Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, specifically to a winch device for a surveying ship. Background Technology

[0002] The winch on the survey vessel uses a winding hinge to retrieve and deploy various detection instruments, samplers, or underwater robots for deep-sea surveying, exploration, or scientific research.

[0003] In actual exploration at different depths, various detectors need to be deployed using hinges of appropriate lengths. However, in traditional winch devices, the distance between the winch and the base or ship's clamp is fixed. Therefore, when winding a long hinge, the limited distance between the winch and the base prevents the hinge from being fully wound onto the winch, affecting practical applications. To address this issue, we propose a winch device for a surveying vessel. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The winch device of this survey vessel uses a connecting assembly to allow the winch to be connected to the base in a relatively flexible manner. The screw and slider in the connecting assembly realize screw drive, and the slider is rotatably connected to the connecting shaft on the winch. In this way, the screw can drive the winch to slide up and down on the base, adjust the height between the base and the winch, meet the winding needs of hinges of different lengths, expand the applicability of the overall device, and improve the practicality of the overall device.

[0015] 2. The winch device of this survey vessel connects the connecting shaft of the winch to the output shaft of the drive motor through a transmission component.

At the same time, this design allows the user to simply adjust the position of the winch to ensure the stability of the center of gravity of the entire device and improve the overall stability of the device. It is suitable for applications where the actual survey vessel is in a turbulent sea environment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 A winch device for a surveying vessel includes: a base 1, a winch 2 for winding or releasing the hinge of a surveying instrument, and a drive motor 3 for providing the power required for the rotation of the winch 2. The drive motor 3 is fixedly mounted on the top surface of the base 1. A connecting shaft 21 is fixedly mounted inside the winch 2. The drive motor 3 is provided with a motor output shaft 31. The base 1 is also provided with a connecting assembly 4 and a transmission assembly 5. The connecting assembly 4 includes a slider 41 rotatably connected to the connecting shaft 21 and passing through one end of the winch 2, and a slider 41 rotatably connected to the connecting shaft 21. 21 passes through the T-shaped block 43 at the other end of the winch 2, the screw 42 is rotatably mounted on the base 1, and the extension seat 44 is fixedly mounted on the side of the T-shaped block 43; the slider 41 is threadedly connected to the screw 42, and the slider 41 is slidably connected to the base 1. The T-shaped block 43 is also slidably connected to the base 1. The extension seat 44 is located in the internal cavity of the base 1. A knob is provided on the end of the screw 42 that passes through the base 1, and the knob is provided with anti-slip texture. This design can prevent the phenomenon of hand slippage, thus facilitating practical application.

[0024] The transmission assembly 5 includes a square rod 51 located in the inner cavity of the base 1, a first disc-shaped shaft 52 fixedly installed at the end of the square rod 51 for rotatable connection between the square rod 51 and the base 1, a first secondary bevel gear 54 fixedly installed on the square rod 51, a first primary bevel gear 53 meshing with the first secondary bevel gear 54, a first gear shaft 531 for fixed connection between the first primary bevel gear 53 and the motor output shaft 31, a second disc-shaped shaft 55 rotatably disposed inside the extension seat 44, a second primary bevel gear 56 disposed in the inner cavity of the T-shaped block 43, a second gear shaft 561 for rotatable connection between the second primary bevel gear 56 and the T-shaped block 43, a second secondary bevel gear 57 meshing with the second primary bevel gear 56, and a fixed connection between the second secondary bevel gear 57 and the connecting shaft 21. The base 1 has a sliding groove for sliding the T-shaped block 43, and the length of the square rod 51 is the same as the length of the sliding groove. This design can ensure the transmission effect of the square rod 51, so that the winch 2 can still rotate after the drive motor 3 is started, even at different heights, thus meeting the actual winding hinge requirements. The extension seat 44 has a through hole for passing through the square rod 51. The second disc shaft 55 is also slidably connected to the square rod 51. There are two first disc shafts 52, and both first disc shafts 52 are rotatably connected to the base 1. The first gear shaft 531 is also rotatably connected to the base 1. The first secondary bevel gear 54 and the first main bevel gear 53 are both located in the internal cavity of the base 1.

[0025] Working principle: When adjusting the height of the winch 2 for hinges of different lengths, the two ends of the connecting shaft 21 on the winch 2 rotate the slider 41 and the T-block 43 respectively. Both the slider 41 and the T-block 43 are slidably mounted on the base 1. The screw 42, which is rotatably mounted on the base 1, is threadedly connected to the slider 41. Therefore, rotating the screw 42 drives the slider 41 to slide on the base 1, thereby causing the winch 2 to slide and achieving the purpose of adjusting the height of the winch 2. When the drive motor 3 on the base 1 is actually started, the motor output shaft... 31 is fixedly connected to the first main bevel gear 53 via the first gear shaft 531. The first main bevel gear 53 is also meshed with the first secondary bevel gear 54 fixed on the square rod 51. The square rod 51 is rotatably connected to the inner cavity of the base 1 via the first disc-shaped shafts 52 at both ends. The second disc-shaped shaft 55 is rotatably mounted inside the extension seat 44 fixed on the T-shaped block 43. The second disc-shaped shaft 55 is slidably connected to the square rod 51. The second disc-shaped shaft 55 is also connected to the second... The gear shaft 561 is connected for transmission. A second main bevel gear 56, which meshes with and is connected to the second secondary bevel gear 57, is fixed to the end of the second gear shaft 561. The second secondary bevel gear 57 is also fixedly connected to the third gear shaft 571 and the connecting shaft 21. Therefore, when the drive motor 3 is started and the motor output shaft 31 rotates, the following components are connected: the first gear shaft 531, the first main bevel gear 53, the first secondary bevel gear 54, the square rod 51, the second disc-shaped shaft 55, the pulley set 58, the second gear shaft 561, and the second main bevel gear 56. 6. Under the transmission action of the second bevel gear 57 and the third gear shaft 571, the connecting shaft 21 drives the winch 2 to rotate and perform the hinge winding operation. Since the extension seat 44 is located in the cavity inside the base 1 and has a through hole for the square rod 51 to pass through, the above structure still has the transmission effect when the winch 2, the connecting shaft 21, the T-shaped block 43 and the extension seat 44 slide and the winch 2 is at different heights, so as to ensure that the drive motor 3 can provide power to drive the winch 2 to rotate and wind the hinge.
