[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1-3 As shown, a narrow aisle forklift anti-rollover structure includes a supporting slide plate 1, which is located directly below the fork 3 and is used to provide support for the fork 3.

[0020] Specifically, the forklift also includes a chassis 2 and a fork 3. The chassis 2 is provided with a slide groove 21 arranged along the length direction. The tail end of the fork 3 is movably set in the slide groove 21. The support slide plate 1 can also be slidably set in the slide groove 21 and can move in the horizontal direction with the fork 3 to support the fork 3. In this process, since the support slide plate 1 is always directly below the fork 3, the support point can be adjusted instantly, which can effectively support the support slide plate 1 and prevent the forklift from tipping over.

[0021] In order to achieve synchronous movement of the fork 3 and the supporting slide 1, the forklift also includes a door frame 4. The bottom of the door frame 4 is provided with a downwardly protruding connecting portion 41, and the connecting portion 41 is movably arranged in the slide groove 21. One end of the fork 3 and the supporting slide 1 are both connected to the connecting portion 41, and the bottom of the other end of the supporting slide 1 is provided with a supporting wheel 11 that abuts against the ground. When the fork 3 is driven to move by the door frame 4, the supporting slide 1 can be driven to move synchronously to ensure that the fork 3 is always located directly below the supporting slide 1, wherein the support wheel 11 plays a role of rolling support.

[0022] In order to increase the forking range of the fork 3, the fork 3 is liftably arranged on the door frame 4. When the fork 3 is lowered to its lowest position, it can fit with the top of the supporting slide plate 1. In the process of the fork 3 forking the goods, the horizontal position of the fork 3 can be adjusted first, and then the height of the fork 3 can be adjusted. After forking the goods, the fork 3 is lowered to the supporting slide plate 1 and supported by the supporting slide plate 1.

[0023] In order to improve the stability of the lateral movement of the gantry 4, two slide grooves 21 are provided. The two slide grooves 21 are symmetrically arranged on the chassis 2 and correspond to the two forks 3 one by one. The two connecting parts 41 extend into the two slide grooves 21 respectively. The two symmetrically arranged connecting parts 41 move simultaneously, and the movement stability of the gantry 4 is better. Specifically, both sides of the slide groove 21 are provided with guide rails 211 arranged along the arrangement direction of the slide groove 21, and both outer sides of the connecting part 41 are provided with guide wheels 411. The two guide wheels 411 are respectively connected to the two guide rails 211, and the gantry 4 is driven to move through the cooperation of the guide wheels 411 and the guide rails 211.

[0024] In order to limit the position of the connecting part 41 and prevent it from escaping from the slide groove 21, a limit block 212 is provided at the front end of the guide rail 211. The limit block 212 can abut against the guide wheel 411 to limit the connecting part 41 from escaping from the slide groove 21. That is, when the guide wheel 411 abuts against the limit block 212, the door frame 4 and the fork 3 are at the frontmost position.

[0025] In order to prevent the guide wheel 411 from derailing due to vibration, limit plates 213 are provided on both sides of the slide groove 21. The limit plates 213 are located directly above the guide rail 211 and can abut against the top of the guide wheel 411 to limit the guide wheel 411 from continuously moving upward and prevent it from escaping from the slide groove 21.
