Description

Technical Field

[0001] This utility model relates to the field of safety rope technology, specifically to a safety rope suspension device for power transmission and transformation projects. Background Technology

[0002] In high-altitude operations in power transmission and transformation projects, which often involve complex and dangerous environments such as high altitude and high voltage, workers need to use safety ropes and other protective devices to ensure their own safety when carrying out line maintenance.

[0003] The existing safety ropes are directly attached to the cable with a hook at one end and directly tied to the user's body at the other end. When a worker falls accidentally, the safety rope directly bears the impact of the worker's weight. The huge impact force is instantly transmitted to the worker's body, which can easily cause injury. In addition, the safety rope directly connects the worker to the cable through the hook, which causes the worker to sway up and down too much and for too long when falling, making it difficult to stabilize quickly. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a safety rope suspension device for power transmission and transformation projects, thereby solving the problems mentioned in the background art.

[0005] To achieve this objective, the present invention adopts the following technical solution: A safety rope suspension device for power transmission and transformation projects includes a hook lock and an air buffer sleeve. The air buffer sleeve is located at the bottom of the hook lock, and a positioning hole is opened at the center of the bottom of the hook lock. A vertically upward positioning shaft is fixedly welded to the top outer wall of the air buffer sleeve. The outer wall of the positioning shaft is rotatably connected to the inner wall of the positioning hole. A piston plate is slidably connected to the inner wall of the air buffer sleeve. A rubber ring is sleeved on the outer wall of the piston plate, and the outer wall of the rubber ring is interference-fitted with the inner wall of the air buffer sleeve. A vertically downward tension rod is fixedly located at the center of the bottom of the piston plate, and a hanging ring is fixedly located at one end of the bottom of the tension rod. An air inlet sleeve is fixedly located on one side of the top outer wall of the air buffer sleeve through an opening.

[0006] As a preferred embodiment of the safety rope suspension device for power transmission and transformation projects, the outer wall of the air inlet sleeve is provided with an adjustment knob.

[0007] As a preferred embodiment of the safety rope suspension device for power transmission and transformation projects, a return spring is sleeved on the outer wall of the tension rod, the tension rod is located inside the air buffer sleeve, and the top end of the return spring contacts the bottom outer wall of the piston plate.

[0008] As a preferred embodiment of the safety rope suspension device for power transmission and transformation projects, a limiting plate is fixedly provided on the outer wall of the tension rod, the straight-line distance between the piston plate and the limiting plate is less than the height of the air buffer sleeve, and the limiting plate is located outside the air buffer sleeve.

[0009] As a preferred embodiment of the safety rope suspension device for power transmission and transformation projects, the top two outer walls of the hook lock have rotating holes, and the inner walls of the two rotating holes are movably connected to a rotating shaft through bearings, with pulleys installed on the rotating shaft.

[0010] As a preferred embodiment of the safety rope suspension device for power transmission and transformation projects, the bottom side outer wall of the hook lock includes a notch, and the hook lock is movably connected to the locking tongue on the top side of the notch via a torsion spring.

[0011] As a preferred embodiment of the safety rope suspension device for power transmission and transformation projects, the inner wall of the air buffer sleeve is coated with lubricant.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model relates to a safety rope suspension device for power transmission and transformation projects. A safety rope is secured to a worker via a hanging ring. The other end of the safety rope is attached to the worker's body. In the event of an accidental fall, the worker, secured to the safety rope, moves a tension rod downwards via the hanging ring. The tension rod causes a piston plate to slide within an air buffer sleeve, utilizing the air inside the sleeve to create a buffer. The piston plate's downward sliding within the air buffer sleeve further reduces the impact on the worker, preventing injury from the fall. It also reduces the worker's vertical movement under the influence of the safety rope, allowing the worker to quickly stabilize. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0022] like Figures 1 to 3As shown, this embodiment provides a safety rope suspension device for power transmission and transformation projects, including a hook lock 1 and an air buffer sleeve 4. The air buffer sleeve 4 is installed at the bottom of the hook lock 1. The top outer wall of the air buffer sleeve 4 is fixed by a vertically upward positioning shaft 3 welded to it. The positioning shaft 3 is inserted into a positioning hole 2 opened at the center of the bottom of the hook lock 1. The outer wall of the positioning shaft 3 and the inner wall of the positioning hole 2 form a rotatable connection. The air buffer sleeve 4 rotates relative to the hook lock 1 at a certain angle.

[0023] Meanwhile, a piston plate 5 is provided inside the air buffer sleeve 4. The rubber ring 6 fitted on the outer wall of the piston plate 5 is interference-fitted with the inner wall of the air buffer sleeve 4, thereby ensuring the sealing of the piston plate 5 when it slides inside the air buffer sleeve 4. At the same time, due to the elasticity of the rubber ring 6, the piston plate 5 can slide inside the air buffer sleeve 4. A vertically downward tension rod 7 is fixedly installed at the center of the bottom of the piston plate 5. A hanging ring 9 is fixed at one end of the bottom of the tension rod 7, and a safety rope can be hung on this hanging ring 9. A return spring 12 is fitted on the outer wall of the tension rod 7, and the tension rod 7 is located inside the air buffer sleeve 4. The top end of the return spring 12 is in contact with the bottom outer wall of the piston plate 5. When the tension rod 7 is subjected to a downward pulling force, the piston plate 5 moves downward to compress the return spring 12. When the pulling force disappears, the return spring 12 pushes the piston plate 5 to return to its original position. Example

[0024] Based on Embodiment 1, in this embodiment, an air inlet sleeve 10 is fixedly installed on the outer wall of the top side of the air buffer sleeve 4 through an opening. An adjustment knob 11 is provided on the outer wall of the air inlet sleeve 10. By rotating the adjustment knob 11, the air intake of the air inlet sleeve 10 can be adjusted, thereby controlling the buffering effect of the air inside the air buffer sleeve 4.

[0025] Meanwhile, a limiting plate 8 is fixedly installed on the outer wall of the tension rod 7, and the straight distance between the piston plate 5 and the limiting plate 8 is less than the height of the air buffer sleeve 4. The limiting plate 8 is located below the air buffer sleeve 4 to prevent the piston plate 5 from being completely pushed into the top of the air buffer sleeve 4 and to prevent the air inlet end of the air inlet sleeve 10 from being blocked. The inner wall of the air buffer sleeve 4 is coated with lubricant. The lubricant can not only prevent the piston plate 5 from sliding and getting stuck inside the air buffer sleeve 4, but also prevent the inner wall of the air buffer sleeve 4 from rusting. Example

[0026] Based on Embodiment 1, the hook lock 1 in this embodiment has a notch on one side of its bottom outer wall. The hook lock 1 is connected to the locking tongue 16 by a torsion spring on the top side of the notch. Pressing the locking tongue 16 opens the notch, and the cable is hung into the hook lock 1 through the notch. The locking tongue 16 is reset under the action of the torsion spring, locking the notch and preventing the hook lock 1 from falling off the cable.

[0027] Meanwhile, the top two outer walls of the hook lock 1 have rotating holes 13. The inner walls of the two rotating holes 13 are connected to the rotating shaft 14 by bearings, and the pulley 15 is installed on the rotating shaft 14. When the worker needs to move, the cable is carried on the pulley 15. The pulley 15 can reduce the friction between the cable and the hook lock 1, and help the worker move on the cable.

[0028] Working principle and usage process of this utility model: Refer to the instruction manual appendix Figure 1-3 When using the safety rope suspension device for power transmission and transformation projects, first hang the hook lock 1 on the cable in the power transmission and transformation project. Then press the locking tongue 16 located on the top side of the notch of the hook lock 1, which is connected by a torsion spring to open the notch. After the hook lock 1 is accurately hung, release the locking tongue 16. The locking tongue 16 will reset and lock the notch under the action of the torsion spring. Next, according to actual work requirements, the air intake speed of the air intake sleeve 10 is adjusted by rotating the adjustment knob 11 on the outer wall of the air intake sleeve 10 on one side of the top of the air buffer sleeve 4, thereby controlling the buffering effect of the air inside the air buffer sleeve 4. Afterwards, one end of the safety rope is tied to the hanging ring 9 at the end of the tension rod 7 at the bottom of the air buffer sleeve 4. During the operation, when the worker falls accidentally, the safety rope will take effect. The safety rope will drive the tension rod 7 to move downward. The tension rod 7 will drive the piston plate 5 to slide inside the air buffer sleeve 4, compressing the return spring 12. At the same time, the air inside the air buffer sleeve 4 will act as a buffer, reducing the impact force on the worker and preventing the worker from being subjected to the impact force generated when falling. This will reduce the worker's vertical range under the action of the safety rope, allowing the worker to stabilize quickly. After the worker returns to a safe position under the protection of the safety rope, the force on the safety rope will end. At this time, the return spring 12 will push the piston plate 5 and the tension rod 7 to return to their original positions. When the worker moves on the cable, the pulley 15 mounted on the top pivot 14 of the hook lock 1 rolls along the cable, making it convenient for the operator to work on the cable.

[0029] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
