In the implementation process, two moving rails capable of receiving the rollers are provided for supporting the movement of the bearing frame 210, and since only the contact surface for the rollers to roll needs to be provided, the two rails have simple structures. The movement of the bearing frame 210 is dragged by a synchronous belt 400, the bearing frame 210 is provided with a suspension beam for suspending the bearing box 230, and the bearing box 230 adopts a suspension mode, so that the following advantages are achieved: the track 100 can be attached to the lower part of the pavement, so that the construction difficulty is reduced, and the space requirement on a building is reduced; the transport item can be retrieved quickly in case of equipment failure.

Fig. 6 is a partial block diagram of a carrier 210 according to an embodiment of the present application. Referring to fig. 6, the bottom of the carrier 210 is provided with a plurality of sets of suspension beams that can suspend carrier boxes 230 of different sizes. The bottom of the carrier 210 is provided with a first suspension beam 211, a second suspension beam 212 and a third suspension beam 213. The first suspension beam 211, the second suspension beam 212 and the third suspension beam 213 are sequentially arranged from high to low in the height direction, and the suspension widths configured by the first suspension beam 211, the second suspension beam 212 and the third suspension beam 213 are sequentially widened to adapt to the suspension sizes of different load-bearing boxes 230.

In another implementation, the carrier case 230 may also be mounted on an upper portion of the carrier 210. The position relationship and the connection relationship between the bearing box 230 and the bearing frame 210 are not specifically limited in the present application, and any bearing structure that can fix the bearing box 230 and drive the bearing box 230 to move on the rail 100 falls into the protection scope of the present application.

It should be noted that, when the carrier box 230 is mounted on the upper portion of the carrier 210, the track 100 may be configured as the first track 110 and the second track 120, or may be a continuous track having a predetermined width. The structure of the rail 100 is not particularly limited, and any rail structure that can provide a contact surface for the roller to roll falls within the scope of the present application.

The roller mechanism may be directly disposed on the transported object, and the roller mechanism may be capable of moving on the structural form of the first rail 110 and the second rail 120 or the continuous rail.

Fig. 7 is a schematic structural diagram of a track according to an embodiment of the present application. Referring to fig. 7, the first rail 110 and the second rail 120 each include a horizontal rail and a vertical rail. The horizontal rails of the first rail 110 and the second rail 120 have the same height and are spaced apart from each other by a predetermined distance, and the vertical rails of the first rail 110 and the second rail 120 are parallel and opposite to each other. The support wheels 214 on the carriage 210 or rollers on the transported object (in fig. 7, the rollers on the transported object are taken as an example) roll on the horizontal rails of the first rail 110 and the horizontal rails of the second rail 120.

The second horizontal guide wheel set 222 includes two horizontal guide wheels having an axis perpendicular to the axis of the support wheel and capable of rolling on the vertical rail of the second rail 120.

In the implementation process, the vertical rails of the first rail 110 and the second rail 120 can define rails having a predetermined width, so that the carriage 210 always moves within the defined rails without being separated from the rails. The arrangement of the supporting wheel or the roller mechanism can enable the conveyed object to smoothly advance on the first track 110 and the second track 120, the arrangement of the horizontal guide mechanism 220 can reduce the friction force between the conveyed object and the first track 110 and the second track 120 because the horizontal guide wheels on the two sides roll on the vertical tracks on the two sides in the advancing process of the conveyed object, and the conveyed object can be always limited between the first track 110 and the second track 120 without deviating from the movement track of the conveyed object because the horizontal guide wheels on the two sides are always in contact with the vertical tracks on the two sides.

In a further possible implementation, the second horizontal guiding wheel set 222 further comprises an elastic adjustment device. In order to provide a very advantageous implementation for the automated control of the entry and removal of articles into and out of the horizontal transport system, the carriers should have a good repeatability accuracy after stopping. When the timing belt 400 is located at one side of the first horizontal guide wheel set 221, the carrier 210 tends to move to the side close to the timing belt 400, and the first horizontal guide wheel tends to closely contact the vertical track surface of the first track 110, which is advantageous to improve the repeatability of the position coordinates of the carrier after stopping. And the elastic adjusting device is arranged on the second horizontal guiding wheel set 222, the elastic force always presses the bearing frame 210 to move to one side of the synchronous belt 400, the trend that the vertical rail surface of the first horizontal guiding wheel and the vertical rail surface of the first rail 110 are tightly attached is enhanced, and the repeated precision of the position coordinate of the bearing frame after the bearing frame stops is improved.

The third link 540 pushes the transported object to move on the track while the third link 540 moves along with the belt 400.

Fig. 14 is a schematic structural diagram illustrating yet another traction mechanism according to an embodiment of the present application. Referring to fig. 14, the traction mechanism 500 also includes a torque balance track 550 and a torque balancer 560.

The moment balance rail 550 is installed between the timing belt 400 and the transported object to provide a defined trajectory parallel to the transport trajectory of the transported object. In one possible embodiment, the moment balancing rail 550 is configured with a first guide 551 and a second guide 552 that are spaced apart and arranged in parallel. The first guide rail 551 and the second guide rail 552 are disposed at the same height and are parallel to the track. The third connecting rod 540 passes through a gap between the first guide 551 and the second guide 552.

The moment balancer 560 is installed on the third connecting rod 540 and can move on the moment balancing rail 550 along with the third connecting rod 540, for balancing the moment that the third connecting rod 540 receives in pushing the transported object 200.

When the load of the transported object is gradually increased, the stress concentration phenomenon may cause the local stress to firstly break through the allowable value, causing the early damage of the synchronous belt 400. In the implementation process, the moment balance rail 550 and the moment balancer 560 are arranged to share a part of the bending moment of the third connecting rod 540, so that the stress concentration phenomenon applied to the connecting position of the synchronous belt 400 is greatly reduced, and the service life of the synchronous belt 400 is prolonged.

Fig. 15 is a schematic structural diagram of a torque balancer according to an embodiment of the present application. See fig. 15. The torque balancer 560 includes a guide pulley 561, a first carrier wheel group 562, and a second carrier wheel group 563.

The guide pulley 561 is rotatably connected to a portion of the third connecting rod 540 between the first guide 551 and the second guide 552, and the guide pulley 561 falls into a sliding groove formed by the side of the first guide 551 and the side of the second guide 552.

The second bearing wheel set 563 comprises a second force arm support connected to the third connecting rod 540 and located below the moment balance rail 550, the second force arm support is perpendicular to the axis of the third connecting rod 540, and a roller attached to the lower surface of the moment balance rail 550 and capable of rolling on the moment balance rail 550 is installed at an end of the second force arm support away from the third connecting rod 540. In a preferred embodiment, the first force arm and the second force arm are equal in length along the length of the moment balance track 550.

The above-described embodiment is applicable to the manner in which the third connecting rods 540 are connected to the loading ledges 210 on the conveyed object. In the above implementation process, the torque balancer 560 of the above structure can reduce stress concentration and maintain turning performance of the timing belt 400. The rollers in the torque balancer 560 limit the deflection of the third connecting rod 540, so as to provide a deflection torque against the load P, and the third connecting rod 540 changes from bearing torque to bearing simple thrust, thereby greatly weakening the stress concentration phenomenon and prolonging the service life of the synchronous belt 400.

In yet another possible embodiment, the timing belt may also be arranged below and above the carriage 210. When the hold-in range is located the lower top that bears the frame, the structure of drive mechanism can refer to the hold-in range and be located the structure when bearing the frame directly over, only its structure and hold-in range lie bear the structure directly over about orbital horizontal central plane symmetry can.
