Synchronous adjustment mechanism for forklift frame and regulation method

Abstract

The invention discloses a synchronous adjustment mechanism for a forklift frame and a regulation method. The synchronous adjustment mechanism comprises oil cylinders symmetrically and fixedly arranged on two side columns of the frame. Each oil cylinder comprises a cylinder bottom, a cylinder cover and a piston rod connected with a piston into a whole. The cylinder covers are embedded cylinder covers. The side portion of each piston rod is connected with a frame support, fixedly arranged on the frame, through a fastening bolt. An interception buffer mechanism is arranged at each cylinder bottom and comprises a buffer column fixed to the center position of the corresponding cylinder bottom. A buffer sleeve is arranged on the periphery of each buffer column in a sleeving manner. The buffer sleeves are embedded in inner cavities of the pistons. Floating blocking pieces are arranged at the positions of oil injection openings of the pistons located on the tops of the buffer sleeves. By means of the device, the production efficiency and the oil cylinder reliability are improved, the phenomenon that because the cylinder covers are rotated, sealing pieces are damaged and leak oil is avoided, fault points of the forklift frame are reduced, and the forklift product quality is improved. According to the device, the descending interception buffer mechanisms are added to the cylinder bottoms, striking noise and vibration during oil cylinder descending are eliminated, and the operation comfort of the forklift frame is improved.

Description

technical field [0001] The invention belongs to the technical field of forklifts, and in particular relates to a synchronous adjustment mechanism and an adjustment method of a forklift mast. Background technique [0002] The forklift mast generally adopts a wide-view mast structure. This type of mast is designed with two oil cylinders responsible for driving the lifting of the cargo, which are arranged on the left and right sides of the mast, so that the middle position of the mast can be vacant. Come out, so that the driver's operating field of vision is unobstructed. [0003] The two oil cylinders drive the inner mast of the forklift to rise at the same time, thereby driving the goods to rise. In order to ensure the stability and safety of the goods at the high position, it is necessary to require the two oil cylinders to move synchronously and have the same stroke, so that the inner mast and the goods cannot be skewed when the oil cylinders are in place. Similarly, when...

Problems solved by technology

[0007] The above-mentioned synchronous adjustment method is time-consuming, labor-intensive, low in work efficiency, and labor-intensive. Rotating the cylinder head at the same time may easily cause misalignment or damage of the sealing ring in the cylinder head, resulting in new oil leakage points.
