Detailed Description
The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.
The rotary grabbing device shown in fig. 1-5 comprises a sliding sleeve 3, a traction rod 4 with one end positioned in the sliding sleeve 3, a sliding pin 41 connected with one end of the traction rod 4, a hook connected with the other end of the traction rod 4, and a pedal pin shaft mechanism connected with the sliding sleeve 3.
Sliding sleeve 3 connects on tractor 1, be equipped with connecting rod 21 on the commodity circulation trailer 2, the couple is colluded and is held in order to realize tractor 1 and the connection of commodity circulation trailer 2 on connecting rod 21. The hook includes a semi-closed groove-shaped hook 51 and a guide pin 52, the guide pin 52 being located at a side of the groove-shaped hook 51 and forming a guide groove therebetween.
The sliding sleeve 3 is provided with an arc-shaped sliding groove 30, the starting point of the arc-shaped sliding groove 30 is positioned on the longitudinal section of the sliding sleeve 3, the longitudinal section is parallel to the horizontal plane and penetrates through the central shaft of the sliding sleeve 3, and the end point of the arc-shaped sliding groove 30 is positioned at the top of the sliding sleeve 3. The sliding pin 41 is positioned in the arc-shaped sliding groove 30 to slide rotationally, so as to drive the traction rod 4 to translate and rotate, and then drive the hook to synchronously rotate 90 degrees horizontally.
One end of the traction rod 4 is connected with the sliding sleeve 3 through a first spring 7, and when the sliding pin 41 is located at the initial point, the first spring 7 is in a normal state, and the guide clamping groove is opposite to the connecting rod 21. When the slide pin 41 is positioned at the end point, the first spring 7 is in a compressed state, and the link 21 is caught in the groove-shaped hook 51.
The pedal pin shaft mechanism comprises a pin shaft 64, a pin shaft sleeve 65 sleeved outside the pin shaft 64, a second spring 66 positioned in the pin shaft sleeve 65 and wound on the pin shaft 64, and a pedal mechanism connected to the top of the pin shaft 64.
