Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically a hydraulic device for pressing and releasing electrodes with a locking structure. Background Technology

[0002] Hydraulic devices for electrode pressing and releasing are a critical technology in industrial applications, especially in heavy industrial equipment such as submerged arc furnaces and large electric furnaces. Submerged arc furnace electrode pressing and releasing devices also employ an upper and lower brake structure. These brakes, through the coordinated operation of brake cylinders, pressing and releasing cylinders, springs, and wire ropes, complete the electrode pressing and releasing action. This mechanical synchronization ensures the normal pressing and releasing of large-diameter electrodes, improving production efficiency and equipment reliability.

[0003] In current hydraulic devices for pressing and releasing electrodes with locking structures, the application of locking structures is crucial. During operation, the electrode needs to be raised and lowered, but locking the electrode with bolts may not be accurate enough, resulting in unstable electrode position and possible loosening or movement. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulic device for pressing and discharging electrodes with a locking structure, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic device for pressing and releasing electrodes with a locking structure, comprising a hydraulic mechanism for pressing and releasing electrodes and a locking assembly for pressing and releasing electrodes. The hydraulic mechanism for pressing and releasing electrodes includes a pressing and releasing electrode housing. The upper end of the pressing and releasing electrode housing is connected and fixed to a telescopic hydraulic cylinder by bolts. A telescopic guide post is fixedly installed at the lower end of the telescopic hydraulic cylinder. A fixing frame is installed at the lower end of the telescopic guide post. A first fixing locking plate and a second fixing locking plate are installed at one end of the fixing frame. Sliding grooves are formed inside the first fixing locking plate and the second fixing locking plate.

[0006] As a further preferred embodiment of this technical solution, a sliding block is slidably connected inside the sliding groove, and a first L-shaped locking block and a second L-shaped locking block are fixedly installed at one end of the sliding block.

[0013] Beneficial effects:

[0014] (1) This utility model uses the contraction force of the telescopic spring to tightly clamp the first L-shaped clamp and the second L-shaped clamp onto the electrode plate.

Detailed Implementation

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1 , Figure 3 , Figure 4 As shown, in this embodiment, a hydraulic device for pressing and releasing electrodes with a locking structure includes a hydraulic mechanism 100 for pressing and releasing electrodes and a locking assembly for pressing and releasing electrodes. The hydraulic mechanism 100 for pressing and releasing electrodes includes an electrode housing 101. The upper end of the electrode housing 101 is connected and fixed to a telescopic hydraulic cylinder 201 by bolts. A telescopic guide post 202 is fixedly installed at the lower end of the telescopic hydraulic cylinder 201. A fixing frame 203 is installed at the lower end of the telescopic guide post 202. A first fixing locking plate 205 and a second fixing locking plate 206 are installed at one end of the fixing frame 203. A sliding groove 210 is provided inside the first fixing locking plate 205 and the second fixing locking plate 206. A sliding block 213 is slidably connected inside the sliding groove 210. A first L-shaped locking block 214 and a second L-shaped locking block 215 are fixedly installed at one end of the sliding block 213.

[0024] like Figure 3-5 As shown, a telescopic spring 212 is installed at one end of the sliding block 213. One end of the telescopic spring 212 is installed inside the first fixed locking plate 205 and the second fixed locking plate 206. A fixing bolt 211 is connected through the first fixed locking plate 205 and the second fixed locking plate 206. The fixing bolt 211 is rotatably connected inside the sliding block 213. The first L-shaped locking block 214 and the second L-shaped locking block 215 are slidably connected inside the two sides of the electrode plate 207. L-shaped slots 216 are opened inside the two sides of the electrode plate 207.

[0025] By fixing the L-shaped locking blocks of the first fixing locking plate 205 and the second fixing locking plate 206 inside the electrode plate 207, and by moving the first L-shaped locking block 214 and the second L-shaped locking block 215 in both vertical directions, and extending the telescopic spring 212, the first L-shaped locking block 214 and the second L-shaped locking block 215 are further slidably engaged and connected inside the slot of the electrode plate 207. Then, the contraction force of the telescopic spring 212 tightly clamps the first L-shaped locking block 214 and the second L-shaped locking block 215 against the electrode plate 207. The operator tightens the fixing bolt 211 inside the fixing locking plate and the L-shaped locking block to further ensure that the L-shaped locking block can stably fix the electrode plate 207. This avoids the instability of electrode position caused by using bolts to lock the electrode, and prevents loosening or movement. By avoiding the use of traditional bolt fixing methods, the problem of electrode position instability caused by loosening or movement of bolts can be reduced, and the electrode plate 207 can be effectively and conveniently disassembled, installed, replaced or repaired. Then, by driving the telescopic hydraulic cylinder 201, the telescopic guide column 202 is moved up and down, which in turn drives the electrode plate 207 to move up and down.

[0026] like Figure 1-3 As shown, a first moving block 208 and a second moving block 209 are fixedly installed at both ends of the electrode plate 207. The first moving block 208 and the second moving block 209 are slidably connected to the inside of both sides of the pressing electrode box 101. Moving track grooves 103 are opened inside both sides of the pressing electrode box 101. A base plate 102 is installed at the lower end of the pressing electrode box 101.

[0027] This utility model provides a hydraulic device for pressing and releasing electrodes with a locking structure. The specific working principle is as follows: The L-shaped locking blocks of the first fixing locking plate 205 and the second fixing locking plate 206 are fixed inside the electrode plate 207. By moving the first L-shaped locking block 214 and the second L-shaped locking block 215 in both vertical directions, and extending the telescopic spring 212, the first L-shaped locking block 214 and the second L-shaped locking block 215 are slidably engaged and connected inside the slot of the electrode plate 207. Then, the contraction force of the telescopic spring 212 tightly clamps the first L-shaped locking block 214 and the second L-shaped locking block 215 against the electrode plate 207. The operator tightens the fixing bolt 211 inside the fixing locking plate and the L-shaped locking blocks to further ensure... The L-shaped locking block can stably fix the electrode plate 207, avoiding the instability of electrode position caused by using bolts to lock the electrode, and preventing loosening or movement. By avoiding the use of traditional bolt fixing methods, the problem of electrode position instability caused by loosening or movement of bolts can be reduced. It can effectively and conveniently disassemble, install, replace or repair the electrode plate 207. The electrode plate 207 is fixedly installed on one end of the first moving block 208 and the second moving block 209. When the telescopic hydraulic cylinder 201 drives the telescopic guide column 202 to move up and down, it further drives the electrode plate 207 to move up and down, and further drives the first moving block 208 and the second moving block 209 to move. The moving blocks move up and down inside the moving guide groove.
