Description

Technical Field

[0001] This utility model belongs to the technical field of crucible clamping devices, specifically relating to a round crucible clamp. Background Technology

[0002] A round crucible is a vessel or melting pot made of refractory material. It is necessary to use a crucible when a solid needs to be heated over a high flame because it can withstand high temperatures. Its main uses include: evaporation, concentration, or crystallization of solutions; or calcination of solid substances.

[0003] Existing crucible clamps, such as those in prior art CN2020208769959, can only achieve the function of fixing and clamping a single crucible. However, the existing crucible heating process often involves centralized heating of multiple crucibles (such as in a large closed furnace), making it difficult to adapt to the needs of clamping and transferring multiple or double-row crucibles. Utility Model Content

[0004] This application proposes a circular crucible clamp that can clamp and fix multiple circular crucibles in two rows, which is beneficial to improving the transfer efficiency of crucibles after heating.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A circular crucible clamp includes two clamping parts, the tops of which are connected by a crossbar. Each clamping part includes two first connecting rods and two second connecting rods. One end of each of the first connecting rods is rotatably connected to a first pivot at the bottom of the crossbar. The second connecting rods are bent and one end of each of the second connecting rods is rotatably connected to the other end of each of the first connecting rods via a second pivot. The other end of each second connecting rod is provided with a first clamping block. A semi-circular groove is provided on one side of each first clamping block that is close to the other. The bodies of the two second connecting rods are rotatably connected by a third pivot. The third pivots of the two clamping parts are connected by a beam. A connecting column is provided at the bottom of the beam. A second clamping block is provided at the bottom of the connecting column. Semi-circular grooves are provided on both sides of the second clamping block.

[0007] In one embodiment of this application, the first link and the second link are configured with double-layer clamps.

[0008] In one embodiment of this application, a reinforcing plate is provided between the double-layered clamps of the second link.

[0009] In one embodiment of this application, a safety chain is provided between the crossbar and the beam.

[0010] In one embodiment of this application, the inner surfaces of the semi-circular slots of the first clamping block and the second clamping block are provided with groove patterns.

[0011] In one embodiment of this application, the connection between the second connecting rod and the first clamping block, and the connection between the connecting column and the second clamping block, is a detachable connection.

[0012] In one embodiment of this application, a hanging ring is installed on the upper end face of the crossbar.

[0013] In summary, the technical solution proposed in this application includes the following beneficial technical effects: This application moves the first connecting rod by pulling up the crossbar, which in turn causes the second connecting rod to move the first clamping block closer to the second clamping block, so that the semi-circular slots of the first clamping block and the semi-circular slots of the second clamping block clamp and engage with each other, thereby achieving the clamping of the round crucible. By having the semi-circular slots on both sides of the second clamping block engage with the first clamping blocks on both sides of the second clamping block respectively, it is possible to clamp and fix multiple round crucibles in two rows, which is beneficial to improving the efficiency of crucible clamping and transfer after heating.

[0028] This embodiment provides a circular crucible clamp, see reference. Figures 1-5As shown, the device includes two clamping parts 1, the tops of which are connected by a crossbar 2. Each clamping part 1 includes two first connecting rods 11 and two second connecting rods 12. One end of each of the first connecting rods 11 is rotatably connected to a first pivot 111 at the bottom of the crossbar 2. The second connecting rods 12 are bent. One end of each of the second connecting rods 12 is rotatably connected to the other end of each of the first connecting rods 11 via a second pivot 121. The other end of each of the second connecting rods 12 is provided with a first clamping block 122. The sides of the first clamping blocks 122 that are close to each other are provided with a semi-circular groove. The bodies of the two second connecting rods 12 are rotatably connected by a third pivot 123. The third pivot 123 of the two clamping parts 1 are connected by a beam 3. The bottom end of the beam 3 is provided with a connecting post 31. The bottom end of the connecting post 31 is provided with a second clamping block 311. The two sides of the second clamping block 311 are provided with semi-circular grooves.

[0029] In the above embodiment, the circular crucible clamp includes two clamping parts 1, and the tops of the two clamping parts 1 are connected by a crossbar 2. Each clamping part 1 includes two first connecting rods 11 and two second connecting rods 12. One end of each of the two first connecting rods 11 is rotatably connected to a first rotating shaft 111 at the bottom of the crossbar 2. The second connecting rods 12 are bent, and the ends of the two second connecting rods 12 away from the first rotating shaft 111 are connected to one end of each of the two second connecting rods 12 via a second rotating shaft 121. When the crossbar 2 is pulled upwards, the crossbar 2 pulls the connection ends of the first connecting rods 11 and the first rotating shaft 111 upwards, thereby bringing the ends of the two first connecting rods 11 away from the first rotating shaft 111 closer together, causing the connection ends of the two second connecting rods 12 and the second rotating shaft 121 to move closer together. The second connecting rods 12 are bent, and the bodies of the two second connecting rods 12 are rotatably connected via a third rotating shaft 123. Figure 1 As shown, Figure 1 This is a schematic diagram of the closed clamping state of the first clamping block 122 and the second clamping block 311. In the initial state, the first clamping block 122 and the second clamping block 311 are in a separated state. When in use, when the connecting ends of the two second connecting rods 12 and the second rotating shaft 121 are close together, the rod body of the second connecting rod 12 rotates around the third rotating shaft 123, so that the ends of the two second connecting rods 12 away from the second rotating shaft 121 are close together. A connecting column 31 is provided at the bottom of the beam rod 3, and a second clamping block 311 is provided at the bottom of the connecting column 31. Semicircular slots are provided on both sides of the second clamping block 311. The second connecting rod 12 drives the first clamping block 122 and the second clamping block 311 to move closer together, so that the semicircular slots of the first clamping block 122 and the semicircular slots of the second clamping block 311 are clamped and connected to achieve the clamping of the round crucible. By engaging the semi-circular slots on both sides of the second clamping block 311 with the first clamping blocks 122 on both sides of the second clamping block 311, multiple round crucibles in two rows can be clamped and fixed, which is beneficial to improving the efficiency of crucible clamping and transfer after heating.

[0030] In one embodiment of this application, see [reference] Figure 1 As shown, the first connecting rod 11 and the second connecting rod 12 are configured with double-layer clamping plates.

[0031] In the above embodiments, the first connecting rod 11 and the second connecting rod 12 are configured with double-layer clamping plates, which can increase the cross-section of the connecting rod under stress, that is, increase the strength of the connecting rod when under stress, prevent the connecting rod from deforming under stress, and help improve the stability of the clamp during use.

[0032] In one embodiment of this application, see [reference] Figure 1 As shown, a reinforcing plate 5 is provided between the double-layer clamping plates of the second connecting rod 12.

[0033] In the above embodiment, the reinforcing plate 5 is used to connect the double-layer clamping plates of the second link 12, so that the double-layer clamping plates of the second link 12 are integrated, that is, the overall connection of the double-layer clamping plates is increased, which is beneficial to further improve the strength of the second link 12 and to improve the stability of the fixture during use.

[0034] In one embodiment of this application, see [reference] Figure 2 As shown, a safety chain 21 is provided between the crossbar 2 and the beam 3.

[0035] In the above embodiment, the safety chain 21 between the crossbar 2 and the beam 3 is used to connect the crossbar 2 and the beam 3. Optionally, the safety chain 21 can be a metal chain. When the chain is set, there is a margin of movement between the crossbar 2 and the beam 3. The second clamping block 311 is integrally formed and has a larger self-weight than the first clamping block 122. If the second clamping block 311 pulls the beam 3 and falls off when the clamp moves, the chain is used to pull the fallen beam 3 to prevent the second clamping block 311 from causing the beam 3 to fall off, which helps to improve the safety of the clamp during use.

[0036] In one embodiment of this application, see reference Figure 5 As shown, the inner sides of the semi-circular slots of the first clamping block 122 and the second clamping block 311 are provided with groove patterns.

[0037] In the above embodiments, the groove pattern is used to increase the roughness of the inner surface of the semi-circular groove, thereby increasing the friction between the inner surface of the semi-circular groove and the outer wall of the round crucible when the clamping block holds the round crucible, making the clamping block hold the round crucible more stable.

[0038] In one embodiment of this application, the connection between the second connecting rod 12 and the first clamping block 122, and the connection between the connecting post 31 and the second clamping block 311, is a detachable connection.

[0039] In the above embodiments, the connection between the second connecting rod 12 and the first clamping block 122, and the connection between the connecting column 31 and the second clamping block 311, is a detachable connection. Optionally, the detachable connection can be a snap-fit ​​connection or a connection via a pin, which facilitates the disassembly and replacement of the clamping blocks on the connecting rod and the connecting column 31. By replacing the clamping blocks of different sizes, the fixture can be adapted to clamping round crucibles of different sizes, thereby improving the adaptability of the fixture.

[0040] In one embodiment of this application, see reference Figure 1 As shown, a hanging ring 6 is installed on the upper end face of the crossbar 2.

[0041] In the above embodiment, the hanging ring 6 is used to cooperate with the hook on the lifting device so that the crucible can be lifted and transferred after being clamped by the clamp.

[0042] In actual use of this application: when the crossbar 2 is pulled upward, the crossbar 2 pulls the connecting end of the first connecting rod 11 and the first rotating shaft 111 upward, thereby causing the ends of the two first connecting rods away from the first rotating shaft 111 to move closer together, which in turn causes the connecting ends of the two second connecting rods 12 and the second rotating shaft 121 to move closer together. The second connecting rods 12 are bent, and the rod bodies of the two second connecting rods 12 are rotatably connected through the third rotating shaft 123. Figure 1 As shown, when the two second connecting rods 12 approach the connecting ends of the second rotating shaft 121, the rod body of the second connecting rod 12 rotates around the third rotating shaft 123, causing the ends of the two second connecting rods 12 away from the second rotating shaft 121 to approach each other. A connecting column 31 is provided at the bottom end of the beam rod 3, and a second clamping block 311 is provided at the bottom end of the connecting column 31. Semi-circular slots are provided on both sides of the second clamping block 311. The second connecting rod 12 drives the first clamping block 122 to approach the second clamping block 311, so that the semi-circular slots of the first clamping block 122 and the semi-circular slots of the second clamping block 311 are clamped and connected to each other to achieve clamping of the round crucible. The semi-circular slots on both sides of the second clamping block 311 are clamped and connected to the first clamping blocks 122 on both sides of the second clamping block 311 to achieve clamping of the round crucible between the two clamping blocks. Then, the crucible is clamped and transported by hoisting the round crucible clamp.

[0043] 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.
