[0002] Forklifts are industrial handling vehicles, which refer to various wheeled handling vehicles that load and unload, stack and transport palletized goods over short distances. The International Organization for Standardization ISO / TC110 calls them industrial vehicles. They are often used for transporting large objects in warehouses and are usually powered by fuel engines or batteries.

[0003] In order to facilitate loading and unloading, the forks can rotate relative to the forklift. However, when the forks of the forklift are fully loaded with goods, the forks of the traditional fork frame assembly structure tilt to one side due to the gravity of the goods, which can easily cause the loaded goods to slide. Therefore, in order to prevent the forks from tilting downward, the only way is to reduce the weight of the goods or limit the stacking height of the goods, which reduces the efficiency of the forklift loading and unloading.

[0007] Furthermore, a lateral shift mechanism is provided in the mounting frame, and the lateral shift mechanism includes a bidirectional oil cylinder fixedly connected to the mounting frame, and a clamping assembly is provided on each output end of the bidirectional oil cylinder. The bidirectional oil cylinder drives the fork to move along the axial direction of the rotating shaft through the clamping assembly.

[0008] Furthermore, the clamping assembly includes a first baffle fixedly connected to the output end of the cylinder, a connecting rod is fixedly connected to the first baffle, an arc groove corresponding to the connecting rod is opened on the fork, the connecting rod passes through the arc groove and is fixedly connected to the second baffle.

[0009] Furthermore, a limit block for limiting the rotation of the fork is fixedly provided in the mounting frame.

[0010] Furthermore, the limiting block is arranged in an arc shape on a side close to the forklift.

[0011] Furthermore, two support frames are fixedly installed in the mounting frame, and the two support frames are rotatably connected to the rotating shaft and are symmetrically arranged.

[0012] In the above technical solution, the anti-tipping fork frame assembly provided by the utility model has the following beneficial effects:

[0013] By setting up the anti-tipping assembly, the motor drives the worm wheel to rotate through the worm, and the rotation of the worm wheel drives the fork to rotate through the convex strip on the rotating shaft, so that the forklift can control the inclination degree of the fork, and due to the self-locking of the worm wheel, when the inclination degree of the fork is adjusted, the fork will maintain the inclination, so that the goods on the fork remain stable during transportation.

[0025] The lifting mechanism can realize the lifting of the fork 22 through the existing technologies such as the cooperation of a screw rod, an electric push rod, a hydraulic rod, a sprocket and a chain, which will not be described in detail.

[0026] By means of the anti-tipping assembly, the motor 32 drives the worm wheel 3 to rotate through the worm 31, and the rotation of the worm wheel 3 drives the fork 22 to rotate through the convex strip 21 on the rotating shaft 2, so that the forklift can control the inclination degree of the fork 22, and due to the self-locking of the worm wheel 3 and the worm 31, when the inclination degree of the fork 22 is adjusted, the fork 22 will maintain the inclination, so that the goods on the fork 22 remain stable during transportation.

[0027] Furthermore, a lateral shift mechanism is also provided in the mounting frame 1, and the lateral shift mechanism includes a bidirectional cylinder 4 fixedly connected to the mounting frame 1, and a clamping assembly is provided on each output end of the bidirectional cylinder 4.

[0029] The output end of the two-way oil cylinder 4 extends to drive the first baffle 41 to move, and the movement of the first baffle 41 drives the fork 22 to move along the axial direction of the rotating shaft 2, and the two forks 22 move away from each other; the output end of the two-way oil cylinder 4 retracts to drive the second baffle 43 to move, and the movement of the second baffle 43 drives the fork 22 to move along the axial direction of the rotating shaft 2, and the two forks 22 move closer to each other; when the fork 22 rotates with the rotating shaft 2, the arc groove 44 rotates, so that the connecting rod 42 can still be connected to the second baffle 43 when the fork 22 rotates. The arc groove 44 can limit the rotation range of the fork 22.

[0030] Furthermore, a limit block 11 for limiting the rotation of the fork 22 is fixedly provided in the mounting frame 1. The limit block 11 is arranged in an arc shape on the side close to the forklift.

[0032] Working principle: the motor 32 drives the worm wheel 3 to rotate through the worm 31, and the rotation of the worm wheel 3 drives the fork 22 to rotate through the convex strip 21 on the rotating shaft 2, so that the forklift can control the inclination of the fork 22, and due to the self-locking of the worm wheel 3 and the worm 31, when the inclination of the fork 22 is adjusted, the fork 22 will maintain the inclination, so that the goods on the fork 22 remain stable during transportation; the output end of the two-way oil cylinder 4 extends to drive the first baffle 41 to move, and the movement of the first baffle 41 drives the fork 22 to move along the axial direction of the rotating shaft 2, and the two forks 22 move away from each other; the output end of the two-way oil cylinder 4 retracts to drive the second baffle 43 to move, and the movement of the second baffle 43 drives the fork 22 to move along the axial direction of the rotating shaft 2, and the two forks 22 move closer to each other; when the fork 22 rotates with the rotating shaft 2, the arc groove 44 rotates, so that the connecting rod 42 can still be connected to the second baffle 43 when the fork 22 rotates. The arc groove 44 can limit the rotation range of the fork 22. The utility model can adjust the tilt angle of the forklift to facilitate loading and unloading, and can maintain the tilt after adjustment to prevent the fork 22 from tipping over. The device has a simple structure and is easy to use. The design is compact and reasonable, and the space occupied by the fork 22 is reduced.
