Description

Technical Field

[0001] The utility model relates to the technical field of winch driving, in particular to a multi-winch single-drive integrated mechanism and a ship. Background Art

[0002] The crane of the fully revolving crane ship can rotate within 360 degrees, which allows it to operate in any direction, greatly improving work efficiency and flexibility. Unlike traditional fixed cranes, the crane of the fully revolving crane ship can move freely on the hull and can perform lifting operations in different positions, greatly improving work efficiency.

[0003] The fully revolving pile-driving ship, which is similar to the fully revolving crane ship, is equipped with a pile driving frame and a pile driving system based on the crane. It can perform fully revolving pile driving operations, further expanding the functions of the fully revolving crane and thus playing a greater role in the field of piling construction.

[0004] Whether it is a fully revolving crane ship or a fully revolving pile driver, the basic components of its revolving device include: a cylinder fixed on the hull, a revolving unit, a boom, a revolving mechanism and a series of winches (main hook lifting, auxiliary hook lifting, boom luffing, cargo stabilization, rigging, etc.). The above winches are usually driven by motors or hydraulics and are centrally arranged on the revolving unit. In actual production activities, the existing integration methods of winches have the following limitations:

[0005] 1) The winch is driven by an electric motor, so each winch needs to be equipped with a drive motor and supporting electrical equipment, which leads to tight space inside the slewing unit.

[0006] 2) If the winch is hydraulically driven, each winch needs to be equipped with a hydraulic motor and a matching hydraulic pump station. The hydraulic pump station also needs to be driven by an electric motor / diesel engine, which leads to tight space inside the slewing unit.

[0007] 3) If power supply and cooling water supply are required between the hull and the slewing unit, a cable slip ring and a special cooling water connection mechanism are also required.

[0008] Therefore, how to simplify the winch integration method, reduce the space occupied by the winch integration mechanism, and reduce the production cost has become a technical problem that needs to be urgently solved by those skilled in the art. Utility Model Content

[0013] Preferably, the reduction box is a gear box.

[0014] Preferably, the number of the power output shafts is seven.

[0036] There are multiple power output shafts 132, and the multiple power output shafts 132 are arranged in parallel on one side of the torque transmission box 130. One end of the power output shaft 132 is connected to the torque transmission box 130, and the other end of the power output shaft 132 is connected to the through-axis 160 through the hydraulic torque converter 140; at least one winch 150 is installed on the through-axis 160.

[0037] The present application adopts a one-to-many approach, with a torque transmission box 130 provided on one side of the staggered winch 150. The power input shaft 131 of the torque transmission box 130 is transmission-connected to the diesel engine 110 via the reduction box 120, and is used to transmit the torque and speed of the diesel engine 110 to the torque transmission box 130; the power output shaft 132 of the torque transmission box 130 is transmission-connected to the winch 150 via the hydraulic torque converter 140, and is used to drive each winch 150 to move, which not only simplifies the structure of the winch integrated mechanism, reduces the volume of the winch integrated mechanism, but also reduces the production cost of the winch integrated mechanism.

[0038] In a specific embodiment, if Figure 1 As shown, there are multiple through-shafts 160, and the multiple through-shafts 160 are arranged at intervals in the transverse direction. One or two winches 150 are installed on each through-shaft 160, and the winches 160 on two adjacent through-shafts 160 are staggered in the axial direction to reduce the volume of the winch integration mechanism.

[0039] In a specific embodiment, if Figure 1 and Figure 2As shown, the torque transmission box 130 is arranged at one longitudinal end of the winch 150 along the transverse direction, and a plurality of transmission gears 133 are linearly meshed and arranged along the transverse direction in the box body of the torque transmission box 130, and all the transmission gears 133 have the same radial dimensions and are meshed and transmitted sequentially; one end of the power input shaft 131 extends axially through the box body, and one end of the power input shaft 131 is coaxially fixedly connected to one of the transmission gears 133.

[0041] It should be noted that: Figure 2 The direction of the arrow indicates the direction of rotation of the shaft or gear.

[0042] In a specific embodiment, if Figure 1 As shown, the reduction box 120 is a gear box; the number of the power output shafts 132 is seven.

[0045] The working process of the multi-winch single-drive integrated mechanism of the present application is as follows:

[0046] Based on the problem of a large number of winches in a slewing unit and difficulty in their arrangement, the present application proposes a multi-winch single-drive integrated mechanism, that is, power is provided by a set of diesel engines, torque is transmitted through a gear box, and a one-input and multiple-output power distribution method is realized in conjunction with a torque transmission box. The winches are respectively connected to each other through a hydraulic torque converter, and each winch can select engagement, pitch change, and disengagement according to usage needs, thereby simplifying the structure of the winch integrated mechanism and reducing the volume of the winch integrated mechanism.

[0047] The diesel engine is connected to the reduction box through a shaft, and the reduction box can reduce the speed of the winch according to actual needs; the reduction box is connected to the torque transmission box through the power input shaft, and with the torque transmission inside the torque transmission box, it can output multiple power output shafts according to user needs. The power output shaft is connected to the through-shaft of the winch through the hydraulic torque converter to form a complete one-to-multiple torque transmission chain.

[0048] Compared with the prior art, this application has at least the following beneficial technical effects:

[0049] 1) The centralized power source is adopted, which reduces the configuration of the independent drive unit of a single winch and simplifies the structure of the winch integrated mechanism.

[0050] 2) The power source is provided centrally, the configuration is more streamlined, the layout is more compact, and it is conducive to the layout of the rotary unit.

[0051] 3) The ship's operating conditions are complex, and each winch can be used flexibly according to actual needs, which improves the utilization rate of the diesel engine and has long-term economy.

[0052] 4) The diesel engine adopts air cooling, which can avoid special components such as power distribution slip rings and cooling water rotary joints, reducing the failure rate;

[0053] 5) The transmission from the power source to the end user is direct and efficient, which can reduce unnecessary energy conversion losses.

It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
