DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] See attached Figure 1 To the attached Figure 7 As shown, this embodiment provides a bracket conveying structure 100 on a transmission line, which includes a bracket 1, multiple groups of conveying roller assemblies 2, a control device and a sensor device 3. The control device is connected to the conveying roller assembly 2 and is used to control the rotation state of the conveying roller assembly 2.

[0025] Refer to the attached Figure 1 and attached Figure 2As shown, in this embodiment, multiple sets of conveyor roller assemblies 2 are evenly spaced along the length of the bracket 1. Each set of conveyor roller assemblies 2 includes a pair of support frames 22, conveyor rollers 21, and an elastic lifting device 23. The pair of support frames 22 are mounted on the bracket 1 in a left-right opposing relationship. The bottom ends of the support frames 22 are vertically fixedly mounted on the outer edge of the top surface of the bracket 1. The top ends of the support frames 22 are mounted in grooves 221, and the ends of the conveyor rollers 21 are rotatably mounted within these grooves 221.

[0026] The elastic lifting device 23 is disposed at a lower side of one end of the conveying roller 21 . The elastic lifting device 23 includes a lifting shaft 232 , a spring 233 , an upper connecting ring 235 , a lower connecting ring 234 and a mounting seat 231 .

[0027] Mounting base 231 defines a cavity for accommodating lifting shaft 232. Mounting base 231 is fixedly mounted on the outside of support frame 22. Mounting base 231 has upper and lower mounting holes formed on its top and bottom surfaces. For ease of description, the mounting holes at the top and bottom of mounting base 231 are referred to as first through-holes and second through-holes, respectively. The first through-hole can be formed vertically through the top surface of mounting base 231, and the second through-hole can be formed vertically through the bottom surface of mounting base 231.

[0028] The lifting shaft 232 may vertically pass through the first through hole, and the upper portion of the lifting shaft 232 may extend outward through the first through hole 236 ; in addition, the lifting shaft 232 may extend downward through the second through hole 237 .

[0029] An upper connecting ring 235 is fixedly mounted on the top of the lifting shaft 232. In this embodiment, the upper connecting ring 235 is annular. The rotating shaft of the conveyor roller 21 passes through the upper connecting ring 235. The diameter of the upper connecting ring 235 is larger than the diameter of the first through-hole 236. Furthermore, an outwardly extending upper threaded post 2351 is formed on the outer surface of the upper connecting ring 235. Correspondingly, a threaded hole is formed at the top of the lifting shaft 232. This allows the upper connecting ring 235 to be fixedly mounted in the threaded hole at the top of the lifting shaft 232 via the upper threaded post 2351.

[0030] Similarly, the lower connecting ring 234 is annular. The steel wire 35 passes through the lower connecting ring 234. The diameter of the lower connecting ring 234 is larger than the diameter of the second through-hole 237. A lower threaded post 2341 extending outward is formed on the outer surface of the lower connecting ring 234. Correspondingly, a threaded hole is formed at the bottom end of the lifting shaft 232. Thus, the lower connecting ring 234 can be fixedly mounted in the threaded hole at the bottom end of the lifting shaft 232 via the lower threaded post 2341.

[0031] An annular stopper 238 is formed on the upper outer surface of the lifting shaft 232. To facilitate installation, an external thread is formed on the upper outer surface of the lifting shaft 232, and an internal thread is formed in the center of the stopper 238. Therefore, the stopper 238 can be fixed on the external thread through the internal thread.

[0032] Refer to the attached Figure 4 To the attached Figure 7 As shown, the spring 233 is sleeved on the outer surface of the lifting shaft 232, and the two ends of the spring 233 are respectively compressed and installed between the bottom end surface of the resisting portion 238 and the bottom inner end surface of the mounting seat 231, and the bottom end of the lifting shaft 232 is connected to the sensor device 3.

[0033] Refer to the attached Figure 3 and attached Figure 4 As shown, the sensor device 3 includes a base 31, a contact sensor 32, a guide roller 34, a magnet 33, and a steel wire 35. The base 31 is fixedly mounted on the edge of the outer end surface of the bracket 1, the contact sensor is mounted on the top surface of the base 31, and the magnet 33 is placed horizontally on the upper end of the contact sensor 32. One end of the steel wire 35 is fixedly connected to the magnet 33, and the other end of the steel wire 35 is fixedly connected to the bottom end of the lifting shaft 232. The guide roller 34 is rotatably coupled to the outer side of the bracket 1. The guide roller 34 can be located above the magnet 33. The guide roller 34 winds up the steel wire 35 and guides the steel wire 35 to move smoothly. At this time, due to the weight of the magnet 33, the tension of the steel wire 35 can be maintained.

[0034] The control device is electrically connected to the contact sensor 32 , and controls the operation of the conveying roller 21 when receiving a non-contact sensing signal from the contact sensor 32 .

[0035] To better understand the stent delivery structure 100 on the transmission line in this embodiment, the working principle thereof is briefly described below:

[0036] During operation, the conveyor roller 21 is rotatably coupled to the inner side of the upper connecting ring 235 of the lifting shaft 232. The load of the conveyor roller 21 causes the lifting shaft 232 to descend from the inner cavity of the mounting base 231, compressing the spring 233 within the mounting base 231 and placing the spring 233 in a compressed, downwardly compressed state. A magnet 33, attached to one end of a steel wire 35 that passes through the lower connecting ring 234 of the lifting shaft 232, is fixed to the contact sensor 32 by its own weight. The weight of the magnet 33 maintains the tension of the steel wire 35 in a taut state. Through contact between the magnet 33 and the contact sensor 32, a control device electrically connected to the contact sensor 32 controls the motor that drives the conveyor roller 21, causing the conveyor roller 21 to rotate.

[0037] Due to wear and damage of the conveying roller 21, if the conveying roller 21 is separated from the support frame 22, the load applied to the lifting shaft 232 will be released. As the load on the conveying roller 21 is released, the elastic restoring force of the compressed spring 233 causes the lifting shaft 232 to rise.

[0038] As the lifting shaft 232 rises, the steel wire 35 connected by the lower connecting ring 234 is pulled in the vertical direction, and the magnet 33 placed on the contact sensor 32 is detached from the top surface of the contact sensor 32, and the magnet 33 has no contact with the contact sensor 32.

[0039] Since the magnet 33 is not in contact with the contact sensor 32, the non-contact sensing signal generated by the contact sensor 32 will be received by the control device electrically connected to the contact sensor 32, and the control device will perform offline control on the motor that provides driving force for the conveying roller 21 to stop the conveying roller 21 from working.

[0040] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
