Description

Automatic carding device for main cable strands Technical Field The invention belongs to the technical field of bridge construction, and relates to an automatic main cable strand combing device. Background The main cable is used as a key stress member of the suspension bridge, and the arrangement regularity of the cable strands plays a vital role in the overall structural performance and the service life of the suspension bridge. In the erection process of the main cable of the suspension bridge, the strands consisting of a plurality of high-strength steel wires are required to be precisely arranged and combined so as to ensure that the mechanical properties of the main cable are uniform and stable and meet the design requirements. In the production and actual use process, because the number of the strands is numerous and the length is long, if the strands are not effectively arranged, the phenomena of strand torsion, intersection and the like are very easy to occur. These problems can lead to uneven stress on the main cable, localized stress concentration, and serious influence on structural safety and durability of the suspension bridge. For example, twisting of the strands may increase friction between the wires, accelerate wear and fatigue damage of the wires, and crossing may damage the mechanical transmission path originally designed by the strands, reducing the load-bearing capacity and overall rigidity of the main cable. The main solution is to separate the strands by groups by combing the sheets by searching and looking up the related data. When the main cable is erected, the cable combing plate is arranged at a preset position so as to limit the displacement of the cable strand and maintain the relative position relation. For example, in some early suspension bridge constructions, simple cable combing plate devices were used in the construction of main cables, and the cable combing plates are of a flat plate structure, and the cable strands are separated by pre-arranging clamping grooves on the main cables and clamping the cable combing plates into the clamping grooves. However, this approach easily results in misalignment of the mounting positions of the comb plates during actual operation, thereby affecting the strand alignment effect. In addition, in the process of sequencing the strands, the rope combing plates are mainly carried out between the strands in a manual knocking mode, and the strands can be positioned to a certain extent by manually knocking the strands into the main cable, but the method has a plurality of defects. Meanwhile, the manual operation efficiency is low, the labor intensity is high, and the integral deviation of strand arrangement is increased along with the accumulation of construction errors, so that the quality of a main cable is affected. In summary, the existing method for separating strands by adopting the comb rope plates and manually knocking the strands into the main cable solves the problem of twisting and crossing the strands to a certain extent, but has the defects of difficult control of precision, easiness in damaging the strands, low efficiency, high labor intensity and the like. Therefore, it is necessary to develop an automatic main cable strand combing device to overcome the defects of the prior art and realize efficient, accurate and nondestructive main cable strand combing operation. Disclosure of Invention The invention provides an automatic carding device for main cable strands, which solves the problems of low efficiency and high labor intensity of the existing manual knocking mode, reduces the labor intensity, realizes the automation and the high efficiency of the main cable strand carding process, and meets the requirements of large-scale suspension bridge construction and reduces the construction cost. In order to solve the problems, the invention adopts the following technical scheme: The automatic cable carding device for the main cable strands comprises a base, wherein a fixing seat is arranged on the base, a plurality of hydraulic cylinders are arranged on the fixing seat, a cable carding plate is arranged on each hydraulic cylinder, the cable carding plate is not directly connected with the hydraulic cylinders, the cable carding plate is pushed into the cable strands to be separated and positioned through the expansion and contraction of the hydraulic cylinders, a fixing frame is arranged on one side of the cable carding plate, the cable strands are arranged on the fixing frame, and the cable strands are arranged and limited and fixed through the fixing frame and the cable carding plate. The principle of the scheme is that the fixing seat provides a stable supporting foundation for the whole device, the carding plate is not directly connected with the hydraulic cylinder, so that the device cannot generate additional stress concentration and vibration transmission due to rigid connection of the carding plate and the hydraulic cylinder in th
