Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation, and in particular to a telescopic auxiliary platform and a flatbed transport vehicle. Background Technology

[0002] In the daily operation of hydropower stations, the transportation of production and living materials faces the "last mile" problem. In some special locations or narrow areas, trucks and pickups have difficulty entering, preventing the smooth delivery of materials. Flatbed trucks become the key to solving this problem, as they can move flexibly and ensure that materials successfully reach their destination.

[0003] Currently, the flatbed transport vehicles commonly found on the market have a relatively simple structure. Under normal circumstances, they can complete basic material transportation tasks and ensure the flow of daily production and living materials for hydropower stations. However, with the continuous development of hydropower stations and the gradual increase in operational requirements, the shortcomings of these traditional flatbed transport vehicles are becoming increasingly apparent, making it increasingly difficult to meet today's diverse and demanding material handling needs.

[0004] When handling large volumes of materials, traditional flatbed trucks often expand their carrying capacity by adding auxiliary platforms. However, this common practice of adding auxiliary platforms has a relatively fixed structure. Once installed, it's difficult to flexibly adjust the carrying capacity according to the actual size and quantity of the goods. This means that even with auxiliary platforms, they cannot perfectly adapt to various complex handling scenarios, resulting in less flexibility and convenience in the handling process and failing to fully realize their intended auxiliary role. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to provide a sub-vehicle plate that can flexibly change its load-bearing area according to actual usage needs.

[0006] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a telescopic sub-vehicle panel, which includes a storage panel;

[0007] The movable platform is embedded inside the storage platform and is set inside the storage platform by a sliding connection. The movable platform expands the load-bearing area of ​​the storage platform through telescopic movement.

[0008] The fastening sleeve assembly, located on the outer shell of the storage panel and the movable panel, is used to secure the extended position of the movable panel.

[0009] In a preferred embodiment of the telescopic sub-vehicle panel of this utility model: the outer shell of the storage vehicle panel is provided with two parallel sliding grooves, and a matching slider is installed on the outer side of the movable vehicle panel near the sliding grooves. The slider is slidably connected and disposed in the sliding grooves.

[0010] In a preferred embodiment of the telescopic auxiliary vehicle panel of this utility model: a support handle is provided at the end of the movable vehicle panel away from the storage vehicle panel, and a flip handle is provided on the side of the support handle away from the movable vehicle panel.

[0011] In a preferred embodiment of the telescopic sub-vehicle plate of this utility model: the fastening sleeve assembly includes a positioning hole opened on the outer shell of the storage vehicle plate, and a plurality of equidistant positioning threaded holes are opened on the movable vehicle plate. The positioning threaded holes are adapted to the positioning holes, and positioning bolts are inserted into the positioning holes and the positioning threaded holes.

[0012] In a preferred embodiment of the telescopic sub-cart plate of this utility model: the end of the positioning bolt for screwing is rotatably connected to a handle, and a magnetic suction piece is correspondingly provided on the outer shell of the storage cart plate near the handle.

[0013] In a preferred embodiment of the telescopic sub-cart plate of this utility model: a protective protrusion is installed around the outer shell of the storage cart plate along the throttle, and the protective protrusion is used for the side of sliding unloading and is set as a cutting surface with a certain slope.

[0014] The beneficial effects of this utility model are as follows: through the design of the sliding groove and the slider, the movable vehicle board can slide smoothly on the storage vehicle board. At the same time, positioning bolts are added to the storage vehicle board and the movable vehicle board to fix the two vehicle boards, so that the load-bearing area of ​​the telescopic sub-vehicle board can be adjusted according to the actual use needs.

[0015] In actual use, there is a problem that the added sub-platform cannot stably support the cargo.

[0016] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: a flatbed transporter includes a telescopic sub-platform and a vehicle body, which is rotatably connected to the storage platform via a hinge to expand the load-bearing area of ​​the vehicle body;

[0017] Support components, used to support the reinforced and deployed telescopic sub-platform;

[0018] The folding armrest, located at the rear end of the vehicle, is used to provide grip and support for the operator.

[0019] In a preferred embodiment of the flatbed transporter of the present invention: the support assembly includes several support grooves provided on the outer frame of the vehicle body. The outer frame of the vehicle body, except for the side with the folding handrail, is provided with several support grooves. Each support groove on each side is slidably connected with a suitable support component.

[0020] The support groove outlet end is provided with a limiting groove, the end of the support member inserted into the support groove is provided with a limiting block, and the support member is provided with a pull groove on the side away from the limiting block.

[0021] In a preferred embodiment of the flatbed transporter of this utility model: the folding handrail includes two detachable bases, which are arranged parallel to each other on the top of the vehicle body. The two bases are rotatably connected to a handrail. A slot is provided through the outer frame of the base. The two bases are movably connected to a lever through the corresponding slot. Both ends of the lever extend out of the outermost slot. A spring is provided on both sides of each base. The spring is used to elastically connect the protrusion on the outer side of the base and the lever.

[0022] In a preferred embodiment of the flatbed transporter of this utility model: the bottom of the vehicle body is provided with a plurality of omnidirectional wheels, and the omnidirectional wheels are provided with foot brakes.

[0023] The beneficial effects of this utility model are as follows: In actual operation, the support component is first pulled out from inside the vehicle body to ensure that it extends to the working position. Then, the telescopic sub-cargo board is placed on the extended support component. With its sturdy structure and reasonable layout, the support component provides a stable and reliable bearing foundation for the telescopic sub-cargo board, ensuring that there will be no shaking or deformation when carrying goods, thus effectively improving the safety and stability of the handling process.

[0031] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0032] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0033] Reference Figures 1-3 A telescopic sub-vehicle panel is provided, including a storage panel 1;

[0034] The movable platform 2 is embedded inside the storage platform 1 and is set inside the storage platform 1 in a sliding connection manner. The movable platform 2 expands the load-bearing area of ​​the storage platform 1 through telescopic movement.

[0035] The fastening sleeve assembly 3 is located on the outer shell of the storage plate 1 and the movable plate 2, and is used to fix the extended position of the movable plate 2.

[0036] Both the storage platform 1 and the movable platform 2 have different friction textures on their surfaces to increase the coefficient of friction, making the materials and items placed on the platforms more stable and preventing them from easily sliding and falling off, thus causing damage.

[0037] In use, the movable platform 2 is nested inside the storage platform 1. Under normal operating conditions, the movable platform 2 remains in a retracted state, not occupying extra space. When actual handling needs change and the load-bearing area of ​​the auxiliary platform needs to be increased, the operator first releases the locking state of the fastening sleeve assembly 3, then smoothly pulls out the movable platform 2, and precisely adjusts its position according to the specific size, quantity, and handling requirements of the goods. After the movable platform 2 reaches the appropriate position, the fastening sleeve assembly 3 is locked again to firmly fix the auxiliary platform with the adjusted load-bearing area, ensuring stable and reliable use in subsequent handling operations and meeting the handling needs in different scenarios.

[0038] Reference Figure 3 The outer shell of the storage vehicle plate 1 is provided with two parallel sliding grooves 11. The outer side of the movable vehicle plate 2 is equipped with a matching slider 21 near the sliding grooves 11. The slider 21 is set in the sliding grooves 11 in a sliding connection manner.

[0039] The slide groove 11 is formed on both sides of the storage plate 1, and the corresponding slider 21 is installed on the nested movable plate 2. The slider 21 is slightly smaller than or equal to the slide groove 11. Therefore, the slider 21 and the slide groove 11 can fit tightly together. When the movable plate 2 is extended or retracted, the slider 21 can slide smoothly along the slide groove 11, thereby accurately fixing the motion guide of the movable plate 2 and ensuring that the movable plate 2 can maintain stable and accurate movement during extension and retraction, thus improving the reliability and smoothness of the auxiliary plate when adjusting the load-bearing area.

[0040] Reference Figures 1-2 The movable platform 2 is provided with a support handle 22 at the end away from the storage platform 1, and the support handle 22 is provided with a flip handle 221 on the side away from the movable platform 2.

[0041] The support handle 22, located near the protective protrusion 34, is slightly higher than the outer shell of the storage panel 1, while the protective protrusion 34 is lower than the support handle 22. When the telescopic sub-panel is flipped onto the vehicle body 4 and not in use, the support handle 22 supports the telescopic sub-panel. Simultaneously, due to the height difference, the protective protrusion 34 does not press against the vehicle body 4, effectively preventing potential wear and damage and providing good protection. Furthermore, the flip handle 221 on the support handle 22 facilitates the operator's flipping of the telescopic sub-panel.

[0042] The side of the support handle 22 away from the protective protrusion 34 is at the same horizontal height as the outer shell of the storage platform 1. Therefore, when the telescopic sub-platform is flipped onto the vehicle body 4, one side of the telescopic sub-platform is flat. This ensures that the unevenness of the telescopic sub-platform will not affect the handling of goods during normal loading and unloading, thus guaranteeing the efficiency and safety of loading and unloading.

[0043] Reference Figures 1-3 The fastening sleeve assembly 3 includes a positioning hole 31 on the outer shell of the storage plate 1, and a number of equidistant positioning threaded holes 32 are provided on the movable plate 2. The positions of the positioning threaded holes 32 are adapted to the positioning holes 31, and positioning bolts 33 are inserted into the positioning holes 31 and the positioning threaded holes 32.

[0044] On the storage platform 1 and the movable platform 2, there are mutually compatible positioning holes 31 and positioning threaded holes 32 respectively. When it is necessary to adjust the bearing area of ​​the telescopic sub-platform, first slide the movable platform 2 to a suitable position so that the positioning holes 31 and positioning threaded holes 32 of the overlapping part of the two are precisely aligned, and then insert and screw the positioning bolts 33 into them.

[0045] In this way, the movable platform 2, which has been adjusted to its position, can be firmly fixed to the storage platform 1. This allows operators to flexibly adjust the load-bearing area of ​​the telescopic auxiliary platform according to the size and quantity of goods required in the actual usage scenario, meeting the handling requirements under different working conditions.

[0046] Reference Figures 1-3 The end of the positioning bolt 33, which is used for screwing, is rotatably connected to the handle 331. A magnetic suction piece is provided on the outer shell of the storage plate 1 near the handle 331.

[0047] The positioning bolt 33 and the throttle handle 331 are designed to be rotatably connected. When the operator needs to rotate or remove the positioning bolt 33, the throttle handle 331 can be rotated to a position perpendicular to the storage tray 1. This design makes the rotation operation easier and more convenient. After the positioning bolt 33 is installed, the throttle handle 331 is rotated to be parallel to the storage tray 1.

[0048] Furthermore, magnetic clasps are provided at the junction of the throttle handle 331 and the storage tray 1. When the throttle handle 331 is rotated to a parallel position, it will be attracted and placed in the storage groove inside the protective protrusion 34 by the magnetic clasps. At this time, the height of the throttle handle 331 is lower than that of the protective protrusion 34, and the protective protrusion 34 can effectively protect the throttle handle 331 during transportation, preventing it from being damaged.

[0049] Reference Figures 1-3 The outer shell of the storage vehicle plate 1 is equipped with a protective protrusion 34 around the throttle 331. The protective protrusion 34 is used for the side of sliding unloading and is set as a cutting surface with a certain slope.

[0050] The protective protrusion 34, through its internal storage groove and with the assistance of magnetic plates, securely houses the throttle 331, providing reliable protection against collisions or compression during transport. A gentle slope cutting surface is also designed on its outer edge, allowing goods to be unloaded smoothly from both sides of the protective protrusion 34 or from the cutting surface when the telescopic sub-panel is opened. In this way, while ensuring that the throttle 331 and positioning bolt 33 remain unaffected, normal unloading of goods is guaranteed, significantly improving loading and unloading efficiency.

[0051] Furthermore, the telescopic auxiliary platform can rotate more than 180 degrees, allowing it to be directly placed on the ground. When dealing with small but heavy goods, workers no longer need to use traditional handling methods; they can easily unload the goods by simply pushing them, reducing the difficulty of unloading.

[0052] Reference Figures 4-6A flatbed transporter is provided, including a telescopic sub-platform and a vehicle body 4, which is rotatably connected to a storage platform 1 via a hinge 41 to expand the load-bearing area of ​​the vehicle body 4.

[0053] Support component 5, which is used to support the reinforced and deployed telescopic sub-vehicle panel;

[0054] The folding armrest 6, located at the rear end of the vehicle body 4, is used to provide grip support for the operator.

[0055] In use, the telescopic sub-platform can be flexibly rotated using hinge 41, allowing it to smoothly unfold from the vehicle body 4. Next, the movable platform 2 is unfolded. Through this series of operations, the load-bearing area of ​​the vehicle body 4 is effectively expanded to meet the loading requirements of different goods. After completing the above steps, the support assembly 5 is pulled out from the inside of the vehicle body 4, and the unfolded telescopic sub-platform is placed on the support assembly 5, ensuring that the support assembly 5 provides stable support for the telescopic sub-platform, enabling it to bear cargo and ensuring the safety and stability of the cargo handling process.

[0056] In addition, the transport vehicle is equipped with a folding handrail 6. When the transport vehicle is not in use, the folding handrail 6 can be folded and stored, which effectively reduces the space occupied by the transport vehicle when it is stored, making it easier to store the transport vehicle when it is not in use and improving the space utilization of the transport vehicle.

[0057] Reference Figures 1-4 The support component 5 includes several support grooves 51 set on the outer frame of the vehicle body 4. Several support grooves 51 are opened on the outer frame of the vehicle body 4 except for the side of the folding armrest 6. Each support groove 51 is slidably connected to a suitable support component 52.

[0058] The support groove 51 has a limiting groove 511 at the outlet end, the support member 52 has a limiting block 521 at the end that is inserted into the support groove 51, and the support member 52 has a pull groove 522 on the side away from the limiting block 521.

[0059] The support grooves 51 are staggered in design to avoid interference between the support grooves 51 on the movement of the support member 52. A limiting groove 511 is provided at the groove opening of the support groove 51. The inner diameter of the limiting groove 511 is smaller than that of the support groove 51 and slightly smaller than or exactly equal to the insertion part of the support member 52 excluding the limiting block 521. At the same time, the two sides of the support groove 51 are provided with grooves specifically for accommodating the limiting block 521. These grooves are adapted to the limiting block 521.

[0060] Based on the above design, the support member 52 can slide stably within the support groove 51. When the telescopic sub-platform is placed on the support member 52, the support groove 51 provides a stable support foundation for the support member 52, ensuring the stability of the load. The limiting groove 511 and the limiting block 521 cooperate with each other to play a limiting protection role, so that the support member 52 will not be completely pulled out of the support groove 51 during the sliding process, avoiding safety hazards caused by the support member 52 falling off.

[0061] In addition, a groove 522 is provided on the non-insertion part of the support member 52, which makes it convenient for staff to use the support member 52. When it is necessary to pull out or retract the support member 52, the staff only needs to apply force through the groove 522 to complete the corresponding operation, which effectively improves the convenience and efficiency of the operation.

[0062] Reference Figures 5-6 The folding armrest 6 includes two detachable bases 61, which are parallel to each other on the top of the vehicle body 4. The armrest 62 is rotatably connected to both bases 61. The outer frame of the base 61 has a through slot 63. The two bases 61 are movably connected to a lever 64 through the corresponding slots 63. Both ends of the lever 64 extend out of the outermost slot 63. Each base 61 has a spring 65 on both sides. The spring 65 is used to elastically connect the protrusion on the outer side of the base 61 and the lever 64.

[0063] Both bases 61 are rotatably connected to the handle 62. In this structural design, the rotation of the handle 62 has a specific limiting mechanism. When the handle 62 attempts to rotate clockwise (or counterclockwise, depending on the actual operation), it will be blocked by the latch plate on the top of the base 61; if it attempts to rotate counterclockwise (or clockwise, depending on the actual operation), it will be stopped by the latch 64. The latch 64 is connected to the spring 65. Under natural conditions without external force, the latch 64 is pulled by the spring 65 and held in a certain position. At this time, the handle 62 can be fixed on the base 61, forming a state that is easy for workers to hold and push, facilitating the pushing operation of the transport vehicle.

[0064] When the folding handrail 6 needs to be folded, the operation method is reversed. The worker steps down on the locking lever 64. After the locking lever 64 is under force, it moves downward along the locking groove 63 until the locking lever 64 no longer blocks the handrail 62. At this time, the handrail 62, which is now freed from the restriction, can rotate counterclockwise (or clockwise, depending on the actual operation) to complete the folding operation smoothly, realizing the storage of the folding handrail 6 and reducing the space occupied by the transport vehicle when it is not in use.

[0065] Reference Figures 1-2 The bottom of the vehicle body 4 is equipped with several universal wheels 42, and foot brakes are installed on the universal wheels 42.

[0066] The foot brake on the pallet truck effectively counteracts the tendency of the pallet truck to slide due to gravity when the foot brake is activated, fixing the pallet truck in place and preventing it from sliding randomly during placement. This ensures the stability of the pallet truck when stationary and provides reliable safety for loading and unloading goods and parking the pallet truck.

[0067] In use, when it is necessary to expand the load-bearing area, firstly, the support member 52 is pulled out smoothly along the support groove 51 to ensure that the support member 52 is extended to the appropriate position. Then, the telescopic sub-carriage plate is flipped over on the extended support member 52 to provide a stable load-bearing base for the movable carriage plate 2. Next, the movable carriage plate 2 is slowly pulled out from the storage carriage plate 1. According to the actual size, quantity and other requirements of the goods, the position of the movable carriage plate 2 is adjusted. After the adjustment is in place, the movable carriage plate 2 is firmly fixed to the storage carriage plate 1 by the positioning bolts 33, so that the load-bearing area of ​​the sub-carriage plate can be flexibly adjusted to meet diverse handling needs.

[0068] For unloading goods that are small in size but heavy in weight, the heavy items can be placed on the vehicle body 4 first. During the unloading phase, the support component 52 is first inserted back into the vehicle body 4 along its original path to complete the storage. Then, the telescopic auxiliary platform is flipped downwards, so that one end rests stably on the ground, forming a convenient slide. With the help of this slide, workers can easily slide the heavy items down the slide, greatly reducing the difficulty of unloading, improving unloading efficiency, and ensuring the safety and efficiency of cargo unloading.

[0069] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
