Detailed Implementation

[0016] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] Example 1 Please see Figures 1 to 6The present invention preferably provides the following technical solution: a transport frame assembly, comprising: a first cantilever frame; a second cantilever frame that is retractably installed with the first cantilever frame; a hook assembly provided on the second cantilever frame for transfer and suspension during cargo transport; and lifting outriggers respectively provided at opposite ends of the first and second cantilever frames for forming stable support on the ground; and auxiliary outriggers respectively provided on both sides of the first and second cantilever frames for assembly with a vehicle body 111 for transporting goods; when the lifting outriggers are in contact with the ground, they are used for loading and unloading goods; when the lifting outriggers and auxiliary outriggers are assembled with the vehicle body 111, a transport frame assembled with the vehicle body 111 can be formed.

[0018] This embodiment combines a convertible support system (lifting outriggers and auxiliary outriggers) with a retractable main structure (first and second cantilever beams) to design a device that combines on-site loading and unloading with transportation in transit, solving the pain points of single device function, cumbersome process and low efficiency in traditional cargo transfer. Specifically, such as Figure 1 , 2 As shown in Figures 4, 5, and 6, the lifting outriggers mounted on opposite ends of the first and second suspension beams can form a stable support with the ground, and the auxiliary outriggers mounted on both sides can be assembled with the vehicle body 111 for transporting goods. The collaborative design of the lifting outriggers and auxiliary outriggers in this application is the core of the device, and it can be implemented in various ways to meet multiple loading and unloading needs of goods. The first implementation method: The lifting outriggers are supported on the ground and can be used to unload goods directly from the transport vehicle. By assembling the auxiliary outriggers with the vehicle body 111, they can also be transported as part of the goods. This integrates the functions of "on-site lifting device" and "transport load-bearing frame". There is no need to call additional cranes or hoists at the loading and unloading site, nor is it necessary to transfer goods from one load-bearing frame to another. One set of devices can complete the entire process from "unloading" to "transfer" to "loading", which greatly simplifies the operation process. The second implementation method: When the lifting outriggers are supported on the ground and the auxiliary outriggers are detached from the vehicle body 111, the transport frame assembly can be supported independently so that multiple vehicle bodies 111 can be loaded and unloaded at a certain position. The transport frame assembly in this implementation method can replace large lifting devices and is suitable for field operation sites without fixed lifting devices, temporary construction sites and transfer stations with inadequate storage facilities. The above two implementation methods: First, it significantly improves loading and unloading efficiency, saves time waiting for and scheduling large lifting equipment, reduces loading and unloading operations and manpower requirements. The simplification of the operation process directly translates into time cost savings and improved turnover efficiency, thereby reducing the overall logistics operation cost. Secondly, it achieves functional integration and multi-purpose functionality. The lifting outriggers provide a stable support base independent of the vehicle body 111, ensuring the stability and safety of loading and unloading operations. The auxiliary outriggers enable a quick and reliable connection between the device and the vehicle body 111. This design allows the device to switch quickly and flexibly between "operation mode" and "transportation mode". Furthermore, the pull-out installation structure of the first and second suspension beams allows the span of the entire suspension mechanism to be adjusted; Finally, the simplified operating procedures reduce the reliance on professional crane operators, and ordinary freight workers can complete most of the operations after simple training, which alleviates the human resource pressure of specific jobs. In summary, this application creatively integrates the functions of "lifting" and "transportation" by designing its functions in an integrated and structurally convertible manner, achieving the effect of functional integration and multi-purpose use of one machine. This not only greatly improves loading and unloading efficiency and expands application scenarios, but also simplifies the operation process and optimizes the allocation of human resources.

[0019] Furthermore, the first suspension beam includes two symmetrically distributed slide rails 116; and a connecting plate 128 fixed to one end of the two slide rails 116, wherein the connecting plate 128 and the two slide rails 116 can together form an inverted frame; the second suspension beam includes a sliding plate 117 that is pulled out and installed inside the two slide rails 116 and can move outward through the opening where the inverted frame is located.

[0020] like Figure 1 As shown, the connecting plate 128 where the first cantilever frame is located and the two slide rails 116 can form an inverted frame, while the sliding plate 117 of the second cantilever frame is housed in the two slide rails 116 and can move outward through the opening where the inverted frame is located, realizing the pull-out design. This design is adaptable to goods of different sizes: the support points can be flexibly adjusted according to the length or width of the goods; On the other hand, it adapts to different working spaces: it can retract in narrow spaces to facilitate passage, and it can extend in open areas to provide a larger lifting coverage area; Other advantages include ease of transport and storage: When not in operation, the retractable structure reduces space requirements, facilitating storage and transport on the vehicle.

[0021] Furthermore, a meshing drive assembly is provided between the first and second suspension beams for driving the second suspension beam to move relative to the first suspension beam. The meshing drive assembly includes an assembly frame 125 fixed on one of the slide rails 116, a first motor 126 on the assembly frame 125, the output end of the first motor 126 passing downward through a first through hole in the assembly frame 125 and fixed with a gear 127; and a rack 124 fixed on the slide plate 117, and the rack 124 meshes with the gear 127.

[0022] like Figure 1 , 2 As shown, since gear 127 is connected to slide rail 116 and rack 124 is fixed on slide plate 117, slide plate 117 can be translated relative to slide rail 116 through the meshing gear 127 and first motor 126.

[0023] Furthermore, the hook assembly includes a through groove 118 formed on the slide plate 117, with side plates 119 fixed on the slide plate 117 on both sides of the through groove 118; and a roller 120 rotatably mounted opposite to the two side plates 119, with a plurality of steel ropes 121 fixed on the roller 120, the bottom ends of the steel ropes 121 facing downward and fixed with hooks 122; it also includes a second motor 123 disposed on the side wall of one of the side plates 119, and the output end of the second motor 123 passes through a second through hole formed on the side wall of one of the side plates 119 and is fixed to the roller 120.

[0024] like Figure 1 , 2 As shown, the slide plate 117 is fixed with side plates 119 on both sides of the through groove 118. The roller 120 is rotatably mounted on the two side plates 119. Several steel ropes 121 fixed on the roller can pass downward through the through groove 118 and are fixed with hooks 122. With the help of the second motor 123 connected to the roller 120, when it is necessary to load or unload goods, the hooks 122 are first hooked out of the goods. Then, when the second motor 123 runs, the winding or unwinding steel ropes 121 can move the goods up or down. With the lateral translation of the slide plate 117, the process of transferring goods from the ground to the vehicle body 111 or unloading goods from the vehicle body 111 can be realized.

[0025] Furthermore, each lifting outrigger includes a vertical plate 129, with a plurality of first electric telescopic rods 130 disposed at the bottom of the vertical plate 129; and a roller 132 installed at the telescopic end of each first electric telescopic rod 130.

[0026] like Figure 1 , 2 As shown in Figures 4, 5, and 6, when loading and unloading goods are required, the first electric telescopic rod 130 can be extended and retracted adaptively to enable the roller 132 to support the ground or detach from the ground, thereby allowing the device to switch quickly and flexibly between the "operation mode" and the "transportation mode".

[0027] Furthermore, each auxiliary support leg includes a crossbeam 112 fixedly connected to the corresponding slide rail 116, and a second electric telescopic rod 113 installed at both ends of the crossbeam 112, with a plug 114 fixed to the telescopic end of the second electric telescopic rod 113.

[0028] like Figure 2 , 4As shown in Figure 5, the crossbeam 112 is fixed to the slide rail 116, and the output ends of the second electric telescopic rods 113 set at both ends of the crossbeam 112 are fixed with insert blocks 114. The insert blocks 114 are connected to the insert frames 115 set on the vehicle body 111. When the transport frame assembly needs to be transported with the vehicle body 111 or when it needs to be reinforced during loading and unloading, the insert blocks 114 and insert frames 115 can be connected.

[0029] Furthermore, a control panel 131 is provided on the outer wall of one of the vertical plates 129 for adjusting the various drive structures.

[0030] Control panel 131 here Figure 2 As shown, it is an existing mature technology and can be used for independent control of the drive structure in the meshing drive assembly, lifting outriggers, and auxiliary outriggers.

[0031] Example 2 As another embodiment of the present utility model, a road transport vehicle includes a vehicle body and the aforementioned transport frame assembly: wherein the transport frame assembly can be assembled on the vehicle body 111 to form a transport frame assembled with the vehicle body 111; a transverse groove 133 is provided in the middle of the vehicle body 111, and an insert plate 134 is provided in the transverse groove 133; and a vertical groove 135 is provided on one side of the vehicle body 111 and communicates with the transverse groove 133 in a T-shape, and a stop plate 136 is provided in the vertical groove 135, the middle part of which is fixed to the end of the insert plate 134, and both ends of which are connected to the inner wall of the vertical groove 135 by springs 137; It also includes a stop block 138 disposed on the inner wall of the vertical plate 129 where each lifting outrigger is located, wherein the side wall of the stop block 138 away from the stop plate 136 is provided with a slot 139 for insertion and installation with the insert plate 134; and an insert frame 115 installed on the side wall of the vehicle body 111, wherein the insert frame 115 is adapted to be inserted and connected with the insert block 114.

[0032] like Figure 1 As shown, two auxiliary outriggers and two lifting outriggers are respectively placed on both sides and both ends of the first and second suspension beams. Since the vehicle body 111 can extend under the first and second suspension beams and can be placed inside the lifting outriggers and auxiliary outriggers, when loading and unloading goods, the lifting outriggers can support the ground, and when it is necessary to transport goods with the vehicle, the auxiliary outriggers can be assembled with the vehicle body 111, while the lifting outriggers retract. In addition, considering the safety of the transport frame assembly during transport with the vehicle body 111, this application fixes abutments 138 on opposite sides of the vertical plates 129 of the two lifting legs. The insert plate 134 installed in the middle of the vehicle body 111 has one end that can extend into the vertical groove 135 and be fixed to the middle of the abutment plate 136, and the other end that can extend into the slot 139. Therefore, when the lifting leg near the abutment plate 136 moves closer to the vehicle body 111, the abutment block 138 of the lifting leg near the abutment plate 136 can abut against the abutment plate 136 and compress the spring 137 and the pressurized insert plate 134. Then the insert plate 134 extends into the slot 139 of the other lifting leg, realizing the switching of the transport state.
