The invention discloses a device for adjusting the brake performance during forward movement of a forklift portal frame in the technical field of forklifts, which comprises a forklift body, supporting legs are arranged at the two ends of the front side of the forklift body, the supporting legs on the two sides are connected with the portal frame, a pallet fork is arranged on the portal frame, front wheels are arranged on the supporting legs on the two sides, and the front wheels are connected with the forklift body. Driving wheels are arranged at the two ends of the rear side of the forklift body; pressure detection assemblies are arranged at the left ends of the front side and the rear side of the forklift body and the right ends of the sides, away from each other, of the supporting legs on the two sides. Through the processing of a central processing unit, an electric guide rail drives a placement groove to move backwards, a balancing weight moves along with the placement groove, and the wheel load of a driving wheel is increased, so that the ratio of pressure data detected by pressure sensors on the front side and the rear side is approximately the same as the ratio when a portal retracts; therefore, when a forklift worker forgets to withdraw the forward-moving portal frame and drives, the situation that the gravity center moves forwards is avoided, the wheel load of the driving wheels is improved, the driving wheels are not prone to slipping, and the braking performance is improved.
本发明公开了叉车技术领域的一种叉车门架前移时的制动性能调节装置,包括,叉车本体,所述叉车本体的前侧两端均设置有支腿,两侧支腿均与门架连接,所述门架上设置有货叉,两侧支腿上均设置有前轮,所述叉车本体的后侧两端均设置有驱动轮;所述叉车本体前后两侧的左端和两侧支腿相互远离一侧的右端均设置有压力检测组件;通过中央处理器处理,使得电动导轨带动放置槽向后移动,使得配重块跟随移动,增加驱动轮的轮载,从而使得前后两侧压力传感器检测到的压力数据比值与门架缩回时之间的比值接近相同,从而叉车工人在忘记收回前移的门架就进行行驶时,避免出现重心前移的情况,从而提高了驱动轮的轮载,不容易打滑,从而提高了制动性能。
