Description
Technical Field
[0001] The utility model belongs to the technical field of electric power safety equipment, and in particular relates to an iron tower anti-falling device. Background Art
[0002] The tower fall arrester is a protective device used to keep tower operators suspended in the air when they fall during climbing or moving operations. The fall arrester usually includes a track and a fall arrester installed on the track. The operator is connected to the fall arrester through a safety rope. When the operator falls, the fall arrester will automatically lock onto the track to prevent the operator from falling to the ground. When the fall arrester is installed on the track, the bottom end of the track is usually inserted into the fall arrester. In order to prevent the fall arrester from leaving the track before climbing, a baffle is usually hinged at the bottom end of the track. The fall arrester can be limited to the baffle. To prevent the baffle from being lost, the operator usually removes the baffle from the track and keeps it after climbing. The baffle needs to be installed and removed during each operation, and the complicated operation increases the workload of the operator. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0025] Please also read Figures 1 to 3 , the iron tower anti-fall device provided by the utility model is now described. The iron tower anti-fall device includes a slide rail 1, a fall arrester 2, a rocker arm 3, a rib plate 4, a limit plate 5 and an elastic member 6. The slide rail 1 is fixedly mounted on the iron tower; the fall arrester 2 is mounted on the slide rail 1 and can slide out from the bottom end of the slide rail 1; the rocker arm 3 is hingedly arranged on the fall arrester 2; the rib plate 4 is mounted on the slide rail 1, and the rocker arm 3 has the freedom to swing in the direction close to or away from the rib plate 4 on the fall arrester 2; the limit plate 5 is mounted between the rib plate 4 and the slide rail 1, and when the fall arrester 2 moves downward, one end of the rocker arm 3 can be against the limit plate 5; the elastic member 6 is mounted between the limit plate 5 and the rocker arm 3, and is used to drive one end of the rocker arm 3 to move in the direction close to the rib plate 4.
[0026] The iron tower anti-fall device provided in this embodiment is compared with the prior art. The slide rail 1 is provided, and the slide rail 1 is fixedly installed on the iron tower. The slide rail 1 and the rib plate 4 are an integrally formed structure, and are formed by T-shaped steel processing. A limit plate 5 is fixedly installed at the bottom end of the slide rail 1, and the limit plate 5 is fixedly installed on the side of the rib plate 4. A swing rod 3 is hingedly arranged on the anti-fall device 2. When the anti-fall device 2 is installed on the slide rail 1, the elastic member 6 drives the swing rod 3 to rotate, and the bottom end of the swing rod 3 is tilted in the direction close to the rib plate 4. In this application, when the anti-fall device 2 is installed, the end of the swing rod 3 will swing in the direction away from the rib plate 4 when it moves to the limit plate 5, so as not to affect the upward movement of the anti-fall device 2. When the anti-fall device 2 moves upward to make the swing rod 3 disengage from the limit plate 5, the swing rod 3 is driven by the elastic member 6 to swing the bottom end in the direction close to the rib plate 4, so that when the anti-fall device 2 falls freely, the swing rod 3 is limited on the limit plate 5 to prevent the anti-fall device 2 from disengaging from the slide rail 1. The limiting plate 5 can be directly fixed on the slide rail 1 by welding, thus avoiding unnecessary disassembly operations, making it easy to use and reducing the workload of operators.
[0027] Specifically, in this embodiment, the limit plate 5 is fixedly installed on one side of the rib plate 4 by welding, and the limit plate 5 is protruding from the side of the rib plate 4. A clearance for avoiding the rib plate 4 and the limit plate 5 is provided on the fall arrester 2, and the rocker arm 3 is hingedly arranged on the side wall of the clearance.
[0028] Specifically, in this embodiment, the structure of the fall arrester 2 adopts the existing technology, which will not be elaborated here.
[0029] In some embodiments, the swing rod 3 may be Figure 2 , Figure 3 See also Figure 2 , Figure 3 There are two swing rods 3, which are hingedly arranged on the anti-fall device 2, and the rib plate 4 is located between the two swing rods 3. There are two swing rods 3, and the limit plates 5 are fixedly installed on both sides of the rib plate 4. When the anti-fall device 2 is installed on the slide rail 1, before the staff climbs, the anti-fall device 2 will move downward freely and make the swing rods 3 on both sides of the rib plate 4 abut against the limit plates 5. Improve the stability of the position of the anti-fall device 2. It can play a better supporting role.
[0030] In some embodiments, the swing rod 3 may be Figure 2 , Figure 3 See also Figure 2 , Figure 3 The end of the swing rod 3 is rotatably provided with a roller 31, and the axis of the roller 31 is arranged parallel to the axis of the swing rod 3 on the anti-fall device 2. The end of the swing rod 3 is rotatably provided with a roller 31, and the roller 31 is used to abut against the rib plate 4 or the limit plate 5. This makes it more convenient to push the anti-fall device 2 to move upward.
[0031] Preferably, in this embodiment, when the worker climbs up the upper plate, the roller 31 at the end of the swing rod 3 abuts against the rib plate 4 and is rolled on the rib plate 4. The swing rod 3 gradually tilts from top to bottom toward the rib plate 4. When the fall arrester 2 has a tendency to move downward, the two swing rods 3 are forced to swing so that the roller 31 moves toward the rib plate 4, which can play a certain anti-slip effect.
[0032] In some embodiments, the swing rod 3 may be Figure 3 See the structure shown. Figure 3The middle part of the swing rod 3 is hingedly arranged on the anti-fall device 2, and the elastic member 6 is located at the end of the swing rod 3 away from the roller 31, and in the free state, the end of the swing rod 3 connected to the elastic member 6 is located outside the anti-fall device 2. A through groove for mounting the lower end of the swing rod 3 is provided on the anti-fall device 2, and the middle part of the swing rod 3 is hingedly arranged inside the through groove, and the lower end of the swing rod 3 is tilted toward the direction close to the rib plate 4 through the through groove. The elastic member 6 is installed at the other end of the swing rod 3 to drive the swing rod 3 to swing so that the end located inside the through groove rotates toward the direction close to the rib plate 4, so that the lower end of the swing rod 3 is always tilted toward the side close to the rib plate 4. When the anti-fall device 2 needs to be removed from the slide rail 1, the staff can press the end of the swing rod 3 provided with the elastic member 6 to make the other end of the swing rod 3 be stored inside the through groove, so that it can be removed from the slide rail 1 avoiding the limit plate 5, and the structure is simple and easy to operate.
[0033] Specifically, in the present embodiment, a pressing portion abutting against the elastic member 6 is provided at one end of the rocker arm 3. When in a free state, the pressing portion is located on the outside of the anti-fall device 2. When the anti-fall device 2 needs to be removed from the slide rail 1 at a later time, the rocker arm 3 can be flipped by pressing the pressing portion, thereby allowing the other end of the rocker arm 3 to be released from the limit of the limit plate 5.
[0034] In some embodiments, the elastic member 6 may be Figure 3 See the structure shown. Figure 3 The elastic member 6 includes two elastic plates 61 arranged at an angle, and the two elastic plates 61 are respectively against the swing rod 3 and the anti-fall device 2. The elastic member 6 is composed of two elastic plates 61, and the two elastic plates 61 are an integrally formed structure. When one end of the swing rod 3 is pressed, the elastic plate 61 can be deformed, thereby generating a certain elastic force, so that the lower end of the swing rod 3 always keeps tilting toward the side close to the slide rail 1.
[0035] Specifically, in this embodiment, the elastic plate 61 has better stability than the spring, which prevents the elastic member 6 from being displaced during use.
[0036] In some embodiments, the elastic member 6 may be Figure 2 , Figure 3 See also Figure 2 , Figure 3 A groove for installing the elastic member 6 is provided on the fall arrester 2, and the connection of the two elastic plates 61 abuts against the inner wall of the groove. A groove for installing the elastic member 6 is provided on the fall arrester 2, and when the elastic member 6 is installed inside the groove, the connection of the two elastic plates 61 on the elastic member 6 abuts against the inner wall of the groove, thereby improving the stability of the installation position of the elastic member 6.
[0037] Specifically, in this embodiment, a hinge shaft is fixedly mounted on the swing rod 3, and both ends of the hinge shaft are rotatably arranged on the inner wall of the groove, and the position of the elastic member 6 is limited by the hinge shaft and the inner wall of the groove. In combination with the end of the swing rod 3, the elastic member 6 can be prevented from slipping out of the groove.
[0038] In some embodiments, the above-mentioned limit plate 5 can be used as follows: Figure 1 See the structure shown. Figure 1 The bottom of the limit plate 5 is tilted to have a chamfer that facilitates the bottom end of the guide swing rod 3 to swing outward. When the slide rail 1 is installed on the iron tower, the lower end of the limit plate 5 is chamfered, so that when the fall arrester 2 is installed, the swing rod 3 on the fall arrester 2 can automatically swing so that the bottom end of the swing rod 3 swings away from the rib plate 4, which is convenient for installing the fall arrester 2 on the slide rail 1.
[0039] In some embodiments, the above-mentioned fall arrester 2 can be used as follows Figure 1 , Figure 2 and Figure 3 See also Figure 1 , Figure 2 and Figure 3 , a guide roller 21 is rotatably provided on the fall arrester 2, and the guide roller 21 is rollingly provided on the slide rail 1. A through hole for being fitted onto the slide rail 1 is provided on the fall arrester 2, and a space for avoiding the rib plate 4 and the limit plate 5 is provided on one side of the through hole, and the side provided with the space is attached to the slide rail 1, and guide rollers 21 are rotatably provided on the other three side surfaces. The rotating shaft of the guide roller 21 is rotatably provided on the side wall of the fall arrester 2. And the outer wall of the guide roller 21 protrudes from the inner wall of the fall arrester 2. By providing the guide roller 21, the fall arrester 2 can move more smoothly on the slide rail 1, which is convenient for the staff to climb.
