Description

Technical Field

[0001] This utility model belongs to the field of forklift frame technology, and in particular relates to a forklift frame structure with multi-directional reinforcing ribs. Background Technology

[0002] Forklifts are material handling equipment widely used in warehousing, logistics and industrial fields. Their structural design directly affects the stability, load-bearing capacity and efficiency of forklifts.

[0003] According to the publicly disclosed top frame structure for forklifts (publication number: CN 205773128 U), it includes a rear rectangular tube and side plates. The rear rectangular tube and side plates are connected by several evenly distributed grid plates. The side plates are in the shape of a "U". Several light holders are installed on the rear rectangular tube. The light holders are plate-shaped and have several mounting holes. A rear bracket is installed at the lower part of both ends of the rear rectangular tube. The rear bracket is bent downward at 90 degrees.

[0004] In the aforementioned application, the cooperation between components such as the light frame and the rear bracket makes it difficult to remove contaminants from the surface of the forklift frame, which leads to the risk of corrosion of the forklift frame and reduces the service life of the frame, and needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a forklift frame structure with multi-directional reinforcing ribs, which solves the problem of being unable to remove contaminants from the surface of the forklift frame through the cooperation between components such as scrapers and racks inside the forklift cleaning assembly.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] Furthermore, the rectangular groove is located on the displacement trajectory of the scraper, and the half gear and the rack mesh with each other. This design is beneficial for driving the rack to move when the half gear rotates.

[0009] Furthermore, a spring is fixedly connected to one end of the rack, and the end of the spring away from the rack is fixedly connected to the inner wall of the outer casing. The design of the spring facilitates the automatic reset of the rack when it is not driven.

[0010] Furthermore, a groove is provided on the inner wall of the outer casing, and a limiting rod is slidably connected to the inner wall of the groove. The end of the limiting rod away from the groove is fixedly connected to the side of the rack. The design of the groove and the limiting rod helps to limit the movement trajectory of the rack.

[0011] Furthermore, a vibration damping and retardant assembly is provided at the bottom of the forklift frame. The vibration damping and retardant assembly includes a cross plate, the top of which is located at the bottom of the forklift frame. A threaded groove is formed on the top of the cross plate, and a spring telescopic rod is fixedly connected to the bottom of the cross plate. A short rod is fixedly connected to the telescopic end of the spring telescopic rod, and a displacement block is fixedly connected to one end of the short rod. A blocking block is fixedly connected to the side of the spring telescopic rod, and a slot is formed on the top of the cross plate. Through the elasticity of the spring telescopic rod, vibration damping is achieved on the forklift frame, thereby reducing the impact when the forklift frame is subjected to an impact.

[0012] Furthermore, the blocking block is located on the displacement trajectory of the displacement block, and several blocking blocks are provided. Two spring telescopic rods are provided and are symmetrical to each other along the vertical central axis of the horizontal plate.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5This utility model is a forklift frame structure with multi-directional reinforcing ribs, including a forklift frame 1, a control console 2 provided on the side of the forklift frame 1, a forklift cleaning component 3 provided on the side of the forklift frame 1, the forklift cleaning component 3 including a housing 31, the side of the housing 31 being fixedly connected to the side of the forklift frame 1, a motor 33 being fixedly connected to the inner wall of the housing 31, a half gear 34 being fixedly connected to the output shaft of the motor 33, a rack 35 being slidably connected to the inner wall of the housing 31, a scraper 36 being fixedly connected to the side of the rack 35, and a rectangular groove 32 being opened on the side of the housing 31.

[0028] The rectangular groove 32 is located on the displacement trajectory of the scraper 36. The half gear 34 and the rack 35 mesh with each other. This design is beneficial to drive the rack 35 to move when the half gear 34 rotates.

[0029] A spring 37 is fixedly connected to one end of the rack 35. The end of the spring 37 away from the rack 35 is fixedly connected to the inner wall of the housing 31. The design of the spring 37 is conducive to the rack 35 automatically resetting when it is not driven.

[0030] A groove 38 is provided on the inner wall of the outer casing 31. A limit rod 39 is slidably connected to the inner wall of the groove 38. The end of the limit rod 39 away from the groove 38 is fixedly connected to the side of the rack 35. The design of the groove 38 and the limit rod 39 is beneficial to restricting the movement trajectory of the rack 35.

[0031] A vibration damping and retardant assembly 4 is provided at the bottom of the forklift frame 1. The vibration damping and retardant assembly 4 includes a horizontal plate 41. The top of the horizontal plate 41 is located at the bottom of the forklift frame 1. A threaded groove 42 is opened on the top of the horizontal plate 41. A spring telescopic rod 43 is fixedly connected to the bottom of the horizontal plate 41. A short rod 44 is fixedly connected to the telescopic end of the spring telescopic rod 43. A displacement block 45 is fixedly connected to one end of the short rod 44. A blocking block 46 is fixedly connected to the side of the spring telescopic rod 43. A slot 47 is opened on the top of the horizontal plate 41. Through the elasticity of the spring telescopic rod 43, the vibration of the forklift frame 1 is damped, so that the forklift frame 1 is reduced when it is subjected to impact.

[0032] The blocking block 46 is located on the displacement trajectory of the displacement block 45. Several blocking blocks 46 are provided, and two spring telescopic rods 43 are provided, which are symmetrical to each other along the vertical central axis of the horizontal plate 41. The design of several spring telescopic rods 43 is beneficial to improving the vibration reduction effect.

[0033] The slot 47 is located on the displacement trajectory of the blocking block 46. Several sets of vibration damping and deceleration components 4 are provided. The opening of the slot 47 is beneficial to not affecting the movement of the spring telescopic rod 43.

[0034] A specific application of this embodiment is as follows: Starting motor 33, which is a three-phase asynchronous motor capable of forward and reverse rotation, when motor 33 rotates forward, it drives half-gear 34 to rotate forward. The forward rotation of half-gear 34 drives half of the gear teeth to rotate forward. Half of the gear teeth mesh with rack 35. As half-gear 34 rotates, when half of the gear teeth rotate onto rack 35, it drives rack 35 to move. The movement of rack 35 pulls on spring 37, causing scraper 36 to move. Scraper 36 slides on the inner wall of rectangular groove 32. Scraper 36 is located at the bottom of forklift frame 1. When scraper 36 moves, it scrapes the bottom of forklift frame 1. The bottom of the forklift frame 1 is scraped to remove dirt. When half of the teeth on the half gear 34 do not rotate onto the rack 35, the rack 35 will automatically reset via the spring 37, and drive the scraper 36 to automatically reset, preventing the scraper 36 from continuously scraping. The cleaning system of the scraper 36 driven by the motor 33 can realize automated cleaning operations, reduce the time and labor of manual cleaning, and improve the working efficiency of the forklift. Especially in industrial settings, frequent cleaning operations can ensure that the forklift maintains a good working condition for a long time. By removing surface contaminants, the risk of corrosion can be reduced. Especially when working in humid or corrosive environments, regular cleaning helps to extend the service life of the frame.

[0035] A horizontal plate 41 and a threaded groove 42 are provided. Bolts pass through the threaded groove 42 and are then connected with nuts, allowing the horizontal plate 41 and the spring telescopic rod 43 to be installed at the bottom of the forklift frame 1. The spring telescopic rod 43 is telescopic, and the spring has a certain elasticity, allowing it to move up and down. When the forklift frame 1 is impacted and moves up and down, it will squeeze the spring telescopic rod 43, causing the telescopic end of the spring telescopic rod 43 to move up and down, buffering the impact on the forklift frame 1. When the spring telescopic rod 43 moves downward, it will drive the short rod 44 and the displacement block 45 to move downward. The blocking block 46 is located on the movement trajectory of the displacement block 45. When the displacement block 45 moves downward, it will contact the blocking block 46. When the displacement block 45 moves downward, it first contacts the arc surface of the displacement block 45, making... The spring telescopic rod 43 moves downwards relatively quickly. When the forklift frame 1 is not impacted, the spring telescopic rod 43 will rebound upwards. This rebound will cause the short rod 44 and the displacement block 45 to move upwards. The curved side of the displacement block 45 will first contact the blocking block 46, thus slowing down the rebound speed of the displacement block 45 with the spring telescopic rod 43. This reduces the impact on the forklift frame 1 when the spring telescopic rod 43 rebounds. The spring telescopic rod 43 can quickly extend and retract when the forklift frame 1 is impacted, providing a strong buffering effect. This can reduce the impact force on the forklift frame 1 and its internal components, reduce structural damage and fatigue, avoid overturning or loss of control due to violent shaking, and improve overall operational safety.

[0036] It should be noted that the forklift frame structure in this case has multi-directional stiffeners (not shown in the figure), which allows it to withstand complex loads from multiple directions, such as:

[0037] Vertical bending load: from the weight of the cargo and the mast itself; longitudinal torsional load: when the vehicle travels on uneven surfaces, the frame twists; lateral bending load: generated when turning or moving cargo laterally. Multi-directional stiffeners, by forming a dense mesh support structure, greatly improve the bending and torsional stiffness of the frame. This makes the frame less prone to deformation under heavy loads, ensuring the structural integrity and stability of the entire vehicle. In other words, during operation, the forklift frame is continuously subjected to dynamic loads and vibrations. Without reinforcing ribs, stress will concentrate in certain weak areas, which can easily lead to metal fatigue, cracks, or even breakage over time. Multi-directional reinforcing ribs can effectively disperse and transfer stress, avoiding excessive stress concentration. They divide large stress surfaces into multiple smaller areas, allowing the load to be evenly distributed across the entire frame, thus significantly extending the frame's service life. At the same time, by reinforcing key areas in the form of "ribs," multi-directional reinforcing ribs can achieve or even exceed the structural performance of thicker materials with relatively thinner materials. This helps engineers minimize structural weight while ensuring strength and safety, achieving lightweight design and improving the forklift's energy efficiency and load capacity. Furthermore, reinforcing ribs ensure the stability of the mounting bases for key components such as the mast, steering axle, and drive axle. If the frame rigidity is insufficient, slight deformation will occur when lifting heavy objects, which will affect the lifting accuracy of the mast and the vehicle's handling stability. A highly rigid frame provides a stable and reliable platform for all operations.
