[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0030] Embodiment 1
[0031] As Figures 1-6 , the embodiment of the present invention provides a sling seat, including a base box body 1, and the base box body 1 is adapted to be fixed to the electric furnace cover; a hook entrance and exit 10 is provided on the base box body 1, and a hanging point 19 for hanging and cooperating with the hook 2 and a hook guiding channel 17 and a hook removing guiding channel 18 for the hook 2 to pass through are provided in the base box body 1. Among them, the hook guiding channel 17 and the hook removing guiding channel 18 meet at the hook entrance and exit 10 and the hanging point 19 respectively.
[0032] In the above solution, the hook 2 is adapted to enter the base box body 1 from the hook entrance and exit 10, or the hook 2 is taken out from the hook entrance and exit 10. In one of the embodiments, as Figures 1-3 and Figure 6 , the hook entrance and exit 10 is in a funnel shape with a wider upper part and a narrower lower part, which can facilitate the entry and exit of the hook 2 from the hook entrance and exit 10. Especially during the process of the hook 2 entering the base box body 1, it can play a guiding role and reduce the alignment difficulty.
[0033] Preferably, as Figure 2 , Figure 3 and Figure 6 , taking the plane passing through the hook entrance and exit 10 and the hanging point 19 as the reference plane, the hook guiding channel 17 and the hook removing guiding channel 18 are arranged on both sides of the reference plane, which can facilitate the automatic hooking and automatic hook removing operations of the hook 2, and the two operations will not interfere with each other. Among them, optionally, the hanging point 19 is located directly below the hook entrance and exit 10.
[0034] Optionally, as Figure 2 , Figure 3 and Figure 6 , the hanging point 19 is in a U-shaped groove structure with a downward opening, which can facilitate the entry and exit of the hook 2 into and out of the hanging point 19 while meeting the hanging requirements.
[0035] In one of the embodiments, as Figure 6, the hook guiding channel 17 includes a first inclined corridor 171, a first vertical corridor 172, and a first turning corridor 173. The first inclined corridor 171 extends obliquely downward from the hook entrance and exit 10 to communicate with the top end of the first vertical corridor 172. The first turning corridor 173 extends obliquely downward from the bottom end of the first vertical corridor 172 toward the hanging point 19 and communicates with the hanging point 19.
[0036] Preferably, the above-mentioned first vertical corridor 172 is parallel to the vertical plane. The first turning corridor 173 can guide the hook 2 to below the hanging point 19. When the hook 2 is lifted, it can conveniently enter the hanging point 19. Among them, taking the hanging point 19 in the form of a downward-opening U-shaped groove structure as an example, the open end of the hanging point 19 is partially located directly above the first turning corridor 173, which can ensure that the hook 2 can accurately enter the hanging point 19.
[0037] In one embodiment, as Figure 6 , the unhooking guiding channel 18 includes a second inclined corridor 181, a second vertical corridor 182, and a second turning corridor 183. The second inclined corridor 181 extends obliquely downward from the hook entrance and exit 10 to communicate with the top end of the second vertical corridor 182. The second turning corridor 183 extends obliquely upward from the bottom end of the second vertical corridor 182 toward the hanging point 19 and communicates with the hanging point 19.
[0038] Preferably, the above-mentioned second vertical corridor 182 is parallel to the vertical plane. The second turning corridor 183 can guide the hook 2 to the second vertical corridor 182, facilitating the hook 2 to be disengaged from the base box body 1. Among them, taking the hanging point 19 in the form of a downward-opening U-shaped groove structure as an example, the open end of the hanging point 19 is partially located directly above the second turning corridor 183, which can ensure that the hook 2 can accurately enter the unhooking guiding channel 18.
[0039] When the above-mentioned hook guiding channel 17 and unhooking guiding channel 18 are adopted, while ensuring reliable guiding of the hook 2, the two channels can be organically integrated into the base box body 1 and share a hook entrance and exit 10, thereby effectively reducing the volume of the base box body 1 and making it more convenient to use in an electric furnace.
[0040] In one embodiment, as Figures 1-6 , a first one-way structure 15 is provided at the intersection of the hook entrance and exit. The first one-way structure 15 is configured to: allow the hook 2 to enter the hook guiding channel 17 from the hook entrance and exit 10 and allow the hook 2 to enter the hook entrance and exit 10 from the unhooking guiding channel 18, and prevent the hook 2 from entering the unhooking guiding channel 18 from the hook entrance and exit 10.
[0041] In this application, a first one-way structure 15 is provided at the intersection of the hook inlet and outlet. The first one-way structure 15 allows the hook 2 to enter the hook guiding channel 17 from the hook inlet and outlet 10 and allows the hook 2 to enter the hook inlet and outlet 10 from the unhooking guiding channel 18, and prevents the hook 2 from entering the unhooking guiding channel 18 from the hook inlet and outlet 10, which can ensure the reliability and safety of automatic hooking and unhooking.
[0042] In one embodiment, as Figures 1-4 , the first one-way structure 15 includes a first one-way guide plate 151 and a first reset unit. The first one-way guide plate 151 is movably arranged at the intersection of the hook inlet and outlet and is limited to be pushed to a first avoidance position only by the hook 2 output from the unhooking guiding channel 18. The first reset unit is used to reset the first one-way guide plate 151 in the avoidance position.
[0043] Preferably, the first one-way guide plate 151 is rotatably arranged on the base box body 1, and the rotating shaft is parallel to the axial direction of the hook 2. A first limiting part can be arranged on the base box body 1. Under the constraint of the first limiting part, the first one-way guide plate 151 is horizontally arranged at the outlet of the unhooking guiding channel 18 and can prevent the first one-way guide plate 151 from further rotating towards the unhooking guiding channel 18. In this way, the unhooking guiding channel 18 can be closed by the first one-way guide plate 151 to prevent the hook 2 from entering the unhooking guiding channel 18 during hooking. At the same time, during unhooking, under the push of the hook 2, the first one-way guide plate 151 rotates towards the hook guiding channel 17, and the hook 2 can enter the hook inlet and outlet 10 from the unhooking guiding channel 18. Further, a second limiting part can be arranged on the base box body 1, or the rotation stroke of the first one-way guide plate 151 can be restricted by the constraint of the first reset unit. For example, the first one-way guide plate 151 can be limited at the inlet of the hook guiding channel 17 to close the hook guiding channel 17 and prevent the hook 2 from entering the hook guiding channel 17 from the unhooking guiding channel 18.
[0044] The above-mentioned first reset unit includes but is not limited to using a counterweight 152.
[0045] In one embodiment, a second one-way structure 16 is provided at the intersection of the hanging points. The second one-way structure 16 is configured to: allow the hook 2 to enter the unhooking guiding channel 18 from the hook guiding channel 17 and prevent the hook 2 from entering the hook guiding channel 17 from the unhooking guiding channel 18.
[0046] In this application, a second one-way structure 16 is provided at the intersection of the hanging points. The second one-way structure 16 allows the hook 2 to enter the unhooking guiding channel 18 from the hook guiding channel 17 and prevents the hook 2 from entering the hook guiding channel 17 from the unhooking guiding channel 18, which can ensure the reliability and safety of automatic hooking and unhooking.
[0047] In one embodiment, as Figures 2-6 , the second one-way structure 16 includes a second one-way guide plate 161. The second one-way guide plate 161 is movably arranged at the intersection of the hanging points and is defined to be only pushed to the second avoidance position by the lifting hook 2 output from the hook guiding channel 17 and can automatically reset.
[0048] Among them, preferably, the second one-way guide plate 161 is rotatably arranged on the base box body 1, and the rotating shaft is parallel to the axial direction of the lifting hook 2; a third limiting part can be arranged on the base box body 1. Under the constraint of this third limiting part, the second one-way guide plate 161 is horizontally arranged at the entrance of the hook unloading guiding channel 18 and can prevent the second one-way guide plate 161 from further rotating towards the hook guiding channel 17 side. In this way, it can prevent the lifting hook 2 from entering the hook guiding channel 17 from the hook unloading guiding channel 18. At the same time, when unloading the hook, under the push of the lifting hook 2, the second one-way guide plate 161 rotates towards the hook unloading guiding channel 18 side, and the lifting hook 2 can enter the hook unloading guiding channel 18 from the hanging point 19.
[0049] The above-mentioned second one-way guide plate 161 is preferably suspended and installed on the base box body 1, so that it can automatically reset by its own weight.
[0050] In one embodiment, as Figures 1-3 , the base box body 1 includes two base plates 11. Hook guiding grooves 170 and hook unloading guiding grooves 180 are formed on both base plates 11. The two base plates 11 are arranged in parallel and relatively spaced apart and are connected into a box body structure through a connecting structure. The hook guiding grooves 170 of the two communicate to form the hook guiding channel 17, and the hook unloading guiding grooves 180 of the two communicate to form the hook unloading guiding channel 18. The base box body 1 adopting this structure is not only simple in structure but also convenient for maintenance.
[0051] Among them, the two base plates 11 are arranged in parallel and relatively spaced apart, which can facilitate the suspension rod 22 to freely move the hanging part in the base box body 1, improve the smoothness and reliability of the hook hanging and unloading operations. The distance between the two base plates 11 allows the above-mentioned suspension rod 22 to move, and the hanging part moves in the hook guiding channel 17 and the hook unloading guiding channel 18. Therefore, when the hook guiding channel 17 / hook unloading guiding channel 18 is in guiding cooperation with the hanging part, the stability of the hook hanging and unloading operations can be improved. For example, the above-mentioned hanging part adopts a guide wheel 21, and the guide wheel 21 is in guiding cooperation with the above-mentioned hook guiding channel 17 / hook unloading guiding channel 18. For example, the width of the guiding channel matches the diameter of the guide wheel 21 (preferably with a clearance fit), so that the guide wheel 21 can roll smoothly in the guiding channel without jamming.
[0052] Optionally, as Figures 1-3, the above connection structure includes an upper connection beam 12, and both ends of the upper connection beam 12 are fixedly connected to two base plates 11 respectively, and are further preferably detachably fixedly connected; the upper connection beam 12 is preferably connected to the top of the base plate 11. The above connection structure may further include side sealing plates 13 and a lower bottom plate 14, the side sealing plates 13 are respectively fixedly connected to the two base plates 11, and the lower bottom plate 14 is respectively fixedly connected to the two base plates 11; while connecting the two base plates 11, the side sealing plates 13 and the lower bottom plate 14 can enclose the spacing space between the two base plates 11 in the circumferential direction to prevent the hook 2 from disengaging from the side and bottom of the base box body 1.
[0053] Embodiment 2

[0057] The cooperation relationship between the guide wheel 21 and the hook guiding channel 17 / unhooking guiding channel 18 has been described in the above Embodiment 1, and will not be elaborated here.
[0058] Furthermore, as Figure 6 and Figure 7 , the support includes a mounting plate for connecting with the lifting member 3 and a suspension rod 22 hinged to the bottom of the mounting plate, the guide wheel 21 is rotatably connected to the bottom end of the suspension rod 22, and the hinge axis between the suspension rod 22 and the mounting plate is axially parallel to the axis of the guide wheel 21.
[0059] Among them, the spreader seat is preferably adopted the scheme in which the two base plates 11 are arranged in parallel and spaced relatively, so as to facilitate the movement of the suspension rod 22. Preferably, there are two guide wheels 21, and the two guide wheels 21 can move in two hook guiding grooves 170 / two unhooking guiding grooves 180 respectively, which can improve the smoothness and stability of the movement of the hook 2, and the reliability and safety of hanging are also higher.
[0060] The lifting member 3 can be a chain or a steel wire rope, etc. During actual production, the lifting member 3 can maintain a connection relationship with the hook 2, and the lifting member 3 does not need to maintain a connection relationship with the electric furnace cover. Only through the hooking and unhooking operations between the hook 2 and the spreader seat can the electric furnace cover be lifted off and lowered, the operation is convenient and reliable, the labor intensity of personnel is reduced, and the online maintenance work efficiency is improved.
[0061] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
