Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1-3This utility model provides a technical solution: an isooctane reactor mechanical seal maintenance device, including a U-shaped main frame 110, a base 111 fixedly installed at the bottom of the main frame 110, symmetrically arranged strip-shaped holes on the main frame 110, a U-shaped frame 120 slidably installed on the inner wall of the strip-shaped holes, a lifting assembly installed on the U-shaped frame 120, the lifting assembly including a threaded rod 160, a first rotating shaft 161 and a second motor 162, the threaded rod 160 rotatably installed between the two sides of the inner wall of the strip-shaped holes, the two threaded rods 160 are symmetrically arranged and the second rotating shaft is fixedly installed at the top, the top of the second rotating shaft passes through the top of the main frame 110 and is fixedly installed with a first bevel gear, side plates are symmetrically fixedly installed at the top of the main frame 110, and two... A first rotating shaft 161 is rotatably installed between the side plates. A second motor 162 is fixedly installed at one end of the first rotating shaft 161. A second bevel gear is symmetrically fixedly installed on the first rotating shaft 161. The first bevel gear and the second bevel gear are meshed and connected. A groove is provided on the U-shaped frame 120. A support shaft 121 is rotatably installed between the two sides of the inner wall of the groove. An adjustment component is installed at one end of the support shaft 121. A support plate 122 is fixedly installed on the support shaft 121. A support frame 130 is installed on one side of the support plate 122. A handle bar 131 is rotatably installed at the top of the inner wall of the support frame 130. A first motor 132 is fixedly installed at the top of the handle bar 131. The bottom end of the handle bar 131 slides through the bottom end of the support frame 130 and engages with a wrench part 140.

[0025] In some specific implementation schemes, a horizontal plate 150 is fixedly installed at the bottom between the two sides of the inner wall of the main frame 110. A cylinder 151 is fixedly installed at the top of the horizontal plate 150. The output end of the cylinder 151 passes through the horizontal plate 150 and is fixedly installed on a base plate 152. Pulleys are installed at the four corners of the bottom of the base plate 152. When the bottom of the horizontal plate 150 is in contact with the top of the base plate 152, the bottom of the pulleys is higher than the bottom of the base 111. When the equipment needs to be moved, the cylinder 151 drives the base plate 152 to move down, so that the pulleys support the ground, facilitating the movement of the equipment. With the implementation of this system, when the equipment reaches the maintenance position, the cylinder 151 rises to detach the base plate 152 from the ground, and the horizontal plate 150 provides stable support to ensure the smooth progress of maintenance work.

[0028] In some specific implementation schemes, an angle plate 1206 is fixedly installed on one side of the U-shaped frame 1204, and a needle bar 1207 is fixedly installed on one end of the third rotating shaft 1205. One end of the needle bar 1207 slides through the U-shaped frame 1204 and the angle plate 1206 and is fixedly installed with a needle 1208. The angle of rotation of the wrench part 140 can be read and recorded intuitively by the indication of the needle 1208 on the angle plate 1206. This design not only improves the accuracy and traceability of angle adjustment, but also provides maintenance personnel with a more intuitive and convenient operating experience.

[0029] Please see Figure 5 A spring 1311 is fixedly installed at the top of the inner wall of the glove handle 131. A slider 1312 is fixedly installed at one end of the spring 1311. A second limiting block 1313 is symmetrically fixedly installed on the outer side of the slider 1312. A second limiting groove matching the second limiting block 1313 is provided on the inner wall of the glove handle 131. The slider 1312 is slidably connected to the inner wall of the glove handle 131. The wrench component 140 includes a circular plate 141, a positioning block 142, and an output head 143. The positioning block 142 and the output head 143 are symmetrically fixedly installed at both ends of the circular plate 141. A magnetic suction plate is fixedly installed at the top of the positioning block 142. A square groove matching the positioning block 142 is provided at the bottom of the slider 1312. A magnetic suction piece that attracts the magnetic suction plate is installed at the top of the inner wall of the square groove. The circular plate 141 is slidably connected to the inner wall of the glove handle 131.

[0030] In some specific implementations, multiple wrench parts 140 are inserted into one side of the top of the U-shaped frame 120, and the output head 143 of each wrench part 140 is of a different model. The output head 143 can be in the shape of internal hexagon, parallel or cross, etc., which makes it easier to quickly change to the appropriate wrench part 140 according to needs, thereby improving work efficiency.

[0031] Working principle: In use, the starting cylinder 151 moves the base plate 152 down to the pulley support ground, at which point the equipment can be moved to the maintenance area. The starting electric push rod 133 moves the support frame 130, thereby adjusting the distance between the output head 143 and the disassembled part. At this time, a wrench 140 matching the output head 143 can be selected according to the specifications of the disassembled part. The starting second motor 162 drives the first rotating shaft 161 to rotate. The rotation of the first rotating shaft 161, through the cooperation of the first bevel gear, the second bevel gear, and the second rotating shaft, drives the threaded rod 160 to rotate. The rotation of the threaded rod 160 drives the U-shaped frame 120 to rise and fall, thereby adjusting the height of the wrench until the output head 143 is inserted into the zero position. Within the component, the first motor 132 is activated to rotate the handle lever 131. The rotation of the handle lever 131 causes the wrench component 140 to rotate, allowing for the disassembly or installation of parts. Simultaneously, when the required angle for installation or disassembly is needed, the third motor 1203 can be activated to rotate the worm gear 1202. The rotation of the worm gear 1202, in conjunction with the worm wheel 1201, drives the third rotating shaft 1205 to rotate. The rotation of the third rotating shaft 1205 causes the support plate 122 to rotate, thereby adjusting the angle of the wrench component 140. At the same time, the rotation of the third rotating shaft 1205, through the needle rod 1207, drives the needle head 1208 to rotate. The needle head 1208, in conjunction with the angle plate 1206, allows for precise rotation of the angle.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
