[0001] This utility model relates to the field of ship charging technology, specifically to a ship shore-based charging lifting platform. Background Technology
[0002] Electric vessels are gradually being adopted in inland waterway transportation and other fields due to their numerous advantages. However, inland waterways often traverse mountainous or complex terrain areas, with sparsely distributed and widely spaced wharves along the banks. The rugged terrain on both sides of the waterway makes the site selection of traditional charging stations limited, the laying of power transmission lines difficult, and power transmission and charging extremely inconvenient. Against this backdrop, one applicant has designed a charging station to be located on the bank, with the charging connection equipment installed on a lifting platform that can be raised and lowered along the bank, in order to accommodate both the site selection of charging facilities and the connection of target vessels.
[0003] The charging platform needs to accommodate and support the charging facilities, and it is also liftable, which makes it inconvenient for operators to inspect and maintain the charging facilities. In addition, the operation is also more difficult when connecting charging cables due to the space and location of the platform, which affects charging efficiency and safety. Utility Model Content
[0004] In view of the shortcomings of existing technologies, this utility model proposes a ship shore-based charging lifting platform to solve the technical problem of inconvenience for operators to enter the lifting platform for maintenance or to connect charging cables.

The side of the lifting frame extends beyond the bearing frame, and the extended part is provided with a guide structure and a traction structure. The top of the bearing frame is surrounded by a fence, and the bearing frame is used to support the charging equipment.
[0006] Optionally, the guide structure is provided on both sides of the lifting frame, and at least one set is provided on each side. The guide structure includes two side guides fixed to the front and rear sides of the lifting frame and an end guide fixed to the outer end side of the lifting frame.
[0007] Optionally, the traction structure is located on the top of the lifting frame, and at least one set is provided, wherein the traction structure is a pulley.
[0008] Optionally, a buffer block is provided at the bottom of the lifting frame.
[0009] Optionally, the system also includes a walking ladder, with connecting rods on both sides of one end of the walking ladder. A limiting sliding structure is provided inside the bearing frame, and the connecting rods of the walking ladder are movably disposed in the limiting sliding structure. A limiting structure for supporting the walking ladder is also provided at the bottom of the limiting sliding structure.
[0010] Optionally, the connecting rod has a circular cross-section, and the walking ladder can rotate around the axis of the connecting rod after it slides out.
[0011] Optionally, the fence is provided with a first gap area facing the direction in which the walking ladder slides out.
[0012] Optionally, the charging device is fixedly installed in the area above the lifting frame and located on the side close to the guide structure and traction structure, and the fence is provided with a second gap area on this side.
[0013] Optionally, the limiting sliding structure within the load-bearing frame includes two parallel profiles welded to the frame body at a distance, the connecting rod is located in the spacing area between the two profiles, and the limiting structure is disposed on the lower side of the spacing area.
[0014] Optionally, the side guides and / or end guides can be interchangeably connected to the lifting frame.

Detailed Implementation
[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0031] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0032] To address the technical challenges of limited range and low operational efficiency of electric vessels due to the lack of coastal charging infrastructure, the applicant has developed a shore-based charging lifting device for vessels. (See also...) Figure 11 and Figure 12 The device includes a lifting power source 91, a cable reel 92, a lifting guide rail 90, and a lifting platform. The lifting guide rail 90 is vertically fixed to the shore wall, and the lifting platform is slidably connected to the lifting guide rail 90. The lifting power source 91 and the cable reel 92 are located at the top of the shore wall. The lifting power source 91 is connected to the lifting platform via a cable and controls its lifting height. The cable reel 92 is driven by the power source and can release or wind cables according to changes in the height of the lifting platform. To improve the stability of the device's operation, the applicant has also developed a shore-based charging lifting platform for this vessel.
[0033] Please see the appendix Figure 1One possible implementation of the lifting platform is as follows: Including the lifting frame 1 connected as one unit ( Figure 9 ) and load-bearing frame 2 ( Figure 7 After the lifting frame 1 is inserted into the load-bearing frame 2, they are connected as one unit by welding or other methods. The side of the lifting frame 1 extends beyond the load-bearing frame 2. (See reference...) Figure 11 The lifting frame 1 is not fully inserted into the load-bearing frame 2, but a portion is left on the outside, and the extended portion (the reserved portion) is equipped with a guide structure 11 and a traction structure 12. The top of the load-bearing frame 2 is surrounded by a fence 21, and a charging device 22 is installed inside the load-bearing frame 2. Figure 3 The charging device 22 has a cable interface 220 on its top for connecting the cable reel 92, and a charging interface 221 on its panel for connecting the ship's charging cable. The lifting frame 1 is integrated with the supporting frame 2. The lifting frame 1 extends beyond the supporting frame 2 and is equipped with a guide structure 11 and a traction structure 12. The guide structure 11 ensures stable sliding of the lifting platform along the lifting guide rail 90, and the traction structure 12, in conjunction with the lifting power source 91, stably controls the lifting height of the lifting platform, greatly improving the stability of the device's operation. The railing 21 around the top of the supporting frame 2 provides reliable safety protection for operators, ensuring their personal safety during maintenance or connection of charging cables. The charging device 22 installed inside the supporting frame 2 can meet the charging needs of electric ships.
[0034] In one possible implementation, see Appendix Figure 9 and Figure 10 The guide structure 11 is located on both sides of the lifting frame 1, with at least one set on each side. The guide structure 11 includes two side guide bodies 111 fixed to the front and rear sides of the lifting frame 1 and an end guide body 112 fixed to the outer end of the lifting frame 1, which cooperate with the concave cavity limiting guide structure of the two steel rails. In the above embodiment, the multi-directional guide design can guide the lifting platform to slide accurately and smoothly along the lifting guide rail 90 in all directions, effectively avoiding shaking and deviation during the lifting process, and greatly improving the stability of the device operation.
[0035] In one possible implementation, see Appendix Figure 10The traction structure 12 is located on top of the lifting frame 1, and at least one set is provided. The traction structure 12 is a pulley 121. A suspension is installed at the top of the bank, with one end fixed to the bank foundation (this end is also held down by a cable reel) and the other end extending out of the bank. A pulley is provided at the outer end of the suspension. Two pulleys 121 are provided on the lifting platform. After the cable is led out from the lifting power source, it passes sequentially through the upper pulley on the suspension, the two pulleys 121 on the lifting platform, and finally connects to the suspension. The two pulleys 121 on the lifting platform form a movable pulley. The upper pulley on the suspension provides a stable steering support point for the cable, ensuring the stability of the cable's running path. Based on the labor-saving principle of the movable pulley, the pulling force required by the lifting power source is reduced, alleviating the power burden and making the lifting operation of the lifting platform 5 easier and more efficient, thus improving the economy and reliability of the entire device.
[0036] In one possible implementation, see Appendix Figure 9 The bottom of the lifting frame 1 is provided with a buffer block 113. In the above embodiment, in the lower end area of the rails, a limiting component is provided in the concave structure of the two rails to restrict the continued sliding of the lifting platform. The buffer block 113 is provided at the bottom of the lifting frame 1. When the lifting platform descends along the rails to the bottom, and the limiting component restricts its continued sliding, the buffer block 113 can play a buffering and shock-absorbing role, effectively absorbing the impact force of the platform's descent, avoiding a hard collision between the platform and the bottom, reducing equipment wear and noise, and ensuring the safety and stability of the platform and internal charging equipment. The optional materials include rubber, polyurethane, and other materials with good elasticity and cushioning performance.
[0037] In one possible implementation, see Appendix Figures 4-8 The system also includes a walking ladder 3, with connecting rods 31 on both sides of one end. A limiting sliding structure 13 is provided within the supporting frame 2. The connecting rods 31 of the walking ladder 3 are movably mounted on the limiting sliding structure 13. A limiting structure 14 for supporting the walking ladder 3 is also provided at the bottom of the limiting sliding structure 13. The connecting rods 31 on both sides of one end of the walking ladder 3 are movably mounted on the limiting sliding structure 13 within the supporting frame 2, allowing the walking ladder 3 to flexibly slide and adjust its position relative to the supporting frame 2. This facilitates workers moving the walking ladder 3 to a suitable position to enter and exit the lifting platform according to actual needs. For example, after the platform is lowered to the same height as the boat, the walking ladder 3 can be placed on the boat, making it convenient for workers to enter the platform to connect charging cables. The limiting structure 14 at the bottom of the limiting sliding structure 13 ensures that one end of the walking ladder 3 will not fall when it is not slid out, i.e., retracted into the supporting frame 2, preventing excessive sliding or shaking of the walking ladder 3 and providing stable and reliable passage for workers, further enhancing the safety and practicality of the entire device.
[0038] In one possible implementation, see Appendix Figure 8The connecting rod 31 has a circular cross-section, allowing the walking ladder 3 to rotate around its axis after sliding out. The fence 21 has a first notch 211 facing the direction the walking ladder 3 slides out, allowing workers to access the platform from the ship to connect charging cables after the platform descends to the same height as the ship. In one possible implementation, see Appendix. Figure 11 The charging device 22 is fixedly installed above the lifting frame 1, near the guide structure 11 and the traction structure 12. A second notch 212 is provided on this side of the fence 21, allowing personnel to access the platform from the shore for maintenance and other operations when the platform rises to the top of the shore foundation. On one hand, the guide structure 11 and traction structure 12 provide stable support and guidance for the platform's lifting. The close proximity of the charging device 22 allows the torque generated by the equipment's gravity to be better transmitted through the lifting frame 1 to the guide and traction components. Their relatively stable structural characteristics ensure smooth force transmission and reduce uneven force distribution and swaying of the platform due to the equipment's weight. On the other hand, the second notch 212 on the corresponding side of the fence 21 allows personnel to easily access the platform for maintenance when it rises to the top of the shore foundation, balancing the rationality of the equipment layout with the convenience of personnel operation.
[0039] In one possible implementation, see Appendix Figure 7 The limiting sliding structure 13 within the load-bearing frame 2 includes two parallel profiles 131 welded to the frame body at a distance, a connecting rod 31 located in the spacing area between the two profiles 131, and a limiting structure 14 located on the lower side of the spacing area.
[0040] In one possible implementation, the side guide 111 and / or end guide 112 can be interchangeably connected to the lifting frame 1, for example, by providing countersunk holes and connecting with anti-loosening screws. Common materials for the side guide 111 and / or end guide 112 include oil-impregnated nylon, which has good self-lubricating properties, reduces the coefficient of friction, and minimizes wear; polyoxymethylene (POM) is also a good choice, with high hardness, good rigidity, and excellent wear resistance and fatigue resistance; and MC nylon, which has high strength and good toughness, is not easily damaged under pressure and friction, effectively ensuring the stable operation of the guide structure for a long time and extending the service life of the equipment.
