Description

Technical Field

[0001] This 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] An aerial suspension conveyor line, also known as a suspended conveyor line or an overhead conveyor, is a device for continuously transporting materials in space. An aerial suspension conveyor line is generally driven by a motor to make components such as traveling trolleys and hangers run on an overhead track, thereby completing the transportation of materials. It has technical advantages such as high flexibility, small floor area, strong load-bearing capacity, easy maintenance, and high safety.

[0003] Existing aerial suspension conveyor lines are mostly of the friction rod type, that is, a form in which a rotating friction rod is in frictional contact with the wheel set of the traveling trolley to drive the traveling trolley to move. The friction rod type is mostly used in occasions where the cargo weight is above 150 kg. For goods with a weight below 150 kg, using the friction rod type causes relatively large resource waste, and generally, a belt type, or rather a conveyor belt type, is selected. The conveyor belt type of aerial suspension conveyor line has a low construction cost and is suitable for relatively light-load occasions; however, due to traction limitations, existing conveyor belt type aerial suspension conveyor lines cannot be used when arranging on a sloping site or when climbing and conveying; often, additional customized lifting equipment is required. Because the space in the vertical direction of the slope is limited, sometimes it is impossible to additionally arrange lifting equipment. Even if lifting equipment can be arranged, the customized lifting equipment has a high cost, and there will be a series of problems in the docking of the lifting equipment and the aerial suspension conveyor line, affecting the orderly and normal operation of the line body.

[0004] Therefore, there is a need 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 given to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without one or more of these details. In other examples, in order to avoid confusion with the embodiments of the present application, some well-known technical features in the art are not described.

[0106] In order to thoroughly understand the embodiments of the present application, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art.

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

[0108] Please refer to Figure 1 and Figure 2, the overhead 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 a first horizontal direction D1. The second track 112 is connected to the first track 111. The second track 112 is inclined with respect to the first horizontal direction D1 and the vertical direction DH, and the second track 112 is inclined upward with respect to the first track 111. A switching member 115 is further connected to the bottom of the second track 112, and the switching member 115 is consistent with the extending 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 in partial contact with the switching member 115. The driving device 140 is partially located inside the first track 111 and the second track 112. The driving device 140 includes a transmission belt, and the transmission belt is configured in a closed shape. The driving device 140 is used to drive the traveling trolley 120 to move along the first track 111 and the second track 112.

[0109] According to the overhead suspension conveyor line 100 of the present application, a relatively lightly loaded belt-type overhead suspension conveyor line can climb slopes orderly, greatly expanding the applicable occasions of the overhead suspension conveyor line 100. In other words, for relatively lightly loaded application occasions, selecting a belt-type overhead suspension conveyor line can reduce the construction cost and reduce resource waste. And, in occasions where climbing is required, there is no need to additionally set up lifting equipment for docking with the overhead suspension conveyor line 100, reducing the construction difficulty and at the same time improving the stability of the line operation.

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

[0111] The following explanations are given for the aforementioned "upward inclination" and "limiting groove".

[0112] The second track 112 is inclined upward with respect to the first track 111. In other words, the second track 112 has a first end and a second end spaced 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 to say, when the traveling trolley 120 moves from the first track 111 towards the second track 112, along the traveling direction of the traveling trolley 120 (see Figure 2 the arrow indication in), the traveling trolley 120 will experience an uphill formed by the second track 112.

[0113] Regarding 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 walking trolley 120 extends downward relative to the first track 111 and the second track 112. Correspondingly, in the direction perpendicular to the track extension direction, the walking trolley 120 will not deviate from the track. For example, the first track 111 extends along the first horizontal direction D1. Correspondingly, the walking trolley 120 cannot deviate from 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 to refer to Figure 1 and Figure 2 , the overhead suspension conveyor line 100 further includes a third track 113. The third track 113 is arranged along the first horizontal direction D1. The third track 113 is connected to one end of the second track 112 far 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, second track 112 and third track 113 can be constructed as integrally formed aluminum profiles for easy cutting and splicing.

[0115] Please refer to Figures 2 to 4 , the wheel set 122 includes a first wheel set 123 and a second wheel set 124 adapted to the driving device 140. Specifically, when the walking trolley 120 moves from the first track 111 towards the second track 112, along the traveling direction of the walking trolley 120, the first wheel set 123 is located in front of the second wheel set 124. Both the first wheel set 123 and the second wheel set 124 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 located at the first position is connected to the driving device 140 to move following the driving device 140; the first linkage member 126 located at the second position is disengaged from the driving device 140.

[0116] Please refer to Figure 3, Further, the bracket 125 includes a base plate 125a and a connecting rod 125b. The base plate 125a is used for mounting the wheel set 122, and the connecting rod 125b is connected to the base plate 125a and protrudes downward from the base plate 125a; moreover, the connecting rod 125b is pivotally connected to the base plate 125a about 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 uphill or downhill process of the walking trolley 120, the wheel set 122 will experience certain bumpy changes, and the length of the connecting rod 125b can be adjusted autonomously (the lower connecting portion 125d is movably connected to the upper connecting portion 125c) so that the connection between the wheel set 122 and the driving device 140 is 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 walking trolley 120 further includes a cross beam 121. The wheel set 122 is located above the cross beam 121 and is connected to the cross beam 121, and a customized hanger 170 is provided below the cross beam 121 to carry goods.

[0118] The first embodiment

[0119] Please refer to Figure 2 , The first driving assembly 141 includes a first driving 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 configured as pulleys suitable for the first transmission belt 144 and corresponding pivot shafts. The first driven members 143 are arranged in pairs along the extending direction of the corresponding mounting track. 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 driving member 142 is drivingly connected to at least one first driven member 143 to drive the first transmission belt 144 to operate. For example Figure 2 in, the first driving member 142 is configured as a motor and is connected to one of the first driven members 143.

[0120] Please refer to Figures 2 to 4 , The first track 111 and the second track 112 are both connected with the first driving assembly 141. The walking trolley 120 further includes a second linkage member 130, and the second linkage member 130 is at least connected to the bracket 125 at the first wheel set 123. The second linkage member 130 is located above the base plate 125a. For example Figure 3In this case, the second linkage member 130 is configured 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 set 123. In an embodiment not shown, the second linkage member 130 may be connected to the brackets 125 at the first wheel set 123 and the second wheel set 124. Further, the second linkage member 130 is movably connected to the bracket 125 between a third position and a fourth position. It should be noted that the second linkage member 130 in the third position is connected to the first drive assembly 141, specifically, it abuts against the first transmission belt 144 to move along with the first drive assembly 141; the second linkage member 130 in the fourth position is disengaged from the first drive assembly 141 (specifically, the first transmission belt 144). Figure 3 In this case, when the walking trolley 120 is located at the first track 111, the first linkage member 126 is in the first position and the second linkage member 130 is in the fourth position. Figure 4 In this case, when the walking trolley 120 is located at the second track 112, the first linkage member 126 is in the first position and the second linkage member 130 is in the third position.

[0121] Specifically, both the first wheel set 123 and the second wheel set 124 further 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 substrate 125a along its own axis direction. The top of the first lifting member 128 is connected to the first linkage member 126 so that the first linkage member 126 is movable relative to the bracket 125 between a first position and a second position. The first elastic member 127 is sleeved on the outer periphery of the first lifting member 128 and is located between the first linkage member 126 and the substrate 125a. It can be understood that the first elastic member 127 is used to return the first linkage member 126 from the second position to the first position, or rather, the first elastic member 127 is used to keep the first linkage member 126 in the first position. The first abutting member 129 is configured as a roller and is pivotally connected to the first lifting member 128 about its own axis direction, and the first abutting member 129 is located below the substrate 125a.
