Description

Technical Field

[0001] The utility model belongs to the technical field of tooling fixtures, and particularly relates to a lifting fixture. Background Art

[0002] Carbon electrode generally refers to an electrode composed of elemental carbon. It can be divided into four categories: natural graphite electrode, artificial graphite electrode, carbon electrode, and special carbon electrode.

[0003] According to actual usage requirements, carbon electrodes have various different shapes. The cylindrical shape is a commonly used shape for carbon electrodes. According to actual usage requirements, cylindrical carbon electrodes with various different diameters or lengths can be produced. When the produced cylindrical carbon electrode is relatively large, a lifting fixture is usually used to clamp the cylindrical carbon electrode for movement.

[0004] The Chinese utility model patent "A Special Tooling for Lifting Cylinders" with the publication number CN217921066U discloses the following: including a tooling fixture, a lifting frame is arranged on the outer surface of the upper end of the tooling fixture, a shaft pin is arranged in the middle of the lifting frame, an iron plate is arranged on the outer surface of one end of the lifting frame, a hinge is arranged on the outer surface of one side of the iron plate, a snap ring is arranged on the outer surface of one end of the hinge, and the number of the tooling fixture, the lifting frame, and the iron plate is two groups. The outer surfaces of the upper ends of the two groups of tooling fixtures are fixedly connected to the outer surface of one end of the lifting frame.

[0005] When the tooling of the above patent is used, it can only lift one cylinder, with a low lifting efficiency, which will increase the lifting frequency and reduce the lifting efficiency of the cylinder.

[0006] Therefore, a lifting fixture is urgently needed to solve the above technical problems. Summary of the Utility Model

[0007] The purpose of the utility model is to overcome the existing technical problems and provide a lifting fixture.

[0008] To achieve the above purpose, the utility model is implemented according to the following technical solution:

[0009] The lifting fixture includes a frame, and a lifting component and a clamping component installed on the frame; the frame includes a clamping installation frame and a lifting installation frame;

[0010] The clamping installation frame includes two installation cross plates and several connecting plates A; the two installation cross plates are symmetrically arranged front and back, and the lower end surfaces of the two installation cross plates are fixedly connected by several connecting plates A;

[0011] The hoisting and installation frame includes two U-shaped plates, two connecting plates B, and two partition plates; the two U-shaped plates have their openings facing downwards and are symmetrically and fixedly installed on the upper end surface of the installation cross plate in the front and back; the upper parts between the opposite end faces of the two U-shaped plates are fixedly connected by two connecting plates B, and the two connecting plates B are symmetrically arranged on the left and right; a partition plate is fixedly arranged on the front side and the rear side of the opposite end faces of the two connecting plates B, and the two partition plates are symmetrically arranged in the front and back; a rectangular channel A is formed among the partition plate on the front side, the U-shaped plate on the front side, and the two connecting plates B; a rectangular channel B is formed among the partition plate on the rear side, the U-shaped plate on the rear side, and the two connecting plates B;

[0012] The hoisting assembly includes two moving plates, a connecting plate C, and a hoisting plate; the two moving plates are vertically and symmetrically arranged in the front and back in the channels A and B respectively; the heads of the two moving plates are fixedly connected by the connecting plate C, the hoisting plate is fixedly arranged on the upper end surface of the connecting plate C, and a hoisting hole is arranged on the hoisting plate;

[0013] The clamping assembly includes a left clamping member and a right clamping member which are identical in structure and symmetrically arranged on the left and right; the left clamping member includes two clamping arms and two connecting arms which are symmetrically arranged in the front and back, and also includes a mounting plate and a clamping plate;

[0014] The clamping arm is an integral structure and includes a clamping section A and a clamping section B which are sequentially connected from top to bottom, and there is an obtuse angle between the clamping section A and the clamping section B;

[0015] The head of the clamping section A on the front side is hinged to the tail of the connecting arm on the front side, and the head of the connecting arm on the front side is hinged to the left side of the lower end of the moving plate on the front side; the head of the clamping section A on the rear side is hinged to the tail of the connecting arm on the rear side, and the head of the connecting arm on the rear side is hinged to the left side of the lower end of the moving plate on the rear side;

[0016] The transition part between the clamping section A and the clamping section B on the front side is hinged to the left end of the front mounting cross plate; the transition part between the clamping section A and the clamping section B on the rear side is hinged to the left end of the rear mounting cross plate;

[0017] The two clamping sections B are fixedly connected by the mounting plate; the clamping plate is detachably installed on the right side of the mounting plate; several support columns A are fixedly arranged at equal distances from front to back on the lower part of the right side of the clamping plate.

[0018] In the present utility model, the ways of hinging and fixed connection are all selected from the prior art, and those skilled in the art can choose according to actual usage requirements. Specifically, the hinging can be realized by a hinge shaft or other parts for hinging, and the fixed connection can be realized by welding.

[0019] When the utility model is in use, the hook can be sleeved into the lifting hole, and the lifting fixture is moved above the cylindrical carbon electrode to be lifted, and then slowly lowered. Then, the left clamping member and the right clamping member are opened, and the clamping plates on both sides are respectively located at both ends of the cylindrical carbon electrode. Subsequently, the end of the cylindrical carbon electrode is placed above the space between the adjacent support columns A. Then, the lifting fixture is lifted. Under the action of gravity, the left clamping member and the right clamping member are closed, and the clamping plates on both sides are respectively in contact with both ends of the cylindrical carbon electrode, and the support columns A on both sides support the cylindrical carbon electrode. At this time, the cylindrical carbon electrode is clamped and can be lifted to other positions by the lifting fixture.

[0020] At the position between the adjacent support columns A, the opening and closing sizes of the left clamping member and the right clamping member are matched with the diameter and length of the cylindrical carbon electrode to be lifted. The specific dimensions are not limited here again, as long as they can meet the requirements of lifting and moving the cylindrical carbon electrode.

[0021] Preferably, the two clamping sections A are fixedly connected by a channel steel.

[0023] Preferably, several support columns B are fixedly arranged at equal intervals from front to back on the upper part of the left side of the clamping plate.

[0024] Specifically, the distance between adjacent support columns B is different from the distance between adjacent support columns A. This setting is to make the clamping plate more flexible to use and be able to clamp cylindrical carbon electrodes with more different diameters.

[0025] Preferably, a limiting assembly is further arranged on the frame; the limiting assembly includes a left limiting member and a right limiting member; the left limiting member and the right limiting member have the same structure and are symmetrically arranged left and right;

[0026] The left limiting member includes a limiting plate, two lifting rods, two mounting sleeves, and two limiting bolts; the two mounting sleeves are respectively vertically mounted symmetrically front and back on the outer sides of the two mounting cross plates; through hole A is provided on the mounting sleeve; the two lifting rods are respectively inserted into the two mounting sleeves, and several through holes B are arranged at equal intervals on the lifting rods; the lower ends of the two lifting rods are fixedly connected by the limiting plate; the lifting rods are fixedly connected to the mounting sleeves by the limiting bolts.

[0027] The setting of the limiting component makes the clamping and hoisting of the cylindrical carbon electrode more stable. Specifically, when the left clamping piece and the right clamping piece clamp the cylindrical carbon electrode, the limiting plate is adjusted downward so that the limiting plate approaches or contacts the cylindrical carbon electrode. Under the limitation of the left clamping piece, the right clamping piece and the limiting plate, it is avoided that the left clamping piece and the right clamping piece over-clamp and cause the cylindrical carbon electrode to warp. At the same time, the cylindrical carbon electrode is clamped more firmly, which is convenient for hoisting. The length of the limiting plate is also set according to the actual hoisting requirements, and no further limitation is imposed here.

[0028] Components not defined in the present utility model all adopt conventional means in the art. Those skilled in the art can select their models and installation methods according to actual usage requirements, and clearly understand how to install and control them specifically. No detailed description will be given here.

[0030] The structure of the present utility model is simple and the operation is convenient; the hoisting fixture of the present utility model can hoist multiple cylindrical carbon electrodes at the same time, and the hoisting efficiency is high; and there are support column A and support column B, which can be applicable to the hoisting of cylindrical carbon electrodes of various different specifications, and the use is more flexible.
