Description

Technical Field

[0001] This utility model relates to the field of forklifts, and in particular to a forklift steering device that is easy to use. Background Technology

[0002] Forklifts are industrial material handling vehicles, referring to various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transport of palletized goods. The International Organization for Standardization (ISO / TC110) refers to them as industrial vehicles. They are commonly used for transporting large items in warehouses and are typically powered by internal combustion engines or batteries. The technical parameters of a forklift indicate its structural characteristics and working performance. Key technical parameters include: rated lifting capacity, load center distance, maximum lifting height, mast tilt angle, maximum travel speed, minimum turning radius, minimum ground clearance, wheelbase, and track width.

[0003] Forklifts are assembled from various components, and the forklift steering device is one such component. For example, Chinese Patent discloses a steering device that facilitates forklift steering (Publication No.: CN218360868U), which includes a steering bridge, a drive cylinder fixedly connected to the bottom of the steering bridge, a crank mounted on the output end of the drive cylinder, a bracket at the bottom of the drive cylinder, a transmission rod movably connected inside the bracket, and a transmission motor located on the back of the drive cylinder fixedly connected to the top of the bracket. This invention utilizes a transmission motor to drive a worm gear, which in turn drives a transmission rod. The transmission rod, via a helical gear, drives a cleaning brush. During its rotation, the cleaning brush cleans the connections between the crank, drive cylinder, and steering bridge, preventing mud and sand from affecting its operation. This solves the problem of existing steering systems lacking self-cleaning capabilities, which causes mud and water contamination on the steering surface when the forklift travels through mud and water, leading to friction from mud and sand particles and affecting steering performance. While this patent addresses the issue of existing steering systems lacking self-cleaning capabilities and causing mud and sand particles to rub against the steering surface when the forklift travels through mud and water, it does not allow for precise control of the cleaning location. This prevents users from cleaning mud and sand particles from other parts of the forklift steering system, causing inconvenience and affecting the normal operation of the forklift steering system.

[0004] Therefore, it is necessary to provide an easy-to-use forklift steering device to solve the above-mentioned technical problems. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Please refer to the following: Figures 1 to 5A user-friendly forklift steering device, comprising:

[0028] Forklift steering gear 1;

[0029] Cleaning mechanism 2 is installed on both sides of the bottom of the forklift steering gear 1;

[0030] The moving mechanism 3 includes a connecting shell 31. A motor 32 is fixedly connected to the bottom of the connecting shell 31. The output end of the motor 32 passes through the connecting shell 31 and extends into the interior of the connecting shell 31, where a helical gear 33 is fixedly connected. A helical gear 34 is provided on the left side of the top of the helical gear 33, and the helical gear 34 meshes with the helical gear 33. A positive and negative threaded rod 35 is fixedly connected inside the helical gear 34. Both sides of the surface of the positive and negative threaded rod 35 are threaded with a threaded sleeve 36. A positioning block 37 is fixedly connected to the top of the threaded sleeve 36. The top of the positioning block 37 passes through the connecting shell 31 and extends to the outside of the connecting shell 31. The gear specification of the helical gear 33 is smaller than that of the helical gear 34. By the fact that the gear specification of the helical gear 33 is smaller than that of the helical gear 34, the rotation speed can be reduced, avoiding accidents caused by the excessive rotation speed of the positive and negative threaded rod 35. The surface of the positioning block 37 is relatively smooth, avoiding large friction between the positioning block 37 and the connecting shell 31.

[0031] In the specific implementation process, refer to Figure 4 As shown, the forklift steering gear 1 includes a stabilizing housing 101. A steering shaft 102 is provided on the top of the stabilizing housing 101. The bottom of the steering shaft 102 passes through the stabilizing housing 101 and extends into the interior of the stabilizing housing 101 where a steering mechanism 103 is movably mounted. Pull plates 104 are movably connected to both sides of the steering mechanism 103. A connector 105 is movably connected to the side of the pull plate 104 away from the steering mechanism 103. A rotator 106 is fixedly connected to the top of the connector 105. The inner side of the rotator 106 is movably connected to the stabilizing housing 101, and a wheel retainer 107 is fixedly connected to the outer side of the rotator 106.

[0032] It should be noted that by setting the forklift steering gear 1, the steering of the wheels can be controlled. The user turns the steering shaft 102, which drives the steering mechanism 103 to move the pull plate 104. The pull plate 104 drives the connector 105 to move. The connector 105 drives the rotator 106 to rotate around the two sides of the stable shell 101 to adjust the steering angle of the wheel retainer 107. The wheel retainer 107 drives the wheels to turn.

[0033] In the specific implementation process, refer to Figure 2As shown, the cleaning mechanism 2 includes a pad 21, with cylinders 22 fixedly connected to both sides of the top of the pad 21. A lifting plate 23 is fixedly connected to the output end of the cylinder 22. A motor 24 is fixedly connected to the bottom of the lifting plate 23. A cleaning brush 25 is fixedly connected to the output end of the motor 24 through the lifting plate 23 and extending to the top of the lifting plate 23.

[0034] It should be noted that the cleaning mechanism 2 can be used to clean the forklift steering gear 1. The user drives the cylinder 22, which in turn moves the lifting plate 23 up and down. The lifting plate 23 then moves the motor 24 up and down, which in turn moves the cleaning brush 25 up and down, so that the cleaning brush 25 contacts the bottom of the forklift steering gear 1. After this is completed, the motor 24 is driven to rotate the cleaning brush 25, which then cleans the bottom of the forklift steering gear 1.

[0035] In the specific implementation process, refer to Figure 4 As shown, the front and back of the stabilizing shell 101 are fixedly connected to the connecting plate 4, and the bottom of the inner side of the connecting plate 4 is fixedly connected to the connecting shell 31.

[0036] It should be noted that by setting the connecting plate 4, the connecting shell 31 and the stabilizing shell 101 can be fixedly connected to prevent the connecting shell 31 and the stabilizing shell 101 from separating.

[0037] In the specific implementation process, refer to Figure 5 As shown, the top and bottom of the stabilizing shell 101 are provided with reinforcing plates 5, and the inner side of the reinforcing plates 5 is fixedly connected to the stabilizing shell 101.

[0038] It should be noted that by setting the reinforcing plate 5, the stability of the top and bottom of the stabilizing shell 101 can be increased, preventing deformation of the top and bottom of the stabilizing shell 101.

[0039] In the specific implementation process, refer to Figure 3 As shown, fixed bearings 6 are fixedly connected to both ends of the surface of the positive and negative threaded rod 35, and the surface of the outer ring of the fixed bearing 6 is fixedly connected to the inner wall of the connecting shell 31.

[0040] It should be noted that by setting the fixed bearing 6, the forward and reverse threaded rods 35 can be fixed to prevent them from shaking.

[0041] In the specific implementation process, refer to Figure 3 As shown, a slider 7 is fixedly connected to the bottom of the screw sleeve 36, and grooves 8 are provided on both sides of the bottom of the inner wall of the connecting shell 31. The grooves 8 are slidably connected to the slider 7.

[0042] It should be noted that by setting the slider 7 and the groove 8, the threaded sleeve 36 can be positioned to prevent the threaded sleeve 36 from rotating and wobbling when moving.

[0043] In the specific implementation process, refer to Figure 3 As shown, guide grooves 9 are provided on both sides of the top of the connecting shell 31, and the interior of the guide grooves 9 is slidably connected to the positioning block 37.

[0044] It should be noted that by setting the guide groove 9, the positioning block 37 can be guided to prevent the positioning block 37 from wobbling back and forth.

[0045] The working principle of the easy-to-use forklift steering device provided by this utility model is as follows:

[0046] When the user controls the forklift to turn, he turns the steering shaft 102. The steering shaft 102 drives the steering mechanism 103 to move the pull plate 104. The pull plate 104 drives the connector 105 to move. The connector 105 drives the rotator 106 to rotate around the two sides of the stable shell 101 to adjust the steering angle of the wheel retainer 107. The wheel retainer 107 drives the wheels to turn, thus turning the forklift. During the forklift's operation and handling, the forklift steering gear 1 will be contaminated with mud and sand particles, which will block the connection between the steering mechanism 103, the pull plate 104 and the connector 105.

[0047] During cleaning, the user drives cylinder 22, which drives lifting plate 23 to move up and down. Lifting plate 23 drives motor 24 to move up and down, and motor 24 drives cleaning brush 25 to move up and down, so that cleaning brush 25 contacts the bottom of forklift steering gear 1. After completion, drive motor 24, which drives cleaning brush 25 to rotate, and clean the mud and sand particles at the bottom of forklift steering gear 1 through cleaning brush 25.

[0048] After completion, the drive motor 32 drives the helical gear 33 to rotate. The helical gear 33 drives the helical gear 34 to rotate through the meshing of its teeth. The helical gear 34 drives the positive and negative threaded rod 35 to rotate. The positive and negative threaded rod 35 drives the threaded sleeve 36 to move inward through the meshing of its internal and external threads. The threaded sleeve 36 drives the positioning block 37 to move inward. The positioning block 37 drives the cleaning mechanism 2 to move left and right, so that the cleaning mechanism 2 cleans the mud and sand particles in other positions of the forklift steering gear 1.

[0049] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
