DETAILED DESCRIPTION

[0035] In order to better understand the present invention, the content of the present invention is further described below in conjunction with the accompanying drawings and examples.

[0036] like Figure 1-2 As shown, a multifunctional platform gangway comprises: a base 1, a supporting platform 2, an access platform 3 and an escalator 4 sequentially mounted on the base 1;

[0037] The base 1 is a support frame composed of multiple rigid structures and having a grooved slide rail 11, and multiple locking bolts 12 are arranged in the slide rail 11;

[0038] The supporting platform 2 , the access platform 3 and the escalator 4 are respectively installed on the slide rails 11 of the base 1 through sliding mechanisms, and the sliding mechanisms move and are fixed along the slide rails 11 of the base 1 .

[0039] The supporting platform 2 , the access platform 3 and the gangway base 1 adopt a unified sliding mechanism, which can slide on the slide rail 11 of the base 1 through the pulley 5 , and can also be fixed by the locking bolt 12 provided on the slide rail 11 .

[0040] Since the supporting platform 2, the access platform 3 and the escalator 4 are all mounted on the truss of the base 1 through the pulley 5, and the pulley 5 can be moved and fixed along the slide rail 11 of the base 1, the position of each part can be adjusted according to actual needs. This flexibility enables the gangway to adapt to ship sides and engine rooms of different heights and angles, etc., and improves its scope of application and practicality.

[0041] The base 1 is a support frame composed of multiple rigid structures with grooved slide rails 11. This structural design can provide good support and stability to ensure the safety and reliability of the gangway during use. At the same time, the rigid structure of the base 1 also helps to improve the load-bearing capacity of the gangway, so that it can withstand a large weight of people and goods and meet the needs of different usage scenarios.

[0042] like Figure 3 As shown, the support platform 2 includes: a support frame composed of support columns 21, the upper end of the support frame is connected to the first table top 22, pulleys 5 are provided on both sides of the lower end of the support frame, a guardrail 23 is provided around the inner periphery of the first table top 22, and a hatch 24 is provided on one side of the guardrail 23.

[0043] The support frame is tightly connected to the first table top 22, making the entire platform compact and having high space utilization. The limited space can be effectively utilized to provide more activity space and working space for personnel, while also reducing the platform's occupancy and interference with the surrounding environment.

[0044] The first table 22 adopts a 16-grid truss structure. The bottom of the truss is connected to a hinge and a worm gear mechanism. A stainless steel plate is laid on the truss to form a table. The table is marked with scale dimensions, with a scale of 50 mm each, to facilitate test personnel to confirm the position and distance.

[0045] The support column 21 is designed to bear a load of 600kg and adopts a five-column and four-leg structure. The support column 21 is made of 316L square tube stainless steel. Two circles of ring beams are used in the lower middle part and the bottom to enhance the stability of the structure and provide support for the inclination adjustment mechanism.

[0046] The support frame composed of the support columns 21 provides a solid structural foundation for the platform, ensures the stability of the platform, can effectively disperse and bear the weight on the platform, and prevents the platform from tilting or being damaged due to overloading or uneven force, thereby improving the safety and reliability of the platform.

[0047] A guardrail 23 is provided around the inner periphery of the first platform 22, which can effectively prevent people from accidentally falling when walking on the platform, thereby improving the safety of the platform. The design of the guardrail 23 can also play a certain guiding and warning role, reminding people to pay attention to safety and avoid approaching the edge of the platform. In addition, a hatch 24 is provided on one side of the guardrail 23 to facilitate people to enter and exit the platform 3, while also providing good sealing and protection for the platform to prevent unauthorized people from entering or items from being lost.

[0048] like Figure 7 and Figure 8 As shown, at least one support column 21 is provided with at least one adjustment handle 211 whose length can be adjusted. By adjusting the handle 211, the length of the support column 21 can be easily adjusted, thereby changing the height of the support platform 2. The height adjustment function enables the platform to adapt to ship sides or docks of different heights and meet the needs of different usage scenarios; since the height of the support column 21 can be adjusted, the platform can better adapt to various complex environments and conditions; the design of the adjustment handle 211 makes the length adjustment process of the support column 21 simple and quick. The operator only needs to rotate or move the adjustment handle 211 to easily adjust the height of the support column 21 without the need for complex tools or equipment. This simple operation method improves work efficiency, reduces the time and labor intensity of manual adjustment, and also reduces the difficulty of operation and the possibility of errors.

[0049] The posture adjustment mechanism is a combination of a worm gear and a hinge. The pitch angle is adjusted by rotating the adjustment handle 211 so that one side of the support platform 2 is raised and lowered while the other side is fixed. The adjustment range is designed to be ±10° and the adjustment step is 1°. The angle control is achieved through the color scale on the scale. The lower edge of the color scale is flush with the support cross arm, corresponding to a calibrated inclination value.

[0050] A stainless steel mesh guardrail 23 is arranged around the supporting platform 2. The guardrail 23 has a height of 1000 mm and is laterally designed with extended legs to prevent overturning.

[0051] like Figure 4As shown, the hatch 24 includes a door body 242, a door frame 243, and a threshold 241 arranged from the lower end of the door frame 243 to the lower end of the first table 22. A quick-install and quick-release interface connected to the door body 242 is provided on the side of the door frame 243. A plurality of holes 245 are provided on the outer side of the door body 242. A quick-install and quick-release interface connected to the door body 242 is reserved on the side of the door frame 243. Two rows and two columns of screw holes are reserved on the door to facilitate the fixing of the door handle 244. The length of the gripping part of the handle 244 is 250 mm, and the distance between the lower surface of the handle 244 and the door surface is 40 mm. A plurality of holes 245 such as gourd holes are reserved on the door, and the installation position of the handle 244 on the door can be adjusted without screwing the screws. The installation position can be adjusted to the 1 / 4 area of ​​the hatch 24. The handle 244 is provided with a spiral locking mechanism to facilitate fastening and disassembly adjustment. A ruler is provided on both sides of the hatch 24 to facilitate recording the installation position. The threshold 241 (the height from the bottom edge of the door to the support platform 2) is provided with a height adjustment slide groove, with limits at both ends and scales on the edge, so that the height of the threshold 241 from the bottom edge of the door to the support platform 2 can be adjusted. The adjustment range covers 10 to 70 mm, the adjustment method is stepless adjustment, and the adjustment step is less than 5 mm.

[0052] like Figure 5 As shown, the entry and exit platform 3 includes: a lifting device 33, a second table top 31 is provided at the upper end of the lifting device 33, pulleys 5 are provided on both sides of the lower end of the lifting device 33, the lifting device 33 is provided with at least one adjustment handle 211, and handrails 32 are provided on the opposite sides of the second table top 31 and the hatch 24 at right angles.

[0053] The table size (length × width) is 1200mm × 800mm. A truss is used as the load-bearing beam. The truss is assembled by laying 3 stainless steel patterned unit plates. The stainless steel patterned plates adopt a perforated weight-reducing and drainage design.

[0054] The support structure is designed to bear a load of 500kg. It adopts a four-column and four-leg structure. The upper part of the support structure is a frame, and the lower part is a shear lifting mechanism. It is designed with extended auxiliary legs and has an anti-overturning function. The adjustment mechanism is a combination of a worm gear, a hinge, and a shear lifting platform to achieve freedom adjustment of the pitch angle and height. The pitch angle is adjusted by rotating the adjustment handles 211 on the left and right sides. The pitch angle is adjusted by lifting one side and fixing the other side. The design adjustment range is ±30°, the adjustment step is 3°, and the angle control is achieved through the color code on the scale. The entry and exit platform 3 uses a shear lifter for height adjustment, and the height adjustment is achieved by rotating the rotating handle on one side. Clockwise rotation is for descent, and counterclockwise rotation is for ascent. When adjusting the platform height, first place the platform surface at a horizontal angle, and then rotate the handle to the appropriate height.

[0055] There are handrail 32 quick-install interfaces on both sides of the access platform 3. The handrail 32 adopts a segmented design, each section is about 200mm long, and the handrail 32 is inserted into the quick interface by plugging, and the positioning pin is locked to achieve fixation. The length of the handrail 32 covers the uppermost end to the lowermost end of the access platform 3. When adjusting the height of the handrail 32, first loosen the tool-free ring bolt, adjust the handrail 32 to the appropriate height, and then tighten the ring bolt to fix it.

[0056] like Figure 6 As shown, the escalator 4 includes: a base frame 41, pulleys 5 are provided on both sides of the lower end of the base frame 41, one side of the base frame 41 is connected to the bottom end of the ladder body 42 through a movable connection device, and the other side of the base frame 41 is connected to the back of the ladder body 42 through a buckle gear 43.

[0057] The main structure of escalator 4 adopts a frame structure, which is welded with 316L stainless steel square tubes and plates as a whole, and the movable parts adopt a hinge structure. The square tubes grasped on both sides of the ladder are integrated with the ladder frame, and the spacing between the square tubes on both sides is consistent with the width of the ladder steps. Escalator 4 has an angle adjustment function, which can achieve tilt in the pitch direction, consistent with the tilt direction of the support platform 2. On this basis, the angle between escalator 4 and the reference plane (the horizontal plane after tilting) has an adjustment angle range of 54° to 86°, and the adjustment step is 4°. The angle adjustment function adopts a buckle design. By clamping the adjustment cross arm of escalator 4 in different buckles, the adjustment of different inclination angles of escalator 4 can be achieved. There are 9 buckles designed on the back of escalator 4, and there is a protective rod at the bottom of the buckle to prevent slipping. There are obvious scales and logos every 4°.

[0058] The pedal depth is 60mm for easy stepping. U-shaped grooves are designed at both ends of the pedal, and fastening bolts are provided at the outer ends of the U-shaped grooves. The main beam of the escalator 4 has positioning holes 44 and corresponding scales, and the spacing of the positioning holes 44 is 50mm. Through the above gear adjustment method, the ladder spacing adjustment range of the escalator 4 covers 150mm to 300mm, and the adjustment step length is 50mm. The pedal is treated with frosting technology to enhance the anti-slip performance.

[0059] The base 1 is made of 80mm*80mm*4mm 316L stainless steel square tube. The ladder is designed to bear 400kg. The overall equipment is stable and has anti-overturning function.

[0060] The present invention realizes the fixation, alignment and overall lifting of large modules such as the support platform 2, the access platform 3 and the escalator 4 through the square base 1, and the support platform 2 and the access platform 3 and the escalator 4 can be used in combination or independently by moving the slide rail 11.

[0061] The posture adjustment is achieved by combining a worm gear and a hinge. A color scale is provided to observe whether the angle is adjusted in place. The posture adjustment can be achieved by turning the adjustment handle 211 with a force not greater than 50N, thus overcoming the problems of large operating force and inconvenient adjustment.

The posture adjustment can be achieved by turning the adjustment handle 211 with a force not greater than 50N, thus overcoming the problems of large operating force and inconvenient adjustment.

[0063] By moving the handle 244 and the equidistant and evenly arranged gourd holes 245 on the cabin door 24, the installation position of the handle 244 on the cabin door 24 can be quickly adjusted. The handle 244 is provided with a spiral locking mechanism, and the handle 244 can be quickly installed and removed without fasteners, and rulers are provided on both sides of the cabin door 24 to facilitate recording the installation position.
