DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. For easy description, the terms "vertical", "horizontal", "left", "right", "up", "down", "inner", "outer", "bottom" and the like used in the specification indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0039] Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] As shown in the accompanying drawings, Figures 1-2 A falling prevention device includes a stainless steel wire 1, a wind deviation prevention device 3 and a climbing self-locking device 2.

[0041] The stainless steel wire 1 is fixed vertically on the outside of the tower body by the prior art, and provides safety protection for workers climbing the tower. The windage device 3 is used to fix the stainless steel wire 1 on the outside of the tower body, so as to prevent the stainless steel wire 1 from contacting the tower body and prevent the stainless steel wire 1 from shaking. The climbing self-locking device 2 can slide up and down along the stainless steel wire 1, and the worker can connect the safety rope with the climbing self-locking device 2 when climbing the tower. The climbing self-locking device 2 can lock the stainless steel wire 1 to prevent accidents when the worker falls.

[0042] As shown in the accompanying drawings, Figures 3-6 The climbing self-locking device 2 includes a shell 21, a locking rod 22, a first fixing column 23, a second fixing column 24 and a third fixing column 25.

[0043] The shell 21 is the main part of the climbing self-locking device 2, and the shell 21 includes an upper cover 211, a lower cover 212 and an extrusion pipe 213.

[0044] The upper cover 211 and the lower cover 212 are both flat plate structures, and the upper cover 211 and the lower cover 212 are arranged in parallel with each other. The upper cover 211 and the lower cover 212 are installed and fixed by three fixing columns, and the edge position between the upper cover 211 and the lower cover 212 is provided with a side plate.

[0045] The extrusion pipe 213 is a half-enclosed tubular structure with a circular arc cross section, and the opening direction is towards the upper cover 211. The extrusion pipe 213 is integrally arranged with the lower cover 212 on one side in the length direction. The gap passage between the extrusion pipe 213 and the upper cover 211 can allow the stainless steel wire 1 to enter and exit the extrusion pipe 213, and the half-enclosed structure of the extrusion pipe 213 can better wrap and accommodate the stainless steel wire 1. In particular, in order to facilitate the sliding of the climbing self-locking device 2 on the stainless steel wire 1 and prevent excessive friction between the edge position of the extrusion pipe 213 and the stainless steel wire 1, the two ends of the extrusion pipe 213 are both provided with chamfers.

[0046] As shown in the accompanying drawings, Figures 4-7 The two ends of the length direction of the locking rod 22 are respectively an extrusion head 221 and a connecting head 222, and the extrusion head 221 is arranged towards the extrusion pipe 213. A through hole is formed in the middle position of the locking rod 22 for the first fixing column 23 to pass through.

[0047] The first fixed column 23 is a cylindrical column structure, and the first fixed column 23 is perpendicular to the lower cover 212 and fixed between the upper cover 211 and the lower cover 212. The locking rod 22 is sleeved on the first fixed column 23 and rotates around the first fixed column 23, so that the locking rod 22 can reciprocate within a certain angle range along the axis of the first fixed column. Since the sleeving position of the locking rod 22 and the first fixed column 23 is located at the middle position of the locking rod 22, the swinging direction of the connecting head 222 is opposite to that of the extrusion head 221 during the swinging of the locking rod 22.

[0048] The second fixed column 24 and the third fixed column 25 are used to realize the mounting and fixing between the upper cover 211 and the lower cover 212, and the second fixed column 24 and the third fixed column 25 are respectively located on both sides of the swinging direction of the locking rod 22. The second fixed column 24 is located at one end of the extrusion head 221, and the second fixed column 24 and the side wall between the upper cover 211 and the lower cover 212 can abut against the locking rod 22 during the swinging of the locking rod 22, so as to avoid that the swinging amplitude of the locking rod 22 is too large.

[0049] The extrusion head 221 can approach or move away from the extrusion pipe 213 during the swinging of the locking rod 22. When the extrusion head 221 approaches the extrusion pipe 213, the extrusion head 221 extends out of the shell 21 between the upper cover 211 and the lower cover 212, and at this time the extrusion head 221 cooperates with the extrusion pipe 213 to clamp the stainless steel wire 1, so as to prevent the worker from falling; when the extrusion head 221 moves away from the extrusion pipe 213, the extrusion head 221 returns to the space of the shell 21 between the upper cover 211 and the lower cover 212, and at this time the extrusion head 221 and the extrusion pipe 213 have no clamping and fixing effect on the stainless steel wire 1, and the worker can drive the climbing self-locking device 2 to slide freely along the stainless steel wire 1.

[0050] The extrusion head 221 is provided with a pattern groove 2211 adapted to the length direction of the stainless steel wire 1, the pattern groove 2211 is concave in the end of the extrusion head 221, and the groove bottom is provided with a texture for increasing the friction coefficient, so as to strengthen the clamping and fixing ability of the stainless steel wire 1.

[0051] A first elastic member 231 is arranged between the first fixed column 23 and the locking rod 22, and the first elastic member 231 can be a torsion spring or a spring. When the connecting head 222 swings towards the direction away from the third fixed column 25, the extrusion head 221 swings in the opposite direction, and during the process that the extrusion head 221 returns to the space of the shell 21 between the upper cover 211 and the lower cover 212, the first elastic member 231 will be compressed, so that the first elastic member 231 will apply a elastic force to the locking rod 22 in the natural state to maintain the natural clamping effect of the extrusion head 221 and the extrusion pipe 213 on the stainless steel wire 1.

[0052] The connecting head 222 protrudes from the shell 21, and the connecting head 222 is provided with a circular through hole for connecting with other safety ropes or devices.

[0053] As shown in the accompanying drawings Figures 5-6 and the accompanying drawings Figures 8-10 The climbing self-locking device 2 further comprises a movable baffle 26, a fourth fixed column 27, a lifting column 28 and a reset assembly 29.

[0054] The movable baffle 26 is a plate-shaped structure arranged between the upper cover 211 and the locking rod 22, the main body part of which is located within the range of the shell 21 between the upper cover 211 and the lower cover 212, and only the actuating head 261 at one end thereof is located outside the shell 21. The movable baffle 26 is used to shield the gap passage between the upper cover 211 and the extrusion pipe 213 after the stainless steel wire 1 enters the extrusion pipe 213, so as to prevent the stainless steel wire 1 from being self-disengaged from the extrusion pipe 213.

[0055] The end of the movable baffle 26 away from the actuating head 261 is sleeved on the fourth fixed column 27 and reciprocally swings within a certain angle range with the fourth fixed column 27 as the pivot.

[0056] The fourth fixed column 27 perpendicular to the lower cover 212 is located between the upper cover 211 and the lower cover 212 and on the side close to the extrusion pipe 213. Therefore, in the process of swinging, the side of the movable baffle 26 towards the extrusion pipe 213 can be close to or away from the extrusion pipe 213. And when the movable baffle 26 is in the position close to the extrusion pipe 213, the distance between the movable baffle 26 and the extrusion pipe 213 is less than the diameter of the stainless steel wire 1, at this time the movable baffle 26 has the effect of preventing the stainless steel wire 1 from being disengaged; and when the movable baffle 26 is in the position away from the extrusion pipe 213, the distance between the movable baffle 26 and the extrusion pipe 213 is greater than or equal to (usually greater than) the diameter of the stainless steel wire 1, at this time the worker can dismount the climbing self-locking device 2 from the stainless steel wire 1.

[0057] In order to avoid the movable baffle 26 from interfering with the second fixed column 24 in the process of swinging, a stroke slot 262 is arranged at the corresponding position of the movable baffle 26, which allows the second fixed column 24 to freely enter and exit, so as to ensure that the movable baffle 26 can swing smoothly.

[0058] The movable baffle 26 is further provided with a limiting slot 263, which cooperates with the lifting column 28 to limit the movable baffle 26, so as to prevent the movable baffle 26 from swinging and causing the stainless steel wire 1 in the extrusion pipe 213 to be disengaged.

[0059] Specifically, the lifting column 28 comprises a second elastic member 284 and a first column body 281, a second column body 282 and a third column body 283 which are integrally arranged and coaxial. The lifting column 28 is perpendicular to the lower cover 212 and axially movable between the upper cover 211 and the lower cover 212. The upper cover 211 and the lower cover 212 are both provided with through holes so that the first column body 281 can pass through the upper cover 211 and the third column body 283 can pass through the lower cover 212. The second column body 282 is located between the first column body 281 and the third column body 283, and the diameters of the first column body 281 and the third column body 283 are both smaller than the diameter of the second column body 282.

[0060] The second elastic member 284 is located between the lower cover 212 and the second column body 282. In the embodiment, the second elastic member 284 is a spring, and the diameter of the spring is smaller than the diameter of the second column body 282. The spring sleeved on the third column body 283 is compressed when the lifting column 28 moves axially towards the lower cover 212, so that the second elastic member 284 can exert an elastic force on the second column body 282. In the natural state of the second elastic member 284, the top of the first column body 281 passes through and is located in a position protruding from the upper cover 211.

[0061] The limiting groove 263 is in a U-shaped overall, and its opening is towards the lifting column 28. The limiting groove 263 is composed of an inner side groove 2631 and an outer side groove 2632. The inner side groove 2631 is in a circular arc shape, and its contour shape is matched with the contour shape of the first column body 281, and the second column body 282 cannot enter the inner side groove 2631; the opening degree of the outer side groove 2632 is larger, and it is in a V-shaped overall, and its contour size allows the second column body 282 to enter. Since the diameter of the second column body 282 is larger than that of the first column body 281, and the second column body 282 cannot enter the inner side groove 2631, when the second column body 282 enters the limiting groove 263, the second column body 282 is clamped in the outer side groove 2632, at this time, the second column body 282 is clamped with the limiting groove 263, so that the movable baffle 26 cannot further swing towards the side where the lifting column 28 is located. When the first column body 281 enters the limiting groove 263, the first column body 281 can directly enter the inner side groove 2631. Compared with the position of the movable baffle 26 when the second column body 282 is clamped in the outer side groove 2632, at this time, the movable baffle 26 can further swing towards the side where the lifting column 28 is located, the distance between the inner side groove 2631 and the axis of the lifting column 28 is further reduced, and the circular arc shape of the inner side groove 2631 also facilitates the free rotation between the first column body 281 and the inner side groove 2631.

[0062] In the utility model, when the second column 282 enters the limiting groove 263, the movable baffle 26 is in the state of extending between the upper cover 211 and the lower cover 212 of the shell 21 and is continuously kept in the current state due to the limiting effect of the second column 282 and the limiting groove 263; and when the first column 281 enters the limiting groove 263, the movable baffle 26 is in the state of being able to extend or retract from the shell 21 at will.

[0063] The climbing self-locking device 2 is in the natural state, the top of the first column 281 penetrates the upper cover 211 and protrudes from the upper cover 211 due to the elastic force of the second elastic member 284, at this time, the second column 282 of the lifting column 28 is clamped with the outer side groove 2632 of the limiting groove 263, the movable baffle 26 is in the state of extending between the upper cover 211 and the lower cover 212 of the shell 21, the movable baffle 26 is limited to the position close to the extrusion pipe 213 and cannot swing freely. In use, the worker presses the first column 281 against the elastic force of the second elastic member 284, the first column 281 is pressed into the upper cover 211 at the same time the second column 282 moves downward to disengage from the limiting groove 263, the first column 281 enters the limiting groove 263. At this time, the movable baffle 26 can be away from the extrusion pipe 213, so that the stainless steel wire 1 can enter the extrusion pipe 213. Then, the worker releases the pressure on the first column 281, the second column 282 enters the limiting groove 263 under the elastic force of the second elastic member 284 and maintains the clamping state with the outer side groove 2632, so that the second column 282 and the limiting groove 263 cooperate to limit the movable baffle 26.

[0064] As shown in the accompanying drawings, Figure 5 and the accompanying drawings, Figure 6 The reset assembly 29 includes a fixed rod 291 and a third elastic member 292. The fixed rod 291 is fixedly connected to the movable baffle 26, and the two ends of the third elastic member 292 are fixed to the lifting column 28 and the fourth fixed column 27 respectively. When the movable baffle 26 rotates towards the direction away from the extrusion pipe 213, the movable baffle 26 drives the fixed rod 291 to press the third elastic member 292, so that the third elastic member 292 can drive the movable baffle 26 to rotate towards the direction of the extrusion pipe 213 under the elastic force.

[0065] Particularly, in order to facilitate the worker to push the movable baffle 26 into the shell 21, the push head 261 at the end of the movable baffle 26 is arranged outside the shell 21. A groove for the movable baffle 26 to pass through is also arranged on the side plate between the upper cover 211 and the lower cover 212. A roller 2611 capable of rolling along the stainless steel wire 1 is also arranged on the push head 261.

[0066] As shown in the accompanying drawings, Figure 11 and the accompanying drawings, Figure 12 The wind deflection prevention device 3 includes a mounting plate 31, a positioning plate 32, a connecting rod 33 and a limiting tube 34.

[0067] The mounting plate 31 is provided with a through hole for the bolt to pass through, so that the whole wind deviation prevention device 3 can be fixed on the iron tower. The two end plates of the mounting plate 31 have a certain included angle, and the positioning plate 32 is fixedly connected with the mounting plate 31 through bolts.

[0068] The connecting rod 33 is an L-shaped structure, one end of which is integrally arranged with the positioning plate 32, and the other end is fixedly connected with the middle part of the limiting tube 34. In this embodiment, the two ends of the connecting rod 33 are perpendicular to each other, and the length of the end fixedly connected with the limiting tube 34 is greater than the thickness of the shell 21.

[0069] The limiting tube 34 is a half-open tubular structure, and the inner diameter of the limiting tube 34 is not less than the outer diameter of the stainless steel wire 1. Generally, the inner diameter of the limiting tube 34 is slightly larger than the outer diameter of the stainless steel wire 1, so that the limiting tube 34 can accommodate and limit the stainless steel wire 1.

[0070] Specifically, the limiting tube 34 is continuously provided with a first opening 341, a second opening 342 and a third opening 343 along the axial direction of the limiting tube 34, and the first opening 341, the second opening 342 and the third opening 343 are all large enough for the stainless steel wire 1 to pass through. Moreover, the first opening 341 and the third opening 343 have the same opening direction and size, while the second opening 342 has an included angle with the first opening 341. Thus, when the stainless steel wire 1 is loaded into the limiting tube 34, the worker can make the stainless steel wire 1 pass through the three openings in sequence by bending and twisting the stainless steel wire 1 to a certain extent. The three openings arranged in sequence have different opening directions, so that the stainless steel wire 1 vertically arranged on the iron tower cannot come out of the limiting tube 34 by itself. Because the limiting tube 34 closely fits the stainless steel wire 1, the friction between the limiting tube 34 and the stainless steel wire 1 due to shaking is effectively reduced, and the problem of wear and breakage of the stainless steel wire 1 is avoided. Moreover, the limiting tube 34 is rigidly connected with the iron tower, so that the shaking amplitude of the stainless steel wire 1 is greatly reduced.

[0071] As shown in Figs. 6 and 7, the connecting rod 33 is an L-shaped structure, one end of which is integrally arranged with the positioning plate 32, and the other end is fixedly connected with the middle part of the limiting tube 34. In this embodiment, the two ends of the connecting rod 33 are perpendicular to each other, and the length of the end fixedly connected with the limiting tube 34 is greater than the thickness of the shell 21. Figures 1-2 Figures 11-12 As shown in Figs. 6 and 7, the connecting rod 33 is an L-shaped structure, one end of which is integrally arranged with the positioning plate 32, and the other end is fixedly connected with the middle part of the limiting tube 34. In this embodiment, the two ends of the connecting rod 33 are perpendicular to each other, and the length of the end fixedly connected with the limiting tube 34 is greater than the thickness of the shell 21.

[0072] ​And the outer diameter of the limiting tube 34 is smaller than the inner diameter of the extrusion tube 213, so when the extrusion head 221 is away from the extrusion tube 213, the limiting tube 34 can also pass through the gap between the extrusion head 221 and the extrusion tube 213. Thus, when the worker drives the climbing self-locking device 2 to continuously climb along the stainless steel wire 1, the climbing self-locking device 2 located below the wind deviation prevention device 3 can pass through the wind deviation prevention device 3 without obstacles, without manual adjustment by the worker, and the safety of the worker during climbing is ensured.

[0073] The implementation principle of the above embodiment is:

[0074] In the anti-falling device of the utility model, the stainless steel wire 1 is suspended and fixed on the iron tower, and after the stainless steel wire 1 enters a series of wind deviation prevention devices 3 arranged along the height direction of the tower body, the wind deviation prevention devices 3 firmly fix the stainless steel wire 1 outside the tower body. When the worker needs to climb the iron tower for aerial work, the worker wears the safety rope and ties the safety rope to the connecting head 222 of the climbing self-locking device 2. The direction of the climbing self-locking device 2 is adjusted, so that the extrusion tube 213 is parallel to the length direction of the stainless steel wire 1 and the driving head 261 is at the top of the climbing self-locking device 2. The first column 281 is pressed in the axial direction, and the second column 282 moves synchronously to disengage from the limiting groove 263. At this time, the driving head 261 can be driven towards the direction away from the stainless steel wire 1, and the movable baffle 26 can be retracted into the shell 21 away from the extrusion tube 213, so that the stainless steel wire 1 can enter the extrusion tube 213 through the gap between the extrusion tube 213 and the upper cover 211. Then, the worker releases the pressure on the first column 281 and the tension on the driving head 261, and the movable baffle 26 extends out of the shell 21 under the action of the third elastic member 292; and the second column 282 enters the limiting groove 263 and maintains the clamping state with the limiting groove 263 under the action of the elastic force of the second elastic member 284, so that the second column 282 cooperates with the outer groove 2632 of the limiting groove 263 to limit the movable baffle 26, preventing the movable baffle 26 from retracting into the shell 21. After the movable baffle 26 extends out of the shell 21, the gap between the movable baffle 26 and the extrusion tube 213 is smaller than the diameter of the stainless steel wire 1, so that the climbing self-locking device 2 is firmly installed on the stainless steel wire 1. In the process of the worker climbing upwards, the connecting head 222 is continuously pulled upwards, and the extrusion head 221 swings downwards while the connecting head 222 swings upwards, so that the extrusion head 221 retracts into the shell 21, facilitating the upward sliding of the climbing self-locking device 2 along the stainless steel wire 1. When an accidental falling occurs, the worker drives the connecting head 222 to swing downwards rapidly, and the extrusion head 221 swings upwards reversely, the extrusion head 221 rapidly extends out of the shell 21, and the pattern groove 2211 on the extrusion head 221 cooperates with the extrusion tube 213 to quickly clamp the stainless steel wire 1, effectively preventing the worker from falling, and protecting the safety of the worker throughout the process.

[0075] When the worker climbs upward and encounters the wind deflection device 3, the connecting rod 33 can pass through the gap between the movable baffle 26 and the extrusion pipe 213, and the limiting pipe 34 can also pass through the gap between the extrusion head 221 and the extrusion pipe 213, so that the climbing self-locking device 2 below can pass through the wind deflection device 3 without obstacles, and the worker does not need to manually adjust the position of the climbing self-locking device 2 during the process of climbing the tower, which more effectively ensures the safety of the worker during the climbing process.
