Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only some embodiments of the present invention, not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment provides an omnidirectional flexible guide rail system for preventing a pole tower from falling, which comprises: a plurality of anti-falling assemblies, auxiliary steering devices and anti-falling devices in different directions;
the anti-falling assemblies in different directions are fixed on the angle steel of the tower, and are used for providing guide rails in different directions for the falling devices so that the falling devices can move along the angle steel in the corresponding directions;

when the fall arrester moves along a section of the guide rail into the auxiliary steering device, the auxiliary steering device switches the fall arrester from the current guide rail to the guide rail in the direction of movement by rotating.
Because the safety measures of wearing safety belts and combining anti-falling ropes are difficult to adapt to the moving requirements of high-altitude maintenance operators in different directions in the maintenance process of the existing high-voltage transmission line Gao Kongyun. Therefore, the invention provides an omnidirectional flexible guide rail system for preventing the falling of a pole tower, which comprises a plurality of falling prevention assemblies, auxiliary steering devices and falling stoppers in different directions; the anti-falling device can move along the anti-falling assemblies in different directions to meet the moving requirements of the high-altitude maintenance operators in different directions, and meanwhile, the auxiliary steering device can realize seamless switching between different guide rails when the anti-falling device needs to change the moving directions, so that the whole process protection is provided for the high-altitude maintenance operators. The auxiliary steering device which is convenient for the falling stopper to switch between the guide rails in different directions is additionally arranged on the falling prevention guide rail, so that personnel can be protected in a full closed loop in climbing operations in different directions of the pole tower.
The present invention will be further described with reference to the accompanying drawings by way of example only, as being provided with a vertical rail assembly and a lateral rail assembly.
Referring to fig. 1-3, in an embodiment of the present invention, a set of guide rail assemblies are respectively arranged along the vertical direction and the transverse direction, and the auxiliary steering device 9 is fixed on the angle steel where the two guide rail assemblies meet through the auxiliary steering device angle steel fixing device 13. The high-altitude maintenance operator climbs the foot nail 14 through the pole tower to perform climbing operation.
Specifically, the auxiliary steering device 9 is structured as shown in fig. 2. The auxiliary steering device 9 mainly plays a role of safely switching the fall arrester 10 from a vertical guide rail to a transverse guide rail, and comprises an auxiliary steering device and an auxiliary steering device angle steel fixing device 13 (namely an angle steel fixing seat 19).
The auxiliary diverter includes a guide anti-slip disc 21, a rotating core 20 and a rotating core guide rail 18. The angle steel fixing seat 19 fixes the auxiliary steering device 9 on the angle steel of the tower, and the guiding anti-drop disc 21 is fixed on the angle steel fixing seat 19. The guiding anti-drop disc 21 is circular in design, the circumference is provided with an anti-drop surface, a plurality of slots are formed in the anti-drop surface, and the vertical and transverse guide rails penetrate through the slots to be fixed on the guiding anti-drop disc. It can be seen that the ends of the length of guide rail end at the edge position of the guide anti-slip disc, and the central area of the guide anti-slip disc 21 is penetrated directly without the outer guide rail.
The rotating core 20 is arranged at the center of the guide rail anti-drop disc 21, and the rotating core guide rail 18 is arranged on the rotating core 20. When the rotating core 20 rotates the rotating core rail 18, the rotating core rail 18 forms a circular area. The ends of the vertical and horizontal guide rails are connected to the circumference of the circular area where the fall arrester 10 can move through the slot to other external guide rails, and at the same time, the fall-off preventing surface of the guide fall-off preventing plate 21 limits the fall-off of the fall arrester 10. As shown in fig. 3, the rotating core rail 18 is located on the same plane as the other external rails.
The auxiliary diverter is mainly used for the function of the auxiliary fall arrester 10 to switch from a vertical rail to a lateral rail. When the fall arrester 10 enters the guiding anti-drop disc along the flexible guide rail, the fall arrester 10 needs to rotate a certain angle, and the open slot is aligned with the end bracket of the guide rail to enter the auxiliary steering device. When the fall arrestor 10 moves to the rotary core guide rail, an operator can stir the rotary core to rotate by rotating the fall arrestor 10. If the fall arrestor 10 needs to be switched from a vertical rail to a transverse rail, the fall arrestor is only required to be rotated by 90 degrees to enable the rotary core guide rail to be opposite to the transverse guide rail, and at the moment, the direction change of the vertical rail and the transverse rail is completed.
The vertical guide rail and the transverse guide rail of the conventional flexible guide rail system are independent, if the vertical guide rail and the transverse guide rail are required to be transited, the falling stopper is required to be transited to other guide rails after being removed from the conventional guide rail, and the falling stopper is removed in the switching process, so that the potential safety hazard is very high. In the embodiment, an auxiliary steering device which is convenient for the anti-falling device to be seamlessly switched from the vertical guide rail to the transverse guide rail is additionally arranged on the flexible anti-falling guide rail, so that the full closed loop protection of personnel in the vertical and transverse climbing operation of the pole tower is ensured.
Referring to fig. 1-5, in another embodiment of the present invention, the vertical guide rail assembly and the horizontal guide rail assembly each include an angle steel fixing clamp, a guide rail fixing bracket, a flexible anti-falling guide rail, and a slack adjuster; two ends of the flexible anti-falling guide rail are fixedly connected with the two guide rail fixing brackets respectively; the guide rail fixing bracket is fixed on the angle steel fixing clamp or the auxiliary steering device; the angle steel fixing clamp is fixed on the angle steel of the tower; the tightness adjusting device is arranged on the guide rail fixing support and used for adjusting tightness of the flexible anti-falling guide rail.
As shown in fig. 1, in the vertical anti-falling component, one end of the vertical flexible anti-falling guide rail 4 is fixedly connected with an anti-falling guide rail upper end fixing bracket 15 or an anti-falling guide rail lower end fixing bracket 11, and the other end of the vertical flexible anti-falling guide rail is fixed in the auxiliary steering device 9 through a flexible guide rail tail end bracket 8. The flexible anti-falling guide rail adopts stainless steel flexible steel strands, and has the advantages of low cost, easy molding, convenient construction and installation, strong comprehensive mechanical property, rust resistance and the like. Compared with the rigid guide rail, the manufacturing and mounting cost is greatly reduced, and the rigid guide rail is flexible in material, convenient to form and easy to mount. And the flexible anti-falling guide rail is adopted, so that the purpose that the anti-falling device is seamlessly switched from the vertical guide rail to the transverse guide rail is achieved for the first time, and the full closed-loop protection of the high-altitude operation of the tower is realized.
As shown in fig. 2, the vertical flexible rail end bracket 16 and the horizontal flexible rail end bracket 17 are blade-type end brackets, and the shapes of which are matched with the opening grooves 27 of the fall arresters. The blade type tail end bracket and the flexible guide rail are welded into a whole through a welding process, so that the problem that the falling stopper cannot pass through after the fixed bracket is additionally arranged at the tail end of the flexible guide rail is solved. Meanwhile, due to the blade-shaped structural characteristic of the tail end support, the falling protector can enter the steering device smoothly to steer.
As shown in fig. 1, a plurality of guide rail anti-swing brackets 5 which are uniformly distributed are arranged on the vertical flexible anti-falling guide rail 4 and the transverse flexible anti-falling guide rail 7, the guide rail anti-swing brackets 5 are fixed on the angle steel through a vertical angle steel fixing device or a transverse angle steel fixing device 12, and the other end of the guide rail anti-swing brackets is fixedly connected with the guide rail.
Because the anti-swing support on the existing flexible guide rail is not in direct contact with and fixed to the flexible guide rail, the deflection of the flexible guide rail in a certain range is limited by arranging a plurality of anti-swing supports with annular structures on the outer side of the circumference of the flexible guide rail. Because this kind of protective structure mode is fixed with flexible guide rail direct contact, in the in-service use in-process flexible guide rail easily produces to rock, and the moment that especially takes place to fall, because flexible guide rail rocks greatly and leads to falling locking distance to increase, can't satisfy the requirement that the high altitude was stopped to weigh down. Meanwhile, the anti-swing support of the annular structure is not beneficial to the passing of the anti-falling device, the anti-falling device needs to be rotated for many times to bypass the swing support to pass, and the operation efficiency is low. Therefore, the guide rail anti-swing bracket 5 is a blade type anti-swing bracket, so that the stability of the flexible guide rail can be ensured, and deflection and swing are not generated. Meanwhile, the blade-type anti-swing support structure is convenient for the falling protector to pass smoothly, and the operation process is safe and reliable.
As shown in the figure, when the guide rail assembly is fixed, two angle steel fixing clamps 22 are symmetrically distributed, and fixing is achieved through bolts.
Referring to fig. 6-7, in a further embodiment of the present invention, the fall protection assembly is further provided with a locking anti-theft alarm device 3. The device mainly plays the effect of monitoring that guide rail fixed bolster bolt becomes flexible, prevents that artificial dismantlement from stealing the anti-falling guide rail.
As shown in fig. 6, the anti-loose anti-theft alarm device 3 is installed in a cavity formed by two angle steel fixing jigs 22. The device realizes the monitoring to the guide rail fixed bolster is not hard up through the inside change of response cavity.
As shown in fig. 7, the anti-loose anti-theft alarm device 3 includes a spring contact 23 and an alarm module, and the alarm module includes a micro switch 26, a main control board 25, a lithium battery 24, a wireless communication module, and the like. The anti-loose anti-theft alarm device 3 is fixed in the cavity through angle steel fixing clamps 22 at two sides, and alarm spring contacts 23 are arranged on the upper panel and the lower panel of the anti-loose anti-theft alarm device 3. Once the angle steel fixing clamps 22 on the two sides are loosened or manually disassembled, the alarm spring contacts 23 on the upper panel and the lower panel automatically extend, the other ends of the spring contacts 23 are separated from the micro-switch 26 on the main control board 25, the state information of the micro-switch 26 is transmitted to the main control board 25, and the state alarm information is transmitted to the mobile phone end of a monitoring person in real time through the wireless communication module. So as to realize the purpose of locking, anti-theft and real-time alarming of the guide rail. The device adopts the design of low-power consumption narrowband internet of things, is always in a dormant mode in operation, and once the spring contact 23 is triggered, alarm state information is sent, and the lithium battery 24 is adopted for power supply, so that the device can continuously work for more than 1 year.
In the embodiment, the anti-loosening anti-theft alarm device 3 is additionally arranged on the guide rail fixing seat, so that the looseness of the guide rail bracket can be monitored in real time, the guide rail bracket and the guide rail can be prevented from being stolen, and the performance state of the anti-falling guide rail can be controlled.
In addition, fig. 8 is a schematic structural view of the fall arrester, which has an arrester opening groove 27 penetrating the rail end bracket on one side of the structure.
