Description

Technical Field

[0001] The present invention relates to the technical field of modular electric drive road train combination structures, and particularly to a modular electric drive road train combination structure. Background Art

[0002] Traditional road trains (also known as road trailers or road freight trains) usually consist of a tractor head and multiple trailers. In recent years, the concept of modular design has been widely applied in many fields. Modular design can not only improve the flexibility and scalability of the system, but also reduce production costs and maintenance difficulties. In the field of road transportation, modular design can achieve free combination between different modules to meet different transportation needs. However, traditional road freight vehicles have problems such as large self-weight, high energy consumption, and low transportation efficiency.

[0003] In addition, the following problems exist in traditional road transportation vehicles and need to be solved urgently. The modular degree of road freight vehicles is low, the marshalling flexibility is poor, and it is difficult to adapt to the needs of multimodal transport. At the same time, the standardization degree of freight vehicles is low, and the land and sea transportation standards are not unified, resulting in frequent unpacking, packing, and container changing operations. When the trailer with a container is docked with the frame of the tractor head, relevant tools are required for multi-directional disassembly and assembly, which takes a long time during the disassembly and assembly process, increasing the logistics cost and time cost. Therefore, a modular electric drive road train combination structure is needed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: A modular electric drive road train combination structure includes a tractor head. At the center position of the top end of the tractor head, a trailer assembly is docked through a fixing component. The trailer assembly consists of a frame and a carriage. At the side of the top end of the tractor head, a lifting component is provided. The frame can be temporarily supported through the lifting component, which is convenient for adjusting the height on the left side of the frame and improving the adaptability adjustment effect of the frame. The fixing component includes a clamping plate. A hook column is inserted into the clamping plate through a card slot at the top end of the clamping plate, and the top end of the hook column is fixedly connected to the bottom end of the frame. A reinforcing fitting is movably arranged on the left side of the card slot of the clamping plate. The opening end of the card slot of the clamping plate and the hook column are on the same vertical horizontal line, which is convenient for clamping with the hook column. The hook column can be locked and reinforced through the reinforcing fitting. Adjusting components are arranged on both sides of the frame. The adjusting component includes a steel cylinder welded to the bottom end of the frame. A movable square shaft is inserted into the steel cylinder. An auxiliary support fitting is movably installed on the side of the movable square shaft. The movable square shaft can be pulled in and out of the steel cylinder, enabling the auxiliary support fitting to displace, and then adapting to the truck bed end of the tractor head with different widths.

[0006] Preferably, an L-shaped support plate end is provided on the side of the bottom end of the vehicle frame, and the auxiliary support fitting is placed inside the L-shaped support plate end. Under normal conditions, the support shaft is parallel to the bottom end of the vehicle frame, and the support shaft can be retracted into the L-shaped support plate end at the bottom end of the vehicle frame to ensure the retraction and extension effect of the support shaft.

[0007] Preferably, the auxiliary support fitting includes a support shaft. The top end of the support shaft is movably docked with the side of the movable square shaft. The bottom end of the support shaft is inserted with an inner insertion shaft through a through hole. The bottom end of the inner insertion shaft is connected with a support leg. By moving the inner insertion shaft downward in the support shaft, the height of the vehicle frame can be adapted.

[0008] Preferably, a locking bolt is inserted through a threaded hole on the side of the bottom end of the support shaft, and the shaft end of the locking bolt is inserted into the positioning hole of the inner insertion shaft. By passing the locking bolt through the support shaft and inserting it into the positioning hole of the inner insertion shaft, the stability of the inner insertion shaft after adjustment is ensured.

[0009] Preferably, a first insertion shaft is inserted through a through hole on the surface of the steel cylinder. A plurality of positioning holes are equidistantly arranged on the surface of the movable square shaft. When the adjustment of the auxiliary support fitting is completed, the first insertion shaft can be passed through the steel cylinder and inserted into the positioning hole of the movable square shaft, thereby ensuring the stability of the movable square shaft after installation.

[0010] Preferably, a positioning seat is connected to the bottom end of the steel cylinder. A second insertion shaft is horizontally inserted through a through hole on the side of the support shaft. By passing the second insertion shaft through the support shaft and inserting it into the positioning hole of the positioning seat, the support shaft is vertically fixed.

[0011] Preferably, the lifting assembly includes two bottom frames fixed to the side of the hopper end of the tractor head. A first hydraulic cylinder is installed in each of the two bottom frames. The top end of the piston rod of the first hydraulic cylinder is connected with a support plate. The two support plates are butt-jointed and fixed through a connecting plate. A rubber pad is arranged at the top end of the support plate. By the telescopic movement of the piston rod end of the first hydraulic cylinder, the support plate can be controlled to temporarily lift the vehicle frame, thereby facilitating the adjustment of the vehicle frame. When the support plate supports the vehicle frame, the rubber pad at the top end of the support plate can reduce the wear degree on the vehicle frame during support. Preferably, two positioning columns are symmetrically connected to the left and right sides of the bottom end of the clamping plate, and the positioning columns are inserted into the inside of the fixed seat through through grooves. The bottom end of the fixed seat is fixed on the surface of the hopper end of the tractor head. A second hydraulic cylinder is installed on the right side of the bottom end of the clamping plate, and the cylinder seat end of the second hydraulic cylinder is fixed on the surface of the hopper end of the tractor head. By the telescopic movement of the piston rod end of the second hydraulic cylinder, the height of the clamping plate can be controlled and adjusted, facilitating the docking of the clamping plate with the hook column during up and down movement. When the clamping plate moves, the through groove of the fixed seat can limit and guide the positioning column to ensure the stability of the up and down movement of the clamping plate and avoid affecting the vertical telescopic movement of the piston rod end.

[0012] Preferably, a vane end is provided at the bottom end of the clamping plate. The reinforcement fitting includes a fixed stopper, and the fixed stopper is movably installed inside the card slot of the clamping plate. A chute adapted to the clamping plate is opened on the side of the fixed stopper. A side plate is connected to the side of the fixed stopper, and a third hydraulic cylinder is installed on the right side of the side plate. The third hydraulic cylinder is installed on the bottom surface of the clamping plate. A limit groove adapted to the hook column is opened inside the fixed stopper to further lock and fix the hook column. When the fixed stopper moves, the fixed stopper can further reinforce the hook column. The hook column is composed of a column end and a disc end structure. During the clamping process, the disc end of the hook column can cooperate with the card slot of the clamping plate to ensure the docking stability between the hook column and the clamping plate.

[0013] The present invention has at least the following beneficial effects: 1. By setting the fixing component, compared with the traditional structure, in this device, the hook column is inserted into the square slot of the card slot of the clamping plate and moves, so that the inner chute of the card slot of the clamping plate can move on the surface of the hook column, thereby realizing the docking and fixing of the clamping plate and the hook column, ensuring the quick docking of the tractor head and the vehicle frame, improving the marshalling flexibility, thus adapting to the needs of multimodal transport, facilitating the relevant staff to quickly disassemble and assemble the vehicle frame. The tractor head and the vehicle frame can be freely disassembled and combined to realize the heavy box and empty box swap hanging transportation, and the single vehicle operation efficiency is increased by 30%.

[0014] 2. By setting the reinforcement fitting, the reinforcement of the hook column and the clamping plate is realized. In this device, the fixed stopper moves on the surface of the plate end of the clamping plate, and the fixed stopper can be controlled to be buckled on one side of the hook column to prevent the hook column from disengaging from the card slot of the clamping plate, thereby improving the reinforcement between the hook column and the clamping plate.

[0015] 3. By setting, the suspension support on the left side of the vehicle frame is realized. In this device, the inner insertion shaft is pulled in and out of the support shaft, and the support feet can be controlled to support on the ground surface, so as to adapt and adjust the ground clearance of the vehicle frame, facilitate the movement of the bucket end of the tractor head in and out under the vehicle frame, quickly adjust the adaptability between the hook column and the card slot of the clamping plate, realize the quick docking of the bucket end of the tractor head and the vehicle frame, and effectively reduce the logistics cost and time cost.

Detailed implementation manners

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Refer to Figure 1-7 , a modular electric drive road train combined structure, including a tractor head 1, the center position at the top of the tractor head 1 is docked with a trailer assembly 2 through a fixing component 6, the trailer assembly 2 is composed of a vehicle frame 21 and a carriage 22, and a lifting component 4 is arranged on the side of the top of the tractor head 1. The vehicle frame 21 can be temporarily supported by the lifting component 4, which is convenient for adjusting the height on the left side of the vehicle frame 21 and improving the adaptation and adjustment effect of the vehicle frame 21; The fixing component 6 includes a clamping plate 63. The top of the clamping plate 63 is inserted with a hanging column 5 through a clamping groove, and the top of the hanging column 5 is fixedly connected to the bottom end of the vehicle frame 21. A reinforcing fitting 65 is movably arranged on the left side of the clamping groove of the clamping plate 63; Adjusting components 3 are arranged on both sides of the vehicle frame 21. The adjusting component 3 includes a steel cylinder 31 welded to the bottom end of the vehicle frame 21. An active square shaft 32 is inserted into the steel cylinder 31, and a supporting fitting 34 is movably installed on the side of the active square shaft 32.

[0021] An L-shaped support plate end is arranged on the side of the bottom end of the vehicle frame 21, and the supporting fitting 34 is placed inside the L-shaped support plate end.

[0022] The supporting fitting 34 includes a support shaft 341. The top of the support shaft 341 is movably butted against the side of the active square shaft 32. The bottom end of the support shaft 341 is inserted with an inner plug shaft 342 through a through hole, and the bottom end of the inner plug shaft 342 is connected with a support leg 343.

[0023] A locking bolt 344 is inserted into the bottom side of the support shaft 341 through a threaded hole, and the shaft end of the locking bolt 344 is inserted into the positioning hole of the inner plug shaft 342.

[0024] A first plug shaft 33 is inserted into the surface of the steel cylinder 31 through a through hole, and a plurality of positioning holes are equidistantly arranged on the surface of the active square shaft 32.

[0025] The bottom end of the steel cylinder 31 is connected with a positioning seat 36. A second plug shaft 35 is horizontally inserted through the side of the support shaft 341 through a through hole.

[0026] The lifting component 4 includes two bottom frames 41 fixed to the side of the hopper end of the tractor head 1. A first hydraulic cylinder 42 is installed in each of the two bottom frames 41. The top end of the piston rod of the first hydraulic cylinder 42 is connected with a support plate 43. The two support plates 43 are butt-jointed and fixed through a connecting plate 44, and a rubber pad 45 is arranged at the top end of the support plate 43.

[0027] Two positioning columns 64 are symmetrically connected to the left and right sides of the bottom end of the clamping plate 63, and the positioning columns 64 are inserted into the fixed seat 61 through through grooves. The bottom end of the fixed seat 61 is fixed on the surface of the hopper end of the tractor head 1. A second hydraulic cylinder 62 is installed on the right side of the bottom end of the clamping plate 63, and the cylinder seat end of the second hydraulic cylinder 62 is fixed on the surface of the hopper end of the tractor head 1.

[0028] The bottom end of the clamping plate 63 is provided with a blade end. The reinforcing fitting 65 includes a fixed stop 653, and the fixed stop 653 is movably installed inside the card slot of the clamping plate 63. A chute adapted to the clamping plate 63 is formed on the side of the fixed stop 653. A side plate 652 is connected to the side of the fixed stop 653, and a third hydraulic cylinder 651 is installed on the right side of the side plate 652. The third hydraulic cylinder 651 is installed on the bottom surface of the clamping plate 63.

[0029] Since the opening end of the card slot of the clamping plate 63 and the hook column 5 are on the same vertical horizontal line, it is convenient to engage with the hook column 5. The hook column 5 can be locked and reinforced by the reinforcing fitting 65, avoiding the separation of the hook column 5 and the clamping plate 63 during the towing of the vehicle frame 21. The movable square shaft 32 can be pulled in and out of the steel cylinder 31, enabling the auxiliary support fitting 34 to be displaced, thereby adapting to the bucket ends of towing tractors 1 with different widths, improving the adjustability and flexibility of the device. Under normal conditions, the support shaft 341 is parallel to the bottom end of the vehicle frame 21, and the support shaft 341 can be retracted and placed in the L-shaped support plate end at the bottom end of the vehicle frame 21 to ensure the retraction and placement effect of the support shaft 341.

[0030] By moving the inner insertion shaft 342 downward in the support shaft 341, the height of the vehicle frame 21 can be adapted. With the design of the support feet 343 at the bottom end of the inner insertion shaft 342, the support feet 343 can contact the ground surface, thereby ensuring the standing support effect of the support shaft 341. After the adjustment of the inner insertion shaft 342 is completed, the locking bolt can be passed through the support shaft 341 and inserted into the positioning hole of the inner insertion shaft 342, thereby ensuring the stability of the inner insertion shaft 342 after adjustment. By pulling the movable square shaft 32 in and out of the steel cylinder 31, the position of the auxiliary support fitting 34 can be changed. When the adjustment of the auxiliary support fitting 34 is completed, the first insertion shaft 33 can be passed through the steel cylinder 31 and inserted into the positioning hole of the movable square shaft 32, thereby ensuring the stability of the movable square shaft 32 after installation.

[0031] When the support shaft 341 rotates perpendicular to the ground surface, the second insertion shaft 35 is passed through the support shaft 341 and inserted into the positioning hole of the positioning seat 36, thereby vertically fixing the support shaft 341 and preventing the support shaft 341 from shaking during vertical support. By the telescopic movement of the piston rod end of the first hydraulic cylinder 42, the support plate 43 can be controlled to temporarily lift the vehicle frame 21, thereby facilitating the adjustment of the vehicle frame 21. When the support plate 43 supports the vehicle frame 21, the rubber pad 45 at the top end of the support plate 43 can reduce the wear degree of the vehicle frame 21 during support.

[0032] The height of the adjusting clamping plate 63 can be controlled by the telescopic movement of the piston rod end of the second hydraulic cylinder 62, which facilitates the docking of the clamping plate 63 with the hanging column 5 during the up-and-down movement. When the clamping plate 63 moves, the through groove of the fixed seat 61 can limit and guide the positioning column 64 to ensure the stability of the up-and-down movement of the clamping plate 63 and prevent the vertical telescopic movement of the piston rod end of 63 from being affected. A frame end is provided on the surface of the hopper end of the tractor head 1, and a baffle end is provided on the surface of the frame end, which can facilitate the positioning of the vehicle frame 21. When the vehicle frame 21 fits with the baffle end, the position of the hanging column 5 can be adapted to the square slot of the clamping plate 63.

[0033] When the hanging column 5 is inserted into the card slot of the clamping plate 63, the piston rod end of the third hydraulic cylinder 651 can be telescoped to push the side plate 652, and then the position of the fixed stop 653 can be adjusted to facilitate the locking of the hanging column 5. A limiting groove adapted to the hanging column 5 is opened on the inner side of the fixed stop 653 to further lock and fix the hanging column. When the fixed stop 653 moves, the fixed stop 653 can further reinforce the hanging column 5. The hanging column 5 is composed of a column end and a disc end structure. During the clamping process, the disc end of the hanging column 5 can cooperate with the card slot of the clamping plate 63 to ensure the docking stability of the hanging column 5 and the clamping plate 63.

[0034] Working principle: First, according to the attached Figure 6 and the attached Figure 7 As shown, the third hydraulic cylinder 651 is started. The telescopic movement of the shaft end of the third hydraulic cylinder 651 can push the side plate 652. The movement of the side plate 652 can control the movement of the fixed stop 653 in the card slot of the clamping plate 63, so that the square slot at the top of the clamping plate 63 is exposed. At this time, by reversing the tractor head 1, the left side of the hanging column 5 can be displaced into the square slot of the clamping plate 63. At this time, the piston rod end of the second hydraulic cylinder 62 retracts, which can drive the clamping plate 63 to move downward, and then control the separation of the hanging column 5 and the clamping plate 63. At this time, according to the attached Figure 5 As shown, the first hydraulic cylinder 61 can be started, and the piston rod of the first hydraulic cylinder 61 can be telescoped to push the support plate 43. The support plate 43 presses on the vehicle frame 21, and the vehicle frame 21 can be lifted; Secondly, according to the attached Figure 2 and the attached Figure 4As shown in the figure, when the trailer end of the tractor head 1 is separated from the vehicle frame 21, first, the 341 support shaft, the first insertion shaft 33 and the second insertion shaft 35 on the side of the steel cylinder 31 are pulled out and reserved. The movable square shaft 32 is pulled out from the outer part of the steel cylinder 31, so that the auxiliary support fitting 34 moves outward to the upper oblique side of the trailer end of the tractor head 1. At this time, the first insertion shaft penetrates through one side of the steel cylinder 31 and is inserted into the positioning hole of the movable square shaft 32 for fixation. At the same time, the support shaft 341 is rotated so that the support shaft 341 is vertically placed, and the second insertion shaft 35 penetrates through the support shaft 341 and is inserted into the positioning hole of the positioning seat 36, so as to fix the support shaft 341. At this time, the inner insertion shaft 342 is pulled down, and the inner insertion shaft 342 can be controlled to move downward in the support shaft 341, and then the support feet 343 are adjusted to support on the ground surface. At this time, the locking bolt 344 penetrates through the support shaft 341 and is inserted into the inner insertion shaft 342 for locking and fixation; Finally, the piston rod end of the first hydraulic cylinder 42 is retracted, which can drive the support plate 43 to move downward, so that the support plate 43 is separated from the bottom end of the vehicle frame 21. At this time, the tractor head 1 can be completely separated from the vehicle frame 21, and then it is convenient for the tractor head 1 to move under other vehicle frames 21 for docking. Docking can be carried out without using external tools, improving the docking efficiency. In addition, a fixing component 6 is also arranged at the top end on the right side of the vehicle frame 21, which can also facilitate the series docking between two vehicle frames 21 and realize modular assembly.
