032] Working principle: When in use, after the threaded docking tube 9 is threadedly connected to the first threaded rod 8, when the counterweight block 6 and the hook 7 move downward, the cross plate 10 follows the movement, driving the folding part at the tail end to unfold. Similarly, when the counterweight block 6 and the hook 7 move upward, the folding part will be driven to fold. When it moves to a high place, the folding part will unfold again, thereby limiting the position of the hook 7 without affecting the suspension of the workpiece by the hook 7, so that the hook 7 will not shake at will even in windy weather, thereby improving the stability of the suspended workpiece.
[0033] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited to them. The replacement can be a replacement of part of the structure, device, method steps, or a complete technical solution. Equivalent replacement or changes based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
