Description

Technical Field

[0001] The present application generally relates to the technical field of high-altitude transportation, and more specifically to an aerial suspension conveyor line and a control method. Background Art

[0002] Aerial suspension conveyor line, also known as suspension conveyor line or overhead conveyor, is a kind of equipment that continuously transports materials in space. Aerial suspension conveyor line is generally driven by a motor to make the traveling trolley, hanger and other components run on the overhead track to complete the transportation of materials. It has the technical advantages of high flexibility, small footprint, strong carrying capacity, easy maintenance and high safety.

[0003] Most of the existing overhead suspension conveyor lines are friction rod type, that is, the rotating friction rod is in friction contact with the wheel set of the trolley to drive the trolley to move. The friction rod type is mostly used in occasions where the weight of the goods is above 150kg. For goods weighing less than 150kg, the use of the friction rod type will cause a large waste of resources. Generally, the belt type, or the transmission belt type, is selected. The transmission belt type overhead suspension conveyor line has a low cost and is suitable for relatively light load occasions; however, due to the limitation of traction, the existing transmission belt type overhead suspension conveyor line cannot be used when it is arranged on a slope or when climbing the slope is required for transportation; additional customized lifting equipment is often required, because the space in the vertical direction of the slope is limited, and sometimes it is impossible to arrange additional lifting equipment. Even if the lifting equipment can be arranged, the customized lifting equipment is expensive, and there will be a series of problems in the connection between the lifting equipment and the overhead suspension conveyor line, which will affect the orderly and normal operation of the line.

[0004] Therefore, it is necessary to provide an aerial suspension conveyor line and a control method to at least partially solve the above problems. Summary of the invention

[0105] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application embodiments can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application embodiments, some technical features well known in the art are not described.

[0106] In order to fully understand the implementation of the present application, a detailed structure will be presented in the following description. Obviously, the implementation of the implementation of the present application is not limited to the specific details familiar to those skilled in the art.

[0107] The present application provides an aerial suspension conveyor line.

[0108] See also Figure 1 and Figure 2, the aerial suspension conveyor line 100 includes a first track 111, a second track 112, a traveling trolley 120 and a driving device 140. The first track 111 is arranged along the first horizontal direction D1. The second track 112 is connected to the first track 111, the second track 112 is inclined relative to the first horizontal direction D1 and the vertical direction DH, and the second track 112 is inclined upward relative to the first track 111. The bottom of the second track 112 is also connected to a switching member 115, and the switching member 115 is consistent with the extension direction of the second track 112. The traveling trolley 120 is configured to be able to move along the first track 111 and the second track 112. It should be noted that when the traveling trolley 120 travels to the second track 112, the traveling trolley 120 is partially in contact with the switching member 115. The driving device 140 is partially located inside the first track 111 and the second track 112, and the driving device 140 includes a transmission belt, which is configured in a closed shape. The driving device 140 is used to drive the traveling vehicle 120 to move along the first track 111 and the second track 112 .

[0109] According to the aerial suspension conveyor line 100 of the present application, a relatively light-loaded belt-type aerial suspension conveyor line can climb in an orderly manner, which greatly expands the applicable occasions of the aerial suspension conveyor line 100. In other words, for relatively light-loaded occasions, choosing a belt-type aerial suspension conveyor line can reduce the cost and waste of resources. Moreover, in the occasions where climbing is required, there is no need to set up additional lifting equipment for docking with the aerial suspension conveyor line 100, which reduces the construction difficulty and improves the stability of the line operation.

[0110] Furthermore, the traveling trolley 120 has a wheel set 122, and the first track 111 and the second track 112 both have a limiting groove 114 suitable for the wheel set, and the limiting groove 114 is used to limit the movement of the wheel set 122 along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction D1.

[0111] The aforementioned “upward tilt” and “limiting groove” are explained below.

[0112] The second track 112 is inclined upward relative to the first track 111. In other words, the second track 112 has a first end and a second end spaced apart along the first horizontal direction D1, and the top edge of the first end is located below the top edge of the second end. The first track 111 is connected to the first end, that is, when the traveling trolley 120 moves from the first track 111 to the second track 112, the second track 112 moves along the travel direction of the traveling trolley 120 (see Figure 2 The walking trolley 120 will experience the uphill slope formed by the second track 112.

[0113] As for the limiting grooves 114 at the first track 111 and the second track 112, those skilled in the art know that the first track 111 and the second track 112 have downward openings so that the trolley 120 extends downward relative to the first track 111 and the second track 112. Accordingly, the trolley 120 will not deviate relative to the track along a direction perpendicular to the extension direction of the track. For example, the first track 111 extends along the first horizontal direction D1, and accordingly, the trolley 120 cannot deviate relative to the first track 111 along the second horizontal direction. It can be understood that the second horizontal direction is perpendicular to the first horizontal direction D1.

[0114] Please continue reading Figure 1 and Figure 2 , the aerial suspension conveyor line 100 also includes a third track 113, the third track 113 is arranged along the first horizontal direction D1, and the third track 113 is connected to the end of the second track 112 away from the first track 111 along the first horizontal direction D1. In other words, the third track 113 is connected to the aforementioned second end. It can be understood that the third track 113 is located above the first track 111 and is spaced from the first track 111 along the first horizontal direction D1. The third track also has the aforementioned limiting groove 114. Preferably, the aforementioned first track 111, the second track 112 and the third track 113 can be constructed as an integrally formed aluminum profile to facilitate cutting and splicing.

[0115] See also Figures 2 to 4 , the wheel group 122 includes a first wheel group 123 and a second wheel group 124 suitable for the driving device 140. Specifically, when the traveling trolley 120 moves from the first track 111 to the second track 112, the first wheel group 123 is located in front of the second wheel group 124 along the travel direction of the traveling trolley 120. The first wheel group 123 and the second wheel group 124 both have a bracket 125 and a first linkage member 126. The first linkage member 126 is movably connected to the bracket 125 between a first position and a second position. It should be noted that the first linkage member 126 at the first position is connected to the driving device 140 to move with the driving device 140; the first linkage member 126 at the second position is disengaged from the driving device 140.

[0116] See also Figure 3, further, the bracket 125 includes a base plate 125a and a connecting rod 125b. The base plate 125a is used to install the wheel set 122, and the connecting rod 125b is connected to the base plate 125a and protrudes downward from the base plate 125a; and the connecting rod 125b is pivotally connected to the base plate 125a around its own axis direction. Specifically, the connecting rod 125b includes an upper connecting portion 125c and a lower connecting portion 125d. The upper connecting portion 125c is connected to the base plate 125a, and the lower connecting portion 125d is located below the upper connecting portion 125c and is movably connected to the upper connecting portion 125c. This is because, during the process of the walking trolley 120 going uphill or downhill, the wheel set 122 will experience a certain bump change, and the length of the connecting rod 125b can be fine-tuned autonomously (the lower connecting portion 125d is movably connected to the upper connecting portion 125c) to make the connection between the wheel set 122 and the driving device 140 smoother. It can be understood that the first linkage member 126 is located above the base plate 125a.

[0117] Those skilled in the art know that the traveling trolley 120 further includes a cross beam 121 , the wheel set 122 is located above the cross beam 121 and connected to the cross beam 121 , and a customized hanger 170 is provided below the cross beam 121 to carry goods.

[0118] First embodiment

[0119] See also Figure 2 , the first drive assembly 141 includes a first drive member 142, a first driven member 143 and a first transmission belt 144. Specifically, the first driven members 143 are arranged in pairs; those skilled in the art know that the first driven members 143 can be constructed as pulleys suitable for the first transmission belt 144 and corresponding pivot shafts. The first driven members 143 are arranged in pairs along the extension direction of the corresponding mounting rails. In this embodiment, the outer surface of the first transmission belt 144 is flat, and the first transmission belt 144 is wound around the first driven members 143 arranged in pairs. The first drive member 142 is transmission-connected to at least one first driven member 143 to drive the first transmission belt 144 to operate. For example Figure 2 In the embodiment, the first driving member 142 is configured as a motor and is connected to one of the first driven members 143 .

[0120] See also Figures 2 to 4 The first track 111 and the second track 112 are both connected to the first driving assembly 141. The walking trolley 120 also includes a second linkage member 130, which is at least connected to the bracket 125 at the first wheel group 123. The second linkage member 130 is located above the base plate 125a. Figure 3In the embodiment, the second linkage member 130 is constructed to have the same structure as the first linkage member 126, and the second linkage member 130 is connected to the bracket 125 at the first wheel group 123. In an embodiment not shown, the second linkage member 130 can be connected to the bracket 125 at the first wheel group 123 and the second wheel group 124. Further, the second linkage member 130 is movably connected to the bracket 125 between the third position and the fourth position. It should be noted that the second linkage member 130 located in the third position is connected to the first drive assembly 141, specifically, it abuts against the first transmission belt 144, so as to move with the first drive assembly 141; the second linkage member 130 located in the fourth position is disengaged from the first drive assembly 141 (specifically, the first transmission belt 144). Figure 3 In the embodiment, when the traveling trolley 120 is located at the first track 111, the first linkage member 126 is located at the first position, and the second linkage member 130 is located at the fourth position. Figure 4 In the embodiment, when the traveling trolley 120 is located at the second track 112, the first linkage member 126 is located at the first position, and the second linkage member 130 is located at the third position.

[0121] Specifically, the first wheel group 123 and the second wheel group 124 also include a first elastic member 127, a first lifting member 128 and a first abutting member 129. The first lifting member 128 is configured as a rod-shaped member and is movably connected to the base plate 125a along its own axis direction. The top of the first lifting member 128 is connected with a first linkage member 126 so that the first linkage member 126 can move between the first position and the second position relative to the bracket 125. The first elastic member 127 is sleeved to the outer periphery of the first lifting member 128 and is located between the first linkage member 126 and the base plate 125a.
