Referring to fig. 1, fig. 1 is a schematic structural diagram of a traveling mechanism 100 according to the present application. The traveling mechanism 100 in the present application may be provided in a stereoscopic warehouse for carrying an object. Wherein, a bearing assembly (not shown) for receiving the object may be disposed on the traveling mechanism 100, and the object is carried by the traveling mechanism 100, so that the object is circulated in each space region of the stereoscopic warehouse or enters and exits the stereoscopic warehouse.

In this embodiment, the running gear 100 may include a ground rail 110 and a lower cross member 120. Wherein, the lower beam 120 is erected on the ground rail 110 and can move along the ground rail 110. The lower end surface 121 of the lower cross beam 120 is provided with a groove 123, and the groove 123 is matched with the upper end part 112 of the ground rail 110, so that the upper end part 112 of the ground rail 110 can go deep into the groove 123 and abut against the inner wall of the groove 123, and further the lower end surface 121 of the lower cross beam 120 is lower than the upper end surface 1123 of the ground rail 110.

Therefore, the traveling mechanism 100 in the present embodiment enables the upper end portion 112 of the ground rail 110 to penetrate into the lower cross member 120 by providing the groove 123 matched with the ground rail 110 on the lower cross member 120, so that the installation distance between the lower cross member 120 and the ground rail 110 is shortened. In this way, when the traveling mechanism 100 in this embodiment transports an object, the transporting assembly disposed on the lower cross beam 120 can receive the object at a lower height, so that the space utilization rate of the warehouse can be improved.

Further, with continued reference to fig. 1, the ground rail 110 may be directly disposed on the ground. The lower end 111 of the ground rail 110 is fixedly arranged on the ground, and the cross section of the upper end 112 is arranged in a "T" shape and is connected with the lower cross beam 120, so that the lower cross beam 120 can move along the extending direction of the ground rail 110 after being erected on the upper end 112 of the ground rail 110.

Specifically, the upper end 112 of the ground rail 110 includes a first end 1121 and a second end 1122 disposed on both sides of the first end 1121. The second end 1122 is connected to the first end 1121 along the width direction of the upper end 112. After the ground rail 110 is engaged with the lower cross member 120, the first end portion 1121 abuts against the bottom wall 1231 of the groove 123, and the two second end portions 1122 abut against the two side walls 1232 of the groove 123, respectively. Thus, when the ground rail 110 penetrates into the lower cross member 120, the lower end surface 121 of the lower cross member 120 is at a lower level than the upper end surface 1123 of the ground rail 110, and the matching between the lower cross member 120 and the ground rail 110 is stable.

It can be understood that, in this embodiment, the depth of the groove 123 can be adjusted to adjust the length of the ground rail 110 penetrating into the lower cross beam 120, so that the lowest goods picking height of the bearing assembly arranged on the lower cross beam 120 can be adjusted, and the bearing assembly is further adapted to different occasions. Of course, in other embodiments, in order to further improve the utilization of the space at a lower height of the stereoscopic warehouse, a concave guide groove (not shown) may be formed on the ground, and the ground rail 110 is laid in the concave guide groove. Thereby, the distance between the lower cross member 120 and the ground can be further reduced.

Referring to fig. 2, fig. 2 is a partial structural schematic view of a traveling mechanism 200 according to the present application. In order to realize the movement of the lower beam 220 along the ground rail 210, the walking mechanism 200 in this embodiment further includes a first roller assembly 230, and the first roller assembly 230 is connected to the lower beam 220 and disposed on the ground rail 210 for driving the lower beam 220 to move along the extending direction of the ground rail 210. The first roller assembly 230 may include a first bracket 231, a driving member (not shown), a rotation shaft 234, and a traveling wheel 232, among others. The first bracket 231 can be connected with the lower beam 220 through the first mounting plate 233, the driving member is disposed on the first bracket 231, one end of the rotating shaft 234 is connected with the power output end of the driving member, the walking wheel 232 is rotatably sleeved on the other end of the rotating shaft 234, and the roller surface of the walking wheel 232 is located on the upper end surface of the ground rail 210 (see fig. 1). Therefore, the driving member can drive the rotating shaft 234 to rotate, so as to drive the traveling wheels 232 to rotate on the upper end surface of the ground rail 210, and further drive the lower beam 220 connected with the first roller assembly 230 to move.

Specifically, the first bracket 231 is provided with a mounting groove 2311 for allowing the traveling wheel 232 to rotate, and the rotating shaft 234 of the traveling wheel 232 is rotatably mounted in the mounting groove 2311; and one end of the rotation shaft 234 is connected to the walking wheels 232 and the other end is connected to the driving member for transmitting the driving power of the driving member to the walking wheels 232. Wherein the driving member may be a rotating electrical machine.

From this, after driving piece driven wheel 232 rotates, walking wheel 232 can take place to rotate on the up end of ground rail 210, and then drives the bottom end rail 220 who is connected with first roller assembly 230 and moves along the extending direction of ground rail 210 for locate the carrier assembly on bottom end rail 220 and can carry the article in a plurality of spatial regions of warehouse.

Of course, in other embodiments, the lower beam 220 may be driven in other ways. For example, the lower beam 220 is connected with a traction rope, and the traction rope moves along the ground rail 210 in a traction manner through a pulley. It is understood that, in order to drive the lower beam 220 to move along the ground rail 210, a person skilled in the art may select a suitable driving manner to drive the lower beam 220, and is not further limited herein.

Referring to fig. 3 in conjunction with fig. 2, fig. 3 is a schematic structural view of the walking assembly in fig. 2 in another direction. In order to improve the stability of the lower beam 220 when running on the ground rail 210 and prevent the lower beam 220 from being separated from the ground rail 210 when moving, in one embodiment, the walking mechanism 200 further includes a second roller assembly 240. The second roller assemblies 240 are provided in two sets, respectively abutting both sides of the second end portion 2122 of the upper end portion (see fig. 1) of the ground rail 210 from the width direction of the ground rail 210, so that the lower beam 220 can move along the extending direction of the ground rail 210.

Specifically, the second roller assembly 240 includes a second bracket 241, a connecting shaft 242, and a driven wheel 244. The second bracket 241 is arranged at the end of the first bracket 231 along the extending direction of the ground rail 210 through the second mounting plate 245; one end of the connecting shaft 242 is fixedly disposed on the second bracket 241, and the driven wheel 244 is sleeved on the other end of the connecting shaft 242; the side driven wheels 244 abut against both sides of the second end portions 2122, respectively, to limit the moving direction of the lower beam 220.

It will be appreciated that the second end portion 2122 needs to be partially exposed to the recess (see fig. 1) after the ground rail 210 is engaged with the lower cross member 220, so as to abut against the driven wheels 244 disposed on both sides of the second end portion 2122. That is, the length of the second end 2122 should be greater than the depth of the groove so that the driven wheel 244 can abut the second end 2122 exposed to the groove. Of course, in other embodiments, the driven wheel 244 may be offset from the lower cross member 220. For example, in fig. 2, the second roller assembly 240 may be directly disposed at the right end of the lower cross member 220, so that the second driven wheel 244 may be directly abutted against the ground rail 210.

In addition, the driven wheel 244 may be abutted against other positions of the ground rail 210, or separately disposed on a guide rail (not shown) matched with the extending direction of the ground rail 210, and the second roller assemblies 240 are respectively connected to the lower cross beam 220 and the guide rail, so as to guide the moving direction of the lower cross beam 220 on the ground rail 210. Those skilled in the art can adjust the setting position of the second roller assembly 240 according to practical situations.

Further, considering that the thickness of the ground rail 210 may vary during forging, if the distance between the roller surfaces of the two driven wheels 244 is strictly limited, the area where the thickness of the ground rail 210 varies may be jammed or loosened during the movement of the lower cross member 220 along the ground rail 210, or in order to adapt it to more ground rail models, or to avoid poor contact due to wear of the driven wheels during use.

Referring to fig. 4, fig. 4 is a schematic structural diagram of the second roller assembly 240 in the present application. In one embodiment, the connecting shaft 242 of the second roller assembly 240 is an eccentric shaft, so that the distance between the driven wheel 244 and the ground rail 210 can be adjusted by adjusting the offset angle of the eccentric shaft. Alternatively, the second roller assembly 240 may further include an eccentric member 243, and the eccentric member 243 is connected to the connecting shaft 242 and the driven wheel 244, respectively. The eccentric member 243 is disposed offset from the axis of the connecting shaft 242, and the driven wheel 244 is rotatably sleeved on the eccentric member 243.

Since the eccentric member 243 is offset from the axial center of the connecting shaft 242, the position of the eccentric member 243 can be adjusted by adjusting the fixed angle of the connecting shaft 242 on the second bracket 241, so that the distance between the two driven wheels 244 sleeved at one end of the eccentric member 243 can be adjusted. Thus, the running gear 200 in the present application can be adapted to ground rails 210 of different widths.

Further, to alleviate a rigid impact between the driven wheel 244 and the ground rail 210, in an embodiment, the roller surface of the driven wheel 244 may be further coated with an elastic buffer layer (not shown) for buffering the rigid impact between the driven wheel 244 and the second end 2122. The elastic buffer layer may be made of polyurethane or rubber. Of course, in other embodiments, other materials may be used, and those skilled in the art may make modifications according to the actual situation.

In addition, dust or other foreign materials may accumulate on the surface of the ground rail 210 after a long period of operation. In order not to affect the movement of the lower beam 220 on the surface of the ground rail 210, in an embodiment, the traveling mechanism 200 further includes a washing brush 250. Wherein, the washing brush 250 may be fixed on the second bracket 241 by a third mounting plate 251, for washing the foreign substances on the surface of the ground rail 210. Therefore, during the process that the lower beam 220 moves along the ground rail 210, the washing brush 250 arranged at the end of the lower beam 220 in the direction of the ground rail 210 can synchronously move along with the lower beam 220 to wash impurities on the surface of the ground rail 210, so as to avoid influencing the movement of the subsequent second roller and the lower beam 220.

Further, in order to improve the cleaning efficiency, the installation direction of the cleaning brush 250 may be installed at an angle with respect to the width direction of the floor rail 210 so that the cleaning brush 250 can simultaneously clean a large number of areas of the floor rail 210.

It is understood that a person skilled in the art can set the track path of the ground rail 210 according to actual requirements, and further adapt to different application occasions.
