Description

Technical Field

[0001] The present invention relates to the field of power transmission towers, and more particularly to a power transmission tower that is convenient to climb. Background Art

[0002] Transmission line towers are generally divided into five types according to their shapes: wine glass type, cat head type, upper type, dry type, and barrel type. According to their uses, there are tension towers, straight towers, corner towers, phase conversion towers (towers for changing the phase position of conductors), terminal towers, and crossing towers, etc. Their structural characteristics are that various tower types belong to space truss structures, and the members are mainly composed of single equal-angle steel or combined angle steel. The materials generally use two types, Q235 (A3F) and Q345 (16Mn). The connection between members uses rough bolts, and the connection is achieved by the shear force of the bolts. The whole tower is composed of angle steel, connecting steel plates, and bolts. Individual components such as tower feet are welded by several steel plates into a combined component. Therefore, hot-dip galvanized anti-corrosion, transportation, and construction erection are extremely convenient. For towers with a height below 60m, a footrest is provided on one of the main members of the tower as a climbing frame to facilitate the tower climbing operation of construction workers.

[0003] Although there are ladders on the surface of existing power transmission towers, in order to prevent unauthorized climbing, the lower end of the ladder is more than three meters above the ground. This results in that the staff still needs to carry a ladder used to connect the ladder, which is very inconvenient for work. At the same time, the climbing frame of the power transmission tower is mainly fixed on the main member rod by means of bolt locking. After long-term use or being eroded by rainwater, it is easy to be damaged, reducing the safety performance. It is necessary to design a power transmission tower that is convenient to climb to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose a power transmission tower that is convenient to climb, so as to solve the problems of safety and convenience in the above technical solutions.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A power transmission tower that is convenient to climb, including a main member rod, on the upper part of the left side of the main member rod, a plurality of fixed climbing units are fixedly connected at equal intervals, on the bottom of the left side of the main member rod, a plurality of dismountable climbing units are fixedly connected at equal intervals, and on the front side of the main member rod, a plurality of safety clamping units are fixedly connected; The fixed climbing unit is used for a climbing device fixedly installed on the main member rod, the dismountable climbing unit is used for a climbing device that can be disassembled on the main member rod, and the safety clamping unit is used for a safety device fixed on the main member rod; Each of the fixed climbing units includes a first fixed rod and a second fixed rod, and each of the dismountable climbing units includes a third fixed rod.

[0006] Further, each of the fixed climbing units includes a first connecting plate. In the middle of the left side of the first connecting plate, a first fixing rod is fixedly arranged. At the upper and lower parts of the left side of the first connecting plate, first connecting bolts are fixedly arranged. On the right side of the first connecting plate, a second connecting plate is arranged. In the middle of the right side of the second connecting plate, a second fixing rod is fixedly arranged. At the upper and lower parts of the first connecting plate and the second connecting plate, they are fixedly connected to the main material rod through second connecting bolts; On the left side of the main material rod, a number of first connecting holes, second connecting holes and third connecting holes are equidistantly arranged. The first fixing rods are all inserted into the corresponding first connecting holes, the first connecting bolts are all threaded into the corresponding second connecting holes, and the second connecting bolts are all threaded into the corresponding third connecting holes.

[0007] Further, each of the dismountable climbing units includes a fixing block and a third fixing rod. At the upper and lower parts of the fixing block, connecting side ears are arranged. In the middle of the fixing block, a first jack is arranged. At the right end of the third fixing rod, a second connecting hole is arranged. A plug bolt is slidably connected inside the first jack. In the middle of the connecting side ears, third connecting bolts are arranged; On the bottom left side of the main material rod, a number of fourth connecting holes and fifth connecting holes are equidistantly arranged. The third fixing rods are all inserted into the corresponding fourth connecting holes, and the third connecting bolts are all threaded into the corresponding fifth connecting holes.

[0008] Further, the safety clamping unit includes a clamping frame and a number of fixing parts. On the front side of each fixing part, a clamping block is arranged. The inner sides of the clamping blocks are all clamped with the rear side of the clamping frame. At the left and right ends of the front side of the fixing parts, fourth connecting bolts are arranged. In the middle of the clamping blocks, fifth connecting bolts are arranged; On the front side of the main material rod, a number of sixth connecting holes are equidistantly arranged. The fifth connecting bolts are all threaded into the corresponding sixth connecting holes.

[0009] Further, the fixed climbing units are located more than 3m above the main material rod and are arranged every 40cm. The dismountable climbing units are all located below 3m of the main material rod and are arranged every 50cm.

[0010] Further, a positioning hole is arranged at the right end inside the fixing block. The diameter of the positioning hole is the same as the diameter of the third fixing rod, and the depth of the positioning hole is 3cm.

[0011] Further, one fixing part is arranged every 1m, and the clamping frame is a structure welded every 3m.

When a single fixed climbing unit fails, it can be replaced in time. By disassembling the climbing unit and installing it when in use, a fulcrum is provided for climbers within a range of less than 3m. At the same time, the third fixed rod can be removed when not in use to prevent irrelevant personnel from climbing, and the third fixed rod can be stored in the power tower in a centralized manner. Climbers do not need to carry a ladder for connecting the ladder when using it, which increases convenience.

[0014] 2. During the climbing process, climbers can reliably connect safety ropes and other protective equipment to the safety card unit, so they can obtain effective safety protection no matter where they work. At the same time, dense and uniform fixings reduce the risk of falling from all directions, providing a solid guarantee for the life safety of climbers.

[0015] 3. In terms of installation, the fixing block, the third fixing rod, the plug and the third connecting bolt cooperate with each other, so that the climbing device can be quickly and conveniently installed on the main material rod, and the connection is firm; at the same time, when facing different power towers, it can be installed and arranged according to actual needs, which is convenient for adjusting the structural layout of the tower, greatly enhancing the applicability and versatility of the power tower; in addition, the positioning hole on the right end of the inner side of the fixing block is precisely matched with the third fixing rod, which further improves the accuracy and stability of the installation and ensures the safety of climbers when climbing at the bottom of the tower.
