Description

Technical Field

[0001] This invention relates to the field of hatch cover oil motor disassembly technology, and particularly to a portable disassembly device for a side-moving hatch cover oil motor. Background Technology

[0002] A bulk carrier is a commercial vessel specifically designed for transporting large quantities of unpackaged dry bulk cargo, primarily carrying granular or powdered goods such as ores, coal, grains, fertilizers, cement, and timber. Because its cargo does not require containers or liquid storage tanks, it is also called a "bulk cargo ship" or "dry bulk carrier." The cargo hatch cover is the sealing device for the cargo hatch openings of a bulk carrier, its core function being to isolate the cargo hold from the external environment. The hydraulic motor for the cargo hatch cover is the core actuator of the hydraulic drive system, responsible for converting hydraulic energy into mechanical energy to drive the cargo hatch cover to complete actions such as opening, closing, and locking / unlocking.

[0003] The hydraulic motors for the cargo hatch covers of bulk carriers are installed at the midpoint of the port and starboard sides of the hatch coaming. Each motor weighs 162 kg and is surrounded on three sides by the hatch coaming. When a hydraulic motor malfunctions and requires repair, it cannot be performed within this confined space. Therefore, the motor base and motor must first be moved sideways as a whole, and then the motor must be removed from the base and lowered onto the deck. There are 14 hydraulic motors on the main deck, widely distributed. Without a crane on board, this operation is difficult to complete; renting a dockside crane incurs additional costs.

[0004] Therefore, we propose a portable disassembly device for a side-moving hatch cover oil motor to solve the problems mentioned above. Summary of the Invention

[0005] Technical problems to be solved: To address the shortcomings of existing technologies, this invention provides a portable dismantling device for side-moving hatch cover hydraulic motors. The device has low manufacturing costs, a portable design that does not occupy shipboard space, and is easy to operate. It effectively solves the problem of not being able to lift hydraulic motors when there is no large crane on board, replacing the traditional solution that requires calling a shore-based large crane. It enables autonomous dynamic transfer of hydraulic motors, ensures maintenance efficiency, saves the cost of renting large cranes, and solves the technical problems mentioned in the background art.

[0006] Technical solution: To achieve the above objectives, the present invention provides the following technical solution: A portable dismantling device for a side-sliding hatch cover hydraulic motor includes a hydraulic motor support device and a hydraulic motor base. The hydraulic motor support device is installed on the hatch coaming, and the hydraulic motor body is installed on the hydraulic motor base. The hydraulic motor support device is used to support the hydraulic motor base after it has been removed. The hydraulic motor body is used to drive the hatch cover. Multiple sets of second lifting lugs are fixedly installed on the reverse side of the hydraulic motor base. The second lifting lugs are used to lower the hydraulic motor body to the main deck position. The hydraulic motor support device is fixedly connected to the hatch coaming by multiple sets of cotter pins. A set of first lifting lugs is fixedly installed on the outermost side of the hydraulic motor support device. The first lifting lugs are used to move the hydraulic motor base onto the hydraulic motor support device. After the hydraulic motor base and the hydraulic motor body are removed from their original installation positions, the portable hydraulic motor support device provides temporary support for the hydraulic motor body.

[0007] In one possible implementation, the hydraulic motor support device includes a first angle steel side frame, a second angle steel side frame, and a third angle steel side frame. The first angle steel side frame, the second angle steel side frame, and the third angle steel side frame together constitute the main frame structure. The first angle steel side frame and the second angle steel side frame are parallel to each other and perpendicular to each other. The second angle steel side frame and the third angle steel side frame are perpendicular to each other. The first angle steel side frame is welded and fixed by two sets of equilateral angle steels, and the second angle steel side frame is welded and fixed by two sets of equilateral angle steels. Multiple sets of reinforcing elbow plates are welded and fixed on both the first angle steel side frame and the second angle steel side frame. The overall device has low manufacturing cost, a portable design that does not occupy space on the ship, and is easy to operate.

[0008] In one possible implementation, a first angle steel brace is fixedly installed on one side of the lower end face of the main frame structure, and a second angle steel brace is fixedly installed on the other side of the lower end face of the main frame structure. Both the first and second angle steel braces are provided with openings. The first and second angle steel braces are auxiliary support components. Their inclined arrangement can enhance structural stability, optimize stress distribution, and resist instability and lateral loads.

[0009] In one possible implementation, a first ear plate is fixedly provided on one side of the lower end face of the first angle steel side frame, and a second ear plate is fixedly provided on one side of the lower end face of the second angle steel side frame. Both the first ear plate and the second ear plate have openings.

[0010] In one possible implementation, a first eye plate, a second eye plate, a third eye plate, and a fourth eye plate are fixedly provided on the hatch coaming, and each of the first eye plate, the second eye plate, the third eye plate, and the fourth eye plate has an opening.

[0011] In one possible implementation, the opening of the first angle steel brace is aligned with the opening of the first eye plate, the opening of the second angle steel brace is aligned with the opening of the second eye plate, the opening of the first ear plate is aligned with the opening of the third eye plate, and the opening of the second ear plate is aligned with the opening of the fourth eye plate. The alignment of the openings ensures that the connecting holes of the angle steel brace and the eye plate, and the ear plate and the eye plate are coaxial, so that the cotter pins inserted later are subjected to uniform force.

[0012] In one possible implementation, the four sets of cotter pins pass through the openings of the first angle steel brace and the first eye plate, the second angle steel brace and the second eye plate, the first ear plate and the third eye plate, and the second ear plate and the fourth eye plate, respectively, making the installation and removal of the cotter pins convenient.

[0013] In one possible implementation, the oil motor base has a mounting groove, and a frame is fixedly mounted on the oil motor base.

[0014] In one possible implementation, the second lifting lug is provided in three sets. By utilizing the spatial distribution characteristics of the three points, the load is transferred to the main structure of the base more evenly, reducing the risk of stress concentration.

[0015] In one possible implementation, sliding grooves are provided on both sides of the bottom surface of the oil motor base, and sliding strips are provided on the upper end surfaces of the first angle steel side frame and the second angle steel side frame. A set of sliding strips corresponds to a set of sliding grooves, and the sliding grooves and sliding strips are slidably connected. The slidable connection makes the translation process of the oil motor base smoother and avoids the phenomenon of displacement.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention consists of two parts: a portable hydraulic motor support device installed on the hatch coaming to support the hydraulic motor base after it has been moved out; and three sets of second lifting lugs installed on the reverse side of the hydraulic motor base to lower the hydraulic motor to the main deck position. The overall device has low manufacturing cost, a portable design that does not occupy shipboard space, and is easy to operate. It effectively solves the problem of not being able to lift hydraulic motors when there is no large crane on board, replacing the traditional solution that requires calling a shore-based large crane. It realizes the autonomous dynamic transfer of hydraulic motors, ensuring maintenance efficiency, saving the cost of renting large cranes, and reducing the overall cost of hydraulic motor maintenance. It is especially suitable for small and medium-sized ships or resource-constrained operating environments, and is applicable to hydraulic motor maintenance operations on all types of ships. When it is necessary to replace or repair the main body of the hydraulic motor, this device can quickly complete the entire process of disassembly, support, and transfer, especially on decks without large cranes or with narrow spaces, where its advantages are significant.

[0017] The slide bar of the hydraulic motor support device of the present invention is slidably connected to the slide groove of the hydraulic motor base, allowing the hydraulic motor base to move only in a preset direction, avoiding deviation and preventing the risk of collision caused by translational deviation. It ensures that the hydraulic motor base is accurately aligned with the support surface of the hydraulic motor support device, preventing unstable support due to positional deviation. The sliding connection makes the translation process of the hydraulic motor base smoother, especially suitable for small traction scenarios, reducing the labor intensity of operators.

[0021] This application provides a portable dismantling device for a side-moving hatch cover hydraulic motor. The device has low manufacturing cost, its portable design does not occupy shipboard space, and it is easy to operate. It effectively solves the problem of not being able to lift hydraulic motors when there is no large crane on board, replacing the traditional solution that requires calling a shore-based large crane. It realizes the autonomous dynamic transfer of the hydraulic motor, ensures maintenance efficiency, saves the cost of renting a large crane, and solves the technical problems mentioned in the background art.

[0022] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example 1: Please see Figure 1-10 The present invention provides a technical solution: a portable disassembly device for a side-moving hatch cover hydraulic motor, comprising a hydraulic motor support device 1 and a hydraulic motor base 2. The hydraulic motor support device 1 is installed on the hatch coaming 3, and the hydraulic motor body 4 is installed on the hydraulic motor base 2. The hydraulic motor support device 1 is used to support the hydraulic motor base 2 after it is removed, and the hydraulic motor body 4 is used to drive the hatch cover 5. Multiple sets of second lifting lugs 23 are fixedly arranged on the reverse side of the hydraulic motor base 2. The second lifting lugs 23 are used to lower the hydraulic motor body 4 to the main deck position. The hydraulic motor support device 1 and the hatch coaming 3 are fixedly connected by multiple sets of cotter pins 6. A set of first lifting lugs 18 is fixedly arranged on the outermost side of the hydraulic motor support device 1. The first lifting lugs 18 are used to move the hydraulic motor base 2 onto the hydraulic motor support device 1.

[0023] The overall portable dismantling device is divided into two parts: a portable hydraulic motor support device 1 installed on the hatch coaming 3 to support the hydraulic motor base 2 after it has been removed, and a second lifting lug 23 installed on the opposite side of the hydraulic motor base 2 to lower the hydraulic motor to the main deck position. After the hydraulic motor base 2 and the hydraulic motor body 4 are removed from their original installation positions, the portable hydraulic motor support device 1 provides temporary support for the hydraulic motor body 4 to ensure the stability of the hydraulic motor body 4 during dismantling and avoid the risk of direct landing or collision. The three sets of second lifting lugs 23 serve as lifting points, and in conjunction with small lifting equipment, such as a hand chain hoist, the hydraulic motor base 2 and the hydraulic motor body 4, which have been removed from their original positions, are slowly lowered to the main deck to complete the dismantling.

[0024] The hydraulic motor support device 1 and the second lifting lug 23 have clearly defined functions. During disassembly, the hydraulic motor support device 1 only needs to be pre-installed at the hatch coaming 3, the connection between the hydraulic motor body 4 and the external hydraulic pipeline needs to be removed, and the hydraulic motor body 4 can be directly supported after removal. During hoisting, the second lifting lug 23 can be used to complete the descent without relying on a large crane. The overall device has low manufacturing cost, a portable design that does not occupy ship space, and is easy to operate. It effectively solves the problem of not being able to hoist the hydraulic motor when there is no large crane on board, saving the hoisting cost during hydraulic motor maintenance. For scenarios where there is a lack of large cranes on ship decks, it replaces the traditional solution that requires calling a shore-based large crane, realizing the autonomous dynamic transfer of the hydraulic motor, ensuring maintenance efficiency, saving the cost of renting a large crane, and reducing the overall cost of hydraulic motor maintenance. It is especially suitable for small and medium-sized ships or resource-constrained operating environments, and is applicable to hydraulic motor maintenance operations on all types of ships. When it is necessary to replace or repair the hydraulic motor body 4, this device can quickly complete the entire process of disassembly, support, and transfer, especially on decks without large cranes or with narrow spaces, where its advantages are significant.

[0025] In some examples, the hydraulic motor support device 1 includes a first angle steel side frame 11, a second angle steel side frame 12, and a third angle steel side frame 13. These three side frames together form the main frame structure. The first angle steel side frame 11 and the second angle steel side frame 12 are parallel to each other, and the first angle steel side frame 11 and the third angle steel side frame 13 are perpendicular to each other. The second angle steel side frame 12 and the third angle steel side frame 13 are also perpendicular to each other. The first angle steel side frame 11 is formed by welding and fixing two sets of equilateral angle steels. The second angle steel side frame 12... It is formed by welding and fixing two sets of equilateral angle steels. Multiple sets of reinforcing elbow plates 19 are welded and fixed on the first angle steel side frame 11 and the second angle steel side frame 12. The multiple sets of reinforcing elbow plates 19 of the first angle steel side frame 11 are evenly distributed along the straight direction of the first angle steel side frame 11. The multiple sets of reinforcing elbow plates 19 of the second angle steel side frame 12 are evenly distributed along the straight direction of the second angle steel side frame 12. The multiple sets of reinforcing elbow plates 19 are welded and fixedly connected to the first angle steel side frame 11 and the multiple sets of reinforcing elbow plates 19 are welded and fixedly connected to the second angle steel side frame 12.

[0026] Angle steel is an L-shaped cross-section profile with a large moment of inertia and excellent bending and torsional resistance. When used as a supporting structure, it can effectively resist vertical and horizontal loads, reduce structural deformation, and ensure the overall rigidity and stability of the support system. Compared with solid steel or complex irregular-shaped components, angle steel can significantly reduce the structural self-weight and lower the load requirements on the foundation or connecting components while meeting strength requirements. Angle steel is a standardized industrial profile with mature production technology. Processing operations such as cutting, drilling, welding, and bending are simple, and batch prefabrication can be achieved, reducing the difficulty of on-site construction.

[0027] In some examples, a first angle steel brace 14 is fixedly installed on one side of the lower end face of the main frame structure, and a second angle steel brace 15 is fixedly installed on the other side of the lower end face of the main frame structure. Openings are provided on both the first angle steel brace 14 and the second angle steel brace 15.

[0028] The first angle steel brace 14 and the second angle steel brace 15 are auxiliary support components. Their inclined arrangement can enhance structural stability, optimize force distribution, and resist instability and lateral loads. The first angle steel brace 14 and the second angle steel brace 15 form an angle with the horizontal and vertical directions, which can decompose part of the vertical load into oblique tension or compression, which is borne by the support point and the foundation to avoid overload. When the main body 4 of the oil motor sways slightly, the first angle steel brace 14 and the second angle steel brace 15 can absorb energy through their own tensile and compressive deformation, reduce the sway amplitude of the main body of the support device, and ensure the stability of the temporary support after the oil motor base 2 is removed.

[0029] In some examples, a first ear plate 16 is fixedly provided on one side of the lower end face of the first angle steel side frame 11, and a second ear plate 17 is fixedly provided on one side of the lower end face of the second angle steel side frame 12. Both the first ear plate 16 and the second ear plate 17 are provided with openings, and the first ear plate 16 and the second ear plate 17 form a connection position.

[0030] In some examples, a first eye plate 31, a second eye plate 32, a third eye plate 33 and a fourth eye plate 34 are fixedly provided on the hatch coaming 3. The first eye plate 31, the second eye plate 32, the third eye plate 33 and the fourth eye plate 34 are all provided with openings, and the first eye plate 31, the second eye plate 32, the third eye plate 33 and the fourth eye plate 34 all form a connection position.

[0031] In some examples, the opening of the first angle steel brace 14 is aligned with the opening of the first eye plate 31, the opening of the second angle steel brace 15 is aligned with the opening of the second eye plate 32, the opening of the first ear plate 16 is aligned with the opening of the third eye plate 33, and the opening of the second ear plate 17 is aligned with the opening of the fourth eye plate 34. The opening alignment ensures that the connecting holes of the angle steel brace and the eye plate, and the ear plate and the eye plate are coaxial, so that the cotter pin 6 inserted later is subjected to uniform force, avoiding local stress concentration, premature deformation or even breakage of the brace due to eccentric load. During the pre-assembly stage, the opening alignment can quickly position each component and reduce the on-site debugging time.

[0032] In some examples, four sets of cotter pins 6 pass through the openings of the first angle steel brace 14 and the first eye plate 31, the second angle steel brace 15 and the second eye plate 32, the first ear plate 16 and the third eye plate 33, and the second ear plate 17 and the fourth eye plate 34, respectively. The cotter pins 6 are easy to install and remove, which meets the convenience requirements of the portable oil motor support device 1.

[0033] In some examples, the oil motor base 2 has a mounting groove 21, a frame 22 is fixedly installed on the oil motor base 2, and the oil motor body 4 is installed on the oil motor base 2.

[0034] In some examples, three sets of second lifting lugs 23 are provided. The hydraulic motor base 2 and the hydraulic motor body 4 themselves have weight, which is transferred through the second lifting lugs 23 during hoisting. The three sets of second lifting lugs 23 achieve multi-point load bearing, avoiding concentrated stress on a single or double lifting lug, significantly reducing the stress level of a single lifting lug, and preventing lug breakage, base deformation, or even equipment damage due to localized overload. Utilizing the spatial distribution characteristics of the three points, the load is transferred more evenly to the base structure, reducing the risk of stress concentration and extending the service life of the lifting lugs and base. The three sets of second lifting lugs 23 form a stable support triangle in space, which can effectively suppress the tilting and swaying tendency of the base during hoisting, greatly improving the balance of the hoisting process. Three-point hoisting can more accurately match the center of gravity of the equipment, ensuring operational safety. If one set of lifting lugs fails temporarily due to an accident, the remaining two sets of lifting lugs can still bear part of the load, buying time for emergency response and preventing the direct fall of the equipment. At the same time, the three sets of lifting lugs provide multi-dimensional hoisting options, and the hoisting points can be flexibly adjusted according to the site conditions to adapt to complex conditions such as narrow spaces and irregular sites.

[0035] By adopting the above technical solution: The overall portable dismantling device consists of two parts: a portable hydraulic motor support device 1 installed on the hatch coaming 3 to support the hydraulic motor base 2 after it has been removed, and a second lifting lug 23 installed on the opposite side of the hydraulic motor base 2 to lower the hydraulic motor to the main deck position. The overall device has low manufacturing cost, a portable design that does not occupy ship space, and is easy to operate. It effectively solves the problem of not being able to lift hydraulic motors when there are no large cranes on board, replacing the traditional solution that requires calling a shore-based large crane. It realizes the autonomous dynamic transfer of hydraulic motors, ensures maintenance efficiency, saves the cost of renting large cranes, and reduces the overall cost of hydraulic motor maintenance.

[0036] Example 2: Based on Embodiment 1, this embodiment introduces the specific structure of the oil motor base 2 and the oil motor support device 1 in a portable disassembly device for a side-moving hatch oil motor. Slide grooves 24 are provided on both sides of the bottom surface of the oil motor base 2. Slide strips 111 are provided on the upper end surfaces of the first angle steel side frame 11 and the second angle steel side frame 12. A set of slide strips 111 corresponds to a set of slide grooves 24, and the slide grooves 24 and slide strips 111 are slidably connected.

[0037] After the hydraulic motor base 2 is removed from its original installation position, it needs to be moved horizontally onto the hydraulic motor support device 1. The hydraulic motor support device 1 provides temporary support for the hydraulic motor body 4. The cooperation between the slide bar 111 and the slide groove 24 only allows the hydraulic motor base 2 to move horizontally in a preset direction, avoiding any deviation and preventing the risk of collision caused by the horizontal deviation. This ensures that the hydraulic motor base 2 is accurately aligned with the support surface of the hydraulic motor support device 1, preventing unstable support due to positional deviation. The sliding connection makes the horizontal movement of the hydraulic motor base 2 smoother, especially suitable for small traction scenarios, reducing the labor intensity of operators.

[0038] The slide bar 111 of the oil motor support device 1 is embedded in the slide groove 24 of the oil motor base 2. The oil motor base 2 is accurately positioned and temporarily fixed through sliding connection, ensuring that the oil motor base 2 does not shake during the support process. When hoisting, the slide groove 24 of the oil motor base 2 can be disengaged from the slide bar 111 of the oil motor support device 1, without affecting the normal hoisting.

[0039] When the maintenance is completed and the hydraulic motor body 4 is reinstalled, the sliding groove 24 of the hydraulic motor base 2 can be aligned with the sliding bar 111 of the hydraulic motor support device 1. The sliding groove 24 of the hydraulic motor base 2 slides along the sliding bar 111 of the hydraulic motor support device 1, forcing the hydraulic motor base 2 to move along the preset straight line direction, ensuring that the hydraulic motor base 2 is accurately connected with the original installation position, and ensuring installation accuracy.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
