The rotary driving element 202 is connected to one end of the second forked tooth body 200, and can drive the second forked tooth body 200 to rotate around the second rotating shaft 201, so that the second forked tooth body 200 can be paid out relative to the supporting plate 21 or can be accommodated to be flush with the supporting plate 21, and therefore in the process that the duct piece 3 needs to be forked, turned over and transported, the second forked tooth body 200 is driven to be paid out relative to the supporting plate 21 through the rotary driving element 202, so that the second forked tooth body 200 and the supporting plate 21 jointly define an L-shaped accommodating space. After the turning and transferring of the duct piece 3 are completed, in the process that the duct piece 3 needs to be unloaded in a state that the arc-shaped inner side wall faces upwards, the second fork body 200 is driven to be flush with the supporting plate 21 through the rotary driving piece 202 so as to accommodate the second fork body 200, then two ends of the duct piece 3 are placed on the skid, and the forklift drives the forking frame 2 to retreat, so that the second fork body 200 is already accommodated, and in the retreating process of the forklift, the second fork body 200 can be prevented from rubbing the duct piece 3 without descending, so that the operation convenience of a forklift driver can be simplified, and the transfer efficiency of the duct piece 3 is improved.
In this embodiment, the rotary driving member 202 is a hydraulic motor, and on one hand, the hydraulic motor has the characteristics of stable driving and small volume compared with a hydraulic cylinder, and is more suitable for being used on a segment overturning device equipped in a forklift. On the other hand, be convenient for in the use, be connected rotary driving member 202 and fork truck from the hydraulic line of taking to the realization need not to dispose the power supply in addition as rotary driving member 202 with fork truck from the hydraulic line function of taking, is favorable to improving fork truck from the utilization ratio of the hydraulic line of taking and is favorable to simplifying the structure.
In the present embodiment, the number of the second prong 20 is two, and the two second prongs 20 are spaced apart from each other, so that the number of the second prongs 20 is minimized on the premise of ensuring forking performance.
In an alternative of this embodiment, the support frame 1 comprises a first support arm 10, a second hollow support arm and a stop beam 12.
Optionally, the first rotating shaft is connected to the second end of the first support arm 10 and the second end of the second support arm 11 respectively.
In this embodiment, first support arm 10 and second support arm 11 are hollow support arms, and the inserting groove is formed by the inside through-hole of hollow support arm to can adopt the channel-section steel as first support arm 10 and second support arm 11. In the actual use process, because the first supporting arm 10 and the second supporting arm 11 are inserted into the first fork tooth, the first supporting arm 10, the second supporting arm 11, the first rotating shaft and the limiting beam 12 are all in the horizontal plane, so that the fork moving frame 2 can be turned to the state that the supporting plate 21 is in the horizontal plane.
