[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0018] Reference Figures 1-3This utility model provides an embodiment of a device for lifting marine electrical machinery, comprising a fixed frame 1 and a lifting device 2. The lifting device 2 is fixedly connected to the top outer wall of the fixed frame 1. A hook assembly 3 is fixedly connected to the output end of the lifting device 2. The hook assembly 3 is used to hook the electrical machinery and is a key component connecting the lifting device 2 and the object being lifted, enabling the transmission of power from the lifting device 2 to the object being lifted. An anti-fall mechanism 4 is provided on the fixed frame 1, and an adjustment mechanism 5 is provided on the anti-fall mechanism 4. The anti-fall mechanism 4 includes a slide rail 41, which is opened on the front inner wall of the fixed frame 1. Sliding frames 42 are slidably connected to the left and right inner walls of the slide rail 41. A fall arrestor 43 is fixedly connected to the front outer wall of the sliding frame 42. A movable plate 44 is slidably connected to the rear inner wall of the sliding frame 42. A locking plate 45 is fixedly connected to the left outer wall of the movable plate 44. The locking plate 45 can cooperate with the locking groove on the slide rail 41. During normal lifting, it can retract to allow the sliding frame 42 to move smoothly. During a fall, it is locked into the locking groove to achieve a limit. An arc-shaped surface 46 is opened on the top outer wall of the locking plate 45. A compression spring 47 is fixedly connected to the left outer wall of the movable plate 44. A telescopic hydraulic cylinder 48 is fixedly connected to the right inner wall of the sliding frame 42. The telescopic hydraulic cylinder 48 can provide power to push the movable plate 44 to move to the right, so that the locking plate 45 retracts, making it easier for the sliding frame 42 to move downward.
[0019] Reference Figures 2-4 A wear-resistant sleeve is fixedly connected to the outer side wall of the card plate 45. The wear-resistant sleeve can reduce the frictional wear between the card plate 45 and the card slot and extend the service life of the card plate 45. A card slot is opened on the inner right side wall of the slide rail 41. The card slot cooperates with the card plate 45 and can limit the card plate 45 when the electrical and mechanical equipment falls, preventing the sliding frame 42 from falling further. The outer side walls of the card slot and the arc surface 46 are coated with lubricating oil. The lubricating oil can reduce the friction between the card slot and the arc surface 46, making the relative movement of the card plate 45 smoother when it contacts the card slot. The card plate 45 passes through the outer right side wall of the sliding frame 42. The end of the compression spring 47 away from the movable plate 44 is fixedly connected to the inner left side wall of the sliding frame 42. The telescopic hydraulic cylinder 48 contacts the outer right side wall of the movable plate 44. There are two sliding frames 42. The two sliding frames 42 are fixedly connected to the outer rear side wall of the anti-fall frame 43 respectively.
[0020] Reference Figures 3-4The adjustment mechanism 5 includes an adjustment plate 51, which is slidably connected to the top inner wall of the fall arrestor 43. A pin 52 passes through the top inner wall of the adjustment plate 51, and the pin 52 can be inserted into the adjustment hole 522 to fix the adjustment plate 51 in a specific position of the fall arrestor 43, preventing it from sliding freely. An adjustment hole 522 is provided on the bottom inner wall of the fall arrestor 43. A sliding plate 53 is slidably connected to the top inner wall of the adjustment plate 51. A mechanical placement plate 54 is fixedly connected to the top outer wall of the sliding plate 53. The mechanical placement plate 54 is used to place electrical mechanical equipment and provide it with a stable bearing surface. A threaded nail 55 is threadedly connected to the right inner wall of the sliding plate 53. The threaded nail 55 can be rotated to tighten the adjustment plate 51, fixing the sliding plate 53 in a specific position of the adjustment plate 51, ensuring... To ensure stability after left and right adjustment, the pin 52 penetrates the inner wall of the inner ring of the adjustment hole 522. There are several adjustment holes 522, which are sequentially opened on the bottom inner wall of the anti-fall frame 43. These adjustment holes 522 are distributed in different positions to provide more fixing points for the adjustment plate 51, meeting different front and rear adjustment needs. The threaded nail 55 penetrates the front inner wall of the adjustment plate 51. The top inner wall of the mechanical placement plate 54 is fitted with a retaining ring frame 56, which can block the electrical and mechanical equipment placed on the mechanical placement plate 54 to prevent it from slipping during movement. The top inner wall of the mechanical placement plate 54 is provided with a serial port 57, which can be used to thread binding straps, etc., to firmly fix the electrical and mechanical equipment on the mechanical placement plate 54.
[0021] Working principle: The electromechanical equipment is placed on the mechanical placement plate 54 and tied to it. Then, the hook assembly 3 is hooked onto the electromechanical equipment. The lifting device 2 is then activated, causing the electromechanical equipment and the mechanical placement plate 54 to move upwards. The movement of the mechanical placement plate 54 causes the adjusting plate 51 and the anti-fall frame 43 to move. The movement of the anti-fall frame 43 causes the sliding frame 42 to move. The movement of the sliding frame 42 causes the locking plate 45 to move. The movement of the locking plate 45 causes the arc-shaped surface 46 to contact the locking groove and compress the locking plate 45. When the locking plate 45 retracts, the sliding frame 42 moves upwards in the slide rail 41. In the event of a malfunction of the lifting device 2, the electromechanical equipment... When the pneumatic mechanical equipment falls downwards, the clamping plate 45 engages with the nearest clamping slot to limit the movement, thus supporting the electrical mechanical equipment on the mechanical placement plate 54 platform to prevent it from falling. At the same time, when it is necessary to descend, the telescopic hydraulic cylinder 48 is activated to push the movable plate 44, causing the movable plate 44 to move and drive the clamping plate 45 to retract, so that the sliding frame 42 contacts the limit and falls. At the same time, when the electrical mechanical equipment is lifted, if it is necessary to adjust its front-back, left-right position, or right-back position, the adjusting plate 51 is adjusted by pulling the pin 52, and the inner wall of the sliding plate 53 is pulled out by rotating the threaded nail 55. Then, the mechanical placement plate 54 is moved to the rightmost position for adjustment.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
