Description

Technical Field

[0001] The utility model relates to the technical field of dock loading and unloading, and in particular to an anti-falling-into-water device used for loading and unloading cargo at a dock. Background Art

[0002] A pier is a building at the seaside or riverside where ships or ferries dock, allowing passengers to get on and off and cargo to be loaded and unloaded. It is usually found in commercial cities with developed water and land transportation. Humans use piers as a place for ferries to dock and pick up passengers and cargo, and secondly, they may be landmarks to attract tourists and meet for appointments. Common buildings or facilities around piers include cruise ships, ferries, container ships, warehouses, customs, pontoons, fish markets, seaside promenades, stations, restaurants, or shopping malls.

[0003] For example, a Chinese patent document with publication number CN218667384U discloses an anti-falling-water device for cargo loading and unloading at a dock, including a dock side platform, a support column is fixedly installed at the lower end of the dock side platform, a protective mechanism is arranged at the upper end of the dock side platform, extension mechanisms are arranged on the left and right sides of the dock side platform, a support base is fixedly installed on the outer wall of the dock side platform, and multiple support bases are evenly distributed on the outer wall of the dock side platform from front to back, and a steel frame is fixedly installed on each support base.

[0004] In the above technical solution, the guardrail structure composed of a supporting base, a steel frame and a protective crossbar has an effective barrier effect. At the same time, the protective net structure composed of an installation rod and a shielding rope body effectively expands the area of ​​the dock side platform, and catches the goods or workers falling from the dock through the extension mechanism to prevent the goods or workers from falling into the water.

[0005] However, in the above technical solution, there is a height difference between the dock side platform and the extension mechanism. When the goods fall onto the extension mechanism, it is not convenient to move the goods on the extension mechanism back to the dock. If workers are arranged to actively step onto the extension mechanism to pick up the goods that fall on the extension mechanism, the workers will actively face the risk of falling into the water. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an anti-falling-into-water device for loading and unloading cargo at a dock, which can enable the expansion table to be raised and lowered so as to facilitate the transport of fallen cargo back to the dock.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-falling-into-water device for loading and unloading cargo at a dock, characterized in that it includes a dock side platform, a support column is provided at the bottom of the dock side platform, a first fence is provided on the dock side platform, the first fence includes a first cross bar and a first vertical bar, the first vertical bar is multiple and fixed to the dock side platform at intervals, the two ends of the first cross bar are respectively fixed to the first vertical bars on both sides, the first fence is connected to a lifting mechanism, the lifting mechanism is connected to an expansion platform, and the lifting mechanism is used to drive the expansion platform to rise and fall to adjust the height difference between the expansion platform and the dock side platform.

[0008] The utility model is further configured as follows: the lifting mechanism includes a connecting seat, the connecting seat is fixed to the first vertical rod, a lead screw arranged in the vertical direction is provided in the connecting seat, the end of the lead screw is rotatably connected to the connecting seat, the outer periphery of the lead screw is sleeved and fixed to a connecting block, the connecting block and the outer periphery of the lead screw form a threaded fit, the expansion platform is fixed to the connecting block, and a driving motor is provided on one side of the connecting seat, and the driving motor is used to drive the lead screw to rotate so as to lift and lower the expansion platform.

[0009] The utility model is further configured as follows: guide seats are provided on both sides of the connecting seat, the guide seats are fixed to the first vertical rod, guide rods arranged along the vertical direction are provided in the guide seats, guide blocks are provided on both sides of the connecting block, the guide blocks are sleeved on the outer periphery of the guide rods, and can form a sliding fit with the guide rods.

[0011] The utility model is further configured as follows: a buffer pad is sleeved on the top end of the second vertical rod, and a buffer sleeve is sleeved on the outer periphery of the second cross rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Since the expansion platform is connected to the lifting mechanism and the expansion platform is lifted by the lifting mechanism, the height difference between the expansion platform and the dock platform can be reduced, so that the goods that have fallen onto the expansion platform can be easily transported to the dock again. Therefore, the technical problem in the prior art that it is inconvenient to transport the goods on the expansion platform due to the height difference between the expansion platform and the dock platform is effectively solved. In addition, the expansion platform can be driven down by the lifting mechanism so that the expansion platform can contact the water surface to support the fallen goods or people and prevent the fallen goods or people from continuing to dive.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0019] like Figures 1 to 3 As shown, the utility model discloses an anti-falling-into-water device for loading and unloading cargo at a dock, comprising a dock side platform 1, a supporting column 8 is arranged at the bottom of the dock side platform 1, a first fence 2 is arranged on the dock side platform 1, the first fence 2 comprises a first cross bar 21 and a first vertical bar 22, the first vertical bar 22 is multiple and fixed to the dock side platform 1 at intervals, the two ends of the first cross bar 21 are respectively fixed to the first vertical bars 22 on both sides, the first fence 2 is connected with a lifting mechanism, the lifting mechanism is connected with an expansion platform 3, the lifting mechanism is used to drive the expansion platform 3 to rise and fall, so as to adjust the height difference between the expansion platform 3 and the dock side platform 1, and the lifting mechanism drives the expansion platform 3 to rise and fall, so as to reduce the height difference between the expansion platform 3 and the dock side platform 1, so as to facilitate the cargo that falls on the expansion platform 3 to be transported back to the dock, and in addition, the lifting mechanism can drive the expansion platform 3 to descend, so that the expansion platform 3 can contact the water surface, so as to support the fallen cargo or people, and prevent the fallen cargo or people from continuing to dive.

[0020] In this embodiment, the specific structure of the lifting mechanism includes a connecting seat 41, which is fixed to the first vertical rod 22. A lead screw 42 is arranged in the connecting seat 41 along the vertical direction. The end of the lead screw 42 is rotatably connected to the connecting seat 41. The outer periphery of the lead screw 42 is fixedly sleeved with a connecting block 43. The connecting block 43 and the outer periphery of the lead screw 42 form a threaded fit. The expansion platform 3 is fixed to the connecting block 43. A driving motor 44 is provided on one side of the connecting seat 41. The driving motor 44 is used to drive the lead screw 42 to rotate so as to lift the expansion platform 3. When it is necessary to drive the expansion platform 3 to be lifted, the lead screw 42 is driven to rotate by the driving motor 44, so that the connecting block 43 sleeved on the outer periphery of the lead screw 42 and threadedly matched with the lead screw 42 can move along the direction of the lead screw 42 as the lead screw 42 rotates, so that the expansion platform 3 connected to the connecting block 43 can be driven to be lifted.

[0021] In addition, in order to ensure the stability of the connection block 43 moving along the direction of the lead screw 42 as the lead screw 42 rotates, guide seats 5 are provided on both sides of the connection seat 41, and the guide seats 5 are fixed to the first vertical rod 22. A guide rod 6 arranged along the vertical direction is provided in the guide seat 5. Guide blocks are provided on both sides of the connection block 43, and the guide blocks are mounted on the outer periphery of the guide rod 6 and can form a sliding fit with the guide rod 6. Therefore, in the process of the connection block 43 rotating with the lead screw 42, a sliding fit can be formed between the guide block and the guide rod 6, thereby guiding the moving path of the connection block 43 and ensuring that the connection block 43 moves along the direction of the lead screw 42. It should also be noted that the connection block 43 is connected to the top position of the expansion platform 3, so that a gap is left between the connection block 43 and the bottom of the expansion platform 3, thereby avoiding direct contact between the connection block 43 and the water surface, thereby reducing the corrosion of the connection block 43 by the water team and extending the service life of the lifting mechanism as a whole.

[0022] In this embodiment, a second fence 7 is further provided on the expansion platform 3. The second fence 7 includes a second cross bar 71 and a second vertical bar 72. The second vertical bars 72 are multiple and fixed to the expansion platform 3 at intervals. Both ends of the second cross bar 71 are respectively fixed to the second vertical bars 72 on both sides. Through the setting of the second fence 7, the goods that fall onto the expansion platform 3 can be limited to prevent the goods that fall onto the expansion platform 3 from falling again.

[0023] In this embodiment, a buffer pad 721 is further mounted on the top of the second vertical rod 72, and a buffer sleeve 711 is mounted on the outer periphery of the second horizontal rod 71. The buffer pad 721 and the buffer sleeve 711 can reduce the damage caused by a falling person or cargo hitting the second fence 7, thus making the overall design more reasonable. The buffer pad 721 and the buffer sleeve 711 are specifically made of rubber.

[0024] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
