Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ships, in particular to a novel overbridge slewing device. Background Art
[0002] The floating dock has a U-shaped structure, and the dock walls on the left and right sides are far apart. In order to meet the personnel passage requirements on the top decks of the port and starboard sides, an overbridge structure is generally provided on each of the left dock wall and the right dock wall at the top of the floating dock. The overbridge of the floating dock is an important facility connecting the top decks of the floating dock.
[0003] During the process of a ship under repair entering the dock, the overbridge needs to be opened to avoid damage to the overbridge caused by the out-of-control entering ship. After the floating dock floats, in order to meet the personnel passage needs on both sides of the floating dock, the overbridge will rotate to the position in the middle of the ship and be locked. Due to the operating characteristics of the floating dock, the overbridge needs to be opened and closed frequently.
[0004] For opening and closing, a conventional floating dock needs to be provided with a towing eye plate on the overbridge body, and at the same time, equipment such as a winch and a fairlead are provided on the deck. When the overbridge needs to be opened and closed, the crew needs to connect the towing eye plate on the overbridge body with a steel wire rope, and pass the steel wire rope through the fairlead on the top deck and connect it to the winch. Thus, the overbridge is opened and closed by winding and unwinding the steel wire rope by the winch.
[0005] The prior art has the following defects:
[0006] 1. The conventional overbridge rotation realizes the opening and closing of the overbridge by the winch towing the steel wire rope. When the overbridge is not fixed, personnel need to go onto the overbridge for operation, which has certain dangers; moreover, every time the overbridge is opened and closed, the steel wire rope needs to be manually connected and unlocked, and the workload of the crew is large and extremely inconvenient.
[0007] 2. In order to tow the overbridge, equipment such as a winch and a fairlead need to be provided on the deck, which requires a large deck area. Moreover, setting up a special towing winch has a great impact on the cost. Content of the Utility Model
[0008] The technical problem to be solved by the utility model is to overcome the above defects existing in the prior art and provide a novel overbridge slewing device.
[0009] The utility model solves the above technical problem through the following technical solutions:
[0010] A novel overbridge slewing device, which includes an overbridge body arranged on the dock wall of the floating dock; a first support is fixedly arranged at the end of the dock wall, and the overbridge body is hinged to the first support; a crank is fixedly connected to the overbridge body; an oil cylinder base is fixedly arranged on the inner side wall of the dock wall; a hydraulic cylinder capable of rotating the overbridge body around the first support through the crank is arranged between the crank and the oil cylinder base; and two ends of the hydraulic cylinder are respectively hinged to the crank and the oil cylinder base.
[0011] Furthermore, a first rotating shaft is fixedly installed on the overpass body. The first rotating shaft passes through the first support member, and one end of the crank is fixedly connected to the first rotating shaft; the other end of the crank is hinged to the hydraulic cylinder.
[0012] Furthermore, a first bushing is arranged inside the first support member, and the first rotating shaft passes through the first bushing.
[0013] Furthermore, the first rotating shaft is vertically distributed.
[0014] Furthermore, a clearance fit is provided between the first rotating shaft and the first bushing.
[0015] Furthermore, both the crank and the hydraulic cylinder are arranged below the top deck of the floating dock.
[0016] Furthermore, a second support member is fixedly installed at the end of the dock wall. The second support member is arranged below the first support member; the lower end of the overpass body is hinged to the second support member.
[0017] Furthermore, a second rotating shaft is fixedly installed on the overpass body; a second bushing is arranged inside the second support member, and the second rotating shaft passes through the second bushing.
[0018] Furthermore, the second rotating shaft is vertically distributed.
[0019] Furthermore, the rotation axis lines of the first rotating shaft and the second rotating shaft coincide.
[0020] The beneficial effects of the present utility model are as follows: For the overpass rotating device of the present utility model, when the overpass is opened and closed, the crew does not need to connect the steel wire rope between the top deck and the overpass body; moreover, the operation of the overpass rotating device can be completed by operating the start and stop of the hydraulic pump station on the top deck of the dock wall. Therefore, the manual operation of opening and closing the overpass can be greatly reduced, the safety of opening and closing the overpass can be improved, and the operation of the crew can be made safer. In the present utility model, since both the crank and the hydraulic cylinder device are located below the top deck, it does not affect the layout of the deck equipment and saves the deck space. For the novel overpass rotating device of the present utility model, there is no need to specially set up equipment such as a traction winch and a fairlead, which also reduces the impact on the deck equipment and saves costs.

[0027] The following is a preferred embodiment, and the present utility model will be described more clearly and completely in conjunction with the accompanying drawings.
[0028] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, a new type of overpass rotary device includes an overpass bridge body 10 provided on the dock wall 20 of a floating dock; a first support member 31 capable of supporting the overpass bridge body is fixedly provided at the end of the dock wall 20, and the overpass bridge body 10 is hinged to the first support member 31.
[0029] A crank 11 is fixedly connected to the overpass bridge body 10; an oil cylinder base 21 is fixedly provided on the inner side wall of the dock wall 20.
[0030] A hydraulic cylinder 12 capable of rotating the overpass bridge body around the first support member through the crank is provided between the crank 11 and the oil cylinder base 21; both ends of the hydraulic cylinder 12 are respectively hinged to the crank 11 and the oil cylinder base 21.
[0031] Both the crank 11 and the hydraulic cylinder 12 are provided below the top deck 22 of the floating dock.
[0032] A first rotating shaft 41 is fixedly provided at the upper end of the overpass bridge body 10, and the first rotating shaft 41 is vertically distributed.
[0033] The first rotating shaft 41 penetrates through the first support member 31, and one end of the crank 11 is fixedly connected to the first rotating shaft 41; the other end of the crank 11 is hinged to the hydraulic cylinder 12.
[0034] A first bushing 51 is provided in the first support member 31, and the first rotating shaft 41 penetrates through the first bushing 51. A clearance fit is provided between the first rotating shaft 41 and the first bushing 51.
[0035] A second support member 32 is fixedly provided at the end of the dock wall 20, and the second support member 32 is provided below the first support member 31; the lower end of the overpass bridge body 10 is hinged to the second support member 32.
[0036] The overpass bridge body 10 is fixedly provided with a second rotating shaft 42; the second rotating shaft 42 is vertically distributed. A second shaft sleeve (not shown in the figure) is provided inside the second support member 32, and the second rotating shaft 42 is inserted through the second shaft sleeve. A clearance fit is adopted between the second rotating shaft and the second shaft sleeve.
[0037] The rotation axis line of the first rotating shaft 41 coincides with the rotation axis line of the second rotating shaft 42.
[0038] The overpass bridge body is supported by the first support member and the second support member together. The first rotating shaft and the second rotating shaft are both fixedly connected to the overpass bridge body. The first support member and the second support member are respectively provided with a first shaft sleeve and a second shaft sleeve.
