Description

Technical Field

[0001] This utility model belongs to the technical field of handling vehicle equipment, specifically relating to a simple and easy-to-maintain handling vehicle. Background Technology

[0002] In modern logistics, warehousing, and various industrial production scenarios, material handling vehicles are critical material handling equipment, and their performance directly affects operational efficiency and costs. In existing technologies, the battery and hydraulic station layout of traditional material handling vehicles is often inefficient. In most cases, the hydraulic station and battery are mixed in the same cavity, which can easily lead to hydraulic oil leakage contaminating the battery, affecting its lifespan and performance. Furthermore, the two components interfere with each other, increasing the difficulty of troubleshooting. Additionally, the vehicle body of many material handling vehicles is fixed and encapsulated, making the installation locations of the battery and hydraulic station difficult to access. Once a malfunction occurs, maintenance personnel must spend a significant amount of time dismantling the complex outer casing and related components to reach the core fault point, resulting in cumbersome operations and extremely high maintenance difficulty. Summary of the Invention

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a simple and convenient transport vehicle for maintenance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a simple and convenient transport vehicle, comprising a vehicle body, a fork with load-bearing wheels on one side of the vehicle body, a drive control system on the side of the vehicle body away from the fork and the drive control system being connected to a vertically arranged operating system, a drive cover detachably mounted on the outside of the vehicle body covering the drive control system, an installation cavity inside the vehicle body, and an opening on the side of the vehicle body near the drive control system, a baffle capable of closing the installation cavity being detachably mounted at the opening of the installation cavity, and the installation cavity having a battery installation cavity for installing a lithium battery and a hydraulic station installation cavity for installing a hydraulic station, both independently arranged vertically, and a battery inlet communicating with the battery installation cavity, and the lithium battery being mounted in the battery installation cavity via a snap-fit ​​assembly. The removable drive cover facilitates quick inspection and maintenance of the drive control system. The open mounting cavity and removable baffle design make it easy to repair or replace core components such as the internal lithium battery and hydraulic station, improving maintenance convenience. The battery mounting cavity and hydraulic station mounting cavity are set up independently, realizing functional zoning and avoiding mutual interference when the two are working, resulting in a more reasonable layout. The battery installation port is located at the top of the vehicle body. Combined with the snap-fit ​​component, the installation or removal of lithium batteries can be completed without complicated tools, simplifying the battery maintenance process.

[0005] In the aforementioned simple and easy-to-maintain pallet truck, two forks are arranged parallel to each other on one side of the vehicle body, and the load-bearing wheels are respectively located at the ends of the forks furthest from the vehicle body. The design of two parallel forks can stably support the goods, distribute the weight, and prevent uneven force on a single fork from causing the goods to tilt. The load-bearing wheels at the ends of the forks can reduce frictional resistance when the forks are inserted into the bottom of the goods or during movement, facilitating flexible insertion of the forks under the goods and improving the smoothness of the handling operation.

[0006] In the aforementioned simple and easy-to-maintain transport vehicle, the length of the vehicle body gradually increases from the upper end to the lower end. The vehicle body has an outer frame on one side along its width and inclined side frames on both sides along its length. This gradual increase in length lowers the overall center of gravity, enhancing the stability of the transport vehicle during operation and reducing the risk of tipping over. The outer frame and inclined side frame structures enhance the overall rigidity of the vehicle body, while the inclined side frames distribute stress, increasing the vehicle's load-bearing capacity and extending its service life.

[0007] In the aforementioned simple and convenient transport vehicle, the baffle has oblique connecting parts at both ends, and a vehicle body fixing part is located on the side of the oblique connecting part away from the baffle. The vehicle body fixing part is parallel to the baffle, and a recess is formed between the baffle and the oblique connecting part. The oblique connecting part adapts to the oblique side frame of the vehicle body, improving the fit between the baffle and the vehicle body and ensuring the sealing of the installation cavity. The recessed design reduces material usage and the weight of the baffle, ensuring the compactness of the installation cavity, while also facilitating gripping operations during baffle installation / removal. The vehicle body fixing part is parallel to the baffle, ensuring even force distribution during bolt fixing and improving the firmness of the baffle connection.

[0008] In the aforementioned simple and convenient transport vehicle, a baffle fixing part is provided on the side of the inclined side frame away from the outer frame. The baffle fixing part is arranged along the opening direction of the mounting cavity, and the baffle is located within the mounting cavity. The baffle fixing part corresponds one-to-one with the vehicle body fixing part, and the baffle fixing part and the vehicle body fixing part are connected by several fixing bolts. The one-to-one correspondence between the baffle fixing part and the vehicle body fixing part achieves precise positioning, simplifies the baffle installation process, and the baffle fixing part's arrangement along the opening direction facilitates bolt tightening, improving baffle disassembly efficiency. The baffle's location within the mounting cavity saves external space, and the bolt connection method ensures both reliable sealing and convenient quick opening for later maintenance.

[0009] In the aforementioned simple and convenient transport vehicle, a horizontally arranged mounting plate is provided within the mounting cavity. Both ends of the mounting plate are connected to the inclined side frame, and one side of the mounting plate is connected to the outer frame. The battery mounting cavity is located above the mounting plate, and the hydraulic station mounting cavity is located below the mounting plate. The horizontal mounting plate connects the inclined side frame and the outer frame, further enhancing the structural strength of the vehicle body and preventing cavity deformation. The mounting plate divides the cavity vertically, clearly defining the mounting areas for the lithium battery and the hydraulic station, resulting in a clear internal layout and facilitating individual repair of any component.

[0010] In the aforementioned simple and convenient transport vehicle, the mounting plate has upwardly bent portions at both ends on the side away from the outer frame, with a notch between the two bent portions. The inner upper side of the mounting plate also has a battery fixing portion corresponding to the notch. The bent portions of the mounting plate enhance its resistance to deformation and improve structural stability. The notch between the two bent portions corresponds to the battery insertion port, providing guiding space for the insertion / removal of the lithium battery and facilitating battery positioning. The battery fixing portion, in conjunction with the snap-fit ​​assembly, further strengthens the installation stability of the lithium battery.

[0011] In the aforementioned simple and convenient transport vehicle, the snap-fit ​​assembly includes snap-fit ​​plates disposed at both ends of the battery fixing part. Several snap-fit ​​blocks are disposed on the side of the battery fixing part away from the notch. Both the snap-fit ​​plates and snap-fit ​​blocks are vertically arranged. The upper end of the snap-fit ​​plate has an inclined guide portion, and the upper end of the snap-fit ​​block has an arc-shaped portion. A snap-fit ​​groove for inserting the lower end of the lithium battery is formed between the snap-fit ​​blocks, snap-fit ​​plates, and the bending portion. The snap-fit ​​groove provides a precise installation position for the lower end of the lithium battery, enabling rapid positioning without complex fixing steps. The inclined guide portion of the snap-fit ​​plate and the arc-shaped portion of the snap-fit ​​block reduce resistance during lithium battery insertion, providing guidance and simplifying installation. The enclosed structure formed by the snap-fit ​​plate, snap-fit ​​blocks, and bending portion effectively restricts lithium battery movement, ensuring secure installation. Disassembly is convenient; simply remove the battery upwards.

[0012] In the aforementioned simple and convenient transport vehicle, a hydraulic station mounting cavity is equipped with a hydraulic station fixing seat. The hydraulic station is connected to the hydraulic station fixing seat, and the upper end of the hydraulic station fixing seat is connected to the mounting plate via several fixing screws. The hydraulic station fixing seat enhances the stability of the hydraulic station installation, preventing displacement due to vibration during operation. The hydraulic station fixing seat is connected to the mounting plate via screws, making disassembly convenient and facilitating the maintenance and replacement of the hydraulic station. Furthermore, the fixing method is reliable, ensuring stable operation of the hydraulic system.

[0013] In the aforementioned simple and convenient transport vehicle, the operating system has a handle rod with an operating handle at the upper end. The drive control system has a drive assembly connected to the lower end of the handle rod, and the upper end of the drive assembly has a hydraulic rod fixed to the vehicle body, which is connected to a hydraulic station.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. The device adopts a modular and detachable design. The drive cover is detachable, the baffle of the mounting cavity is detachable, and the lithium battery can be quickly installed and removed via a snap-fit ​​assembly. The drive control system, hydraulic station, and battery can all be exposed without complicated disassembly. During maintenance, there is no need to disassemble unrelated structures, which significantly shortens maintenance time.

[0016] 2. The device makes efficient use of its internal space and features an independent partitioned layout. The mounting plate divides the mounting cavity into a battery cavity and a hydraulic station cavity, ensuring that the two working environments do not interfere with each other. During maintenance, a single component can be operated on, reducing cross-interference and the risk of misoperation, and also making the vehicle body structure compact.

[0017] 3. The vehicle body of the device forms a rigid support structure through the outer frame and the inclined side frame. The inclined side frame distributes the force, and the shape of the length gradually increases from the top to the bottom lowers the overall center of gravity, reducing the risk of tipping over when handling goods. The mounting plate connects the two side frames, further enhancing the stability of the cavity structure and preventing deformation under load. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-5 As shown, a simple and convenient transport vehicle includes a vehicle body 1. A fork 11 with load-bearing wheels is provided on one side of the vehicle body 1. A drive control system 12 is provided on the side of the vehicle body 1 away from the fork 11, and the drive control system 12 is connected to a vertically arranged operating system 13. A drive cover 14 is detachably provided on the outside of the vehicle body 1 and covers the outside of the drive control system 12. The vehicle body 1 has an installation cavity 15, and the side of the vehicle body 1 near the drive control system 12 has an opening. A baffle 2 that can close the installation cavity 15 is detachably provided at the opening of the installation cavity 15. The installation cavity 15 has a battery installation cavity 16 for installing a lithium battery 161 and a hydraulic station installation cavity 17 for installing a hydraulic station 171, which are independently arranged at the top and bottom. The upper end of the vehicle body 1 has a battery inlet 18 that communicates with the battery installation cavity 16, and the lithium battery 161 is installed in the battery installation cavity 16 through a snap-fit ​​assembly 3. The drive cover 14 is designed to be detachable, which facilitates quick maintenance of the drive control system 12. The design of the open mounting cavity 15 and the detachable baffle 2 makes it easy to repair or replace the core components such as the internal lithium battery 161 and hydraulic station 171, improving maintenance convenience. The battery mounting cavity 16 and the hydraulic station mounting cavity 17 are set up independently, realizing functional zoning and avoiding mutual interference when the two are working, resulting in a more reasonable layout. The upper part of the vehicle body 1 is provided with a battery loading port 18. Combined with the snap-fit ​​component 3, the installation or removal of the lithium battery 161 can be completed without complicated tools, simplifying the battery maintenance process.

[0026] like Figure 1 As shown, there are two forks 11 arranged parallel to each other on one side of the vehicle body 1, and the load-bearing wheels are respectively located at the ends of the forks 11 away from the vehicle body 1. The design of two parallel forks 11 can stably support the goods, distribute the weight, and avoid the goods tilting due to uneven force on a single fork. The load-bearing wheels at the ends of the forks 11 can reduce the frictional resistance when the forks 11 are inserted into the bottom of the goods or when moving, making it easier for the forks to be inserted flexibly under the goods and improving the smoothness of the handling operation.

[0027] like Figure 2 As shown, the length of the vehicle body 1 gradually increases from the upper end to the lower end. The vehicle body 1 has an outer frame 4 on one side along its width and inclined side frames 41 on both sides along its length. The gradual increase in length from the upper end to the lower end of the vehicle body 1 lowers the overall center of gravity, enhances the stability of the transport vehicle during operation, and reduces the risk of tipping over. The structure of the outer frame 4 and the inclined side frames 41 enhances the overall rigidity of the vehicle body 1, while the inclined side frames 41 distribute the stress, increasing the load-bearing capacity of the vehicle body 1 and extending its service life.

[0028] Combination Figure 2 and Figure 4 As shown, the baffle 2 has oblique connecting portions 21 at both ends. A vehicle body fixing portion 22 is located on the side of the oblique connecting portion 21 away from the baffle 2. The vehicle body fixing portion 22 is parallel to the baffle 2, and a recess 23 is formed between the baffle 2 and the oblique connecting portion 21. The oblique connecting portion 21 is adapted to the oblique side frame 41 of the vehicle body 1, improving the fit between the baffle 2 and the vehicle body 1 and ensuring the sealing of the mounting cavity 15. The recess 23 design reduces material usage and the weight of the baffle 2, ensuring the compactness of the mounting cavity 15, while also facilitating the gripping operation when installing / removing the baffle 2. The vehicle body fixing portion 22 is parallel to the baffle 2, ensuring uniform force distribution during bolt fixing and improving the firmness of the baffle 2 connection.

[0029] The inclined side frame 41 has a baffle fixing part 42 on the side away from the outer frame 4. The baffle fixing part 42 is arranged along the opening direction of the mounting cavity 15. The baffle 2 is located inside the mounting cavity 15. The baffle fixing part 42 corresponds one-to-one with the vehicle body fixing part 22, and the baffle fixing part 42 and the vehicle body fixing part 22 are connected by several fixing bolts. The one-to-one correspondence between the baffle fixing part 42 and the vehicle body fixing part 22 achieves precise positioning and simplifies the installation process of the baffle 2. The baffle fixing part 42 is arranged along the opening direction, which facilitates the tightening of bolts and improves the disassembly efficiency of the baffle 2. The baffle 2 is located inside the mounting cavity 15, saving external space. The bolt connection method ensures both sealing reliability and facilitates quick opening during later maintenance.

[0030] like Figure 3 As shown, the mounting cavity 15 is provided with a horizontally arranged mounting plate 43. Both ends of the mounting plate 43 are connected to the inclined side frame 41, and one side of the mounting plate 43 is connected to the outer frame 4. The battery mounting cavity 16 is located above the mounting plate 43, and the hydraulic station mounting cavity 17 is located below the mounting plate 43. The horizontal mounting plate 43 connects the inclined side frame 41 and the outer frame 4, further enhancing the structural strength of the vehicle body 1 and preventing cavity deformation. The mounting plate 43 divides the cavity vertically, clearly defining the mounting areas of the lithium battery 161 and the hydraulic station 171, making the internal layout clear and facilitating individual repair of any component.

[0031] like Figure 5 As shown, the mounting plate 43 has upwardly bent portions 44 at both ends on the side away from the outer frame 4, with a notch 45 between the two bent portions 44, and a battery fixing portion 46 corresponding to the notch 45 is provided on the inner side of the upper end of the mounting plate 43. The bent portions 44 of the mounting plate 43 can enhance its own resistance to deformation and improve structural stability. The notch 45 between the two bent portions 44 corresponds to the battery inlet 18, providing guiding space for the insertion / removal of the lithium battery 161 and facilitating battery positioning. The battery fixing portion 46, in conjunction with the snap-fit ​​assembly 3, further enhances the installation stability of the lithium battery 161.

[0032] The snap-fit ​​assembly 3 includes snap-fit ​​plates 31 disposed at both ends of the battery fixing part 46. Several snap-fit ​​blocks 32 are disposed on the side of the battery fixing part 46 away from the notch 45. Both the snap-fit ​​plates 31 and snap-fit ​​blocks 32 are vertically arranged. The upper end of the snap-fit ​​plate 31 has an inclined guide portion 33, and the upper end of the snap-fit ​​block 32 has an arc-shaped portion 34. A snap-fit ​​groove 35 for inserting the lower end of the lithium battery 161 is formed between the snap-fit ​​blocks 32, the snap-fit ​​plates 31, and the bending portion 44. The snap-fit ​​groove 35 provides a precise installation position for the lower end of the lithium battery 161, enabling rapid positioning without complex fixing steps. The inclined guide portion 33 of the snap-fit ​​plate 31 and the arc-shaped portion 34 of the snap-fit ​​block 32 reduce the resistance when inserting the lithium battery 161, providing guidance and simplifying the installation operation. The enclosed structure formed by the snap-fit ​​plate 31, the snap-fit ​​blocks 32, and the bending portion 44 effectively restricts the shaking of the lithium battery 161, ensuring installation stability. Disassembly is convenient; simply remove the battery upwards.

[0033] like Figure 3 As shown, a hydraulic station mounting cavity 17 is equipped with a hydraulic station mounting base 5. The hydraulic station 171 is connected to the hydraulic station mounting base 5, and the upper end of the hydraulic station mounting base 5 is connected to the mounting plate 43 by several fixing screws. The hydraulic station mounting base 5 can enhance the stability of the hydraulic station 171 during installation and prevent displacement due to vibration during operation. The hydraulic station mounting base 5 is connected to the mounting plate 43 by screws, which is convenient for disassembly, facilitating the maintenance and replacement of the hydraulic station 171. The fixing method is reliable, ensuring the stable operation of the hydraulic system.

[0034] like Figure 1 As shown, the operating system 13 has a handle 51, and the upper end of the handle 51 is provided with an operating handle 52. The drive control system 12 has a drive assembly 53 connected to the lower end of the handle 51. The upper end of the drive assembly 53 is provided with a hydraulic rod 54 fixed to the vehicle body 1, and the hydraulic rod 54 is connected to the hydraulic station 171.

[0035] The principle of this embodiment is as follows:

[0036] The outer frame 4 of the vehicle body 1 and the inclined side frames 41 on both sides along the length direction serve as the core support structure. They are welded together to form an integral frame, providing an installation reference for all subsequent components. The rigid design of the vehicle body 1 ensures the overall load-bearing capacity, and the inclined structure distributes the force to prevent deformation due to load after assembly. The hydraulic station mounting base 5 is connected to the lower end face of the mounting plate 43 by several fixing screws to ensure the stability of the hydraulic station mounting base 5. Then, the hydraulic station 171 is fixed to the hydraulic station mounting base 5 with bolts. The supporting effect of the hydraulic station mounting base 5 prevents the hydraulic station 171 from shifting due to vibration during operation. At the same time, the mounting plate 43 isolates the hydraulic station 171 from the battery above to prevent oil contamination. The snap-fit ​​assembly 3 is set on the battery fixing part 46 of the mounting plate 43. The snap-fit ​​plate 31 is located at both ends of the battery fixing part 46, and the snap-fit ​​block 32 is located at the far end. On the side away from the notch 45, the three components together with the bend 44 form a snap-fit ​​groove 35. The lithium battery 161 is inserted from the battery inlet 18 at the top of the vehicle body 1. Guided by the inclined guide part 33 of the snap-fit ​​plate 32 and the arc-shaped part 34 of the snap-fit ​​block 32, the lower end of the lithium battery 161 is precisely inserted into the snap-fit ​​groove 35. The surrounding force of the snap-fit ​​structure is used to achieve boltless fixation, which simplifies the installation and ensures stability. The baffle 2 is inserted from the opening of the mounting cavity 15. The inclined connecting parts 21 at both ends of the baffle 2 fit with the inclined side frame 41 of the vehicle body 1. The vehicle body fixing part 22 is aligned with the baffle fixing part 42 on the inclined side frame 41. The connection is achieved by several fixing bolts passing through the two. The baffle 2 is located in the mounting cavity, which not only seals the cavity, but also makes the cavity interior compact through the recess 23, ensuring the stability of the lithium battery 161 and the hydraulic station 171.
