A handrail 31 is installed on the ladder 30 along its extension direction.

[0028] Reference Figures 1-3The freight mechanism 4 is vertically arranged on one side of the frame 1 for vertical transportation of accessories or tools. The freight mechanism 4 includes a vertically arranged freight track 40, which includes four rectangular guide rails 400. In this embodiment, the guide rails 400 are channel steel. A top plate 401 is fixed to the top of the four guide rails 400. A horizontally arranged connecting rod 402 is fixed between the guide rails 400 and between the guide rails 400 and the platform plate 10.

[0029] Reference Figures 1-4 A storage box 41 is installed between four guide rails 400. The storage box 41 has a cuboid structure. A winch 42 is installed on the top surface of the top plate 401. The pull rope of the winch 42 is connected to the top of the storage box 41, so that the storage box 41 is driven to move up and down by the winch 42. Four pulley groups 43 are respectively set on opposite sides of the storage box 41. The upper and lower pulley groups 43 on the same side are symmetrically arranged. The pulley group 43 includes an ear plate 430 fixed to the side wall of the storage box 41. A support rod 431 is hinged to the ear plate 430. A pulley 432 is rotatably connected to the end of the support rod 431. The pulley 432 is rolled and supported in the guide rail 400. The support rod 431 is inclined and a spring 433 is installed between the end of the support rod 431 and the side wall of the storage box 41.

[0030] Reference Figures 2-5 The limiting mechanism 5 includes a mounting box 50, which is fixed to the bottom of the storage box 41. Inside the mounting box 50, a card plate 51 is slidably installed at the position corresponding to the four guide rails 400. The card plate 51 is U-shaped. A clearance hole 500 is opened on the side wall of the mounting box 50 at the position corresponding to the card plate 51. The mounting box 50 is also provided with a driving component 52 for driving the card plate 51 through the clearance hole 500. Two baffles 53 are symmetrically fixed to the outer wall of each guide rail 400. The card plate 51 is movably locked on the guide rail 400 and rests on the top surface of the baffle 53.

[0031] Reference Figure 3 and Figure 5 The drive assembly 52 includes two drive gears 520 rotatably mounted inside the mounting box 50. Each drive gear 520 has a driven gear 521 coaxially fixed to its surface. A drive rack 522 is slidably mounted inside the mounting box 50. The drive rack 522 meshes with the two drive gears 520. The moving direction of the drive rack 522 is perpendicular to the moving direction of the clamping plate 51. A clearance hole 501 is provided on the side wall of the mounting box 50 at the position corresponding to the drive rack 522. A guide strip 523 is fixed to the surface of the drive rack 522 along the moving direction. The guide strip 523 cooperates with the guide groove on the inner wall of the mounting box 50 to achieve the stability of the moving trajectory of the drive rack 522.

[0032] Reference Figure 5Each card plate 51 has a driven rack 524 fixedly attached to it. The driven rack 524 is perpendicular to the driving rack 522. The driven rack 524 meshes with the driven gear 521. The two driven racks 524 meshing with the same driven gear 521 are arranged in a centrally symmetrical manner. A guide bar 525 is fixedly attached to the surface of the driven rack 524 along the moving direction. The guide bar 525 cooperates with the guide groove on the inner wall of the mounting box 50 to achieve the stability of the moving trajectory of the driven rack 524.

[0033] The implementation principle of the maintenance support for port equipment maintenance in this embodiment of the utility model is as follows: the maintenance support is moved to the equipment that needs to be repaired by the walking mechanism 2. According to the location of the equipment that needs to be repaired, the staff walks to the corresponding platform plate 10 by climbing ladder 30. The handrail 31 and the platform railing 12 play a role in safety protection.

[0034] The storage box 41 is transported to the bottom of the freight track 40 by the winch 42, and another worker puts the accessories or tools into the storage box 41. Then, the winch 42 is controlled to lift the storage box 41 to the corresponding platform plate 10 so that the workers on the platform plate 10 can take it out and use it.

[0035] After maintenance is completed, to prevent the winch 42's rope from remaining taut for an extended period, the winch 42 is controlled to rewind the rope, raising the storage box 41 to the top of the freight track 40. Subsequently, the operator pulls the drive rack 522 outward, causing the drive gear 520 to rotate. The drive gear 520 then rotates the driven gear 521, which in turn moves the driven rack 524. The driven rack 524 then moves the clamping plate 51 through the clearance hole 500 out of the mounting box 50 and onto the top surface of the baffle 53. The baffle 53 provides vertical support to the mounting box 50, thereby reducing the stress on the rope.

[0036] This maintenance support is adaptable to different heights of the equipment to be repaired. It can be easily moved to the location of the equipment to be repaired. As needed, the staff can climb onto the platform 10 at different heights and transport the required accessories or tools to the corresponding platform 10 through the freight mechanism 4 for the staff to use. This effectively solves the problems of inconvenience in high-altitude operations and poor adaptability to working conditions.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
