Description

Technical Field

[0001] The utility model relates to the field of safety ropes, in particular to an easily recyclable safety rope. Background Art

[0002] The safety rope is woven with synthetic fibers and is an auxiliary rope used to connect to a safety belt. It is mainly used in climbing, aerial work, escape and other occasions. When the safety rope used for climbing is descended from a high place to a low place, since the fixed position of the safety rope is at a high place, when the operator is at a low place, it is not convenient to recover the safety rope. If the safety rope is loosened and recovered when the rope is not under stress through a specific knot, there will be a great safety hazard when the personnel descend along the safety rope due to the poor stability of the knot.

[0003] Therefore, it is necessary to design a kind of easy-to-recover safety rope to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide an easily recyclable safety rope, so as to overcome the above-mentioned defects in the prior art.

[0005] According to the utility model, an easily recyclable safety rope includes a main rope body, one end of which is fixed with a hook assembly, the hook assembly includes a shell and an anchor rope, one end of the anchor rope is fixed to the shell, and the other end of the anchor rope is detachably connected to the shell in a locking manner, and a steel wire rope is arranged in the main rope body for controlling the disassembly of the end of the anchor rope.

[0006] Through the above technical solution, when climbing and rappelling, the anchor rope is wrapped around a tree or other fixed position, one end of the anchor rope is clamped in the shell, and the operator descends along the main rope body. When reaching the ground, the end of the anchor rope is controlled by the wire rope to separate from the shell, thereby separating the hook assembly from the tree or other fixed position to facilitate the recovery of the safety rope.

[0008] Through the above technical solution, the limiting sleeve can be restricted in the housing by the limiting block being clamped into the limiting groove, so that the detachable end of the anchor rope is clamped in the housing.

[0009] The utility model is further configured as follows: a plurality of cavities equidistantly distributed up and down are connected and opened in one side wall of the circular hole, the limit block is slidably connected in the cavity, and a spring is fixed between the limit block and a side wall of the cavity on the corresponding side away from the limit sleeve.

[0010] Through the above technical solution, the limiting block can be clamped in the limiting groove by utilizing the elastic force of the spring.

[0011] The utility model is further configured as follows: a through groove running through from top to bottom is opened in the limit block, a side wall of the through groove away from the limit sleeve is configured as a sliding slope, the sliding slope is inclined from top to bottom toward the side away from the limit sleeve, a push rod that can pass through the through groove is slidably connected in the shell, and an edge of a side of the upper end of the push rod away from the limit sleeve is flush with a lower edge of the sliding slope.

[0012] Through the above technical solution, the push rod slides upward to give the sliding inclined surface a thrust in the direction away from the limiting groove, so that the limiting block moves in the direction away from the limiting groove, thereby separating the limiting block from the limiting groove.

[0013] The utility model is further configured as follows: a screw is connected to the inner thread of the push rod, a winding chamber is opened in the shell and is located at the lower side of the push rod, the screw is rotatably connected to the upper side wall of the winding chamber, a winding disk is rotatably arranged in the winding chamber, the winding disk is fixed to the lower end of the screw, one end of the wire rope is wound around the outer periphery of the winding disk and fixed to its outer periphery, and a torsion spring is fixedly connected to the inner wall of the winding chamber at one end of the screw away from the shell.

[0014] Through the above technical solution, the winding disc is driven to rotate under the pulling of the wire rope, thereby causing the screw rod to rotate, and then causing the push rod to slide upward.

[0015] The utility model is further configured as follows: the main rope body includes a rope core and a coating layer coated on the outer periphery of the rope core, the rope core includes a plurality of rope strands and a support tube, the plurality of rope strands are circumferentially distributed with the support tube as the center, one end of the support tube close to the shell body passes through the outer periphery of the main rope body and is fixedly connected to the coating layer, and the steel wire rope slides in the support tube.

[0016] Through the above technical solution, the support tube facilitates the sliding of the wire rope, reduces the squeezing of the wire rope by the rope strands, and reduces the friction force on the wire rope when it slides.

[0017] The utility model is further configured as follows: the support tube is a tube formed by winding a steel wire along a spiral line.

[0018] Through the above technical solution, the support tube has good radial supporting force, ensuring that the support tube can slide in the wire rope, and at the same time the support tube can bend with the main rope body.

[0019] The utility model is further configured as follows: a fixing ring is arranged on the main rope body, a hanging ring is fixed to an end face of one side of the shell close to the main rope body, one end of the main rope body close to the shell passes through the hanging ring and then bends in half, and the fixing ring covers and fixes the folded part of the main rope body.

[0020] Through the above technical solution, the anchor rope is fixedly connected to the shell.

[0021] The utility model is further configured as follows: a sleeve is fixed to one end of the coating layer away from the shell, a cover is threadedly connected to one end of the sleeve away from the shell, and one end of the steel wire rope away from the shell is fixedly connected to the cover.

[0022] Through the above technical solution, the cover can be separated from the sleeve by rotating the cover, so that the wire rope can be pulled by pulling the cover.

[0023] The beneficial effects of the utility model are as follows: during climbing and rappelling, the anchor rope is wrapped around a tree or other position that can provide a fixation, one end of the anchor rope is clamped in the shell, and the operator rappels down along the main rope body. When reaching the ground, the wire rope is pulled to rotate the winding drum, thereby rotating the screw rod, thereby driving the push rod to move upward, and when the push rod passes through the through groove, the limit block is disengaged from the limit groove, so that the limit sleeve can be taken out of the shell, thereby realizing the separation of the anchor rope end from the shell, thereby separating the hook assembly from the tree or other fixed position, so as to facilitate the recovery of the safety rope.

[0038] An embodiment of the utility model:

[0039] Reference Figure 1-Figure 10The utility model provides an easily recyclable safety rope, including a main rope body, a hook assembly is fixed at one end of the main rope body, the hook assembly includes a shell 20 and an anchor rope 21, one end of the anchor rope 21 is fixed to the shell 20, and a hole with the same diameter as the anchor rope 21 is opened in the upper end surface of the shell 20. The end of the anchor rope 21 fixed to the shell 20 is tied with a knot and then put into the shell 20. The anchor rope 21 passes through the hole, and the connection stability between the anchor rope 21 and the shell 20 is ensured by the knot. The other end of the anchor rope 21 is detachably connected to the shell 20 in a locking manner. When the anchor rope 21 is stuck in the shell 20, the connection strength is sufficient to meet the use of climbing. A steel wire rope 15 connected to the shell 20 and capable of controlling the disassembly of the end of the anchor rope 21 is provided in the main rope body.

[0040] Reference Figure 2 , Figure 4 A circular hole is provided in the shell 20, and a limiting sleeve 22 is fixed on a detachable end of the anchor rope 21. The limiting sleeve 22 is cylindrical, and the inner diameter of the limiting sleeve 22 is consistent with the outer diameter of the anchor rope 21. The anchor rope 21 passes through the limiting sleeve 22 and is tied. The knot abuts against the end of the limiting sleeve 22, and the limiting sleeve 22 can be inserted into the circular hole. Two limiting grooves 25 are provided on the outer periphery of the limiting sleeve 22, and two limiting blocks 23 that can be inserted into the limiting grooves 25 are slidably arranged in one side wall of the circular hole.

[0041] Reference Figure 5 , Figure 6 Two cavities 28 equidistantly distributed in the upper and lower sides are connected in the wall of one side of the circular hole. The limit block 23 is slidably connected in the cavity 28. A spring 27 is fixed between the limit block 23 and the wall of the cavity 28 on the corresponding side away from the limit sleeve 22. A through groove 24 is provided in the limit block 23, and a side wall of the through groove 24 away from the limit sleeve 22 is set as a sliding slope 26. The sliding slope 26 is inclined from top to bottom toward the side away from the limit sleeve 22. A push rod 31 that can pass through the through groove 24 is slidably connected in the shell 20. The upper end of the push rod 31 is chamfered, and the edge of the side of the upper end of the push rod 31 away from the limit sleeve 22 is flush with the lower edge of the sliding slope 26.

[0042] Reference Figure 6 , Figure 7 The push rod 31 is threadedly connected to a screw rod 32, and a winding chamber 34 is opened in the shell 20 at the lower side of the push rod 31. The screw rod 32 is rotatably connected to the upper side wall of the winding chamber 34. A winding disk 33 is rotatably arranged in the winding chamber 34, and the winding disk 33 is fixed to the lower end of the screw rod 32. One end of the wire rope 15 is wound around the outer periphery of the winding disk 33 and fixed to its outer periphery. The end of the screw rod 32 away from the shell 20 is fixedly connected to the inner wall of the winding chamber 34 with a torsion spring 30.

[0043] Reference Figure 1-Figure 10The main rope body includes a rope core and a coating layer 10 wrapped around the outer periphery of the rope core. The rope core includes a plurality of rope strands 13 and a support tube 14. The rope strands 13 and the coating layer 10 are made of ultra-high molecular weight polyethylene fiber material, which has high wear resistance and tensile strength. The plurality of rope strands 13 are circumferentially distributed around the support tube 14. An opening is opened on the outer periphery of the coating layer 10, and a circle of woven wire is sewn on the opening to reinforce the opening. The end of the support tube 14 close to the shell 20 passes through the opening on the outer periphery of the coating layer 10 and is fixed to the coating layer 10. The upper end of the support tube 14 is connected to the covering layer 10 by passing the woven thread through the steel wire and then sewn on the covering layer 10. After the main rope body is straightened, the part of the steel wire rope 15 extending out of the main rope body is in a bent and relaxed state, and the steel wire rope 15 slides in the support tube 14. The support tube 14 is a tube formed by winding the steel wire along a spiral line. A fixing ring 12 is provided on the main rope body, and a hanging ring 29 is fixed on the end face of one side of the shell 20 close to the main rope body. The end of the main rope body close to the shell 20 passes through the hanging ring 29 and then bends in half, and the fixing ring 12 covers and fixes the folded part of the main rope body.

[0044] Reference Figure 8 A sleeve 11 is fixed to one end of the coating layer 10 away from the shell 20 , a cover 16 is threadedly connected to one end of the sleeve 11 away from the shell 20 , and one end of the wire rope 15 away from the shell 20 is fixedly connected to the cover 16 .

[0045] When it is necessary to descend from a high place to a low place during the climbing process, after the anchor rope 21 passes around a tree or other fixed position, the limiting sleeve 22 is inserted into the circular hole on the upper end surface of the shell 20, and the limiting block 23 is inserted into the limiting groove 25 under the elastic force of the spring 27, thereby preventing the limiting sleeve 22 from being pulled out of the circular hole, thereby ensuring the hanging strength of the anchor rope 21.

[0046] After the operator descends along the main rope to a lower safe position, he rotates the cover 16 to disengage the cover 16 from the sleeve 11 and pulls the cover 16 downward, thereby pulling the wire rope 15 downward, causing the winding drum 33 to rotate, thereby driving the screw rod 32 to rotate, and at this time the torsion spring 30 twists and stores force.

[0047] The screw rod 32 rotates to drive the push rod 31 to move upward, so that it passes through the two limit blocks 23 one by one, so that each limit block 23 overcomes the elastic force of the spring 27 on the corresponding side and moves in the direction away from the limit groove 25 until the limit block 23 is separated from the limit groove 25. Under the weight of the main rope body and the shell 20, the anchor rope 21 is subjected to a downward pulling force, so that the limit sleeve 22 is pulled out of the circular hole on the upper end surface of the shell 20, so that the shell 20 and the anchor rope 21 are separated from the tree or other fixed position, so as to facilitate the recovery of the safety rope.

[0048] After the safety rope is recovered, the steel wire rope 15 is released, and the winding drum 33 is reversed under the torsion force of the torsion spring 30 , so that part of the steel wire rope 15 is wound onto the winding drum 33 .

[0049] In summary, after the operator descends from a high place to a low place, the safety rope can be untied from its fixed state at a high place by pulling the steel wire rope 15 at a low place, thereby separating the safety rope from the fixed position at a high place, so as to facilitate the recovery of the safety rope. The rope strands 13 and the coating layer 10 made of ultra-high molecular weight polyethylene fibers improve the wear resistance and tensile strength of the safety rope.

[0050] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
