The railway ferry is a multifunctional ro-ro passenger ship carrying trains, cars and passengers. According to the needs of users, the ferry should be equipped with an electric propulsion system. This propulsion system changes the traditional main engine-shafting-propeller propulsion method, but uses four 3000KW generator sets connected to the grid and transmitted to the underwater motor to drive the propeller to achieve propulsion and 360° rotation of the ship. The POD electric propulsion system and the rudder steering module of the system are fixed on the flange of the hull construction, namely the "installation ring" by high-strength bolts. According to the design requirements, the "installation ring" must be processed on site after the hull is built.

Detailed ways

The structure of the movable multi-purpose on-site processing machine tool of the present utility model is described in conjunction with the accompanying drawings and embodiments.

As shown in Figures 1, 2, and 3, the mobile multipurpose on-site processing machine tool of the present invention is generally divided into four parts: a rotating arm part; a transmission part; a cylinder part; an electrical part.

The machine tool includes a cylinder 11, a rotating arm part connected with the cylinder, a transmission part and an electrical part. Described rotating arm part comprises rotating arm 8, and its two sides are respectively provided with a group of transverse feeding tool rest 2 and vertical feeding tool rest 9 that carry out horizontal and vertical feed cutting, below rotating arm 8 is provided with multiple Group thrust shock absorption combination 1. The rotating arm 8 is assembled and welded by steel castings and Q235 steel plates, and the horizontal and vertical feed tool holders 2 and 9 are welded by Q235 steel plates.

The transmission part includes a main shaft 3 assembled in the center of the cylinder 11, and plane thrust bearings 12 are installed at both ends thereof, and the rotating arm 8 is connected above the main shaft 3 by high-strength bolts, and through the plane thrust bearings 12 and multiple sets of thrust and shock absorbing combinations 1 support the rotation of the rotating arm 8, and the bottom of the main shaft 3 is connected with a worm gear reducer 13, which is connected with the planetary cycloid reducer motor 7 through a set of couplings. The electrical part includes a frequency conversion controller 6 and an electrical control box, and the planetary cycloidal pinwheel deceleration motor 7 is electrically connected to the electrical control box.

The thrust damping combination 1 includes an oil cup 1-1 for internal lubrication and a thrust damping block 1-4, the oil cup 1-1 is fixed on the rotating arm 8, and the connecting oil pipe below the oil cup 1-1 Through the flange below the rotating arm 8 and the thrust damping block 1-4, the adjustable bolt 1-2 is arranged on the top of the thrust damping block 1-4, and is fixed on the flange below the rotating arm 8 to adjust The adjustable bolt 1-2 on the thrust damping block 1-4 can make it close to the frictional thrust plane of the flange surface on the cylindrical body 11. At the same time, there is a ring of dust cover 1-3 between the flange below the rotating arm 8 and the cylinder 11. The dust cover 1-3 is made of transparent plastic material to prevent foreign matter from entering the harsh working environment and scratching the thrust surface. And the lubrication situation can be observed at any time.

The working principle of the movable multi-purpose on-site processing machine tool of the utility model:

Drive the electrical control box to make the motor 7 rotate, and the planetary cycloid reducer motor 7 drives the worm gear reducer 13 through the coupling, and then drives the main shaft 3 and the rotating arm 8 through the fixed key to rotate to complete the "electric push installation ring". "That is, the main cutting movement of the flange 4, that is, the flange 4 with a diameter of 3 meters is clamped, and the horizontal feeding mechanism 2 and the longitudinal feeding tool holder 9 assembled on the rotating arm 8 perform vertical and horizontal feeding to complete the cutting. assisted movement.

The machine tool equipment is equipped with a thrust damping combination 1 under the rotating arm 8, and a roughness Ra0.8 friction thrust plane is processed on the upper flange surface of the cylinder body 11, and the lower thrust surface of the thrust damping combination 1 is closely attached to the cylinder. The frictional thrust plane on the flange surface of the body 11 greatly increases the supporting area of the rotating arm 8, thereby solving the problem of reducing the machining vibration only by the plane thrust bearing 12 (it is impossible to choose too large a bearing to increase the supporting thrust area). , Low machining surface precision and other cutting technical problems. Since a plurality of thrust damping assemblies 1 are evenly distributed on the flange surface of the rotating arm 8, the internal lubrication is realized through the external oil cup, which ensures the smooth rotation of the cutting process at various inclination angles.

Through the worm gear and the planetary cycloid pin gear reducer inside the motor, two-stage mechanical deceleration and one-stage electrical frequency conversion deceleration are formed, and a large transmission speed reduction ratio of 1:2000 is realized. It reasonably solves the small space and large transmission speed reduction ratio and can meet the requirements of outputting sufficient torque. Through the plane thrust bearing 12 and four sets of auxiliary thrust shock absorbing blocks, the machine tool equipment solves the processing problems of metal cutting such as large-diameter workpieces that are easy to vibrate and have low precision on the processing surface at various inclination angles. In order to achieve the requirement of a large transmission ratio of 1:2000: the inline drive motor is realized in the first-stage mechanical deceleration planetary cycloid reducer; the second-stage mechanical deceleration is a worm gear. In order to output enough torque, the design of the worm gear and worm is determined to be 10 modules, and the motor is 7.5KW with four-level power. Rough and fine machining of machine tool equipment requires cutting speed.

When working on site, hoist the movable multi-purpose on-site processing machine tool as a whole into the workpiece—the installation ring flange 4, and the position adjustment screw combination 5. It is composed of four sets of horizontal adjustment screws and four sets of upper and lower sets of front, rear, left, and right position adjustment screws. combined. The screw can be directly adjusted by a wrench to fix it at various satisfactory positions, so it is convenient and fast.

The movable multipurpose processing machine tool can be used for processing land machinery, port machinery, etc., and its processing function range is relatively wide.

(1) Workpieces with larger diameters can be processed. The rotary arm 8 adopts Q235 welded structural parts. If workpieces with larger diameters need to be processed, Q235 steel plates can be used to make the structure, and the long rotary arm is directly welded, and the horizontal feed knife The frame 2 and the longitudinal feed tool rest 9 are installed in the corresponding positions, and the maximum diameter can be processed on the spot as a workpiece of 5 meters.

(2) Workpieces with different heights can be processed. When working on the spot as described above, the movable multi-purpose processing machine tool is hoisted into the corresponding position of any height of the workpiece as a whole, and adjusted to the required height by the position adjustment screw combination 5. Just fix it. If the inner diameter of the workpiece is small, because the rotating arm 8 and the main shaft 3 are connected and fastened by high-strength bolts, and there is a seam in the middle for positioning, it is possible to make a tubular structure sub-joint with upper and lower steps to locate the corresponding height, and use high-strength The bolts are connected and tightened, and workpieces with different heights can be processed on site. The maximum height of the elevated cylindrical structure pup joint is 1 meter.

For example, for a large-scale port mechanical ship loader, the technical requirements for the flange plane of the rotary table must be finished after the structural parts are welded. Because the structural parts are too large, it is impossible to transport them into the processing plant for machining. Processing machine tools are fully capable of machining tasks.

In addition, offshore oil platforms are equipped with fixed rotating cranes, and the main structural cylinder must be welded to the connecting flange on site. If deformation occurs, the flange must also be finished. This processing machine tool is also fully capable of processing tasks.
