Description

Technical Field

[0001] This utility model relates to the field of platform safety rope technology, specifically to a platform safety rope device with a winding adjustment structure. Background Technology

[0002] Platform safety ropes are devices used to ensure the safety of passengers on transportation vehicles, such as train and subway platforms. They are usually made of high-strength ropes or other materials and are installed on the edge of the platform or in dangerous areas to prevent passengers from accidentally falling or crossing the platform edge into the track area.

[0003] Common platform safety rope devices typically consist of intermittently distributed bases on both sides of the platform near the tracks, with safety ropes connecting adjacent bases to prevent passengers from accidentally falling onto the tracks. However, current platform safety rope devices use only a single rope, which is highly likely to break after prolonged use and fall onto the tracks, potentially affecting railway operations. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a platform safety rope device with a winding adjustment structure. This device provides real-time warnings about the safety rope's usage status through signals triggered by sensor contact. In the event of an accidental breakage of the safety rope, it can automatically and promptly wind up the broken rope to prevent one end from falling onto the rails.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A platform safety rope device with a winding adjustment structure is characterized by comprising two outer shells, each outer wall of which is rotatably connected to a rotating rod. Both rotating rods penetrate into the outer shells and are fixed by retainers located inside the outer shells. Each retainer is equipped with a coil spring, and a connecting rope is positioned between the two coil springs to connect the two outer shells into a single unit. When the two outer shells separate, the connecting rope extends under the action of the coil springs. A second sensor is fixedly mounted at the middle of the connecting rope, and first sensors are fixedly mounted on adjacent sides of the two outer shells at positions corresponding to the connecting rope. A signal is triggered when the first sensor contacts the second sensor.

[0007] The housing is provided with a positioning component, which is used to position the direction of the rotating rod.

[0008] The positioning assembly includes two chambers disposed within the housing. Each chamber is located at the front of the housing. Each chamber contains a ratchet, which is fixedly connected to the outer periphery of a rotating rod. A mounting bracket is fixedly connected to one side of each chamber. A rotating shaft is rotatably connected to the rear of each mounting bracket. Pawls are fixedly connected to the outer periphery of each rotating shaft. One end of a torsion spring is fixedly connected to the front and rear walls of each pawl. The other ends of multiple torsion springs are fixedly connected to the inner wall of the mounting bracket. A groove is formed on one side of the front wall of each housing. Insertion holes are provided on both sides of each groove. The front ends of each rotating shaft penetrate the groove and are connected to connecting plates. Insertion rods are fixedly connected to the upper and lower sides of the rear walls of each connecting plate.

[0009] The rear ends of both connecting plates extend into the rotating shaft and are fixedly connected to springs, and the rear ends of both springs are fixedly connected to the inner rear wall of the rotating shaft.

[0010] Both of the inner rear walls of the two rotating shafts are fixedly connected with positioning rods, and the front ends of the two positioning rods penetrate into the connecting plate.

[0011] A buzzer is fixedly connected to the housing, and the buzzer is electrically connected to the first sensor; when the first sensor contacts the second sensor to trigger a signal, the buzzer sounds an alarm.

[0012] A connecting ring is provided on the outer shell.

[0013] The advantages of this utility model are:

[0014] 1) After the connecting rope breaks, it can promptly alert the staff and reel in the connecting rope, thereby preventing the broken connecting rope from falling onto the track.

[0015] 2) It can limit the direction of the rotating rod to prevent the connecting rope from continuing to stretch under pressure when it is blocking the platform.

[0016] 3) The structure is simple and reasonable, easy to use, and suitable for promotion. Attached Figure Description

[0020] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:

[0021] like Figure 1-3 As shown in the figure, the numbers 1-21 represent: outer shell 1, buzzer 2, first sensor 3, second sensor 4, connecting rope 5, rotating rod 6, connecting plate 7, rotating shaft 8, groove 9, insertion hole 10, connecting ring 11, chamber 12, ratchet 13, pawl 14, fixing frame 15, torsion spring 16, retainer 17, coil spring 18, insertion rod 19, positioning rod 20, and spring 21.

[0022] Example: Figures 1 to 3 As shown, the platform safety rope device with a winding adjustment structure in this embodiment includes two outer shells 1. Each of the two outer shells 1 has a connecting ring 11 fixedly connected to its opposite side. The connecting ring 11 is used to connect to two adjacent safety rope bases.

[0023] Rotating rods 6 are rotatably connected to the front walls of both outer shells 1. The rear ends of the two rotating rods 6 penetrate into the outer shell 1 and are fixedly connected to retainers 17. The cross-section of the two retainers 17 is I-shaped, and the front and rear diameters of the two retainers 17 are larger than the middle diameter of the retainer 17, ensuring that the rotating rods 6 can be fixedly installed on the outer shell 1.

[0024] Both retainers 17 have one end of a coil spring 18 fixedly connected to their inner walls. The other end of one coil spring 18 is fixedly connected to one end of a connecting rope 5. The other end of the connecting rope 5 passes through the adjacent sides of the two outer shells 1 and is fixedly connected to the end of the other coil spring 18 furthest from the retainer 17, allowing the two outer shells 1 to be connected as a whole via the connecting rope 5. This structure allows for flexible adjustment of the length of the connecting rope 5 between the two outer shells 1, achieving flexible application to base connections and protection at different spacings.

[0025] A second sensor 4 is fixedly connected to the middle of the connecting rope 5. A first sensor 3 is sleeved on both sides of the middle of the connecting rope 5. The two first sensors 3 are fixedly connected to the two shells 1 on the side that are close to each other. A buzzer 2 is fixedly connected to the top wall of the two shells 1. The two buzzers 2 are electrically connected to the first sensors 3 respectively.

[0026] When installing the safety rope, the workers can pull the outer shells 1 on both sides away from each other. Since the two ends of the connecting rope 5 are wound inside the two outer shells 1 respectively, when the two outer shells 1 move away from each other, the connecting rope 5 will be stretched from both ends and extended.

[0027] Subsequently, the staff can connect the two outer shells 1 to the two adjacent bases via connecting rings 11, thereby providing barrier protection for the platform area between the two adjacent bases. At this time, since both ends of the connecting rope 5 are wound inside the outer shell 1, and both ends of the connecting rope 5 are also connected to one end of the coil spring 18, while the other end of the coil spring 18 is connected to the retainer 17 inside the outer shell 1, stretching the connecting rope 5 will pull the coil springs 18 connected on both sides respectively.

[0028] When the connecting rope 5 breaks due to prolonged use, the coil spring 18 loses pressure and resets, pulling the corresponding connecting rope 5 to rewind and reset. The broken part of the connecting rope 5 also drives the connected second sensor 4 to reset and contact the corresponding first sensor 3. When the first sensor 3 and the second sensor 4 overlap, a signal is sent to the control device to alert the staff. At the same time, the buzzer 2 receives the signal and starts to sound an alarm, thereby alerting the staff on the platform to the occurrence of the breakage. The two ends of the connecting rope 5 are respectively wound into the two outer shells 1.

[0029] like Figures 1 to 3 As shown, in this embodiment, a positioning assembly is provided on the outer shell 1, which is used to position the rotating rod 6. The positioning assembly includes two chambers 12, each located at the front of the outer shell 1. Each chamber 12 contains a ratchet 13, which is fixedly connected to the outer periphery of the rotating rod 6. A fixing frame 15 is fixedly connected to one side of each chamber 12. A rotating shaft 8 is rotatably connected to the rear of each fixing frame 15. Pads 14 are fixedly connected to the outer periphery of each rotating shaft 8. One end of a torsion spring 16 is fixedly connected to the front and rear walls of each pad 14. The other ends of multiple torsion springs 16 are fixedly connected to the inner wall of the fixing frame 15. A groove 9 is provided on one side of the front wall of each of the two outer shells 1. Both sides of the shaft 9 are provided with insertion holes 10. The front ends of the two shafts 8 pass through the grooves 9 and are provided with connecting plates 7. The rear parts of the two connecting plates 7 are square and the diameter of the rear ends of the two connecting plates 7 is larger than the diameter of the middle part. The front walls of the two connecting plates 7 are provided with protrusions for pulling. The rear ends of the two connecting plates 7 pass through the shafts 8 and are fixedly connected with springs 21. The rear ends of the two springs 21 are fixedly connected to the inner rear wall of the shafts 8. The inner rear walls of the two shafts 8 are fixedly connected with positioning rods 20. The front ends of the two positioning rods 20 pass through the connecting plates 7. The upper and lower sides of the rear walls of the two connecting plates 7 are fixedly connected with insertion rods 19.

[0030] When the lever 6 rotates, it drives the connecting ratchet 13 to rotate. Since a pawl 14 is engaged on one side of the ratchet 13, the ratchet 13 will push the pawl 14 to rotate when it rotates clockwise. When the pawl 14 rotates, it will pull the torsion spring 16 connected to the front and rear sides. Under the action of the torsion spring 16, the pawl 14 can be pulled to abut against the ratchet 13, thus ensuring that the pawl 14 and the ratchet 13 are always in contact. When the ratchet 13 rotates counterclockwise, it will engage with the pawl 14, thus limiting the ratchet 13 so that it can only rotate clockwise and cannot reverse. When it is necessary for the ratchet 13 to rotate counterclockwise, pulling the connecting plate 7 outward will cause the connected insert 19 to be pulled out of the groove 9. Then, the connecting plate 7 can be rotated counterclockwise to drive the connected rotating shaft 8 to rotate counterclockwise. When the rotating shaft 8 rotates counterclockwise, it will drive the connected pawl 14 to rotate counterclockwise, thereby causing the pawl 14 to disengage from the ratchet 13. When the connecting plate 7 rotates, it will also drive the connected insert 19 to rotate. When the insert 19 rotates to the insertion hole 10, the connecting plate 7 will be pulled outward to stretch the connected spring 21. Therefore, under the action of the spring 21, the connecting plate 7 can be pulled back to its original position and the insert 19 can be inserted into the insertion hole 10 for positioning. At the same time, under the action of the positioning rod 20, the spring 21 can be limited to prevent the spring 21 from bending when compressed, thereby allowing the pawl 14 to disengage from the ratchet 13. At this time, the ratchet 13 can rotate clockwise or counterclockwise.

[0031] Therefore, when the operator needs to stretch the connecting rope 5, the operator can first pull the connecting plate 7 to extend it and rotate the connecting plate 7 counterclockwise. When the connecting plate 7 drives the insertion rod 19 to rotate to the insertion hole 10, the insertion rod 19 is inserted into the insertion hole 10 for positioning, which cancels the limiting of the pawl 14 and the ratchet 13. At this time, the ratchet 13 and the rotating rod 6 can rotate counterclockwise, thereby stretching the winding of the connecting rope 5 in the corresponding outer shell 1. When the connecting rope 5 is stretched to an appropriate length and both outer shells 1 are connected to the adjacent base, the operator can pull the connecting plate 7 again and rotate it clockwise, so that the connecting plate 7 and the insertion rod 19 are engaged in the groove 9. At this time, the pawl 14 will engage with the ratchet 13 again, so that the ratchet 13 can maintain normal clockwise rotation and winding of the connecting rope 5, while limiting the counterclockwise rotation of the rotating rod 6. This can prevent the connecting rope 5 from continuing to stretch and losing its blocking effect when it is under pressure during the blocking and protection process.

[0032] When applied, this embodiment follows the following working principle:

[0033] By pulling the connecting plate 7 outward and rotating it, the rotating shaft 8 and the pawl 14 connected to the rotating shaft 8 can be driven to rotate, thereby moving the pawl 14 away from the ratchet 13. Then, the insertion rod 19 is inserted into the insertion hole 10 and limited. At this time, the operator can pull the two outer shells 1 away from each other. When the two outer shells 1 are away from each other, the connecting rope 5 will be stretched from both ends. Then, the two outer shells 1 are fixed to two adjacent bases respectively. By pulling the insertion rod 19 out of the insertion hole 10 and rotating the connecting plate 7 in the opposite direction to reset it, the pawl is moved away from the ratchet 14. 14 is locked onto ratchet 13 again for limiting, thereby blocking the area between two adjacent bases. Since the connecting rope 5 will pull the coil spring 18 when it is stretched, the corresponding connecting rope 5 can be pulled to rewind and reset under the action of coil spring 18 after the connecting rope 5 is broken, thereby preventing the broken connecting rope 5 from falling into the track. The broken connecting rope 5 on one side will drive the second sensor 4 to reset. When the second sensor 4 contacts the first sensor 3, it will send a signal to remind the staff that the connecting rope 5 is broken.

[0034] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
