Description

Technical Field

[0001] This invention relates to the field of loading and unloading platform technology, and in particular to a vehicle loading and unloading transportation device. Background Technology

[0002] In automobile loading and unloading operations, there is often a height difference between the transport platform of the loading and unloading equipment and the carrying car or ship. Due to the lack of an effective planar adaptation structure, when the car is getting on and off the transport platform, the chassis is prone to scraping against the edge of the platform or the edge of the carrier. This can lead to minor damage to the chassis coating and deformation of parts, or even serious damage such as chassis oil leaks and failure of key components, increasing the cost of car maintenance and even affecting the safety of driving. This risk of scraping is even higher for cars, sports cars and other models with low chassis, which greatly limits the applicability of the equipment.

[0003] In vehicle transfer operations, logistics transfer stations need to transfer vehicles from the original cargo compartment to a new one. Traditional loading and unloading equipment lacks flexible operating functions, the operation process is cumbersome and consumes a lot of manpower and time, and it is difficult to ensure the stable connection between auxiliary tools, platforms and cargo compartments, which increases the risk of vehicles slipping and cannot quickly meet the needs of rapid transfer of batches of vehicles.

[0004] Meanwhile, during the loading and unloading of vehicles, loading and unloading equipment needs to come into contact with the carrier truck or ship. Traditional equipment often experiences rigid metal-to-metal collisions when in contact with these carriers. The impact force generated by the collision can cause deformation and wear at the docking points, shortening the equipment's lifespan and increasing maintenance and replacement costs. It can also cause scratches and dents to the edges of train carriages and the surfaces of ship decks, further increasing the overall cost of logistics and transportation and affecting the normal use of the transport carrier. In some scenarios, in order to alleviate the problem of rigid collisions with traditional equipment, outer tires are used as padding at the docking points to achieve "soft contact" through the elasticity of the tires. The load-bearing capacity of the outer tires depends on the elastic support of the rubber material. However, after long-term use, the rubber will age due to oxidation and ultraviolet radiation, resulting in hardening of the rubber, reduced elasticity, and decreased structural strength. It will also make hard contact with the carrier, posing a great threat to operational safety. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle loading and unloading transportation device that solves the technical problems of easy scratching of the vehicle chassis due to the height difference between the vehicle and the carrier and the lack of an effective matching structure during vehicle loading and unloading operations, the cumbersome and inefficient transportation process, and the damage and increased cost caused by rigid collision between the equipment and the carrier.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A vehicle loading and unloading transport device includes a transport vehicle body and a loading and unloading lifting platform. Guardrails are installed on both sides of the transport vehicle body. A platform lifting mechanism is vertically installed on one side of the transport vehicle body, and a platform tension lifting mechanism is vertically installed on the other side. A PLC control cabinet is installed on the side panel of the transport vehicle body. The loading and unloading lifting platform is installed inside the transport vehicle body. Guardrails are installed on both sides of the loading and unloading lifting platform. A set of bending force-bearing members are installed opposite each other on the loading and unloading lifting platform. Limiting sliding holes are provided on the bending force-bearing members, and the platform lifting mechanism slides within the limiting sliding holes. Lifting devices are also installed on both sides of the loading and unloading lifting platform. The lifting blocks are connected to the platform's lifting mechanism at both ends. The bottom of the transport vehicle is equipped with an electric suction buffer plate and a hydraulic control system. Threaded retractable outriggers are installed on the sides of the transport vehicle. A towing hook is installed on the transport vehicle near the sloping beam. The threaded retractable outriggers and the towing hook form a double fixation, ensuring that the equipment does not tilt or shift during operation. The guardrails on both sides of the transport vehicle and the loading / unloading lifting platform prevent the vehicle from slipping, significantly improving the safety factor and fully protecting the safety of the vehicle and operators. The towing hook facilitates towing and moving the equipment to the construction site.

[0008] The platform lifting mechanism includes a hydraulic cylinder, a spherical bearing, and a limiting groove ring. The spherical bearing is installed on the telescopic rod of the hydraulic cylinder, and the outer ring of the spherical bearing is a limiting groove ring, which slides in the limiting sliding hole.

[0009] The platform lifting mechanism includes an outer frame, a second hydraulic cylinder, a movable sliding block, a first fixed pulley block, a second fixed pulley block, and a traction rope. The outer frame is installed on the transport vehicle. The second hydraulic cylinder is vertically installed in the outer frame. The movable sliding block is installed at the top of the telescopic rod of the second hydraulic cylinder. The first and second fixed pulley blocks are installed parallel to each other on both sides of the inner top of the outer frame. The pulleys of the first fixed pulley block and the pulleys of the movable sliding block are perpendicular to each other. The traction rope passes through the first fixed pulley block, the movable sliding block, and the second fixed pulley block in sequence. The two ends of the traction rope are connected to the two ends of the lifting block. The width of the outer frame is greater than the width of the lifting block, and the lifting block is limited within the outer frame to prevent lateral displacement of the lifting block. The structure is simple, the force is small, and the cost is low.

[0010] The loading and unloading lifting platform is composed of a load-bearing beam and a sloping beam that are hinged together. A set of inclined hydraulic cylinders is installed on the load-bearing beam, and the inclined hydraulic cylinders are fixedly connected to the sloping beam by a rope. An electric suction buffer plate is installed at the bottom of the load-bearing beam.

[0011] In summary, the present invention has the following beneficial effects:

[0012] Through the platform lifting mechanism and spherical bearings, the loading and unloading lifting platform can fit snugly with the carrying car or the carrying ship, eliminating a large height difference and forming a nearly flat transport plane. This avoids the chassis being scratched and damaged when the car is loaded onto or off the platform, and is suitable for cars of all chassis heights.

[0013] In terms of transfer at the transfer station, the platform lifting mechanism and the height adjustment of the loading and unloading lifting platform can form a bridge between the carriages, and the cars can be directly transferred to the platform. The transfer time at the transfer station is significantly shortened compared with traditional equipment, meeting the needs of rapid transfer of batches of cars.

[0014] Meanwhile, the elastic rubber layer of the electro-absorbing buffer plate can absorb a large amount of impact force, achieving soft contact with train carriages and ships. Its electromagnetic adsorption function can also maintain the docking state and prevent detachment. Compared with the prior art, the present invention avoids equipment deformation and scratches caused by rigid collisions, effectively reduces equipment maintenance costs, and protects the docking carrier from damage.

[0022] See Figures 1 to 4A vehicle loading and unloading transport device includes a transport vehicle body 1 and a loading and unloading lifting platform 2. Guardrails 11 are installed on both sides of the transport vehicle body 1. A platform lifting mechanism 3 is vertically installed on one side of the transport vehicle body 1, and a platform tension lifting mechanism 4 is vertically installed on the other side of the transport vehicle body 1. A PLC control cabinet 5 is installed on the side panel of the transport vehicle body 1. The loading and unloading lifting platform 2 is installed inside the transport vehicle body 1. Guardrails 12 are installed on both sides of the loading and unloading lifting platform 2. Threaded retractable... Outrigger 13, a traction hook 14 is installed on the transport car 1 near the side of the inclined beam 21, a set of opposing bending force-bearing components 6 is installed on the loading and unloading lifting platform 2, a limiting sliding hole 7 is installed on the bending force-bearing component 6, the platform lifting mechanism 3 slides in the limiting sliding hole 7, and lifting blocks 8 are also installed on both sides of the loading and unloading lifting platform 2. The two ends of the lifting blocks 8 are respectively connected to the platform tension lifting mechanism 4. The bottom of the transport car 1 is equipped with an electric suction buffer plate 9 and a hydraulic control system 10.

[0023] See Figure 2 The platform lifting mechanism 3 includes a hydraulic cylinder 30, a spherical bearing 31, and a limiting groove ring 32. The spherical bearing 31 is installed on the telescopic rod of the hydraulic cylinder 30. The outer ring of the spherical bearing 31 is the limiting groove ring 32, which slides in the limiting sliding hole 7.

[0024] See Figure 4 The platform lifting mechanism 4 includes an outer frame 41, a second hydraulic cylinder 42, a movable sliding assembly 43, a first fixed pulley assembly 44, a second fixed pulley assembly 45, and a traction rope 46. The outer frame 41 is installed on the transport vehicle 1. The width of the outer frame 41 is greater than the width of the lifting block 8, and the lifting block 8 is limited within the outer frame 41. The second hydraulic cylinder 42 is vertically installed in the outer frame 41. The movable sliding assembly 43 is installed at the top of the telescopic rod of the second hydraulic cylinder 42. The first fixed pulley assembly 44 and the second fixed pulley assembly 45 are arranged parallel to each other on both sides of the inner top of the outer frame 41. The pulleys of the first fixed pulley assembly 44 and the movable sliding assembly 43 are perpendicular to each other. The traction rope 46 passes through the first fixed pulley assembly 44, the movable sliding assembly 43, and the second fixed pulley assembly 45 in sequence. The two ends of the traction rope 46 are connected to the two ends of the lifting block 8 respectively.

[0025] See Figure 3 The loading and unloading lifting platform 2 is composed of a load-bearing beam plate 20 and a slope beam plate 21 that are movably hinged. A set of inclined hydraulic cylinders 22 is installed on the load-bearing beam plate 20. The inclined hydraulic cylinders 22 are fixedly connected to the slope beam plate 21 by a pull rope 23. An electric suction buffer plate 9 is installed at the bottom of the load-bearing beam plate 20.

[0026] The car travels from the original carriage to the load-bearing beam 20 via the ramp beam 21, with guardrail 11 and guardrail 22 providing full protection. After the car stops, the angle of the ramp beam 21 is slightly adjusted, and the car drives directly into the new carriage via the other end of the ramp beam 21.

[0027] Example 1: Eliminating height differences and fitting the load-bearing vessel together;

[0028] See Figures 1 to 4 The transport vehicle 1 is driven to the designated position on the dock. The threaded retractable outrigger 13 on the side of the transport vehicle 1 is unscrewed so that the bottom of the outrigger is in close contact with the ground. The PLC control cabinet 5 is operated to initialize the equipment parameters. The hydraulic control system 10 causes the two lifting platform lifting mechanisms 3 to lift simultaneously to form a slope. The carrying vehicle or carrying ship docks with the transport vehicle 1. The bottom oil outlet valve and bottom oil outlet valve of the hydraulic cylinder 30 are opened. The loading and unloading lifting platform 2 approaches the surface of the carrying vehicle or carrying ship according to its own weight. The joint bearing 31 plays a role in fine-tuning the angle and compensating for minor deviations. The lower half of the cylinder pipe of the hydraulic cylinder 30 outputs oil and the upper half enters oil, which flows back to the hydraulic control system 10. The bottom of the unloading lifting platform 2 is made of sheet metal and is relatively long to adapt to the deformation process. It is convenient for the electric magnetic block of the electric suction buffer plate 9 at the bottom of the transport vehicle 1 to be energized and attracted to the surface of the carrying vehicle or carrying ship. Then the car is transferred from the loading and unloading lifting platform 2.

[0029] Example 2: Car transfer operations between carriages at a transfer station;

[0030] See Figures 1 to 4 By operating the PLC control cabinet 5 and initializing the equipment parameters, the hydraulic control system 10 causes the two lifting platform lifting mechanisms 3 to lift simultaneously, and the platform pulling lifting mechanism 4 to pull down simultaneously. The transport vehicle docks with the front of the carriage 1, and the transfer vehicle docks with the rear of the carriage 1. By operating the PLC control cabinet 5 to control the hydraulic control system 10 to lower the loading and unloading lifting platform 2 simultaneously, a bridge is formed to carry out the vehicle transfer operation between the carriages of the transfer station. The vehicle directly drives into the new carriage through one end of the loading and unloading lifting platform 2; without the need for auxiliary tools such as shims or temporary ramps, it meets the needs of rapid transfer of batch vehicles, and there is no risk of vehicles slipping throughout the process.

[0031] Example 3: Soft contact docking operation with the support platform;

[0032] See Figures 1 to 4The threaded retractable outriggers 13 are used to fix the equipment. The bottom of the transport vehicle 1 and the bottom of the loading and unloading lifting platform 2 are inspected for electric suction buffer plates 9 to ensure that their elastic rubber layer is undamaged and that the electromagnetic adsorption function is normal. The adsorption pressure parameters of the electric suction buffer plates 9 are set through the PLC control cabinet 5. The PLC control cabinet 5 is operated to initialize the equipment parameters. The hydraulic control system 10 causes the two lifting platform lifting mechanisms 3 to lift simultaneously to form a slope. The carrying vehicle or the carrying ship docks with the transport vehicle 1. The electric suction buffer plates 9 play a buffering role. The platform lifting mechanism 3 slides in the limiting sliding hole 7. Specifically, the limiting groove ring 32 slides in the limiting sliding hole 7 to ensure the stability of the platform. The outer frame 41 of the platform lifting mechanism 4 limits the lifting block 8 to prevent the lifting block 8 from shifting laterally. The loading and unloading lifting platform 2 undergoes slight displacement. The bottom oil outlet valve and bottom oil outlet valve of the hydraulic cylinder 30 are opened. The loading and unloading lifting platform 2 approaches the surface of the carrying car or the carrying ship according to its own weight. The joint bearing 31 plays a role in fine-tuning the angle. Oil is discharged from the lower half of the cylinder pipe of the hydraulic cylinder 30 and oil is fed into the upper half, flowing back to the hydraulic control system 10. The electric magnet of the electric suction buffer plate 9 at the bottom of the carrying car 1 is energized and adsorbed on the surface of the carrying car or the carrying ship to prevent the docking point from detaching and facilitate the transfer of the car from the loading and unloading lifting platform 2.

[0033] After the process is completed, the platform lifting mechanism 4 retracts and lifts one end of the loading and unloading lifting platform 2 near the traction hook 14. The loading and unloading lifting platform 2 slides, and the platform lifting mechanism 3 slides in the limiting sliding hole 7. Then, the bending force-bearing component 6 of the loading and unloading lifting platform 2 slides on the platform lifting mechanism 3 to reset.
