Description

Carbon block crushing tool lifting mechanism

technical field

The invention relates to a lifting mechanism for a carbon block crushing tool to complete the action of carbon block crushing, and belongs to the technical field of carbon block crushing

Background technique

Carbon block crushing is one of the important sections in the anode assembly workshop. This section realizes the online crushing of carbon blocks. It is required that the anode should not break the carbon block on the catenary chain. Due to the large volume and high strength of the carbon block, Therefore, the crushing equipment must have a high overall strength and a huge crushing force. The crushing force comes from the lifting mechanism of the cutter, so a strong and stable lifting mechanism of the cutter is a prerequisite for crushing the carbon block. In the past, the structure of directly lifting the oil cylinder to generate the crushing force was used, but this structure requires the oil cylinder to have a large jacking force, so the size of the oil cylinder is large, and the jacking force of the oil cylinder has no amplification effect during the crushing process, which requires higher requirements for the oil cylinder. .

Contents of the invention

The technical problem to be solved by the present invention is to provide a carbon block crushing tool lifting mechanism, which can make the hydraulic cylinder have a force amplification effect during the jacking process.

Technical scheme of the present invention: the lifting mechanism of the carbon block crushing tool includes a frame 8 and a mechanism attachment 1 arranged above the frame 8, an anode rod 10 is installed in the mechanism attachment 1, and a movable knife rest 5 is arranged below the anode rod 10 , the blade 2 is arranged on the movable knife rest 5, and the link arm 3 is respectively arranged on both sides of the frame 8, the left end of the link arm 3 is connected with the frame 8, the middle part is connected with the movable knife rest 5, and the right end is connected with the beam 6 Connected, beam 6 is connected with oil cylinder 7.

A balance arm 4 is arranged below each link arm 3 , the left end of the balance arm 4 is connected to the frame 8 , and the right end is connected to the moving knife rest 5 .

The blades 2 have 1 to 5 pieces.

The centerlines of the anode rod 10 and the moving knife rest 5 are located on the same vertical line; the right end of the balance arm 4 and the connection point of the moving knife rest 5 and the middle part of the connecting rod arm 3 are located on the same vertical line, and are located on the same vertical line. On the vertical section passing through the centerline of the movable knife rest 5.

The link arm 3 and the balance arm 4 are connected with the frame 8 and the movable knife rest 5 through pin shafts.

The oil cylinder of the present invention is located at the rightmost end of the connecting rod arm, and the cutter is placed in the middle of the connecting rod arm. During the pushing out process of the oil cylinder, due to the difference in the length of the moment arm, nearly twice the Due to the strength of the jacking force of the oil cylinder, it is possible to achieve a relatively small oil cylinder to generate a huge crushing force for carbon block crushing, and at the same time reduce the size of the hydraulic cylinder and make the entire equipment structure more compact; the balance of the balance arm, Make the movable knife rest keep vertically upward when moving upwards, and finally complete the crushing action of the charcoal block.

Detailed ways

Embodiments of the present invention: the structure of the carbon block crushing tool lifting mechanism is as shown in Figure 1 and Figure 2, including a frame 8 and a mechanism accessory 1 arranged above the frame 8, an anode rod 10 is installed in the mechanism accessory 1, and the anode The bottom of bar 10 is provided with movable knife rest 5, and movable knife rest 5 is provided with 1 ~ 5 blades 2, is respectively provided with link arm 3 on both sides of frame 8, and the left end of link arm 3 is connected with frame 8. Connect, the middle part is connected with the movable knife rest 5, the right end is connected with the crossbeam 6, and the crossbeam 6 is connected with the oil cylinder 7. The bottom of each link arm 3 is provided with a balance arm 4 , the left end of the balance arm 4 is connected on the frame 8 , and the right end is connected on the movable knife rest 5 . The centerlines of the anode rod 10 and the movable knife rest 5 are located on the same vertical line; the connection point between the right end of the balance arm 4 and the movable knife rest 5, and the middle part of the connecting rod arm 3 are located on the same vertical line, and are located on the same vertical line after the moving On the vertical section of the centerline of the knife rest 5. The link arm 3, the balance arm 4 are connected with the frame 8 and the movable knife rest 5 through pin shafts.

When the carbon block 9 is fixed to the anode rod 10 of the mechanism accessory 1, the oil cylinder 7 is pushed out, driving the connecting rod arm 3 to rotate around the pin shaft, and at the same time, the moving knife rest 5 moves upward. Due to the balancing effect of the balance arm 4, the moving knife rest 5 Keep vertically upwards when moving upwards, and the blade 2 completes the crushing action of the carbon block 9 under the drive of the moving knife rest 5 .
