Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude operation safety protection, in particular to a guide rail diverter device suitable for a steel strand guide rail. Background Art

[0002] The pole towers of overhead transmission lines are mainly angle steel towers and steel pipe towers. At present, when carrying out high-altitude operation and maintenance of transmission lines, it is generally adopted to install anti-fall rails on the outside of the pole towers to provide anti-fall protection for the maintenance workers. Before climbing, the maintenance workers need to wear fall arresters matching the rails and climb along the rails, so as to prevent the workers from falling and causing casualties during the climbing process of the tower.

[0003] At present, the anti-fall rails installed on the transmission line towers are mainly divided into two types according to the different structures and materials of the rails: hard guide rails and flexible steel strand rails. The anti-sway bracket device for suppressing the swing of the steel strand rails involved in this technical solution is mainly for steel strand rails or flexible rails with cylindrical cross-sections. The existing steel strand rails have the following shortcomings in preventing the fall: First, there are few deflectors installed on the existing transmission line steel strand rails, which makes it impossible for the fall arrester to switch freely in the horizontal and vertical directions on the rails; second, there is no connection between the traditional deflector and the rail, and after a long period of operation, the connection head between the deflector and the rail will be offset or the gap will increase, resulting in the obstruction of the fall arrester and the increase in the gap. It is easy to slip, which poses a great safety hazard; third, the installation of the traditional deflector is cumbersome, the cost is high, and the installation efficiency is low, which is not convenient for high-altitude construction.

[0004] Therefore, a guide rail diverter device suitable for a steel strand guide rail is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a guide rail diverter device suitable for a steel strand guide rail, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guide rail deflector device suitable for a stranded wire guide rail, comprising an angle steel of a main material of an iron tower and a fixed connection seat, wherein two fixed connection seats are provided, and the two fixed connection seats are respectively provided at two ends of the angle steel of the main material of the iron tower, a flexible guide rail is longitudinally fixedly provided between the two fixed connection seats, a deflector is provided on the outside of the flexible guide rail, a blade bracket is fixedly provided on the lower end of the front side wall of the angle steel of the main material of the iron tower, the right end of the blade bracket is clamped with the flexible guide rail, and a fall arrester is provided on the lower end of the flexible guide rail;

[0007] The steering gear includes a steering gear base, a front side wall of the steering gear base is fixedly provided with symmetrical limit blocks, the front side wall of the steering gear base is fixedly provided with four groups of support blocks, the front ends of the four groups of support blocks are fixedly provided with guide rail fixing brackets, a rotating core is rotatably provided inside the steering gear base, a limit pin is fixedly provided at the upper end of the rear end of the rotating core, a limit groove is provided at the rear side wall of the steering gear base corresponding to the limit pin, and an angle steel fixing clamp is fixedly provided at the rear end of the steering gear base.

[0008] Preferably, the side wall of the angle steel, the main material of the tower, is fixedly provided with evenly arranged threaded rods, the blade bracket is sleeved on the outside of the threaded rod, and the outside of the threaded rod is threadedly provided with a fastening nut at the front end of the blade bracket.

[0009] Preferably, the rotation angle of the rotating core is 90 degrees clockwise.

[0010] Preferably, the side wall of the guide rail fixing bracket is threadedly provided with symmetrical bolts, and the guide rail fixing bracket is fixedly arranged at the front end of the steering gear base by bolts, and the rear side wall is in contact with the front side wall of the support block.

[0011] Preferably, two limiting grooves are provided, and are located at the upper end and the left end behind the rotating core.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The steering gear in this application is fixed on the main material angle steel through the steering gear base and the angle steel fixing clamp seat. When the fall arrester enters the turntable core, it rotates 90° clockwise through the core, and the operator can switch from the vertical guide rail to the horizontal guide rail to achieve free reversing.

[0014] (1) Solve the problem that the fall arrester cannot switch from vertical to horizontal on the flexible guide rail, and when facing the change of direction, the fall arrester must be released from the guide rail before the change of direction can be carried out, which poses a great safety hazard;

[0015] (2) The guide rail fixing bracket on the steering gear adopts a horizontal structure design. When the fall arrester passes through the steering gear, it must be rotated 90 degrees to a side-lying posture before it can pass through the guide rail fixing bracket on the steering gear. Its side-lying posture can effectively prevent the fall arrester from escaping from the turntable at any steering angle, completely solving the safety hazard problem of the fall arrester passing through the steering gear;

[0016] (3) The guide rail fixing bracket adopts a horizontal structure design, and its overall structure sinks, ensuring that the height of the guide rail fixing bracket on the steering gear is consistent with the steel strand guide rail, solving the problem that the connection between the steering gear and the steel strand guide rail requires the use of a curved rail for transition. At the same time, since the overall structure sinks, there is no transition structure at the connection, which greatly improves its structural strength, greatly reduces the difficulty of installation, and saves costs;

[0017] (4) Strong installation adaptability, safe and stable installation. By fixing the device on the angle steel of the pole tower, the installation is convenient, safe and stable. The mounting bracket is provided with adjustable height adjustment holes to adapt to the installation height of the matching flexible track;

[0018] (5) Special anti-falling performance: The steering gear base is equipped with a limit device to prevent the anti-fall device from slipping when switching in the steering gear, ensuring that the anti-fall device is safe and reliable during the steering process and easy to switch;

[0019] (6) Strong passing performance of the fall arrester: The guide rail fixing bracket adopts a structural design that fits the contour of the fall arrester. When the fall arrester passes, it only needs to be slightly rotated at a certain angle to match the cross-section of the guide rail fixing bracket to pass safely and quickly;

[0020] (7) Efficient installation: The use of a steering gear suitable for a flexible guide rail can completely change the situation where there is a height difference when the steering gear installed on the rigid guide rail is connected to the rigid guide rail, and a slight angle deviation requires the rigid guide rail to be bent on site to adapt to different heights and angles on site, and the installation is extremely cumbersome and difficult;

[0021] (8) Safe and reliable: The steering gear with flexible guide rail is installed on the main material angle steel. It is not only firmly installed but also can provide a supporting force for the flexible guide rail connected to the steering gear. When the operator falls on the transverse flexible guide rail, it can play a better supporting role. Since the flexible guide rail and the steering gear are connected to form a whole through the bracket, there is no gap between the flexible guide rail and the steering gear. There will be no gap even if the operation time is long. The passing performance of the fall arrester is excellent. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example:

[0030] See also Figure 1-4 , the utility model provides a technical solution:

[0031] A guide rail diverter device suitable for a stranded wire guide rail, comprising an angle steel 1 of a main material of an iron tower and a fixed connection seat 2, wherein two fixed connection seats 2 are provided, and the two fixed connection seats 2 are respectively provided at both ends of the angle steel 1 of the main material of the iron tower, a flexible guide rail 4 is fixedly provided between the two fixed connection seats 2 in the longitudinal direction, a diverter 3 is provided outside the flexible guide rail 4, a blade bracket 5 is fixedly provided at the lower end of the front side wall of the angle steel 1 of the main material of the iron tower, the right end of the blade bracket 5 is clamped with the flexible guide rail 4, and a fall arrester 6 is provided at the lower end of the flexible guide rail 4;

[0032] The diverter 3 includes a diverter base 301, a front side wall of the diverter base 301 is fixedly provided with symmetrical limit blocks 302, the front side wall of the diverter base 301 is fixedly provided with four groups of support blocks 304, the front ends of the four groups of support blocks 304 are fixedly provided with guide rail fixing brackets 303, a rotating core 305 is rotatably provided inside the diverter base 301, a limit pin 306 is fixedly provided at the upper end of the rear end of the rotating core 305, a limit groove 307 is provided at the rear side wall of the diverter base 301 corresponding to the limit pin 306, an angle steel fixing clamp seat 308 is fixedly provided at the rear end of the diverter base 301, and the diverter base 301 and the angle steel fixing clamp seat 308 can be adapted to be installed on angle steels of various sizes and models, and have wide installation adaptability, stable and convenient installation.

[0033] The side wall of the angle steel 1, the main material of the iron tower, is fixed with evenly arranged threaded rods, the blade bracket 5 is sleeved on the outside of the threaded rod, and the outside of the threaded rod is threadedly provided with a fastening nut at the front end of the blade bracket 5.

[0034] The rotation angle of the rotating core 305 is 90 degrees clockwise. When the rotating core 305 rotates, the limiting pin limiting groove 307 of the fall arrester 6 limits the angle of the limiting pin 306, so that it only has the function of clockwise rotation of 0-90 degrees, and does not have the function of counterclockwise rotation.

[0035] The side wall of the guide rail fixing bracket 303 is threaded with symmetrical bolts. The guide rail fixing bracket 303 is fixed to the front end of the steering gear base 301 by bolts, and the rear side wall is in contact with the front side wall of the support block 304 .

[0036] There are two limiting grooves 307 , which are located at the upper end and the left end behind the rotating core 305 .

[0037] Working principle:

[0038] The flexible guide rail steering device clamps the angle steel 1 of the tower body by the steering device base 301 and the angle steel fixing clamp seat 308, and locks the screw nut at one end in turn to clamp the main angle steel 1 to complete the fixed installation of the device. The steering device base 301 and the angle steel fixing clamp seat 308 can be adapted to be installed on angle steels of various sizes and models, with wide installation adaptability, stable and convenient installation;

[0039] Before the anti-fall device 6 enters the diverter 3, the anti-fall device 6 is rotated so that the opening of the anti-fall device 6 is aligned with the reserved opening of the guide rail fixing bracket 303, so that the blade bracket 5 enters the rotating core 305;

[0040] After the fall arrester 6 enters the rotating core 305, the operator can continue to move upward, or after rotating 90° clockwise in the rotating core 305, the operator can only move toward the outside of the cross arm;

[0041] When the rotating core 305 rotates, the limiting pin limiting groove 307 limits the angle of the limiting pin 306, so that the limiting pin 306 can only rotate clockwise by 0-90 degrees, but not counterclockwise, thereby ensuring the possibility of the preventing device 6 slipping out of the steering gear 3 during the reversing process;

[0042] When the fall arrester 6 is not fully in place after rotating clockwise on the rotating core 305, the limit block 302 and the guide rail fixing bracket 303 will form an angle to limit the two ends of the fall arrester 6 to prevent the fall arrester 6 from separating from the rotating core 305, thereby ensuring the safety of the operator during operation.
