Description

Technical Field

[0001] The utility model relates to the technical field of handling equipment, in particular to a forklift with a foldable fork plate. Background Art

[0002] AGV forklift, or automatic navigation forklift, uses unmanned driving technology to achieve efficient and accurate material handling and storage tasks through autonomous navigation and perception systems. It is an indispensable tool for modern logistics and warehousing.

[0003] A Chinese patent discloses a narrow-aisle laser forklift AGV (authorization announcement number CN220664794U). The narrow-aisle laser forklift AGV provided by the utility model can adjust the distance between the two columns and reduce the width of the entire AGV by setting a laser forklift AGV body, a column, a plug plate, an adjustment mechanism and a lifting mechanism, so that the AGV can pass through the narrow alley smoothly without taking a detour, thereby improving transportation efficiency. The narrow-aisle laser forklift AGV with variable width has better passability and higher transportation efficiency.

[0004] Since the horizontal plate used to limit the columns in the above device is a fixed structure, when the adjustment mechanism adjusts the distance between the two columns, the size of the horizontal plate remains fixed. When the height of the narrow alley is higher than the horizontal plate, the horizontal plate will hinder the forklift from passing through the narrow alley, which will still slow down the transportation efficiency. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model aims to provide a forklift with a foldable fork plate to solve the problem that the existing forklift with the function of adjusting the width has a poor adjustment effect.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An embodiment of the present application provides a forklift with a foldable fork plate, comprising: a body, an operating handle and a main control box are installed on the top of the body, and two foldable fork plates are installed on one side of the body; a width adjustment mechanism, the width adjustment mechanism is installed on the surface of the body, and the two foldable fork plates are fixedly connected to the width adjustment mechanism.

[0008] Preferably, the width adjustment mechanism includes a mounting frame fixedly connected to the surface of the vehicle body, one end of the mounting frame is rotatably connected to a bidirectional lead screw, two oppositely threaded surfaces of the bidirectional lead screw are threadedly connected to threaded sleeves, both ends of the threaded sleeves are hinged with connecting rods, and a connecting block fixedly connected to a foldable fork plate is hinged between two adjacent connecting rods; the angle between two adjacent connecting rods is always less than one hundred and fifty degrees, and the angle between two adjacent connecting rods is toward the bidirectional lead screw.

[0009] In some embodiments, the width adjustment mechanism can not only center and simultaneously adjust the distance between the two folding fork plates to quickly adjust the overall width of the forklift, but also, since the two folding fork plates are respectively arranged on both sides of the forklift, when the user adjusts the distance between the two folding fork plates, the overall width of the forklift has been changed, and there will be no problem that some local structures cannot be adjusted, so as to ensure that the forklift after width adjustment can smoothly pass through a narrow lane with a corresponding width.

[0010] Preferably, the other end of the mounting frame is fixedly connected with a servo motor, and the output shaft of the servo motor is fixedly connected with the bidirectional lead screw.

[0011] In some embodiments, this can drive the bidirectional lead screw by means of electricity to reduce the adjustment burden on the staff.

[0012] Preferably, two guide rods are slidably connected inside the mounting frame, and one end of each guide rod penetrates out of the mounting frame and is fixedly connected with the folding fork plate; the horizontal cross-sectional shapes of the guide rods and the inner side of the mounting frame are both rectangular shapes that match each other.

[0013] In some embodiments, this can limit the running track of the folding fork plate to avoid the probability of the folding fork plate rotating or shifting.

[0014] Preferably, one end of the mounting frame is fixedly connected with a protective frame, the vertical cross-sectional shape of the protective frame is U-shaped, and the bidirectional lead screw and the threaded sleeve are both arranged inside the protective frame.

[0015] In some embodiments, this can block impurities such as dust and debris falling from top to bottom or from bottom to top onto the surface of the bidirectional lead screw to ensure that the threaded sleeve can slide smoothly on the surface of the bidirectional lead screw.

[0016] Preferably, a bearing is embedded and installed inside the protective frame, and the inner edge of the bearing is fixedly connected with the bidirectional lead screw.

[0017] In some embodiments, this can firmly limit the bidirectional lead screw in place to improve the running stability of the bidirectional lead screw.

[0018] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0019] The forklift with a folding fork plate provided by the embodiment of the present application. The width adjustment mechanism can not only adjust the distance between the two folding fork plates in the center at the same time to achieve the purpose of quickly adjusting the overall width of the forklift, but also because the two folding fork plates are respectively arranged on both sides of the forklift. When the user adjusts the distance between the two folding fork plates, the overall width of the forklift has been changed, and there will be no problem that the local structure cannot be adjusted, so as to ensure that the forklift after adjusting the width can smoothly pass through the narrow lane with the corresponding width.

When it is described that a specific device is connected to other devices, the specific device may be directly connected to the other devices without an intermediate device, or may not be directly connected to the other devices but have an intermediate device.

[0030] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the said technologies, methods, and devices should be regarded as part of the specification.

[0031] Referring to Figures 1 to 4 , this embodiment provides a forklift with a folding fork plate, including: a vehicle body 1, an operation handle 2 and a main control box 3 are installed on the top of the vehicle body 1, and two folding fork plates 5 are installed on one side of the vehicle body 1; a width adjustment mechanism 6, the width adjustment mechanism 6 is installed on the surface of the vehicle body 1, and both of the two folding fork plates 5 are fixedly connected to the width adjustment mechanism 6;

[0032] As Figures 2 to 4, the width adjustment mechanism 6 includes a mounting frame 61 fixedly connected to the surface of the vehicle body 1. One end of the mounting frame 61 is rotatably connected to a bidirectional lead screw 62. Threaded sleeves 63 are threadedly connected to the surfaces of the two opposite threads of the bidirectional lead screw 62. Connecting rods 64 are hinged to both ends of the threaded sleeve 63. A connecting block 65 fixedly connected to the folding fork plate 5 is hinged between two adjacent connecting rods 64; the included angle between two adjacent connecting rods 64 is always less than one hundred and fifty degrees, and the included angle between two adjacent connecting rods 64 faces the bidirectional lead screw 62; the other end of the mounting frame 61 is fixedly connected to a servo motor 66, and the output shaft of the servo motor 66 is fixedly connected to the bidirectional lead screw 62; two guide rods 67 are slidably connected inside the mounting frame 61. One end of the guide rod 67 penetrates out of the mounting frame 61 and is fixedly connected to the folding fork plate 5; the horizontal cross-sectional shapes of the guide rod 67 and the inner side of the mounting frame 61 are both rectangular shapes that match each other; one end of the mounting frame 61 is fixedly connected to a protective frame 68. The vertical cross-sectional shape of the protective frame 68 is U-shaped, and the bidirectional lead screw 62 and the threaded sleeve 63 are both arranged inside the protective frame 68; a bearing 69 is embedded inside the protective frame 68, and the inner edge of the bearing 69 is fixedly connected to the bidirectional lead screw 62.

[0033] Compared with the prior art, the above embodiment provides a forklift with a folding fork plate. When the user needs to adjust the overall width of the forklift, the user only needs to manually control the servo motor 66 to rotate in the corresponding direction. The servo motor 66 drives the bidirectional lead screw 62 to rotate. The bidirectional lead screw 62 drives the two threaded sleeves 63 to move towards or away from each other through two opposite threads at the same time. The two threaded sleeves 63 drive the two connecting rods 64 connected to them to move respectively. At this time, the included angle between two adjacent connecting rods 64 decreases or increases accordingly. The two adjacent connecting rods 64 drive the folding fork plate 5 to move away from or close to the bidirectional lead screw 62 through the connecting block 65. At this time, the distance between the two folding fork plates 5 increases or decreases accordingly, so as to achieve the purpose of centrally adjusting the overall width of the forklift. And because the two folding fork plates 5 are respectively arranged on both sides of the forklift, when the user adjusts the distance between the two folding fork plates 5, the overall width of the forklift has been changed, and there will be no problem that the local structure cannot be adjusted, so as to ensure that the forklift after adjusting the width can smoothly pass through a narrow lane with a corresponding width.

[0034] It should be noted that in the above description, the operating handle 2, the main control box 3, the folding fork plate 5, the bidirectional lead screw 62, and the servo motor 66 are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the operating handle 2, the main control box 3, and the servo motor 66 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0035] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0036] The above embodiments only express several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
