Description

Technical Field

[0001] The present application relates to the technical field of flatbed lifting and transporting equipment, and in particular to a large-tonnage flatbed lifting and transporting vehicle. Background Art

[0002] With the rapid development of the logistics industry, the demand for logistics warehouses is increasing. When goods are transported, forks are often used for transportation, that is, pallet handling vehicles, which refer to non-stacking lifting vehicles equipped with forks. They are often used for the transportation of large objects in warehouses and are usually driven by fuel engines or batteries.

[0003] However, this requires that the size of the goods is within an appropriate range. When the tonnage of the goods is large, conventional forklifts are prone to overturning, and it is not easy to carry out short-distance transportation operations. In addition, when some existing flatbed lift trucks carry large-tonnage goods, the load is usually directly supported by hydraulic cylinders when driving the goods to lift and carry them. This makes it possible for the hydraulic cylinder to shake when carrying large-tonnage goods due to the vibration caused by the start-up of the vehicle body, which will cause additional pressure and wear on the structure and seals of the hydraulic cylinder, thereby affecting the service life of the truck. Summary of the invention

[0004] The present application proposes a large-tonnage flatbed lift truck, which has the advantages of not easily tipping over when transporting large-tonnage goods and a long service life of the truck, and is used to solve the problem that the equipment for transporting goods in existing logistics warehouses is easy to tip over or has a short service life.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a large-tonnage flatbed lifting truck, including a vehicle body, two positioning beams are fixedly installed on one side of the vehicle body, a reinforcement beam is fixedly installed between the two positioning beams, transmission support devices are installed on the two positioning beams, a moving beam is fixedly installed on the top of the transmission support device on each positioning beam, and a load plate is fixedly installed on the top of the two moving beams, and the moving beam and the load plate are driven by a hydraulic cylinder to rise and fall.

[0006] When the hydraulic cylinder drives the load plate to lift the loaded goods, the load plate is moved obliquely upward away from the side of the vehicle body through the transmission support device, and after the load plate loaded with goods is lifted and moved to the highest position, the load plate is supported by the transmission support device.

[0007] Furthermore, the number of the reinforcement beams, reinforcement plates and transmission support devices is no less than two.

[0008] Furthermore, a plurality of equidistantly arranged reinforcement plates are fixedly installed between the two movable cross beams, two positioning members are fixedly installed on one of the reinforcement beams, and both ends of the hydraulic cylinder are movably connected to the reinforcement plates and the positioning members respectively.

[0009] Furthermore, the transmission support device includes a lower fixed shaft I, which is fixedly mounted on the positioning beam, and a linkage rotating plate I is movably mounted on the lower fixed shaft I. An upper fixed shaft I is movably mounted on the end of the linkage rotating plate I away from the lower fixed shaft I, and the upper fixed shaft I is mounted on the movable beam.

[0010] Furthermore, a support block located on one side of the lower fixed axis I is fixedly mounted on the positioning beam, and the top of the support block is movably connected to the bottom of the movable beam.

[0011] Furthermore, when the linkage rotating plate I is rotated to a vertical state, the side surface of the support block is in contact with the side surface of the linkage rotating plate I.

[0012] Further, the transmission support device includes several groups of positioning blocks, the number of the positioning blocks is not less than two, and the number of positioning blocks in each group is two, each group of positioning blocks is fixedly mounted on two positioning beams respectively, a central fixed shaft is fixedly mounted between the two positioning blocks in each group, and the central fixed shaft is arranged in the middle of the positioning blocks, a linkage rotating plate II is movably mounted on the central fixed shaft, the front face of the linkage rotating plate II is in the shape of an obtuse triangle, and the central fixed shaft is close to the obtuse end of the linkage rotating plate II, one of the acute-angled ends of the linkage rotating plate II is movably mounted with an upper fixed shaft II, the upper fixed shaft II is fixedly mounted on the moving beam, the other acute-angled end of the linkage rotating plate II is movably mounted with a lower fixed shaft II, and when the load plate is lowered to the lowest point, the lower fixed shaft II is located directly below the central fixed shaft, a limiting shaft is fixedly mounted on the side of the vehicle body, one end of the hydraulic cylinder body is movably sleeved with the limiting shaft, and one end of the hydraulic cylinder piston shaft is movably sleeved with the lower fixed shaft II.

[0013] Furthermore, the top of the positioning stopper is movably connected to the bottom of the load plate, and the positioning stopper is located outside the supporting stopper.

[0014] Furthermore, a linkage pull plate is movably sleeved on the lower fixed shaft II connected to the hydraulic cylinder, and the other end of the linkage pull plate is movably sleeved on the lower fixed shaft II away from the side of the hydraulic cylinder.

[0015] Beneficial effects of the present invention:

[0016] 1. The present application provides a large-tonnage flatbed lifting truck. Through the setting of a transmission support device, when the hydraulic cylinder drives the load flatbed to lift the loaded goods, the load flatbed can be pushed to move obliquely upward away from the side of the vehicle body, so that the upper fixed axis I and the linkage rotating plate I can rotate with the lower fixed axis I as the axis, thereby achieving the effect of controlling the lifting and lowering of the load flatbed to transport the goods. Compared with the existing method of transporting goods by forks, it can also transport large-tonnage goods without the risk of goods tipping over, thereby improving safety and being able to transport large-tonnage goods for short distances.

[0017] 2. Through the setting of the transmission support device, after the aerial linkage turntable I rotates to a vertical state, the linkage turntable I itself is also used to support the moving crossbeam and the load plate as a whole. Compared with the existing flatbed lifting truck, the load plate is driven to rise by the hydraulic cylinder, and the load plate is supported by the hydraulic cylinder itself. This prevents the load plate from being loaded with large-tonnage goods. After the large-tonnage goods on the load plate are lifted, the goods are moved to the shelf and moved. The vibration may cause the oil cylinder to shake, causing additional pressure and wear on the structure and seals of the hydraulic cylinder, thereby improving the service life of the hydraulic cylinder and the safety of large-tonnage cargo handling.

[0018] 3. Through the structural design of the obtuse triangle plate in the setting of the transmission support device, during the lifting process of the load-bearing flatbed cargo, the load is always supported by the central fixed axis rather than the hydraulic cylinder. In this way, when lifting large-tonnage cargo, the problem of easy wear of the hydraulic cylinder piston shaft due to the inclined setting of the hydraulic cylinder piston shaft and the need to move the large-tonnage cargo can be avoided, which can further improve the service life.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] Embodiment 1

[0029] See also Figure 1-Figure 3 A large-tonnage flatbed lifting truck comprises a vehicle body 1, two positioning beams 2 are fixedly installed on one side of the vehicle body 1, and the two positioning beams 2 are respectively arranged at both ends of the side of the vehicle body 1, a plurality of equidistantly arranged reinforcing beams 3 are fixedly installed between the two positioning beams 2, and the number of the reinforcing beams 3 is not less than two, and the overall strength of the positioning beams 2 and the reinforcing beams 3 is improved by connecting the plurality of reinforcing beams 3 between the two positioning beams 2, transmission support devices are installed on the two positioning beams 2, and the number of the transmission support devices on each positioning beam 2 is not less than two, and a moving beam 4 is fixedly installed on the top of the transmission support device on each positioning beam 2, and a load plate 5 is fixedly installed on the top of the two moving beams 4, and the goods are placed on the load plate 5, and are pushed by the vehicle body 1 to transport the goods.

[0030] A number of equidistantly arranged reinforcement plates 6 are fixedly installed between the two moving beams 4, and the top of the reinforcement plate 6 is connected to the bottom of the load plate 5. By arranging a number of reinforcement plates 6 between the two moving beams 4 and below the load plate 5, the overall stability of the moving beams 4 and the load plate 5 is improved to ensure that large tonnage of goods can be placed on the load plate 5. Two positioning members 7 are fixedly installed on one of the reinforcement beams 3, and the two positioning members 7 are respectively arranged at both ends of the reinforcement beam 3. A hydraulic cylinder 8 is provided between the positioning member 7 and the reinforcement plate 6. The piston shaft is driven by the hydraulic cylinder 8 to push the reinforcement plate 6 to move obliquely upward away from the side of the vehicle body 1, thereby pushing the moving beam 4 and the load plate 5 to move upward as a whole for loading or unloading.

[0031] The transmission support device includes a lower fixed shaft Ⅰ9, which is fixedly mounted on the positioning beam 2. A linkage rotating plate Ⅰ10 is movably mounted on the lower fixed shaft Ⅰ9. An upper fixed shaft Ⅰ11 is movably mounted on the end of the linkage rotating plate Ⅰ10 away from the lower fixed shaft Ⅰ9. The upper fixed shaft Ⅰ11 is mounted on the moving beam 4. The piston shaft is driven to move by the hydraulic cylinder 8, which can push the reinforcement plate 6, the moving beam 4 and the load plate 5 as a whole to move obliquely upward away from the side of the vehicle body 1, so that the upper fixed shaft Ⅰ11 and the linkage rotating plate Ⅰ10 rotate around the lower fixed shaft Ⅰ9 as the axis, thereby achieving the effect of controlling the lifting and lowering of the load plate 5, so as to transport goods. Compared with the existing method of transporting goods by forks, it can also transport large tonnage of goods without being easy to The situation of cargo tipping over occurs, thereby improving safety and being able to transport large-tonnage cargo for short-distance transportation. After the aerial linkage turntable Ⅰ10 is rotated to a vertical state, the linkage turntable Ⅰ10 itself is also used to support the moving crossbeam 4 and the load plate 5 as a whole. Compared with the existing flatbed lift truck that drives the load plate 5 to rise through the hydraulic cylinder, the hydraulic cylinder itself supports the load plate 5. When the load plate 5 is loaded with large-tonnage cargo, after the large-tonnage cargo on the load plate 5 is controlled to be lifted, the cargo is transported to the shelf and moved. The vibration may cause the oil cylinder to shake, causing additional pressure and wear on the structure and seals of the hydraulic cylinder, thereby increasing the service life of the hydraulic cylinder.

[0032] A support block 12 located on one side of the lower fixed axis Ⅰ9 is fixedly installed on the positioning beam 2, and the top of the support block 12 is movably connected to the bottom of the moving beam 4. When the load plate 5 drops to the lowest point, the moving beam 4 and the load plate 5 are supported by the support block 12 on the positioning beam 2, so that the vehicle body 1 pushes the load plate 5 carrying large tonnage of goods for short-distance transportation. In addition, by setting the support block 12 on one side of the lower fixed axis Ⅰ9, when the linkage rotating plate Ⅰ10 rotates to a vertical state, the side of the support block 12 just fits with the side of the linkage rotating plate Ⅰ10, thereby limiting the linkage rotating plate Ⅰ10 to prevent the linkage rotating plate Ⅰ10 from rotating excessively. At the same time, with the support of the hydraulic cylinder 8, the linkage rotating plate Ⅰ10 can be stably maintained in a vertical state, thereby providing support.

[0033] Embodiment 2

[0034] See also Figure 4On the basis of the first embodiment, the difference from the first embodiment is that the installation position of the hydraulic cylinder 8 is different, and the transmission support device includes a plurality of groups of positioning blocks 13, the number of the groups of positioning blocks 13 is not less than two, and the number of each group of positioning blocks 13 is two, each group of positioning blocks 13 is respectively fixedly mounted on two positioning beams 2, the top of the positioning block 13 is movably connected to the bottom of the load plate 5, and the positioning block 13 is located on the outside of the support block 12, when the load plate 5 drops to the lowest point, the positioning block 13 also directly contacts the load plate 5 The supporting block 12 on the positioning beam 2 is used to support the movable beam 4, which further improves the supporting effect. A central fixed axis 14 is fixedly installed between the two positioning blocks 13 of each group, and the central fixed axis 14 is arranged in the middle of the positioning block 13. A linkage rotating plate Ⅱ 15 is movably mounted on the central fixed axis 14. The front of the linkage rotating plate Ⅱ 15 is in the shape of an obtuse triangle, and the central fixed axis 14 is close to the obtuse end of the linkage rotating plate Ⅱ 15. One of the acute ends of the linkage rotating plate Ⅱ 15 is movably mounted with an upper fixed axis Ⅱ 16. Ⅱ16 is fixedly installed on the moving crossbeam 4, and the other acute angle end of the linkage rotating plate Ⅱ15 is movably sleeved with a lower fixed shaft Ⅱ17, and when the load plate 5 is lowered to the lowest point, the lower fixed shaft Ⅱ17 is located directly below the central fixed shaft 14, and a limiting shaft 18 is fixedly installed on the side of the vehicle body 1, and a hydraulic cylinder 8 is arranged between the limiting shaft 18 and the lower fixed shaft Ⅱ17, that is, one end of the cylinder body of the hydraulic cylinder 8 is movably sleeved with the limiting shaft 18, and one end of the piston shaft of the hydraulic cylinder 8 is movably sleeved with the lower fixed shaft Ⅱ17, and the lower fixed shaft Ⅱ17 connected to the hydraulic cylinder 8 is also movably sleeved. A linkage pull plate 19 is sleeved, and the other end of the linkage pull plate 19 is movably sleeved with the lower fixed shaft Ⅱ17 away from the side of the hydraulic cylinder 8. When the hydraulic cylinder 8 drives the piston shaft to recover and move, the piston shaft of the hydraulic cylinder 8 pulls the lower fixed shaft Ⅱ17 to move, so that the linkage rotating plate Ⅱ15 near the hydraulic cylinder 8 rotates with the central fixed shaft 14 as the axis. Through the linkage of the linkage pull plate 19, the linkage rotating plate Ⅱ15 away from the side of the hydraulic cylinder 8 rotates synchronously, so that the movable crossbeam 4 and the load plate 5 move obliquely upward away from the vehicle body 1, thereby achieving a lifting effect.

[0035] Compared with the first embodiment, during the lifting process of the load plate 5 loaded with goods, the load is always supported by the central fixed shaft 14 instead of the hydraulic cylinder 8. In this way, when lifting large-tonnage goods, the problem of easy wear of the piston shaft of the hydraulic cylinder 8 due to the inclined setting of the piston shaft of the hydraulic cylinder 8 and the need to move the large-tonnage goods can be avoided, and the service life can be further improved.
