Fig. 1 schematically illustrates a track assembly according to the present invention. As shown in fig. 1, the rail assembly comprises two rails 10 arranged in parallel and at least one rail cross connecting device 20, wherein the rail cross connecting device 20 comprises a cross beam 21 and two side connecting plates 22.

As can be seen from the cross section of the rails 10 in fig. 1, the two rails 10 have an upper side 12 and an inner side 11 opposite each other. Wherein, go up side 12 and can place the freight transport vehicle with, bear the weight of freight transport vehicle, medial surface 11 relative each other can cooperate stop device to use for the freight transport vehicle removes according to the direction that track 10 extends. In practice, the track 10 is typically a straight track of a certain length, for example a monorail of 2.8 metres length, but may of course be a track of other length, which can be installed to connect the monorail together longitudinally as required.

The rail cross connecting device 20 comprises a cross beam 21 and two side connecting plates 22. As shown in fig. 1, two side connection plates 22 are fixed to both ends of the cross member 21, respectively, and are perpendicular to the cross member 21. In actual production, the side connecting plates 22 and the cross beam 21 are fixed by welding. For the single track transverse connecting device 20, the welding amount is small, the welding deformation is easy to control, and the subsequent adjustment or replacement is easy, so that the machining precision requirement is well met.

As shown in fig. 1, the two side connection plates 22 have first connection holes 221, and second connection holes (hidden by the side connection plates 22, not shown) corresponding to the first connection holes 221 are formed in the inner side surfaces 11 of the two rails, and the two side connection plates 22 are closely fixed to the inner side surfaces 11 of the two rails by using connection members (not shown) to pass through the first connection holes 221 and the second connection holes.

The side connection plates 22 and the rails 10 can be manufactured in batches as standard parts, and the positions of the first connection holes 221 of the side connection plates 22 and the second connection holes on the inner side surfaces 11 are predetermined, so that the rail transverse connection device 20 can enable the upper side surfaces 12 of the two rails to be on the same plane after being tightly fixed with the inner side surfaces 11 of the two rails. Alternatively, in order to prevent the upper sides 12 of the two rails from being not on the same plane due to machining errors, the relative heights of the two rails 10 can be adjusted to be on the same plane by adjusting the relative heights of the two rails 10, for example, the second connection holes on the inner sides 11 of the two rails or the first connection holes 221 of the side connection plates 22 are vertically elongated connection holes.

After the single track cross connecting device 20 is machined, the two side connecting plates 22 are respectively fixed to the inner side surfaces 11 of the two tracks by means of connecting members (not shown) passing through the second connecting holes on the inner side surfaces 11 and the corresponding first connecting holes 221 on the side connecting plates 22, so that the track cross connecting device 20 is connected to the two tracks 10 in a non-welding manner. Since this way of fixing does not present problems of deformation due to a large number of welds, it is easy to achieve precision of the distance of the upper sides 12 of the two rails on one plane and the inner sides 11 of the two rails.

In one embodiment of the present invention, the connecting member passing through the second connecting hole on the inner side surface 11 of the rail and the corresponding first connecting hole 221 on the side connecting plate 22 is a bolt. Since the bolt is screwed to connect and fix the two components, it is easy to install and disassemble, so that the installation, maintenance and replacement of the components of the rail assembly are easier to implement.

Fig. 2 schematically illustrates a side connection plate according to an embodiment of the present invention. As shown in fig. 2, the first connection hole 221 of the side connection plate 22 is a vertically elongated hole. The vertical slots, in combination with the connectors, allow the relative height of the upper sides 12 of the two rails to be adjusted during installation or use, so that the upper sides 12 of the two rails are in the same plane.

Fig. 3 schematically illustrates a right angle reinforcement in an embodiment according to the present invention. As shown in fig. 3, the right-angle reinforcing member 30 includes a first flat plate side 31 and a second flat plate side 32 that are perpendicular to each other. The first plate side 31 is fixed in a close contact with the side connection plate 22, and the second plate side 32 is fixed in a close contact with the cross beam 21. The rail cross connecting device 20 is used to fix two rails 10, wherein it is important that the connection of the cross beam 21 and the side connection plate 22 is firm and precise perpendicular to each other. Through right angle reinforcement 30 to the side connection board 22 and the close contact of crossbeam 21 fixed, can be so that the connection of the two is more firm, simultaneously, through the right angle limiting displacement of right angle reinforcement 30, guarantee that side connection board 22 and crossbeam 21 reduce in the use and warp, keep the vertical state.

Fig. 4 schematically illustrates a cargo conveying system according to the invention. In one embodiment of the invention, as shown in fig. 4, the cargo conveying system includes a track assembly as described in any of the above embodiments, and a cargo transporter 40. The freight transporter 40 includes a movement assembly 41, the movement assembly 41 enabling the freight transporter 40 to move along the track 10.

As shown in fig. 4, the upper side of the cargo-transporting vehicle 40 is a plane structure, and can be used for placing cargo. In order to make the placement of the goods more stable, optionally, the upward facing side of the goods transport vehicle 40 has a detent device, so that the goods can be placed on the goods transport vehicle 40 stably; a tray for placing goods can also be fixed on the upward side of the goods transport vehicle 40; of course, other blocking structures are also possible, not to mention one by one.

The moving assembly 41 typically includes rotatable road wheels, and the freight car 40 can move as the road wheels roll on the upper side 12 of the two rails. As shown in fig. 4, in one embodiment of the present invention, the moving assembly 41 includes two traveling wheel sets 411, and the traveling wheel sets 411 are disposed on the upper sides 12 of the two rails, and support the cargo transporter 40 and enable it to move on the rails 10.

Alternatively, the moving assembly 41 may be provided with a driving device for driving the moving device 41 to move the cargo transporter 40 along the rail 10; an external drive device may also be used to move the freight car 40.

In one embodiment of the present invention, the moving assembly 41 further comprises a limiting device, under the action of which the cargo transporter 40 can be ensured to move along the rail 10. Alternatively, the limiting means may be combined with the road wheel set 411, for example, by having a rim with a larger diameter than the road wheel set 411 on the side of the road wheel set 411 facing the inside of the rail 10, which rim may function as the limiting means. The distance between the rims of the opposite road wheel sets 411 on the two rails 10 towards the side faces of the rails where the wheels are located is slightly smaller than the distance between the inner side faces 11 of the two rails, so that the rims of the road wheel sets 411 can play a limiting role, and the freight car 40 can move along the rails 10.

As shown in fig. 4, in an embodiment of the present invention, the limiting device includes two limiting wheel sets 412, and the limiting wheel sets 412 can move along the inner side surfaces 11 of the two rails respectively. Optionally, the distance between the tangent lines of the outer rims of the limiting wheels opposite to each other on the two sides of the cargo transporter 40 in the limiting wheel set 412 may be slightly smaller than the distance between the inner sides 11 of the two rails, so that the cargo transporter 40 can move smoothly while the limiting wheel set 412 can play a limiting role. Further optionally, the limiting wheel set 412 may be connected to the cargo transporter 40 through an elastic connection member, so that the limiting wheel set 412 may adjust the distance between the outer rim tangents of the limiting wheels opposite to the two sides of the cargo transporter 40 with a small amplitude, and when the limiting effect is achieved, the cargo transporter 40 may move smoothly.

As shown in fig. 4, since the spacing wheel set 412 needs to move on the inner side surfaces 11 of the two rails, in general, the spacing wheel set 412 moves on the upper portion of the inner side surface 11, and the side connecting plates 22 of the rail assembly are fixed on the lower portion of the inner side surface 11 through connecting members, so as to avoid position collision with the spacing wheel set 412. Alternatively, the cross member 21 is also fixed to the side link plate 22 at a lower position. This allows more space above the cross member 21 to be reserved for the cargo transporter 40 or for other equipment such as a drive mechanism for driving the cargo transporter 40.
