Description

Technical Field

[0001] The invention relates to the technical field of roasting overhead cranes, in particular to a novel roasting multifunctional overhead crane. Background Art

[0002] The baking multifunctional overhead crane is a key equipment specially used in the pre-baking anode workshop, which is used to transport carbon blocks, absorb fillers or place fillers.

[0003] As a special equipment, the existing roasting multifunctional overhead crane controls the gripper to grab the carbon blocks through a servo motor. It is difficult for the staff to judge the gripping condition of the gripper and whether the force is appropriate, which causes the carbon blocks to be easily damaged and broken due to excessive force when being clamped, making it inconvenient to carry the carbon blocks. The existing roasting multifunctional overhead crane efficiently absorbs the filler through a vacuum pipe, but when the vacuum equipment stops running, the filler in the pipe will fall out, resulting in a large deviation between the actual suction amount and the ideal suction amount. The existing roasting multifunctional overhead crane also includes a gas purification mechanism, which filters the filler powder in the air through a cloth belt. When cleaning the cloth belt, high-pressure gas is required to blow away the filler powder on the surface, which is costly and requires frequent replacement of high-pressure gas tanks, resulting in complicated operation.

[0015] Beneficial effects of the present invention: 1. The present invention squeezes the worm upward by squeezing the threaded column to rotate the worm, so that the worm wheel drives the threaded cylinder to rotate through the second sliding rod, so that the clamping plate is squeezed away from each other under the squeezing of the carbon block by the first clamping block and the second clamping block, thereby reminding the staff that the carbon block has been clamped, making it easy for the staff to identify the clamped state of the carbon block, avoiding the problem that the clamping state of the carbon block is difficult to identify.

The present invention rotates the fan blades through airflow, thereby driving the threaded plate to rotate upward along the rotating thread of the support plate, and the screen cloth rotates with the threaded plate under the action of damping. During the rotation of the threaded plate, the support plate slides into the first sliding groove of the threaded plate, causing the threaded plate to fall downward and drive the screen cloth to rotate. The threaded plate moves up and down to cause the knocking rod to reciprocate away from and knock the screen cloth. The screen cloth shakes and rotates at the same time, thereby efficiently and quickly shaking off the filler with a small particle size, reducing the cost of cleaning the screen cloth and improving the cleaning effect of the screen cloth; 3. The present invention expands and contracts the airflow through the expansion and contraction tube to increase the temperature of the airflow during heat dissipation. The air guide threads and heat dissipation rings inside the expansion and contraction tube increase the airflow heat dissipation time and heat dissipation area, thereby improving the cooling effect of the airflow and preventing the airflow from overheating and damaging the device. 4. The present invention generates low air pressure inside the first electric telescopic cylinder and the receiving port when the vacuum pump is used to draw air. The low air pressure causes the external air pressure to push the valve plate to open, thereby absorbing the filling material. During the process of closing the vacuum pump, the air pressure inside the first electric telescopic cylinder and the receiving port slowly increases, and the valve plate falls without being pushed by the external air pressure. During the falling process of the valve plate, the gap between the two gradually becomes smaller, thereby controlling the air flow speed, ensuring that the filling material in the first electric telescopic cylinder will not fall out, and preventing pollution to the pre-baked anode workshop.

The third pipeline 67 is connected between the second electric telescopic cylinder 51 and the conical shell 62, and the fourth pipeline 718 is connected between the second electric telescopic cylinder 51 and the valve shell 713. The bottom of the second electric telescopic cylinder 51 is fixedly connected with a discharge port 52.

Rectangular through grooves are opened on both sides of the bottom of the second electric telescopic cylinder 51, and a resistance is arranged in the rectangular through groove.

[0028] It also includes an impeller 58. A ratchet 57 is provided inside the storage barrel 5. The impeller 58 is rotatably connected inside the storage barrel 5. An elastic lever 59 is rotatably connected to the outer wall of the impeller 58. The elastic lever 59 is in contact with the ratchet 57 and can knock the ratchet 57 when rotating.

[0029] In the initial state, the two valve plates 44 are in sealing contact with each other, the two material blocking plates 53 are in sealing contact with each other, and the axis of the tapered through hole of the ball valve head 715 is kept horizontal, so that the sealing cylinder 71 and the fourth pipeline 718 cannot be connected through the tapered through hole of the ball valve head 715. When the staff needs to absorb the filling material in the pre-baked anode workshop, the staff first starts the rail trolley 2, so that the rail trolley 2 drives the suction mechanism 4 to align above the filling material in the front-to-back direction through the sliding trolley 3, and then stops the rail trolley 2 and starts the sliding trolley 3, so that the sliding trolley 3 drives the suction mechanism 4 to move horizontally. Aligned to the top of the filling material, the staff then stops the sliding trolley 3 and starts the vacuum pump 8, so that the vacuum pump 8 extracts the gas in the sealing cylinder 71 through the second pipe 81, and the air pressure in the sealing cylinder 71 decreases. At this time, because the ball valve head 715 is in a closed state, the sealing barrel 71 cannot extract gas to the fourth pipe 718 through the tapered through hole of the ball valve head 715, but extracts gas to the expansion and contraction pipe 651 through the first pipe 66. Similarly, the expansion and contraction pipe 651 extracts gas to the conical shell 62 through the ventilation pipe 64, and the conical shell 62 extracts gas to the storage tank through the spiral hole of the air guide ring 63 and along the air guide pipe 61. The material barrel 5 extracts gas. Since the bottom of the second electric telescopic cylinder 51 is sealed by two material blocking plates 53, the material storage barrel 5 can only extract gas to the material receiving port 42 through the first electric telescopic cylinder 41. At this time, the air pressure in the material receiving port 42 decreases, and the air pressure in the material receiving port 42 above the valve plate 44 is lower than the external air pressure below, so that the valve plate 44 is pushed upward by the external air pressure and gradually approaches the blocking bar 43. The two valve plates 44 move away from each other in the process of moving upward, so that the external gas can enter the first electric telescopic cylinder 41 from the bottom of the material receiving port 42 and form an airflow. The external gas enters the material receiving port 42 from the first electric telescopic cylinder 41. During the process of the bottom of valve 42 entering the first electric telescopic cylinder 41, the gas near the blocking bar 43 is located around the path of the airflow. According to Bernoulli's principle, the flow of the airflow causes the air pressure around the blocking bar 43 to further decrease, so that the gas around the blocking bar 43 is attracted by the airflow, and the air pressure around the blocking bar 43 continues to decrease, further causing the external air pressure to push the valve plate 44 until the valve plate 44 contacts the blocking bar 43. At this time, the staff starts the first electric telescopic cylinder 41, and the first electric telescopic cylinder 41 drives the receiving port 42 to approach the filling material until the filling material is sucked into the receiving port 42 along with the airflow.

[0030] After the filling material is sucked into the receiving port 42, it flows into the storage barrel 5 along the flow of the airflow. The filling material with larger particle size falls on the inclined blade surface of the impeller 58 due to the influence of gravity, passes through the impeller 58 and falls to the bottom of the storage barrel 5, and finally enters the second electric telescopic cylinder 51 and stays above the material blocking plate 53. The impeller 58 is driven by the impact of the filling material, so that the impeller 58 rotates and drives the elastic lever 59 to rotate synchronously. When the elastic lever 59 rotates, it slides along the inclined surface of the ratchet 57 and knocks the ratchet 57, so that the storage barrel 5 is The barrel 5 is struck to vibrate, so that the filling material attached to the inner wall of the storage barrel 5 is shaken off, and finally enters the second electric telescopic cylinder 51 along the bottom of the storage barrel 5 and stays above the material blocking plate 53. Since the air flow will be discharged to the outside along the suction direction of the vacuum fan 8, the gas in the device always maintains a low-pressure flow state, and the air flow will flow into the air guide duct 61. The filling material with smaller particle size will enter the air guide duct 61 with the air flow. In order to ensure that the air flow will not pollute the workshop environment when it is finally discharged, and in order to recover the air in the air flow, The filler in the airflow needs to be filtered and recovered. The filler with smaller particle size will enter the conical shell 62 along the spiral hole of the air guide ring 63 with the airflow. At this time, the airflow carries the filler with smaller particle size and moves spirally downward, and slides into the gap of the special-shaped thread of the conical shell 62. Since the cross-section of the special-shaped thread of the conical shell 62 is in the shape of an upper beak, the filler with smaller particle size will be guided to slide to the middle, and flow into the third pipe 67 along the bottom of the conical shell 62, and finally fall into the second electric telescopic cylinder 51. It is worth noting that the filler with tiny particle size will form an aerosol when mixed in the airflow, so that the filler with tiny particle size will flow synchronously with the airflow, and will not enter the third pipe 67 together with the filler with smaller particle size. Since the airflow is spiral under the guidance of the air guide ring 63, and the angular momentum of the airflow is conserved, after the airflow flows to the bottom of the conical shell 62, it will move upward along the special-shaped thread of the conical shell 62 in the opposite spiral direction and enter the ventilation pipe 64, completing the first filtration of the gas.

[0031] After the filler with tiny particles enters the ventilation pipe 64 with the air flow, since the filler is located in the pre-baking anode workshop, part of the filler has a high temperature when being absorbed, thereby making the air flow temperature high. In order to prevent the high temperature from damaging the subsequent filtering equipment, the air flow needs to be cooled. The air flow carries the filler with tiny particles from the ventilation pipe 64 into the expansion tube 651, and spirally rotates along the air guide thread of the expansion tube 651, thereby increasing the contact time and contact area between the air flow and the expansion tube 651, so that the heat of the air flow is transferred from the inner wall of the expansion tube 651 to the outer wall, and the heat is dissipated through the larger contact area with the outside air through the heat dissipation ring 652. The amount of heat released is as follows: as the airflow moves in the expansion and contraction tube 651, the cross-sectional area of ​​the airflow gradually increases, the airflow velocity gradually decreases, and the kinetic energy of the airflow is converted into internal energy, which is manifested macroscopically as an increase in the airflow temperature, so that more heat is transferred to the heat dissipation ring 652 through the expansion and contraction tube 651, further increasing the temperature difference between the heat dissipation ring 652 and the outside when dissipating heat, thereby improving the heat dissipation efficiency of the heat dissipation ring 652. When the airflow flows to the top of the expansion and contraction tube 651, the cross-sectional area of ​​the airflow gradually decreases, the airflow velocity gradually increases, and the internal energy of the airflow is converted into kinetic energy. Since the airflow velocity remains unchanged, the airflow is manifested macroscopically as a decrease in the airflow temperature, thereby achieving rapid cooling of the airflow.

[0032] After the airflow generated by the air extraction machine 8 is cooled by the expansion and contraction pipe 651, it carries the filler with fine particles through the first pipe 66 into the sealing cylinder 71 for further filtration. The airflow flows to the air guide cylinder 73 through the screen cloth 74, and the filler with fine particles is filtered by the screen cloth 74, so that it is adsorbed on the surface of the screen cloth 74 to achieve further filtration of the airflow. In order to avoid the screen cloth 74 being blocked by the filler with fine particles, thereby reducing the working efficiency, it is necessary to clean the filler with fine particles on the surface of the screen cloth 74 in time. When the airflow flows to the air guide cylinder 73, the cross-sectional area in the airflow direction is reduced, and the flow rate is increased, thereby blowing the fan blades 77 to rotate, and the fan blades 7 The third sliding rod 78 drives the threaded plate 75 to rotate, and the threaded plate 75 rises along the rotating thread of the support plate 76 when it rotates. Since the threaded plate 75 is connected to the screen cloth 74 in a damping rotational connection, the screen cloth 74 improves its own twisting ability by shortening its own height during the rotation and rising of the threaded plate 75. The bottom of the screen cloth 74 rotates synchronously with the threaded plate 75 under the damping restriction through the damping rotation ring. At the same time, the rotation and rising of the threaded plate 75 drives the second support frame 711 to move upward. The second support frame 711 moves upward and pushes the knocking rod 712 to rotate through the sliding column, so that the spherical surface of the knocking rod 712 is away from the screen cloth 74. When the thread of the support plate 76 is completed, When the screw plate 75 is fully inserted into the first sliding groove of the screw plate 75, the screw thread of the support plate 76 no longer supports the screw plate 75 upward, and the screw plate 75 slides downward along the support plate 76 through the first sliding groove and contacts the tray 79, so that the screw plate 75 quickly stretches and shakes the screen cloth 74 through the damping rotating ring, so that the fine-grained filler attached to the screen cloth 74 is shaken off, and the screen cloth 74 will also drive the damping rotating ring to overcome the damping and rotate during the straightening process, thereby resetting, so that the fine-grained filler on the screen cloth 74 is further separated from the screen cloth 74 by centrifugal force, and at the same time, the screw plate 75 falls and drives the second support frame 711 to reset downward, and the second support frame 711 is reset downward. 11 moves downward and pulls the knocking rod 712 through the sliding column to rotate and reset, so that the spherical surface of the knocking rod 712 knocks the screen cloth 74, causing the screen cloth 74 to further shake, thereby enhancing the shedding effect of the tiny particle size filler on the screen cloth 74. Since the conical through hole of the ball valve head 715 is in a horizontal state, the bottom of the sealing cylinder 71 is in a sealed state, and the tiny particle size filler that falls off the screen cloth 74 will fall to the bottom of the sealing cylinder 71 by gravity and be stored, thereby avoiding the tiny particle size filler from clogging the screen cloth 74 and recovering the tiny particle size filler. The airflow enters the vacuum pump 8 through the second pipe 81 and is discharged by the vacuum pump 8, thereby completing the filtering and discharge of the airflow.

[0033] After completing the absorption of the filling material, the staff turns off the vacuum pump 8, so that the air pressure in the receiving port 42 gradually increases, and the air pressure in the receiving port 42 above the valve plate 44 gradually approaches the external air pressure below it. At this time, the air pressure difference in the receiving port 42 is not enough to make the valve plate 44 contact the blocking strip 43, so that the two valve plates 44 are close to each other. Since the air flow is restricted by the valve plate 44, the cross-sectional area of ​​the air flow is reduced, resulting in little change in the air flow rate. The air flow still supports the filling material to move upward along the first electric telescopic cylinder 41, thereby preventing the filling material from spilling when the valve plate 44 is closed, until the valve plate 44 is completely contacted and closed, thereby avoiding pollution of the working environment of the pre-baked anode workshop. At the same time, since the vacuum pump 8 is turned off, the external gas entering from the bottom of the receiving port 42 will gradually enter with the air flow. The ball valve head 715 is driven by the driving motor 714 to rotate, and the large diameter end of the tapered through hole of the ball valve head 715 faces upward. The ball valve head 715 rotates, and the toggle wheel 716 is driven to rotate, so that the toggle wheel 716 squeezes the elastic knocking plate 717 and deforms it. As the deformation proceeds, the elastic knocking plate 717 gradually separates from the toggle wheel 716. When the elastic knocking plate 717 separates from the toggle wheel 716, the elastic knocking plate 717 releases its elastic force and knocks the toggle wheel 716 again. The toggle wheel 716 is subjected to the knocking vibration and is transmitted to the ball valve head 715, so that when the ball valve head 715 is attached with filler with fine particle size, it will be vibrated and fall off, thereby realizing the preliminary cleaning of the ball valve head 715.

[0034] After the filling material is absorbed, it is necessary to place the filling material at the designated position. At this time, the filling material in the storage cylinder 5 enters the second electric telescopic cylinder 51 by gravity, and the fine-grained filling material in the sealing cylinder 71 enters the conical through hole of the ball valve head 715 through the valve housing 713, and enters the second electric telescopic cylinder 51 along the fourth pipe 718. The filling material in the second electric telescopic cylinder 51 will fall on the material blocking plate 53. In the process of the fine-grained filling material in the sealing cylinder 71 entering the conical through hole of the ball valve head 715 through the valve housing 713, it will contact the inclined surface of the conical through hole, thereby scratching the inclined surface of the conical through hole, further cleaning the fine-grained filling material attached to the conical through hole. Fig.12As shown, after the filling material enters the second electric telescopic cylinder 51, the staff starts the double-headed motor 56, the output shaft of the double-headed motor 56 is connected clockwise, and because the two material blocking plates 53 are in contact with each other and are subjected to the pressure of the filling material, the first connecting rod 54 is controlled by the second connecting rod 55 to drive the material blocking plate 53 to rotate clockwise under the extrusion of the limit groove and move upward at the same time. At this time, the material blocking plate 53 in the second electric telescopic cylinder 51 becomes shorter, and the filling material falls from between the two material blocking plates 53 and falls to the specified position. At this time, the double-headed motor 56 is stopped and the filling material is placed. After the filling material is placed, the staff starts the double-headed motor 56 to reverse, so that the output shaft rotates counterclockwise through the first connecting rod 54 to drive the material blocking plate 53 to reset, so that the material blocking plate 53 is inserted into the second electric telescopic cylinder 51. Since the moving direction of the material blocking plate 53 is the same as that of the filling material The moving directions of the materials are similar, so the filling material poses little obstacle to the movement of the material blocking plate 53. When the two material blocking plates 53 contact each other, the double-headed motor 56 is stopped to complete the placement of the filling material. If the staff needs to scrape the upper surface of the filling material flat, the staff starts the second electric telescopic cylinder 51 at this time, and the bottom end of the second electric telescopic cylinder 51 drives the discharge port 52 to reach the height to be scraped flat, and the rail trolley 2 is started to slide on the rail beam 1, so that the rail trolley 2 drives the storage barrel 5 to move through the sliding trolley 3, and the storage barrel 5 moves through the second electric telescopic cylinder 51 to drive the discharge port 52 to move, so that the bottom of the discharge port 52 scrapes the upper surface of the filling material, and the sliding trolley 3 is started, so that the storage barrel 5 drives the discharge port 52 to move through the second electric telescopic cylinder 51, thereby adjusting the scraped position of the discharge port 52, and realizing the scraping of the upper surface of the filling material at different positions.

[0035] After the roasting process of the filler is completed in the pre-baked anode workshop, carbon blocks will be obtained. At this time, the carbon blocks need to be transported to other locations for later transportation. At this time, the staff starts the rail trolley 2 and the sliding trolley 3, so that the rail trolley 2 and the sliding trolley 3 drive the mounting platform 9 to move synchronously through the columns, so that the telescopic clamping mechanism 10 is located above the carbon block, and the staff starts the electric telescopic rod 101 to move the bottom of the electric telescopic rod 101 downward. The movement of the bottom of the electric telescopic rod 101 drives the sliding block 103 to move downward through the cross-hinged connecting rod group 102. The movement of the sliding block 103 drives the clamping plate 1071 to move downward. The clamping plate 1071 moves to contact the top of the carbon block. The two clamping plates 1071 are squeezed by the carbon block, thereby passing through the clamping plate 107 1 makes the sliding block 103 stationary in the vertical direction, the electric telescopic rod 101 continues to move downward so that the cross-hinged connecting rod group 102 is forced to push the sliding blocks 103 away from each other, and the clamping plates 1071 are driven to move away from each other and away from the top of the carbon block through the threaded cylinder 106, so that the two clamping plates 1071 are located on both sides of the carbon block. At this time, the overall height of the cross-hinged connecting rod group 102 becomes smaller and the overall width becomes larger. The bottom of the electric telescopic rod 101 continues to move, so that the sliding block 103 drives the positioning shell 1081 to move through the first sliding rod 104, so that the extruding threaded column 1084 squeezes the top of the carbon block. The carbon block does not move so that the extruding threaded column 1084 remains stationary, and the positioning shell 1081 moves downward so that the extruding threaded column 1084 drives the worm 1083 to rotate The worm 1083 rotates through the worm wheel 1082 to drive the second sliding rod 105 to rotate. The second sliding rod 105 rotates through the threaded cylinder 106 to drive the clamping plates 1071 to approach each other. The clamping plates 1071 approach each other and drive the second clamping block 1073 to approach each other through the first clamping block 1072, so that the second clamping block 1073 contacts the carbon block. Then the positioning housing 1081 continues to move downward. Since the second clamping block 1073 has contacted the carbon block and remains stationary, the second clamping block 1073 keeps the clamping plate 1071 stationary through the reset spring. Therefore, the positioning housing 1081 continues to move downward and does not drive the second clamping block 1073 to further squeeze the carbon block, but drives the second sliding rod 105 to rotate and drives the sliding block through the threaded cylinder 106. 103 move away from each other, indicating that the second clamping block 1073 has clamped the carbon block. At this time, the staff can clamp and carry the carbon block. Compared with the servo motor driven clamping claws that clamp the carbon block in the prior art, the second clamping block 1073 remains motionless after contacting the carbon block, and the sliding blocks 103 move away from each other, which is convenient for the staff to identify the clamped state of the carbon block, avoiding the problem that the clamping state of the carbon block is difficult to distinguish, greatly improving the operational tolerance of the carbon block clamping, and improving the efficiency of the carbon block clamping. Then the staff starts the electric telescopic rod 101, so that the electric telescopic rod 101 drives the top of the cross-hinged connecting rod group 102 to move upward and reduce the overall width. The overall width of the cross-hinged connecting rod group 102 is reduced, thereby driving the clamping plates 1071 to move closer to each other.The clamping plates 1071 are close to each other so that the two adjacent first clamping blocks 1072 are away from each other. At the same time, the clamping plate 1071 is close to the second clamping block 1073 to squeeze the reset spring. Since the two ends of the reset spring are subjected to the same force, the second clamping block 1073 always maintains a stable clamping force. If the pressure generated by the reduction in the overall width of the cross-hinged connecting rod group 102 causes the first clamping block 1072 to contact the carbon block, the area of ​​the carbon block clamped increases, and the pressure per unit area becomes smaller, thereby preventing the carbon block from being broken due to internal strength defects of the carbon block. When the overall width of the cross-hinged connecting rod group 102 no longer decreases, the cross-hinged connecting rod group 102 drives the clamping plate 1071 to move upward through the sliding block 103, and the clamping plate 1071 moves through the first clamping block 1072 to control the second clamping block 1073 to drive the carbon block to move upward, thereby realizing the transportation of the carbon block. Subsequently, the staff starts the track trolley 2 and the sliding trolley 3, so that the sliding trolley 3 controls the movement of the installation platform 9 through the column, thereby extending the extension The retractable clamping mechanism 10 adjusts the placement position of the charcoal block. After the charcoal block is positioned, the staff starts the electric telescopic rod 101, thereby repeating the process of squeezing the threaded column 1084 and squeezing the worm 1083 to rotate, so that the clamping plates 1071 move away from each other, and the reset spring is not subjected to the large pressure of the clamping plate 1071 and restores its shape, and the clamping force of the second clamping block 1073 on the charcoal block becomes smaller. At this time, the staff starts the rail trolley 2, so that the rail trolley 2 controls the column through the sliding trolley 3 to drive the installation platform 9 to move, thereby making the telescopic clamping mechanism 10 slide away from the charcoal block. Under the action of gravity, the cross-hinged connecting rod group 102 resets itself, and the squeezing threaded column 1084 moves downward to drive the worm 1083 to drive the worm wheel 1082 to rotate, so that the second sliding rod 105 rotates through the threaded cylinder 106 to drive the clamping plate 1071 to reset relative to the sliding block 103. Finally, the staff starts the electric telescopic rod 101 to retract it, completing the resetting of the telescopic clamping mechanism 10 and completing the entire charcoal block handling operation.
