Description

Technical Field

[0001] This utility model relates to the field of trestle technology, and in particular to a dock trestle device. Background Technology

[0002] In shallow-water docks, barge loading typically involves the barge carrying two independent steel structural members. Excavators are used to construct a temporary connecting passage between the dock and the ship's hold. This technology is suitable for small docks with limited infrastructure and is relatively low-cost. However, this existing technology has the following drawbacks:

[0003] Disadvantage 1:

[0004] Because the connection channels are not fixed, excavators are frequently needed to correct the steel structure, and each correction takes 1-2 hours, which seriously affects the loading efficiency of the barge.

[0005] Cause: Due to the influence of sea waves and tides, the barge will shift, causing the connecting channel to shift as well.

[0006] Disadvantage 2:

[0007] During high and low tides, the connecting passageway will form a certain slope, which may cause dump trucks to slip or deviate when passing through, posing a significant safety hazard.

[0008] Cause: The two independent steel structure components are too narrow, and there are no safety guards at the edges of the components.

[0009] Therefore, it is necessary to develop a dock pier device to solve the above problems. Utility Model Content

[0010] The purpose of this invention is to design a dock trestle device to solve the above-mentioned problems.

[0011] This utility model achieves the above objectives through the following technical solutions:

[0012] A dock pier assembly, comprising:

[0013] Base; the lower end of the base is fixed in place;

[0014] First hinge;

[0015] Large springboard; the first end of the base is hinged to the first end of the large springboard via a first hinge;

[0016] Second hinge;

[0017] Small springboard; the second end of the large springboard is hinged to the first end of the small springboard via a second hinge;

[0018] Two upright posts; the two upright posts are installed on both sides above the second end of the large scaffolding, and the two upright posts are parallel to each other;

[0019] Two sets of tensioning structures are arranged side by side; the tensioning structure includes a winch, a wire rope, a first pulley assembly, a second pulley assembly, and a third pulley assembly. The winch is installed at the second end of the base, the first pulley assembly is installed on the base and is located near the first end of the base, the second pulley assembly is installed on the top of the column, and the third pulley assembly is installed on the large scaffolding and is located near the second end of the large scaffolding. The first end of the wire rope is connected to the drum of the winch, and the second end of the wire rope passes around the bottom of the first pulley assembly and the top of the second pulley assembly in sequence before connecting to the third pulley assembly.

[0020] A laser signal transmitting and receiving module is used to detect the mooring position of barges; the laser signal transmitting and receiving module is mounted on a column and oriented towards the small gangway.

[0021] The beneficial effects of this utility model are as follows:

[0022] The wharf trestle device in this application is fixed in position, and the connecting channel consisting of small trestle, large trestle, and base is fixed. When the barge is displaced by sea waves and tides, it is not necessary to use excavators to correct its course frequently, which increases the loading efficiency of the barge.

[0023] This application consists of a large gangplank, a small gangplank, and a base connected by hinges, providing mobility. During high and low tides, the connecting channel can change with the rise and fall of the barge, and can also be freely adjusted by a winch, ensuring the stability of the connecting channel and increasing the safety of barge operations.

[0024] In this application, the laser signal transmitting and receiving module generates a 3D point cloud model of the dock and barge by transmitting pulsed laser and recording the reflection time difference, so as to accurately control the barge berthing range and facilitate the connection between the automatic pier device and the barge.

[0040] like Figure 1 As shown, a dock pier device includes:

[0041] Base 3; the lower end of base 3 is fixed in a fixed position;

[0042] First hinge 11;

[0043] Large springboard 2; the first end of the base 3 is hinged to the first end of the large springboard 2 via the first hinge 11;

[0044] Second hinge 12;

[0045] Small springboard 1; The second end of the large springboard 2 is hinged to the first end of the small springboard 1 via the second hinge 12;

[0046] Two upright posts 5; the two upright posts 5 are installed on both sides above the second end of the large scaffolding 2, and the two upright posts 5 are parallel to each other;

[0047] Two sets of tensioning structures are arranged side by side; the tensioning structure includes a winch 4, a wire rope 7, a first pulley assembly 8, a second pulley assembly 9, and a third pulley assembly 10. The winch 4 is installed at the second end of the base 3. The first pulley assembly 8 is installed on the base 3 and is located near the first end of the base 3. The second pulley assembly 9 is installed on the top of the column 5. The third pulley assembly 10 is installed on the large scaffold 2 and is located near the second end of the large scaffold 2. The first end of the wire rope 7 is connected to the drum of the winch 4. The second end of the wire rope 7 passes under the first pulley assembly 8 and above the second pulley assembly 9 in sequence before connecting to the third pulley assembly 10.

[0048] A laser signal transmitting and receiving module 6 is used to detect the mooring position of the barge; the laser signal transmitting and receiving module 6 is installed on the column 5 and is set towards the small gangway 1. Figure 1The laser signal transmitting and receiving module 6 shown is not positioned high because the hull height of the ship in this embodiment is not high. Therefore, the second end of the raised gangway 2 will not block the signal transmission and reception of the laser signal transmitting and receiving module 6. In other embodiments, in order to adapt to ships with higher hulls, the position of the laser signal transmitting and receiving module 6 on the column 5 can be adjusted upward.

[0049] like Figure 3-5 As shown, both the large scaffold 2 and the small scaffold 1 include multiple crossbeams 16, multiple longitudinal trusses 17, and a panel 19. The multiple crossbeams 16 are arranged parallel to each other on the same plane, and the multiple longitudinal trusses 17 are arranged parallel to each other on the same plane. The longitudinal trusses 17 are installed above the crossbeams 16 and are perpendicular to the crossbeams 16. The panel 19 is installed on the multiple longitudinal trusses 17.

[0050] like Figure 3-5 As shown, both the large scaffold 2 and the small scaffold 1 also include multiple elbow plates 18. The connection between the crossbeam 16 and the longitudinal truss 17 is achieved by four elbow plates 18. One side of the elbow plate 18 is connected to the crossbeam 16, and the other side is connected to the longitudinal truss 17.

[0051] like Figure 4 and 7 As shown, an anti-slip net is provided on the panel 19; the anti-slip net includes multiple anti-slip strips 20, the first part of the anti-slip strips 20 is arranged along the length direction of the large springboard 2 and the small springboard 1, and the second part of the anti-slip strips 20 is arranged along the width direction of the large springboard 2 and the small springboard 1. The first part of the anti-slip strips 20 and the second part of the anti-slip strips 20 intersect perpendicularly and form a mesh structure.

[0052] like Figure 1 and 2 As shown, both the first hinge 11 and the second hinge 12 include two rotating seats 13, a rotating plate 14, and a first pin 15. The two rotating seats 13 are arranged in parallel with a gap between them. The rotating plate 14 is placed within the gap. Both the rotating seats 13 and the rotating plate 14 have through holes, through which the pin passes. In the first hinge 11, the two rotating seats 13 are connected to the base 3, and the rotating plate 14 is connected to the large springboard 2. In the second hinge 12, the two rotating seats 13 are connected to the large springboard 2, and the rotating plate 14 is connected to the small springboard 1.

[0053] like Figure 4 As shown, mounting bases 21 are provided on both sides of the large springboard 2, and the third pulley assembly 10 is mounted on the mounting bases 21.

[0054] like Figure 6As shown, the first pulley assembly 8, the second pulley assembly 9, and the third pulley assembly 10 each include four partitions 22, a second pin 23, and three pulleys 24. The four partitions 22 are arranged parallel to each other, and a pulley 24 is installed in the gap between two adjacent partitions 22. Both the pulleys 24 and the partitions 22 are provided with through holes. The second pins 23 are provided through the through holes in the pulleys 24 and the partitions 22, and the pulleys 24 and the second pins 23 are rotatably engaged. The partitions 22 are mounted on the mounting base 21 below the large scaffold 2, and the partitions 22 are mounted on the panel 19 on the base 3.

[0055] In this application, the small gangway 1 is located at the foremost end of the dock pier device, and is the part that directly contacts and moves with the hull of the vessel being carried. The small gangway 1 is connected to the large gangway 2 via a hinge. This hinged connection allows the small gangway 1 to rotate flexibly relative to the large gangway 2 within a certain range, effectively adapting to different displacement conditions of the vessel being carried, and ensuring that the dock pier device and the vessel always maintain a relatively stable connection.

[0056] In this application, the large gantry 2 is located in the middle of the dock trestle device, connecting the small gantry 1 and the base 3 and fulfilling the key movable function. For connection, the large gantry 2 is connected to both the base 3 and the small gantry 1 via hinges. This multi-hinge connection design allows the large gantry 2 to be raised and lowered vertically to cope with complex working environments. Simultaneously, the two side edges of the large gantry 2 are directly connected to the third pulley assembly 10, and are connected to the wire rope 7 through the third pulley assembly 10. This connection allows the winch 4 to accurately transmit the winding and unwinding operations of the wire rope 7 to the large gantry 2, thereby driving the large gantry 2 to complete the corresponding actions.

[0057] In this application, the base 3 is securely fixed to the wharf using concrete filling, providing a solid and reliable supporting foundation for the wharf trestle device. The connection between the base 3 and the winch 4 ensures a stable installation position for the winch 4, while also guaranteeing that the forces generated by the winch 4 during operation are effectively transmitted to the entire device structure. The connection between the base 3 and the column 5 enhances the overall vertical stability and structural strength of the device. The connection between the base 3 and the first pulley assembly 8 plays a crucial role in guiding the wire rope 7 and transmitting force. Furthermore, the base 3 is also connected to the large trestle platform 2 via hinges, providing a support point and movable base for the rotation of the large trestle platform 2.

[0058] In this application, the winch 4 is directly connected to the base 3, providing stable installation support. Simultaneously, the winch 4 is directly connected to the wire rope 7, serving as the core power component of the dock trestle device. By winding and unwinding the wire rope 7, it provides the necessary power for the raising and lowering of the large trestle platform 2. Precise control of the winch 4 ensures that the large trestle platform 2 performs its raising and lowering actions smoothly and accurately according to actual needs.

[0059] In this application, the column 5 is firmly fixed to the base 3 by concrete, and its top is directly connected to the second pulley assembly 9. The presence of the column 5 not only provides a stable installation height for the pulley 24, but also further enhances the vertical support and structural stability of the entire device structure.

[0060] In this application, the laser signal transmitting and receiving module 6 is fixed in front of the column 5. The module transmits and receives pulsed laser light, records the reflection time difference to generate a 3D point cloud model of the dock and barge, and monitors the barge's berthing speed and angle in real time. If the speed exceeds the limit, an audible and visual warning is triggered. This accurately controls the barge's berthing distance to meet the working range of the dock pier device, improves the early warning capability of the dock pier device, and increases its safety.

[0061] The working principle of this application is as follows: During operation, the winch 4 operates, pulling the second end of the large gangway 2 and the small gangway 1 to a high position via the steel wire rope 7. The first pulley assembly 8 and the second pulley assembly 9 both play a role in reversing the force. Then, the ship begins to moor. The laser signal transmitting and receiving module 6 detects whether the ship is moored in place. After it is in place, the winch 4 operates to release the steel wire rope 7. The second end of the large gangway 2 and the small gangway 1 descend under their own weight until the second end of the small gangway 1 rests on the side chord of the ship, ensuring that the angles of the large gangway 2 and the small gangway 1 are consistent. The small gangway 1 is connected to the large gangway 2 via a hinge. The movement of the large gangway 2 is transmitted to the small gangway 1 through the hinge, allowing the small gangway 1 to move with the movement of the large gangway 2. At the same time, the small gangway 1 can also change with the displacement of the ship it is carrying to adapt to different working scenarios.

[0062] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
