DETAILED DESCRIPTION

[0026] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, Figure 1 This is a structural front view of the welded slag pot adapted to various tipping conditions; Figure 2 This is a structural side view of the welded slag pot adapted to various tipping conditions; Figure 3 This is a bottom view of the structure of the welded slag pot that is adapted to various tipping conditions.

[0029] The welded slag pot adapted to various tilting working conditions of the present invention comprises a pot body 1, a rotating part 2, a motorized tilting part 3 and a manual tilting part 4, wherein the rotating part 2 comprises two rotating shafts, which are symmetrically arranged on the pot body 1 and coaxially arranged. The pot body 1 can be rotated around the axis on the tilting machine by setting the two rotating shafts on the tilting machine, or the pot body 1 can be lifted and moved horizontally as a whole by hooking two mobile hooks 5 on the two rotating shafts respectively; the motorized tilting part 3 comprises two rotating shafts, which are symmetrically arranged on the pot body 1 and coaxially arranged. The tilting portion 3 is arranged at the bottom of the tank body 1 for connecting with the rotating arm 6 of the tilting machine. The rotating arm 6 of the tilting machine rotates around the axis of the rotating shaft, thereby realizing the motorized tilting operation of the tank body 1 around the axis; the manual tilting portion 4 is detachably connected to the tank body 1, and the manual tilting portion 4 is connected to the tilting driving hook 7. The operator operates the tilting driving hook 7 to pull the manual tilting portion 4 to move the bottom and one side of the tank body 1 upward, thereby realizing manual tilting of the tank body 1 around the axis.

[0030] Specifically, the rotating shaft includes a mounting section 21 and a hooking section 22. Both the mounting section 21 and the hooking section 22 are cylindrical, and the mounting section 21 is fixedly connected to the tank body 1 via the hooking section 22. The mounting section 21 is used to be mounted on the rotating seat 8 of the tilting machine to achieve a fixed position of the tank body 1 on the tilting machine. The hooking section 22 is correspondingly arranged to the mobile driving hook 5 so that the mobile driving hook 5 can be hooked with the hooking section 22. Generally, the cross-sectional diameter of the hooking section 22 is smaller than the cross-sectional diameter of the mounting section 21, thereby facilitating the confinement of the mobile driving hook 5 within the region of the hooking section 22 to prevent unhooking.

[0031] The bottom of the tank body 1 is provided with a bottom panel 11, which is annularly arranged around the bottom of the tank body 1. The bottom panel 11 is provided with a mounting groove, and the motorized tilting part 3 is fixedly arranged in the mounting groove. The motorized tilting part 3 is provided with a connecting groove, and the extending direction of the connecting groove is consistent with the axial direction of the rotating shaft. The rotating arm 6 of the tilting machine is arranged in the connecting groove, thereby ensuring that the rotating arm 6 can drive the tank body 1 to rotate around the rotating shaft. A connecting seat 12 is provided at the center position of the bottom panel 11, and a connecting plate 13 is provided on the outer side of the bottom panel 11. The connecting line between the connecting plate 13 and the connecting seat 12 is perpendicular to the axis of the rotating shaft. The manual tilting part 4 is connected to the connecting plate 13 and the connecting seat 12 at the same time. The manual tilting part 4 is pulled by the tilting hook 7 to drive the connecting plate 13 and the connecting seat 12 to rotate around the rotating shaft, thereby realizing the tilting of the tank body 1 around the axis.

[0032] The utility model provides a detachable manual tilting part 4. When only the tilting machine is needed, the manual tilting part 4 can be removed from the tank body 1 to ensure smooth rotation of the tank body 1 during motorized tilting. When the tilting machine fails and manual tilting is required by moving the driving hook 5, the manual tilting part 4 can be installed on the tank body 1 to realize manual tilting of the tank body 1. Therefore, different tilting methods can be adopted based on actual working conditions, and the utility model has strong applicability.

[0033] Example 2

[0034] like Figure 4 As shown, Figure 4It is a three-dimensional view of the structure of the tank body; the motorized tilting part 3 includes two side plates 31 and a top plate 32, and the two side plates 31 are respectively vertically arranged at the bottom of the top plate 32, thereby forming the connecting groove of the U-shaped structure, and the notch of the connecting groove is downward, so that when the tank body 1 is hung in the tilting machine, the rotating arm 6 of the tilting machine enters the connecting groove through the notch of the connecting groove, thereby realizing the connection between the motorized tilting part 3 and the tilting machine.

[0035] The bottom panel 11 is provided with a notch to form the mounting groove, the two side panels 31 are both provided in the mounting groove, the side panels 31 are fixedly connected to the bottom panel 11 and the tank body 1, the top panel 32 is provided on the outside of the bottom panel 11, the top panel 32 is fixedly connected to the bottom panel 11 and the side panels 31, thereby ensuring the overall structural stability of the connection groove.

[0036] Preferably, the motorized tilting portion 3 also includes a reinforcing plate 33, which is arranged on both sides of the mounting groove. The reinforcing plate 33 is fixedly connected to the bottom panel and the side panel 31. When the rotating arm 6 drives the tank body 1 to rotate, the two side panels 31 are subjected to greater force. The setting of the reinforcing plate 33 can further enhance the stability of the side panels 31 to ensure that the tilting machine drives the motorized tilting portion 3 to perform effective motorized tilting.

[0037] Example 3

[0038] like Figure 5 As shown, Figure 5 It is a structural view of the manual tilting part; the manual tilting part 4 includes a tilting rod 41 and a tilting frame, the tilting frame includes a fixed plate 42, a first connecting shaft 43, a second connecting shaft 44 and a third connecting shaft 45, the two fixed plates 42 are arranged in parallel, and both ends of the first connecting shaft 43, the second connecting shaft 44 and the third connecting shaft 45 are respectively connected to the two fixed plates 42, one end of the tilting rod 41 is rotatably connected to the first connecting shaft 43, and the other end is connected to the connecting seat 12 through the fourth connecting shaft 46, the second connecting shaft 44 is connected to the connecting plate 13, and the third connecting shaft 45 is connected to the tilting driving coupler 7, so that the tilting driving coupler 7 can be fixedly connected to the tank body 1 through the manual tilting part 4.

[0039] Generally, the tilting frame further includes a stabilizing plate 47 , and the stabilizing plate 47 is connected to the two fixing plates 42 at the same time to ensure that the two fixing plates 42 are stable in a vertical state.

[0040] Specifically, the connecting seat 12 includes two parallel seat plates, both ends of the fourth connecting shaft 46 are respectively arranged on the two seat plates, and the end of the tilting rod 41 is arranged between the two seat plates, so that the tilting rod 41 can rotate around the fourth connecting shaft 46.

[0041] The connecting plate 13 is provided with a fixing groove, the notch of the fixing groove faces upward, and the cross section of the fixing groove is set to be J-shaped. The second connecting shaft 44 is set in the fixing groove, thereby realizing the connection between the second connecting shaft 44 and the connecting plate 13.

[0042] When installing the manual tilting part 4, first insert the second connecting shaft 44 into the fixing groove through the notch of the fixing groove to fix the position, and then rotate the tilting rod 41 around the first connecting shaft 43, so that the end of the tilting rod 41 is set in the connecting seat 12, and pass through the fourth connecting shaft 46 to realize the connection between the end of the tilting rod 41 and the connecting seat 12, thereby completing the rapid installation of the manual tilting part 4 on the tank body 1.

[0043] The tilting rod 41 can rotate around the fourth connecting shaft 46 and the first connecting shaft 43. While ensuring convenient installation, the second connecting shaft 44 can be adjusted and moved in the fixed groove when the tilting frame is subjected to force, ensuring that the second connecting shaft 44 contacts and applies force with the connecting plate 13, so that the position of the connecting plate 13 will also be pulled upward by force, dispersing the tension, avoiding damage to the connecting seat 12 or the tilting rod 41 due to excessive force, and at the same time, the tank body 1 is tilted by the tension of the bottom and side surfaces, which can make the tilting more stable.

[0044] Preferably, the tank body 1 is provided with two connecting plates 13, and the two connecting plates 13 are symmetrically arranged on both sides of the connecting seat 12. When tipping over to dump metal slag, long-term unilateral tipping will cause serious wear and tear on the upper port on one side of the tank body 1. By symmetrically arranging the two connecting plates 13 and the setting of the connecting seat 12 structure, the manual tilting part 4 can be set on either side based on actual conditions. When the upper port on one side of the tank body 1 is severely worn and cannot be used anymore, by changing the side of the manual tilting part 4 and using the upper port on the other side of the tank body 1 to dump metal slag, the service life of the tank body 1 can be greatly extended and the production cost can be reduced.

[0045] Example 4

[0046] Whether it is manual or mechanical tipping, the bottom of the tank body 1 is the main force-bearing position, so the first reinforcing rib 14, the second reinforcing rib 15 and the third reinforcing rib 16 are provided in the bottom enclosure 11, the two first reinforcing ribs 14 are arranged in parallel, and the two ends of the first reinforcing rib 14 are fixedly connected to the inner wall of the bottom enclosure 11, and the upper part of the first reinforcing rib 14 is fixedly connected to the tank body 1; the two second reinforcing ribs 15 are arranged between the two first reinforcing ribs 14, and the two ends of the second reinforcing rib 15 are respectively vertically connected to the two first reinforcing ribs 14, and the upper part of the second reinforcing rib 15 is fixedly connected to the tank body 1, and the end of the side panel 31 provided in the bottom enclosure 11 is fixedly connected to the second reinforcing rib 15; the third reinforcing rib 16 is provided on both sides of the connecting seat 12, and the two ends of the third reinforcing rib 16 are respectively vertically connected to the second reinforcing rib 15 and the seat plate, and the upper part of the third reinforcing rib 16 is fixedly connected to the tank body 1.

[0047] Through the structural arrangement of the first reinforcing rib plate 14, the second reinforcing rib plate 15 and the third reinforcing rib plate 16, the connection strength between the manual tilting part 4 and the motorized tilting part 3 and the tank body 1 is strengthened to ensure the overall stability during tilting.

[0048] The bottom panel 11 and the first reinforcing rib plate 14 are both provided with an avoidance groove 17 , and the tilting rod 41 is arranged in the avoidance groove 17 to prevent the tilting rod 41 from interfering with the bottom panel 11 and the first reinforcing rib plate 14 and affecting the normal setting of the manual tilting part 4 .

[0049] Example 5

[0050] The use method of the welded slag pot adapted to various tipping working conditions of the utility model includes a first working condition, a second working condition and a third working condition.
