Description

Fork support frame of forklift Technical Field The invention belongs to the technical field of forklifts, and particularly relates to a forklift fork supporting frame. Background The forklift is various wheeled transport vehicles for loading and unloading, stacking and short-distance transport operation of finished pallet cargoes, is flexible to drive and convenient to operate, and can transport cargoes to specified positions. When the forklift loads and unloads goods, the forklift runs beside the goods, a FORK (FORK LIFT) 400 is inserted from below the goods and supports the goods, a skid (Timber) can be paved below the goods according to the shape characteristics of the goods, and the goods can be further fixed by using a Sling (winding Bar). Then, the forklift walks to convey the goods to the unloading place, and the fork is pulled out from the lower part of the goods to unload the goods. In the process of loading, unloading, stacking and conveying cargoes on the tray by using the forklift, because the cargoes are supported by two forks, when the cargoes are not orderly put, the gravity center of the cargoes can be deviated, the cargoes are easy to drop in the forklift walking process, and the forklift is tipped over and other accidents. For example, in fig. 1a, the center of gravity is shifted to the right when the goods are placed too far to the right, and the goods are likely to fall off during the dragging and lifting process of the fork. For example, in fig. 1b, the goods are placed too far toward the front side, so that the center of gravity is shifted toward the front side, and the weight of the forklift body is balanced on the rear side, but if the goods are placed too far forward and the goods are heavy, the center of gravity of the whole forklift is possibly unstable, and a more serious tipping accident of the forklift body occurs. As shown in fig. 1c, when the goods are placed to the right and to the front, the goods are easy to drop, and the forklift may be tilted. Therefore, the placement of the cargoes on the fork is very important for the lifting transportation of the cargoes and the stability of the forklift, and if the gravity center of the cargoes can be timely adjusted, the falling risk of the cargoes can be reduced. However, when a forklift is currently used for transporting, it is generally difficult to adjust the position of the cargo to change the gravity center of the cargo after the cargo is lifted by using the fork, and a balancing weight is generally used to adjust the gravity center of the whole forklift. The balancing weight has increased fork truck's weight, has reduced fork truck walking efficiency, and can only reduce the risk that fork truck tumbles to can not effectively adjust the focus of goods, so can't reduce the risk that the goods dropped. In view of this, there is a need for a forklift that can adjust the center of gravity of the cargo so that the forklift can smoothly transport the cargo. Disclosure of Invention [ Problem ] In order to solve the above-described problems, an object of the present invention is to provide a fork support frame of a forklift, which can not only move and adjust the center of gravity of a load in a horizontal direction, but also rotate to adjust the center of gravity of the load, thereby enabling safe movement and transportation of the load. [ Technical solution ] A forklift fork support comprising a pair of support units mounted on a pair of forks, each support unit comprising: A pair of moving parts which are arranged at intervals at the upper ends of the forks and are used for moving the goods in the horizontal direction so as to adjust the gravity center of the goods; and the rotating parts are correspondingly arranged at the upper ends of the moving parts and are used for supporting the goods and rotating the goods to adjust the gravity center of the goods. Optionally, each moving part comprises a first moving bracket, a first sliding component arranged on the first moving bracket, a second moving bracket and a second sliding component arranged on the second moving bracket, The first movable bracket is fixedly arranged on the fork, the first sliding component comprises a first sliding rail and a first sliding block which is slidably arranged on the first sliding rail, the second movable bracket is fixedly arranged at the top end of the first sliding block, the second sliding component comprises a second sliding rail and a second sliding block which is slidably arranged on the second sliding rail, The sliding direction of the first sliding block is perpendicular to the sliding direction of the second sliding block.
