Description

Technical Field

[0001] This invention relates to the technical field of transmission tools, and more specifically to a transmission module that allows personnel to pass through. Background Technology

[0002] The existing transmission module cannot open a walking channel, which means that users can only walk along the transmission direction of the transmission module to the end and then go around to the other side of the transmission module. This will hinder users from quickly handling abnormalities and reduce the convenience of operation. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a transmission module that facilitates passage and has transmission function, thereby improving the ease of operation of the transmission module.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0005] A transmission module that allows personnel to pass through includes:

[0006] The support assembly includes a first support and a second support spaced apart along a first direction.

[0007] The roller assembly includes two first connecting rods, two second connecting rods, and a plurality of rollers spaced apart along the transmission direction of the transmission module. The two first connecting rods are spaced apart along a second direction perpendicular to the first direction and are both fixed to the top of the first support. One end of one second connecting rod is rotatably connected to another second connecting rod, and the opposite end of the second connecting rod moves toward or away from the second support, so that the transmission module has a closed state or an open state. In the closed state, the second connecting rod overlaps the top of the second support. A portion of the rollers are connected between the two first connecting rods, and another portion of the rollers are connected between the two second connecting rods. The rollers can rotate about a central axis oriented along the second direction.

[0008] Drive assembly for driving the drum to rotate; and

[0009] Two nitrogen springs are provided, with the extension end of each nitrogen spring rotatably connected to a second connecting rod and the mounting end of the nitrogen spring rotatably connected to the first support. The nitrogen springs are used to drive the second connecting rod to move away from the second support to clear the passage between the first support and the second support.

[0010] In some possible implementations, it also includes:

[0011] A micro switch, located at the top of the second support, when in the closed state, has the second connecting rod abutting against the micro switch to turn it on; and

[0012] The controller is configured to output a first signal based on the on signal of the micro switch and to output a second signal based on the off signal of the micro switch, and the drive component is configured to operate based on the first signal and to stop operating based on the second signal.

[0013] In some possible implementations, a gap exists between the opposite ends of the second link and the first link, and the transmission module further includes:

[0014] Two rotating components are provided. One rotating component is located away from the second support on one side of the nitrogen spring. The rotating component includes a first rotating shaft and a rotating rod. The rotating rod is located away from the roller on the same side of the first connecting rod and the second connecting rod. The first rotating shaft protrudes from the first connecting rod along the second direction and passes through one end of the rotating rod. The rotating rod can rotate around the first rotating shaft. The other end of the rotating rod is fixed to the second connecting rod.

[0015] In some possible implementations, the nitrogen spring is located away from the roller on the same side of the first connecting rod and the second connecting rod, and the transmission module further includes:

[0016] Two second rotating shafts, one of which passes through the mounting end of the nitrogen spring, and the second rotating shaft protrudes from the first support along the second direction; and

[0017] Two third rotating shafts, one of which passes through the telescopic end of a nitrogen spring, the third rotating shaft protruding from the second connecting rod along the second direction, and the nitrogen spring being rotatable around the third rotating shaft and the second rotating shaft.

[0018] In some possible implementations, the rotating assembly further includes:

[0019] The limiting member is located on one side of the first rotating shaft relative to the first support. When it is in the open state, the end of the rotating rod connected to the first rotating shaft abuts against the end face of the limiting member away from the second support.

[0020] In some possible implementations, the limiting member has a first end face, a second end face, and an inclined surface. The first end face is disposed away from the second support, the second end face is perpendicular to the first end face and disposed relative to the first rotating shaft, and the inclined surface connects the first end face and the second end face. The rotating rod has a third end face, which includes a first region, an arcuate region, an inclined surface region, and a second region connected in sequence. When in the open state, the first region is attached to the first end face, and the arcuate region is disposed at a distance from the second end face. The second region is disposed parallel to the first region and closer to the second connecting rod. The arcuate region is curved away from the limiting member, and the angle between the inclined surface region and the second region is equal to the angle between the inclined surface and the first end face.

[0021] In some possible implementations, the transmission module further includes:

[0022] Two handles are provided, one of which is located at the end of the second link away from the first link. The handle is positioned away from the second support or away from the roller. The connection point between the handle and the second link is further away from the first link than the connection point between the nitrogen spring and the second link.

[0023] In some possible implementations, the handle is disposed away from the second support and includes:

[0024] Two first handles are spaced apart along the arrangement direction of the rollers connected to the second connecting rod; and

[0025] The second grip section, together with the two first grip sections and the second connecting rod, forms a cavity.

[0026] In some possible implementations, the driving component includes:

[0027] The driving component is fixed to the first support or the first connecting rod; and

[0028] A transmission ring is driven to connect the drive unit and each of the rollers.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] Each second link has one end rotatably connected to a first link, and the opposite end of the second link moves towards or away from the second support (driven by a nitrogen spring), allowing the transmission module to be in a closed or open state. In the closed state, multiple rollers can be laid flat to form a transmission channel. In the open state, the transmission module can avoid the walking path between the first and second supports, reducing the distance personnel need to pass through, thus improving the ease of passage of the transmission module. Therefore, the transmission module has both transmission function and improves ease of passage, thereby enhancing the operational convenience of the transmission module.

[0040] Reference Figure 1 This application provides a transmission module for personnel passage, hereinafter referred to as the transmission module. The transmission module includes a support assembly 10, a roller assembly 20, a drive assembly, and two nitrogen springs 40. The support assembly 10 includes a first support 11 and a second support 12 spaced apart along a first direction X. The roller assembly includes two first connecting rods 21, two second connecting rods 22, and a plurality of rollers 23 spaced apart along the transmission direction of the transmission module. The two first connecting rods 21 are spaced apart along a second direction Y perpendicular to the first direction X and are both fixed to the top of the first support 11. For example, the first connecting rods 21 can be fixed to the first support 11 by screws. One end of a second connecting rod 22 is rotatably connected to a first connecting rod 21, and the other end of the second connecting rod 22 moves toward or away from the second support 12, so that the transmission module has a closed state or an open state (see reference). Figure 1When in the closed state, the second link 22 is connected to the top of the second support 12. A portion of the roller 23 is connected between the two first links 21, and another portion of the roller 23 is connected between the two second links 23. The roller can rotate about a central axis oriented in the second direction Y. For example, each first link 21 and each second link 22 may have a mounting hole (not shown), and each end of the roller 23 along the second direction Y may be connected to a pin (not shown). The pin can be disposed in the mounting hole to allow the roller 23 to rotate about the central axis. A drive assembly is used to drive the roller 23 to rotate. The telescopic end of each nitrogen spring 40 is rotatably connected to a second link 22, and the mounting end of the nitrogen spring 40 is rotatably connected to the first support 11. The nitrogen spring 40 is used to drive the second link 22 to move away from the second support 12 to clear the walking passage between the first support 11 and the second support 12. At this time, personnel located on one side of the transmission module can walk from the walking passage to the opposite side of the transmission module. In practical application, the end of the second support 12 away from the first support 11 and the end of the first support away from the second support can both be connected to a fixed roller conveyor. The fixed roller conveyor may include a support, two connecting rods fixed to the support, and a roller rotatably connected to the two connecting rods. In practical use, the drive assembly can first stop operation, and then the user can lift the second connecting rod 22 away from the second support 12. Afterward, the nitrogen spring 40 continues to push the second connecting rod 22 to rotate away from the second support 12 to clear the travel path. When it is necessary to transport materials, the user can push the second connecting rod 22 back to its original position. Under the action of gravity, the second connecting rod 22 can continue to rotate and engage with the second support 12. Then, the drive assembly can resume operation to transport materials.

[0041] In this application, one end of each second link 22 is rotatably connected to a first link 21, and the opposite end of the second link 22 moves toward or away from the second support 12 (push by the nitrogen spring 40), so that the transmission module has a closed state or an open state. When in the closed state, multiple rollers can be laid flat to form a transmission channel. When in the open state, the transmission module can avoid the walking channel between the first support 11 and the second support 12 to shorten the shuttle distance for personnel, thereby improving the passage convenience of the transmission module. Therefore, the transmission module has a transmission function and improves the passage convenience, thereby improving the operation convenience of the transmission module.

[0042] In some embodiments, refer to Figure 1 and Figure 4The transmission module also includes a micro switch 50 and a controller (not shown). The micro switch 50 is located on the top of the second support 12. When in the closed state, the second connecting rod 22 abuts against the micro switch 50 to conduct the internal circuit of the micro switch 50. Specifically, the second connecting rod 22 causes the drive rod 51 of the micro switch 50 to move downward to conduct the circuit of the micro switch 50. The micro switch 50 is an open component, so its specific structure will not be described in detail. When in the open state, the second connecting rod 22 moves away from the micro switch 50, and the drive rod 51 moves upward to its original position, causing the internal circuit of the micro switch 50 to disconnect. The controller outputs a first signal based on the on signal of the micro switch 50 and a second signal based on the off signal of the micro switch 50. The drive assembly operates according to the first signal and stops operating according to the second signal. Specifically, when the micro switch 50 is off, the drive assembly stops driving the roller 23 to rotate, thus preventing material from being fed into the conveyor module. When the micro switch 50 is on, the drive assembly drives the roller 23 to rotate, enabling the conveyor module to transport materials. Adding a micro switch 50 and a controller to the conveyor module improves automation.

[0043] In some embodiments, refer to Figure 1 and Figure 2 There is a gap between the opposite ends of the second connecting rod 22 and the first connecting rod 21. The transmission module also includes two rotating components 60. One rotating component 60 is located away from the second support 12 and on one side of a nitrogen spring 40. The rotating component 60 includes a first rotating shaft 61 and a rotating rod 62. The rotating rod 62 is located away from the roller and on the same side of the first connecting rod 21 and the second connecting rod 22. The first rotating shaft 61 protrudes from the first connecting rod 21 along the second direction Y and passes through one end of the rotating rod 62. The rotating rod 62 can rotate around the first rotating shaft 61. The other end of the rotating rod 62 is fixed to the second connecting rod 22. Thus, the second connecting rod 22 is rotatably connected to the first connecting rod 21 through the rotating component 60. The rotating component 60 of this application has a simple structure. In addition, the second connecting rod 22 and the first connecting rod 21 are spaced apart, which can reduce the resistance during rotation.

[0044] In some embodiments, refer to Figures 1 to 3 The rotating assembly 60 also includes a limiting member 63, which is located on one side of the first rotating shaft 61 relative to the first support 11. When in the open state, the end of the rotating rod 62 connected to the first rotating shaft 61 abuts against the end face of the limiting member 63 away from the second support 12 to stabilize the included angle between the first connecting rod 21 and the second connecting rod 22. For example, the first connecting rod 21 and the second connecting rod 22 can form a right angle. Therefore, the limiting member 63 helps to improve the obstacle avoidance stability of the transmission module.

[0045] In some embodiments, continue to refer to Figures 1 to 3The limiting member 63 has a first end face 631, a second end face 632 and an inclined surface 633. The first end face 631 is disposed away from the second support 12, the second end face 632 is perpendicular to the first end face 631 and disposed relative to the first rotating shaft 61, and the inclined surface 633 connects the first end face 631 and the second end face 632. The rotating rod 62 has a third end face 621, which includes a first region 6211, an arcuate region 6212, an inclined region 6213, and a second region 6214 connected in sequence. In the open state, the first region 6211 is attached to the first end face 631, and the arcuate region 6212 is spaced apart from the second end face 632. The second region 6214 is parallel to the first region 6211 and closer to the second connecting rod 22. The arcuate region 6212 is curved away from the limiting member 63. The included angle between the inclined region 6213 and the second region 6214 is equal to the included angle between the inclined surface 633 and the first end face 631. The shapes of the limiting member 63 and the rotating rod 62 are designed so that during rotation, only the first region 6211 can be attached to the first end face 631 for limiting, while other regions do not contact the limiting member 63 to reduce rotational friction of the rotating rod 62.

[0046] In some embodiments, refer to Figure 1 and Figure 2 The nitrogen spring 40 is located on the same side of the first connecting rod 21 and the second connecting rod 22, away from the roller 23. The transmission module also includes two second rotating shafts 80 and two third rotating shafts 90. One second rotating shaft 80 passes through the mounting end of the nitrogen spring 40. The second rotating shaft 80 protrudes from the first support 11 along the second direction Y. The third rotating shaft 90 passes through the telescopic end of the nitrogen spring 40 and protrudes from the second connecting rod 22 along the second direction Y. For example, mounting holes can be provided on both the second connecting rod 22 and the first support 11 to fix the third rotating shaft 90 and the second rotating shaft 80. The nitrogen spring 40 can rotate around the third rotating shaft 90 and the second rotating shaft 80, thereby rotatably connecting the nitrogen spring 40 to the second connecting rod 22 and rotatably connecting it to the first support 11.

[0047] In some embodiments, refer to Figure 1 The transmission module also includes two handles 70. One handle 70 is located at the end of the second link 22 away from the first link 21. The handle 70 is positioned away from the second support 12 or away from the roller 23. The connection point between the handle 70 and the second link 22 is further away from the first link 21 than the connection point between the nitrogen spring 40 and the second link 22. The position of the handle 70 helps reduce the lifting effort required by the user.

[0048] In some embodiments, continue to refer to Figure 1The handle 70 is positioned away from the second support 12. The handle 70 includes two first grip portions 71 and a second grip portion 72. Exemplarily, the first grip portions 71 and 72 can be integrally formed. The two first grip portions 71 are spaced apart along the arrangement direction of the rollers 23 connected to the second connecting rod 22. The second grip portion 72, together with the two first grip portions 71 and the second connecting rod 22, forms a cavity 701. Exemplarily, a fixing hole can be provided in the second connecting rod 22, and the end of the first grip portion 71 away from the second grip portion 72 can be fixed in the fixing hole. In practical use, the user's fingers can pass through the cavity 701 to grip the second grip portion 72. The shape of the handle 70 facilitates the lifting operation of the transmission module. Furthermore, the fact that the handle 70 is positioned away from the second support 12 helps to extend the service life of the handle 70.

[0049] In some embodiments, the drive assembly includes a drive member 31 and a transmission ring (not shown). The drive member 31 is fixed to the first support 11 or the first connecting rod 21. In this embodiment, the drive member 31 is fixed to the first connecting rod 21. For example, the drive member 31 can be a motor. The transmission ring is drivenly connected to the drive member 31 and each roller 23. In this embodiment, the transmission ring can be a transmission chain. Correspondingly, the output shaft of the drive member 31 and the end of the multiple rollers 23 adjacent to the drive member 31 can be connected to gears. The drive of the multiple rollers 23 is realized through the meshing of the transmission chain and the gears. In another embodiment, the transmission ring can be a conveyor belt.

[0050] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
