Description

Technical Field

[0001] This application relates to the field of AGV technology, and in particular to an AGV forklift. Background Technology

[0002] With the widespread use of AGV (Automated Guided Vehicle) forklifts in warehousing and logistics, more and more industries (such as food, pharmaceuticals, and biotechnology) have oil-proof or cleanliness requirements for forklifts to prevent contamination of goods. Currently, common AGV forklifts typically have lubricating oil applied to their surfaces to reduce frictional resistance during fork spacing adjustments.

[0003] However, in actual operation, the lubricating oil coated on the surface of the AGV forklift will drip off the surface of the AGV forklift, causing the oil from the AGV forklift itself to contaminate the goods being transported, failing to meet the oil-proof and cleanliness requirements of the goods for the AGV forklift and the usage scenario. Utility Model Content

[0004] The purpose of this application is to provide an AGV forklift that reduces the contamination of goods by the oil from the AGV forklift itself, thereby improving the oil resistance and cleanliness of the AGV forklift. The specific technical solution is as follows:

[0014] The forks are equipped with anti-wear components; the anti-wear components slide against the slide rail.

[0015] The AGV forklift also includes a second oil tank, which has an upward opening and is fixed below the slide rail.

[0016] In some embodiments of this application, the forks include a fork body and a guide shaft connecting block;

[0017] The fork body includes a connecting portion extending in a vertical direction and a cargo-carrying portion extending in a direction away from the vehicle body; the anti-wear component is disposed on the side of the connecting portion facing the fork carriage;

[0018] The guide shaft connecting block is fixed to the end of the connecting part away from the cargo part, and a bushing is provided on the guide shaft connecting block; the guide shaft passes through the bushing.

[0019] In some embodiments of this application, the anti-wear component includes a connected anti-wear slider and a slider fixing seat; the slider fixing seat is fixed to the connecting part of the fork body facing the slide rail, and the anti-wear slider slides against the slide rail;

[0020] The slider mounting base is provided with an oil guide plate that extends obliquely toward the second oil groove on the side away from the fork body.

[0021] In some embodiments of this application, the AGV forklift further includes:

[0022] An adjustable pitch accordion cover is located between the two forks, and its two ends are fixedly connected to the opposite sides of the two forks, respectively.

[0023] In some embodiments of this application, the AGV forklift further includes:

[0024] Multiple guide shaft bellows covers, wherein the guide shaft bellows covers are fitted onto the guide shaft and have an opening at the bottom;

[0025] In the presence of one guide shaft, the guide shaft bellows cover is disposed between the fork and the fork carriage, and between the two forks;

[0033] Beneficial effects:

[0034] This application provides an AGV forklift. When the AGV forklift is working, grease and lubricating oil are typically applied to the guide shaft to reduce friction between the forks and the guide shaft. The forks can slide along the extension direction of the guide shaft under the drive of the fork drive assembly. During the sliding process, the contact surface between the forks and the guide shaft scrapes the oil applied to the guide shaft, causing the oil to drip downwards from the guide shaft. Since each guide shaft has a first oil groove at its bottom, the dripping oil can flow into the first oil groove, reducing the contamination of goods by the AGV forklift's own oil, thereby improving the AGV forklift's oil resistance and cleanliness. Furthermore, the two forks have a symmetrical structure, and the two forks are independently controlled by two fork drive assemblies. This not only enables the overall left and right movement of the forks but also allows for the expansion and contraction of the fork distance, facilitating the adjustment of the goods placement position.

[0035] Of course, any product implementing this application does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0058] This application provides an AGV forklift, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the AGV forklift provided in this application. The AGV forklift includes: a vehicle body 1; a fork spacing adjustment mechanism 2, including a fork carriage 21, at least one guide shaft 22, two forks 23, and two fork drive assemblies 24; the guide shaft 22 is horizontally mounted on the fork carriage 21; each guide shaft 22 is slidably connected to at least one fork 23; the fixed end of each fork drive assembly 24 is fixed to the fork carriage 21, and the drive end is connected to one fork 23; at least one first oil groove 3 with an upward opening, and a first oil groove 3 is provided below each guide shaft 22.

[0059] In this embodiment, when the AGV forklift is working, grease and lubricating oil are typically applied to the guide shaft 22 to reduce friction between the forks 23 and the guide shaft 22. The forks 23 can slide along the extension direction of the guide shaft 22 under the drive of the fork drive assembly 24. During sliding, the contact surfaces of the forks 23 and the guide shaft 22 scrape against the oil applied to the guide shaft 22, causing the oil to drip downwards from the guide shaft 22. Since each guide shaft 22 has a first oil groove 3 at its bottom, the dripping oil can flow into the first oil groove 3, reducing the contamination of goods by the AGV forklift's own oil, thereby improving the AGV forklift's oil resistance and cleanliness. Furthermore, the two forks 23 have a symmetrical structure, and the two forks 23 are independently controlled by the two fork drive assemblies 24. This not only enables the overall left and right movement of the forks 23, but also allows for the expansion and contraction of the forks 23, facilitating the adjustment of the goods placement position.

[0060] like Figure 2 and Figure 3 As shown, Figure 2 This is a structural schematic diagram of the fork spacing adjustment mechanism of the AGV forklift provided in this application; Figure 3 for Figure 2The diagram shows a front view of the fork adjustment mechanism. The fork carriage 21 may include a crossbeam 212 and two side plates 213 respectively fixed to both ends of the crossbeam 212. At least one end of the guide shaft 22 is fixed to the side plate 213. The guide shaft 22 is located on the side of the crossbeam 212 away from the vehicle body 1 and is installed between the two side plates 213.

[0061] In addition, such as Figure 4 As shown, Figure 4 This is a schematic diagram of the fork carriage of the AGV forklift provided in this application. At least one guide shaft seat 2121 can also be provided on the side of the crossbeam 212 away from the vehicle body 1. The guide shaft seat 2121 is spaced apart from the two side plates 213. The guide shaft 22 passes through the guide shaft seat 2121 and is fixedly connected to the guide shaft seat 2121.

[0062] In one exemplary embodiment, taking one guide shaft 22 as an example, both ends of the guide shaft 22 are fixedly connected to the two side plates 213 of the fork carriage 21, and two forks 23 are connected to the guide shaft 22. In this case, a guide shaft seat 2121 can be provided at the middle position of the crossbeam 212 of the fork carriage 21, through which the guide shaft 22 passes, providing support for the middle part of the guide shaft 22. In this configuration, both ends of the first oil groove 3 can be fixed to the two side plates 213 respectively.

[0063] In one exemplary embodiment, taking two guide shafts 22 as an example, such as... Figure 2 and Figure 3 As shown, the crossbeam 212 of the fork carriage 21 has two spaced guide shaft seats 2121. Each guide shaft seat 2121 is connected to a nearby side plate 213 with a guide shaft 22, and each guide shaft 22 is equipped with a fork 23. One end of the guide shaft 22 is fixed to the side plate 213, and the other end is fixed to the guide shaft seat 2121. See [reference needed] in this case. Figures 2 to 4 , Figure 6 This is a structural schematic diagram of the fork carriage of the AGV forklift provided in this application. Oil groove fixing seats are provided on opposite sides of the two side plates 213. Each guide shaft seat 2121 also has an oil groove fixing seat on the side facing the side plate 213 closest to it. There are two first oil grooves 3. Each guide shaft seat 2121 has a first oil groove 3 between it and the side plate 213 closest to it. Both ends of each first oil groove 3 are fixedly connected to the oil groove fixing seats on the guide shaft seat 2121 and the side plate 213, respectively.

[0064] In some implementations of this application, such as Figures 2 to 4 As shown, the fork offset mechanism 2 also includes: a first oil guide ring 25; the first oil guide ring 25 is disposed on the fork 23, located at the connection between the fork 23 and the guide shaft 22, surrounds the guide shaft 22, and the bottom of the first oil guide ring 25 has an opening.

[0065] In this embodiment, first oil guide rings 25 are provided on both sides of the fork 23, and the first oil guide rings 25 protrude outward from both sides of the fork 23 along the extension direction of the guide shaft 22. That is, the end of the first oil guide ring 25 away from the side wall of the fork 23 has a certain distance from the side wall of the fork 23. This allows the first oil guide ring 25 surrounding the guide shaft 22 to block the oil splashed from the guide shaft 22 towards the inner side wall of the guide shaft 22, thereby reducing the probability of the AGV forklift's own oil splashing onto the goods and reducing the contamination of the goods. At the same time, the flowing oil, under the guidance of the first oil guide rings 25 on both sides of the fork 23, can flow from the opening at the bottom of the first oil guide ring 25 into the first oil groove 3 below the guide shaft 22, further reducing the contamination of the goods by the splashed oil.

[0066] In some implementations of this application, such as Figures 2 to 4 As shown, the fork offset mechanism 2 also includes a second oil guide ring 26; the second oil guide ring 26 is disposed on the fork carriage 21, located at the connection between the guide shaft 22 and the fork carriage 21, surrounds the guide shaft 22, and has an opening at the bottom.

[0067] In this embodiment, a second oil guide ring 26 is provided on the fork carriage 21. Similar to the aforementioned first oil guide ring 25, the second oil guide ring 26 protrudes outward from the fork carriage 21 along the extending direction of the guide shaft 22. This allows the second oil guide ring 26, surrounding the guide shaft 22, to block oil splashed from the guide shaft 22 from the inner wall of the guide shaft 22, thereby reducing the probability of oil from the AGV forklift splashing onto the goods and reducing contamination of the goods. At the same time, the flowing oil, guided by the second oil guide ring 26 on the fork carriage 21, can flow from the opening at the bottom of the second oil guide ring 26 into the first oil groove 3 below the guide shaft 22, further reducing the contamination of the goods by splashed oil. The first oil guide ring 25 and the second oil guide ring 26 can be connected to the fork 23 and the fork carriage 21 respectively by welding.

[0068] In the case where the fork carriage 21 has two side plates 213 and a guide shaft seat 2121, the second oil guide ring 26 can be disposed on one side opposite to the two side plates 213. The end of the second oil guide ring 26 on the side plate 213 away from the side plate 213 is at a certain distance from the side of the side plate 213 on which the second oil guide ring 26 is mounted. Alternatively, the second oil guide ring 26 can be disposed on the side wall of the guide shaft seat 2121 along the extending direction of the guide shaft 22, with the end of the second oil guide ring 26 on the guide shaft seat 2121 away from the side wall of the guide shaft seat 2121 at a certain distance from that side wall of the guide shaft seat 2121.

[0069] In one exemplary embodiment, taking one guide shaft 22 as an example, the guide shaft seat 2121 is provided with a second oil guide ring 26 on both sides facing the two side plates 213.

[0070] In one exemplary embodiment, taking two guide shafts 22 as an example, such as... Figure 2 As shown, each guide shaft seat 2121 is provided with a second oil guide ring 26 on the side facing the side plate 213 closest to it.

[0071] Of course, the specific structure of the fork offset mechanism 2 can also be adjusted according to actual needs, as long as the first oil tank 3 can receive the dripping oil.

[0072] In some implementations of this application, such as Figure 2 and Figure 3 As shown, the fork carriage 21 includes a slide rail 211 located below the first oil groove 3; the fork 23 is provided with an anti-wear component 231; the anti-wear component 231 slides against the slide rail 211; the AGV forklift also includes a second oil groove 4, the second oil groove 4 opening upward and fixed below the slide rail 211.

[0073] In this embodiment, the end of the fork 23 furthest from the guide shaft 22 can slide against the slide rail 211. This allows the slide rail 211 to provide support for the lower part of the fork 23. This prevents the fork 23 from rotating around the guide shaft 22 towards the fork carriage 21, thereby improving the stability of the fork 23 when handling goods. During sliding, the anti-wear component 231 on the fork 23 slides against the slide rail 211, reducing damage to the fork 23 during sliding. Simultaneously, to reduce friction between the anti-wear component 231 and the slide rail 211, oil is coated between them. Scratching of the contact surfaces causes the oil to drip downwards, and the second oil groove 4 located below the slide rail 211 can collect the dripping oil, reducing the contamination of goods by the AGV forklift's own oil, thereby improving the AGV forklift's oil resistance and cleanliness. Specifically, oil groove fixing seats can be set at both ends of the slide 211, and the two ends of the second oil groove 4 can be fixedly connected to the oil groove fixing seats of the slide 211 respectively.

[0074] In some implementations of this application, such as Figures 5 to 7 As shown, Figure 5 A schematic diagram of the forks of the AGV forklift provided in this application; Figure 6 for Figure 5 A magnified view of a section of M1; Figure 7 This is a structural schematic diagram of the fork of the AGV forklift provided in this application from another perspective. The fork 23 includes a fork body 232 and a guide shaft connecting block 233; the fork body 232 includes a connecting part extending in the vertical direction and a loading part extending in the direction away from the vehicle body 1; the anti-wear component 231 is disposed on the side of the connecting part facing the fork carriage 21; the guide shaft connecting block 233 is fixed to the end of the connecting part away from the loading part, and a bushing 2331 is disposed on the guide shaft connecting block 233; the guide shaft 22 passes through the bushing 2331.

[0075] In this embodiment, see Figure 2 The guide shaft connecting block 233 of the fork 23 is slidably connected to the guide shaft 22 at one end near the fork carriage 21 via a bushing 2331. The fork body 232 is located below the end of the guide shaft connecting block 233 away from the fork carriage 21. This allows the anti-wear component 231 on the connecting part of the fork body 232 to slide against the slide rail 211. The bushing 2331 can be made of brass.

[0076] In some embodiments, see Figure 6 A first grease nipple 2332 can be provided on the top of the guide shaft connecting block 233, penetrating the bushing 2331. When lubrication is required between the guide shaft 22 and the fork 23, grease or lubricating oil can be added directly between them through the first grease nipple 2332.

[0077] In some embodiments of this application, such as Figure 2 , Figure 5 and Figure 7 As shown, the anti-wear component 231 includes a connected anti-wear slider 2311 and a slider fixing seat 2312; the slider fixing seat 2312 is fixed to the side of the connecting part of the fork body 232 facing the slide rail 211, and the anti-wear slider 2311 slides against the slide rail 211; an oil guide plate 2313 extending obliquely toward the second oil groove 4 is provided on the side of the slider fixing seat 2312 away from the fork body 232.

[0078] In this embodiment, the anti-wear slider 2311 in the anti-wear component 231 is installed on the fork body 232 through the slider fixing seat 2312, and the oil guide plate 2313 on the slider fixing seat 2312 can block the oil splashed from the slide 211 and guide the oil into the second oil tank 4 through the inclined structure at the bottom.

[0079] Specifically, such as Figures 8 to 10 As shown, Figure 8 A schematic diagram of the anti-wear slider of the AGV forklift provided in this application; Figure 9 Another structural schematic diagram of the anti-wear slider of the AGV forklift provided in this application; Figure 10This is a structural schematic diagram of the anti-wear slider of the AGV forklift provided in this application from another perspective. The top of the anti-wear slider 2311 has a second grease nipple 23111, through which grease or lubricant can be directly added between the anti-wear slider 2311 and the slide rail 211. The grease or lubricant flows through the second grease nipple 23111 into the groove 23113 on the side of the anti-wear slider 2311 facing the slide rail 211, thereby creating lubrication between the anti-wear slider 2311 and the slide rail 211. In addition, a connecting protrusion 23112 can be provided on the side of the anti-wear slider 2311 facing the slider fixing seat 2312. The connecting protrusion 23112 can be inserted into the slider fixing seat 2312 to install the anti-wear slider 2311 onto the slider fixing seat 2312.

[0080] In some implementations of this application, such as Figure 10 As shown, Figure 10 This is a schematic diagram of the structure of the AGV forklift with a bellows cover provided in this application. The AGV forklift also includes: an adjustable bellows cover 5, which is located between the two forks 23, and the two ends of the adjustable bellows cover 5 are fixedly connected to the opposite side of the two forks 23 respectively.

[0081] In this embodiment, an adjustable accordion cover 5 is provided between the two forks 23, and the two ends of the adjustable accordion cover 5 are fixedly connected to the opposite sides of the two forks 23, respectively. In this way, when the distance between the two forks 23 is adjusted, the adjustable accordion cover 5 can extend and retract along the sliding direction of the forks 23 under the action of the forks 23, so as to cover the space between the two forks 23, thereby preventing dust from one side of the vehicle body 1 from entering the cargo area between the two forks 23, thereby reducing the pollution of the cargo by the surrounding dust during the distance adjustment.

[0082] In some embodiments of this application, such as Figure 10 and Figure 11 As shown, Figure 11 for Figure 10 The diagram shows the structural schematic of the guide shaft bellows cover. The AGV forklift also includes: multiple guide shaft bellows covers 6, which are fitted onto the guide shaft 22 and have an opening at the bottom; when there is one guide shaft 22, the guide shaft bellows cover 6 is located between the fork 23 and the fork carriage 21, and between two forks 23; when there are multiple guide shafts 22, the guide shaft bellows cover 6 is located between the fork 23 and the fork carriage 21.

[0083] In this embodiment, a guide shaft bellows cover 6 can be fitted onto the guide shaft 22. The guide shaft bellows cover 6 can extend and retract along the sliding direction of the fork 23. The guide shaft bellows cover 6 prevents dust from entering between the fork 23 and the guide shaft 22, thus avoiding the problem of dust mixing with lubricant affecting the pitch adjustment function. See also Figure 11The bottom of the guide shaft bellows cover 6 has an opening, through which the lubricant on the guide shaft 22 can drip into the first oil groove 3 below the guide shaft 22.

[0084] In one exemplary embodiment, when there is only one guide shaft 22, if a guide shaft seat 2121 is provided on the crossbeam 212 of the fork carriage 21, the two ends of the guide shaft bellows cover 6 located between the side plate 213 and the fork 23 of the fork carriage 21 can be fixedly connected to the side plate 213 and the fork 23 respectively, and the two ends of the guide shaft bellows cover 6 located between the fork 23 and the guide shaft seat 2121 can be fixedly connected to the fork 23 and the guide shaft seat 2121 respectively. If the crossbeam 212 of the fork carriage 21 does not have a guide shaft seat 2121, the two ends of the guide shaft bellows cover 6 located between the side plate 213 and the fork 23 of the fork carriage 21 can be fixedly connected to the side plate 213 and the fork 23 respectively, and the two ends of the guide shaft bellows cover 6 located between two forks 23 can be fixedly connected to two forks 23 respectively.

[0085] In one exemplary embodiment, when there are two guide shafts 22, two guide shaft seats 2121 are provided on the crossbeam 212. At this time, the two ends of the guide shaft bellows cover 6 located between the side plate 213 and the fork 23 of the fork carriage 21 are fixedly connected to the side plate 213 and the fork 23 respectively, and the two ends of the guide shaft bellows cover 6 located between the fork 23 and the guide shaft seat 2121 are fixedly connected to the fork 23 and the guide shaft seat 2121 respectively.

[0086] Of course, the installation position of the guide shaft bellows cover 6 can be changed according to actual needs, as long as the guide shaft bellows cover 6 can be placed on the guide shaft 22.

[0087] In some embodiments of this application, such as Figure 1 and Figure 10 As shown, the vehicle body 1 includes a lifting mast 11; the fork carriage 21 is connected to the lifting mast 11 in a height-adjustable manner via a lifting assembly on the side facing the vehicle body 1; the AGV forklift also includes a lifting bellows cover 7; the bottom of the lifting bellows cover 7 is fixedly connected to the top of the fork carriage 21, and the top is fixedly connected to the top of the lifting mast 11.

[0088] In this embodiment, as Figure 1 and Figure 4As shown, a connecting frame 214 is also provided on the side of the fork carriage 21 facing the vehicle body 1. The connecting frame 214 is connected to the lifting assembly on the vehicle body 1, enabling the fork spacing mechanism 2 to move up and down along the height direction of the lifting mast 11 under the drive of the lifting assembly. An upper mounting plate 2122 can be provided on the top of the crossbeam 212. The bottom of the lifting bellows cover 7 is fixedly connected to the upper mounting plate 2122, and the top is fixedly connected to the top of the lifting mast 11 of the vehicle body 1. In this way, when the fork spacing mechanism 2 is raised and lowered, the lifting bellows cover 7 can extend and retract along the height direction of the lifting mast 11 to reduce the amount of dust above and around the vehicle body 1 entering the cargo area, thereby reducing the contamination of the cargo by the surrounding dust during the lifting process.

[0089] This application addresses the issue of dust entering the cargo area by installing bellows covers on the AGV forklift, reducing the adverse effects of dust mixing with lubricant. Furthermore, each bellows cover not only blocks dust but also minimizes moisture entering the cargo area. In other words, this application achieves three-fold protection for the AGV forklift—oil, dust, and water—through the combined action of oil troughs, oil guide rings, oil guide plates, and bellows covers. Moreover, the first oil trough 3, the second oil trough 4, the adjustable bellows cover 5, the guide shaft bellows cover 6, and the lifting bellows cover 7 can all be detachably connected to the fork adjustment mechanism 2, facilitating inspection, maintenance, and replacement.

[0090] In some implementations of this application, such as Figure 2 and Figure 3 As shown, the fork drive assembly 24 includes an electric actuator 241 and an electric actuator mounting base 242; the electric actuator mounting base 242 is fixed to the fork carriage 21, one end of the electric actuator 241 is fixedly connected to the electric actuator mounting base 242, and the other end is fixedly connected to the fork 23.

[0091] In this embodiment, the fork drive assembly 24 is driven by a motor. The electric actuator mounting base 242 of the fork drive assembly 24 can be fixedly installed on the connecting frame 214. A push rod connecting block 2321 can be set on the side of the connecting part of the fork body 232 of the fork 23 facing the fork carriage 21. One end of the electric actuator 241 is connected to the electric actuator mounting base 242, and the other end is connected to the push rod connecting block 2321 on the fork 23. By using the electric actuator 241 to control the movement of the fork 23, compared with using a hydraulic cylinder to adjust the distance of the AGV forklift's forks 23, problems such as hydraulic oil leakage will not occur during actual use and maintenance, further reducing the contamination of goods by the AGV forklift's own oil, thereby improving the oil resistance and cleanliness of the AGV forklift.

[0092] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
