Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting tooling technology, specifically a lifting tool for shot blasting. Background Technology
[0002] Shot blasting is the name of a mechanical surface treatment process. Shot blasting is used to remove surface oxide scale and other impurities and improve the appearance quality. During shot blasting, the workpiece is suspended inside the shot blasting machine by a hanger.
[0003] Currently, when shot blasting small and medium-sized workpieces, multiple workpieces need to be suspended on a hanger with a certain distance between them outside the shot blasting machine before being placed inside the machine. Existing hangers are generally fixed mechanisms. When placing them inside the shot blasting machine, the large size of the hanger makes it difficult to fit inside due to the distance between the multiple workpieces, resulting in inconvenience. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of the prior art by providing a shot blasting lifting device that reduces the width of the lifting device, making it easier for it to enter the shot blasting machine.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a shot blasting lifting device, including a hook, with connecting rods symmetrically installed on both sides of the lower end of the hook, and a mounting frame installed at the lower ends of the two connecting rods. A screw drive assembly is installed inside the mounting frame, and two drive blocks are movably installed on the screw drive assembly. Connecting plates are hinged to both ends of the drive blocks. A fixing rod is installed through a through hole at one end of the two connecting plates. A movable plate is installed at the lower end of the fixing rod. Several adjusting plates are hinged to the lower end of the movable plate. Adjusting plates are hinged to one end of each adjusting plate and to the lower end of the mounting frame at the other end. Hooks are installed at the lower ends of both adjusting plates.
[0006] Preferably, the screw drive assembly includes a handle and a rotating screw. The mounting bracket is U-shaped, and the rotating screw is rotatably mounted inside the mounting bracket. One end of the rotating screw extends to the outside of the mounting bracket, and a handle is installed at one end of the rotating screw. Two drive blocks are threadedly connected to the surface of the rotating screw.
[0007] Preferably, the lower end of the drive block is in contact with the bottom end of the mounting bracket.
[0008] Preferably, the rotating screw is a bidirectional screw.
[0009] Preferably, both the hook and the lifting hook are equipped with a rotating shaft through a through hole, and an anti-drop hook is installed at one end of the rotating shaft.
[0010] Preferably, the rear end of the anti-detachment hook is in contact with the hook and the lifting hook.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This application uses a threaded drive assembly to move two drive blocks. The movement of the two drive blocks can change the forming angle of the two connecting plates and the position of the moving plate. The smaller the forming angle of the two connecting plates, the farther the moving plate is from the mounting frame. Conversely, the distance between the hooks on the first and second adjusting plates can be changed, which makes it easier to adjust the distance of each workpiece after suspension, reduce the overall width of the hanger, and make it easier to put into the shot blasting machine.
[0013] 2. This application installs an anti-drop hook on the hook and the hook hook. The anti-drop hook can form a closed loop with the hook and the hook hook, which can effectively prevent the workpiece from accidentally falling off the hook during shot blasting. Attached Figure Description

[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] like Figures 1 to 3As shown, a shot blasting lifting device includes a hook 1. Connecting rods 2 are symmetrically mounted on both sides of the lower end of the hook 1. A mounting frame 3 is mounted on the lower ends of the two connecting rods 2. A screw drive assembly 4 is installed inside the mounting frame 3. Two drive blocks 5 are movably mounted on the screw drive assembly 4, allowing the screw drive assembly 4 to move the two drive blocks 5. Connecting plates 6 are hinged to both ends of the two drive blocks 5. A fixing rod 7 is threaded through a through hole at one end of each of the two connecting plates 6. A movable plate 8 is mounted at the lower end of the fixing rod 7. Several adjusting plates 9 are hinged to the lower end of the movable plate 8. One end of the adjusting plate 9 is hinged to the adjusting plate 10, and the other end of the adjusting plate 10 is hinged to the lower end of the mounting frame 3. Both the adjusting plate 9 and the adjusting plate 10 are equipped with hooks 11 at their lower ends. By controlling the two drive blocks 5 to move closer to each other, the forming angle of the two connecting plates 6 can be changed. The smaller the angle between the two connecting plates 6, the farther the moving plate 8 is from the mounting frame 3, and the farther the distance between the hooks 11 on the adjusting plate 9 and the adjusting plate 10 is. Conversely, the angle can be adjusted to change the distance of each workpiece after suspension, making it easier to change the overall width of the lifting device and to put it into the shot blasting machine.
[0020] Specifically, the screw drive assembly 4 includes a handle 401 and a rotating screw 402. The mounting bracket 3 is U-shaped, and the rotating screw 402 is rotatably mounted inside the mounting bracket 3. One end of the rotating screw 402 extends to the outside of the mounting bracket 3, and a handle 401 is installed at one end of the rotating screw 402. Two drive blocks 5 are threadedly engaged with the rotating screw 402. By rotating the handle 401, the rotating screw 402 is driven to rotate, and the rotating screw 402 drives the two drive blocks 5 to move, which facilitates the adjustment of the distance between the moving plate 8 and the mounting bracket 3, thereby realizing the adjustment of the distance between the hooks 11 on the first adjustment plate 9 and the second adjustment plate 10.
[0021] Furthermore, the lower end of the drive block 5 contacts the bottom of the mounting bracket 3, allowing the drive block 5 to move smoothly and preventing rotation during movement, thus serving a guiding function.
[0022] Furthermore, the rotating screw 402 is a bidirectional screw, which facilitates relative and opposite movement of the two drive blocks 5.
[0023] Furthermore, both the hook 11 and the hook 1 have a rotating shaft 12 installed on their surfaces through through holes. One end of the rotating shaft 12 is equipped with an anti-drop hook 13, which can rotate. The hook 11 and the anti-drop hook 13 are used in conjunction with the hook 1 and the hook 1 to achieve the function of preventing the hook 11 and the hook 1 from falling off.
[0024] Furthermore, the rear end of the anti-detachment hook 13 comes into contact with the hook 11 and the lifting hook 1.
[0025] The usage method of this embodiment is as follows: First, suspend the hook 1 on the track of the shot blasting machine. Then, suspend small to medium-sized workpieces outside the shot blasting machine. Insert both the hook 11 and the anti-drop hook 13 into the same hole in the workpiece to effectively prevent it from falling off. When it is necessary to insert the entire lifting device into the shot blasting machine, rotate the handle 401 to drive the rotating screw 402 to rotate. The rotating screw 402 drives the two driving blocks 5 to move away from each other, changing the forming angle of the two connecting plates 6. The smaller the angle, the farther the moving plate 8 is from the mounting frame 3, and vice versa. When the moving plate 8 is close to the mounting frame 3, the adjusting plate 1 9 and the adjusting plate 2 10 overlap and fold, thereby reducing the overall width of the lifting device. This makes it easier to put the lifting device that suspends the workpiece into the shot blasting machine. After it is put into the shot blasting machine, the handle 401 is turned in the opposite direction to move the moving plate 8 away from the mounting frame 3. The adjusting plate 1 9 and the adjusting plate 2 10 unfold, increasing the distance between the hooks 11 on the adjusting plate 1 9 and the adjusting plate 2 10. Then the workpiece can be shot blasted.
[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
