Abstract
Description
Technical Field
[0001] This utility model relates to the field of growth furnace frame technology, and in particular to column assemblies for crystal growth furnace frames. Background Technology
[0002] A single-crystal silicon growth furnace is a type of equipment that melts polycrystalline materials such as polycrystalline silicon using a graphite heater in a vacuum and inert gas (mainly argon) environment. The Czochralski single-crystal furnace is a key technology and equipment for producing single-crystal silicon. During the use of a single-crystal silicon growth furnace, a connecting bracket is needed to connect and fix the furnace to ensure that the single-crystal silicon grows in a relatively stable environment.
[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When installing and using the single crystal silicon growth furnace support, it is necessary to climb to operate the single crystal silicon growth furnace. However, often only a climbing ladder is installed, but no safety measures are provided. This may cause workers to fall while climbing on the frame, resulting in low safety performance of the device. Utility Model Content
[0004] To solve the above problems, this utility model provides a column assembly for a crystal growth furnace frame.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a column assembly for a crystal growth furnace frame, comprising a column body, the column body comprising a column sleeve and a column rod slidably disposed within the column sleeve, a first fixing plate being fitted on the outer wall of the column sleeve, the first fixing plate being fixed to the column sleeve, a second fixing plate being fitted on the outer wall of the column rod, the second fixing plate being fixed to the column rod, and an adjustment component for adjusting the height of the column rod being provided on both the first fixing plate and the second fixing plate.
[0006] By adopting the above technical solution, when workers need to climb to the top of the growth furnace column, they need to activate the adjustment component, which moves the column rod and the second fixed rod downwards. At this point, workers can operate directly without climbing, thus reducing the risk of falls and improving the safety of the equipment.
[0007] Furthermore, the adjustment assembly includes multiple first rotating seats arranged in an array on the upper surface of the first fixed plate, multiple second rotating seats arranged in an array on the bottom surface of the second fixed plate, and multiple rotating rods respectively rotatably mounted on the multiple first rotating seats. The other ends of the multiple rotating rods are respectively rotatably connected to the multiple second rotating seats. The first rotating seats are slidably connected to the first fixed plate, and the second rotating seats are slidably connected to the second fixed plate.
[0008] Furthermore, the upper surface of the first fixing plate and the bottom surface of the second fixing plate are both provided with an array of sliding grooves, and a slider is slidably disposed in each of the multiple sliding grooves. The multiple sliders are respectively fixed to the adjacent first rotating seat or second rotating seat.
[0009] By adopting the above technical solution, when the worker needs to slide the column downwards, the worker slides the column downwards, causing the second fixing plate to move downwards under the action of the column. This causes the first rotating seat and the second rotating seat to slide, which in turn causes the slider to slide under the action of the first and second rotating seats, thus causing the rotating rod to rotate. During this process, the rotating rod rotates relative to the first and second rotating seats, thereby adjusting the height of the column. At this time, the worker can operate directly without climbing, thus reducing the risk of the worker falling and improving the safety of the device.
[0010] Furthermore, a rotating shaft is provided on two adjacent rotating rods, and the rotating shaft passes through the rotating rod and is rotatably connected to the rotating rod.
[0011] By adopting the above technical solution, when the rotating rod rotates, the rotating shaft and the rotating rod rotate relative to each other. During this process, the rotating shaft limits the rotation of the rotating rod, thereby reducing the probability of the rotating rod shaking when it rotates, and thus improving the stability of the device.
[0012] Furthermore, a first rotating seat is slidably disposed on the upper surface of the first fixed plate, and a second rotating seat is fixedly disposed on the bottom surface of the second fixed plate. A rotating rod is rotatably disposed at one end of the first rotating seat and the second rotating seat that are close to each other.
[0013] Furthermore, a drive groove is provided on the upper surface of the second fixed plate, and a drive block is slidably disposed in the drive groove. The drive block is fixed to the first rotating seat. A threaded rod is rotatably disposed on the side wall of the second fixed plate, and the threaded rod is threadedly connected to the drive block.
[0014] By adopting the above technical solution, when the worker needs to slide the column rod downwards, the worker needs to rotate the threaded rod, which in turn causes the drive block to slide under the action of the threaded rod. This causes the first rotating seat to move synchronously with the drive block under the action of the drive block, resulting in relative rotation between the rotating rod and the first rotating seat. This causes the second fixed plate to move downwards, thereby causing the column rod to slide downwards. This reduces the difficulty for the worker in sliding the column rod, thus reducing the workload. In addition, it also reduces the probability of the column rod sliding downwards under the action of gravity, thereby improving the stability of the device.
[0015] Furthermore, a limiting hole is formed on the inner wall of the drive groove, and a limiting rod is rotatably arranged in the limiting hole, with the limiting rod and the threaded rod being fixed to each other.
[0016] By adopting the above technical solution, when the threaded rod rotates, the limiting rod rotates under the action of the threaded rod. During this process, the limiting rod is... Figure 4 As shown, the limiting rod limits the threaded rod, thereby reducing the probability of the threaded rod moving and improving the stability of the device.
[0017] Furthermore, a rocker arm is fixedly installed on the side wall of the threaded rod.
[0018] By adopting the above technical solution, the rocker arm reduces the difficulty for workers to rotate the threaded rod, thereby reducing the difficulty of their work.
[0019] Furthermore, a limiting member is fitted on the outer wall of the rotating shaft, and the side wall of the limiting member abuts against the side wall of the rotating rod.
[0020] By adopting the above technical solution, the limiting component reduces the probability of the rotating shaft and the rotating rod separating from each other, thereby improving the stability of the device.
[0021] Furthermore, the width of the slider gradually increases from the end closer to the rotating rod to the end farther away from the rotating rod.
[0022] By adopting the above technical solution, the width of the slider gradually increases from the end closer to the rotating rod to the end farther away from the rotating rod, which reduces the probability of the first rotating seat and the second rotating seat separating from the first fixed plate and the second fixed plate, thereby improving the stability of the device.
[0023] In summary, this utility model has the following beneficial effects:
[0024] 1. In this application, when a worker needs to climb to the top of the growth furnace column, the worker must activate the adjustment component, which moves the column rod and the second fixed rod downwards under the action of the adjustment component. At this time, the worker can operate directly without climbing, thereby reducing the risk of the worker falling and improving the safety of the device;
[0025] 2. In this application, when the worker needs to slide the column downwards, the worker slides the column downwards, causing the second fixing plate to move downwards under the action of the column. This causes the first rotating seat and the second rotating seat to slide, which in turn causes the slider to slide under the action of the first and second rotating seats, causing the rotating rod to rotate. During this process, the rotating rod rotates relative to the first and second rotating seats, thereby adjusting the height of the column. At this time, the worker can operate directly without climbing, thus reducing the risk of the worker falling and improving the safety of the device.
[0026] 3. In this application, when the rotating rod rotates, the rotating shaft and the rotating rod rotate relative to each other. During this process, the rotating shaft limits the rotating rod, thereby reducing the probability of the rotating rod shaking when it rotates, thus improving the stability of the device.

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0033] like Figure 1-4As shown in the embodiment of this application, a column assembly for a crystal growth furnace frame is disclosed, including a column body 1, a first fixing plate 13, a second fixing plate 14, an adjustment assembly 2, a slider 31, a rotating shaft 4, a first rotating seat 5, a second rotating seat 51, a rotating rod 52, a driving block 61, a threaded rod 62, and a limiting rod 71. The column body 1 includes a column sleeve 11 and a column rod 12. The column sleeve 11 is a hollow cuboid structure. The column rod 12 is a rectangular rod structure and is slidably disposed within the column sleeve 11. The first fixing plate 13 is a rectangular plate structure and is sleeved on the outer wall of the column sleeve 11, and the first fixing plate 13 and the column sleeve 11 are fixed to each other. The second fixing plate 14 is a rectangular plate structure and is sleeved on the outer wall of the column rod 12, and the second fixing plate 14 and the column rod 12 are fixed to each other.
[0034] When workers need to climb to the top of the growth furnace column, they must activate the adjusting component 2. This causes the column rod 12 and the second fixed rod to move downwards under the action of the adjusting component 2. At this point, workers can operate directly without climbing, thus reducing the risk of falls and improving the safety of the equipment.
[0035] Adjustment assembly 2 is disposed on the first fixed plate 13 and the second fixed plate 14 for adjusting the height of the column rod 12. Adjustment assembly 2 includes a first rotating seat 21, a second rotating seat 22, and rotating rods 23. Multiple first rotating seats 21 are arranged in a parallel array on the upper surface of the first fixed plate 13, and are slidably connected to the first fixed plate 13. Multiple second rotating seats 22 are arranged in a parallel array on the bottom surface of the second fixed plate 14, and are slidably connected to the second fixed plate 14. Multiple rotating rods 23 are respectively rotatably disposed on multiple first rotating seats 21, and the other ends of the multiple rotating rods 23 are respectively rotatably connected to multiple second rotating seats 22.
[0036] The upper surface of the first fixed plate 13 and the bottom surface of the second fixed plate 14 are both provided with grooves 3. Multiple sliders 31 are provided and are slidably disposed in the multiple grooves 3 respectively. The multiple sliders 31 are respectively fixed to the adjacent first rotating seat 21 or second rotating seat 22.
[0037] When the operator needs to slide the column rod 12 downwards, the second fixing plate 14 moves downwards under the action of the column rod 12. This causes the first rotating seat 21 and the second rotating seat 22 to slide, which in turn causes the slider 31 to slide under the action of the first rotating seat 21 and the second rotating seat 22. This causes the rotating rod 23 to rotate relative to the first rotating seat 21 and the second rotating seat 22, thereby adjusting the height of the column rod 12. At this time, the operator can operate directly without climbing, thus reducing the risk of falling and improving the safety of the device.
[0038] The rotating shaft 4 is a round rod structure with its axis horizontal. The rotating shaft 4 is rotatably mounted on two adjacent rotating rods 23. The rotating shaft 4 passes through the rotating rods 23 and is rotatably connected to the rotating rods 23.
[0039] When the rotating rod 23 rotates, the rotating shaft 4 rotates relative to the rotating rod 23. During this process, the rotating shaft 4 limits the rotation of the rotating rod 23, thereby reducing the probability of the rotating rod 23 shaking when it rotates, thus improving the stability of the device.
[0040] The first rotating seat 5 is slidably disposed on the upper surface of the first fixed plate 13, the second rotating seat 51 is fixedly disposed on the bottom surface of the second fixed plate 14, and the two ends of the rotating rod 52 are respectively rotatably disposed at the ends of the first rotating seat 5 and the second rotating seat 51 that are close to each other.
[0041] The upper surface of the second fixed plate 14 is provided with a drive groove 6. The drive block 61 is a rectangular block structure and is slidably disposed in the drive groove 6. The drive block 61 is fixed to the first rotating seat 5. The threaded rod 62 is rotatably disposed on the side wall of the second fixed plate 14 with its axis horizontal. The threaded rod 62 is threadedly connected to the drive block 61.
[0042] When the worker needs to slide the column rod 12 downwards, the worker needs to rotate the threaded rod 62, which in turn causes the drive block 61 to slide under the action of the threaded rod 62. This causes the first rotating seat 5 to move synchronously with the drive block 61 under the action of the drive block 61, thereby causing the rotating rod 52 to rotate relative to the first rotating seat 5. This causes the second fixed plate 14 to move downwards, which in turn causes the column rod 12 to slide downwards. This reduces the difficulty for the worker to slide the column rod 12, thus reducing the workload. In addition, it also reduces the probability of the column rod 12 sliding downwards under the action of gravity, thereby improving the stability of the device.
[0043] A limiting hole 7 is provided on the inner wall of the drive groove 6. The limiting rod 71 is rotatably set in the limiting hole 7, and its axis coincides with the axis of the threaded rod 62. The limiting rod 71 and the threaded rod 62 are fixed to each other.
[0044] When the threaded rod 62 rotates, the limiting rod 71 rotates under the action of the threaded rod 62. During this process, the limiting rod 71 is... Figure 4 As shown, the limiting rod 71 limits the threaded rod 62, thereby reducing the probability of the threaded rod 62 moving and thus improving the stability of the device.
[0045] To reduce the difficulty of the work for the workers, a rocker arm 8 is fixedly installed on the side wall of the threaded rod 62. The rocker arm 8 reduces the difficulty for the workers to rotate the threaded rod 62, thereby reducing the difficulty of the work for the workers.
[0046] To improve the stability of the device, a limiting member 9 is fitted onto the outer wall of the rotating shaft 4, and the side wall of the limiting member 9 abuts against the side wall of the rotating rod 23. The limiting member 9 reduces the probability of the rotating shaft 4 and the rotating rod 23 separating from each other, thereby improving the stability of the device.
[0047] To improve the stability of the device, the width of the slider 31 gradually increases from the end closer to the rotating rod 23 to the end farther away from the rotating rod 23. This gradual increase in the width of the slider 31 reduces the probability of the first rotating seat 21 and the second rotating seat 22 separating from the first fixed plate 13 and the second fixed plate 14, thereby improving the stability of the device.
[0048] In this embodiment, the operating principle of the column assembly for the crystal growth furnace frame is as follows: When a worker needs to climb to the top of the column, they must rotate the threaded rod 62. This causes the drive block 61 to slide under the action of the threaded rod 62, resulting in the first rotating seat 5 moving synchronously with the drive block 61. This causes the rotating rod 52 to rotate relative to the first rotating seat 5, which in turn causes the second fixed plate 14 to move downwards. This causes the column rod 12 to slide downwards, resulting in the first rotating seat 21 and the second rotating seat 22 sliding together. This causes the slider 31 to slide under the action of the first rotating seat 21 and the second rotating seat 22, causing the rotating rod 23 to rotate. During this process, the rotating rod 23 rotates relative to the first rotating seat 21 and the second rotating seat 22, thereby adjusting the height of the column rod 12. At this point, the worker can operate directly without climbing, reducing the risk of falls and improving the safety of the device.
[0049] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
