The front hinge shaft of the ladle cover is connected to the position of the anti-falling inclined angle in the middle of the lifting insertion tooth, and through the lifting movement of the lifting insertion tooth, the covering and uncovering of the ladle cover on the ladle are realized.
[0003] However, in the case where the setting angle of the lifting insertion tooth is inappropriate or the front hinge shaft of the ladle cover is not completely set at the position of the anti-falling inclined angle in the middle of the lifting insertion tooth, the ladle cover may still fall off the lifting insertion tooth. Utility Model Content
[0004] This application aims to at least solve the technical problem of the ladle cover falling off the lifting insertion tooth to a certain extent. For this purpose, this application provides a ladle cover adding and removing device.
[0005] The technical solution of this application is as follows:
[0006] This application provides a ladle cover adding and removing device, which includes:
[0007] A frame;
[0008] A lifting insertion tooth, which is liftably arranged on the frame;
[0009] A safety pin, which is vertically movably inserted into the frame. The bottom end of the safety pin corresponds to the top of the front end of the lifting insertion tooth, and the stroke of the safety pin is less than the stroke of the lifting insertion tooth.
[0010] In some embodiments, the ladle cover adding and removing device further includes a bracket, which is arranged on the frame, and the safety pin is movably inserted into the bracket.
[0011] In some embodiments, the ladle cover adding and removing device further includes a sleeve, which is vertically penetrated through the bracket, and the safety pin is penetrated through the bracket;
[0012] An annular protrusion is provided at the top end of the safety pin, and the outer diameter of the annular protrusion is greater than the inner diameter of the sleeve.
[0013] In some embodiments, the safety pin is in clearance fit with the sleeve.
[0014] In some embodiments, the diameter of the safety pin is 88 mm to 108 mm, the length of the safety pin is 850 mm to 900 mm, and the length of the sleeve is 410 mm to 460 mm.
[0015] In some embodiments, the bracket is provided with mounting holes, the sleeve is disposed in the mounting holes, flanges are provided at both ends of the sleeve, and the flanges are connected to the bracket.
[0016] In some embodiments, the flanges at both ends of the sleeve are welded to the bracket.
[0017] In some embodiments, the bottom end of the safety pin is spherical.
[0018] In some embodiments, the ladle cover lifting and removing device further includes a lifting ring, and the lifting ring is disposed at the top end of the safety pin.
[0019] In some embodiments, the lifting ring is screwed to the safety pin.
[0020] The embodiments of the present application at least have the following beneficial effects:
[0021] The present application provides a ladle cover lifting and removing device. The frame provides an installation basis for the lifting rack and the safety pin. By installing the lifting rack and the safety pin on the frame, the lifting rack and the safety pin are arranged on the ladle cover lifting and removing device. The lifting rack is used to be inserted into the front hinge shaft of the ladle cover, and through the lifting movement of the lifting rack, the ladle cover is covered and removed on the ladle. The safety pin is used to block the ladle cover arranged on the lifting rack, so that when the ladle cover falls off the lifting rack, the safety pin blocks the ladle cover, thereby reducing the risk of the ladle cover falling off the lifting rack.
[0022] Since the bottom end of the safety pin is correspondingly arranged with the top of the front end of the lifting rack, the stroke of the safety pin is less than the stroke of the lifting rack. Thus, when both the safety pin and the lifting rack are at the lowest point, there is a gap between the bottom end of the safety pin and the top of the front end of the lifting rack. At this time, the lifting rack is inserted into the front hinge shaft of the ladle cover, avoiding interference between the safety pin and the ladle cover. When the lifting rack drives the ladle cover to move upward from the lowest point, the lifting rack moves to the position where it contacts the bottom end of the safety pin, and then drives the safety pin to continue moving upward until it moves to the highest point of the lifting rack. At this time, the safety pin is also at the highest point. It should be noted that the highest point of the safety pin refers to the maximum height that the lifting rack can lift the safety pin to, and during this process, the safety pin remains abutted against the lifting rack. In this way, the ladle cover is removed from the ladle, and vice versa, the ladle cover is placed on the ladle.
[0023] When the lifting gear shaper is inserted into the front hinge shaft of the ladle cover, the front hinge shaft of the ladle cover is arranged at the position of the anti-falling bevel angle in the middle of the lifting gear shaper. The rear end of the lifting gear shaper is connected to the machine frame, and the front end of the lifting gear shaper is a suspended end. The lifting gear shaper is inserted into the front hinge shaft of the ladle cover along the direction from the front end to the rear end, and the direction in which the ladle cover falls off the lifting gear shaper is from the rear end to the front end of the lifting gear shaper. Therefore, when the lifting gear shaper contacts the safety pin, the bottom end of the safety pin is kept abutted against the top of the front end of the lifting gear shaper. When the ladle cover falls off the lifting gear shaper, the front hinge shaft of the ladle cover moves from the middle of the lifting gear shaper to the front end of the lifting gear shaper, and the bottom end of the safety pin abutted against the top of the front end of the lifting gear shaper blocks the front hinge shaft of the ladle cover, thereby reducing the risk of the ladle cover falling off the lifting gear shaper and improving the safety of the ladle cover adding and removing device.

Such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.
[0033] The present application will be described below in conjunction with the accompanying drawings and with reference to specific embodiments:
[0034] Please refer to Figures 1 to 3 , the embodiment of the present application provides a ladle cover adding and removing device 10. In combination with Figure 1 , the ladle cover adding and removing device 10 includes a frame 100, a lifting pinion 200, and a safety pin 300. Among them, the lifting pinion 200 is liftably provided on the frame 100, the safety pin 300 is vertically movably inserted into the frame 100, the bottom end of the safety pin 300 is correspondingly arranged with the top of the front end of the lifting pinion 200, and the stroke of the safety pin 300 is less than the stroke of the lifting pinion 200.
[0035] Specifically, the frame 100 provides an installation basis for the lifting pinion 200 and the safety pin 300. By installing the lifting pinion 200 and the safety pin 300 on the frame 100, the lifting pinion 200 and the safety pin 300 are arranged on the ladle adding and removing device. The lifting pinion 200 is used to be inserted into the front hinge shaft 21 of the ladle cover 20, and through the lifting movement of the lifting pinion 200, the ladle cover 20 is covered and removed from the ladle. The safety pin 300 is used to block the ladle cover 20 arranged on the lifting pinion 200, so that when the ladle cover 20 falls off the lifting pinion 200, the safety pin 300 blocks the ladle cover 20, thereby reducing the risk of the ladle cover 20 falling off the lifting pinion 200.
[0036] Since the bottom end of the safety pin 300 is correspondingly arranged with the top of the front end of the lifting insert tooth 200, the stroke of the safety pin 300 is smaller than that of the lifting insert tooth 200. Thus, when both the safety pin 300 and the lifting insert tooth 200 are at the lowest point, there is a gap between the bottom end of the safety pin 300 and the top of the front end of the lifting insert tooth 200. At this time, the lifting insert tooth 200 is inserted into the front hinge shaft 21 of the ladle cover 20, avoiding interference between the safety pin 300 and the ladle cover 20. When the lifting insert tooth 200 drives the ladle cover 20 to move upward from the lowest point, the lifting insert tooth 200 moves to a position where it contacts the bottom end of the safety pin 300, and then drives the safety pin 300 to continue moving upward until it reaches the highest point of the lifting insert tooth 200. It should be noted that the highest point of the safety pin 300 refers to the maximum height that the lifting insert tooth 200 can lift the safety pin 300 to, and during this process, the safety pin 300 remains abutted against the lifting insert tooth 200. In this way, the ladle cover 20 is taken off from the ladle, and vice versa, the ladle cover 20 is placed on the ladle.
[0037] When the lifting insert tooth 200 is inserted into the front hinge shaft 21 of the ladle cover 20, the front hinge shaft 21 of the ladle cover 20 is arranged at the position of the anti-falling bevel angle 210 in the middle of the lifting insert tooth 200. The rear end of the lifting insert tooth 200 is connected to the frame 100. The front end of the lifting insert tooth 200 is a suspended end. The lifting insert tooth 200 inserts into the front hinge shaft 21 of the ladle cover 20 along the direction from the front end to the rear end. The direction in which the ladle cover 20 falls off from the lifting insert tooth 200 is from the rear end to the front end of the lifting insert tooth 200. Therefore, when the lifting insert tooth 200 contacts the safety pin 300, the bottom end of the safety pin 300 is kept abutted against the top of the front end of the lifting insert tooth 200. When the ladle cover 20 falls off from the lifting insert tooth 200, the front hinge shaft 21 of the ladle cover 20 moves from the middle of the lifting insert tooth 200 to the front end of the lifting insert tooth 200, and the bottom end of the safety pin 300 that abuts against the top of the front end of the lifting insert tooth 200 blocks the front hinge shaft 21 of the ladle cover 20, thereby reducing the risk of the ladle cover 20 falling off from the lifting insert tooth 200 and improving the safety of the ladle cover adding and taking device 10.
[0038] In some embodiments, such as Figure 1 and Figure 3 shown, the ladle cover adding and taking device 10 further includes a bracket 400. The bracket 400 is arranged on the frame 100, and the safety pin 300 is movably inserted into the bracket 400. Since the front end of the lifting insert tooth 200 extends out of the frame 100, the bracket 400 is connected to the frame 100, so as to arrange the safety pin 300 through the bracket 400, realizing the corresponding arrangement of the bottom end of the safety pin 300 and the top of the front end of the lifting insert tooth 200. The bracket 400 and the frame 100 can be connected by welding, screwing, clamping or other methods, and the embodiments of the present application do not limit this.
[0039] In some embodiments, such as Figure 3 shown, the ladle cover lifting device 10 further includes a sleeve 500. The sleeve 500 is vertically disposed through the bracket 400, and the safety pin 300 is disposed through the bracket 400. An annular protrusion 310 is provided at the top end of the safety pin 300, and the outer diameter of the annular protrusion 310 is greater than the inner diameter of the sleeve 500. Thus, the vertical movement of the safety pin 300 on the bracket 400 is realized through the sleeve 500. At the same time, an annular protrusion 310 is provided at the top end of the safety pin 300, and the outer diameter of the annular protrusion 310 is made greater than the inner diameter of the sleeve 500 to limit the safety pin 300 through the annular protrusion 310, so that the safety pin 300 can be fixed at the lowest point when not in contact with the lifting spline 200.
[0040] In some embodiments, the safety pin 300 and the sleeve 500 are in clearance fit. Through the clearance fit between the safety pin 300 and the sleeve 500, the safety pin 300 moves axially in the sleeve 500.
[0041] In some embodiments, the diameter of the safety pin 300 is 88 mm to 108 mm, the length of the safety pin 300 is 850 mm to 900 mm, and the length of the sleeve 500 is 410 mm to 460 mm. By setting the diameter of the safety pin 300 to be 88 mm to 108 mm, the length of the safety pin 300 to be 850 mm to 900 mm, and the length of the sleeve 500 to be 410 mm to 460 mm, the safety pin 300 has a better blocking effect on the front hinge shaft 21 of the ladle cover 20.
[0042] In some embodiments, such as Figure 3 shown, the bracket 400 is provided with a mounting hole 410, the sleeve 500 is disposed in the mounting hole 410, and flanges 510 are provided at both ends of the sleeve 500. The flanges 510 are connected to the bracket 400. Thus, the setting of the sleeve 500 on the bracket 400 is realized through the mounting hole 410 on the bracket 400, and by blocking the flanges 510 at both ends of the sleeve 500 at both ends of the mounting hole 410 of the bracket 400, the flanges 510 at both ends of the sleeve 500 are fixedly connected to the bracket 400, ensuring the connection stability between the sleeve 500 and the bracket 400. At the same time, fixedly connecting the flanges 510 at both ends of the sleeve 500 to the bracket 400 also plays a role in strengthening the part of the bracket 400 where the safety pin 300 is provided, improving the blocking effect of the safety pin 300 on the front hinge shaft 21 of the ladle cover 20.
[0043] In some embodiments, the flanges 510 at both ends of the sleeve 500 are welded to the bracket 400. By welding, the flanges 510 are fixedly connected to the bracket 400, and usually, in order to ensure the connection effect, full welding is adopted between the flanges 510 and the bracket 400.
[0044] In some embodiments, such asFigure 3 As shown, the bottom end of the safety pin 300 is spherical. When the lifting pin 200 drives the safety pin 300 to move, the bottom end of the safety pin 300 can maintain a better contact effect with the top of the front end of the lifting pin 200.
[0045] In some embodiments, such as Figure 3 As shown, the ladle cover adding and removing device 10 further includes a lifting ring 600, and the lifting ring 600 is arranged at the top end of the safety pin 300. So as to facilitate the placing and removing of the safety pin 300 through the lifting ring 600, and realize the installation and disassembly of the safety pin 300 on the ladle cover adding and removing device 10.
[0046] In some embodiments, such as Figure 3 As shown, the lifting ring 600 is screwed to the safety pin 300. To realize the connection between the lifting ring 600 and the safety pin 300 by screwing. A threaded hole 320 is provided at the connection end of the safety pin 300, and the lifting ring 600 is provided with an external thread, so as to screw the lifting ring 600 into the threaded hole 320 of the safety pin 300, and make the external thread of the lifting ring 600 screwed to the threaded hole 320 of the safety pin 300, realizing the screwing connection between the lifting ring 600 and the safety pin 300.
