[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0024] Reference Figures 1-5The utility model provides an embodiment: a kind of steel converter feeding hopper structure, the both sides wall middle position of hopper body 1 is fixedly connected with hanging lug connection side wall 2, the center of hanging lug connection side wall 2 is fixedly connected with movable hanging lug assembly 3, movable hanging lug assembly 3 includes hanging lug matrix 31, the middle position of hanging lug matrix 31 is threadedly connected with driving total bolt 32, the one end fixedly connected with driving disc 38 of driving total bolt 32 is arranged in the inside of hanging lug matrix 31, the outer side wall of hanging lug matrix 31 is fixedly connected with fixed chuck 34 with the end away from hopper body 1, the outer side wall of hanging lug matrix 31 is fixedly connected with movable chuck 35 with the end close to hopper body 1, the surface of driving disc 38 and movable chuck 35 mutually adheres.The hopper is fixed with hook of hopper through movable hanging lug assembly 3, when installing hook, first, hook is hung between fixed chuck 34 and movable chuck 35, subsequently rotates driving total bolt 32, so that driving total bolt 32 drives driving disc 38 to slide to outside, and then movable chuck 35 is moved to the direction of hook, and hook is fixed between fixed chuck 34 and movable chuck 35 by movable chuck 35, compared with traditional rigidity, fixed hook using the sliding characteristic of movable chuck 35, avoid the rigidity damage of hook, also facilitate subsequent disassembly of hook.
[0025] The inner wall of fixed chuck 34 is rotatably connected with second turntable 311, and the inner wall of movable chuck 35 is rotatably connected with first turntable 310.When hook is arranged between movable chuck 35 and fixed chuck 34, first turntable 310 and second turntable 311 adhere to the surface of hook, so that fixed chuck 34 and movable chuck 35 can not only clamp hook in, but also first turntable 310 and second turntable 311 provide good rotation basis for the rotation of hook when clamping hook, which avoids that hook or movable hanging lug assembly 3 is worn when hook and movable hanging lug assembly 3 relatively rotate, and the inner wall of hanging lug matrix 31 is fixedly connected with a plurality of lever seats 36, and the inside of each lever seat 36 is rotatably connected with locking lever 37.By abutting locking lever 37 on the back side of driving disc 38, the problem that hook is loosened due to the sliding of driving total bolt 32 can be avoided.
[0026] A plurality of sub-driving bolts 33 in a circumferential array are threadedly connected to the lug base 31 and located outside the driving total bolt 32. The number of the sub-driving bolts 33 matches that of the locking levers 37, and the locking levers 37 are arranged inside the lug base 31 and abut against the locking levers 37 at one end. By turning the sub-driving bolts 33, the locking levers 37 are driven to rotate, and then the inner ends of the locking levers 37 press against the rear sidewall of the driving disc 38, so that the driving disc 38 cannot slide to the rear side, thereby limiting the driving total bolt 32. This effectively avoids the problem of the hook loosening due to loosening of the threaded structure. A plurality of sliding grooves 39 are formed in the driving disc 38, and the plurality of sub-driving bolts 33 are inserted into the sliding grooves 39. When the driving total bolt 32 drives the driving disc 38 to rotate forward, the sub-driving bolts 33 can slide in the sliding grooves 39 to avoid movement interference.
[0027] The rear sidewall of the hopper body 1 is fixedly connected with a lug tail rod 4. The lug tail rod 4 is connected with the lifting structure, and then drives the lug tail rod 4 to complete the turnover and discharging
[0028] Working principle: The hopper is fixed with the hook through the movable lug assembly 3. When installing the hook, the hook is hooked between the fixed chuck 34 and the movable chuck 35, and then the driving total bolt 32 is turned to drive the driving disc 38 to slide outward, thereby driving the movable chuck 35 to move towards the hook. The hook is fixed between the movable chuck 35 and the fixed chuck 34. Compared with the traditional rigid fixation, the hook is fixed by the sliding property of the movable chuck 35, which avoids the rigid damage of the hook and facilitates the subsequent disassembly of the hook. At the same time, when the hook is arranged between the movable chuck 35 and the fixed chuck 34, the first rotating disc 310 and the second rotating disc 311 are attached to the surface of the hook, so that the fixed chuck 34 and the movable chuck 35 can not only clamp the hook inwardly, but also provide a good rotating basis for the rotation of the hook. This avoids the wear of the hook or the movable lug assembly 3 when the hook rotates relative to the movable lug assembly 3. By turning the sub-driving bolts 33, the locking levers 37 are driven to rotate, and then the inner ends of the locking levers 37 press against the rear sidewall of the driving disc 38, so that the driving disc 38 cannot slide to the rear side, thereby limiting the driving total bolt 32. This effectively avoids the problem of the hook loosening due to loosening of the threaded structure.
[0029] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, the made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
