Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a graphite sagger lifting device. Background Art

[0002] During the forward rotation of the roller rod driven by the transmission motor in the roller furnace, if the roller rod breaks, climbs, moves forward or backward, the graphite sagger will fall or get stuck. At this time, the graphite sagger needs to be lifted to prevent the sagger from arching or secondary damage due to broken rods.

[0003] In the prior art, a crowbar is usually used to lift the graphite sagger through the principle of leverage, and then maintenance is carried out. In the process of lifting the graphite sagger, the force fulcrum is on the outside, which causes uneven force on the graphite sagger and makes it easy to fall again. At the same time, it is affected by the smoke in the roller furnace, and it is impossible to confirm whether the graphite sagger is completely lifted, and normal maintenance cannot be carried out.

[0004] Therefore, it is urgent to provide a novel graphite sagger lifting device to solve the above-mentioned technical problems in the prior art. Utility Model Content

[0008] Optionally, the driving mechanism includes a driving member and a guide rod, the guide rod is used to be fixed to the inside of the roller furnace, the output end of the driving member is connected to the bottom of the two lifting rods, and the bottom of the lifting rod is slidably connected to the guide rod.

[0009] Optionally, a guide block is hinged at the bottom of the lifting rod, the guide block is slidably connected to the guide rod, and the output end of the driving member is connected to the guide block.

[0026] Please refer to Figure 1The graphite sagger lifting device is used for lifting the graphite sagger in the roller furnace. The graphite sagger lifting device comprises a lifting platform 100, a driving mechanism 300 and two lifting rods 200 arranged opposite to each other. The lifting platform 100 is used to carry the graphite sagger; the top of the lifting rod 200 is hinged to the bottom of the lifting platform 100, and the bottoms of the two lifting rods 200 can approach or move away from each other to drive the lifting platform 100 to move up and down; the output end of the driving mechanism 300 is connected to the bottom of the two lifting rods 200, and is used to drive the bottoms of the two lifting rods 200 to approach or move away from each other.

[0027] In this embodiment, when the graphite sagger lifting device is used, the graphite sagger lifting device is first installed in the roller furnace, and then the driving mechanism 300 drives the bottoms of the two lifting rods 200 to move closer or farther from each other. Since the tops of the lifting rods 200 are hinged and fixed to the bottom of the lifting platform 100, during the movement of the bottom of the lifting rods 200, the tops of the lifting rods 200 also drive the lifting platform 100 to lift or lower, thereby lifting the graphite sagger. The graphite sagger lifting device has a simple and compact structure, can operate in a smaller space, and moves smoothly during the lifting process. The graphite sagger on the lifting platform 100 is not easy to fall, which can ensure that the maintenance work of the graphite sagger in the roller furnace is carried out reliably and safely.

[0028] Furthermore, the driving mechanism 300 includes a driving member 310 and a guide rod 320, wherein the guide rod 320 is used to be fixed to the inside of the roller furnace, and the output end of the driving member 310 is connected to the bottom of the two lifting rods 200, and the bottom of the lifting rods 200 is slidably connected to the guide rod 320. The setting of the guide rod 320 can stably fix the graphite sagger lifting device inside the roller furnace, and guide the bottom of the lifting rod 200, so as to ensure that the guide rod 320 moves smoothly under the drive of the driving member 310, and ensure that the process of lifting the graphite sagger is carried out smoothly.

[0029] In this embodiment, a guide block 210 is hinged at the bottom of the lifting rod 200, the guide block 210 is slidably connected to the guide rod 320, and the output end of the driving member 310 is connected to the guide block 210. The lifting rod 200 is hinged to the guide block 210, and the guide block 210 is slidably connected to the guide rod 320, which can reduce the friction between the guide block 210 and the guide rod 320, thereby further ensuring the smooth movement of the bottom of the guide rod 320.

[0030] Specifically, the above-mentioned driving member 310 is a rotary driving mechanism 300. The output end of the rotary driving mechanism 300 is connected with a bidirectional lead screw 330, and the guiding block 210 is in threaded connection with the bidirectional lead screw 330 in a matching manner. It can be conceived that the rotary driving mechanism 300 can be selected as a servo motor, or a steering wheel rotated manually by manpower, etc. Using the threaded connection between the bidirectional lead screw 330 and the guiding blocks 210 of the two guiding rods 320 can drive the two guiding blocks 210 to approach or move away from each other during the rotation of the bidirectional lead screw 330, so as to move towards each other. Its structure is simple and reliable, and the driving is stable, and the mutual approach or separation of the guiding blocks 210 can be realized at low cost.

[0031] In an alternative embodiment, when the lifting platform 100 is in the lowest position, the distance between the tops of the two lifting rods 200 is less than the distance between the bottoms of the two lifting rods 200. That is to say, the two lifting rods 200 are in a "V" shape. During the process of the bottoms of the two lifting rods 200 approaching each other, the lifting of the tops of the lifting rods 200 can be realized, and the lifting platform 100 can be lifted smoothly.

[0032] Furthermore, two limiting structures 332 are oppositely arranged on the bidirectional lead screw 330, and the distance between the two limiting structures 332 is greater than the distance between the tops of the two lifting rods 200. In this embodiment, the limiting mechanism is the smooth rod part between the threaded parts 331 with two different spiral directions in the bidirectional lead screw 330. The guiding block 210 cannot rotate on the smooth rod part, so as to realize the limitation of the smooth rod part on the guiding block 210. The setting of the limiting mechanism can prevent the driving member 310 from driving the guiding block 210 to move beyond the range, so as to avoid the collision of the guiding block 210 or the sudden descent of the lifting platform 100 after exceeding a certain range, and can further ensure the smooth lifting of the lifting platform 100.

[0033] In another alternative embodiment, the two lifting rods 200 are cross-arranged and the two lifting rods 200 are hinged to each other. That is to say, the two lifting rods 200 are arranged in an X shape. As the included angle between the two lifting rods 200 decreases, the two lifting rods 200 can be made to approach each other, so as to lift the lifting platform 100 and realize the lifting of the graphite crucible.

[0034] It can be conceived that the two lifting rods 200 can also be in a "Λ" shape. During the process of the bottoms of the two lifting rods 200 moving away from each other, the lifting of the lifting platform 100 can also be realized, which will not be elaborated here.

[0035] Please continue to refer to Figure 1The driving mechanism 300 further includes a controller 340, which is communicatively connected to the driving member 310, and is used to control the switch, power and output speed of the driving member 310. In this embodiment, the controller 340 is an encoder, a computer or a PLC (Programmable Logic Controller), preferably an encoder, the encoder sensing is not interfered by the smoke in the roller furnace, and the encoder is used to determine the stroke of the bottom of the lifting rod 200, so as to prevent the occurrence of excessive lifting and the like, and ensure that the maintenance work is carried out reliably and safely.

[0036] Furthermore, the controller 340 is also communicatively connected to an in-place sensor, which can be fixed in the roller furnace and detect whether the graphite sagger is lifted to a preset position. The setting of the in-place sensor enables the controller 340 to stop the operation of the driving member 310 after receiving that the graphite sagger is lifted to a preset position. The preset position is a position where the operator can conveniently maintain, replace and overhaul the graphite sagger. The graphite sagger is overhauled at this preset position to prevent the occurrence of excessive lifting and the like.

[0037] The in-place sensor can be a commercially available one such as an in-place detection switch, a travel switch, a photoelectric sensor, etc., as long as it can detect the position of the graphite sagger or detect whether the graphite sagger is lifted to a preset position, and is not specifically limited in this embodiment.

[0038] In this embodiment, the lifting rod 200 includes a plurality of rods 201 arranged in parallel, the top of the rod 201 is hinged to the bottom of the lifting platform 100, and the bottoms of the two rods 201 arranged opposite to each other can be close to or away from each other. Specifically, each lifting rod 200 includes two rods 201 and the two rods 201 are symmetrically arranged about the guide rod 320. In this embodiment, the lifting rod 200 includes a plurality of rods 201, so that the lifting platform 100 is fully supported and driven by multiple positions of the lifting platform 100, and the support and drive process is more stable and reliable, which can further ensure the stable movement of the lifting platform 100, thereby preventing the graphite sagger from falling off.

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
