Description

Technical Field

[0001] The utility model relates to the field of crucible hoisting, in particular to a crucible hoisting clamp. Background Art

[0002] Lithium ion batteries usually use graphite micropowder as the negative electrode material. In the graphitization production process of the negative electrode material, a graphite crucible is used as a container carrier, and a crane and a lifting tool are used to lift the crucible for charging and discharging the furnace. The traditional operation process of lifting the crucible generally uses a high-temperature resistant steel wire rope to tie a slipknot to hold two crucibles. When the crane pulls the steel wire rope upward, the steel wire rope tightens the crucible to achieve the purpose of lifting. This not only has a low lifting efficiency but also a low safety factor, and thus needs to be improved urgently. Content of the Utility Model

[0003] The purpose of the utility model is to provide a crucible hoisting clamp, which is used to solve the problems that the existing crucible hoisting clamp has low lifting efficiency and low safety factor.

[0004] To solve the above problems, the utility model provides a crucible hoisting clamp, which includes a hoisting top plate and a plurality of clamping components hinged to the bottom of the hoisting top plate. Linking rods are connected in series on both sides of the plurality of clamping components. Each clamping component includes a first connecting rod, a second connecting rod, a first clamping arm and a second clamping arm. The top end of the first connecting rod is hinged to the top end of the second connecting rod. The bottom end of the first connecting rod is hinged to the top end of the first clamping arm. The bottom end of the second connecting rod is hinged to the top end of the second clamping arm. The middle parts of the first clamping arm and the second clamping arm are hinged at a point.

[0005] The crucible hoisting clamp provided by the utility model further has the following technical features:

[0006] Further, an auxiliary component is installed between two adjacent clamping components. The auxiliary component includes a rotating hook and a hanging ring plate. The rotating hook rotates around the hinge point of the top ends of the first connecting rod and the second connecting rod. The hanging ring plate is fixed to two adjacent ones. The hanging hole of the hanging ring plate is located directly below the hinge point of the top ends of the first connecting rod and the second connecting rod.

[0007] Further, a handle is fixedly arranged at one end of the rotating hook.

[0008] Further, wear-resistant clamping blocks are fixedly arranged at the bottom ends of the first clamping arm and the second clamping arm. Arc-shaped grooves are symmetrically arranged on the inner side of each wear-resistant clamping block.

[0009] Further, the number of the clamping components below the hoisting top plate is at least 3.

[0010] Further, the extension lines of the bottom ends of the first clamping arm and the second clamping arm intersect at a point.

[0011] The utility model has the following beneficial effects: through the linkage rod, the hinge points of the first connecting rod and the second connecting rod on the same side can be connected in series respectively, ensuring that multiple first clamping arms and second clamping arms clamp the crucible synchronously, improving the clamping efficiency and stability. At the same time, the strength of the whole fixture is also improved, avoiding deformation due to stress when clamping the crucible. Description of the Drawings

[0015] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0016] As Figures 1 to 3 shown in an embodiment of a crucible lifting fixture of the present utility model, it includes a lifting top plate 1 and a plurality of clamping assemblies 2 hinged to the bottom of the lifting top plate 1. Linkage rods 3 are connected in series on both sides of the plurality of clamping assemblies 2. Each clamping assembly 2 includes a first connecting rod 21, a second connecting rod 22, a first clamping arm 23 and a second clamping arm 24. The top end of the first connecting rod 21 is hinged to the top end of the second connecting rod 22. The bottom end of the first connecting rod 21 is hinged to the top end of the first clamping arm 23. The bottom end of the second connecting rod 22 is hinged to the top end of the second clamping arm 24. The middle parts of the first clamping arm 23 and the second clamping arm 24 are hinged at a point. Specifically, through the linkage rod 3, the hinge points of the first connecting rod 21 and the second connecting rod 22 on the same side can be connected in series respectively, ensuring that multiple first clamping arms 23 and second clamping arms 24 clamp the crucible synchronously, improving the clamping efficiency and stability. At the same time, the strength of the whole fixture is also improved, avoiding deformation due to stress when clamping the crucible.

[0017] In one embodiment of the present application, an auxiliary component 4 is installed between two adjacent clamping components 2. The auxiliary component 4 includes a rotating hook 41 and a hanging ring plate 42. The rotating hook 41 uses the top hinge point of the first connecting rod 21 and the second connecting rod 22 as the rotation center. The hanging ring plate 42 is fixed to the two adjacent clamping components 2. The hanging hole 420 of the hanging ring plate 42 is located directly below the top hinge point of the first connecting rod 21 and the second connecting rod 22. Specifically, before clamping, the rotating hook 41 is first moved downward, and the angle between the first connecting rod 21 and the second connecting rod 22 increases. Since the bottom end of the first connecting rod 21 is hinged to the top of the first clamping arm 23, and the bottom end of the second connecting rod 22 is hinged to the top of the second clamping arm 24, the bottom end of the first clamping arm 23 and the bottom end of the second clamping arm 24 are close to each other. When the rotating hook 41 is hooked with the hanging ring hole 420 on the hanging ring plate 42, the first clamping arm 23 and the second clamping arm 24 are maintained at a preset opening and closing angle to avoid closing before the crucible is clamped.

[0018] In one embodiment of the present application, a handle 411 is fixedly provided at one end of the rotating hook 41. Specifically, when the first clamping arm 23 and the second clamping arm 24 descend to a specified clamping position, the handle 411 is rotated to disengage the rotating hook 41 from the hanging ring hole 420 on the hanging ring plate 42. When lifting upward, the bottom end angle between the first clamping arm 23 and the second clamping arm 24 becomes smaller, so as to firmly clamp the outer wall of the crucible 100, and the crucible can be lifted to a suitable position.

[0019] In one embodiment of the present application, a wear-resistant clamping block 5 is fixedly provided at the bottom end of the first clamping arm 23 and the second clamping arm 24, and an arc groove 51 is symmetrically provided on the inner side of each wear-resistant clamping block 5. Specifically, such a design enables each wear-resistant clamping block 5 to clamp two crucibles at the same time, thereby improving the clamping efficiency.

[0020] In one embodiment of the present application, the number of clamping assemblies below the lifting ceiling 1 is at least three.

[0021] In one embodiment of the present application, the bottom end of the first clamping arm 23 and the extended line of the bottom end of the second clamping arm 24 intersect at one point.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
