Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine and tooling technology, specifically to a hanging device. Background Technology

[0002] Large shot blasting machines are primarily designed for larger and longer workpieces. These workpieces are bulky and heavy, and are typically moved in and out of the shot blasting chamber on a shot blasting platform. However, this method creates blind spots, and the bearing contact surface cannot be effectively cleaned, often requiring multiple shot blasting operations. To ensure that the workpiece is completely shot blasted in a single pass, a separate hoisting fixture is needed for transport and lifting. However, existing hoisting fixtures cannot meet the requirements for hoisting and shot blasting operations on such heavy workpieces, thus increasing production costs and reducing shot blasting efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the existing technology and provide a hanging device.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a suspension device, which is mounted on a crane hook, includes a suspension seat, a detachable pin, a hook connecting rod, and a hook. The suspension seat includes a base plate and two vertical plates, which are fixed perpendicularly to the base plate and symmetrically spaced apart. The upper part of the two vertical plates is provided with a horizontally penetrating pin hole, and the pin is detachably installed laterally into the corresponding pin hole. The top end of the hook connecting rod is connected to the center position of the suspension seat base plate, and the bottom end is fixedly installed with a hook. A gear disk is coaxially fixed on the hook connecting rod.

[0005] Furthermore, the aforementioned crane hook is shaped like an anchor and has a double hook configuration; correspondingly, the aforementioned vertical plate is provided with two pin holes, through which a detachable pin passes laterally and is attached to the double hook of the crane hook.

[0006] Furthermore, a connecting through hole is provided at the center of the bottom plate of the suspension seat, the top end of the hook connecting rod passes through the connecting through hole upward, and an external thread is provided on its outer side wall, and a nut is coaxially fitted for threaded fixation; a cover plate is fixedly installed on the top end of the hook connecting rod by bolts, and the diameter of the cover plate is larger than the diameter of the nut.

[0007] Furthermore, the hook connecting rod is rotatably connected to the suspension seat base plate, and a bearing is coaxially sleeved between the two.

[0008] Furthermore, the portion of the hook connecting rod located below the gear disc is thickened.

[0009] Furthermore, the gear disc on the hook connecting rod meshes with the gear of the drive mechanism installed in the shot blasting chamber, which can drive the entire hanging device to rotate, achieving 360° shot blasting operation without dead angles.

[0010] Compared with the prior art, the present invention has the following advantages: The present invention has a simple structure, can effectively lift large-volume and heavy workpieces for shot blasting, realize single full shot blasting, avoid cleaning dead corners, reduce production costs, and improve shot blasting efficiency.

[0016] It should be noted that in the description of this utility model, terms such as "upper", "lower", "left", "right", "inner", "outer", "coaxial", and "center" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are only used to facilitate the description of the structural relationship between the components in this utility model and do not specifically mean that any component in this utility model must have a specific orientation or be constructed and operated in a specific orientation. They should not be construed as limitations on this utility model.

[0017] Furthermore, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0019] like Figures 1 to 4As shown, a lifting device is used for lifting large workpieces with large volume and weight. It is applied to a 120T overhead crane hook 9 and includes a suspension seat 1, a detachable pin 2, a hook connecting rod 3, and a hook 4. The suspension seat 1 includes a base plate 11 and two vertical plates 12. The lower parts of the two vertical plates 12 are fixedly connected to the base plate 11 and are located on the left and right sides of the base plate 11, symmetrically spaced and perpendicular to the base plate 11. The upper parts of the two vertical plates 12 are provided with two horizontally penetrating pin holes at the same level. Correspondingly, the overhead crane hook 9 is anchor-shaped and has a double hook form. When used for lifting, the overhead crane hook 9 is placed in the space between the two vertical plates 12. There are two pins 2, which pass horizontally through the corresponding pin holes. The other end of each pin passes through the opposite vertical plate 12 and is fixed by a set bolt pin. The pins 2 are placed in the hook of the overhead crane hook 9.

[0020] A connecting through hole is provided at the center of the base plate 11 of the suspension seat 1. The upper end of the hook connecting rod 3 passes through the connecting through hole from bottom to top and extends upwards. External threads are provided on its outer side wall. A nut 6 is then coaxially threadedly connected to the upper end of the hook connecting rod 3 to securely connect the hook connecting rod 3 and the suspension seat 1. A through hole is also provided on the side wall of the nut 6 to effectively prevent loosening of the threaded connection caused by resonance. A cover plate 7 is installed at the top of the hook connecting rod 3 and is fixed to it with two bolts 8. The outer diameter of the cover plate 7 is slightly larger than the outer diameter of the nut 6 to limit the nut 6 and prevent it from rotating and detaching. A 100T hook 4 is fixedly installed at the lower end of the hook connecting rod 3. The hook 4 has an anchor-shaped structure and is a double-hook design. An anti-disengagement structure is installed at the opening of each hook to prevent the suspended component from falling off and improve its safety performance. A gear disk 5 is coaxially fixed to the hook connecting rod 3. The gear disk 5 can mesh with the drive gear of the drive mechanism in the shot blasting chamber. When entering the shot blasting chamber for shot blasting operations, the meshing transmission between the drive mechanism and the gear disk 5 can drive the entire hanging device to rotate 360° around the existing connecting structure above the crane hook 9, achieving all-round, no-dead-angle shot blasting operations. Furthermore, the portion of the hook connecting rod 3 located below the fixed position of the gear disk 5 is thickened to avoid wear during shot blasting.

[0021] As another optimized technical solution of this utility model, a bearing is coaxially fixed at the connection between the hook connecting rod 3 and the bottom plate 11 of the suspension seat 1. The outer ring of the bearing is interference-fitted to the bottom plate 11 of the suspension seat, and the inner ring of the bearing is interference-fitted to the hook connecting rod 3. When the drive mechanism in the shot blasting chamber drives the gear disk 5 to rotate, the hook connecting rod 3 can rotate with the suspension seat 1, thereby driving the workpiece to be processed to rotate.

[0022] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
