Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical equipment technology, and more specifically, to a logistics forklift. Background Technology
[0002] Logistics forklifts are material handling equipment widely used in logistics, warehousing, and manufacturing industries. Their forklift arms typically only perform lifting and lowering movements and cannot turn horizontally. Although some electric forklifts can achieve steering with the base carrying the forklift body, the turning radius is large, and they are primarily used for steering purposes. Therefore, this utility model proposes a logistics forklift. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a logistics forklift.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The logistics forklift involved in this utility model includes a lifting fork arm assembly. The front end of the fork arm assembly is provided with a movable seat. The movable seat is provided with two fork arm arms that are symmetrically arranged from left to right and extend horizontally forward. A left guide sleeve and a right guide sleeve are fixedly connected to the fork arm assembly. The right guide sleeve and the left guide sleeve both extend circumferentially around the same structural circle. A matching left adjusting crank arm is slidably connected inside the left guide sleeve. A matching right adjusting crank arm is slidably connected inside the right guide sleeve. The front ends of the right adjusting crank arm and the left adjusting crank arm are both connected to the movable seat. A rack is arranged along its extension trajectory on the inner or outer side of the left or right adjusting crank arm. An adjusting gear is rotatably connected to the fork arm assembly on the rack. A power assembly for controlling rotation is transmitted to the adjusting gear.
[0005] The present invention is further configured such that the rack is located on the inner side of the left adjusting crank arm.
[0006] The present invention is further configured such that the powertrain includes a geared motor mounted on the fork arm assembly.
[0007] In summary, this utility model has the following beneficial effects:
[0008] 1. The fork arm can be turned slightly, making the material unloading position precise.
[0009] 2. Large-diameter curved guide sleeves and curved guide rods are used for adjustment to ensure smooth steering while maintaining high load-bearing capacity. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the overall structure of this utility model. Detailed Implementation
[0011] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0012] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0013] Example 1
[0014] See Figure 1 As shown, the logistics forklift involved in this embodiment includes a lifting fork arm assembly 1. The front end of the fork arm assembly 1 is provided with a movable seat 2. The movable seat 2 is provided with two fork arm arms 3 arranged symmetrically from left to right and extending horizontally forward. A left guide sleeve 4 and a right guide sleeve 5 are fixedly connected to the fork arm assembly 1. The right guide sleeve 5 and the left guide sleeve 4 both extend circumferentially around the same structural circle. A left adjusting crank arm 6 is slidably connected inside the left guide sleeve 4. A right adjusting crank arm 7 is slidably connected inside the right guide sleeve 5. The front ends of the right adjusting crank arm 7 and the left adjusting crank arm 6 are both connected to the movable seat 2. A rack 8 is arranged on the inner side of the left adjusting crank arm 6 along its extension trajectory. An adjusting gear 9 is meshed on the rack 8 and rotatably connected to the fork arm assembly. A power assembly (not shown) for controlling rotation is transmitted to the adjusting gear 9. The power assembly includes a reduction motor provided on the fork arm assembly.
[0015] In this implementation scheme, by operating the reduction motor, the adjusting gear 9 is driven to rotate clockwise or counterclockwise. Through the meshing rack 8, the left adjusting crank arm 6 carries the movable seat 2 to slide in a curve relative to the left guide sleeve 4. During this period, the right guide sleeve 5 and the right adjusting crank arm 7 provide guidance and auxiliary transmission, so that the fork arm 3 can be finely adjusted in orientation in the horizontal plane, making the unloading position adjustable and accurate.
[0016] The logistics forklift involved in this utility model has a fork arm that can achieve slight steering, making the unloading position precise; and it uses a large-diameter curved guide sleeve and curved guide rod for adjustment, which ensures smooth steering, high load-bearing capacity, complete overall function and strong practicality.
[0017] Unless otherwise specified, in this utility model, terms such as "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the actual orientation or positional relationship shown. They are used 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.
