Description

Technical Field

[0001] The utility model belongs to the technical field of sling equipment, in particular to an electrolytic cell shell breaking hammer rod sling. Background Art

[0002] The shelling hammer rod of the electrolytic cell is a seamless steel pipe that completes the shelling action during the production operation of the electrolytic cell. A 400mm solid hammer head is installed at the front end. The total length of the shelling hammer rod is 1900mm, and the middle part of the shelling hammer rod is inside the guide tube. During normal use, the shelling hammer rod is driven by the cylinder to reciprocate up and down in the guide tube. Once the weld of the shelling hammer rod breaks during use, it will fall into the guide tube 300mm away from the upper mouth. The top of the shelling hammer rod is a hollow structure with no available lifting points. The bottom of the shelling hammer rod is the cathode part of the electrolytic cell. There is not enough space to remove the hammer rod from the bottom as a whole. The upper part of the shelling hammer rod is in the guide tube, and it is impossible to install an ordinary hoist to lift it out. There is a lack of a hoist to lift the shelling hammer rod from the upper part of the guide tube. Utility Model Content

[0009] The outer diameter of the lock nut is smaller than the outer diameter of the plane bearing.

[0010] The beneficial effect of the utility model is that when the shell breaking hammer rod is broken, the three grabbing clamps of the shell breaking hammer rod lifting device of the utility model are used to penetrate into the broken hammer rod and lock the locking nut on the top of the lifting ring. At this time, the three grabbing clamps are pushed outwards by the drive of the trapezoidal slider and supported on the inner wall of the hammer rod. With the cooperation of the lifting crown, the lifting ring is lifted and the shell breaking hammer rod can be lifted away from the guide cylinder. The installation is convenient and fast, the operation is simple and the reliability is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0017] Example 1

[0018] The utility model electrolytic cell shell hammer rod hanging device is as follows Figure 1 and Figure 2 As shown, it includes a support sleeve 5, a pull rod 6 is arranged inside the support sleeve 5, the pull rod 6 can slide up and down inside the support sleeve 5, and the top and bottom of the pull rod 6 are extended out of the support sleeve 5, a connecting block 13 is arranged on the top of the pull rod 6, and a lifting ring 11 is arranged on the connecting block 13; Figure 3 As shown, a trapezoidal slider 2 is provided at the bottom of the pull rod 6, and the upper bottom of the trapezoidal slider 2 is threadedly connected to the bottom of the pull rod 6; the upper part of the pull rod 6 is a threaded section and is provided with a locking nut 9; the locking nut 9 is used to limit and lock the pull rod 6 in the support sleeve 5 to allow it to move up and down;

[0019] like Figure 4 As shown, a first pad 7 is arranged on the top of the support sleeve 5, a plane bearing 8 is arranged above the first pad 7, a second pad 14 is arranged above the plane bearing 8, and the second pad 14 is located below the locking nut 9;

[0020] A mounting frame 4 is provided at the bottom of the support sleeve 5, and the mounting frame 4 is located above the trapezoidal slider 2. A through hole is provided in the middle of the mounting frame 4. The mounting frame 4 is hingedly connected to the three gripping clips 3 through a pin shaft 10. A positioning hole is provided at the end of the pin shaft 10, and a cotter pin 1 is installed in the positioning hole; the trapezoidal slider 2 can open the three gripping clips 3 when sliding; when the locking nut 9 is locked, the trapezoidal slider 2 moves upward, and the side of the trapezoidal slider 2 drives the gripping clips 3 to move outward;

[0021] Example 2

[0022] Different from Example 1, the outer diameter of the plane bearing 8 is larger than the outer diameter of the support sleeve 5; the outer diameter of the locking nut 9 is smaller than the outer diameter of the plane bearing 8; since the outer diameter of the support sleeve 5 is smaller than the plane bearing 8, in order to avoid damaging the plane bearing 8, a first pad 7 is installed between the support sleeve 5 and the plane bearing 8; when the locking nut 9 rotates, it relies on the plane bearing 8 to slide, so as to avoid driving the support sleeve 5 to rotate together during the locking process; since the outer diameter of the locking nut 9 is smaller than the plane bearing 8, in order to avoid damaging the plane bearing 8, a second pad 14 is installed between the locking nut 9 and the plane bearing 8.

[0023] Example 3

[0024] The specific working principle of the utility model electrolytic cell shell breaking hammer rod hanger is:

[0025] When in use, put the lower half of the whole sling into the broken shell hammer rod, and reserve 200mm space at the top. When in use, first loosen the locking nut 9, and the three grabbing clips 3 are in a naturally drooping state. At this time, the outer diameter of the three grabbing clips 3 is 60mm, which is much smaller than the inner diameter of the hammer rod 12. At this time, put the lower half of the device into the broken hammer rod, and the lifting ring 11 is reliably connected to the lifting belt of the lifting machinery. Use a wrench to gradually tighten the locking nut 9. At this time, under the support of the support sleeve 5, the trapezoidal slider 2 gradually moves upward. At this time, the lower ends of the three grabbing clips 3 are continuously stretched outward and pressed against the inside of the hammer rod 12. Then command the crane to lift the whole device. At this time, the broken shell hammer rod is lifted together with the sling under the action of friction.
