Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a novel overhead bridge rotating device. Background Art

[0002] The floating dock is a U-shaped structure, with the left and right dock walls far apart. In order to meet the requirements for the passage of personnel on the left and right top decks, a bridge structure is generally set on the left and right dock walls on the top of the floating dock. The floating dock bridge is an important facility connecting the top deck of the floating dock.

[0003] During the docking process, the bridge must be opened to prevent the docking ship from losing control and damaging the bridge. After the floating dock is floated, the bridge will be rotated back to the middle of the ship and locked to meet the needs of personnel passing through the dock walls on both sides of the floating dock. Due to the characteristics of floating dock operations, the bridge needs to be opened and closed frequently.

[0004] In order to open and close, conventional floating docks need to install traction eye plates on the bridge body, and also install winches, fairleads and other equipment on the deck. When the bridge needs to be opened and closed, the crew needs to connect the traction eye plates on the bridge body with steel wire ropes, and pass the steel wire ropes through the fairleads on the top deck to connect with the winches. The bridge is opened and closed by retracting and releasing the steel wire ropes by the winches.

[0005] The prior art has the following defects:

[0006] 1. Conventional bridge rotation is achieved by winch pulling wire rope to open and close the bridge. When the bridge is not fixed, personnel need to go on the bridge to work, which is dangerous. Moreover, each time the bridge is opened and closed, the wire rope needs to be manually connected and unlocked, which is very inconvenient and heavy workload for the crew.

[0007] 2. In order to tow the flyover, winches, fairleads and other equipment need to be installed on the deck, which requires a large deck area. Moreover, the installation of a special towing winch has a great impact on the cost. Summary of the invention

[0008] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a new type of overpass rotating device.

[0009] The present invention solves the above technical problems through the following technical solutions:

[0010] A novel overpass rotating device comprises an overpass body arranged on the dock wall of a floating dock; a first support member is fixedly arranged at the end of the dock wall, and the overpass body is hinged to the first support member; a crank is fixedly connected to the overpass body; a cylinder base is fixedly arranged on the inner side wall of the dock wall; a hydraulic cylinder is arranged between the crank and the cylinder base, and can rotate the overpass body around the first support member through the crank; and the two ends of the hydraulic cylinder are respectively hinged to the crank and the cylinder base.

[0011] Furthermore, a first rotating shaft is fixedly provided on the bridge body of the overpass, the first rotating shaft is passed through the first supporting member, one end of the crank is fixedly connected to the first rotating shaft; and the other end of the crank is hinged to the hydraulic cylinder.

[0012] Furthermore, a first sleeve is provided in the first support member, and the first rotating shaft passes through the first sleeve.

[0013] Furthermore, the first rotating shaft is distributed vertically.

[0014] Furthermore, there is a clearance fit between the first rotating shaft and the first sleeve.

[0015] Furthermore, the crank and the hydraulic cylinder are both arranged below the top deck of the floating dock.

[0016] Furthermore, a second support member is fixedly provided at the end of the dock wall, and 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 provided on the bridge body of the overpass; a second shaft sleeve is provided in the second supporting member, and the second rotating shaft passes through the second shaft sleeve.

[0018] Furthermore, the second rotating shaft is distributed vertically.

[0019] Furthermore, the rotation axis centerline of the first rotating shaft coincides with the rotation axis centerline of the second rotating shaft.

[0020] The beneficial effects of the present invention are as follows: with the overpass slewing device of the present invention, the crew does not need to connect the steel wire rope between the top deck and the overpass body when the overpass is opened and closed; and the overpass slewing device can be operated by operating the hydraulic pump station on the top deck of the dock wall to start and stop, thus greatly reducing the manual operation of the overpass opening and closing, improving the safety of the overpass opening and closing, and making the crew's operation safer. In the present invention, since the crank and the hydraulic cylinder device are both located below the top deck, the deck equipment layout is not affected, saving deck space. The new overpass slewing device of the present invention does not need to specially set up traction winches, fairleads and other equipment, which also reduces the impact on the deck equipment and saves costs.

[0027] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a novel overpass slewing device comprises an overpass body 10 arranged on a dock wall 20 of a floating dock; a first support member 31 capable of supporting the overpass body is fixedly provided at the end of the dock wall 20, and the overpass body 10 is hinged to the first support member 31.

[0029] A crank 11 is fixedly connected to the bridge body 10 ; and a cylinder base 21 is fixedly arranged on the inner side wall of the dock wall 20 .

[0030] A hydraulic cylinder 12 is provided between the crank 11 and the cylinder base 21 , which can rotate the bridge body around the first support member through the crank; two ends of the hydraulic cylinder 12 are hinged to the crank 11 and the cylinder base 21 respectively.

[0031] The crank 11 and the hydraulic cylinder 12 are both arranged 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 body 10 , and the first rotating shaft 41 is vertically distributed.

[0033] The first rotating shaft 41 passes through the first supporting member 31 , 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 sleeve 51 is disposed in the first support member 31, and the first rotating shaft 41 passes through the first sleeve 51. The first rotating shaft 41 and the first sleeve 51 are clearance-fitted.

[0035] A second support member 32 is fixedly provided at the end of the dock wall 20 , and the second support member 32 is arranged below the first support member 31 ; the lower end of the overpass body 10 is hinged to the second support member 32 .

A second sleeve (not shown in the figure) is arranged inside the second support member 32, and the second rotating shaft 42 is passed through the second sleeve. There is a clearance fit between the second rotating shaft and the second sleeve.

[0037] The rotation axis center line of the first rotating shaft 41 coincides with the rotation axis center line of the second rotating shaft 42 .

[0038] The bridge body of the overpass is supported by a first support member and a second support member, and the first rotating shaft and the second rotating shaft are both fixedly connected to the bridge body of the overpass. The first support member and the second support member are respectively equipped with a first sleeve and a second sleeve.
