Description

Technical Field

[0001] The invention belongs to the technical field of ship unloaders, and in particular relates to a roll-on / roll-off steering device for a ship unloader. Background Art

[0002] The ro-ro steering device of the ship unloader is a steering device used when the ship unloader is towed from the transport ship to the user's terminal. Figure 1 As shown, the currently used roll-on / roll-off steering device for ship unloaders primarily consists of a ship unloader balance beam 100, a steering flange 200, a lifting beam 300, a lifting cylinder, a temporary support 400, and a temporary track 500. Its operating principle is that when unloading, the ship unloader is towed from the ship to a designated location on the temporary track 500, which is perpendicular to the user's terminal track. The ship unloader balance beam 100 is lifted using the lifting beam 300, the lifting cylinder, and the temporary support 400. The steering flange 200 is loosened, and the steering wheel assembly is steered. Once in position, the steering flange 200 is retightened, completing the unloader's steering. During the lifting process, all unloader loads are transferred to the user's terminal via the lifting cylinder. The load requirements for both the terminal's load-bearing points and the unloader's lifting points are high, and the limited lifting space places strict demands on the layout of the unloader's steering wheel assembly. Therefore, the lifting process must be slow, and the ship unloader must also be protected from wind. This makes the entire lifting and steering process time-consuming and risky.

[0032] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 2 to 7 As shown, the roll-on / roll-off steering device of the ship unloader of the present invention is laid on the dock track beam, and is characterized in that the roll-on / roll-off steering device of the ship unloader includes a ship unloader balance beam 1, a steering flange assembly 2, a steering wheel group 3, a bogie 4, a temporary tire frame 5, a transition beam 6 and a landing beam 7. The steering wheel group 3 is connected to the ship unloader balance beam 1 through the steering flange assembly 2, the steering wheel group 3 is rotatably arranged on the temporary tire frame 5 through the bogie 4, the transition beam 6 is arranged on one side of the temporary tire frame 5 and is connected to the upper track of the dock track beam, the landing beam 7 is arranged on the temporary tire frame 5, and the transport ship is connected to the temporary tire frame 5 through the landing beam 7, wherein:

[0034] The bogie 4 includes a cross beam 41, rollers 42, a steering shaft 43, a steering track 44 and a track connecting block 45. The rollers 42 are rotatably arranged at the lower end of the cross beam 41, the steering shaft 43 is arranged in the middle of the cross beam 41, the steering track 44 is arranged at the upper end of the cross beam 41, and the track connecting blocks 45 are arranged at both ends of the steering track 44.

[0035] The temporary tire frame 5 includes a longitudinal beam 51, a transverse beam 52, an annular beam 53 and a steering hole 54. The longitudinal beam 51 and the transverse beam 52 are arranged alternately, the annular beam 53 is arranged at the intersection of the longitudinal beam 51 and the transverse beam 52, and the steering hole 54 is arranged in the middle of the annular beam 53.

[0036] Furthermore, in the ship unloader roll-on / roll-off steering device of the present invention, the steering flange assembly 2 includes a ship unloader balance beam flange 21, a shear rotation shaft 22, a stainless steel pad 23, a tetrafluoroethylene pad 24, a steering wheel group flange 25 and a fixing bolt group 26. The ship unloader balance beam flange 21 is welded to the ship unloader balance beam 1, and the steering wheel group flange 25 is welded to the steering wheel group. The stainless steel pad 23 and the tetrafluoroethylene pad 24 are correspondingly arranged between the ship unloader balance beam flange 21 and the steering wheel group flange 25. The ship unloader balance beam flange 21 and the steering wheel group flange 25 can be connected by one of the shear rotation shaft 22 and the fixing bolt group 26. Since the friction coefficient between the stainless steel pad 23 and the tetrafluoroethylene pad 24 is very small, it is effectively ensured that the ship unloader balance beam flange 21 and the steering wheel group flange 25 can be easily rotated when connected through the shear rotation shaft 22.

[0037] Furthermore, in the roll-on / roll-off steering device of the ship unloader of the present invention, movable rails 55 are provided on the longitudinal beam 51 and the transverse beam 52, and the movable rails 55 match the steering rails 44. The movable rails 55 and the steering rails 44 are on the same horizontal plane, and a card slot 56 is provided between the longitudinal beam 51 and the transverse beam 52 and the cross beam 41.

[0038] Furthermore, in the roll-on / roll-off steering device of the ship unloader of the present invention, the track connecting block 45 is matched with the card slot 56, the track connecting block 45 is embedded in the card slot 56, and the movable track 55 is connected with the steering track 44 through the track connecting block 45, thereby effectively ensuring that the movable track 55 is connected with the steering track 44, and at the same time the cross beam 41 is locked with the longitudinal beam 51 and the transverse beam 52.

[0039] Furthermore, in the roll-on / roll-off steering device of the ship unloader of the present invention, the steering shaft 43 is matched with the steering hole 54, the steering shaft 43 is inserted into the steering hole 54, the roller 42 is matched with the annular beam 53, and the cross beam 41 is rollingly connected to the annular beam 53 through the roller 42, thereby effectively ensuring that the cross beam 41 can rotate around the annular beam 53, so that the ship unloader can be steered.

[0040] Furthermore, in the roll-on / roll-off steering device of the ship unloader of the present invention, one side of the transition beam 6 is inclined, and a transition track 61 is installed on the transition beam 6. One side of the transition track 61 is connected to the movable track 55, and the other side of the transition track 61 is connected to the track on the dock track beam, thereby effectively and safely and smoothly towing the ship unloader from the temporary tire frame 5 to the user's dock.

[0041] Furthermore, in the roll-on / roll-off steering device of the ship unloader of the present invention, the height of one end of the landing beam 7 is matched with the transport ship, and the height of the other end of the landing beam 7 is matched with the temporary tire frame 5. A landing track 71 is installed on the landing beam 7, and one end of the landing track 71 is connected to the movable track 55, and the other end of the landing track 71 is overlapped with the transport ship, thereby effectively ensuring that the ship unloader is smoothly towed from the transport ship to the temporary tire frame 5.

[0042] Specifically, when the ship unloader is unloading, the ship unloader is towed from the transport ship to the steering rail 44 via the landing rail 71 installed on the landing beam 7. At this time, the fixing bolt group 26 between the ship unloader balance beam flange 21 and the steering wheel group flange 25 is removed and connected using the shear rotation shaft 22. At the same time, the track connection block 45 in the slot 56 is removed. At this time, the steering shaft 43 rotates in the steering hole 54 to make the roller 42 roll along the annular beam 53. At the same time, the rotational force of the bogie 4 drives the steering wheel group flange 25 to rotate around the shear rotation shaft 22 through the steering wheel group 3, and the friction coefficient is reduced by the stainless steel pad 23 and the tetrafluoroethylene pad 24 between the ship unloader balance beam flange 21 and the steering wheel group flange 25, thereby quickly completing the steering of the steering wheel group 3. After the steering is completed, the ship unloader balance beam flange 21 and the steering wheel group flange 25 are connected by the fixing bolt group 26. The ship unloader can be safely moved to the user's terminal by towing through the transition rail 61 on the transition beam 6.

[0043] The temporary cradle 5 is laid on the user terminal track beam and can bear the entire weight of the ship unloader. All loads of the ship unloader are transferred to the user terminal track beam via the transverse beam 52. The transition beam 6 is laid on the user terminal track beam and can be connected to the longitudinal beam 51 or the transverse beam 52, allowing the ship unloader to be safely and smoothly towed from the temporary cradle 5 to the user terminal track. The landing beam 7 and track are set according to the elevation of the transport ship and the terminal, and can be connected to the longitudinal beam 51 or the transverse beam 52. The connection is opposite to the transition beam 6 (i.e., when the transition beam 6 is connected to the transverse beam 52, the landing beam 7 is connected to the longitudinal beam 51, and when the transition beam 6 is connected to the longitudinal beam 51, the landing beam 7 is connected to the transverse beam 52).

[0044] In summary, compared with the prior art, the roll-on / roll-off steering device of the ship unloader of the present invention has the following advantages and beneficial effects:

[0045] Planar steering is achieved through the cooperation of the bogie and the temporary tire frame, without the need for jacking, eliminating the jacking points of the ship unloader and the user's terminal, avoiding design restrictions and lowering design requirements; through the cooperation of the stainless steel pad and the tetrafluoroethylene pad, the friction coefficient is reduced, making the steering process smooth, time-saving, risk-free, safe and reliable.
