Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a lifting equipment for heat treatment. Background Technology

[0002] Heat treatment lifting tools are used to lift and fix workpieces during the metal heat treatment process. They can accurately lift workpieces into heat treatment equipment, such as heating furnaces and quenching tanks, and lift them out after treatment, improving work efficiency and reducing the labor intensity and risks of manual handling.

[0003] When using a heat treatment basket to heat treat metal, the metal workpiece needs to be placed in the basket before being placed into the heat treatment equipment for processing. However, when the basket is placed into the heat treatment equipment, it is easy for the basket to shake, which can cause the metal workpiece to tilt and shift within the basket. This can result in uneven distribution of the metal workpiece within the basket, and in severe cases, it can even cause the metal workpiece to fall out of the basket, making it difficult to perform normal heat treatment processing on the metal workpiece. Utility Model Content

[0004] This utility model addresses the problem that hanging baskets are prone to swaying, which can cause metal workpieces to tilt and shift within the basket, resulting in uneven distribution of the workpieces and, in severe cases, even causing them to fall out of the basket, thus hindering normal heat treatment processing. Therefore, this invention provides a heat treatment lifting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heat treatment lifting device, comprising a basket body, a connecting rod welded to the middle of the bottom of the inner wall of the basket body, a lifting ring welded to the top of the outer surface of the connecting rod, and an auxiliary device provided inside the basket body, the auxiliary device limiting and blocking the metal workpiece placed inside the basket body by setting a first semicircular plate and a second semicircular plate.

[0006] The effect achieved by the above components is as follows: by setting the first semicircular plate and the second semicircular plate, and adjusting the first semicircular plate and the second semicircular plate so that the first semicircular plate and the second semicircular plate abut against the metal workpiece inside the basket body, the first semicircular plate and the second semicircular plate can block the metal workpiece, so that when the basket shakes, it helps to prevent the metal workpiece from tilting or falling out of the basket body, and facilitates the normal heat treatment processing of the metal workpiece.

[0007] Preferably, the auxiliary device includes a circular block, which is slidably mounted on the outer surface of the connecting rod. A first semicircular plate is fixedly mounted on the outer surface of the circular block, and a second semicircular plate is provided on the top of the first semicircular plate. The second semicircular plate is rotatably mounted on the outer surface of the circular block.

[0008] The effect achieved by the above components is as follows: pushing the circular block causes the first and second semicircular plates to move away from the bottom of the inner wall of the basket body, and rotating the second semicircular plate so that the second and first semicircular plates overlap each other, thus creating a semicircular feed port between the first and second semicircular plates and the basket body, facilitating the input of metal materials. Then rotating the second semicircular plate causes the second and first semicircular plates to close together, and pushing the first and second semicircular plates downwards so that the top of the metal material abuts against the bottom of the first and second semicircular plates, thus limiting and blocking the metal workpiece.

[0009] Preferably, the bottom of the circular block and the bottom of the inner wall of the basket body are fixedly installed with the same spring, and the spring is sleeved on the outer surface of the circular rod.

[0010] The effect achieved by the above components is as follows: by setting the spring, when the spring is not subjected to other external forces, the spring can support the first and second semicircular plates connected to the circular block, thereby causing the first and second semicircular plates to move away from the bottom of the inner wall of the basket body, making it easier to put metal workpieces into the basket.

[0011] Preferably, a screw hole block is fixedly installed on the top of the circular block, one side of the screw hole block is in contact with the outer surface of the connecting rod, and a bolt is threaded into the inner wall of the screw hole block.

[0012] The effect achieved by the above components is as follows: by rotating the bolt, one end of the bolt passes through the inner wall of the bolt hole block until one end of the bolt abuts against the outer surface of the connecting rod, the bolt can fix the circular block and the connecting rod, thereby helping to prevent the first and second semicircular plates from shifting on the outer surface of the connecting rod.

[0013] Preferably, a rubber strip is installed on the inner wall of the connecting rod, and the bolt is located on one side of the rubber strip, wherein the rubber strip is made of fluororubber.

[0014] The effect achieved by the above components is as follows: by setting a rubber strip made of fluororubber, fluororubber can maintain good physical properties in high temperature environment, and thus can replace the outer surface of the connecting rod to abut against one end of the bolt, thereby increasing the friction between the bolt and the connecting rod, making the bolt less likely to loosen.

[0015] Preferably, the outer surface of the circular block is threaded with an operating ring, the outer surface of the operating ring is uniformly provided with protrusions, and the operating ring is located on the top of the second semicircular plate.

[0016] The effect achieved by the above components is as follows: by setting the operating ring, rotating the operating ring so that the bottom of the operating ring abuts against the top of the second semicircular plate, the operating ring can fix the second semicircular plate and the connecting rod, thereby fixing the second semicircular plate to prevent the second semicircular plate from rotating during the heat treatment process, which would cause the metal workpiece to detach from the basket body. At the same time, the protrusions on the outer surface of the operating ring can increase the friction of the outer surface of the operating ring, so as to have an anti-slip effect when rotating the operating ring.

[0017] Preferably, the top of the operating ring is provided with a circular ring, which is fixedly installed on the top of the outer surface of the connecting rod.

[0018] The effect achieved by the above components is that by setting up a ring, the ring can block the operating ring, which helps to prevent the operating ring from detaching from the connecting rod due to misoperation.

[0019] Preferably, a slider is installed on the inner wall of the circular block, and the outer surface of the slider is slidably installed on the inner wall of the connecting rod.

[0020] The effect achieved by the above components is that by setting the slider, the slider can limit the circular block, which helps to prevent the circular block from rotating on the outer surface of the connecting rod, thus preventing the spring from being twisted and deformed.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a first semicircular plate and a second semicircular plate, and adjusting the first and second semicircular plates so that they abut against the metal workpiece inside the basket body, the first and second semicircular plates can block the metal workpiece. This helps prevent the metal workpiece from tilting or falling out of the basket body when the basket shakes, thus facilitating normal heat treatment processing of the metal workpiece.

[0028] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a heat treatment lifting device, including a basket body. A connecting rod 2 is welded to the middle of the bottom of the inner wall of the basket body, and a lifting ring 3 is welded to the top of the outer surface of the connecting rod 2. An auxiliary device 4 is provided inside the basket body. The auxiliary device 4 limits and blocks the metal workpiece placed inside the basket body by setting a first semicircular plate 42 and a second semicircular plate 43. By setting the first semicircular plate 42 and the second semicircular plate 43, the first semicircular plate 42 and the second semicircular plate 43 are adjusted so that the first semicircular plate 42 and the second semicircular plate 43 abut against the metal workpiece inside the basket body. The first semicircular plate 42 and the second semicircular plate 43 can block the metal workpiece, so that when the basket shakes, it helps to prevent the metal workpiece from tilting or falling out of the basket body, which facilitates the normal heat treatment processing of the metal workpiece.

[0029] Reference Figure 2 and Figure 3 As shown, the auxiliary device 4 includes a circular block 41, which is slidably mounted on the outer surface of the connecting rod 2. A first semicircular plate 42 is fixedly mounted on the outer surface of the circular block 41. A second semicircular plate 43 is provided on the top of the first semicircular plate 42. The second semicircular plate 43 is rotatably mounted on the outer surface of the circular block 41. Pushing the circular block 41 causes the first semicircular plate 42 and the second semicircular plate 43 to move away from the bottom of the inner wall of the basket body. Rotating the second semicircular plate 43 causes the second semicircular plate 43 and the first semicircular plate 42 to overlap each other, thus creating a semicircular feed port between the first semicircular plate 42 and the second semicircular plate 43 and the basket body, facilitating the input of metal materials. Rotating the second semicircular plate 43 further causes the second semicircular plate 43 and the first semicircular plate 42 to overlap each other. 2. When the two semicircular plates 42 and 43 are closed together and pushed downwards, the top of the metal material and the bottom of the first semicircular plate 42 and the second semicircular plate 43 come into contact. The first semicircular plate 42 and the second semicircular plate 43 can limit and block the metal workpiece. The bottom of the circular block 41 and the bottom of the inner wall of the basket body are fixedly installed with the same spring 44. The spring 44 is sleeved on the outer surface of the circular rod. By setting the spring 44, when the spring 44 is not subjected to other external forces, the spring 44 can support the first semicircular plate 42 and the second semicircular plate 43 connected to the circular block 41. This will cause the first semicircular plate 42 and the second semicircular plate 43 to move away from the bottom of the inner wall of the basket body, making it easier to put the metal workpiece into the basket.

[0030] Reference Figure 2 and Figure 3 As shown, a screw hole block 45 is fixedly installed on the top of the circular block 41. One side of the screw hole block 45 is in contact with the outer surface of the connecting rod 2. A bolt 46 is threaded into the inner wall of the screw hole block 45. By rotating the bolt 46, one end of the bolt 46 passes through the inner wall of the screw hole block 45 until one end of the bolt 46 abuts against the outer surface of the connecting rod 2. The bolt 46 can fix the circular block 41 and the connecting rod 2, thereby helping to prevent the first semicircular plate 42 and the second semicircular plate 43 from shifting on the outer surface of the connecting rod 2. A rubber strip 47 is installed on the inner wall of the connecting rod 2. The bolt 46 is located on one side of the rubber strip 47. The rubber strip 47 is made of fluororubber. By setting the rubber strip 47 made of fluororubber, fluororubber can maintain good physical properties in a high-temperature environment. It can replace the outer surface of the connecting rod 2 and abut against one end of the bolt 46, thereby increasing the friction between the bolt 46 and the connecting rod 2, making the bolt 46 less likely to loosen.

[0031] Reference Figure 2 and Figure 3 As shown, an operating ring 48 is threadedly connected to the outer surface of the circular block 41. The outer surface of the operating ring 48 is uniformly provided with protrusions. The operating ring 48 is located on the top of the second semicircular plate 43. By rotating the operating ring 48, the bottom of the operating ring 48 abuts against the top of the second semicircular plate 43, thus fixing the second semicircular plate 43 and the connecting rod 2. This helps to prevent the second semicircular plate 43 from rotating during heat treatment, which could cause the metal workpiece to detach from the basket body. At the same time, the protrusions on the outer surface of the operating ring 48 increase the friction of the outer surface of the operating ring 48, providing an anti-slip effect when rotating the operating ring 48. A circular ring 49 is provided on the top of the operating ring 48. The circular ring 49 is fixedly installed on the top of the outer surface of the connecting rod 2. By providing the circular ring 49, the circular ring 49 can block the operating ring 48, which helps to prevent the operating ring 48 from detaching from the connecting rod 2 due to misoperation.

[0032] Reference Figures 2-4 As shown, a slider 410 is installed on the inner wall of the circular block 41. The outer surface of the slider 410 is slidably installed on the inner wall of the connecting rod 2. By setting the slider 410, the slider 410 can limit the circular block 41, which helps to prevent the circular block 41 from rotating on the outer surface of the connecting rod 2, thus preventing the spring 44 from being twisted and deformed.

[0033] Working principle: When the spring 44 is not subjected to any external force, it supports the first semicircular plate 42 and the second semicircular plate 43 connected to the circular block 41, thereby moving the first semicircular plate 42 and the second semicircular plate 43 away from the bottom of the inner wall of the basket body. Rotating the second semicircular plate 43 causes it to overlap with the first semicircular plate 42, creating a semicircular inlet between the first semicircular plate 42 and the basket body, facilitating the input of metal materials. Further rotation of the second semicircular plate 43 causes it to close with the first semicircular plate 42, pushing the first semicircular plate 42 and the second semicircular plate 43 downwards, causing the top of the metal material to abut against the bottom of the first semicircular plate 42 and the second semicircular plate 43. This allows the first semicircular plate 42 and the second semicircular plate 43 to limit and block the metal workpiece. The bolt 46 is rotated so that one end of the bolt 46 passes through the inner wall of the bolt hole block 45 until one end of the bolt 46 abuts against the rubber strip 47 on the outer surface of the connecting rod 2. The bolt 46 can then fix the circular block 41 and the connecting rod 2, thereby preventing the first semicircular plate 42 and the second semicircular plate 43 from shifting on the outer surface of the connecting rod 2. The operating ring 48 is rotated so that the bottom of the operating ring 48 abuts against the top of the second semicircular plate 43. The operating ring 48 can then fix the second semicircular plate 43 and the connecting rod 2, thereby fixing the second semicircular plate 43. This helps to prevent the second semicircular plate 43 from rotating during the heat treatment process, which could cause the metal workpiece to detach from the basket body. At the same time, the protrusions on the outer surface of the operating ring 48 can increase the friction of the outer surface of the operating ring 48, providing an anti-slip effect when rotating the operating ring 48.
