Description

Technical Field

[0001] The invention relates to the technical field of reactor transportation equipment, in particular to a hoisting machine for transferring a large glass-lined reactor. Background Art

[0002] Glass-lined reactors are large pressure vessels commonly used in the chemical, pharmaceutical, and food industries. They feature strong corrosion resistance and excellent sealing properties, making them widely used in the stirring, mixing, and reaction processes of various materials. During equipment installation, maintenance, or transportation, these reactors often require hoisting. However, existing hoisting methods often rely on manual operation combined with lifting machinery, resulting in poor hoisting accuracy and low positioning efficiency. Furthermore, the reactors are prone to bumps or scratches during the gripping process. Traditional clamping structures, in particular, struggle to achieve universal clamping for large reactors of various specifications and weights, posing safety risks and efficiency bottlenecks.

[0003] Furthermore, most existing lifting equipment lacks the ability to detect and adjust according to the state of the hoisted object. It cannot automatically adjust the clamping force according to different weights, which can easily lead to problems such as loose clamping or damage due to overpressure. This seriously restricts the safe lifting and intelligent development of large chemical equipment.

[0004] In summary, there is an urgent need for a lifting device with stable structure, flexible clamping, controllable movement, safe linkage and intelligent adjustment capabilities to meet the safe and efficient transportation needs of equipment such as large glass-lined reactors.

[0005] After searching, the invention patent with the prior art publication number CN116812732A discloses a lifting mechanism for transferring a large glass-lined reactor and a method for using the same, including a reactor body and a connecting piece. The lifting mechanism includes: a lifting assembly, which is used to lift the glass-lined reactor more conveniently; a buffer assembly, which is used to provide buffering when lowering the glass-lined reactor; the scheme starts by starting a first electric push rod to drive the movable ring downward and move it to the bottom of the lifting base, leaving a gap between the movable ring and the lifting piece for inserting a card block, and a first spring supports the moving rod and the card block to extend out of the moving groove, and the card block moves into the lifting groove, and the lifting piece is clamped by the card block to fix the lifting shell and the lifting ear. When transferring the reactor, the lifting shell can be connected to the reactor body more conveniently and quickly, making the installation of the lifting mechanism more convenient, shortening the time for installing the lifting mechanism, and improving the lifting efficiency.

[0006] Therefore, based on the above search and in combination with the existing technology, a large glass-lined reactor is currently used for hoisting and fixing using a lifting mechanism and a method for using the same. The device mainly relies on mechanical plug-in between the clamping block, the hoisting slot and the lifting ear to achieve hoisting and fixation. This method has high requirements on the contact size tolerance and cannot adapt to the reactor body of different sizes or deformations. At the same time, it does not provide a perception and feedback mechanism for load changes, air pressure control or clamping force during the hoisting process. There is a safety hazard that the clamping force is too large to cause damage to the equipment, or too small to cause it to fall off. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example 1, please refer to Figures 1 to 9A large glass-lined reactor transfer hoist includes a hoisting assembly 1, which includes two sliding rails 11. Specifically, the left and right ends of the two sliding rails 11 are welded with steel frames 112. The bottom ends of the two steel frames 112 are installed with first moving vehicles 113.

An internal threaded sleeve is welded and fixed to the bottom surface of the first moving vehicle 113. The internal threaded sleeve is threadedly connected to the screw 13 Then, the screw 13 is driven to rotate by the stepping motor 14, and the screw 13 drives the first moving car 113 to move linearly in the sliding box 12, indirectly driving the sliding rail 11 to move, and the outer walls of the two sliding rails 11 are slidingly connected with a transverse moving component 2, and the transverse moving component 2 includes an electric hoist 23, and the electric hoist 23 is connected to a hook 25 through a steel chain 24. The hook 25 is fixedly installed with a detection component 3, and a clamping component 4 is fixedly installed at the bottom end of the detection component 3. The clamping component 4 is used to clamp and fix the reactor body 5, and the clamping component 4 includes an airtight ring 41. Several groups of trigger components 6 are equidistantly installed on the outer wall of the airtight ring 41, and several safety components 7 are equidistantly installed on the outer wall of the airtight ring 41. Specifically, several safety components 7 and several trigger components 6 are staggered to avoid interference.

[0045] The lateral moving assembly 2 also includes a second moving car 21, which is connected to the sliding rail 11 through moving wheels, and the moving wheels are driven by a DC motor 22. A slewing boom assembly is installed on the bottom of the second moving car 21, and the slewing boom assembly can rotate around the vertical axis at the top of the beam. Specifically, the slewing boom assembly is driven by a slewing motor, the slewing motor model is MHMF012L1V2M, and the DC motor 22 model is CCL36070C1-1000M-24-6-GS. The DC motor 22 drives the second moving car 21 to move left and right on the outer wall of the sliding rail 11, indirectly driving the slewing boom assembly and the electric hoist 23 to move left and right. The electric hoist 23 drives the reactor body 5 to move synchronously through the steel chain 24 and the hook 25. The electric hoist 23 is mounted on the bottom end of the slewing boom assembly, and the lifting range of the electric hoist 23 is expanded through the movement of the slewing boom assembly.

[0046] Example 2, please refer to Figures 3 to 6, a large glass-lined reactor transfer hoist, which is different from Example 1 in that the detection component 3 includes a mounting cylinder 31, a first piston 32 is slidably connected to the mounting cylinder 31, a connection detection rod 321 is welded and fixed at the center of the top surface of the first piston 32, the top of the connection detection rod 321 passes through the top wall of the mounting cylinder 31 and is fixedly connected to the hook 25, a first spring 33 is sleeved on the outer wall of the connection detection rod 321, the bottom end of the first spring 33 abuts against the top surface of the first piston 32, the top end of the first spring 33 abuts against the inner top surface of the mounting cylinder 31, and a sliding rheostat 34 is fixedly installed on the outer wall of the mounting cylinder 31, which has The mounting cylinder 31 is provided with an extension plate 311 on the top surface thereof, and the sliding rheostat 34 is fixedly mounted on the end of the extension plate 311 by bolts. A slide groove is provided on the outer wall of the mounting cylinder 31, and an extension rod is welded to the outer wall of the first piston 32. The first piston 32 is fixedly connected to the rheostat needle of the sliding rheostat 34 through the extension rod through the slide groove. Specifically, the first spring 33 can detect the weight of the reactor body 5. According to the weight of the reactor body 5, the first spring 33 is compressed to a certain extent, and the first piston 32 drives the rheostat needle of the sliding rheostat 34 to move through the extension rod, thereby changing the resistance value of the sliding rheostat 34.

[0047] Example 3, please refer to Figures 6 to 13, a large glass-lined reactor transfer hoist, which is different from Example 1 in that a mounting plate 411 is welded and fixed to the top surface of the airtight ring 41, and the top surface of the mounting plate 411 is fixedly connected to the bottom surface of the mounting cylinder 31 by bolts, and a mounting seat 412 is welded and fixed to the outer wall of the airtight ring 41, and an air pump body 42 is fixedly installed on the top surface of the mounting seat 412 by bolts. Specifically, the air pump body 42 is a DC air pump, and the air pump body 42 is connected in series with the sliding rheostat 34. When the weight of the reactor body 5 is greater, the first spring 33 is compressed more, the resistance of the sliding rheostat 34 is smaller, the current in the circuit is greater, and the power of the air pump body 42 is higher, ensuring the stability of the insurance component 7. When the weight of the reactor body 5 is smaller, the first spring 33 is compressed less, the resistance of the sliding rheostat 34 is higher, the current in the circuit is smaller, and the power of the air pump body 42 is higher. The rate becomes lower, while ensuring the stability of the insurance component 7, it can save energy. The inner wall of the airtight ring 41 is fixedly installed with an annular airbag 43 for clamping the reactor body 5. Specifically, two mounting grooves are symmetrically provided on the inner wall of the airtight ring 41. The upper and lower edges of the annular airbag 43 are respectively fixedly connected to the two mounting grooves. The outer surface of the annular airbag 43 is a non-slip TPU textured film, the middle layer is a high-strength cord reinforcement layer, and the inner layer is an EPDM rubber airtight layer. This composite structure can ensure that the annular airbag 43 has pressure resistance, tear resistance, and anti-slip properties while being flexibly clamped. Several air inlet pipes 414 are equidistantly installed on the inner wall of the airtight ring 41. The air inlet pipes 414 are used to connect the inside of the airtight ring 41 with the inside of the annular airbag 43. Ball valves 44 are slidably installed in the several air inlet pipes 414, and a second spring 45 is fixedly installed on the outer wall of the ball valve 44. For details, please refer to Figure 11 、 Figure 12 A contact ring is provided at one end of the inner wall of the air intake pipe 414 close to the annular airbag 43, and a blocking ring is provided at one end of the inner wall of the air intake pipe 414 close to the airtight ring 41. The contact ring is made of rubber, and the ball valve 44 abuts against the inner wall of the abutment ring. The end of the second spring 45 away from the ball valve 44 is fixedly connected to the end face of the blocking ring. The second spring 45 releases the elastic force to abut the ball valve 44 against the abutment ring. At this time, the air intake pipe 414 is closed.

[0048] See also Figures 9 to 12The trigger assembly 6 includes a trigger rod 61, which is slidably mounted on the outer wall of the airtight ring 41. Specifically, a plurality of sliding cylinders 413 are equidistantly arranged on the circumference of the outer wall of the airtight ring 41. The positions of the plurality of sliding cylinders 413 correspond to the positions of the plurality of air inlet pipes 414. The trigger rod 61 is slidably inserted into the sliding cylinder 413. The trigger rod 61 is made of metal and has a certain weight. It can automatically move downward in the sliding cylinder 413 by its own weight. A fixing ring 62 is fixedly mounted on the outer wall of the trigger rod 61. A trigger rope 63 is fixedly connected to the outer wall of the fixing ring 62. The end of the trigger rope 63 away from the fixing ring 62 passes through the outer wall of the airtight ring 41 and is connected to the ball valve 44. The trigger rope 63 is connected to the inner wall of the airtight ring 41. An airtight sleeve 46 is installed at the connection to improve the airtightness inside the airtight ring 41. Specifically, the length of the trigger rod 61 is greater than or equal to the height of the reactor body 5. A blocking ring is provided on the top of the trigger rod 61 to prevent the trigger rod 61 from falling off from the sliding cylinder 413. When the blocking ring abuts against the top surface of the sliding cylinder 413, the trigger rope 63 has a certain margin. The trigger rope 63 is in a relaxed state, and the ball valve 44 continues to close the air inlet pipe 414. Since the length of the trigger rod 61 is greater than or equal to the height of the reactor body 5, when the airtight ring 41 is sleeved on the outer wall of the reactor body 5, the bottom end of the trigger rod 61 first contacts the ground. The airtight ring 41 should be installed in the middle of the outer wall of the reactor body 5. The trigger rod 61 continues to drive the fixing ring 62 and the end of the trigger rope 63 to move upward in the sliding cylinder 413 until the trigger rope 63 is tightened. The trigger rod 61 continues to move in the sliding cylinder 413, and the trigger rope 63 pulls the ball valve 44 out of contact with the abutment ring. At this time, the second spring 45 is compressed, and the air inlet pipe 414 connects the space inside the airtight ring 41 with the space inside the annular airbag 43. The high-pressure gas generated by the air pump body 42 inside the airtight ring 41 enters the space inside the annular airbag 43 through the air inlet pipe 414. The annular airbag 43 expands and deforms, and the anti-slip TPU texture film on the outer wall of the annular airbag 43 abuts against the outer wall of the reactor body 5, fixing the reactor body 5 and clamping it. When lifted into the air, the trigger rod 61 moves downward in the sliding cylinder 413 due to its own weight, and the trigger rope 63 returns to a relaxed state. The second spring 45 releases the elastic force to make the ball valve 44 abut against the abutment ring again, closing the air inlet pipe 414. The air inside the annular airbag 43 cannot be discharged, and the internal air pressure is kept constant until the reactor body 5 is transported to the designated position. When the reactor body 5 descends in the air, the bottom end of the trigger rod 61 contacts the ground first, and the trigger rod 61 drives the fixing ring 62 and the end of the trigger rope 63 to move upward in the sliding cylinder 413, opening the ball valve 44 through the trigger rope 63, and releasing the high-pressure gas in the internal space of the annular airbag 43, automatically completing the unclamping of the reactor body 5.

[0049] See also Figure 9 、 Figure 10 、 Figure 13The safety assembly 7 includes an air cylinder 71 and a safety rod 74. A plurality of first rotating brackets 415 are equidistantly provided on the top circumference of the outer wall of the air-tight ring 41, and a plurality of second rotating brackets 416 are equidistantly provided on the bottom circumference of the air-tight ring 41. The positions of the plurality of second rotating brackets 416 correspond to the plurality of first rotating brackets 415. The top of the air cylinder 71 is hinged to the end of the first rotating bracket 415. The top of the air cylinder 71 is connected to the outer wall of the air-tight ring 41 through a hose. Specifically, the air cylinder 71 is connected to the internal space of the air-tight ring 41 through a hose. A second piston rod 72 is slidably installed in the air cylinder 71, and a third spring 73 is sleeved on the outer wall of the second piston rod 72. Specifically, the top of the third spring 73 abuts against the bottom surface of the second piston rod 72, and the bottom end of the third spring 73 abuts against the inner bottom surface of the air cylinder 71. When the cam 73 is in the air, the cam 73 is in the air, and the second end of the cam 73 is in the air. When the cam 73 is in the air, the cam 73 is in the air. When the cam 73 is in the air, the cam 73 is in the air. When the cam 73 is in the air, the cam 73 is in the air. When the cam 73 is in the air, the cam 73 is in the air. When the cam 73 is in the air, the cam 73 is in the air. When the cam 73 is in the air, the cam 73 is in the air. When the cam 73 is in the air, the cam 73 is in the air. After the first cam 73 is released, the air in the airtight container 71 is opened, and the air inlet pipe 414 is closed. At this time, the air in the airtight ring 41 is first supplied to the air cylinder 71, and the high-pressure gas pushes the second piston rod 72 to move inside the air cylinder 71, compressing the third spring 73. The second piston rod 72 drives the safety lever 74 to rotate at the end of the second rotating bracket 416 through the driving rod 741, compressing the torsion spring, and the safety lever 74 drives the arc rod 742 to rotate until the roller 75 at the end of the arc rod 742 abuts against the bottom surface of the reactor body 5. The arc rods 742 of the several safety components 7 jointly provide support and protection for the bottom of the reactor body 5. At the same time, according to the weight of the reactor body 5, the detection component 3 can change the air pump body 4 2, so as to improve the protection performance of the insurance component 7, the air pump body 42 is connected in series with the sliding rheostat 34. When the weight of the reactor body 5 is greater, the degree of compression of the first spring 33 is greater, the resistance of the sliding rheostat 34 is smaller, the current in the circuit is greater, the power of the air pump body 42 is higher, and the gas transmission efficiency to the gas cylinder 71 is higher, thereby ensuring the stability of the insurance component 7. When the weight of the reactor body 5 is smaller, the degree of compression of the first spring 33 is smaller, the resistance of the sliding rheostat 34 is higher, the current in the circuit is smaller, the power of the air pump body 42 is lower, and the gas transmission efficiency to the gas cylinder 71 is lowered, while ensuring the stability of the insurance component 7, it can save energy. At the same time, in order to prevent the air pressure inside the airtight ring 41 from exceeding the threshold,To prevent damage to the airtight ring 41, a pressure relief hole 711 is provided on the outer wall of the cylinder 71 near the bottom. When the second piston rod 72 moves to the bottom of the cylinder 71, the third spring 73 is compressed to its limit. This indicates that the protective force of the safety assembly 7 is sufficient, and the pressure relief hole 711 automatically relieves pressure from the cylinder 71. At this point, the combined pressure relief rate of the pressure relief holes 711 of the safety assembly 7 is greater than or equal to the air delivery efficiency of the air pump body 42.

[0050] The working principle of the present invention is as follows: when the device is in use, the two first moving carriages 113 slide inside the sliding box 12 respectively, and the stepping motor 14 drives the screw 13 to rotate, thereby driving the first moving carriage 113 connected to the internal threaded sleeve to move linearly, thereby pushing the sliding rail 11 connected thereto to move forward and backward as a whole, completing the longitudinal displacement;

[0051] On the outer wall of the sliding rail 11, the lateral movement component 2 cooperates with the sliding rail 11 through the second moving vehicle 21. The DC motor 22 drives the second moving vehicle 21 to move left and right, indirectly achieving the lateral displacement of the electric hoist 23. The electric hoist 23 is connected to the hook 25 through a steel chain 24, and further links the detection component 3 and the clamping component 4 installed below the hook 25 to grasp and lift the reactor body 5.

[0052] During the hoisting process, the clamping assembly 4 firmly clamps the reactor body 5 through the airtight ring 41 and the annular airbag 43 inside it. When the airtight ring 41 is sleeved on the middle part of the outer wall of the reactor body 5 from above, the trigger rods 61 in the trigger assembly 6 first contact the ground due to their length design. As the airtight ring 41 continues to move downward, the trigger rods 61 push the fixing ring 62 upward, tightening the trigger rope 63 and pulling the ball valve 44 connected to it to break away from the abutment ring, so that the air inlet pipe 414 opens. At this time, the high-pressure gas generated by the air pump body 42 enters the annular airbag 43 through the air inlet pipe 414, causing it to expand and closely contact the reactor body 5 through the non-slip TPU textured film on the surface, thereby completing flexible clamping;

[0053] When the reactor body 5 is lifted into the air, the trigger rod 61 falls back due to gravity, the trigger rope 63 relaxes, and the second spring 45 releases its elastic force to push the ball valve 44 back to close the air inlet pipe 414, so that the annular airbag 43 maintains high pressure gas and maintains the clamping state until the reactor is transported.

[0054] During the clamping process, the detection component 3 can sense the weight of the reactor body 5. The first spring 33 generates different compression amounts according to the weight of the reactor body 5, driving the first piston 32 to slide. The resistance value is adjusted through the connected sliding rheostat 34, indirectly controlling the power of the air pump body 42 connected in series with it, and then adjusting the gas output pressure in real time according to the weight of the reactor, ensuring the stability and energy efficiency of the insurance component 7.

[0055] To further enhance safety, during the clamping process of the annular airbag 43, several safety components 7 are synchronously intervened for protection. As the air pressure in the airtight ring 41 increases, the gas enters the air cylinder 71 through the hose, pushing the second piston rod 72 outward and compressing the third spring 73. The driving rod 741 drives the safety rod 74 to flip, so that the roller 75 on the arc rod 742 is lifted and contacts the bottom surface of the reactor body 5, achieving bottom lifting protection. At the same time, when the second piston rod 72 moves to the limit position, the pressure relief hole 711 at the lower end of the air cylinder 71 automatically releases the air pressure, avoiding damage to components due to overpressure and preventing the reactor from falling due to accidental deflating of the airbag.

[0056] When the reactor is lowered after being hoisted in the air, the air pump body 42 stops working, the gas inside the air cylinder 71 is automatically released, the third spring 73 and the torsion spring release the elastic force to restore the safety component 7 to its initial state, the trigger rod 61 contacts the ground again, the trigger rod 61 moves upward to drive the trigger rope 63, the trigger rope 63 pulls the ball valve 44, compresses the second spring 45, and allows the high-pressure gas to be released through the air inlet pipe 414, the annular air bag 43 quickly loses pressure and contracts, automatically releasing the clamping of the reactor body 5, completing the closed-loop operation of the entire hoisting operation; at this point, the work of the device is completed.

[0057] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
