Description

Technical Field

[0001] This utility model relates to the field of intelligent logistics equipment technology, specifically a new type of forklift working device and forklift with damping adjustment. Background Technology

[0002] A forklift is an industrial handling vehicle primarily used for loading, unloading, stacking, and short-distance transport of palletized or other goods. It is widely used in warehousing, logistics, manufacturing, ports, airports, and other facilities, and is an indispensable piece of equipment in modern logistics and warehouse management.

[0003] In order to ensure the stability and safety of goods and improve the operating efficiency of forklifts, it is especially important to keep the loading attachments level during forklift use, so as to prevent the goods from slipping due to the shift of the center of gravity during handling.

[0004] In the prior art, Chinese utility model patent application number 201910551372.6 discloses a forklift and its mast. The forklift mast includes a mast body, forks, a lifting mechanism, and a tilting mechanism. The forks have a leveling mechanism for adjusting the angle of the loading attachment, ensuring that the loading surface of the loading attachment remains horizontal when the mast body is tilted. To maintain a horizontal loading surface during operation, the entire mast body needs to be tilted, which is a passive adjustment of the loading attachment's levelness. Furthermore, during use, the tilted mast body can easily cause the forklift to tip over, leading to vehicle damage and other adverse effects, thus impacting the user experience and hindering the market promotion and application of this forklift.

Near the bottom of the fork carriage and the loading attachment, they are rotatably connected by a pivot. The fork carriage and the top of the loading attachment are connected by the damping mechanism. By adjusting the load on the two forks, the loading attachment rotates clockwise or counterclockwise relative to the fork carriage, thereby adjusting the damping mechanism so that the loading surfaces of the two forks are on the same plane and parallel to the road surface.

[0015] As a preferred embodiment of this utility model, the lifting mechanism includes a lifting drive component and a lifting transmission component.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0026] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] In the current technology, if the loading surface of a forklift is to remain level during operation, the entire mast body needs to be tilted. This is a passive adjustment of the level of the loading attachment. Furthermore, during use, the tilt of the mast body can easily cause the forklift to tip over, resulting in vehicle damage and other adverse effects. This negatively impacts the user experience and hinders the promotion and application of such forklifts in the market.

[0029] To solve the above technical problems, such as Figures 1 to 5As shown, a novel forklift working device with damping adjustment mainly consists of a mast body 1, a lifting mechanism 2, a fork carriage 3, and a loading attachment 4. The mast body 1 is mounted on the forklift frame. In the entire lifting mechanism of the forklift, the mast body 1 is the core component of the entire lifting system. Its main function is to support and guide the lifting movement of the forks 6, while providing the forklift with the necessary structural strength and stability. The lifting mechanism 2 is installed at the mast body 1 and drives the fork carriage 3 and the loading attachment 4 to move up and down, simultaneously lifting and lowering the forks 6. The fork carriage 3 is slidably connected to the mast body 1 and located between the mast body 1 and the storage attachment 4. The fork 6 is mounted on the storage attachment 4. Since the storage attachment 4 is connected to the fork carriage 3 and the fork carriage 3 is slidably mounted on the mast body 1, the lifting mechanism 2 drives the fork carriage 3 and simultaneously drives the storage attachment 4 and the fork 6 to rise and fall in the vertical or vertical direction of the mast body 1.

[0030] To ensure that the forklift in this embodiment maintains a horizontal position on the loading surface 6-1 of the forks 6 under bumpy conditions and without tilting the mast body 1, a damping mechanism 5 is also provided in the novel forklift working device of this embodiment. This mechanism is rotatably connected to the bottom of the fork carriage 3 and the loading attachment 4 via a pivot 8, and to the top of the fork carriage 3 and the loading attachment 4 via the damping mechanism 5. When encountering bumpy conditions, the center of gravity of the goods placed on the forks 6 may shift, affecting the stability of the goods. In this embodiment, by using the damping mechanism 5, the damping structure 5 can be passively adjusted according to the load of the goods on the forks 6. Specifically, the damping mechanism 5 in this embodiment is a pair of monotube shock absorbers 5-1 symmetrically arranged along the central axis of the loading attachment 4. The monotube shock absorbers 5-1 achieve passive adjustment through internal damping oil and high-pressure nitrogen. During use, the single-tube shock absorber 5-1 automatically adjusts according to the different weights on the two forks 6. If the weight on the left fork 6 is greater than that on the right fork 6, the loading attachment 4 rotates counterclockwise under the influence of the weight on the left fork 6, compressing the left single-tube shock absorber 5-1 and extending the right single-tube shock absorber 5-1, thus changing the position of the load's center of gravity and achieving dynamic balance. Similarly, if the weight on the right fork 6 is greater than that on the left fork 6, the loading attachment 4 rotates clockwise under the influence of the weight on the right fork 6, compressing the right single-tube shock absorber 5-1 and extending the left single-tube shock absorber 5-1, thus changing the position of the load's center of gravity and achieving dynamic balance. Throughout this process, only the forks 6 follow the loading attachment 4; there is no need to tilt the mast body, effectively ensuring the stability of the forklift during operation.

[0031] During lifting, the single-tube shock absorber 5-1 can effectively suppress the vibration and impact of the fork carriage 3, the loading attachment 4, and the forks 6, ensuring the stability of the goods during lifting. The symmetrically arranged single-tube shock absorbers 5-1 can balance the forces on both sides, preventing the loading attachment 4 from tilting due to unilateral vibration or impact, thereby reducing the swaying of the goods and improving the safety and reliability of operation.

[0032] To facilitate the installation of the single-tube shock absorber 5-1, in this embodiment, a pair of mounting seats 3-1 are provided on the top of the fork carriage 3. Correspondingly, a pair of connecting seats 4-1 are provided on the top of the loading attachment 4. A single single-tube shock absorber 5-1 is connected between the mounting seat 3-1 and the connecting seat 4-1. That is, by installing one end of the single-tube shock absorber 5-1 on the mounting seat 3-1 of the fork carriage 3 and the other end of the single-tube shock absorber 5-1 on the mounting seat 3-1 of the loading attachment 4, the loading attachment 4 is rotated relative to the fork carriage 3 according to the different weights borne by the two forks 6. The position of the loading attachment 4 is fixed by the single-tube shock absorber 5-1, so that the loading surface 6-1 of the forks 6 is on the same plane and the loading surface 6-1 can be kept parallel to the road surface on which the vehicle travels, thereby ensuring the stability of the goods.

[0033] To further ensure the stability of the forks 6 and the storage attachment 4 during angle adjustment, the forks 6 and the storage attachment 4 are connected by a limiting connector 7. Specifically, the limiting connector 7 can be a simple, economical, and practical pin. When the weights on the two forks 6 are different, the storage attachment 4 will rotate relative to the shelf 3, thereby causing the forks 6 mounted on the storage attachment 4 to adjust up and down. Specifically, the storage attachment 4 has mounting holes adapted to the limiting connector 7, and the pin can slide up and down within the mounting holes under the action of the single-tube shock absorber 5-1.

[0034] To facilitate the installation of the fork 6 and reduce installation difficulty, the aforementioned storage attachment 4 has a hook part 4-2. The hook part 6-2 of the fork 6 is used to hook onto the hook part 4-2. The hook part 4-2 and the main body of the storage attachment 4 form a mounting groove 4-4. The aforementioned limiting connector 7 passes through the hook part 6-2 of the fork 6 and is located in the mounting sliding hole in the mounting groove 4-4, so as to adaptively adjust the loading surface 6-1 of the fork 6 to keep it in a horizontal state, thereby ensuring the stability of the goods placed on it and reducing the probability of the goods slipping. To further ensure the stability of the forks 6 during installation, the bottom of the aforementioned mounting attachment 4 also has a connecting portion 4-3. Correspondingly, the forks 6 have an abutting portion 6-3 that matches the connecting portion 4-3. The connecting portion 4-3 and the abutting portion 6-3 are hooked together. Since it is difficult to remove the forks 6 from the front of the forklift (i.e., the side where they are installed), the forks 6 need to be installed from the side of the forklift. Specifically, they are installed along the length of the mounting groove 4-4, and then the forks 6 are pushed towards the central axis of the forklift until they reach the desired installation position. Then, the limiting connector 7 is passed through the hook portion 6-2 of the forks 6 and positioned within the mounting sliding hole in the mounting groove 4-4. The forks 6 are installed using a simultaneous top and bottom positioning method, which reduces installation difficulty. Furthermore, the hanging method allows for single-person operation, reducing labor costs and preventing the forks 6 from detaching from the forklift body, thus ensuring the forklift's performance.

[0035] To ensure that the weight of the fork carriage 3 and the loading attachment 4 is evenly distributed on both sides when carrying goods, thereby guaranteeing the even distribution of the weight of the forks 6, both the fork carriage 3 and the loading attachment 4 in this embodiment are axisymmetric. This axisymmetric design effectively reduces instability of the center of gravity caused by load shifting, thus improving the overall stability of the forklift during handling. The symmetrical structure also better resists lateral forces and vibrations, reducing swaying of the fork carriage 3 and goods during lifting or traveling, ensuring the safety of the goods and the smoothness of operation.

[0036] To maximize the utilization of the forklift in this embodiment and meet different storage height requirements, the mast body 1 in this embodiment is mainly composed of an outer mast 1-1 and an inner mast 1-2. The outer mast 1-1 is used to be installed on the forklift frame, and the inner mast 1-2 is used to be installed inside the outer mast 1-1 and connected to the fork carriage 3. The lifting mechanism 2 is used to drive the inner mast 2 and the fork carriage 3 to move up and down in the height direction of the outer mast 1, that is, the lifting height of the fork 6 is slightly less than the sum of the heights of the outer mast 1-1 and the inner mast 1-2.

[0037] To achieve efficient, stable, and reliable lifting functions, the lifting mechanism 2 in this embodiment mainly consists of a lifting drive component 2-1 and a lifting transmission component 2-2. The lifting transmission component 2-2 is connected to the output end of the lifting drive component 2-1 and is used to drive the fork carriage 3, the loading attachment 4, and the forks 6 to move vertically. The lifting drive component 2-1 is a drive cylinder, and the lifting transmission component 2-2 is a chain or steel belt. The drive cylinder provides stable power output, driving the piston to extend and retract via hydraulic or pneumatic pressure, generating a strong thrust or pull force to drive the inner mast 1-2 to lift the fork carriage 3. The chain or steel belt, as a transmission element, can efficiently transmit the power of the cylinder to the fork carriage 3. Because chain or steel belt transmission has high efficiency, high load-bearing capacity, and good flexibility, it is suitable for use in forklifts and other equipment that require frequent lifting. In this embodiment, the combination of the chain and sprockets allows for a lifting distance greater than the stroke of the cylinder itself. For example, the cylinder stroke may only be a few tens of centimeters, but through chain drive, the lifting stroke of the fork carriage 3 can reach several meters, thus meeting the needs of forklifts in high-rack warehouses. This design can achieve a large lifting stroke without increasing the cylinder size, making the overall structure of the forklift more compact and saving space.

[0038] This embodiment presents a novel forklift working device with damping adjustment. This ingenious device incorporates a damping mechanism 5, which connects the fork carriage 3 to the loading attachment 4 and adjusts the angle of the loading attachment 4 to ensure the loading surface 6-1 of the forks 6 remains horizontal. This guarantees the balance of the goods under specific working conditions, exhibiting extremely high sensitivity. Furthermore, during forklift tilting and forklift jolting, the effective operation of the damping mechanism 5 ensures the loading surface 6-1 of the forks 6 remains horizontal, effectively preventing goods from slipping. This enhances the safety of the forklift during operation, improves the user experience, and facilitates the promotion and application of this forklift working device in the field of forklift technology.
