Description

Hoisting tool for marine diesel engine vibration compensator

Technical Field

The utility model relates to a jack-up is with equipping, concretely relates to marine diesel engine vibration compensator's lifting device belongs to the diesel engine and makes technical field.

Background

During the operation of the marine diesel engine, under the combined action of the pressure in the cylinder and the mass inertia force of the reciprocating motion of the piston, the vertical force on the piston is transmitted to the crank through the crank-connecting rod mechanism, and at the moment, the rack guide rail bears the side thrust, so that the guide rail moment is generated, the guide rail moment is the main excitation source of the vibration of the main engine, and the guide rail moment is particularly obvious on the main engine with 7 cylinders and below, so that the vibration compensator is very necessary for the diesel engines with 7 cylinders and below. Under the normal condition, the vibration compensator is installed below a scavenging manifold of a diesel engine, and the vibration compensator cannot be normally lifted by a travelling crane due to the obstruction of an exhaust manifold in the workshop installation or later maintenance process, so that the problem is necessary to be effectively solved.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the difficulty that current vibration compensator lifted by crane, provide a marine diesel engine vibration compensator's lifting device, avoid the position hindrance of exhaust collector, realize the driving and directly lift by crane vibration compensator, reach easy operation and improve the effect of operating efficiency.

The utility model provides a technical scheme that its technical problem adopted as follows:

the utility model provides a marine diesel vibration compensator's lifting device, this vibration compensator install in the below of marine diesel's exhaust collector, a serial communication port, lifting device is C style of calligraphy structure, and its notch is used for walking around exhaust collector, this lifting device is including last hanger plate, lower hanger plate and support frame, the support frame is vertical to be arranged, go up the hanger plate transversely with an end fixed connection in the upper end of support frame just is equipped with the lifting eye that is used for connecting the driving lifting hook, the hanger plate transversely with an end fixed connection in the lower extreme of support frame just is equipped with the lifting eye that is used for connecting the vibration compensator lifting hook down.

As a further improvement, the upper hanging plate is provided with a transfer hole for hoisting the hoisting tool.

As a further improvement, the transfer hole is positioned on the gravity center line of the hoisting tool.

As a further improvement, reinforcing rib plates are respectively and fixedly connected between the upper hanging plate and the support frame and between the lower hanging plate and the support frame.

As a further improvement, the distance from the lifting hole of the upper lifting plate to the support frame is equal to the distance from the lifting hole of the lower lifting plate to the support frame.

The utility model has the advantages of as follows:

1. the hoisting tool is of a C-shaped structure, and the notch of the hoisting tool can accommodate the body of the exhaust collecting pipe, so that the travelling crane can overcome the interference of the exhaust collecting pipe, and the vibration compensator can be directly hoisted.

2. The utility model discloses have the reinforcing structure, avoided the collision with the exhaust collector.

3. The utility model discloses simple structure has improved on-the-spot operating efficiency.

In a word, the utility model provides high operating efficiency has guaranteed the safety of exhaust collector, has realized that vibration compensator's direct lifts by crane, can be applicable to the hoist and mount operation of vibration compensator when maintenance on workshop installation or the ship.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1 is an upper hanging plate, 2 is a lower hanging plate, 3 is a transfer hole, 4 is a support frame, 5 is a reinforcing rib plate, and 6 is a lifting hole.

Detailed Description

The following detailed description of the present invention is provided in connection with the accompanying drawings and examples, but should not be construed to limit the scope of the invention.

The utility model is used for marine diesel engine vibration compensator's direct hoist and mount, the lifting hook of driving is connected to this lifting device one end, and the lifting hook that links to each other with vibration compensator is connected to the other end, this vibration compensator install in the below of marine diesel engine's exhaust collector.

Referring to fig. 1, the lifting tool is a C-shaped structural member with a notch for bypassing the exhaust manifold. The hoisting tool comprises an upper hoisting plate 1, a lower hoisting plate 2 and a support frame 4.

The supporting frame 4 is vertically arranged, the upper hanging plate 1 is transversely arranged, one end part of the upper hanging plate is fixedly connected to the upper end of the supporting frame 4, and a lifting hole 6 used for connecting a crane lifting hook is formed in the upper hanging plate 1. The lower hanging plate 2 is transversely arranged, one end of the lower hanging plate is fixedly connected to the lower end of the support frame 4, and a lifting hole 6 for connecting a vibration compensator lifting hook is formed in the lower hanging plate 2. Two lifting holes 6 of the upper lifting plate 1 and the lower lifting plate 2 are arranged at one end far away from the corner of the C-shaped structure, and the horizontal distances from the lifting holes to the support frame 4 are equal.

Referring to fig. 1, a transfer hole 3 is formed in the upper hanging plate 1, and the transfer hole 3 is located on a gravity center line of the hoisting tool; the transfer hole 3 is only used for hoisting and transferring the hoisting tool, and is not used for hoisting the vibration compensator, so that the hoisting tool is ensured to be stable in the transfer process.

Because lifting device size is great, in addition vibration compensator self weight, if do not strengthen the design, lifting device very easily produces the deformation among the hoist and mount process, and then collides with the exhaust collector, leads to the exhaust collector to damage, consequently at lifting device two corners, between upper hanger plate 1 and the support frame 4 and between lower hanger plate 2 and the support frame 4 respectively fixedly connected with deep floor 5. The reinforcing rib plate 5 is arranged through stress calculation, and the problem of stress concentration in the hoisting process can be effectively solved.

The utility model discloses a concrete application as follows:

connecting a transfer hole 3 of the hoisting tool with a crane hook, and transferring the tool to a hoisting position of a vibration compensator by controlling a crane; and then, the lifting hole 6 of the upper lifting plate 1 is connected with a crane lifting hook, the lifting hole 6 of the lower lifting plate 2 is connected with the lifting hook connected with the vibration compensator, and the vibration compensator is directly lifted by controlling the crane.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. All equivalent changes and modifications made according to the content of the present invention shall be the technical scope of the present invention.
