Description

Technical Field

[0001] This utility model relates to the field of forklift technology, and in particular to a forklift mast. Background Technology

[0002] In related technologies, forklift masts include forks and drive components that drive the forks to move vertically. Lifting goods using only a single fork is relatively inefficient.

[0003] A forklift mast with application number CN202322752373.1 is disclosed. This application includes an outer mast, an inner mast, a movable frame, and forks. The inner mast is slidably connected to the outer mast, the movable frame is connected to the inner mast, and the forks are rotatably connected to the movable frame. The forks have insert slots, and the forklift mast includes an embedded fork carriage, at least partially located within the insert slot. The embedded fork carriage is slidably connected to the forks, and the sliding direction of the embedded fork carriage is parallel to the sliding direction of the movable frame. The forklift mast includes a first hydraulic cylinder, a chain, and a sprocket. The sprocket is rotatably connected to the movable frame and located above the embedded fork carriage. One end of the chain is connected to the embedded fork carriage, and the other end of the chain passes around the sprocket and engages with the sprocket. The other end of the chain is connected to a sliding rod of the first hydraulic cylinder, and the cylinder body of the first hydraulic cylinder is connected to the forks. Although the device can pick up two items at a time, improving work efficiency, there is still room for improvement in this efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a forklift mast.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A forklift mast includes a connecting plate, a hydraulic cylinder, a first fork, and a second fork. The forklift is characterized by having a storage groove at the bottom of the first fork for storing a fork plate, a sliding plate connected to the fork plate, the sliding plate being slidably connected to the first fork, and a driving device connected to the connecting plate for driving the sliding plate to slide up and down.

[0007] Preferably, a sliding groove is provided on the back of the first fork, the bottom of the sliding groove is connected to the storage groove, and a sliding plate is slidably connected in the sliding groove.

[0008] Preferably, the driving device is a dual-axis motor, which is connected to the connecting plate, and gears are connected to both output shafts of the dual-axis motor.

[0009] Preferably, a rack is connected to one side of each of the sliding plates, and the rack meshes with a gear.

[0010] The advantages of this utility model are as follows: The forklift mast provided by this utility model drives the sliding plate to move up and down through the drive device, and the sliding plate drives the fork plate to move up and down, so that the first fork, the second fork and the fork plate in this mast can pick up goods respectively, thereby improving work efficiency.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0015] like Figure 1 As shown, the present invention provides a forklift mast, including a connecting plate 1, a hydraulic cylinder 2, a first fork 3, and a second fork 4.

[0016] like Figure 2 As shown, a storage groove 5 is provided at the bottom of the first fork 3, and the fork plate 8 is stored in the storage groove 5. A sliding plate 9 is connected to the fork plate 8 and is slidably connected to the first fork 3. That is, a sliding groove 7 is provided on the back of the first fork 3. The cross-section of the sliding groove 7 is convex. The bottom of the sliding groove 7 is connected to the storage groove 5. The sliding plate 9 is slidably connected in the sliding groove 7. The sliding of the sliding plate 9 in the sliding groove 7 drives the fork plate 8 to move up and down.

[0017] A drive device 6 is connected to the connecting plate 1. The drive device 6 is used to drive the sliding plate 9 to slide up and down. The drive device 6 is a dual-axis motor with a self-locking function. The dual-axis motor is connected to the bottom of the connecting plate 1. Gears 6.1 are connected to both output shafts of the dual-axis motor. A rack 9.1 is connected to one side of each sliding plate 9. The rack 9.1 is set in the sliding groove 7 to prevent the rack 9.1 from hitting the connecting plate 1 when moving up and down. The gear 6.1 meshes with the rack 9.1. The dual-axis motor drives the gear 6.1 to rotate. The gear 6.1 drives the rack 9.1, which in turn drives the sliding plate 9 to move. The sliding plate 9 drives the fork plate 8 to move.

[0018] When this gantry is in use, the first fork 3 picks up the first item, then the hydraulic cylinder 2 is activated to move the second fork 4 upward. Next, the first fork 3 picks up the second item. After picking up the item, the first fork 3 moves upward. At this time, the drive device 6 is activated to move the fork plate 8 downward, so that the fork plate 8 picks up the third item. Therefore, this gantry can pick up three items at a time, which significantly improves work efficiency.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
