Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given.

As shown in fig. 1-3, the reciprocating type opening and closing fork lifter comprises a fixed frame 1 composed of four upright posts 11, wherein lifting frames 2 are respectively arranged on two sides of the fixed frame 1, a rotating motor 21 and rotating shafts 22 respectively positioned on two sides of the rotating motor 21 are arranged on the lifting frames 2, a driving sprocket 23 is arranged on an output shaft of the rotating motor 21, driven sprockets 24 are respectively arranged at the upper ends of the two rotating shafts 22, the driving sprocket 23 and the driven sprockets 24 are connected through a transmission chain, and fork plates 25 are respectively arranged at the lower ends of the two rotating shafts 22; and the fixed frame 1 is also provided with a lifting mechanism 3 for driving the lifting frame 2 to lift.

Whole fixed frame 1 adopts the welding integral type structure, and is firm stable, simple to operate.

The hoisting frame 2 and the components on the hoisting frame 2 can be symmetrically arranged at two sides, the structure is simple, and the processing and the installation are easier.

The lifting frame 2 is connected between the two upright posts 11 in a sliding manner, and the rotating shaft 22 is connected with the lifting frame 2 through a bearing. The structure enables lifting and rotating to be more stable, and bearing capacity is improved.

One of the rotary shafts 22 has a top end passing through the lifting frame 2 and fixedly connected with a pointer 26. The pointer 26 is grasped as the rotary shaft 22 is rotated, and the position of the fork plate 25 and the condition of the fork of the load can be more visually recognized.
