Abstract
Description
Technical Field
[0001] This utility model relates to the field of forklift mechanical structure technology, and in particular to a forklift frame. Background Technology
[0002] Forklifts are indispensable handling equipment in modern logistics warehousing and industrial production, playing a crucial role in loading, unloading, stacking, and short-distance transportation of goods. With the rapid development of the logistics industry and the continuous expansion of industrial production scale, higher demands are being placed on the frequency of forklift use and operational efficiency.
[0003] In traditional forklift technology, a fixed-gap forklift arm design is typically used to handle goods. This design involves directly mounting the forklift arms to the forklift frame, with the spacing not adjustable. When handling goods of different sizes, forklifts with multiple forklift arms of varying sizes are often required. Alternatively, there are more complex adjustment methods, such as manually disassembling and reassembling the forklift arms to change their relative positions, but these methods are cumbersome and time-consuming.
[0004] Traditional fixed-spacing forklift arms cannot flexibly adapt to the handling needs of goods of different sizes, which requires frequent changes of forklifts of different specifications in actual operations, greatly reducing operational efficiency. Utility Model Content
[0005] To address the problem that traditional forklift arms cannot flexibly adapt to the handling needs of goods of different sizes, this utility model provides a forklift frame.
[0006] The forklift frame provided by this utility model adopts the following technical solution:
[0007] A forklift frame includes a frame, two forklift arms mounted on the frame, and an adjusting mechanism for controlling the distance between the two forklift arms. A horizontal beam is integrally formed on the inner side of the frame. The adjusting mechanism includes a dual-axis motor mounted on the frame and a screw connected to the output end of the dual-axis motor. Each forklift arm has a loading / unloading section and a guide section. The screw and the guide section are threadedly connected, and the loading / unloading sections are detachably coupled to each other.
[0008] By adopting the above technical solution, a forklift frame is constructed by setting up a frame, forklift arms, and a spacing adjustment mechanism. The integrated molded crossbeam enhances the strength of the frame. The dual-axis motor drives the screw to rotate, which can adjust the spacing between the two forklift arms to accommodate goods of different sizes. The loading and unloading parts of the forklift arms are detachable for easy replacement and maintenance.
[0009] Optionally, the forklift arm includes a transverse arm and a longitudinal arm, the longitudinal arm is threadedly engaged with a screw, the longitudinal arm is slidably engaged with a crossbeam, and the transverse arm and the longitudinal arm are connected by a locking member.
[0010] By adopting the above technical solution, the forklift frame has adjustable forklift arms. The longitudinal arm slides along the crossbeam to adjust the spacing by using a dual-axis motor to drive the screw to rotate. The transverse arm and longitudinal arm are connected by locking parts, which facilitates installation and disassembly, and makes the use and maintenance of the forklift frame convenient.
[0011] Optionally, the locking component includes a guide strip and a locking bolt. The guide strip is disposed on the longitudinal arm, and a guide groove matching the guide strip is provided on one end of the transverse arm near the longitudinal arm. The guide strip and the guide groove slide together, and the locking bolt passes through the transverse arm, the guide strip and the nut in sequence to lock together.
[0012] By adopting the above technical solution, the forklift arm consists of a transverse arm and a longitudinal arm, which are connected by a locking mechanism, making it easy to disassemble and replace. The locking mechanism uses the sliding cooperation of guide strips and guide grooves to achieve the pre-positioning of the transverse arm and the longitudinal arm, and then uses locking bolts and nuts to lock the connection, which can ensure the stable connection between the transverse arm and the longitudinal arm and improve the overall stability of the forklift frame.
[0013] Optionally, friction textures are formed on the upper surface of the transverse arm, and a protective layer is provided on both the transverse arm and the longitudinal arm.
[0014] By adopting the above technical solutions, forming friction textures on the upper surface of the transverse arm can increase the friction between the goods and the forklift arm, preventing the goods from sliding during loading and unloading; setting protective layers on the transverse and longitudinal arms can protect the forklift arms and extend their service life.
[0015] Optionally, a through hole is provided on the longitudinal arm, and a V-shaped strip is integrally formed on the outer surface of the crossbeam along its axial direction, with the V-shaped strip and the through hole slidingly engaged.
[0016] By adopting the above technical solution, a V-shaped strip is integrally formed on the outer surface of the crossbeam. The V-shaped strip slides in conjunction with the through hole, allowing the longitudinal arm to slide stably along the crossbeam, thereby enhancing the stability and smoothness of the forklift arm movement.
[0017] Optionally, the end of the transverse arm away from the longitudinal arm forms a bevel structure.
[0018] By adopting the above technical solution, the inclined structure makes it easier for the forklift arm to insert under the goods, thus improving loading and unloading efficiency.
[0019] Optionally, the guide bar is a rod structure or a column structure, and the length of the guide bar is 1 / 4 to 1 / 3 of the length of the transverse arm.
[0020] By adopting the above technical solution and using guide bars with rod or column structure, the transverse arm can be accurately slid and positioned on the longitudinal arm. Furthermore, setting the length of the guide bar to 1 / 4 to 1 / 3 of the transverse arm length ensures a stable connection between the two, thereby improving the structural stability and reliability of the forklift frame.
[0021] Optionally, a baffle is provided on the side of the frame facing away from the forklift arm, and the cross-section of the baffle is triangular or trapezoidal.
[0022] By adopting the above technical solution, debris can be prevented from splashing during operation, thus improving safety.
[0023] In summary, this utility model has at least one of the following beneficial technical effects:
[0024] 1. The distance between the two forklift arms can be controlled by the adjustable distance mechanism, which can flexibly adapt to the handling needs of goods of different sizes, eliminating the need to frequently change forklifts of different specifications and improving operational efficiency.
[0025] 2. The loading and unloading parts of the forklift arm are detachable, making it easy to adjust and replace forklift arm components;
[0026] 3. The friction texture on the transverse arm increases the friction with the cargo, improving handling stability. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 The present invention will be described in further detail below.
[0034] This utility model discloses a forklift frame.
[0035] Reference Figure 1 The system includes a frame 1, two forklift arms 4 mounted on the frame 1, and an adjusting mechanism 2 for controlling the distance between the two forklift arms 4. The frame 1 supports and secures the components. The adjusting mechanism 2, working in conjunction with the forklift arms 4, controls the distance between the two forklift arms 4. This allows for flexible adjustment of the forklift arm distance according to the size of different goods, adapting to the handling needs of various goods and improving the forklift's operating efficiency. This is achieved because by changing the forklift arm distance through the adjusting mechanism 2, there is no need to equip the forklift with multiple forklift arms of different specifications or perform cumbersome manual adjustments, as is common with traditional forklifts.
[0036] See Figure 1 As shown, a crossbeam 3 is integrally formed on the inner side of the frame 1 in the horizontal direction. The crossbeam 3 is integrally formed on the inner side of the frame 1, so that the crossbeam 3 is tightly and firmly connected to the frame 1, which can provide stable support for subsequent components. The crossbeam 3 can be made of high-strength steel to ensure that it has sufficient strength and load-bearing capacity. Of course, in some application scenarios where weight is required, lightweight and high-strength materials such as aluminum alloy can also be used.
[0037] See Figure 4 As shown, the adjusting mechanism 2 includes a dual-axis motor 21 mounted on the frame 1 and a screw 22 connected to the output end of the dual-axis motor 21. The dual-axis motor 21 is mounted on the frame 1. When the dual-axis motor 21 is started, it will drive the screw 22 connected to its output end to rotate.
[0038] See Figure 1As shown, the forklift arm 4 has a loading / unloading section 41 and a guide section 42. The screw 22 and the guide section 42 are threadedly connected. The loading / unloading sections 41 are detachably connected to each other. The guide section 42 is threadedly connected to the screw 22. When the screw 22 rotates, it drives the guide section 42 to move along the screw 22, thereby realizing the movement of the forklift arm 4 and achieving the purpose of adjusting the spacing. The detachable loading / unloading section 41 allows for easy replacement with suitable parts according to different loading / unloading needs. For example, for heavier goods, a loading / unloading section 41 with a stronger load-bearing capacity can be replaced; for goods with special shapes, a suitable loading / unloading section 41 can be replaced.
[0039] See Figure 2 As shown, the forklift arm 4 includes a transverse arm 401 and a longitudinal arm 402. The longitudinal arm 402 is threadedly engaged with a screw 22 and slidably engaged with a crossbeam 3. The transverse arm 401 and the longitudinal arm 402 are connected by a locking member 5. The threaded engagement of the longitudinal arm 402 with the screw 22 allows the longitudinal arm 402 to move along the direction of the screw 22 when the screw 22 rotates. The slidably engaged crossbeam 3 provides guidance and support for the movement of the longitudinal arm 402, ensuring the stability of its movement. The connection between the transverse arm 401 and the longitudinal arm 402 via the locking member 5 facilitates adjustment or replacement of the combination of the transverse arm 401 and the longitudinal arm 402 according to actual conditions.
[0040] See Figure 2 and Figure 3 As shown, the locking component 5 includes a guide bar 51 and a locking bolt 53. The guide bar 51 is mounted on the longitudinal arm 402. A guide groove 52 matching the guide bar 51 is formed on one end of the transverse arm 401 near the longitudinal arm 402. The guide bar 51 and the guide groove 52 slide against each other. The locking bolt 53 passes through the transverse arm 401, the guide bar 51, and the nut in sequence for a locking fit. The sliding fit between the guide bar 51 and the guide groove 52 provides guidance for the connection between the transverse arm 401 and the longitudinal arm 402, ensuring accurate alignment during installation. The engagement of the locking bolt 53 and the nut securely connects the transverse arm 401 and the longitudinal arm 402 together. The guide bar 51 can be a rod structure or a column structure, with a length of 1 / 4 to 1 / 3 of the length of the transverse arm 401. This length ensures connection stability without adding unnecessary weight. The guide bar 51 can be made of stainless steel, which has good corrosion resistance and wear resistance.
[0041] See Figure 2As shown, friction patterns 6 are formed on the upper surface of the transverse arm 401, and a protective layer is provided on both the transverse arm 401 and the longitudinal arm 402. The friction patterns 6 can increase the friction between the goods and the transverse arm 401, preventing the goods from slipping during handling and improving handling safety. The protective layer can be a rubber coating, which can play a role in cushioning and protection, reducing wear and collision damage to the transverse arm 401 and the longitudinal arm 402 during use.
[0042] See Figure 2 As shown, a through hole is provided on the longitudinal arm 402, and a V-shaped strip 7 is integrally formed along its axial direction on the outer surface of the crossbeam 3. The V-shaped strip 7 and the through hole are in sliding engagement. The sliding engagement of the V-shaped strip 7 and the through hole provides precise guidance for the movement of the longitudinal arm 402 on the crossbeam 3, ensuring the straightness and stability of the movement of the longitudinal arm 402. The engagement of the V-shaped strip 7 and the through hole also increases the contact area between the longitudinal arm 402 and the crossbeam 3, distributing the force and improving the load-bearing capacity.
[0043] The end of the lateral arm 401 away from the longitudinal arm 402 forms a bevel structure. The bevel structure makes it easier for the forklift arm 4 to insert into the bottom of the goods, reduces insertion resistance, and improves operating efficiency.
[0044] See Figure 1 As shown, a baffle 8 is provided on the side of the frame facing away from the forklift arm 4. The baffle 8 has a triangular or trapezoidal cross-section. The baffle 8 serves a protective function, preventing goods from slipping backward during handling and ensuring the safety of operators. The triangular or trapezoidal cross-sectional structure gives the baffle 8 good stability and strength, enabling it to withstand a certain amount of impact.
[0045] The implementation principle of a forklift frame according to this utility model embodiment is as follows: The forklift frame, by setting an adjusting mechanism 2 on the frame frame 1, uses a dual-axis motor 21 to drive a screw 22 to rotate, thereby controlling the distance between the two forklift arms 4. This solves the problem that traditional forklifts with fixed-distance forklift arms 4 cannot flexibly adapt to the handling needs of goods of different sizes. Simultaneously, the forklift arms 4 employ a detachable loading / unloading section 41, adjustable transverse arms 401 and longitudinal arms 402, as well as friction textures 6, a protective layer, a sloped structure, and baffles 8, further improving the forklift's operating efficiency, safety, and applicability.
