Fishbone ladder stand adopting closed structure

Abstract

The invention belongs to the technical field of mobile communication, and discloses a fishbone crawling ladder adopting a closed structure, and crawling nails adopt round steel components and are welded into a whole in a closed connection mode. The crawling nails are welded on the crawling ladder main rod, and meanwhile, the tails of the crawling nails are bent and upwarped and are staggered at equal intervals, so that the fishbone type crawling ladder is formed. According to the fishbone crawling ladder with the closed structure, the crawling nails adopt the closed structure, so that the foot treading contact area of high-altitude operation personnel in the installation and maintenance process can be increased, the phenomena of missing treading and slipping caused by wet and slippery crawling ladders due to rainy and snowy weather are avoided, the sole pressure is reduced, and the potential safety hazard is effectively reduced. Meanwhile, a closed structure is adopted, so that the aerial working personnel can buckle the safety buckle in the closed climbing nail, and compared with the original non-closed climbing nail form, the safety in the construction and maintenance process is improved.

Description

Technical Field

[0001] The invention belongs to the technical field of mobile communications. Background Art

[0002] In today's society, as my country's communications industry matures, the construction of communication base stations has attracted more and more attention to the safety of tower installation and construction. The current form of ladder is to fix the climbing nails of a single round steel component on the main pole of the ladder alternately at equal distances, and at the same time, the tail of the climbing nail is tilted upward, which is a non-closed form of climbing nail. During the installation and maintenance of this type of climbing nail, high-altitude workers cannot buckle the safety buckle on the climbing nail, which cannot play a protective role and is prone to slippage. At the same time, when encountering adverse weather such as rain and snow, the single round steel component is slippery and icy. During the stepping process, the foot area is small, and there are safety hazards for high-altitude workers. The expansion of the scale of base station construction has put forward higher requirements for the safety of workers. In the process of tower workers climbing the tower, they generally choose to wrap the safety belt around the tower body for safety protection, which is difficult to operate and affects the climbing speed. At the same time, the climbing nail of the old single-tube tower fishbone ladder is a slender iron rod. In order to facilitate the operation of the tower workers when climbing the tower, the safety belt hook may be hung on the climbing nail, which is easy to slip outward. In addition, the climbing spikes are long and slender in shape. When carrying heavy objects up the tower, the tower workers' feet will be under great pressure, which makes them prone to slipping and has a low safety factor. Summary of the invention

[0003] The present invention provides a herringbone ladder with a closed structure, which solves the problem of the convenience and safety of using a safety belt during the climbing and installation process of tower workers, improves the work efficiency and comfort of tower workers, and reduces the probability of accidents. The necessity and feasibility of improving the climbing nails of the herringbone ladder are verified. By improving the herringbone ladder, the safety of tower workers when climbing a single-tube tower is improved, the climbing speed and comfort are increased, the convenience of using a safety belt is enhanced, and tower workers can use the safety belt easily and safely, thereby reducing the probability of accidents and improving work efficiency.

[0004] The present invention uses steel structural components, and the climbing nail part uses round steel components, which are connected in a closed manner and welded to form a whole. The climbing nails are welded to the main rod of the ladder, and the tails of the climbing nails are bent upward and arranged at equal intervals to form a herringbone ladder. The fixed support part is fixed by a clamp, and the climbing nail part is connected to the main rod of the ladder by welding. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0009] like Figure 1-Figure 2 As shown, this embodiment provides a herringbone ladder with a closed structure, including: foot nails 1, which are welded to the main pole to form a closed structure, the main pole is bolted to the angle steel 3 through the steel plate 2, and the angle steel 3 is welded to the tower body. The tail of the foot nails 1 is upturned and arranged at equal distances to form a herringbone ladder.

[0010] The working principle and beneficial effects of the above technical solution are:

[0011] The climbing nail 1 is a round steel member with a diameter of 16 mm, which is connected in a closed way and welded into a whole. The climbing nail 1 is welded to the main rod of the ladder, and the tail of the climbing nail 1 is bent and tilted upward, and arranged at equal intervals to form a fishbone ladder. The fixed support part is fixed with a steel plate 2 and an angle steel 3 clamp, and the angle steel 3 is welded to the tower body. The climbing nail 1 part is welded to the main rod of the ladder, and the tail of the climbing nail is tilted upward. The size of the extended part is 164 mm, the width is 60 mm, and the size of the tilted part is 30 mm.

[0012] The present invention adopts a closed climbing spike, which effectively increases the contact area of ​​the workers' feet and avoids stepping on empty space and slipping caused by the workers themselves or adverse weather. At the same time, the workers can buckle the safety rope into the closed climbing spikes, which increases the safety measures in the construction and maintenance process and provides safety protection. Compared with the open ladder, the closed structure can effectively prevent the user from being injured due to accidental falls during use, thereby improving the safety of use. The closed design enhances the overall structural strength of the ladder, making the ladder more stable when bearing weight and less prone to deformation or damage. Taking into account the fatigue that may be caused by long-term climbing, the design adopts a closed design and pays attention to the width, material and comfort of the climbing spikes to reduce the physical exertion and discomfort of the workers.
