Description

Technical Field

[0001] This utility model belongs to the field of ship berthing monitoring technology, and in particular relates to a ship berthing monitoring device. Background Technology

[0002] Terminal companies are primarily responsible for loading and unloading operations. With the increasing workload, the safety management of ship berthing is of paramount importance. Traditional methods of ship berthing, relying mainly on pilots and terminal dispatchers, are no longer sufficient to meet the safe berthing needs of large vessels, posing a safety hazard of ship collisions with the terminal and shore-side equipment. To monitor the distance between the ship and the quayside, each berth is typically equipped with two laser rangefinders: one aimed at the bow of the berthing vessel, and the other at the stern.

[0003] Existing laser rangefinders primarily rely on manual adjustment for height positioning. To achieve automatic adjustment, a dock laser berthing monitoring device, disclosed in application number CN2018219714401, is proposed. This device includes a controller and two sets of dock laser berthing monitoring units. Each unit comprises a take-up / release reel, a take-up / release reel bracket, a drive motor, a fixed pulley, a laser rangefinder, and a laser rangefinder mounting base. The take-up / release reel is mounted on the take-up / release reel bracket. The drive motor is connected to the take-up / release reel and drives it to rotate forward or backward. The fixed pulley is located diagonally above the take-up / release reel and is fixedly installed. The laser rangefinder is mounted on the laser rangefinder mounting base. A pull rope for pulling the laser rangefinder mounting base is wound around the take-up / release reel and passes over the fixed pulley. The drive motor and the laser rangefinder are connected to the controller via wiring. This technical solution sends commands to the drive motor through the controller, which in turn drives the take-up and release reels to automatically adjust the height of the laser rangefinder, offering advantages such as timeliness and high accuracy.

[0004] Due to the complex and changeable natural environment of the dock, including extreme wind and rain, the laser rangefinder and its mounting base are generally designed to be heavy to ensure stability and good wind resistance. However, since the laser rangefinder and its mounting base are attached to the end of the pull rope, they always exert a large downward force on the rope, causing the drive motor and the pull rope to bear a large load. Prolonged high-load operation can easily lead to drive motor failure, and reliability needs to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a ship berthing monitoring device with good reliability and suitable for long-term use.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a ship berthing monitoring device, including a drive mechanism, two slide rails and a monitoring unit. The drive mechanism is fixedly installed on the dock ground. The two slide rails are fixedly installed on the side of the dock facing the sea and are symmetrically distributed from left to right. The monitoring unit is located between the two slide rails and slides up and down with the slide rails. The drive mechanism is used to drive the monitoring unit to slide up and down. The monitoring unit includes a base plate, a back plate and a laser rangefinder. The laser rangefinder is installed on the base plate. The rear side of the base plate is fixedly connected to the lower end of the back plate. The rear side of the back plate is provided with a plurality of sliding wheels that cooperate with the slide rails and a locking mechanism for locking with the slide rails. The locking mechanism is located below all the sliding wheels.

[0007] Preferably, the locking mechanism includes a bidirectional telescopic cylinder, which is connected to the back plate via a connecting plate. A limit rod is fixedly provided on the piston rod of the bidirectional telescopic cylinder, and multiple limit holes are provided on the slide rails distributed in the vertical direction. The multiple limit holes on the two slide rails are symmetrically distributed from left to right. The bidirectional telescopic cylinder is used to drive the two limit rods to pass through the two symmetrically distributed limit holes or separate from the limit holes.

[0008] Preferably, one end of the limiting rod is fixedly connected to the piston rod of the bidirectional telescopic cylinder, and the other end of the limiting rod is provided with an inclined guide surface that slopes downward from the outside to the inside. When the limiting rod passes through the limiting hole, the inclined guide surface is offset from the limiting hole.

[0009] Preferably, the drive mechanism includes a base, a bracket, a reel, a drive motor, and a traction rope. The base is fixedly mounted on the dock ground, the bracket is fixedly mounted on the base, the reel is rotatably mounted on the bracket, the drive motor is mounted on one side of the bracket and is used to drive the reel to rotate, one end of the traction rope is connected to the reel, and the other end of the traction rope is connected to the upper end of the back plate.

[0010] Preferably, the lower end of the connecting plate is fixedly provided with two support plates, and the two support plates correspond one-to-one with the two limiting rods. The support plates are provided with shaft holes, and the limiting rods pass through the corresponding shaft holes.

[0011] Preferably, the system also includes a protective cover disposed on the top of the slide rail. The protective cover has a perforation and a first fixed pulley on the side facing the drive mechanism. A second fixed pulley is disposed on the inner top surface of the protective cover. The other end of the traction rope passes through the first fixed pulley, the perforation, and the second fixed pulley and is connected to the upper end of the back plate. When the drive mechanism drives the monitoring unit to slide upward to the top of the slide rail, the monitoring unit enters the protective cover.

[0012] Preferably, the protective cover has symmetrically distributed clearance grooves on its side, which correspond to the uppermost limiting hole. The limiting rod passes through the uppermost limiting hole and extends into the clearance groove.

[0013] Preferably, the protective cover has a transparent observation window on its side.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] 1. By adding a locking mechanism, after the position of the monitoring unit is adjusted, the locking mechanism and the slide rail lock together, which not only helps to improve the stability of the structure, but also helps to reduce the load on the drive motor, reduce the risk of drive motor failure, and has good reliability, making it suitable for long-term use;

[0016] 2. By setting up a protective cover, the monitoring unit can be slid up into the protective cover in extreme wind and rain weather, or when the monitoring unit is not in use, to reduce the impact of the external environment on the monitoring unit and protect the monitoring unit.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] Example 1: As Figures 1 to 3 As shown, a ship berthing monitoring device includes a drive mechanism 1, two slide rails 2 and a monitoring unit 3. The drive mechanism 1 is fixedly installed on the dock ground. The two slide rails 2 are fixedly installed on the side of the dock facing the sea and are symmetrically distributed from left to right. The monitoring unit 3 is located between the two slide rails 2 and slides up and down with the slide rails 2. The drive mechanism 1 is used to drive the monitoring unit 3 to slide up and down.

[0026] In this embodiment, the monitoring unit 3 includes a base plate 31, a back plate 32, and a laser rangefinder 33. The laser rangefinder 33 is mounted on the base plate 31. The rear side of the base plate 31 is fixedly connected to the lower end of the back plate 32. The base plate 31 and the back plate 32 cooperate to form an L-shape. The rear side of the back plate 32 is provided with a plurality of sliding wheels 34 that cooperate with the slide rail 2, and a locking mechanism 4 for locking with the slide rail 2. The locking mechanism 4 is located below all the sliding wheels 34.

[0027] In this embodiment, the slide rail 2 has a U-shaped cross section, with the opening 21 facing the area between the two slide rails 2. The sliding wheel 34 extends into the opening 21 of the slide rail 2, and the rear side of the back plate 32 rests on the front end surface of the slide rail 2 so that the two fit together tightly.

[0028] Example 2: Figures 2 to 4 As shown, the rest of the components are the same as in Embodiment 1, except that the locking mechanism 4 includes a bidirectional telescopic cylinder 41. The bidirectional telescopic cylinder 41 is connected to the back plate 32 via a connecting plate 43. A limit rod 42 is fixedly installed on the piston rod of the bidirectional telescopic cylinder 41. Multiple limit holes 22 are provided on the slide rail 2, distributed vertically. The multiple limit holes 22 on the two slide rails 2 are symmetrically distributed horizontally. The bidirectional telescopic cylinder 41 is used to drive the two limit rods 42 to pass through the two symmetrically distributed limit holes 22 or to separate from the limit holes 22. The bidirectional telescopic cylinder 41 is located at the lower end of the connecting plate 43. When the limit rod 42 passes through the limit hole 22, the monitoring unit 3 is locked and cannot slide up or down; when the limit rod 42 disengages from the limit hole 22, the monitoring unit 3 is unlocked and can slide up and down.

[0029] In this embodiment, one end of the limiting rod 42 is fixedly connected to the piston rod of the bidirectional telescopic cylinder 41, and the other end of the limiting rod 42 is provided with an inclined guide surface 421 that slopes downward from the outside to the inside. When the limiting rod 42 passes through the limiting hole 22, the inclined guide surface 421 is offset from the limiting hole 22. First, the setting of the inclined guide surface 421 helps the limiting rod 42 to accurately pass through the limiting hole 22. At the same time, during use, the inclined guide surface 421 can also be used to slightly raise the monitoring unit 3. At this time, the pressure generated by the monitoring unit 3 acts on the slide rail 2 through the bidirectional telescopic cylinder 41 and the limiting rod 42, which greatly reduces the load on the drive motor 14 and helps to extend the service life of the drive motor 14.

[0030] Example 3: Figures 2 to 4 As shown, the rest is the same as in Embodiment 2, except that two support plates 44 are fixedly installed at the lower end of the connecting plate 43. The two support plates 44 correspond one-to-one with two limiting rods 42. The support plates 44 are provided with shaft holes 441, and the limiting rods 42 pass through the corresponding shaft holes 441. Compared with Embodiment 2, the pressure generated by the monitoring unit 3 is mainly applied to the slide rail 2 through the support plates 44 and the limiting rods 42, so as to reduce the load on the bidirectional telescopic cylinder 41 and help extend the service life of the bidirectional telescopic cylinder 41.

[0031] Example 4: Figure 1 , Figure 2 and Figure 5 As shown, the rest of the components are the same as in Embodiment 2, except that the drive mechanism 1 includes a base 11, a bracket 12, a reel 13, a drive motor 14, and a traction rope 15. The base 11 is fixedly mounted on the dock ground, the bracket 12 is fixedly mounted on the base 11, the reel 13 is rotatably mounted on the bracket 12, the drive motor 14 is located on one side of the bracket 12 and is used to drive the reel 13 to rotate, one end of the traction rope 15 is connected to the reel 13, and the other end of the traction rope 15 is connected to the upper end of the back plate 32. By driving the reel 13 to rotate through the drive motor 14, the traction rope 15 is wound or released, thereby causing the monitoring unit 3 to slide up and down, adjusting the height position of the monitoring unit 3.

[0032] Furthermore, the ship berthing monitoring equipment also includes a protective cover 5 installed on top of the slide rail 2. The protective cover 5 has a perforation 51 and a first fixed pulley 52 on the side facing the drive mechanism 1. A second fixed pulley 53 is installed on the inner top surface of the protective cover 5. The other end of the traction rope 15 passes through the first fixed pulley 52, the perforation 51, and the second fixed pulley 53, and is connected to the upper end of the back plate 32. When the drive mechanism 1 drives the monitoring unit 3 to slide upwards to the top of the slide rail 2, the monitoring unit 3 enters the protective cover 5. In extreme windy and rainy weather, or when the monitoring unit 3 is not in use, it can slide upwards into the protective cover 5 to reduce the impact of the external environment on the monitoring unit 3 and protect it. The perforation 51 for threading the traction rope 15 is located on the side of the protective cover 5, which helps to reduce rainwater entering the protective cover 5.

[0033] Example 5: Figure 2 and Figure 5 As shown, the rest of the parts are the same as in Embodiment 4. The difference is that the protective cover 5 is provided with a symmetrically distributed clearance groove 54 on the side. The clearance groove 54 corresponds to the uppermost limiting hole 22. The limiting rod 42 passes through the uppermost limiting hole 22 and extends into the clearance groove 54. The design of the clearance groove 54 can prevent the limiting rod 42 from hitting the protective cover 5 and causing damage.

[0034] In this embodiment, a transparent observation window 55 is provided on the side of the protective cover 5. Even if the laser rangefinder 33 is located inside the protective cover 5, the berthed ship can still be monitored through the observation window 55, which has good applicability.

[0035] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
