Description

Technical Field

[0001] The utility model relates to the technical field of lead casting equipment, in particular to a base of a disc ingot casting reducer. Background Technique

[0002] At present, during the lead ingot casting process, disc ingot casting is mostly adopted. The base of the existing disc ingot casting reducer usually uses concrete casting, and the base is fixed to the concrete foundation through embedded bolts. As the production time increases, the embedded bolts of the ingot casting reducer base vibrate for a long time, and the bolts will become loose or even break, affecting the normal operation of the ingot casting reducer. Moreover, during the process of water cooling and temperature reduction of the cast lead ingot, the generated water vapor will exacerbate the corrosion of the bolts, causing further damage to the bolts and affecting the lead casting operation.

[0003] Since the fixing bolts are installed at the bottom of the disc ingot casting reducer, due to structural limitations, most bolts cannot be conveniently maintained. The vibration generated during the operation of the ingot casting reducer and the water vapor generated during the water cooling and temperature reduction of the cast lead ingot will cause the fixing bolts to become loose and corroded. The force borne by the loose fixing bolts will be transmitted to other fixing bolts, causing the other well-conditioned fixing bolts to become further loose and break, having a greater impact on the lead casting operation. Summary of the Invention

[0004] The utility model provides a base of a disc ingot casting reducer to solve the problems that the base bolts of the existing disc ingot casting reducer are prone to looseness and difficult to maintain, which can reduce the probability of the embedded bolts breaking, and repair the damaged base of the embedded bolts of the existing disc ingot casting reducer without replacing the existing embedded bolts.

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0006] A base of a disc ingot casting reducer includes an embedded base and embedded bolts. An installation frame, a fixing frame and an installation steel plate are sequentially arranged between the reducer and the embedded base. The installation frame is located below the reducer body and is used to fix the reducer. The fixing frame is used to connect the installation frame and the installation steel plate. The bottom end of the embedded bolt is located in the embedded base, and the top end is fixedly connected to the installation steel plate. A casting part is filled between the installation steel plate and the embedded base. The embedded base can adopt the base of the disc ingot casting reducer in the prior art.

[0007] Further, the installation frame has a box structure with an open side, and the transmission gear at the end of the reducer shaft head is located inside the box of the installation frame. The installation frame is used to fix the reducer.

[0008] Further, a notch is provided at the top of the installation frame corresponding to the open side of the box, and the width of the notch is greater than the diameter of the reducer shaft head. The reducer after the transmission gear is assembled can be horizontally pushed in.

[0009] Further, the upper top surface of the fixing frame is parallel to the lower bottom surface, and a supporting vertical plate is arranged between the upper top surface and the lower bottom surface. The fixing frame is used to fix the mounting frame and the mounting steel plate.

[0010] Further, the cross section of the mounting steel plate is in an inverted trapezoid shape, and holes are formed in the mounting steel plate corresponding to the positions of the embedded bolts. After the embedded bolts are inserted into the mounting steel plate, they are fixedly connected to the mounting steel plate, increasing the contact area between the embedded bolts and the mounting steel plate.

[0011] Further, a rectangular or inverted trapezoidal pouring groove is formed on the upper surface of the embedded base, and the mounting steel plate and the pouring part are arranged in the pouring groove. The pouring part fills the gap between the mounting steel plate and the pouring groove.

[0012] Further, a ventilation hole is formed at the center of the mounting steel plate. The pouring part is in full contact with the bottom surface of the mounting steel plate.

[0013] Further, the lower end of the embedded bolt is in an inverted hook shape. The connection between the lower end of the embedded bolt and the embedded base is made more firm.

[0014] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0015] 1. Holes are correspondingly formed in the mounting steel plate at the positions corresponding to the embedded bolts. The mounting steel plate is placed through the embedded bolts in the pouring groove, and then the upper part of the embedded bolts and the mounting steel plate are fixedly connected. When pouring, the grouting material is poured from the periphery of the mounting steel plate, and the grouting material emerges through the ventilation holes in the middle of the mounting steel plate, enabling firm pouring.

[0016] 2. The lower half of the embedded bolt is fixedly installed in the embedded base, and the lower end of the embedded bolt is in an inverted hook shape. The upper half of the embedded bolt is fixedly connected to the mounting steel plate by perforation welding. The inverted hook-shaped embedded bolt can make the connection between the embedded bolt and the embedded base more firm. After the mounting steel plate is connected to the fixing frame, the vibration generated by the ingot reducer can be transmitted to the embedded base.

[0017] 3. A notch is provided at the top of the mounting frame corresponding to the opening side of the box body, facilitating the horizontal installation of the ingot vertical reducer, effectively solving the problem of the vertical downward installation of the embedded transmission gear, and being a powerful guarantee for strengthening the strength of the overall frame base.

[0023] The present utility model will be further described below in conjunction with the attached drawings and specific embodiments:

[0024] Embodiment 1

[0025] As Figures 1 to 4 shown, this embodiment provides a base for a disk ingot speed reducer, which is located below the body of the speed reducer 1 and includes a mounting frame 2, a fixing frame 4, an installation steel plate 8, an embedded bolt 5, a pouring part 7, and an embedded base 6.

[0026] The embedded base 6 is cast with concrete. The lower part of the embedded bolt 5 is fixedly arranged in the embedded base 6. An installation frame 2, a fixing frame 4, and an installation steel plate 8 are sequentially arranged between the speed reducer 1 and the embedded base 6. The installation frame 2 is located below the body of the speed reducer 1 and is used to fix the speed reducer 1. The fixing frame 4 is used to connect the installation frame 2 and the installation steel plate 8. The bottom end of the embedded bolt 5 is located in the embedded base 6, and the top end is fixedly connected to the installation steel plate 8. A pouring part 7 is filled between the installation steel plate 8 and the embedded base 6.

[0027] As Figure 2 shown, the installation frame 2 has a box structure with an open side. The top of the installation frame 2 is provided with a top plate, and a circular hole is opened on the top plate. An annular groove is opened around the circular hole. The circular hole and the annular groove together form a stepped installation opening. The speed reducer 1 is located in the annular groove, and the shaft head of the speed reducer 1 passes through the circular hole. The transmission gear 3 at the end of the shaft head of the speed reducer 1 is located inside the box body of the installation frame 2. For the convenience of installation, as an implementable way, a notch is provided on one side of the installation opening at the top of the installation frame 2 corresponding to the opening of the box body. The width of the notch is greater than the diameter of the shaft head of the speed reducer 1, and it can just pass through the shaft head of the speed reducer 1. The speed reducer 1 after the transmission gear 3 is assembled can be horizontally pushed in and placed on the installation frame 2.

[0028] The upper surface of the fixing frame 4 is parallel to the lower surface, and a support vertical plate is arranged between the upper surface and the lower surface. The upper surface of the fixing frame 4 has the same shape and size as the bottom surface of the mounting frame 2. The fixing frame 4 and the mounting frame 2 are connected by bolts. After the bolts between the fixing frame 4 and the mounting frame 2 are tightened, the fixing frame 4 and the mounting frame 2 can also be fixed together by spot welding, so as to make the connection between the fixing frame 4 and the mounting frame 2 stable.

[0029] The lower bottom surface of the fixing frame 4 is fixedly connected with the mounting steel plate 8 through the embedded bolt 5 (as Figures 1 to 3 shown), or the lower bottom surface of the fixing frame 4 is directly welded to the mounting steel plate 8 (as Figure 4 shown). Holes are opened at the positions corresponding to the embedded bolts 5 on the mounting steel plate 8. The embedded bolts 5 are flush with or penetrate through the mounting steel plate 8. The mounting steel plate 8 is made of 304 stainless steel to increase the corrosion resistance of the mounting steel plate 8. The cross-section of the mounting steel plate 8 is trapezoidal in reverse. In order to make the mounting steel plate 8 fit better with the pouring part 7, a ventilation hole is opened at the center of the mounting steel plate 8. The ventilation hole enables the grouting material to fully contact the bottom surface of the mounting steel plate and be more firmly attached after solidification.

[0030] A rectangular or trapezoidal pouring groove is opened on the upper surface of the embedded base 6. The mounting steel plate 8 and the pouring part 7 are arranged in the pouring groove. During actual use, first, the drilled mounting steel plate 8 is sleeved on the upper half of the embedded bolt 5 and welded, and then poured from the periphery of the mounting steel plate 8. After the grouting material solidifies, the pouring part 7 is formed. Since there are ventilation holes on the mounting steel plate 8, the grouting material emerges through the ventilation holes in the middle of the mounting steel plate, and firm pouring can be realized, so that the connection between the mounting steel plate 8, the embedded base 6 and the embedded bolt 5 is closer.

[0031] In order to make the connection between the embedded bolt 5 and the embedded base 6 stable and prevent the embedded bolt 5 from loosening, the lower end of the embedded bolt 5 is shaped like an inverted hook. Figure 3 The shown is an embedded bolt with an inverted hook shape. Figure 2 The shown is a conventional embedded bolt.

[0032] During installation, first, the embedded base 6 and the embedded bolt 5 are poured together. After the grouting material solidifies and compacts, the mounting steel plate 8 is sleeved on the upper part of the embedded bolt 5, and then the mounting steel plate 8 and the embedded bolt 5 are welded together. The grouting material is poured into the pouring groove from around the mounting steel plate 8. A firm pouring part 7 is formed between the mounting steel plate 8 and the embedded base 6. Position the fixing frame 4, fix the bottom surface of the fixing frame 4 to the mounting steel plate 8, adjust the position of the mounting frame 2, tighten the positioning bolts between the fixing frame 4 and the mounting frame 2, and then fix the fixing frame 4 and the mounting frame 2 together by spot welding, thus completing the installation of the base of the disk ingot reducer.

[0033] Embodiment 2

[0034] The utility model can be used for transforming the base of a disc ingot casting reducer in the prior art. When the embedded bolts 5 are broken, the base can be repaired without replacing the embedded bolts.

[0035] As Figure 4 shown, a casting groove with a depth of 80 mm is chiseled downward on the concrete foundation surface under the base of the reducer 1. The casting groove is rectangular or inverted trapezoidal. Figure 4 As shown in [the figure] as a rectangular casting groove, all the broken embedded bolts 5 are found, corresponding holes for the embedded bolts 5 are drilled on the mounting plate 8, the mounting plate 8 is passed through all the embedded bolts 5, and the parts of the embedded bolts 5 above the mounting plate 8 are all cut off; after adjusting the mounting position between the upper surface of the mounting plate 8 and the lower surface of the fixing frame 4, the upper part of the embedded bolt 5 is welded to the mounting plate 8; after the secondary grouting solidifies to form the casting part 7, after the reducer 1 is positioned, the fixing frame 4 is welded to the mounting plate 8. After the positioning bolts between the fixing frame 4 and the mounting frame 2 are tightened, the fixing frame 4 and the mounting frame 2 are spot-welded together, thoroughly solving the problems of corrosion, breakage, and loosening of the embedded bolts of the reducer base, and restoring the reliable and stable rotation performance of the reducer base.

[0036] The above embodiments are only the preferred embodiments of the utility model, and do not limit the scope of implementation of the utility model. Therefore, all equivalent changes or modifications made according to the structure, features, and principles described in the scope of the utility model patent should be included in the scope of the utility model patent application.
