Description

Technical Field

[0001] This invention relates to the field of obstacle crossing technology for vehicle transportation, and specifically to an obstacle crossing device for a transport vehicle. Background Technology

[0002] Transport trolleys are important tools for transferring production materials and equipment within large hydropower plant buildings. In daily use, they often encounter different obstacles, such as room thresholds, temporary cables, water pipes, and oil pipes laid on the ground. These seriously hinder the smooth passage of the trolleys and affect the efficiency of work on the production site.

[0003] For example, when replacing entire battery banks in a power station's DC system, each battery bank contains over 100 individual batteries, each weighing approximately 50 kilograms (the larger the battery capacity, the heavier it is). To improve replacement efficiency, the trolley must transport at least six individual batteries at a time. Carrying such a heavy load, the trolley must be lifted both front and back to cross obstacles such as fire door thresholds, causing significant inconvenience and posing a risk of injury to workers. Furthermore, the trolley also encounters difficulties in easily crossing obstacles when transporting other heavy objects, such as iron fences or heavy metal equipment.

[0004] It is evident that the material transport trolley's current method of conveying materials still has room for improvement. It should be modified to enhance its obstacle-crossing ability and facilitate the transport of workpieces. Therefore, a more reasonable technical solution is needed to address the existing technical problems. Summary of the Invention

[0005] In response to some of the problems existing in the prior art, this invention discloses a trolley obstacle crossing device. By setting it at the obstacle to be crossed, a ramp is formed to help the trolley cross the obstacle, thereby improving the convenience of the trolley's movement and reducing the operational risks for transport personnel.

[0006] To achieve the above objectives, the obstacle-crossing device for the transport trolley disclosed in this invention can adopt the following solution: A trolley obstacle crossing device includes an inverted U-shaped plate for setting at an obstacle. A ramp is provided at the upper folded edge of the inverted U-shaped plate. The ramp is connected to the inverted U-shaped plate through a flip connector and flips vertically. The width of the ramp is greater than the span height of the inverted U-shaped plate and it is inclined to the ground to form an uphill ramp and a downhill ramp.

[0007] The aforementioned obstacle-crossing device uses an inverted U-shaped plate erected at the obstacle location to provide a support structure for overcoming the obstacle. An uphill and downhill ramp is formed by a ramp plate. During the movement of the transport vehicle, the vehicle moves uphill to a gradually rising position, then moves along the inverted U-shaped plate and descends along the downhill ramp. This improves the ease with which the transport vehicle can cross obstacles and reduces the operational risks for transport personnel.

[0008] Furthermore, a flip-up connector is used to connect the inverted U-shaped plate and the ramp plate, allowing the ramp plate to deflect longitudinally, thereby forming a ramp for the trolley to pass over. Its structure is not uniquely limited; optimization is proposed here, and one feasible option is suggested: the flip-up connector includes a hinge, with the ramp plate connecting to one flip-up portion of the hinge, and the inverted U-shaped plate connecting to the other flip-up portion of the hinge. With this solution, the hinge opening exceeds 200°, allowing the ramp plate to flip up to fit against the top of the inverted U-shaped plate, or to flip up to overlap the ground to form a ramp.

[0009] Furthermore, the required traversal height varies depending on the obstacle, necessitating greater compatibility for the inverted U-shaped plate to overcome obstacles under more conditions. Therefore, its structure is not uniquely limited. Here, we propose an optimization and one feasible option: a lifting structure is installed beneath the inverted U-shaped plate. With this solution, the lifting structure elevates the entire inverted U-shaped plate, creating a cavity beneath it that is then supported on the obstacle.

[0010] Furthermore, the lifting structure can be implemented using various methods, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the lifting structure includes lifting support plates, with at least two lifting support plates, each movably engaging with the side plates of the inverted U-shaped plate to achieve lifting and adjusting of the inverted U-shaped plate. When using this method, the length of the lifting support plate is the same as the length of the inverted U-shaped plate, facilitating overall lifting and adjusting after engagement.

[0011] Furthermore, the lifting support plate and the inverted U-shaped plate can be used in various ways for lifting, and their structure is not limited to a single one. Here, we optimize and propose one feasible option: the lifting support plate and the inverted U-shaped plate are respectively provided with several height adjustment holes, which are spaced apart in the longitudinal direction and connected and fixed by fasteners. When adopting the above solution, the fitting height can be easily adjusted by adjusting the fitting holes of the lifting support plate and the inverted U-shaped plate, and then fixed with fasteners to achieve a fixed fit.

[0012] Furthermore, in some solutions, the cooperation structure between the lifting support plate and the inverted U-shaped plate can adopt more schemes. Here, we optimize and propose one feasible option: the lifting support plate and the inverted U-shaped plate are respectively provided with height adjustment grooves, and several limiting grooves are respectively provided on the side of the height adjustment grooves. Fastening members are provided at the limiting grooves to connect and fix the lifting support plate and the inverted U-shaped plate. When the above scheme is adopted, the fastening members can be moved into the height adjustment grooves when the lifting support plate and the inverted U-shaped plate are adjusted to the corresponding appropriate positions. After the height of the lifting support plate and the inverted U-shaped groove is adjusted to the corresponding appropriate positions, the fastening members are then moved into the limiting grooves.

[0013] Furthermore, the lifting support plate, when combined with the inverted U-shaped plate, also serves to support the inverted U-shaped plate. Its supporting and fixing structure can adopt various schemes; here, we optimize and propose one feasible option: a fixed bottom edge is provided below the lifting support plate, extending horizontally to fix the lifting support plate. When the above scheme is adopted, the fixed bottom edge and the lifting support plate together form an L-shaped structure.

[0014] Furthermore, to facilitate storage, portability, and reuse after use, the device structure is optimized as follows: The ramp plate and the inverted U-shaped plate are respectively equipped with storage structures. These structures are used to secure the entire device when the ramp plate is flipped to fit against the inverted U-shaped plate. With this design, the storage structures corresponding to the ramp plate and the inverted U-shaped plate after they are fitted together can be used for hanging, binding, or other similar applications.

[0015] Furthermore, the storage structure can be constructed in various forms, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the storage structure includes grooves on both sides of the ramp plate along its length, and the inverted U-shaped plate has corresponding grooves at the same positions. When adopting the above scheme, the grooves can be semi-circular grooves, so that when the ramp plate is flipped, the grooves of the ramp plate align with the grooves of the inverted U-shaped plate.

[0016] Furthermore, in some solutions, the inverted U-shaped plate can be constructed in various forms, and its structure is not uniquely limited. Here, we optimize and propose one feasible option: the inverted U-shaped plate includes a top plate located at the top and side plates located on both sides of the top plate. The top plate and side plates are integrally formed and perpendicular to each other. When adopting the above solution, the width of the top plate of the inverted U-shaped plate can be equal to the height of the side plates.

[0017] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this invention include: This invention provides a passage for the transport vehicle to cross obstacles by forming a structure that allows it to do so, thereby reducing the difficulty of overcoming obstacles during transportation, greatly improving the convenience of transport, reducing the burden on transport personnel, and avoiding the dangers of obstacle-crossing operations.

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this embodiment.

[0022] In view of the fact that the existing technology makes it difficult for the transport vehicle to overcome obstacles during its movement and poses safety hazards, the following embodiments are optimized and overcome the defects of the existing technology.

[0023] Example like Figure 1 As shown, this embodiment provides a transport trolley obstacle crossing device, including an inverted U-shaped plate 2 for setting at the obstacle. A ramp plate 1 is provided at the upper folded edge of the inverted U-shaped plate 2. The ramp plate 1 is connected and cooperates with the inverted U-shaped plate 2 through a flip connector 3 and flips in the vertical direction. The width of the ramp plate 1 is greater than the span height of the inverted U-shaped plate 2 and is inclined to the ground to form an uphill ramp and a downhill ramp.

[0024] The obstacle-crossing device disclosed in this embodiment provides a support structure for overcoming obstacles by setting up an inverted U-shaped plate 2 at the obstacle position. An uphill and downhill ramp is formed by a ramp plate 1. During the movement of the transport trolley, the trolley reaches a gradually rising position along the uphill ramp, moves along the inverted U-shaped plate 2, and then descends along the downhill ramp. This improves the convenience of the transport trolley in crossing obstacles and reduces the operational risks for transport personnel.

[0025] Preferably, the inverted U-shaped plate 2 is made of hard and lightweight alloy or carbon fiber material, with a plate thickness of about 0.3cm, a height adjustment range of 6~10cm for the shrink plate, a design width of 15cm for the ramp plate 1 and the inverted U-shaped plate 2, and the overall length of the device should be the same as the width of the transport trolley used in conjunction with it.

[0026] The flip connector 3 connects the inverted U-shaped plate 2 and the ramp plate, allowing the ramp plate to deflect longitudinally to form a ramp for the trolley to pass over. Its structure is not uniquely limited; this embodiment optimizes and adopts one feasible option: the flip connector 3 includes a hinge, the ramp plate 1 connects to one flip portion of the hinge, and the inverted U-shaped plate 2 connects to the other flip portion of the hinge. With this solution, the hinge opening exceeds 200°, allowing the ramp plate to flip to fit against the top of the inverted U-shaped plate 2, or to flip to overlap the ground to form a ramp.

[0027] When facing different obstacles, the required crossing height will vary, necessitating that the inverted U-shaped plate 2 possess greater compatibility to overcome obstacles under more conditions. Therefore, its structure is not uniquely limited. This embodiment optimizes and adopts one feasible option: a lifting structure is provided below the inverted U-shaped plate 2. With this solution, the lifting structure is used to raise the inverted U-shaped plate 2 as a whole, forming a cavity below the inverted U-shaped plate 2 and supporting it on the obstacle.

[0028] The lifting structure can achieve lifting in various ways, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the lifting structure includes lifting support plates 4, and there are at least two lifting support plates 4, which are respectively movably engaged with the side plates 202 of the inverted U-shaped plate 2 to realize the lifting and adjusting of the inverted U-shaped plate 2. When the above scheme is adopted, the length of the lifting support plate 4 is the same as the length of the inverted U-shaped plate 2, which facilitates the overall lifting and adjusting after engagement.

[0029] The lifting support plate 4 and the inverted U-shaped plate 2 can be raised and lowered in various ways, and their structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the lifting support plate 4 and the inverted U-shaped plate 2 are respectively provided with a number of height adjustment holes, which are spaced apart in the longitudinal direction and connected and fixed by fasteners 6. When the above scheme is adopted, the fitting height can be easily adjusted by adjusting the fitting holes of the lifting support plate 4 and the inverted U-shaped plate 2, and then fixed with fasteners to achieve fitting fixation.

[0030] In some solutions, the cooperation structure between the lifting support plate 4 and the inverted U-shaped plate 2 can adopt more options. This embodiment optimizes and adopts one feasible option: the lifting support plate 4 and the inverted U-shaped plate 2 are respectively provided with height adjustment grooves 5, and the sides of the height adjustment grooves 5 are respectively provided with several limiting grooves 501. Fastening members 6 are provided at the limiting grooves 501 to connect and fix the lifting support plate 4 and the inverted U-shaped plate 2. When the above solution is adopted, the lifting support plate 4 and the inverted U-shaped plate 2 are adjusted so that the fastening members 6 can be moved into the height adjustment grooves 5. After the height of the lifting support plate 4 and the inverted U-shaped groove is adjusted to the corresponding appropriate position, the fastening members 6 are moved into the limiting grooves 501.

[0031] After the lifting support plate 4 cooperates with the inverted U-shaped plate 2, it also serves to support the inverted U-shaped plate 2. Its supporting and fixing structure can adopt various schemes; this embodiment optimizes and adopts one feasible option: a fixed bottom edge 8 is provided below the lifting support plate 4, which extends horizontally and is used to fix the lifting support plate 4. When the above scheme is adopted, the fixed bottom edge 8 and the lifting support plate 4 form an L-shaped structure.

[0032] To facilitate storage, portability, and reuse after use, this embodiment optimizes the device's structure: the ramp plate 1 and the inverted U-shaped plate 2 are respectively provided with storage structures. These storage structures are used to store and secure the entire device when the ramp plate 1 is flipped to fit against the inverted U-shaped plate 2. With this solution, the storage structures corresponding to the ramp plate 1 and the inverted U-shaped plate 2 after they are fitted together can be used for hanging, binding, or other similar applications.

[0033] The storage structure can be constructed in various forms, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the storage structure includes grooves 7 provided on both sides of the ramp plate 1 along its length, and the inverted U-shaped plate 2 has the same grooves 7 at corresponding positions. When the above scheme is adopted, the grooves 7 can be semi-circular grooves, so that when the ramp plate 1 is flipped, the grooves 7 of the ramp plate 1 and the grooves 7 of the inverted U-shaped plate 2 are aligned.

[0034] In some embodiments, the inverted U-shaped plate 2 can be constructed in various forms, and its structure is not uniquely limited. This embodiment optimizes and adopts one feasible option: the inverted U-shaped plate 2 includes a top plate 201 located at the top and side plates 202 located on both sides of the top plate 201. The top plate 201 and the side plates 202 are integrally formed and perpendicular to each other. When adopting the above solution, the width of the top plate 201 of the inverted U-shaped plate 2 can be equal to the height of the side plates 202.

[0035] The above are the embodiments listed in this example; however, this example is not limited to the optional embodiments described above; those skilled in the art can arbitrarily combine the above methods to obtain other various embodiments; anyone can derive other various forms of embodiments under the guidance of this example. The above specific embodiments should not be construed as limiting the scope of protection of this example; the scope of protection of this example should be determined by the claims.
