Description

Technical Field

[0001] The utility model generally relates to the technical field of high-altitude transportation, and more specifically relates to an aerial suspension conveyor line. Background Art

[0002] An overhead conveyor line, also known as a suspended conveyor line or overhead conveyor, is a device that continuously transports materials in space. It offers technical advantages such as high flexibility, a small footprint, strong load-bearing capacity, ease of maintenance, and high safety. A belt-type overhead conveyor line, as a type of overhead conveyor line, combines the features of belt conveying and overhead suspension, achieving continuous and efficient material transport in space. In existing overhead conveyor lines, as the wheels move along the track, they often deviate horizontally relative to the track, affecting conveying accuracy and increasing wear on the equipment. Furthermore, in actual use, the trolleys used to carry goods often need to stop or accumulate. Existing accumulation systems are prone to forcible stops caused by the trolleys coming into contact with the belt, which can damage the equipment. Furthermore, when multiple trolleys are accumulated, the load on the stoppers and trolleys increases, leading to a high failure rate.

[0003] Therefore, it is necessary to provide an aerial suspension conveyor line to at least partially solve the above problems. Utility Model Content

[0071] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with embodiments of the present invention.

[0072] In order to fully understand the embodiments of the present invention, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

[0073] The utility model provides an aerial suspension conveyor line.

[0074] See also Figures 1 to 3 The overhead suspended conveyor line 1 includes a first rail 11 and a trolley 21. Specifically, the first rail 11 is arranged along the first horizontal direction D1 and has a first accommodating cavity 11a with an opening facing downward. Preferably, the first rail 11 is constructed as an integrally formed workpiece. The trolley 21 is movably connected to the first rail 11 along the first horizontal direction D1. The trolley 21 passes through the opening and protrudes downward from the first rail 11. Furthermore, the trolley 21 includes a frame 24 and a wheel set 25, and the wheel set 25 is connected to the frame 24. The number of the wheel sets 25 is at least two and they are spaced apart along the first horizontal direction D1. Please refer to Figure 3 and Figure 4The wheel assembly 25 includes a running wheel 262, which is located in the first accommodating cavity 11a and has its outer circumference abutting the inner bottom surface of the first rail 11. It should be noted that the first accommodating cavity 11a has upward-opening limiting grooves 11b, which extend along the first horizontal direction D1 and are arranged in pairs. Adjacent limiting grooves 11b are spaced apart along a second horizontal direction D2, which is perpendicular to the first horizontal direction D1. The running wheel 262 is partially located in the limiting grooves 11b to prevent the running wheel 262 from slipping relative to the first rail 11 along the second horizontal direction D2.

[0075] According to the aerial suspension conveyor line 1 of the present invention, a limiting groove 11b adapted to the wheel set 25 is provided in the first track 11, so that when the traveling trolley 21 moves along the first horizontal direction D1, the wheel set 25 will not deviate along the second horizontal direction D2, thereby ensuring the movement accuracy of the traveling trolley 21, reducing the wear of the wheel set 25 and the first track 11, and thus reducing the failure rate of the aerial suspension conveyor line 1.

[0076] For further information, see Figure 4 The traveling trolley 21 further includes a guide wheel 28, which is pivotally connected to the wheel set 25 around the vertical direction DH, and the outer peripheral surface of the guide wheel 28 abuts against the outer side surface of the adjacent limiting groove 11b along the second horizontal direction. Figure 3 In the embodiment, the first track 11 has a baffle 12 arranged along the first horizontal direction D1 to form a retaining groove 11b. It will be appreciated that the outer circumference of the guide wheel 28 abuts against the adjacent baffle 12 along the second horizontal direction D2. The guide wheel 28 cooperates with the running wheel 262 and the retaining groove 11b to ensure that the running wheel 262 moves accurately and smoothly along the first track 11.

[0077] See also Figure 2 It should be noted that the aerial suspension conveyor line described in the present invention is a belt-type conveyor line. It can be understood that the aerial suspension conveyor line 1 also includes a drive assembly 15, and part of the drive assembly 15 is located in the first accommodating chamber 11a. The drive assembly 15 is used to drive the walking trolley 21 to move along the first track 11. The drive assembly 15 includes a transmission belt 18, and the transmission belt 18 is constructed in a closed shape. The drive assembly 15 also includes a transmission member 16 and a first drive member 17. The first drive member 17 can be constructed as a motor, and the first drive member 17 is detachably connected to the first track 11. The first drive member 17 is connected to the transmission member 16 for transmission. The transmission member 16 is arranged along the second horizontal direction D2, and adjacent transmission members 16 are spaced along the first horizontal direction D1. The transmission belt 18 is wound around the adjacent transmission members 16 along the first horizontal direction D1, so that the first drive member 17 can drive the transmission belt 18 to operate.

[0078] See also Figures 2 to 5, the wheel set 25 also includes a bracket 261 and a clamping member 263. The bracket 261 is located in the first accommodating cavity 11a, and the walking wheel 262 is pivotally connected to the bracket 261 around the second horizontal direction D2. Along the second horizontal direction D2, the number of the walking wheels 262 is two and they are evenly distributed on both sides of the bracket 261. The clamping member 263 is movably connected to the bracket 261 along the vertical direction DH between a first position and a second position. The clamping member 263 at the first position abuts against the transmission belt 18 so that the trolley can move along with the transmission belt 18; the clamping member 263 at the second position disengages from the transmission belt 18 so that the transmission belt 18 idles. For example Figure 5 , the pressing member 263 is located at the second position.

[0079] See also Figures 4 to 6 The bracket 261 has a first mounting hole extending through it in the vertical direction DH. The wheel assembly 25 further includes a first connecting member 264 and a first elastic member 265. Specifically, the first connecting member 264 is movably connected to the first mounting hole in the vertical direction DH. The pressing member 263 is located above the bracket 261 and connected to the first connecting member 264. The first elastic member 265 is sleeved around the outer periphery of the first connecting member 264 and is located between the bracket 261 and the pressing member 263. It will be understood that the first elastic member 265 is used to drive the pressing member 263 to return from the second position to the first position.

[0080] Furthermore, the wheel set 25 includes a first wheel set 26 and a second wheel set 27, and the first wheel set 26 and the second wheel set 27 are spaced apart along the first horizontal direction D1. The overhead suspended conveyor line 1 also includes a stopper 32 and a limiting member 13. Specifically, the stopper 32 is detachably connected to the first rail 11, and the stopper 32 has a switchable blocking state and a release state. The limiting member 13 is arranged along the first horizontal direction D1 and is located below the first rail 11, and the limiting member 13 is connected to the first rail 11. It should be noted that when the stopper 32 is in the blocking state, the stopper 32 is used to drive the clamping member 263 at one of the first wheel set 26 and the second wheel set 27 to move from the first position to the second position; accordingly, the limiting member 13 is used to drive the clamping member 263 at the other of the first wheel set 26 and the second wheel set 27 to move from the first position to the second position, thereby disengaging the walking trolley 21 from the transmission belt 18.

[0081] See also Figure 2 as well as Figures 4 to 6, along the direction of travel of the trolley 21 (see the arrow in the figure), in front of the first wheel set 26 and the second wheel set 27. Furthermore, the aerial suspension conveyor line 1 also includes a mating component 22 and a plug-in component 23. The mating component 22 is connected to the first wheel set 26, and the plug-in component 23 is connected to the second wheel set 27. Along the first horizontal direction D1, the mating component 22 closest to the stopper 32 is used to abut against the stopper 32, so that the first wheel set 26 moves from the first position to the second position.

[0082] It can be understood that the structures of the first wheel group 26 and the second wheel group 27 are basically the same. The structures of the first wheel group 26 and the second wheel group 27 are briefly described below. The first wheel group 26 includes a bracket 261, a running wheel 262, a clamping member 263, a first connecting member 264 and a first elastic member 265. Specifically, the running wheel 262 is pivotally connected to the bracket 261 about the second horizontal direction D2. Along the second horizontal direction D2, the number of running wheels 262 is two and evenly distributed on both sides of the bracket 261. The first connecting member 264 is movably connected to the bracket 261 along the vertical direction DH, and the clamping member 263 is connected to the first connecting member 264. The first elastic member 265 is sleeved on the outer periphery of the first connecting member 264, and the first elastic member 265 is located between the bracket 261 and the clamping member 263. The mating member 22 is pivotally connected to the first connecting member 264 about the second horizontal direction D2. The second wheel assembly 27 includes a bracket 271, a running wheel 272, a pressing member 273, a first connecting member 274, and a first elastic member 275. The second wheel assembly 27 also includes a contact wheel 276, which is pivotally connected to the first connecting member 274 about a second horizontal direction D2. The function of the contact wheel 276 will be described later.

[0083] Please refer to Figure 2 , along the first horizontal direction D1, the number of the traveling trolleys 21 is at least two, for example Figure 2 In the figure, there are two trolleys 21. Along the travel direction of the trolleys 21, the mating member 22 on the trailing trolley 21 can abut against the plug-in member 23 on the leading trolley 21. The limiting member 13 is used to drive the pressing member 273 on the second wheel assembly 27 from the first position to the second position, disengaging the trolley 21 from the transmission belt 18 and thereby stopping the trolley 21 from moving forward.

[0084] See also Figures 4 to 6The stopper 32 includes a fixed seat 33, a second driving member 34, and a blocking member 35. The fixed seat 33 is connected to the first rail 11. One end of the second driving member 34 is pivotally connected to the fixed seat 33 about the first horizontal direction D1. The second driving member 34 can be constructed as a cylinder, and the second driving member 34 has an execution end 34a. The blocking member 35 is pivotally connected to the fixed seat 33 about the first horizontal direction D1, and the blocking member 35 is pivotally connected to the execution end 34a about the first horizontal direction D1. It can be understood that the execution end 34a is used to drive the blocking member 35 to pivot relative to the fixed seat 33 about the first horizontal direction D1. The blocking member 35 includes a supporting portion 35a. When the stopper 32 is in the blocking state, the supporting portion 35a abuts against the mating member 22 and is located above the mating member 22. The plug-in component 23 includes a guide surface 23b and a supporting surface 23a located at its bottom. Along the first horizontal direction D1, the supporting surface 23a is closer to the second wheel set 27 than the guide surface 23b. It should be noted that the supporting surface 23a is tilted, and the supporting surface 23a is tilted relative to the first horizontal direction D1 and the vertical direction DH. The supporting surface 23a has a first end and a second end spaced apart along the first horizontal direction D1. The first end is located above the second end, and along the traveling direction of the trolley 21, the first end is located in front of the second end. In other words, along the traveling direction of the trolley 21, the supporting surface 23a is constructed as an uphill surface. The guide surface 23b is tilted relative to the first horizontal direction D1 and the vertical direction DH, and the guide surface 23b is tilted upward relative to the supporting surface 23a.

[0085] The accumulation process of at least two traveling carriages 21 is described below.

[0086] See also Figure 2 as well as Figures 4 to 6 , Figure 2 In the figure, along the traveling direction of the traveling trolley 21, the traveling trolley 21 at the front is called trolley 1, and the traveling trolley 21 at the rear is called trolley 2. It can be understood that the aerial suspension conveyor line 1 is equipped with an electric control system so that various components can be coordinated and operated.

[0087] When trolley No. 1 moves along the first track 11, the clamping member 263 (clamping member 273) at trolley No. 1 is located in the first position, thereby following the movement of the transmission belt 18. After the wheel group 25 of trolley No. 1 moves to the position limiting member 13, the clamping member 263 at the first wheel group 26 is still located in the first position; the abutting wheel 276 at the second wheel group 27 abuts against the bottom surface of the position limiting member 13, thereby causing the clamping member 273 at the second wheel group 27 to move from the first position to the second position. At this time, trolley No. 1 is in contact with the transmission belt 18 by the clamping member 263, thereby causing trolley No. 1 to move along the first track 11. When trolley No. 1 moves to a position close to the stopper 32, the electronic control system controls the stopper 32 to switch to a blocking state. After the engaging member 22 at the first wheel set 26 of the No. 1 trolley abuts against the supporting portion 35a, the engaging member 22 drives the pressing member 263 to move from the first position to the second position, thereby disengaging the first wheel set 26 from the transmission belt 18. On the other hand, the No. 1 trolley is stopped by the stopper 32, thereby stopping the No. 1 trolley from moving forward.

[0088] When trolley No. 2 moves along the first track 11, the clamping member 263 (clamping member 273) at trolley No. 2 is located in the first position, thereby following the movement of the transmission belt 18. After the wheel group 25 of trolley No. 2 moves to the limiting member 13, the clamping member 263 at the first wheel group 26 is still located in the first position; the abutting wheel 276 at the second wheel group 27 abuts against the bottom surface of the limiting member 13, thereby causing the clamping member 273 at the second wheel group 27 to move from the first position to the second position. At this time, trolley No. 2 is in contact with the transmission belt 18 by the clamping member 263, thereby causing trolley No. 2 to move along the first track 11. When trolley No. 2 moves to a position close to trolley No. 1, trolley No. 2 continues to move, and the matching member 22 first contacts the guide surface 23b, and then moves to contact the abutting surface 23a. Thus, the clamping member 263 moves from the first position to the second position. Since the abutting surface 23a forms an upslope surface, the No. 2 trolley stops moving after losing power.

[0089] In this way, at least two trolleys 21 complete the accumulation process. It can be understood that in order to make the power switching of the trolley 21 smoother, the supporting portion 35a can also be provided with a corresponding inclined guide surface. The plug-in member 23 can also have a blocking portion connected to the abutment surface 23a to avoid collision between adjacent trolleys 21 along the first horizontal direction D1. In addition, the limiting member 13 can be constructed as an integrally formed bending part, and the limiting member 13 has a first guide portion 13a and a second guide portion 13b. The first guide portion 13a and the second guide portion 13b are bent upward relative to the limiting member body. The second guide portion 13b is used to guide the trolley to abut against the limiting member 13, so that the clamping member 273 at the second wheel group 27 is disengaged from the transmission belt 18. The first guide portion 13a is used to guide the trolley 21 to leave the limiting member 13.

[0090] After the electronic control system switches the stopper 32 to the release state, the first elastic member 265 acts to move the holding member 263 of trolley No. 1 from the second position to the first position, thereby re-engaging the transmission member 18 and allowing trolley No. 1 to continue traveling in the first horizontal direction D1. Accordingly, the plug-in member 23 of trolley No. 1 disengages from the mating member 22 of trolley No. 2. The holding member 263 of trolley No. 2, under the action of the first elastic member 265, moves from the second position to the first position, thereby re-engaging the transmission member 18 and allowing trolley No. 2 to continue traveling in the first horizontal direction D1.

[0091] Return to Reference Figure 1 and Figure 2 , those skilled in the art know that the aerial suspension conveyor line 1 may further include a hanger 31 , which is connected to the traveling trolley 21 and is located below the traveling trolley 21 , and the hanger 31 is used to carry the cargo 100 .

[0092] According to the aerial conveyor line of the present invention, the trolley's travel path is precise and does not deviate along the second horizontal direction, reducing wear on the running wheels and the first track, and also lowering the equipment's failure rate. Furthermore, during the trolley's accumulation process, the wheel group's power switching is highly organized, effectively reducing the impact and load on the stopper and the trolley. The accumulation of the trolley can play an important role in the inbound and outbound management of the aerial conveyor line, making the aerial conveyor line's scheduling more efficient and improving the efficiency of cargo transportation.
