DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-9As shown, the utility model is a heavy-duty friction accumulation roller suitable for battery pack assembly, which is used to transport battery packs. The tray carrying the battery pack runs on the roller. When encountering a separator or a stopper, the tray is forcibly blocked, and the rollers in the roller will stop rotating, reducing the friction between the roller and the friction surface of the tray, thereby increasing the service life of the conveying equipment. It includes a conveying unit 100 with rollers and a leg 200 for supporting the conveying unit 100. The bottom of the leg 200 is fixedly connected to the ground through a foot, and the top corresponding to the bottom of the leg 200 is connected to the conveying unit 100. The leg 200 plays a role in supporting the conveying unit 100 and keeping it away from the ground. The conveying unit 100 includes a support profile 110, the upper surface of the support profile 110 has a groove 111 for installing a roller assembly, and the lower surface opposite to the upper surface is fixedly connected to the top surface of the leg 200; the support profiles 110 are arranged in parallel in groups of two to form a support unit, and the two ends of the top surface of the leg 200 are respectively fixedly connected to the lower surface of the support profile 110 on the corresponding side; in order to ensure the conveying length, multiple groups of support units are overlapped in sequence along their length direction, preferably, three groups are overlapped. The opposite side surface of the support profile 110 is provided with a through hole for installing the roller assembly. The support unit is provided with a connecting shaft structure 300, and the two ends of the connecting shaft structure 300 respectively penetrate the side wall of the support profile 100 on the corresponding side and are respectively connected to the first roller structure 400 in the corresponding roller assembly; in order to ensure the smoothness of the conveying process, the connecting shaft structure 300 transmits the driving torque generated by the external drive device on one side from one side of the support profile 110 to the other side. The connecting shaft structure 300 includes a first flat shaft 310 and a first sleeve 320 connected to both ends of the first flat shaft 310, and the first sleeve 320 is connected to the first roller structure 400; the first roller structure 400 includes a second flat shaft 410, one end of the second flat shaft 410 is connected to the first sleeve 320, and the other end is connected to the first spiral bevel gear 440, a sliding roller 420 is sleeved on the middle part of the second flat shaft 410, and a first flange bearing 430 sleeved on the outer periphery of the second flat shaft 410 is symmetrically arranged with respect to the sliding roller 420; in order to further improve the wear resistance of the sliding roller 420, a wear-reducing ring 450 is arranged on its relative surface; in order to improve the shock absorption of the first roller structure 400, a retaining ring 460 is sleeved on the outer periphery of the second flat shaft 410, and the retaining ring 460 contacts the surface of the wear-reducing ring 450 and / or the first flange bearing 430.

[0029] The roller assembly also includes a second roller structure 500, which is multiple and equidistantly distributed along the length direction of the slot 111; the second roller structure 500 has a first drive shaft 510, one end of which is connected to a drive bevel gear 520, which faces the relatively outer side of the supporting profile 110, and a fixed roller 530 is mounted in the middle of the first drive shaft 510, and a second flange bearing 540 mounted on the first drive shaft 510 is symmetrically arranged about the fixed roller 530; the outer periphery of the first drive shaft 510 is also mounted with a retaining spring 460, which fits the surface of the second flange bearing 540. During the transportation of the battery pack, transportation is achieved by the rotation of the roller assembly.

[0030] In order to achieve the accumulation effect, an accumulation transmission shaft 600 is connected to the relative outer side surface of the support profile 110, and the accumulation transmission shaft 600 is equipped with accumulation units 620 distributed at equal intervals along its axial direction and a bearing seat 630 for fixed connection with the support profile 110. A second spiral bevel gear 610 is installed at one end of the accumulation rotating shaft 600, and a drive sprocket 640 is also sleeved on the outer periphery of the accumulation transmission shaft 600. The drive sprocket 640 is meshed with the transmission chain, and the power transmitted by the transmission chain enables the drive sprocket 640 to rotate on the outer surface of the accumulation transmission shaft 600.

[0031] Specifically, the accumulation unit 620 includes a second sleeve 621 for being mounted on the outer periphery of the accumulation transmission shaft 600, and a nut 625 and a bevel gear 624 are mounted on both ends of the second sleeve 621, and a spiral spring 622 is arranged between the two. The two ends of the spiral spring 622 are respectively connected to the corresponding nut 625 or bevel gear 624. The bevel gear 624 is meshed with the first spiral bevel gear 440 of the corresponding first roller structure 400 or the driving bevel gear 520 of the second roller structure 500 to achieve the transmission of motion and control the motion of the roller assembly. Friction plates 623 are arranged at both ends of the spiral spring 622, and the friction plates 623 are mounted on the outer periphery of the second sleeve 621.

[0032] The accumulation unit 620 presses the friction plate 623 against the end face of the bevel gear 624 through the pre-pressure generated by the coil spring 622, and adjusts the compression of the coil spring 622 through the fixing nut 625, thereby changing the friction torque between the friction plate 623 and the bevel gear 624. When the load torque is greater than the friction torque, the bevel gear 624 and the friction plate 623 slide relative to each other, and the accumulation function is realized at this time, reducing the friction between the roller assembly and the friction surface of the tray where the battery pack is placed, thereby increasing the service life of the conveying equipment.

[0033] In order to ensure the normal installation height of the roller, the system routing and support strength requirements, the support leg 200 here is a frame-type structure, and the frame adopts square tubes to ensure the overall support strength and line height. The top surface connected to the supporting profile 110 is provided with a profile connecting strip, and a wire trough is arranged on the side to install the sheet metal 210 to facilitate the integrated routing of the system.

[0034] In order to ensure the structural strength and stability between the supporting profiles 110 on both sides, connecting sheet metals are arranged equidistantly in the length direction of the supporting unit and are fixed to the supporting profiles 110 by fixing screws.

[0035] Working principle: After the legs 200 fix three sections of 2-meter-long supporting profiles 110 at a suitable height of 850mm from the ground, the top surfaces of each section of the profile are adjusted to the same height and leveled using the feet. The external drive structure is driven, and the drive sprocket 640 is meshed with the transmission chain. The power transmitted by the transmission chain is used to realize chain transmission, thereby transmitting the power to each accumulation unit 620. All the power is finally transmitted to the corresponding sliding roller 420 and fixed roller 530 through the roller combination connected to the accumulation unit. When the load is greater than the friction torque, the bevel gear 624 and the friction plate 623 slide relative to each other, thereby overcoming the rolling friction torque generated by the pallet and the heavy objects placed on the roller combination, thereby realizing a smooth heavy object accumulation and transmission process.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
