Technical Field

The invention relates to the field of isostatic graphite processing equipment, in particular to a safe hoisting mechanism for transporting isostatic graphite rods.

Background technique

In the production process of isostatic graphite rods, the powder needs to be filled into the rubber mold first, and then the rubber mold is sealed and transferred to the isostatic press to be pressed into rods. The rods are then calcined and graphitized to obtain isostatic graphite rods.

The technical solution of the present invention will be further described below with reference to FIG. 1 and FIG. 2 through specific embodiments.

The safe lifting mechanism for transporting isostatic graphite rods as shown in Figure 1 includes: a crossbeam 1, a fixed hanger 2, a movable hanger 3, a carrier 4, a clamp 5, a first slide 7 and a second slide 6. A first slide rail 21 is horizontally arranged at the bottom of the crossbeam 1, and the fixed hanger 2 is vertically arranged at the bottom of the crossbeam 1 and located in front of one end of the first slide rail 21. The top of the fixed hanger 2 is fixed to the crossbeam 1 by welding or screws, and the structure is stable.

The first slide 7 is arranged below the first slide rail 21 so as to be movably disposed. In this embodiment, a first slider 8 corresponding to the first slide rail 21 is arranged on the top of the first slide 7, which improves the lateral stability of the first slide 7. The movable suspension rod 3 is vertically arranged at the bottom of the first slide 7 and moves laterally with the first slide 7. Lifting ears 16 are symmetrically arranged on the crossbeam 1, which are convenient for connecting with the hook on the crane through two steel wire ropes for lifting.

A first motor 11 is laterally arranged on the fixed suspension rod 2, and a screw rod 25 that horizontally penetrates the movable suspension rod 3 is connected to the rotating shaft of the first motor 11. A nut 24 corresponding to the screw rod 25 is arranged in the movable suspension rod 3. The rotation of the first motor 11 can be controlled by PLC to realize the lateral adjustment of the movable suspension rod 3 to adapt to isostatic graphite rods of different lengths.

The second slide 6 is arranged on the inner side of the fixed boom 2 and the movable boom 3 so as to be liftable. In the present embodiment, a second slide rail 22 is vertically arranged on the inner side of the fixed boom 2 and the movable boom 3, and a second slider 17 corresponding to the second slide rail 22 is arranged on the back side of the second slide 6, thereby improving the lifting and lowering stability of the second slide 6.

In order to achieve the synchronous lifting and lowering of the two second slides 6 on the inner side of the fixed boom 2 and the movable boom 3, in the present embodiment, a second motor 12 is horizontally arranged on the fixed boom 2, and an extension rod 14 horizontally passing through the movable boom 3 is connected to the rotating shaft of the second motor 12. The rotation of the second motor 12 can be controlled by PLC to drive the extension rod 14 to rotate at a fixed angle.

The extension rod 14 is provided with a first sprocket 15 located above the second slide seat corresponding to the inner side of the fixed suspension rod 2. In addition, a second sprocket 9 is provided below the first slide seat 7 and is sleeved on the extension rod 14 and located above the second slide seat corresponding to the inner side of the movable suspension rod 3. In this embodiment, the extension rod 14 is a square rod, and a square hole corresponding to the square rod is provided in the second sprocket 9, which can ensure that the second sprocket 9 rotates with the extension rod 14 without affecting the relative transverse movement of the second sprocket 9 on the extension rod 14. A U-shaped baffle 10 with openings pointing downwards on both sides of the second sprocket 9 is provided below the first slide seat 7, so that the second sprocket 9 moves transversely with the first slide seat 7.

As shown in FIG. 1 , the first sprocket 15 and the second sprocket 9 are respectively provided with chains 27 connected to the corresponding second slides 6 therebelow. When the first sprocket 15 and the second sprocket 9 rotate with the extension rod 14, the chains 27 are rolled up or lowered to achieve synchronous lifting and lowering adjustment of the two second slides 6.

The clamping jaw 5 is arranged on one side of the second slide 6 and points downward. In the present embodiment, the clamping jaw 5 is an electric clamping jaw, and the extension and retraction of the clamping jaw 5 can be controlled by PLC to clamp the two ends of the isostatic graphite rod.

The carrier 4 is laterally movably arranged at the bottom of the fixed hanger 2 and the movable hanger 3, and a third slide rail 23 is arranged on the top of the carrier 4 on both sides of the isostatic graphite rod positioning groove 26, and a third slider 20 corresponding to the third slide rail 23 is arranged at the bottom of the fixed hanger 2 and the movable hanger 3, thereby improving the lateral movement stability of the carrier 4.

An isostatic graphite rod positioning groove 26 is concavely arranged on the top of the carrier 4, as shown in FIG2 , the isostatic graphite rod positioning groove adopts a U-shaped groove or a V-shaped groove, which can be used to lift and limit the lower end of the isostatic graphite rod, and has high stability. A rack 19 is arranged on one side of the third slide rail 23, and a third motor 13 is vertically arranged on the outer side of the fixed suspension rod 2 and the movable suspension rod 3. A gear 18 meshing with the rack 19 is arranged on the rotating shaft of the third motor 13. The rotation of the third motor 13 is controlled by PLC to drive the rotation of the gear 18, so as to realize the lateral movement of the third slide rail 23 and the carrier 4, and the degree of automation is high.

As shown in FIG1 , the second slide 6 first drives the clamp 5 to move downward to clamp the two ends of the isostatic graphite rod, and then the second slide 6 drives the clamp 5 and the isostatic graphite rod to slightly lift, and then the carrier 4 moves inward to the bottom of the end of the isostatic graphite rod to lift and limit, thereby avoiding the problem of falling during the lifting process.
