Description

Technical Field

[0001] This utility model relates to the field of transport vehicle technology, and in particular to a new energy bidirectional transport vehicle. Background Technology

[0002] In the field of bridge construction, the efficiency of transporting prefabricated components (such as box girders, bridge decks, and steel trusses) directly affects the project's progress and safety. These large prefabricated components are mostly transported by trucks.

[0003] However, traditional transport vehicles have the following key drawbacks: First, they have limited turning space. Due to the narrow environment of bridge construction sites (such as approach bridges and elevated walkways), traditional single-head transport vehicles need a large turning radius to turn around, which can easily lead to collision risks or delays in the construction period. Second, they have low loading and unloading efficiency. The loading of prefabricated components (especially small auxiliary parts) relies entirely on cranes to lift them to the top of the vehicle frame, resulting in insufficient high-altitude docking accuracy and a high proportion of time spent on each loading and unloading operation.

[0004] In summary, traditional transport vehicles suffer from problems such as limited turning space and low loading and unloading efficiency. Utility Model Content

[0042] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0043] In the field of bridge construction, the efficiency of transporting prefabricated components (such as box girders, bridge decks, and steel trusses) directly affects the project's progress and safety. These large prefabricated components are mostly transported by trucks.

[0044] However, traditional transport vehicles have the following key drawbacks: First, limited turning space. Due to the narrow environment of bridge construction sites (such as approach bridges and elevated walkways), traditional single-head transport vehicles need a large turning radius to complete the turn, which can easily lead to collision risks or delays in the construction period. Second, low loading and unloading efficiency. The loading of prefabricated components (especially small auxiliary parts) relies entirely on cranes to lift them to the top of the vehicle frame, resulting in insufficient high-altitude docking accuracy and a high proportion of time spent on each loading and unloading. Third, dynamic balance hazards. Due to the concentrated load on one side during component loading and unloading, the vehicle frame may twist and deform.

[0045] In summary, traditional transport vehicles suffer from problems such as limited turning space, low loading and unloading efficiency, and potential dynamic balance issues.

[0046] like Figures 1 to 10 As shown, this utility model provides a new energy bidirectional transport vehicle, including a frame 1 and a first front end 2 and a second front end 3 disposed at both ends of the frame 1;

[0047] The first cab 2 and the second cab 3 are arranged symmetrically about the top center of the frame 1, and the first cab 2 and the second cab 3 travel in opposite directions. Specifically, the first cab 2 and the second cab 3 are both composed of a cab and two wheels located below the cab. The cab is located on the top of the frame 1, and the two wheels are located at the bottom of the frame 1. Specifically, the two wheels are connected by a pivot. The cab door of the first cab 2 is located at the rear of the cab, and the cab door of the second cab 3 is located at the front of the cab.

[0048] This bidirectional transport vehicle is equipped with bidirectional cabs, eliminating blind spots and making it suitable for use in narrow construction environments. In addition, the dual cab configuration, with a driver's cab on each cab, enables bidirectional travel. The centrally symmetrical dual cab layout conforms to the principles of mechanical dynamics and ensures balanced front and rear weight distribution.

[0049] The bottom of the frame 1 is provided with mounting parts 13 at the positions corresponding to the first front end 2 and the second front end 3. The bottom of the mounting parts 13 is provided with a transfer part 14. The transfer part 14 includes a first transfer frame 4 and a second transfer frame 5 connected to each other. The first transfer frame 4 extends along the width direction of the frame 1, and the second transfer frame 5 extends along the length direction of the frame 1.

[0050] Specifically, such as Figure 1-3 As shown, in this new energy bidirectional transport vehicle, taking the first vehicle head 2 located at the bottom right end of the frame 1 as an example, the mounting part 13 is fixedly installed at the bottom of the frame 1 at the position corresponding to the first vehicle head 2, and the transfer part 14 is fixedly installed at the bottom of the mounting part 13. The transfer part 14 includes a first transfer frame 4 and a second transfer frame 5 connected to each other, and the first transfer frame 4 extends along the length direction of the frame 1, and the second transfer frame 5 extends along the width direction of the frame 1.

[0051] The first transfer frame 4 extends along the width direction of the frame 1, meaning that the length direction of the first transfer frame 4 is parallel to the width direction of the frame 1.

[0052] The second transfer frame 5 extends along the width direction of the frame 1, meaning that the length direction of the second transfer frame 5 is parallel to the length direction of the frame 1.

[0053] like Figures 1 to 8 As shown, in some embodiments of this utility model, the frame 1 of the new energy bidirectional transport vehicle can adopt a high-strength steel-aluminum composite frame, and its first front 2 and second front 3 can adopt a standardized detachable cabin. Its running mechanism adopts four-wheel independent steering + geared motor drive. In addition, the power system of the new energy bidirectional transport vehicle adopts a new energy power system, that is, it adopts a lithium iron phosphate battery pack integrated into the bottom platform of the frame 1.

[0054] The first cab 2 and the second cab 3 are both composed of a cab and two wheels located below the cab. The cab is located on the top of the frame 1, and the two wheels are located at the bottom of the frame 1. Specifically, the two wheels are connected by a shaft.

[0055] Specifically, the bidirectional transportation of this new energy bidirectional transport vehicle can be carried out based on the following process: the first vehicle head 2 and the second vehicle head 3 are located at the right end and left end of the frame 1, respectively. The direction of the first vehicle head 2 moving to the right is marked as the forward direction of the first vehicle head 2, and the direction of the second vehicle head 3 moving to the left is marked as the forward direction of the second vehicle head 3. When the second vehicle head 3 moves forward, the geared motor rotates in the forward direction, driving the shaft on the second vehicle head 3 to rotate, which in turn drives the drive wheel on the second vehicle head 3 to rotate, thereby driving the transport vehicle to move forward along the forward direction of the second vehicle head 3. When the first vehicle head 2 moves forward, the geared motor is controlled to rotate in the reverse direction, which drives the entire transport vehicle to move forward along the forward direction of the first vehicle head 2. Specifically, this drive technology has been maturely applied in new energy engineering vehicles in China, and will not be elaborated here.

[0056] like Figures 1 to 8 As shown, in some embodiments of this utility model, the side of the frame 1 is provided with a plurality of mounting ears 11; the mounting ears 11 are provided for hoisting the new energy bidirectional transport vehicle with a suspension device, so as to facilitate the transfer of the new energy bidirectional transport vehicle.

[0057] like Figures 1 to 8 As shown, in some embodiments of this utility model, the bottom of the frame 1 is provided with multiple reinforcing ribs;

[0058] Multiple reinforcing ribs are arranged in a linear array along the length of the frame 1;

[0059] Since the frame 1 has a smooth plate surface and is relatively long, the design of multiple reinforcing ribs helps to improve the strength of the frame 1 and enhance its resistance to deformation.

[0060] like Figures 1 to 8 As shown, in some embodiments of this utility model, a protective partition 12 is provided at the top of the frame 1 near the first front end 2 and the second front end 3.

[0061] A protective partition 12 is provided to isolate the cab from the cargo storage area on top of the frame 1, effectively protecting the cab.

[0062] like Figures 1 to 8 As shown, in some embodiments of this utility model, the first transfer frame 4 and the second transfer frame 5 have the same structure.

[0063] The first transfer frame 4 includes a U-shaped storage plate 6 and a transfer plate 7 disposed in the open end of the U-shaped storage plate 6. The U-shaped storage plate 6 includes a base plate 61 and side plates 62 disposed at both ends of the base plate. Both side plates 62 are perpendicular to the base plate 61.

[0064] A top pressure plate 63 is provided at one end of the side plate 62 away from the bottom plate 61, and the width of the top pressure plate 63 is greater than the width of the side plate 62.

[0065] The side of the edge plate 62 is provided with a sliding groove 64 along the length direction. The side of the transfer plate 7 that contacts the edge plate 62 is provided with a sliding column 71, which is slidably disposed in the sliding groove 64.

[0066] The rear end of the side plate 62 is provided with an extension ear plate 65, and the right side of the extension ear plate 65 is provided with an extension groove 66 that communicates with the sliding long groove 64.

[0067] The method of using this transfer rack is as follows:

[0068] The transfer plate 7 is pulled out from the U-shaped storage plate 6, and the sliding column 71 is slid along the sliding groove 64 until the sliding column 71 is located in the extension groove 66. The transfer plate 7 is then lowered, so that one end of the transfer plate 7 is limited to the rear end of the U-shaped storage plate 6 due to the cooperation of the sliding column 71 and the extension groove 66, and the other end of the transfer plate 7 is placed on the ground. This makes the transfer plate 7 arranged in an inclined position, forming a transfer channel with a certain slope, so that goods can be transported through the transfer plate 7.

[0069] In addition, the transfer rack located under the front of the vehicle can assist the driver in entering the cab;

[0070] The use of the first transfer frame 4 and the second transfer frame 5 has the following advantages:

[0071] First, the transfer channel can be quickly constructed by simply pulling out the transfer plate 7 and sliding it along a preset path (sliding groove 64) until it is finally positioned (extension groove 66). The operation is intuitive and simple, requiring no complicated installation or additional tools.

[0072] Secondly, the precise fit between the sliding column 71 and the extension groove 66 securely limits one end of the transfer plate 7 to the rear end of the U-shaped storage plate 6, while the other end of the transfer plate 7 is stably placed on the ground. This double fixing method ensures that the transfer plate 7 forms a stable and reliable inclined structure with a fixed slope that is not easy to slide or shift.

[0073] Third, the resulting inclined ramp (transfer channel) is a core advantage. It allows goods (especially wheeled trolleys, pallets, or heavy items) to smoothly slide or push from a higher position (such as near the U-shaped storage panel 6) to a lower position (the ground) using gravity or with only slight pushing force. This significantly reduces the intensity of manual handling, especially for heavier or larger goods, avoiding strenuous manual lifting or horizontal dragging. It also improves handling efficiency and speeds up the loading, unloading, or transfer of goods.

[0074] Fourth, the transfer plate 7 can be completely stored inside the U-shaped storage plate 6 when not in use, greatly saving storage space and featuring a compact structure. It can be quickly unfolded and used when needed, demonstrating excellent portability and ease of use.

[0075] Fifth, the design of the sliding column 71 moving along the sliding groove 64 provides a clear movement trajectory and guidance, ensuring that the transfer plate 7 is stable and smooth during extraction and positioning, and is not prone to deviation or jamming. Specifically, since the first transfer frame 4 extends along the width direction of the frame 1 and the second transfer frame 5 extends along the length direction of the frame 1, and the first transfer frame 4 is located directly below the front of the vehicle, in actual installation, it is necessary to ensure that when the transfer plate 7 on the first transfer frame 4 is extracted, the transfer plate 7 is located on the side of the corresponding front of the vehicle, that is, on the cab of the corresponding front of the vehicle, near the door. When the cab door is opened, the extracted transfer plate 7 can assist the driver to enter the cab, and can also serve as a ramp to assist the driver to leave the cab. In addition, the second transfer frame 5 extends along the length direction of the frame 1, and the second transfer frame 5 is located to the side of the first transfer frame 4. In actual installation, it is necessary to ensure that when the transfer plate 7 on the second transfer frame 5 is extracted, the transfer plate 7 is located to the side of the frame 1.

[0076] Specifically, the first transfer frame 4 located at the bottom of the first car head 2 is marked as the 1# car head transfer frame, and the second transfer frame 5 located on the side of the 1# car head transfer frame is marked as the 1# cargo transfer frame; when the transfer plate 7 on the 1# car head transfer frame is pulled out, it is located at the rear end of the car frame 1; when the transfer plate 7 on the 1# cargo transfer frame is pulled out, it is located at the right end of the car frame 1.

[0077] The first transfer frame 4 located at the bottom of the second car head 3 is marked as the 2# car head transfer frame, and the second transfer frame 5 located on the side of the 2# car head transfer frame is marked as the 2# cargo transfer frame; when the transfer plate 7 on the 2# car head transfer frame is pulled out, it is located at the front end of the frame 1; when the transfer plate 7 on the 2# cargo transfer frame is pulled out, it is located at the left end of the frame 1.

[0078] like Figures 1 to 8 As shown, in some embodiments of this utility model, the top of the transfer plate 7 is provided with an anti-slip layer;

[0079] It is equipped with an anti-slip layer to prevent goods from slipping during transportation.

[0080] like Figures 1 to 8 As shown, in some embodiments of this utility model, the top pressure plate 63 extends into the inner side of the U-shaped storage plate 6.

[0081] The top pressure plate 63 extends inward to the U-shaped storage plate 6, thereby limiting the top of the transfer plate 7.

[0082] like Figures 1 to 8 As shown, in some embodiments of this utility model, the top of the transfer plate 7 is provided with a pad 72, and the top of the pad 72 is fixedly connected to the bottom of the top pressure plate 63.

[0083] A pad 72 is provided to limit the top of the transfer plate 7 and prevent the transfer plate 7 from shaking when placed inside the opening of the U-shaped storage plate 6.

[0084] like Figures 1 to 8 As shown, in some embodiments of this utility model, the base plate 61 is also provided with a transfer plate pressing mechanism 8.

[0085] The transfer plate clamping mechanism 8 includes a clamping block 81, a connecting rod 82, and a pulling block 83 connected sequentially from top to bottom. One end of the connecting rod 82 is fixedly connected to the clamping block 81, and the other end of the connecting rod 82 is fixedly connected to the pulling block 83.

[0086] A mounting sliding hole 67 is provided at the bottom of the base plate 61 corresponding to the position of the connecting rod 82. The connecting rod 82 is located in the mounting sliding hole 67. A storage groove 68 is provided at the top of the base plate 61 corresponding to the position of the mounting sliding hole 67, which cooperates with the clamping block 81. The inner diameter of the storage groove 68 is adapted to the outer diameter of the clamping block 81. The inner diameter of the storage groove 68 is larger than the inner diameter of the mounting sliding hole 67, and the storage groove 68 is connected to the mounting sliding hole 67.

[0087] A spring 84 is fitted on the outside of the connecting rod 82, and the two ends of the spring 84 are respectively connected to the clamping block 81 and the pulling block 83;

[0088] The clamping block 81 is made of an elastic material;

[0089] The transfer plate clamping mechanism 8 has a clamping block 81 located between the transfer plate 7 and the base plate 61, and a pulling block 83 located at the bottom of the base plate 61.

[0090] In actual use, in the initial state, due to the presence of spring 84, the top of the clamping block 81 is pressed tightly against the bottom of the transfer plate 7 under the action of spring 84, thereby fixing the transfer plate 7 between the pad 72 and the clamping block 81, preventing the transfer plate 7 from sliding out of the opening end of the U-shaped storage plate 6 when not in use; when in use, that is, when it is necessary to pull the transfer plate 7 out of the opening end of the U-shaped storage plate 6, the clamping block 81 can be pulled into the storage slot 68 by pulling block 83, thereby releasing the clamping state of the transfer plate 7, so that the transfer plate 7 can be easily pulled out from the opening end of the U-shaped storage plate 6.

[0091] This utility model provides a new energy bidirectional transport vehicle, which adopts a dual-head configuration and the head is strictly symmetrical about the center of the top of the frame, ensuring that the frame is evenly distributed when traveling in any direction, eliminating the risk of center of gravity shift on bridge curves and sloping road sections.

[0092] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
