Abstract
Description
Technical Field
[0001] This invention relates to the field of ro-ro facilities technology at wharves, and specifically to a slope-adjustable lifting platform and system. Background Technology
[0002] Currently, when vehicles are rolled onto ships from the dock or unloaded ashore by ships, the ro-ro ramps on the ships are typically used to create a vehicle loading / unloading channel on the dock. However, because the height difference between the dock surface and the water level at the front edge varies with the tide, ro-ro ships need to wait for a suitable tide level when carrying out ro-ro loading and unloading. Especially in ports with large water level fluctuations, the long waiting time for ro-ro ships and the low loading and unloading efficiency undoubtedly cause huge economic losses.
[0003] When using an adjustable-slope unloading channel, it is difficult to precisely adjust the slope and channel length, which has significant limitations when dealing with different beach heights and different span lengths. Summary of the Invention

Detailed Implementation
[0040] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways, which may be limited to or covered by the present invention.
[0041] Example 1:
[0042] See Figures 1 to 5 An adjustable-slope lifting platform, or simply a lifting platform, is used for transportation between two banks. The adjustable-slope lifting platform includes a lifting support module, a passage platform module, and a docking ramp 3. The lifting support module includes at least one lifting support component 1 arranged along the width of the passage platform module. The lifting support component 1 includes a support body 1.1, a movable block 1.2, and a drive assembly 1.3. The support body 1.1 is vertically positioned between the two banks, and the movable block 1.2 is movably connected to the support body 1.1. The drive assembly 1.3 is mounted on the support body 1.1, and its output end is connected to the movable block 1.2. The drive assembly 1.3 drives the movable block 1.2 to move up and down along the support body 1.1. The passage platform module includes at least two mutually hinged platform segments 2, which are supported by the lifting support module. Both platform segments 2 are equipped with docking ramps 3 for connecting with the two banks. The lifting body passes through the platform segments 2, and the movable block 1.2 is hinged to the bottom of the platform segments 2.
[0043] In this embodiment, see reference Figure 10 The passage platform module is set in the water between the two banks via a lifting support module. The docking ramp 3 is installed on the platform section 2 by a hinge. Driven by external force, the docking ramp 3 is flipped outward from the platform section 2 and then connected to the opposite bank, thus forming a passage for transportation between the two banks. In addition, the driving component 1.3 of each lifting support unit 1 in the lifting support module drives the movable block 1.2 to move up and down along the support body 1.1. The movable block 1.2 can drive the corresponding platform section 2 to rise or fall, so that the lifting height and slope of each platform section 2 can be freely adjusted so that it can connect to the two banks at different heights when the water level difference is the largest. This meets the landing needs of landing ships with different ship heights during high tide or low tide, or the docking of the offshore platform with the coast.
[0044] Based on the above embodiments, see Figure 9The supporting body 1.1 includes a top seat 1.1.1, a base 1.1.2, and two guide posts 1.1.3 connected between the top seat 1.1.1 and the base 1.1.2. The base 1.1.2 is located at the bottom of the water area, and the two guide posts 1.1.3 are spaced apart. The driving assembly 1.3 includes a driving component 1.3.1 and a transmission screw 1.3.2. The driving component 1.3.1 is located on the top seat 1.1.1. One end of the transmission screw 1.3.2 passes through the movable block 1.2 and is rotatably connected to the base 1.1.2. The other end of the transmission screw 1.3.2 passes through the top seat 1.1.1 and is connected to the output shaft of the driving component 1.3.1. The transmission screw 1.3.2 is threadedly connected to the movable block 1.2. The driving component 1.3.1 drives the transmission screw 1.3.2 to rotate, thereby causing the movable block 1.2 to move up and down along the transmission screw 1.3.2. At the same time, it drives the platform segment 2 to rise and fall, or one end to rise and the other end to fall, thus realizing the adjustment of the height and slope of the entire lifting platform. The driving component 1.3.1 is set on the top seat 1.1.1 and is also located at the highest point of the lifting platform, which can easily achieve water isolation and facilitate maintenance.
[0045] The movable block 1.2 has guide holes 1.2.1 at both ends for the guide post 1.1.3 to pass through. The movable block 1.2 is provided with a nut seat 1.2.2 that matches the transmission screw 1.3.2. The transmission screw 1.3.2 is threadedly connected to the movable block 1.2 through the nut seat 1.2.2. The driving component 1.3.1 drives the transmission screw 1.3.2 to rotate, so that the transmission screw 1.3.2 drives the movable block 1.2 to move along the guide post 1.1.3 through the nut seat 1.2.2. The lifting support unit 1 also includes multiple guide wheels 1.4. Multiple guide wheels 1.4 are evenly arranged on the edge of the guide hole 1.2.1. The guide wheels 1.4 are in rolling contact with the guide post 1.1.3. There is a self-locking mechanism between the transmission screw 1.3.2 and the threaded seat. Through this transmission mechanism, the lifting platform can be self-locked at any position. The rotation of the transmission screw 1.3.2 drives the movable block 1.2 to move up and down along the guide post 1.1.3 via the nut seat 1.2.2. The two ends of the movable block 1.2 are respectively sleeved on the two guide posts 1.1.3 through the guide holes 1.2.1, and roll in contact with the guide posts 1.1.3 through the guide wheel 1.4, thereby reducing the friction between the movable block 1.2 and the guide posts 1.1.3.
[0046] Furthermore, platform segment 2 includes a truss body 2.1 and a passage panel 2.2. The truss body 2.1 contains a hinged fixing frame 2.3 corresponding to the lifting support unit 1. The hinged fixing frame 2.3 is hinged to the movable block 1.2 via a first pin 2.4. The passage panel 2.2 is mounted on the truss body 2.1. When the lifting support module corresponding to each platform segment 2 drives the platform segment 2 to rise or fall, the truss body 2.1 can rotate around the pin, thereby changing the slope of the platform segment 2. The truss body 2.1 is composed of multiple rows of truss unit components. Different numbers of trusses can be selected to form the truss body 2.1 according to the load level, meeting different passage load requirements.
[0047] Specifically, the lifting support module includes two lifting support components 1, which are spaced apart along the width direction of the platform segment 2. The two lifting support components 1 respectively support both sides of the platform segment 2 in the width direction to improve the structural stability of the overall lifting platform.
[0048] Preferably, the passage platform module includes multiple platform segments 2, which are sequentially hinged along the length direction. Two platform segments 2 at each end are supported by two lifting support modules, which are spaced apart along the length direction of the platform segment 2. The slope-adjustable lifting platform also includes a hinged sliding mechanism 4, with adjacent platform segments 2 hinged together by the hinged sliding mechanism 4. The number of platform segments 2 is determined according to the distance required for passage between the two banks to meet the needs of different passage lengths. The hinged connection of adjacent platform segments 2 by the hinged sliding structure avoids interference between adjacent platform segments 2 and allows for rotation between platform segments 2 to adjust the slope, thus enabling docking at banks of different heights and accommodating landing vessels with different hull heights during high or low tide, or docking of the offshore platform with the coast.
[0049] Among them, see Figures 6 to 8 The hinged sliding mechanism 4 includes a second pin 4.1 and hinge joints 4.2 and sliding seats 4.3 respectively located at both ends of the platform segment 2. The hinge joint 4.2 is hinged to the sliding seat 4.3 of the adjacent platform segment 2 through the second pin 4.1; the two ends of the second pin 4.1 are slidably disposed on the sliding seat 4.3 along the length direction of the platform segment 2. The hinged sliding structure can realize the hinge between two adjacent platform segments 2, and also ensure that each platform segment 2 has a certain degree of freedom when connected.
[0050] In addition, the drive assembly 1.3 also includes a reducer 1.3.3. The drive component 1.3.1 is connected to the transmission lead screw 1.3.2 via the reducer 1.3.3. There are two drive assemblies 1.3, which are spaced apart between the two guide columns 1.1.3. The reducer 1.3.3 has a built-in brake. After the lifting position is reached, the drive motor is de-energized, and the reducer 1.3.3 can lock the transmission lead screw 1.3.2. At the same time, there is a self-locking relationship between the transmission lead screw 1.3.2 and the nut seat 1.2.2, which further ensures the self-locking stability of the platform segment 2 at any position and effectively guarantees structural safety. The two drive assemblies 1.3 synchronously drive the movable block 1.2 to move along the guide column 1.1.3, improving transmission efficiency and ensuring transmission stability.
[0051] Example 2:
[0052] The difference from Embodiment 1 is that the hinged sliding mechanism 4 includes circular slide rails and sliders located at both ends of the platform segment 2, with the sliders slidably positioned within the circular slide rails of adjacent platform segments 2. As the platform segment 2 rotates, it drives the sliders to move within the circular slide rails, thus ensuring the degree of freedom of connection between the platform segments 2.
[0053] Example 3:
[0054] The difference from Example 1 is that the lifting support unit 1 adopts a hoisting wire rope lifting method.
[0055] Example 4:
[0056] The difference from Embodiment 1 is that the lifting support unit 1 uses a hydraulic pin for lifting.
[0057] Example 5:
[0058] The difference from Embodiment 1 is that the docking ramp 3 is connected to the two end platform segments 2 through a translation mechanism. The translation mechanism drives the docking ramp 3 to move so that the docking ramp 3 on the two end platform segments 2 docks with the two banks respectively.
[0059] Example 6:
[0060] This embodiment provides a slope-adjustable lifting platform system, which includes a water level gauge, a control console, and the slope-adjustable lifting platform as described above. The water level gauge is used to measure the water level, and the control console is electrically connected to the water level gauge and each drive component 1.3.
[0061] The initial state of the slope-adjustable lifting platform is as follows: Figure 11 As shown, when connecting the two banks and ascending to higher ground, see... Figure 12Each platform segment 2 has the same lifting height for its corresponding lifting support piece 1. The control console controls each drive component 1.3 to synchronously drive the corresponding movable block 1.2 to lift until the platform segment 2 is at the same height as the banks.
[0062] When the two sides of the strait are not at the same level, see Figures 13 to 16 First, the water level is automatically calculated using a water level gauge to determine the lifting height of the two end platform segments 2. Then, the lifting height of the corresponding lifting support piece 1 of each intermediate platform segment 2 is determined by the inclination angle between them. The control console drives the drive component 1.3 to lift the movable block 1.2. During the lifting process, the lifting height of the movable block 1.2 of the corresponding lifting support piece 1 of each intermediate platform segment 2 changes linearly with the installation position. Through the hinge between the movable block 1.2 of the lifting support piece 1 and each intermediate platform segment 2, and the hinge sliding mechanism 4 between the platform segments 2, the predetermined angle is automatically adjusted to form a platform with a certain slope. After the platform is lifted into place, it self-locks when the power is cut off, and the two horizontal end ramps flip over, thereby achieving the connection of the two banks with unequal heights.
[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
