Abstract

This invention belongs to the field of overhead crane technology and discloses a special clamping overhead crane for graphitization, including a car body. A control frame is fixedly installed inside the car body, and a lifting rod is fixedly installed on the bottom surface of the control frame. A clamping frame is fixedly connected to the bottom surface of the lifting rod. This invention utilizes a pumping mechanism to introduce pressurized oil into each set of connecting sleeves via a distribution sleeve. The continuously introduced pressurized oil pushes two sets of push rods on the side of the elastic plate, causing the elastic plate to bend and deform. This bending deformation allows for full contact and compression with the surface of the graphite crucible, increasing the contact area during clamping and significantly increasing friction. Furthermore, by coordinating sufficient oil pressure into the inner cavity of the elastic plate, local expansion of the elastic plate further increases the arc-shaped contact area between the elastic plate and the graphite crucible. By expanding the clamping area and increasing friction, the stability of the actual clamping and stacking is greatly improved.

Description

Technical Field

[0001] This invention belongs to the field of overhead crane unit technology, specifically a graphitized special clamp overhead crane. Background Technology

[0002] Graphite crucibles, also known as copper melting pots or copper melting pots, are a type of crucible made from graphite, clay, silica, and pyroxene. Using natural flake graphite as the main raw material and plastic refractory clay or carbonaceous material as a binder, graphite crucibles are characterized by high temperature resistance, strong thermal conductivity, good corrosion resistance, and long service life. The smooth inner wall of a graphite crucible prevents molten metal from leaking or adhering to the inner wall, giving the molten metal good fluidity and castability. They are suitable for casting in various molds. When stacking graphite crucibles, overhead cranes are typically used.

[0003] In existing graphite crucible stacking cranes, multiple sets of graphite crucibles placed below are typically clamped together during the stacking process, and then hoisted to the graphite crucible storage area. For stacking large quantities of graphite crucibles, the current method of clamping with side clamps is used. However, due to the smooth surface of the graphite crucibles, and the fact that the actual surface of the graphite crucibles is curved, the clamping area of ​​the current clamps is small, resulting in low friction during the actual clamping process. Under abnormal conditions such as vibration, the graphite crucibles are prone to falling off, causing economic losses, and the actual clamping stability is poor.

[0004] Furthermore, in the existing graphite crucible stacking crane units, during operation, multiple sets of graphite crucibles are typically placed together to improve clamping efficiency before being clamped. However, during stacking, distance errors during placement cause misalignment between the graphite crucibles, resulting in poor placement stability. Manual fine-tuning is usually required, which significantly increases stacking time, reduces stacking efficiency, and leads to unsatisfactory performance. Summary of the Invention

[0005] The purpose of this invention is to provide a graphitization-specific clamp crane to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a graphitization-specific clamp crane, comprising a car body, a control frame fixedly installed inside the car body, a lifting rod fixedly installed on the bottom surface of the control frame, a clamping frame fixedly connected to the bottom surface of the lifting rod, a partition plate fixedly connected to the inner surface of the clamping frame, a distribution sleeve fixedly installed on the side of the clamping frame, a fixing plate fixedly connected to the bottom surface of the distribution sleeve, a telescopic rod fixedly connected to the side of the fixing plate, an intermediate plate fixedly connected to the inner end of the telescopic rod, an elastic plate fixedly connected to the side of the intermediate plate, a push rod fixedly connected to the side of the elastic plate, a movable plug fixedly connected to the outer end face of the push rod, a sleeve movably sleeved on the outer surface of the movable plug and the push rod, a connecting sleeve fixedly connected to the end face of the sleeve, a No. 1 pipe fixedly connected between the connecting sleeve and the distribution sleeve, a curved pipe fixedly connected between the elastic plate and the push rod, an inner cavity opened inside the elastic plate, a curved hole opened inside the push rod, and an oil pumping mechanism provided on the top surface of the distribution sleeve.

[0007] First embodiment: as follows Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and 7 As shown, when clamping the graphite crucible, the lifting rod lowers the clamping frame along the placement position of the graphite crucible, so that the graphite crucible is located inside the clamping frame. The telescopic rod moves and pushes the elastic plate to move and contact the graphite crucible. At this time, the graphite crucible and the elastic plate are in line contact. The oil pumping mechanism is activated, so that the oil pumping mechanism draws pressure oil from the oil tank and delivers the pressure oil to the distribution sleeve. As the pressure oil in the distribution sleeve enters the connecting sleeve through the No. 1 pipe, it is split into the sleeves on both sides through the connecting sleeve. The pressure oil in the sleeve pushes the movable plug and push rod to move, which in turn causes the push rods on both sides to push the elastic plate to deform. This causes the elastic plate to bend on both sides and fit against the surface of the graphite crucible. At the same time, as pressure oil continues to be supplied, some pressure oil flows through the curved hole in the push rod to the curved tube, and through the curved tube, some pressure oil is introduced into the inner cavity of the elastic plate. This causes the middle part of the elastic plate to expand and contact the arc-shaped surface of the graphite crucible, completing the wrapping and clamping of the side of the graphite crucible.

[0008] First, by adding a telescopic rod to the side of the clamping frame, the telescopic rod drives the elastic plate to make line contact with the surface of the graphite crucible. After contact and compression, pressurized oil is introduced into each set of connecting sleeves through the pumping mechanism. The continuously introduced pressurized oil pushes two sets of push rods on the side of the elastic plate to move, thereby causing the elastic plate to bend and deform. During bending and deformation, the plate fully contacts and compresses the surface of the graphite crucible, thus increasing the contact surface when clamping the graphite crucible and greatly increasing the friction. Furthermore, by introducing sufficient oil pressure into the inner cavity of the elastic plate, the elastic plate expands locally, further increasing the arc surface contact area between the elastic plate and the graphite crucible. By expanding the clamping area and increasing the friction, the stability of the actual clamping and stacking is greatly improved.

[0009] Furthermore, by using a telescopic rod to push the elastic plate to move and contact the surface of the graphite crucible, and then using pressurized oil to push the two sets of push rods on the side of the elastic plate to move, the elastic plate bends on both sides to adapt to the surface curvature of the graphite crucible and achieve good contact. For graphite crucibles of different diameters, the elastic plate of sufficient length can be bent and deformed to fit the surface of the graphite crucible, which improves the clamping adaptability of graphite crucibles of different sizes and specifications. It can easily achieve the clamping and stacking of graphite crucibles of different specifications without the need to change the clamping components, making it convenient to use.

[0010] Preferably, the oil pumping mechanism includes an oil pump, a second pipe, and a third pipe. The oil pump is fixedly installed on the top surface of the distribution sleeve. The second pipe is fixedly connected between the oil pump and the distribution sleeve. The third pipe is fixedly connected to the top surface of the oil pump. The pressure oil in the oil tank is drawn from the third pipe of the oil pumping mechanism and pumped to the distribution sleeve by the second pipe. The distribution sleeve effectively distributes the pressure oil to each group of first pipes.

[0011] Preferably, an oil tank is fixedly installed on the top surface of the clamping frame, and the side of the oil tank is fixedly connected to the No. 3 pipe. By using an oil pumping mechanism to draw pressurized oil from the oil tank, sufficient oil pressure is ensured to drive the elastic plate to deform and expand.

[0012] Preferably, the diameter of the movable plug is smaller than the inner diameter of the sleeve, the diameter of the movable plug is larger than the diameter of the push rod, and the upper end of the curved hole passes through the movable plug. By controlling the diameter of the movable plug and the diameter of the push rod, when the pressure oil in the sleeve pushes the movable plug and the push rod to move, pressure oil leakage is avoided, thus achieving a certain sealing effect.

[0013] Preferably, a sleeve plate is fixedly fitted onto the inner surface of the inner cavity. The sleeve plate is located in the middle of the inner cavity, and the curved tube is connected to the inner cavity. By using the sleeve plate to enhance the contact pressure in the middle of the elastic plate, the deformation distance in the middle of the elastic plate is avoided, and the pressure of the side clamping is sufficient.

[0014] Preferably, the top surface of the partition is provided with a top groove, the side surface of the partition is provided with an installation port, and the interior of the partition is provided with a through hole. The upper and lower ends of the through hole are respectively connected to the top groove and the installation port. By utilizing the connection of the through hole, it is convenient to introduce the air supplied from the ventilation plate into each group of airbags.

[0015] Preferably, an airbag is fixedly installed inside the mounting port. The top of the airbag is connected to the through hole. By utilizing the airbag to expand, the volume of space is increased, and the graphite crucible placed on both sides is pushed to move and center. The outer surface of the airbag is partially fixedly connected to the mounting port to ensure that the airbag has sufficient deformation space.

[0016] Preferably, a vent plate is fixedly installed on the top surface of the inner surface of the clamping frame. The vent plate is located inside the top groove. A pumping mechanism is fixedly installed on the side of one of the partitions. By utilizing the vent plate and the through holes, the introduced air can be quickly delivered to each group of airbags to achieve ventilation distribution.

[0017] Preferably, the air pumping mechanism includes a mounting plate, an air pump, and a connecting pipe. The mounting plate is fixedly connected to the outer side of the partition, the air pump is fixedly installed on the top surface of the mounting plate, one end of the connecting pipe is fixedly connected to the top surface of the air pump, and the other end of the connecting pipe is fixedly connected to the vent plate. Air is input into the vent plate through the connecting pipe by using the air pumping mechanism. The specific air pumping mechanism is located on the side of the outermost partition.

[0018] Preferably, the clamping frame has side grooves on its side, the number of which is the same as the number of elastic plates. The side grooves and elastic plates are linearly and equally spaced, ensuring that each group of graphite crucibles has a symmetrical clamping effect.

[0019] Second embodiment: as follows Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, before clamping the graphite crucible on the side, when the clamping frame covers the outside of the graphite crucible, the air pumping mechanism is activated. As the air pumping mechanism supplies air to the venting plate through the connecting pipe, a large amount of air flows through the venting plate to each set of through holes, and then the air enters the air bladders through the through holes, causing each set of air bladders to inflate simultaneously. As the air bladders on both sides of the graphite crucible gradually expand, they push the graphite crucible from both sides simultaneously, causing the graphite crucible that has shifted position to be gradually moved to the center position by the thrust, so that each set of graphite crucibles maintains the same lateral spacing. Then, the telescopic rod is activated, so that the elastic plates on the front and rear sides push the graphite crucible from the front and rear sides simultaneously, so that the position of the graphite crucible is corrected, ensuring that the front and rear positions of each set of graphite crucibles are consistent. The air pumping mechanism is then turned off and stable clamping is performed.

[0020] First, by insulating airbags inside each set of partitions and connecting each set of elastic airbags through through holes and ventilation plates in the partitions, the airbags on both sides of the graphite crucible expand simultaneously under the pumping effect of the pumping mechanism. The expanding airbags on both sides gradually push the offset graphite crucible to move and center it. Combined with the pushing of the elastic plates on the front and rear sides during clamping, each set of graphite crucibles maintains the same spacing. When stacking, this ensures that the graphite crucibles placed vertically have a good alignment effect, avoids offset affecting the stacking stability of the graphite crucibles, and has a good performance.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. This invention adds a telescopic rod to the side of the clamping frame, causing the telescopic rod to drive the elastic plate into line contact with the surface of the graphite crucible. After contact and compression, pressurized oil is introduced into each set of connecting sleeves via a pumping mechanism. The continuously introduced pressurized oil pushes two sets of push rods on the side of the elastic plate to move, causing the elastic plate to bend and deform. During bending and deformation, the plate fully contacts and compresses the surface of the graphite crucible, thereby increasing the contact area when clamping the graphite crucible and greatly increasing the friction. Furthermore, by introducing sufficient oil pressure into the inner cavity of the elastic plate, the elastic plate expands locally, further increasing the arc surface contact area between the elastic plate and the graphite crucible. By expanding the clamping area and increasing the friction, the stability of the actual clamping and stacking is greatly improved.

[0023] 2. This invention utilizes a telescopic rod to move an elastic plate and bring it into contact with the surface of a graphite crucible. After contact, pressure oil is used to move two sets of push rods on the side of the elastic plate, causing the elastic plate to bend on both sides, thereby adapting to the surface curvature of the graphite crucible and achieving good contact. For graphite crucibles of different diameters, it ensures that the elastic plate of sufficient length can bend and deform to fit the surface of the graphite crucible, improving the clamping adaptability to graphite crucibles of different sizes. It can easily achieve the clamping and stacking of graphite crucibles of different specifications without the need to change the clamping components, making it convenient to use.

[0024] 3. This invention incorporates airbags inside each set of partitions, connecting them via through holes and ventilation plates. The pumping mechanism causes the airbags on both sides of the graphite crucible to expand simultaneously and in unison. The expanding airbags gradually push the offset graphite crucible towards centering. Combined with the pushing action of the elastic plates on both sides during clamping, this ensures that each set of graphite crucibles maintains the same spacing. During stacking, this guarantees good alignment of the graphite crucibles placed vertically, preventing offset from affecting the stacking stability and resulting in excellent performance.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 9As shown, this embodiment of the invention provides a graphitization-specific clamp crane, including a car body 1. A control frame 2 is fixedly installed inside the car body 1. A lifting rod 3 is fixedly installed on the bottom surface of the control frame 2. A clamping frame 4 is fixedly connected to the bottom surface of the lifting rod 3. A partition plate 5 is fixedly connected to the inner surface of the clamping frame 4. A distribution sleeve 6 is fixedly installed on the side of the clamping frame 4. A fixing plate 7 is fixedly connected to the bottom surface of the distribution sleeve 6. A telescopic rod 8 is fixedly connected to the side of the fixing plate 7. An intermediate plate 9 is fixedly connected to the inner end of the telescopic rod 8. An elastic plate 10 is fixedly connected to the side of the intermediate plate 9. A push rod 11 is fixedly connected to the side of the elastic plate 10. The push rods 11 on both sides push the elastic plate 10 to bend on both sides, causing the elastic plate 10 to bend on both sides. The side and curved surface bring the graphite crucible into contact, thereby expanding the contact area, increasing friction, and improving the stability of the clamping and stacking. A movable plug 12 is fixedly connected to the outer end face of the push rod 11. A sleeve 13 is movably sleeved on the outer surface of the movable plug 12 and the push rod 11. A connecting sleeve 14 is fixedly connected to the end face of the sleeve 13. A tube 15 is fixedly connected between the connecting sleeve 14 and the distribution sleeve 6. A curved tube 16 is fixedly connected between the elastic plate 10 and the push rod 11. An inner cavity 19 is opened inside the elastic plate 10. A curved hole 21 is opened inside the push rod 11. An oil pumping mechanism 17 is provided on the top surface of the distribution sleeve 6. By using the pressure oil entering the elastic plate 10, the elastic plate 10 is locally expanded, further increasing the contact area.

[0037] First embodiment: as follows Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and 7 As shown, when it is necessary to clamp the graphite crucible, the lifting rod 3 lowers the clamping frame 4 along the placement position of the graphite crucible, so that the graphite crucible is located inside the clamping frame 4. The telescopic rod 8 moves and pushes the elastic plate 10 to move and contact the graphite crucible. At this time, the graphite crucible and the elastic plate 10 are in line contact. The oil pumping mechanism 17 is activated, so that the oil pumping mechanism 17 draws pressure oil from the oil tank 18 and delivers the pressure oil to the distribution sleeve 6. As the pressure oil in the distribution sleeve 6 enters the connecting sleeve 14 through the first pipe 15, it is then split into two streams on the left and right sides of the connecting sleeve 14. In the sleeve 13 on the side, the pressure oil in the sleeve 13 pushes the movable plug 12 and push rod 11 to move, which in turn causes the push rods 11 on both sides to push the elastic plate 10 to deform, so that the elastic plate 10 bends on both sides and fits against the surface of the graphite crucible. At the same time, as the pressure oil continues to be supplied, some pressure oil flows through the curved hole 21 in the push rod 11 to the curved tube 16, and through the curved tube 16, some pressure oil is introduced into the inner cavity 19 of the elastic plate 10, so that the middle part of the elastic plate 10 expands and contacts the arc-shaped surface of the graphite crucible, thus completing the wrapping and clamping of the side of the graphite crucible.

[0038] First, by adding a telescopic rod 8 to the side of the clamping frame 4, the telescopic rod 8 causes the elastic plate 10 to make line contact with the surface of the graphite crucible. After contact and compression, pressurized oil is introduced into each set of connecting sleeves 14 through the distribution sleeve 6 by the oil pump mechanism 17. The continuously introduced pressurized oil pushes the two sets of push rods 11 on the side of the elastic plate 10 to move, thereby causing the elastic plate 10 to bend and deform. During bending and deformation, it makes full contact and compression with the surface of the graphite crucible, thereby increasing the contact surface when clamping the graphite crucible and greatly increasing the friction. In addition, by introducing sufficient oil pressure into the inner cavity 19 of the elastic plate 10, the elastic plate 10 expands locally, further increasing the arc contact area between the elastic plate 10 and the graphite crucible. By expanding the clamping area and increasing the friction, the stability of the actual clamping and stacking is greatly improved.

[0039] Furthermore, by using the telescopic rod 8 to push the elastic plate 10 to move and contact the surface of the graphite crucible, and then using pressurized oil to push the two sets of push rods 11 on the side of the elastic plate 10 to move, the elastic plate 10 bends on both sides to adapt to the surface curvature of the graphite crucible and achieve good contact. For graphite crucibles of different diameters, the elastic plate 10 of sufficient length can be bent and deformed to fit the surface of the graphite crucible, which improves the clamping adaptability to graphite crucibles of different sizes and specifications. It can easily achieve the clamping and stacking of graphite crucibles of different specifications without the need to change the clamping components, making it convenient to use.

[0040] The oil pumping mechanism 17 includes an oil pump 171, a second pipe 172, and a third pipe 173. The oil pump 171 is fixedly installed on the top surface of the distribution sleeve 6. The second pipe 172 is fixedly connected between the oil pump 171 and the distribution sleeve 6. The third pipe 173 is fixedly connected to the top surface of the oil pump 171. The pressure oil in the oil tank 18 is drawn by the third pipe 173 in the oil pumping mechanism 17 and pumped to the distribution sleeve 6 by the second pipe 172. The pressure oil is effectively distributed to each group of first pipes 15 by the distribution sleeve 6.

[0041] The top surface of the clamping frame 4 is fixedly equipped with an oil tank 18, and the side of the oil tank 18 is fixedly connected to the No. 3 pipe 173. By using the oil pumping mechanism 17 to draw pressure oil from the oil tank 18, sufficient oil pressure is ensured to push the elastic plate 10 to deform and expand.

[0042] The diameter of the movable plug 12 is smaller than the inner diameter of the sleeve 13, and the diameter of the movable plug 12 is larger than the diameter of the push rod 11. The upper end of the curved hole 21 passes through the movable plug 12. By controlling the diameter of the movable plug 12 and the diameter of the push rod 11, when the pressure oil in the sleeve 13 pushes the movable plug 12 and the push rod 11 to move, pressure oil leakage is avoided, and a certain sealing effect is achieved.

[0043] The inner surface of the inner cavity 19 is fixedly fitted with a sleeve plate 20, which is located in the middle of the inner cavity 19. The curved tube 16 is connected to the inner cavity 19. By using the sleeve plate 20 to enhance the contact pressure in the middle of the elastic plate 10, the deformation distance in the middle of the elastic plate 10 is avoided, and the pressure of the side clamping is sufficient.

[0044] The partition 5 has a top groove 24 on its top surface, an installation port 22 on its side, and a through hole 25 inside. The upper and lower ends of the through hole 25 are connected to the top groove 24 and the installation port 22, respectively. By utilizing the connection of the through hole 25, it is convenient to introduce the air supplied from the vent plate 26 into each airbag 23.

[0045] An airbag 23 is fixedly installed inside the mounting port 22. The top of the airbag 23 is connected to the through hole 25. By utilizing the airbag 23 to expand, the volume of space is increased, and the graphite crucible placed on both sides is pushed to move and center. The outer surface of the airbag 23 is partially fixedly connected to the mounting port 22 to ensure that the airbag 23 has sufficient deformation space.

[0046] A ventilation plate 26 is fixedly installed on the top surface of the inner surface of the clamping frame 4. The ventilation plate 26 is located inside the top groove 24. A pumping mechanism 27 is fixedly installed on the side of a partition 5. By utilizing the ventilation plate 26 and the through hole 25, the air introduced can be quickly delivered to each group of airbags 23 to achieve ventilation distribution.

[0047] The air pumping mechanism 27 includes a mounting plate 271, an air pump 272, and a connecting pipe 273. The mounting plate 271 is fixedly connected to the outer side of the partition 5. The air pump 272 is fixedly installed on the top surface of the mounting plate 271. One end of the connecting pipe 273 is fixedly connected to the top surface of the air pump 272, and the other end of the connecting pipe 273 is fixedly connected to the vent plate 26. Air is input into the vent plate 26 through the connecting pipe 273 by using the air pumping mechanism 27. Specifically, the air pumping mechanism 27 is located on the side of the outermost partition 5.

[0048] The clamping frame 4 has side grooves 28 on its side. The number of side grooves 28 is the same as the number of elastic plates 10. The side grooves 28 and elastic plates 10 are linearly and equally spaced. By making the side grooves 28 and elastic plates 10 linearly and equally spaced, each group of graphite crucibles has a symmetrical clamping effect.

[0049] Second embodiment: as follows Figure 1 , Figure 2 , Figure 3 and Figure 9As shown, before clamping the graphite crucible on the side, when the clamping frame 4 covers the outside of the graphite crucible, the air pumping mechanism 27 is activated. As the air pumping mechanism 27 circulates air through the connecting pipe 273 to the venting plate 26, a large amount of air flows through the venting plate 26 to each set of through holes 25, and then the air enters the airbags 23 through the through holes 25, causing each set of airbags 23 to inflate simultaneously. As the airbags 23 on both sides of the graphite crucible gradually expand, they push the graphite crucible from both sides simultaneously, causing the graphite crucible that has shifted position to be gradually moved to the center position by the pushing force, so that each set of graphite crucibles maintains the same lateral spacing. Then, the telescopic rod 8 is activated, so that the elastic plates 10 on the front and rear sides push the graphite crucible from the front and rear sides simultaneously, so that the position of the graphite crucible is corrected, ensuring that the front and rear positions of each set of graphite crucibles are horizontally consistent. The air pumping mechanism 27 is then turned off and stable clamping is performed.

[0050] First, by installing airbags 23 inside each set of partitions 5 and connecting each set of elastic airbags 23 through through holes and ventilation plates 26 in the partitions 5, the airbags 23 on both sides of the graphite crucible expand simultaneously and in the same way under the pumping effect of the pumping mechanism 27. The expanded airbags on both sides gradually push the offset graphite crucible to move and center. Combined with the pushing of the elastic plates 10 on the front and rear sides during clamping, each set of graphite crucibles maintains the same spacing. When stacking, this ensures that the graphite crucibles placed on top and bottom have a good alignment effect, avoids offset affecting the stacking stability of the graphite crucibles, and has a good performance.
