It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Fig. 1-7 illustrate an exemplary configuration 100 of a continuous cycle elevator provided by an embodiment of the present application.

As shown in fig. 1-4, the present application provides a continuous circulation elevator, in which two closed-loop rails 102 that are staggered up and down and are parallel are relatively disposed on a fixed frame 101 of the continuous circulation elevator, and a transmission chain 103 and a trolley line 104 are disposed along the closed-loop rails 102; a plurality of conveying devices 105 are movably connected between the two transmission chains 103, and the plurality of conveying devices 105 are respectively connected with a hub 108 on a sliding contact line 107 through an electric slip ring 106; the transmission chain 103 is movably connected with a power device 110 arranged on the fixed frame 101 through a transmission device 109.

In this embodiment, the closed-loop track 102 may be a closed-loop track of any shape, and by way of example, the closed-loop track 102 may be a circular or elliptical closed-loop track. In some alternative implementations, the closed-loop track 102 is oblong. The two ends of the long circular track are semicircular tracks, and the semicircular tracks at the two ends are formed by connecting two parallel straight tracks. In the cyclic lifting process of the conveying device along the long circular track, the straight track in the long circular track facilitates the control of the lifting height of the conveying device, and the semicircular track provides the smoothness of the conveying device in the cyclic rotation process.

The two closed-loop tracks 102 have a height difference in the vertical direction, and the height difference can be specifically set according to the size of the conveying device and the transported object, and is not limited herein. Because the two closed-loop tracks 102 are vertically staggered and parallel, the two transmission chains 103 arranged on the closed-loop tracks 102 are vertically staggered and parallel. A height difference exists between both ends of each of the plurality of conveyors 105 and both connections of the two drive chains 103, which is the same as a height difference of the two closed-loop tracks 102 in the vertical direction.

As an example, the conveyor 105 running to the top end of the closed-loop track 102 has one end connected to the top end of one of the two drive chains 103 and the other end connected to the top end of the other of the two drive chains 103.

Because the two ends of the conveying device 105 are movably connected to the two transmission chains 103, and the two transmission chains 103 are vertically staggered and parallel, the conveying devices 105 can be kept horizontal in the rotating process of the transmission chains 103 along the closed-loop track 102, conveyed transported objects can be stably conveyed, and the stability and the safety of the continuous circulating elevator are improved.

In this embodiment, the two ends of the conveying device 105 are also connected to the trolley lines 107 through the electrical slip rings 106, and the electric energy and the signals are conveyed during the cyclic lifting process of the conveying device 105. As an example, the trolley line 105 and the power device 110 may be connected to a control device having a signal processing function, and receive a control signal from the control device to start and stop the power device 110 and the conveying device 105.

The conveyor 105 may be any conveyor that performs the task of transporting the cargo. As an example, the conveying device may be a roller conveyor.

In some alternative implementations, the conveyor 105 is a belt conveyor. The belt conveyor can convey the transported objects smoothly in the transporting process of the transported objects.

In this embodiment, the power device 110 is a device capable of providing power for the rotation of the transmission chain 103, and includes, but is not limited to, an electric motor, a heat engine, and the like. Parameters such as power and rotation speed provided by the power device 110 may be specifically set according to the actual logistics transportation situation, and are not limited herein.

As shown in fig. 5-6, in some alternative implementations of the present embodiment, the transmission 109 includes: a first chain wheel 1091, a second chain wheel 1092, a third chain wheel 1093, a fourth chain wheel 1094, a fifth chain wheel 1095, a linkage shaft 1096, a first chain 1097 and a second chain 1098;

the driving chain wheel of the power device 109 is connected with a first chain wheel 1091 arranged on a linkage shaft 1096 through a first chain 1097, a second chain wheel 1092 and a third chain wheel 1093 are coaxially arranged on the linkage shaft 1096 and the first chain wheel 1091, the second chain wheel 1092 is meshed with one of the two transmission chains 103, the third chain wheel 1093 is connected with a fourth chain wheel 1094 through a second chain 1098, the fourth chain wheel 1094 is coaxially connected with a fifth chain wheel 1095, and the fifth chain wheel 1095 is meshed with the other of the two transmission chains 103.

In this implementation, the first chain wheel 1091, the second chain wheel 1092 and the third chain wheel 1093 rotate coaxially, and because there is a height difference in the vertical direction between the two driving chains 103, further driving needs to be performed by the second chain 1098, so that the two driving chains 103 rotate simultaneously.

In this implementation, the first sprocket 1091, the third sprocket 1093, and the fourth sprocket 1094 are the same in size, all being the first size; the second sprocket 1092 and the fifth sprocket 1095 have the same size, and are both the second size; the first dimension is less than the second dimension. Specifically, the first size and the second size may be specifically set according to actual logistics transportation conditions, and are not limited herein

As shown in fig. 7, in some optional implementations of the present embodiment, the transmission chain 103 includes a plurality of limiting wheel sets 1031, and the limiting wheel sets 1031 include two limiting wheels with rotation axes perpendicular to each other. A plurality of limiting wheel sets are sequentially connected to form a closed-loop transmission chain. The closed-loop track 102 is provided with a closed-loop opening, the cross section of the closed-loop track 102 is C-shaped, and the two transmission chains 103 are sequentially arranged in the two closed-loop tracks 102. The limiting wheel set is used for driving in a chain imitating mode, the assembly precision of the continuous circulation elevator is reduced, and meanwhile the stable operation of the car body is guaranteed.

In some alternative implementations of this embodiment, a plurality of bearing sets 111 are provided vertically along the drive chain 103; each bearing group 111 comprises two bearings which are sequentially arranged on the two transmission chains 103, each bearing penetrates through an annular opening on the annular track 102 and extends to the outer side of the closed-loop track 102, and the two bearings in the same bearing group are in the same position in the transmission chain to which the two bearings belong.

As an example, 10 bearings are provided on each of two identical drive chains 103. The 10 bearings are evenly arranged along the drive chain 103. The height difference between the two bearings in each set of bearings is the same as the height difference between the two closed-loop tracks 102.

In some alternative implementations of the present embodiment, two ends of the same conveyor 105 are connected to two bearings in the same bearing set through vertical links, respectively.

In some alternative implementations of this embodiment, adjacent bearings on the same drive chain 103 are movably connected by a bearing connecting rod 112. In this embodiment, the whole lifting motion of the continuous cycle elevator drives the second chain wheel 1092 and the fifth chain wheel 1095 by the power device 110 through chain transmission, and the second chain wheel 1092 and the fifth chain wheel 1095 cooperate with the bearing at the outer side of the transmission chain 103 formed by the limiting wheel set 1031 to realize the lifting of the conveying device. Because the bearing is in the track outside, belong to the cantilever in physical structure, if second sprocket 1092, the direct application of force of fifth sprocket 1095 is on single bearing, single spacing wheelset atress in the drive chain 103 that spacing wheelset 1031 constitutes can be very big, cause dislocation scheduling problem easily, bearing connecting rod 112 has been added in the bearing outside consequently, let the bearing in the closed loop track 102 outside also form chain connection, so, assume that a bearing receives the promotion pulling force, a plurality of bearings after the chain connection all can bear this lifting force jointly, make the drive chain atress that spacing wheelset constitutes even, the life of continuous cycle lifting machine has been improved.
