Description

Technical Field

[0001] The utility model relates to the technical field of ladle accessories, and more specifically, to a bidirectional ladle cover adding and uncovering mechanism. Background Art

[0002] In order to reduce the heat loss of molten steel caused by necessary stagnation during the production process, a ladle cover for insulation is usually added to the ladle loaded with molten steel. The ladle cover is generally connected to the ladle at one end with a self-locking mechanism, and the other end covers the top of the ladle. The covering and uncovering actions of the ladle cover need to be completed by a special covering and uncovering mechanism. The principle is to complete the lifting and storage actions by gear-jointing the ring seat on the top of the ladle cover, so that the ladle cover leaves the ladle. Similarly, when transporting the ladle in the reverse direction, the butt end of the ladle and the end of the ladle cover with a self-locking mechanism automatically dock, and drive the ladle cover to disengage from the covering and uncovering mechanism, completing the cover withdrawal and lowering actions, and the ladle cover covers the top of the ladle again to meet the needs of the production process.

[0003] However, this mode has several disadvantages: first, the lid adding and uncovering action is completed by only a pair of splines, and the ladle cover is not stable enough during the transfer process and in the stored state, and there is a risk of the ladle cover falling; second, the ladle must be transported in a specified direction, that is, it can only be transported in one direction, which has a great impact on the entire production line. It may be necessary to set up more lid adding and uncovering devices or add additional transmission processes to realize the planned lid adding and uncovering action; third, when the ladle cover is stored on the lid adding and uncovering device, the overturning angle is too large, which poses a great safety hazard and also affects the stability of the lid adding and uncovering action. Utility Model Content

[0006] A two-way ladle cover-adding and uncovering mechanism comprises a main frame, wherein at least two groups of double-headed teeth are arranged on the top of the main frame, and the two groups of double-headed teeth are arranged opposite to each other on the left and right, wherein the double-headed teeth of one group are located between the double-headed teeth of the other group, and the ladle cover is hooked on the same side of the double-headed teeth of different groups through at least two groups of ring seats.

[0012] Furthermore, the non-slope sections of the bend insert and the mating insert are independently rotatably and adjustably connected to the main frame, and the bend insert and the mating insert are fixed relative to the main frame via a locking member.

[0013] Furthermore, the non-slope sections of the make-up insert and the mating insert in the same group are coaxially aligned and connected to the main frame.

[0014] Furthermore, the bottom ends of the slope sections of the buckle insert and the matching insert are cut flat and are at the same level, and the matching insert that is not butted against the ring seat also contacts the top of the ladle cover.

[0015] Furthermore, the slope section of the matching insert has a concave arc or angle, and the matching insert involved in opening the cover contacts the corresponding ring seat surface.

[0025] Example:

[0026] The following is combined with Figure 1-3 The utility model is described in further detail.

[0027] Two-way ladle cover mechanism, such as Figure 1 As shown, the main body is the main frame 1, which is modified from the original cover-covered gear-slotting installation tower, and the left and right horizontal directions are recorded as the incoming material direction. Two front-to-back symmetrical mounting seats are set at the left end of the main frame 1, and two front-to-back symmetrical mounting seats are also set at the right end of the main frame 1. The two mounting seats on the left are located between the two mounting seats on the right in the front-to-back direction as a whole, that is, the mounting seats on both sides will form a misalignment. Two groups of double-headed gears 2 are installed on the mounting seats, and the two groups of double-headed gears 2 are arranged opposite to each other. In this way, the two groups of double-headed gears 2 are also correspondingly misaligned. The ring seat 7 of the ladle cover 6 is correspondingly hooked on the same side of different groups of double-headed gears 2. It should be noted that because the gear is designed as a double-headed structure, the self-locking end of the ladle cover 6 should not be set as a lock groove structure with a return ring, and it is preferably set as a vertical lock groove, so as not to affect the hooking action in the forward and reverse directions.

[0028] The double-headed spline 2 includes an upper spline 3 and a matching spline 5. One end of the upper spline 3 is a slope structure, and the other end is butted against the main frame 1. An inward-recessed slot 4 is provided at the top of the slope structure, and the innermost side of the slot 4 has a loop structure, which is convenient for locking the ring seat 7 of the ladle cover 6 later. One end of the matching spline 5 is also a slope structure, and the other end is also butted against the main frame 1. The upper spline 3 and matching spline 5 of the same group have slope sections facing each other. The difference between the matching spline 5 and the upper spline 3 is that the slope of the matching spline 5 is much lower than that of the upper spline 3, which can increase fault tolerance. Even if the ring seat 7 near the self-locking end of the ladle cover 6 contacts the matching spline 5 first, the ring seat 7 at the other end can be quickly lifted after contacting the upper spline 3, and the main force point is transferred to the side of the upper spline 3 with the slot 4. More preferably, the slope section of the mating insert 5 has an inwardly concave arc or angle, and the curvature is about 3-5 degrees, which plays a certain role in preventing falling and does not affect the normal docking with the ring seat 7. The left double-head insert 2 is installed according to the left upper insert 3 and the right mating insert 5; the right double-head insert 2 is installed according to the left mating insert 5 and the right upper insert 3.

[0029] There are two designs for the double-ended spline 2: one is to directly design the upper spline 3 and the mating spline 5 into an integrally formed structure, and the butt ends of the two splines are connected to form a new butt end, which is installed on the main frame 1. The other is to set the upper spline 3 and the mating spline 5 separately, and the butt ends of the two splines are provided with corresponding mounting holes. The mounting holes can be aligned and installed on the same mounting seat, or similar mounting seats can be added and installed in different corresponding positions. The former is coaxially adjusted, and the latter is adjusted separately, both of which are to fine-tune the misalignment of the butt accuracy with the ladle cover 6 caused by normal wear and tear under long-term use. In addition, no matter which structure of the double-ended spline 2 is selected, it is necessary to install additional locking parts and strengthen the fixation with the main frame 1.

[0030] The bottom ends of the slope sections of the upper bend insert 3 and the matching insert 5 are cut flat, that is, the bottom ends are set to be flat and set at the same height. The flat bottom surface facilitates the subsequent contact and limit of the matching insert 5 on the other side that does not directly participate in the hooking to the top surface of the ladle cover 6. Setting them at the same height ensures that the tilt angle of the ladle cover 6 is basically zero after the cover is opened.

[0031] Two sets of ring seats 7 are also provided on the top of the ladle cover 6, and the ring seats 7 are provided corresponding to the double-headed spline 2. A suitable bearing can be provided in the insertion hole of the ring seat 7 to reduce friction and loss during insertion. The height of the ring seat 7 on the self-locking end of the ladle cover 6 should be greater than or equal to that of the ring seat 7 on the other side, because when the cover is opened, the ladle and the ladle cover 6 are fed in together, and the material is generally fed in the manner of the self-locking end of the ladle cover 6 in front, so the spline 5 must first meet the ring seat 7. In order to ensure that the main force point is placed on the side of the upper spline 3, the height difference of the ring seats 7 on both sides can be appropriately adjusted to adapt.

[0032] like Figure 2 As shown, the ladle and the ladle cover 6 are transmitted from right to left and approach the main frame 1, with the self-locking end of the ladle cover 6 in front and at the left end. The ring seat 7 at the left end of the ladle cover 6 first merges with the matching tooth 5 in the double-headed tooth 2 on the left side of the main frame 1. As the transmission progresses, the ring seat 7 at the right end of the ladle cover 6 also merges with the upper beading tooth 3 in the double-headed tooth 2 on the right side of the main frame 1, and is lifted along the slope section, leaving the ladle, completing the lid opening action. The ring seat 7 of the ladle cover 6 is mainly hooked in the slot 4 of the upper beading tooth 3 and will not be separated in normal state. The other end of the ring seat 7 is in surface contact with the matching tooth 5 of the double-headed tooth 2 of different groups, and the matching tooth 5 of the double-headed tooth 2 of the same group also conflicts with the top surface of the ladle cover 6, forming a relatively stable triangular structure. The inclination angle of the ladle cover 6 is within a more reasonable range, and the reliability is better. The lidding operation is the same as the conventional process, and the ladle and the ladle cover 6 can be transmitted in reverse.

[0033] like Figure 3As shown, the ladle and the ladle cover 6 start to be transferred from left to right and approach the main frame 1. The ring seat 7 at the right end of the ladle cover 6 first merges with the matching slotting gear 5 in the double-headed slotting gear 2 on the right side of the main frame 1. As the transfer progresses, the ring seat 7 at the left end of the ladle cover 6 also merges with the upper snap-on slotting gear 3 in the double-headed slotting gear 2 on the left side of the main frame 1, and the lid is lifted and the lid opening action is completed. The number of lid opening equipment in the workshop and the space occupied can be reduced, and the same lid opening mechanism can be used to operate with ladles of different processes and transmission lines, which has better applicability.

[0034] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
