Description

Technical Field

[0001] The utility model relates to the technical field of equipment, in particular to a special crane for taking out a crucible. Background Art

[0002] In the production process of graphite anode materials, crucibles play a vital role. They are used to hold raw materials, which are then sent into the Acheson furnace for high-temperature heating to eventually form finished graphite anode materials. However, during the production process, a thorny problem has long plagued the company, that is, the difficulty of removing the crucible from the furnace.

[0003] In the traditional production mode, the crucible is completely dependent on manual operation to remove the crucible from the furnace. Specifically, the crucibles are lifted one by one by the hook of the general crane and the wire rope is carried to remove them from the furnace. This primitive way of removing the crucible has many serious problems. First of all, from a safety perspective, since the crane hook and wire rope may cause accidents due to high temperature radiation, crucible shaking and other factors in the process of lifting the high-temperature crucible, the danger level is extremely high, and the operator is always facing safety threats such as burns and injuries. Secondly, from the perspective of the working environment, the furnace removal operation in a high temperature environment makes the surrounding air unbearably hot, and is accompanied by a large amount of dust and smoke. These harsh conditions seriously damage the health of workers. In such an environment for a long time, workers are very likely to suffer from respiratory diseases, heat stroke and other diseases. More importantly, the crucible after being heated at high temperature in the Acheson furnace has a fragile structure. In the process of lifting it with the hook and wire rope of the general crane, the crucible is easy to break due to uneven force or slight collision. Once the crucible breaks, not only will the graphite negative electrode material being processed be scrapped, causing direct economic losses, but the broken crucible fragments may also damage the equipment and affect the normal progress of subsequent production. The indirect economic losses are even more difficult to estimate. Utility Model Content

[0004] In order to solve the above problems, an embodiment of the utility model provides a special crane that can take the crucible out of the furnace through a lifting device, which can improve the efficiency of taking the crucible out of the furnace and reduce the loss of the crucible.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a special crane for crucible unloading, comprising a bridge frame, a traveling frame is arranged on the bridge frame, a clamping device for lifting the crucible is arranged at the lower part of the traveling frame, a driving source for driving the clamping device to lift and lower is arranged at the upper part of the traveling frame, the clamping device comprises a base, a clamping arm is arranged on one side of the base, and an anti-dumping assembly is arranged on the other side, a lifting pulley is arranged on the upper part of the base, and a lifting rope is arranged between the lifting pulley and the driving source.

[0006] As a further improvement of the above technical solution:

[0007] A guide sleeve is arranged in the middle of the traveling frame, a guide rod used in conjunction with the guide sleeve is arranged on the upper part of the base, a crossbeam is arranged on the upper part of the guide rod, and a driving motor for adjusting the height of the anti-dumping assembly is arranged on the crossbeam.

[0008] The anti-dumping assembly comprises a cross brace located above the base, a limit rod is arranged at the lower part of the cross brace, a movable pulley is arranged at the upper part of the cross brace, and a second hoisting rope is arranged between the movable pulley and the driving motor.

[0009] A limiting sleeve connected to the base is arranged outside the limiting rod.

[0010] A return spring sleeved on the limit rod is arranged in the limit sleeve, and a positioning ring plate abutting against the lower end of the return spring is arranged in the middle of the limit rod.

[0011] The clamping arm comprises a vertical rod connected to a base, a load-bearing plate is arranged at the lower part of the vertical rod, and the vertical rod and the load-bearing plate are distributed in an L shape.

[0012] The thickness of the load-bearing plate gradually decreases as it extends outward from one end connected to the vertical rod.

[0013] The number of the clamping arms is multiple and evenly distributed along the length direction of the base.

[0014] The beneficial effects of the embodiment of the utility model are as follows: the special crane for taking out the crucible from the furnace comprises a bridge frame, and walking beams are arranged at both ends of the bridge frame. The bridge frame moves along the length direction of the walking beams to take the crucible out of the furnace and then transport it to other directions. A walking frame is installed on the bridge frame, and a clamping device for lifting the crucible is arranged at the lower part of the walking frame, and a driving source for driving the clamping device to rise and fall is arranged at the upper part of the walking frame. The walking frame moves along the length direction of the bridge frame, and can realize the clamping and lifting operations of the crucibles at different positions in the furnace.

A lifting pulley is provided on the upper part of the base, and a lifting rope is provided between the lifting pulley and the driving source. The driving source adopts a motor, and the driving source is used to provide power for the lifting and lowering of the base, thereby driving the crucible to move upward to complete the crucible unloading operation. Compared with the conventional crucible unloading operation, there is no need for the operator to come into close contact with the crucible, and the operation is safer. At the same time, it can avoid the crucible from breaking during the lifting process, thereby improving the crucible unloading efficiency and reducing the loss of the crucible.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0022] like Figure 1-5 As shown, the special crane for taking out crucible from the furnace of this embodiment comprises a bridge frame 1, and walking beams are arranged at both ends of the bridge frame 1. The bridge frame 1 moves along the length direction of the walking beam to take the crucible out of the furnace and then transport it to other directions. A walking frame 2 is installed on the bridge frame 1, and a clamping device for lifting the crucible is arranged at the lower part of the walking frame 2. A driving source 3 for driving the clamping device to rise and fall is arranged at the upper part of the walking frame 2. The walking frame 2 moves along the length direction of the bridge frame 1, so as to realize the clamping and lifting operation of the crucible at different positions in the furnace. The clamping device comprises a base 4, and a clamping arm 5 is arranged on one side of the base 4, and a clamping arm 5 is arranged on the other side. An anti-dumping assembly is provided on one side, and the clamping arm 5 and the anti-dumping assembly are used to complete the clamping operation of the crucible. A lifting pulley 6 is provided on the upper part of the base 4, and a lifting rope 7 is provided between the lifting pulley 6 and the driving source 3. The driving source 3 adopts a motor, and the driving source 3 is used to provide power for the lifting and lowering of the base 4, thereby driving the crucible to move upward to complete the crucible unloading operation. Compared with the conventional crucible unloading operation, there is no need for the operator to come into close contact with the crucible, and the operation is safer. At the same time, it can avoid the crucible from breaking during the lifting process, thereby improving the crucible unloading efficiency and reducing the loss of the crucible.

[0023] A guide sleeve 8 is provided in the middle of the traveling frame 2, a guide rod 9 used in conjunction with the guide sleeve 8 is provided on the upper part of the base 4, a crossbeam 10 is provided on the upper part of the guide rod 9, and a driving motor 11 for adjusting the height of the anti-dumping assembly is provided on the crossbeam 10. The cooperation between the guide sleeve 8 and the guide rod 9 can guide and limit the lifting and lowering of the base 4, thereby preventing the crucible from falling due to the deflection of the base 4 during the rising process.

[0024] The anti-dumping assembly includes a cross brace 12 located above the base 4, a limit rod 13 is provided at the lower part of the cross brace 12, a movable pulley 20 is provided at the upper part of the cross brace 12, and a lifting rope 14 is provided between the movable pulley 20 and the drive motor 11. When the crucible is located on the clamping arm 5, the limit rod 13 is located on the outside of the crucible to prevent the crucible from falling outward.

[0025] A limiting sleeve 15 connected to the base 4 is disposed outside the limiting rod 13 , and the limiting sleeve 15 can provide guidance for the lifting and lowering of the limiting rod 13 .

[0026] A return spring 16 sleeved on the limit rod 13 is provided in the limit sleeve 15, and a positioning ring plate 17 abutting against the lower end of the return spring 16 is provided in the middle of the limit rod 13. When the driving motor 11 pulls the limit rod 13 upward, the crucible is taken out from the clamping arm 5. At this time, the return spring 16 is compressed. When clamping again, the driving motor 11 cancels the limit on the limit rod 13, and under the action of the return spring 16, the limit rod 13 is driven to move downward to the outside of the crucible. The limit rod 13 cooperates with the clamping arm 5 to clamp the crucible and complete the crucible out-of-furnace operation.

[0027] The clamping arm 5 includes a vertical rod 18 connected to the base 4. A load-bearing plate 19 is provided at the lower portion of the vertical rod 18. The vertical rod 18 and the load-bearing plate 19 are distributed in an L shape.

[0028] The thickness of the load-bearing plate 19 gradually decreases as it extends outward from one end connected to the vertical rod 18, so as to facilitate lifting the crucible from the bottom of the crucible.

[0029] There are multiple clamping arms 5 that are evenly distributed along the length direction of the base 4, so that batches of crucibles can be taken out of the furnace at a time, thereby improving the operating efficiency.
