Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

Embodiment 1, a skid grabbing device, including setting up the axial walking unit in section of jurisdiction uninstallation region, the axial walking unit is last to be provided with the unit of snatching that is used for snatching the skid. The axial walking unit can move front and back in the segment unloading area, the axial walking unit can drive the grabbing unit to move synchronously when moving front and back, the grabbing unit can grab the skid in the segment unloading area, the skid is conveyed to a specific position under the drive of the axial walking unit, and the skid is taken down from the grabbing unit by operators standing on two sides of the trailer. The operating personnel need not the manual work and climbs to the pipe piece, just can realize the light of lumber skid snatchs, has avoided the emergence of incident.

Specifically, as shown in fig. 1 and 3, the axial traveling unit includes a traveling rail 6 disposed at the top of the trailer, and two ends of the traveling rail 6 are provided with anti-collision limiting blocks 11. The walking track 6 is arranged between the two segment crane beams 12, so that the structural arrangement of the existing trailer is not influenced, and the fore-and-aft movement of the segment crane 2 is not influenced. The walking mechanism 7 is arranged on the walking track 6 and comprises a driving motor and a walking wheel driven by the driving motor, the walking wheel is in rolling fit with the walking track 6, and the driving motor is connected with the control unit through a towing cable 10 matched with the walking track 6. The controller can be used for carrying out wired or wireless control on the control unit, and further controlling the forward and reverse rotation and the rotating speed of the driving motor.

The grabbing units are arranged on the travelling mechanism 7, and the travelling mechanism 7 drives the grabbing units to move synchronously when moving back and forth until the grabbing units are moved to the corresponding positions of the skid. As shown in fig. 2, the grasping unit includes an electric hoist 81 connected to the traveling mechanism 7, and an electric gripper 8 for grasping the skid is connected to a lifting rope 82 of the electric hoist 81. When the skid on the duct piece 4 needs to be grabbed, the lifting rope 82 lowers the electric mechanical claw 8 to the corresponding height, and then the electric mechanical claw 8 is controlled to automatically open and tightly grab the skid in a wired or wireless mode; the gripping force and the opening degree of the electric mechanical claw 8 can be adjusted according to the use requirement so as to adapt to the external dimension of the skid 5.

Further, the lifting rope 82 is connected with a balance beam 83, the electric mechanical claw 8 is connected with the lifting rope 82 through two ends of the balance beam 83, and the balance beam 83 is arranged to guarantee stability when the skid is grabbed and lifted.

Furthermore, the axial movement action of the travelling mechanism is electrically interlocked with the axial movement action of the segment crane 2 in the segment unloading area, so that the axial movement of the travelling mechanism and the axial movement of the segment crane are prevented from interfering or colliding accidentally.

Furthermore, a protective door 1 is arranged in a traveling section of the axial traveling unit, and the axial moving action of the segment crane 2, the axial moving action of the traveling mechanism and the opening and closing action of the protective door 1 are electrically interlocked. When an operator takes the skid on the electric mechanical claw 8 through the protective door 1, the electric interlocking can stop the segment crane 2 and the walking mechanism, and simultaneously, the acousto-optic alarm system is triggered to ensure the safety of the operator.

The utility model discloses a work flow as follows:

after the section of jurisdiction transports the position of the section of jurisdiction quick uninstallation device 3 to trailer 9, section of jurisdiction loop wheel machine 2 snatchs section of jurisdiction 4 back, to one section distance of the place ahead walking of trailer 9, behind the section of jurisdiction of section of jurisdiction loop wheel machine 2 degree left side section of jurisdiction, operating personnel starts through manual or remote control mode the utility model discloses. Firstly, the walking mechanism is controlled to move to the position of the duct piece 4 along the walking track 6, then the electric crane 81 is controlled to reduce the electric mechanical claw 8 to the position of the skid 5, the claw of the electric mechanical claw 8 grabs the first skid and conveys the first skid to the protective door 1 of the operation area of an operator.
