Description

Free steering platform supporting tool device of flat car Technical Field The utility model relates to the field of steering of workshop part materials, in particular to a free steering platform supporting tool device of a flat car. Background In an industrial plant environment, the manner and efficiency of material transport is critical to the overall production process. The types, technical features and the respective disadvantages of the main stream plant material transport will be described in detail below. The rail type electric flat car has various types, including KPD low-voltage rail power supply type, KPX storage battery type, KPT towing rope type and the like. These different types of flatcars are suitable for heavy-duty transportation on a fixed path, with a load range of between 1 and 500 tons, commonly found in workshops such as metallurgy, mechanical manufacturing, etc. In a metallurgical workshop, a large amount of metal raw materials and finished products need to be transported, and the rail-type electric flat car can easily cope with the carrying work of heavy-duty materials by virtue of the strong carrying capacity. From the technical advantage aspect, the rail-mounted electric flat car is accurate in positioning, and can accurately transport materials to a designated position, so that the rail-mounted electric flat car is particularly important to production links with strict requirements on the material placement position. Meanwhile, the high-load material conveying device is high in load, can meet the conveying requirement of large-scale materials, is stable in operation, can ensure the safety of the materials in the conveying process, and reduces damage caused by shaking. There are also various types of trackless electric flat cars/tractors, such as BWP trackless flat cars, battery tractors, etc. The transportation equipment is provided with a solid tire and an electromagnetic braking system, and is suitable for flexible production lines and multi-workshop connection scenes. In some electronic product manufacturing workshops, the production process may be frequently adjusted according to the order demands, and the trackless electric flat carriage can flexibly transport materials between different production areas so as to meet the demands of flexible production. The technical advantage is that rails do not need to be paved, so that the construction cost and time in the earlier stage are greatly saved. Meanwhile, the speed of up to 15km/h is supported, climbing and steering operations can be performed, and the flexibility and the adaptability are high. Limitations of different modes of transportation-the limitations of track-dependent devices are evident. Firstly, the problem of path solidification is that the track needs to be paved in advance, when an enterprise needs to modify a production line, the cost of dismantling and re-paving the track is high, and the modification period is long, so that the normal production progress of the enterprise can be seriously affected. Secondly, the flexibility is insufficient, and temporary route adjustment cannot be adapted. If an emergency situation occurs in the production process and the material transportation route needs to be changed, the track type equipment cannot always meet the requirements directly, and trans-regional transportation needs to be completed by means of transfer equipment, so that the transportation cost is increased, and the transportation efficiency is reduced. Steering efficiency bottleneck of trackless vehicles: The steering operation depends on manpower, and at present, the trackless flatcar can freely move, but still needs to be pushed, pulled and positioned manually when the transportation direction is adjusted. For heavy vehicles, this process requires multiple people to cooperate, which is time consuming and labor consuming and increases labor costs. For example, in some large equipment manufacturing plants, 5-6 workers may be required to co-operate when handling trackless flatcars of heavy parts, which undoubtedly increases the human burden on the enterprise. The navigation precision problem is that part of the trackless vehicles rely on manual visual operation, which easily causes the vehicles to deviate from the paths in the transportation process and needs to be corrected repeatedly. In some workshops with high requirements on transportation precision, such as precision instrument manufacturing workshops, the problem of navigation precision can lead to inaccurate material transportation and influence the production quality of products. The energy and maintenance costs are high, and the trackless vehicles of the battery model need to be charged frequently, which can affect the continuous operation capability of the vehicle. Moreover, the battery life is short, about 2-3 years, which requires the enterprise to replace the battery periodically, increasing the cost of use. For track equipment, maintenance work is c
