As shown in fig. 5, the rail guide roller 40 is a polyurethane concave wheel, and the rail 200 is provided with a boss 201 on a side surface, and the polyurethane concave wheel is slidably connected with the boss 201. Further, a boss 201 for sandwiching the rail is provided on the rail guide roller 40 with a rolling bearing (not shown).

As shown in fig. 1 and 2, the frame 51 is integrally formed with the pulley base 10, and a rack chute 52 along which a driving rack 53 slides is provided on the frame 51. The driving rack 53 includes a rack body 530, a sliding portion 532 located at one side of the rack body 530 and adapted to slide along the rack chute 52, and a gear engaging portion 534 located at the other side of the rack body 530 and engaged with the gear 57, and the lane change roller 55 is mounted on one end of the rack body 530. The latch 59 includes a rack end axially formed with the driven rack 58 and a mating end adapted for mating with an object (not shown) to be transported on the track 200. As shown in fig. 2, the pulley seat 10 is provided with a through hole 19, the latch 59 is disposed through the through hole 19, and a stopper 595 is disposed on a rack end of the latch 59 to prevent the latch 59 from falling off from the through hole 19 at the plugging position. Of course, it should be appreciated that the stop 595 does not interfere with the driven rack 58 at the rack end of the latch 59.

In addition, the two automatic plugging mechanisms 50 are respectively located at the outer sides of the two roller fixing plates 20, that is, the two roller fixing plates 20 are located at the inner sides of the saddle 10, and the two automatic plugging mechanisms 50 are respectively located at two sides, so that the object to be transported can be firmly plugged and combined by the automatic plugging mechanisms 50 to complete the transportation.

As shown in fig. 5 and 6, and referring to fig. 1 and 2, the rail car device 100 further includes a driving guide roller 60 mounted on one side 11 of the car seat 10, and the roller fixing plate 20 and the automatic insertion mechanism 50 are located on the other side 13 of the car seat 10, the driving guide roller 60 being adapted to be slidably coupled with a driving mechanism 300 for driving the rail car device 100 so that the rail car device 100 is driven along the rail 200. The drive guide roller 60 and the lane change roller 55 are polyurethane wheels which enhance the service life of these rollers.

In addition, as shown in fig. 5, in the present embodiment, the automatic plugging mechanism 50 further includes a linear bearing 597 mounted on the saddle 10, and the plug 59 is installed through the linear bearing 597 and is in clearance fit with the linear bearing 597, so that the plug can reciprocate up and down in the linear bearing 597.

The operation of the entire rail-trolley assembly 100 is described below in connection with fig. 1-6:

When the entire rail car assembly 100 is mounted in place on the rail 200, the rail guide rollers 40 thereon clamp the bosses 201 on the sides of the rail 200 (see fig. 5), and at the same time, the drive guide rollers 60 of the rail car assembly 100 are positioned in the slide grooves 311 on the fork 310 of the drive mechanism 300 (e.g., pulley gear) and can reciprocate linearly along the slide grooves 311 (see fig. 6). As shown in fig. 6, in combination with fig. 3, the rail 200 is an elliptical-like rail, with straight-line section rails 202 on both sides and arc-shaped section rails on both sides, including an inner arc-shaped section rail 203 and an outer arc-shaped section rail 207, so that when the rail pulley device 100 slides from the straight-line section rail 202 on one side to the arc-shaped section rail on one side, for example, to the outer arc-shaped section rail 207 on the other side, the rail pulley device 100 is still driven by the driving mechanism 300 and then enters the straight-line section rail 202 on the other side due to the sliding engagement of the driving guide roller 60 with the sliding groove 311 on the fork 310.

As is clear from fig. 3, roller channels are provided on the straight-line segment rail 202 on both sides of the rail 100, the roller channels include a release channel 204, a channel changing channel 205 and a plugging channel 206, a plugging channel 206 is provided on the outer end arc segment rail 207, and a release channel 204 is provided on the inner end arc segment rail 203. When the track pulley device 100 slides on the straight track 202, firstly, the lane change roller 55 of one automatic plugging mechanism 50 on the track pulley device 100 enters the lane change groove 205 from the release groove 204, as shown in fig. 3, under the limitation of the lane change groove 205, the limited lane change roller 55 drives the driving rack 53 to start sliding outwards (left side in fig. 3), so as to drive the gear 57 to rotate anticlockwise, and further drive the driven rack 58 on the plug pin 59 to extend outwards (vertically downwards in fig. 2), when the lane change roller 55 enters the plugging groove 206 from the lane change groove 205, the plug pin 59 on the upper side in fig. 4 enters the plugging position thereof, that is, enters the state of being plugged and matched with the objects (such as containers) to be transported with the jack, which are transported under the track 200. Next, as the track trolley assembly 100 continues to travel on the track 200, the lane-changing roller 55 of the other automatic plugging mechanism 50 also enters the lane-changing channel 205 from the release channel 204 and thus the plugging channel 206, such that the plug 59 thereon also enters the plugging position from the release position, which is shown in fig. 4 in the release position that has not yet entered the plugging position.

As shown in fig. 6 and referring to fig. 3, since the two side straight-line section rails 202 of the rail 200 are symmetrically provided with the release channel 204, the lane changing channel 205 and the roller channel of the insertion channel 206, when the rail pulley device 100 passes through the outer end arc-shaped section rail 207 and enters the other side straight-line section rail 202, the latch 59 of the automatic insertion mechanism 50 located in front is separated from the insertion position under the action of the lane changing channel 205 and enters the release position, and when the latch 59 of the other automatic insertion mechanism 50 also enters the release position, the rail pulley device 100 completes the transportation of the box cargo box. It will be appreciated that as the lane-change roller 55 passes from the outer arcuate section track 207 into the other linear section track 202 and from the mating channel 206 through the lane-change channel 205 into the release channel 204, the drive rack 53 slides inwardly of the track 200 as the lane-change roller 55, thereby driving the gear 57 clockwise and, in turn, the driven rack 58 on the latch 59 to retract vertically inwardly (vertically upwardly in fig. 2) such that the latch 59 eventually passes into the release position (see the lower latch 59 position in fig. 4).

It should be noted that, when the track pulley device 100 travels along the two arc-shaped sections of the track 200, since the tension springs 30 are connected to the outer ends of the two roller fixing plates 20, the center distance between the pair of track guide rollers 40 on each roller fixing plate 20 along the section of the track profile can be adjusted by the tension springs 30, so that the tight fit between the track guide rollers 40 and the track 200 is always maintained, and the clamping force to the track 200 is maintained. In addition, the two roller fixing plates 20, that is, the two rows of rail guide rollers 40 are provided, so that the rail pulley device 100 can effectively travel along the rail 200, and derailment and other phenomena can be avoided. In addition, the two automatic plugging mechanisms 50 are provided in the present embodiment so as to ensure a more stable plugging engagement with the container of the box body. It will be appreciated that it is also possible to provide only one roller securing plate plus two rail guide rollers thereon, while ensuring that the transfer box cargo box can be docked, although the automatic docking mechanism 50 could be provided with only one.

While the technical content and features of the present invention have been disclosed above, it will be understood that various changes and modifications to the above-described structure, including combinations of technical features individually disclosed or claimed herein, and other combinations of these features as apparent to those skilled in the art may be made under the inventive concept of the present invention. Such variations and/or combinations fall within the technical field to which the invention relates and fall within the scope of the claims of the invention.
