Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting technology, specifically to a hoisting fixture for hydraulic support column sockets. Background Technology
[0002] The hydraulic support column socket is a crucial component, typically requiring tilting during hoisting into the space between the inner and outer main ribs of the base. The existing hoisting method involves using an electro-permanent magnet to hold one side of the socket, then lifting it using a semi-gantry crane. Because the center of gravity of the socket and the hoisting force are not aligned vertically, the socket tilts precisely into the base during hoisting, bypassing the obstruction of the base's process supports. However, the irregular surface of the socket results in a small contact area between the electro-permanent magnet and the socket. Furthermore, the large size and weight of the workpiece cause tilting and swaying during hoisting, leading to weak magnet adhesion and easy detachment, thus reducing safety.
[0003] Chinese utility model patent CN2017210901130 discloses a lifting device for processing hydraulic support column sockets and caps. It includes a hook device mounted on the upper end face of the column socket or cap, and fastening bolts connected to the hook device and acting on the side of the column socket or cap. The hook device forms a clamping support for the side of the column socket or cap, and the fastening bolts clamp the side of the column socket or cap. This eliminates the need for magnetic chucks and rope-type lifting devices, thus improving lifting safety and ensuring the clamping requirements for processing the column socket and cap. However, this lifting device relies on fastening bolts to clamp the workpiece, requiring frequent tightening and loosening of the bolts, making operation cumbersome. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a tooling for lifting hydraulic support column sockets.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lifting fixture for hydraulic support column sockets, comprising an L-shaped left jaw and a right jaw; the left end of the upper horizontal beam of the left jaw is integrally formed and fixedly connected to the upper end of the left vertical beam, and the right end of the upper horizontal beam of the right jaw is integrally formed and fixedly connected to the upper end of the right vertical beam; a left clamping member is provided at the lower end of the left vertical beam of the left jaw, and a right clamping member is provided at the lower end of the right vertical beam of the right jaw; the upper horizontal beam of the right jaw is positioned below the upper horizontal beam of the left jaw, and the left end of the upper horizontal beam of the right jaw is hinged to the left vertical beam of the left jaw; a lifting ring is provided at the right end of the upper horizontal beam of the left jaw; an adjusting plate is slidably connected to the upper horizontal beam of the right jaw, and an adjusting elongated hole is vertically opened at the upper part of the adjusting plate, through which the upper horizontal beam of the left jaw passes.
[0006] Based on the above, the left clamping member includes a first circular clamping plate, which is disposed on the right side of the lower end of the left vertical beam of the left jaw; The right clamping member includes a clamping beam, which is horizontally positioned at the front and rear of the right vertical beam directly below the right vertical beam of the right jaw. The upper middle part of the clamping beam is fixedly connected to the lower end of the right vertical beam of the right jaw. A second circular clamping plate is provided on the left side of both ends of the clamping beam. When clamping a workpiece, the first circular clamping plate and the two second circular clamping plates are in contact with the workpiece.
[0007] Based on the above, the left jaw, the right jaw, and the clamping beam are all steel pipe structures.
[0008] This utility model has substantial features and advancements compared to existing technologies. Specifically, it features an L-shaped left and right chuck. The upper crossbeam of the right chuck is hinged to the left vertical beam of the left chuck, and an adjusting plate is slidably connected to the upper crossbeam of the right chuck. An adjusting elongated hole is vertically formed at the top of the adjusting plate, and the upper crossbeam of the left chuck passes through this hole. In use, by adjusting the position of the adjusting plate on the upper crossbeam of the right chuck, the upper crossbeam of the left chuck is adjusted accordingly. The vertical swing amplitude in the elongated hole; when it is necessary to lift the workpiece, the left clamp and the right clamp are clamped on both sides of the workpiece, and then the adjusting plate is moved to the left end of the upper crossbeam of the right jaw. Then the vertical swing amplitude of the upper crossbeam of the left jaw in the adjusting elongated hole is adjusted to the maximum. At this time, the minimum opening distance between the left clamp and the right clamp is less than the size of the workpiece. The lifting ring is lifted by a crane, and the left jaw rotates to the lower right under its own weight around the lifting ring. At the same time, the right jaw rotates around its left jaw under its own weight. The hinge point rotates downwards to the left, causing the left and right jaws to close under gravity, clamping the workpiece. Since the lifting ring is located at the right end of the upper crossbeam of the left jaw, and there is friction between the left and right clamping members and the workpiece, the left and right jaws are tilted when clamping the workpiece, forming a self-locking mechanism through pressure contact. This ensures a secure and reliable clamping of the workpiece, high safety, and simple operation. Furthermore, the tilted workpiece is not affected by the base's process support. The system provides a support and blocking mechanism. When the workpiece is hoisted, the adjusting plate is moved to the right end of the upper crossbeam of the right jaw. The adjusting plate then approaches the lifting ring, and the upper crossbeam of the left jaw swings to its minimum amplitude in the adjusting elongated hole. At this time, the minimum opening distance between the left and right clamping parts is greater than the workpiece size, causing the left and right clamping parts to release the workpiece. The lifting ring is then lifted by a crane, allowing the left and right jaws to be lifted away from the workpiece. The operation is simple, convenient, quick, time-saving, labor-saving, and highly efficient.
[0009] Furthermore, the left clamping member includes a first circular clamping plate, and the right clamping member includes two second circular clamping plates. When clamping the workpiece, the first circular clamping plate and the two second circular clamping plates are in contact with the workpiece together, forming a three-point gripping method to achieve stable clamping of the workpiece.
[0010] Furthermore, the left jaw, the right jaw, and the clamping beam are all steel pipe structures, which are lightweight.
[0011] In summary, this utility model provides a firm and reliable clamping of the workpiece, ensuring high safety, and is simple, convenient, quick, time-saving, labor-saving, and highly efficient. Attached Figure Description

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments.
[0018] like Figures 1-4 As shown, a lifting fixture for hydraulic support column sockets includes an L-shaped left jaw 1 and a right jaw 2. The left end of the upper horizontal beam of the left jaw 1 is integrally formed and fixedly connected to the upper end of the left vertical beam, and the right end of the upper horizontal beam of the right jaw 2 is integrally formed and fixedly connected to the upper end of the right vertical beam. A left clamping member is provided at the lower end of the left vertical beam of the left jaw 1, and a right clamping member is provided at the lower end of the right vertical beam of the right jaw 2. The upper horizontal beam of the right jaw 2 is placed below the upper horizontal beam of the left jaw 1, and the left end of the upper horizontal beam of the right jaw 2 is hinged to the left vertical beam of the left jaw 1. A lifting ring 3 is provided at the right end of the upper horizontal beam of the left jaw 1. An adjusting plate 4 is slidably connected to the upper horizontal beam of the right jaw 2, and an adjusting elongated hole 5 is vertically opened at the upper part of the adjusting plate 4, through which the upper horizontal beam of the left jaw 1 passes.
[0019] The left clamping member includes a first circular clamping plate 6, which is disposed on the right side of the lower end of the left vertical beam of the left claw 1; The right clamping member includes a clamping beam 7, which is horizontally positioned at the front and rear of the right claw 2 directly below the right vertical beam. The upper middle part of the clamping beam 7 is fixedly connected to the lower end of the right vertical beam of the right claw 2. A second circular clamping plate 8 is provided on the left side of both ends of the clamping beam 7. When clamping the workpiece, the first circular clamping plate 6 and the two second circular clamping plates 8 are in contact with the workpiece.
[0020] The left jaw 1, the right jaw 2, and the clamping beam 7 are all steel pipe structures.
[0021] In other embodiments, the left jaw 1, the right jaw 2, and the clamping beam 7 may also be plate structures.
[0022] In use, this invention adjusts the position of the adjusting plate 4 on the upper crossbeam of the right jaw 2, thereby adjusting the vertical swing amplitude of the upper crossbeam of the left jaw 1 in the adjusting elongated hole 5. When lifting a workpiece, the left and right clamping parts are clamped on both sides of the workpiece, and then the adjusting plate 4 is moved to the left end of the upper crossbeam of the right jaw 2. The vertical swing amplitude of the upper crossbeam of the left jaw 1 in the adjusting elongated hole 5 is then maximized. At this time, the minimum opening distance between the left and right clamping parts can be less than the workpiece size. When the lifting ring 3 is lifted by a crane, the left jaw 1 rotates to the lower right under its own weight around the lifting ring 3, while the right jaw 2 rotates to the lower left under its own weight around its hinge point with the left jaw 1. Thus, the left and right jaws close under gravity, clamping the workpiece. Since the lifting ring 3 is located at the... The left jaw 1 is located at the right end of the upper crossbeam, and there is friction between the left and right clamping members and the workpiece. Therefore, when the left jaw 1 and the right jaw 2 clamp the workpiece, they are in an inclined state and press against the workpiece to form a self-locking mechanism, achieving a firm and reliable clamping of the workpiece with high safety and simple operation. The workpiece is inclined and will not be blocked by the process support of the base. When the workpiece is hoisted, the adjusting plate 4 is moved to the right end of the upper crossbeam of the right jaw 2. The adjusting plate 4 is then close to the lifting ring 3, and the vertical swing amplitude of the upper crossbeam of the left jaw 1 in the adjusting elongated hole 5 is adjusted to the minimum. At this time, the minimum opening distance of the left and right clamping members is greater than the size of the workpiece, and the left and right clamping members release the workpiece. The lifting ring 3 is then lifted by a crane, and the left jaw 1 and the right jaw 2 can be lifted away and detached from the workpiece. The operation is simple, convenient, quick, time-saving, labor-saving, and highly efficient.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
