Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a lifting device for a marine diesel engine cylinder. Background Art

[0002] Lifting devices are often used to transport large mold workpieces. To ensure safe transportation, heavy and bulky workpieces cannot be lifted using conventional lifting devices, but rather specialized lifting devices pre-produced for this purpose. Marine diesel engines typically consist of a cylinder block, engine base, and frame. These are relatively large and heavy, so specialized cylinder block lifting devices are required for lifting during transfer.

[0003] Patent No. CN113401780A discloses a lifting tool for a marine diesel engine cylinder production line, including a hanging plate and a positioning fixture rod. The inner end of the positioning fixture rod is provided with a positioning block whose shape matches the surface of the diesel engine cylinder block. The upper end of the positioning fixture rod is connected to a movable sleeve. The first lifting hook ring and the second lifting hook ring are both located at the upper end of the hanging plate. The positioning mechanism is located on the outside of the movable sleeve, the fixing mechanism is located on both sides of the second lifting hook ring, and the limit block is located below the second lifting hook ring. This patent provides a lifting tool for lifting the diesel engine cylinder block in the marine diesel engine cylinder block production line, which can fix the diesel engine cylinder block in multiple directions according to the uneven surface of the diesel engine cylinder block.

[0004] Since the positions of the cylinder ports of different types of marine diesel engines are different, the above-mentioned lifting device can only be used for a single type of diesel engine. When producing other types of diesel engines, the diesel engine cylinder block cannot be clamped well due to the different positions of the cylinder ports. This is especially true for newly developed diesel engine cylinder blocks. The production line does not have special lifting tooling, and a new set of lifting tooling needs to be developed for the newly developed diesel engine cylinder block. Utility Model Content

[0005] To address the above-mentioned issues, the present invention provides a marine diesel engine cylinder lifting device. By providing a fixing plate, a clamping cylinder, and a fixing column, the lifting device can be used even if the cylinder port of the marine diesel engine is positioned differently, thereby improving the applicability of the lifting device and eliminating the need for a dedicated lifting device.

[0006] A marine diesel engine cylinder lifting device comprises: a hanging plate, with two horizontally arranged guide grooves on the bottom side, and the two guide grooves are symmetrically arranged on both sides of the hanging plate; two bearings, fixed to the bottom side of the hanging plate, and the opposite sides are arranged on both sides of any guide groove, and a bidirectional screw rod is matched and connected to the two bearings, and one end of the bidirectional screw rod is transmission-connected to a driving motor; two first longitudinal beams, arranged on the bottom side of the hanging plate, and the top end is slidably connected to the guide groove and matched with the bidirectional screw rod; two second longitudinal beams, arranged on the bottom side of the hanging plate, symmetrically arranged with the two first longitudinal beams, and the top end is slidably connected to the other guide groove; two fixed plates, arranged vertically on the bottom side of the hanging plate, and the two fixed plates are arranged in parallel, and the two ends of any fixed plate are respectively connected to the first longitudinal beam and the second longitudinal beam, and a slide groove is opened on any fixed plate; a plurality of cartridges pass through the slide groove and are slidably connected to the slide groove, and a fixing column is arranged in the cartridge.

[0007] In a preferred embodiment, the marine diesel engine cylinder lifting device further comprises: a clamping block slidably connected to the first longitudinal beam and the second longitudinal beam via a first sliding sleeve.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other in any way.

[0023] The following describes the marine diesel engine cylinder lifting device in detail with reference to the accompanying drawings and embodiments. Example

[0024] A marine diesel engine cylinder lifting device comprises: a hanging plate 10, with two horizontally arranged guide grooves 11 on the bottom side, and the two guide grooves 11 are symmetrically arranged on both sides of the hanging plate 10; two bearings 20, fixed to the bottom side of the hanging plate 10, and the opposite sides are arranged on both sides of any guide groove 11, and a bidirectional screw rod 21 is matched and connected to the two bearings 20, and one end of the bidirectional screw rod 21 is transmission-connected to a drive motor 22; two first longitudinal beams 30 are arranged on the bottom side of the hanging plate 10, and the top end is slidably connected to the guide groove 11 and is connected to the bidirectional screw rod 21. Matching connection; two second longitudinal beams 31 are arranged on the bottom side of the hanger 10, symmetrically arranged with the two first longitudinal beams 30, and the top end is slidingly connected to another guide groove 11; two fixed plates 40 are vertically arranged on the bottom side of the hanger 10, and the two fixed plates 40 are arranged in parallel. The two ends of any fixed plate 40 are respectively connected to the first longitudinal beam 30 and the second longitudinal beam 31, and a slide groove 41 is opened on any fixed plate 40; a plurality of clamps 42 pass through the slide groove 41 and are slidingly connected to the slide groove 41, and a fixing column 43 is provided in the clamp 42.

[0025] During operation, the fixing column 43 is assembled with the cartridge 42 and fixed with bolts. The position of the cartridge 42 is then adjusted so that the fixing column 43 corresponds to the cylinder block of the marine diesel engine. The drive motor 22 is started to rotate the bidirectional screw rod 21, thereby driving the two first longitudinal beams 30 and the second longitudinal beam 31 to move together until the fixing column 43 penetrates the circular hole groove of the marine diesel engine cylinder block and the marine diesel engine cylinder block fits with the fixing plate 40. This ensures that the lifting device can still be used even if the position of the cylinder port of the marine diesel engine is different, thereby improving the applicability of the lifting device and eliminating the need to develop a special lifting device.

[0026] A rubber layer may be provided on the inner side of the fixing plate 40 to protect the cylinder block of the marine diesel engine.

[0027] The thread directions of the bidirectional screw rod 21 are different, and the two first longitudinal beams 30 can move toward or away from each other under the action of the driving motor 22 .

[0028] The first longitudinal beams 30 are fixed with nuts and then assembled on the bidirectional screw rod 21 .

[0029] The outer end diameter of the fixing column 43 is optional, thereby ensuring the port of cylinders with different apertures. Example

[0030] Example 2 is an improvement on Example 1, in order to further fix the cylinder block of a marine diesel engine.

[0031] The marine diesel engine cylinder lifting device further comprises a clamping block 32 slidably connected to the first longitudinal beam 30 and the second longitudinal beam 31 via a first sliding sleeve 33 .

[0032] During operation, the first sliding sleeve 33 is moved so that the first sliding sleeve 33 just contacts the top edge protrusion of the marine diesel engine cylinder block, and then the first sliding sleeve 33 is fixed by bolts.

[0033] If there is no protrusion on the top edge of the marine diesel engine cylinder body, the position of the clamping block 32 can be adjusted to the top side of the marine diesel engine cylinder body to avoid interference with the marine diesel engine cylinder body. Example

[0034] Example 3 is an improvement on Example 1 or 2, in order to solve the problem of cylinder hoisting.

[0036] During operation, the two ends of the strip rubber pad 54 are fixedly connected to the telescopic springs 52 on the first longitudinal beam 30 and the second longitudinal beam 31 respectively, and then the second hook 53 of the telescopic spring 52 is hooked on the first hook 51, and the position of the second sliding sleeve 50 is adjusted so that the strip rubber pad 54 is just tightly fitted to the marine diesel engine cylinder block, thereby ensuring that the bottom side of the marine diesel engine cylinder block is supported by the strip rubber pad 54, avoiding the diesel engine cylinder block from being unstable due to loose installation of the fixing column 43 or other mechanical problems, thereby improving the reliability of lifting.

[0037] In the embodiment 2 or 3, the first sliding sleeve 33 and the second sliding sleeve 50 can be fixedly connected by bolts through the mounting holes 34 on the first longitudinal beam 30 and the second longitudinal beam 31 .

[0038] In order to facilitate transportation, the marine diesel engine cylinder lifting device may further include a lifting ring 12 , which is fixed to the top side of the lifting plate 10 .

[0039] The present application also discloses a marine diesel engine production line, including the marine diesel engine cylinder lifting device.

[0040] When working, a suitable fixing column 43 will be selected, the fixing column 43 will be assembled with the cartridge 42 and fixed with bolts, and then the position of the cartridge 42 will be adjusted so that the fixing column 43 corresponds to the marine diesel engine cylinder body, and the driving motor 22 will be started to drive the bidirectional screw rod 21 to rotate, thereby driving the two first longitudinal beams 30 to move, and driving the second longitudinal beam 31 to move together, until the fixing column 43 penetrates the circular hole groove of the marine diesel engine cylinder body, and the marine diesel engine cylinder body fits with the fixing plate 40; then, the first sliding sleeve 33 is moved so that the first sliding sleeve 33 just supports the convex edge of the top side of the marine diesel engine cylinder body. The first sliding sleeve 33 is then fixed with bolts; finally, the two ends of the strip rubber pad 54 are fixedly connected to the telescopic springs 52 on the first longitudinal beam 30 and the second longitudinal beam 31 respectively, and then the second hook 53 of the telescopic spring 52 is hooked on the first hook 51, and the position of the second sliding sleeve 50 is adjusted so that the strip rubber pad 54 is just tightly fitted to the marine diesel engine cylinder block, thereby ensuring that the bottom side of the marine diesel engine cylinder block is supported by the strip rubber pad 54, avoiding instability of the diesel engine cylinder block due to loose installation of the fixing column 43 or other mechanical problems, thereby improving the reliability of the lifting.
