11-12, The side wall of the exhaust tube 2 is fixedly provided with a rotary connecting seat 22 and an installation seat 23, the rotary connecting seat 22 is rotationally connected to the base main body 1 through a hinge shaft 221, the second housing 4 is fixedly arranged at the end part of the exhaust tube 2, the installation seat 23 is rotationally connected with a swinging frame 24 through a first pin shaft 231, the first housing 3 is fixedly connected to the swinging frame 24, the base main body 1 is rotationally connected with a pull rod assembly 15 through a rotating shaft 14, one end of the pull rod assembly 15, which is far away from the rotating shaft 14, is rotationally connected to the swinging frame 24 through a second pin shaft 150, and the rotating shaft 14, the hinge shaft 221, the first pin shaft 231, the second pin shaft 150, the exhaust tube 2, the pull rod assembly 15 and the swinging frame 24 jointly form a parallelogram link mechanism; when the driving device drives the exhaust tube 2 to drive the pull rod assembly 15 to tilt relative to the base body 1, the parallelogram linkage mechanism drives the second housing 4 to switch between an open state and a split state relative to the first housing 3, when a cathode needs to be pulled out of the electrolytic furnace, the driving device drives the exhaust tube 2 to tilt upwards relative to the base body 1 and lift, the exhaust tube 2 drives the pull rod assembly 15 to lift upwards and drives the first housing 3 and the second housing 4 to lift upwards, in the process of lifting the first housing 3 and the second housing 4 upwards, as the second housing 4 is fixedly connected to the end part of the exhaust tube 2, under the linkage action of the parallelogram linkage mechanism, the pull rod assembly 15 pulls the swing frame 24 to rotate along the first pin 231 through the second pin 150, so that the first housing 3 is driven to tilt downwards by taking the first pin 231 as a rotation center, the split state of the first housing 3 and the second housing 4 is driven to tilt upwards to open state, the cathode is effectively avoided, the cathode is conveniently taken out of the electrolytic furnace.
As shown in fig. 11-16, the pull rod assembly 15 includes a sleeve 151 and a support rod 152, one end of the sleeve 151 is fixedly connected with the end of the support rod 152, the other end of the sleeve 151 is rotatably connected to the base body 1 through a rotating shaft 14, one end of the support rod 152 away from the sleeve 151 is rotatably connected to the swinging frame 24 through a second pin shaft 150, a waist-shaped hole 1510 is formed in the sidewall of the sleeve 151, a threaded hole 1520 is formed in the sidewall of the support rod 152, the bolt 153 is in threaded connection with the threaded hole 1520 through the waist-shaped hole 1510, when the driving device drives the exhaust pipe 2 to tilt, the exhaust pipe 2 drives the support rod 152 and the sleeve 151 to lift synchronously through the swinging frame 24, under the linkage of the parallelogram linkage, the sleeve 151 and the support rod 152 simultaneously give a reverse pulling force to the swinging frame 24, so that the swinging frame 24 tilts downwards along the first pin shaft 231 relative to the exhaust pipe 2, and the purpose that the first housing 3 tilts downwards relative to the second housing 4 is achieved, in addition, the relative position of the waist-shaped hole 1510 in the adjusting bolt 153 can be realized, the length of the support rod 152 extending out of the sleeve 151 is adjusted, the driving device is set as an electric cylinder 103, the sidewall of the exhaust pipe 2 is provided with a mounting part 20, and the mounting part 20 is arranged on the sidewall of the exhaust pipe 2, and the mounting part 20 is located close to the side of the second housing 4 and the hinge part 20 is arranged on the side of the hinge part 2, and the hinge part is close to the hinge part 20 when the hinge part is arranged.
As shown in fig. 11-15, the mounting seat 23 and the exhaust tube 2, the rotary connecting seat 22 and the exhaust tube 2 are fixedly connected through a plurality of clamps 25, so that the exhaust tube 2 and the pull rod assembly 15 are detachably connected, subsequent cleaning or replacement of parts is facilitated, the base main body 1 is provided with an avoidance groove 19 corresponding to the pull rod assembly 15, the end face of the exhaust tube 2, which is far away from the second housing 4, is provided with a sealing ring 26, and when the driving device drives the exhaust tube 2 to reset to a use state, one end of the exhaust tube 2, which is far away from the second housing 4, can be tightly attached to the end face of the corresponding connecting tube 6 through the sealing ring 26, so that the connection tightness of the tail end of the exhaust tube 2 is improved.
The foregoing description is only of the preferred embodiments of the invention, and all changes and modifications that come within the meaning and range of equivalency of the structures, features and principles of the invention are therefore intended to be embraced therein.
