[0049] The present utility model provides a forklift, especially a miniaturized forklift, which can be used for cargo handling.

[0050] Refer to Figures 1 to 3 .

[0051] The bottom of the forklift main body 1 is provided with traveling wheels 2. The forklift main body 1 is made of a strengthened steel structure and can provide stable support. In this embodiment, in the direction from front to back, the cross-section of the forklift main body is approximately trapezoidal.

[0052] The first mounting plate 3 is a square plate and is mounted at the front end of the forklift main body 1. A plane perpendicular to the ground direction is formed at the front end of the forklift main body 1, and the first mounting plate 3 is mounted on this plane.

[0053] The fork arms include a pair of first fork arms 4 and second fork arms 5 used in pairs. The structures of the two fork arms are the same; taking the structure of the first fork arm 4 as an example, the structures of the two fork arms will be described. The first fork arm 4 includes a vertical fork arm section 401 and a first horizontal fork arm section 402; the first horizontal fork arm section 402 is located on the side close to the ground relative to the vertical fork arm section 401; the first horizontal fork arm section 402 is used as the working section and supports the product to be carried during the forklift loading process. Tooth-like structures 4021 are provided on both sides of the first horizontal fork arm section 402, which can play an auxiliary supporting role during the handling process and increase the supporting stability effect.

[0054] On the surface of the first mounting plate 3 facing the front side of the forklift body 1, there is a fork arm movement rail 301. The fork arm movement rail 301 is arranged along the direction parallel to the ground. The vertical fork arm segments 401 of the first fork arm and the second fork arm are movably installed on the fork arm movement rail 301 and can move along the fork arm movement rail 301.

[0055] In order to achieve automatic adjustment, in some embodiments of the present utility model, it further includes a first lead screw 6 and a first lead screw motor 7. The first lead screw 6 is connected to the first fork arm 4 and the second fork arm 5, and the first lead screw motor 7 is connected to the first lead screw 6.

[0056] When it is necessary to adjust the distance between the first fork arm 4 and the second fork arm 5 according to the size of the goods, start the first lead screw motor 7. The first lead screw motor 7 rotates, and then drives the first lead screw 6 to rotate. The first fork arm 4 and the second fork arm 5 can move along the fork arm movement rail 301. After adjustment in place, turn off the first lead screw motor 7.

[0057] In order to improve the stability of the cooperation structure between the two fork arms and the first mounting plate 3, in some embodiments of the present utility model, at least two fork arm movement rails 301 (including two) are provided on the surface of the first mounting plate 3 perpendicular to the ground. Each fork arm movement rail 301 is arranged at intervals along the direction perpendicular to the ground. The two fork arms are respectively slidably installed on the two fork arm movement rails 301 and move synchronously along the two fork arm movement rails 301 when adjusting the position.

[0058] In order to solve the installation problem between the two fork arms and the fork arm movement rail 301, in some embodiments of the present utility model, fork arm sliders 404 are provided on the installation sides of the first fork arm 4 and the second fork arm 5 and the fork arm movement rail 301. The fork arm sliders 404 are clamped on the fork arm movement rail so that the first fork arm 4 and the second fork arm 5 can move along the fork arm movement rail 301.

[0059] In some embodiments of the present utility model, the first mounting plate 3 further includes a plate surface 303 on the side parallel to the ground. The plate surface 303 on the side parallel to the ground is located on the side away from the ground relative to the vertical plate surface 304, and a fork arm movement rail 301 is also provided thereon. Both the first fork arm 4 and the second fork arm 5 include second horizontal fork arm segments 403, and the second horizontal fork arm segments 403 of both are movably connected to the fork arm movement rail 301 on the plate surface of the first mounting plate 3 parallel to the ground.

[0060] Through the above structure, the number of fork arm movement rails 301 is increased, and the stability of the cooperation movement structure between the mounting plate 3 and the fork arms can be improved.

[0061] Since the goods to be carried are generally heavy, in order to avoid deviation in the movement direction during the movement of the two fork arms, in some embodiments of the present utility model, a limiting rod 8 is further included, and the limiting rod 8 penetrates through the first fork arm 4 and the second fork arm 5. The limiting rod 8 is a straight rod and is installed along the horizontal direction. It can enable the two fork arms to move along the horizontal direction.

[0062] In order to fix the structure of the limiting rod 8, in some embodiments of the present utility model, a first limiting mounting block 901 and a second limiting mounting block 902 are horizontally and spacedly arranged on the first mounting plate 3, and the two limiting mounting blocks are at the same horizontal height. The passing-out end of the limiting rod 8 through the first fork arm 4 is connected to the first limiting mounting block 901, and the passing-out end of the limiting rod through the second fork arm 5 is connected to the second limiting mounting block 902.

[0063] In some embodiments of the present utility model, a second mounting plate 10 is further included, and the second mounting plate 10 is installed at the front end of the forklift body 1. The front end of the forklift body 1 has a plane perpendicular to the ground, and the second mounting plate 10 is installed on this plane. An installation plate movement rail 1001 is provided on the second mounting plate 10, and the first mounting plate 10 is movably installed on the installation plate movement rail 1001 and can move along the installation plate movement rail 1001.

[0064] In order to ensure the stability of the movement of the first mounting plate 3, there are also multiple installation plate movement rails 1001, and each installation plate movement rail 1001 is arranged parallel to the ground. A clamping block 302 is provided at the rear side of the plate surface of the first mounting plate 3, and it is installed on the installation plate movement rail 1001 through the clamping block 302.

[0065] The movement cooperation structure between the first mounting plate 3 and the second mounting plate 10 enables the position of the first mounting plate 3 to be adjusted, and can adapt to more application scenarios. In order to facilitate the adjustment of the position between the two mounting plates, a second lead screw 13 and a second lead screw motor 14 can be designed. Among them, the second lead screw 13 is installed with the first mounting plate 3, and the second lead screw motor 14 drives the second lead screw 13 to move.

[0066] In some embodiments of the present utility model, the forklift further includes a controller, and the controller is connected to the first lead screw motor and the second lead screw motor to control the operation of the first lead screw motor 7 and the second lead screw motor; a touch screen 12 is provided on the forklift body, and the touch screen 12 communicates with the controller.

[0067] This forklift can be designed in a miniaturized manner. In order to facilitate the pushing of the forklift, in some embodiments of the present utility model, a pushing handle 11 is installed on the forklift body 1.

[0068] A forklift for installing a cabinet transformer is particularly necessary. This forklift can adapt to transformers of different sizes and weights, provide precise control, and at the same time ensure the efficiency and safety of the handling process.

[0069] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
