Description

Technical Field

[0001] The present invention relates to the technical field of terminal transportation, in particular to a raisable climbing crawler transporter. Background Art

[0002] In dock transportation scenarios, cargo transfers often face complex and ever-changing road conditions. Dock areas not only have flat concrete surfaces but also often involve height differences between ship decks and the ground, temporary ramps, slippery roads, and other complex working conditions. This places extremely high demands on the adaptability, trafficability, and safety of transportation equipment.

[0003] Tracked transporters, thanks to their large track-to-ground contact area, have excellent maneuverability in complex road conditions, making them particularly useful in port cargo transportation. However, most existing tracked transporters used for port transportation only have cargo transport functions and are unable to automatically unload cargo. Transferring cargo from the transporter to a ship, warehouse, or other designated location often requires additional lifting equipment or manual handling, which not only increases operational steps and labor costs but also reduces overall transportation efficiency.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] like Figure 1-4 As shown, the embodiment of the present application discloses a liftable climbing crawler transport vehicle, comprising a frame 10, with a crawler assembly 20 provided at the bottom of the front frame 10. The crawler assembly 20 is used to support the frame 10 and control the movement. Two side panels 11 are arranged at intervals along the length of the frame 10. A plurality of rolling shafts 12 are provided between the two side panels 11 along their length, and a drive assembly 30 is provided inside the frame 10 to drive the plurality of rolling shafts 12 to rotate synchronously. The plurality of rolling shafts 12 are used to place cargo. The drive assembly 30 drives the rolling shafts 12 to move the cargo on the frame 10, thereby realizing automatic loading and unloading of cargo and saving manpower. Two sets of brackets 40 are provided along the length of the frame 10. The brackets 40 are provided with a plurality of strip-shaped grating plates 41 spaced apart along the length of the frame 10. The strip-shaped grating plates 41 are staggered relative to the rolling shafts 12. A lifting assembly 50 is provided within the frame 10 to drive the brackets 40 upward and downward. The lifting assembly 50 drives the brackets 40 upward and downward, causing the strip-shaped grating plates 41 to rise and contact the bottom of the cargo, thereby increasing friction under the cargo and preventing the cargo from rolling on the rolling shafts 12 when climbing a slope. A rotating shaft 60 is provided at both the front and rear ends of the bottom of the frame 10, perpendicular to the length of the frame 10. Tripods 61 are provided at both ends of the rotating shaft 60, with outrigger cylinders 62 provided on the tripods 61. A rotating assembly 70 is provided within the frame 10 to drive the rotating shaft 60. When the unloading position is higher than the cargo position, the rotating shaft 60 can be driven by the rotating component 70 to rotate so that the outrigger cylinder 62 is in a vertical state, and then the outrigger cylinder 62 is started to adjust the height of the entire vehicle body so that the bottom of the cargo is at the same height as the unloading platform. In this way, the cargo can be moved to the unloading platform through the rolling shaft 12, without the need for manual handling or the use of lifting equipment. The structure is simple and practical.

[0028] Specifically, the vehicle frame 10 includes a first crossbeam 13 and a second crossbeam 14 spaced apart from each other in a front-to-rear manner. A bridge frame 15 is provided on both the first and second crossbeams 13, 14. The first and second crossbeams 13, 14 provide a solid foundation for the vehicle body. The bridge frame 15 connects the first and second crossbeams 13, 14 to enhance overall structural strength and stability. Other components are mounted on the bridge frame 15.

[0029] The track assembly 20 includes two track beams 21 mounted at the ends of the first and second crossbeams 13 and 14. Guide wheels 22 and drive wheels 23 are mounted on the front and rear ends of the track beams 21, respectively. Rubber tracks 24 are mounted on both the guide and drive wheels 22 and 23. A power system is located within the vehicle frame 10 to drive the two drive wheels 23. The power system drives the two drive wheels 23, which in turn drives the rubber tracks 24, enabling the vehicle to move. The tracked structure improves the transport vehicle's maneuverability on complex terrain, particularly on slopes and muddy roads, preventing slippage and enhancing driving stability.

[0030] The drive assembly 30 includes an I-beam 31 disposed between the first crossbeam 13 and the second crossbeam 14. A drive motor 32 is mounted on the I-beam 31, and a drive gear 33 is mounted on the output shaft of the drive motor 32. Two driven gears 34 are spaced apart at one end of the rolling shafts 12. The two driven gears 34 located at the same position on the two middle rolling shafts 12 are connected to the drive gear 33 via a drive chain (not shown) to form a transmission pair. Two driven gears 34 located at other positions on the two middle rolling shafts 12 are connected to corresponding driven gears 34 on the outer rolling shafts 12 via a drive chain 35 to form a transmission pair. The remaining adjacent rolling shafts 12 are connected to their corresponding driven gears 34 via a drive chain to form a transmission pair. Thus, the drive motor 32 drives the drive gear 33 to rotate, and the transmission chain and transmission chain 35 drive all rolling shafts 12 to rotate synchronously, thereby enabling the movement of cargo on the vehicle frame 10, facilitating loading and unloading and saving manpower.

[0031] The lifting assembly 50 includes four mounting plates 51 mounted inside the bridge 15, corresponding to the four corners of the bracket 40. Lifting cylinders 52 are mounted on the mounting plates 51, and connecting plates 42 are located at the four corners of the bracket 40. The piston rod ends of the lifting cylinders 52 are fixedly connected to the connecting plates 42. The four sets of lifting cylinders 52 push the bracket 40 upward and downward, ensuring uniform lifting force and stable and reliable lifting.

[0032] The rotating assembly 70 includes a rotating cylinder 71. A connecting bracket 63 is fixedly mounted on the rotating shaft 60. The cylinder end of the rotating cylinder 71 is hingedly connected to the bridge 15, and the piston rod end is hingedly connected to the connecting bracket 63. The cooperation between the rotating cylinder 71 and the connecting bracket 63 drives the rotating shaft 60 to rotate, thereby driving the tripod 61 and the outrigger cylinder 62 to rotate, so that the outrigger cylinder 62 rotates to the working position.

[0033] Lifting lugs 16 are provided at both the front and rear ends of the side panels 11, facilitating the lifting and transport of the equipment to and from transport vehicles. This facilitates the movement and deployment of the equipment between different work sites, saving time and labor costs in equipment handling and increasing its flexibility. Several hoops 17 are provided at intervals along the length of the outer surface of the side panels 11 to further secure cargo with ropes to prevent it from slipping during transport.

[0034] The operating principle of the liftable, hill-climbing crawler transporter in this embodiment is as follows: when transporting cargo, the lifting cylinder 52 synchronously drives the bracket 40 upward, driving the strip grid plates 41 upward until the top of the strip grid plates 41 contacts the bottom of the cargo. Because the strip grid plates 41 are staggered with the rolling shafts 12, the strip grid plates 41 are located exactly between two rolling shafts 12. The strip grid plates 41 and the rolling shafts 12 jointly support the cargo, increasing the friction under the cargo, effectively preventing the cargo from sliding. This prevents the cargo from rolling when climbing a slope, effectively improving the cargo's stability. When transporting heavy cargo, ropes can also be used to secure the cargo to the hoop 17 to further enhance its stability.

[0035] When unloading is required, the rotating shaft 60 is driven to rotate by cooperating with the rotating cylinder 71 and the connecting frame 63, which drives the tripod 61 and the outrigger cylinder 62 to rotate, so that the outrigger cylinder 62 rotates to a vertical position, and then the outrigger cylinder 62 is started to adjust the height of the entire vehicle body so that the bottom of the cargo is at the same height as the unloading platform; the lifting cylinder 52 is then used to synchronously drive the bracket 40 to move downward, driving the strip grid plate 41 to descend and separate from the bottom of the cargo; then the drive motor 32 is started to drive the rolling shaft 12 to roll, and the cargo is transferred to the unloading platform. There is no need for manual handling or the use of lifting equipment. The structure is simple and practical.

[0036] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
