Abstract
Description
Technical Field
[0001] The invention relates to the field of automated mechanical equipment, in particular to a universal frame with wide and narrow forks suitable for industrial vehicles. Background Art
[0002] Industrial vehicles refer to power-driven motor vehicles used to transport, push, pull, lift, stack or stack various goods. Common industrial vehicles include forklifts, side forklifts, tractors, transporters, stackers and so on.
[0003] For example, a forklift includes a main frame, a handle, a driving wheel, a lifting structure, a fork, etc. Among them, the fork is movably connected to the main frame. When the vehicle is working, driven by the lifting device, the fork extends horizontally and / or rises vertically relative to the main frame.
[0004] In the prior art, due to the difference in goods, especially the different widths of goods, different types of forklifts need to be used, i.e. wide forks and narrow forks of different widths. Due to the structural limitations of the vehicle body frame, when using different types of wide forks and narrow forks, the entire frame needs different molds and production to meet the needs of size changes, which reduces the efficiency of production, installation and transportation, and different molds also increase the cost of production and maintenance. Summary of the invention
[0005] The invention aims to provide a universal frame for wide and narrow forks suitable for industrial vehicles, which has good versatility and can adapt to the width requirements of different types of forks.
[0006] The above technical purpose of the present invention is achieved through the following technical solutions: a universal frame for wide and narrow forks suitable for industrial vehicles, comprising a main frame and a drive wheel assembly, and also comprising a rotating shaft and a separation connecting arm, wherein the separation connecting arm comprises a separation arm 1 and a separation arm 2 which are independent of each other, and the drive wheel assembly comprises a wheel frame, and the two ends of the separation arm 1 are respectively connected to the rotating shaft and the wheel frame, and the two ends of the separation arm 2 are respectively connected to the rotating shaft and the fork assembly.
[0007] As a preferred embodiment of the present invention, the fork assembly includes a push rod, and the second separation arm connects the rotating shaft and the push rod.
[0008] As a preferred embodiment of the present invention, the main frame includes side panels, the side panels are connected to connecting plates, and the rotating shaft is connected to the connecting plates.
[0009] As a preferred embodiment of the present invention, in the horizontal direction, the side plate is located between the separation arm 1 and the separation arm 2.
[0010] As a preferred embodiment of the present invention, the lower end of the side plate is provided with a passage for the rotation shaft to pass through.
[0011] As a preferred embodiment of the present invention, the position where the second separation arm is connected to the rotating shaft is farther away from the center axis of the vehicle in the horizontal direction than the position where the first separation arm is connected to the rotating shaft.
[0012] As a preferred embodiment of the present invention, the position where the connecting piece is connected to the rotating shaft is, in the horizontal direction, farther away from the center axis of the vehicle than the position where the second separation arm is connected to the rotating shaft.
[0013] As a preferred embodiment of the present invention, the separation arm 1 and the separation arm 2 are both in two sets and are located on both sides of the driving wheel assembly.
[0014] As a preferred embodiment of the present invention, a handle is connected to the driving wheel assembly, and a lifting device is connected to the main frame.
[0015] In summary, the present invention has the following beneficial effects:
[0016] 1. Driven by the lifting device and the rotating shaft, the separation arm 1 and the separation arm 2 match the forward movement and elevation of the fork assembly.
[0017] 2. Separation arm 1 and separation arm 2 are separated from each other, so that the entire vehicle middle part is a modular component. No matter how the width of the fork is set, this modular component does not need to be changed, has good stability, and avoids the cost of additional mold opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings.
[0023] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
[0024] Embodiment 1, as Figure 1 and Figure 2As shown, the universal frame for wide and narrow forks suitable for industrial vehicles can be different types of vehicles such as forklifts, stackers, sorting trucks, etc. This technical solution takes a forklift as an example. It includes a main frame 2, and the main frame 2 is connected to a driving wheel assembly 13 (the wheel body is not drawn in the figure), and the driving wheel assembly 13 includes a wheel frame 131 of the driving wheel. The driving wheel assembly 13 is directly connected to the handle 11, and the user directly controls the steering of the driving wheel by operating the handle 11.
[0025] The main frame 2 includes side panels 21 . The side panels 21 are composed of two pieces and extend in the vertical direction.
[0026] The rotating shaft 41 extends in the horizontal direction and is cylindrical, on which the separation arms are hinged. The separation arms are two sets, connected to the positions near the two ends of the rotating shaft 41, one on the left and one on the right. The separation arms are independent split designs, including a separation arm 1 42 and a separation arm 2 43. Figure 2 As shown, Figure 2 yes Figure 1 The enlarged detail view of point A is the specific structural view of the set of separation arms on the right side. On the far left is separation arm 1 42, with its two ends hinged to the rotating shaft 41 and the wheel frame 131 respectively. On the right is the side plate 21, and the lower part of the side plate 21 is a notch-shaped design for the rotating shaft 41 to pass through. On the right is separation arm 2 43, one end of which is hinged to the rotating shaft 41, and the other end is hinged to the push rod 31. On the right is the connecting piece 44, which is L-shaped, with one side connected to the side plate 21 and the other side connected to the rotating shaft 41. There are three important connection points in the figure, namely the connection point between separation arm 1 42 and the rotating shaft 41, namely point A in the figure; the connection point between separation arm 2 43 and the push rod 31, namely point C in the figure, and the connection point between connecting piece 44 and the rotating shaft 41, namely point B in the figure. Through the ABC three-point connection, the push rod 31 can achieve stable forward pushing and rising action.
[0027] Due to the separate design of the separation arm, when it is necessary to produce industrial vehicles with different fork widths such as wide forks and narrow forks, it is only necessary to adjust the installation position of the separation arm 2 43 and the components outside the separation arm 2 43, while all the mechanical components and electronic components in the central part of the entire vehicle body, that is, between the two side panels 21, do not need to be adjusted, thereby improving production and installation efficiency and reducing mold opening costs.
