Description

Technical Field

[0001] The present application relates to the field of suspension transmission technology, and in particular to a suspension chain and transmission equipment. Background Art

[0002] Suspension chain is a three-dimensional closed-loop continuous conveying system, suitable for the automated transmission of items within and between workshops. Suspension chain is widely used in machinery, electronics, light industry, food and other industries.

[0003] In the related art, the suspension chain generally includes at least one walking wheel unit, at least one guide wheel unit and a connecting piece. The walking wheel unit includes a walking wheel connecting rod, the guide wheel unit includes a guide wheel connecting rod, the connecting piece is provided with a walking wheel connecting hole and a guide wheel connecting hole, the walking wheel connecting rod is rotatably inserted into the walking wheel connecting hole, the guide wheel connecting rod is rotatably inserted into the guide wheel connecting hole, and the guide wheel unit is connected to the walking wheel unit through the connecting piece.

[0004] With respect to the above-mentioned related technologies, the suspension chain is driven by the traction device to circulate along a predetermined path on the guide rail, but the suspension chain may sometimes get stuck when moving on the guide rail. Once a certain point of the suspension chain is stuck, the subsequent chains will continue to move forward under the action of the traction device, causing serious blockage of the suspension chain on the guide rail. Summary of the invention

[0005] In order to prevent the suspension chain from being seriously blocked on the guide rail, the present application provides a suspension chain and a transmission device.

[0006] In the first aspect, the present application provides a suspension chain and a transmission device, which adopts the following technical solutions:

[0007] A suspension chain comprises at least one chain module, wherein the chain module comprises a walking wheel unit, a guide wheel unit and a connecting piece for connecting the walking wheel unit and the guide wheel unit, wherein the connecting piece comprises a walking wheel connecting hole for a walking wheel connecting rod to pass through, a guide wheel connecting hole for a guide wheel connecting rod to pass through and a sliding cavity, wherein the sliding cavity is connected to the walking wheel connecting hole and / or the guide wheel connecting hole so that the walking wheel connecting rod and / or the guide wheel connecting rod can slide into the sliding cavity.

[0008] By adopting the above technical scheme, the suspension chain slides on the guide rail, and when the walking wheel unit or guide wheel unit of the suspension chain is stuck on the guide rail, the walking wheel unit or guide wheel unit will stop on the guide rail. Due to the action of the traction device and the tensioning device, the suspension chain will continue to move forward, but because the stuck suspension chain cannot move, the rear suspension chain will keep moving toward the stuck position, and the rear walking wheel unit or guide wheel unit will keep pushing the front guide wheel unit or walking wheel unit, so that the suspension chain will accumulate on the guide rail. If it is the suspension chain in the related technology, the walking wheel unit and the guide wheel unit will rotate, so that the walking wheel unit and the guide wheel unit will tilt on the predetermined track of the guide rail, so that the guide wheel unit and the guide wheel unit will abut against the inner side wall of the predetermined track, making the suspension chain more seriously blocked on the predetermined track. After the staff solves the stuck accident, it is necessary to check other suspension chains to prevent other suspension chains from blocking the predetermined track.

[0009] After using the suspension chain of the present application, when the suspension chain gets stuck and the suspension chain continues to move forward, the wheel connecting rod of the walking wheel unit or the guide wheel connecting rod of the guide wheel unit slides in the sliding cavity of the connecting piece, causing the walking wheel unit and the guide wheel unit to shrink and reduce the distance between the walking wheel unit and the guide wheel unit, so that the suspension chain can still move forward, and the walking wheel unit and the guide wheel unit are not easily stuck on the predetermined track, thereby reducing the workload of the staff to check other suspension chains and reducing the probability of damage to the walking wheel unit and the guide wheel unit.

[0010] Optionally, the running wheel connection hole passes through a group of opposite side surfaces of the connecting member, the running wheel connection hole is connected to the sliding cavity, and the guide wheel connection hole is connected to another group of opposite side surfaces of the connecting member.

[0011] By adopting the above technical solution, the wheel connecting hole is connected to the sliding cavity, so that the wheel unit passing through the wheel connecting hole can slide in the sliding cavity, thereby enabling relative movement between the wheel unit and the guide wheel unit.

[0012] Optionally, the guide wheel connection hole passes through a group of relative side surfaces of the connecting member, the guide wheel connection hole is connected to the sliding cavity, and the running wheel connection hole is connected to another group of relative side surfaces of the connecting member.

[0013] By adopting the above technical solution, the guide wheel connecting hole is connected to the sliding cavity, so that the guide wheel unit passing through the guide wheel connecting hole slides in the sliding cavity, thereby enabling relative movement between the walking wheel unit and the guide wheel unit.

[0014] Optionally, the sliding cavity is connected to the end surface of the connecting member close to the guide wheel unit.

[0015] By adopting the above technical solution, after the sliding cavity and the end face of the connecting piece close to the guide wheel unit are connected, the connecting piece is C-shaped as a whole, which ensures the structural strength of the connecting piece while minimizing the material used in the connecting piece and saving costs.

[0016] Optionally, the walking wheel unit includes two walking wheel side baffles arranged parallel to each other, a walking wheel roller group connected to the walking wheel side baffles and having a walking wheel, and a walking wheel connecting rod arranged at both ends of the walking wheel side baffles, and the walking wheel connecting rod is passed through the walking wheel connecting hole.

[0017] By adopting the above technical solution, the running wheel unit and the guide wheel unit are respectively connected to the two ends of the connecting member, and the running wheel unit and the guide wheel unit are connected through the connecting member.

[0018] Optionally, the guide wheel unit includes two guide wheel side baffles arranged parallel to each other, a guide wheel roller group connected to the guide wheel side baffles and having a guide wheel, and a guide wheel connecting rod arranged at both ends of the guide wheel side baffles, and the guide wheel connecting rod is passed through the guide wheel connecting hole.

[0019] By adopting the above technical solution, the guide wheel connecting rod is arranged at both ends of the walking wheel side baffle, and the guide wheel connecting rod is passed through the guide wheel connecting hole, so that the guide wheel unit is connected to the connecting piece through the guide wheel connecting rod. In addition, if the sliding cavity and the guide wheel connecting hole are connected, the guide wheel connecting rod slides in the sliding cavity, causing relative movement between the walking wheel connecting rod and the guide wheel connecting rod.

[0020] Optionally, a clearance groove is provided on the side of the guide wheel side baffle away from the other guide wheel side baffle, and the guide wheel is located in the clearance groove.

[0021] By adopting the above technical solution, the guide wheel is located in the give way groove, so that the distance from the guide wheel to the middle of the two side baffles is reduced. Since the suspension chain circulates on the guide rail, the guide rail has a bend. When the guide wheel unit moves at the bend of the guide rail, the guide wheel may rub against the inner wall of the guide rail, causing serious wear of the guide wheel and the guide rail. By reducing the distance between the guide wheel and the side baffle, the guide wheel is not easily worn against the inner wall of the guide rail.

[0022] Optionally, the clearance groove includes a horizontal section and inclined sections arranged at both ends of the horizontal section, and the horizontal section is flush with the end surface of the guide wheel.

[0023] By adopting the above technical solution, the horizontal section is flush with the end surface of the guide wheel, so that the guide wheel is not prone to friction with the horizontal section when in use.

[0024] Optionally, the angle between the inclined section and the horizontal section is greater than 90°.

[0025] By adopting the above technical solution, in addition, the angle between the inclined section and the horizontal section is different, and the depth of the recessed groove is also different. The staff can change the depth of the recessed groove by designing the angle between the inclined section and the horizontal section.

[0026] In a second aspect, the present application provides a transmission device, which adopts the following technical solution:

[0030] 1. The running wheel unit is inserted into the running wheel connection hole, the guide wheel unit is inserted into the guide wheel connection hole, and the sliding cavity is connected with the running wheel connection hole or the guide wheel connection hole, so that the running wheel unit and the guide wheel unit can move relative to each other;

[0031] 2. The distance between the guide wheel and the side baffle is reduced by the clearance groove, so that the guide wheel is not easy to wear against the inner wall of the guide rail;

[0032] 3. When the suspension chain gets stuck and continues to move forward, the wheel connecting rod of the walking wheel unit slides in the sliding cavity of the connecting piece, causing the walking wheel unit and the guide wheel unit to shrink, reducing the distance between the walking wheel unit and the guide wheel unit, so that the suspension chain can still move forward, and the walking wheel unit and the guide wheel unit are not easy to get stuck on the predetermined track.

[0049] The following is combined with Figure 1-15 This application is described in further detail.

[0050] The embodiments of the present application disclose a suspension chain and a transmission device.

[0051] Reference Figure 1The suspension chain includes at least one chain module 7, and the chain module 7 includes a running wheel unit 2, a guide wheel unit 3, and a connecting member 1 for connecting the running wheel unit 2 and the guide wheel unit 3.

[0052] See also Figure 2 and Figure 3 The connector 1 can be a cube or a strip. For practical application, this embodiment is described with the connector 1 being a strip. The two ends along the length direction of the connector 1 are defined as a first end 11 and a second end 12, and the four circumferential side surfaces of the connector 1 are defined as a first side surface 13, a second side surface 14, a third side surface 15 and a fourth side surface 16, wherein the first side surface 13 and the third side surface 15 are arranged opposite to each other, and the second side surface 14 and the fourth side surface 16 are arranged opposite to each other.

[0053] The connecting member 1 is provided with a running wheel connecting hole 17, a guide wheel connecting hole 18 and a sliding cavity 19. The shapes of the running wheel connecting hole 17 and the guide wheel connecting hole 18 can be the same or different. Conventionally, the running wheel connecting hole 17 and the guide wheel connecting hole 18 are generally set to be cylindrical, so that the connecting member 1 and the guide wheel unit 2, and the connecting member 1 and the running wheel unit 3 can all rotate relative to each other. The running wheel connecting hole 17 and the guide wheel connecting hole 18 can also be other shapes, as long as they can achieve the expected effect of the present application.

[0054] The walking wheel connecting hole 17 passes through the first side surface 13 and the third side surface 15, and the guide wheel connecting hole 18 passes through the second side surface 14 and the fourth side surface 16, that is, the walking wheel connecting hole 17 and the guide wheel connecting hole 18 respectively pass through a group of opposite sides of the connecting member 1, and the walking wheel connecting hole 17 is arranged close to the second end 12, and the guide wheel connecting hole 18 is arranged close to the first end 11.

[0055] The sliding cavity 19 is communicated with the wheel connecting hole 17 , and the sliding cavity 19 is also connected with the first side surface 13 and the third side surface 15 , and after the connection, the sliding cavity 19 and the wheel connecting hole 17 form a waist-shaped hole.

[0056] See also Figure 4 In order to save materials and reduce costs, one end of the sliding cavity 19 away from the running wheel connecting hole 17 is connected to the end surface of the first end 11, so that the connecting member 1 is C-shaped as a whole.

[0057] See also Figure 5 The wheel unit 2 includes two parallel wheel side baffles 21, a wheel roller group 22 and a wheel connecting rod 23. The wheel roller group 22 is connected to the wheel side baffles 21, and the wheel connecting rod 23 is arranged at the end of the wheel side baffles 21.

[0058] The walking wheel roller group 22 includes two walking wheels 221 and a walking wheel fixing rod 222. The end faces of the two walking wheels 221 are parallel, and the two walking wheels 221 are coaxially arranged. The walking wheel fixing rod 222 is fixedly penetrated on the two walking wheel side baffles 21, and the two ends of the walking wheel fixing rod 222 respectively protrude from the two walking wheel side baffles 21. The two ends of the walking wheel fixing rod 222 are coaxially connected to the two walking wheels 221, so that the walking wheels 221 are rotatably connected to the walking wheel side baffles 21 through the walking wheel fixing rod 222.

[0059] Both ends of the wheel side baffle 21 are provided with a wheel connecting rod 23, the wheel connecting rod 23 passes through the two wheel side baffles 21, and the two ends of the wheel connecting rod 23 respectively protrude from the two wheel side baffles 21, the wheel connecting rod 23 passes through the wheel connecting hole 17 of the connecting member 1, and is connected. The shape of the wheel connecting rod 23 can be cylindrical or other shapes such as a cube. In order to make it more convenient to connect the wheel connecting rod 23 to the connecting member 1, the wheel connecting rod 23 in this embodiment is illustrated by taking a cylindrical shape as an example.

[0060] See also Figure 6 The guide wheel unit 3 includes two mutually parallel guide wheel side baffles 31, a guide wheel roller group 32 and a guide wheel connecting rod 33 arranged at both ends of the guide wheel side baffles 31. The guide wheel roller group 32 is connected to the guide wheel side baffles 31, and the guide wheel connecting rod 33 is arranged at the end of the guide wheel side baffles 31.

[0061] The guide wheel roller group 32 includes two guide wheels 321 and a guide wheel fixing rod 322. The guide wheel roller group 32 of the guide wheel unit 3 and the running wheel roller group 22 of the running wheel unit 2 are only named differently, and the structures and connection methods are basically the same.

[0062] See also Figure 6 and Figure 7 A concave clearance groove 311 is provided on the side of one guide wheel side baffle plate 31 away from the other guide wheel side baffle plate 31. The clearance groove 311 can be formed by later processing, or the guide wheel side baffle plate 31 can be directly die-cast during production. After the guide wheel roller group 32 is connected to the guide wheel side baffle plate 31, the guide wheel 321 is located in the clearance groove 311, so that the distance between the two adjacent guide wheels 321 is shorter.

[0063] The clearance groove 311 includes a horizontal section 312 and inclined sections 313 disposed at both ends of the horizontal section 312. The horizontal section 312 is flush with the end surface of the guide wheel 321. There is an angle between the inclined section 313 and the horizontal section 312, and the angle of the angle is greater than 90 degrees. When manufacturing the guide wheel side baffle 31, the staff can design the angle between the horizontal section 312 and the inclined section 313 according to the actual production needs, so that the depth of the guide wheel 321 in the clearance groove 311 is different.

[0064] When the walking wheel unit 2 is connected to the connecting member 1, the walking wheel connecting rod 23 passes through one of the walking wheel side baffles 21, the walking wheel connecting hole 17 of the connecting member 1 and the other walking wheel side baffle 21 in sequence, and then the walking wheel connecting rod 23 is fixed to the walking wheel side baffle 21, so that the walking wheel connecting rod 23 slides in the sliding cavity 19.

[0065] When the guide wheel unit 3 is connected to the connecting member 1, the guide wheel connecting rod 33 passes through one of the guide wheel side baffles 31, the guide wheel connecting hole 18 of the connecting member 1 and the other guide wheel side baffle 31 in sequence, and then the guide wheel connecting rod 33 is fixed to the guide wheel side baffle 31, and the guide wheel connecting rod 33 is perpendicular to the running wheel connecting rod 23. After the guide wheel unit 3 and the running wheel unit 2 are respectively connected to the connecting member 1, the axis of the guide wheel 321 is perpendicular to the axis of the running wheel 221.

[0066] See also Figure 8 and Fig. 9 This embodiment also discloses a transmission device, which includes a traction device 4, a tensioning device 5, a guide rail 6 and the above-mentioned suspension chain. The guide rail 6 has a predetermined track 61 for the suspension chain to move. The cross-sectional area of ​​the guide rail 6 along its extension direction is generally rectangular. Any other shape that allows the suspension chain to run normally in the guide rail 6 is acceptable.

[0067] The guide rail 6 is generally placed horizontally when in use. The four inner side walls of the guide rail 6 are named according to their positions, namely, the upper groove wall, the lower groove wall, the left groove wall and the right groove wall. When the suspension chain moves on the predetermined track 61, the wheel surface of the running wheel 221 of the running wheel unit 2 abuts against the lower groove wall of the guide rail 6, and the wheel surface of the guide wheel 321 of the guide wheel unit 3 abuts against the left groove wall and / or the right groove wall of the guide rail 6.

[0068] See also Fig.10 The traction device 4 is arranged on the guide rail 6 and connected to the suspension chain. The traction device 4 can be a traction machine, a motor, etc. The traction device 4 provides traction for the suspension chain, so that the suspension chain moves within the predetermined track 61 of the guide rail 6; the tensioning device 5 is arranged on the guide rail 6 and connected to the suspension chain. The tensioning device 5 can be a tensioning wheel, etc. The tensioning device 5 keeps the suspension chain in a tensioned state, so that the suspension chain moves more stably within the predetermined track 61.

[0069] Although the suspension chain moves within the predetermined track 61 of the guide rail 6 , the suspension chain may still get stuck on the guide rail 6 due to the complex working environment.

[0070] The suspension chain is defined to move in the clockwise direction in the figure. When the walking wheel unit 2 or the guide wheel unit 3 of the suspension chain gets stuck on the predetermined track 61 of the guide rail 6, the walking wheel unit 2 or the guide wheel unit 3 will stop on the guide rail 6. Point A in the figure is the point where the suspension chain is simulated to have an accident on the predetermined track 61.

[0071] The suspension chain at point A cannot move due to an accident, but under the traction of the traction device 4, the walking wheel unit 2 and the guide wheel unit 3 of the suspension chain except point A will continue to move, especially the suspension chain between point A and the traction device 4, which is in a stretched state due to the action of the traction device 4. The suspension chain between the tensioning device 5 and point A will still move toward point A under the drive of the tensioning device 5, and continue to impact and squeeze point A.

[0072] At point A, except for the wheel unit 2 or guide wheel unit 3 where the accident occurred, the guide wheel unit 3 and the wheel unit 2 behind it will continue to move toward point A, and will be blocked and piled up at point A. It is worth noting that in the related art, the wheel unit 2 and the guide wheel unit 3 of the suspension chain can rotate relative to each other so that the suspension chain can adapt to the curved guide rail 6. When the accident occurs, the wheel unit 2 and the guide wheel unit 3 moving toward point A are tilted in the predetermined track 61 of the guide rail 6 due to squeezing and blocking, so that the wheel unit 2 and the guide rail 6 unit are in contact with the inner side wall of the predetermined track 61, resulting in more wheel units 2 and guide rail 6 units being stuck on the guide rail 6, making the suspension chain more seriously blocked on the predetermined track 61. After the staff has handled the accident at point A, it is necessary to check other parts of the suspension chain except point A or even the entire suspension chain, which greatly increases the workload of the staff.

[0073] After an accident occurs on the guide rail 6, the suspension chain of the present application moves from the tensioning device 5 to point A toward point A. At this time, the wheel connecting rod 23 of the wheel unit 2 slides in the sliding cavity 19 of the connecting member 1, causing the wheel unit 2 and the guide wheel unit 3 to shrink, thereby reducing the distance between the wheel unit 2 and the guide wheel unit 3, making it difficult for an excessive extrusion pressure to be generated between the wheel unit 2 and the guide wheel unit 3, reducing the inclination of the wheel unit 2 and the guide wheel unit 3 on the guide rail 6 and abutting against the inner wall of the guide rail 6, thereby making it difficult for the wheel unit 2 and the guide wheel unit 3 to get stuck on the predetermined track 61, reducing the workload of the staff in checking for blockage from point A to the tensioning device 5, and reducing the probability of damage to the wheel unit 2 and the guide wheel unit 3.

[0074] See also Fig. 9In actual production, in order to facilitate the staff to hang the workpiece on the suspension chain or other operations are required for the work, the guide rail 6 is often provided with one or more arc-shaped undulating sections, and the undulating section has two slope sections, namely, ascending and descending. When the guide wheel unit 3 in the related art moves on the ascending and descending slope sections, the end face of the guide wheel 321 of the guide wheel unit 3 will rub against the upper groove wall or the lower groove wall of the guide rail 6, causing the guide wheel 321 of the guide wheel unit 3 to be seriously worn, and the guide wheel unit 3 is in an inclined state. If the guide wheel 321 is firmly abutted against the inner side wall of the guide rail 6 or the friction force is large enough, the guide wheel unit 3 will be stuck on the guide rail 6. By providing a clearance groove 311 on the guide wheel side baffle 31, the distance between the two adjacent guide wheels 321 is reduced, and the length of the guide wheel 321 protruding from the guide wheel side baffle 31 is also reduced, so that when the guide wheel unit 3 moves in the guide rail 6, the guide wheel 321 is not easy to contact the upper groove wall and the lower groove wall of the guide wheel 321.

[0075] Embodiment 2:

[0076] The difference between this embodiment and the first embodiment is only that the position of the sliding cavity 19 is different.

[0077] See also Fig.11 and Fig.12 The sliding cavity 19 is connected with the second side surface 14 and the fourth side surface 16, and the sliding cavity 19 is connected with the guide wheel connecting hole 18. After the connection, the sliding cavity 19 and the guide wheel connecting hole 18 form a waist-shaped hole.

[0078] See also Fig.13 When the chain is connected, the running wheel connecting rod 23 is inserted into the running wheel connecting hole 17, and the guide wheel connecting rod 33 is fixedly inserted into the guide wheel connecting hole 18, so that the guide wheel connecting rod 33 can slide from the guide wheel connecting hole 18 into the sliding cavity 19.

[0079] Embodiment 3:

[0080] The difference between this embodiment and the first embodiment is only that the arrangement of the running wheel connecting hole 17 is different.

[0081] See also Fig.14 and Fig.15 The running wheel connecting hole 17 is a waist-shaped hole, the running wheel connecting rod 23 is slidably penetrated in the running wheel connecting hole 17, the guide wheel connecting rod 33 is penetrated in the guide wheel connecting hole 18 and can slide into the sliding cavity 19, so that the running wheel connecting rod 23 and the guide wheel connecting rod 33 both slide on the connecting member 1.

[0082] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
