[0002] A hydrogenation reactor is a main equipment commonly used in the petroleum industry, mainly used for the most difficult-to-utilize heavy part, converting residue oil into light oil by hydrogenation, so as to produce gasoline, diesel, etc. The distribution plate of the hydrogenation reactor needs to be replaced every 2 - 3 years of operation. When replacing, the old distribution plate needs to be taken out from the outer pipe, and then the new distribution plate is installed into the outer pipe.

[0003] For example, the invention patent with the publication number of CN117069017A discloses a special tooling for disassembly and assembly of the distribution plate of a hydrogenation reactor, including a fixed bottom plate, a fixed seat plate, a fixed double rail, a scooter, and a lifting arm. The fixed bottom plate is detachably connected to the cross beam of the distribution plate of the hydrogenation reactor, and the fixed bottom plate is fixedly connected to the fixed seat plate through bolts. The bottom surface of the fixed seat plate is provided with multiple groups of first guide wheels. The fixed double rail includes an upper rail and a lower rail, and the upper rail and the lower rail are fixedly connected. One side of the scooter close to the upper rail is provided with multiple groups of second guide wheels. The two side rails of the lower rail are located between each group of first guide wheels, and the two side rails of the upper rail are located between each group of second guide wheels. The top surface of the scooter is fixedly connected to the lifting arm.

[0004] For the above case, during the process of disassembling and installing the distribution plate, it is necessary to connect the lifting arm to the distribution plate, fix the distribution plate to the lifting arm, then pull the distribution plate out of the outer pipe, then cancel the connection between the distribution plate and the lifting arm, then install a new distribution plate on the lifting arm, then send the new distribution plate into the outer pipe, then cancel the connection between the new distribution plate and the lifting arm, and take out the lifting arm from the outer pipe;

[0005] Since the distribution plate is large in volume and located inside the outer pipe, during the process of disassembling and installing the distribution plate, it is necessary for workers to enter the inside of the outer pipe for manual operation, thus increasing the difficulty of disassembly and installation.

[0006] Therefore, the present invention proposes a disassembly and assembly tooling for the distribution plate of a hydrogenation reactor to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0058] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0059] As Figures 1 to 8 shown, a disassembly and assembly tooling for a hydrogenation reactor distribution plate includes:

[0060] A guide rail 5, on the top of which a bracket 6 is slidably connected, and at the top of the bracket 6 a lifting arm 9 is fixedly connected;

[0061] A mounting plate 11, which is rotatably connected to the end of the lifting arm 9;

[0062] Several first limiting rods 12, which are fixedly connected to the side wall of the mounting plate 11 in an annular array. The radius of the first limiting rod 12 is smaller than the radius of the through hole 4 of the distribution plate 3, so that the first limiting rod 12 can be inserted into the through hole 4;

[0063] Two inner grooves 13, which are symmetrically opened on the outer side wall of the first limiting rod 12;

[0064] Two flipping plates 14, which are symmetrically rotatably connected in the inner grooves 13;

[0065] A support plate 15, one end of which is rotatably connected to the side wall of the flipping plate 14, and the other end is rotatably connected with a sliding pin 16, and the sliding pin 16 is slidably connected to the side wall of the inner groove 13;

[0066] A flipping driving assembly, which is used to drive the flipping plate 14 to flip so that the flipping plate 14 contacts the end face of the distribution plate 3, and the distribution plate 3 is limited on the first limiting rod 12;

[0067] It further includes:

[0068] A mounting seat 1, on the top of which an arc-shaped groove is opened to facilitate the placement of the outer pipe 2;

[0069] Specifically, in the prior art, due to the large volume of the distribution plate 3 and it is located inside the outer pipe 2, during the process of disassembling and installing the distribution plate 3, it is necessary for workers to enter the inside of the outer pipe 2 for manual operation, thus increasing the difficulty of disassembly and installation. This technical solution can solve the above problems. The specific operation is as follows. First, drive the bracket 6 through the guide rail 5, so that the bracket 6 drives the lifting arm 9 to approach the distribution plate 3. The bracket 6 can be driven to move by means of a hydraulic cylinder push or a lead screw, etc.;

[0070] During the process of the bracket 6 approaching the distribution plate 3, several first limiting rods 12 are correspondingly inserted into the through holes 4 of the distribution plate 3. Then, by starting the flipping drive assembly, several flipping plates 14 are flipped, so that the flipping plates 14 contact the side wall of the distribution plate 3. Under the combined limitation of the mounting plate 11 and the flipping plates 14, the distribution plate 3 is limited on the first limiting rods 12. And during the flipping process of the flipping plates 14, the support plate 15 is flipped, so that a stable triangular frame is formed between the support plate 15 and the flipping plates 14, thereby providing a stable supporting force for the flipping plates 14;

[0071] During the process of the guide rail 5 driving the bracket 6 to drive the boom 9 to reset, under the limiting action of the flipping plates 14, the distribution plate 3 is separated from the outer tube 2. After separation, the flipping plates 14 are reset by the flipping drive assembly, thereby canceling the limiting action on the distribution plate 3, so that the distribution plate 3 can be separated from the first limiting rods 12;

[0072] Then, a new distribution plate 3 is replaced, and the new distribution plate 3 is sent into the outer tube 2 and connected to the outer tube 2 according to the above operations;

[0073] The disassembly and assembly tooling of the distribution plate 3 enables the distribution plate 3 to be quickly and automatically installed and disassembled from the boom 9 by setting the mounting plate 11, the first limiting rods 12 and the flipping plates 14, reducing the disassembly and assembly difficulty and improving the disassembly and assembly speed.

[0074] As a further implementation scheme of the present invention, the flipping drive assembly includes:

[0076] Inner cavity 19, the inner cavity 19 is opened in the first limiting rod 12;

[0077] Flipping block 20, the flipping block 20 is coaxially fixed with the flipping plate 14, and a torsion spring 21 is fixedly connected between the flipping block 20 and the wall of the inner cavity 19;

[0078] I-shaped drive plate 22, the I-shaped drive plate 22 is slidably connected in the inner cavity 19, and the I-shaped drive plate 22 is fixedly connected to the side wall of the drive shell 18;

[0079] Specifically, by setting the driving housing 18, the flipping block 20 and the I-shaped driving plate 22, after the first limiting rod 12 is correspondingly inserted into the through hole 4 of the distribution plate 3, by starting the cylinder 17, the telescopic rod of the cylinder 17 pulls the driving housing 18 to move closer to the mounting plate 11. During the movement of the driving housing 18, the I-shaped driving plate 22 moves along the inner cavity 19 and pushes the flipping block 20, causing the flipping block 20 to flip, and the torsion spring 21 is compressed. Since the flipping block 20 and the flipping plate 14 are coaxially fixed, the flipping of the flipping block 20 causes the flipping plate 14 to flip. Under the combined limitation of the mounting plate 11 and the flipping plate 14, the distribution plate 3 is limited on the first limiting rod 12;

[0080] After the distribution plate 3 is taken out of the outer tube 2, by starting the cylinder 17, the telescopic rod of the cylinder 17 pushes the driving housing 18 to move, causing the driving housing 18 to move away from the mounting plate 11, and the I-shaped driving plate 22 to move away from the flipping block 20. Under the action of the torsion spring 21, the flipping plate 14 is reset to cancel the limitation on the distribution plate 3, so that the distribution plate 3 can be detached from the first limiting rod 12, reducing the difficulty of disassembly and installation.

[0082] Specifically, by setting the expansion airbag 23, during the movement of the I-shaped driving plate 22 along the inner cavity 19, the space of the inner cavity 19 is occupied, so that the gas in the inner cavity 19 is compressed and the air pressure increases, thereby causing the expansion airbag 23 to expand and come into contact with the inner wall of the through hole 4, further improving the connection stability between the distribution plate 3 and the lifting arm 9, avoiding the shaking of the distribution plate 3 when the distribution plate 3 is sent into the outer tube 2, and improving the stability during installation.

[0083] As a further embodiment of the present invention, several telescopic frames 24 are fixedly connected to the surface of the mounting plate 11 in a circumferential array. The top of the telescopic frame 24 is fixedly connected with a mounting block 25, and a second limiting rod 26 is fixedly connected to the side wall of the mounting block 25.

[0085] Specifically, by setting the second limiting rod 26 and the telescopic frame 24, during the process of inserting the first limiting rod 12 into the through hole 4, several second limiting rods 26 are synchronously inserted into the through holes 4 at other positions. Then, through the lifting and adjusting assembly, the second limiting rods 26 respectively abut against the inner wall of the through hole 4. On the one hand, it supports the distribution plate 3, reducing the load of the distribution plate 3 on the first limiting rod 12. On the other hand, through the frictional contact force between the second limiting rod 26 and the inner wall of the through hole 4, the stability of the connection between the distribution plate 3 and the boom 9 is further improved.

A first elastic connecting member is connected between the sliding frame 29 and the driving housing 18;

[0090] Specifically, by setting the driving inclined grooves 2501 and the U-shaped pushing frame 27, during the process of the driving housing 18 approaching the mounting plate 11, the connecting pins 28 on both sides of the U-shaped pushing frame 27 move along the driving inclined grooves 2501. Driven by the driving inclined grooves 2501, several mounting blocks 25 drive the second limiting rods 26 away from the boom 9, so that the second limiting rods 26 respectively abut against the inner wall of the through hole 4, further improving the stability of the connection between the distribution plate 3 and the boom 9.

[0091] As a further embodiment of the present invention, the first elastic connecting member includes:

[0092] A sliding seat 30 is fixedly connected to the outer side wall of the driving housing 18;

[0094] A compression spring 32 is sleeved on the surface of the sliding rod 31, and both ends of the compression spring 32 are respectively fixedly connected to the side walls of the sliding seat 30 and the sliding frame 29;

[0095] Specifically, by setting the compression spring 32, during the process of the driving housing 18 driving the U-shaped push frame 27 to approach the mounting plate 11, the compression spring 32 generates pressure, which is conducive to making the second limiting rod 26 fully contact the inner wall of the through hole 4, improving the contact friction between the second limiting rod 26 and the inner wall of the through hole 4, and further improving the connection stability between the distribution plate 3 and the boom 9.

Then, by starting the flipping drive assembly, several flipping plates 14 are flipped, so that the flipping plates 14 contact the end face of the distribution plate 3. Under the combined limitation of the mounting plate 11 and the flipping plates 14, the distribution plate 3 is limited on the first limiting rods 12. And during the flipping process of the flipping plates 14, the support plate 15 is flipped, so that a stable triangular frame is formed between the support plate 15 and the flipping plates 14, thereby providing a stable supporting force for the flipping plates 14;

[0107] During the process of the guide rail 5 driving the support 6 to drive the boom 9 to reset, under the limiting effect of the turning plate 14, the distribution disc 3 is disengaged from the outer tube 2. After the disengagement, the turning plate 14 is reset through the turning drive assembly, thereby canceling the limiting effect on the distribution disc 3, enabling the distribution disc 3 to be separated from the first limiting rod 12;

[0108] Then, a new distribution disc 3 is replaced, and the new distribution disc 3 is sent into the outer tube 2 and connected to the outer tube 2 according to the above operations.
