Description

Technical Field

[0001] This utility model relates to the technical field of helicopter landing pads, specifically a detachable aluminum alloy loading and unloading platform for docks. Background Technology

[0002] A wharf is a place in a body of water such as rivers, lakes, and seas where ships can berth, load and unload cargo, embark and disembark passengers, and conduct related water operations. It typically consists of two main parts: the water area, including the harbor basin and waterways, used for the entry, exit, and berthing of ships; and the land area, including the wharf embankment, storage yards, warehouses, loading and unloading equipment, and supporting production and living facilities, used for the loading, unloading, storage, and transportation of goods and the gathering and dispersal of personnel. Wharves are hubs of water and land transportation, an important component of ports, and play a crucial role in logistics, foreign trade, and tourism.

[0003] When a wharf suffers explosive damage, semi-circular craters are likely to appear at the edges. There are certain time constraints for emergency repairs, and repair machinery is difficult to reach. The load-bearing structure used in traditional technology is basically a steel structure. Since the specific gravity of steel is three times that of aluminum alloy, large machinery is required for on-site construction. However, the site is difficult for machinery to reach, which seriously affects the time required for wharf repairs. Because steel structures are mostly connected by welding and high-strength bolts, they have low disassembly and assembly capabilities and are not conducive to reuse. Utility Model Content

[0004] The purpose of this utility model is to provide a detachable aluminum alloy loading and unloading platform for docks, which solves the problem of low dock repair efficiency. It eliminates the need for large-scale site machinery to assist in repairs, improves the efficiency of dock repairs, and facilitates subsequent reuse, thereby reducing the cost of dock repairs.

[0005] To achieve the above objectives, the utility model employs the following technical solution:

[0006] A detachable aluminum alloy loading and unloading platform for docks includes a loading and unloading platform installed in a slope damage pit at the dock. The loading and unloading platform includes a first transverse support beam and a second transverse support beam installed on the slope damage pit, and several main longitudinal beams detachably connected to the first transverse support beam and the second transverse support beam. The first transverse support beam and the second transverse support beam are both spliced ​​from several segments. Several panels are laid on the main longitudinal beams. Support piers are provided in the slope damage pit. Several telescopic outriggers are rotatably connected to the second transverse support beams. The ends of the telescopic outriggers are detachably connected to the support piers. The first transverse support beam, the second transverse support beam, and the main longitudinal beams are all made of aluminum alloy. The platform also includes a ramp connected to the main longitudinal beams.

[0007] Furthermore, the support pier is made of plain concrete. The innermost side of the slope damage pit and both sides of the edge are respectively dug and filled with a first plain concrete beam and a second plain concrete beam. The first plain concrete beam and the second plain concrete beam are detachably connected to the first transverse support beam and the second transverse support beam, respectively.

[0008] Furthermore, the first transverse support beam includes two I-beam slide rails, and the two sides of the I-beam slide rails are provided with first fixing ears, which are detachably connected to the first plain concrete beam.

[0009] Furthermore, the second transverse support beam includes two aluminum alloy channel steels, and the telescopic outrigger includes an upper mounting support rotatably connected to the two aluminum alloy channel steels, a lower mounting support detachably connected to the support pier, and a hydraulic lifting cylinder disposed between the upper mounting support and the lower mounting support.

[0010] Furthermore, the upper mounting support is provided with a shaft pin that is rotatably connected to the hydraulic lifting cylinder, the lower mounting support is provided with a sliding groove, the bottom of the hydraulic lifting cylinder is provided with a slider that is slidably connected to the sliding groove, and also includes a fixing bolt. The slider and the lower mounting support are provided with a first through hole and a second through hole for the fixing bolt to pass through.

[0011] Furthermore, a hand-cranked winch is provided on the second transverse support beam, a lifting lug is provided on one side of the hydraulic lifting cylinder, and a wire rope connected to the lifting lug is provided on the hand-cranked winch.

[0012] Furthermore, both sides of the main longitudinal beam are provided with first L-shaped fixing ears. The vertical side of the first L-shaped fixing ear is detachably connected to the main longitudinal beam, and the horizontal side of the first L-shaped fixing ear is detachably connected to the second transverse support beam. It also includes several second L-shaped fixing ears detachably disposed at the bottom of the main longitudinal beam. One side of the several second L-shaped fixing ears is simultaneously in contact with the second transverse support beam.

[0013] Furthermore, the bottom of the panel is provided with reinforcing ribs, one side of the panel is provided with a regular L-shaped block with a groove, and the other side of the panel is provided with an inverted L-shaped block with a protrusion that slides in contact with the groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Both the first and second transverse support beams are spliced ​​from several sections, which facilitates the transportation and installation of the first and second transverse support beams. Specifically, the first and second transverse support beams are first assembled transversely on one side of the slope damage pit. After the two are assembled, small lifting platform vehicles are placed on both sides of the slope damage pit, and the first and second transverse support beams are placed on them. The vehicles are then moved longitudinally to adjust the positions of the first and second transverse support beams, thereby laying the first and second transverse support beams transversely on the slope damage pit. The first transverse support beam is positioned close to the edge of the slope damage pit, and the two ends of the second transverse support beam rest on both sides of the front edge of the damage pit. This eliminates the need for large hoisting equipment, thereby shortening the time required for transporting and assembling equipment, improving the efficiency of laying and unloading platforms, and thus improving the efficiency of emergency repairs at the dock.

[0016] 2. Next, rotate the telescopic outriggers on the second transverse support beam until they are in a vertical position. At the same time, adjust the length of the telescopic outriggers so that they contact the supports set in the slope damage pit. Then, use bolts to connect the supports and the telescopic outriggers to complete the assembly of the telescopic outriggers. Meanwhile, the telescopic outriggers are evenly distributed on the second transverse support beam to absorb the vertical force borne by the second transverse support beam, make up for the defects caused by the insufficient strength of the aluminum alloy material, improve the overall load-bearing capacity of the loading and unloading platform, and ensure the normal passage of vehicles and goods.

[0017] 3. Finally, the main longitudinal beam is erected longitudinally on the first and second transverse support beams. The main longitudinal beam is then bolted to the first and second transverse support beams. The panel is then laid on top of the support beams. Planks are installed around the loading and unloading platform to ensure the normal passage of vehicles and goods. Since the first, second, and main longitudinal beams are all made of aluminum alloy, which is one-third the weight of steel, the overall weight of the loading and unloading platform is relatively light. This eliminates the need for large lifting equipment, thereby shortening the time required for transporting and assembling the equipment, improving the efficiency of laying the loading and unloading platform, and ultimately improving the efficiency of emergency dock repairs.

Detailed Implementation

[0031] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0032] This utility model provides a detachable aluminum alloy loading and unloading platform for docks, such as... Figure 1 , Figure 2 and Figure 3As shown, the loading and unloading platform includes a loading platform set up in the slope damage pit 1 of the wharf. The loading and unloading platform includes a first transverse support beam 2 and a second transverse support beam 3 set on the slope damage pit 1, and several main longitudinal beams 4 detachably connected to the first transverse support beam 2 and the second transverse support beam 3. The first transverse support beam 2 and the second transverse support beam 3 are both spliced ​​from several sections to facilitate transportation and installation. Specifically, the first transverse support beam 2 and the second transverse support beam 3 are first assembled transversely on one side of the slope damage pit 1. After the two are assembled, small... The lifting platform vehicle places the first transverse support beam 2 and the second transverse support beam 3 on top of it, and drives it to move longitudinally. The positions of the first transverse support beam 2 and the second transverse support beam 3 are adjusted, so that the first transverse support beam 2 and the second transverse support beam 3 are laid on the slope damage pit 1 in the transverse direction, respectively. The first transverse support beam 2 is set close to one side of the edge of the slope damage pit 1, and the two ends of the second transverse support beam 3 are placed on both sides of the front edge of the slope damage pit 1. There is no need to use large hoisting equipment, thereby shortening the time required for transporting and assembling equipment, improving the efficiency of laying loading and unloading platforms, and thus improving the efficiency of emergency repair of the dock.

[0033] Several panels 5 are laid on the main longitudinal beam 4. Supports 6 are installed within the slope damage pit 1. Several telescopic outriggers 7 are rotatably connected to the second transverse support beam 3. The telescopic outriggers 7 are evenly distributed on the second transverse support beam 3 to absorb the vertical force borne by the second transverse support beam 3, compensate for the insufficient strength of the aluminum alloy material, improve the overall load-bearing capacity of the loading and unloading platform, and ensure the normal passage of vehicles and goods. The ends of the telescopic outriggers 7 are detachably connected to the supports 6. The first transverse support beam 2, the second transverse support beam 3, and the main longitudinal beam 4 are all made of aluminum alloy. It also includes a scaffold 8 connected to the main longitudinal beam 4, rotating the telescopic outrigger 7 on the second transverse support beam 3 until it is in a vertical state, and adjusting the length of the telescopic outrigger 7 so that it contacts the support pier 6 set in the slope damage pit 1. Then, the support pier 6 and the telescopic outrigger 7 are connected with bolts to realize the assembly of the telescopic outrigger 7. At the same time, the telescopic outrigger 7 is evenly distributed on the second transverse support beam 3 to absorb the vertical force borne by the second transverse support beam 3, make up for the defects caused by the insufficient strength of aluminum alloy material, improve the overall load-bearing capacity of the loading and unloading platform, and ensure the normal passage of vehicles and goods.

[0034] Finally, the main longitudinal beam 4 is erected longitudinally on the first transverse support beam 2 and the second transverse support beam 3. The main longitudinal beam 4 is then bolted to the first transverse support beam 2 and the second transverse support beam 3. The panel 5 is then laid on top of the support beams. At the same time, ramps 8 are set around the loading and unloading platform to ensure the normal passage of vehicles and goods. Since the first transverse support beam 2, the second transverse support beam 3 and the main longitudinal beam 4 are all made of aluminum alloy, which has a specific gravity of 1 / 3 that of steel, the overall weight of the loading and unloading platform is relatively light. Large hoisting equipment is not required, which shortens the time required for transporting and assembling equipment, improves the efficiency of laying the loading and unloading platform, and thus improves the efficiency of emergency repairs at the dock.

[0035] Preferred, such as Figure 4 As shown, the support pier 6 is made of plain concrete. A first plain concrete beam 9 and a second plain concrete beam 10 are dug and poured at the innermost side and on both sides of the edge of the slope damage pit 1. The first plain concrete beam 9 and the second plain concrete beam 10 are detachably connected to the first transverse support beam 2 and the second transverse support beam 3, respectively. A small excavator is used to roughly level the ground around the combined platform area of ​​the slope damage pit 1. A pit is dug and plain concrete is poured near the edge of the slope damage pit 1 where the first transverse support beam 2 is erected, thus forming the first plain concrete beam 9. Similarly, the second transverse support beam 3 is set on both sides of the front edge of the slope damage pit 1. The support pier 6 is then constructed using concrete. Plain concrete beams can withstand bending moments and shear forces, have high compressive strength, and can withstand greater pressure, thereby improving the bearing capacity of the corresponding location of the slope damage pit 1. This allows the first plain concrete beam 9, the second plain concrete beam 10, and the pier 6 to absorb the vertical force carried by the loading and unloading platform, preventing the edge of the slope damage pit 1 from being overloaded and collapsing again, thus improving the safety of the loading and unloading platform during use. In addition, since plain concrete beams are made by mixing cement, sand, gravel, admixtures, and water in a certain proportion, they are mainly composed of concrete and contain no steel reinforcement or only a small amount of structural steel reinforcement. This makes the construction process relatively simple, eliminating the need for complex procedures such as steel reinforcement binding and positioning, further improving the efficiency of emergency repair of the wharf.

[0036] Preferred, such as Figure 5 and Figure 6 As shown, the first transverse support beam 2 includes two I-beam slide rails 11. The two sides of the I-beam slide rails 11 are provided with first fixing ears 12. The first fixing ears 12 are detachably connected to the first plain concrete beam 9. The first fixing ears 12 are fixed to the first plain concrete beam 9 by expansion bolts, thereby fixing the first transverse support beam 2 to the first plain concrete beam 9. At the same time, since the first plain concrete beam 9 includes two I-beam slide rails 11, it can be temporarily used as a slide rail to transport the main longitudinal beam 4, shortening the time required to transport the main longitudinal beam 4 and further improving the efficiency of emergency repair of the dock.

[0037] Preferred, such as Figure 7 and Figure 10 As shown, the second transverse support beam 3 includes two aluminum alloy channel steels 13. The aluminum alloy channel steels 13 have high strength and rigidity, enabling them to withstand large vertical loads and further improving the load-bearing capacity of the loading and unloading platform. Simultaneously, the density of aluminum alloy is 1 / 3 that of steel, facilitating installation and transportation, thereby improving the efficiency of emergency dock repairs. The telescopic outrigger 7 includes an upper mounting support 14 detachably connected to the two aluminum alloy channel steels 13, a lower mounting support 15 detachably connected to the support pier 6, and supports disposed on the upper mounting support 14 and the lower mounting support 15. The hydraulic lifting cylinder 16 between the supports 15 rotates between the two upper mounting supports 14 and the aluminum alloy channel steel 13, which can change the angle between the telescopic outrigger 7 and the second transverse support beam 3, facilitating subsequent installation and retrieval. The hydraulic lifting cylinder 16 provides power for the telescopic outrigger 7 to extend and retract, so that the lower mounting supports 15 can be connected to the support 6. This is used to absorb the vertical force carried by the second transverse support beam 3, make up for the defects caused by the insufficient strength of the aluminum alloy material, improve the overall load-bearing capacity of the loading and unloading platform, and ensure the normal passage of vehicles and goods.

[0038] Preferred, such as Figure 10 As shown, the upper mounting support 14 is provided with a pin 17 that is rotatably connected to the hydraulic lifting cylinder 16. Specifically, the pin 17 passes through the hydraulic lifting cylinder 16 and is welded to the upper mounting support 14. The lower mounting support 15 is provided with a sliding groove 18. The bottom of the hydraulic lifting cylinder 16 is provided with a slider 19 that is slidably connected to the sliding groove 18. It also includes a fixing bolt 20. The slider 19 and the lower mounting support 15 are provided with a first through hole 21 and a second through hole 22 for the fixing bolt 20 to pass through. After the slider 19 at the bottom of the hydraulic lifting cylinder 16 is slid into the sliding groove 18 provided in the lower mounting support 15, the fixing bolt 20 passes through the corresponding first through hole 21 and second through hole 22 in sequence. The two ends of the fixing bolt 20 are connected with nuts, thereby realizing the connection between the hydraulic lifting cylinder 16 and the lower mounting support 15.

[0039] Preferred, such as Figure 9 and Figure 10 As shown, a hand-cranked winch 23 is provided on the second transverse support beam 3, and a lifting lug 24 is provided on one side of the hydraulic lifting cylinder 16. A steel wire rope 25 connected to the lifting lug 24 is provided on the hand-cranked winch 23. By rotating the hand-cranked winch 23, the steel wire rope 25 is loosened and tightened, thereby adjusting the angle of the telescopic outrigger 7 so that its end is completely in contact with the support 6, thereby improving the load-bearing capacity of the loading and unloading platform.

[0040] Preferred, such as Figure 8As shown, the main longitudinal beam 4 is provided with first L-shaped fixing ears 26 on both sides. The vertical side of the first L-shaped fixing ears 26 is detachably connected to the main longitudinal beam 4, and the horizontal side of the first L-shaped fixing ears 26 is detachably connected to the second transverse support beam 3, thereby realizing the detachable connection between the main longitudinal beam 4 and the second transverse support beam 3. It also includes several second L-shaped fixing ears 27 detachably set at the bottom of the main longitudinal beam 4. One side of several second L-shaped fixing ears 27 simultaneously contacts the second transverse support beam 3, restricting the support beam from moving longitudinally on the second transverse support beam 3, thereby improving the stability of the overall structure of the loading and unloading platform and improving the load-bearing capacity of the loading and unloading platform.

[0041] Preferred, such as Figure 11 As shown, the bottom of the panel 5 is provided with reinforcing ribs 28 to further enhance the load-bearing capacity of the panel 5, thereby improving the load-bearing capacity of the loading and unloading platform. One side of the panel 5 is provided with a regular L-shaped block 29, and the regular L-shaped block 29 is provided with a groove 30. The other side of the panel 5 is provided with an inverted L-shaped block 31, and the inverted L-shaped block 31 is provided with a protrusion 32 that slides in contact with the groove 30. One panel 5 is placed on the side of another panel 5 from top to bottom, so that the inverted L-shaped block 31 on one panel 5 is inserted into the regular L-shaped block 29 on the other panel 5, and the protrusion 32 on the inverted L-shaped block 31 enters into the groove 30 on the regular L-shaped block 29. The resistance generated after the two come into contact restricts the relative horizontal movement of the two panels 5, thereby realizing the detachable connection between the panels 5, simplifying the operation steps of connecting the panels 5, and thus improving the construction efficiency of the loading and unloading platform.

[0042] Example 1

[0043] This utility model provides a detachable aluminum alloy loading and unloading platform for docks, such as... Figure 1 , Figure 2 and Figure 3 As shown, several telescopic outriggers 7 are pre-installed on the second transverse support beam 3, and support piers 6 are installed in the slope damage pit 1.

[0044] The first transverse support beam 2 and the second transverse support beam 3 are both spliced ​​from several sections, which facilitates the transportation and installation of the first transverse support beam 2 and the second transverse support beam 3. First, the first transverse support beam 2 and the second transverse support beam 3 are assembled transversely on one side of the slope damage pit 1. After the two are assembled, small lifting platform vehicles are placed on both sides of the slope damage pit 1, and the first transverse support beam 2 and the second transverse support beam 3 are placed on them. The vehicles are moved longitudinally to adjust the position of the first transverse support beam 2 and the second transverse support beam 3, so that the first transverse support beam 2 and the second transverse support beam 3 are laid transversely on the slope damage pit 1 respectively. The first transverse support beam 2 is set close to the edge of the slope damage pit 1, and the two ends of the second transverse support beam 3 are placed on both sides of the front edge of the slope damage pit 1. Large hoisting equipment is not required, which shortens the time required for transporting and assembling equipment, improves the efficiency of laying and unloading platforms, and thus improves the efficiency of emergency repair of the dock.

[0045] Next, rotate the telescopic outrigger 7 on the second transverse support beam 3 until it is in a vertical position. At the same time, adjust the length of the telescopic outrigger 7 so that it contacts the support 6 set in the slope damage pit 1. Then, use bolts to connect the support 6 and the telescopic outrigger 7 to assemble the telescopic outrigger 7. Meanwhile, the telescopic outrigger 7 is evenly distributed on the second transverse support beam 3 to absorb the vertical force borne by the second transverse support beam 3, make up for the defects caused by the insufficient strength of the aluminum alloy material, improve the overall load-bearing capacity of the loading and unloading platform, and ensure the normal passage of vehicles and goods.

[0046] Finally, the main longitudinal beam 4 is erected longitudinally on the first transverse support beam 2 and the second transverse support beam 3. The main longitudinal beam 4 is then bolted to the first transverse support beam 2 and the second transverse support beam 3. The panel 5 is then laid on top of the support beams. At the same time, ramps 8 are set around the loading and unloading platform to ensure the normal passage of vehicles and goods. Since the first transverse support beam 2, the second transverse support beam 3 and the main longitudinal beam 4 are all made of aluminum alloy, which has a specific gravity of 1 / 3 that of steel, the overall weight of the loading and unloading platform is relatively light. Large hoisting equipment is not required, which shortens the time required for transporting and assembling equipment, improves the efficiency of laying the loading and unloading platform, and thus improves the efficiency of emergency repairs at the dock.

[0047] Example 2

[0048] Based on Example 1, such as Figures 4-8As shown, small excavators were used to roughly level the ground around the combined platform area where the slope damage pit 1 was to be erected. A pit was dug near the edge of the slope damage pit 1 where the first transverse support beam 2 was to be erected, and plain concrete was poured to form the first plain concrete beam 9. Similarly, second transverse support beams 3 were set on both sides of the front edge of the slope damage pit 1, and concrete supports 6 were poured. Because plain concrete beams can withstand bending moments and shear forces, and have high compressive strength, they can withstand greater pressure, thereby improving the bearing capacity of the corresponding location of the slope damage pit 1. This allows the first plain concrete beam 9, the second plain concrete beam 10, and the supports 6 to absorb the vertical force carried by the loading and unloading platform, preventing the edge of the slope damage pit 1 from collapsing due to excessive load, thus improving the safety of the loading and unloading platform during use. Furthermore, since plain concrete beams are made by mixing cement, sand, gravel, and admixtures with water in a specific ratio, and are mainly composed of concrete with no or only a small amount of structural steel reinforcement, the construction process is relatively simple, eliminating the need for complex procedures such as steel reinforcement binding and positioning, further improving the efficiency of the emergency repair of the wharf.

[0049] The first fixing lug 12 is fixed to the first plain concrete beam 9 by expansion bolts, thereby fixing the first transverse support beam 2 to the first plain concrete beam 9. At the same time, since the first plain concrete beam 9 includes two I-beam slide rails 11, it can be temporarily used as slide rails to transport the main longitudinal beam 4, shortening the time required to transport the main longitudinal beam 4 and further improving the efficiency of emergency repair of the dock.

[0050] The second transverse support beam 3 includes two aluminum alloy channel steels 13. The aluminum alloy channel steels 13 have high strength and rigidity, and can withstand large vertical loads, further improving the load-bearing capacity of the loading and unloading platform. At the same time, the density of aluminum alloy is 1 / 3 that of steel, which facilitates installation and transportation, thereby improving the efficiency of emergency repair of the dock.

[0051] Example 3

[0052] Based on Example 2, such as Figure 9 and Figure 10As shown, when assembling the telescopic outrigger 7 on the second transverse support beam 3, the upper mounting bracket 14 is first detachably installed between the two aluminum alloy channel steels 13 to connect the upper mounting bracket 14 with the second transverse support beam 3. Then, the slider 19 at the bottom of the hydraulic lifting cylinder 16 is slid into the groove 18 on the lower mounting bracket 15. After the fixing bolts 20 pass through the corresponding first through hole 21 and second through hole 22 in sequence, the two ends of the fixing bolts 20 are connected with nuts, thereby connecting the hydraulic lifting cylinder 16 with the lower mounting bracket. The connection of seat 15; finally, the axle pin 17 is passed through the hydraulic lifting cylinder 16 and welded to the upper mounting support 14, thereby assembling the telescopic outrigger 7 on the second transverse support beam 3. Then, the hydraulic lifting cylinder 16 provides power for the telescopic outrigger 7 to extend and retract, while the hand winch 23 is turned to loosen and tighten the wire rope 25, thereby adjusting the angle of the telescopic outrigger 7 so that the end of the telescopic outrigger 7 is completely in contact with the support 6, thereby compensating for the defects caused by the insufficient strength of the aluminum alloy material, improving the overall load-bearing capacity of the loading and unloading platform, and ensuring the normal passage of vehicles and goods.

[0053] Example

[0054] Based on Example 1, such as Figure 11 As shown, the bottom of panel 5 is provided with reinforcing ribs 28 to further enhance the load-bearing capacity of panel 5, thereby improving the load-bearing capacity of the loading and unloading platform. When two panels 5 need to be connected, one panel 5 is placed on the side of the other panel 5 from top to bottom, so that the inverted L-shaped block 31 on one panel 5 is inserted into the regular L-shaped block 29 on the other panel 5, and the protrusion 32 on the inverted L-shaped block 31 enters into the groove 30 on the regular L-shaped block 29. The resistance generated after the two come into contact restricts the relative horizontal movement of the two panels 5, thereby realizing the detachable connection between the panels 5, simplifying the operation steps of connecting the panels 5, and thus improving the construction efficiency of the loading and unloading platform.
