DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0024] Reference Figure 1 - Figure 3 An embodiment provided by the present application is a kind of adjustable sling device for construction hoisting, including mounting plate 1 and, mounting block 2, the inner wall of mounting block 2 is slidably connected with arc-shaped sliding groove one 4, the outer wall of arc-shaped sliding groove one 4 is fixedly connected with rotating block 3, the front and rear two sides of the inner wall of rotating block 3 are rotatably connected with arc-shaped sliding groove two 6, the outer wall of arc-shaped sliding groove two 6 is fixedly connected with clamping block 5, the front and rear two sides of clamping block 5 are provided with recess, the upper and lower ends of recess are fixedly connected with fixed rod 8, the inner wall of fixed rod 8 is slidably connected with sliding rod 9, the inner wall of fixed rod 8 is provided with spring 10, one end of sliding rod 9 is fixedly connected with anti-skid roller 7, one end of spring 10 is connected with the inner wall of fixed rod 8, the other end of spring 10 is connected with the outer wall of sliding rod 9, rotating block 3 and clamping block 5 are semicircular, arc-shaped sliding groove one 4 and arc-shaped sliding groove two 6 are also semicircular, the top left and right sides of mounting plate 1 are fixedly connected with mounting buckle 17, the bottom front and rear sides of mounting plate 1 are fixedly connected with limiting rod 16, one end of connecting plate 15 is slidably connected with the outer wall of limiting rod 16.

[0025] Specifically, the inner wall of the mounting block 2 is in sliding connection with the arc-shaped sliding groove 4, which enables the arc-shaped sliding groove 4 to slide relative to the mounting block 2, thereby providing a certain activity basis for the position adjustment of the subsequent connected components. The outer wall of the arc-shaped sliding groove 4 is fixedly connected with the rotating block 3, so that when the arc-shaped sliding groove 4 slides in the mounting block 2, the rotating block 3 is synchronously moved, and the two form a linked structure unit. The rotating block 3 is semicircular, and the arc-shaped sliding groove 4 is also semicircular, which are mutually adapted in shape to ensure the stability of the connection and the coordination during the sliding process. The inner walls of the front and rear sides of the rotating block 3 are both in rotational connection with the arc-shaped sliding groove 6, which enables the arc-shaped sliding groove 6 to rotate relative to the rotating block 3, and gives the subsequent connected clamping block 5 the function of rotatable adjustment, so that the angle can be flexibly changed to adapt to different shapes and sizes of the hoisted objects. The outer wall of the arc-shaped sliding groove 6 is fixedly connected with the clamping block 5, so that when the arc-shaped sliding groove 6 rotates relative to the rotating block 3, the clamping block 5 also rotates. The clamping block 5 is also designed to be semicircular, and cooperates with the rotating block 3 to perform operations such as wrapping and clamping on the object. The clamping block 5 is adapted in shape with the rotating block 3 and the related arc-shaped sliding groove to form an adjustable clamping structure that can flexibly adjust the angle and position to adapt to different shapes and sizes of the hoisted objects.

[0026] Grooves are formed on the front and rear sides of the clamping block 5, and the fixed rod 8 is fixedly connected to the upper and lower ends of the grooves to provide a fixed support structure for the installation and movement of the subsequent components. The sliding rod 9 is in sliding connection with the inner wall of the fixed rod 8, enabling the sliding rod 9 to slide linearly along the axial direction of the fixed rod 8. This sliding connection provides a basic condition for the position adjustment of the anti-skid roller 7. The anti-skid roller 7 is fixedly connected to one end of the sliding rod 9, so that the sliding of the sliding rod 9 drives the anti-skid roller 7 to move synchronously. The spring 10 is arranged in the inner wall of the fixed rod 8, with one end connected to the inner wall of the fixed rod 8 and the other end connected to the outer wall of the sliding rod 9. When the sliding rod 9 slides in the fixed rod 8, the spring 10 is compressed or stretched. The spring 10 relies on its elastic deformation to generate a restoring force acting on the sliding rod 9, so that the sliding rod 9 drives the anti-skid roller 7 to automatically reset after moving under the action of a certain external force, ensuring that the anti-skid roller 7 always maintains appropriate contact pressure with the clamped object and maintains good anti-skid effect.

[0027] Mounting buckles 17 are fixedly connected to the top left and right sides of the mounting plate 1. Through the mounting buckles 17, the entire lifting device can be easily connected to external lifting equipment such as the hook of a crane to realize the lifting function. It is the key part of the entire device to connect with the lifting power source. Limiting rods 16 are fixedly connected to the bottom front and rear sides of the mounting plate 1, which provide the mounting foundation and movement guide for the connecting plate 15 connected to it, limit the sliding direction of the connecting plate 15, and ensure that it can slide orderly and stably on the outer wall of the limiting rod 16. One end of the connecting plate 15 is slidably connected to the outer wall of the limiting rod 16. This sliding connection method allows the connecting plate 15 to be adjusted in position relative to the mounting plate 1. With the limiting effect of the limiting rod 16, the movement of the connecting plate 15 is in a controllable and standardized state, which is conducive to the flexible use of the device under different working conditions and the expansion of other functions.

[0028] Reference Figure 1 , Figure 4 and Figure 5 A motor 11 is mounted on the top of the mounting plate 1. A gear 12 is fixedly connected to the drive end of the motor 11. A toothed plate 13 is meshed with the front outer wall of the gear 12. A toothed plate 14 is meshed with the rear outer wall of the gear 12. A connecting plate 15 is fixedly connected to the bottom ends of both the toothed plate 13 and the toothed plate 14. The bottom end of the connecting plate 15 is fixedly connected to the top of the mounting block 2.

[0029] Specifically, the motor 11 is mounted on the top of the mounting plate 1, and the drive end of the motor 11 is fixedly connected to the gear 12. This means that when the motor 11 starts running, it can directly drive the gear 12 to rotate. Then, the front outer wall of the gear 12 meshes with the first gear plate 13, and the rear outer wall meshes with the second gear plate 14. This meshing connection allows the gear 12 to drive the first gear plate 13 and the second gear plate 14 to perform corresponding linear motion through the interaction between the teeth during rotation. Since toothed plates 13 and 14 are located on the front and rear sides of gear 12 respectively and mesh with it, their directions of movement are opposite. Finally, the bottom ends of toothed plates 13 and 14 are fixedly connected to connecting plates 15, and the bottom end of connecting plates 15 is fixedly connected to the top end of mounting block 2. In this way, the linear movement of toothed plates 13 and 14 will be transmitted to mounting block 2 through connecting plates 15, causing mounting block 2 to make corresponding position adjustments, thereby affecting the position and state of a series of subsequent components such as arc-shaped slide groove 4 and rotating block 3 connected to it, realizing part of the adjustment function of the entire adjustable lifting device during the lifting process.

[0030] Working principle: The mounting buckles 17 on both sides of the top of the mounting plate 1 are connected to external lifting equipment, enabling the device to obtain lifting power and start the lifting operation. The limiting rod 16 at the bottom of the mounting plate 1 provides installation and guidance for the connecting plate 15, allowing the connecting plate 15 to slide on its outer wall to achieve position adjustment to adapt to different working conditions. After the motor 11 starts, it drives the gear 12 to rotate. Through the meshing of the gear 12 with the first gear plate 13 and the second gear plate 14, the gear plates 13 and 14 are driven to move linearly in opposite directions. The gear plates 13 and 14, through the connecting plate 15 at the bottom, drive the mounting block 2 to adjust its position. The first adjustment function of the device is achieved by sliding the arc-shaped slide groove 4 inside the mounting block 2, which drives the rotating block 3 to move synchronously. The rotating block 3 allows the clamping block 5 to be rotated and adjusted through the arc-shaped slide groove 6, thus forming an adjustable clamping structure that can adapt to objects of different shapes and sizes. The second adjustment function is achieved by fixing the fixing rod 8 in the groove of the clamping block 5, and sliding the slide rod 9 on its inner wall to drive the anti-slip roller 7 to move. The position is changed according to the surface condition of the clamped object. At the same time, with the help of the restoring force of the spring 10, the anti-slip roller 7 maintains a suitable contact pressure to play an anti-slip role, thus achieving the third adjustment function and ensuring the stability of the hoisting.

[0031] 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.
