Technical Field
[0001] The utility model relates to the field of flexible guide rails, in particular to a flexible guide rail for a steel strand type anti-falling device. Background Art
[0002] Flexible guide rails are used for the safety of workers climbing up to high altitudes. They slide quickly within a limited distance to lock the falling. That is, if the descending speed of a person or equipment exceeds the rated speed, the fall arrester will immediately lock it on the guide rail to stop the person or equipment from falling further. It is generally used for power workers to climb high-altitude signal towers for protection;
[0003] The existing flexible guide rail fall arrester has a protection line generally made of wire rope and steel rope. The friction between the wire rope and the fall arrester wheel in the fall arrester is used to form the main force contact to protect the operator in the high-altitude operation. After long-term use of the wire rope, its surface will be seriously damaged due to its material, and its service life is short. The load-bearing strength of the wire rope is also insufficient. However, when the steel rope is used, when the operator climbs up, the fall arrester and the steel rope are in a semi-tensioned state because the surface of the steel rope is relatively smooth. When the fall arrester and the steel rope are not locked, there is a sense of entanglement between them. Because the fall arrester needs to be driven to move together when climbing, the operator's load is high.
[0004] Therefore, it is necessary to propose a flexible guide rail for a steel strand type fall prevention device to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a flexible guide rail for a steel strand type fall arrester, so as to solve the problem that the engagement between the fall arrester and the steel rope is tight, the fall arrester and the steel rope are in a semi-tensioned state, and there is a sense of entanglement between the fall arrester and the steel rope when they are not locked. When climbing, the fall arrester needs to be moved together, which leads to a high load on the operator.
[0006] To achieve the above object, the utility model provides the following technical solution: a flexible guide rail for a steel strand type anti-falling device, comprising a guide rail body, the guide rail body comprising an anti-falling sleeve and a balance plate fixedly arranged at one end of the anti-falling sleeve, an anti-falling steel cable movably arranged inside the anti-falling sleeve, and a balance steel cable slidably arranged inside the balance plate;

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] The utility model provides Figure 1 - Figure 6 A flexible guide rail for a stranded wire type anti-falling device shown in the figure comprises a guide rail body, the guide rail body comprises an anti-falling sleeve 3 and a balancing plate 4 fixedly arranged at one end of the anti-falling sleeve 3, an anti-falling steel cable 1 is movably arranged inside the anti-falling sleeve 3, a balancing steel cable 2 is slidably arranged inside the balancing plate 4, and a circular hole for the anti-falling steel cable 1 and the balancing steel cable 2 to pass through one end of the anti-falling sleeve 3 and the balancing plate 4 is penetrated to ensure that the operator can drive the anti-falling sleeve 3 and the balancing plate 4 to pass through the anti-falling steel cable 1 and the balancing steel cable 2 smoothly, and the anti-falling steel cable 1 and the balancing steel cable 2 are commonly used in the prior art and will not be described in detail here;
[0027] And by restraining each other through the anti-falling steel cable 1 and the balancing steel cable 2, and by connecting the balancing plate 4, the stability of the anti-falling device 7 can be increased;
[0028] A guide groove 5 is provided on the inner side of the anti-fall sleeve 3, and a conical slot 6 is symmetrically provided on the inner side of the anti-fall sleeve 3. The conical slot 6 and the circular hole at the anti-fall sleeve 3 are connected. Two blocks 7 are slidably provided on the inner side of the guide groove 5. A plurality of vertical slots 9 are penetrated through the upper ends of the two blocks 7. A plurality of splitting slots 8 are provided on the inner side of the blocks 7. The splitting slot 8 splits a single vertical slot 9 into a plurality of vertical slots 9 to approach the anti-fall steel cable 1. The guide groove 5 and the conical slot 6 are connected.
[0029] A weight-reducing hole 10 is provided through one end of the block 7, and two supporting ribs 11 are fixedly provided on the inner wall of the weight-reducing hole 10. The weight-reducing hole 10 and the supporting ribs 11 are arranged in a triangle. Based on the principle of better stability of the triangle, the weight-reducing hole 10 and the supporting ribs 11 are arranged to minimize the load on climbers and ensure the strength of the block 7 itself.
[0030] The inner side of the vertical groove 9 abuts against the outer line of the anti-falling steel cable 1. The anti-falling steel cable 1 is formed by a plurality of separate steel ropes arranged in a ring, and the diameter of the vertical groove 9 is smaller than the diameter of the steel rope, so that the vertical groove 9 can lock the steel rope.
[0031] A connecting ring is fixedly provided at one end of the balance board 4, and the connection of the belt and the cable of the climber is ensured by the setting of the connecting ring. The connecting ring is a commonly used device for climbing, and will not be described in detail here.
[0032] Working principle: The operator first uses the drone and gravity self-locking mechanism to fix the upper ends of the anti-falling steel cable 1 and the balancing steel cable 2, and then installs the cable, and then fixes the lower ends of the anti-falling steel cable 1 and the balancing steel cable 2 with a locking and fixing device. The gravity self-locking structure and the locking and fixing device are common existing technologies in high-altitude operations, and will not be described in detail here. After the two ends of the anti-falling steel cable 1 and the balancing steel cable 2 are installed and fixed;
[0033] The operator puts on the whole body safety belt and the like, and then connects the buckle on the cable and the connecting ring on the anti-fall sleeve 3. After the connection is completed, the climbing operation is carried out. At this time, the clamping block 7 is at the bottom end of the inner side of the anti-fall sleeve 3 due to gravity. At this time, the clamping block 7 does not rigidly contact the anti-fall steel cable 1, so that the climber does not feel the sense of worry, but can only feel the weight of the anti-fall sleeve 3 and other components, which is convenient for completing the climbing and saving physical strength to the greatest extent;
[0034] When the anti-fall sleeve 3 descends at a faster speed, the card block 7 moves upward in the guide groove 5 of the anti-fall sleeve 3, so that the two card blocks 7 and the conical card groove 6 are squeezed against each other, so that the card block 7 squeezes the anti-fall steel cable 1, so that the card block 7 initially locks the anti-fall steel cable 1, and then contacts the surface texture of the anti-fall steel cable 1 through the vertical groove 9, and then uses the rotation direction of the surface texture of the anti-fall steel cable 1 to perform a secondary locking action on it to complete the anti-fall purpose, and the card block 7 then transfers the torsional force to the anti-fall sleeve 3 through the guide groove 5, so that the anti-fall sleeve 3 prevents the card block 7 from twisting when locking the anti-fall steel cable 1 through the setting of the balance plate 4 and the balance steel cable 2, and splits the single vertical groove 9 into multiple vertical grooves 9 by the splitting groove 8, so as to ensure that the surface texture of the anti-fall steel cable 1 can be stuck in the vertical groove 9, while increasing its contact effect, and through the setting of the two card blocks 7, only one of the card blocks 7 needs to work normally, and the locking work can be performed to complete the anti-fall protection.
