DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] See also Figure 1 and Figure 2 The utility model provides a technical solution: a hand holding device for an electroslag furnace, comprising a support arm 1, an electrode load-bearing frame 2 is installed on the top of the support arm 1, a weighing device 3 is installed between the support arm 1 and the electrode load-bearing frame 2, a connecting frame 4 that passes through the support arm 1 is fixedly connected to the bottom of the electrode load-bearing frame 2, an assembly frame 5 is fixedly connected to the bottom of the connecting frame 4, and a clamping component 6 is installed in the assembly frame 5.

[0015] There are at least two groups of weighing devices 3, and the two groups of weighing devices 3 are symmetrically distributed on the left and right sides of the center of the electrode load-bearing frame 2. The weighing devices 3 are composed of an upper fixed plate, a lower fixed plate and a pressure detection sensor. The pressure detection sensor is electrically connected to an external computer or other control unit. The upper fixed plate is fixedly connected to the bottom of the electrode load-bearing frame 2, and the lower fixed plate is fixedly connected to the top of the support arm 1. When the clamping assembly 6 clamps the electrode 8, the electrode load-bearing frame 2 presses down the pressure detection sensor, and the detected values ​​are transmitted to the computer through the pressure detection sensors on both sides. The average pressure value obtained by the computer can be used to calculate and display the weight of the electrode 8 to complete the weighing operation.

[0016] like Figure 1 As shown in the figure, a guide mechanism 7 is installed between the electrode load-bearing frame 2 and the support arm 1, and the guide mechanism 7 includes a guide shaft 71 and a guide sleeve 72. The guide sleeve 72 is made of insulating material, and the guide sleeve 72 is fixedly connected to the top of the support arm 1, and the guide shaft 71 is fixedly connected to the bottom of the electrode load-bearing frame 2. The guide shaft 71 passes through the middle of the guide sleeve 72. The guide shaft 71 and the guide sleeve 72 are arranged to cooperate with each other. When the clamping assembly 6 clamps and fixes the electrode 8, the moving stroke of the electrode load-bearing frame 2 is limited and guided. By arranging the guide mechanism 7, the swinging and floating of the electrode load-bearing frame 2 during the weighing process of the electrode 8 can be reduced, and the stability of the weighing process can be increased, so that the weighing readings can be more accurate.

[0017] like Figure 2 As shown in , the clamping assembly 6 includes a hydraulic cylinder 61, and the output end of the hydraulic cylinder 61 is fixedly connected to a clamping arm 62, and the clamping arm 62 is rotatably connected to the assembly frame 5. A first arc groove 63 is integrally formed in the assembly frame 5, and a second arc groove 64 is integrally formed in the clamping arm 62. The first arc groove 63 and the second arc groove 64 constitute a clamping groove 65, and the side walls of the first arc groove 63 and the second arc groove 64 are respectively fixedly equipped with conductive blocks 66, and the conductive blocks 66 are respectively adapted to the curvature of the first arc groove 63 and the second arc groove 64. The input end of the hydraulic cylinder 61 is connected to an external hydraulic pipeline, and the action of the output end of the hydraulic cylinder 61 is controlled by the external hydraulic pipeline. After the output end of the hydraulic cylinder 61 is actuated, it can drive the clamping arm 62 to cooperate with the conductive block 66 to clamp and fix the electrode 8.

[0018] This device changes the electrode clamping form of the traditional support arm arm structure for the electroslag furnace, and solves the fact that the position of the consumable electrode is easily changed and the gas protection device cannot be installed due to the electrode clamping form of the electroslag furnace with this structure. By optimizing the geometric shape of the contact surface between the dummy electrode and the conductive copper block, the dummy electrode and the consumable electrode are accurately aligned with each other with the help of the clamping force of the arm, ensuring that the gas protection device can be used while increasing the conductive area and reducing the contact resistance, thereby reducing the voltage drop, saving electricity, increasing safety and improving production efficiency.
