Description

Technical Field

[0001] This utility model relates to the field of safety emergency protection rope technology, specifically an emergency protection rope for road and bridge construction safety. Background Technology

[0002] A safety rope is a protective device used to protect construction workers from fall injuries when working at heights. In road and bridge construction, the use of safety ropes is particularly important due to the complex working environment and the inherent risks of working at heights. Its main function is to connect construction workers to safety harnesses, ensuring their safety while working at heights. Depending on the actual conditions of the construction site, an appropriate type of safety rope must be selected, such as steel wire rope, fiber rope, or synthetic fiber rope, to adapt to different load-bearing capacities and stress requirements.

[0003] According to a public notice regarding an emergency safety rope for construction (Announcement No.: CN219010794U), the aforementioned application adds multiple strands of steel wire rope inside the main rope core. The strength and tensile properties of the rope are greatly increased by the multiple wound steel wire ropes. At the same time, an elastic layer is wound around the outer surface of the main rope core. Under the action of the elastic layer, the main rope core can be stretched and the elastic layer can be deformed to buffer the tensile force on the main rope core when it is pulled instantly, thereby improving the toughness of the main rope core.

[0004] However, in actual use, the aforementioned emergency safety ropes connect the human body to safety equipment such as reinforced concrete structures in road and bridge construction, serving as the last line of safety for construction workers and ensuring their safe operation at heights. However, as the ropes are used over time, their surfaces wear down, and the resistance and friction provided by the worn surfaces are limited during tension, thus affecting the rope's effectiveness. Therefore, we propose an emergency safety rope for road and bridge construction safety. Utility Model Content

[0005] The purpose of this utility model is to provide an emergency protection rope for construction safety in road and bridge engineering, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an emergency safety rope for road and bridge construction, comprising a rope core, an outer braided rope on the outside of the rope core, and an anti-slip component on the outside of the rope core, the anti-slip component comprising:

[0007] A connecting sleeve is fitted onto the outside of the rope core. A spiral isolation strip is fixedly connected to the arc-shaped outer wall of the connecting sleeve. The number of spiral isolation strips is set to six, and the six sets of spiral isolation strips are evenly distributed in a circumferential array on the arc-shaped outer wall of the connecting sleeve. An installation cavity is formed in the gap between two adjacent sets of spiral isolation strips. A convex ball is fixedly installed on the side surface of the spiral isolation strip.

[0008] A collar is fixedly installed inside the connecting sleeve. An annular groove is provided on the arc-shaped outer wall of the collar, and a cone head is fixedly installed on the arc-shaped inner surface of the collar.

[0009] Preferably, the spiral isolation strip is spirally arranged, and the number of outer braided ropes is set to six, with the six sets of outer braided ropes respectively arranged in the mounting cavity formed between the six sets of spiral isolation strips, so that the outer surface of the emergency protective rope is spirally arranged as a whole, which can play a good anti-slip role.

[0010] Preferably, the spiral isolation strip has an annular cavity at its center, and the collar is disposed in the annular cavity, so that the spiral isolation strip on the outside of the rope core has a cavity at certain intervals. This allows the emergency protection rope to achieve locking and anti-slip by simply relying on the deformation of the cavity on its outer surface when it is wound or tied.

[0011] Preferably, the number of convex balls is set to several groups, and the several groups of convex balls are evenly distributed on the side of the spiral isolation strip, so that the convex balls can decelerate and limit the outer braided rope when it tends to slip in the installation cavity.

[0012] Preferably, the cones are arranged in multiple sets, and the multiple sets of cones are evenly distributed in a spiral array on the arc-shaped inner surface of the collar. The cones pass through the connecting sleeve and are squeezed into contact with the rope core.

[0013] Preferably, the number of annular grooves is set to multiple sets, and the multiple sets of annular grooves are evenly distributed in a linear array on the arc-shaped outer surface of the collar.

[0014] Preferably, the connecting sleeve has a circular hole at its center that matches the outer diameter of the rope core, and the connecting sleeve is fitted onto the outside of the rope core during assembly.

[0015] Compared with the prior art, this utility model provides an emergency safety rope for road and bridge construction, which has the following advantages:

[0016] 1. The emergency protection rope used for construction safety of this road and bridge project has a pre-reserved cavity between its spiral isolation strips during the locking connection process. When it is wrapped or tied, it can achieve locking and anti-slip by relying solely on the deformation of the cavity on its outer surface. This avoids the problem of the safety factor decreasing due to dragging or wear over time during use, and ensures the safe use effect of the emergency protection rope.

[0017] 2. The emergency safety rope used in the construction of this bridge and road project uses convex balls and annular grooves to slow down and limit the outer braided rope when it tends to slip in the installation cavity, thus preventing the outer braided rope from detaching from the installation cavity and affecting the stability of the emergency safety rope.

[0022] like Figures 1-3 As shown, this utility model provides a technical solution: an emergency protection rope for construction safety of road and bridge engineering, including a rope core 1, an outer braided rope 2 on the outside of the rope core 1, and an anti-slip component 3 on the outside of the rope core 1. The anti-slip component 3 includes a connecting sleeve 31, a spiral isolation strip 32, an installation cavity 33, a convex ball 34, a collar 35, an annular groove 36, and a cone head 37.

[0023] In one embodiment of this utility model, a connecting sleeve 31 is sleeved on the outside of the rope core 1. A spiral isolation strip 32 is fixedly connected to the arc-shaped outer wall of the connecting sleeve 31. The number of spiral isolation strips 32 is set to six, and the six sets of spiral isolation strips 32 are evenly distributed in a circumferential array on the arc-shaped outer wall of the connecting sleeve 31. An installation cavity 33 is formed in the gap between two adjacent sets of spiral isolation strips 32. A convex ball 34 is fixedly installed on the side surface of the spiral isolation strip 32. A collar 35 is fixedly installed inside the connecting sleeve 31. An annular groove 36 is opened on the arc-shaped outer wall of the collar 35. A cone head 37 is fixedly installed on the arc-shaped inner surface of the collar 35.

[0024] Furthermore, the rope core 1 is made of synthetic fiber material and is solid. At the same time, the center of the connecting sleeve 31 has a circular hole that matches the outer diameter of the rope core 1. During assembly, the connecting sleeve 31 is fitted onto the outside of the rope core 1. In addition, the spiral isolation strip 32 is spirally arranged, and there are six sets of outer braided ropes 2. The six sets of outer braided ropes 2 are respectively arranged in the mounting cavity 33 formed between the six sets of spiral isolation strips 32, so that the outer surface of the emergency protective rope is spirally arranged as a whole, which can achieve a good anti-slip effect.

[0025] In addition, the end surface of the spiral isolation strip 32 is in contact with the arc-shaped outer surface of the two adjacent sets of outer braided ropes 2, making the surface of the resulting emergency protection rope more compact. The outer braided ropes 2 and the rope core 1 can withstand stronger tension. At the same time, an annular cavity is opened at the center of the spiral isolation strip 32, and the collar 35 is set in the annular cavity. This makes the spiral isolation strip 32 on the outside of the rope core 1 have a cavity at certain intervals. This allows the emergency protection rope to achieve locking and anti-slip by relying solely on the deformation of its outer surface cavity when it is wound or tied. This avoids the problem of reduced safety factor due to dragging or wear over time during use, ensuring the safe use effect of the emergency protection rope.

[0026] Meanwhile, the number of convex balls 34 is set in several groups, and the several groups of convex balls 34 are evenly distributed on the side of the spiral isolation strip 32, so that the convex balls 34 can decelerate and limit the outer braided rope 2 when it tends to slip in the mounting cavity 33, and prevent the outer braided rope 2 from detaching in the mounting cavity 33.

[0027] In this embodiment of the invention, multiple sets of annular grooves 36 are arranged in a linear array and evenly distributed on the arc-shaped outer surface of the collar 35. At the same time, multiple sets of cones 37 are arranged in a spiral array and evenly distributed on the arc-shaped inner surface of the collar 35. Specifically, the cones 37 pass through the connecting sleeve 31 and press against the rope core 1, further ensuring the connection stability between the connecting sleeve 31, the collar 35, the spiral isolation strip 32, and the rope core 1. This prevents the emergency protection rope from slipping or becoming tangled during use, ensuring the safety and service life of the emergency protection rope.

[0028] Specifically, the annular groove 36 allows the outer braided rope 2 to fit more tightly against the surface of the annular groove 36 during the tightening process. The lateral restriction of the annular groove 36 prevents the outer braided rope 2 from excessively displacing within the mounting cavity 33, thus ensuring the stability of the emergency protection rope.

[0029] In this invention, one end of the emergency protection rope is connected to a safety buckle, which is then fastened to the safety clothing of the construction workers. The other end of the emergency protection rope is then locked to the reinforced concrete structure of the bridge or road construction project. This ensures the safety of the workers during the construction. Simultaneously, during the locking process, the cavities between the spiral isolation strips 32 allow for locking and anti-slip by simply deforming the outer surface of the rope during winding or tightening. This prevents the safety factor from decreasing due to dragging or wear over time, ensuring the safe use of the emergency protection rope.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
