Description

Technical Field

[0001] The utility model relates to the technical field of forklifts, in particular to an anti-rollover structure of an electric forklift. Background Art

[0002] Forklifts play a very important role in the logistics system of an enterprise. They are the main force in material handling equipment and are widely used in various sectors of the national economy, such as stations, ports, airports, factories, warehouses, etc. Due to different applications, forklifts also have various functional forms. Some forklifts are usually designed to be electric to facilitate people's transportation. This type of electric forklift mainly uses a motor to drive a driving wheel to drive the body to move. Usually, in order to prevent the forklift from being stable and effective during travel and not tipping over, a bracket will be set on the forklift to prevent the forklift from tipping over. However, generally speaking, the bracket structure is relatively simple, and it is easy to deform in actual use, and it is easy to wear after contacting the bottom surface, which affects the service life;

[0003] Under the prior art, a Chinese patent application numbered "201520040444.8" discloses an anti-rollover electric forklift, the technical solution of which includes a body, a connecting frame, and a driving mechanism, wherein the driving mechanism drives the body to move through the connecting frame, and the driving mechanism includes a driving wheel, a supporting frame is fixedly provided on the connecting frame, and a roller is fixedly provided at the bottom of the supporting frame, and the lowest point of the roller is flush with the lowest point of the driving wheel; the original bracket is changed into a supporting frame with a roller, and the roller can play a supporting effect, and the lowest point of the roller is flush with the lowest point of the driving wheel to ensure the overall stability;

[0004] The above patent can ensure the stability of the forklift during its movement to a certain extent, but in actual use, its rollers, brackets and forklift are all rigidly fixed. After long-term use, there will be a certain error between the support parts of the forklift body and the support parts of the rollers on both sides, resulting in that in daily life, the rollers on both sides may not contact the ground at the same time, and cannot form a certain fixed support to prevent rollover. For this reason, we propose an anti-rollover structure for an electric forklift to solve the above problem. Utility Model Content

One end of the fixed plate 208 close to the receiving platform 101 is fixedly connected to the moving seat 205. The support wheels 207 at the bottom of the receiving platform 101 support and stabilize both sides of the forklift body 1 to improve its stability. The multiple support wheels 207 are built with elastic parts to ensure that the support wheels 207 can always keep in contact with the ground during use and will not make themselves lower than the support parts of the forklift body 1 after use.

[0025] Furthermore, a connecting window 209 is provided on one side of the assembly sleeve 202 near the center of the receiving platform 101, and a trigger plate 210 matching with the movement seat 205 is fixedly connected to the side of the movement seat 205 near the connecting window 209. The end of the trigger plate 210 away from the movement seat 205 passes through the connecting window 209 and extends to the bottom of the receiving platform 101. The trigger plate 210 is slidably connected to the inner wall of the connecting window 209.
