Description

Technical Field

[0001] The utility model relates to the technical field of teaching aids, in particular to a teaching device for simulating ship mooring. Background Art

[0002] When a ship docks, it is tied to a mooring post by a cable to ensure stable docking. The force mainly relies on the static friction between the cables. Therefore, during the mooring process, the more turns the cable makes, the larger the contact area and the greater the force. The number of turns required for the cable depends on the load on the cable, which can generally be calculated.

[0003] The teaching device for simulating ship mooring can simulate the actual scenario when a ship docks and moors, and has a positive effect on improving students' practical ability and cultivating students' learning interest. However, in the existing teaching devices for simulating ship mooring, they are all fixed, and the cable can only pass through in a fixed direction. In reality, the height, force direction, and force magnitude of the cable may be different each time a ship is moored, and the teaching device cannot well restore the real situation during mooring. Summary of the Utility Model

[0004] Aiming at the above deficiencies existing in the prior art, the technical problem to be solved by the utility model is to propose a teaching device for simulating ship mooring that is closer to the actual situation, has a good simulation effect, and is convenient for mooring.

[0005] The technical solution adopted by the utility model to solve its technical problems is to propose a teaching device for simulating ship mooring, including:

[0006] A base, on which a mooring post is provided. The mooring post includes a first upright post and a second upright post arranged at intervals.

[0007] A universal navigator, including a mounting body, a first pulley, and a second pulley. The mounting body is rotatably mounted on the base. The first pulley and the second pulley are arranged side by side on the mounting body, and there is a gap for the cable to pass through between the first pulley and the second pulley. There is a channel for the cable to pass through on the mounting body, and the channel is communicated with the gap.

[0008] The cable can bypass the first pulley or the second pulley, pass through the gap and the channel, and wind around the mooring post.

[0009] Further, the mounting body can rotate 360 degrees around the channel as the rotation center.

[0010] Further, the gap is directly opposite to the channel.

[0011] Further, a front limiting portion and a rear limiting portion are respectively provided on the installation main body, and the front limiting portion and the rear limiting portion can respectively limit the front-back movement of the installation main body relative to the base.

[0012] Further, the first pulley and the second pulley are both rotatably installed on the installation main body.

[0013] Further, a transverse stop bar is provided between the first upright post and the second upright post, and the transverse stop bar and the first upright post as well as the second upright post form a double-cross mooring bitt.

[0014] Further, the rotation center of the installation main body is perpendicular to the transverse stop bar.

[0015] Further, when the cable rope winds around the mooring bitt, the transverse stop bar can limit the cable rope.

[0016] Further, both ends of the transverse stop bar respectively extend out from the sides of the first upright post and the second upright post, and the diameter of the transverse stop bar is smaller than the diameters of the first upright post and the second upright post.

[0017] Further, both ends of the transverse stop bar are provided with first limiting rings, and the tops of both the first upright post and the second upright post are provided with second limiting rings.

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:

[0019] In the utility model, a universal fairlead is arranged on the base. Among them, the installation main body of the universal fairlead is rotatably installed on the base, and its angle can be adjusted arbitrarily. During the process of mooring the cable rope, the cable rope can pass through the universal fairlead from various angles, and it can automatically adjust the rotation angles of the mounting seat, the first pulley and the second pulley according to the actual stress condition of the cable rope, which is more close to the actual use situation and has a good simulation effect.

[0030] As Figures 1 - 3 shown, a teaching device for simulating ship mooring mainly includes: a base 1 and a universal fairlead 2, and a bollard 10 is provided on the base 1.

[0031] A mooring bitt 10 is provided on a base 1. The mooring bitt 10 includes a first upright post 101 and a second upright post 102 which are arranged at intervals. Both the first upright post 101 and the second upright post 102 are perpendicular to the base 1. The cable can be wound in a figure-eight loop between the first upright post 101 and the second upright post 102. Compared with other winding methods, winding in a figure-eight loop can effectively increase the contact area of the cable, thereby improving the static friction of the cable. Under the condition of the same load, the number of loops required for winding in a figure-eight loop is the least, that is, it can meet the force requirements. Among them, a transverse stop bar 103 is provided between the first upright post 101 and the second upright post 102. The transverse stop bar 103 is preferably integrally formed with the first upright post 101 and the second upright post 102, and the transverse stop bar 103 and the first upright post 101 and the second upright post 102 form a double-cross mooring bitt 10. When mooring, the cable winds around the mooring bitt 10, and the transverse stop bar 103 can limit the cable, and the transverse stop bar 103 can prevent the cable from slipping off the first upright post 101 and the second upright post 102.

[0032] Among them, both ends of the transverse stop bar 103 extend out from the sides of the first upright post 101 and the second upright post 102 respectively, and the diameter of the transverse stop bar 103 is smaller than the diameters of the first upright post 101 and the second upright post 102. Both ends of the transverse stop bar 103 have first limit rings 103A. When the cable winds around the transverse stop bar 103, the first limit rings 103A can limit the cable to prevent the cable from shifting on the transverse stop bar 103. The tops of both the first upright post 101 and the second upright post 102 have second limit rings 101A. The setting of the second limit rings 101A can prevent the cable from detaching from the tops of the first upright post 101 and the second upright post 102, ensuring reliable mooring.

[0033] A universal navigator, including an installation main body 20, a first pulley 21 and a second pulley 22. The installation main body 20 is rotatably installed on the base 1. The first pulley 21 and the second pulley 22 are arranged side by side on the installation main body 20. Both the first pulley 21 and the second pulley 22 are rotatably installed on the installation main body 20, and there is a gap 210 for the cable to pass through between the first pulley 21 and the second pulley 22; there is a channel 201 for the cable to pass through on the installation main body 20, and the channel 201 is communicated with the gap 210. The gap 210 is directly opposite to the channel 201, and the reverse extension line of the channel 201 is at the middle part of the transverse stop bar 103, which is convenient for the cable to wind around it. During the actual mooring process, the cable can wind around the first pulley 21 or the second pulley 22, pass through the gap 210 and the channel 201, and wind around the mooring bitt 10, and can wind multiple loops on the mooring bitt 10.

[0034] Specifically, a horizontally arranged circular hole is provided on the base 1. The installation main body 20 is rotatably installed in the circular hole. The channel 201 on the installation main body 20 is also a circular hole. Therefore, it is equivalent to that the installation main body 20 can rotate 360 degrees with the channel 201 as the rotation center to adapt to the direction of the cable. The rotation direction of the installation main body 20 is perpendicular to the horizontal cross bar 103. A front limit part 202 and a rear limit part 203 are respectively provided on the installation main body 20. The front limit part 202 and the rear limit part 203 can be separately arranged from the installation main body 20, and both can be in movable contact with the base 1, so that the front limit part 202 and the rear limit part 203 can respectively limit the forward and backward movement of the installation main body 20 relative to the base 1. The front limit part 202 and the rear limit part 203 are preferably limit flanges, and their diameters are larger than the diameter of the circular hole on the base 1, which can also ensure that the installation main body 20 will not break away from the base 1.

[0035] During the use process, one end of the cable is connected to the load. After the other end of the cable bypasses the fixed pulley, it enters through the gap 210 between the first pulley 21 and the second pulley 22, bypasses either the first pulley 21 or the second pulley 22, and passes out of the universal cable guide 2 through the channel 201 on the installation main body 20. The universal cable guide 2 can adaptively adjust the rotation angle of the installation main body 20 according to the direction of the cable and the direction of the force. After the cable passes out of the channel 201, it makes a figure-eight loop around the bollard 10, and can make multiple figure-eight loops until the static friction force of the cable is sufficient to bear the load of the cable.

[0036] Preferably, in order to facilitate the movement of this teaching device, a plurality of foldable wheels can be provided at the bottom of the base 1. When the teaching device needs to be moved, the wheels are unfolded downward, and the teaching device can be directly pushed. When it is not necessary to move, the wheels can be folded up without affecting the normal use of the teaching device.

[0037] In this solution, a universal cable guide 2 is provided on the base 1. Among them, the installation main body 20 of the universal cable guide 2 is rotatably installed on the base 1 and can rotate 360 degrees, and the angle can be adjusted arbitrarily. During the cable mooring process, the cable can pass through the universal cable guide 2 from various angles. It can automatically adjust the rotation angles of the installation seat, the first pulley 21 and the second pulley 22 according to the actual force condition of the cable, which is closer to the actual use situation and has a good simulation effect.
