Description

Technical Field

[0001] This utility model relates to the field of forklift technology, specifically to a forklift that can be used with double-sided pallets. Background Technology

[0002] Pallets are widely used as common container units in cargo transportation and loading / unloading operations.

[0003] Double-sided pallets and pallets with crossbeams underneath are increasingly used due to their high load-bearing capacity and stability. However, existing truck-mounted forklifts have several problems in use. Due to limitations in their structural design, they are difficult to adapt to double-sided pallets and pallets with crossbeams underneath. When loading and unloading these types of pallets, the forks of traditional pallet trucks cannot be inserted from the bottom sides of the pallet, thus limiting the use of traditional hydraulic forklifts. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a truck-mounted forklift that can be used with double-sided pallets, so as to solve the problem that the forks of traditional pallet trucks cannot be inserted from both sides of the bottom of the pallet, which restricts the use of traditional hydraulic forklifts.

[0005] According to an embodiment of this utility model, a forklift for use with double-sided pallets includes a mounting platform with a column on it and grooves at both ends. A support arm is slidably arranged in each groove, and a load-bearing wheel is provided at the end of each support arm away from the column. A lifting unit includes a lifting cylinder located inside the column and mounted on the mounting platform, and a lifting frame slidably arranged inside the column and connected to the output end of the lifting cylinder. An unloading unit includes a mounting frame fixedly mounted on the lifting frame and two forks slidably mounted on the mounting frame, with the two forks located between two support arms. A support unit is located at the middle position along the length of the corresponding support arm to improve the strength of the corresponding support arm.

[0006] Compared with existing technologies, this utility model has the following beneficial effects: By changing the mechanism of traditional hydraulic forklifts, widening the width of the two support arms at the bottom of the hydraulic forklift, and then placing the two forks between the two support arms, sufficient space is provided for the forks to insert into double-sided pallets; the lateral space formed by the two support arms, combined with the adjustable spacing of the forks, ensures that the forks can be smoothly inserted from the bottom of the pallet without interfering with the support arms during the insertion process, greatly improving the forklift's adaptability to double-sided pallets and ease of operation, effectively solving the problem that traditional forklifts have difficulty inserting double-sided pallets from both sides. For double-sided pallets of different specifications and pallets with crossbeams at the bottom, the operator can flexibly adjust the distance between the forks to accurately align with the fork holes on both sides of the bottom of the pallet for smooth insertion, overcoming the limitation of the fixed fork spacing of traditional forklifts, which cannot adapt to various pallets, and significantly improving the versatility and loading and unloading efficiency of forklifts.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a forklift that can be used with double-sided pallets. It includes a mounting platform 1 with a column 2 on it and grooves 11 at both ends. A support arm 4 is slidably arranged in each groove 11, and a load-bearing wheel 41 is provided at the end of each support arm 4 away from the column 2. A lifting unit includes a lifting cylinder 21 located in the column 2 and mounted on the mounting platform 1, and a lifting frame 22 slidably arranged in the column 2 and connected to the output end of the lifting cylinder 21. An unloading unit includes a mounting frame 34 fixedly mounted on the lifting frame 22, and two forks 3 slidably arranged on the mounting frame 34, with the two forks 3 located between the two support arms 4. A support unit is arranged at the middle position of the length direction of the corresponding support arm 4 to improve the strength of the corresponding support arm 4.

[0022] The detailed working process of this embodiment is as follows: two forks 3 are placed between two support arms 4 to provide sufficient space for the forks 3 to be inserted into the double-sided pallet; the lateral space formed by the two support arms 4, together with the adjustable spacing of the forks 3, can ensure that the forks 3 are smoothly inserted from the bottom of the pallet, and will not interfere with the support arms 4 during the insertion process, which greatly improves the adaptability and operational convenience of the forklift to double-sided pallets. For double-sided pallets of different specifications and pallets with crossbeams at the bottom, the operator can flexibly adjust the distance between the forks 3 to accurately align them with the fork holes on both sides of the bottom of the pallet and insert them smoothly.

[0023] The support unit provides effective support for the support arm 4, preventing it from breaking under stress. The lifting cylinder 21 and the lifting frame 22 work together to precisely control the lifting height of the forks 3. When the forks 3 are inserted from both sides of the bottom of the pallet, the height of the lifting frame 22 can be adjusted via the lifting cylinder 21 to ensure the forks 3 are accurately aligned with the pallet fork holes, smoothly completing the insertion. Simultaneously, the pallet height can be flexibly adjusted according to actual needs during handling.

[0024] like Figure 2 As shown, rolling bearings 23 are mirror-mounted on the lifting frame 22, and each rolling bearing 23 is located inside the column 2.

[0025] The detailed working process of this embodiment is as follows: With the rolling bearing 23 in place, the sliding friction between the lifting frame 22 and the column 2 is converted into rolling friction, thereby reducing friction and energy loss.

[0026] like Figure 2 As shown, the mounting bracket 34 is provided with a mounting shaft 33, and each fork 3 is provided with a mounting sleeve 31, which is fitted onto the mounting shaft 33.

[0027] The detailed working process of this embodiment is as follows: With the installation sleeve 31 set, the forks 3 can slide along the installation shaft 33 to adjust the relative distance between the two forks 3. Thus, the two forks 3 can be adjusted according to various specifications of double-sided pallets, so that the forks 3 can be accurately inserted into the fork holes on both sides of the bottom of the pallet, which greatly improves the adaptability of the forklift to different pallets.

[0028] like Figure 2 As shown, each mounting sleeve 31 is threaded with a fastening bolt 32, and each fastening bolt 32 abuts against the mounting shaft 33.

[0029] The detailed working process of this embodiment is as follows: With the fastening bolt 32 in place, after the fork 3 is adjusted to a suitable position, the fastening bolt 32 is tightened so that it abuts against the mounting shaft 33, thereby fixing it and preventing the fork 3 from shifting or shaking during the handling of goods.

[0030] like Figure 3 As shown, each support arm 4 has an operation slot 42 and a storage slot 43 at its bottom, and the operation slot 42 and the storage slot 43 are located at both ends of the corresponding support unit.

[0031] like Figure 3 As shown, each support unit includes a fixed base 63 disposed in the storage groove 43 and an intermediate wheel 61 hinged to the fixed base 63. Each support arm 4 is provided with multiple sets of limiting pins 64. A limiting slider 62 is slidably disposed inside the support arm 4. The limiting slider 62 is located between the corresponding limiting pins 64. A return spring 623 is sleeved on the limiting slider 62. One end of the return spring 623 abuts against the corresponding limiting pin 64. A first notch 621 and a second notch 622 are respectively opened at the two corners of the end of the limiting pin 64 away from the return spring 623. The limiting slider 62 abuts against the intermediate wheel 61 under the elastic force of the return spring 623. A handle 65 is provided at the end of the limiting slider 62 away from the first notch 621. The handle 65 is located in the operating groove 42.

[0032] The detailed working process of this embodiment is as follows: The fixed seat 63 is set in the storage groove 43, providing a hinge base for the intermediate wheel 61; the intermediate wheel 61 is hinged to the fixed seat 63 and can rotate flexibly. The limiting slider 62 is located between multiple sets of limiting pins 64 and can slide within the support arm 4. One end of the return spring 623 sleeved on it abuts against the limiting pin 64. Using the spring force, the limiting slider 62 abuts against the intermediate wheel 61 when no external force is applied. The first notch 621 and the second notch 622 on the limiting pin 64, together with the limiting shaft 611 on the limiting slider 62 and the intermediate wheel 61, realize the locking of the intermediate wheel 61 in the extended or retracted state. The handle 65 is set at the end of the limiting slider 62 away from the first notch 621 and located in the operating groove 42, which facilitates the operator to control the sliding of the limiting slider 62 and thus operate the intermediate wheel 61.

[0033] like Figure 3 As shown, each intermediate wheel 61 includes a bracket 612 hinged to a fixed seat 63 and a roller 613 rolling on the bracket 612. A limit shaft 611 is provided at one end of the bracket 612 away from the roller 613, and the limit shaft 611 abuts against the first notch 621 or the second notch 622.

[0034] The detailed working process of this embodiment is as follows: The setting of the limiting shaft 611 provides a key connection point for the state control of the intermediate wheel 61. It abuts against the first notch 621 or the second notch 622 on the limiting slider 62 to lock the intermediate wheel 61 in the extended or retracted state. When the intermediate wheel 61 is extended, it can provide support for the support arm 4 and improve its strength. When it is retracted, it can improve the forklift's flexibility and have better passability to adapt to more complex working conditions such as climbing hills and off-road driving.

[0035] When the intermediate wheel 61 is needed, the operator pulls the handle 65, causing the limiting slider 62 to move against the elastic force of the return spring 623. The limiting shaft 611 is released from the limitation of the limiting slider 62, and the intermediate wheel 61 rotates around the fixed seat 63 under the action of gravity and extends out of the support arm 4. At this time, the limiting shaft 611 falls into the first notch 621 of the limiting slider 62, fixing the intermediate wheel 61 in the extended state. When the intermediate wheel 61 is no longer needed, the operator pulls the handle 65 again, causing the limiting slider 62 to move, the limiting shaft 611 to disengage from the notch, and the intermediate wheel 61 rotates back into the storage groove 43 in the support arm 4, completing the storage process.

[0036] like Figure 4 As shown, an operating handle 5 is also rotatably mounted on the mounting platform 1, and a directional wheel 51 is mounted at the bottom of the operating handle 5.

[0037] The detailed working process of this embodiment is as follows: With the operation handle 5 set, the steering wheel 51 can be controlled, thereby controlling the direction of the forklift.

[0038] like Figure 2 As shown, a protective cover 12 is installed on the mounting platform 1.

[0039] The detailed working process of this embodiment is as follows: The function of the protective cover 12 is to protect the various components on the mounting platform 1.
