Description

Technical Field

[0001] The utility model relates to the field of ocean engineering equipment, and more specifically, to a high-speed anchor throwing device for a deep-sea cable winch. Background Technique

[0002] As a special cable towing device, the cable winch is used for taking in and paying out cables, towing ships and offshore equipment without self-propulsion capabilities (such as barges, crane ships, floating docks, dredgers, and drilling platforms, etc.) and ships that have lost their self-propulsion capabilities, and is a key device on certain military auxiliary ships and civilian ships.

[0003] Currently, the deep-sea cable winches used in China are all imported equipment, and the imported cable winches basically adopt a hydraulic low-pressure drive system. The low-pressure motors of such drive systems are monopoly products of a few enterprises, so the procurement cost is relatively expensive. Alternative products can adopt a hydraulic medium-high pressure system or an electric drive system.

[0004] However, when the deep-sea cable winch throws the anchor at high speed, a large negative power will be generated. At this time, the maximum dynamic braking force is 500 - 600 tons, and the maximum anchor throwing speed exceeds 60 m / min. At this time, the load power is significantly oversized, about 3 - 5 times the power of the prime mover. Therefore, it is necessary to study how to solve the problem of absorbing the large negative power generated by high-speed anchor throwing. Content of the Utility Model

[0005] Aiming at the defects existing in the prior art, the purpose of the utility model is to provide a high-speed anchor throwing device for a deep-sea cable winch, which solves the problem of large negative power generated by high-speed anchor throwing of the deep-sea cable winch in a hydraulic medium-high pressure system or an electric drive system by automatically switching the closed and open states of the water-cooled brake and the friction clutch, and can realize a free and controllable high-speed anchor releasing working condition.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A high-speed anchor throwing device for a deep-sea cable winch includes a prime mover, a speed reducer, and a cable winch drum that are sequentially meshed and connected;

[0008] The speed reducer is provided with a water-cooled brake and a friction clutch;

[0009] The core shaft of the water-cooled brake is connected to the gear shaft of the speed reducer;

[0010] The housing of the water-cooled brake is connected to the housing of the speed reducer;

[0011] The core shaft of the friction clutch is connected to the gear shaft of the speed reducer;

[0012] The housing of the friction clutch is connected to the gear of the speed reducer.

[0013] Preferably, the water-cooled brake is a hydraulic water-cooled brake or a pneumatic water-cooled brake.

[0014] Preferably, a hydraulic or pneumatic control pipeline is connected to the water-cooled brake.

[0015] Preferably, the friction clutch is a hydraulic friction clutch or a pneumatic friction clutch.

[0016] Preferably, a hydraulic or pneumatic control pipeline is connected to the friction clutch.

[0017] Preferably, the water-cooled brake is located behind the friction clutch.

[0018] A high-speed anchor throwing device for a deep-sea cable winch provided by the present utility model is convenient to arrange and implement, has a low manufacturing cost, and good practicability. At the same time, it also breaks the current monopoly phenomenon and provides a solution for the domestic substitution of deep-sea cable winches. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 is a schematic structural diagram of the high-speed anchor throwing device for a deep-sea cable winch of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to better understand the above technical solutions of the present utility model, the technical solutions of the present utility model will be further described below with reference to the drawings and embodiments.

[0021] Combined Figure 1 As shown, a high-speed anchor throwing device for a deep-sea cable winch provided by the present utility model includes a prime mover 5, a speed reducer 3, and a cable winch drum 1 that are sequentially meshed and connected.

[0022] A water-cooled brake 4 and a friction clutch 2 are arranged on the intermediate shaft of the speed reducer 3.

[0023] The core shaft of the water-cooled brake 4 is connected to the gear shaft 9 of the speed reducer 3, and the housing of the water-cooled brake 4 is connected to the housing of the speed reducer 3.

[0024] The core shaft of the friction clutch 2 is connected to the gear shaft 9 of the speed reducer 3, and the housing of the friction clutch 2 is connected to the gear 8 of the speed reducer 3.

[0025] According to the rated torque and reduction ratio of the cable winch drum 1, the rated transmission torque of the water-cooled brake 4 is calculated. At the same time, according to the rated heat dissipation power and rated speed of the water-cooled brake 4, a suitable model of the water-cooled brake 4 is selected and determined. The control of the water-cooled brake 4 has two types: hydraulic and pneumatic, and one can be selected according to needs. A hydraulic or pneumatic control pipeline 7 is arranged on the water-cooled brake 4, and it is opened or closed through pneumatic or hydraulic control.

[0026] Similarly, select the appropriate model of the friction clutch 2 according to the rated torque and rated speed of the winch drum 1 of the towing cable machine. The control of the friction clutch 2 also has two types: hydraulic and pneumatic. One can be selected according to needs. Hydraulic or pneumatic control pipelines 10 are arranged on the friction clutch 2, and opening or closing is achieved through pneumatic or hydraulic control.

[0027] The water-cooled brake 4 is arranged behind the friction clutch 2, that is, in the transmission chain, the friction clutch 2 is closer to the prime mover 5, so that when the friction clutch 2 is disengaged, the prime mover 5 can be disengaged to achieve the protection purpose, and the water-cooled brake 4 can control the anchor release of the winch drum 1 of the towing cable machine.

[0028] The working condition control of the high-speed anchor throwing device for the deep-sea towing cable machine of the present utility model is as follows:

[0029] During the anchor lifting working condition, the water-cooled brake 4 is opened, and at the same time, the friction clutch 2 is closed. The power of the prime mover 5 is transmitted to the open gear 6 of the winch drum 1 of the towing cable machine through the speed reducer 3 to complete the anchor lifting working condition.

[0030] During the high-speed anchor throwing working condition, the water-cooled brake 4 is closed, and the friction clutch 2 is opened, thus disconnecting the connection between the prime mover 5 and the winch drum 1 of the towing cable machine, protecting the prime mover 5, and the anchor release is completely freely controlled by the water-cooled brake 4.

[0031] In the high-speed anchor throwing device for the deep-sea towing cable machine of the present utility model, both the water-cooled brake 4 and the friction clutch 2 adopt automatic control type (pneumatic or hydraulic) equipment, which ensures that the anchor lifting and anchor release working conditions can be switched arbitrarily according to the usage situation, and is safe and reliable. There are also common and mature products for both the water-cooled brake 4 and the friction clutch 2, and the selection and procurement are convenient. During actual design and selection, as long as the load power and torque are calculated according to the dynamic braking force of the anchor release and the anchor release rope speed, and appropriate water-cooled brake 4 and friction clutch 2 are selected and matched, the problem of high-speed anchor release of the deep-sea towing cable machine can be solved well. This mechanism arrangement also has strong adaptability to the parameter changes of the anchor release. The selection of the water-cooled brake 4 is easy, and the installation and maintenance are also convenient.

[0032] Those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. As long as within the scope of the substantial spirit of the present utility model, the changes and modifications of the above embodiments will fall within the scope of the claims of the present utility model.
