Description

Technical Field

[0001] The utility model relates to the field of cooling and conveying graphite electrodes, and more specifically to a lifting device and a graphite rod material cooling and conveying device having the lifting device. Background Art

[0002] In the prior art, the length of the graphite rod is much greater than its diameter. The fired graphite rod needs to be cooled, and there is a height difference between the bottom surface of the cooling pool and the conveying platform.

[0003] Traditional conveying devices usually use a motor-driven conveyor belt for transmission, and are generally used to transport products such as boxes or cans. Most of these products have a bottom surface that can stably support their main body so that they do not slide with the movement of the conveying device. The transmission plane of traditional conveying devices is usually located on a plane, and a robot arm is required to grab when it needs to be lifted or lowered.

[0004] However, during use, the traditional conveying device cannot meet the requirements of conveying and transporting the bar materials. The bar materials will roll on the traditional conveying device, and the cost of the manipulator is high and the structure is complex.

[0005] Therefore, how to provide a conveying device that can meet the needs of conveying bar-type products and can also solve the problem of conveying between broken tables with a simple structure is an urgent problem that technical personnel in this field need to solve. Utility Model Content

[0006] In view of this, the utility model provides a lifting device and a graphite rod cooling and conveying device having the same, aiming to solve the above technical problems.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A lifting device, comprising:

[0009] A bracket, wherein the bracket includes guide grooves arranged on both sides thereof, the guide grooves are fastened to the bracket, and the guide grooves are composed of a vertical section at the bottom and a curved section at the top;

[0010] A lifting part, the lifting part includes a lifting frame, both ends of the lifting frame are rotatably connected with roller assemblies, and the roller assemblies are slidably connected to the inner side of the guide groove;

[0011] A lifting power unit is installed at the top of the bracket and is used to drive the lifting frame to move up and down along the guide groove.

[0012] Through the above technical scheme, the utility model realizes the transmission between the broken tables through a simple structure. The vertical section at the bottom of the guide groove is the guide during the upward process of the graphite rod. The curved section at the top of the guide groove realizes the transmission of the graphite rod. After reaching the specified height, its curved shape drives the lifting part to tilt to one side, thereby transmitting the graphite rod to the right place. The structure is simple, the transmission process is stable, and the graphite rod is automatically unloaded after reaching the specified height.

[0013] Preferably, the lifting frame comprises a V-shaped groove plate, both ends of the V-shaped groove plate are fastened with baffles, and the two baffles are rotatably connected to the roller assembly at the back-to-back sides.

[0014] The beneficial effects of the above technical solution are as follows: the V-shaped structure ensures that the graphite rods are always located at the bottom of the V-shaped groove plate under the action of gravity during the lifting process, and will not roll; the baffles at both ends of the V-shaped groove plate prevent the graphite rods from sliding out along the two ends of their length direction during the lifting process, making the transmission process more stable.

[0015] Preferably, the bracket further comprises a cross beam, both ends of the bottom surface of the cross beam are fixed with vertical frames, the inner side of the vertical frames are fastened with side mounting plates, and the guide grooves are fastened with the side mounting plates.

[0016] The beneficial effect of the above technical solution is that the guide groove is fastened to the stand through the side mounting plate, thereby improving the stability of the overall structure of the guide groove.

[0017] Preferably, the lifting power unit includes a first servo motor and an iron rope, the first servo motor is installed on the upper surface of the beam, the power output end of the first servo motor is fastened to a pulley, one end of the iron rope is fixed to the pulley, and the other end is fastened to the lifting frame.

[0018] The beneficial effect of the above technical solution is that the first servo motor can control the lifting frame to move up and down through the iron rope wound around the rope pulley.

[0019] The utility model also provides a graphite rod cooling and conveying device, wherein a cooling pool, the above-mentioned lifting device, a reversing part and a weighing part are sequentially arranged along the conveying direction;

[0020] The bottom of the cooling pool is fixed with a plurality of spaced bosses along the conveying direction, and the bosses are arranged obliquely;

[0021] The lifting portion is located at one end of the cooling pool and at a lower side of the inclined direction of the boss;

[0022] The reversing portion is sequentially arranged with a first tilting frame, a rotating portion and a second tilting frame along the conveying direction;

[0023] The weighing unit is provided in a post-process of the second tilting frame.

[0024] Through the above technical scheme, the utility model realizes that the graphite rods roll along the conveying direction under the action of gravity without the participation of power through the overall inclined arrangement between the cooling pool input end, the lifting part and the reversing part, thereby reducing costs, simplifying the structure and stabilizing the conveying process.

[0025] Preferably, the opening end of the lifting frame faces upward, and a plurality of front forks are rotatably connected to one side edge of the opening end facing the boss, and the boss and the front forks are arranged alternately.

[0026] Preferably, the upper surface of the front fork is flush with the inner surface of the lifting frame, and the front fork has a positioning surface and is in contact with the lower surface of the lifting frame.

[0027] The beneficial effects of the above two technical solutions are as follows: the positioning surface of the front fork contacts the lower surface of the lifting frame and is rotatably connected to the open end of the lifting frame, so that the rotation direction of the front fork can only rotate unidirectionally toward the inner surface of the V-groove plate, and the front fork and the bosses are arranged alternately, so that when the support frame is descending, the front fork will contact the rod stock through the space between the bosses, and the front fork will rotate upward when contacting the rod stock. Then, in the process of continuing to descend, the front fork will return to a state flush with the inner surface of the lifting frame under the action of gravity after there is no interference from the rod stock. Then, in the process of rising, since the rotation direction of the front fork can only rotate unidirectionally toward the inner surface of the V-groove plate, the graphite rod stock located on the boss can be transferred to the lifting frame through the front fork.

[0028] Preferably, the boss has a stopper at one end close to the lifting portion.

[0029] The beneficial effects of the above technical solution are as follows: during the rolling process of the graphite rod on the inclined surface of the boss, the stopper limits the rod at one end of the boss located at the lifting part, and multiple graphite rods are arranged in sequence under the limiting action of the stopper, so that the lifting frame can convey the graphite rods individually during the conveying process.

[0030] Preferably, according to the graphite rod cooling and conveying device described in the claim, the upper surfaces of the first inclined rack and the second inclined rack are gradually inclined downward along the conveying direction.

[0031] Preferably, the rotating part includes a second servo motor, a power output end of the second servo motor is fastened to a rotating platform, a material receiving end of the rotating platform switches between the first tilting frame and the second tilting frame, and the other end of the rotating platform has a gear frame. When the material receiving end of the rotating platform is switched to correspond to the first tilting frame, the end surface heights of the rotating platform and the opposite surfaces of the first tilting frame are consistent, and when the material receiving end of the rotating platform is switched to correspond to the second tilting frame, the upper surface of the rotating platform and the upper surface of the second tilting frame remain flush.

[0032] The beneficial effects of the above two technical solutions are as follows: the bar material rolls down from the lifting frame onto the first inclined frame, and under the action of gravity and the inclination angle of the first inclined frame, the bar material can roll onto the rotating platform, and the gear frame of the rotating platform limits the movement of the bar material. When the material receiving end of the rotating platform is switched to correspond to the second inclined frame, the bar material rolls down onto the second inclined frame under the action of gravity, and then enters the weighing part through the inclined surface of the second inclined frame.

[0033] It can be seen from the above technical solutions that, compared with the prior art, the utility model discloses a lifting device and a graphite rod cooling and conveying device having the same, which has the following beneficial effects:

[0034] 1. The utility model is used for transmission between platforms with different heights. The lower vertical section of the guide groove and the upper curved section are arranged. The lower vertical section of the guide groove can provide guidance during the upward process of the graphite rods. The curved section of the upper guide groove makes the graphite rods reach the specified height. The curved shape drives the lifting part to tilt to one side, thereby transmitting the graphite rods to the designated height. The utility model has a simple structure and a stable transmission process. The graphite rods are automatically unloaded after reaching the specified height.

[0035] 2. The main body of the lifting frame is a V-shaped structure coordinated with the upper and lower sections of the guide groove. When the lifting frame rises in the vertical section of the guide groove, the graphite rods are always located at the bottom of the V-shaped groove plate, and the transmission is stable. When the lifting frame rises to the curved section of the guide groove, the side of the V-shaped groove plate tilts, and the graphite rods can roll out naturally without manual intervention.

[0036] 3. The utility model arranges the overall conveying table surface in an inclined manner. Between the cooling pool input end, the lifting part and the reversing part, the graphite rod rolls along the conveying direction under the action of gravity without the participation of power, thereby reducing costs, having a simple structure and a stable conveying process.

[0037] 4. The unidirectional rotation setting of the front fork combined with the staggered arrangement of the front fork and the bosses enables the lifting frame to extract the graphite rods by simply descending below the graphite rods and then rising again, which is easy to operate and efficient.

[0038] 5. One end of the boss close to the lifting part is provided with a stopper combined with a front fork, so that the lifting frame can convey the graphite rods individually during the conveying process, which is convenient for subsequent operations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0053] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0054] Embodiment 1;

[0055] See attached Figure 1-3 , the embodiment of the utility model discloses a lifting device, including: a bracket 21, a lifting part 22 and a lifting power part 23;

[0056] The bracket 21 includes guide grooves 211 disposed on both sides thereof, the guide grooves 211 are fastened to the bracket 21, and the guide grooves 211 are composed of a vertical section at the bottom and a curved section at the top;

[0057] The lifting part 22 includes a lifting frame 221, and roller assemblies 222 are rotatably connected at both ends of the lifting frame 221, and the roller assemblies 222 are slidably connected to the inner side of the guide groove 211;

[0058] The lifting power unit 23 is installed at the top of the bracket 21 and is used to drive the lifting frame 221 to move up and down along the guide groove 211 .

[0059] In this embodiment, the vertical section at the bottom of the guide groove 211 and the curved section at the top are tangent at the connection, so that the lifting portion 22 is smoother when rising and falling in the guide groove 211 .

[0060] In order to further optimize the above technical solution, the lifting frame 221 includes a V-shaped groove plate 2211, both ends of the V-shaped groove plate 2211 are fastened with baffles 2212, and the two baffles 2212 are rotatably connected to the roller assemblies 222 at the back to face.

[0061] In this embodiment, the roller assembly 222 includes two rollers. When the lifting frame 21 is located in the vertical section, the two rollers are rotated in the vertical direction and connected to the baffle 2212. When the roller located at the top abuts against the top of the guide groove 211, the angle between the line connecting the two rollers and the vertical direction is greater than the angle between the internal inclined surface of the V-shaped groove plate 2211 and the horizontal plane when the lifting frame 21 is located in the vertical section. Therefore, when the lifting frame 21 is located at the top of the guide groove 211, the overall inclination direction of the lifting frame 21 is greater than the inclination angle of the internal inclined surface of the V-shaped groove plate 2211, and the graphite rod material can roll from the lifting frame to the next sequence under the action of gravity.

[0062] In order to further optimize the above technical solution, the bracket 21 also includes a cross beam 212, and vertical frames 213 are fixed at both ends of the bottom surface of the cross beam 212 along the length direction. The inner side of the vertical frame 213 is fastened with a side mounting plate 214, and the guide groove 211 is fastened with the side mounting plate 214.

[0063] In order to further optimize the above technical solution, the lifting power unit 23 includes a first servo motor 231 and an iron rope 232. The first servo motor 231 is installed on the upper surface of the beam 212. The power output end of the first servo motor 231 is fastened with a pulley 233. One end of the iron rope 232 is fixed to the pulley 233, and the other end is fastened to the lifting frame 221.

[0064] In this embodiment, there are two lifting power units 23, which are installed on the upper surface of the beam 212 and correspond to the baffles 2212 at both ends of the lifting frame 221. The beam 212 is provided with avoidance holes on the connection path of the iron rope 232, thereby improving the stability of the lifting frame 221 during the rising process.

[0065] The specific principle of the lifting device provided in this embodiment is:

[0066] The first servo motor 231 controls the lifting frame 221 to rise by controlling the iron rope 232 connected between the rope pulley 233 and the lifting frame 221. The two ends of the lifting frame 221 are rotatably connected to rollers arranged up and down, and the rollers slide and abut on the inner side of the guide groove 211. During the rising process, the curved section at the upper part of the guide groove 211 makes the rollers arranged up and down no longer on the same vertical line, thereby causing the lifting frame 221 to tilt.

[0067] Embodiment 2;

[0068] See attached Figure 4 The utility model embodiment discloses a graphite rod cooling and conveying device, wherein a cooling pool 1, a lifting device of embodiment 1, a reversing part 3 and a weighing part 4 are sequentially arranged along a conveying direction 100;

[0069] A plurality of spaced bosses 11 are fixed to the bottom of the cooling pool 1 along the conveying direction 100, and the bosses 11 are arranged obliquely;

[0070] The lifting portion 22 is located at one end of the cooling pool 1 and at the lower side of the inclined direction of the boss 11;

[0071] The reversing portion 3 is sequentially arranged with a first tilting frame 31, a rotating portion 32 and a second tilting frame 33 along the conveying direction 100;

[0072] The weighing unit 4 is provided in a post-process of the second tilting frame 33 .

[0073] In this embodiment, the weighing part 4 is arranged horizontally.

[0074] See attached Figure 5-7 The opening end of the lifting frame 221 faces upward, and a plurality of front forks 223 are rotatably connected to one side edge of the opening end toward the boss 11, and the boss 11 and the front forks 223 are arranged alternately.

[0075] In this embodiment, the front fork 223 is rotatably connected to the open end of the lifting frame 221 via a pin shaft 224 .

[0076] Specifically, the lower surface of the front fork 223 located above the open end of the lifting frame 221 has an inclined surface, so that the inclination angle of the front fork 223 can be reduced during the interference between the front fork 223 and the graphite rod when the lifting frame 221 descends.

[0077] More specifically, the weight of the front fork 223 on one side above the open end of the lifting frame 221 is greater than the weight of the other side, and the rotation range of the front fork 223 is between the initial state and flush with the vertical direction. Therefore, the interference between the front fork 223 and the graphite rod causes it to automatically return to the initial state after rotation.

[0078] In order to further optimize the above technical solution, the upper surface of the front fork 223 is flush with the inner surface of the lifting frame 221 , and the front fork 223 has a positioning surface 2231 that contacts the lower surface of the lifting frame 221 .

[0079] See attached Figure 8 The boss 11 has a stopper 111 at one end close to the lifting portion 22 .

[0080] See attached Figure 9-12 The upper surfaces of the first inclined frame 31 and the second inclined frame 33 are gradually inclined downward along the conveying direction 100.

[0081] In order to further optimize the above technical solution, the rotating part 32 includes a second servo motor 321, and the power output end of the second servo motor 321 is fastened to a rotating platform 322. The material receiving end of the rotating platform 322 switches between the first tilting frame 31 and the second tilting frame 33. The other end of the rotating platform 322 has a gear frame 323. When the material receiving end of the rotating platform 322 is switched to correspond to the first tilting frame 31, the end surface heights of the rotating platform 322 and the opposite surfaces of the first tilting frame 31 are consistent. When the material receiving end of the rotating platform 322 is switched to correspond to the second tilting frame 33, the upper surface of the rotating platform 322 and the upper surface of the second tilting frame 33 remain flush.

[0082] The specific principle and use method of the graphite bar cooling and conveying device provided in this embodiment are as follows:

[0083] 1. Under the action of gravity, the graphite rods gradually roll down along the inclined bosses 11 along the conveying direction 100 toward the depth of the cooling pool 1;

[0084] 2. The graphite rod rolls to the end of the boss 11 with the stopper 111 and stops rolling;

[0085] 3. The first servo motor 231 controls the lifting frame 221 to descend, and when the front fork 223 contacts the graphite rod, it is lifted upward. After passing through the graphite rod, the upper surface of the front fork 223 and the inner surface of the lifting frame 221 are restored to a flush state;

[0086] 4. The first servo motor 231 controls the lifting frame 221 to rise, and the front fork 223 lifts the graphite rod, and the graphite rod rolls to the middle position of the V-groove plate 2211 under the action of the inclined surface of the V-groove plate 2211;

[0087] 5. Continue to rise, the curved section at the upper part of the guide groove 211 makes the rollers arranged at both ends of the lifting frame 221 no longer on the same vertical line, thereby causing the lifting frame 221 to tilt, and the graphite rods roll from the lifting frame 22 to the first tilting frame 31;

[0088] 6. The graphite rods can roll onto the rotating platform 322 under the action of gravity and the inclination angle of the first inclined frame 31;

[0089] 7. The rotating platform 322 switches to the second inclined rack 33, and the graphite rods roll onto the second inclined rack 33 under the action of gravity, and then enter the weighing part through the inclined surface of the second inclined rack 33 to complete the transmission.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
