[0002] Forklifts, as a common type of industrial handling vehicle, are widely used in ports, railway stations, airports, freight yards, factory workshops, warehouses, distribution centers, and other places. They are highly efficient vehicles for loading, unloading, stacking, and short-distance transportation of palletized goods. The forklift frame (also known as the fork carriage) is the core component of the forklift's working device.

[0003] For example, patent application CN202420488232.5 discloses an adjustable forklift frame. In this application, two forklift frames are provided at the front end of the forklift body. A slider three is fixedly connected to the back of the two forklift frames. A bidirectional lead screw is movably connected to the middle of the slider three. The slider three and the bidirectional lead screw are located inside a crossbar groove. A protective box is fixedly provided at one end of the crossbar groove. A stepper motor is installed inside the protective box, and the output end of the stepper motor is connected to the bidirectional lead screw. By setting up a component structure that allows for adjusting the distance between the forklift frames, the device can work efficiently according to actual conditions. Activating the stepper motor inside the protective box can drive the slider three on the surface of the bidirectional lead screw to adjust, thereby changing the distance between the two forklift frames. This allows for more stable movement of the items being transported. Simultaneously, the crossbar groove serves as a limit switch.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example 1: Please refer to Figures 1 to 5 : This utility model proposes an extendable and adjustable forklift frame, comprising: a support housing 1, which is mounted on a lifting device on the forklift; an extension structure 2 is provided on the support housing 1; the extension structure 2 includes a motor 201, which is mounted on the right end face of the support housing 1; the shaft of the motor 201 passes through the right side wall of the support housing 1; a bidirectional lead screw 202 is fixedly connected to the left end of the shaft of the motor 201; the left end of the bidirectional lead screw 202 is rotatably connected to the left side of the support housing 1; and the bidirectional lead screw 202 has two reverse threads arranged symmetrically on its exterior. The bidirectional lead screw 202 is externally connected to two sliders 203 via two reverse threads. The sliders 203 are slidably connected to the inside of the support housing 1. Each slider 203 has a forklift frame 3 fixedly connected to its front end. The two forklift frames 3 are equipped with a ranging component 4. The ranging component 4 includes a ranging ruler 401 and a U-shaped sliding sleeve 402. The ranging ruler 401 is fixedly connected to the upper end face of the left forklift frame 3, and the U-shaped sliding sleeve 402 is fixedly connected to the upper end face of the right forklift frame 3. The U-shaped sliding sleeve 402 is slidably connected to the ranging ruler 401. By adopting the above technical solution, when adjusting the distance between the two sides of the forklift frame 3, the staff can directly observe the red scale line aligned with the side of the U-shaped sliding sleeve 402 and the corresponding red size number, eliminating the need for the step of using tools such as a tape measure to assist in measurement, simplifying the operation, and greatly improving the convenience and efficiency of adjusting the distance between the forklift frame 3.

[0020] A protective box 101 is installed on the right end face of the support housing 1, and the protective box 101 is located outside the motor 201 to protect the motor 201.

[0021] The upper and lower sides of the support housing 1 are provided with strip rails 102. Each slider 203 has strip grooves 204 on both the upper and lower ends. The strip grooves 204 are slidably connected to the strip rails 102, which can guide the slider 203 and improve the stability of the slider 203 when sliding.

[0022] The measuring ruler plate 401 has strip-shaped scale grooves 403 and number grooves 404 evenly distributed on both the front and rear ends. The strip-shaped scale grooves 403 are located above the number grooves 404. The inside of the strip-shaped scale grooves 403 is sprayed with red scale lines, and the inside of the number grooves 404 is sprayed with red size numbers. The use of red makes it more eye-catching. By adopting the above technical solution, since the red scale marks and red size numbers are respectively set in the bar-shaped scale groove 403 and the number groove 404, the red scale marks and red size numbers cannot contact the inner wall of the U-shaped sliding sleeve 402, thus avoiding the phenomenon of wear of the red scale marks and red size numbers due to friction, and ensuring the long-term clarity and accuracy of the observation results.

[0023] Example 2, based on Example 1, such as Figure 1 and Figure 3 As shown, a baffle plate 301 is fixedly connected to the right end face of a forklift frame 3 on the left side, and a sliding groove 303 is provided on a forklift frame 3 on the right side, and the sliding groove 303 is slidably connected to the baffle plate 301. By adopting the above technical solution, when loading goods, the goods can be kept close to the vertical surface. The baffle 301 on the forklift frame 3 can effectively prevent the goods from sliding backward and limit the position of the goods, thereby improving the stability of the goods during transportation.

[0024] A T-shaped steel 302 is fixedly connected to the lower part of the rear end face of the forklift frame 3. The T-shaped steel 302 is located behind the lower slide groove 303. The T-shaped steel 302 provides significant structural reinforcement to the key stress area of ​​the forklift frame 3, effectively improving its overall rigidity and load-bearing strength.

[0025] The working principle of this embodiment is as follows: During use, when it is necessary to adjust the distance between the two forklift frames 3, it is only necessary to start the motor 201, which will rotate the bidirectional lead screw 202. Under the action of the two reverse threads on the outside of the bidirectional lead screw 202, the two sliders 203 move towards each other or away from each other at the same time, so that the distance between the two forklift frames 3 is adjusted, thereby adjusting the extension range of the two forklift frames 3. During the adjustment process, staff can directly observe the red scale line aligned with the side of the U-shaped sliding sleeve 402 and the corresponding red dimension numbers to determine the current distance between the two forklift frames 3. This eliminates the need for tools such as tape measures, simplifying the operation and greatly improving the convenience and efficiency of forklift frame 3 distance adjustment.

[0026] After adjustment, the goods are loaded through the forklift frames 3 on both sides. During the loading process, ensure that the goods are close to the baffles 301 on the forklift frames 3. The baffles 301 on the forklift frames 3 prevent the goods from slipping and stabilize the position of the goods, thereby improving the stability of the goods during transportation.
