[0030] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.
[0031] like Figure 1-8 As shown, the electrode hoisting extension clamp includes a crossbeam 1; it also includes: a hoisting shackle 3, on both sides of which a lifting rod 2 is connected, and the top of the lifting rod 2 is connected to both sides of the crossbeam 1; a lifting ring 5, on the bottom of which a stud 6 is fixedly installed, and a nut seat 101 is provided in the middle of the crossbeam 1, and the nut seat 101 is threadedly connected to the stud 6; a lubrication mechanism 9 is provided on one side of the stud 6; and a locking shackle 7, on which multiple grips 8 are fixedly installed around its perimeter.
[0032] In practice, the electrode 10 to be used is clamped and fixed by the lifting shackle 3, while the locking shackle 7 is clamped and fixed at the bottom of the electrode 10. The external lifting equipment clamps the lifting ring 5 and moves the electrode 10 by lifting, so that the lifting electrode 10 is aligned with the top of the electrode 10 in use. Then, the operator pushes the handle 8 to make the locking shackle 7, the electrode 10, the lifting shackle 3, the lifting rod 2 and the crossbeam 1 rotate together, and the electrode 10 is threaded. At the same time, the nut seat 101 on the crossbeam 1 is screwed with the stud 6, so that the electrode 10 is threaded and automatically lowered while the electrode 10 is threaded, avoiding the need for lowering by external lifting equipment.
[0033] like Figure 3As shown, the lifting shackle 3 includes a first arc-shaped clamping plate 301 and a second arc-shaped clamping plate 302. The first arc-shaped clamping plate 301 and the second arc-shaped clamping plate 302 are rotatably connected by a first rotating shaft 303. A locking mechanism is provided at the end of the first arc-shaped clamping plate 301 and the second arc-shaped clamping plate 302 away from the first rotating shaft 303. The locking mechanism includes a first U-shaped seat 304 and a second U-shaped seat 305. The first U-shaped seat 304 is fixedly installed at the end of the first arc-shaped clamping plate 301 away from the first rotating shaft 303, and the second U-shaped seat 305 is fixedly installed at the end of the second arc-shaped clamping plate 302 away from the first rotating shaft 303. A second rotating shaft 306 is rotatably installed inside the first U-shaped seat 304. A first screw 307 is fixedly installed on the second rotating shaft 306. A first clamping nut 308 is threaded onto the first screw 307. The first clamping nut 308 is pressed against one side of the second U-shaped seat 305. A handle 309 is fixedly installed at the end of the first screw 307 away from the second rotating shaft 306, and the handle 309 is provided with a number of anti-slip textures around its perimeter.
[0034] The lifting shackle 3 is used to secure the electrode 10. Its specific use is as follows: with the first clamping nut 308 loosened, the lifting shackle 3 is placed on the electrode 10. Tightening the first clamping nut 308 clamps the electrode 10 using the first arc-shaped clamping plate 301 and the second arc-shaped clamping plate 302. When the lifting shackle 3 separates from the electrode 10, loosening the first clamping nut 308 releases the electrode 10 using the first arc-shaped clamping plate 301 and the second arc-shaped clamping plate 302.
[0035] like Figure 2 As shown, the hoisting shackle 3 is provided with a number of limiting hooks 4 arranged in a circular array around its perimeter. The bottom end of the limiting hook 4 is fixed to the first arc-shaped clamping plate 301 and the second arc-shaped clamping plate 302, and the top end of the limiting hook 4 is provided with a bent part.
[0036] When electrode 10 is fitted into lifting shackle 3, the bent part of limit hook 4 contacts the top of electrode 10 to prevent it from being positioned.
[0037] like Figure 4As shown, the locking ring 7 includes a third arc-shaped clamping plate 701 and a fourth arc-shaped clamping plate 702; the third arc-shaped clamping plate 701 and the fourth arc-shaped clamping plate 702 are rotatably connected by a third rotating shaft 703. A first seat 704 is fixedly installed at the end of the third arc-shaped clamping plate 701 away from the third rotating shaft 703, and a second seat 705 is fixedly installed at the end of the fourth arc-shaped clamping plate 702 away from the third rotating shaft 703. A second screw 706 is provided between the first seat 704 and the second seat 705. One end of the second screw 706 is rotatably installed into the first seat 704, and a second clamping nut 707 is threaded onto the second screw 706, pressing the second clamping nut 707 onto the second seat 705.
[0038] The locking ring 7 is used to clamp and fix the bottom of the electrode 10. When the electrodes 10 are extended, the handle 8 on it provides the operator with a position to push and rotate.
[0039] The second clamping nut 707 on the second screw 706 is loosened, the second screw 706 is flipped, and the second screw 706 is separated from the second seat 705. Then, the third arc-shaped clamping plate 701 and the fourth arc-shaped clamping plate 702 are opened by the third rotating shaft 703, and the bottom end of the electrode 10 is surrounded by the third arc-shaped clamping plate 701 and the fourth arc-shaped clamping plate 702. Then, the second screw 706 is flipped, so that the second screw 706 enters the second seat 705, and the second clamping nut 707 is tightened, so that the locking ring 7 is installed at the bottom end of the electrode 10.
[0040] like Figure 5 and Figure 8 As shown, a base 201 is fixedly installed at the bottom end of the lifting rod 2, and a groove is provided in the base 201. Placement rods 310 are fixedly installed on both sides of the lifting ring 3, and the placement rods 310 are fitted into the groove.
[0041] The above provides an embodiment for connecting the lifting rod 2 and the lifting shackle 3; the installation is achieved by suspending the rod 310 in the mounting base 201.
[0042] like Figure 5-7As shown, the lubrication mechanism 9 includes an oil tank 901; the oil tank 901 is fixedly installed to the bottom of the crossbeam 1, a pump body 902 is provided inside the oil tank 901, the pump body 902 is connected to an oil delivery pipe 903, and the oil delivery pipe 903 extends to one side outside the oil tank 901, a sleeve 904 is sleeved on one side of the oil delivery pipe 903, the end of the sleeve 904 is fixedly connected to a hollow shell 905, a brush bristle 906 is provided on one side of the hollow shell 905, and a plurality of evenly distributed fine holes 907 are opened on the side of the hollow shell 905 where the brush bristle 906 is provided, and one side of the brush bristle 906 abuts against one side of the stud 6. A piston sleeve 909 is fixedly sleeved at one end of the oil pipe 903 located inside the casing 904, and the piston sleeve 909 is connected to the inner wall of the casing 904. A spring 908 is provided inside the casing 904, and the inner wall of the end of the casing 904 is elastically connected to the end of the oil pipe 903 through the spring 908.
[0043] During overall use, the lubrication mechanism 9 provides lubrication for the stud 6. Specifically, the pump body 902 draws lubricating oil from the oil tank 901 and delivers it into the hollow shell 905 through the oil pipe 903 and the sleeve 904. Then, the oil enters the bristles 906 through the fine hole 907, so that the bristles 906 are covered with oil. At the same time, the spring 908 is in a compressed state, so that the bristles 906 abut against the stud 6.
[0044] When the nut seat 101 and the stud 6 are screwed together, the lubrication mechanism 9 moves together with the nut seat 101 and applies oil to the surface of the stud 6 through the brush bristles 906 to achieve lubrication. Through lubrication, the wear between the nut seat 101 and the stud 6 is reduced.
[0045] As one embodiment, the locking ring 7 has two parallel top cups 708 on both its front and rear sides. After the electrode 10 is threaded, as... Figure 9 As shown, a locking ring 7 is also installed on the top of the lower electrode 10, and a pressure device is used to pressurize it to tighten the two electrodes 10, improve the threaded connection effect, and prevent the problem of poor tightening effect caused by manual tightening.
[0046] The pressure testing device specifically employs an electric pump 12 and two hydraulic cylinders 11, with the electric pump 12 connected to the two hydraulic cylinders 11, as follows: Figure 9 As shown, the hydraulic cylinder 11 is placed at the top cup 708 of the two locking rings 7. The hydraulic cylinder 11 is pressurized by the electric pump 12, and the hydraulic cylinder 11 extends. The upward force of the extended hydraulic cylinder 11 causes the two electrodes 10 to rotate relative to each other to achieve tightening. After the specified pressure is reached, the pressurization stops, and the electric pump 12 causes the hydraulic cylinder 11 to retract, completing the connection.
