Description

Technical Field

[0001] This utility model relates to the field of devices and equipment, and in particular to a boarding bridge that is adaptable to various types of carriages. Background Technology

[0002] Hydraulic loading ramps are specialized auxiliary equipment for rapid loading and unloading of goods. Their height adjustment function bridges the gap between trucks and warehouse loading platforms, allowing forklifts and other handling vehicles to directly drive into the trucks for bulk loading and unloading of goods. Only one person is needed to operate the equipment, enabling rapid loading and unloading of goods.

[0003] However, due to the varying sizes of freight truck beds, the loading ramp's lip plate cannot be designed very wide to ensure it can accommodate different sized beds for loading and unloading. It is typically limited to a width of no more than 2 meters, allowing for loading of all sizes. However, this design has a drawback: when medium or large trucks arrive at the platform, their beds are wider (2-3 meters), but due to the lip plate width limitation, the main board width cannot exceed 2 meters. Therefore, similar to small trucks, only a 2-meter wide unloading aisle is available, significantly reducing the efficiency of forklifts and pallet trucks in loading and unloading. Therefore, our company has broken with the original loading ramp design width and designed a loading ramp that can adapt to different truck beds depending on the situation. Utility Model Content

[0022] The present invention will be further described below: A loading ramp adapted to various carriage models includes a base 1, a main board 2, and a lip plate 3. See [link to relevant documentation]. Figures 1 to 3 The lip plate 3 consists of a main lip plate 31 and two auxiliary lip plates 32. The auxiliary lip plates 32 are 0.5m wide and are located on the left and right sides of the main lip plate 31. The main lip plate 31 and the auxiliary lip plates 32 are rotatably connected to the front end of the main plate 2. The bottom of the main plate 2 is provided with three auxiliary hydraulic cylinders 5 that drive the main lip plate 31 and the auxiliary lip plates 32 to rotate independently. One end of the auxiliary hydraulic cylinder 5 is rotatably connected to the main plate 2 through a hinge seat, and the other end is connected to the middle of the lip plate 3 through a rotating arm 10. This utility model adds two auxiliary lip plates 32 to the original lip plate 3, and both auxiliary lip plates 32 can be independently flipped and opened, so that the lip plate 3 of the appropriate width can be opened according to the size of the cargo box of different trucks and extended into the cargo box to realize the erection of the loading ramp. Furthermore, thanks to the design of the auxiliary lip plate 32, the original width limitation of the main plate 2 is overcome, allowing the main plate 2 to be designed to be wider. Combined with the opening of the auxiliary lip plate 32, this provides the widest loading and unloading passage for medium and large trucks, enabling multiple handling vehicles to load simultaneously and effectively accelerating loading and unloading efficiency. Moreover, the addition of the auxiliary lip plate 32 and the bottom auxiliary hydraulic cylinder 5 increases the bridging strength between the main plate 2 and the truck bed, facilitating the simultaneous entry of multiple handling vehicles into the truck bed via the loading ramp.

[0023] This utility model achieves adaptation to different sized carriages through the design of an independent secondary lip plate 32. The specific adaptation method is as follows:

[0024] When the truck is a small truck, its cargo box is usually 2m wide. Simply start the auxiliary cylinder at the bottom of the main lip plate 31 to flip the main lip plate 31 up to a width of nearly 2m, and then extend it into the cargo box to load and unload the cargo of the small truck.

[0025] When the truck is a medium-sized truck with a cargo box of 2.5m, while the main lip plate 31 is flipped up, one of the auxiliary lip plates 32 on the left or right side is also flipped up to reach a lip plate 3 width of nearly 2.5m. Then, it can be inserted into the cargo box to load and unload goods from the medium-sized truck.

[0026] When the truck is a large truck with a cargo box of about 3m, the two auxiliary lip plates 32 are flipped up at the same time as the main lip plate 31 is flipped up, reaching a lip plate width of nearly 3m, and then extended into the cargo box, so that the loading and unloading of goods of the large truck can be carried out.

[0027] Loading ramps are typically installed under the platform. The main board 2 needs to be flipped up by the main hydraulic cylinder 4 to connect with the freight car body. Therefore, there is a main hydraulic cylinder 4 between the base 1 and the main board 2, which is responsible for flipping the main board 2. Its flipping drive structure is as follows:

[0028] The rear end of the main board 2 is rotatably connected to the rear end of the base 1. A main hydraulic cylinder 4 for driving the main board 2 to rotate is provided between the base 1 and the main board 2. The two ends of the main hydraulic cylinder 4 are rotatably connected to the base 1 and the main board 2 respectively through hinge seats. A pin 9 is provided at each of the front and rear ends of the main board 2. The main lip plate 31 and the secondary lip plate 32 are rotatably connected to the front pin 9 respectively. The main board 2 is rotatably connected to the rear pin 9.

[0029] To achieve drive control of the main cylinder 4 and the auxiliary cylinder 5, a hydraulic oil station 6 is provided on the base 1. The oil supply port of the hydraulic oil station 6 is connected to the oil inlet of the main cylinder 4 and the auxiliary cylinder 5 through the oil supply pipe. The oil outlet of the main cylinder 4 and the auxiliary cylinder 5 is connected to the oil tank of the hydraulic oil station 6 through the oil return pipe.

[0030] To achieve independent drive control of the main cylinder 4 and the auxiliary cylinder 5, the hydraulic oil station 6 is an integrated pump station with control, branded as Sanhao, and adopts a four-pipeline oil supply. The four oil supply pipelines are respectively connected to the oil inlets of the main cylinder 4 and the auxiliary cylinder 5.

[0031] After the mainboard 2 is flipped up, in order to improve the structural stability between the mainboard 2 and the base 1 and improve the safety of the transport vehicle, this utility model also provides a support rod 8 between the mainboard 2 and the base 1. A slot seat is welded to the bottom of the mainboard 2. The lower end of the support rod 8 is rotatably connected to the base 1, and the upper end is engaged with the slot seat at the bottom of the mainboard 2. The support rod 8 can reduce the load requirement on the main hydraulic cylinder 4. After the mainboard 2 is flipped into place, the support rod 8 is flipped up and engaged with the bottom of the mainboard 2, which can improve the load capacity and safety of the mainboard 2, so that multiple transport vehicles can enter and exit at the same time.

[0032] The mainboard 2 is also equipped with a foldable fan-shaped baffle 7 on both its left and right sides. The fan-shaped baffle 7 is composed of multiple stacked strip baffles, with their rear ends rotatably connected via a rotating shaft. The front end of each strip baffle is equipped with a limiting screw 71 or an arc-shaped sliding groove 72. Adjacent strip baffles are sequentially connected via the limiting screw 71 and the sliding groove 72. The limiting screw 71 is located within the sliding groove 72 and is slidably connected to it. When the mainboard 2 is flipped open, the strip baffles automatically open due to their own weight, forming a fan-shaped area that can shield the area below the mainboard 2, preventing operators from accidentally entering underneath and causing a safety accident.

[0033] The above provides a detailed description of a boarding ramp adapted to various carriage models. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, based on the idea of ​​this utility model, there will be changes in the specific implementation and application scope. Modifications and improvements to this utility model are possible without exceeding the concept and scope defined by the appended claims. Therefore, the content of this specification should not be construed as a limitation of this utility model.
