Description

Hammer winch for large-scale piling ship
Technical Field
The invention belongs to the technical field of marine equipment, and particularly relates to a hammer winch for a large-scale piling ship.
Background
A hammer winch for a piling ship generally adopts a duplex winding drum, a single internal expansion type clutch and a single hydraulic brake, a hydraulic motor drives the winding drum to rotate through a gear pair to achieve cable winding and unwinding operation, and all parts are installed on a common base to form a whole.
The hammer winch has large working load, and the single internal expansion clutch and the single hydraulic brake are adopted, so that the structural sizes of the internal expansion clutch, the hydraulic brake and the reel hub are very large, the proportion is very inconsistent compared with that of a reel, and the internal expansion clutch has too large structural size, so that the installation and the debugging are very inconvenient, and the maintenance after the use of a real ship is very inconvenient.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a hammer winch for a large piling ship, which reduces the sizes of an internal expansion clutch, a hydraulic brake and a reel hub to be matched with the size of a reel, and is convenient to install and debug.
The invention provides a hammer winch for a large-scale piling ship, which comprises a main shaft (3), wherein a large gear is connected to the main shaft (3) through a spline, the large gear is connected with two hydraulic motors (1) through a pair of gear pairs (2), two ends of the main shaft (3) are respectively sleeved with an internal expansion clutch (4), a hub of the internal expansion clutch (4) is connected with the main shaft (1) through a spline, an external friction belt of the internal expansion clutch (4) is attached to the inner surface of a hub (5) of a duplex winding drum, the duplex winding drum (6) is sleeved on the main shaft (3) in an empty mode, and is separated and reunion with the main shaft (3) through the internal expansion clutch (4).
As a further technical scheme of the invention, an output shaft of the hydraulic motor (1) is sleeved with a pinion, the pinion is connected with a bull gear through a gear pair (2), and the middle end of a main shaft (3) is sleeved with a ratchet and pawl device (7).
Furthermore, the outer surface of the duplex type winding drum hub (5) is connected with a hydraulic brake (8).
Furthermore, the main shaft (3), the internal expansion clutch (4) and the duplex type winding drum hub (5) are fixed on a common base (9).
The invention has the advantages that the device adopts the structure of the double internal expansion type clutch and the double hydraulic brake, can effectively reduce the structural sizes of the internal expansion type clutch, the hydraulic brake and the reel hub to be matched with the size of the reel, is convenient to install and debug, and is very convenient to maintain after the actual ship is used.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
Referring to fig. 1, the embodiment provides a hammer winch for a large pile driving vessel, which includes a main shaft 3, a large gear spline-connected to the main shaft 3, the large gear spline-connected to two hydraulic motors 1 through a pair of gear pairs 2, inner expanding clutches 4 respectively sleeved at two ends of the main shaft 3, a hub of the inner expanding clutch 4 spline-connected to the main shaft 1, an outer friction belt of the inner expanding clutch 4 attached to an inner surface of a hub 5 of a duplex drum, and the duplex drum 6 loosely sleeved on the main shaft 3 and clutched to the main shaft 3 through the inner expanding clutch 4.
The output shaft of the hydraulic motor 1 is sleeved with a pinion which is connected with a bull gear through a gear pair 2, and the middle end of the main shaft 3 is sleeved with a ratchet wheel and pawl device 7.
The outer surface of the duplex drum hub 5 is connected with a hydraulic brake 8.
The main shaft 3, the internal expansion clutch 4 and the duplex type reel hub 5 are fixed on a common base 9.
Two hydraulic motors 1 drive a big gear on a main shaft to rotate through a gear pair 2, the big gear drives a main shaft 3 to rotate, and the main shaft 3 drives a duplex type winding drum 6 to rotate through an internal expansion type clutch 4. The big gear is connected with the main shaft 3 by a spline. The hub of the internal expansion clutch 4 is connected with the main shaft 3 by a spline, and the external friction belt of the internal expansion clutch 4 is attached to the inner surface of the duplex drum hub 5. The duplex winding drum 6 is sleeved on the main shaft 3 in an empty mode, and is in clutch with the main shaft 3 through the internal expansion clutch 4, when the internal expansion clutch 4 is closed, the duplex winding drum 6 rotates along with the main shaft 3, and when the internal expansion clutch 4 is disengaged, the duplex winding drum 6 is disengaged from the main shaft 3.
After the structure of this device adoption two internal expanding clutch and two hydraulic brake, can effectively reduce internal expanding clutch, hydraulic brake and reel wheel hub's structural dimension, make it and reel size phase-match, simultaneously, be convenient for installation and debugging, and the maintenance after the real ship uses is very convenient.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to further illustrate the principles of the invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention, which is intended to be protected by the appended claims. The scope of the invention is defined by the claims and their equivalents.
