Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, and in particular to a hoisting tool and hoisting equipment. Background Technology

[0002] As a core component of marine diesel engines, the cylinder block involves multiple lifting operations during its manufacturing and assembly process, including machining, finishing, and overall engine installation. However, cylinder blocks are typically box-shaped structures with complex shapes, massive weights (often reaching hundreds of tons), and lack of dedicated lifting lugs or points, which presents significant technical challenges to their lifting process.

[0003] Currently, the industry lacks standardized lifting tools for this component. Existing lifting operations generally rely on wire ropes threaded through cylinder liner bores and gland holes for load-bearing lifting. As precision mating surfaces, cylinder liner bores and gland holes have extremely high requirements for surface roughness and geometric tolerances. Direct threading and friction of the wire rope can easily cause scratches and wear on the bore walls, thus affecting subsequent assembly accuracy and even causing stress concentration. Secondly, with the wire rope only threaded through cylinder liner bores and gland holes, even slight swaying during lifting can cause the wire rope to move relative to the cylinder block, causing slippage of the stress point, resulting in poor lifting stability and potential safety hazards from impact loads.

[0004] Therefore, there is an urgent need for a hoisting tool and hoisting equipment to solve the above problems. Summary of the Invention

[0005] The first objective of this invention is to provide a lifting tool to solve the problems in the prior art where the cylinder liner bore wall and the gland bore wall are easily scratched when lifting cylinder bodies, affecting subsequent assembly accuracy, as well as the poor lifting stability and the tendency to generate impact loads.

[0006] The second objective of this invention is to provide a hoisting device that can prevent damage to the cylinder liner bore and gland bore when hoisting the cylinder body and improve hoisting stability.

[0007] To achieve this objective, the present invention adopts the following technical solution: A hoisting tool is used to hoist a cylinder body, the cylinder body being placed on a placement platform. The cylinder body has a first pipe perforation group and a second pipe perforation group. Both the first and second pipe perforation groups include a plurality of pipe perforations evenly spaced. The hoisting tool includes a hoisting component and a plurality of through-hole structures. Each through-hole structure includes a through-hole body and abutment members located at both ends of the through-hole body. Any through-hole body and the corresponding two abutment members are detachably connected. Any through-hole body can pass through any of the pipe perforations. The plurality of abutment members can abut against the cylinder body. The plurality of abutment members are detachably connected to the hoisting component. The hoisting tool has a first working state and a second working state. The first working state is used to hoist the cylinder body in the first position state, and the second working state is used to hoist the cylinder body in the second position state. When the hoisting tool is in the first working state, a portion of the main body is inserted through a portion of the pipe perforation in the first pipe perforation group and the corresponding plurality of abutting parts are connected to the hoisting assembly, so that the cylinder body maintains the first position state. When the hoisting tool is in the second working state, multiple penetration bodies are respectively inserted into a portion of the pipe holes of the first pipe hole group and a portion of the pipe holes of the second pipe hole group, and multiple abutment members located on the side of the cylinder body away from the placement platform are connected to the hoisting assembly so that the cylinder body maintains the second position state.

[0008] In some embodiments, four through-hole structures are provided. When the hoisting tool is in the first working state, two of the through-hole bodies are respectively inserted through two of the pipe holes in the first pipe hole group, and the four corresponding abutment members are all connected to the hoisting assembly. The centroids of the two through-hole bodies are equidistant from the centroids of the cylinder body. When the hoisting tool is in the second working state, the four through-hole bodies are respectively inserted through two of the pipe holes in the first pipe hole group and two of the pipe holes in the second pipe hole group. The four abutment members located on the same side of the cylinder body away from the placement platform are all connected to the hoisting assembly. The centroids of the four through-hole bodies are equidistant from the centroids of the cylinder body.

[0009] In some embodiments, the hoisting assembly includes a hook, a connecting rope, and a plurality of intermediate connectors, wherein the connecting rope is attached to the hook, and the abutment is detachably connected to the connecting rope via the intermediate connectors.

[0010] In some embodiments, the abutment includes a detachably connected sleeve and a lifting lug. The side of the sleeve away from the lifting lug is detachably connected to the inserting body, and the side of the lifting lug away from the sleeve is detachably connected to the hoisting assembly. The sleeve can abut against the cylinder body, and the lifting lug and the connecting rope are detachably connected through the intermediate connector.

[0011] In some embodiments, the sleeve includes a connected cylindrical body and an abutment plate, the inner wall of the cylindrical body is provided with threads, and the ends of the lifting lug and the through-body are both threadedly connected to the cylindrical body.

[0012] In some embodiments, the intermediate connector includes a threaded clip and a connecting pin, the connecting pin being able to pass through the clip and the lug on the side away from the sleeve.

[0013] In some embodiments, the hoisting assembly includes a plurality of connecting ropes, the middle of which is attached to the hook, and both ends of the connecting ropes are detachably connected to the intermediate connector.

[0014] In some embodiments, four of the threading structures are provided, and the hoisting assembly includes two of the connecting ropes, with the middle of each of the two connecting ropes being attached to the hook.

[0015] In some embodiments, the hook includes a main body, a first connecting hook, a second connecting hook, and a third connecting hook. The first connecting hook is located at one end of the main body and is used to connect an external drive device. The second connecting hook and the third connecting hook are both located at the other end of the main body. One connecting rope is attached to the second connecting hook, and the other connecting rope is attached to the third connecting hook.

[0016] A hoisting device includes a crane and the hoisting tool, wherein the crane and the hoisting assembly are detachably connected.

[0017] The beneficial effects of this invention are: This invention provides a hoisting tool for hoisting a cylinder body. The cylinder body is placed on a placement platform. The cylinder body has a first group of through holes and a second group of through holes. Both the first and second groups of through holes include multiple through holes evenly spaced. The hoisting tool includes a hoisting component and multiple through-hole structures. Each through-hole structure includes a through-hole body and abutment members located at both ends of the through-hole body. Any through-hole body and its corresponding two abutment members are detachably connected. Any through-hole body can pass through any through hole, and the multiple abutment members can abut against the cylinder body. The multiple abutment members are detachably connected to the hoisting component. The hoisting tool has a first working state and a second working state. The first working state is used to hoist the cylinder body in a first position state, and the second working state is used to hoist the cylinder body in a second position state. When the hoisting tool is in the first working state, part of the through-hole body passes through part of the through holes in the first group of through holes, and the corresponding multiple abutment members are connected to the hoisting component to keep the cylinder body in the first position state. When the hoisting tool is in its second working state, multiple through-body components are respectively inserted through parts of the pipe holes in the first pipe hole group and parts of the pipe hole group in the second pipe hole group. Multiple abutment components located on the side of the cylinder body away from the placement platform are connected to the hoisting assembly to maintain the cylinder body in its second position. Through this configuration, different working states of the hoisting tool are used to hoist cylinder bodies in different positions, preventing the cylinder body from tipping over during hoisting. During hoisting, because the through-body components can pass through the pipe holes of the cylinder body, the abutment components at both ends of the through-body components can abut against the cylinder body. The through-body components will not move along their own axial direction, and the abutment components can stably abut against the cylinder body. The hoisting assembly can connect multiple abutment components to simultaneously connect multiple through-body structures, facilitating the hoisting of the cylinder body. This eliminates the need for the cylinder body's cylinder liner holes and gland holes, preventing wear on the cylinder liner hole and gland hole walls caused by wire ropes winding through them, thus ensuring subsequent assembly accuracy. Meanwhile, the two abutting parts corresponding to any one of the penetrating main bodies abut against the cylinder body, meaning that the two abutting parts corresponding to any one of the penetrating main bodies are in a clamping state against the cylinder body. The multiple penetrating structures are relatively stable relative to the cylinder body, ensuring the stability of the hoisting tool during the hoisting process, reducing the risk of generating impact loads, and ensuring the safety of hoisting.

[0018] The present invention also provides a hoisting device, including a crane and the above-mentioned hoisting tool. The crane and the hoisting component are detachably connected. When hoisting the cylinder body, the cylinder liner bore and the grate bore can be avoided from being damaged, and the hoisting stability can be improved. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0026] This embodiment provides a hoisting tool for hoisting cylinder blocks, which avoids wear on the cylinder liner bore walls and gland bore walls, ensuring the stability of the hoisting tool during the hoisting process, reducing the risk of impact loads, and ensuring the safety of hoisting.

[0027] It should be noted that in a diesel engine cylinder block, the cylinder liner bore is where the cylinder liner is installed. Its inner wall precision is extremely high (usually to ensure the roundness and perpendicularity of the cylinder liner). The grate bore refers to the bolt holes or locating holes around the cylinder liner used to install intake / exhaust grilles or scavenging box sealing structures; these are typically threaded holes or precision smooth holes. The pipe perforation refers to a cast and machined circular channel through the cylinder block for installing pipe perforation bolts. It has thick and robust walls and does not involve precision fitting. It is used to connect the cylinder block, frame, and engine base, forming a single unit. The cylinder block has a first pipe perforation group and a second pipe perforation group, which are arranged parallel to each other and located on both sides of multiple cylinder liner bores. Both the first and second pipe perforation groups include multiple pipe perforations spaced evenly apart, with the axial direction of the pipe perforations parallel to the axial direction of the cylinder liner bores.

[0028] It should also be noted that before hoisting the cylinder body, it may be in either a first or second position. In the first position, the axial directions of the multiple perforations in both the first and second perforation groups are parallel to the placement platform, with the first perforation group positioned above the second. In the second position, the axial directions of the multiple perforations in both groups are perpendicular to the placement platform. In other words, the first position refers to the cylinder body being horizontally placed, and the second position refers to it being vertically placed. The placement platform refers to the location where the cylinder body is placed; it can be the ground, a horizontal platform, or a workbench. Typically, there are wooden supports on the placement platform to facilitate the installation of hoisting equipment.

[0029] In this embodiment, as Figures 1-9As shown, the hoisting tool includes a hoisting assembly 1 and multiple through-hole structures 2. Each through-hole structure 2 includes a through-hole body 21 and abutment members 22 located at both ends of the through-hole body 21. Each through-hole body 21 and its corresponding two abutment members 22 are detachably connected. Each through-hole body 21 can pass through any pipe hole, and the multiple abutment members 22 can abut against the cylinder body 100. The multiple abutment members 22 are detachably connected to the hoisting assembly 1. The hoisting tool has a first working state and a second working state. The first working state is used to hoist the cylinder body 100 in the first position state, and the second working state is used to hoist the cylinder body 100 in the second position state. When the hoisting tool is in the first working state, part of the through-hole body 21 passes through part of the pipe holes in the first pipe hole group 101, and the corresponding multiple abutment members 22 are connected to the hoisting assembly 1 to keep the cylinder body 100 in the first position state. When the hoisting tool is in the second working state, multiple through-body 21s are respectively inserted through part of the pipe holes of the first pipe hole group 101 and part of the pipe holes of the second pipe hole group 102, and multiple abutting parts 22 located on the side of the cylinder body 100 away from the placement platform are connected to the hoisting assembly 1 so that the cylinder body 100 maintains the second position state.

[0030] It is understandable that by setting the first working state and the second working state, when the cylinder body 100 is in the first position state, the cylinder body 100 is lifted using the first working state of the lifting tool. Part of the main body 21 passes through the pipe holes in the first pipe hole group 101 and the corresponding abutment 22 is connected to the lifting component 1. At this time, the axis of the pipe hole is parallel to the placement platform (ground), and the axis of the part of the main body 21 is also parallel to the ground. The first pipe hole group 101 is located above the second pipe hole group 102. During the lifting process, specifically at the beginning of lifting the cylinder, the cylinder body 100 will not flip, keeping the cylinder body 100 in the first position state and ensuring the stability of the cylinder body 100 during lifting. When the cylinder body 100 is in the second position, the cylinder body 100 is lifted using the second working state of the lifting tool. Multiple through-body parts 21 are respectively inserted through parts of the pipe holes in the first pipe hole group 101 and parts of the pipe hole group 102. Multiple abutment parts 22 located on the side of the cylinder body 100 away from the placement platform are connected to the lifting assembly 1. When the cylinder body 100 is lifted in this state, it will not overturn, maintaining the second position and ensuring stability during lifting. In other words, the lifting tool has both a first and a second working state, enabling stable lifting of the cylinder body 100 in different positions and avoiding situations prone to impact loads.

[0031] During hoisting, the main body 21 can pass through the pipe hole of the cylinder body 100. The abutment 22 located at both ends of the main body 21 can abut against the cylinder body 100. The main body 21 will not move along its own axis. The abutment 22 can abut against the cylinder body 100 stably. The hoisting assembly 1 can connect multiple abutment 22 to connect multiple through structures 2 at the same time, which facilitates the hoisting of the cylinder body 100. The cylinder body 100 can be hoisted without the help of the cylinder liner hole and the gland hole, avoiding the situation where the wire rope passes through the cylinder liner hole and the gland hole, causing wear to the cylinder liner hole wall and the gland hole wall, thus ensuring the subsequent assembly accuracy. Meanwhile, the two abutting parts 22 corresponding to any through-body 21 abut against the cylinder body 100, meaning that the two abutting parts 22 corresponding to any through-body 21 are in a clamping state against the cylinder body 100. The multiple through-structures 2 are relatively stable relative to the cylinder body 100, ensuring the stability of the lifting tool during lifting, reducing the risk of impact loads, and guaranteeing the safety of lifting. Furthermore, different working states of the lifting tool are used to lift cylinder bodies 100 in different positions, enabling the cylinder body 100 to maintain its original position, further improving the stability during lifting.

[0032] For example, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, four through-hole structures 2 are provided. When the hoisting tool is in the first working state, two through-hole bodies 21 are respectively inserted through two pipe holes in the first pipe hole group 101, and the four corresponding abutment members 22 are all connected to the hoisting assembly 1. The centroids of the two through-hole bodies 21 are equidistant from the centroids of the cylinder body 100. When the hoisting tool is in the second working state, the four through-hole bodies 21 are respectively inserted through two pipe holes in the first pipe hole group 101 and two pipe holes in the second pipe hole group 102. The four abutment members 22 located on the same side of the cylinder body 100 away from the placement platform are all connected to the hoisting assembly 1, and the centroids of the four through-hole bodies 21 are equidistant from the centroids of the cylinder body 100. It is understandable that by setting four through structures 2, the distance between the centroid of the through body 21 and the centroid of the cylinder body 100 is equal in both the first and second working states. In other words, the distance between the corresponding four abutting parts 22 and the centroid of the cylinder body 100 is equal, thereby enabling the corresponding four abutting parts 22 to form four lifting points. The four lifting points are located at the four vertices of the same rectangle parallel to the placement platform. In other words, two of the lifting points are symmetrical with the other two lifting points about the center plane of the cylinder body 100. By using the four-point balance lifting principle, the cylinder body 100 is subjected to uniform force and has a stable posture during the lifting process, preventing the cylinder body 100 from overturning during the lifting process.

[0033] Of course, in other embodiments, the through-hole structure 2 can also be set to six, eight, or even more. For example, six through-hole structures 2 are provided along the length of the cylinder body 100. When the hoisting tool is in the first working state, three through-hole bodies 21 are respectively inserted into the three pipe holes of the first pipe hole group 101, and the six corresponding abutment members 22 are all connected to the hoisting assembly 1. Among the three through-hole bodies 21, the distance between the two through-hole bodies 21 located at both ends and the middle through-hole body 21 is equal, and the distance between the centroid of the two through-hole bodies 21 and the centroid of the cylinder body 100 is equal. When the hoisting tool is in the second working state, the six through-hole bodies 21 are respectively inserted into the three pipe holes of the first pipe hole group 101 and the second pipe hole group 101. The three pipe perforations of the perforation group 102 and the six abutment members 22 located on the same side of the cylinder body 100 away from the placement platform are all connected to the hoisting assembly 1. Among the three perforated bodies 21 in the first pipe perforation group 101, the distance between the two perforated bodies 21 at both ends and the middle perforated body 21 is equal, and the centroid of the two perforated bodies 21 is equal to the centroid of the cylinder body 100.

[0034] In this embodiment, the centroid of the penetrating body 21 refers to the geometric center of the penetrating body 21, and the centroid of the cylinder body 100 refers to the geometric center of the cylinder body 100.

[0035] For example, such as Figures 3-5 As shown, the hoisting assembly 1 includes a hook 11, a connecting rope 12, and multiple intermediate connectors 13. The connecting rope 12 is hung on the hook 11, and the abutment member 22 is detachably connected to the connecting rope 12 through the intermediate connectors 13. It can be understood that the detachable connection between the abutment member 22 and the connecting rope 12 through the intermediate connectors 13 facilitates the detachable connection between the hoisting assembly 1 and the through-structure 2.

[0036] Specifically, such as Figures 3-5 As shown, the hoisting assembly 1 includes multiple connecting ropes 12, each with its middle section attached to a hook 11. Both ends of each connecting rope 12 are detachably connected to intermediate connecting pieces 13. This means that each connecting rope 12 can simultaneously connect to two abutment pieces 22, and since the middle section of each connecting rope 12 is attached to the hook 11, at the beginning of hoisting, before the cylinder body 100 moves, the connecting rope 12 can move relative to the hook 11 to fine-tune its position, ensuring that the abutment pieces 22 connected to both ends of the connecting rope 12 can bear force normally, resulting in a more even force distribution on the entire hoisting tool.

[0037] In this embodiment, the hoisting assembly 1 includes two connecting ropes 12 and four intermediate connectors 13, with the middle of each of the two connecting ropes 12 being hung on a hook 11.

[0038] In some embodiments, such as Figures 3-4 As shown, the abutment member 22 includes a detachably connected sleeve 221 and a lifting lug 222. The side of the sleeve 221 away from the lifting lug 222 is detachably connected to the main body 21, and the side of the lifting lug 222 away from the sleeve 221 is detachably connected to the hoisting assembly 1. The sleeve 221 can abut against the cylinder body 100, and the lifting lug 222 is detachably connected to the connecting rope 12 via an intermediate connector 13. It can be understood that the detachably connected sleeve 221 and lifting lug 222 facilitate the detachable connection of the connecting rope 12 to the abutment member 22 and the main body 21.

[0039] Furthermore, the sleeve 221 includes a connected cylindrical body 2211 and an abutment piece 2212. The inner wall of the cylindrical body 2211 is provided with threads, and the ends of the lifting lug 222 and the through-body 21 are both threadedly connected to the cylindrical body 2211. In this embodiment, the through-body 21 is rod-shaped, and both ends of the through-body 21 are provided with threaded sections that engage with the threads of the cylindrical body 2211.

[0040] Specifically, the outer wall of the cylinder 2211 can abut against the wall of the pipe perforation, and the abutment piece 2212 can abut against the outer wall of the cylinder body 100.

[0041] In this embodiment, as Figures 8-9 As shown, the cylinder 2211 includes a first sub-cylinder 22111 and a second sub-cylinder 22112 connected to each other. The first sub-cylinder 22111 and the second sub-cylinder 22112 are axially coincident and have the same outer diameter. The inner diameter of the first sub-cylinder 22111 is smaller than the inner diameter of the second sub-cylinder 22112. The abutment piece 2212 is connected to the end of the second sub-cylinder 22112 away from the first sub-cylinder 22111. The first sub-cylinder 22111 is threadedly connected to the end of the main body 21, and the second sub-cylinder 22112 is threadedly connected to the lifting lug 222.

[0042] Furthermore, the lifting lug 222 is provided with a receiving groove, and the thread at the end of the through-body 21 is set at a certain distance from its own end face. When both the through-body 21 and the lifting lug 222 are threadedly connected to the cylinder 2211, part of the through-body 21 is located in the receiving groove.

[0043] In some embodiments, the intermediate connector 13 includes a threaded clip 131 and a connecting pin 132, the connecting pin 132 being able to pass through the clip 131 and the lifting lug 222 on the side away from the sleeve 221. It is understood that the connecting pin 132 being able to pass through the clip 131 and the lifting lug 222 on the side away from the sleeve 221 facilitates a detachable connection between the intermediate connector 13 and the lifting lug 222.

[0044] Furthermore, both ends of the connecting rope 12 are provided with connecting rings 121, and the detachable clip 131 can be inserted into the connecting rings 121, thereby facilitating the detachable connection between the lifting lug 222 and the connecting rope 12. The detachable clip 131 and the connecting pin 132 are both existing technologies, and their specific structures will not be described in detail in this embodiment.

[0045] Furthermore, such as Figures 8-9 As shown, the lifting lug 222 includes a first connecting portion 2221 and a second connecting portion 2222 connected together. A receiving groove is formed in the first connecting portion 2221, and a thread is formed on the outer side of the first connecting portion 2221, which is threadedly connected to the second sub-cylinder 22112. The second connecting portion 2222 is plate-shaped and has a connecting hole 2223, through which the connecting pin 132 can pass.

[0046] In this embodiment, as Figure 3 and Figure 5 As shown, the hook 11 includes a main body 111, a first connecting hook, a second connecting hook 112, and a third connecting hook 113. The first connecting hook is located at one end of the main body 111 and is used to connect to an external drive device. The second connecting hook 112 and the third connecting hook 113 are located at the other end of the main body 111. One connecting rope 12 is attached to the second connecting hook 112, and the other connecting rope 12 is attached to the third connecting hook 113. It is understood that the first connecting hook is used to connect to the external drive device, facilitating the external drive device to drive the hook 11 to move, thereby driving the aforementioned lifting tool to lift the cylinder body 100. The second connecting hook 112 and the third connecting hook 113 are located at the other end of the main body 111, and the two connecting ropes 12 are respectively attached to the second connecting hook 112 and the third connecting hook 113 to reduce interference between the two connecting ropes 12 and ensure the smooth movement of the connecting ropes 12 during the initial lifting operation, i.e., before lifting the cylinder body 100. An external drive unit can drive the vehicle.

[0047] In this embodiment, the connecting rope 12 can be a steel wire rope, and the hook 11, intermediate connecting piece 13 and threading structure 2 can all be made of high-strength titanium alloy material, which can lift the weight of the tool as a whole while ensuring strength, making it easy to use.

[0048] This embodiment also provides a hoisting device, including a crane and the above-mentioned hoisting tool. The crane and the hoisting component 1 are detachably connected. When hoisting the cylinder body 100, it can avoid damage to the cylinder liner bore and the grate bore, and improve the hoisting stability.

[0049] In this embodiment, the connecting lifting device structure of the crane is detachably connected to the hook 11 in the lifting assembly 1.
