Description

Technical Field

[0001] This utility model relates to the field of forklift technology, and in particular to a lightweight aluminum alloy frame for a truck-mounted forklift. Background Technology

[0002] Forklifts are industrial material handling vehicles, referring to various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transportation of palletized goods. They are commonly used for transporting large items in warehouses and are typically powered by fuel-powered engines or batteries. The technical parameters of a forklift indicate its structural characteristics and working performance. Key technical parameters include: rated lifting capacity, load center distance, maximum lifting height, mast tilt angle, maximum travel speed, minimum turning radius, minimum ground clearance, wheelbase, and track width.

[0003] Patent document CN106696666A discloses a single-drive electric forklift frame, including a frame body with a cavity for housing a battery and an opening on one side. The cavity's bottom plate has a notch communicating with the cavity, and symmetrical shelves for supporting the battery are pre-installed on both the front and rear sides of the bottom plate. The notch and the cavity opening are on the same side. A battery stop is axled on at least one side of the frame body near the cavity opening. A load-bearing plate is provided on the frame body to support the battery's weight, with an opening for the battery to enter and exit. Channel steel is welded to the inner side of the load-bearing top plate. The advantages are: the battery is positioned low, improving forklift stability; the cavity is open to the ground, allowing for side removal using a manual hydraulic trolley without the need for large tools, facilitating battery replacement; and the selection of the load-bearing plate and channel steel allows for the achievement of different tonnage frame bending strength requirements, demonstrating strong versatility.

[0004] While the aforementioned application can meet the bending strength requirements of different tonnage frames and has strong versatility, its large size makes it inconvenient to carry with the vehicle and takes up a lot of space during transport, thus affecting the forklift's ease of storage. Utility Model Content

[0005] This utility model discloses a lightweight aluminum alloy frame for truck-mounted forklifts, aiming to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lightweight aluminum alloy frame for a truck-mounted forklift includes a base, a battery inserted into one side of the base, a frame storage assembly on the upper surface of the base, a transmission assembly inside the frame storage assembly, and a rolling limit assembly at the bottom of the base.

A sliding plate 301 is threadedly connected to the lead screw 302. When the lead screw 302 rotates, it can drive the sliding plate 301 to move, thereby facilitating the adjustment of the position of the sliding rod 304 on the sliding plate 301. A sleeve is fitted on the top of the lead screw 302, and the top of the sleeve is fixedly connected to the inner top wall of the housing 300. The sleeve is rotatably connected to the lead screw 302. The sleeve is provided during use. The screw 302 can be limited, which facilitates the bottom limit of the screw 302 and prevents the screw 302 from shaking during rotation. The vertical rod 201 and the housing 300 are both provided with rod grooves for the slide rod 304 to pass through, and the inner wall of the rod groove is slidably connected to the surface of the slide rod 304. The rod grooves can be used to limit the slide rod 304 during use, thereby maintaining the stability of the slide rod 304's movement. A support plate 307 is fixedly installed on one side of the mounting base 308, and the top of the support plate 307 is in contact with the bottom of the horizontal rod 202.

[0036] The transmission component 3 can lift the goods during use, which facilitates the transfer of goods and saves manpower. The support plate 307 can support the crossbar 202 on the mounting base 308 during use, thereby preventing the crossbar 202 from being overloaded.

[0037] Reference Figure 4In a preferred embodiment, the rolling limiting component 4 includes a universal wheel 400 fixedly installed on one side of the bottom of the base 1 and a directional wheel 401 fixedly installed on the other side of the bottom of the base 1.

A threaded rod 406 is inserted into the elongated plate 405. One end of the threaded rod 406 is rotatably connected to a positioning plate 407 through a bearing. The top of the positioning plate 407 is fixedly connected to the bottom of the base 1. An arc-shaped clamping plate 408 is fixedly installed on one end of the connecting rod 403. One side of the arc-shaped clamping plate 408 is in contact with the surface of the directional wheel 401. The rolling limiting component 4 can limit the overall movement during use, preventing the frame from rolling during the lifting of objects under force, maintaining the overall placement stability of the frame, and reducing frame sway.

[0038] Working principle: When the frame needs to be folded and stored, the control motor 305 is activated. The motor 305 drives the slide plate 301 on the lead screw 302 to move downwards, which in turn causes the limit block 303 on the slide rod 304 and the mounting base 308 to move downwards to their lowest point. Then, the electric push rod 200 is retracted. The retraction of the electric push rod 200 causes the vertical rod 201 to rotate in the direction of the electric push rod 200. The electric push rod 201 enters the groove on the base 1, and then the vertical rod 201 becomes parallel to the base 1. Simultaneously, under the action of gravity, the crossbar 202 will also rotate to the left, making the crossbar 202 parallel to the vertical bar 201, thereby realizing the overall folding of the frame and the storage of the frame. The frame can be moved as a whole by the casters 400 and the fixed wheels 401. When the frame needs to be positioned, tighten the threaded rod 406, so that the threaded rod 406 drives the plug rod 403 and the arc-shaped clamping plate 408 on the connecting plate 404 to fit against the surface of the fixed wheel 401, thus limiting the fixed wheel 401.

[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
