Description

Technical Field

[0001] The embodiments of this utility model relate to the field of furnace shell auxiliary technology, specifically, to a furnace shell removal device. Background Technology

[0002] Shell removal tools are commonly used in industrial production, especially in fields such as casting and metallurgy, to remove the shell or casting from the mold inside the furnace.

[0003] In existing technologies, shells are usually picked out of the furnace by hand using a shell-picking tool. At this time, the temperature inside the furnace is very high, making it impossible to use the tool normally. Therefore, the shell-picking tool needs to be cooled down to extend its service life. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a furnace shell removal device, which solves the problem in related technologies that cannot cool the shell removal tool.

[0005] According to one aspect, at least one embodiment of the present invention provides a furnace shell removal device, including a connecting handle, a hand grip fixedly connected to the top end of the connecting handle, a fixing clamp fixedly connected to the bottom end of the connecting handle, and a cooling mechanism provided inside the connecting handle.

[0006] The cooling mechanism includes a mounting plate and a micro motor. The side of the mounting plate is fixedly connected to the inner wall of the connecting handle. The side of the mounting plate is fixedly connected to the side of the micro motor. A rotating shaft is fixedly connected to the output end of the micro motor. A half gear is fixedly passed through the circumference of the rotating shaft. A sliding groove is opened inside the connecting handle. A rack is slidably connected inside the sliding groove. A moving column is fixedly connected to the side of the rack. A cooling box is fixedly connected inside the connecting handle. The circumference of the moving column passes through and is slidably connected to the side of the cooling box. An extrusion plate is slidably connected inside the cooling box. The side of the extrusion plate is fixedly connected to one end of the moving column. A conveying main pipe is fixedly passed through the side of the cooling box. A circulation pipe is fixedly connected to the circumference of the conveying main pipe.

[0007] For example, in at least one embodiment of the present invention, a furnace shell removal device is provided, which further includes: a tension spring fixedly connected to the inner wall of the connecting handle, and the end of the tension spring away from the inner wall of the connecting handle is fixedly connected to the side of the rack, the purpose of which is to ensure that the rack can automatically reset when it separates from the half gear, thereby reducing manual intervention.

[0008] One end of the circulation pipe is fixedly connected to a return pipe, and the end of the return pipe away from the circulation pipe is fixedly inserted through the side of the cooling tank. A one-way valve is provided on the circumferential surface of the return pipe to ensure that the used cooling water can be circulated through the return pipe and kept the coolant stable.

[0009] The fixing clamp is made of silicon carbide fiber reinforced ceramic matrix composite material, the fixing clamp has a temperature resistance of 1,600 degrees Celsius, the circulation tube is spiral in shape, and the channel diameter of the circulation tube is 1.5 millimeters.

[0010] The circumferential surface of the half gear meshes with the side surface of the rack. The number of circulation pipes is set to two, and they are symmetrical to each other along the vertical central axis of the cooling box. The purpose is to ensure that the rotation of the half gear can drive the rack to move, and the two ends of the fixed clamp are cooled simultaneously through the two circulation pipes.

[0011] According to another aspect, at least one embodiment of the present invention also provides a furnace shell removal device, including a clamping mechanism. The clamping mechanism includes an insert groove, which is formed inside a hand grip. A movable block is slidably connected inside the insert groove. A connecting rod is fixedly connected to the bottom of the movable block. A trigger block is fixedly connected to the end of the connecting rod away from the bottom of the movable block. A hydraulic cylinder is fixedly connected inside the fixing clamp. A force rod is slidably connected to one end of the hydraulic cylinder via a piston. A hydraulic rod is driven by the hydraulic cylinder. An adjusting plate is fixedly connected to the end of the hydraulic rod away from the side of the hydraulic cylinder. The purpose is to be able to clamp and remove shells of different sizes.

[0012] For example, in at least one embodiment of the present invention, a furnace shell removal device is provided, which further includes: a compression spring fixedly connected to the inner wall of the hand grip, and the end of the compression spring away from the inner wall of the hand grip is fixedly connected to the side of the moving block. The purpose is to ensure that the moving block can automatically reset and reduce manual intervention.

[0013] A return spring is fixedly connected inside the fixing clamp. The end of the return spring away from the inner wall of the fixing clamp is fixedly connected to the circumferential surface of the hydraulic rod. The purpose of this is to ensure that the hydraulic rod can automatically reset and reduce manual intervention.

[0014] The number of connecting rods, hydraulic rods and return springs is set to two, and they are symmetrical to each other along the vertical central axis of the connecting handle. The inner side of the fixing clamp has a storage groove, and the side of the adjusting plate is slidably connected to the inside of the storage groove. The purpose is to stably clamp the two sides of the housing and improve the stability of removal.

[0015] One end of the force-bearing rod is located on the displacement trajectory of the trigger block. The initial states of the compression spring and the return spring are both set to the relaxed state, which is to ensure that the movement of the trigger block can compress the force-bearing rod.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] 1. In this utility model, through the cooperation between components such as the micro motor, cooling box, and circulation pipe of the cooling mechanism, when it is necessary to remove the inner shell of the furnace, the operator holds the hand handle, starts the micro motor to drive the rotating shaft, drives the half gear to rotate, moves the extrusion plate through the rack, squeezes the coolant into the delivery main pipe and flows into the circulation pipe. When the half gear rotates to the toothless area, the rack separates from it, and is reset by the spring. The rack continues to reciprocate to supply coolant. The used coolant returns to the cooling box through the return pipe and one-way valve, realizing the circulation and cooling of the shell removal tool. This design achieves the effect of cooling the shell removal tool, ensuring continuous and stable operation in the high-temperature furnace environment and extending its service life.

[0018] 2. In this utility model, through the cooperation between components such as the moving block, hydraulic cylinder, and storage groove of the clamping mechanism, the operator presses the moving block, which drives the trigger block to squeeze the force rod. The hydraulic cylinder pushes the hydraulic rod out through hydraulic pressure, which drives the adjustment plate to clamp the inner shell of the furnace. After the moving block is released, the reset spring causes the trigger block and adjustment plate to automatically reset and release the clamp. This design achieves the effect of clamping and removing shells of different sizes, ensuring the accuracy and efficiency of clamping and releasing the shell. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-5 As shown, it illustrates a furnace shell removal device according to an embodiment of the present invention, including a connecting handle 1, a hand grip 2 fixedly connected to the top end of the connecting handle 1, a fixing clamp 3 fixedly connected to the bottom end of the connecting handle 1, and a cooling mechanism 4 provided inside the connecting handle 1.

[0033] The cooling mechanism 4 includes a mounting plate 41 and a micro motor 42. The side of the mounting plate 41 is fixedly connected to the inner wall of the connecting handle 1. The side of the mounting plate 41 is fixedly connected to the side of the micro motor 42. The output end of the micro motor 42 is fixedly connected to a rotating shaft 43. A half gear 44 is fixedly passed through the circumferential surface of the rotating shaft 43. A sliding groove 45 is opened inside the connecting handle 1. A rack 46 is slidably connected inside the sliding groove 45. A moving column 47 is fixedly connected to the side of the rack 46. A cooling box 48 is fixedly connected inside the connecting handle 1. The circumferential surface of the moving column 47 passes through and is slidably connected to the side of the cooling box 48. An extrusion plate 49 is slidably connected inside the cooling box 48. The side of the extrusion plate 49 is fixedly connected to one end of the moving column 47. A conveying main pipe 410 is fixedly passed through the side of the cooling box 48. A circulation pipe 411 is fixedly connected to the circumferential surface of the conveying main pipe 410.

[0034] In some examples, a tension spring 412 is fixedly connected to the inner wall of the connecting handle 1. The end of the tension spring 412 away from the inner wall of the connecting handle 1 is fixedly connected to the side of the rack 46. The purpose is to ensure that the rack 46 can automatically reset when it is separated from the half gear 44, reducing manual intervention.

[0035] One end of the circulation pipe 411 is fixedly connected to the return pipe 413. The end of the return pipe 413 away from the circulation pipe 411 is fixedly connected to the side of the cooling box 48. A one-way valve 414 is provided on the circumferential surface of the return pipe 413. Its purpose is to ensure that the used cooling water can be circulated through the return pipe 413 to maintain the stability of the coolant.

[0036] The fixing clamp 3 is made of silicon carbide fiber reinforced ceramic matrix composite material, the fixing clamp 3 has a temperature resistance of 1,600 degrees Celsius, the circulation tube 411 is spiral in shape, and the channel diameter of the circulation tube 411 is 1.5 mm.

[0037] The circumferential surface of the half gear 44 meshes with the side of the rack 46. The number of circulation pipes 411 is set to two, and they are symmetrical about each other along the vertical central axis of the cooling box 48. The purpose is to ensure that the rotation of the half gear 44 can drive the rack 46 to move, and the two ends of the fixed clamp 3 are cooled simultaneously through the two circulation pipes 411.

[0038] For example, such as Figures 1-5 As shown, when it is necessary to remove the shell inside the furnace, the operator holds the hand handle 2, which activates the micro motor 42. The output end of the micro motor 42 rotates, driving the rotating shaft 43 to rotate. The rotating shaft 43 drives the half gear 44 to rotate. Through the meshing of the half gear 44 and the rack 46, the rotation of the half gear 44 causes the rack 46 to move inside the slide groove 45. The movement of the rack 46 drives the extrusion plate 49 to move inside the cooling box 48 via the moving column 47. The movement of the extrusion plate 49 moves the cooling box 48. The coolant is squeezed, causing it to enter the main delivery pipe 410 and then the circulation pipe 411. When the half gear 44 rotates to the toothless area, the rack 46 separates from the half gear 44 and is reset by the elasticity of the tension spring 412. The continuous rotation of the half gear 44 causes the rack 46 to reciprocate linearly, thereby continuously supplying coolant to the cooling box 48. The used coolant flows back to the cooling box 48 through the return pipe 413 and the one-way valve 414, continuously cooling the shell-picking tool.

[0039] like Figures 1-5As shown, this invention illustrates a furnace shell removal device in another embodiment, which is largely the same as the above-described technical solution. Therefore, only the differences are described. The device includes a clamping mechanism 5, which includes an inlay groove 51. The inlay groove 51 is located inside the hand grip 2. A moving block 52 is slidably connected inside the inlay groove 51. A connecting rod 53 is fixedly connected to the bottom of the moving block 52. A trigger block 54 is fixedly connected to the end of the connecting rod 53 away from the bottom of the moving block 52. A hydraulic cylinder 55 is fixedly connected inside the fixing clamp 3. A force rod 56 is slidably connected to one end of the hydraulic cylinder 55 via a piston. A hydraulic rod 57 is driven by the hydraulic cylinder 55. An adjusting plate 58 is fixedly connected to the end of the hydraulic rod 57 away from the side of the hydraulic cylinder 55. The purpose of this device is to clamp and remove shells of different sizes.

[0040] In some examples, a compression spring 59 is fixedly connected to the inner wall of the hand grip 2, and one end of the compression spring 59 away from the inner wall of the hand grip 2 is fixedly connected to the side of the moving block 52. The purpose of this is to ensure that the moving block 52 can automatically reset and reduce manual intervention.

[0041] A return spring 510 is fixedly connected inside the fixed clamp 3. The end of the return spring 510 away from the inner wall of the fixed clamp 3 is fixedly connected to the circumferential surface of the hydraulic rod 57. The purpose is to ensure that the hydraulic rod 57 can automatically reset and reduce manual intervention.

[0042] The number of connecting rod 53, hydraulic rod 57 and return spring 510 is set to two, and they are symmetrical to each other along the vertical central axis of connecting handle 1. The inner side of the fixing clamp 3 has a storage groove 511. The side of the adjusting plate 58 is slidably connected to the inside of the storage groove 511. The purpose is to stably clamp the two sides of the housing and improve the stability of removal.

[0043] One end of the force rod 56 is located on the displacement trajectory of the trigger block 54. The initial states of the compression spring 59 and the return spring 510 are both set to the relaxed state. The purpose is to ensure that the movement of the trigger block 54 can compress the force rod 56.

[0044] For example, such as Figures 1-5As shown, when the worker uses the fixing clamp 3 to clamp the shell inside the furnace, for shells of different sizes, the worker presses the moving block 52, causing the moving block 52 to move inside the inlay groove 51. The movement of the moving block 52 drives the trigger block 54 to move through the connecting rod 53. The movement of the trigger block 54 compresses the force rod 56, causing the force rod 56 to retract into the hydraulic cylinder 55. At this time, the hydraulic rod 57 extends outward under the pressure of the liquid inside the hydraulic cylinder 55. The movement of the hydraulic rod 57 drives the adjusting plate 58 to move, thereby clamping and removing the shell inside the furnace. At this time, the worker releases the moving block 52, and the moving block 52 drives the trigger block 54 to automatically reset through the return spring 510, thereby causing the adjusting plate 58 to reset to the inside of the receiving groove 511 through the return spring 510, releasing the clamping of the shell.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
