Description

Technical Field

[0001] This utility model relates to the field of ship repair equipment technology, and in particular to a ship balance hoisting and repair device. Background Technology

[0002] With the rapid development of the global shipping industry, ship maintenance has become a crucial aspect of ensuring navigational safety and service quality. However, in actual maintenance processes, due to the complexity of ship structures, especially when replacing large equipment and components, hoisting equipment is typically required to lift the equipment and components that need repair.

[0003] In the existing technology, the traditional hoisting equipment mainly includes manual hoist hoisting and hydraulic lifting platform assisted hoisting. Manual hoist hoist hoisting is widely used in the maintenance of small equipment because it is simple and easy to implement. However, since manual hoist hoist hoisting adopts a single-arm hoisting structure, it is not powerful enough for heavy and large equipment components, has poor stability, and is prone to safety hazards.

[0004] Therefore, a ship balance lifting and maintenance device is proposed. Utility Model Content

[0005] In order to improve the existing single-arm hoisting structure, which is inadequate for heavy and large equipment components, has poor stability, and is prone to safety hazards, this utility model provides a ship balance hoisting and maintenance device.

[0006] This utility model provides a ship balance lifting and maintenance device, which adopts the following technical solution:

[0007] A ship balance lifting and maintenance device includes a frame, an electric hoist, a first adjustment mechanism, and a second adjustment mechanism. The frame includes two parallel crossbeams, and two parallel longitudinal beams are slidably installed on the crossbeams. Lifting seats are slidably installed on both longitudinal beams, and electric hoists are fixedly installed at the bottom of both lifting seats.

[0008] The first adjustment mechanism includes a transverse double helical screw rotatably installed in a crossbeam. Two symmetrically distributed support seats are threaded onto the transverse double helical screw. Both ends of the longitudinal beam are fixedly installed on the support seats. A first motor is fixedly installed at one end of one of the crossbeams. The output end of the first motor is fixedly connected to one of the transverse double helical screws. The ends of the two transverse double helical screws away from the first motor are linked by a synchronization component.

[0009] The second adjustment mechanism includes a longitudinal screw rotatably mounted inside a longitudinal beam, a lifting seat sleeved on the longitudinal screw and threadedly connected to the longitudinal screw, and a slide rail fixedly mounted on one of the crossbeams, the slide rail containing a drive assembly for driving the longitudinal screw to rotate.

[0010] By adopting the above technical solution and setting up two lifting seats and electric hoists, heavy and large equipment components can be double-lifted, improving the stability of equipment components during maintenance and reducing safety hazards. Through the first adjustment mechanism, when the distance between the two electric hoists needs to be adjusted, the first motor can be started to drive one of the transverse double-helix screws to rotate. This causes the two transverse double-helix screws to move synchronously through a synchronization component, driving two support seats on the same crossbeam to move relative to or opposite to each other along the beam. This causes the support seats to slide along the longitudinal beam, thereby adjusting the distance between the two longitudinal beams. This facilitates the lifting of equipment components of different sizes and improves the flexibility of use. The synchronization component also protects the synchronization pulley and belt. When one of the transverse double-helix screws drives the synchronization pulley to rotate, the two synchronization pulleys rotate synchronously through the synchronization belt.

[0011] Optionally, columns are fixedly connected to the bottom of both ends of the crossbeam, and a reinforcing rod is fixedly installed between the two columns on the same side.

[0012] By adopting the above technical solution, the columns can be strongly connected, thus improving the overall stability of the frame.

[0013] Optionally, a reinforcing diagonal brace is fixedly installed between the crossbeam and the column.

[0014] By adopting the above technical solutions, the beams and columns can be connected and strengthened, thereby improving the overall stability of the frame.

[0015] Optionally, the synchronization component includes a synchronization pulley fixedly installed at the end of a transverse double helical screw, and the two synchronization pulleys are linked by a synchronization belt.

[0016] By adopting the above technical solution, when one of the transverse double helical screws drives the synchronous pulley to rotate, the two synchronous pulleys will rotate synchronously through the synchronous belt.

[0017] Optionally, a housing is fixedly installed at the end of the crossbeam away from the first motor, and the synchronous pulley and synchronous belt are disposed inside the housing.

[0018] By adopting the above technical solution, the outer casing can protect the timing pulley and timing belt.

[0019] Optionally, the drive assembly includes a crossbar rotatably mounted in a slide rail, a second motor for driving the crossbar to rotate is fixedly mounted at one end of the slide rail, a main gear is rotatably mounted at one end of the longitudinal beam, the main gear is slidably sleeved on the crossbar, and a driven gear that meshes with the main gear is fixedly mounted at one end of the longitudinal screw.

[0020] By adopting the above technical solution, the second motor can be started to drive the crossbar to rotate, which in turn drives the main gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the longitudinal screw to rotate.

[0021] Optionally, the surface of the crossbar is provided with guide bars, and the shaft of the main gear is provided with a guide groove that matches the guide bars.

[0022] By adopting the above technical solution, the crossbar can drive the main gear to rotate, while the longitudinal beam can also drive the main gear to slide along the crossbar.

[0023] Optionally, a clearance opening is provided on the side of the longitudinal beam away from the main gear.

[0024] By adopting the above technical solution, contact between the longitudinal beam and the transverse bar can be avoided.

[0025] In summary, this utility model has the following beneficial effects:

[0026] 1. By setting up two lifting bases and an electric hoist, this utility model can double-lift heavy and large equipment components, improving the stability of equipment components during maintenance and reducing safety hazards.

[0027] 2. By setting up the first adjustment mechanism, when it is necessary to adjust the distance between the two electric hoists, the first motor can be started to drive one of the transverse double helical screws to rotate. The two transverse double helical screws are then linked synchronously through the synchronization component. This causes the transverse double helical screws to drive the two support seats on the same crossbeam to move relative to or opposite to each other along the beam. The support seats then drive the longitudinal beam to slide, thereby adjusting the distance between the two longitudinal beams. This facilitates the hoisting of equipment components of different sizes and improves the flexibility of use. Attached Figure Description

Detailed Implementation

[0034] The following description, in conjunction with the embodiments of this utility model, includes appendices. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Please refer to Figure 1-2 A ship balancing hoisting and maintenance device includes a frame 1, an electric hoist 2, a first adjustment mechanism 3, and a second adjustment mechanism 4. The frame 1 includes two parallel crossbeams 11, and two parallel longitudinal beams 12 are slidably installed on the crossbeams 11. Each of the two longitudinal beams 12 is slidably installed with a hoisting seat 13, and an electric hoist 2 is fixedly installed at the bottom of each hoisting seat 13. By setting up two hoisting seats 13 and electric hoists 2, when facing heavy and large equipment components, double hoisting can be performed on the equipment components, which improves the stability of the equipment components during maintenance and reduces safety hazards.

[0036] The bottom of both ends of the crossbeam 11 is fixedly connected to columns 14, and a reinforcing rod 15 is fixedly installed between two columns 14 on the same side. The reinforcing rod 15 provides a strong connection between the columns 14, improving the overall stability of the frame 1. A reinforcing diagonal brace 16 is fixedly installed between the crossbeam 11 and the columns 14. The reinforcing diagonal brace 16 strengthens the connection between the crossbeam 11 and the columns 14, improving the overall stability of the frame 1.

[0037] Reference Figure 1 and Figure 2The first adjusting mechanism 3 includes a transverse double helix screw 31 rotatably mounted inside the crossbeam 11. The surface of the transverse double helix screw 31 is provided with two completely opposite threads. Two symmetrically distributed support seats 32 are threadedly connected to the transverse double helix screw 31. Both ends of the longitudinal beam 12 are fixedly mounted on the support seats 32. A first motor 33 is fixedly mounted on one end of one of the crossbeams 11. The output end of the first motor 33 is fixedly connected to one of the transverse double helix screws 31. The ends of the two transverse double helix screws 31 away from the first motor 33 are connected by a synchronization component 34. The first adjustment mechanism 3 allows the first motor 33 to be started to drive one of the transverse double helical screws 31 to rotate when the distance between the two electric hoists 2 needs to be adjusted. This causes the two transverse double helical screws 31 to be synchronously linked through the synchronization component 34. The transverse double helical screws 31 drive the two support seats 32 on the same crossbeam 11 to move relative to or opposite to each other along the beam 11. This causes the support seats 32 to drive the longitudinal beam 12 to slide, thereby adjusting the distance between the two longitudinal beams 12. This facilitates the hoisting of equipment components of different sizes and improves the flexibility of use.

[0038] Specifically, the synchronization component 34 includes a synchronization wheel 341 fixedly installed at the end of the transverse double helical screw 31. The two synchronization wheels 341 are linked by a synchronization belt 342. A housing 343 is fixedly installed at the end of the crossbeam 11 away from the first motor 33. The synchronization wheel 341 and the synchronization belt 342 are arranged inside the housing 343. Through the arrangement of the synchronization component 34, the housing 343 can protect the synchronization wheel 341 and the synchronization belt 342. When one of the transverse double helical screws 31 drives the synchronization wheel 341 to rotate, the two synchronization wheels 341 will rotate synchronously through the synchronization belt 342.

[0039] Reference Figures 1-3 The second adjustment mechanism 4 includes a longitudinal screw 41 rotatably installed in the longitudinal beam 12, and a lifting seat 13 sleeved on the longitudinal screw 41 and threadedly connected to the longitudinal screw 41. A slide rail 42 is fixedly installed on one of the cross beams 11. The slide rail 42 is provided with a drive assembly 43 for driving the longitudinal screw 41 to rotate. With the setting of the second adjustment mechanism 4, when it is necessary to adjust the position of the electric hoist 2, the drive assembly 43 can be activated to drive the longitudinal screw 41 to rotate, so that the longitudinal screw 41 drives the lifting seat 13 to slide along the longitudinal beam 12, thereby adjusting the position of the electric hoist 2.

[0040] Specifically, the drive assembly 43 includes a crossbar 431 rotatably mounted in a slide rail 42. A second motor 432 for driving the crossbar 431 to rotate is fixedly mounted at one end of the slide rail 42. A main gear 433 is rotatably mounted at one end of the longitudinal beam 12. The main gear 433 is slidably sleeved on the crossbar 431. A driven gear 434 that meshes with the main gear 433 is fixedly mounted at one end of the longitudinal screw 41. By setting up the drive assembly 43, the second motor 432 can be started to drive the crossbar 431 to rotate, which in turn drives the main gear 433 to rotate, which in turn drives the driven gear 434 to rotate, which in turn drives the longitudinal screw 41 to rotate.

[0041] Reference Figures 2-4 The surface of the crossbar 431 is provided with guide bars, and the shaft of the main gear 433 has a guide groove 435 that matches the guide bars. Through the cooperation between the guide bars and the guide groove 435, the crossbar 431 can drive the main gear 433 to rotate, while also ensuring that the longitudinal beam 12 can drive the main gear 433 to slide along the crossbar 431. A clearance opening is provided on the side of the longitudinal beam 12 away from the main gear 433, which can prevent the longitudinal beam 12 from contacting the crossbar 431.

[0042] The implementation principle of this utility model is as follows: By setting two hoisting seats 13 and electric hoists 2, when dealing with heavy and large equipment components, double hoisting can be performed on the equipment components, improving the stability of the equipment components during maintenance and reducing safety hazards. Through the setting of the first adjustment mechanism 3, when it is necessary to adjust the distance between the two electric hoists 2, the first motor 33 can be started to drive one of the transverse double helical screws 31 to rotate, so that the two transverse double helical screws 31 are synchronously linked through the synchronization component 34, so that the transverse double helical screws 31 drive the two support seats 32 on the same crossbeam 11 along the beam. The relative or opposite movement of the support base 32 causes the longitudinal beam 12 to slide, thereby adjusting the distance between the two longitudinal beams 12. This facilitates the hoisting of equipment components of different sizes and improves the flexibility of use. Through the setting of the second adjustment mechanism 4, when it is necessary to adjust the position of the electric hoist 2, the second motor 432 can be started to drive the crossbar 431 to rotate, which in turn drives the main gear 433 to rotate, which in turn drives the driven gear 434 to rotate, which in turn drives the longitudinal screw 41 to rotate, which in turn drives the hoisting base 13 to slide along the longitudinal beam 12, thereby adjusting the position of the electric hoist 2.

[0043] The above description is merely 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.
