Technical Field

[0001] This utility model relates to the field of lifting fixture technology, specifically a battery module lifting fixture for ships. Background Technology

[0002] Utility model patent CN204607356U discloses a hoisting fixture for vehicle-mounted power battery modules, comprising: a fixture body mounted on top of the battery module; several docking mechanisms, each penetrating the fixture body and connecting it to the battery module; positioning insulating plates disposed at the bottom of both ends of the fixture body; and several accessory storage boxes arranged within cavities on the top of the fixture body for housing the docking mechanisms. This utility model improves the assembly efficiency of power battery pack systems during production, significantly reduces the labor intensity of workers, and simplifies, enhances, and ensures the safety and reliability of the entire operation.

[0003] However, when hoisting ship battery modules, the number of batteries varies, resulting in significant differences in the specifications and dimensions of the battery modules. The device uses clamping fixtures to clamp and limit the battery modules, but this device can only clamp and hoist batteries with a small size range, resulting in low applicability. At the same time, the battery modules will shake when affected by external forces, causing the battery modules to loosen on the fixtures, resulting in low stability. Utility Model Content

[0004] The purpose of this utility model is to provide a battery module hoisting fixture for ships, which solves the problem that the battery modules vary greatly in size due to different numbers of batteries. The device uses clamping fixtures to clamp and limit the battery modules, but this device can only clamp and hoist batteries with a small size range, which has low applicability. At the same time, the battery modules will shake when affected by external forces, causing the battery modules to loosen on the fixture, resulting in low stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery module lifting clamp for ships, comprising a steel cable, a hanger fixedly connected to the lower end of the steel cable, a lifting frame fixedly connected to the lower end of the hanger, a lifting plate fixedly connected to the lower end of the lifting frame, a cylinder fixedly mounted on the upper end of the lifting frame, the cylinder rod of the cylinder passing through the lifting frame and slidably connected to the lifting frame, a clamping mechanism provided on the cylinder, a clamping plate provided on the clamping mechanism, a guide wheel rotatably connected inside the clamping plate, an eccentric wheel rotatably connected inside the clamping plate, a support shaft fixedly connected to the surface of the eccentric wheel, and a torsion spring provided on the outer side of the support shaft.

[0006] Preferably, one end of the torsion spring is fixedly connected to the eccentric wheel, and the other end of the torsion spring is fixedly connected to the clamping plate. By providing the torsion spring, the eccentric wheel can be easily reset.

[0007] Preferably, the clamping mechanism includes a pressure frame, the lower end of the cylinder rod of the cylinder is fixedly connected to the pressure frame, an inclined rod is slidably connected inside the pressure frame, a top plate is slidably connected inside the inclined rod, a support plate is fixedly connected to the upper end of the hanging plate, a motor is fixedly mounted on the surface of the support plate, the rotating shaft of the motor passes through the support plate and is rotatably connected to the support plate, a double-ended screw is fixedly connected to the front end of the rotating shaft of the motor, the double-ended screw is rotatably connected to the support plate, a hanging rod is slidably connected inside the pressure frame, a pressure plate is fixedly connected to the lower end of the hanging rod, and a spring is provided on the outer side of the hanging rod. The device uses a motor to drive a bidirectional screw to rotate and the top plate to make a threaded movement, which in turn changes the distance between the diagonal rods located on the outer sides of the two top plates, thereby changing the position of the clamping plate. The cylinder drives the pressure frame to move and the diagonal rods to slide, allowing the device to clamp and lift batteries of different lengths and widths. A spring elastically presses down the pressure plate, causing the pressure plate to contact the battery and subjecting the battery to downward pressure. The eccentric wheel supports the battery, and when the battery shakes, it causes the eccentric wheel to shift, pushing the battery upward and cooperating with the spring to prevent the battery from sliding on the clamping plate, making the battery lifting more stable.

[0008] Preferably, the diagonal brace and the hanging plate are slidably connected, and the diagonal brace and the clamping plate are fixedly connected. The movement of the clamping plate is controlled by setting the diagonal brace.

[0009] Preferably, the inclined rod is internally slidably connected to a sliding rod, which is slidably connected to the hanging frame. By providing the sliding rod, the movement of the inclined rod becomes more stable.

[0010] Preferably, the bidirectional screw and the top plate are connected by threads, and the top plate and the hanging plate are slidably connected. The movement of the top plate is controlled by the bidirectional screw.

[0011] Preferably, one end of the spring is fixedly connected to the pressure frame, and the other end of the spring is fixedly connected to the pressure plate. By setting the spring, the pressure plate is elastically compressed downwards.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a motor to drive a bidirectional screw to rotate and the top plate to make a threaded movement, thereby changing the distance between the inclined rods located on the outer sides of the two top plates, which in turn changes the position of the clamping plate. Furthermore, the pressure frame is moved and the inclined rods are slid by a cylinder, thus enabling the device to clamp and lift batteries of different lengths and widths.

[0014] 2. This utility model uses a spring to elastically press down the pressure plate, thereby bringing the pressure plate into contact with the battery and subjecting the battery to downward pressure. The eccentric wheel supports the battery, and when the battery shakes, it drives the eccentric wheel to shift, causing the battery to be pushed upward and working in conjunction with the spring. This makes it less likely for the battery to slide on the clamp, making the battery hoisting more stable. Attached Figure Description

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] Please see Figure 1 , Figure 4 , Figure 5A battery module lifting clamp for ships includes a steel cable 1, a hanger 2 fixedly connected to the lower end of the steel cable 1, a lifting frame 3 fixedly connected to the lower end of the hanger 2, a lifting plate 4 fixedly connected to the lower end of the lifting frame 3, a cylinder 5 fixedly mounted on the upper end of the lifting frame 3, the cylinder rod of the cylinder 5 passing through the lifting frame 3 and slidably connected to the lifting frame 3, a clamping mechanism 6 provided on the cylinder 5, a clamping plate 7 provided on the clamping mechanism 6, a guide wheel 8 rotatably connected inside the clamping plate 7, an eccentric wheel 9 rotatably connected inside the clamping plate 7, a support shaft 10 fixedly connected to the surface of the eccentric wheel 9, a torsion spring 11 provided on the outer side of the support shaft 10, one end of the torsion spring 11 fixedly connected to the eccentric wheel 9, and the other end of the torsion spring 11 fixedly connected to the clamping plate 7. By providing the torsion spring 11, the eccentric wheel 9 can be easily reset.

[0023] Please see Figures 1-3 The clamping mechanism 6 includes a pressure frame 61. The lower end of the cylinder rod of the cylinder 5 is fixedly connected to the pressure frame 61. An inclined rod 62 is slidably connected inside the pressure frame 61. The inclined rod 62 is slidably connected to the hanging plate 4 and fixedly connected to the clamping plate 7. The movement of the clamping plate 7 is controlled by the inclined rod 62. A sliding rod 63 is slidably connected inside the inclined rod 62 and slidably connected to the hanging frame 3. The movement of the inclined rod 62 is more stable by the sliding rod 63. A top plate 64 is slidably connected inside the inclined rod 62. A support plate 65 is fixedly connected to the upper end of the 4. A motor 66 is fixedly installed on the surface of the support plate 65. The rotating shaft of the motor 66 passes through the support plate 65 and is rotatably connected to the support plate 65. A double-ended screw 67 is fixedly connected to the front end of the rotating shaft of the motor 66. The double-ended screw 67 is threadedly connected to the top plate 64. The top plate 64 is slidably connected to the hanging plate 4. The movement of the top plate 64 is controlled by the double-ended screw 67. The double-ended screw 67 is rotatably connected to the support plate 65. A hanging rod 68 is slidably connected inside the pressure frame 61. A pressure plate 69 is fixedly connected to the lower end of the lifting rod 68. A spring 610 is provided on the outer side of the lifting rod 68. One end of the spring 610 is fixedly connected to the pressure frame 61, and the other end of the spring 610 is fixedly connected to the pressure plate 69. By setting the spring 610, the pressure plate 69 is elastically pressed downward. The motor 66 drives the bidirectional screw 67 to rotate and the top plate 64 to make threaded movement, thereby changing the distance between the inclined rods 62 located on the outer side of the two top plates 64, thereby changing the position of the clamping plate 7. The cylinder 5 drives the pressure frame 61 to move and the inclined rods 62 to slide, thereby enabling the device to clamp and lift batteries of different lengths and widths. The spring 610 elastically presses the pressure plate 69 downward, thereby making the pressure plate 69 contact the battery, so that the battery is subjected to downward pressure. The eccentric wheel 9 supports the battery. When the battery shakes, the battery drives the eccentric wheel 9 to shift, so that the battery is pushed upward and cooperates with the spring 610, making it difficult for the battery to slide on the clamping plate 7, making the battery lifting more stable.

[0024] The specific implementation process of this utility model is as follows: In use, the device is moved to the outside of the battery, and the motor 66 is started. The motor 66 drives the bidirectional screw 67 to rotate. The rotation of the bidirectional screw 67 and the top plate 64 make a threaded movement, thereby causing the top plate 64 to move, changing the distance between the two top plates 64. The top plate 64 drives the inclined rod 62 to move, and the inclined rod 62 drives the clamping plate 7 to move. Then, the cylinder 5 is started, and the cylinder 5 drives the cylinder rod to extend. The cylinder rod drives the pressure frame 61 to move, causing the pressure frame 61 to slide outside the inclined rod 62. This causes the inclined rod 62 to drive the clamping plate 7 to move, so that the horizontal plate of the clamping plate 7 is inserted into the lower end of the battery. At this time, the bottom of the battery slides on the upper end of the guide wheel 8, and the bottom of the battery contacts the eccentric wheel 9. The bidirectional screw 67 is driven by the motor 66. The screw 67 rotates and the top plate 64 makes a threaded movement, which in turn changes the distance between the inclined rods 62 located on the outer side of the two top plates 64, thereby changing the position of the clamping plate 7. The cylinder 5 drives the pressure frame 61 to move and the inclined rods 62 to slide, so that the device can clamp and lift batteries of different lengths and widths. When the device as a whole comes into contact with the outside, the spring 610 elastically presses down the pressure plate 69, which then contacts the battery, putting downward pressure on the battery. The eccentric wheel 9 supports the battery. When the battery shakes, the battery drives the eccentric wheel 9 to shift, causing the battery to be pushed upward and cooperate with the spring 610, making it less likely for the battery to slide on the clamping plate 7, thus making the battery lifting more stable.
