Description

Technical Field

[0001] This utility model relates to the field of stacker locomotive frame technology, specifically a high-strength, lightweight electric stacker locomotive frame. Background Technology

[0002] Forklifts are ideal equipment for palletized loading and unloading in high-bay warehouses and workshops. They are widely used in industries such as petroleum, chemical, pharmaceutical, textile, military, paint, pigment, and coal, as well as in ports, railways, freight yards, and warehouses. This equipment plays a vital role in improving loading and unloading efficiency and reducing labor intensity.

[0003] The existing technology has the following defects or problems: Existing technology publication number CN221370470U relates to the field of forklift chassis technology and discloses a high-strength, lightweight electric forklift chassis, including a chassis body. The front of the chassis body has a first threaded hole, and a first fixing bolt is threaded into the first threaded hole. This high-strength, lightweight electric forklift chassis, through the cooperation of an electric push rod, a push plate, and a moving plate, allows the electric push rod to extend and retract, moving the push plate, which in turn moves the moving plate, thus adjusting the applicable range of the device. Through the cooperation of a shock-absorbing spring and a shock-absorbing pad, when the shock-absorbing pad is impacted, the energy generated by the impact is transmitted to the shock-absorbing spring, which then eliminates the energy, thereby improving the protective performance of the device and extending its service life.

[0004] The aforementioned equipment is difficult to stabilize during use, which can lead to shaking or tilting, increasing operational risks and potentially posing safety hazards to operators. Furthermore, in existing technologies, some forklift frames lack effective cushioning measures, allowing them to be subjected to excessive impact forces during installation or use, resulting in structural deformation, cracks, or other forms of damage. This not only affects the normal operation of the equipment but may also shorten its service life.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-strength, lightweight electric stacker frame, solving the current problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-strength, lightweight electric stacker chassis frame, comprising a chassis body, wherein multiple support rods are fixedly connected inside the chassis body, and buffer components are respectively provided at the top ends of the multiple support rods; auxiliary support plates are fixedly connected to the front and rear ends of the right side of the chassis body; two connecting blocks are fixedly connected to the opposite sides of the two auxiliary support plates; hydraulic connecting rods are fixedly connected inside the two connecting blocks; a fixing bolt is rotatably connected to the output end of the hydraulic connecting rod; a recess is fixedly connected to the outside of the fixing bolt; a connecting plate is fixedly connected to the bottom end of the recess; an opening is provided at the bottom front side of the connecting plate; multiple auxiliary wheels are rotatably connected inside the opening; and movable wheels are respectively provided at the four corners of the bottom end of the chassis body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-4In this embodiment: a high-strength lightweight electric stacker frame includes a frame body 1. Multiple support rods 2 are fixedly connected inside the frame body 1. Buffer components are respectively provided at the top of the multiple support rods 2. Auxiliary support plates 3 are fixedly connected to the front and rear ends of the right side of the frame body 1. The adjacent sides of the two auxiliary support plates 3 are fixedly connected to the front and rear ends of the right side of the frame body 1. Two connecting blocks 4 are fixedly connected to the distant sides of the two auxiliary support plates 3. Hydraulic connecting rods 5 are fixedly connected inside the two connecting blocks 4. The right ends of the multiple hydraulic connecting rods 5 are fixedly connected to the left inner wall of the connecting block 4. The output end of the hydraulic connecting rod 5 is rotatably connected to a fixing bolt 7. The outside of the fixing bolt 7 is fixedly connected to the inner wall of a recess 6. The outside of the fixing bolt 7 is fixedly connected to the recess 6. A connecting plate 8 is fixedly connected to the bottom end of the recess 6. An opening 9 is opened at the front bottom end of the connecting plate 8. Multiple auxiliary wheels 10 are rotatably connected inside the opening 9. Moving wheels 16 are respectively provided at the four corners of the bottom end of the frame body 1.

[0025] In this embodiment, when the hydraulic system drives the hydraulic linkage 5 to extend and retract, the concave block 6 will produce corresponding displacement and angle changes as the fixing bolt 7 moves, and move the connecting plate 8, so that the auxiliary wheel 10 contacts the ground. The auxiliary wheel 10 can share part of the weight of the frame, reduce the load and wear of the moving wheel 16, and at the same time provide better flexibility and maneuverability, enabling the forklift to be positioned and operated more accurately.

[0026] Example 2

[0027] like Figure 1 - Figure 4 As shown, multiple buffer components include support rods 2. The front and rear sides of the multiple support rods 2 are fixedly connected to the inner walls of the front and rear ends of the vehicle frame body 1, respectively. A buffer groove 11 is opened inside the support rod 2. Multiple damping rods 12 are fixedly connected inside the buffer groove 11. Springs 13 are respectively sleeved on the outside of the multiple damping rods 12. The top ends of the multiple springs 13 are in contact with the bottom end of the limiting plate 14. The top ends of the multiple damping rods 12 are fixedly connected to the limiting plate 14. The outside of the limiting plate 14 is slidably connected to the inner wall of the support rod 2. A buffer plate 15 is fixedly connected to the top end of the limiting plate 14. The outside of the buffer plate 15 is in contact with the inner wall of the top end of the support rod 2.

[0028] In this embodiment, when an external force is applied to the buffer plate 15, the buffer plate 15 will transmit the force to the limiting plate 14. The limiting plate 14 will slide downward on the inner wall of the support frame rod 2, compressing the spring 13. Due to its elastic characteristics, the spring 13 will generate an elastic force opposite to the external force, attempting to restore its original shape, thereby buffering and absorbing the external force and reducing the impact of the impact force on the frame body 1 and the entire stacker structure. During the movement of the limiting plate 14, a damping force is generated. This damping force cooperates with the elastic force of the spring 13. The presence of the damping force can control the extension and retraction speed of the spring 13, preventing the spring 13 from generating violent oscillations due to excessive compression or rebound, making the buffering process more stable and controllable.

[0029] The working principle and usage process of this utility model: When the operator drives the hydraulic linkage 5 to extend and retract through the hydraulic system, the concave block 6 will produce corresponding displacement and angle changes with the movement of the fixing bolt 7, and move the connecting plate 8, so that the auxiliary wheel 10 contacts the ground. The auxiliary wheel 10 can share part of the weight of the frame, reduce the load and wear of the moving wheel 16, and at the same time provide better flexibility and maneuverability, enabling the forklift to be positioned and operated more accurately. The frame body 1 and its internal support frame rod 2 jointly bear and distribute these forces, ensuring the overall structural stability and safe operation of the vehicle. When an external force is applied to the buffer plate 15, the buffer plate 15 will transmit the force to the limiting plate 14. The limiting plate 14 will slide downward on the inner wall of the support frame rod 2, compressing the spring 13. Due to its elastic characteristics, the spring 13 will generate an elastic force opposite to the external force, attempting to restore its original shape, thereby buffering and absorbing the external force and reducing the impact of the impact force on the frame body 1 and the entire stacker structure. During the movement of the limiting plate 14, a damping force is generated. This damping force works in conjunction with the elastic force of the spring 13. The presence of the damping force can control the extension and retraction speed of the spring 13, preventing the spring 13 from generating violent oscillations due to excessive compression or rebound, making the buffering process more stable and controllable.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
