Description

Technical Field

[0001] This application relates to the field of square crucible technology, and more particularly to a square crucible clamp. Background Technology

[0002] A square crucible is a high-temperature resistant container widely used in the production of graphite and carbon products, lithium battery anode materials, etc. It is mainly used for high-temperature calcination. Specifically, during the high-temperature calcination process, a square crucible containing materials such as graphite and carbon products or lithium battery anode materials needs to be placed into a calcination furnace. After calcination, the square crucible needs to be removed from the calcination furnace. Since the calcination temperature can reach up to 2800℃, the temperature after calcination is high, and the volume and mass of the square crucible are large. Therefore, in the above process, clamps are needed to remove and place the square crucible.

[0003] The existing square crucibles are mainly clamped using the following two methods:

[0004] 1) The square crucible is tied with belts or wires and then lifted by a crane. This method makes the square crucible prone to tilting during the ascent, which may cause the top cover of the square crucible to fall off, allowing air to enter the square crucible and causing oxidation of the product inside, thus reducing the production quality of the product.

[0005] 2) Clamping the square crucible with an adjustable ring. Although this clamping method has high stability, the pressure applied to the square crucible is not easy to control. Specifically, if the pressure applied to the square crucible is too high, it will damage the outer wall of the square crucible, while if the pressure is too low, it will cause the clamping to be unstable.

[0006] Based on this, this application proposes a square crucible clamp. Utility Model Content

[0007] This application provides a square crucible clamp to solve the technical problems described in the background art above.

[0008] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0009] This application provides a square crucible clamp, comprising:

[0010] A horizontal mounting plate, wherein a lifting ring for connecting a lifting device is provided on the upper surface of the horizontal mounting plate, and two first connecting members are provided on its lower surface, the two first connecting members being symmetrical about the central axis of the horizontal mounting plate in the length direction;

[0011] Two clamping assemblies are provided, each corresponding to one of the two first connecting members. Each clamping assembly includes two first clamping arms and two second clamping arms. One end of each of the two first clamping arms is hinged to the first connecting member. The two second clamping arms are cross-hinged through the second connecting member. The top end of each second clamping arm is hinged to the end of the corresponding first clamping arm away from the first connecting member, and its bottom end is provided with a clamping plate for clamping the square crucible.

[0012] Optionally, the two second connectors are connected together by a horizontal connecting plate, wherein a hanging ring is provided in the middle of the upper surface of the horizontal connecting plate;

[0013] A third connector is provided in the middle of the lower surface of the horizontal mounting plate, and a hook for attaching the hanging ring is provided at the bottom end of the third connector.

[0014] Optionally, each of the clamping plates has two concave clamping grooves, each of which is adapted to the square crucible.

[0015] Optionally, the depth of each of the clamping slots is greater than or equal to 85 mm.

[0016] Optionally, a plurality of friction protrusions are uniformly provided on the inner wall of each of the clamping grooves.

[0017] Optionally, each of the second clamping arms includes an integrally formed first clamping plate and a second clamping plate;

[0018] The end of the first clamping plate away from the second clamping plate is hinged to the end of the first clamping arm away from the first connecting member, and the connection between the first clamping plate and the second clamping plate is hinged to the second connecting member;

[0019] The first clamping plate and the second clamping plate form an obtuse angle, and the second clamping plate is L-shaped.

[0020] Optionally, a slot is provided in the middle of the clamping plate, and the bottom end of the second clamping arm is inserted into the slot and connected to the slot by fasteners.

[0021] Optionally, there are at least two lifting rings, which are evenly distributed on the upper surface of the horizontal mounting plate.

[0022] Optionally, the first clamping arm, the second clamping arm, and the clamping plate are all made of high-temperature resistant alloy steel.

[0023] The square crucible clamp provided in this application has a horizontal mounting plate and two first connecting members symmetrical about the central axis of the horizontal mounting plate along its length on the lower surface of the horizontal mounting plate. Each first connecting member is hinged with a clamping assembly. In other words, the two clamping assemblies are symmetrical about the central axis of the horizontal mounting plate along its length. This improves the stability of the two clamping assemblies during the lifting process of the lifting device to lift the horizontal mounting plate, and thus improves the stability of the square crucible clamped by the clamping assemblies. Furthermore, during the lifting process, since the first clamping arm is hinged to the first connecting member, and the second clamping arm is hinged to the first clamping arm, when the clamping plates at the bottom ends of the two second clamping arms are located on opposite sides of the square crucible, the lifting device lifts the crucible upwards, and under the action of gravity, the two second clamping arms move closer to each other. This causes the clamping plates at the bottom ends of the second clamping arms to gradually approach the outer wall of the square crucible and clamp the crucible. When the square crucible is lifted to the desired placement position, the lifting device moves downwards, causing the distance between the first and second clamping arms to gradually decrease, thus moving the clamping plates away from the outer wall of the square crucible. At this time, the clamping assembly is separated from the square crucible by moving the horizontal mounting plate horizontally through the lifting device. Therefore, compared with existing square crucible clamping methods, this application makes the square crucible more stable during the clamping process, thereby improving the safety of the square crucible lifting process. Furthermore, by raising or lowering the horizontal mounting plate through the lifting device, the clamping plate can be clamped or released from the square crucible, thereby improving the convenience of clamping the square crucible.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0032] refer to Figures 1 to 5 This application provides a square crucible clamp, comprising:

[0033] A horizontal mounting plate 100 has a lifting ring 101 for connecting a lifting device on its upper surface and two first connecting members 102 on its lower surface. The two first connecting members 102 are symmetrical about the central axis of the horizontal mounting plate 100 along its length. The lifting device can be a crane, and one end of the lifting device is equipped with a hook adapted to the lifting ring 101. The lifting ring 101 facilitates lifting by the lifting device. Each first connecting member 102 may include, but is not limited to, two first connecting plates and a first hinge shaft. The two first connecting plates can be welded to each other on the lower surface of the horizontal mounting plate 100, and the first hinge shaft passes through the two first connecting plates and is movably connected to the two first connecting plates (see [reference]). Figure 2 ).

[0034] Two clamping assemblies 200 are provided, each corresponding to one of the two first connecting members 102. Each clamping assembly 200 includes two first clamping arms 201 and two second clamping arms 202. One end of each of the two first clamping arms 201 is hinged to the first connecting member 102. The two second clamping arms 202 are cross-hinged through the second connecting member 300. The top end of each second clamping arm 202 is hinged to the end of its corresponding first clamping arm 201 away from the first connecting member 102, and its bottom end is provided with a clamping plate 500 for clamping the square crucible 400. Since the two first connecting members 102 are symmetrical about the central axis of the horizontal mounting plate 100 along its length, and the two clamping assemblies 200 are respectively hinged to their corresponding first connecting members 102, the symmetry of the two clamping assemblies 200 about the central axis of the horizontal mounting plate 100 ensures high stability of the square crucible 400 during the lifting or lowering of the horizontal mounting plate 100 by the lifting device. This minimizes the risk of the square crucible 400 tilting, which could cause the top cover of the square crucible 400 to fall off, allowing air to enter the square crucible 400 and causing oxidation of the product inside, thus reducing the production quality. Furthermore, both first clamping arms 201 are sleeved on the first hinge shaft included in the first connecting member 102. The structure of the second connecting member 300 can be referenced from the structure of the first connecting member 102, and will not be described in detail here.

[0035] The square crucible clamp provided in this application has a horizontal mounting plate 100 and two first connecting members 102 that are symmetrical about the central axis of the horizontal mounting plate 100 in the length direction on the lower surface of the horizontal mounting plate 100. Each first connecting member 102 is hinged with a clamping assembly 200. That is, the two clamping assemblies 200 are symmetrical about the central axis of the horizontal mounting plate 100 in the length direction. This improves the stability of the two clamping assemblies 200 during the lifting process of the lifting device lifting the horizontal mounting plate 100, and thus improves the stability of the square crucible 400 clamped by the clamping assembly 200. Furthermore, during the lifting process, since the first clamping arm 201 is hinged to the first connecting member 102, and the second clamping arm 202 is hinged to the first clamping arm 201, when the clamping plates 500 at the bottom of the two second clamping arms 202 are respectively located on opposite sides of the square crucible 400, the lifting device lifts the two second clamping arms 202 closer to each other under the action of gravity, thereby causing the clamping plates 500 at the bottom of the second clamping arms 202 to gradually approach the outer wall of the square crucible 400 and clamp the square crucible 400. When the square crucible 400 is lifted to the desired placement position, the lifting device moves downward, causing the distance between the first clamping arm 201 and the second clamping arm 202 to gradually decrease, causing the clamping plates 500 to move away from the outer wall of the square crucible 400. At this time, the clamping assembly 200 and the square crucible 400 are separated by moving the horizontal mounting plate 100 horizontally through the lifting device. Therefore, compared with the existing clamping method of the square crucible 400, this application makes the square crucible 400 more stable during the clamping process, thereby improving the safety of the lifting process of the square crucible 400. Furthermore, by raising or lowering the horizontal mounting plate 100 through the lifting device, the clamping plate 500 can clamp or release the square crucible 400, thereby improving the convenience of clamping the square crucible 400.

[0036] In some embodiments, reference Figure 1 and Figure 2 In this application, the two second connecting members 300 are connected together by a horizontal connecting plate 600. A hanging ring 601 is provided in the middle of the upper surface of the horizontal connecting plate 600. The two ends of the horizontal connecting plate 600 along its length direction are fixedly connected to the second connecting members 300. The structure of the second connecting member 300 can be referred to the structure of the first connecting member 102 given above, and will not be repeated here.

[0037] Additionally, a third connector 700 is provided at the center of the lower surface of the horizontal mounting plate 100, and a hook 701 for attaching a hanging ring 601 is provided at the bottom end of the third connector 700. The third connector 700 includes, but is not limited to, two connecting plates, one end of which is hinged to the lower surface of the horizontal mounting plate 100 and the other end of which is hinged to one end of the other connecting plate. The hook 701 is located at the other end of the other connecting plate (see reference). Figure 1and Figure 2 ).

[0038] In the above embodiments, if the distance between the two clamping plates 500 is less than the length or width of the square crucible 400 before clamping the square crucible 400 by the two clamping plates 500, then external force is needed to pull the distance between the two clamping plates 500 apart so that the distance between them is greater than the length or width of the square crucible 400. The above operation will reduce the clamping efficiency of the square crucible 400. In addition, the first clamping arm 201, the second clamping arm 202 and the clamping plate 500 all have a large weight, making it more difficult to pull the two clamping plates 500 apart by external force. The present application, through the arrangement of the third connector 700, hook 701, horizontal connecting plate 600 and hanging ring 601, ensures that when the outer bottom surface of the square crucible 400 is lowered to the required placement position by the lifting device, the lifting device stops lowering and simultaneously hooks the hook 701 onto the hanging ring 601. This prevents the distance between the two clamping plates 500 corresponding to the square crucible 400 from decreasing as the lifting device moves, facilitating the clamping of the square crucible 400 for the next time.

[0039] In some embodiments, reference Figure 5 In this application, each clamping plate 500 has two concave clamping grooves 501, each clamping groove 501 is adapted to the square crucible 400, so that each clamping component 200 corresponds to two square crucibles 400, and two clamping components 200 correspond to four square crucibles 400. That is, four square crucibles 400 can be lifted at the same time by the lifting device, thereby improving the clamping efficiency of the square crucibles 400.

[0040] In some embodiments, reference Figure 4 In this application, each clamping groove 501 has a plurality of friction protrusions 5011 evenly arranged on its inner wall. These friction protrusions 5011 can be spherical, strip-shaped, etc., and can be specifically designed according to actual conditions; however, this application does not impose any specific limitations on them. Furthermore, Figure 4 The image shows a spherical friction protrusion 5011.

[0041] In the above embodiment, the friction protrusion 5011 is welded to the inner wall of the clamping groove 501. The setting of the friction protrusion 5011 increases the friction between the inner wall of the clamping groove 501 and the outer wall of the square crucible 400, making the clamping process of the clamping plate 500 on the square crucible 400 more stable.

[0042] In some embodiments, reference Figure 3Each second clamping arm 202 in this application includes an integrally formed first clamping plate 2021 and a second clamping plate 2022. Specifically, the end of the first clamping plate 2021 away from the second clamping plate 2022 is hinged to the end of the first clamping arm 201 away from the first connector 102, and the connection between the first clamping plate 2021 and the second clamping plate 2022 is hinged to the second connector 300. This enables the two second clamping arms 202 to be cross-hinged, which facilitates the opening and closing of the clamping plate 500 to clamp or release the other crucible 400.

[0043] The first clamping plate 2021 and the second clamping plate 2022 form an obtuse angle, which facilitates the cross-hinged connection between the two second clamping arms 202. The second clamping plate 2022 is L-shaped, which makes it more compatible with the square crucible 400 and facilitates the clamping of the square crucible 400.

[0044] In some embodiments, reference Figure 5 In this application, the clamping plate 500 has a slot 502 in its middle. The bottom end of the second clamping arm 202 is inserted into the slot 502 and connected to the slot 502 by a fastener 800. The fastener 800 can be a bolt or a nut. When the fastener 800 is a bolt or a nut, threaded through holes adapted to the bolt are provided on the opposite side walls of the slot 502. Specifically, the bolt end passes through the two threaded through holes in sequence, and then the nut is screwed onto the bolt. This achieves a fixed connection between the second clamping arm 202 and the slot 502, thereby improving the stability of the connection between the second clamping arm 202 and the slot 502.

[0045] In the above embodiments, the method of connecting the bottom end of the second clamping arm 202 to the slot 502 by fastener 800 facilitates installation and makes it easy to disassemble when replacing the clamping plate 500, thereby improving the convenience of installing or disassembling the clamping plate 500.

[0046] In some embodiments, reference Figure 1 and Figure 2 In this application, there are at least two lifting rings 101, which are evenly distributed on the upper surface of the horizontal mounting plate 100.

[0047] In the above embodiments, since the horizontal mounting plate 100, the first clamping arm 201, the second clamping arm 202, the clamping plate 500, and the square crucible 400 all have a certain weight, in order to improve the stability of the horizontal mounting plate 100, the first clamping arm 201, the second clamping arm 202, the clamping plate 500, and the square crucible 400 during the lifting process, at least two lifting rings 101 can be provided. Specifically, when there are two lifting rings 101, the two lifting rings 101 are symmetrical about the central axis of the length direction of the horizontal mounting plate 100, that is, the lifting device has multiple force points, which can avoid localized stress, thereby improving the stability of the horizontal mounting plate 100, the first clamping arm 201, the second clamping arm 202, the clamping plate 500, and the square crucible 400 during the lifting process. The number of lifting rings 101 can be set according to the actual situation, and this application will not make specific limitations on it here.

[0048] In some embodiments, the first clamping arm 201, the second clamping arm 202, and the clamping plate 500 in this application are all made of high-temperature resistant alloy steel.

[0049] In the above embodiments, the main components of alloy steel, in addition to iron and carbon, include other alloying elements, and it has advantages such as high strength and toughness, wear resistance and fatigue resistance, corrosion resistance and high temperature resistance. Since the square crucible 400 is mainly used for high-temperature calcination, the first clamping arm 201, the second clamping arm 202 and the clamping plate 500 made of alloy steel have high durability in the process of clamping the square crucible 400, giving it a long service life.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
