The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships are changed accordingly.

A dry dock docking system according to an embodiment of the present invention will be described first in detail with reference to the accompanying drawings.

As shown in fig. 1, the dry dock docking system according to an embodiment of the present invention for towing a ship 300 from a sea side into a dry dock land side includes: two traction rails 100, two traction winches 200, a traction rope 201 and a rigging 211.

Wherein two traction rails 100 are adapted to be symmetrically disposed on either side of the dry dock. The two traction winches 200 are arranged symmetrically at the end of the two traction rails 100 facing the land side. The two rail trolleys 210 are respectively symmetrically arranged on the traction rail 100. The traction rope 201 connects the traction winch 200 and the rail car 210 so that the rail car 210 moves along the traction rail 100 under the traction of the traction winch 200. That is to say, the two rail cars 210 can be synchronously advanced to the land side on the two traction rails 100 under the traction of the traction winch 200.

One end of the rigging 211 is connected to the trolley 210 and the other end is used to connect to the vessel 300. That is, the two traction winches 200 do not directly contact the vessel 300 when towing the vessel 300.

Therefore, according to the dry dock docking system provided by the embodiment of the invention, because the traction winch 200 and the rail trolley 210 are symmetrically arranged on the traction rail 100, in the process that the traction winch 200 is connected with the rail trolley 210 through the traction rope 201 to pull the ship 300 from the sea side to the dry dock land side, the force on two sides of the rigging 211 connected with the ship 300 on the rail trolley 210 is balanced, the influence of the sea state on the posture of the ship 300 is reduced, and the risk of the ship 300 shifting is effectively reduced. In addition, the traction winch 200 is not in direct contact with the ship 300, and the rigging 211 can be directly abandoned in case of emergency, so that the safety is effectively improved.

As shown in fig. 2, in the dry dock docking system according to the embodiment of the present invention, a towing rail 100 includes: a fixed seat 101 and a sliding track 102. The fixed seat 101 is used for fixing concrete embedded in a dry dock; the sliding rail 102 is a pulley rail and is used for being welded with the fixing seat 101. Of course, the connection mode between the sliding rail 102 and the fixed seat 101 may be a riveting connection, besides welding. The sliding track 102 is a T-shaped structure and is slidably connected to the small rail car 210, and the small rail car 210 includes two sets of positioning wheel sets symmetrically arranged on the side and a traveling wheel set under the car body. When the rail trolley 210 runs on the sliding rail 102, the two sets of positioning wheel sets on the side edges are used for firmly positioning the rail trolley 210 on the sliding rail 102 on the side edges of the sliding rail 102, so that derailment of the rail trolley 210 can be prevented. Of course, the moving track may also be a gear track in addition to a pulley track, with the upper surface of the glide track 102 sloping towards the side facing away from the dry dock.

Therefore, according to the dry dock docking ship guiding system provided by the embodiment of the invention, the embedded type traction rail 100 is adopted, so that the concrete layer and the sliding rail 102 form an integral structure, the risk of deformation of the traction rail 100 during traction is reduced, and the service life of the traction rail 100 is prolonged. In addition, due to the adoption of the inclined embedded installation mode, the sliding rail 102 is better attached to the trolley 210, so that the stress of the sliding rail 102 is uniform, the risk of derailing the trolley 210 is effectively reduced, and the construction safety is improved.

According to one embodiment of the invention, the hauling rope 201 is a steel rope. Thereby, the strength of the hauling rope 201 can be ensured when the hauling winch 200 hauls the vessel 300, reducing the risk of breaking.

Further, the rigging 211 is a cable.

Further, as shown in fig. 3, the rail car 210 includes: a cable guide pile 212 and an emergency release hook 213. The fairlead 212 is disposed at an end of the rail car 210 near the vessel 300 and is used to position the rigging 211. The fairlead 212 may change the direction of the rigging 211 force as the trolley 210 tows the vessel 300 so that the force is directed toward the towing winch 200. Thus, the towing winch 200 can smoothly tow the ship 300 into the dry dock. The emergency release hook 213 is provided at an end of the rail car 210 remote from the vessel 300 and is used to lock the rigging 211, and in addition, the emergency release hook 213 can rapidly discard the rigging 211 in case of an emergency. Therefore, the traction work safety is effectively improved.

According to one embodiment of the invention, the traction winch 200 comprises: a tension measuring device and a rope length detecting device. The tension measuring device is used for measuring the tension of the traction rope 201; the rope length detection device is used for measuring the pulling length of the traction rope 201. From this, at the traction in-process, whether the traction force that tension measuring device and rope length detection device can detect ship both sides and receive is balanced, and then can early warning in advance, guarantees that both sides haulage rope 201 length is the same and traction force that receives is the same all the time, has avoided because the uneven risk that breaks or ship 300 takes place to squint of haulage rope 201 atress when ship 300 takes place to squint.

In one embodiment of the present invention, the graving dock docking system further comprises:

and a controller for controlling the tension and the pull-out length of the two hauling ropes 201 to be consistent during the hauling winch 200 hauling the vessel 300.

In one embodiment of the present invention, the graving dock docking system further comprises: the guide device 220, the guide device 220 is arranged on the traction track 100 between the rail trolley 210 and the traction winch 200, and the traction rope 201 is arranged in the guide device 220 in a penetrating way.

According to an embodiment of the present invention, the guiding device 220 further comprises:

the positioning roller set 221 and the traction rope 201 are arranged in the positioning roller set 221 in a penetrating mode. In the process that the traction winch 200 pulls the ship 300, the traction rope 201 is easy to shift when the traction rope 201 is recovered due to the wide reel of the traction winch 200, so that the recovered traction rope 201 is tangled, and the positioning roller sets 221 in the guiding device 220 limit the shift angle of the traction rope 201 through the up-and-down symmetrical rollers. Therefore, the service life of the traction rope 201 is effectively prolonged.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
