The utility model can solve the problems in the prior art that the cost of automatically clamping and releasing materials by driving the clamping jaws by hydraulic devices is high and the laying of hydraulic pipelines is relatively complicated.

[0038] Among them, a first pull ring 112 is rotatably installed on one end of the rotating shaft 109 located outside the first rotating plate 107, and the first pull ring 112 is connected to a second driving device. When hoisting the electrode rod, the second driving device connected to the first pull ring 112 cooperates with the first driving device connected to the rotating plate assembly 102 to move the driving clamp to a position corresponding to the electrode rod; the first rotating plate 107 and the second rotating plate 108, which are rotatably connected, move downward together with the first pull ring 112 to contact the electrode rod under the action of the second driving device. At this time, the first driving device connected to the first rotating plate 107 and the second rotating plate 108 drives the first rotating plate 107 and the second rotating plate 108 to rotate downward away from the rotating shaft 109. After the clamping jaws 101 connected to the first rotating plate 107 and the second rotating plate 108 are in an open state, a clamping member is formed between the two clamping jaws 101. holding area; after the electrode rod enters the clamping area, it contacts the buffer assembly 103, and the buffer assembly 103 positions and buffers the electrode rod; the first driving device drives the first rotating plate 107 and the second rotating plate 108 to rotate upward at one end away from the rotating shaft 109, and at this time, the clamping jaws 101 connected to the first rotating plate 107 and the second rotating plate 108 rotate toward the direction of the rotating shaft 109, and the clamping jaws 101 are tightened to clamp the electrode rod; after the clamping jaws 101 complete the clamping of the electrode rod, the second driving device connected to the first pull ring 112 lifts the electrode rod and then transfers it, so that while realizing the automatic clamping of the pipeline, the process of the clamping jaws 101 clamping the electrode rod is more convenient.

The connection block is provided with a second mounting groove. The second pressure plate 119 and the second mounting groove are connected via a second spring. After the first driving device drives the first rotating plate 107 and the second rotating plate 108 in the two rotating plate assemblies 102 to rotate upward around the rotating shaft 109 to clamp the electrode rod, the second pressure plate 119 contacts the surface of the electrode rod under the action of the second spring to position and buffer the electrode rod. At this time, the second spring is compressed, and the electrode rod is further fixed in the limiting area formed between the four clamping jaws 101 under the action of the second spring.

[0045] Further optimization, a second pull ring 118 is installed on the third connecting rod 117, and the second pull ring 118 is used to connect with the driving device. When hoisting the electrode rod, the second driving device connected to the second pull ring 118 cooperates with the first driving device connected to the rotating plate assembly 102 to move the driving clamp to the position corresponding to the electrode rod; the first rotating plates 107 and the second rotating plates 108 rotatably connected in the two rotating plate assemblies 102 move downward together with the second pull ring 118 to contact the electrode rod under the action of the second driving device, and at this time, the first driving device connecting the two first rotating plates 107 and the two second rotating plates 108 drives the first rotating plates 107 and the second rotating plates 108 to rotate downward away from the rotating shaft 109, and the clamping jaws 101 connected to the first rotating plates 107 and the second rotating plates 108 are in an open state.

[0046] A rubber layer is disposed at the bottom of the second pressing plate 119. The rubber layer disposed at the bottom of the second pressing plate 119 can increase the friction between the second pressing plate 119 and the electrode rod, further preventing the electrode rod from sliding in the limiting area in the clamping jaw 101.

[0047] Embodiment 3

[0048] See also Figure 1-Figure 3 This embodiment is further optimized on the basis of the first embodiment. Both the first pressing plate 115 and the second pressing plate 119 are arc-shaped pressing plates, and the arc-shaped surfaces of the first pressing plate 115 and the second pressing plate 119 are in contact with the surface of the electrode rod. By setting the surface of the first pressing plate 115 and the second pressing plate 119 in contact with the electrode rod as an arc surface, the effect of the first pressing plate 115 and the second pressing plate 119 on limiting and fixing the electrode rod can be further improved, and the electrode rod can be prevented from sliding in the limiting area formed between the clamping jaws 101.
