It is mainly used for the most difficult to utilize heavy parts, and hydrogenates the residual oil into light oil, thereby producing gasoline, diesel, etc. The distribution plate of the hydrogenation reactor needs to be replaced every 2 to 3 years of operation. When replacing, the old distribution plate needs to be removed from the outer tube, and then the new distribution plate needs to be installed in the outer tube.

The side of the scooter close to the upper track is provided with multiple groups of second guide wheels, the two side guides of the lower track are located between each group of first guide wheels, the two side guides of the upper track are located between each group of second guide wheels, and the top surface of the scooter is fixedly connected to the crane arm.

[0004] In the above case, during the process of disassembling and installing the distribution plate, it is necessary to connect the distribution plate with the suspension arm so that the distribution plate is fixedly connected to the suspension arm, then pull the distribution plate out of the outer tube, then cancel the connection between the distribution plate and the suspension arm, then install a new distribution plate on the suspension arm, then put the new distribution plate into the outer tube, then cancel the connection between the new distribution plate and the suspension arm, and take the suspension arm out of the outer tube;

[0005] Since the distribution plate is relatively large and is located inside the outer tube, during the process of disassembling and installing the distribution plate, a person needs to manually enter the outer tube and perform manual operations, which increases the difficulty of disassembly and installation.

[0006] To this end, the present invention proposes a disassembly and assembly tool for a hydrogenation reactor distribution plate to solve the above-mentioned problem. Summary of the invention

[0067] Also includes:

[0068] A mounting seat 1, the top of which is provided with an arc-shaped groove for facilitating the placement of the outer tube 2;

[0069] Specifically, in the prior art, since the distribution plate 3 is relatively large and is located inside the outer tube 2, during the process of disassembling and installing the distribution plate 3, it is necessary to manually enter the outer tube 2 for manual operation, thereby increasing the difficulty of disassembly and installation. The present technical solution can solve the above problems. The specific operation is as follows: first, the bracket 6 is driven by the guide rail 5, so that the bracket 6 drives the boom 9 to approach the distribution plate 3, and the bracket 6 can be driven to move by a hydraulic cylinder or a screw rod;

[0070] In 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, and then by starting the flip driving assembly, several flip plates 14 are flipped, so that the flip plates 14 are in contact with the side walls of the distribution plate 3, and under the common limiting of the mounting plate 11 and the flip plates 14, the distribution plate 3 is limited on the first limiting rods 12, and in the process of the flip plate 14 flipping, the support plate 15 is flipped, so that a stable tripod is formed between the support plate 15 and the flip plate 14, thereby providing a stable supporting force for the flip plate 14;

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

[0072] Then replace the new distribution plate 3, and according to the above operation, send the new distribution plate 3 into the outer tube 2 and connect it with the outer tube 2;

During the movement of the driving shell 18, the I-shaped driving plate 22 moves along the inner cavity 19 and pushes the flip block 20, so that the flip block 20 flips, and the torsion spring 21 is compressed. Since the flip block 20 and the flip plate 14 are coaxially fixed, the flip block 20 flips to make the flip plate 14 flip. Under the common limit of the mounting plate 11 and the flip plate 14, the distribution plate 3 is limited on the first limiting rod 12;

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