Description

Technical Field

[0001] This application relates to the technical field of electrode configurations, and more particularly to an insulating ring gripper for a polysilicon reduction electrode. Background Art

[0002] With the development of the polysilicon production process, when producing polysilicon by the improved Siemens method in a polysilicon reduction furnace, an electrode insulating ring needs to be installed on the reduction furnace electrode to isolate the electrode from the metal chassis and achieve an insulating effect.

[0003] However, due to reasons such as the thermal expansion and contraction of the electrode during intermittent production and the support for polysilicon rod production in the prior art, the electrode insulating ring cannot be removed for cleaning after being clamped to the electrode. In order to remove the electrode insulating ring, the operator can only use a rubber hammer or a tungsten carbide hammer to strike the electrode insulating ring to loosen the connection between the electrode and the electrode insulating ring. However, the rubber hammer has the disadvantages of large elastic force and a large number of strikes; the tungsten carbide hammer has a single stress point and is likely to break the electrode insulating ring, and even affect the perpendicularity of the electrode. Utility Model Content

[0004] The purpose of this application is to provide an insulating ring gripper for a polysilicon reduction electrode to eliminate the need to remove the electrode insulating ring by striking, thereby avoiding damage to the electrode and the electrode insulating ring.

[0005] To achieve the above object, the technical solution adopted in this application is: an insulating ring gripper for a polysilicon reduction electrode, comprising: a gripper body for tightly fitting with the electrode insulating ring; a connecting handle connected to the gripper body, and the extending direction of the connecting handle is perpendicular to the plane where the gripper body is located.

[0006] Preferably, the gripper body includes: a first gripper portion and a second gripper portion, and the first end of the first gripper portion is movably connected to the first end of the second gripper portion; wherein, the first gripper portion and the second gripper portion are used to fit the electrode insulating ring, and by the relative approach of the first gripper portion and the second gripper portion, the gripper body tightly fits the electrode insulating ring.

[0007] Preferably, the first gripper portion is provided with a first arc-shaped abutting surface, and the second gripper portion is provided with a second arc-shaped abutting surface, and the electrode insulating ring is tightly fitted through the first arc-shaped abutting surface and the second arc-shaped abutting surface.

[0008] More preferably, the first gripper portion and the second gripper portion are rotatably connected by a rotating shaft.

[0009] More preferably, the second ends of the first gripper portion and the second gripper portion are spaced apart from each other to define a first notch.

[0010] Further preferably, a plurality of connecting handles are provided, and the plurality of connecting handles are arranged on the periphery of the outer wall of the clamping body.

[0011] Further preferably, the connecting handle comprises: a first handle, wherein the first handle is connected to the periphery of the outer wall of the first clamping portion.

[0012] Furthermore, the connecting handle also includes: a second handle and a third handle, the second handle is connected to the second end of the first clamping portion, the second handle is spaced apart from the first handle, and the third handle is connected to the second end of the second clamping portion.

[0013] Furthermore, the clamping device further comprises: a first extending member, and the clamping body and the connecting handle are connected via the first extending member, so that a clearance space is formed between the connecting handle and the clamping body.

[0014] Preferably, the gripper further comprises: a second extension member, the second extension member is connected to the connecting handle, and the first extension member and the second extension member are arranged at opposite ends of the connecting handle.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] The connecting handle and the clamp body are arranged perpendicular to each other, so that the operator holding the connecting handle can better exert force vertically upward along the direction of gravity, which is convenient for removing the electrode insulating ring. At the same time, during the removal process of the electrode insulating ring, the connecting handle is arranged vertically relative to the clamp body. At this time, the electrode insulating ring is only subjected to pressure from the clamp body and a pulling force vertically upward along the connecting handle. The electrode insulating ring is subjected to fewer force directions, thereby reducing the risk of damage to the electrode insulating ring during the removal process.

[0021] Next, in combination with the detailed implementation manners, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0022] In the description of the present application, it should be noted that for orientation terms, such as terms "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the indicated orientation and position relationships are based on the orientation or position relationships shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be construed as limiting the specific protection scope of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence.

[0024] The terms "comprising" and "having" in the description and claims of the present application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0025] In a preferred implementation manner, specifically refer to Figures 1 to 2 , the present application provides a gripper 1 for a polysilicon reduction electrode insulating ring. The gripper 1 is used for gripping and disassembling the polysilicon reduction electrode insulating ring, hereinafter referred to as the electrode insulating ring for short. The gripper 1 includes: a gripping body 10, and the gripping body 10 is used for tightly fitting with the electrode insulating ring; a connecting handle 20, and the connecting handle 20 is connected to the gripping body 10, and the extending direction of the connecting handle 20 is perpendicular to the plane where the gripping body 10 is located.

[0026] Among them, the gripper body 10 is specifically a pressing ring structure. The outer wall of the electrode insulating ring is tightly attached to the inner wall of the gripper body 10. Due to the large friction generated by pressing the outer wall of the electrode insulating ring through the inner wall of the gripper body 10, the gripper body 10 is fixed relative to the electrode insulating ring. At this time, the operator can hold the connecting handle 20 and remove the electrode insulating ring from the electrode by means of circumferential rotation, thus eliminating the need to remove the electrode insulating ring by knocking and avoiding damage to the electrode and the electrode insulating ring.

[0027] The connecting handle 20 is perpendicularly arranged with respect to the gripper body 10, enabling the operator to exert force vertically upward along the direction of gravity more easily when holding the connecting handle 20, which is convenient for removing the electrode insulating ring. At the same time, during the removal process of the electrode insulating ring, due to the perpendicular arrangement of the connecting handle 20 relative to the gripper body 10, the electrode insulating ring is only subjected to a pressure from the gripper body 10 and a pulling force vertically upward along the connecting handle 20. The direction of force on the electrode insulating ring is less, reducing the risk of damage to the electrode insulating ring during the removal process.

[0028] As a preference, the gripper body 10 includes a first gripper part 11 and a second gripper part 12. The first end of the first gripper part 11 is movably connected to the first end of the second gripper part 12. Among them, the first gripper part 11 and the second gripper part 12 are used to fit the electrode insulating ring. By moving the first gripper part 11 and the second gripper part 12 closer to each other, the gripper body 10 is tightly attached to the electrode insulating ring.

[0029] Among them, the first gripper part 11 and the second gripper part 12 are connected in a relatively movable manner, making the gripper body 10 a structure with an adjustable gripper width, increasing the application range of the gripper 1 in this application document, and enabling the gripper 1 to adapt to electrode insulating rings with different diameters under different working conditions. Preferably, the first gripper part 11 and the second gripper part 12 are rotationally connected by a rotating shaft 30. The rotating shaft 30 is specifically a rotating nut. The mating surface between the second gripper part 12 and the first gripper part 11 is arc-shaped, making the rotation of the second gripper part 12 relative to the first gripper part 11 smoother. The arc-shaped abutting surface ensures that the second gripper part 12 will not get stuck relative to the first gripper part 11 during actual rotation, and the relatively rotatable first gripper part 11 and second gripper part 12 also make the pressing operation of the gripper body 10 on the electrode insulating ring to be removed more convenient.

[0030] As another preference, the first gripper part 11 is provided with a first arc-shaped abutting surface 111, and the second gripper part 12 is provided with a second arc-shaped abutting surface 121. The first arc-shaped abutting surface 111 and the second arc-shaped abutting surface 121 are tightly attached to the electrode insulating ring.

[0031] The first arc-shaped abutting surface 111 is also the inner wall part of the first clamping part 11, and the second arc-shaped abutting surface 121 is also the inner wall part of the second clamping part 12. The arc length of the first arc-shaped abutting surface 111 is greater than that of the second arc-shaped abutting surface 121. Therefore, during actual operation, when the clamping body 10 is pressed against and attached to the electrode insulating ring, first, the first arc-shaped abutting surface 111 adheres to the outer wall of the electrode insulating ring. The first clamping part 11 where the first arc-shaped abutting surface 111 is located is the main body. The second clamping part 12 gradually approaches the first clamping part 11 so that the second arc-shaped abutting surface 121 gradually approaches, adheres to, and presses the electrode insulating ring, thereby completing the pressing of the clamping body 10 on the electrode insulating ring.

[0032] Preferably, the inner diameter d1 of the circular clamping space formed by the first arc-shaped abutting surface 111 and the second arc-shaped abutting surface 121 is preferably 104 millimeters.

[0033] Further preferably, the second ends of the first clamping part 11 and the second clamping part 12 are spaced apart from each other to define a first notch 13. The opening length d2 of the first notch 13 is preferably 20 millimeters. The setting of the first notch 13 makes the first clamping part 11 and the second clamping part 12 not completely close when clamping the electrode insulating ring, so that the gripper 1 of this application document has a certain clamping margin.

[0034] Further preferably, a plurality of connecting handles 20 are provided, and the plurality of connecting handles 20 are arranged on the outer wall periphery of the clamping body 10.

[0035] Preferably, the connecting handle 20 in this application document includes: a first handle 21, and the first handle 21 is connected to the outer wall periphery of the first clamping part 11.

[0036] Furthermore, the connecting handle 20 further includes: a second handle 22 and a third handle 23. The second handle 22 is connected to the second end of the first clamping part 11, the second handle 22 is spaced from the first handle 21, and the third handle 23 is connected to the second end of the second clamping part 12.

[0037] Since the first clamping part 11 is the main part and the second clamping part 12 is the secondary part, the first handle 21 is fixedly connected to the first clamping part 11, facilitating the operator to hold the first handle 21 to complete the initial abutting and limiting of the first clamping part 11 on the electrode insulating ring.

[0038] The second handle 22 and the third handle 23 are arranged at one end close to the first notch 13. During actual operation, the operator holds the first handle 21 with his left hand and squeezes and holds the second handle 22 and the third handle 23 with his right hand. The second handle 22 and the third handle 23 arranged close to the first notch 13 are convenient for the operator to hold and exert force with one hand to ensure the clamping effect of the clamp body 10 on the electrode insulating ring and prevent the clamp body from slipping out of the electrode insulating ring.

[0039] Furthermore, the clamping device 1 further comprises: a first extending member 40 , through which the clamping body 10 and the connecting handle 20 are connected, so that a clearance space 41 is formed between the connecting handle 20 and the clamping body 10 .

[0040] The first extension piece 40, the clamping body 10 and the connecting handle 20 are integrally formed. It should be noted that there are multiple first extension pieces 40. The first handle 21 is integrally formed with the first clamping part 11 through the first extension piece 40. Similarly, the second handle 22 is integrally formed with the second clamping part 12 through the first extension piece 40, and the third handle 23 is the same. The existence of the clearance space 41 increases the operator's operable range for the clamping device 1 and expands the operable space. When the operator holds the first handle 21 and the second handle 22, part of the operator's hand is located in the clearance space 41, so the visual blind spot caused by the hand blocking can be effectively reduced.

[0041] As a preferred embodiment, the clamping device 1 also includes: a second extension member 50, the second extension member 50 is connected to the connecting handle 20, the first extension member 40 and the second extension member 50 are arranged at opposite ends of the connecting handle 20, and similarly, a plurality of second extension members 50 are arranged, the second extension member 50 is integrally formed with the first handle 21, and the second extension member 50 is also integrally formed with the second handle 22, and the same applies to the third handle 23.

[0042] Among them, the protruding direction of the second extension piece 50 is set away from the side of the clamping body 10. Taking the first handle 21 as an example, a Z-shaped structure is formed between the second extension piece 50, the first handle 21 and the first extension piece 40. When the operator holds the first handle 21 with his hand, the second extension piece 50 rests on the base of the operator's hand, thereby further facilitating the operator to remove the electrode insulating ring from the electrode upward in the vertical direction, thereby reducing the difficulty of removing the electrode insulating ring.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present application.
