Description
Technical Field
The invention relates to the field of electric power overhaul of a power transmission iron tower in an electric power system, in particular to a guide rail frame for tower climbing equipment.
Background
Lifting equipment used on large-scale transmission towers in the power industry comprises three types, namely a well type elevator, a construction elevator and a tower climbing machine. These types of lifting devices require fixed guide rails to operate, and therefore the guide rails must be mounted on the tower as a fixed installation. Due to the large weight of the equipment and the structure of the guide rail, the existing guide rail is generally heavy in structure, the guide rail has large influence on the safety of an iron tower, and the use of the lifting equipment in the power industry is indirectly limited.
The application of the rail frame of lifting equipment such as a well elevator, a construction elevator and an iron tower climbing machine on the power transmission iron tower has the following limitations:
firstly, the guide rail frame has large structure size and great influence on the safety of an iron tower;
due to the fact that lifting equipment is heavy, guide rail frame structures of a pit elevator, a construction elevator and an iron tower climbing machine are heavy, the cross section size is large, the wind shielding area of the guide rail frame is large, and the safety of the iron tower is greatly affected. Therefore, the equipment cannot be installed and applied on a steel tower on a general line.
Secondly, the guide rail frame is expensive to manufacture;
the cost of the guide rail frame accounts for the main part of the total cost of the equipment, and the existing equipment has the defects that the cost of the guide rail frame is high due to the complex structure and the large section size of the guide rail frame, so that the equipment cannot be applied in a large range.
The guide rail frame has poor corrosion resistance;
the existing guide rail frame adopts an involute gear and rack transmission mode, the transmission mode has high precision requirement, poor corrosion resistance and unreasonable corrosion prevention measures, so that the equipment is difficult to maintain and frequently breaks down, and the service life is influenced. The use of lifting equipment in the power industry is under outdoor conditions, the influence on the transmission of the gear and the rack can be avoided under natural conditions such as wind blowing, sun exposure, rain, sand and dust, and the involute gear and rack transmission form is extremely easy to be damaged under the conditions, so that the service life of the gear and the rack is directly influenced. At present, an application unit can regularly coat lubricating oil on the surfaces of the gear and the rack for maintenance, but the maintenance work is complicated and high in cost, and the lubricating oil can adhere sand grains to the surfaces of the gear and the rack and can cause more serious damage to the gear and the rack.
The guide rail frame has an unreasonable structure;
the guide rail frame of the existing equipment welds the guide rail for equipment operation and the profile material with stress effect together, a sectional butt joint type structure is adopted, the length of each section of guide rail frame is about 1500mm, namely the guide rail frame is formed by splicing small guide rail frames with standard length of about 1500mm, wherein the guide rail frames are welded together by the guide rail and the profile material. The connection surfaces between the small guide rail frames in the structural form are in point connection, each surface is provided with four connection points with small contact areas, the four connection points are required to be integrally leveled when the small guide rail frames are processed, and the processing of the guide rail frames is complex. In addition, each joint face of the small rail frame is a stress concentration point, resulting in weak overall strength and rigidity of the rail frame. In addition, the cracking mode has higher requirement on the processing precision of each section of small guide rail bracket.
