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

[0022] Example 1: Please refer to Figures 1-4This utility model provides a technical solution: a ship processing and grinding equipment, including a handheld frame 1 and a hand handle 3 fixed on its outer side wall. The handheld frame 1 is used to fix various connecting parts on the equipment, and the hand handle 3 makes it convenient to pick up and use the equipment. Grinding heads 2 are rotatably connected to the outer side wall of the handheld frame 1. The two grinding heads 2 are connected to a transmission mechanism on opposite sides. The transmission mechanism controls the rotation of the two grinding heads 2 to achieve grinding. An adjustment mechanism is provided above the transmission mechanism. The adjustment mechanism controls the two grinding heads 2 to swing horizontally along the center of their opposite direction to adjust the grinding angle between the two grinding heads 2. Before use, the two adjusting gears 13 in the adjustment mechanism mesh and rotate according to the needs, thereby controlling the angle adjustment of the two grinding heads 2 in the horizontal direction. After the angle adjustment is completed, the drive motor 12 in the transmission mechanism drives the drive wheel 11 and the linkage wheel 10 to drive the drive wheel 7 on the shaft wall of the transmission shaft 8 to rotate together, thereby driving the driven wheels 6 on both sides to control the corresponding grinding heads 2 to rotate together, so as to achieve grinding of the surface of ship workpieces or the deeper parts of the ship hull.

[0023] In this embodiment, the transmission mechanism includes a transmission shaft 8 rotatably mounted at the center of the inner wall of the handheld frame 1. A drive wheel 7 is mounted on the shaft wall of the transmission shaft 8. Two driven wheels 6 are meshed on opposite sides of the two drive wheels 7. The two driven wheels 6 are respectively fixedly connected to one end of the corresponding grinding head 2. The transmission mechanism also includes a driven auxiliary wheel 9 mounted below the shaft wall of the transmission shaft 8. A linkage wheel 10 is meshed on one side of the driven auxiliary wheel 9. A drive wheel 11 is meshed on one side of the linkage wheel 10. The lower parts of the linkage wheel 10 and the drive wheel 11 are rotatably mounted below the inner wall of the handheld frame 1. A drive motor 12 is connected to the bottom of the drive wheel 11. The drive motor 12 is mounted on the handheld frame 1.

[0024] In this embodiment, the adjustment mechanism includes two sets of adjustment gears 13 mounted opposite to each other on the handheld frame 1. The adjustment gears 13 are meshed with each other. A transmission wheel 14 is mounted on the top of one of the adjustment gears 13. A meshing wheel 15 is meshed on one side of the transmission wheel 14. An adjustment motor 16 is mounted on the top of the meshing wheel 15. The adjustment motor 16 is mounted on the handheld frame 1.

[0025] In this embodiment, both grinding heads 2 are provided with matching spindles 5 inside. Each grinding head 2 has a baffle 17 at one end opposite to the corresponding spindle 5. Each grinding head 2 has a matching fixing seat 18 at the opposite end opposite to the corresponding spindle 5. The two fixing seats 18 are threadedly installed at the opposite end of the corresponding spindle 5.

[0026] One end of each of the two main shafts 5 is fixedly connected to the opposite side of the driven wheel 6. Both main shafts 5 are rotatably mounted with swing arms 4. Both swing arms 4 are rotatably mounted on a corresponding set of adjusting gears 13, controlling the rotation of the adjusting gears 13 on both sides, which in turn drive the corresponding driving wheel 7 and the grinding head 2 to swing horizontally along the center line of the transmission shaft 8.

[0027] In this embodiment, to further improve the convenience of equipment operation, before processing, the moving platform 22 is used to push the equipment to a suitable position at a distance from the product to be polished, while controlling the polishing surface of the polishing head 2 to contact the product surface. At this time, a lifting platform 19 is installed at the bottom of the drive motor 12, a fixed platform 20 is slidably installed on the outer wall of the lifting platform 19, and a moving platform 22 is installed at the bottom of the fixed platform 20. A screw 21 is installed in the internal thread of the lifting platform 19, and the lower end of the screw 21 is rotatably installed inside the moving platform 22. The lower end of the screw 21 passes through the moving platform 22 and is equipped with a lifting motor 23. The lifting motor 23 is installed inside the moving platform 22. The lifting motor 23 is controlled to drive the screw 21 to rotate inside the lifting platform 19 and the fixed platform 20, thereby driving the lifting platform 19 to move up and down inside the fixed platform 20, so as to realize polishing at different height positions. At the same time, it can also perform up and down polishing during the movement, which is convenient for practical use.

[0028] A counterweight box 24 is installed on the top of the moving table 22 near the grinding head 2. The counterweight box 24 improves the stable operation of the equipment. The transmission mechanism and the adjustment mechanism are jointly provided with a protective cover 25 and are threadedly connected to the inner protective cover 25 of the handheld frame 1 to prevent the internal structure from being directly exposed to the outside and causing safety risks.

[0029] The working principle is as follows: In actual use, the ship processing and grinding equipment is first moved to the vicinity of the ship workpiece or hull maintenance position to be ground via the moving platform 22 to ensure that the equipment is placed stably. According to the height of the grinding part, the lifting motor 23 is operated to drive the screw 21 to rotate within the lifting platform 19 and the fixed platform 20, so that the lifting platform 19 moves up and down within the fixed platform 20. The grinding head 2 is adjusted to a suitable height so that the grinding surface of the grinding head 2 contacts the product surface. Then, according to the shape and angle requirements of the ship workpiece or hull maintenance part, the adjusting motor 16 is started to drive the meshing wheel 15 to rotate, which in turn causes the transmission wheel 14 and the adjusting gear 13 connected to it to rotate. Since the two sets of adjusting gears 13 mesh with each other, the grinding heads 2 on both sides are controlled to swing horizontally along the center of their relative directions, so as to achieve precise adjustment of the grinding angle to adapt to grinding work at different angles, such as the corner inside the cabin or the surface of the workpiece with a certain shape and angle.

[0030] After the angle adjustment is completed, start the drive motor 12. The drive motor 12 drives the drive wheel 11 to rotate. The drive wheel 11 drives the transmission shaft 8 to rotate through the linkage wheel 10 and the driven auxiliary wheel 9. The drive wheel 7 on the transmission shaft 8 rotates accordingly. The drive wheel 7 meshes with the driven wheel 6, driving the driven wheels 6 on both sides to rotate. This causes the grinding head 2 connected to the driven wheel 6 to rotate at high speed, grinding the surface of the ship's workpiece or the hull where maintenance is deep. During the grinding process, the equipment can be moved according to the actual situation. At the same time, the lifting platform 19 can be moved up and down to achieve continuous grinding at different positions and heights, ensuring uniform and efficient grinding effect. After grinding is completed, turn off the equipment, clean up the debris and dust generated during grinding, and perform necessary maintenance and upkeep on the equipment, such as checking the wear of the grinding head 2, for the next use.
