The iron wheel and the loop bar of the device are limited in radial rotation, and can slightly move in the axial direction to avoid being stuck, so that the actual effect is not ideal.

Disclosure of Invention

The utility model aims to overcome the defects and shortcomings of the prior art, and provides a walking mechanism which is not easy to block during moving and is used for moving compact shelves.

In order to realize the purpose, the utility model adopts the technical proposal that: the simple walking mechanism of the compact shelf comprises a frame, wherein two parallel wheel shafts are arranged in the frame, the frame is provided with two parallel vertical faces, burr holes are punched in the vertical faces, two ends of each wheel shaft are respectively inserted into the burr holes corresponding to the vertical faces, the wheel shafts are fastened by the restoring force of burrs, at least two walking wheels are arranged on each wheel shaft, each walking wheel comprises a roller matched with a ground track and a transmission gear fixed with the roller, a bearing is arranged in an inner hole of each walking wheel, the bearing is sleeved on the wheel shaft, and the walking wheels can rotate relative to the wheel shafts.

The burr hole is formed by punching of a punching machine, and burrs are reserved on the periphery of the burr hole.

The burr is directed towards the outside of the frame.

The vertical surface is positioned on the body of the frame.

The frame is provided with two beams, and the vertical surface is positioned on the beams.

The utility model discloses a burr hole on shaft and the frame facade is fixed, and the drive gear and the gyro wheel of walking wheel are even as an organic whole, and motor or rocking handle pass through drive chain drive walking wheel, make the walking wheel rotatory around the shaft to drive intensive removal, more laborsaving when can reduce the demand to motor output or hand like this, the walking wheel is also difficult to block dead simultaneously more. Has the advantages of simple structure and low cost, and is suitable for various compact shelves.

Detailed Description

As shown in fig. 1 and 2, the utility model relates to a simple walking mechanism of compact shelf, which comprises a frame 30, wherein two parallel wheel shafts 20 are arranged in the frame 30. The frame 30 has two parallel vertical faces which, in the first embodiment, are located on the body of the frame 30. Burr holes 31 are punched on the vertical surfaces, two ends of the wheel shaft 20 are respectively inserted into the burr holes 31 of the corresponding vertical surfaces, and the wheel shaft 20 is fastened by the restoring force of burrs 32. The burr hole 31 is formed by punching with a punching machine, and burrs 32 are left on the periphery. The burrs 32 can also increase the strength of the burr holes 31, so that the burr holes 31 are not easy to deform, and the bearing capacity of the travelling mechanism is increased. The burr 32 is directed towards the outside of the frame 30, which facilitates the mounting of the axle 20.

At least two travelling wheels 10 are arranged on each wheel shaft 20, each travelling wheel 10 comprises a roller 12 matched with a ground track and a transmission gear 11 fixed with the roller 12, a bearing 13 is arranged in an inner hole of each travelling wheel 10, the bearing 13 is sleeved on the wheel shaft 20, and the travelling wheels 10 can rotate relative to the wheel shafts 20. A snap spring 14 is installed in an inner hole of the travelling wheel 10, and the snap spring 14 abuts against the end face of the bearing 13 to prevent the bearing 13 from moving axially. The transmission gear 11 and the roller 12 of the travelling wheel 10 are integrally cast. The transmission gear 11 of the travelling wheel 10 is driven by a transmission chain to rotate.

As shown in fig. 3, in the second embodiment, two beams 33 are provided on the frame 30, and the facade is located on the beams 33, which has the same effect as the first embodiment.

The utility model discloses a burr hole 31 on shaft 20 and the 30 facade of frame is fixed, and the drive gear 11 and the gyro wheel 12 of walking wheel 10 are even as an organic whole, and motor or rocking handle pass through drive chain drive walking wheel 10, make walking wheel 10 rotatory around shaft 20 to it removes to drive intensive, can reduce like this more laborsaving when demand to motor output or hand, and walking wheel 10 more also is difficult to block die simultaneously. Has the advantages of simple structure and low cost, and is suitable for various compact shelves.
