With continued reference to fig. 2, in order to meet the high-density storage requirement in the warehouse logistics, the clearance between the rack 20 and the storage AGV cart is often small, the storage AGV cart travels in the roadway between the racks 20, and the driving wheels 14 installed at the bottom of the floating chassis 10 and the casters 15 at the front end and the rear end bear the complete machine and the container travels. The driving wheels 14 of the storage AGV trolley can increase the configuration of an internal contracting brake, and when the storage AGV trolley breaks down in a roadway, large equipment cannot be used for cleaning the storage AGV trolley. Therefore, the utility model provides a storage AGV pull equipment can be when the storage AGV dolly can not separate the band-type brake, fast and lightly pull the storage AGV dolly, makes things convenient for storage AGV dolly maintenance, improves production efficiency.

Referring also to FIG. 3, the dragging device for a warehousing AGV includes: a U-shaped base 30, the U-shaped base 30 having two towing forks 31 oppositely disposed and adapted to be inserted into both sides of the floating chassis 10. Two towing forks 31 are respectively positioned on both sides of the floating chassis 10.

Meanwhile, when the dragging equipment of the storage AGV moves and is dragged in cooperation with the storage AGV trolley, walking wheels are arranged on each dragging fork 31. In particular, each towing fork 31 is provided with at least two road wheels. The at least two road wheels include a first road wheel 311 provided at a front end of each towing fork 31 and a second road wheel 312 provided at a rear end of each towing fork 31. And, each road wheel is rotatably coupled to the corresponding towing fork 31 through a bearing. The inside of the travelling wheel is nested with a bearing, so that the rotation is smooth.

In addition, in order to guide and position the two towing forks 31 on both sides of the floating chassis 10, a guide wheel 313 for guiding the insertion direction of the floating chassis 10 is provided on each towing fork 31. The provided guide wheels 313 enable the dragging equipment of the storage AGV and the storage AGV to be fixed in relative position, and guide and limit are conducted. And, a plurality of guide wheels 313 are provided on each of the towing forks 31, and the plurality of guide wheels 313 are provided along the length direction of the towing fork 31. The plurality of guide wheels 313 facilitate handling and prevent scratching of the AGV cart appearance.

When the ends of the towing forks 31 on both sides are located on both sides of the hinged middle portion of the floating chassis 10, each towing fork 31 is provided with a jacking shaft 314 for tilting the driving wheel 14, specifically, two towing forks 31 have opposite inner side surfaces, and each jacking shaft 314 is arranged on the inner side surface of the corresponding towing fork 31. The oppositely disposed jacking shafts 314 are perfectly fitted to the hinged middle of the floating chassis 10. Each jack-up shaft 314 is disposed at an end of the corresponding towing fork 31 on the opening side of the U-shaped base 30. The jacking shaft 314 is located at the end of the towing fork 31 to increase the lever prying force.

Simultaneously in order to facilitate the AGV dolly of not releasing the band-type brake to pull and move, this storage AGV pull equipment still including pulling pole 32, pull pole 32 and U type base 30 articulated and lockable in first settlement position to should pull pole 32 and keep away from the one end symmetry of U type base 30 and be provided with the handle 33 of the artifical application of force of being convenient for. When the dragging rod 32 is hinged with the U-shaped base 30 and can be locked at a first set position, the dragging rod 32 is hinged with the U-shaped base 30 through the rotating shaft 34; a pin hole 37 is formed in one end, hinged to the U-shaped base 30, of the dragging rod 32, and a locking pin 35 matched with the pin hole 37 is detachably and fixedly connected to the U-shaped base 30; and the locking pin 35 is used to lock the drag lever 32 in the first set position. The dragging rod 32 rotates and can be connected to the U-shaped base 30 in a locking mode, and operation is facilitated when the storage AGV trolley is dragged.

And when the dragging rod 32 is locked at the first setting position, the length direction of the dragging rod 32 and the length direction of each dragging fork 31 form an included angle of less than 180 degrees.
