DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a tower for electric power engineering, including a tower main body 1 and an auxiliary climbing mechanism 2. The auxiliary climbing mechanism 2 includes a lifting platform 21, a hoisting mechanism 22 and a fall arrester 23. The hoisting mechanism 22 is connected to the lifting platform 21 through a lifting steel wire rope 24, and the fall arrester 23 is connected to the lifting platform 21 through a fall prevention steel wire rope 25. The tower main body 1 includes a steel frame 11, and the lifting platform 21 is slidably connected to the steel frame 11.

[0024] Power is provided by the auxiliary climbing mechanism 2 to drive the lifting platform 21 to slide along the steel frame 11 of the tower main body 1. By controlling the winding and lengthening of the lifting steel wire rope 24 of the auxiliary climbing mechanism 2, the driving height of the lifting platform 21 is controlled. When it is necessary to repair the tower main body 1, the staff stands on the lifting platform 21. Power is provided by the auxiliary climbing mechanism 2 to drive the lifting platform 21 to move, and the staff moves synchronously with the lifting platform 21, so as to lift the staff to the designated height position, which is beneficial to the repair of the tower main body 1.

[0025] When repairing the tower main body 1, the lifting platform 21 below it is automatically lifted by the auxiliary climbing mechanism 2 to drive the personnel to rise or fall. By installing the auxiliary climbing mechanism 2 on the tower main body 1, it replaces the conventional manual climbing, which saves time and effort, has a high climbing efficiency and a fast speed, and is beneficial to the repair.

[0026] The fall arrester 23 is a conventional fall prevention structure. The fall arrester 23 is connected to the lifting platform 21 through a fall prevention steel wire rope 25. When the lifting platform 21 moves upward normally, the fall prevention steel wire rope 25 is normally wound by the fall arrester 23. When the lifting platform 21 moves downward normally, the fall prevention steel wire rope 25 is normally lengthened by the fall arrester 23. When the lifting platform 21 accidentally falls at a high speed, the pulling speed of the fall prevention steel wire rope 25 increases, the internal gear of the fall arrester 23 rotates at an accelerated speed, and the pawl makes a centrifugal movement to engage the ratchet wheel, so as to quickly complete self-locking and achieve fall prevention, ensuring the safety of the lifting platform 21 during the lifting and lowering process.

[0027] Among them, a guardrail 211 is provided on the lifting platform 21.

[0028] Among them, there are three groups of guardrails 211, which are respectively located on both sides and the rear of the lifting platform 21. The safety during the lifting process is improved by strengthening the protection of the guardrails 211.

[0029] Among them, a slider 212 is fixedly arranged on one side edge of the lifting platform 21. A groove body adapted to the slider 212 is opened on the iron frame 11 of the iron tower main body 1, and the slider 212 is slidably embedded in the groove body of the iron frame 11. Driven by the hoisting mechanism 22, the slider 212 of the lifting platform 21 slides along the groove body of the iron frame 11 of the iron tower main body 1.

[0030] Among them, both the hoisting mechanism 22 and the anti-falling device 23 are fixedly arranged on the upper part of the iron tower main body 1. The hoisting mechanism 22 is used as a power source, and the anti-falling device 23 plays a role in preventing falling, improving the lifting safety, and can brake and lock itself emergently in case of accidental falling.

[0031] Among them, the hoisting mechanism 22 includes a motor 221. The output shaft of the motor 221 is connected to a reducer seat 222, and the output shaft of the reducer seat 222 is connected to a reel 223. When the motor 221 works, it is transmitted through the reducer seat 222 to drive the reel 223 to rotate.

[0032] Among them, one end of the lifting steel wire rope 24 is wound and fixed on the reel 223, and the other end of the lifting steel wire rope 24 is fixedly connected to the lifting platform 21. When the reel 223 rotates, the extension or winding of the lifting steel wire rope 24 is realized, and the extension or winding of the lifting steel wire rope 24 is controlled by the number of rotation turns and the rotation direction of the motor 221.

[0033] Among them, a base 12 is arranged at the bottom of the iron tower main body 1. The base 12 is made of concrete structure, and the iron tower main body 1 is fixed on the ground through the base 12.

[0034] Among them, the iron tower main body 1 includes a top frame 13. The top frame 13 is one of the components of the head of the electric power iron tower main body 1, is installed at the top of the iron tower main body 1, and plays a role in supporting the power line. The structural shape of the top frame 13 is selected according to the use requirements.

[0035] Working principle: The lifting platform 21, the hoisting mechanism 22 and the anti-falling device 23 form the auxiliary climbing mechanism 2. The hoisting mechanism 22 and the anti-falling device 23 are installed on the upper part of the iron tower main body 1, and the lifting platform 21 is placed at the lower part of the iron tower main body 1. The hoisting mechanism 22 is connected to the lifting platform 21 through the lifting steel wire rope 24, and the anti-falling device 23 is connected to the lifting platform 21 through the anti-falling steel wire rope 25. When maintaining the iron tower main body 1, the staff stands on the lifting platform 21, and the hoisting mechanism 22 works to provide power, driving the lifting platform 21 to slide along the iron frame 11. By controlling the winding and unwinding of the lifting steel wire rope 24 of the hoisting mechanism 22, the driving height of the lifting platform 21 is controlled, and the staff is lifted to the designated height position, which is beneficial to the maintenance of the iron tower main body 1. The anti-falling device 23 is a conventional anti-falling structure. When the lifting platform 21 moves upward normally, the anti-falling steel wire rope 25 is normally wound by the anti-falling device 23. When the lifting platform 21 moves downward normally, the anti-falling steel wire rope 25 is normally extended by the anti-falling device 23. When the lifting platform 21 accidentally falls at high speed, the pulling speed of the anti-falling steel wire rope 25 increases, the internal gear of the anti-falling device 23 rotates at an accelerated speed, and the pawl makes a centrifugal movement to engage the ratchet, thus quickly completing self-locking and realizing anti-falling.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
