Description

Technical Field

[0001] The utility model relates to the technical field of ship maintenance, in particular to a supporting device for ship maintenance. Background Art

[0002] In the current shipbuilding industry, ship maintenance is also a top priority for the entire shipbuilding industry. Currently, maintenance platforms are basically set up in land factories or ports;

[0003] When repairing a large ship, first the support base needs to be driven down to below the water surface by a hydraulic lifting mechanism, and then the large ship is guided by a tugboat through a tug rope, and then two or more small boats are used on both sides of the large ship to make fine adjustments to the large ship so that the large ship can smoothly enter the support base between the two maintenance platforms, and then the large ship is lifted out of the water by a hydraulic lifting mechanism for easy repair;

[0004] When guiding a large ship, it is necessary to use multiple small boats to adjust the direction, which tests the skills of the small boat drivers and is somewhat dangerous. In addition, when making fine adjustments, the small boats need to lightly touch the large ship several times for adjustment, which is a more troublesome operation. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing large-scale ship maintenance equipment has no guiding structure and often requires small boats for guidance, which leads to certain dangers for the drivers of small boats and the overall guiding operation is relatively complicated.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is a support device for ship maintenance, including two maintenance platforms, a supporting frame is fixed at the bottom between the two maintenance platforms, a maintenance crane is fixed on the upper side of the maintenance platform, a watertight hydraulic cylinder is fixed at the bottom of the maintenance platform, and curved slide grooves are symmetrically opened along the supporting frame on the opposite sides of the two maintenance platforms, and a guide mechanism is slidingly provided in the curved slide groove.

[0007] As a further solution of the utility model: the guide mechanism includes a sliding curved plate, which can be driven to move by the friction force of the transmission wheel, a connecting curved plate is fixed in the middle of one side of the sliding curved plate, a curved guide plate is fixed on one side of the connecting curved plate, a curved groove is opened on one side of the curved guide plate, and a number of guide rollers are rotatably provided between the upper and lower sides of the curved groove, which are used to guide the ship into between the two maintenance platforms.

[0008] As a further solution of the utility model: a plurality of transmission motors are arranged above and below the curved slide groove inside the maintenance platform, and a transmission wheel is fixed on the output end of the transmission motor in the curved slide groove, which can drive the sliding curved plate to move by friction.

[0009] As a further solution of the utility model: a plurality of the transmission wheels are located on both sides of the sliding curved plate, and the outer sides of the transmission wheels are in contact with the outer sides of the sliding curved plate.

[0010] As a further solution of the utility model: the curvature of the curved slide groove, the sliding curved plate, the connecting curved plate and the curved guide plate are the same, so that the guide mechanism can slide better.

[0011] As a further solution of the utility model: the length of the guide mechanism is equal to the length of the curved slide groove.

[0012] As a further solution of the utility model: the lower side of the sliding curved plate is provided with an arc chamfer, so as to reduce the contact area between the lower side of the sliding curved plate and the lower side of the curved slide groove, thereby reducing the friction resistance.

[0013] Compared with the prior art, the utility model has the following advantages: the utility model adds two guide structures, which can be extended by the transmission wheel to guide the guide mechanism so as to guide the ship. It is no longer necessary to use multiple small boats to turn and guide the large ship, so that the ship can enter the support frame between the two maintenance platforms for maintenance.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a technical solution to solve the existing problems raised in the background technology.

[0024] Combined with Figure 1-5 It can be known that the structure includes two maintenance platforms 1, a supporting frame 2 is fixed at the bottom between the two maintenance platforms 1, a maintenance crane is fixed on the upper side of the maintenance platform 1, a watertight hydraulic cylinder 3 is fixed at the bottom of the maintenance platform 1, and curved slide grooves 1.1 are symmetrically opened along the supporting frame 2 on the opposite side of the two maintenance platforms 1 to limit the movement of the guide mechanism 4, and a guide mechanism 4 is slidably provided in the curved slide groove 1.1 to guide large ships to enter above the supporting frame 2.

[0025] The guide mechanism 4 includes a sliding curved plate 4.1, which can be driven to move by the friction of the transmission wheel 6. A connecting curved plate 4.2 is fixed in the middle of one side of the sliding curved plate 4.1, a curved guide plate 4.3 is fixed on one side of the connecting curved plate 4.2, a curved groove 4.4 is opened on one side of the curved guide plate 4.3, and a plurality of guide rollers 4.5 are rotatably arranged between the upper and lower sides of the curved groove 4.4 to guide the ship to enter between the two maintenance platforms 1; a plurality of transmission motors 5 are arranged above and below the curved slide groove 1.1 inside the maintenance platform 1, and a plurality of transmission motors 5 are fixed at the output end of the transmission motor 5 at the curved slide groove 1.1. The transmission wheel 6 can drive the sliding curved plate 4.1 to move through friction; a plurality of the transmission wheels 6 are located on both sides of the sliding curved plate 4.1, and the outer side of the transmission wheel 6 is in contact with the outer side of the sliding curved plate 4.1; the curvature of the curved slide 1.1, the sliding curved plate 4.1, the connecting curved plate 4.2 and the curved guide plate 4.3 are the same, so that the guide mechanism 4 can slide better; the length of the guide mechanism 4 is equal to the length of the curved slide 1.1; the lower side of the sliding curved plate 4.1 is provided with an arc chamfer to reduce the contact area between the lower side of the sliding curved plate 4.1 and the lower side of the curved slide 1.1, thereby reducing friction resistance.

[0026] The working principle of the present application is as follows: when repairing a large ship, firstly, the supporting frame 2 is lowered underwater by the watertight hydraulic cylinder 3, and then a plurality of transmission motors 5 are started to drive the transmission wheel 6 to rotate, so as to extend the guide mechanism 4 out of the curved slide groove 1.1. Since the guide mechanism 4 is an arc structure, the state of the two guide mechanisms 4 after being extended is similar to the shape of an "eight", so that the large ship can slowly move from the end with a wider opening to the end with a narrower opening, until it can be located above the supporting frame 2 under the guidance of the guide mechanism 4, and then the transmission motor 5 is started to drive the transmission wheel 6 to rotate, and the guide mechanism 4 is retracted into the curved slide groove 1.1 to complete the guiding, and then the large ship is pushed out of the water by the watertight hydraulic cylinder 3 for subsequent repairs.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
