Electroslag casting of special-shaped parts is unique, and annual domestic electroslag steel production has reached hundreds of thousands of tons. Electroslag furnaces are essential production equipment for specialty steel mills. However, the mold and base were previously connected using 12 bolts. Aligning and installing the bolt holes required a significant number of operators and auxiliary man-hours, making installation and disassembly difficult and time-consuming. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, such as: in the past, the installation of the crystallizer and the base was connected by 12 bolts, the centering and installation of the bolt holes would occupy a large number of operators and generate a large amount of auxiliary man-hours, the installation and disassembly were difficult and time-consuming, and a quick installation structure for the electroslag furnace crystallizer was proposed.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Example 1:

[0026] Reference Figure 1-7 , a rapid installation structure of an electroslag furnace crystallizer, including a crystallizer body 1, a mounting plate 2 is fixedly connected to the surface of the crystallizer body 1, the upper surface of the mounting plate 2 and the surface of the crystallizer body 1 are fixedly connected with reinforcing ribs 9, and the mounting plate 2 and the crystallizer body 1 are fixedly fixed with reinforcing ribs 9. The reinforcing ribs 9 make the fixing between the mounting plate 2 and the crystallizer body 1 more firmly. A through hole 3 is opened inside the mounting plate 2, and a positioning ring 4 is fixedly connected to the inner wall of the through hole 3. A positioning pin 5 is fitted on the inner wall of the positioning ring 4, and a base 6 is fixedly connected to the surface of the positioning pin 5. When the positioning ring 4 is sleeved on the positioning pin 5, the crystallizer body 1 placed on the base 6 is positioned by the cooperation of the positioning pin 5 and the positioning ring 4. A card hole 7 is opened inside the positioning pin 5, and a wedge pin 8 is fitted on the inner wall of the card hole 7, the surface of the positioning ring 4 and the front and back sides of the positioning pin 5.

[0027] The wedge pin 8 includes a strip column 801. The inner wall of the card hole 7 and the upper surface of the positioning ring 4 are in contact with the surface of the strip column 801. The upper surface of the strip column 801 is provided with a groove 802. The inner wall of the groove 802 is fitted with a U-shaped column 803. The front and rear sides of the positioning pin 5 are in contact with the inner wall of the U-shaped column 803. The bottom of the U-shaped column 803 and the inner wall of the groove 802 are fixedly connected with a first spring 804. The U-shaped column 803 is pressed against the first spring 804. The support is provided so that the inner wall of the U-shaped column 803 cannot be automatically separated after contacting the positioning pin 5. A strip hole 805 is provided inside the U-shaped column 803, and a limiting column 806 is fitted on the inner wall of the strip hole 805. The left and right ends of the limiting column 806 are fixedly connected to the inner wall of the groove 802. Through the cooperation of the limiting column 806 and the strip hole 805, the U-shaped column 803 cannot be separated from the groove 802, and the moving trajectory of the U-shaped column 803 is guided.

[0028] Example 2:

[0029] Reference Figure 1-3 The front and rear sides of the U-shaped column 803 are fixedly connected with a trapezoidal block 10. The upper surface of the trapezoidal block 10 is an inclined surface. When the bar column 801 is inserted into the card hole 7 and the bar column 801 is pushed horizontally, the inclined surface on the trapezoidal block 10 can make the U-shaped column 803 automatically move downward during the movement of the bar column 801, so that the user does not need to pinch the U-shaped column 803 with his hands when inserting the bar column 801 into the card hole 7.

[0030] Example 3:

[0031] Reference Figure 1-8 A stepped hole 11 is provided inside the U-shaped column 803, and a bolt 12 is fitted on the inner wall of the stepped hole 11. A nut 13 is threadedly connected to the surface of the bolt 12, and the upper surface of the nut 13 is fixedly connected to the bottom of the U-shaped column 803. A second spring 14 is fixedly connected to the bottom of the bolt 12. The center of the bolt 12 is on the same vertical line as the center of the second spring 14. The diameter of the bolt 12 is larger than the diameter of the second spring 14. The bottom of the second spring 14 contacts the inner wall of the groove 802. Through the cooperation of the bolt 12 and the nut 13, the second spring 14 can be fixed to the U-shaped column 803. At the same time, when the elasticity of the first spring 804 decreases due to aging, the second spring 14 can be fixed to the U-shaped column 803 so that the wedge pin 8 can still be in close contact with the positioning pin 5 after being inserted into the card hole 7. Further, when the elasticity of the first spring 804 decreases due to aging, the wedge pin 8 can continue to be used by adding the second spring 14 to the U-shaped column 803.

[0032] In the present invention, when the user uses the device, first install the base 6 at the designated position, then place the crystallizer body 1 with the positioning ring 4 on the base 6, and put the positioning ring 4 on the positioning pin 5. At this time, the crystallizer body 1 on the base 6 is positioned by the cooperation of the positioning pin 5 and the positioning ring 4.

[0033] Then, insert the strip column 801 into the clamping hole 7 and push the strip column 801 horizontally. At this time, the U-shaped column 803 can automatically move downward during the movement of the strip column 801 through the inclined surface on the trapezoidal block 10. When the inner wall of the U-shaped column 803 is aligned with the positioning pin 5, the elastic force of the first spring 804 can make the U-shaped column 803 move upward and make the inner wall of the U-shaped column 803 contact the surface of the positioning pin 5. At this time, the strip column 801 is clamped in the clamping hole 7 through the cooperation of the U-shaped column 803 and the positioning pin 5, and the positioning ring 4 is fixed on the positioning pin 5 through the cooperation of the clamping hole 7 and the strip column 801. At this time, the crystallizer body 1 can be fixed on the base 6 through the cooperation of the positioning ring 4 and the positioning pin 5.

[0034] When the crystallizer body 1 needs to be disassembled, first pinch the U-shaped column 803 and the strip column 801 to separate the U-shaped column 803 from the positioning pin 5. Then, by removing the strip column 801 from the clamping hole 7, the positioning ring 4 can be separated from the positioning pin 5. At this time, the crystallizer body 1 can be separated from the base 6 by moving the crystallizer body 1 upward.
