[0003] Currently, common equipment transportation methods mostly involve flatbed trailers or hoisting transfers. However, these methods generally have the following problems: First, some devices with tires at the bottom cannot be quickly docked with transport vehicles, and steering control and adjustment require manual pushing and pulling or limit devices, which is inefficient. Second, the loading and unloading process is cumbersome and requires the assistance of large cranes or sliding rail equipment, which increases the difficulty of on-site operations. Third, pipelines and cables are prone to dragging, tangling, or even being damaged during transportation, posing certain safety hazards. Therefore, this application proposes a large-scale mechanical rapid transportation device. Utility Model Content

[0004] This application proposes a rapid transport device for large machinery. By setting up a series of structures, it solves the problems that the current common equipment transportation methods, which mostly use flatbed trailers or hoisting transfers, generally have the following issues: First, some devices with tires at the bottom cannot be quickly docked with transport vehicles, and steering control and adjustment require manual pushing and pulling or limit devices, which is inefficient; second, the loading and unloading process is cumbersome and requires the assistance of large cranes or sliding rail equipment, which increases the difficulty of on-site operations; third, pipelines and cables are prone to dragging, tangling, or even being damaged during transportation, which poses certain safety hazards.

[0005] This application proposes a large-scale rapid transport device for machinery, including a vehicle platform and a connecting frame. Two sets of mounting platforms are welded to the rear edge of the vehicle platform. A tow arm is hinged to the mounting platform, and the front end of the tow arm rests on the vehicle platform. A connecting frame is hinged to the bottom of the mounting platform, and a hinge seat is hinged to the front end of the connecting frame. A rear wheel is mounted at the end of the hinge seat. Two sets of rear wheels are provided, and a connecting arm is fixedly connected between the two sets. A center seat is fixedly connected to the middle position of the rear end of the connecting frame. A steering hydraulic rod is hinged between the center seat and one set of hinge seats. A lifting hydraulic rod is installed between the mounting platform and the hinge seat.

[0006] Furthermore, the rear wheels are symmetrically distributed about the center of the connecting arm, and the length of the connecting arm is greater than the width of the vehicle platform.

[0007] Furthermore, both sides of the bottom of the connecting frame are fixedly connected to a mounting base, and the mounting base is movably connected to a foot, which is made of rubber.

[0008] Furthermore, a tripod is welded to the front of the vehicle platform. The tripod is an isosceles triangular structure, and a tow hook is rotatably connected to the front of the tripod.

[0009] Furthermore, a fixing plate is fixedly connected to the tripod, and the fixing plate is fixed to the tripod by bolts. A wire frame is welded to the top of the fixing plate. A wire outlet hole and a wire inlet hole are respectively opened at the center of the front and rear ends of the vehicle platform. The wire inlet hole, the wire outlet hole and the wire frame are all located at the horizontal center line of the vehicle platform.

[0010] Furthermore, a metal semi-ring is welded to the top of the wire frame, and a notch is opened at the top of the semi-ring.

[0011] Furthermore, multiple sets of rope hooks are welded at equal intervals on both sides of the vehicle platform, and the rope hooks are symmetrically distributed on both sides of the vehicle platform.

[0012] Furthermore, welding plates are welded to the four corners of the bottom of the vehicle platform, and pin holes are opened on both the front and rear sides of the vehicle platform. Pin rods are inserted into the pin holes and pass through the welding plates.

[0013] As can be seen from the above technical solution, during use, the lifting hydraulic rod raises the mounting platform, thereby lifting the rear of the vehicle platform as a whole, causing the rear wheels and connecting frame to leave the ground and form a transport and towing state. The rear wheels are installed at the end of the articulated seat, which is connected by a connecting arm to form a bridge structure. The rear wheels will not obstruct the transport movement when not on the ground, and their angle is adjustable. The steering hydraulic rod can drive the rear wheels to adjust the steering angle, making the towing direction flexible and controllable, adapting to different roads or turning paths. The bottom of the fixed seat is movably connected to rubber feet, which can ground first to absorb the impact during the descent of the vehicle platform, playing a buffer and shockproof role, and preventing metal parts from directly hitting the ground and causing damage. The lifting hydraulic rod and the steering hydraulic rod are double-acting hydraulic cylinders, model Y-HSG-E100 / 50-250, with a cylinder diameter of 50mm and a stroke of 150mm. They have fast response speed and stable operation, making them suitable for the transport of large machinery.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this large machinery rapid transport device not only realizes the rapid lifting of the vehicle platform and the steering of the rear wheels, making it suitable for the transport of large machinery, but also prevents displacement, deviation or rollover caused by vibration, acceleration or turning during driving, and avoids the pipeline from swinging or dragging on the ground during driving, causing entanglement or damage.

[0015] (1) By setting up an installation platform, lifting hydraulic rod, rear wheels, center seat and steering hydraulic rod, the vehicle platform can be lifted by the hydraulic control system before transportation, so as to quickly lift the vehicle platform and turn the rear wheels, which is convenient for the tripod to be hooked at the rear of the transport vehicle and to be towed as a whole. It is suitable for the transportation of large machinery and improves transportation efficiency.

[0016] (2) By setting up a tripod, tow hook, fixing plate, wire frame, rope hook and vehicle platform, the tripod is welded as a whole at the front end of the vehicle platform to ensure fast and stable towing connection. The rope hooks are symmetrically distributed on the left and right to cooperate with high-strength nylon ropes to prevent displacement, deviation or rollover due to vibration, acceleration or turning during driving.

[0017] (3) By setting inlet hole, outlet hole, wire frame, fixing plate, pin hole and pin rod, the wire frame is used to hang the high pressure oil pipe and control wire harness of the hydraulic system. The wire harness enters through the inlet hole and exits through the outlet hole, and is connected to the interface of the lifting hydraulic rod and the steering hydraulic rod respectively. It is fixed to the bottom of the vehicle platform with pin rod to avoid the pipeline swinging or dragging on the ground during the driving process, causing entanglement or damage.

[0025] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] See Figures 1-4 .

[0027] Currently, common equipment transportation methods mostly involve flatbed trailers or hoisting transfers. However, these methods generally have the following problems: First, some devices with tires at the bottom cannot be quickly docked with transport vehicles, and steering control and adjustment require manual pushing and pulling or limit devices, resulting in low efficiency. Second, the loading and unloading process is cumbersome, requiring the assistance of large cranes or sliding rail equipment, increasing the difficulty of on-site operations. Third, pipelines and cables are prone to dragging, tangling, or even damage during transportation, posing certain safety hazards. Therefore, this application proposes a large-scale mechanical rapid transportation device, including a flatbed trailer. The platform 8 and connecting frame 7 have two sets of mounting platforms 3 welded to their rear edge. Trailing arms 4 are hinged to the mounting platforms 3, with their front ends resting on the platform 8. The connecting frame 7 is hinged to the bottom of the mounting platforms 3, and a hinge seat 19 is hinged to the front end of the connecting frame 7. Rear wheels 1 are mounted at the ends of the hinge seats 19, and there are two sets of rear wheels 1. Connecting arms 20 are fixedly connected between the two sets. A center seat 17 is fixedly connected to the middle of the rear end of the connecting frame 7. A steering hydraulic rod 18 is hinged between the center seat 17 and one set of hinge seats 19. Lifting hydraulic rods 2 are installed between the mounting platforms 3 and the hinge seats 19. The rear wheels 1 are symmetrically distributed about the center of the connecting arms 20, and the length of the connecting arms 20 is greater than the width of the platform 8. Fixed seats 6 are fixedly connected to both sides of the bottom of the connecting frame 7, and footings 5, made of rubber, are movably connected to the fixed seats 6. Specifically, the lifting hydraulic rod 2 raises the mounting platform 3, thereby lifting the rear of the vehicle platform 8, causing the rear wheels 1 and connecting frame 7 to leave the ground and form a transport and towing state. The rear wheels 1 are installed at the end of the hinge seat 19, which is connected by the connecting arm 20 to form a bridge structure. The rear wheels 1 will not hinder the transport movement when not on the ground, and their angle is adjustable. The steering hydraulic rod 18 can drive the rear wheels 1 to adjust the steering angle, making the towing direction flexible and controllable, adapting to different roads or turning paths. The bottom of the fixed seat 6 is movably connected to the rubber feet 5, which can first touch the ground to absorb the impact during the descent of the vehicle platform 8, playing a buffer and shockproof role, and avoiding damage caused by direct impact of metal parts to the ground.

[0028] Furthermore, a tripod 10 is welded to the front end of the carrier platform 8. The tripod 10 is an isosceles triangular structure, and a tow hook 11 is rotatably connected to the front end of the tripod 10. Multiple sets of rope hooks 9 are welded at equal intervals on both sides of the carrier platform 8. The rope hooks 9 are symmetrically distributed on both sides of the carrier platform 8. Specifically, the tripod 10 is welded as a whole to the front end of the carrier platform 8, and a tow hook 11 is rotatably connected to the front end. The tow hook 11 is used to connect with the standard tow hook at the rear of the transport vehicle to ensure a fast and stable towing connection. The rope hooks 9 are symmetrically distributed on the left and right sides and are used to work with high-strength nylon ropes to bind and fix the workpiece laterally and longitudinally during the transportation of large machinery.

[0029] Furthermore, a fixing plate 14 is fixedly connected to the tripod 10, and the fixing plate 14 is fixed to the tripod 10 by bolts. A wire frame 12 is welded to the top of the fixing plate 14. A wire outlet hole 16 and a wire inlet hole 15 are respectively opened at the center of the front and rear ends of the vehicle platform 8. The wire inlet hole 15, the wire outlet hole 16 and the wire frame 12 are all located at the horizontal center line of the vehicle platform 8. A metal semi-ring is welded to the top of the wire frame 12, and a notch is opened at the top of the semi-ring. Welding plates 21 are welded to the four corners of the bottom end of the vehicle platform 8. Pin holes 13 are opened at the front and rear of both side walls of the vehicle platform 8, and a pin is inserted into the pin hole 13. There is a pin 22, which passes through the welding piece 21. Specifically, the high-pressure pipeline of the hydraulic system enters from the inlet hole 15 at the front end of the vehicle platform 8. A metal semi-ring is welded to the top of the wire frame 12. A notch is opened at the center of the top of the metal semi-ring for hanging the high-pressure oil pipe and control harness of the hydraulic system. The harness is then guided into the vehicle platform 8 through the inlet hole 15 and led out from the bottom outlet hole 16, respectively connecting to the interfaces of the lifting hydraulic rod 2 and the steering hydraulic rod 18. The hydraulic control signal is provided by the hydraulic control assembly at the rear of the transport vehicle and is fixed to the bottom end of the vehicle platform 8 by the pin 22.

[0030] As can be seen from the above technical solution, before the device is put into operation, a quick connection is achieved by using the tow hook 11 at the front end of the tripod 10 to the standard tow hook at the rear of the transport vehicle. The hydraulic control system output pipeline at the rear of the transport vehicle is passed through the inlet hole 15 and hung on the metal semi-ring at the top of the cable frame 12 for guidance. Then, it is led out through the outlet hole 16 to the interface of the lifting hydraulic rod 2 and the steering hydraulic rod 18. The entire hydraulic system pipeline is fixed by pins 22 through the pin holes 13 on both sides of the carrier platform 8, so that the hydraulic wiring harness is neatly fixed and does not drag on the ground, ensuring safe wiring. After placing the large machinery to be transported on the carrier platform 8, nylon ropes are used to bind and fix it to multiple sets of rope hooks 9 that are equally spaced on both sides of the carrier platform 8 in a crosswise and longitudinal manner to ensure the stability of the machinery during transportation. Without tilting, the hydraulic control system at the rear of the transport vehicle is activated. The lifting hydraulic rod 2 raises the mounting platform 3, thereby lifting the entire rear of the vehicle platform 8. This causes the rear wheels 1 and connecting frame 7 to leave the ground and enter a towing state. The rear wheels 1 are mounted at the end of the articulated seat 19, which is connected by the connecting arm 20 to form a bridge structure. The rear wheels 1 do not obstruct the transport movement when not on the ground, and their angle is adjustable. The steering hydraulic rod 18 can be used to drive the rear wheels 1 to adjust the steering angle, making the towing direction flexible and controllable, adapting to different roads or turning paths. The bottom of the fixed seat 6 is movably connected to the rubber feet 5, which can first touch the ground to absorb the impact during the descent of the vehicle platform 8, playing a buffering and shockproof role and preventing metal parts from directly hitting the ground and causing damage.
