[0006] When the electromechanical module is lifted or docked, the base plate can be fixed by the support and fixing assembly to prevent the device from moving when lifting or docking the electromechanical module, which may cause accidents. The top of the base plate is fixedly connected to two symmetrically arranged support sleeves, and the inner cavity of the support sleeve is movably provided with a column. The internal thread of the column is connected to the first screw, and the bottom ends of the two first screws are jointly linked and connected to the first driving unit; the first driving unit structure is that the light rod at the lower end of the first screw cooperates with the bearing seat provided in the support sleeve, and the light rod end of the first screw extending from the bottom of the bearing seat is installed with a bevel gear, and dual-axis motors are respectively arranged in the middle of the two symmetrical base plates, and the shaft ends of the transmission shafts on both sides of the dual-axis motor are respectively installed with bevel gears, and the bevel gears are meshed with the corresponding bevel gears of the first screw. Used to drive the first screw to rotate, a top plate is fixedly connected to the top ends of the four columns, and two symmetrically arranged fixing frames are fixedly connected to the bottom of the top plate. The two fixing frames are located between the two bottom plates, and two second screws are rotatably connected inside the fixing frames. A second driving unit located on the top of the top plate is commonly and linkedly connected to the top ends of the two second screws; the second driving unit structure is that the upper ends of the two second screws extending out of the through holes of the top plate are respectively fixed with gears, and the motor arranged on the top plate drives the gears of the two second screws through the installed intermediate gear. The second driving unit is used to drive the second screw rod to rotate, and a lifting seat is commonly threadedly connected to the surfaces of the two second screw rods, and a number of driving horizontal cylinders are fixedly connected to the opposite surfaces of the two lifting seats on both sides, and a clamping plate is commonly fixedly connected to the output ends of the driving horizontal cylinders on the same side, and the electromechanical module is clamped and fixed by the cooperation of the two clamping plates, and a flexible pad is fixedly connected to the clamping surface of the clamping plate, which can protect the electromechanical module and prevent the clamping plate from causing damage to the electromechanical module.

By setting up a protective lifting mechanism, it can play an auxiliary and protective role when lifting the electromechanical module. By using a cable sleeve set at both ends of the electromechanical module and then hanging the cable on the protective lifting mechanism, while the above-mentioned structure lifts the electromechanical module, the protective lifting mechanism is used to assist in lifting the electromechanical module, which can not only share part of the lifting pressure, but also play a protective effect, thereby preventing the electromechanical module from falling off during the clamping and lifting process, causing damage to the electromechanical module.The device is moved to the top of the electromechanical module by the provided moving wheels, so that the electromechanical module is located between the two clamping plates, and then the driving horizontal cylinders on both sides are started to drive the clamping plates on both sides to move relative to each other to clamp the electromechanical module in the middle, and then the lifting seat is driven to move upward by the second driving unit to drive the electromechanical module to lift upward, so that the electromechanical module will not shake during the lifting process, thereby improving the stability of the device during use and facilitating pipeline docking. When the lifting seat rises to the maximum value and the lifting height of the electromechanical module is still not enough, the first driving unit can drive the first screw to rotate, thereby driving each column to drive the top plate to rise upward, so as to further increase the height of the electromechanical module and improve the scope of application of the device.

[0009] The second driving unit includes a gear fixedly connected to the top end of the second screw rod, an intermediate gear rotatably connected between the two gears, the two gears are meshed with the intermediate gear, the top of the intermediate gear is connected to the motor through a rotating shaft, and the motor is fixedly connected to the top of the top plate through a connecting plate. When the second driving unit is in use, the motor is started to drive the intermediate gear to rotate, and then the gears on both sides are synchronously driven to drive the second screw rod to rotate.

[0010] An X-shaped bracket is fixedly connected between the two supporting sleeves on the top of the bottom plate, which strengthens and fixes the two supporting sleeves and improves the overall supporting strength, making the device more stable during the lifting process of the electromechanical module.

The limiting column is slidably arranged in the limiting guide groove. By setting the limiting guide groove and the limiting column, a limiting effect can be played on the column to prevent the column from separating from the supporting sleeve when moving upward.

[0012] A handle is fixedly connected to the outer side of the supporting sleeve, so that the staff can push the device conveniently.

[0013] A protective cover is detachably provided on the top of the top plate by means of a number of bolts. The second drive unit and the protective lifting mechanism are both located inside the protective cover. A number of second heat sinks are evenly distributed on the outside of the protective cover, which can dissipate heat for the internal electrical equipment and extend its service life. The protective cover can protect the second drive unit and the protective lifting mechanism from damage caused by external factors. The detachable setting of the protective cover facilitates the maintenance and replacement of internal components.

[0014] When the protective lifting mechanism is in use, a cable sleeve is installed at both ends of the electromechanical module, and then the cable is hung on the hook. When the electromechanical module is lifted, the second drive motor is started at the same time to drive the retractable shaft to rotate and reel in the wire rope, thereby assisting the lifting of the electromechanical module. It can not only share part of the lifting pressure, but also have a protective effect to prevent the electromechanical module from falling off during the clamping and lifting process, causing damage to the electromechanical module. The set pulley can protect the wire rope and prevent the wire rope from contacting the through groove and causing wear of the wire rope.

[0015] When in use, the device is moved to the top of the electromechanical module by the provided moving wheels, so that the electromechanical module is located between the two clamping plates, and then the driving horizontal cylinders on both sides are started to drive the clamping plates on both sides to move relative to each other, so as to clamp the electromechanical module in the middle, and then the lifting seat is driven to move upward by the second driving unit, thereby driving the electromechanical module to be lifted upward. In this way, the electromechanical module will not shake during the lifting process, thereby improving the stability of the device during use and facilitating pipeline docking. When the lifting seat rises to the maximum value and the lifting height of the electromechanical module is still not enough, the first driving unit can be used to drive the first screw to rotate, thereby driving the columns to drive the top plate to rise upward, thereby further increasing the height of the electromechanical module and improving the scope of application of the device.

In this way, the electromechanical module will not shake during the lifting process, thereby improving the stability of the device during use and facilitating pipeline docking. When the lifting seat rises to the maximum value and the lifting height of the electromechanical module is still not enough, the first driving unit can drive the first screw rod to rotate, thereby driving each supporting rod to drive the top plate to rise upward, thereby further improving the height of the electromechanical module and improving the scope of application of the present device.
